...Brynne M. Duffy; Catherine M. Ivy; James F. Staples ABSTRACT Hibernating Ictidomys tridecemlineatus , 13-lined ground squirrels, are considered models of ischaemia–reperfusion tolerance, as both tissues and isolated mitochondria withstand anoxia followed by rapid re-oxygenation in vitro...

...Brittney G. Borowiec; Graham R. Scott ABSTRACT Hypoxia is common in aquatic environments, and exposure to hypoxia followed by re-oxygenation is often believed to induce oxidative stress. However, there have been relatively few studies of reactive oxygen species (ROS) homeostasis and oxidative...

... variations. In this study, we investigated the responses of oyster gill mitochondria to short-term hypoxia (3 and 12 h, at 1.7 mg O 2 l −1) and subsequent re-oxygenation. Mitochondrial respiratory rates (states 3 and 4 stimulated by glutamate) and phosphorylation efficiency [respiratory control ratio (RCR...
