Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...

brain injury has a multiple pathophysiology for which there is no definite treatment. in this regard, tissue engineering is one of the probable strategies for repair of damaged tissue. but creating a proper model for testing the engineered products faced some difficulties, specially, when we want to evaluate the effects of a product on the volume of injury. the current brain injury methods coul...

background: with regard to the high prevalence of schizophrenia, research on brain structural changes in this disease has been one of the interesting issues among the medical scientists. in this research, brain mri findings of schizophrenic patients have been compared with non-schizophrenic ones. methods: this study was an analytic-comparative one in which two groups of schizophrenic and non-sc...

Background: Anthropometry is a branch of anatomy. One of the important parts of anthropometry is cephalometry, which is characterized by anatomical dimensions of the head area. The aim of this study was to investigate the relationship between brain volume, weight, and IQ in children. Methods: This descriptive-analytical study was performed on 300 students...

Background: Among different mechanisms, oxidative stress has a possible role in neural injury in cerebrovascular events. Objectives: Assessment the oxidants-antioxidants imbalance in ischemic and hemorrhagic strokes. Materials and Methods: Serum level of malondialdehyde, the main marker of lipid peroxidation, and total antioxidant capacity were measured in a group of 48 stroke patients consis...

objectives in this study, we aimed to investigate the changes in brain lipidomics following prolonged and intermittent ischemic preconditioning. materials and methods two groups underwent bilateral common carotid artery occlusion either intermittently (for 3 continuous periods within a timeframe of 20 minutes, releasing 3 consecutive times, yielding a total of 9 minutes (intermittent bilateral ...
