Personal protective equipment (PPE) is an important part of worker protection during filovirus outbreaks. The need to protect against a highly virulent fluid-borne pathogen in the tropical environment imposes a heat stress on the wearer that is itself a safety risk. No evidence supports the choice of PPE employed in recent outbreaks, and standard testing procedures employed by the protective ga...

BACKGROUND Little is known about the extent of human isocyanate skin exposure in auto body shops and the effectiveness of personal protective equipment. Animal studies have suggested that skin exposure to isocyanates may be an important risk factor for respiratory sensitization leading to asthma. This study provides initial data on hexamethylene diisocyanate skin exposure in three auto body sho...

background: synthetic radio-protective agents like aminothiols are toxic and fda approved agent amifostine is no exception. some ayurvedic herbs have shown radioprotective potential. this study was carried out to test and compare the radioprotective potential of curcuma longa (cl) tinospora cordifolia (tc), zizyphus mauritiana (zm) and ocimum sanctum (os) against 2gy gamma irradiation in swiss ...

long exposure of uv radiation increases risk of skin diseases such as cancer and photoallergic reactions. uv-b (280-320 nm) radiation is mainly responsible for inducing skin problems. skin protection is a suitable method in the fight against ultraviolet radiation induced damage. various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...

the present study investigated the radioprotective efficacy of lentil ( lens culinaris ) sprouts against x-ray radiation-induced cellular damage. lentil seeds were dark germinated at low temperature and the sprout extract was prepared in pbs. free radical scavenging of extract was evaluated using 2,2-diphenyl-1-picrylhydrazyl (dpph) assay and then the radioprotective potency of extract (0 to 10...

Aminothiols such as WR-2721 and its active free thiol WR-1065 have previously been shown to reduce mutations resulting from ionizing radiation in exponentially growing cells. In this study, non-dividing human G0 T-lymphocytes were exposed to the aminothiol radioprotective agent, WR-1065, 30 min before or 3 h after external beam gamma-irradiation and subsequently assessed for survival and mutati...

background: glioma is the most common primary brain tumor with poor prognosis. temozolomide (tmz) has been used with irradiation (ir) to treat gliomas. the aim of the present study was to evaluate the cytotoxic and radiosensitizing effect of tmz when combined with high-dose and high-dose rate of gamma irradiation in vitro. methods: two ‘u87mg’ cell lines and skin fibroblast were cultured and as...

Singleand double-stranded (RF) DNA of page <?X-174 were 60Co-gamma irradiated. Depen­ dence of radiosensitivity on the concentration of cysteamine and cystamine was measured. Radio­ resistance of DNA in vivo (phage particles) as well as of DNA in vitro (infectious DNA) increase between 10-4 and 10—1 M of superprotective agents. The same relationship is observed when the DNA is in the dry and in...
