"Die Goethe-Universität ist eine weltoffene Werkstatt der Zukunft mitten in Europa. 1914 von BürgerInnen für BürgerInnen gegründet, hat sie seit 2008 als autonome Stiftungsuniversität an diese Tradition wieder angeknüpft. Ihrer wechselvollen Geschichte kritisch verpflichtet, ist sie geleitet von den Ideen der Europäischen Aufklärung, der Demokratie und der Rechtsstaatlichkeit und wendet sich gegen Rassismus, Nationalismus und Antisemitismus. Die Goethe-Universität ist ein Ort argumentativer Auseinandersetzung; Forschung und Lehre stehen in gesellschaftlicher Verantwortung."
Dieses Leitbild strahlt an einem Freitagabend im Januar 2018 zwei Stunden lang über einem voll besetzten, unruhigen Hörsaal. Der groß an die Wand projizierte Text richtet sich an das Publikum einer Veranstaltung der "Frankfurter Bürgeruniversität" mit dem Titel "Diskurskultur im Zwielicht – Wie viel Meinungsfreiheit verträgt die Uni?" Die Atmosphäre ist für eine öffentliche Abendveranstaltung ungewöhnlich angespannt: Menschen mit unterschiedlichen politischen Einstellungen sitzen dicht beieinander, ein paar Burschenschaftler mit Schärpe nehmen die Mitte des Saales ein, es gibt Gerüchte, die AfD habe zu der Veranstaltung mobilisiert. ...
Bislang existieren kaum (musik-)psychologische Studien, welche die gesundheitliche Situation von Berufssänger/innen adressieren. Mit N = 313 Teilnehmenden handelt es sich bei der hier vorgestellten Forschungsarbeit um eine der bislang größten Studien, in welcher gesundheitspsychologische Aspekte bei Profisänger/innen untersucht wurden. Es konnte gezeigt werden, dass die Sänger/innen trotz hoher beruflicher Belastungen in 16 von 27 Burnout-Kennwerten niedrigere Werte aufweisen als die Personen der repräsentativen Vergleichsstichprobe. Bei den elf anderen Burnout-Kennwerten zeigte sich kein statistisch signifikanter Unterschied zwischen den beiden Gruppen. Mit den in den Regressionsanalysen berücksichtigten Prädiktoren lassen sich bis zu 40 Prozent des Kriteriums Burnout erklären. Als aussagekräftigste Prädiktoren konnten die Variablen Erholungskompetenz, Optimismus und Pessimismus identifiziert werden. Perfektionismus als unter Musiker/innen häufig stark ausgeprägte Persönlichkeitseigenschaft trug wider Erwarten kaum zur Vorhersage der Burnout-Ausprägungen der Berufssänger/innen bei. Für präventive und rehabilitative Maßnahmen mit Profisänger/innen lässt sich aus den Befunden mit Blick auf eine (potenzielle) Burnout-Erkrankung die Empfehlung ableiten, sich eher auf die Ressourcen der Musiker/innen (Erholungskompetenz, Optimismus) zu konzentrieren und weniger auf deren scheinbare Defizite (Perfektionismus).
Lehre im Bewegungsfeld Kämpfen an den sportwissenschaftlichen Hochschuleinrichtungen in Deutschland
(2018)
Obwohl sich verschiedene Formen des Kämpfens in zahlreichen Lehrplänen der Bundesländer wiederfinden und ein entsprechender Qualifizierungsbedarf angehender Lehrkräfte gefordert wird, liegen bislang kaum Daten zur Lehre im Bewegungsfeld Kämpfen an sportwissenschaftlichen Hochschuleinrichtungen vor. Im Frühjahr 2017 wurden deutschlandweit Personen mit lehrender oder koordinierender Tätigkeit im Bewegungsfeld Kämpfen zu grundlegenden Daten ihrer Lehrveranstaltung (u. a. Zielgruppe, Umfang, Verbindlichkeit), zur didaktisch-methodischen Gestaltung (u. a. Ziele, Inhalte, Methoden, Prüfungen) sowie zu ihrem Beschäftigungsverhältnis befragt. An 14 von 60 Standorten konnte kein entsprechendes Lehrangebot identifiziert werden. Die erfassten 54 Lehrangebote (beschrieben von 48 Personen aus 31 Einrichtungen) sind bezüglich der organisatorischen Rahmenbedingungen relativ gut vergleichbar: Etwa 83 % umfassen zwei SWS und ca. 74 % sind Wahlpflichtveranstaltungen. Heterogenität herrscht u. a. hinsichtlich der Lernziele sowie der eingesetzten Lehr-Lernformen. Die Bestandserhebung bietet eine fachbezogene Diskussionsgrundlage für die Ausgestaltung von Theorie und Praxis des Bewegungsfelds Kämpfen.
NMR and chromatography methods combined with mass spectrometry are the most important analytical techniques employed for plant metabolomics screening. Metabolomic analysis integrated to transcriptome screening add an important extra dimension to the information flow from DNA to RNA to protein. The most useful NMR experiment in metabolomics analysis is the proton spectra due the high receptivity of 1H and important structural information, through proton–proton scalar coupling. Routinely, databases have been used in identification of primary metabolites, however, there is currently no comparable data for identification of secondary metabolites, mainly, due to signal overlap in normal 1H NMR spectra and natural variation of plant. Related to spectra overlap, alternatively, better resolution can be find using 1H pure shift and 2D NMR pulse sequence in complex samples due to spreading the resonances in a second dimension. Thus, in data brief we provide a catalogue of metabolites and expression levels of genes identified in soy leaves and roots under flooding stress.
The present study aims at analyzing the role of nativeness, the amount of input in L1 acquisition and the multilingual competence in the performance of Italian–German bilingual speakers. We compare novel data from the performance of adult L2 learners (L1: Italian; late L2: German) and that of heritage speakers (heritage language: Italian; majority language: German) to previous data from monolingual speakers of Italian. The comparison deals with the produced word order at the syntax-discourse interface in sentences containing New Information Subjects in answers to questions that prompt the identification of the clausal subject. Overall, adult L2 speakers and heritage speakers perform alike but crucially differently from Italian monolinguals. These data reveal that multilingual proficiency determines an increased variety in the adopted answering strategies; in particular, the German-like strategy is active in Italian. Nativeness alone is thus no guarantee for a homogeneous performance across groups, nor do we find similar patterns of performance in speakers who grew up as monolinguals. Data also show heritage speakers’ sensitivity to verb classes, with answering strategies varying in accordance with the verb argument structure. Participants’ productions reveal an interesting relation in sentences with transitive verbs between subject position (pre-/postverbal) and object form (lexical DP/clitic pronoun).
Formation and segregation of cell lineages forming the heart have been studied extensively but the underlying gene regulatory networks and epigenetic changes driving cell fate transitions during early cardiogenesis are still only partially understood. Here, we comprehensively characterize mouse cardiac progenitor cells (CPCs) marked by Nkx2-5 and Isl1 expression from E7.5 to E9.5 using single-cell RNA sequencing and transposase-accessible chromatin profiling (ATAC-seq). By leveraging on cell-to-cell transcriptome and chromatin accessibility heterogeneity, we identify different previously unknown cardiac subpopulations. Reconstruction of developmental trajectories reveal that multipotent Isl1+ CPC pass through an attractor state before separating into different developmental branches, whereas extended expression of Nkx2-5 commits CPC to an unidirectional cardiomyocyte fate. Furthermore, we show that CPC fate transitions are associated with distinct open chromatin states critically depending on Isl1 and Nkx2-5. Our data provide a model of transcriptional and epigenetic regulations during cardiac progenitor cell fate decisions at single-cell resolution.
GTP cyclohydrolase (GCH1) governs de novo synthesis of the enzyme cofactor, tetrahydrobiopterin (BH4), which is essential for biogenic amine production, bioactive lipid metabolism and redox coupling of nitric oxide synthases. Overproduction of BH4 via upregulation of GCH1 in sensory neurons is associated with nociceptive hypersensitivity in rodents, and neuron‐specific GCH1 deletion normalizes nociception. The translational relevance is revealed by protective polymorphisms of GCH1 in humans, which are associated with a reduced chronic pain. Because myeloid cells constitute a major non‐neuronal source of BH4 that may contribute to BH4‐dependent phenotypes, we studied here the contribution of myeloid‐derived BH4 to pain and itch in lysozyme M Cre‐mediated GCH1 knockout (LysM‐GCH1−/−) and overexpressing mice (LysM‐GCH1‐HA). Unexpectedly, knockout or overexpression in myeloid cells had no effect on nociceptive behaviour, but LysM‐driven GCH1 knockout reduced, and its overexpression increased the scratching response in Compound 48/80 and hydroxychloroquine‐evoked itch models, which involve histamine and non‐histamine dependent signalling pathways. Mechanistically, GCH1 overexpression increased BH4, nitric oxide and hydrogen peroxide, and these changes were associated with increased release of histamine and serotonin and degranulation of mast cells. LysM‐driven GCH1 knockout had opposite effects, and pharmacologic inhibition of GCH1 provided even stronger itch suppression. Inversely, intradermal BH4 provoked scratching behaviour in vivo and BH4 evoked an influx of calcium in sensory neurons. Together, these loss‐ and gain‐of‐function experiments suggest that itch in mice is contributed by BH4 release plus BH4‐driven mediator release from myeloid immune cells, which leads to activation of itch‐responsive sensory neurons.
Background: Effects of playing high stringed bow instruments on the upper body posture have not been analysed so far. The instrument-specific seating position when playing in an orchestra is compared to the habitual seating position.
Methods: Three dimensional back scans were performed in 13 professional violinists and viola players of a radio orchestra (8 f / 5 m). Trunk position in their habitual seating position and in the instrument- specific seating position imitating playing was compared. Statistical differences were calculated using Wilcoxon Matched Pairs Test with Bonferroni Holm correction.
Results: Significant differences were found between the seated position with instrument and without (p < 0.001, 0.03, 0.02 or 0.01) in the spine (trunk length, sagittal trunk decline, lumbar bending angle, maximal rotation, standard deviation rotation, lumbar lordosis), the shoulder (scapula distance, scapula rotation, scapula angle right) and pelvis distance.
Conclusions: Playing an instrument changes the static seating position by increased rotation of the spine and specific shoulder adaptations holding the instrument (left arm) and the bow (right arm), with minor effects on the pelvis. This forced position may result in chronic health effects. The method used in this study is an approach to better understand the involved muscular structures and possible resulting health damages.
Background/Aims: An estimated 80 million people worldwide are infected with viremic hepatitis C virus (HCV). Even after eradication of HCV with direct acting antivirals (DAAs), hepatic fibrosis remains a risk factor for hepatocarcinogenesis. Recently, we confirmed the applicability of microfibrillar-associated protein 4 (MFAP4) as a serum biomarker for the assessment of hepatic fibrosis. The aim of the present study was to assess the usefulness of MFAP4 as a biomarker of liver fibrosis after HCV eliminating therapy with DAAs.
Methods: MFAP4 was measured using an immunoassay in 50 hepatitis C patients at baseline (BL), the end-of-therapy (EoT), and the 12-week follow-up visit (FU). Changes in MFAP4 from BL to FU and their association with laboratory parameters including alanine aminotransferase (ALT), aspartate aminotransferase (AST), platelets, the AST to platelet ratio index (APRI), fibrosis-4 score (FIB-4), and albumin were analyzed.
Results: MFAP4 serum levels were representative of the severity of hepatic fibrosis at BL and correlated well with laboratory parameters, especially APRI (Spearman correlation, R²=0.80). Laboratory parameters decreased significantly from BL to EoT. MFAP4 serum levels were found to decrease from BL and EoT to FU with high statistical significance (Wilcoxon p<0.001 for both).
Conclusions: Our findings indicate that viral eradication resulted in reduced MFAP4 serum levels, presumably representing a decrease in hepatic fibrogenesis or fibrosis. Hence, MFAP4 may be a useful tool for risk assessment in hepatitis C patients with advanced fibrosis after eradication of the virus.
G-protein-coupled receptor (GPCR) expression is extensively studied in bulk cDNA, but heterogeneity and functional patterning of GPCR expression in individual vascular cells is poorly understood. Here, we perform a microfluidic-based single-cell GPCR expression analysis in primary smooth muscle cells (SMC) and endothelial cells (EC). GPCR expression is highly heterogeneous in all cell types, which is confirmed in reporter mice, on the protein level and in human cells. Inflammatory activation in murine models of sepsis or atherosclerosis results in characteristic changes in the GPCR repertoire, and we identify functionally relevant subgroups of cells that are characterized by specific GPCR patterns. We further show that dedifferentiating SMC upregulate GPCRs such as Gpr39, Gprc5b, Gprc5c or Gpr124, and that selective targeting of Gprc5b modulates their differentiation state. Taken together, single-cell profiling identifies receptors expressed on pathologically relevant subpopulations and provides a basis for the development of new therapeutic strategies in vascular diseases.
