in the mammalian, there are three ncx genes (ncx1, ncx2, ncx3), which their three proteins are differentially expressed in distinct regions of the central nervous system, where they might underlie different physiological and pathophysiological functions. ncx is a nine-transmembrane protein which is distributed in the brain widely. ncx operates in a bidirectional way, and exchanges ca2+ and na+ ...

BACKGROUND Gene therapy may be a promising approach for treatment of brain ischemia, although the efficiency of postischemic gene therapy is not established. Our goal in this study was to examine the effects of gene transfer of interleukin-10 (IL-10), an antiinflammatory cytokine, after induction of brain ischemia. METHODS AND RESULTS Brain ischemia was produced by either photochemical occlus...

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 & objectives: ischemic stroke is the third leading cause of death and disability in most of the human societies. there is no effective treatment due to complexity of the pathophysiological mechanisms. today, more researches are designed to introduce involving factors and new treatment strategies in brain ischemia. the objective of this study is to introduce an experimental model of t...

results the i/r group showed a significant increase in pycnotic (dying) neurons and pretreatment with wc at doses of 500 mg/kg and 1000 mg/kg significantly reduced pycnotic and tunel positive neurons, in a dose dependent manner in ischemic brain cortex. conclusions our findings indicated that wc has neuroprotective effects and is able to reduce histopathological alterations and apoptosis in bra...

objective: the results of the previous studies on the correlation between plasma levels of homocysteine (hcy) and ischemic stroke have been controversial. the aim of the present study is to investigate this correlation meticulously observing risk factors for the ischemic stroke as well as factors affecting the plasma levels of hcy. method: a case-control study was conducted between 2005-2006 wi...

objective(s): some histopathological alterations take place in the ischemic regions following brain ischemia. recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...

BACKGROUND Ischemic stroke is a leading cause of death and long-term disability, and hyperglycemia is believed to aggravate cerebral ischemia. OBJECTIVES To review animal and human studies on the relationship between hyperglycemia and brain ischemia that elucidate some of the mechanisms for the deleterious effect of hyperglycemia. To discuss present and future clinical recommendations for glu...
