Brain tumours are masses of abnormal cells that can grow in an uncontrolled way the brain. There different types malignant brain tumours. Gliomas from glial and identified as astrocytoma, oligodendroglioma, ependymoma. We study a mathematical model describes glia-neuron interaction, glioma, chemotherapeutic agent. In this work, we consider drug sensitive resistant glioma cells. show continuous ...

Introduction: The purpose of this study was to develop a statistical model for prediction of radiation induced sensorineural hearing loss (SNHL) induced by radiotherapy in patients with brain tumors.   Materials and Methods: CT scan of 18 patients (10 males and 8 females) with brain tumor who were referred to Radiation Center of Milad Hospital in Isfahan in 2...

Background: Probiotics are microorganisms that may influence brain function via altering brain neurochemistry. New research evidence suggests that probiotic bacteria might protect tissue damage through diminishing the production of free radicals and/or inflammatory cytokines. Therefore, this study was designed to evaluate the effects of probiotic bacteria on the prevention or reduction of brain...

Objective(s): Amyloid β plaques, in Alzheimer’s disease, are deposits in different areas of the brain such as prefrontal cortex, molecular layer of the cerebellum, and the hippocampal formation. Amyloid β aggregates lead to the release of cytochrome c and finally neuronal cell death in brain tissue. hCG has critical roles in brain development, neuron differentiation, and function. Therefore, we...

Aim: Oxidative stress plays a crucial role in the pathophysiology of ischemic stroke. Since water-solublefullerene derivatives act as the potent scavenger of oxygen free radicals in biological systems, we aimedto investigate the possible protective effects of fullerol nanoparticles on brain infarction and edema intransient model of focal cerebral ischemia in rat.Materials & Methods: Experiment ...

introduction: plastination is a unique technique for preservation of biological specimens used for teaching purposes. the protocol of flexible sheet plastination includes fixation, slicing, dehydration, force impregnation, casting, and curing (hajian, rabiei, fatollahpour & esfandiary, 2008). the procedure is done by using p87 flexible unsaturated polyester resin and provides heavy, gross, frag...
