ABSTRACT Background: High resolution CT scan has made early diagnosis of intraventricular hemorrhage (IVH) easier. Posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the CT scan. Methods: 904 patients were admitted in the NSICU from March 2001 to March 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (GCS le...

background and aims: there are different causes for brain death including head trauma, cerebrovascular accidents and intracranial space-occupying lesions. the present study was aimed to determine the causes of brain death in chahar mahal and bakhtiari province due to high turnover of trauma in this area during 2003 to 2013. methods: this study was based on routine data and was conducted on all ...

background : studies have emphasized on the frontal eeg  symmetry as a mediator of emotional states. this research was aimed to examine the overall and asymmetric activities of the brain lobes under the affective states. methods : a coupling eeg was recorded in an eye closed awakened condition from 40 right handed female students under the baseline and affective states. results : bilaterally de...

The processing of brain spectrin (fodrin) by calcium-dependent proteases at the postsynaptic membrane has been postulated to be one of the central molecular mechanisms underlying long-term potentiation (LTP). The effect of such processing on the structure and function of brain spectrin, and on spectrin's ability to organize or otherwise regulate receptor function remains unclear. To address the...

The cerebral endothelium is an active interface between blood and the central nervous system. In addition to being a physical barrier brain, also actively regulates metabolic homeostasis, vascular tone permeability, coagulation, movement of immune cells. Being part blood–brain barrier, endothelial cells brain have specialized morphology, physiology, phenotypes due their unique microenvironment....

Abstract: Intranasal drug delivery is a promising route for directly to the brain acute or chronic treatments. A direct offers rapid approach delivering drugs central nervous system without using parenteral route. Carmustine nitrosourea used treat tumors, multiple myeloma, lymphoma, and Hodgkin’s disease but its use limited by very little half-life in body fluids. The nanoparticles have shown g...

•Brain metastasis is an extremely rare secondary site of ovarian cancer metastasis.•Serous borderline tumor with brain metastasis has not been previously reported.•This is a rare case of brain metastasis in a patient with advanced serous borderline tumor.

Metastasis is the relentless pursuit of cancer to escape its primary site and colonize distant organs. This malignant evolutionary process is biologically heterogeneous, yet one unifying element is the critical role of the microenvironment for arriving metastatic cells. Historically, brain metastases were rarely investigated because patients with advanced cancer were considered terminal. Fortun...

background & importance: our study was performed based on the first case, reported in english, of a patient with three contemporary lesions, an extra-axial malformation and two vascular ones. case presentation: a 62-year-old man referred to our clinic due to right hand tremor associated to a slowing of idea-forming function and movements. the neuroradiological evidence showed a right fronto-tem...

background: palliative whole brain radiotherapy (wbrt) has been the standard treatment for brain metastases. ionizing radiation is known to be one of the most potent cataractogenic agents. we aimed to evaluate two different radiotherapy techniques with respect to the doses received by the organs at risk (oar) in patients with brain metastasis who undergone wbrt. materials and methods: ten conse...
