background: radioprotective effect of famotidine was previously shown on radiation induced micronuclei and chromosomal aberrations in human peripheral lymphocytes and mouse bone marrow cells however, its radioprotective property has never been studied in mouse spermatogenesis. it was also shown that vitamin c as an antioxidant also exert its radioprotective effect on many biological systems, bu...

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...

Exposure to radiation can damage endothelial cells in the irradiated area via the production of reactive oxygen species. We synthesized phosphine-borane complexes that reduce disulfide bonds and had previously been shown to interfere with redox-mediated signaling of cell death. We hypothesized that this class of drugs could interfere with the downstream effects of oxidative stress after irradia...

objective(s):cervical cancer is a malignancy that is the second most common cause of death from cancer in women throughout the world. paederus beetle (paederus fuscipes) extract (pbe), contains bioactive compounds such as pederine which has cytotoxic properties and blocks dna and protein synthesis at very low concentrations. in this investigation we tried to determine the effects co-treatment w...
