Szeto HH, Liu S, Soong Y, Birk AV. Improving mitochondrial bioenergetics under ischemic conditions increases warm ischemia tolerance in the kidney. Am J Physiol Renal Physiol 308: F11–F21, 2015. First published October 22, 2014; doi:10.1152/ajprenal.00366.2014.—Ischemia time during partial nephrectomy is strongly associated with acute and chronic renal injury. ATP depletion during warm ischemia...

conclusions treatment with epo and mel had a beneficial effect on renal ir injury. the results may also indicate that mel protects against morphological damage better than epo in renal ir injury. results ischemia-reperfusion significantly decreased the observed hb and hct values. the histopathological findings in the ir group confirmed that there was an increase in the hyaline cast and thickeni...

background renal ischemia reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered principal components involved in the pathophysiological tissue alterations observed during renal ir. objective in this study, we compared the effects of melatonin (mel) and erythropoietin (epo), which are known antioxidant and anti-inflammatory agents, in i...

Acute renal failure resulting from hypoperfusion and hypoxia is a significant clinical problem. Hypoxia activates the heterodimeric transcription factor hypoxia inducible factor (HIF), leading to changes in gene expression that promote tissue adaptation and survival. To determine whether HIF may protect the kidney from ischemia-reperfusion injury, we subjected hif1a(+/-) and hif2a(+/-) mice to ...

objective(s):acute kidney injury (aki), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  renal ischemia-reperfusion, one of the main causes of aki, is of particular importance in the setting of kidney transplantation. materials and methods: sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

HIGHLIGHTS Ischemia-reperfusion triggers acute kidney injury due to reactive oxygen species. Quercetin is an antioxidant flavonoid that modulate the Rennin-Angiotensin System. prevents tubular cell death, oxidation, and mitochondrial depolarization. interacts with angiotensin AT1 receptor.

Renal ischemia–reperfusion (IR) is inevitable in partial nephrectomy and kidney transplantation. Acute tubular necrosis (ATN) induced by renal IR causes the loss of functional units kidney, pathologically presenting as nonhomogeneous distribution normal uriniferous tubules usually used to characterize activity. Optical coherence tomography (OCT) has been proven have ability image microstructure...

global cerebral ischemia (gci) and reperfusion induced apoptosis that lead to cell injury and death. the bax and bcl-2 are pro-apoptotic and anti-apoptotic genes, respectively. these genes belong to the b-cell lymphoma-2 (bcl-2) family.in this study; we assessed the effect of pentoxifylline drug on bax/bcl2 gene dosage expression changes following   ischemic reperfusion injury in kidney. in thi...

Stem cells therapy has been suggested as a promising option for the treatment of acute kidney injury (AKI). This study was performed to compare the abilities of xenogenic transplantation of human adipose stromal vascular fraction (SVF) and adipose-derived mesenchymal stem cells (AdMSCs) to facilitate the recovery of renal function and structure in a rat model of ischemia/reperfusion (IR) induce...
