Ischemia-reperfusion injury is a composite of damage accumulated during reduced perfusion of an organ or tissue and the additional insult sustained during reperfusion. Such injury occurs in a wide variety of clinically important syndromes, such as ischemic heart disease and stroke, which are responsible for a high degree of morbidity and mortality worldwide. Basic research has identified a numb...

introduction: during hemorrhagic shock (hs), the kidneys are one of the primary target organs involved. oxidative stress is shown to be enhanced in different models of acute kidney injury (aki). remote ischemic preconditioning (rpc) by brief limb ischemia is considered to be a safe method to protect different organs from further damage. in this study, we investigated the effects of brief hind l...

Background CMR is the imaging modality of choice to quantify myocardial injury in studies of cardioprotection. Remote ischemic conditioning (RIC), using transient limb ischemia and reperfusion, is a novel therapeutic intervention, which can protect the heart against acute ischemiareperfusion injury (IRI). Whether RIC can reduce myocardial infarct (MI) size, and improve myocardial salvage in ST-...

BACKGROUND Ischemic insults during operation can cause ischemic-reperfusion injuries in brain as well as memory impairments. Total intravenous anesthesia (TIVA) is the preferred anesthetic method in brain surgery, as it utilizes motor evoked potential monitoring. And the use of opioids is common in TIVA. However there are few studies about ischemic protective effect of opioids to glial cells. ...
