background: the cardioprotective effect of ischemic preconditioning has been known for many years. since the temporary ischemia in the heart may cause lethal cardiac effects, the idea of creating ischemia in organs far from the heart such as limbs was raised as remote ischemic preconditioning (ripc). we hypothesized that the extension of ripc has more cardioprotective effect in patients undergo...

objective(s)ischemia-reperfusion injury (iri) is a leading cause of kidney transplantation failure, and ischemic-preconditioning (ipc) is a protective method against the iri. in the present study, the defensive effect of ipc on rats’ kidney was investigated and more importantly the differences between two genders were appraised.materials and methodsthirty two wistar rats were randomly allocated...

aim and background: remote ischemic preconditioning introduces brief episodes of ischemia and reperfusion which reduces long term ischemia in orthopaedic surgery. the aim of this study was to evaluate hemodynamic and respiratory effects of remote ischemic preconditioning in lower extremity orthopaedic surgeries. methods: in this clinical trial 40 patients scheduled for lower extremity surgery w...

objective: ischemic preconditioning (ipc) is an endogenous phenomenon that can induce ischemic tolerance (it) in variety of organs such as brain. in this study, we examined the intermittent and prolonged normobaric hyperoxia (ho) on neurologic deficit scores, infarct volume, and superoxide dismutase activity. materials and methods: the rats were divided to four main groups. first two main grou...

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: Calcium overload and free radical mediated damage in the mitochondria is the most important pathological changes associated with myocardial ischemic-reperfusion injury. The verapamil post-treatment has been previously reported to prevent reperfusion-induced myocardial injury but functional recovery may be delayed due to the drug's inherent direct myocardial depression effect. In the...

organ damage after reperfusion of previously viable ischemic tissues is defined as ischemia/reperfusion injury. the pathophysiology of ischemia/reperfusion injury involves cellular effect of ischemia, reactive oxygen species and inflammatory cascade. protection against ischemia/reperfusion injury may be achieved by preconditioning or postconditioning. in this review, we discuss basic mechanisms...
