Exposure to multiple chemicals may cause significant alterations of tissue dose of the toxic moiety of one or more of the individual chemicals. The change in target tissue dose of a chemical present in simple mixtures can be predicted when the determinants of disposition of each chemical, and the mechanism of toxicokinetic interaction between chemicals are understood at a quantitative level. De...
Evaluation of a larger number of chemicals in commerce from the perspective of potential human health risk has become a focus of attention in North America and Europe. Screening-level chemical risk assessment evaluations consider both exposure and hazard. Exposures are increasingly being evaluated through biomonitoring studies in humans. Interpreting human biomonitoring results requires compari...
Background and aims Occupational diseases impose considerable burden on public health, wherein chemical pollutants in working places play an important role. One of chemical pollutants in vehicle's lock & key assembly factories is cyanoacrylate used in" loctite glue", which is assumed harmful to workers' eyes, respiratory tract and skin. This study investigates the side effects of loctite a...
Since the rose water is used in food, pharmaceutical, and cosmetic products, its microbiological control is necessary. Conventional pasteurization methods cause undesirable changes in taste, smell, medicinal properties and nutritional value with decreasing the amount of essential oil, because of high temperatures. In this study, the effects of the microwave power, temperature, ultrasound power,...

بررسی اثر سولفورموستارد بر وضعیت متیلاسیون پروموتر ژن FOXP3 در جانبازان شیمیایی با عوارض تأخیری ریوی
Background and Objective: Sulfur mustard (SM) is a toxic and chemical agent. The incidence of pulmonary complications and inflammatory processes play an important role in SM-exposed individuals. FOXP3 is one of the important factors in the development of chronic pulmonary diseases. FOXP3 gene promoter due to exposure to chemical and toxic materials leads to chronic pulmonary disease. In this st...
Iraq has used extensively chemical warfare agents in recent Iran-Iraq conflict (1980-1988) and it is believed about 450,000 people were exposed to this agents. Long-term effects of chemical warfare agents, particularly mustard gas, on pulmonary function tests (PFT) (VC, FEV1 , FVC, FEV/FVC, PEF, MEF50%, MEF25%, MEF25-75% , ERC and IC) are estimated during 7.7 [standard deviation (SD)=l.2] years...
