Background: Some operating room personnel are occupationally exposed to genotoxic agents such as anesthetic gases and ionizing radiation. Adaptive response, as a defense mechanism, will occur when cells become exposed to a low dose of factors harming DNA (priming dose), which in the subsequent exposure to higher dose of those factors (challenging dose), show more resistance and sensibility.. <b...
reducing production and death. The disease in endemic areas would be mild or subclinical in indigenous cattle and clinically acute in exotics. OBJECTIVES: This study was conducted to evaluate the resistance of indigenous cattle in comparison with Holstein and crossbred cattle against Theileria annulata through assessment of clinical signs and response to treatment. METHODS: For this purpose...
objective(s): nucleus raphe magnus (nrm) that is involved in the regulation of body temperature contains nitric oxide (no) synthase. considering the effect of no on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. materials and methods: to this end, tail blood flow of male wistar rats was measured by laser doppler following the induction of ...
Background: Aspergillus flavus is the most important fungus for production of Aflatoxin B1 (AFB1). This study evaluated the ability of gamma rays (GRs) and electron-beam irradiation (EBI) to counteract the deleterious effects of aflatoxin B1 (AFB1) in a chicken model. Methods: Overall, 168 one-day-old male Coturnix quails were assigned to eight treatments for 42 d in Tehran, Iran, in 2010 and ...
Estimation of absorbed dose for radiation workers or person involved in different radiological accident is the aim of biodosimetry. Cytogenetic methods are the most current and applicable biodosimetry tools. In chronic or protracted exposure, fluorescence in situ hybridization (FISH), stable chromosomal aberration is used for estimation of absorbed dose. For precise estimation of absorbed dose,...
