Oxidative stress during ischemia-reperfusion acute renal failure (IR-ARF) was noninvasively evaluated with in vivo electron paramagnetic resonance (EPR) imaging. Female ICR mice underwent left nephrectomy and 30-min ischemia-reperfusion of the right kidney. Oxidative stress was evaluated as organ reducing activity
Acute extremity arterial occlusion requires prompt revascularization. Delayed revascularization induces ischemia-reperfusion injury in the skeletal muscle. Organ injury-induced oxidative stress is widely reported, and oxidative stress is heavily involved in ischemia-reperfusion injury. This study aimed to evaluate oxidative stress in
Nitroxide radicals are paramagnetic contrast agents, used in magnetic resonance imaging (MRI), that also exert antioxidant effects. Participating in cellular redox reactions, they lose their ability to provide contrast as a function of time after administration. In this study, the
Reactive oxygen species (ROS) are reportedly associated with gastric ulcer. We previously reported the use of an in vivo 300-MHz electron spin resonance (ESR) spectroscopy/nitroxyl probe technique to detect *OH generation in the stomachs of rats with gastric ulcers induced
In vivo electron paramagnetic resonance (EPR) with nitroxyl spin probes has been used for the evaluation of in vivo free radical reactions and redox status in living animals. The aim of this study was to clarify the location of free
