[35S]t-Butylbicyclophosphorothionate or [35S]TBPS is an improved radioligand for the picrotoxinin binding site in rat brain synaptic membranes. The toxic isomers of the hexachlorocyclohexanes, polychlorobornanes, and chlorinated cyclodienes displace [35S]TBPS with a stereospecificity and potency generally correlated with their mammalian toxicity. In a few cases this correlation is improved by c...

introduction: development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. blood brain barrier (bbb) opening is an important part of edema named as vasogenic brain edema. in this study, quantitative alterations of bbb permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. methods: two groups of male rats (ischemic and sh...

Tumors of the Central nervous System (CNS) are a spectrum neoplasms that range from benign lesions to highly malignant and aggressive lesions. Despite multimodal treatment approaches, morbidity mortality high with dismal survival outcomes in these tumors. Moreover, non-specificity conventional treatments substantiates rationale for precise therapeutic strategies selectively target infiltrating ...

Machine learning approaches have been widely used for the identification of neuropathology from neuroimaging data. However, these approaches require large samples and suffer from the challenges associated with multi-site, multi-protocol data. We propose a novel approach to address these challenges, and demonstrate its usefulness with the Autism Brain Imaging Data Exchange (ABIDE) database. We p...

BACKGROUND Previous reports have proposed an association between traumatic brain injury (TBI) and subsequent glioblastoma (GBM) formation. METHODS We used literature searches and radiographic evidence from two patients to assess the possibility of a link between TBI and GBM. RESULTS Epidemiological studies are equivocal on a possible link between brain trauma and increased risk of malignant...

Optic neuritis an inflammatory disorder of the optic nerve inflammation is usually in young’s with symptoms of eye pain and vision loss that occurs is a common symptom of MS. Optic neuritis is one of the first symptoms of MS that observable into disorders in white matter of cerebral cortex. The risk of MS in patients with optic neuritis during 2 years 20% in 15 years, 45-80% is calculated...

Low frequency stimulation (LFS) is a potential alternative therapy for epilepsy. However, it seems that the anticonvulsant effects of LFS depend on its target sites in the brain. Thus, the present study was designed to compare the anticonvulsant effects of LFS administered to amygdala, piriform cortex and substantia nigra on amygdala kindling acquisition. In control group, rats were kindled in ...

Alzheimer's disease is an irreversible and progressive brain disorder that slowly destroys memory and thinking skills and ultimately the ability to do the simplest things and can lead to death. Cholinesterases (ChEs) play an important role in controlling cholinergic transmission, and subsequently, by inhibiting CHEs, acetylcholine levels in the brain are elevated. Coumarins have been shown to e...

BACKGROUND The brain is a common site of recurrence in melanoma patients. Brain recurrence may present as a seizure, hemorrhage, or death. We sought to determine predictors of brain metastases in patients with primary and regional melanoma in order to facilitate targeted screening. METHODS Prospectively maintained databases were used to identify patients treated for local or regional melanoma...

The choroid plexus (CPx) may be an important site of viral dissemination since monocytes and dendritic cells in its stroma are infected with HIV in AIDS patients and since the ratio of CPx to brain infection is more than 2 : 1. In order to see if CPx infection also develops in asymptomatic (ASY) HIV-infected patients, we examined archival formalin-fixed brain and CPx from 14 AIDS and seven ASY ...
