Aims:Memory deficit is the most visible symptom of cerebral ischemia. The hippocampus is sensitive against cerebral ischemia. Oxidative stress and inflammation are involved in the pathological process after cerebral ischemic injury. Paroxetine has anti-oxidative and anti-inflammatory effects. In this study the effect of paroxetine on memory deficit after cerebral ischemia was investigated. Meth...

Background and Objective: Ischemia in the brain of rats causes intensive neural injuries leading to learning and memory disorders in addition to pain. Ellagic acid is a polyphenol compound with antioxidant properties which is found in fruits like pomegranate, blackberry and all types of mulberry. The objective of this study was to investigate the effect of 14-day prescription of different doses...
Behavioral studies in monkeys and humans suggest that systematic and variable errors of memory-guided saccades reflect distinct neuronal computations in primate spatial memory. We recorded memory-guided saccades with a 2-s delay in three patients with unilateral ischemic lesions of the frontal eye field and in three patients with unilateral ischemic lesions of the frontal eye field and the dors...
Therapeutics for cerebral ischemia/hypoxia, which often results in ischemic stroke in humans, are a global unmet medical need. Here, we report that bryostatin-1, a highly potent protein kinase C (PKC) activator, interrupts pathophysiological molecular cascades and apoptosis triggered by cerebral ischemia/hypoxia, enhances neurotrophic activity, and induces synaptogenesis in rats. This postische...
چکیده: هدف: هدف از پژوهش حاضر مقایسه حافظه (کوتاه مدت، بلند مدت و بصری) در بیماران مبتلا به دیابت نوع 2 و افراد سالم می باشد. روش: روش پژوهش از نوع علی مقایسه ای است. جامعه آماری این تحقیق را کلیه بیماران مبتلا به دیابت نوع 2 ساکن شهرستان پارس آباد و روستاهای اطراف آن تشکیل می دهند. از بین این جامعه، 40 نفر از بیماران مراجعه کننده به پزشکان متخصصین داخلی و پزشکان خانواده که در شهرستان پارس آبا...
Rats exposed to 30 minutes of four-vessel occlusion reliably develop severe bilateral CA1 hippocampal injury; under certain conditions of radial maze training, such rats perform the reference memory component as well as controls yet perform the working memory component worse than controls. Reference memory is thought to depend on invariable and working memory on variable spatial information. We...
Introduction: During menopause, which is a part of the aging process in women, the level of sex hormones decreases, which causes problems such as memory impairment and cognitive functions. One of the treatment options for these disorders is hormone therapy, which has several side effects. The present study investigated the effect of remote ischemic conditioning (RIC) technique on memory improve...
The present study has been designed to investigate the modulatory role of dichlorobenzamil a Na(+)/Ca(2+) exchanger inhibitor in ischemic post-conditioning-induced neuroprotection in mice. Bilateral carotid artery occlusion followed by reperfusion, produced a significant rise in cerebral infarct size along with impairment of memory and motor coordination. Ischemic post-conditioning involving th...
