Objectives: To explore the diagnostic utility of glial fibrillary acidic protein (GFAP), S100β protein and dDimer for differentiation between cases of acute stroke compared to CT findings as a gold-standard diagnostic modality. Patients & Methods: The study included 80 patients; 51 males and 29 females with mean age of 49.6±6.8 years. Mean time lapsed since occurrence of symptoms till sampling ...

INTRODUCTION Glial fibrillary acidic protein (GFAP) may serve as a serum marker of traumatic brain injury (TBI) that can be used to monitor biochemical changes in patients and gauge the response to treatment. However, the temporal profile of serum GFAP in the acute period of brain injury and the associated utility for outcome prediction has not been elucidated. METHODS We conducted a prospect...

PURPOSE In an attempt to identify Müller cell-specific promoters and to better understand the gene regulatory mechanisms in retinal glial cells, the expression of the glial fibrillary acidic protein (GFAP) gene was studied in Müller cell cultures and in GFAP-enhanced green fluorescent protein (EGFP) transgenic mice. METHODS A transfection assay of GFAP-luciferase constructs carrying a series ...

Prion protein (PrPsc) which accumulates in the brains affected with subacute spongiform encephalopathies (SSE) is altered isoform of normal, cellular isoform (PrPc), and PrP deposition is accompanied with spongiosis and astrogliosis. To find the amounts of PrP and GFAP transcripts during progression of experimental Creutzfeldt-Jakob disease we performed comparative RT-PCR on the terminally sick...

Previous reports of increases in glial cell number and expression of glial fibrillary acidic protein (GFAP) in stimulated brain regions or epileptic tissue have implicated a role for increases in extracellular potassium concentration ([K+]o) in glial reactions. We examined the effects of altered [K+]o on DNA and protein syntheses and GFAP expression of cultured glial cells isolated from the pos...

BACKGROUND AND PURPOSE The HIV-envelope glycoprotein Gp120 is involved in neuronal injury and is associated with neuro-AIDS pathogenesis in the brain. Endocannabinoids are important lipid ligands in the CNS regulating neural functions, and their degeneration is controlled by hydrolysing enzymes such as the fatty acid amide hydrolase (FAAH). Here, we examined whether in vivo genetic deletion of ...

Retinal neovascularization (NV) is a major cause of blindness in ischemic retinopathies. Previous investigations have indicated that ischemia upregulates GFAP and PDGF-B expression. GFAP overexpression is a hallmark of reactive gliosis (RG), which is the major pathophysiological feature of retinal damage. In addition, PDGF-B has been implicated in proliferative retinopathies. It was the aim of ...

Premature return to play (RTP) following sports-related concussion (SRC) is associated with significant morbidity including risk of neurological and non-neurological injury, persistent post-concussion symptoms chronic deficits. Assessing athletes for RTP critical but these decisions are currently based on clinical assessments that subject bias symptomatic reporting rely compliance. An objective...
