Liver ischemia preconditions the heart against ischemia-reperfusion arrhythmias
Objective(s):This study aimed to examine the hypothesis that an antiarrhythmic effect might be obtained by ischemic preconditioning of the liver, and also to characterize the potential underlying mechanisms. Materials and Methods: Male Wistar rats were anesthetized by thiopental sodium (50 mg/kg, IP) followed by IV injection of heparin (250 IU). Remote ischemic preconditioning (RIPC) was induce...
متن کاملIschemia/Reperfusion Injury
This study assessed gentamicin's effects on ischemia/reperfusion renal injury to better understand when and how it worsens postischemic acute renal failure. Rats were subjected to 25 minutes of renal pedicle occlusion with and without preischemic (15-minute) or postischemic (15-minute or 8-hour) gentamicin treatment (100 mg/kg, by itself a subtoxic dose). Gentamicin's impact on hypoxia/reoxygen...
متن کاملIschemia and Reperfusion
Calcium has been implicated as a mediator of cell injury in ischemia and reperfusion, but direct measurements of Ca2+ are required to refine this idea. We used nuclear magnetic resonance spectroscopy and the Ca2+ indicator SF-BAPTA to measure [Ca21]; in perfused ferret hearts. Several lines of evidence are presented to show that loading with the acetoxymethyl ester of 5F-BAPTA is not significan...

متن کاملHepatic ischemia-reperfusion injury.
24 Interferon regulatory factor-1 (IRF1) is a nuclear transcription factor that induces inflammatory 25 cytokine mediators and contributes to hepatic ischemia-reperfusion injury (I/R). Currently, no 26 strategies to mitigate IRF1-mediated liver damage exist. Interferon regulatory factor 2 (IRF2) is a 27 structurally similar endogenous protein that competes with IRF1 for DNA binding sites in IRF...
