Abstract Pediatric low-grade glioma incidence has been rising in the U.S. over last 20 years, concurrent with a rate of obesity both adult and pediatric populations. Recently, children obese mothers have demonstrated to increased rates several tumors, including brain tumors. Importantly, is driven large part by diet, given abundance accessibility high-fat, high-sugar food choices. High-fat diet...
Note Primary CNS tumors constitute a spectrum of pathological entities each with a distinct natural history that reflects the sequential accumulation of genetic lesions and the deregulation of growth-factor signalling pathways during neoplastic transformation. For simplicity, CNS tumors may be classified as GLIOMAS or NONGLIOMAS (see Table 1 which provides a summary of 2007 World Health Organiz...
Brain tumors are the most common solid tumors in childhood. Glioblastoma multiform (GBM) is the second most common primary brain tumor in adults. It usually affects the cerebral hemispheres of adults at the 6th or 7th decade of life. In comparison to adult population, GBM is rare in pediatrics and accounts for approximately 3% of all pediatric brain tumors. Pediatric glioblastoma was defined as...
The effects of potential neurohormones on the intracellular concentrations of adenosine 3':5'-cyclic monophosphate have been examined with three clonal lines of cultured glial tumors. In all cases, norepinephrine and isoproterenol produced striking elevations of the intracellular concentrations of the cyclic nucleotide. The response was mediated by a beta-adrenergic receptor. This effect is hyp...
Types of glioma brain tumors and genetic alterations in signaling pathways in them Background & Objective: Glioma is a common type of primary brain tumor originating in the glial cells that surrounds and supports neurons in the brain. These tumors arise from three different types of cells that are normally found in the brain: astrocytes, oligodendrocytes, and ependymal cells, accordingly types ...
Abstract Symptomatic presentation of patients with intra-cranial malignancy is frequently non-specific and differentiating such from those benign conditions challenging. Accordingly, GBM presents as a medical emergency more than any other common cancer, implying that effective strategies for rapid simple diagnostic stratification are urgently required. Here we describe the detection glial malig...
Neuroglial tumors contain both neuronal and glial elements and are the slowest growing CNS tumors, we report our experience in MR proton single voxel and CSI spectroscopy in 6 neuroglial tumors: gangliocytoma(1), gangliogliomas(4) and DIG(1), all classified as favorable low grade WHO grade I tumors. These tumors all have good prognoses but are rare entities, with the commonest, gangioglioma, re...
