traumatic brain injury resulting road accidents create damage to the brain. the severe brain injury may cause extensive tissue loss of several parenchyma which results in cavities due to primary destruction and secondary injuries such as ischemia and inflammation. recent findings suggest that neuronal precursors in the adult mammalian brain can be a therapeutic target in ischemic brain injuries...

objective: it is generally agreed that most of the phenomena observed during brain ischemia and reperfusion can be explained by the damage to membrane structure. oxidative stress is resulted in an imbalance between high consumption of oxygen and low levels of endogenous antioxidants. it is known that gallic acid (ga) is a strong antioxidant. the present study was carried out to evaluate the eff...

  Background : Brain injury by transient complete global brain ischemia (cardiac arrest) and regional incomplete brain ischemia (ischemic stroke) afflicts a very large number of patients with death or permanent disability. Recent studies suggest that olive extracts suppress inflammation and reduce stress oxidative injury.   Methods: The aim of the study was to evaluate the effect of dietary Oli...

conclusions the analysis of the pro-apoptotic gene to anti-apoptotic gene expression ratio (bad /bcl-xl) confirmed that expression of the pro-apoptotic gene significantly decreased (p value ˂ 0.001) under the ischemia/reperfusion condition. in contrast, the expression of the anti-apoptotic gene increased after administration of fk-506 (p value ˂ 0.001). results the quantitative results of real-...

OBJECTIVES Recent studies have reported that cis element decoy oligodeoxynucleotides against nuclear factor-kappa B block the activation of genes that mediate ischemic injury. To improve brain protection during circulatory arrest in cardiac surgery, we evaluated the efficacy of nuclear factor-kappa B decoy oligodeoxynucleotides in preventing neuronal damage after global brain ischemia. METHOD...

ischemic brain injury involves a complex sequence of excitetoxic and oxidative events. metformin is proposed as one of the potential candidates for returning the body to its basic homeostasis in ischemic situations. metformin can either protect or damage cells by activating amp-activated protein kinase (ampk) and its downstream factors so, it has a dual role in the cerebral ischemia context, bu...

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...

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...
