Mecánica rotacional ventricular izquierda invertida en un paciente con lipedema (del estudio de MAGYAR-Path)
2019
Resumen: El lipedema es un trastorno crónico que se caracteriza por una hiperplasia del tejido adiposo subcutáneo simétrico, deformante, asociado a hematomas y dolor, que afecta fundamentalmente a mujeres tras la pubertad, que suele ser familiar y tiene influencia hormonal. Sin tratamiento, el lipedema puede progresar a linfedema, y se ha asociado al aumento en la rigidez de la aorta. La mecánica rotacional del ventrículo izquierdo (VI) tiene un papel significativo en la circulación normal. En circunstancias normales, la base del VI rota en el sentido de las agujas del reloj, mientras que el ápex del VI rota en sentido contrario, provocando un movimiento como de retorcer una toalla llamado …
Zur Bedeutsamkeit von Operationalisierungen medienpädagogischer Grundbegriffe: Kritisch-rationale Anmerkungen zur Medienbildung
2017
Der hier dargestellte Entwurf einer kritisch-rationalen Medienbildung basiert auf dem Entwurf einer kritisch-rationalen Medienpädagogik. Die Medienpädagogik im Allgemeinen und die Medienbildung im Speziellen müssen sich in der Bestimmung ihrer Grundbegriffe auf allgemeinpädagogische Arbeiten rückbeziehen und sollten nicht versuchen, ihre Grundbegriffe komplett neu zu definieren. Dies wird in diesem Beitrag exemplarisch für die Grundbegriffe Erziehung, Sozialisation und Bildung getan. Der Bildungsbegriff wird ausführlicher behandelt und es wird dafür plädiert, zwischen einer Medienausbildung und Medienselbstbildung zu unterscheiden. Beide Aspekte sind gleichermassen relevant für die Medienbi…
Soluble Platelet Release Factors as Biomarkers for Cardiovascular Disease
2021
Platelets are the main players in thrombotic diseases, where activated platelets not only mediate thrombus formation but also are involved in multiple interactions with vascular cells, inflammatory components, and the coagulation system. Although in vitro reactivity of platelets provides information on the function of circulating platelets, it is not a full reflection of the in vivo activation state, which may be relevant for thrombotic risk assessment in various disease conditions. Therefore, studying release markers of activated platelets in plasma is of interest. While this type of study has been done for decades, there are several new discoveries that highlight the need for a critical a…
Increased Body Weight and Fat Mass After Subchronic GIP Receptor Antagonist, but Not GLP-2 Receptor Antagonist, Administration in Rats
2019
Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-2 (GLP-2) are hormones secreted from the enteroendocrine cells after a meal. They exert their actions through activation of G protein-coupled receptors (R), the GIPR and GLP-2R, respectively. Both have been reported to influence metabolism. The purpose of the study was to investigate the role of the hormones in the regulation of lipid and bone homeostasis by subchronic treatment with novel GIPR and GLP-2R antagonists. Rats were injected once daily with vehicle, GIPR, or GLP-2R antagonists for 3 weeks. Body weight, food intake, body composition, plasma lipoprotein lipase (LPL), adipokines, triglycerides and the mark…
Platelet Pathogen Reduction Technologies Alter the MicroRNA Profile of Platelet-Derived Microparticles
2020
Despite improvements in donor screening and increasing efforts to avoid contamination and the spread of pathogens in clinical platelet concentrates (PCs), the risks of transfusion-transmitted infections remain important. Relying on an ultraviolet photo activation system, pathogen reduction technologies (PRTs), such as Intercept and Mirasol, utilize amotosalen, and riboflavin (vitamin B2), respectively, to mediate inactivation of pathogen nucleic acids. Although they are expected to increase the safety and prolong the shelf life of clinical PCs, these PRTs might affect the quality and function of platelets, as recently reported. Upon activation, platelets release microparticles (MPs), which …
The Bioactive Compounds and Antioxidant Activity of Food Products of Rhizophora stylosa Fruit (Coffee and Tea Mangrove)
2018
The objective of this study is to investigate the bioactive compounds and antioxidant activity of coffee and tea mangrove (locally known in Indonesia) produced from the fruit of Rhizophora stylosa. Furthermore, three raw materials of coffee mangrove were also investigated to clarify their potencies. The crude extracts of five samples were subjected to antioxidant assay using DPPH. The results show that the extract of tea mangrove has the strongest activity; then, it was successfully fractionated using different polarity of solvents and yielded acetone and methanol fractions that had high antioxidant activity. The acetone fraction was purified and gave fractions A1, A2, A3, A4, A5, and A6, b…
