Neuronal morphology is highly sensitive to ischemia, although some re-organization may promote neuroprotection. In this study we investigate the role of actin regulating proteins (ARP2, ARP3 and WAVE-1) and their role in rapid ischemic tolerance. Using an established in vitro model of rapid ischemic tolerance, we show that WAVE-1 protein levels are stabilized following brief tolerance inducing ...

Introduction: Ischemic preconditioning (IPC) is an endogenous phenomenon that can induce ischemic tolerance (IT) in variety of organs such as brain. In this study, we examined the intermittent and prolonged dose of normobaric hyperoxia (HO) on neurologic deficit scores, infarct volume, and catalase activity. Material and Method: The rats were divided to four main groups. First two main groups w...

Two types of ischemic tolerance in the brain, rapid and delayed, have been reported in terms of the interval between the conditioning and test insults. Although many reports showed that delayed-phase neuroprotection evoked by preconditioning is evident after 1 week or longer, there have been a few investigations about rapidly induced tolerance, and the reported neuroprotective effects become am...

objective: ischemic preconditioning (ipc) is an endogenous phenomenon that can induce ischemic tolerance (it) in variety of organs such as brain. in this study, we examined the intermittent and prolonged normobaric hyperoxia (ho) on neurologic deficit scores, infarct volume, and superoxide dismutase activity. materials and methods: the rats were divided to four main groups. first two main grou...

Background: Cardiac complications after myocardial infarction are believed to be worse in the presence of comorbidities; we tested whether experimentally induced prolonged uremia exacerbated myocardial necrosis in a rabbit preparation of ischemia-reperfusion injury. In addition, we examined if treatment with an angiotensin converting enzyme inhibitor (Enalapril, ENA, 3 mg/Kg, IV) could reduce p...
