    Description: Der Beitrag greift den aktuellen Diskussionsstand um die Transformation des bisherigen Systems der Sondersammelgebiete (SSG) zur Förderung von Fachinformationsdiensten (FID) auf und skizziert den Übergang am Beispiel des FID Medien- und Kommunikationswissenschaft an der UB Leipzig. Es werden die Vorteile der neuen Förderrichtlinie, die Ausgestaltung des FID und die noch zu bewältigenden Problemfelder dargestellt. The current state of discussion about transforming the former Special Subject Fields Programme into a funding of Specialized Information Services is presented. The transition is illustrated using the example of the Information Service for Media and Communication Studies of the Leipzig University Library. The paper explains the advantages of the new funding programme as well as the design of the information service and the problem areas which are yet to be mastered.

    Description: Im Zuge der Entwicklung des Fachinformationsdienstes für Medien- und Kommunikationswissenschaft an der Universitätsbibliothek Leipzig hat der Autor eine onlinegestützte Befragung in der Fachcommunity vorgenommen. Ziel der Befragung war es, Bedürfnisse und Gewohnheiten der Wissenschaftlerinnen und Wissenschaftler hinsichtlich der Versorgung mit Literatur zu erfahren. Die Befragung ergab, dass die Mehrheit der Befragten verschiedene Recherchequellen nutzen muss, um relevante Literatur aufzufinden. Obwohl E-Books parallel genutzt werden, betrachten die meisten Befragten gedruckte Literatur als einfacher in der Handhabung. Umgekehrt verhält es sich bei Zeitschriften. Hier wird die elektronische Variante der gedruckten vorgezogen. Leipzig University Library is currently developing an Information Service for Communication and Media Studies. In preparation, the author conducted an online survey amongst academics in the discipline of Communication and Media Studies in order to learn more about their needs and habits when researching literature. For the majority of the academics who were interviewed it is necessary to search different sources to find the literature they need. Although they also use e-books, most academics prefer print publications because the handling is seen as easier. With journals it is the other way round: Electronic journals are preferred over printed journals.

    Description: Zusammenfassung Der Beitrag erörtert die Entwicklung des Video-Streaming-Marktes und die Bedeutung für Öffentliche und wissenschaftliche Bibliotheken. Dabei geht er auch auf die Spezialisierung bestimmter Anbieter ein. Zusammenfassend ist festzuhalten, dass Streaming von AV-Medien vor allem für Öffentliche Bibliotheken ein wertvolles Zusatzangebot für Nutzende darstellt, für wissenschaftliche Bibliotheken hinsichtlich der Dauerhaftigkeit, Zitierfähigkeit und Nachnutzbarkeit von Ressourcen noch wesentliche Fragen ungelöst bleiben.

    Description: The trace element selenium is of high importance for many of the body's regulatory and metabolic functions. Balanced selenium levels are essential, whereas dysregulation can cause harm. A rapidly increasing number of studies characterizes the wide range of selenium dependent functions in the human body and elucidates the complex and multiple physiological and pathophysiological interactions of selenium and selenoproteins. For the majority of selenium dependent enzymes, several biological functions have already been identified, like regulation of the inflammatory response, antioxidant properties and the proliferation/differentiation of immune cells. Although the potential role of selenium in the development and progression of cardiovascular disease has been investigated for decades, both observational and interventional studies of selenium supplementation remain inconclusive and are considered in this review. This review covers current knowledge of the role of selenium and selenoproteins in the human body and its functional role in the cardiovascular system. The relationships between selenium intake/status and various health outcomes, in particular cardiomyopathy, myocardial ischemia/infarction and reperfusion injury are reviewed. We describe, in depth, selenium as a biomarker in coronary heart disease and highlight the significance of selenium supplementation for patients undergoing cardiac surgery.

    Description: Cardiovascular diseases are the main cause of death worldwide, demanding new treatments and interventions. Recently, extracellular vesicles (EVs) came in focus as important carriers of protective molecules such as miRNAs and proteins which might contribute to e.g. improved cardiac function after myocardial infarction. EVs can be secreted from almost every cell type in the human body and can be transferred via the bloodstream in almost every compartment. To provide an all-encompassing overview of studies investigating these beneficial properties of EVs we performed a systematic review/meta-analysis of studies investigating the cardioprotective characteristics of EVs. Forty-three studies were investigated and catalogued according to the EV source. We provide an in-depth analysis of the purification method, size of the EVs, the conducted experiments to investigate the beneficial properties of EVs as well as the major effector molecule encapsulated in EVs mediating protection. This study provides evidence that EVs from different cell types and body fluids provide cardioprotection in different in vivo and in vitro studies. A meta-analysis was performed to estimate the underlying effect size. In conclusion, we demonstrated that EVs from different sources might serve as a promising tool for treating cardiovascular diseases in the future.

    Description: Selenoprotein P (SELENOP) is an established biomarker of selenium (Se) status. Serum SELENOP becomes saturated with increasing Se intake, reaching maximal concentrations of 5-7 mg SELENOP/L at intakes of ca. 100-150 µg Se/d. A biomarker for higher Se intake is missing. We hypothesized that SELENOP may also reflect Se status in clinical applications of therapeutic dosages of selenite. To this end, blood samples from two supplementation studies employing intravenous application of selenite at dosages 〉1 mg/d were analyzed. Total Se was quantified by spectroscopy, and SELENOP by a validated ELISA. The high dosage selenite infusions increased SELENOP in parallel to elevated Se concentrations relatively fast to final values partly exceeding 10 mg SELENOP/L. Age or sex were not related to the SELENOP increase. Western blot analyses of SELENOP verified the results obtained by ELISA, and indicated an unchanged pattern of immunoreactive protein isoforms. We conclude that the saturation of SELENOP concentrations observed in prior studies with moderate Se dosages (〈400 µg/d) may reflect an intermediate plateau of expression, rather than an absolute upper limit. Circulating SELENOP seems to be a suitable biomarker for therapeutic applications of selenite exceeding the recommended upper intake levels. Whether SELENOP is also capable of reflecting other supplemental selenocompounds in high dosage therapeutic applications remains to be investigated.
