BACKGROUND There are inconsistencies about the effects of farmworker housing and workplace conditions and use of self-protective behavior practices and personal protective equipment (PPE). OBJECTIVE To investigate the association between workplace and housing conditions and farmworker use of pesticide safety practices and PPE. METHODS This study was conducted in 4 counties in North Carolina...

Several hypotheses have been advanced in attempts to account for the ability of certain thiol (SH)or disulfide (SS)-containing compounds to reduce the biological lesions caused by ionizing radiation (1, 2). It is clear that, in pure aqueous solutions, radiochemical transformations are for the greater part mediated by products formed by the interaction of ionizing radiation with water molecules ...

Unavoidable exposure to radiosensitive normal tissues around cancerous tumor during 9 the radiotherapy can cause side effects such as self-limited acute toxicities, mild chronic symptoms, 10 or severe organ dysfunction. Nevertheless, clinical use of currently available radiation protective 11 agents is limited because of their generic cytotoxicity. A study on radiation protective effect of 12 d...

BACKGROUND Radiation therapy plays an important role in lung carcinoma treatment. However, the incidence of symptomatic radiation-induced lung injury is high. This study aimed to evaluate radioprotective effects of flavonoids extracted from Astragalus complanatus and mechanisms of action against radiation damage. METHODS Alteration in antioxidant status and levles of several cytokines were in...

It is well known that most of the ionizing radiation-induced damage is caused by hydroxyl radicals (·OH) follows radiolysis of H2O. Molecular hydrogen (H2) has antioxidant activities by selectively reducing ·OH and peroxynitrite(ONOO-). We firstly hypothesized and demonstrated the radioprotective effect of H2 in vitro and in vivo, which was also repeated on different experimental animal models ...

It has been demonstrated that hydrogen can selectively reduce hydroxyl and peroxynitrite in vitro. Since most of the ionizing radiation-induced cellular damage is caused by hydroxyl radicals, this study was designed to test the hypothesis that hydrogen may be an effective radioprotective agent. This paper demonstrates that treating cells with hydrogen before irradiation could significantly inhi...

The purpose of this study was to determine radioprotective effects of troxerutin. Cell experiments were carried out to test the cytotoxicity of troxerutin on V79 cells and to observe effects on apoptosis caused by 60CO γ rays. A model of 8 Gy ray-caused damage of mice was established to observe the effect that troxerutin has on the physical symptom of irradiated mice and to calculate the 30-day...

T he handheld umbrella (HU) is a commonly employed method of sun protection by women in many countries in Asia (45% in China) and the Middle East. In Turkey, hats and umbrellas were found to be the most common photoprotection accessories. The HU was standard outdoor attire for women of the 18th and 19th centuries in the United States. In the next century, sunscreen, hats, and sun-protective clo...
