The development of complex analytical instruments, in particular in fluorescence microscopy, has played a decisive role in this. Scientist can now rely on a wide range of imaging techniques that offer different advantages in terms of optical resolution, recording speed or living cell compatibility. With the help of these modern microscopy techniques, multi-protein complexes can be resolved, membrane receptors can be counted, cellular pathways analysed or the internalisation of receptors can be tracked. However, there is currently no universal technique for comprehensive experiment execution that includes dynamic process capture and super resolution imaging on the same target object. In this work, I built a microscope that combines two complementary imaging techniques and enables correlative experiments in living and fixed cells. With an image scanning based laser spot confocal microscope, fast dynamics in several colors with low photodamage of the cells can be recorded. This novel system also has an improved resolution of 170 nm and was thoroughly characterized in this work. The complementary technique is based on single molecule localization microscopy, which can achieve a structural resolution down to 20-30 nm. Furthermore I implemented a microfluidic pump that allows direct interaction with the sample placed on the microscope. Numerous processes such as living cell staining, living cell fixation, immunostaining and buffer exchange can be observed and performed directly on the same cell. Thus, dynamic processes of a cell can be frozen and the structures of interest can be stained and analysed with high-resolution microscopy. Furthermore, I have equipped the detection path of the single molecule technique with an adaptive optical element. With the help of a deformable mirror, imaging functions can be shaped and information on the 3D position of the individual molecules can be extracted.}, subject = {Einzelmolek{\"u}lmikroskopie}, language = {en} } @phdthesis{Hagmann2020, author = {Hagmann, Hanns Antony}, title = {The impact of the CRISPR/Cas system on the interaction of Neisseria meningitidis with human host cells}, doi = {10.25972/OPUS-19949}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-199490}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {Neisseria meningitidis, a commensal β-proteobacterium residing exclusively in the human nasopharynx, is a leading cause of sepsis and epidemic meningitis worldwide. While comparative genome analysis was able to define hyperinvasive lineages that are responsible for most of the cases of invasive meningococcal disease (IMD), the genetic basis of their virulence remains unclear. Recent studies demonstrate that the type II C CRISPR/Cas system of meningococci is associated with carriage and less invasive lineages. CRISPR/Cas, an adaptive defence system against foreign DNA, was shown to be involved in gene regulation in Francisella novicida. This study shows that knockout strains of N. meningitidis lacking the Cas9 protein are impaired in the adhesion to human nasopharyngeal cells in a strain-dependant manner, which constitutes a central step in the pathogenesis of IMD. Consequently, this study indicates that the meningococcal CRISPR/Cas system fulfils functions beyond the defence of foreign DNA and is involved in the regulation of meningococcal virulence.}, subject = {CRISPR/Cas-Methode}, language = {en} } @phdthesis{Reichenbach2020, author = {Reichenbach, Juliane Renate}, title = {Paternal age effects on sperm DNA methylation and its impact on the next generation}, doi = {10.25972/OPUS-19980}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-199805}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2020}, abstract = {The effect of late parenthood on the offspring´s physical and mental health status has recently become an increasingly important topic of discussion. Studies on neurodevelopmental disorders in children of older parents (Naserbakht et al., 2011) outline the negative consequences of aging fathers as unpredictable compared to the better-understood unfavorable maternal influences (Cedars et al. 2015). This may be due to the fact that lifelong production of male gametes becomes more susceptible to error, not only for somatic mutations. Non-genomic mechanisms such as epigenetic methylation also alter DNA dynamically throughout life (Jones et al., 2015) and influence the aging human sperm DNA (Jenkins et al., 2014). These methylation changes may be transmitted to the next generation via epigenetic inheritance mechanisms (Milekic et al., 2015), which may negatively impact the sensitive epigenetic regulation of cell differentiation in the embryonic period (Curley et al., 2011; Spiers et al., 2015). Accordingly, Nardone et al. (2014) reported several hypomethylated regions in autistic patients, illustrating potential epigenetic influences on the multifactorial pathogenesis of neuropsychiatric disorders. In the present study, the methylation status of five gene regions in the sperm DNA of males of different ages was analyzed by two techniques - pyrosequencing and deep bisulfite sequencing. Two gene regions, FOXK1 and DMPK, showed a highly significant age-related methylation loss and FOXK1 a reduced methylation variation at the level of single alleles. In addition, the examined gene region of FOXK1 showed significant methylation changes in the fetal cord blood DNA of the respective offspring of the sperm donor. This fact suggests a transfer of age-related methylation loss to the next generation. Interestingly, a methylation analysis at the level of single alleles showed that the methylation loss was inherited exclusively by the father. FOXK1 is a transcription factor that plays an important role in the epigenetic regulation of the cell cycle during embryonic neuronal development (Huang et al., 2004; Wijchers et al., 2006). For this reason, the methylation status of FOXK1 in the blood of autistic patients and an age- and sex-matched control group was investigated. While both groups showed age-associated FOXK1 methylation loss, a faster dynamics of methylation change was observed in the autistic group. Although further studies are needed to uncover inheritance mechanisms of epigenetic information, the present results show an evident influence of age-related methylation changes on offspring. When advising future fathers, it is important to consider how the paternal epigenome is altered by aging and can have a negative impact on the developing embryo.}, subject = {Epigenetik}, language = {en} } @article{BlaettnerDasPaprotkaetal.2016, author = {Bl{\"a}ttner, Sebastian and Das, Sudip and Paprotka, Kerstin and Eilers, Ursula and Krischke, Markus and Kretschmer, Dorothee and Remmele, Christian W. and Dittrich, Marcus and M{\"u}ller, Tobias and Schuelein-Voelk, Christina and Hertlein, Tobias and Mueller, Martin J. and Huettel, Bruno and Reinhardt, Richard and Ohlsen, Knut and Rudel, Thomas and Fraunholz, Martin J.}, title = {Staphylococcus aureus Exploits a Non-ribosomal Cyclic Dipeptide to Modulate Survival within Epithelial Cells and Phagocytes}, series = {PLoS Pathogens}, volume = {12}, journal = {PLoS Pathogens}, number = {9}, doi = {10.1371/journal.ppat.1005857}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-180380}, year = {2016}, abstract = {Community-acquired (CA) Staphylococcus aureus cause various diseases even in healthy individuals. 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.

Based on a locally modified energy gap between two Born-Oppenheimer electronic states as a collective variable, multistate metadynamics trajectories are driven toward an intersection point starting from an arbitrary ground state geometry and are subsequently forced to explore the conical intersection seam landscape. For this purpose, an additional collective variable capable of distinguishing structures within the seam needs to be defined and an additional bias is introduced into the off-diagonal elements of an extended (multistate) electronic Hamiltonian. We demonstrate the performance of the algorithm on the examples of the 1,3-butadiene, benzene, and 9H-adenine molecules, where multiple minimum energy crossing points could be systematically located using the Wiener number or Cremer-Pople parameters as collective variables. Finally, with the example of 9H-adenine, we show that the multistate metadynamics potential can be used to obtain a global picture of a conical intersection seam. Our method can be straightforwardly connected with any ab initio or semiempirical electronic structure theory that provides energies and gradients of the respective electronic states and can serve for systematic elucidation of the role of conical intersections in the photophysics and photochemistry of complex molecular systems, thus complementing nonadiabatic dynamics simulations.}, language = {en} } @article{HansmannHeinzmannWrenzyckietal.2010, author = {Hansmann, T. and Heinzmann, J. and Wrenzycki, C. and Zechner, U. and Niemann, H. and Haaf, T.}, title = {Characterization of Differentially Methylated Regions in 3 Bovine Imprinted Genes: A Model for Studying Human Germ-Cell and Embryo Development}, series = {Cytogenetic and Genome Research}, volume = {132}, journal = {Cytogenetic and Genome Research}, number = {4}, issn = {1424-8581}, doi = {10.1159/000322627}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-199051}, pages = {239-247}, year = {2010}, abstract = {Correct imprinting is crucial for normal fetal and placental development in mammals. Experimental evidence in animal models and epidemiological studies in humans suggest that assisted reproductive technologies (ARTs) can interfere with imprinted gene regulation in gametogenesis and early embryogenesis. Bos taurus is an agriculturally important species in which ARTs are commonly employed. Because this species exhibits a similar preimplantation development and gestation length as humans, it is increasingly being used as a model for human germ-cell and embryo development. However, in contrast to humans and mice, there is relatively little information on bovine imprinted genes. Here, we characterized the bovine intergenic IGF2-H19 imprinting control region (ICR) spanning approximately 3 kb. We identified a 300-bp differentially methylated region (DMR) approximately 6 kb upstream of the H19 promoter, containing a CpG island with CTCF-binding site and high sequence similarity with the human intergenic ICR. Additional differentially methylated CpG islands lie -6 kb to -3 kb upstream of the promoter, however these are less conserved. Both classical bisulfite sequencing and bisulfite pyrosequencing demonstrated complete methylation of the IGF2-H19 ICR in sperm, complete demethylation in parthenogenetic embryos having only the female genome, and differential methylation in placental and somatic tissues. In addition, we established pyrosequencing assays for the previously reported bovine SNRPN and PEG3 DMRs. The observed methylation patterns were consistent with genomic imprinting in all analyzed tissues/cell types.

This study aimed to identify predictors of altered FXI and FXII levels and to determine whether there are differences in the levels of these coagulation factors between acute cerebrovascular events and chronic cerebrovascular disease (CCD). Methods: In this case-control study, 116 patients with acute ischemic stroke (AIS) or transitory ischemic attack (TIA), 117 patients with CCD, and 104 healthy volunteers (HVs) were enrolled between 2010 and 2013 at our University hospital. Blood sampling was undertaken once in the CCD and HV groups and on days 0, 1, and 3 after stroke onset in patients with AIS or TIA. Correlations between serum FXI and FXII levels and demographic and clinical parameters were tested by linear regression and analysis of variance. Results: The mean age of AIS/TIA patients was 70 ± 12. Baseline clinical severity measured with NIHSS and Barthel Index was 4.8 ± 6.0 and 74 ± 30, respectively. More than half of the patients had an AIS (58\%). FXI levels were significantly correlated with different leukocyte subsets (p < 0.05). In contrast, FXII serum levels showed no significant correlation (p > 0.1). Neither FXI nor FXII levels correlated with CRP (p > 0.2). FXII levels were significantly higher in patients with CCD compared with those with AIS/TIA (mean ± SD 106 ± 26\% vs. 97 ± 24\%; univariate analysis: p < 0.05); these differences did not reach significance in multivariate analysis adjusted for sex and age. FXI levels did not differ significantly between study groups. Sex and age were significantly associated with FXI and/or FXII levels in patients with AIS/TIA (p < 0.05). In contrast, no statistical significant influence was found for treatment modality (thrombolysis or not), pre-treatment with platelet inhibitors, and severity of stroke. Conclusions: In this study, there was no differential regulation of FXI and FXII levels between disease subtypes but biomarker levels were associated with patient and clinical characteristics.

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.

In order to establish an optimal replicative niche, the pathogen extensively interferes with the physiology of the host cell. Chlamydia switches in its complex developmental cycle between the infectious non-replicative elementary bodies (EBs) and the non-infectious replicative reticulate bodies (RBs). The transformation to RBs, shortly after entering a host cell, is a crucial process in infection to start chlamydial replication. Currently it is unknown how the transition from EBs to RBs is initiated. In this thesis, we could show that, in an axenic media approach, L glutamine uptake by the pathogen is crucial to initiate the EB to RB transition. L-glutamine is converted to amino acids which are used by the bacteria to synthesize peptidoglycan. Peptidoglycan inturn is believed to function in separating dividing Chlamydia. The glutamine metabolism is reprogrammed in infected cells in a c-Myc-dependent manner, in order to accomplish the increased requirement for L-glutamine. Upon a chlamydial infection, the proto-oncogene c-Myc gets upregulated to promote host cell glutaminolysis via glutaminase GLS1 and the L-glutamine transporter SLC1A5/ASCT2. Interference with this metabolic reprogramming leads to limited growth of C. trachomatis. Besides the active infection, Chlamydia can persist over a long period of time within the host cell whereby chronic and recurrent infections establish. C. trachomatis acquire a persistent state during an immune attack in response to elevated interferon-γ (IFN-γ) levels. It has been shown that IFN-γ activates the catabolic depletion of L-tryptophan via indoleamine 2,3-dioxygenase (IDO), resulting in the formation of non-infectious atypical chlamydial forms. In this thesis, we could show that IFN-γ depletes the key metabolic regulator c-Myc, which has been demonstrated to be a prerequisite for chlamydial development and growth, in a STAT1-dependent manner. Moreover, metabolic analyses revealed that the pathogen de routs the host cell TCA cycle to enrich pyrimidine biosynthesis. Supplementing pyrimidines or a-ketoglutarate helps the bacteria to partially overcome the persistent state. Together, the results indicate a central role of c-Myc induced host glutamine metabolism reprogramming and L-glutamine for the development of C. trachomatis, which may provide a basis for anti-infectious strategies. Furthermore, they challenge the longstanding hypothesis of L-tryptophan shortage as the sole reason for IFN-γ induced persistence and suggest a pivotal role of c-Myc in the control of the C. trachomatis dormancy.}, language = {en} } @article{KotsevaDeBackerDeBacqueretal.2019, author = {Kotseva, Kornelia and De Backer, Guy and De Bacquer, Dirk and Ryd{\´e}n, Lars and Hoes, Arno and Grobbee, Diederick and Maggioni, Aldo and Marques-Vidal, Pedro and Jennings, Catriona and Abreu, Ana and Aguiar, Carlos and Badariene, Jolita and Bruthans, Jan and Castro Conde, Almudena and Cifkova, Renata and Crowley, Jim and Davletov, Kairat and Deckers, Jaap and De Smedt, Delphine and De Sutter, Johan and Dilic, Mirza and Dolzhenko, Marina and Dzerve, Vilnis and Erglis, Andrejs and Fras, Zlatko and Gaita, Dan and Gotcheva, Nina and Heuschmann, Peter and Hasan-Ali, Hosam and Jankowski, Piotr and Lalic, Nebojsa and Lehto, Seppo and Lovic, Dragan and Mancas, Silvia and Mellbin, Linda and Milicic, Davor and Mirrakhimov, Erkin and Oganov, Rafael and Pogosova, Nana and Reiner, Zeljko and St{\"o}erk, Stefan and Tokg{\"o}zoğlu, L{\^a}le and Tsioufis, Costas and Vulic, Dusko and Wood, David}, title = {Lifestyle and impact on cardiovascular risk factor control in coronary patients across 27 countries: Results from the European Society of Cardiology ESC-EORP EUROASPIRE V registry}, series = {European Journal of Preventive Cardiology}, volume = {26}, journal = {European Journal of Preventive Cardiology}, number = {8}, organization = {EUROASPIRE Investigators}, issn = {2047-4873}, doi = {10.1177/2047487318825350}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-205526}, pages = {824-835}, year = {2019}, abstract = {Aims The aim of this study was to determine whether the Joint European Societies guidelines on secondary cardiovascular prevention are followed in everyday practice.

Quantifying such extinctions and investigating long-term consequences of perturbations has proven challenging, because perturbations are not isolated and occur across various spatial and temporal scales, from local habitat losses to global warming. Additionally, the relative importance of eco-evolutionary processes varies across scales, because levels of ecological organization, i.e. individuals, (meta)populations and (meta)communities, respond hierarchically to perturbations. To summarize our current knowledge of the scales and mechanisms influencing extinction debts, we reviewed recent empirical, theoretical and methodological studies addressing either the spatio-temporal scales of extinction debts or the eco-evolutionary mechanisms delaying extinctions. Extinction debts were detected across a range of ecosystems and taxonomic groups, with estimates ranging from 9 to 90\% of current species richness. The duration over which debts have been sustained varies from 5 to 570 yr, and projections of the total period required to settle a debt can extend to 1000 yr. Reported causes of delayed extinctions are 1) life-history traits that prolong individual survival, and 2) population and metapopulation dynamics that maintain populations under deteriorated conditions. Other potential factors that may extend survival time such as microevolutionary dynamics, or delayed extinctions of interaction partners, have rarely been analyzed. Therefore, we propose a roadmap for future research with three key avenues: 1) the microevolutionary dynamics of extinction processes, 2) the disjunctive loss of interacting species and 3) the impact of multiple regimes of perturbation on the payment of debts. For their ability to integrate processes occurring at different levels of ecological organization, we highlight mechanistic simulation models as tools to address these knowledge gaps and to deepen our understanding of extinction dynamics.}, language = {en} } @article{AtaeeMaghsoudiLatifietal.2019, author = {Ataee, Mohammad Sadegh and Maghsoudi, Yasser and Latifi, Hooman and Fadaie, Farhad}, title = {Improving estimation accuracy of growing stock by multi-frequency SAR and multi-spectral data over Iran's heterogeneously-structured broadleaf Hyrcanian forests}, series = {Forests}, volume = {10}, journal = {Forests}, number = {8}, issn = {1999-4907}, doi = {10.3390/f10080641}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-197212}, year = {2019}, abstract = {Via providing various ecosystem services, the old-growth Hyrcanian forests play a crucial role in the environment and anthropogenic aspects of Iran and beyond. The amount of growing stock volume (GSV) is a forest biophysical parameter with great importance in issues like economy, environmental protection, and adaptation to climate change. Thus, accurate and unbiased estimation of GSV is also crucial to be pursued across the Hyrcanian. Our goal was to investigate the potential of ALOS-2 and Sentinel-1's polarimetric features in combination with Sentinel-2 multi-spectral features for the GSV estimation in a portion of heterogeneously-structured and mountainous Hyrcanian forests. We used five different kernels by the support vector regression (nu-SVR) for the GSV estimation. Because each kernel differently models the parameters, we separately selected features for each kernel by a binary genetic algorithm (GA). We simultaneously optimized R\(^2\) and RMSE in a suggested GA fitness function. We calculated R\(^2\), RMSE to evaluate the models. We additionally calculated the standard deviation of validation metrics to estimate the model's stability. Also for models over-fitting or under-fitting analysis, we used mean difference (MD) index. The results suggested the use of polynomial kernel as the final model. Despite multiple methodical challenges raised from the composition and structure of the study site, we conclude that the combined use of polarimetric features (both dual and full) with spectral bands and indices can improve the GSV estimation over mixed broadleaf forests. This was partially supported by the use of proposed evaluation criterion within the GA, which helped to avoid the curse of dimensionality for the applied SVR and lowest over estimation or under estimation.}, language = {en} } @unpublished{LisinetskayaMitric2019, author = {Lisinetskaya, Polina G. and Mitric, Roland}, title = {Collective Response in DNA-Stabilized Silver Cluster Assemblies from First-Principles Simulations}, series = {The Journal of Physical Chemistry Letters}, journal = {The Journal of Physical Chemistry Letters}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-198729}, year = {2019}, abstract = {We investigate fluorescence resonant energy transfer and concurrent electron dynamics in a pair of DNA-stabilized silver clusters.
