Postradjatjon administration of vitamin C was evaluated for its possible effects on reducing Or reversing the effects of radiation. Stomach, duodenum, testes and bone marrow of male guinea pigs were examined for the effects of radiation e.g. degeneration, necrosis and cellularity. There was no significant difference in the effects of radiation between animals that received vitamin C and those t...

OBJECTIVES To explore the effects of computer radiation on weight and oxidant-antioxidant status of mice, and further to confirm that whether vitamin C has protective effects on computer radiation. METHODS Sixty Male adult ICR mice were randomly divided into six groups. each group give different treatment as follows: group A was control, group B given vitamin C intake, group C given 8 h/day c...

Radiation exposure with use of intraoperative fluoroscopy is a potential orthopedic occupational risk factor. The purpose of this study was to perform a prospective comparison of hand versus eye radiation exposure associated with mini-C-arm utilization and to test the hypothesis that routine mini-C-arm does not yield hand or eye dosages exceeding current recommended levels. Over a 12-month peri...

background: over the past few years, the rapid use of high frequency electromagnetic fields like mobile phones has raised global concerns about the negative health effects of its use. adaptive response is the ability of a cell or tissue to better resist stress damage by prior exposure to a lesser amount of stress. this study aimed to assess whether radiofrequency radiation can induce adaptive r...

background: the aim of the present study was to evaluate the radioprotective effect of grewia asiatica fruit pulp extract (gae) on swiss albino mice exposed to gamma radiation. in the present study radioprotective efficacy of grewia asiatica (rich in anthocyanin, carotenes, vitamin c, etc.) was studied against radiation induced biochemical alterations in mice cerebrum. materials and methods: fo...

Introduction: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that c...

monitoring the effective parameters of drying crops is necessary to evaluate and determine system performance under real conditions. hence, a monitoring system was constructed to determine the performance of a vegetation forced-convection solar dryer. digital temperature sensors were set up in the air inlet and outlet of the collector and the air outlet of the drying chamber. a program was writ...

Carum copticum L. is a medicinal plant of the Apiaceae family with medicinal properties. In this study, the effects of UV-B radiation on the photosynthetic pigments and essential oils as well as phenols and anthocyanin of the seedling and callus of C. copticum were investigated under in vitro conditions. For this purpose, the experiment was set up in a completely randomized design, with three r...

We examined the mechanisms by which two different types of photonic radiation, short wavelength UV (UV-C) and gamma radiation, activate transcription factor NF-kappaB. Exposure of mammalian cells to either form of radiation resulted in induction with similar kinetics of NF-kappaB DNA binding activity, nuclear translocation of its p65(RelA) subunit, and degradation of the major NF-kappaB inhibit...
