Examplesofreperfusion
reperfusionAlthough myocardialreperfusioncan rescue the number of necrotic cardiac myocytes, it is critically dependent upon the time of intervention after ischaemic insult.From theCambridge English CorpusThe effect of oxygen radicals duringreperfusionproducing peroxidation and cellular injury is well described for other tissue beds during normothermia.From theCambridge English CorpusAnd finally areperfusioninjury characterized by free radical formation and oxidative stress.From theCambridge English CorpusThis difference was particularly marked at 30 minutes, 60 minutes, and 90 minutes ofreperfusion.From theCambridge English CorpusOther laboratory studies have supported our finding of differential regionalreperfusion.From theCambridge English CorpusThere are no additional studies, either animal or clinical, which discuss the time ofreperfusionnecessary to replete cerebral stores of energy to normal.From theCambridge English CorpusThe permeability of the blood-brain barrier was highly increased by ischemia/reperfusion.From theCambridge English CorpusWith the resumption of blood flow, the subsequentreperfusionproduces large quantities of superoxide radical and hydrogen peroxide.From theCambridge English CorpusAlternatively, excess formation of oxygen radicals after arrest associated withreperfusionmay cause or exacerbate cerebral injury.From theCambridge English CorpusOur findings of differential regionalreperfusionfollowing hypothermic circulatory arrest also have important implications.From theCambridge English CorpusAddition of insulin to those solutions may be beneficial to protect immature myocardium from hypothermic, ischemic orreperfusioninjury.From theCambridge English CorpusCompared to sham controls, myelin processes began to degenerate at 12 hoursreperfusion, with a significant loss of intact processes by 48 hours.From theCambridge English CorpusTaken together, these findings illustrate that the brain has a heterogeneous response to ischemia andreperfusioninjury.From theCambridge English CorpusFollowing cerebral ischemia andreperfusionthere is a downregulation of the protein synthesis machinery and translation arrest.From theCambridge English CorpusRewarming is commenced, and, duringreperfusion, pacemaker wires are placed on the atrium and ventricle, and a pulmonary venous catheter is inserted.From theCambridge English CorpusThese examples are from corpora and from sources on the web.
