background: limited data available about the mechanisms of dysphagia and areas involving swallow after brain damage; accordingly it is hard to predict which cases are more likely to develop swallowing dysfunction based on the neuroimaging. the aim of this study was to investigate the relationship between brain lesions and dysphagia in a sample of acute conscious stroke patients. materials and m...

results in all groups ischemic changes were apparently observed in hippocampus ca1 neurons. in two-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 14.9% and 23.2%, respectively. in four-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 7.6% and 44.9% (p < 0.0001), respectively. background an appropriate animal m...

traumatic brain injury (tbi) is an important cause of death and disability in young adults ,and may lead to physical disabilities and long-term cognitive, behavioral psychological and social defects. there is a lack of definite result about the effect of thyroid hormones after traumatic brain injury in the severity and no data about their effect on mortality of the injury. the aim of this study...

background : the brain is a rare site of metastases from ovarian cancer. limited data are available on prognostic factors, standard treatment, and survival. knowledge of clinical prognostic factors would help the management of patients with brain metastases. the aim of this study is to evaluate the impact of clinical factors and treatment modalities on survival in patients with brain metastases...

Catecholamine is a group of neurotransmitters that is believed to be responsible for the normal function of animal brain. Physiological and behavioral changes of human body have been reported due to the damage of the brain function following lead exposure. Due to the assumption of lead disposal in brain tissue with two year for its half-life, which results in alteration of brain function, we in...

In previous studies, the neuroprotective effect of progestrone in diffuse traumatic brain injury has been shown. This study used mifepristone (RU-486), a potent progesterone receptor antagonist, to evaluatethe hypothesis that the neuroprotective effect of progesterone in traumatic brain injury is mediated by the progesterone receptors. The ovariectomized rats were divided into 6 groups. Brain i...

objectives: this paper reviews the current literature on acquired brain injury (abi) with a focus on abi burden, importance of community integration, and community integration definitions suggested by the literature. methods: literature review results: acquired brain injury (abi) is referred to a diverse range of disabilities resulted of injury in different parts of the brain. people with abi a...
