Early Exposure to Environmental Toxin Contributes to Neuronal Vulnerability and Axonal Pathology in a Model of Familial ALS
SOD1 ALS Neurotoxin Axonopathy NMJ Gliosis Toxicity
2013/1/30
Adult onset amyotrophic lateral sclerosis (ALS) arises due to progressive and irreversible functional deficits to the central nervous system, specifically the loss of motor neurons. Sporadic ALS causa...
Evaluation of Ginkgo Biloba Extract on Hematological Changes Affected with Hazards of Electromagnetic Field Exposure
ginkgo biloba free radicals EMF-viscosity of blood dielectric properties of hemoglobin
2009/10/26
The aim of the present work is to study if the GBE 761 (Ginkgo biloba leaves extract) which is beneficial in arterial disease owing to its vasodilator and blood flow acts against the hazards of exposu...
Effects of dielectric permittivities on skin heating due to millimeter wave exposure
dielectric permittivities skin heating millimeter wave exposure
2010/2/25
This paper analytically clarified the effects of dielectric permittivities on the thermally steady state temperature elevation and the temperature difference in the skin of a one-dimensional three-lay...
Response of tibialis anterior tendon to a chronic exposure of stretch-shortening cycles: age effects
tibialis anterior tendon a chronic exposure stretch-shortening cycles
2010/2/25
The chronic protocol enhanced the elastic stiffness of young tendon and the loads in both the young and old tendons. The old exposed tendons were found to exhibit higher load capacity than their young...
CORTICAL SPREADING DEPRESSION ELICITED IN RAT BRAIN AFTER EXPOSURE TO MICROWAVE FROM GSM MOBILE PHONE
CORTICAL SPREADING DEPRESSION ELICITED RAT BRAIN AFTER MICROWAVE FROM GSM MOBILE PHONE
2009/4/20
The aim of the present work is to evaluate possibility of microwave emitted by cellular phone that can elicit cortical spreading depression (CSD) in rat brain and studying the characteristics of t...
Sulfur mustard (mustard gas) is the most important vesicant agent, and among all chemical warfare agents it has caused the greatest number of casualties of particularly, during the Iran–Iraq War (198...
A novel application of capnography during controlled human exposure to air pollution
controlled human exposure air pollution
2010/2/26
We showed that a customized setup for the acquisition and processing of the capnographic wave signal, interfaced with HEF was stable and repeatable. Thus, we expect that analysis of capnographic waves...
Lead exposure impairs NMDA agonist-induced no production in pyramidal hippocampal cells
Lead acetate ACBD NMDA agonist Pyramidal cell Nitric oxide Culture
2010/2/1
Chronic exposure to Lead (Pb) affects neural functions in central nervous system (CNS) particularly the learning and memory. On the other hand, alteration of calcium level in the CNS results in activa...
Optimization of Sample Preparation for 1-Hydroxypyrene as a Major Biomarker of Exposure to Polycyclic Aromatic Hydrocarbons Prior to High Performance Liquid Chromatography
Liquid liquid extraction 1-Hydroxypyrene PAHs
2010/2/1
Urinary 1-hydroxypuren (1-OHP) is commonly used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons (PAHs). For evaluation of human exposure to s...
An In-Vitro Study on the Release of Fluoride from Two Restorative Materials and Their Rechargeability after Exposure to Daily 1000 ppm Fluoride
Fluoride release Fluoride uptake Resin modified glass ionomer
2010/2/8
Statement of Problem: Since the fluoride releases from materials with the property of releasing fluoride are decreasing gradually, it seems that probably the material rechargeability is more important...
Review and standardization of cell phone exposure calculations using the SAM phantom and anatomically correct head models
cell phone exposure calculations the SAM phantom and anatomically correct head models
2010/3/1
We reviewed articles using computational RF dosimetry to compare the Specific Anthropomorphic Mannequin (SAM) to anatomically correct models of the human head. Published conclusions based on such comp...
