Effects of Postconditioning, Preconditioning and Perfusion of L-carnitine During Whole Period of Ischemia/ Reperfusion on Cardiac Hemodynamic Functions and Myocardial Infarction Size in Isolated Rat Heart

Pathophysiology of Ischemia/Reperfusion-induced Myocardial Injury: What We Have Learned From Preconditioning and Postconditioning?

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 mechan...

Neuroprotective Effects of Ischemic Preconditioning and Postconditioning on Global Brain Ischemia in Rats through the Same Effect on Inhibition of Apoptosis

Transient forebrain or global ischemia induces neuronal death in vulnerable CA1 pyramidal cells with many features. A brief period of ischemia, i.e., ischemic preconditioning, or a modified reperfusion such as ischemic postconditioning, can afford robust protection of CA1 neurons against ischemic challenge. Therefore, we investigated the effect of ischemic preconditioning and postconditioning o...

Combined Preconditioning and Postconditioning Provides Synergistic Protection against Liver Ischemic Reperfusion Injury

Hepatic Ischemia and Reperfusion Injury (IRI) is a major cause of liver damage during liver surgery and transplantation. Ischemic preconditioning and postconditioning are strategies that can reduce IRI. In this study, different combined types of pre- and postconditioning procedures were tested in a murine warm hepatic IRI model to evaluate their protective effects. Proanthocyanidins derived fro...

Characterization of the postconditioning effect of dexmedetomidine in mouse organotypic hippocampal slice cultures exposed to oxygen and glucose deprivation.

BACKGROUND There is an increasing interest in the use of dexmedetomidine for anesthesia and sedation. Here, we used the mouse organotypic hippocampal slice culture to investigate whether dexmedetomidine exhibits postconditioning properties against oxygen and glucose deprivation (OGD). The role of the focal adhesion and extracellular-regulated kinases pathways in these effects were examined in b...

ASIC1a contributes to neuroprotection elicited by ischemic preconditioning and postconditioning.

Acid-sensing ion channels, ASICs, are proton-gated cation channels widely expressed in peripheral sensory neurons and in neurons of the central nervous system that play an important role in a variety of physiological and pathological processes. To further confirm the role played by ASIC1a in cerebral ischemia, here we examined the involvement of this channel in two endogenous recently character...
