A series of tests have been conducted to investigate fatigue damage characterization in corroded welded steel plates using structural health monitoring (SHM) techniques. Acoustic Emission (AE) is a non-destructive testing (NDT) technique with potential applications for locating and monitoring fatigue cracks in service. In the present work, AE is implemented to characterize damage during crack e...

introduction: numerous evidence indicates the involvement of insulin and k atp channel blockers in brain functions such as memory. materials & methods: in this study, by applying light (h & e staining) and scanning electron microscopies, we investigated the effect of intrahippocampal injection of insulin, glibenclamide experimental diabetic rats. may these reverse the cellularimpairment, and pr...

Organ damage after reperfusion of previously viable ischemic tissues is defined as ischemia/reperfusion injury. The pathophysiology of ischemia/reperfusion injury involves cellular effect of ischemia, reactive oxygen species and inflammatory cascade. Protection against ischemia/reperfusion injury may be achieved by preconditioning or postconditioning. In this review, we discuss basic mechan...
