They are among the brightest objects in the very high energy (VHE) gamma ray regime (>100 GeV). Their emitted gamma-ray fluxes are extremely variable, with changing activity levels on timescales between minutes, months, and even years. Several questions are part of the current research, such as the question of the emission regions or the engine of the AGN and the particle acceleration. A dedicated longterm monitoring program is necessary to investigate the properties of blazars in detail. A densely sampled and unbiased light curve allows for observation of both high and low states of the sources, and the combination with multi-wavelength observation could contribute to the answer of several questions mentioned above. FACT (First G-APD Cherenkov Telescope) is the first operational telescope using silicon photomultiplier (SiPM, also known as Geigermode—Avalanche Photo Diode, G-APD) as photon detectors. SiPM have a very homogenous and stable longterm performance, and allow operation even during full moon without any filter, leading to a maximal duty cycle for an Imaging Air Cherenkov Telescope (IACT). Hence, FACT is an ideal device for such a longterm monitoring of bright blazars. A small set of sources (e.g., Markarian 421, Markarian 501, 1ES 1959+650, and 1ES 2344+51.4) is currently being monitored. In this contribution, the FACT telescope and the concept of longterm monitoring of bright blazars will be introduced.

Signals which induce activation, migration and differentiation of these cells are largely unknown. Here we have isolated rat ventricular EPDC and rat/human ASC and performed genetic and proteomic profiling. EPDC and ASC expressed epicardial/mesenchymal markers (WT-1, Tbx18, CD73,CD90, CD44, CD105), cardiac markers (Gata4, Tbx5, troponin T) and also contained phosphocreatine. We used cell surface biotinylation to isolate plasma membrane proteins of rEPDC and hASC, Nano-liquid chromatography with subsequent mass spectrometry and bioinformatics analysis identified 396 rat and 239 human plasma membrane proteins with 149 overlapping proteins. Functional GO-term analysis revealed several significantly enriched categories related to extracellular matrix (ECM), cell migration/differentiation, immunology or angiogenesis. We identified receptors for ephrin and growth factors (IGF, PDGF, EGF, anthrax toxin) known to be involved in cardiac repair and regeneration. Functional category enrichment identified clusters around integrins, PI3K/Akt-signaling and various cardiomyopathies. Our study indicates that EPDC and ASC have a similar molecular phenotype related to cardiac healing/regeneration. The cell surface proteome repository will help to further unravel the molecular details of their cardio-regenerative potential and their role in cardiac diseases.}, language = {en} } @phdthesis{Terveer2017, author = {Terveer, Nils}, title = {Springs and Parachutes - Development and Characterization of Novel Formulations for Poorly Water-Soluble Drugs}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-154311}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2017}, abstract = {Successful formulation development of novel, particularly organic APIs of low molecular weight as candidates for ground-breaking pharmaceutical products is a major challenge for the pharmaceutical industry because of the poor aqueous solubility of most of these compounds. The hit identification strategies of drug development in use today apply high throughput screening techniques for the investigation of thousands of substances. This approach led to a systematical increase in molecular weight and lipophilicity and a decrease of water solubility of lead compounds reaching market access. The high lipophilicity causes an excellent permeability of the compounds which favours the absorption process from the small intestine, but it causes a decrease of water-solubility. It becomes evident that an adequate aqueous solubility is necessary for absorption of the API from the gastrointestinal fluids into the systemic circulation and hence for efficacy of the pharmaceutical product. Only an dissolved API is getting absorbed and becomes efficacious. The precipitated proportion is resigned directly. Therefore, the development of an individual formulation aligning the physicochemical characteristics is necessary for every API to produce supersaturated solutions in the small intestine and to reach an adequate bioavailability after absorption into the systemic circulation. In this thesis a specific formulation development was investigated for two exemplary poorly water-soluble APIs to replace the empirical approach often used today. The basic tyrosine-kinase inhibitor imatinib and six different acetylated amino acids were transferred into ILs. As compared to the free base and the mesylate salt, which is marketed by Novartis AG as Gleevec®, the dissolution rate as well as the supersaturation time was increased significantly. By changing the mesylate anion with its potential genotoxic risks, the total toxicity of the drug product could be decreased. The amorphous ILs proved adequate stability under forcing conditions and there was no recrystallization of the free base observed. The amorphous character of the ILs caused an increased amount of water vapour sorption which can be compensated by special packaging materials. Taken together, the presentation of imatinib as an IL is intended for oral administration as a tablet and can cause a reduction of dose because of the increased solubility. Therefore, the occurrence of side effects can be reduced as compared to Gleevec®. If there is actually an increased bioavailability to observe, has to be proved by the execution of animal trials. The novel NOX inhibitor VAS3947 is intended for the treatment of endothelial dysfunctions causing diseases like heart failure and stroke. The compounds poor aqueous solubility hindered further clinical development so far and make the drug candidate to remain in a very early stage of the drug development process. Therefore, different formulation concepts were evaluated in this study: An amorphous solid dispersion prepared from VAS3947 and Eudragit® L100 by means of spray drying was able to increase the dissolution rate and solubility of the compound significantly, but with the accomplished kinetic solubility being in the low µM range it is not possible to reach therapeutic plasma concentrations. In contrast, the incorporation into cyclodextrins resulted in an 760-fold increased solubility. Different cyclodextrins were evaluated. Especially the lipophilic derivatives of the β-cyclodextrin showed to be the most adequate excipients. The incorporation of the API into the cyclodextrin cavity was proved by means of NMR spectroscopy. Additionally, a formulation of VAS3947 and hydroxypropyl-β-cyclodextrin was prepared. This formulation is intended for the intravenous application during animal trials, which have to be conducted to get to know the pharmacokinetics of VAS3947. This formulation reached a concentration of 1 mg/mL spending striking protection of VAS3947 against degradation. Presentation of VAS3947 as a microemulsion system led also to increase the aqueous solubility of the compound, but not in the same extent as the cyclodextrin formulation. Beside the formulation development a physicochemical characterization was performed to get to know important parameters such as log P and pKa values of VAS3947. An HPLC method was developed and validated to analyse the extent of solubility improvement. A major issue of the compound VAS3947 and all related triazolopyrimidine derivatives, developed by Vasopharm GmbH, is the insufficient chemical stability because of presence of a hemiaminal moiety in the chemical structure. Stability investigations and an extensive biopharmaceutical characterization confirm the hindering of further clinical development by insufficient drug stability and high cytotoxicity. Poor aqueous solubility is an additional disadvantage which can be handled by a concerted formulation development.}, language = {en} } @article{Thalhammer2017, author = {Thalhammer, Johanna}, title = {L'art de bien chanter und Von der Kunst zierlich zu singen und zu spielen - Eine kontrastive Analyse von Texten der musikalischen Fachsprache im 18.

Both texts contain a chapter which gives explanations how to sing. The treatises include different types of technical words: specific terms easy identified as special language terms like names of ornaments in the music, special verbs standing for singing, and words and anaphors to describe tonality and dynamics. By having a look on the terms of music language, the influence of Italian and French words on German vocabulary of music becomes obvious.

We therefore aimed to investigate the adoption of adequate risk factor control and its determinants in the general population free of cardiovascular disease (CVD). Methods: Data from the Characteristics and Course of Heart Failure Stages A-B and Determinants of Progression (STAAB) Cohort Study, a population-based study of inhabitants aged 30 to 79 years from the general population of W{\"u}rzburg (Germany), were used. Proportions of participants without established CVD meeting targets for risk factor control recommended by 2016 ESC guideline were identified. Determinants of the accumulation of insufficiently controlled vascular risk factors (three or more) were assessed. Results: Between December 2013 and April 2015, 1379 participants without CVD were included; mean age was 53.1 ± 11.9 years and 52.9\% were female; 30.8\% were physically inactive, 55.2\% overweight, 19.3\% current smokers. Hypertension, dyslipidemia, and diabetes mellitus were prevalent in 31.8\%, 57.6\%, and 3.9\%, respectively. Treatment goals were not reached despite medication in 52.7\% of hypertensive, in 37.3\% of hyperlipidemic and in 44.0\% of diabetic subjects. Insufficiently controlled risk was associated with male sex (OR 1.94, 95\%CI 1.44-2.61), higher age (OR for 30-39 years vs. 70-79 years 4.01, 95\%CI 1.94-8.31) and lower level of education (OR for primary vs. tertiary 2.15, 95\%CI 1.48-3.11). Conclusions: In the general population, prevalence of vascular risk factors was high. We found insufficient identification and control of vascular risk factors and a considerable potential to improve adherence to cardiovascular guidelines for primary prevention. Further studies are needed to identify and overcome patient- and physician-related barriers impeding successful control of vascular risk factors in the general population.}, language = {en} } @misc{Tischer2017, author = {Tischer, Anuschka}, title = {Deutsche Reichstagsakten, Deutsche Reichstagsakten.
