the use of deep brain stimulation in psychiatric disorders has received great interest owing to the small risk of the operation, the reversible nature of the technique, and the possibility of optimizing treatment postoperatively. currently deep brain stimulation in psychiatry is investigated for obsessive-compulsive disorder, gilles de la tourette’s syndrome and major depression. this presentat...

Objective(s): Studies have mainly assessed the effect of hyperglycemia on18F-fluorodeoxyglucose (FDG) uptake in the brain. In this study, we assessed the FDG uptake of the brain not only in normo- and hyperglycemia but also in hypoglycemia to compare the effect of various blood glucose levels on regional FDG uptake in the brain. Methods: </...

Medicinal plants have attracted global attention due to their high levels of antioxidant components for prohibiting or improving various diseases including brain and memory disorders. This study was designed to investigate if the antioxidant effect of Sidr (Zizyphusspina-christi) extract can help to improve the scopolamine induced impairment of memory in Wistar rats. Animals were randomly...

The descriptive statistic known as "effect size" measures the distinguishability of two sets of data. Distingishability is at the core of diagnosis. This article is intended to point out the importance of effect size in the development of effective diagnostics for mild traumatic brain injury and to point out the applicability of the effect size statistic in comparing diagnostic efficiency acros...

traumatic brain injuries may cause some neurological deficits, such as altered level of consciousness or coma, sensory-motor dysfunction, and seizure attacks. the neuroprotective effect of progesterone and erythropoietin has been shown in different types of brain injuries and cerebral ischemia. this study aims to evaluate the probable additional neuroprotective effects of progesterone and eryth...

Introduction: It has been suggested physical exercise exerts neuroprotection in traumatic brain injury&nbsp;(TBI). However little information is available about the effect of endurance exercise on brain edema, inflammation and oxidant activity in diffuse TBI. Therefore, we investigated the prophylaxis effect of endurance training against&nbsp;oxidative damage, inflammation and brain edema assoc...

the activity of aspartate aminotransferase a vitamin b6 containing enzyme was measured in the laysed synaptosomes prepared from rat brain, during development. administration of vitamin b6 increased the enzyme activity throughout development. the stimulating effect of this vitamin was prevented when the animals were previously treated with d-penicillamine. however, penicillamine alone had no eff...

Introduction: Brain weight and cranial capacity are important parameters in the study of racial/ ethnic differences. This study was done to determine the effect of ethnicity on the female’s brain weight in Northern Iran. Methods: Brain weight was estimated using linear (Lee–Pearson’s) formula in 410 normal 17–20 year old (207 native Fars and 203 Turkman) females in northern Iran. Dimension...

Background: The aging process is associated with a progressive deterioration of tissues and organs. Apoptotic cell death has been known as a possible causal factor in age-related pathologies. Therefore, this study was conducted to assess the effect of regular high-intensity interval exercise on some apoptotic factors in the brain tissue of aged female rats. Materials and Methods: In this exper...
