background: several effects of volatile organic compounds (vocs) have been recognized such as toxic and carcinogenic human health effects. to evaluate cancer risk of benzenes air samples were taken, at an automobile manufacturing painters in tehran following inhalation exposure. methods: to perform this study, cross-sectional was done in 2016. sampling was carried out by active pump sampler usi...

Serum concentration of FSH, LH, testosterone, prolactin, ACTH, cortisol, TSH, T4, T3 and resin T3 uptake were measured in 146 men who were exposed to vesicants used by the Iraqi regime a few days t04 weeks prior to testing. Clinical and laboratory findings had confirmed the use of mustard gas. Mean serum concentrations of FSH, LH, TSH and prolactin were not significantly different from no...

In the present study,we examined the effects of exposure to radiofrequency(RF)with intermediate frequency (IF) range at 40 kHz on immune response using a stress-induced immune suppression method and on concentrations of serum corticosterone in mice. We used antibody-forming cell (AFC) assay to evaluate the effects of RF radiation at 40 kHz on immune response in mice. The number of plaques forme...

Introduction: Astrocytes have an important role in many neurodegenerative diseases. Active astrocytes release inflammatory factors such as NO and ILs. Shikonin, a naphthoquinone pigment of Lithospermum erythrorhizon roots has anti-inflammatory and antitumoral effects. The present study aims to investigate the anti-inflammatory and toxic effects of Shikonin on cultured astrocytes. Methods...

Pfaffia glomerata (Spreng.) Pedersen plantlets were grown under different cadmium (Cd) concentrations (0, 20, 40, 60 and 80 μM) in a hydroponic system during 7 d. Plant growth, micronutrient, chlorophyll and carotenoid concentrations, as well as δ-aminolevulinic acid dehydratase (ALA-D; E.C.4.2.1.24) and acid phosphatase (AP; E.C.3.1.3.2) activities were analysed. Cadmium concentration in both ...

background: welding can produce dangerous fumes containing various metals especially carcinogenic ones. occupational exposure to welding fumes is associated with lung cancer. therefore, welders in gas transmission pipelines are known as a high-risk group. this study was designed to determinate the amounts of metals cr, ni, and cd in breathing zone and urine of welders and to assess the possibil...

   Due to its ability in chemical oxidation of contaminants, iron nanoparticle is a material of choice to remove lead ions from aquatic solutions. In this study a reduction method in solution phase was applied to synthesize thenanoparticles. Afterwards, the size of the synthesized particles were confirmed by Scanning Electron Microscopy. It is worth noting that th...
