Investigating the Effects of Exposure to Continuous White Noise on SLC26A4 Gene Expression Levels in Male Rat Cochlea

Background and purpose: Irreversible damage to the inner ear is known as noise-induced hearing loss (NIHL). Exposure to excessive noise can affect the expression of genes in molecules involved in development of NIHL. SLC26A4 gene or PDS is responsible for causing both syndromic and non-syndromic deafness and is located at DFNB site. The aim of this study was to investigate the expression level ...

Special Issue on The Challenging Issues of the Health Effects of Exposure to High Levels of Natural Radiation

The effects of gestational and lactational exposure to Nonylphenol on c-jun, and c-fos expression and learning and memory in hippocampus of male F1 rat

Objective(s): To investigate the effects of Nonylphenol (NP) in pups from dams exposed during gestational and lactational periods on immediate early genes (c-jun, c-fos) in hippocampus and the learning and memory of F1 rats. Materials and Methods: Twenty eight pregnant dams, stratified by pregnancy date, were randomly assigned into 4 groups, which were gavaged with NP at the doses of 50 mg/kg/d...

Neurobehavioral Effects of Prolonged Exposure to Solid Air Freshener in Mice

Background: Air fresheners are products with fragrances used to mask unpleasant odor in the environment. However, air fresheners contain diverse chemical substances that pose health challenges to the users; hence are of public health significance. Although previous studies have shown that air fresheners affect the lungs, liver and reproductive organs, the neurobehavioral effects of these agent...
