Harman was the first to propose that the damaging effects of ROS may play a key role in the mechanism of aging. Genetic studies of such distantly related species as C. elegans, Drosophila melanogaster, and mice support this hypo

However, the fact that molecular O. exists in air as a free radical renders it a double-edged sword, capable of sustaining life in physiologically controlled amounts, yet fatal when in excess. The controlled delivery and stepwise reduction in PO. from

Why Paramilitary Operations Fail, the net effect of acute systemic hypoxia is limb vasodilation despite significant reflex increases in muscle sympathetic vasoconstrictor nerve activity and norepinephrine spillover. In this context, some studies in experimental animals and humans have documented that hypoxia can reduce the vasocon

Heat shock proteins are a group of highly preserved molecular chaperones, playing a crucial role in maintaining proper protein assembly, transport and function. Stress-induced upregulation
