Introduction: Reactive oxygen species (ROS) have been suggested to play an important role in the myocardial damage induced by ischemia – reperfusion. One element believed to be activated by ROS and to contribute to the reduction of ROS production, is the uncoupling protein-2 (UCP2). The objective of this investigation was to explore the effect of myocardial ischemia reperfusion on cardiac UC...

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...

Introduction: Nucleobinding-2 (NUCB2) or nesfatin-1, a newly identified anorexigenic peptide, has antioxidant, anti-inflammatory, and anti-apoptotic properties. Brain ischemia-reperfusion induces irreversible damages, especially in the hippocampus area. However, the therapeutic effects of NUCB2 have not been well investigated in cerebral ischemia. This study was designed for the first time to i...

Background: Creatine kinase is a cardiac biomarker that is used for the assessment of ischemic injuries and myocardial infarction. The present study was designed to evaluate effects of oxytocin administration during ischemia and reperfusion periods on CK-MB levels in the coronary effluent of isolated rat heart and the possible role of oxytocin receptor, nitric oxide (NO), prostacyclin and mitoc...
