From theCambridge English Corpus The effect of oxygen radicals duringreperfusionproducing peroxidation and cellular injury is well described for other tissue beds during normothermia. From theCambridge English Corpus And finally areperfusioninjury characterized by free radical formation and oxidative stress. From theCambridge English Corpus This difference was particularly marked at 30 minutes, 60 minutes, and 90 minutes ofreperfusion. From theCambridge English Corpus Other laboratory studies have supported our finding of differential regionalreperfusion. From theCambridge English Corpus There are no additional studies, either animal or clinical, which discuss the time ofreperfusionnecessary to replete cerebral stores of energy to normal. From theCambridge English Corpus The permeability of the blood-brain barrier was highly increased by ischemia/reperfusion. From theCambridge English Corpus With the resumption of blood flow, the subsequentreperfusionproduces large quantities of superoxide radical and hydrogen peroxide. From theCambridge English Corpus Alternatively, excess formation of oxygen radicals after arrest associated withreperfusionmay cause or exacerbate cerebral injury. From theCambridge English Corpus Our findings of differential regionalreperfusionfollowing hypothermic circulatory arrest also have important implications. From theCambridge English Corpus Addition of insulin to those solutions may be beneficial to protect immature myocardium from hypothermic, ischemic orreperfusioninjury. From theCambridge English Corpus Compared to sham controls, myelin processes began to degenerate at 12 hoursreperfusion, with a significant loss of intact processes by 48 hours. From theCambridge English Corpus Taken together, these findings illustrate that the brain has a heterogeneous response to ischemia andreperfusioninjury. From theCambridge English Corpus Following cerebral ischemia andreperfusionthere is a downregulation of the protein synthesis machinery and translation arrest. From theCambridge English Corpus Rewarming is commenced, and, duringreperfusion, pacemaker wires are placed on the atrium and ventricle, and a pulmonary venous catheter is inserted.
