Does the tutors' academic background influence the learning objectives in problem-based learning?

Problem-based learning (PBL) is an essential element of the curriculum of the Medical University of Vienna (MUV) and is performed in an eight steps model with: clarifying, defining, analysing, shifting & sorting, identifying learning objectives, going to learn and coming back to talk and feedback. With an annual intake of up to 740 students the MUV has to recruit PBL tutors from various academic backgrounds including undergraduate near-peer students. Therefore, we were interested to see whether a tutor's academic background had an influence on the resulting PBL sessions as reflected by the percentage of learning objectives (LOs) which were actually achieved in relation to the intended LOs.

Influence of a revision course and the gender of examiners on the grades of the final ENT exam--a retrospective review of 3961 exams.

Unlabelled: Revision courses should repeat already acquired knowledge and skills and mostly provide a basis for passing the following exam.

Aim: The aim of the study is to investigate the influence of a previously attended revision course on the grades achieved in a final exam (Ear, Nose and Throat Diseases). Additionally we ask the question whether the gender of the examiners plays a role concerning the marks or not.

L-Carnitine alters nitric oxide synthase activity in fibroblasts depending on the peroxisomal status.

Fibroblast cellular models are widely used for research on fatty acid metabolism. Due to the importance of L-carnitine in intermediary metabolism we studied the effects of L-carnitine on healthy human skin fibroblasts and fibroblasts without functional peroxisomes (Zellweger Syndrome) cultivated under carnitine deficiency, which is caused by standard media compositions. The application of physiological (0.
