[ 1 ] - Effect of High Light Level on Sperm parameters in Mice

Background and aims: High light level of natural or artificial sources in some workplaces may be considered as a hazardous physical agent. The present study aimed to assess the effect of light level of 1000 lux on sperm parameters in mice. Methods: The subjects were assessed in two group including 1. Exposed (n= 6; exposed to light level of 1000 lux during 5 eight-hour days), 2. Unexposed ...

[ 2 ] - Production of Nanofibers Containing Magnesium Oxide Nanoparticles for the Purpose of Bioaerosol Removal

The present study aims at investigation of the performance of nanofibrous filter, containing magnesium oxide (MgO) nanoparticles, for bioaerosols removal from the air stream. It synthesizes two types of polyacrylonitrile (PAN) and PAN/MgO nanofibers via electrospinning technique, and investigates the antibacterial properties of the produced nanofibers through disk diffusion. The air containing ...

[ 4 ] - Effects of Co-Exposure to Noise and JP-4 Jet Fuel on Hearing Loss in Rats

Background and Aim: Autotoxic substances such as JP-4 jet fuel can have negative effects on the auditory system by the various means such as cochlear dysfunction. The purpose of this study was to investigate the combined effects of exposure to JP-4 jet fuel and noise on hearing loss in rats, to determine the possible interference effects of these two risk factors on rat auditory system. Methods...

[ 5 ] - COMPARISON OF FILTRATION PERFORMANCE BETWEEN NEAT AND PLASMA-TREATED PAN / MGO NANOFIBERS IN THE REMOVAL OF 10 TO 1000 NM PARTICLES

Introduction: The present study aimed to compare the filtration performance between neat hybrid electrospun nanofibers consisting of polyacrylonitrile (PAN) polymer and magnesium oxide (MgO) nanoparticles and plasma treated ones in removing fine particles from the air stream. Methodology: The upper surface of the nanofibers were processed by cold-plasma with a radio frequency power supply (13....
