BACKGROUND Irisin is a new myokine secreted from the skeletal muscle and appears to affect the metabolism of adipose tissue. OBJECTIVES The mechanisms of cellular and molecular identification by which exercise training exerts its benefits remain unclear and are under investigation. METHODS We examined the effect of 8-week resistance exercise on plasma irisin levels and expression profiles o...

Purpose: To compare the efficiency of an aerobic physical training program prescribed according to either velocity associated with maximum oxygen uptake (vVO2max) or peak running speed obtained during an incremental treadmill test (Vpeak_K) in mice. Methods: Twenty male Swiss mice, 60 days old, were randomly divided into two groups with 10 animals each: 1. group trained by vVO2max (GVO2), 2. gr...

BACKGROUND It is widely acknowledged that there is need for redesign of internal medicine training. Duty hour restrictions, an increasing focus on patient safety, the possibility of inadequate training in ambulatory care, and a growing shortage of primary care physicians are some factors that fuel this redesign movement. INTERVENTION We implemented a 4∶1 scheduling template that alternates tr...
