The prevention of endothelial dysfunction through endothelial cell apoptosis inhibition in a hypercholesterolemic rabbit model: the effect of L-arginine supplementation.

Background: The impact of L-arginine on atherogenesis and its ability to prevent endothelial dysfunction have been studied extensively during the past years. L-arginine is a substance for nitric oxide synthesis which involves in apoptosis. Hypercholesterolemia promotes endothelial dysfunction, and it is hypothesized that L-arginine prevents endothelial dysfunction through endothelial cells apoptosis inhibition.

Integrating physical examination and trunk anatomy; a new course for second year medical students.

The aim of this study was to determine the effect of an integrated course of physical examination and trunk anatomy on second year medical students' attitude and knowledge of anatomy. Thirty nine second year medical students attended a physical examination course (5 small group sessions) related to topics in trunk anatomy (2004/05). Students in control group attended routine anatomy lectures and problem based learning discussions relevant to their physiology course.
