Introduction Ischemic postconditioning is a method that shows evidence of efficacy in minimizing reperfusion injury; however, its effectiveness in preventing injuries in distant organs is still unknown, especially in those who have undergone mesenteric ischemia and reperfusion. Objective To evaluate the effect of ischemic postconditioning in preventing reperfusion injury in the liver of rats ...

This review analyzes recent data on mechanisms of cerebral hypoxia and the protective methods of hypoxic and ischemic postconditioning, as well as their interrelationship with the key mechanisms responsible for neuroprotection and neuroplasticity. Upregulation of expression of antiapoptotic factors and neurotrophins and modulation of activity of several protein kinases and transcription factors...

BACKGROUND Outcomes after acute myocardial infarction in patients with chronic kidney disease are extremely poor. Ischemic conditioning techniques are among the most powerful cytoprotective strategies discovered to date. However, experimental data suggest that comorbidity may attenuate the protective effects of ischemic conditioning. METHODS AND RESULTS We conducted investigations into the ef...

Reperfusion is mandatory to salvage ischemic myocardium from infarction, but reperfusion per se contributes to injury and ultimate infarct size. Therefore, cardioprotection beyond that by timely reperfusion is needed to reduce infarct size and improve the prognosis of patients with acute myocardial infarction. The conditioning phenomena provide such cardioprotection, insofar as brief episodes o...

BACKGROUND AND PURPOSE Postconditioning may be a clinically feasible way to protect the brain after a stroke. However, its effects during the recovery phase post stroke remain to be fully elucidated. Here, we examine the hypothesis that ischemic postconditioning amplifies neurogenesis and angiogenesis during stroke recovery. METHODS Male Sprague-Dawley rats were subjected to 100-minute transi...

Protection of the heart from ischemia-reperfusion injury can be achieved by ischemic preconditioning and ischemic postconditioning. Previous studies revealed that a complex of pannexin-1 with the P2X(7) receptor forms a channel during ischemic preconditioning and ischemic postconditioning that results in the release of endogenous cardioprotectants. ATP binds to P2X(7) receptors, inducing the fo...

Ischemic heart disease, also known as coronary heart disease or coronary artery disease, accounts for >50% of cardiovascular events and is a leading cause worldwide of morbidity and mortality. Hypoperfusion of the heart is the major cause of injury in ischemic heart disease, as it results in the death of cardiomyoctes due to a lack of oxygen and energy. This injury ultimately leads to a dead ar...

Objective(s): Chronic diabetes impedes cardioprotection in reperfusion injury and hence protecting the diabetic heart would have important outcomes. In this study, we evaluated whether combined postconditioning with ischemia and cyclosporine-A can restore oxidative stress and histopathological changes in reperfusion injury of the diabetic myocardium. Materials and Methods: Streptozocin-induced ...
