conclusions in conclusion, in spite of usually benign features, chronic otitis media may lead to serious complications such as brain abscess. every effort should be made for microbiological diagnosis of the causative pathogen(s) for appropriate antibiotic treatment. introduction brain abscess is a rare life-threatening focal intracerebral infection. the etiology of brain abscess depends on trau...

introduction : brain-based teaching is the implementation of principles and strategies derived from an understanding of the brain to enhance learning. authors in this research investigated the effects of brain-based training on learning and retention of life skills in adolescents. methods: this experimental study was designed as pre- post-test with a control group model and was conducted at the...

background and objective: gliomas are the most common primary brain tumors. despite therapeutic advances, the majority of gliomas do not respond to either chemo or radiotherapy. cd117, the gene product of c-kit has been expressed in cells of glial tumors. because gastrointestinal stromal tumors (gists) that express cd117 respond dramatically to treatment with tyrosine kinase inhibitors, identif...

background: carbon monoxide (co) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. magnetic resonance imaging (mri) has a well-recognized role in assessment of the severity of brain damage caused by co poisoning. in this study, we aimed to present and analyze the structural abnormalities in the brain mri and especially in diffusion weighted mri (dwi) images in ...

this is a case series which report the clinical results of decompressive craniectomy in 4 patients with dilated pupils secondary to traumatic brain injury and postoperative edema. between 2011 and 2012, four patients, 3 males and 1 female, aged between 35 and 64 with mean age of 50.1 ± 8.9 years, underwent decompressive craniectomy due to brain traumatic edema. the follow up period ranged betwe...

acetylcholinesterase (ache) is a large glycoprotein that, aside from its known cholinolytic activity, co-exists with other transmitter systems and possesses other functions. in the present study, the effects of short-term rapid-eye-movement sleep deprivation (rem-sd) on ache activity in the anterior hypothalamic area have been investigated. using the flower-pot method, adult male albino rats we...

background: brain is the most important organ as it controls and co- ordinates all the activities of our body. reports on neuroethological investigations in mice particularly associated with learning and memory after radiation exposure are very scanty. hence, present investigation is an attempt to examine the effects of low dose tritiated water (hto) acute exposure on adult swiss albino mice in...

Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...
