We tested the hypothesis that an upregulation of antioxidant proteins [Cu-Zn superoxide dismutase (SOD), Mn SOD, catalase, glutathione peroxidase, and glutathione peroxidase] plays a role in the delayed protection against myocardial stunning produced

We have described whole body oxygen (O2) extraction ratio (ER) as a reliable indicator of transfusion need in acute normovolemic anemia. In normal hearts, myocardial lactate production (-LACT), indicating anaerobic metabolism, does not occur until th
