On and off-pump coronary artery bypass surgery equally safe, effective for older patients

Older patients did as well after undergoing coronary bypass surgery off-pump as they did with the more costly "on-pump" procedure using a heart-lung machine to circulate blood and oxygen through the body during surgery, according to research presented today at the American College of Cardiology's 62nd Annual Scientific Session.

RBCs stored longer than 3 weeks begin to lose the capacity to deliver oxygen-rich cells to tissue

A small study from Johns Hopkins adds to the growing body of evidence that red blood cells stored longer than three weeks begin to lose the capacity to deliver oxygen-rich cells where they may be most needed.

Clothing closely linked to peak performance for skiers

The sport of cross-country skiing has always been preoccupied with its skis and waxing. Research now demonstrates that to shave off those extra hundredths of a second, competitive skiers should pay more attention to their clothing.

NO triggers RGS4 degradation to coordinate angiogenesis and cardiomyocyte growth

Myocardial hypertrophy, a thickening of the heart muscle, is an adaptation that occurs with increased stress on the heart, such as high blood pressure. As the heart muscle expands, it also requires greater blood flow to maintain access to oxygen and nutrients, necessitating an expansion of the cardiac vasculature.
