Response of skeletal muscle mitochondria to hypoxia.

abstract：:Mammalian cardiomyocytes have limited regenerative capacity, such that cell death can result in a net loss of viable contractile elements and a decrease in cardiac functional reserve, both during normal ageing and after insults to the myocardium leading to heart failure. At least four types of cell death have been des...
