Radiation Hormesis in Humans Exposed to Low Level Ionizing Radiation
Through various researches and investigations it has been established that high doses of ionizing radiation are harmful to health. There is substantial controversy regarding the effects of low doses of ionizing radiation despite the large amount of work carried out (both laboratory and epidemiological). According to the linear no-threshold (LNT) hypothesis, any amount, however small, of radiati...
متن کاملRadiation in low doses reduces life span of Daphnia magna∗
The effects of low-dose -irradiation on the crustacean Daphnia magna have been analyzed. Given that the LD50 for this species is approximately 100Gy, one-day-old daphnids were exposed to 10, 100 and 1000mGy of acute -rays. The survival of irradiated animals was evaluated over the maximum lifespan of 90 days. Increased mortality among irradiated at doses of 100 and 1000mGy daphnids was found. Ou...
متن کاملSucralose Induces Biochemical Responses in Daphnia magna
The intense artificial sweetener sucralose has no bioconcentration properties, and no adverse acute toxic effects have been observed in standard ecotoxicity tests, suggesting negligible environmental risk. However, significant feeding and behavioural alterations have been reported in non-standard tests using aquatic crustaceans, indicating possible sublethal effects. We hypothesized that these ...
متن کاملReduced DNA damage in tumor spheroids compared to monolayer cultures exposed to ionizing radiation
Background: Several cell lines when cultured under proper condition can form three dimensional structures called multicellular tumor spheroids. Tumor spheroids are valuable in vitro models for studying physical and biological behavior of real tumors. A number of previous studies using a variety of techniques have shown no relationship between radiosensitivity and DNA strand breaks in monolayer ...
متن کاملDaphnia magna
The cellular architecture of the Daphnia compound eye visual system was studied by using computer-aided techniques. All the neurons in one half of the bilaterally symmetric optic ganglion (OG) were reconstructed in three dimensions from serial electron micrographs. The techniques employed were those developed by Levinthal and collaborators (Macagno, Levinthal, and Sobel, Ann. Rev. Biophys. Bioe...
