Does exercise promote collateral artery growth mediated by monocytic nitric oxide?
Circulating mononuclear cell-derived inducible nitric oxide is an important mediator of exercise-induced collateral artery growth.
These data indicate that thermoregulatory responses in the elderly are initiated at temperatures approximately 1.2 degrees C less than that in younger patients. Thus, it is likely that elderly surgical patients become more hypothermic than do younger patients, at least in part, because they fail to trigger protective thermoregulatory responses.
