conclusions comprehensive protection programs with on-the-job training courses for staff members are strongly recommended, as well as, the provision of radiological shields and gonad shielding protocols in radiology departments to reduce the patient’s radiation dose during radiological examinations. materials and methods a retrospective, observational cross-sectional study on the application of...

background: whether exposure to common electromagnetic fields affects human health adversely has been a controversial issue. the main goal of this study was to assess the role of 900 mhz microwave radiations with different specific absorption rates (sars), emitted from some widely used cell phones, on the induction of adaptive response in male balb/c mice after receiving a lethal dose of gamma ...

AIM The aim of study was test efficacy of accelerated postoperative radiotherapy--concomitant boost in patients with advanced larynx cancer. METHODS AND MATERIALS The prospective study included 112 patients with advanced larynx cancer after radical surgical treatment. Patients had postoperative radiation therapy, conventional (C) or accelerated (CB). RESULTS The 3-year overall survival in C...

Radiation Effect, Chloroplast, 0 2 Evolution, Immobilization, Radiation Polymerization, Low Temperatures The effect of y-ray irradiation and immobilization by means of radiation polymerization on PS II activity ( 0 2 evolution) of isolated chloroplasts from spinach was investigated. Reduction of 0 2 evolution activity by irradiation was small at lower temperatures below — 24 °C, but the activit...

A review is presented on the enhancement of MMC (mitomycin C) efficiency by the vitamins C, E and b-carotene using E. coli bacteria (AB 1157) and leukemia cells (HL 60) as a model for experiments in vitro. New and previously published spectroscopic and kinetic data of transients obtained by pulse radiolysis of MMC and the above mentioned vitamins were also discussed. Based on all these results ...

Resistance to desiccation was utilized in the selection of highly radiation-resistant asporogenous bacteria from non-irradiated sources. A bacterial suspension in phosphate buffer was dried in a thin film at 25 degrees C and 33% relative humidity. Storage under these conditions for 15 days or more reduced the number of radiation-sensitive bacteria. Further selection for radiation-resistant bact...

BACKGROUND Radiation-Induced Lung Injury has 2 components: radiation pneumonitis and radiation fibrosis. The pulmonary fibrosis has no known efficient treatment. The purpose of this study was to study the relationship between the oxidant/antioxidant status and pulmonary fibrosis in rats having radiation induced pulmonary fibrosis and to study the antioxidant effects of pentoxifylline, vitamin E...
