functional magnetic resonance imaging (fmri) is a safe and non-invasive way to assess brain functions by using signal changes associated with brain activity. the technique has become a ubiquitous tool in basic, clinical and cognitive neuroscience. this method can measure little metabolism changes that occur in active part of the brain. we process the fmri data to be able to find the parts of br...

background : this study compared the efficacy of two commonly used fractionation schedules for palliative whole brain irradiation in patients with brain metastases, and assessed the association of the radiotherapy therapy oncology group (rtog) recursive partitioning analysis for brain metastases (rpa) to survival with each schedule. methods : patients with multiple (more than three) brain metas...

Introduction: Recent studies suggest that dietary virgin olive oil (VOO) reduces hypoxia-re oxygenation injury in rat brain. We have attempted to determine the effect of dietary virgin olive oil on brain lipidomics and its relationship with brain edema in a rat stroke model. Methods: Five groups, each consisting of 6 male Wistar rats, were studied. The first and second groups (control and s...

the purpose of this paper was to see whether any significant relationship exists among efl learners’ autonomy, left/right brain dominance, and reading comprehension of the academic reading and general reading modules of ielts examination. to this end, 100 female efl learners were randomly selected from those who were attending ielts preparatory courses at a language school in tehran. all partic...

The brain – computer interface (BCI) provides a communicational channel between human and machine. Most of these systems are based on brain activities. Brain Computer-Interfacing is a methodology that provides a way for communication with the outside environment using the brain thoughts. The success of this methodology depends on the selection of methods to process the brain signals in each pha...

The short and long term effects of chromium toxicity on brain catecholamines and acetylcholinesterase levels were investigated. Rats were injected daily with varying amounts of chromium. The short term (2 h) administration of chromium (8 mmol/kg) reduced catecholamines level of cerebellum, mid-brain and brain-cortex by 22.8, 19.4 and 21.2% respectively. Acetylcholinesterase activity was also re...

in this study tsga10 has been demonstrated as a testis-specific human gene that encodes a protein localized in sperm-tail and conserved in ciliary structure. further investigations showed tsga10 signalling and expression during embryogenesis, brain development and some malignancies including brain tumors. given the role of this protein in neuronal development and in certain tumors, it could pot...

Post stroke dementia is one of the most common complications of stroke that is preventable and relatively treatable too. The purpose of the study is comparison between the positive findings in brain CT scan and brain perfusion SPECT. 15 patients who were complicated by dementia after cerebrovascular accident and also 5 patients as a control group enrolled in this study. Brain CT scan and ...

objective(s): brain edema is one of the most serious causes of death within the first few days after trauma brain injury (tbi). in this study we have investigated the role of shilajit on brain edema, blood-brain barrier (bbb) permeability, intracranial pressure (icp) and neurologic outcomes following brain trauma.   materials and methods: diffuse traumatic brain trauma was induced in rats by dr...
