Figure 1From: Mediation of exogenous hydrogen sulfide in recovery of ischemic post-conditioning-induced cardioprotection via down-regulating oxidative stress and up-regulating PI3K/Akt/GSK-3β pathway in isolated aging rat hearts Summary of experimental protocols. After instrumentation and 20 min stabilization, all hearts subjected to 40 min global ischemia and 60 min reperfusion. For details of ischemic postconditioning, NaHS, LY294002 and NAC treatments see text.Back to article page
