Introduction: Cerebral ischemia and reperfusion causes physiological and biochemical changes in the neuronal cells that will eventually lead to cell damage. Evidence indicates that exercise reduces the ischemia and reperfusion-induced brain damages in animal models of stroke. In the present study, the effect of exercise preconditioning on brain edema and neurological movement disorders followin...

Objective(s): Cerebral ischemia/reperfusion causes complex pathological mechanisms that lead to brain tissue damage. Usnic acid is a lichen secondary metabolite that has many different biological properties including anti-inflammatory and anti-oxidant activities. Therefore, the objective of the current study was to investigate the neuroprotective effects of usnic acid ...

background: it is well known that the hippocampus, the ca1 pyramidal cells in particular, is selectively vulnerable during global cerebral ischemia. recently, it is observed that pentoxifylline has a neuroprotective effect. this study explored the pharmacological relationship between ischemia-induced cell death of the hippocampus and the efficacy of a vasodilator agent (pentoxifylline) in the p...

Introduction: Cerebral ischemia-reperfusion causes complex pathological mechanisms that lead to tissue damage, such as neuronal apoptosis. Usnic acid is a secondary metabolite of lichen and has various biological properties including antioxidant and anti-inflammatory activities. This study aimed to investigate the neuroprotective effects of usnic acid on apoptotic cell death and apoptotic-relat...

objective: oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. the beneficial effects of antioxidant nutrients, as well as complex plant extracts, on cerebral ischemia-reperfusion injuries are well known. this study was conducted to determine the effects of the hydro-alcoholic root extract of withania coagulans on ca1 hippocampus oxidative damages followin...

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: Nitric oxide synthase (NOS) activity is increased during hypertension and cerebral ischemia. NOS inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (BBB) disruption and cerebral edema formation during stroke in acute hypertension. Here, we investigated the role of NOS inhibition in progression of edema formation and BBB d...
