New physiology study findings have been published by scientists at Hebrew University, Faculty of Dental Medicine
Published in Cardiovascular Device Liability Week, September 9th, 2007
Scientists discuss in "Altered Ca2+ handling and myofilament desensitization underlie cardiomyocyte performance in normothermic and hyperthermic heat-acclimated rat hearts" new findings in physiology. According to a study from Jerusalem, Israel, "Heat acclimation (AC) improves cardiac mechanical and metabolic performance. Using cardiomyocytes and isolated hearts from 30-day and 2-day acclimated rats (AC and AC-2d, 34 degrees C), we characterized cellular contractile mechanisms under normothermic (37 degrees C) and hyperthermic (39-42 degrees C) conditions."
"To determine contractile responses, Ca2+ transients (Ca2+ T), sarcoplasmic reticulum (SR) Ca2+ pool size...
