Reperfusion Protection in Obligate Hibernators
Obligatory hibernators such as the ground squirrels show resistance to ischemia/reperfusion (I/R) injury in liver, heart, and small intestine during the hibernation season when there is a switch from carbohydrate metabolism to lipid metabolism for cellular energy supply. This metabolic switch limits anaerobic metabolism and the formation of lactate, a herald of poor prognosis and multi-organ failure (MOF) after I/R injury. In addition, the increase in lipid metabolism generates ketone bodies and activates peroxisome proliferating-activated receptors (PPARs), both of which have been shown to be protective against I/R injury.

Famous quotes containing the word protection:
“Were for statehood. We want statehood because statehood means the protection of our farms and our fences; and it means schools for our children; and it means progress for the future.”
—Willis Goldbeck (19001979)
