Enhanced virulence of CA-strains is partly attributed to increased production of toxins such as phenol-soluble modulins (PSM). The pathogen is internalized efficiently by mammalian host cells and intracellular S. aureus has recently been shown to contribute to disease. Upon internalization, cytotoxic S. aureus strains can disrupt phagosomal membranes and kill host cells in a PSM-dependent manner. However, PSM are not sufficient for these processes. Here we screened for factors required for intracellular S. aureus virulence. We infected escape reporter host cells with strains from an established transposon mutant library and detected phagosomal escape rates using automated microscopy. We thereby, among other factors, identified a non-ribosomal peptide synthetase (NRPS) to be required for efficient phagosomal escape and intracellular survival of S. aureus as well as induction of host cell death. By genetic complementation as well as supplementation with the synthetic NRPS product, the cyclic dipeptide phevalin, wild-type phenotypes were restored. We further demonstrate that the NRPS is contributing to virulence in a mouse pneumonia model. Together, our data illustrate a hitherto unrecognized function of the S. aureus NRPS and its dipeptide product during S. aureus infection.}, language = {en} } @article{ZahnertLoewenheimBeutneretal.2016, author = {Zahnert, Thomas and L{\"o}wenheim, Hubert and Beutner, Dirk and Hagen, Rudolf and Ernst, Arneborg and Pau, Hans-Wilhelm and Zehlicke, Thorsten and K{\"u}hne, Hilke and Friese, Natascha and Tropitzsch, Anke and L{\"u}ers, Jan-Christoffer and Mlynski, Robert and Todt, Ingo and H{\"u}ttenbrink, Karl-Bernd}, title = {Multicenter Clinical Trial of Vibroplasty Couplers to Treat Mixed/Conductive Hearing Loss: First Results}, series = {Audiology and Neurotology}, volume = {21}, journal = {Audiology and Neurotology}, number = {4}, issn = {1420-3030}, doi = {10.1159/000444616}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-199129}, pages = {212-222}, year = {2016}, abstract = {Objective: To evaluate the safety and effectiveness of round window (RW), oval window (OW), CliP and Bell couplers for use with an active middle ear implant. Methods: This is a multicenter, long-term, prospective trial with consecutive enrollment, involving 6 university hospitals in Germany. Bone conduction, air conduction, implant-aided warble-tone thresholds and Freiburger monosyllable word recognition scores were compared with unaided preimplantation results in 28 moderate-to-profound hearing-impaired patients after 12 months of follow-up. All patients had previously undergone failed reconstruction surgeries (up to 5 or more). In a subset of patients, additional speech tests at 12 months postoperatively were used to compare the aided with the unaided condition after implantation with the processor switched off. An established quality-of-life questionnaire for hearing aids was used to determine patient satisfaction. Results: Postoperative bone conduction remained stable. Mean functional gain for all couplers was 37 dB HL (RW = 42 dB, OW = 35 dB, Bell = 38 dB, CliP = 27 dB). The mean postoperative Freiburger monosyllable score was 71\% at 65 dB SPL. The postimplantation mean SRT50 (speech reception in quiet for 50\% understanding of words in sentences) improved on average by 23 dB over unaided testing and signal-to-noise ratios also improved in all patients. The International Outcome Inventory for Hearing Aids (IOI-HA)quality-of-life questionnaire was scored very positively by all patients. Conclusion: A significant improvement was seen with all couplers, and patients were satisfied with the device at 12 months postoperatively.

We examined the outcome following surgical or endovascular GIA treatment focusing on patient age, GIA location and unruptured GIA. Methods: Medline and Embase were searched for studies reporting on GIA treatment outcome published after January 2000. We calculated the proportion of good outcome (PGO) for all included GIA and for unruptured GIA by meta-analysis using a random effects model. Results: We included 54 studies containing 64 study populations with 1,269 GIA at a median follow-up time (FU-T) of 26.4 months (95\% CI 10.8-42.0). PGO was 80.9\% (77.4-84.4) in the analysis of all GIA compared to 81.2\% (75.3-86.1) in the separate analysis of unruptured GIA. For each year added to patient age, PGO decreased by 0.8\%, both for all GIA and unruptured GIA. For all GIA, surgical treatment resulted in a PGO of 80.3\% (95\% CI 76.0-84.6) compared to 84.2\% (78.5-89.8, p = 0.27) after endovascular treatment. In unruptured GIA, PGO was 79.7\% (95\% CI 71.5-87.8) after surgical treatment and 84.9\% (79.1-90.7, p = 0.54) after endovascular treatment. PGO was lower in high quality studies and in studies presenting aggregate instead of individual patient data. In unruptured GIA, the OR for good treatment outcome was 5.2 (95\% CI 2.0-13.0) at the internal carotid artery compared to 0.1 (0.1-0.3, p < 0.1) in the posterior circulation. Patient sex, FU-T and prevalence of ruptured GIA were not associated with PGO.

A dysbalance between FoxP3+ regulatory CD4+ T cells (Tregs) and inflammatory T-helper (Th) 17 cells has been suggested. Methods: The study aimed (1) to investigate the phenotypical and functional characteristics of Th17 and Tregs in SSc patients depending on disease manifestation (limited vs. diffuse cutaneous SSc, dcSSc) and activity, and (2) the transcriptional level and methylation status of Th17- and Treg-specific transcription factors. Results: There was a concurrent accumulation of circulating peripheral IL-17-producing CCR6+ Th cells and FoxP3+ Tregs in patients with dcSSc. At the transcriptional level, Th17- and Treg-associated transcription factors were elevated in SSc. A strong association with high circulating Th17 and Tregs was seen with early, active, and severe disease presentation. However, a diminished suppressive function on autologous lymphocytes was found in SSc-derived Tregs. Significant relative hypermethylation was seen at the gene level for RORC1 and RORC2 in SSc, particularly in patients with high inflammatory activity. Conclusions: Besides the high transcriptional activity of T cells, attributed to Treg or Th17 phenotype, in active SSc disease, Tregs may be insufficient to produce high amounts of IL-10 or to control proliferative activity of effector T cells in SSc. Our results suggest a high plasticity of Tregs strongly associated with the Th17 phenotype.

Als Ministerpr{\"a}sident und als Staatspr{\"a}sident verfolgte Poincar{\´e} eine Kriegsvorbereitungs- und Erpressungspolitik gegen{\"u}ber Berlin. Sie sollte nicht nur die Sicherheit Frankreichs vor Deutschland verb{\"u}rgen. Ihr Ziel und ihre Perspektive waren vielmehr die einer Revanche f{\"u}r 1870/71, um, analog zu Bismarcks Vorgehen in der „Hohenzollernkrise", die Berliner Reichsleitung in eine Situation zu man{\"o}vrieren, in der sich diese zur Flucht nach vorne in die Kriegsausl{\"o}sung entschloss. Deshalb wurde die Entente Cordiale mit England zu einem de facto-Milit{\"a}rb{\"u}ndnis ausgebaut; deshalb agierte Poincar{\´e} als Geburtshelfer der Unterhandlungen f{\"u}r eine Marinekonvention zwischen London und Petersburg; und deshalb gab er der Pariser Balkanpolitik eine neue Ausrichtung, indem er die seit 1893/94 bestehende Beistandsautomatik gegen{\"u}ber Rußland grundlegend modifizierte. Jetzt wurden die russischen Expansionsziele auf dem Balkan als handlungsleitendes Motiv der Pariser Politik adoptiert; jetzt wurde Petersburg angespornt, gegen Wien offensiv aufzutreten; jetzt bekamen die russischen Entscheidungstr{\"a}ger, anders als noch in der „bosnischen Annexionskrise", die Versicherung uneingeschr{\"a}nkten franz{\"o}sischen Beistands auf dem Balkan; und jetzt wurde mit Petersburg ein mit Anleihen unterf{\"u}ttertes Kompensationsgesch{\"a}ft abgeschlossen, das sich sowohl diplomatisch wie vor allem milit{\"a}risch gegen Deutschland richtete und die Pr{\"a}missen des Schlieffenplans zunehmend aushebelte. All diese Vorkehrungen dienten dazu, die Unzul{\"a}nglichkeiten der eigenen milit{\"a}rstrategischen Aufstellung gem{\"a}ß „Plan XVII" auszubalancieren, die offene belgische Flanke abzudichten, die eminenten Bedenken der eigenen Generalit{\"a}t zu zerstreuen und Frankreich in einem Krieg an der Seite Russlands und Englands eine Siegchance zu verschaffen. Vor allem aber erf{\"u}llten sie den Zweck, Deutschland herauszufordern und unter enormen Handlungsdruck zu setzen. Die von Poincar{\´e} angeheizten Einkreisungsphobien in der deutschen F{\"u}hrungsspitze ebneten somit Berlin den Weg in die hochriskante und nicht beherrschbare Konfrontations- und Risikopolitik der „Julikrise".

Nanog is necessary for the natural induction of pluripotency in early mammalian development but dispensable for both its maintenance and its artificial induction. To gain further insight into the molecular activity of Nanog, we analyzed the outcomes of Nanog gain-of-function in various cell models employing a recently developed biologically active recombinant cell-permeant protein, Nanog-TAT. We found that Nanog enhances the proliferation of both NIH 3T3 and primary fibroblast cells. Nanog transduction into primary fibroblasts results in suppression of senescence-associated beta-galactosidase activity. Investigation of cell cycle factors revealed that transient activation of Nanog correlates with consistent downregulation of the cell cycle inhibitor p27\(^{KIP1}\) (also known as CDKN1B). By performing chromatin immunoprecipitation analysis, we confirmed bona fide Nanog-binding sites upstream of the p27\(^{KIP1}\) gene, establishing a direct link between physical occupancy and functional regulation.

The aim of this article is to analyse corporate sustainability reporting amongst the world's largest companies and to assess the HRM aspects of sustainability within these reports in comparison to environmental aspects of sustainable management and whether organisational attributes - principally country-of-origin - influences the reporting of such practices. A focus in this article is the extent to which the reporting of various aspects of sustainability may reflect dominant models of corporate governance in the country in which a company is headquartered. The findings suggest, first and against expectations, that the overall disclosure on HRM-related performance is not lower than that on environmental performance.

The methylation changes on chromosome 21 appeared to be balanced between hypo- and hyper-methylation, whereas, consistent with prior reports, all other chromosomes showed 3-11times more hyper- than hypo-methylated sites. Reduced NRSF/REST expression due to upregulation of DYRK1A (on chromosome 21q22.13) and methylation of REST binding sites during early developmental stages may contribute to this genome-wide excess of hypermethylated sites. Upregulation of DNMT3L (on chromosome 21q22.4) could lead to de novo methylation in neuroprogenitors, which then persists in the fetal DS brain where DNMT3A and DNMT3B become downregulated. The vast majority of differentially methylated promoters and genes was hypermethylated in DS and located outside chromosome 21, including the protocadherin gamma (PCDHG) cluster on chromosome 5q31, which is crucial for neural circuit formation in the developing brain. Bisulfite pyrosequencing and targeted RNA sequencing showed that several genes of PCDHG subfamilies A and B are hypermethylated and transcriptionally downregulated in fetal DS cortex. Decreased PCDHG expression is expected to reduce dendrite arborization and growth in cortical neurons. Since constitutive hypermethylation of PCDHG and other genes affects multiple tissues, including blood, it may provide useful biomarkers for DS brain development and pharmacologic targets for therapeutic interventions.}, language = {en} } @article{BratengeierHolubyev2016, author = {Bratengeier, Klaus and Holubyev, Kostyantyn}, title = {Anisotropy of dose contributions-an instrument to upgrade real time IMRT and VMAT adaptation?}, series = {Medical Physics}, volume = {43}, journal = {Medical Physics}, number = {11}, doi = {10.1118/1.4963806}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-186833}, pages = {5826-5834}, year = {2016}, abstract = {Purpose: To suggest a definition of dose deposition anisotropy for the purpose of ad hoc adaptation of intensity modulated arc therapy (IMRT) and volumetric arc therapy (VMAT), particularly in the vicinity of important organs at risk (OAR), also for large deformations. Methods: Beam's-eye-view (BEV) based fluence warping is a standard adaptation method with disadvantages for strongly varying OAR shapes. 2-Step-adaptation overcomes these difficulties by a deeper analysis of the 3D properties of adaptation processes, but requires separate arcs for every OAR to spare, which makes it impractical for cases with multiple OARs. The authors aim to extend the 2-Step method to arbitrary intensity modulated plan by analyzing the anisotropy of dose contributions. Anisotropy was defined as a second term of Fourier transformation of gantry angle dependent dose contributions. For a cylindrical planning target volume (PTV) surrounding an OAR of varying diameter, the anisotropy and the dose-normalized anisotropy were analyzed for several scenarios of optimized fluence distributions. 2-Step adaptation to decreasing and increasing OAR diameter was performed, and compared to a usual fluence based adaptation method. For two clinical cases, prostate and neck, the VMAT was generated and the behavior of anisotropy was qualitatively explored for deformed organs at risk. \# Results: Dose contribution anisotropy in the PTV peaks around nearby OARs. The thickness of the "anisotropy wall" around OAR increases for increasing OAR radius, as also does the width of 2-Step dose saturating fluence peak adjacent to the OAR K. Bratengeier et al., "A comparison between 2-Step IMRT and conventional IMRT planning," Radiother. Oncol. 84, 298-306 (2007)]. Different optimized beam fluence profiles resulted in comparable radial dependence of normalized anisotropy. As predicted, even for patient cases, anisotropy was inflated even more than increasing diameters of OAR. Conclusions: For cylindrically symmetric cases, the dose distribution anisotropy defined in the present work implicitly contains adaptation-relevant information about 3D relationships between PTV and OAR and degree of OAR sparing. For more complex realistic cases, it shows the predicted behavior qualitatively. The authors claim to have found a first component for advancing a 2-Step adaptation to a universal adaptation algorithm based on the BEV projection of the dose anisotropy. Further planning studies to explore the potential of anisotropy for adaptation algorithms using phantoms and clinical cases of differing complexity will follow.}, language = {en} } @article{DotterweichSchlegelmilchKelleretal.2016, author = {Dotterweich, Julia and Schlegelmilch, Katrin and Keller, Alexander and Geyer, Beate and Schneider, Doris and Zeck, Sabine and Tower, Robert J.

Although several transcriptome analyses of myeloma patient-derived mesenchymal stem cells have displayed differences compared to their healthy counterparts, these analyses insufficiently reflect the signatures mediated by tumor cell contact, vary due to different methodologies, and lack results in lineage-committed precursors. To determine tumor cell contact-mediated changes on skeletal precursors, we performed transcriptome analyses of mesenchymal stem cells and osteogenic precursor cells cultured in contact with the myeloma cell line INA-6. Comparative analyses confirmed dysregulation of genes which code for known disease-relevant factors and additionally revealed upregulation of genes that are associated with plasma cell homing, adhesion, osteoclastogenesis, and angiogenesis. Osteoclast-derived coupling factors, a dysregulated adipogenic potential, and an imbalance in favor of anti-anabolic factors may play a role in the hampered osteoblast differentiation potential of mesenchymal stem cells. Angiopoietin-Like 4 (ANGPTL4) was selected from a list of differentially expressed genes as a myeloma cell contact-dependent target in skeletal precursor cells which warranted further functional analyses. Adhesion assays with full-length ANGPTL4-coated plates revealed a potential role of this protein in INA6 cell attachment.

In this study, we find that EGF stimulation specifically increases the transport efficiency of newly synthesized EGFRs from the endoplasmic reticulum to the plasma membrane. This coincides with an up-regulation of the inner coat protein complex II (COP II) components SEC23B, SEC24B, and SEC24D, which we show to be specifically required for EGFR transport. Up-regulation of these COP II components requires the transcriptional regulator RNF11, which localizes to early endosomes and appears additionally in the cell nucleus upon continuous EGF stimulation.

Previously, RES oxylipins have been shown massively to induce heat-shock-response (HSR) genes including HSP101 chaperones. Moreover, jasmonates have been reported to play a role in basal thermotolerance. We show that representative HSR marker genes are strongly induced by RES oxylipins through the four master regulator transcription factors HSFA1a, b, d, and e essential for short-term adaptation to heat stress in Arabidopsis. When compared with Arabidopsis seedlings treated at the optimal acclimation temperature of 37 A degrees C, the exogenous application of RES oxylipins at 20 A degrees C induced a much weaker induction of HSP101 at both the gene and protein expression levels which, however, was not sufficient to confer short-term acquired thermotolerance. Moreover, jasmonate-deficient mutant lines displayed a wild-type-like HSR and were not compromised in acquiring thermotolerance. Hence, the OPDA- and RES oxylipin-induced HSR is not sufficient to protect seedlings from severe heat stress but may help plants to cope better with stresses associated with protein unfolding by inducing a battery of chaperones in the absence of heat.}, language = {en} } @article{JoensuuAltimirHakolaetal.2016, author = {Joensuu, Johanna and Altimir, Nuria and Hakola, Hannele and Rost{\´a}s, Michael and Raivonen, Maarit and Vestenius, Mika and Aaltonen, Hermanni and Riederer, Markus and B{\"a}ck, Jaana}, title = {Role of needle surface waxes in dynamic exchange of mono- and sesquiterpenes}, series = {Atmospheric Chemistry and Physics}, volume = {16}, journal = {Atmospheric Chemistry and Physics}, number = {12}, doi = {10.5194/acp-2015-1024}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-171324}, pages = {7813-7823}, year = {2016}, abstract = {Biogenic volatile organic compounds (BVOCs) produced by plants have a major role in atmospheric chemistry.

Both emissions and wax extracts were clearly dominated by monoterpenes, but the proportion of sesquiterpenes was higher in the wax extracts. There were also differences in the terpene spectra of the emissions and the wax extracts. The results, therefore, support the existence of BVOC associated to the epicuticular waxes.

Ubiquitin-conjugating (E2) enzymes, such as Ube2S, catalyze the formation of an isopeptide linkage between the C-terminus of a "donor" ubiquitin and a primary amino group of an "acceptor" ubiquitin molecule. This reaction involves an intermediate, in which the C-terminus of the donor ubiquitin is thioester-bound to the active site cysteine of the E2 and a functionally important interface is formed between the two proteins. A docked model of a Ube2S-donor ubiquitin complex was generated previously, based on chemical shift mapping by NMR, and predicted contacts were validated in functional studies. We now present the crystal structure of a covalent Ube2S-ubiquitin complex. The structure contains an interface between Ube2S and ubiquitin in trans that resembles the earlier model in general terms, but differs in detail. The crystallographic interface is more hydrophobic than the earlier model and is stable in molecular dynamics (MD) simulations. Remarkably, the docked Ube2S-donor complex converges readily to the configuration seen in the crystal structure in 3 out of 8 MD trajectories. Since the crystallographic interface is fully consistent with mutational effects, this indicates that the structure provides an energetically favorable representation of the functionally critical Ube2S-donor interface.}, language = {en} } @article{BahnikStrack2016, author = {Bahn{\´i}k, Štěp{\´a}n and Strack, Fritz}, title = {Overlap of accessible information undermines the anchoring effect}, series = {Judgment and Decision Making}, volume = {11}, journal = {Judgment and Decision Making}, number = {1}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-169287}, pages = {92-98}, year = {2016}, abstract = {According to the Selective Accessibility Model of anchoring, the comparison question in the standard anchoring paradigm activates information that is congruent with an anchor.

Here, we investigated the molecular regulation of endothelial permeability by the vascular endothelial growth factor (VEGF) and both tight and adherens junction proteins (VE-cadherin and claudin 5) with regards to the tumor biology of different ovarian cancer types. Methods Serum and ascites samples before and after surgery, as well as peritoneal biopsies of 68 ovarian cancer patients and 20 healthy controls were collected. In serum and ascites VEGF protein was measured by ELISA. In peritoneal biopsies co-localization of VE-cadherin and claudin 5 was investigated using immunohistochemical dual staining. In addition, the gene expression of VE-cadherin and claudin 5 was quantified by Real-time PCR. Differences in VEGF levels, VE-cadherin and claudin 5 gene expression were analyzed in relation to various tumor characteristics (tumor stage, grading, histological subtypes, resection status after surgery) and then compared to controls. Furthermore, human primary ovarian cancer cells were co-cultured with human umbilical vein endothelial cells (HUVEC) and changes in VE-cadherin and claudin 5 were investigated after VEGF inhibition. Results VEGF was significantly increased in tumor patients in comparison to controls and accumulates in ascites. The highest VEGF levels were found in patients diagnosed with advanced tumor stages, with tumors of poor differentiation, or in the group of solid / cystic-solid tumors. Patients with residual tumor after operation showed significantly higher levels of VEGF both before and after surgery as compared to tumor-free resected patients. Results of an immunohistochemical double-staining experiment indicated co-localization of VE-cadherin and claudin 5 in the peritoneal vasculature. Compared to controls, expression of VE-cadherin and claudin 5 was significantly suppressed in peritoneal vessels of tumor patients, but there were no significant differences regarding VE-cadherin and claudin 5 expression in relation to different tumor characteristics. A significant positive correlation was found between VE-cadherin and claudin 5 expression. VEGF inhibition in vitro was associated with significant increase in VE-cadherin and claudin 5. Conclusions Our results indicate that increased peritoneal permeability in ovarian cancer is due to down-regulation of adhesion proteins via tumor derived VEGF. Advanced ovarian cancer with aggressive tumor biology may be associated with early dysregulation of vascular permeability leading to ascites.

Operation time, blood loss, and intraoperative complications have not been more frequent in the elderly, whereas hospital stay was significantly longer in ≥70 y/o patients. Regarding postoperative complications, we noticed that ≥70 y/o patients had an almost threefold risk to develop mild early postoperative complications compared to younger patients (OR: 2.86; 95\% CI: 1.76-4.66). On the contrary, major complications were not more frequent. No case of life-threatening complication or the need for blood transfusion was reported. Conclusion. After urogynecological procedures, septuagenarians and older patients are more likely to develop mild postoperative complications but not more intraoperative or severe postoperative complications compared to younger patients.}, language = {en} } @article{IsaiasTrujilloSummersetal.2016, author = {Isaias, Ioannis U. and Trujillo, Paula and Summers, Paul and Marotta, Giorgio and Mainardi, Luca and Pezzoli, Gianni and Zecca, Luigi and Costa, Antonella}, title = {Neuromelanin Imaging and Dopaminergic Loss in Parkinson's Disease}, series = {Frontiers in Aging Neuroscience}, volume = {8}, journal = {Frontiers in Aging Neuroscience}, number = {196}, doi = {10.3389/fnagi.2016.00196}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-164046}, year = {2016}, abstract = {Parkinson's disease (PD) is a progressive neurodegenerative disorder in which the major pathologic substrate is a loss of dopaminergic neurons from the substantia nigra. Our main objective was to determine the correspondence between changes in the substantia nigra, evident in neuromelanin and iron sensitive magnetic resonance imaging (MRI), and dopaminergic striatal innervation loss in patients with PD. Eighteen patients and 18 healthy control subjects were included in the study. Using neuromelanin-MRI, we measured the volume of the substantia nigra and the contrast-to-noise-ratio between substantia nigra and a background region. The apparent transverse relaxation rate and magnetic susceptibility of the substantia nigra were calculated from dual-echo MRI. Striatal dopaminergic innervation was measured as density of dopamine transporter (DAT) by means of single-photon emission computed tomography and [123I] N-ω-fluoropropyl-2b-carbomethoxy-3b-(4-iodophenyl) tropane. Patients showed a reduced volume of the substantia nigra and contrast-to-noise-ratio and both positively correlated with the corresponding striatal DAT density. The apparent transverse relaxation rate and magnetic susceptibility values of the substantia nigra did not differ between patients and healthy controls. The best predictor of DAT reduction was the volume of the substantia nigra. Clinical and imaging correlations were also investigated for the locus coeruleus. Our results suggest that neuromelanin-MRI can be used for quantifying substantia nigra pathology in PD where it closely correlates with dopaminergic striatal innervation loss. Longitudinal studies should further explore the role of Neuromelanin-MRI as an imaging biomarker of PD, especially for subjects at risk of developing the disease.}, language = {en} } @phdthesis{Lorenzin2016, author = {Lorenzin, Francesca}, title = {Regulation of transcription by MYC - DNA binding and target genes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-150766}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2016}, abstract = {MYC is a transcription factor, whose expression is elevated or deregulated in many human cancers (up to 70\%) and is often associated with aggressive and poorly differentiated tumors. Although MYC is extensively studied, discrepancies have emerged about how this transcription factor works. In primary lymphocytes, MYC promotes transcriptional amplification of virtually all genes with an open promoter, whereas in tumor cells MYC regulates specific sets of genes that have significant prognostic value. Furthermore, the set of target genes that distinguish MYC's physiological function from the pathological/oncogenic one, whether it exists or not, has not been fully understood yet. In this study, it could be shown that MYC protein levels within a cell and promoter affinity (determined by E-box presence or interaction with other proteins) of target genes toward MYC are important factors that influence MYC activity. At low levels, MYC can amplify a certain transcriptional program, which includes high affinity binding sites, whereas at high levels MYC leads to the specific up- and down regulation of genes with low affinity. Moreover, the promoter affinity characterizes different sets of target genes which can be distinguished in the physiological or oncogenic MYC signatures. MYC-mediated repression requires higher MYC levels than activation and formation of a complex with MIZ1 is necessary for inhibiting expression of a subset of MYC target genes.}, subject = {MYC}, language = {en} } @phdthesis{Brockmann2016, author = {Brockmann, Nicolas}, title = {Kompositschichten aus dealuminiertem Zeolith Y und Hybridpolymeren auf Basis von Bis(triethoxysilyl)ethan}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-150817}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2016}, abstract = {Die vorliegende Arbeit besch{\"a}ftigt sich mit Kompositschichten aus Zeolithen und Hybridpolymeren, die mittels des Sol-Gel-Prozesses aus Alkyltrialkoxysilanen hergestellt werden.

In dieser experimentellen Studie wurde die Auswirkung verschiedener Oszillationsfrequenzen bei der HFOV auf die CO2-Elimination mit und ohne die Hinzunahme einer arterioven{\"o}sen extrakorporalen Lungenassistenz (avECLA) im Großtier-ARDS-Modell untersucht. Unsere Hypothese: die Verwendung hoher Oszillationsfrequenzen und damit die Minimierung des Tidalvolumens erfordert die Kombination einer HFOV mit einer avECLA, um Normokapnie zu erhalten oder wiederherzustellen. Methodik: Hierzu wurden acht gesunde Pietrain-Schweine (56,5 ± 4,4 kg) narkotisiert und intubiert und anschließend mittels pulmonaler Lavage ein schweres iatrogenes ARDS herbeigef{\"u}hrt. Nach einst{\"u}ndiger Stabilisierungsphase (PaO2 durchgehend < 80 mmHg) erfolgte ein Recruitment-Man{\"o}ver und die Einstellung des mittleren Atemwegsdrucks auf 3 cmH2O {\"u}ber dem zuvor bestimmten unteren Inflektionspunkt. Anschließend wurden die Tiere der HFOV zugef{\"u}hrt, randomisiert und mit entweder auf- oder absteigenden Oszillationsfrequenzen jeweils 30 Minuten mit und ohne Hinzunahme der avECLA beatmet. Ergebnisse: Ab Oszillationsfrequenzen von 9 Hz entwickelten die Versuchstiere ohne die Hinzunahme einer avECLA z{\"u}gig eine Hyperkapnie, welcher nur durch die Hinzunahme der avECLA entgegengewirkt werden konnte. Durch das Recruitment-Man{\"o}ver und die Einstellung des mittleren Atemwegsdrucks auf 3 cmH2O {\"u}ber dem unteren Inflektionspunkt konnte die Oxygenierung dauerhaft signifikant verbessert werden (p<0.05). Die Ergebnisse der beiden Gruppen (auf- vs. absteigende Oszillationsfrequenzen) unterschieden sich dabei nicht voneinander. Zusammenfassung: Bei der Hochfrequenzoszillationsbeatmung (HFOV) konnte Normokapnie bei Oszillationsfrequenzen von 9 - 15 Hz nur durch die Kombination mit einer arterioven{\"o}sen extrakorporalen Lungenassistenz (avECLA) aufrecht erhalten werden. Zus{\"a}tzlich konnte nach dem Recruitment-Man{\"o}ver und der Einstellung des mittleren Atemwegsdrucks auf 3 cmH2O {\"u}ber dem unteren Inflektionspunkt auch noch bei sehr hohen Oszillationsfrequenzen eine dauerhafte, signifikante Verbesserung der Oxygenierung verzeichnet werden. Somit demaskiert die avECLA das lungenprotektive Potential der HFOV: die Minimierung der applizierten Tidalvolumina begrenzt nicht nur eine alveol{\"a}re {\"U}berbl{\"a}hung und damit Volutraumata, die Applikation h{\"o}herer mittlerer Atemwegsdr{\"u}cke erm{\"o}glicht dar{\"u}ber hinaus ein pulmonales Recruitment und sch{\"u}tzt die Lunge damit vor Atelekttraumata.}, subject = {ARDS}, language = {de} } @incollection{Schmitz2016, author = {Schmitz, Barbara}, title = {Space, Borders and Boundaries in the Letter of Aristeas}, series = {Borders : Terminologies, Ideologies, and Performances}, booktitle = {Borders : Terminologies, Ideologies, and Performances}, publisher = {Mohr Siebeck}, address = {T{\"u}bingen}, isbn = {978-3-16-154375-3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-151285}, publisher = {Universit{\"a}t W{\"u}rzburg}, pages = {142-154}, year = {2016}, abstract = {No abstract available.}, subject = {Aristeas, Epistolographus : Ad Philocratem}, language = {en} } @article{Schmitz2016, author = {Schmitz, Barbara}, title = {Tradition und (Er)Neuerung.

Bee foraging dynamics and fitness depend on the availability of resources in the surrounding landscape, but how precisely landscape related resource differences affect bee foraging patterns remains unclear. To investigate how landscape and its interaction with season and weather drive foraging and resource intake in social bees, we experimentally compared foraging activity, the allocation of foragers to different resources (pollen, nectar, and resin) and overall resource intake in the Australian stingless bee Tetragonula carbonaria (Apidae, Meliponini). Bee colonies were monitored in different seasons over two years. We compared foraging patterns and resource intake between the bees' natural habitat (forests) and two landscapes differently altered by humans (suburban gardens and agricultural macadamia plantations). We found foraging activity as well as pollen and nectar forager numbers to be highest in suburban gardens, intermediate in forests and low in plantations. Foraging patterns further differed between seasons, but seasonal variations strongly differed between landscapes. Sugar and pollen intake was low in plantations, but contrary with our predictions, it was even higher in gardens than in forests. In contrast, resin intake was similar across landscapes. Consequently, differences in resource availability between natural and altered landscapes strongly affect foraging patterns and thus resource intake in social bees. While agricultural monocultures largely reduce foraging success, suburban gardens can increase resource intake well above rates found in natural habitats of bees, indicating that human activities can both decrease and increase the availability of resources in a landscape and thus reduce or enhance bee fitness.}, language = {en} } @article{Koch2016, author = {Koch, Christian}, title = {Et amen.

We performed a prospective analysis of hs-TNT as a biomarker for myocardial changes in Fabry patients and a retrospective longitudinal follow-up study to assess longitudinal hs-TNT changes relative to fibrosis and cardiomyopathy progression. Methods and Results For the prospective analysis, hs-TNT from 75 consecutive patients with genetically confirmed Fabry disease was analyzed relative to typical Fabry-associated echocardiographic findings and total myocardial fibrosis as measured by late gadolinium enhancement (LE) on magnetic resonance imaging. Longitudinal data (3.9±2.0 years), including hs-TNT, LE, and echocardiographic findings from 58 Fabry patients, were retrospectively collected. Hs-TNT level positively correlated with LE (linear correlation coefficient, 0.72; odds ratio, 32.81 [95\% CI, 3.56-302.59]; P=0.002); patients with elevated baseline hs-TNT (>14 ng/L) showed significantly increased LE (median: baseline, 1.9 [1.1-3.3] \%; follow-up, 3.2 [2.3-4.9] \%; P<0.001) and slightly elevated hs-TNT (baseline, 44.7 [30.1-65.3] ng/L; follow-up, 49.1 [27.6-69.5] ng/L; P=0.116) during follow-up. Left ventricular wall thickness and EF of patients with elevated hs-TNT were decreased during follow-up, indicating potential cardiomyopathy progression.
