  abstract  = {This work presents the first ILT observations of high redshift blazars and their study in terms of jet evolution, morphology, and interaction with the surrounding medium. Each of these represents a highly topical area of astronomywith a large number of open questions. To better understand Active Galactic Nuclei (AGN) and their fundamental inner workings, new techniques are needed to exploit the full potential of the next generation of radio interferometers. Some of these tools are presented here and applied to one of the latest generation of software radio telescopes. A major focus of the studies presented is on the unification model, where the observed blazars are discussed for their properties to be rotated counterparts of Fanaroff-Riley Class II (FR-II) radio galaxies, when classified as Flat Spectrum Radio Quasars (FSRQs). In addition, multiwavelength information has been included in the analysis. Both studies are feasibility studies that will serve as a basis for future similar studies. The characteristics discussed and their interpretation do not allow conclusions to be drawn for their respective populations. However, by applying them to a larger number of targets, population studies will be possible. The first chapters introduce the necessary topics, AGN, principles of radio observations and ILT, in the necessary depth to provide the reader with a solid knowledge base. They are particularly important for understanding the current limits and influences of uncertainties in the observation, calibration and imaging process. But they also shed light on realistic future improvements. A particular focus is on the development and evolution of the LOw-Frequency ARray (LOFAR)-Very Long Baseline Interferometry (VLBI) pipeline. With the tools at hand, the first study addresses the high redshift blazar S5 0836+710 \$(z=2.218)\$, which has been observed at various wavelengths and resolutions. It has a disrupted one-sided jet with an associated extended region further out. Despite the excellent wavelength coverage, only the additional ILT observations provided a complete picture of the source. With the data, the extended region could be classified as a hotspot moving at slightly relativistic speeds.. With the ILT data it was also possible to extract the flux of the core region of the AGN, and in projection to reveal the mixed counter-hotspot behind it. This also allowed constraints on jet parameters and environmental properties to be modelled, which were previously inconclusive. Technically, this study shows that the ILT can be used as an effective VLBI array for compact sources with small angular scales. However, the detection of faint components beyond redshifts of \$z=2\$ may require the capabilities of the Square Kilometre Array (SKA) to provide a significant number of detections to enable statistical conclusions. The second study uses a much improved calibration pipeline to analyse the high redshift blazar GB1508+5714 \$(z=4.30)\$. The ILT data revealed a previously unseen component in the eastern direction. A spectral index map was generated from the Karl G. Jansky Very Large Array (VLA) data, showing spectral index values of \$-1.2_{-0.2}^{+0.4}\$ for the western component, steeper than \$-1.1\$ for the eastern region, and \$0.023 \pm 0.007\$ for the core. Using the information provided by the ILT observation, as well as multi-wavelength information from other observations ranging from the long radio wavelengths to the \$\gamma\$ regime, four models were developed to interpret the observed flux with different emission origins. This also allowed to test a proposed interaction channel of the electrons provided by the jet, to cool off via inverse compton scattering with the Cosmic Microwave Background (CMB) photons, rather than by the usual synchrotron emission. This is referred to as cmb quenching in the literature, which could be shown in the study, to be necessary in any case. Finally, one of the four models was considered in which the hotspots in the detected components are unresolved and mixed by the lobe emission, with the X-ray emission coming from the lobes and partially mixed by the bright core region. The results of this preferred model are consistent with hotspots in a state of equipartition and lobes almost so. The study shows that high redshift blazars can be studied with the ILT, and expanding the sample of high redshift blazars resolved at multiple frequencies will allow a statistical study of the population. Finally, this work successfully demonstrates the powerful capabilities of the ILT to address questions that were previously inaccessible. The current state of the LOFAR-VLBI pipeline, when properly executed, allows work on the most challenging objects and will only improve in the future. In particular, this gives a glimpse of the possibilities that SKA will bring to astronomy.},

  abstract  = {The expression of the MYC proto-oncogene is elevated in a large proportion of patients with pancreatic ductal adenocarcinoma (PDAC). Previous findings in PDAC have shown that this increased MYC expression mediates immune evasion and promotes S-phase progression. How these functions are mediated and whether a downstream factor of MYC mediates these functions has remained elusive. Recent studies identifying the MYC interactome revealed a complex network of interaction partners, highlighting the need to identify the oncogenic pathway of MYC in an unbiased manner. In this work, we have shown that MYC ensures genomic stability during S-phase and prevents transcription-replication conflicts. Depletion of MYC and inhibition of ATR kinase showed a synergistic effect to induce DNA damage. A targeted siRNA screen targeting downstream factors of MYC revealed that PAF1c is required for DNA repair and S-phase progression. Recruitment of PAF1c to RNAPII was shown to be MYC dependent. PAF1c was shown to be largely dispensable for cell proliferation and regulation of MYC target genes. Depletion of CTR9, a subunit of PAF1c, caused strong tumor regression in a pancreatic ductal adenocarcinoma model, with long-term survival in a subset of mice. This effect was not due to induction of DNA damage, but to restoration of tumor immune surveillance. Depletion of PAF1c resulted in the release of RNAPII with transcription elongation factors, including SPT6, from the bodies of long genes, promoting full-length transcription of short genes. This resulted in the downregulation of long DNA repair genes and the concomitant upregulation of short genes, including MHC class I genes. These data demonstrate that a balance between long and short gene transcription is essential for tumor progression and that interference with PAF1c levels shifts this balance toward a tumor-suppressive transcriptional program. It also directly links MYC-mediated S-phase progression to immune evasion. Unlike MYC, PAF1c has a stable, known folded structure; therefore, the development of a small molecule targeting PAF1c may disrupt the immune evasive function of MYC while sparing its physiological functions in cellular growth.},

Hierf{\"u}r wurde retrospektiv und monozentrisch das Auftreten der genannten postoperativen Ereignisse in zwei Zeitr{\"a}umen untersucht. Das erste Studienintervall erstreckte sich von Januar 2011 bis Dezember 2014 und spiegelt die Ereignisraten vor der internen Leitlinien{\"a}nderung wider. Es wurden 263 Personen eingeschlossen. Das zweite Intervall begann im Januar 2017 und endete im Dezember 2019, in diesem wurden 271 Personen untersucht. Zwischen diesen beiden Zeitr{\"a}umen wurde eine {\"u}berarbeitete klinikinterne Bridging-Leitlinie etabliert, welche an das individuelle thromboembolische Risiko, Alter, Gewicht und die Nierenfunktion der Patientinnen und Patienten angepasst war. Postoperative Major- (8.4\% vs. 4.1\%, p=0.039) und Minor-Blutungen (13.7\% vs. 6.3\%, p=0.004) nahmen im zweiten Intervall signifikant ab, w{\"a}hrend das thromboembolische Risiko weiterhin niedrig blieb (0.8\% vs. 1.1\%, p=1). Außerdem zeigte sich, dass es zu keiner signifikanten Zunahme der Mortalit{\"a}t, der Reoperationen, der L{\"a}nge des postoperativen station{\"a}ren Aufenthalts oder der Erythrozytenkonzentrat-Transfusionen kam. Die Ergebnisse dieser Arbeit zeigen, dass die differenzierte Bridging-Leitlinie f{\"u}r die Allgemein- und Viszeralchirurgie mit einer signifikant erniedrigten Blutungsrate assoziiert ist und eine Anpassung des Bridgings an die patientenspezifischen Risikofaktoren wichtig ist.},

Ziel dieser Arbeit war es, ein kulturelles Screeningverfahren f{\"u}r Linezolid-resistente Enterokokken (LRE) zu entwickeln und dieses anschließend im Routinescreening des Universit{\"a}tsklinikums W{\"u}rzburg zu etablieren. Es wurde ein Verfahren entwickelt, welches sich aus einem Anreicherungsschritt mit 3 mg/l Linezolid versetzter selektiver Enterococcosel-Bouillon und einer anschließenden Subkultivierung auf Linezolid-Enterococcosel-Agar mit 4 mg/l Linezolid zusammensetzt. In einer Simulation von klinischen Bedingungen zeigte sich eine gute Sensitivit{\"a}t und Spezifit{\"a}t. Das entwickelte Screeningverfahren wurde mit einem geringen Sensitivit{\"a}tsverlust und ohne zus{\"a}tzliche Belastung f{\"u}r die Patienten in das bestehende Routinescreening f{\"u}r Vancomycin-resistente Enterokokken des Universit{\"a}tsklinikums W{\"u}rzburg eingegliedert.

  abstract  = {Fabry disease is an X-linked inherited, progressive disorder of lipid metabolism resulting from the deficient activity of the enzyme α-galactosidase. Enzyme replacement therapy (ERT) with recombinant agalsidase, with intravenous infusions of either agalsidase beta or agalsidase alfa, is available and clinical experience now exceeds 15 years. There are very few randomised, placebo-controlled clinical trials evaluating the outcomes of ERT. Data are often derived from observational, registry-based studies and case reports. Pooled analysis of data from different sources may be limited by the heterogeneity of the patient populations, outcomes and treatment. Therefore, comprehensive systematic literature reviews of unpooled data are needed to determine the effects of ERT on disease outcomes. A systematic literature search was conducted in the Embase and PubMed (MEDLINE) databases to retrieve original articles that evaluated outcomes of ERT in patients with Fabry disease; the outcome data were analysed unpooled. The literature analysis included the full range of published literature including observational studies and case series/case reports. Considerable heterogeneity was found among the studies, with differences in sample size, statistical methods, ERT regimens and patient demographic and clinical characteristics. We have demonstrated the value of performing an unpooled systematic literature review of all published evidence of ERT outcomes in Fabry disease, highlighting that in a rare genetic disorder like Fabry disease, which is phenotypically diverse, different patient populations can require different disease management and therapeutic goals depending on age, genotype, and disease severity/level of organ involvement. In addition, these findings are valuable to guide the design and reporting of new clinical studies.},

  abstract  = {Recent research revealed the superiority of artificial intelligence over dermatologists to diagnose melanoma from images. However, 30-50\% of all melanomas and more than half of those in young patients evolve from initially benign lesions. Despite its high relevance for melanoma screening, neither clinicians nor computers are yet able to reliably predict a nevus' oncologic transformation. The cause of this lies in the static nature of lesion presentation in the current standard of care, both for clinicians and algorithms. The status quo makes it difficult to train algorithms (and clinicians) to precisely assess the likelihood of a benign skin lesion to transform into melanoma. In addition, it inhibits the precision of current algorithms since 'evolution' image features may not be part of their decision. The current literature reveals certain types of melanocytic nevi (i.e. 'spitzoid' or 'dysplastic' nevi) and criteria (i.e. visible vasculature) that, in general, appear to have a higher chance to transform into melanoma. However, owing to the cumulative nature of oncogenic mutations in melanoma, a more fine-grained early morphologic footprint is likely to be detectable by an algorithm. In this perspective article, the concept of melanoma prediction is further explored by the discussion of the evolution of melanoma, the concept for training of such a nevi classifier and the implications of early melanoma prediction for clinical practice. In conclusion, the authors believe that artificial intelligence trained on prospective image data could be transformative for skin cancer diagnostics by (a) predicting melanoma before it occurs (i.e. pre-in situ) and (b) further enhancing the accuracy of current melanoma classifiers. Necessary prospective images for this research are obtained via free mole-monitoring mobile apps.},

Gleichwohl gibt es bislang f{\"u}r diese systolischen Zeitintervalle keine Normwerte. Die vorliegende Arbeit analysierte echokardiographische Daten von 4965 ProbandInnen der STAAB-Studie, einer umf{\"a}nglich ph{\"a}notypisierten populationsbasierten Kohortenstudie mit dem Ziel der Erstellung von Normwerten f{\"u}r die systolischen Zeitintervalle sowie der Identifizierung und Quantifizierung ihrer Determinanten mittels multivariable Regressionsanalysen. Aufgrund der starken Abh{\"a}ngigkeit der SET von der Herzfrequenz wurde die herzfrequenzkorrigierte SETc eingef{\"u}hrt, die in Anlehnung an die QTc-Zeit nach Fridericia berechnet wurde ("SET" /∛("RR-Intervall" )). Die Normwerte wurden anhand der gesunden Untergruppe (definiert durch Abwesenheit von kardiovaskul{\"a}ren Risikofaktoren oder Erkrankungen; N=966) aus STAAB generiert. Dem starken Einfluss von Geschlecht und Alter wurde dabei Rechnung getragen, indem f{\"u}r SET, SETc und pET alters- und geschlechtsspezifische Referenzwerte berechnet wurden. SETc war stark korreliert mit linksventrikul{\"a}rer Ejektionsfraktion sowie enddiastolischem Volumen und Schlagvolumen. Zudem zeigte sich ein deutlicher Zusammenhang von SETc mit spezifischen Markern der Nachlast (Ea und Ees). Aus der großen Liste der klinischen Marker, die in STAAB erhoben wurden, ergab sich eine gr{\"o}ßere Anzahl von Einflussfaktoren. Bedeutsame Determinanten der systolischen Zeitintervalle waren insbesondere das metabolische Syndrom (sowie dessen Komponenten), das Rauchverhalten und die Einnahme von β Blockern. Die Ergebnisse zeigen, dass die systolischen Zeitintervalle, insbesondere SETc, reliable Informationen {\"u}ber das kardiale Kontraktionsverhalten liefern k{\"o}nnen. Derzeit werden neue Substanzklassen untersucht, die unter anderem {\"u}ber die Modifizierung von SET wirken sollen. Hier zu nennen sind insbesondere Myosin-Aktivatoren bei Herzinsuffizienz mit reduzierter Pumpfunktion wie zum Beispiel Omecamtiv Mecarbil oder Myosin-Inhibitoren bei Hypertropher Obstruktiver Kardiomyopathie. Die hierzu laufenden Studien betrachten auch die Effekte dieser Medikamente auf die systolischen Zeitintervalle als bedeutsame Surrogate der klinischen Effekte und letztlich der Prognose.

Developments since the last public release include increased number of species and gene essentiality data sets, inclusion of non-coding essential sequences and genes with intermediate essentiality statuses. In addition, we included 16 essentiality data sets from cancer cell lines, corresponding to 9 human cancers; with OGEE, users can easily explore the shared and differentially essential genes within and between cancer types. These genes, especially those derived from cell lines that are similar to tumor samples, could reveal the oncogenic drivers, paralogous gene expression pattern and chromosomal structure of the corresponding cancer types, and can be further screened to identify targets for cancer therapy and/or new drug development.

  abstract  = {Fusobacterium nucleatum is an emerging cancer-associated bacterium belonging to the Fusobacteriota phylum, which is evolutionary distant from all model bacteria. Recent analysis generated global fusobacterial RNA maps, which enabled the discovery of 24 small noncoding RNAs (sRNAs) in F. nucleatum. Notably, the σE-dependent sRNA FoxI and FoxJ act as a posttranscriptional regulator of several cell envelope proteins. The σE-dependent sRNAs in Escherichia coli and Salmonella require the RNA chaperone Hfq for their functions. Intriguingly, F. nucleatum seems to have no homologs of the three common RNA-binding proteins (RBPs) CsrA, Hfq and ProQ. However, it remains unclear if other families of RBPs act in concert with FoxI, FoxJ and other fusobacterial sRNAs. This work has successfully established a 14-mer capture tagged-sRNA affinity purification procedure initially using 6S RNA as a proof-of-concept. Applying this method to 19 different F. nucleatum sRNAs led to a comprehensive mapping of sRNA-binding proteins in this bacterium. This screen identified a total of 75 proteins significantly enriched across all sRNAs and prominent in ribosomal proteins, uncharacterized proteins and enzymes associated with metabolism. This work further focused on the homologs of two KH domain proteins KhpA and KhpB, which were recently recognized as global RBPs in various Gram-positive bacteria such as Streptococcus pneumoniae, Clostridioides difficile, and Enterococcus faecalis. Comparative analyses revealed conserved domain composition and gene synteny of KhpA and KhpB across F. nucleatum, S. pneumoniae, C. difficle and E. faecalis, indicating conserved roles of these proteins in bacteria. Further protein-protein interaction assays and global RNA targets profiling demonstrated that KhpA and KhpB form dimers and act together as broad RBPs, binding to sRNAs, mRNAs and tRNAs in F. nucleatum. Further functional characterizations unveiled that KhpA/B are required for the growth of F. nucleatum under nutrient limitation conditions and impact cell morphology. Additionally, the two RBPs also influence global gene expression in F. nucleatum affecting various bacterial physiological processes, including ethanolamine utilization. In summary, this work established a sRNA-centric approach for screening sRNA-binding proteins in F. nucleatum. Further, the assay could be applied in other non-model organisms and is feasible to screen multiple sRNA baits in parallel for sRNA-interactors. By applying this procedure to nearly all known fusobacterial sRNAs, this work generated an extensive map of sRNA-interacting proteins in F. nucleatum. Molecular and genetic studies identified that KhpA/B act as major RBPs and gene regulators in F. nucleatum, representing important first steps in elucidating key players of post-transcriptional control at the root of the bacterial phylogenetic tree.},

  abstract  = {Attention-deficit/hyperactivity disorder (ADHD) is highly heritable and the most common neurodevelopmental disorder in childhood. In recent decades, it has been appreciated that in a substantial number of cases the disorder does not remit in puberty, but persists into adulthood. Both in childhood and adulthood, ADHD is characterised by substantial comorbidity including substance use, depression, anxiety, and accidents. However, course and symptoms of the disorder and the comorbidities may fluctuate and change over time, and even age of onset in childhood has recently been questioned. Available evidence to date is poor and largely inconsistent with regard to the predictors of persistence versus remittance. Likewise, the development of comorbid disorders cannot be foreseen early on, hampering preventive measures. These facts call for a lifespan perspective on ADHD from childhood to old age. In this selective review, we summarise current knowledge of the long-term course of ADHD, with an emphasis on clinical symptom and cognitive trajectories, treatment effects over the lifespan, and the development of comorbidities. Also, we summarise current knowledge and important unresolved issues on biological factors underlying different ADHD trajectories. We conclude that a severe lack of knowledge on lifespan aspects in ADHD still exists for nearly every aspect reviewed. We encourage large-scale research efforts to overcome those knowledge gaps through appropriately granular longitudinal studies.},

  abstract  = {Background \& Aims Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are increasingly a cause of cirrhosis and hepatocellular carcinoma globally. This burden is expected to increase as epidemics of obesity, diabetes and metabolic syndrome continue to grow. The goal of this analysis was to use a Markov model to forecast NAFLD disease burden using currently available data. Methods A model was used to estimate NAFLD and NASH disease progression in eight countries based on data for adult prevalence of obesity and type 2 diabetes mellitus (DM). Published estimates and expert consensus were used to build and validate the model projections. Results If obesity and DM level off in the future, we project a modest growth in total NAFLD cases (0-30\%), between 2016-2030, with the highest growth in China as a result of urbanization and the lowest growth in Japan as a result of a shrinking population. However, at the same time, NASH prevalence will increase 15-56\%, while liver mortality and advanced liver disease will more than double as a result of an aging/increasing population. Conclusions NAFLD and NASH represent a large and growing public health problem and efforts to understand this epidemic and to mitigate the disease burden are needed. If obesity and DM continue to increase at current and historical rates, both NAFLD and NASH prevalence are expected to increase. Since both are reversible, public health campaigns to increase awareness and diagnosis, and to promote diet and exercise can help manage the growth in future disease burden. Lay summary Non-alcoholic fatty liver disease and non-alcoholic steatohepatitis can lead to advanced liver disease. Both conditions are becoming increasingly prevalent as the epidemics of obesity and diabetes continue to increase. A mathematical model was built to understand how the disease burden associated with non-alcoholic fatty liver disease and non-alcoholic steatohepatitis will change over time. Results suggest increasing cases of advanced liver disease and liver-related mortality in the coming years.},

  abstract  = {Unprecedented urbanization in particular in countries of the global south result in informal urban development processes, especially in mega cities. With an estimated 1 billion slum dwellers globally, the United Nations have made the fight against poverty the number one sustainable development goal. To provide better infrastructure and thus a better life to slum dwellers, detailed information on the spatial location and size of slums is of crucial importance. In the past, remote sensing has proven to be an extremely valuable and effective tool for mapping slums. The nature of used mapping approaches by machine learning, however, made it necessary to invest a lot of effort in training the models. Recent advances in deep learning allow for transferring trained fully convolutional networks (FCN) from one data set to another. Thus, in our study we aim at analyzing transfer learning capabilities of FCNs to slum mapping in various satellite images. A model trained on very high resolution optical satellite imagery from QuickBird is transferred to Sentinel-2 and TerraSAR-X data. While free-of-charge Sentinel-2 data is widely available, its comparably lower resolution makes slum mapping a challenging task. TerraSAR-X data on the other hand, has a higher resolution and is considered a powerful data source for intra-urban structure analysis. Due to the different image characteristics of SAR compared to optical data, however, transferring the model could not improve the performance of semantic segmentation but we observe very high accuracies for mapped slums in the optical data: QuickBird image obtains 86-88\% (positive prediction value and sensitivity) and a significant increase for Sentinel-2 applying transfer learning can be observed (from 38 to 55\% and from 79 to 85\% for PPV and sensitivity, respectively). Using transfer learning proofs extremely valuable in retrieving information on small-scaled urban structures such as slum patches even in satellite images of decametric resolution.},

  abstract  = {Sand mines represent anthropogenically impacted habitats found worldwide, which bear potential for bee conservation. Although floral resources can be limited at these habitats, vegetation free patches of open sandy soils and embankments may offer good nesting possibilities for sand restricted and other bees. We compared bee communities as found in three reclaimed sand mines and at adjacent roadside meadows in Maryland, USA, over two years. Both sand mines and roadsides hosted diverse bee communities with 111 and 88 bee species, respectively. Bee abundances as well as richness and Shannon diversity of bee species were higher in sand mines than at roadsides and negatively correlated with the percentage of vegetational ground cover. Species composition also differed significantly between habitats. Sand mines hosted a higher proportion of ground nesters, more uncommon and more 'sand loving' bees similar to natural sandy areas of Maryland. Despite the destruction of the original pre-mining habitat, sand mines thus appear to represent a unique habitat for wild bees, particularly when natural vegetation and open sand spots are encouraged. Considering habitat loss, the lack of natural disturbance regimes, and ongoing declines of wild bees, sand mines could add promising opportunities for bee conservation which has hitherto mainly focused on agricultural and urban habitats.},

Exome sequencing was performed on the genomic DNA of an Iranian patient and his affected brother who both report non-syndromic HL. A 44.6 kb homozygous in-frame deletion spanning exons 6 to 33 of COL9A1 was detected via exome-based copy number variation analysis. The deleted exons were confirmed by PCR in the patient and his affected brother, who both have non-syndromic HL. Segregation analysis via qPCR confirmed the parents as heterozygous deletion carriers. Breakpoint analysis mapped the homozygous deletion spanning introns 5 to 33 (g.70,948,188_70,997,277del, NM_001851.4(COL9A1):c.697-3754_2112+769del, p.(Phe233_Ser704del), with an additional 67 bp of inserted intronic sequence that may have originated due to a fork stalling and template switching/microhomology-mediated break-induced replication (FoSTeS/MMBIR) mechanism. This mechanism has not been previously implicated in HL or STL. This is also the first reported copy number variation in COL9A1 that was identified through an exome data set in an Iranian family with apparent non-syndromic HL. The present study emphasizes the importance of exome-wide copy number variation analysis in molecular diagnosis and provides supporting evidence to associate COL9A1 with autosomal recessive non-syndromic HL.},

By sequencing five markers (ITS, LSU, TEF1α, RPB2, β-tubulin) from several fungal strains, we show that X. germanus cultivates the same two clones of A. grosmanniae in the USA and in Europe, whereas A. dispar is associated with a single A. hartigii clone across Europe. This low genetic diversity is consistent with predominantly asexual vertical transmission of Ambrosiella cultivars between beetle generations. This clonal agriculture is a remarkable case of convergence with fungus-farming ants, given that both groups have a completely different ecology and evolutionary history.},

  abstract  = {DNA damage response (DDR) involves dramatic transcriptional alterations, the mechanisms of which remain ill defined. Here, we show that following genotoxic stress, the RNA-binding motif protein 7 (RBM7) stimulates RNA polymerase II (Pol II) transcription and promotes cell viability by activating the positive transcription elongation factor b (P-TEFb) via its release from the inhibitory 7SK small nuclear ribonucleoprotein (7SK snRNP). This is mediated by activation of p38MAPK, which triggers enhanced binding of RBM7 with core subunits of 7SK snRNP. In turn, P-TEFb relocates to chromatin to induce transcription of short units, including key DDR genes and multiple classes of non-coding RNAs. Critically, interfering with the axis of RBM7 and P-TEFb provokes cellular hypersensitivity to DNA-damage-inducing agents due to activation of apoptosis. Our work uncovers the importance of stress-dependent stimulation of Pol II pause release, which enables a pro-survival transcriptional response that is crucial for cell fate upon genotoxic insult.},

Thus, our research aimed to investigate possible associations between global and regional myocardial T1 and T2 times and peak strain in patients with suspected myocarditis. From 2012 to 2015, 129 patients with clinically suspected myocarditis of the prospective, observational MyoRacer-Trial underwent systematic biventricular EMB at baseline and cardiac MRI at baseline and after three months as a follow-up. We divided the LV myocardium into 17 segments and estimated the segmental myocardial strain using FT. We registered T1 and T2 maps to the cine sequences and transferred the segmentations used for FT to ensure conformity of the myocardial segments. Multi-level multivariable linear mixed effects regression was applied to investigate the relation of segmental myocardial strain to relaxation times and their respective change from baseline to follow-up. We found a significant improvement in myocardial peak strain from baseline to follow-up (p < 0.001; all p-values given for likelihood ratio tests) and significant associations between higher T1 and T2 times and lower segmental myocardial peak strain (p ranging from < 0.001 to 0.049). E.g., regression coefficient (Reg. coef.) for segmental radial peak strain in short axis view (SRPS_SAX) and T1 time: -1.9, 95\% CI (-2.6;-1.2) \%/100 ms, p < 0.001. A decrease in T1 and T2 times from baseline to follow-up was also significantly related to a recovery of segmental peak strains (p ranging from < 0.001 to 0.050). E.g., Reg. coef. for SRPS_SAX per ΔT1: -1.8, 95\% CI (-2.5;-1.0) \%/100 ms, p < 0.001. Moreover, the higher the baseline T1 time, the more substantial the functional recovery from baseline to follow-up (p ranging from 0.004 to 0.042, e.g., for SRPS_SAX: Reg. coef. 1.3, 95\% CI (0.4;2.1) \%/100 ms, p 0.004). We did not find an effect modification by the presence of myocarditis in the EMB (p > 0.1). Our cross-sectional and longitudinal analyses provide evidence of dose-dependent correlations between T1 and T2 relaxation times and myocardial peak strain in patients with clinical presentation of myocarditis, regardless of the EMB result. Thus, assessing strain values and mapping relaxation times helps estimate the functional prognosis in patients with clinically suspected myocarditis.},

In proximitized materials, it is possible to realize properties that are not present in any constituent region of the considered heterostructure.

  abstract  = {The MYC oncoprotein binds to promoter-proximal regions of virtually all transcribed genes and enhances RNA polymerase II (Pol II) function, but its precise mode of action is poorly understood. Using mass spectrometry of both MYC and Pol II complexes, we show here that MYC controls the assembly of Pol II with a small set of transcription elongation factors that includes SPT5, a subunit of the elongation factor DSIF. MYC directly binds SPT5, recruits SPT5 to promoters, and enables the CDK7-dependent transfer of SPT5 onto Pol II. Consistent with known functions of SPT5, MYC is required for fast and processive transcription elongation. Intriguingly, the high levels of MYC that are expressed in tumors sequester SPT5 into non-functional complexes, thereby decreasing the expression of growth-suppressive genes. Altogether, these results argue that MYC controls the productive assembly of processive Pol II elongation complexes and provide insight into how oncogenic levels of MYC permit uncontrolled cellular growth.},

  abstract  = {The focus of this thesis is on analysing a linear stochastic partial differential equation (SPDE) with a bounded domain. The first part of the thesis commences with an examination of a one-dimensional SPDE. In this context, we construct estimators for the parameters of a parabolic SPDE based on discrete observations of a solution in time and space on a bounded domain. We establish central limit theorems for a high-frequency asymptotic regime, showing substantially smaller asymptotic variances compared to existing estimation methods. Moreover, asymptotic confidence intervals are directly feasible. Our approach builds upon realized volatilities and their asymptotic illustration as the response of a log-linear model with a spatial explanatory variable. This yields efficient estimators based on realized volatilities with optimal rates of convergence and minimal variances. We demonstrate our results by Monte Carlo simulations. Extending this framework, we analyse a second-order SPDE model in multiple space dimensions in the second part of this thesis and develop estimators for the parameters of this model based on discrete observations in time and space on a bounded domain. While parameter estimation for one and two spatial dimensions was established in recent literature, this is the first work that generalizes the theory to a general, multi-dimensional framework. Our methodology enables the construction of an oracle estimator for volatility within the underlying model. For proving central limit theorems, we use a high-frequency observation scheme. To showcase our results, we conduct a Monte Carlo simulation, highlighting the advantages of our novel approach in a multi-dimensional context.},

  abstract  = {Cognition refers to the ability to of animals to acquire, process, store and use vital information from the environment. Cognitive processes are necessary to predict the future and reduce the uncertainty of the ever-changing environment. Classically, research on animal cognition focuses on decisive cognitive tests to determine the capacity of a species by the testing the ability of a few individuals. This approach views variability between these tested key individuals as unwanted noise and is thus often neglected. However, inter-individual variability provides important insights to behavioral plasticity, cognitive specialization and brain modularity. Honey bees Apis mellifera are a robust and traditional model for the study of learning, memory and cognition due to their impressive capabilities and rich behavioral repertoire. In this thesis I have applied a novel view on the learning abilities of honey bees by looking explicitly at individual differences in a variety of learning tasks. Are some individual bees consistently smarter than some of her sisters? If so, will a smart individual always perform good independent of the time, the context and the cognitive requirements or do bees show distinct isolated 'cognitive modules'? My thesis presents the first comprehensive investigation of consistent individual differences in the cognitive abilities of honey bees. To speak of an individual as behaving consistently, a crucial step is to test the individual multiple times to examine the repeatability of a behavior. I show that free-flying bees remain consistent in a visual discrimination task for three consecutive days. Successively, I explored individual consistency in cognitive proficiency across tasks involving different sensory modalities, contexts and cognitive requirements. I found that free-flying bees show a cognitive specialization between visual and olfactory learning but remained consistent across a simple discrimination task and a complex concept learning task. I wished to further explore individual consistency with respect to tasks of different cognitive complexity, a question that has never been tackled before in an insect. I thus performed a series of four experiments using either visual or olfactory stimuli and a different training context (free-flying and restrained) and tested bees in a discrimination task, reversal learning and negative patterning. Intriguingly, across all these experiments I evidenced the same results: The bees' performances were consistent across the discrimination task and reversal learning and negative patterning respectively. No association was evidenced between reversal learning and negative patterning. After establishing the existence of consistent individual differences in the cognitive proficiency of honey bees I wished to determine factors which could underlie these differences. Since genetic components are known to underlie inter-individual variability in learning abilities, I studied the effects of genetics on consistency in cognitive proficiency by contrasting bees originating from either from a hive with a single patriline (low genetic diversity) or with multiple patrilines (high genetic diversity). These two groups of bees showed differences in the patterns of individually correlated performances, indicating a genetic component accounts for consistent cognitive individuality. Another major factor underlying variability in learning performances is the individual responsiveness to sucrose solution and to visual stimuli, as evidenced by many studies on restrained bees showing a positive correlation between responsiveness to task relevant stimuli and learning performances. I thus tested whether these relationships between sucrose/visual responsiveness and learning performances are applicable for free-flying bees. Free-flying bees were again subjected to reversal learning and negative patterning and subsequently tested in the laboratory for their responsiveness to sucrose and to light. There was no evidence of a positive relationship between sucrose/visual responsiveness and neither performances of free-flying bees in an elemental discrimination, reversal learning and negative patterning. These findings indicate that relationships established between responsiveness to task relevant stimuli and learning proficiency established in the laboratory with restrained bees might not hold true for a completely different behavioral context i.e. for free-flying bees in their natural environment. These results show that the honey bee is an excellent insect model to study consistency in cognitive proficiency and to identify the underlying factors. I mainly discuss the results with respect to the question of brain modularity in insects and the adaptive significance of individuality in cognitive abilities for honey bee colonies. I also provide a proposition of research questions which tie in this theme of consistent cognitive proficiency and could provide fruitful areas for future research.},

We demonstrate pervasive variation of these biophysical parameters with most changes occurring in mitosis and G1. Various cellular pathways and components vary in thermal stability, such as cell-cycle factors, polymerases, and chromatin remodelers. We demonstrate that protein thermal stability serves as a proxy for enzyme activity, DNA binding, and complex formation in situ. Strikingly, a large cohort of intrinsically disordered and mitotically phosphorylated proteins is stabilized and solubilized in mitosis, suggesting a fundamental remodeling of the biophysical environment of the mitotic cell. Our data represent a rich resource for cell, structural, and systems biologists interested in proteome regulation during biological transitions.},

  abstract  = {In contrast to classical theories of cognitive control, recent evidence suggests that cognitive control and unconscious automatic processing influence each other. First, masked semantic priming, an index of unconscious automatic processing, depends on attention to semantics induced by a previously executed task. Second, cognitive control operations (e.g., implementation of task sets indicating how to process a particular stimulus) can be activated by masked task cues, presented outside awareness. In this study, we combined both lines of research. We investigated in three experiments whether induction tasks and presentation of visible or masked task cues, which signal subsequent semantic or perceptual tasks but do not require induction task execution, comparably modulate masked semantic priming. In line with previous research, priming was consistently larger following execution of a semantic rather than a perceptual induction task. However, we observed in experiment 1 (masked letter cues) a reversed priming pattern following task cues (larger priming following cues signaling perceptual tasks) compared to induction tasks. Experiment 2 (visible letter cues) and experiment 3 (visible color cues) showed that this reversed priming pattern depended only on apriori associations between task cues and task elements (task set dominance), but neither on awareness nor on the verbal or non-verbal format of the cues. These results indicate that task cues have the power to modulate subsequent masked semantic priming through attentional mechanisms. Task-set dominance conceivably affects the time course of task set activation and inhibition in response to task cues and thus the direction of their modulatory effects on priming.},

Many viruses exploit the odorant system and enter the CNS via the olfactory bulb (OB). Upon intranasal vesicular stomatitis virus instillation, we show an accumulation of activated microglia and monocytes in the OB. Depletion of microglia during encephalitis results in enhanced virus spread and increased lethality. Activation, proliferation, and accumulation of microglia are regulated by type I IFN receptor signaling of neurons and astrocytes, but not of microglia. Morphological analysis of myeloid cells shows that type I IFN receptor signaling of neurons has a stronger impact on the activation of myeloid cells than of astrocytes. Thus, in the infected CNS, the cross talk among neurons, astrocytes, and microglia is critical for full microglia activation and protection from lethal encephalitis.},

To tackle the rapid and deeply connected dynamics characteristic of the Anthropocene, we argue for the inclusion of eco-evolutionary, novel ecosystem and social-ecological dynamics. These dynamics arise from adaptive responses in organisms and ecosystems to global environmental change and act at different integration levels and different time scales. We provide reasons and means to incorporate each improvement into aquatic ecosystem models. Throughout this study we refer to Lake Victoria as a microcosm of the evolving novel social-ecological systems of the Anthropocene. The Lake Victoria case clearly shows how interlinked eco-evolutionary, novel ecosystem and social-ecological dynamics are, and demonstrates the need for transdisciplinary research approaches towards global sustainability.},

We combined EGTA application and Ca2+-channel pharmacology in electrophysiological and two-photon Ca2+ imaging experiments with quantitative freeze-fracture immunoelectron microscopy and mathematical modeling. We found that a normally occurring developmental shift from release being dominated by Ca2+ influx through Cav2.1 and Cav2.2 channels with domain overlap and loose coupling (microdomains) to a nanodomain Cav2.1 to sensor coupling is impaired in Munc13-3-deficient synapses. Thus, at AZs lacking Munc13-3, release remained triggered by Cav2.1 and Cav2.2 microdomains, suggesting a critical role of Munc13-3 in the formation of release sites with calcium channel nanodomains.},

Whereas learning through the occurrence of punishment is well studied, much less is known about learning through its termination. Current research investigates how dopaminergic system function contributes to these processes in Drosophila, rats and humans.

  abstract  = {FKBP5 stellt im Stresssystem der HPA-Achse ein zentrales Gen bei der Regulation der Sensitivit{\"a}t des Glukokortikoidrezeptors und somit der Reaktion auf Stress dar. Zur Adaptation an Umwelteinfl{\"u}sse ist es selbst in ein komplexes System von Regulationsmechanismen eingebettet, die unter anderem epigenetische Modifikationen in Form von DNA-Methylierung umfassen. Bisherige Studien legen eine starke Assoziation von FKBP5 zu stressinduzierten psychischen Erkrankungen nahe und weisen auf eine Dysregulation der HPA-Achse als m{\"o}glichen Pathomechanismus hin. F{\"u}r die enge klinische Interaktion von Depression und Herzinsuffizienz sowie eine ebenfalls vermutete Rolle der HPA-Achse in der Pathogenese letzterer, k{\"o}nnte FKBP5 daher ein entscheidendes Bindeglied darstellen. Gleichzeitig bietet die Identifikation einer {\"u}ber FKBP5 ausgedr{\"u}ckten Dysregulation der HPA-Achse einen biologischen Befund, der als Marker f{\"u}r das Ansprechen einer antidepressiven Therapie herangezogen werden k{\"o}nnte. Ziel dieser Arbeit war daher die Untersuchung eines m{\"o}glichen Einflusses regulatorischer Parameter von FKBP5 auf die Herzinsuffizienz sowie eine Pr{\"u}fung dieser als m{\"o}gliche Biomarker f{\"u}r einen Erfolg der antidepressiven Therapie. Dazu wurden Blutproben von ProbandInnen der GEParD- bzw. DaCFail-Studie mit Depression, Herzinsuffizienz sowie gesunde Kontrollen untersucht. Durch Pyrosequenzierung bisulfitkonvertierter DNA erfolgte die Bestimmung der Methylierung regulatorischer CpGs. Die Messung der relativen mRNA-Expression erfolgte durch den Einsatz einer qPCR. In der Auswertung fand sich keine differentielle mRNA-Expression oder Methylierung zwischen den vier Untersuchungsgruppen. Allerdings reagierten depressive PatientInnen verglichen mit der Kontrollgruppe mit einer geringeren Zunahme der mRNA-Expression als Reaktion auf den mDST. Das Therapieansprechen in der Depressionsgruppe wiederum war mit einer niedrigeren Methylierung auf CpG7 sowie einer h{\"o}heren mRNA-Expression zu Therapiebeginn assoziiert. Im Behandlungsverlauf f{\"u}hrte eine Abnahme der mRNA-Expression bei den Respondern zu einer Ann{\"a}herung beider Gruppen. Diese Arbeit konnte keine Hinweise f{\"u}r eine Rolle von FKBP5 in der Pathogenese der Herzinsuffizienz finden. Allerdings zeigten die Befunde zur Regulation des Gens bei Glukokortikoidstimulation eine hohe Konstanz zu vorherigen Ergebnissen. In diesen Kontext reihen sich auch die Ergebnisse f{\"u}r das Therapieansprechen ein, die aufgrund einer Herabregulation der HPA-Achse im Therapieverlauf die Idee einer urs{\"a}chlichen HPA-Dysregulation in der Gruppe der Responder bekr{\"a}ftigen. F{\"u}r sich allein genommen lassen sich mRNA-Expression und Methylierung aufgrund mangelnder Sensitivit{\"a}t und Spezifit{\"a}t nicht als Biomarker f{\"u}r das Therapieansprechen einsetzen. Die bisherigen Befunde best{\"a}rken aber eine m{\"o}gliche Rolle in einer Batterie unterschiedlicher Biomarker auf verschiedenen Ebenen, wie Klinik, Psychometrie und Physiologie.},

  abstract  = {In der Pathogenese der Psoriasis spielen IL 17 und die Plastizit{\"a}t von Tregs zu Th17 Zellen mit Produktion proinflammatorischer Zytokine sowie die m{\"o}glicherweise reduzierte suppressive Funktion von Tregs eine entscheidende Rolle. Wir versuchten daher in unserer Arbeit einen {\"U}berblick {\"u}ber die T Zellverteilung im peripherem Blut bei PSO und HC zu erhalten und die Reaktion der Zellen auf IL 17, anti IL 17 und Secukinumab sowie ein Th 17 induzierendes Milieu im Vergleich von PSO und HC zu evaluieren. In der Analyse der PBMCs von PSO und HC konnten bei PSO tendenziell weniger inflammatorische Marker, wahrscheinlich aufgrund der niedrigen Krankheitsaktivit{\"a}t und der bereits eingeleiteten medikament{\"o}sen Therapie festgestellt werden. Nach Isolierung der Tregs und Kultivierung konnten bei PSO im Vergleich zu HC erh{\"o}hte inflammatorische Marker nachgewiesen werden. Dies kann an der h{\"o}heren Plastizit{\"a}t von Tregs bei PSO ex vivo ohne den Einfluss einer medikament{\"o}sen Therapie hin zu inflammatorischen Zellen. In den Suppressionsversuchen zeigte sich sowohl bei PSO als auch bei HC unter Th17 Milieu eine verminderte Inhibition der PBMCs durch die autologen Tregs. Urs{\"a}chlich hierf{\"u}r k{\"o}nnte eine Dysregulation der Tregs durch das Th17 Milieu oder eine Auswirkung des Th17-induzierenden Cocktails auf die PBMCs im Sinne einer Effektorresistenz gegen{\"u}ber den Tregs sein. Eine Ver{\"a}nderung der Suppression ergab sich f{\"u}r IL 17 oder anti IL 17 nicht. Unter der gleichzeitigen Kultivierung mit Secukinumab und einem Th17 induzierendem Cocktail konnte keine verbesserte Inhibition festgestellt werden. Insgesamt best{\"a}tigt die Arbeit eine Instabilit{\"a}t der Tregs bei PSO mit der M{\"o}glichkeit der Plastizit{\"a}t zu Th17 Zellen unter proinflammatorischem Milieu, sowie einen Verlust der Suppressionsf{\"a}higkeit durch eine Treg Dysfunktion oder eine erh{\"o}hte Effektorresistenz.

  abstract  = {Die Blut-Hirn-Schranke (BHS) stellt eine selektiv durchl{\"a}ssige Barriere dar, die den Austausch von Stoffen zwischen Blut und ZNS kontrolliert und so neuroprotektiv wirkt. Sie verhindert allerdings nicht nur die Passage toxischer Metaboliten, sondern verwehrt auch vielen therapeutischen Wirkstoffen den Zugang zum Gehirn. Die Forschung an Methoden zum Erreichen h{\"o}herer Arzneimittelkonzentrationen im Gehirn ist deshalb essenziell f{\"u}r die Behandlung zerebraler Erkrankungen wie dem zerebral metastasierten Mammakarzinom. Ziel dieser Arbeit war es deshalb, Wirkstoffe zu identifizieren, die die Permeabilit{\"a}t der BHS erh{\"o}hen. Die Substanzdatenbank LO1208 von Sigma-Aldrich wurde im Rahmen eines HTS auf ihre permeabilit{\"a}tsbeeinflussenden Eigenschaften untersucht. Hierbei konnten 31 Substanzen identifiziert werden, welche die Permeabilit{\"a}t von BLECs um mindestens 50 \% erh{\"o}hen. Aus diesen wurden 4-Amino-1,8-naphthalimid (PARP-Inhibitor) und GW2974 (TKI) f{\"u}r eine genauere Analyse ausgew{\"a}hlt. Als dritter Wirkstoff wurde Ibuilast (Inhibitor der PDE4, des MIF sowie des Toll-like-Rezeptor-4) untersucht, wobei dieser keine signifikante Ver{\"a}nderung der Permeabilit{\"a}t bewirkt. Die Messung des TEERs und der Permeabilit{\"a}t f{\"u}r Fluorescein best{\"a}tigten die Ergebnisse aus dem HTS, welches demnach zuk{\"u}nftig f{\"u}r Permeabilit{\"a}tstests eingesetzt werden kann. Die Zellviabilit{\"a}t wird durch 4 Amino-1,8-naphthalmid nicht beeinflusst. GW2974 und Ibudilast zeigen bei 500 µM einen toxischen Einfluss auf MCF-7-Zellen. BLECs werden durch 100 µM GW2974 gehemmt. Es konnte gezeigt werden, dass die erh{\"o}hte Permeabilit{\"a}t mit einer Ver{\"a}nderung der TJ-Proteinexpression einhergeht. 4-Amino-1,8-naphthalimid senkt die Expression von Occludin auf mRNA- und Proteinebene. GW2974 vermindert zus{\"a}tzlich die Expression von VE-Cadherin, Claudin-5 und ZO-1. Dar{\"u}ber hinaus wurde die Wirkung auf Effluxpumpen untersucht. Die Ergebnisse der mRNA- und Protein-expression weichen voneinander ab, weshalb eine genauere Untersuchung der Translationsvorg{\"a}nge sinnvoll erscheint. Glut-1 wird in GW2974 behandelten Zellen {\"u}berexprimiert, was auf eine erh{\"o}hte Aktivit{\"a}t der BLECs hinweist. GW2974 und 4-Amino-1,8-naphthalimid k{\"o}nnten durch ihre permeabilit{\"a}tssteigernde Wirkung die Ansprechrate einer systemischen Behandlung von PatientInnen mit einem zerebral metastasierten Mammakarzinom erh{\"o}hen und somit ihre Prognose verbessern. Detaillierte Studien zu Kombinationstherapien, den notwendigen Wirkstoff-konzentrationen und eventuellen negativen neurologischen Wirkungen sollten erwogen werden.},

  abstract  = {Die Erleichterung von einem k{\"o}rperlichen Schmerzreiz besitzt appetitiven Charakter (Leknes et al., 2008; 2011; Seymour et al., 2005), aktiviert belohnungsassoziierte Hirnstrukturen (Leknes et al., 2011; Leknes \& Brock, 2014; Leknes \& Tracey, 2008; Navratilova \& Porreca, 2014) und f{\"o}rdert durch ihre Konditionierbarkeit als Erleichterungslernen bezeichnete appetitive Lern- und Konditionierungsprozesse (Andreatta et al., 2010, 2012; 2013; 2017; Gerber et al., 2014; Tanimoto et al., 2004; Yarali et al., 2008). Die vorliegende Arbeit best{\"a}tigt das angewandte Versuchsparadigma als valides Modell f{\"u}r Erleichterungslernen im Menschen und zeigt erstmals, dass der appetitive Charakter von Schmerzerleichterung auch in Jugendlichen konditionierbar ist. Erfolgreiches Erleichterungslernen zeigte sich dabei in der untersuchten Stichprobe lediglich auf impliziter, nicht aber auf expliziter, kognitiver Ebene. Dies st{\"u}tzt Thesen und vorherige Forschungsbefunde einer Dualit{\"a}t assoziativen Lernens in ein implizites Lernen, welches vornehmlich subkortikale Strukturen erfordert und ein explizites Lernen, das vorrangig kortikale Strukturen wie den pr{\"a}frontalen Cortex involviert (Andreatta et al., 2010; Strack \& Deutsch, 2004; Williams et al., 2001). Die Beobachtungen einer differenten Furcht- versus Erleichterungs-Extinktion best{\"a}rken die Thesen eines diversen neuronalen Hintergrunds dieser beiden Lernformen (Diegelmann et al., 2013; Gerber et al., 2014; Yarali et al., 2009; Yarali \& Gerber, 2010). Gleichzeitig werfen die Studienergebnisse die Frage auf, ob und inwiefern im Erleichterungslernen von Jugendlichen Unterschiede zu jenem in Erwachsenen bestehen. Die Hypothese einer verst{\"a}rkten Akquisition von Erleichterungslernen bei Jugendlichen mit NSSV im Vergleich zu gesunden Jugendlichen ließ sich in der vorliegenden Studie nicht best{\"a}tigen. Somit liefern die Ergebnisse keinen direkten Hinweis darauf, dass ein verst{\"a}rktes Lernen durch Schmerzerleichterung an der {\"A}tiopathogenese von NSSV beteiligt sein k{\"o}nnte. Die vorliegende Arbeit zeigte vielmehr die Tendenz eines abgeschw{\"a}chten impliziten Erleichterungslernens bei den Jugendlichen mit NSSV. Die tendenziellen Gruppenunterschiede ließen sich nicht hinreichend durch eine differente aktuelle Stimmungslage oder durch eine unterschiedlich starke Auspr{\"a}gung aversiver emotionaler Anspannungen oder momentaner Angstaffekte erkl{\"a}ren. Innerhalb der Gruppe Jugendlicher mit NSSV zeigte sich auch kein Hinweis darauf, dass der Erfolg von Erleichterungslernen vom Schweregrad des NSSV oder von der aktuellen Einnahme von Antidepressiva abh{\"a}ngig sein k{\"o}nnte. Explorative Analysen ergaben, dass Gruppeneffekte in der vorliegenden Studie wom{\"o}glich aufgrund einer statistischen Untersch{\"a}tzung, bedingt durch einen zu geringen Stichprobenumfang, nicht das Signifikanzniveau erreichten und dass Unterschiede im Erleichterungslernen von Jugendlichen mit und ohne NSSV tats{\"a}chlich sogar noch st{\"a}rker ausgepr{\"a}gt sein k{\"o}nnten. Somit sollte die vorliegende Arbeit als Pilotstudie f{\"u}r zuk{\"u}nftige gr{\"o}ßer angelegte Studien zu Erleichterungslernen bei NSSV betrachtet werden. Zuk{\"u}nftige Studien erscheinen insbesondere sinnvoll mit Blick auf die hohe klinische sowie gesellschaftliche Relevanz von NSSV f{\"u}r welches, trotz der hohen Pr{\"a}valenzen und des deutlich erh{\"o}hten Morbidit{\"a}ts- und Mortalit{\"a}tsrisikos, zum aktuellen Zeitpunkt noch keine hinreichenden Erkl{\"a}rungsmodelle bestehen. Die Studie best{\"a}tigte das Vorliegen eines erh{\"o}hten Grades aversiver emotionaler Anspannung in Jugendlichen mit NSSV, welcher zuvor nur an Erwachsenen mit einer BPD untersucht und festgestellt worden war (Niedtfeld et al., 2010; Stiglmayr et al., 2005). Die Abnahme negativer Affekte bei den Jugendlichen mit NSSV im Studienverlauf repliziert die Ergebnisse vorheriger Studien, in denen eine Reduktion selbst-berichteter negativer Affekte durch die Beendigung eines Schmerzreizes beobachtet wurde (Bresin et al., 2010; Bresin \& Gordon, 2013). Damit best{\"a}rken die Studienergebnisse bestehende Erkl{\"a}rungsmodelle f{\"u}r NSSV, welche eine entscheidende Beteiligung der k{\"o}rperlichen Schmerzen und der Schmerzerleichterung bei der Selbstverletzung an der Affektregulation vermuten. Weiterhin wirft die vorliegende Arbeit die Frage auf, welche Rolle eine ver{\"a}nderte Wahrnehmung von Schmerz und Schmerzerleichterung in der {\"A}tiopathogenese von NSSV einnimmt und wie diese sich auf Lernprozesse auswirkt. Insgesamt erbr{\"a}chten weitere Erkenntnisse {\"u}ber den potenziellen Zusammenhang von NSSV und abweichendem Erleichterungslernen ein besseres Verst{\"a}ndnis f{\"u}r Mechanismen der Entstehung und Aufrechterhaltung von NSSV und b{\"o}ten zudem m{\"o}glicherweise Ans{\"a}tze f{\"u}r neue Therapiem{\"o}glichkeiten des St{\"o}rungsbildes.},

  abstract  = {p97 uses the energy of ATP hydrolysis to unfold and thereby segregate proteins. It is involved in various cellular processes such as proteasomal degradation, DNA damage repair, autophagy, and endo-lysosomal trafficking. The specificity for these processes is controlled by more than 30 regulatory cofactors. Interactions of p97 with cofactors and target proteins are known to be highly dynamic and transient. To identify new interaction partners and to uncover novel cellular functions of p97, the interactome of endogenous p97 was determined by using in cellulo crosslinking followed by immunoprecipitation and mass spectrometry. Myoferlin (MYOF) was identified as a novel interactor of p97 and the interaction was validated in reciprocal immunoprecipitation experiments for different cell lines. The ferlin family member MYOF is a tail-anchored membrane protein containing multiple C2 domains. MYOF is involved in various membrane repair and trafficking processes such as the endocytic recycling of cell surface receptors. The MYOF interactome was determined by mass spectrometry. Among others, the p97 cofactor PLAA, CD71 and Rab14 were identified as common interactors of p97 and MYOF. Immunoprecipitation experiments with PLAA KO cells revealed that the interaction between MYOF and p97 depends on PLAA. Immunofluorescence microscopy showed a co-localization of MYOF with Rab14 and Rab11, which are both involved in endocytic recycling pathways. Furthermore, immunofluoroscence experiments revealed that MYOF and the p97 cofactor PLAA are localized to Rab14- and Rab5-positive endosomal compartments. Using p97 inhibitors and p97 trapping mutants, the presence of p97 at MYOF-positive and Rab14-positive structures could be demonstrated. Consistent with this finding, the endocytic recycling of transferrin was delayed upon inhibition of p97. Taken together, this work identified MYOF as a novel interactor of p97 and suggests a role for p97 in the recycling of endocytic cargo.},

Mithilfe des Lautanalyseprogramms CDAP wurden f{\"u}r die vorliegende Arbeit 4686 fr{\"u}hkindliche Lautaufahmen bez{\"u}glich ihres Melodiekonturverlaufs sowie ihrer auditiv und visuell wahrnehmbaren Feinstrukturmerkmale detailliert analysiert und ausgewertet. Der Datensatz spiegelt repr{\"a}sentativ das typische Lautrepertoire von S{\"a}uglingen im zweiten Lebenshalbjahr mit den hier untersuchten Komfort-Vokalisationstypen wider: {\"U}bergangslaute, marginale und kanonische Babbellaute. In {\"U}bereinstimmung mit dem von Wermke und Mende postulierten MD-Modell, das eine vokalisationstyp-{\"u}bergreifende Komplexit{\"a}tszunahme fr{\"u}hkindlicher Laut{\"a}ußerungen beschreibt, konnten erstmals die regelhaften Entwicklungsverl{\"a}ufe im zweiten Lebenshalbjahr gezeigt und ausf{\"u}hrlich benannt werden. Dabei scheint die Zunahme der Komplexit{\"a}t vor allem im Zusammenhang mit artikulatorischen Reifeprozessen zu stehen. In der Melodie selbst fiel diesbez{\"u}glich vor allem der Einbau von Segmentierungen auf.

  abstract  = {Expanding on a general equilibrium model of offshoring, we analyze the effects of a unilateral emissions tax increase on the environment, income, and inequality. Heterogeneous firms allocate labor across production tasks and emissions abatement, while only the most productive can benefit from lower labor and/or emissions costs abroad and offshore. We find a non-monotonic effect on global emissions, which decline if the initial difference in emissions taxes is small. For a sufficiently large difference, global emissions rise, implying emissions leakage of more than 100\%. The underlying driver is a global technique effect: While the emissions intensity of incumbent non-offshoring firms declines, the cleanest firms start offshoring. Moreover, offshoring firms become dirtier, induced by a reduction in the foreign effective emissions tax in general equilibrium. Implementing a BCA prevents emissions leakage, reduces income inequality in the reforming country, but raises inequality across countries.},

  abstract  = {Objectives Glycemic control by medical treatment represents one therapeutic strategy for diabetic patients. The Na+-d-glucose cotransporter 1 (SGLT1) is currently of high interest in this context. SGLT1 is known to mediate glucose absorption and incretin secretion in the small intestine. Recently, inhibition of SGLT1 function was shown to improve postprandial hyperglycemia. In view of the lately demonstrated SGLT1 expression in pancreatic islets, we investigated if loss of SGLT1 affects islet morphology and function. Methods Effects associated with the loss of SGLT1 on pancreatic islet (cyto) morphology and function were investigated by analyzing islets of a SGLT1 knockout mouse model, that were fed a glucose-deficient, fat-enriched diet (SGLT1-/--GDFE) to circumvent the glucose-galactose malabsorption syndrome. To distinguish diet- and Sglt1-/--dependent effects, wildtype mice on either standard chow (WT-SC) or the glucose-free, fat-enriched diet (WT-GDFE) were used as controls. Feeding a glucose-deficient, fat-enriched diet further required the analysis of intestinal SGLT1 expression and function under diet-conditions. Results Consistent with literature, our data provide evidence that small intestinal SGLT1 mRNA expression and function is regulated by nutrition. In contrast, pancreatic SGLT1 mRNA levels were not affected by the applied diet, suggesting different regulatory mechanisms for SGLT1 in diverse tissues. Morphological changes such as increased islet sizes and cell numbers associated with changes in proliferation and apoptosis and alterations of the β- and α-cell population are specifically observed for pancreatic islets of SGLT1-/--GDFE mice. Glucose stimulation revealed no insulin response in SGLT1-/--GDFE mice while WT-GDFE mice displayed only a minor increase of blood insulin. Irregular glucagon responses were observed for both, SGLT1-/--GDFE and WT-GDFE mice. Further, both animal groups showed a sustained release of GLP-1 compared to WT-SC controls. Conclusion Loss or impairment of SGLT1 results in abnormal pancreatic islet (cyto)morphology and disturbed islet function regarding the insulin or glucagon release capacity from β- or α-cells, respectively. Consequently, our findings propose a new, additional role for SGLT1 maintaining proper islet structure and function.},

  abstract  = {The prevalence of germ line mutations in non-BRCA1/2 genes associated with hereditary breast cancer (BC) is low, and the role of some of these genes in BC predisposition and pathogenesis is conflicting. In this study, 5589 consecutive BC index patients negative for pathogenic BRCA1/2 mutations and 2189 female controls were screened for germ line mutations in eight cancer predisposition genes (ATM, CDH1, CHEK2, NBN, PALB2, RAD51C, RAD51D, and TP53). All patients met the inclusion criteria of the German Consortium for Hereditary Breast and Ovarian Cancer for germ line testing. The highest mutation prevalence was observed in the CHEK2 gene (2.5\%), followed by ATM (1.5\%) and PALB2 (1.2\%). The mutation prevalence in each of the remaining genes was 0.3\% or lower. Using Exome Aggregation Consortium control data, we confirm significant associations of heterozygous germ line mutations with BC for ATM (OR: 3.63, 95\%CI: 2.67-4.94), CDH1 (OR: 17.04, 95\%CI: 3.54-82), CHEK2 (OR: 2.93, 95\%CI: 2.29-3.75), PALB2 (OR: 9.53, 95\%CI: 6.25-14.51), and TP53 (OR: 7.30, 95\%CI: 1.22-43.68). NBN germ line mutations were not significantly associated with BC risk (OR:1.39, 95\%CI: 0.73-2.64). Due to their low mutation prevalence, the RAD51C and RAD51D genes require further investigation. Compared with control datasets, predicted damaging rare missense variants were significantly more prevalent in CHEK2 and TP53 in BC index patients. Compared with the overall sample, only TP53 mutation carriers show a significantly younger age at first BC diagnosis. We demonstrate a significant association of deleterious variants in the CHEK2, PALB2, and TP53 genes with bilateral BC. Both, ATM and CHEK2, were negatively associated with triple-negative breast cancer (TNBC) and estrogen receptor (ER)-negative tumor phenotypes.

  abstract  = {The development of alternatives to vascular bone grafts, the current clinical standard for the surgical repair of large segmental bone defects still today represents an unmet medical need. The subcutaneous formation of transplantable bone has been successfully achieved in scaffolds axially perfused by an arteriovenous loop (AVL) and seeded with bone marrow stromal cells or loaded with inductive proteins. Although demonstrating clinical potential, AVL-based approaches involve complex microsurgical techniques and thus are not in widespread use. In this study, 3D-printed microporous bioceramics, loaded with autologous total bone marrow obtained by needle aspiration, are placed around and next to an unoperated femoral vein for 8 weeks to assess the effect of a central flow-through vein on bone formation from marrow in a subcutaneous site. A greater volume of new bone tissue is observed in scaffolds perfused by a central vein compared with the nonperfused negative control. These analyses are confirmed and supplemented by calcified and decalcified histology. This is highly significant as it indicates that transplantable vascularized bone can be grown using dispensable vein and marrow tissue only. This is the first report illustrating the capacity of an intrinsic vascularization by a single vein to support ectopic bone formation from untreated marrow.},

  abstract  = {Introduction Stimulation settings of deep brain stimulation (DBS) have evolved empirically within a limited parameter space dictated by first generation devices. There is a need for controlled clinical studies, which evaluate efficacy and safety of established programming practice against novel programming options provided by modern neurostimulation devices. Methods Here, we tested a polarity reversal from conventional monopolar cathodic to anodic stimulation in an acute double-blind, randomized, cross-over study in patients with PD implanted with bilateral STN DBS. The primary outcome measure was the difference between efficacy and side-effect thresholds (current amplitude, mA) in a monopolar review and the severity of motor symptoms (as assessed by MDS-UPDRS III ratings) after 30 min of continuous stimulation in the medication off-state. Results Effect and side effect thresholds were significantly higher with anodic compared to cathodic stimulation (3.36 ± 1.58 mA vs. 1.99 ± 1.37 mA; 6.05 ± 1.52 mA vs. 4.15 ± 1.13 mA; both p < 0.0001). However, using a predefined amplitude of 0.5 mA below the respective adverse effect threshold, blinded MDS-UPDRS-III-ratings were significantly lower with anodic stimulation (anodic: median 17 [min: 12, max: 25]; cathodic: 23 [12, 37]; p < 0.005). Conclusion Effective anodic stimulation requires a higher charge injection into the tissue, but may provide a better reduction of off-period motor symptoms within the individual therapeutic window. Therefore, a programming change to anodic stimulation may be considered in patients suffering from residual off-period motor symptoms of PD despite reaching the adverse effect threshold of cathodic stimulation in the subthalamic nucleus.},

Methods In this institutional review board approved prospective study 13 patients with spontaneous AINS were examined at 3 Tesla including a transversal T2-weighted turbo-spin-echo and a spin-echo echo-planar-imaging pulse sequence of the upper arm level. Calculations of quantitative DTI parameters including fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) for median nerve lesion and non-lesion fascicles as well as ulnar and radial nerve were obtained. DTI values were compared to each other and to a previously published dataset of 58 healthy controls using one-way Analysis of Variance with Bonferroni correction and p-values <.05 were considered significant. Receiver operating characteristic (ROC) curves were performed to assess diagnostic accuracy. Results FA of median nerve lesion fascicles was decreased compared to median nerve non-lesion fascicles, ulnar nerve and radial nerve while MD, RD, and AD was increased (p < .001 for all parameters). Compared to median nerve values of healthy controls, lesion fascicles showed a significant decrease in FA while MD, RD, and AD was increased (p < .001 for all parameters). FA of median nerve non-lesion fascicles showed a weak significant decrease compared to healthy controls (p < .01) while there was no difference in MD, RD, and AD. ROC analyses revealed an excellent diagnostic accuracy of FA, MD and RD in the discrimination of median nerve lesion and non-lesion fascicles in AINS patients as well as in the discrimination of lesion fascicles and normative median nerve values of healthy controls. Conclusion By applying this functional MR Neurography technique in patients with AINS, this proof of principle study demonstrates that diffusion tensor imaging is feasible to quantify structural nerve injury at the anatomical level of individual fascicles.},

Prototype foamy virus (PFV) vectors have been described for gene therapy, although their use has mainly been restricted to ex vivo stem cell modification. Here we report direct in vivo transgene delivery with PFV vectors carrying reporter gene constructs. In our investigations, systemic PFV vector delivery to neonatal mice gave transgene expression in the heart, xiphisternum, liver, pancreas, and gut, whereas intracranial administration produced brain expression until animals were euthanized 49 days post-transduction. Immunostaining and confocal microscopy analysis of injected brains showed that transgene expression was highly localized to hippocampal architecture despite vector delivery being administered to the lateral ventricle. This was compared with intracranial biodistribution of lentiviral vectors and adeno-associated virus vectors, which gave a broad, non-specific spread through the neonatal mouse brain without regional localization, even when administered at lower copy numbers. Our work demonstrates that PFV can be used for neonatal gene delivery with an intracranial expression profile that localizes to hippocampal neurons, potentially because of the mitotic status of the targeted cells, which could be of use for research applications and gene therapy of neurological disorders.},

  abstract  = {Objective Plasminogen activator inhibitor-1 (PAI-1) is the key endogenous inhibitor of fibrinolysis, and enhances clot formation after injury. In traumatic brain injury, dysregulation of fibrinolysis may lead to sustained microthrombosis and accelerated lesion expansion. In the present study, we hypothesized that PAI-1 mediates post-traumatic malfunction of coagulation, with inhibition or genetic depletion of PAI-1 attenuating clot formation and lesion expansion after brain trauma. Methods We evaluated PAI-1 as a possible new target in a mouse controlled cortical impact (CCI) model of traumatic brain injury. We performed the pharmacological inhibition of PAI-1 with PAI-039 and stimulation by tranexamic acid, and we confirmed our results in PAI-1-deficient animals. Results PAI-1 mRNA was time-dependently upregulated, with a 305-fold peak 12 hours after CCI, which effectively counteracted the 2- to 3-fold increase in cerebral tissue-type/urokinase plasminogen activator expression. PAI-039 reduced brain lesion volume by 26\% at 24 hours and 43\% at 5 days after insult. This treatment also attenuated neuronal apoptosis and improved neurofunctional outcome. Moreover, intravital microscopy demonstrated reduced post-traumatic thrombus formation in the pericontusional cortical microvasculature. In PAI-1-deficient mice, the therapeutic effect of PAI-039 was absent. These mice also displayed 13\% reduced brain damage compared with wild type. In contrast, inhibition of fibrinolysis with tranexamic acid increased lesion volume by 25\% compared with vehicle. Interpretation This study identifies impaired fibrinolysis as a critical process in post-traumatic secondary brain damage and suggests that PAI-1 may be a central endogenous inhibitor of the fibrinolytic pathway, promoting a procoagulatory state and clot formation in the cerebral microvasculature.

  abstract  = {Anticipation of potentially threatening social situations is a key process in social anxiety disorder (SAD). In other anxiety disorders, recent research of neural correlates of anticipation of temporally unpredictable threat suggests a temporally dissociable involvement of amygdala and bed nucleus of the stria terminalis (BNST) with phasic amygdala responses and sustained BNST activation. However, the temporal profile of amygdala and BNST responses during temporal unpredictability of threat has not been investigated in patients suffering from SAD. We used functional magnetic resonance imaging (fMRI) to investigate neural activation in the central nucleus of the amygdala (CeA) and the BNST during anticipation of temporally unpredictable aversive (video camera observation) relative to neutral (no camera observation) events in SAD patients compared to healthy controls (HC). For the analysis of fMRI data, we applied two regressors (phasic/sustained) within the same model to detect temporally dissociable brain responses. The aversive condition induced increased anxiety in patients compared to HC. SAD patients compared to HC showed increased phasic activation in the CeA and the BNST for anticipation of aversive relative to neutral events. SAD patients as well as HC showed sustained activity alterations in the BNST for aversive relative to neutral anticipation. No differential activity during sustained threat anticipation in SAD patients compared to HC was found. Taken together, our study reveals both CeA and BNST involvement during threat anticipation in SAD patients. The present results point towards potentially SAD-specific threat processing marked by elevated phasic but not sustained CeA and BNST responses when compared to HC.},

MtDNA was quantified in whole blood using a plasmid-normalized PCR-based assay. At baseline, 1235 patients had prevalent cardiovascular disease. These patients had a significantly lower mtDNA copy number than patients without cardiovascular disease (fully-adjusted model: odds ratio 1.03, 95\% confidence interval [CI] 1.01-1.05 per 10 mtDNA copies decrease). After four years of follow-up, we observed a significant inverse association between mtDNA copy number and all-cause mortality, adjusted for kidney function and cardiovascular disease risk factors (hazard ratio 1.37, 95\% CI 1.09-1.73 for quartile 1 compared to quartiles 2-4). When grouped by causes of death, estimates pointed in the same direction for all causes but in a fully-adjusted model decreased copy numbers were significantly lower only in infection-related death (hazard ratio 1.82, 95\% CI 1.08-3.08). A similar association was observed for hospitalizations due to infections in 644 patients (hazard ratio 1.19, 95\% CI 1.00-1.42 in the fully-adjusted model). Thus, our data support a role of mitochondrial dysfunction in increased cardiovascular disease and mortality risks as well as susceptibility to infections in patients with CKD.},

Previous studies have shown that emotional self-referential processing is related to structure and function of cortical midline areas such as medial prefrontal cortex (mPFC), and that it can be altered on a behavioral level by specific mental training practices. However, it remains unknown how behavioral training-related change in emotional self-concept content relates to structural plasticity. Methods To address this issue, we examined the relationship between training-induced change in participant's emotional self-concept measured through emotional word use in the Twenty Statement Test and change in cortical thickness in the context of a large-scale longitudinal mental training study called the ReSource Project. Results Based on prior behavioral findings showing increased emotional word use particularly after socio-cognitive training targeting perspective-taking capacities, this study extended these results by revealing that individual differences in the degree to which participants changed their emotional self-concept after training was positively related to cortical thickness change in right mPFC extending to dorsolateral PFC (dlPFC). Furthermore, increased self-related negative emotional word use after training was positively associated with cortical thickness change in left pars orbitalis and bilateral dlPFC. Conclusions Our findings reveal training-related structural brain change in regions known to be involved in self-referential processing and cognitive control, and could indicate a relationship between restructuring of the emotional self-concept content as well as reappraisal of negative aspects and cortical thickness change. As such, our findings can guide the development of psychological interventions targeted to alter specific facets of the self-concept.},

  abstract  = {Objective Cadherin-13 (CDH13), a member of the calcium-dependent cell adhesion molecule family, has been linked to neurodevelopmental disorders, including autism spectrum (ASD) and attention-deficit/hyperactivity (ADHD) disorders, but also to depression. In the adult brain, CDH13 expression is restricted e.g. to the presynaptic compartment of inhibitory GABAergic synapses in the hippocampus and Cdh13 knockout mice show an increased inhibitory drive onto hippocampal CA1 pyramidal neurons, leading to a shift in excitatory/inhibitory balance. CDH13 is also moderating migration of serotonergic neurons in the dorsal raphe nucleus, establishing projections preferentially to the thalamus and cerebellum during brain development. Furthermore, CDH13 is upregulated by chronic stress as well as in depression, suggesting a role in early-life adaptation to stressful experience. Here, we therefore investigated the interaction between Cdh13 variation and neonatal maternal separation (MS) in mice. Methods Male and female wild-type (Cdh13+/+), heterozygous (Cdh13+/-) and homozygous (Cdh13-/-) knockout mice exposed to MS, or daily handling as control, were subjected to a battery of behavioural tests to assess motor activity, learning and memory as well as anxiety-like behaviour. A transcriptome analysis of the hippocampus was performed in an independent cohort of mice which was exposed to MS or handling, but remained na{\"i}ve for behavioural testing. Results MS lead to increased anxiety-like behaviour in Cdh13-/- mice compared to the other two MS groups. Cdh13-/- mice showed a context-dependent effect on stress- and anxiety-related behaviour, impaired extinction learning following contextual fear conditioning and decreased impulsivity, as well as a mild decrease in errors in the Barnes maze and reduced risk-taking in the light-dark transition test after MS. We also show sex differences, with increased locomotor activity in female Cdh13-/- mice, but unaltered impulsivity and activity in male Cdh13-/- mice. Transcriptome analysis revealed several pathways associated with cell surface/adhesion molecules to be altered following Cdh13 deficiency, together with an influence on endoplasmic reticulum function. Conclusion MS resulted in increased stress resilience, increased exploration and an overall anxiolytic behavioural phenotype in male Cdh13+/+ and Cdh13+/- mice. Cdh13 deficiency, however, obliterated most of the effects caused by early-life stress, with Cdh13-/- mice exhibiting delayed habituation, no reduction of anxiety-like behaviour and decreased fear extinction. Our behavioural findings indicate a role of CDH13 in the programming of and adaptation to early-life stress. Finally, our transcriptomic data support the view of CDH13 as a neuroprotective factor as well as a mediator in cell-cell interactions, with an impact on synaptic plasticity.},

In parallel, accompanying ramp-up mechanisms are increasingly coming into focus with the first ones already being released. However, these proposals usually translate mechanisms from renewable energy (RE) policy without considering the specific uncertainties, spillovers, and externalities of integrating hydrogen electrolysis into electricity grids. This article details how different aspects of a policy can address the specific issues, namely funding, risk-mitigation, and the complex relation with electricity markets. It shows that, compared to RE policy, subsidies need to emphasize the input side more strongly as price risks and intermittency from electricity markets are more prominent than from hydrogen markets. Also, it proposes a targeted mechanism to capture the positive externality of mitigating excess electricity in the grid while keeping investment security high. Economic policy should consider such approaches before massively scaling support and avoid the design shortcomings experienced with early RE policy.},

  abstract  = {With 37 million inhabitants, Tokyo is the world's largest city in UN statistics. With this work we call this ranking into question. Usually, global city rankings are based on nationally collected population figures, which rely on administrative units. Sprawling urban growth, however, leads to morphological city extents that may surpass conventional administrative units. In order to detect spatial discrepancies between the physical and the administrative city, we present a methodology for delimiting Morphological Urban Areas (MUAs). We understand MUAs as a territorially contiguous settlement area that can be distinguished from low-density peripheral and rural hinterlands. We design a settlement index composed of three indicators (settlement area, settlement area proportion and density within the settlements) describing a gradient of built-up density from the urban center to the periphery applying a sectoral monocentric city model. We assume that the urban-rural transition can be defined along this gradient. With it, we re-territorialize the conventional administrative units. Our data basis are recent mapping products derived from multi-sensoral Earth observation (EO) data - namely the Global Urban Footprint (GUF) and the GUF Density (GUF-DenS) - providing globally consistent knowledge about settlement locations and densities. For the re-territorialized MUAs we calculate population numbers using WorldPop data. Overall, we cover the 1692 cities with >300,000 inhabitants on our planet. In our results we compare the consistently re-territorialized MUAs and the administrative units as well as their related population figures. We find the MUA in the Pearl River Delta the largest morphologically contiguous urban agglomeration in the world with a calculated population of 42.6 million. Tokyo, in this new list ranked number 2, loses its top position. In rank-size distributions we present the resulting deviations from previous city rankings. Although many MUAs outperform administrative units by area, we find that, contrary to what we assumed, in most cases MUAs are considerably smaller than administrative units. Only in Europe we find MUAs largely outweighing administrative units in extent.},

  abstract  = {Background Enzyme replacement therapy (ERT) with recombinant human α-galactosidase has been available for the treatment of Fabry disease since 2001 in Europe and 2003 in the USA. Treatment outcomes with ERT are dependent on baseline patient characteristics, and published data are derived from heterogeneous study populations. Methods We conducted a comprehensive systematic literature review of all original articles on ERT in the treatment of Fabry disease published up until January 2017. This article presents the findings in adult male patients. Results Clinical evidence for the efficacy of ERT in adult male patients was available from 166 publications including 36 clinical trial publications. ERT significantly decreases globotriaosylceramide levels in plasma, urine, and in different kidney, heart, and skin cell types, slows the decline in estimated glomerular filtration rate, and reduces/stabilizes left ventricular mass and cardiac wall thickness. ERT also improves nervous system, gastrointestinal, pain, and quality of life outcomes. Conclusions ERT is a disease-specific treatment for patients with Fabry disease that may provide clinical benefits on several outcomes and organ systems. Better outcomes may be observed when treatment is started at an early age prior to the development of organ damage such as chronic kidney disease or cardiac fibrosis. Consolidated evidence suggests a dose effect. Data described in male patients, together with female and paediatric data, informs clinical practice and therapeutic goals for individualized treatment.},

  abstract  = {To study delayed genetic and epigenetic radiation effects, which may trigger radiation-induced carcinogenesis, we have established single-cell clones from irradiated and non-irradiated primary human fibroblasts. Stable clones were endowed with the same karyotype in all analyzed metaphases after 20 population doublings (PDs), whereas unstable clones displayed mosaics of normal and abnormal karyotypes. To account for variation in radiation sensitivity, all experiments were performed with two different fibroblast strains. After a single X-ray dose of 2 Gy more than half of the irradiated clones exhibited radiation-induced genome instability (RIGI). Irradiated clones displayed an increased rate of loss of chromosome Y (LOY) and copy number variations (CNVs), compared to controls. CNV breakpoints clustered in specific chromosome regions, in particular 3p14.2 and 7q11.21, coinciding with common fragile sites. CNVs affecting the FHIT gene in FRA3B were observed in independent unstable clones and may drive RIGI. Bisulfite pyrosequencing of control clones and the respective primary culture revealed global hypomethylation of ALU, LINE-1, and alpha-satellite repeats as well as rDNA hypermethylation during in vitro ageing. Irradiated clones showed further reduced ALU and alpha-satellite methylation and increased rDNA methylation, compared to controls. Methylation arrays identified several hundred differentially methylated genes and several enriched pathways associated with in vitro ageing. Methylation changes in 259 genes and the MAP kinase signaling pathway were associated with delayed radiation effects (after 20 PDs). Collectively, our results suggest that both genetic (LOY and CNVs) and epigenetic changes occur in the progeny of exposed cells that were not damaged directly by irradiation, likely contributing to radiation-induced carcinogenesis. We did not observe epigenetic differences between stable and unstable irradiated clones. The fact that the DNA methylation (DNAm) age of clones derived from the same primary culture varied greatly suggests that DNAm age of a single cell (represented by a clone) can be quite different from the DNAm age of a tissue. We propose that DNAm age reflects the emergent property of a large number of individual cells whose respective DNAm ages can be highly variable.},

This paper presents the findings of a systematic literature review of treatment outcomes with ERT in adult female patients. Methods A comprehensive systematic literature review was conducted through January 2017 to retrieve published papers with original data on ERT in the treatment of Fabry disease. The review included all original articles that presented ERT outcomes data on patients with Fabry disease, irrespective of the study type. Results Clinical evidence for the efficacy of ERT in female patients was available from 67 publications including six clinical trial publications, and indicates significant reductions in plasma and urine globotriaosylceramide (GL-3) accumulation (in female patients with elevated pre-treatment levels) and improvements in cardiac parameters and quality of life (QoL). To date, data are insufficient to conclude on the effects of ERT on the nervous system, gastrointestinal manifestations, and pain in female patients with Fabry disease. Conclusions This review of available literature data demonstrates that ERT in adult female patients with Fabry disease has a beneficial effect on GL-3 levels and cardiac outcomes. The current evidence also suggests that ERT may improve QoL in this patient population, though further studies are needed to examine these results.},

  abstract  = {Background Infants with history of prematurity (<37 weeks gestation) and low birth weight (LBW, <2500 g) are at high risk of infection due to functional immaturity of normal physical and immunological defense mechanisms. Despite current recommendations that infants with history of prematurity/LBW should receive routine immunization according to the same schedule and chronological age as full-term infants, immunization is often delayed. Methods Here we summarize 10 clinical studies and 15 years of post-marketing safety surveillance of GSK's hexavalent vaccine (DTPa-HBV-IPV/Hib), a combined diphtheria-tetanus-acellular-pertussis-hepatitis-B-inactivated-poliovirus-Haemophilus influenzae-type-b (Hib) conjugate vaccine, when administered alone, or co-administered with pneumococcal conjugate, rotavirus, and meningococcal vaccines and respiratory syncytial virus IgG to infants with history of prematurity/LBW in clinical trials. Results At least 92.5\% of infants with history of prematurity/LBW as young as 24 weeks gestation in clinical studies were seropositive to all vaccine antigens after 3-dose primary vaccination with GSK's hexavalent DTPa-HBV-IPV/Hib vaccine, with robust immune responses to booster vaccination. Seropositivity rates and antibody concentrations to hepatitis B and Hib appeared lower in infants with history of prematurity/LBW than term infants. Between 13-30\% of medically stable infants with history of prematurity developed apnea after vaccination with GSK's hexavalent DTPa-HBV-IPV/Hib vaccine; usually after dose 1. The occurrence of post-immunization cardiorespiratory events appears to be influenced by the severity of any underlying neonatal condition. Most cardiorespiratory events resolve spontaneously or require minimal intervention. GSK's hexavalent DTPa-HBV-IPV/Hib vaccine was well tolerated in co-administration regimens. Conclusion GSK's hexavalent DTPa-HBV-IPV/Hib vaccine alone or co-administered with other pediatric vaccines has a clinically acceptable safety and immunogenicity profile when used in infants with history of prematurity/LBW for primary and booster vaccination. Additional studies are needed in very premature and very LBW infants. However, currently available data support using GSK's hexavalent DTPa-HBV-IPV/Hib vaccine to immunize infants with history of prematurity/LBW according to chronological age.},

  abstract  = {Background Fabry disease is caused by a deficiency of the lysosomal enzyme α-galactosidase, resulting in progressive accumulation of globotriaosylceramide (GL-3). The disease can manifest early during childhood and adolescence. Enzyme replacement therapy (ERT) with recombinant human α-galactosidase is the first specific treatment for Fabry disease and has been available in Europe since 2001. This paper presents the findings of a systematic literature review of clinical outcomes with ERT in paediatric patients with Fabry disease. Methods A comprehensive systematic review of published literature on ERT in Fabry disease was conducted in January 2017. The literature analysis included all original articles reporting outcomes of ERT in paediatric patients. Results Treatment-related outcomes in the paediatric population were reported in six publications derived from open-label clinical trials and in 10 publications derived from observational or registry-based studies. ERT was shown to significantly reduce plasma and urine GL-3 levels in paediatric patients with Fabry disease. The effect of ERT on GL-3 clearance from renal podocytes appeared to be agalsidase dose-dependent. ERT relieved pain and improved gastrointestinal symptoms and quality of life. Conclusions Based on the published literature, the use of ERT in paediatric patients can significantly clear GL-3 accumulation, ameliorate the early symptoms of Fabry disease, and improve quality of life. Treatment with ERT in paediatric patients with Fabry disease may be important to prevent further disease progression and overt organ damage.},

  abstract  = {Enhancement of synaptic plasticity through changes in neuronal gene expression is a prerequisite for improved cognitive performance. Moreover, several studies have shown that DNA methylation is able to affect the expression of (e.g. plasticity) genes that are important for several cognitive functions. In this study, the effect of the DNA methyltransferase (DNMT) inhibitor RG108 was assessed on object pattern separation (OPS) task in mice. In addition, its effect on the expression of target genes was monitored. Administration of RG108 before the test led to a short-lasting, dose-dependent increase in pattern separation memory that was not present anymore after 48 h. Furthermore, treatment with RG108 did not enhance long-term memory of the animals when tested after a 24 h inter-trial interval in the same task. At the transcriptomic level, acute treatment with RG108 was accompanied by increased expression of Bdnf1, while expression of Bdnf4, Bdnf9, Gria1 and Hdac2 was not altered within 1 h after treatment. Methylation analysis of 14 loci in the promoter region of Bdnf1 revealed a counterintuitive increase in the levels of DNA methylation at three CpG sites. Taken together, these results indicate that acute administration of RG108 has a short-lasting pro-cognitive effect on object pattern separation that could be explained by increased Bdnf1 expression. The observed increase in Bdnf1 methylation suggests a complex interplay between Bdnf methylation-demethylation that promotes Bdnf1 expression and associated cognitive performance. Considering that impaired pattern separation could constitute the underlying problem of a wide range of mental and cognitive disorders, pharmacological agents including DNA methylation inhibitors that improve pattern separation could be compelling targets for the treatment of these disorders. In that respect, future studies are needed in order to determine the effect of chronic administration of such agents.},

Likability seems to exert a substantial bias on student evaluations of teaching, albeit one that is overestimated when measured at the time of evaluation.

The pathophysiology remains unclear, however, there is increasing evidence for involvement of the peripheral nervous system with a high prevalence of small fiber pathology (SFP). The aim of this systematic literature review is to establish the prevalence of SFP in fibromyalgia. Methods An electronic literature search was performed using MEDLINE, EMBASE, PubMed, Web of Science, CINAHL and the Cochrane Library databases. Published full-text, English language articles that provide SFP prevalence data in studies of fibromyalgia of patients over 18years old were included. All articles were screened by two independent reviewers using a priori criteria. Methodological quality and risk of bias were evaluated using the critical appraisal tool by Munn et al. Overall and subgroup pooled prevalence were calculated by random-effects meta-analysis with 95\% CI. Results Database searches found 935 studies; 45 articles were screened of which 8 full text articles satisfied the inclusion criteria, providing data from 222 participants. The meta-analysis demonstrated the pooled prevalence of SFP in fibromyalgia is 49\% (95\% CI: 38-60\%) with a moderate degree of heterogeneity, (I2= 68\%). The prevalence estimate attained by a skin biopsy was 45\% (95\% CI: 32-59\%, I2= 70\%) and for corneal confocal microscopy it was 59\% (95\% CI: 40-78\%, I2= 51\%). Conclusion There is a high prevalence of SFP in fibromyalgia. This study provides compelling evidence of a distinct phenotype involving SFP in fibromyalgia. Identifying SFP will aid in determining its relationship to pain and potentially facilitate the development of future interventions and pharmacotherapy.},

  abstract  = {Drosophila melanogaster is a long-standing model organism in the circadian clock research. A major advantage is the relative small number of about 150 neurons, which built the circadian clock in Drosophila. In our recent work, we focused on the neuroanatomical properties of the lateral neurons of the clock network. By applying the multicolor-labeling technique Flybow we were able to identify the anatomical similarity of the previously described E2 subunit of the evening oscillator of the clock, which is built by the 5th small ventrolateral neuron (5th s-LNv) and one ITP positive dorsolateral neuron (LNd). These two clock neurons share the same spatial and functional properties. We found both neurons innervating the same brain areas with similar pre- and postsynaptic sites in the brain. Here the anatomical findings support their shared function as a main evening oscillator in the clock network like also found in previous studies. A second quite surprising finding addresses the large lateral ventral PDF-neurons (l-LNvs). We could show that the four hardly distinguishable l-LNvs consist of two subgroups with different innervation patterns. While three of the neurons reflect the well-known branching pattern reproduced by PDF immunohistochemistry, one neuron per brain hemisphere has a distinguished innervation profile and is restricted only to the proximal part of the medulla-surface. We named this neuron "extra" l-LNv (l-LNvx). We suggest the anatomical findings reflect different functional properties of the two l-LNv subgroups.},

  abstract  = {Background Cerebral microbleeds are a neuroimaging biomarker of stroke risk. A crucial clinical question is whether cerebral microbleeds indicate patients with recent ischaemic stroke or transient ischaemic attack in whom the rate of future intracranial haemorrhage is likely to exceed that of recurrent ischaemic stroke when treated with antithrombotic drugs. We therefore aimed to establish whether a large burden of cerebral microbleeds or particular anatomical patterns of cerebral microbleeds can identify ischaemic stroke or transient ischaemic attack patients at higher absolute risk of intracranial haemorrhage than ischaemic stroke. Methods We did a pooled analysis of individual patient data from cohort studies in adults with recent ischaemic stroke or transient ischaemic attack. Cohorts were eligible for inclusion if they prospectively recruited adult participants with ischaemic stroke or transient ischaemic attack; included at least 50 participants; collected data on stroke events over at least 3 months follow-up; used an appropriate MRI sequence that is sensitive to magnetic susceptibility; and documented the number and anatomical distribution of cerebral microbleeds reliably using consensus criteria and validated scales. Our prespecified primary outcomes were a composite of any symptomatic intracranial haemorrhage or ischaemic stroke, symptomatic intracranial haemorrhage, and symptomatic ischaemic stroke. We registered this study with the PROSPERO international prospective register of systematic reviews, number CRD42016036602. Findings Between Jan 1, 1996, and Dec 1, 2018, we identified 344 studies. After exclusions for ineligibility or declined requests for inclusion, 20 322 patients from 38 cohorts (over 35 225 patient-years of follow-up; median 1·34 years [IQR 0·19-2·44]) were included in our analyses. The adjusted hazard ratio [aHR] comparing patients with cerebral microbleeds to those without was 1·35 (95\% CI 1·20-1·50) for the composite outcome of intracranial haemorrhage and ischaemic stroke; 2·45 (1·82-3·29) for intracranial haemorrhage and 1·23 (1·08-1·40) for ischaemic stroke. The aHR increased with increasing cerebral microbleed burden for intracranial haemorrhage but this effect was less marked for ischaemic stroke (for five or more cerebral microbleeds, aHR 4·55 [95\% CI 3·08-6·72] for intracranial haemorrhage vs 1·47 [1·19-1·80] for ischaemic stroke; for ten or more cerebral microbleeds, aHR 5·52 [3·36-9·05] vs 1·43 [1·07-1·91]; and for ≥20 cerebral microbleeds, aHR 8·61 [4·69-15·81] vs 1·86 [1·23-2·82]). However, irrespective of cerebral microbleed anatomical distribution or burden, the rate of ischaemic stroke exceeded that of intracranial haemorrhage (for ten or more cerebral microbleeds, 64 ischaemic strokes [95\% CI 48-84] per 1000 patient-years vs 27 intracranial haemorrhages [17-41] per 1000 patient-years; and for ≥20 cerebral microbleeds, 73 ischaemic strokes [46-108] per 1000 patient-years vs 39 intracranial haemorrhages [21-67] per 1000 patient-years). Interpretation In patients with recent ischaemic stroke or transient ischaemic attack, cerebral microbleeds are associated with a greater relative hazard (aHR) for subsequent intracranial haemorrhage than for ischaemic stroke, but the absolute risk of ischaemic stroke is higher than that of intracranial haemorrhage, regardless of cerebral microbleed presence, antomical distribution, or burden.},

  abstract  = {Background Medulloblastoma is associated with rare hereditary cancer predisposition syndromes; however, consensus medulloblastoma predisposition genes have not been defined and screening guidelines for genetic counselling and testing for paediatric patients are not available. We aimed to assess and define these genes to provide evidence for future screening guidelines. Methods In this international, multicentre study, we analysed patients with medulloblastoma from retrospective cohorts (International Cancer Genome Consortium [ICGC] PedBrain, Medulloblastoma Advanced Genomics International Consortium [MAGIC], and the CEFALO series) and from prospective cohorts from four clinical studies (SJMB03, SJMB12, SJYC07, and I-HIT-MED). Whole-genome sequences and exome sequences from blood and tumour samples were analysed for rare damaging germline mutations in cancer predisposition genes. DNA methylation profiling was done to determine consensus molecular subgroups: WNT (MBWNT), SHH (MBSHH), group 3 (MBGroup3), and group 4 (MBGroup4). Medulloblastoma predisposition genes were predicted on the basis of rare variant burden tests against controls without a cancer diagnosis from the Exome Aggregation Consortium (ExAC). Previously defined somatic mutational signatures were used to further classify medulloblastoma genomes into two groups, a clock-like group (signatures 1 and 5) and a homologous recombination repair deficiency-like group (signatures 3 and 8), and chromothripsis was investigated using previously established criteria. Progression-free survival and overall survival were modelled for patients with a genetic predisposition to medulloblastoma. Findings We included a total of 1022 patients with medulloblastoma from the retrospective cohorts (n=673) and the four prospective studies (n=349), from whom blood samples (n=1022) and tumour samples (n=800) were analysed for germline mutations in 110 cancer predisposition genes. In our rare variant burden analysis, we compared these against 53 105 sequenced controls from ExAC and identified APC, BRCA2, PALB2, PTCH1, SUFU, and TP53 as consensus medulloblastoma predisposition genes according to our rare variant burden analysis and estimated that germline mutations accounted for 6\% of medulloblastoma diagnoses in the retrospective cohort. The prevalence of genetic predispositions differed between molecular subgroups in the retrospective cohort and was highest for patients in the MBSHH subgroup (20\% in the retrospective cohort). These estimates were replicated in the prospective clinical cohort (germline mutations accounted for 5\% of medulloblastoma diagnoses, with the highest prevalence [14\%] in the MBSHH subgroup). Patients with germline APC mutations developed MBWNT and accounted for most (five [71\%] of seven) cases of MBWNT that had no somatic CTNNB1 exon 3 mutations. Patients with germline mutations in SUFU and PTCH1 mostly developed infant MBSHH. Germline TP53 mutations presented only in childhood patients in the MBSHH subgroup and explained more than half (eight [57\%] of 14) of all chromothripsis events in this subgroup. Germline mutations in PALB2 and BRCA2 were observed across the MBSHH, MBGroup3, and MBGroup4 molecular subgroups and were associated with mutational signatures typical of homologous recombination repair deficiency. In patients with a genetic predisposition to medulloblastoma, 5-year progression-free survival was 52\% (95\% CI 40-69) and 5-year overall survival was 65\% (95\% CI 52-81); these survival estimates differed significantly across patients with germline mutations in different medulloblastoma predisposition genes. Interpretation Genetic counselling and testing should be used as a standard-of-care procedure in patients with MBWNT and MBSHH because these patients have the highest prevalence of damaging germline mutations in known cancer predisposition genes. We propose criteria for routine genetic screening for patients with medulloblastoma based on clinical and molecular tumour characteristics.},

In the solid-state, most different aggregates could be determined depending on the metal and additional Lewis bases. The crown-ether complexes of sodium (1-Na) and potassium (1-K) exhibited different structures, with sodium preferring coordination to the nitrogen end, whereas potassium binds in an unusual η2-coordination mode to the two central carbon atoms. The formation of the yldiide was accompanied by structural changes leading to shorter C-C and longer C-N bonds. This could be attributed to the delocalization of the free electron pairs at the carbon atom into the antibonding orbitals of the CN moiety, which was confirmed by IR spectroscopy and computational studies. Detailed density functional theory calculations show that the changes in the structure and the bonding situation were most pronounced in the lithium compounds due to the higher covalency.},

  abstract  = {The anomalies in the B-meson sector, in particular R-K(*) and R-D(*), are often interpreted as hints for physics beyond the Standard Model. To this end, leptoquarks or a heavy Z' represent the most popular SM extensions which can explain the observations. However, adding these fields by hand is not very satisfactory as it does not address the big questions like a possible embedding into a unified gauge theory. On the other hand, light leptoquarks within a unified framework are challenging due to additional constraints such as lepton flavor violation. The existing accounts typically deal with this issue by providing estimates on the relevant couplings. In this letter we consider a complete model based on the SU(4)(C) circle times SU(2)(L) circle times U(1) R gauge symmetry, a subgroup of SO(10), featuring both scalar and vector leptoquarks. We demonstrate that this setup has, in principle, all the potential to accommodate R-K(*) and R-D(*) while respecting bounds from other sectors usually checked in this context. However, it turns out that K-L -> e(+/-)mu(-/+) severely constraints not only the vector but also the scalar leptoquarks and, consequently, also the room for any sizeable deviations of R-K(*) from 1. We briefly comment on the options for extending the model in order to conform this constraint. Moreover, we present a simple criterion for all-orders proton stability within this class of models.},

After 1 year of open-label migalastat therapy, patients showed significant changes in alpha-galactosidase-A activity (0.06-0.2 nmol/minute/mg protein; P = 0.001), left ventricular myocardial mass index (137-130 g/m2; P = 0.037), and serum creatinine (0.94-1.0 mg/dL; P = 0.021), accounting for deterioration in estimated glomerular filtration rate (87-78 mL/minute/1.73 m2; P = 0.012). The enzymatic increase correlated with myocardial mass reduction (r = -0.546; P = 0.044) but not with renal function (r = -0.086; P = 0.770). Plasma globotriaosylsphingosine was reduced in therapy-naive patients (10.9-6.0 ng/mL; P = 0.021) and stable (9.6-12.1 ng/mL; P = 0.607) in patients switched from prior enzyme-replacement therapy. These first real-world data show that migalastat substantially increases alpha-galactosidase-A activity, stabilizes related serum biomarkers, and improves cardiac integrity in male and female patients with amenable Fabry disease mutations.},

  abstract  = {Activating delayed fluorescence emission in a dilute solution via a non-covalent approach is a formidable challenge. In this report, we propose a strategy for efficient delayed fluorescence generation in dilute solution using a non-covalent approach via supramolecularly engineered cyclophane-based nanoenvironments that provide sufficient binding strength to π-conjugated guests and that can stabilize triplet excitons by reducing vibrational dissipation and lowering the singlet-triplet energy gap for efficient delayed fluorescence emission. Toward this goal, a novel biphenyl bisimide-derived cyclophane is introduced as an electron-deficient and efficient triplet-generating host. Upon encapsulation of various carbazole-derived guests inside the nanocavity of this cyclophane, emissive charge transfer (CT) states close to the triplet energy level of the biphenyl bisimide are generated. The experimental results of host-guest studies manifest high association constants up to 10\(^4\) M\(^{-1}\) as the prerequisite for inclusion complex formation, the generation of emissive CT states, and triplet-state stabilization in a diluted solution state. By means of different carbazole guest molecules, we could realize tunable delayed fluorescence emission in this carbazole-encapsulated biphenyl bisimide cyclophane in methylcyclohexane/carbon tetrachloride solutions with a quantum yield (QY) of up to 15.6\%. Crystal structure analyses and solid-state photophysical studies validate the conclusions from our solution studies and provide insights into the delayed fluorescence emission mechanism.},

  abstract  = {Opioid receptors (ORs) are among the most intensively studied members of the G protein-coupled receptor (GPCR) family due to their important role in pain management and their involvement in psychological and neurological disorders. However, currently available opioid drugs exhibit both serious drawbacks, such as addiction, and life-threatening side effects, such as respiratory depression. Contrary to the classic monomeric model, indirect evidence suggests that ORs might form dimers, which could be endowed with a distinct pharmacological profile, and, thus, be exploited to develop innovative drugs. However, direct evidence for the spontaneous formation of OR dimers in living cells under physiological condition are missing. The focus of this thesis was the design, synthesis and characterization of new, highly subtype-selective OR fluorescent ligands to be used as tools for state-of-the-art microscopy methods, such as single molecule microscopy (SMM), in heterologous cells and potentially in native tissue, in order to investigate OR organization and mobility on the surface of intact, living cells, at low/physiological expression levels. The μOR is the OR subtype which plays the most critical role in pain modulation, while mediating the effects of the most powerful analgesic drugs. Also, it is the OR subtype which is mostly responsible for the major adverse effects of the currently marketed opioid drugs. We aimed to develop a new μOR-selective fluorescent ligand with a potential irreversible binding mode. Although the approach was in principle successful, i.e. the labelled cells were visible and distinguishable; this initial attempt was not suitable for SMM due to the ligands' poor selectivity and affinity as well as due to its high background noise. A second generation of the fluorescent ligand was designed; however the synthesis and characterization are part of another doctoral thesis. Lately, δOR has received attention as a promising drug target, due to its distinct pharmacological profile which features low abuse liability and lack of physical dependence. In addition, δOR expression has been associated with cancer regulation in the periphery, thus further highlighting the interest of imaging tools for this receptor. In this thesis, the development and characterization of two new δOR-selective fluorescent probes with excellent optical properties, based on the well-studied ligand naltrindole (NTI) is presented. Their application in SMM studies is currently underway at the group of Prof. Dr. Davide Calebiro at the University of Birmingham. The κOR is a subtype which has also emerged as a drug target due to its low abuse potential. Despite a growing interest in this receptor, κOR-selective fluorescent probes have been particularly scarce in literature. Herein, the design, synthesis and characterization of the first reported set of fluorescent κOR-selective probes with antagonistic properties, based on the established ligand 5'-guanidinonaltrindole (5'-GNTI) is presented. Two of these were employed for SMM experiments to investigate κOR homodimerization, localization and trafficking. Our findings do not support homodimerization of the κOR-bound probe complexes, while showing that the majority of them follow a normal Brownian diffusion on the cell surface.},

Dies gilt f{\"u}r eine Vielzahl von biotischen und abiotischen Faktoren. In der hier vorgelegten Arbeit wird der Effekt von erh{\"o}hten Temperaturen und Hitze genauer analysiert. Hitze ist einer der wichtigsten abiotischen Stressfaktoren, der das Pflanzenwachstum und die Reproduktion beeinflusst. Viele wichtige Kulturpflanzen zeigen immense Ertragseinbußen, die durch Hitze hervorgerufen werden. Durch den fortschreitenden Klimawandel werden jedoch Hitzeperioden immer h{\"a}ufiger und somit die Folgen f{\"u}r die Nahrungsproduktion immer gravierender. Zur Z{\"u}chtung von Pflanzen die hitzetolerant sind und weniger hohe Ertragseinbußen unter diesem Stress aufweisen, ist es essenziell die grundlegenden molekularen Mechanismen der Hitzetoleranz zu verstehen. Es m{\"u}ssen die verschiedenen physiologischen und biochemischen Prozesse identifiziert werden, die es Pflanzen erm{\"o}glichen, sich anzupassen. Es ist bekannt, dass die Anpassungsmechanismen von Pflanzen komplex sind und sowohl Ver{\"a}nderungen auf zellul{\"a}rer wie auch auf organismischer Ebene beinhalten. Ziel dieser Arbeit war es, weitere Erkenntnisse zu gewinnen, wie diese Anpassung vonstattengeht und welche molekularen Prozesse an ihr beteiligt sind. Ein Hauptaugenmerk lag dabei auf dem Einfluss des Lipidmetabolismus und den daran beteiligten Enzymen. Es konnte bereits gezeigt werden, dass die Akkumulation von Triacylglycerolen bei hohen Temperaturen die basale Thermotoleranz bei Arabidopsis thaliana erh{\"o}ht. Wie jedoch der genaue Mechanismus dieser durch Triacylglycerole vermittelten Thermotoleranz funktioniert, war bis dato nicht bekannt. Ich konnte zeigen, dass die angesammelten Triacylglycerole genutzt werden k{\"o}nnen, um die Stomata w{\"a}hrend des Hitzestress zu {\"o}ffnen. Dies f{\"u}hrt zu einer erh{\"o}hten Transpiration und somit einer K{\"u}hlung der Bl{\"a}tter. Der Abbau von Triacylglycerolen und St{\"a}rke am Morgen ist notwendig, um die Stomata zu {\"o}ffnen. Zus{\"a}tzlich dient der Abbau der Aufrechterhaltung des Citratzyklus und somit der Energieversorgung. In weiteren Experimenten konnte ich durch F{\"u}tterung mit stabil markierter Laurins{\"a}ure zeigen, dass die Triacylglycerole auch dem Aufbau neuer Aminos{\"a}uren unter Stressbedingungen dienen. Die hier vorgestellten Arbeiten bieten die Grundlage, um den Mechanismus der Thermotoleranz besser zu verstehen. Das Verst{\"a}ndnis der in dieser Arbeit beschriebenen molekularen Signalwege und Enzyme kann langfristig dazu beitragen hitzeresistentere Nutzpflanzen zu z{\"u}chten.},

  abstract  = {Der prim{\"a}re Hyperaldosteronismus (PA) stellt aktuell den h{\"a}ufigsten Grund f{\"u}r das Vorliegen einer sekund{\"a}ren Hypertonie dar. Der in der Best{\"a}tigungsdiagnostik verwendete Kochsalzbelastungstest basiert dabei auf einem fehlenden Absinken der Aldosteronkonzentration im Testverlauf bei Patient:innen mit PA im Vergleich zu Patient:innen mit essentieller Hypertonie (EH). Die Konzentrationsbestimmung erfolgte bisher mittels Immunoassay. Mit der LC-MS/MS steht jedoch mittlerweile eine weitere wichtige analytische Methode in der quantitativen Bestimmung von Steroidhormonen zur Verf{\"u}gung, welche in dieser Arbeit im Hinblick auf den Kochsalzbelastungstest untersucht wurde. Hohe Bedeutung kommt außerdem der Subtypdifferenzierung des PA zu, da die {\"A}tiologie der Erkrankung wegweisend f{\"u}r die Art der Therapie ist. Das Ziel dieser Studie war einerseits die Ermittlung eines LC-MS/MS-spezifischen Aldosteron-Cut-off-Wertes im Kochsalzbelastungstest und die Evaluation des Nutzens der Bestimmung von Steroidprofilen in der Diagnostik des PA. Zum anderen wurde der diagnostische Nutzen des Orthostasetests zur Unterscheidung von unilateraler und bilateraler Genese bei vorliegendem PA untersucht. Im Rahmen dieser Studien wurden 187 bzw. 158 Patient:innen analysiert, die zwischen 2009 und 2019 bei Verdacht auf oder Vorliegen eines PA im Universit{\"a}tsklinikum W{\"u}rzburg vorstellig wurden. Die Diagnose wurde gem{\"a}ß der aktuellen Leitlinie anhand der Ergebnisse des Kochsalzbelastungstests, NNVKs, Bildgebung und postoperativen Outcomes gestellt. Mithilfe der LC-MS/MS wurden erneut die Aldosteronkonzentrationen der aufbewahrten Serumproben des Kochsalzbelastungstests, sowie ein erweitertes Steroidpanel bestimmt. Unter Verwendung einer ROC-Analyse wurden die jeweils bestehenden Cut-off-Werte optimiert bzw. neu ermittelt. Die mittels Immunoassay bestimmten Aldosteronkonzentrationen lagen um 28 ng/L h{\"o}her als die mittels LC-MS/MS bestimmten Konzentrationen.

  abstract  = {The molecular basis of signal-dependent transcriptional activation has been extensively studied in macrophage polarization, but our understanding remains limited regarding the molecular determinants of repression. Here we show that IL-4-activated STAT6 transcription factor is required for the direct transcriptional repression of a large number of genes during in vitro and in vivo alternative macrophage polarization. Repression results in decreased lineage-determining transcription factor, p300, and RNA polymerase II binding followed by reduced enhancer RNA expression, H3K27 acetylation, and chromatin accessibility. The repressor function of STAT6 is HDAC3 dependent on a subset of IL-4-repressed genes. In addition, STAT6-repressed enhancers show extensive overlap with the NF-κB p65 cistrome and exhibit decreased responsiveness to lipopolysaccharide after IL-4 stimulus on a subset of genes. As a consequence, macrophages exhibit diminished inflammasome activation, decreased IL-1β production, and pyroptosis. Thus, the IL-4-STAT6 signaling pathway establishes an alternative polarization-specific epigenenomic signature resulting in dampened macrophage responsiveness to inflammatory stimuli.},

  abstract  = {Staphylococcus (S.) aureus is a leading cause of bacterial infection world-wide, and currently no vaccine is available for humans. Vaccine development relies heavily on clinically relevant infection models. However, the suitability of mice for S. aureus infection models has often been questioned, because experimental infection of mice with human-adapted S. aureus requires very high infection doses. Moreover, mice were not considered to be natural hosts of S. aureus. The latter has been disproven by our recent findings, showing that both laboratory mice, as well as wild small mammals including mice, voles, and shrews, are naturally colonized with S. aureus. Here, we investigated whether mouse-and vole-derived S. aureus strains show an enhanced virulence in mice as compared to the human-adapted strain Newman. Using a step-wise approach based on the bacterial genotype and in vitro assays for host adaptation, we selected the most promising candidates for murine infection models out of a total of 254 S. aureus isolates from laboratory mice as well as wild rodents and shrews. Four strains representing the clonal complexes (CC) 8, 49, and 88 (n = 2) were selected and compared to the human-adapted S. aureus strain Newman (CC8) in murine pneumonia and bacteremia models. Notably, a bank vole-derived CC49 strain, named DIP, was highly virulent in BALB/c mice in pneumonia and bacteremia models, whereas the other murine and vole strains showed virulence similar to or lower than that of Newman. At one tenth of the standard infection dose DIP induced disease severity, bacterial load and host cytokine and chemokine responses in the murine bacteremia model similar to that of Newman. In the pneumonia model, DIP was also more virulent than Newman but the effect was less pronounced. Whole genome sequencing data analysis identified a pore-forming toxin gene, lukF-PV(P83)/lukM, in DIP but not in the other tested S. aureus isolates. To conclude, the mouse-adapted S. aureus strain DIP allows a significant reduction of the inoculation dose in mice and is hence a promising tool to develop clinically more relevant infection models.},

We have developed and validated a method to isolate, from human skin samples, and expand ABCB5+ MSCs that meet the guideline criteria of the International Society for Cellular Therapy. We are able to process these cells into a Good Manufacturing Practice-conforming, MSC-based advanced-therapy medicinal product. Methods To support the development of ABCB5+ MSCs for potential therapeutic topical, intramuscular and intravenous administration, we have tested our product in a series of Good Laboratory Practice-compliant nonclinical in-vivo studies addressing all relevant aspects of biosafety, including potential long-term persistence and proliferation, distribution to nontarget tissues, differentiation into undesired cell types, ectopic tissue formation, tumor formation and local tissue reaction. Results (i) Subcutaneous application of 1 × 107 ABCB5+ MSCs/animal and intravenous application of 2 × 106 ABCB5+ MSCs/animal, respectively, to immunocompromised mice did not result in safety-relevant biodistribution, persistence or proliferation of the cells; (ii) three monthly subcutaneous injections of ABCB5+ MSCs at doses ranging from 1 × 105 to 1 × 107 cells/animal and three biweekly intravenous injections of 2 × 106 ABCB5+ MSCs/animal, respectively, to immunocompromised mice were nontoxic and revealed no tumorigenic potential; and (iii) intramuscular injection of 5 × 106 ABCB5+ MSCs/animal to immunocompromised mice was locally well tolerated.

Using individual cell lines with specific mutations, we demonstrate a generic and rapid stratification pipeline for targeted tumor therapy. We improve in vitro models of tissue conditions by a biological matrix-based three-dimensional (3D) tissue culture that allows in vitro drug testing: It correctly shows a strong drug response upon gefitinib (Gef) treatment in a cell line harboring an EGFR-activating mutation (HCC827), but no clear drug response upon treatment with the HSP90 inhibitor 17AAG in two cell lines with KRAS mutations (H441, A549). In contrast, 2D testing implies wrongly KRAS as a biomarker for HSP90 inhibitor treatment, although this fails in clinical studies. Signaling analysis by phospho-arrays showed similar effects of EGFR inhibition by Gef in HCC827 cells, under both 2D and 3D conditions. Western blot analysis confirmed that for 3D conditions, HSP90 inhibitor treatment implies different p53 regulation and decreased MET inhibition in HCC827 and H441 cells. Using in vitro data (western, phospho-kinase array, proliferation, and apoptosis), we generated cell line-specific in silico topologies and condition-specific (2D, 3D) simulations of signaling correctly mirroring in vitro treatment responses. Networks predict drug targets considering key interactions and individual cell line mutations using the Human Protein Reference Database and the COSMIC database. A signature of potential biomarkers and matching drugs improve stratification and treatment in KRAS-mutated tumors. In silico screening and dynamic simulation of drug actions resulted in individual therapeutic suggestions, that is, targeting HIF1A in H441 and LKB1 in A549 cells. In conclusion, our in vitro tumor tissue model combined with an in silico tool improves drug effect prediction and patient stratification. Our tool is used in our comprehensive cancer center and is made now publicly available for targeted therapy decisions.},

  abstract  = {Medulloblastoma (MB) is the most common malignant primary pediatric brain cancer. Among the most aggressive subtypes, Group 3 and Group 4 originate from stem/progenitor cells, frequently metastasize, and often display the worst prognosis, yet we know the least about the molecular mechanisms driving their progression. Here, we show that the transcription factor orthodenticle homeobox 2 (OTX2) promotes self-renewal while inhibiting differentiation in vitro and increases tumor initiation from MB stem/progenitor cells in vivo. To determine how OTX2 contributes to these processes, we employed complementary bioinformatic approaches to characterize the OTX2 regulatory network and identified novel relationships between OTX2 and genes associated with neuronal differentiation and axon guidance signaling in Group 3 and Group 4 MB stem/progenitor cells. In particular, OTX2 levels were negatively correlated with semaphorin (SEMA) signaling, as expression of 9 SEMA pathway genes is upregulated following OTX2 knockdown with some being potential direct OTX2 targets. Importantly, this negative correlation was also observed in patient samples, with lower expression of SEMA4D associated with poor outcome specifically in Group 4 tumors. Functional proof-of-principle studies demonstrated that increased levels of select SEMA pathway genes are associated with decreased self-renewal and growth in vitro and in vivo and that RHO signaling, known to mediate the effects of SEMA genes, is contributing to the OTX2 KD phenotype. Our study provides mechanistic insight into the networks controlled by OTX2 in MB stem/progenitor cells and reveals novel roles for axon guidance genes and their downstream effectors as putative tumor suppressors in MB.},

Conclusion For the first time, we provide proof for the occurrence of TAFC in human urine. TAFC/creatinine index determination in urine showed promising results for diagnosis of IA offering the advantages of non-invasive sampling.

Data analysis was split into two groups of patients who received novel POS formulations for antifungal prophylaxis (posaconazole prophylaxis group) and antifungal therapy (posaconazole therapy group), respectively. Results Overall, 180 patients (151 in the posaconazole prophylaxis group and 29 in the posaconazole therapy group) from six German tertiary care centers and hospitalized between 05/2014 - 03/2016 were observed. Median age was 58 years (range: 19 - 77 years) and the most common risk factor for IFD was chemotherapy (n = 136; 76\%). In the posaconazole prophylaxis group and posaconazole therapy group, median POS serum levels at steady-state were 1,068 μg/L (IQR 573-1,498 μg/L) and 904 μg/L (IQR 728-1,550 μg/L), respectively (P = 0.776). During antifungal prophylaxis with POS, nine (6\%) probable/proven fungal breakthroughs were reported and overall survival rate of hospitalization was 86\%. The median overall duration of POS therapy was 18 days (IQR: 7 - 23 days). Fourteen patients (48\%) had progressive IFD under POS therapy, of these five patients (36\%) died related to or likely related to IFD. Conclusions Our study demonstrates clinical effectiveness of antifungal prophylaxis with novel POS formulations. In patients treated for possible/probable/proven IFD, we observed considerable mortality in patients receiving salvage treatment and with infections due to rare fungal species.},

  abstract  = {Markers of inflammation, including plasma C-reactive protein (CRP), are associated with an increased risk of cardiovascular disease, and it has been suggested that this association is causal. However, the relationship between inflammation and cardiovascular disease has not been extensively studied in patients with chronic kidney disease. To evaluate this, we used data from the Study of Heart and Renal Protection (SHARP) to assess associations between circulating CRP and LDL cholesterol levels and the risk of vascular and non-vascular outcomes. Major vascular events were defined as nonfatal myocardial infarction, cardiac death, stroke or arterial revascularization, with an expanded outcome of vascular events of any type. Higher baseline CRP was associated with an increased risk of major vascular events (hazard ratio per 3x increase 1.28; 95\% confidence interval 1.19-1.38). Higher baseline LDL cholesterol was also associated with an increased risk of major vascular events (hazard ratio per 0.6 mmol/L higher LDL cholesterol; 1.14, 1.06-1.22). Higher baseline CRP was associated with an increased risk of a range of non-vascular events (1.16, 1.12-1.21), but there was a weak inverse association between baseline LDL cholesterol and non-vascular events (0.96, 0.92-0.99). The efficacy of lowering LDL cholesterol with simvastatin/ezetimibe on major vascular events, in the randomized comparison, was similar irrespective of CRP concentration at baseline. Thus, decisions to offer statin-based therapy to patients with chronic kidney disease should continue to be guided by their absolute risk of atherosclerotic events. Estimation of such risk may include plasma biomarkers of inflammation, but there is no evidence that the relative beneficial effects of reducing LDL cholesterol depends on plasma CRP concentration.},

Despite high conductivity and large surface area, potential health and safety concerns limit the use of nanocarbon and add challenges to handling. Previously, it is shown that phosphate ultrasonic bonding is ineffective for organic materials but in this study, it is found that by a preliminary oxidizing treatment, several carbons can be readily assembled from xerogels. Assembling nanocarbon into microparticles can usually require a binder or surfactants, which can reduce surface area or conductivity and generate a low microsphere yield. Carbon nanotube microspheres are nitrogen-doped and flower-like nanostructured Pt deposited on their surface, and finally showcased as efficient cathode electrocatalysts for the oxygen reduction reaction (half-wave potential 0.78 V vs reversible hydrogen electrode) and methanol oxidation (417 mA mg-1). In particular, no significant degradation of the catalysts is detected after 12 000 cycles (26.6 h).

In this study, MEW is adapted for the seeding of multicellular spheroids, which permits the easy handling as a single sheet-like tissue-scaffold construct. Spheroids are made from adipose-derived stromal cells (ASCs). Poly(ε-caprolactone) is processed via MEW into scaffolds with box-structured pores, readily tailorable to spheroid size, using 13-15 µm diameter fibers. Two 7-8 µm diameter "catching fibers" near the bottom of the scaffold are threaded through each pore (360 and 380 µm) to prevent loss of spheroids during seeding. Cell viability remains high during the two week culture period, while the differentiation of ASCs into the adipogenic lineage is induced. Subsequent sectioning and staining of the spheroid-scaffold construct can be readily performed and accumulated lipid droplets are observed, while upregulation of molecular markers associated with successful differentiation is demonstrated. Tailoring MEW scaffolds with pores allows the simultaneous seeding of high numbers of spheroids at a time into a construct that can be handled in culture and may be readily transferred to other sites for use as implants or tissue models.},

  abstract  = {In this study, we aimed to evaluate dosimetric approaches in ablation treatment of Differentiated Thyroid Carcinoma (DTC) without interrupting the clinical routine. Prior to therapy, 10.7 MBq 131I in average was orally given to 24 patients suffering from DTC. MIRD formalism was used for dosimetric calculations. For blood and bone marrow dosimetry, blood samples and whole-body counts were collected at 2, 24, 72, and 120 h after I-131 administration. For remnant tissue dosimetry, uptake measurements were performed at the same time intervals. To estimate the remnant volume, anterior and lateral planar gamma camera images were acquired with a reference source within the field of view at 24 h after I-131 administration. Ultrasound imaging was also performed. Treatment activities determined with the fixed activity method were administered to the patients. Secondary cancer risk relative to applied therapy was evaluated for dosimetric approaches. The average dose to blood and bone marrow were determined as 0.15 ± 0.04 and 0.11 ± 0.04 Gy/GBq, respectively. The average remnant tissue dose was 0.58 ± 0.52 Gy/MBq and the corresponding required activity to ablate the remnant was approximately 1.3 GBq of 131I. A strong correlation between 24th-hour uptake and time-integrated activity coefficient values was obtained. Compared to fixed activity method, approximately five times higher secondary cancer risk was determined in bone marrow dosimetry, while the risk was about three times lower in lesion-based dosimetry.},

  abstract  = {Recent progress in nanobiotechnology has attracted interest to a biomedical application of the carbon nanostructure C60 fullerene since it possesses a unique structure and versatile biological activity. C60 fullerene potential application in the frame of cancer photodynamic therapy (PDT) relies on rapid development of new light sources as well as on better understanding of the fullerene interaction with cells. The aim of this study was to analyze C60 fullerene effects on human leukemic cells (CCRF-CEM) in combination with high power single chip light-emitting diodes (LEDs) light irradiation of different wavelengths: ultraviolet (UV, 365 nm), violet (405 nm), green (515 nm) and red (632 nm). The time-dependent accumulation of fullerene C60 in CCRF-CEM cells up to 250 ng/106 cells at 24 h with predominant localization within mitochondria was demonstrated with immunocytochemical staining and liquid chromatography mass spectrometry. In a cell viability assay we studied photoexcitation of the accumulated C60 nanostructures with ultraviolet or violet LEDs and could prove that significant phototoxic effects did arise. A less pronounced C60 fullerene phototoxic effect was observed after irradiation with green, and no effect was detected with red light. A C60 fullerene photoactivation with violet light induced substantial ROS generation and apoptotic cell death, confirmed by caspase3/7 activation and plasma membrane phosphatidylserine externalization. Our work proved C60 fullerene ability to induce apoptosis of leukemic cells after photoexcitation with high power single chip 405 nm LED as a light source. This underlined the potential for application of C60 nanostructure as a photosensitizer for anticancer therapy.},

  abstract  = {Die zielgerichtete Therapie und die Immuncheckpoint-Inhibitoren haben die Tumortherapie revolutioniert. W{\"a}hrend erstere die Tumorzellen gezielt angreift, verhindern letztere die Hemmung des Immunsystems durch Immuncheckpoints, um eine robuste Immunantwort zu erreichen. Zus{\"a}tzlich ist das Nebenwirkungsprofil bei direktem Vergleich mit der konventionellen Chemotherapie g{\"u}nstiger. Beim HNSCC werden beide Ans{\"a}tze angewendet. Cetuximab ist ein monoklonaler Antik{\"o}rper, der sich gegen EGFR, welcher bei HNSCC {\"u}berexprimiert ist, richtet. Nivolumab und Pembrolizumab richten sich gegen das Immuncheckpoint-Protein PD-1. Nach wie vor sind die Resistenzen, sowohl die initialen als auch die erworbenen, die gr{\"o}ßte zu {\"u}berwindende Herausforderung. Aufbauend auf dem Ergebnis vorangegangener Arbeiten, die zeigen konnten, dass HGF {\"u}ber c-MET die Expression des Immuncheckpointliganden PD-L1 steigert, setzt sich diese Arbeit weiter mit den intrazellul{\"a}ren nachgeschalteten Signalwegen nach c-MET Aktivierung auseinander. Dies ist von besonderem Interesse, weil diese Signalwege ebenfalls f{\"u}r die Resistenzentwicklung verantwortlich sein k{\"o}nnen, zeitgleich k{\"o}nnen diese im Rahmen der zielgerichteten Therapie gezielt inhibiert werden. Um den HGF-Einfluss auf die intrazellul{\"a}ren Signalwege zu pr{\"u}fen, wurden vier etablierte HNSCC-Zelllinien herangezogen. Im ersten Teil der Arbeit wurden die 4 HNSCC-abgeleitete Zelllinien mit HGF stimuliert und mittels Western Blot der PD-L1-Anstieg und die Phosphorylierungs{\"a}nderung der Schl{\"u}sselproteine der einzelnen Signalwege nachgewiesen. Daraus ergab sich, dass HGF die MAPK- und PIK3/AKT-Signalwege aktiviert. W{\"a}hrend eine kombinierte Blockade des MAPK-Signalwegs den PD-L1-Anstieg vollst{\"a}ndig verhindern konnte, hemmte die PIK3/AKT-Blockade den PD-L1-Anstieg nur partiell. Im zweiten Teil wurde mit siRNA der haupts{\"a}chlich f{\"u}r den PD-L1-Anstieg zust{\"a}ndige MAPK-Signalweg unterbunden, was mittels quantitativer PCR auf der mRNA-Ebene nachgewiesen werden konnte. Mittels Western Blot konnte entsprechend gezeigt werden, dass der PD-L1-Anstieg trotz HGF-Stimulation bei nicht funktionsf{\"a}higem MAPK-Signalweg eingeschr{\"a}nkt war. Weiter wurde der Effekt mit dem Medikament Trametinib, das im Rahmen der zielgerichteten Therapie bei malignem Melanom und NSCLC f{\"u}r die MAPK-Signalweg-Hemmung zugelassen ist, evaluiert. Sowohl im Western Blot als auch in der Durchflusszytometrie konnte best{\"a}tigt werden, dass Trametinib den HGF-induzierten Anstieg von PD-L1 signifikant blockiert. Dar{\"u}ber hinaus konnte im Rahmen der Western Blot-Versuche gezeigt werden, dass die Signalwege und die PD-L1-Expression in den Zelllinien unterschiedlich aktiv bzw. hoch waren. Unter den vier Zelllinien zeigte die FaDu-Zelllinie eine erh{\"o}hte PI3K/AKT-Aktivit{\"a}t, Detroit562 und SCC9 eine erh{\"o}hte MAPK-Aktivit{\"a}t. Die PD-L1- Expression war in der SCC9-Zelllinie am h{\"o}chsten. Die Arbeit zeigt eine einheitliche Reaktion der HNSCC-Zelllinien auf den Wachstumsfaktor HGF, welcher im Tumormilieu von HNSCC oft in hoher Konzentration vorhanden ist. Neben dem EGFR-Antik{\"o}rper (Cetuximab) kann eine kombinierte Hemmung entweder von c-MET oder von den nachgeschalteten Signalwegen MAPK und PI3K/AKT bei Resistenzen, Progression oder Unvertr{\"a}glichkeiten eine M{\"o}glichkeit f{\"u}r eine wirksamere Therapie von HNSCC darstellen. Ein Screening der Signalwege und deren Aktivierungsmechanismen k{\"o}nnte bei Resistenzen oder bei einem Rezidiv/Progress dazu beitragen, gezielt die alternative Aktivierung zu hemmen und m{\"o}glicherweise die Wirksamkeit einer Immuncheckpointblockade zu verbessern.},

Hierf{\"u}r wurden unterschiedlich fluoreszierende Proteine (LSSmKate2, EGFP, mTagBFP2) durch Anwendung eines Sleeping Beauty basierten Vektorsystems in unterschiedliche Sublinien der Myelom Zelllinie L363 eingebracht. Diese vier Sublinien beinhalten jeweils eine von drei aus prim{\"a}ren Patientenproben gewonnenen Mutationen in IKZF1 (A152T, E170D, R439H) oder den IKZF1 WT. Die Anwendung von immunmodulatorischen Medikamenten (IMiDs) f{\"u}hrt zu einer Ubiquitinierung des Transkriptionsfaktors IKZF1 durch die E3-Ubiquitin-Protein-Ligase (CRBN-CUL4). Durch Mutationen in IKZF1 kommt es zu St{\"o}rungen in diesem Prozess und damit zu einer {\"U}berexpression von IKZF1. Dies wirkt sich wachstumsf{\"o}rdert auf die Myelomzellen aus. Die Auswirkungen der einzelnen Mutationen in IKZF1 ist aufgrund dessen ein klinisch relevantes Forschungsthema. In dieser Arbeit wurden jeweils zwei Sublinien mit Zellen des IKZF1 WT und Zellen mit einer IKZF1 Mutation mit jeweils unterschiedlich fluoreszierenden Proteinen markiert. Diese wurden gemeinsam unter Behandlung mit verschiedenen Konzentrationen von Lenalidomid inkubiert. Somit konnte das Selektionsverhalten mittels Durchflusszytometrie-Auswertungen visualisiert werden. Es konnte gezeigt werden, dass die IKZF1 Mutation A152T einen deutlichen Selektionsvorteil f{\"u}r die Myelomzellen darstellt. Bei den IKZF1 Mutationen E170D und R439H konnte kein Selektionsvorteil gegen{\"u}ber dem IKZF1 WT beobachtet werden.},

  abstract  = {Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent developmental disorders, affecting 5.9\% children and adolescents and 2.5\% adults worldwide. The core characteristics are age-inappropriate levels of hyperactivity, impulsivity and inattention, often accompanied by co-morbidities such as mood and conduct disorders as wells as learning deficits. In the majority of cases, ADHD is caused by an interplay of accumulated genetic and environmental risk factors. Twin studies report a very high heritability of 70-80\%, however, common genetic variants in the population only explain a third of the heritability. The rest of the genetic predisposition is composed of rare copy number variations (CNVs) and gene x environment interactions including epigenetic alterations. Through genome wide association (GWAS) and linkage studies a number of likely candidate genes were identified. A handful of them play a role in dopamine or noradrenaline neurotransmitter systems, simultaneously those systems are the main targets of common drug treatment approaches. However, for the majority of candidates the biological function in relation to ADHD is unknown. It is crucial to identify those functions in order to gain a deeper understanding of the pathomechanism and genetic networks potentially responsible for the disorder. This work focuses on the three candidate genes GFOD1, SLC2A3 and LBX1 and their role in the healthy organism as well as in case of ADHD. The neuroanatomy was regarded through expression analysis and various behavioural assays of activity were performed to link alterations on the transcript level to phenotypes associated with the neurodevelopmental disorder. Zebrafish orthologues of the human risk genes were identified and extensive temporal and spacial expression characterisation performed via RNA in situ hybridisation. Through morpholino derived knock-down and mRNA overexpression zebrafish models with subsequent behavioural analysis, both hyper- and hypoactive phenotypes were discovered. Additional expression analysis through double in situ hybridisation revealed a co-localisation during zebrafish neurodevelopment of each gfod1 and slc2a3a together with gad1b, a marker for GABAergic neurons. Interestingly, both risk genes have previously been associated with glucose homeostasis and energy metabolism, which when disrupted could lead to alterations in signal transduction and neuron survival. Likewise, Lbx1 plays a pivotal role in GABAergic versus glutamatergic neuron specification during spinal cord and hindbrain development in mice and chicken. Preliminary results of this work suggest a similar role in zebrafish. Taken together, those findings on the one hand represent a sturdy basis to con- tinue studies of the function of the genes and on the other hand open up the opportunity to investigate novel aspects of ADHD research by exploring the role of the GABAergic neurotransmitter system or the connection between energy metabolism and psychiatric disorders.},

  abstract  = {The present thesis is concerned with the automated computation of integrated and differential cross sections of diboson production in proton-proton and electron-positron collisions at very high energies, including a resummation of electroweak Sudakov logarithms to all orders in the fine-structure constant using soft-collinear effective theory. The search for new physics at future colliders such as the FCC-hh or the CLIC requires precise predictions for scattering cross sections from the theoretical high-energy physics com- munity. Electroweak Sudakov logarithms, which currently limit the accuracy of predictions in the high-energy tails of differential distributions for LHC-like energies, are known to destroy the convergence behaviour of the fixed-order perturbative series, once sufficiently high energies are considered. To resum these large corrections, soft-collinear effective theory has been applied to simple processes, which permits analytic calculations. Within this work, we present an automated computation within a Monte Carlo integration framework, thus facilitating the computation of fully differential cross section to complicated processes. This requires the use of the Catani- Seymour subtraction algorithm to treat the occurring infrared divergences. The machinery is applied to all diboson processes with intermediate weak gauge bosons, including the photon- induced W+ W- -production channel. To this end we carefully study the validity of the necessary assumptions such as the double- pole approximation and estimate the order of magnitude of neglected effects. Especially the non-doubly-resonant contributions turn out to be sizeable in several interesting phase-space regions. For lepton collisions at 3 TeV we obtain the integrated cross sections of W-pair and Z-pair production to be shifted by more than 20\% with respect to the Born value, owing to the resum- mation of the leading-logarithmic corrections These effects are partly cancelled by subleading effects. For proton-proton collisions at √ s = 100 TeV we observe sizeable resummation effects in the high-energy tails, while the integrated cross sections are dominated by interactions, for which soft-collinear effective theory is not applicable.},

  abstract  = {The negative societal impacts associated with the increasing prevalence of violence and aggression is increasing, and, with this rise, is the need to understand the molecular and cellular changes that underpin ultrasound-induced aggressive behavior. In mice, stress-induced aggression is known to alter AMPA receptor subunit expression, plasticity markers, and oxidative stress within the brain. Here, we induced aggression in BALB/c mice using chronic ultrasound exposure and examined the impact of the psychoactive anti-oxidant compounds thiamine (vitamin B1), and its derivative benfotiamine, on AMPA receptor subunit expression, established plasticity markers, and oxidative stress. The administration of thiamine or benfotiamine (200 mg/kg/day) in drinking water decreased aggressive behavior following 3-weeks of ultrasound exposure and benfotiamine, reduced floating behavior in the swim test. The vehicle-treated ultrasound-exposed mice exhibited increases in protein carbonyl and total glutathione, altered AMPA receptor subunits expression, and decreased expression of plasticity markers. These ultrasound-induced effects were ameliorated by thiamine and benfotiamine treatment; in particular both antioxidants were able to reverse ultrasound-induced changes in GluA1 and GluA2 subunit expression, and, within the prefrontal cortex, significantly reversed the changes in protein carbonyl and polysialylated form of neural cell adhesion molecule (PSA-NCAM) expression levels. Benfotiamine was usually more efficacious than thiamine. Thus, the thiamine compounds were able to counteract ultrasound-induced aggression, which was accompanied by the normalization of markers that have been showed to be associated with ultrasound-induced aggression. These commonly used, orally-active compounds may have considerable potential for use in the control of aggression within the community. This article is part of the Special Issue entitled 'Current status of the neurobiology of aggression and impulsivity'.},
