Background and Aim: Considering the great advances and extensive use of cell phones and its effects on the human communications and interactions, investigation of potential negative effects of cell phones on the users' health is necessary. The aim of this study was to determine the effect of the distance between cell phones and brain tissue on the temperature of the central and gray matters of ...
Introduction: Tissue engineering by using decellularized tissues has been attracted attention of researchers in the regenerative medicine. Extra cellular matrix (ECM) is a secretory product of cells inside the tissues with supportive and regulatory function for homing cells. ECM contains glycosaminoglycans (GAGs) and fibrous proteins. Each particular tissue has its unique ECM, especially brain,...
Background: It is well known that the development of brain oxidative stress is one of the most serious complications of arterial hypertension that evokes brain tissue damage. The aim of this study was to examine the effects of atorvastatin treatment (20 mg/kg/day), as an antioxidant, to prevent the brain tissue oxidative stress in the hypertensive (HTN) rats. Methods: Experiments were performed...
background: the aim of this work was to establish how well gel dosimeters performed, as substitutes for brain tissue compared with standard phantom materials such as water, polymethyl-methacrylate (or pmma), a150 plastic and te- liquid phantom material for dosimetry of neutron beams in boron neutron capture therapy. materials and methods: thermal neutron fluence, photon dose and epithermal neut...
Introduction: A relationship between epileptic seizures and brain tissue oxidative damage has been suggested. Ocimum basilicum (O. basilicum) has been shown to have beneficial effects including hypnotic and protective against tissue oxidative damage. The present study was designed to evaluate the effects of O. basilicum hydro-alcoholic extract on oxidative damage of brain tissue following s...
brain mr images tissue segmentation is one of the most important parts of the clinical diagnostic tools. pixel classification methods have been frequently used in the image segmentation with two supervised and unsupervised approaches up to now. supervised segmentation methods lead to high accuracy but they need a large amount of labeled data, which is hard, expensive and slow to obtain. moreove...
background: diabetes is considered as one of the most common chronic disease. studies show that diabetes decreases the activity of antioxidant enzymes. the purpose of this study was to examine the effect of the alcoholic extract of juglans regia leave on brain antioxidant enzymes in streptozotocin-induced diabetic rats. materials and methods: in this study, adult male wistar rats (n=40, weight ...

Materials and Methods: Thermal neutron fluence, photon dose and epithermal neu...
introduction: repetitive cortical spreading depression (csd) can lead to cell death in immature brain tissue. caspases are involved in neuronal cell death in several csd-related neurological disorders. yet, whether repetitive csd itself can induce caspase activation in adult or juvenile tissue remains unknown. inducing repetitive csd in somatosensory cortices of juvenile and adult rats in vivo,...
Purpose: Blast-induced traumatic brain injury (bTBI) is one of the causes of death or permanent invalidity which can occur unexpectedly in both military and civilian populations. This study set out to conduct a combined Eulerian-Lagrangian computational analysis of the interaction between a single planar blast wave and a human head in order to assess the extent of intracranial shock w...
