BACKGROUND Reactive oxygen species- (ROS-) mediated ischemia-reperfusion injury (IRI) detrimentally impacts liver transplantation and resection. 12/15-Lipoxygenase (12/15-LOX), an antagonistic protein of the glutathione peroxidase 4 (GPX4) signaling cascade, was proven to mediate cell death in postischemic cerebral and myocardial tissue. The aim of this study was to investigate the impact of 12...
The restriction of proteins has recently emerged as the most important factor for the beneficial effects of calorie restriction. Hine et al. now provide strong evidence for the role of the hydrogen sulfide (H2S) gas in the protective effects of calorie and protein restriction against ischemia/reperfusion injury (IRI) but also implicate H2S in longevity extension in model organisms.
In this study, we evaluated the effect of astragaloside IV (Ast IV) post-ischemia treatment on myocardial ischemia-reperfusion (IR) injury (IRI). We also examined whether hypoxia inducible factor-1α (HIF-1α) and its downstream gene-inducible nitric oxide (NO) synthase (iNOS) play roles in the cardioprotective effect of Ast IV. Cultured cardiomyocytes and perfused isolated rat hearts were expose...
Objective-Ovarian torsion must be diagnosed and treated as much early as possible. The aim of the present study was to investigate effects of interaperitoneal administration of curcumin on ischemia-reperfusion injury in ovaries. Design- Experimental Study Animals- Twent-four healthy female Wistar rats Procedures- Twent-four healthy female Wistar rats weighing approximately 260...
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...
Renal ischemia-reperfusion injury (IRI) is a major cause of acute kidney injury (AKI). Our previous studies have shown that the total flavonoids (TFs) from Rosa laevigata Michx fruit has various activities, however, there were no papers reporting the role of the TFs against renal IRI. In the present work, a hypoxia/reoxygenation (H/R) model in NRK-52E cells and ischemia-reperfusion model in rat...
Abstract INTRODUCTION Lower limb ischemia-reperfusion injury (IRI-LL) is a common major complication in orthopaedic surgery, especially elderly patients. We previously demonstrated that folic acid reduced IRI-LL damage 3–4-month-old rats. Current work analyses the effect of prevention animals. MATERIAL AND METHODS Thirty-six 12-month-old male WAG/RijHsd rats were subjected to 3 hours ischaemia....
Edaravone, an effective free radical scavenger, can alleviate myocardial ischemia-reperfusion injury (IRI) by decreasing reactive oxygen species (ROS) accumulation. The speckle tracking imaging (STI) could precisely and objectively evaluate the global and regional myocardial deformation. The aim of our study was to assess the protective effect of edaravone postconditioning on IRI in rabbits by ...
abstract introduction: resent studies have been shown beneficial effects of hyperoxia pretreatment against ischemia-reperfusion injury in different organs. the aim of the present study was to investigate early and late effects of normobaric hyperoxia (≥95% o2) pretreatment on ischemia-reperfusion injuries in isolated rat hearts. methods: following 60 and 180 minutes of hyperoxia, rat hearts wer...
background: ischemia reperfusion (ir) is the main pathology of torsion of testis and it is a common urologic emergency. there is some evidence that shows oxytocin (ot) plays role in ischemia reperfusion. objective: to evaluate this hypothesis that ot can decrease germ cell apoptotic index in testis under acute ischemia reperfusion in a rat model. materials and methods: 20 adult rats were random...
