DOI: 10.1016/j.freeradbiomed.2017.10.170
Abstract: A serious consequence of ischemia-reperfusion injury (I/R) is oxidative damage leading to mitochondrial dysfunction. Such I/R-induced mitochondrial dysfunction is observed as impaired state 3 respiration, decreased ATP generation, and overproduction of O2. The cascading ROS… read more here.
