  5. 19. Gene-environment interactions for arsenic metabolism and metal-related oxidatively generated DNA damage

    Författare :Karin Engström; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AS3MT; methylation; polymorphism; 8-oxodG;

    Sammanfattning : Over 100 million people around the world are exposed to high concentrations of arsenic (As) in drinking water, associated with a number of adverse health effects such as skin, lung and bladder cancer, vascular diseases and diabetes. In humans, As is metabolized via alternating reduction and methylation reactions, from inorganic As (iAs) into monomethylated (MMA) and dimethylated As (DMA). LÄS MER

  7. 20. Daphnids adaptive strategies to UV radiation

    Författare :Carla Eloisa Fernández; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :Cladocera; Zooplankton; Andean lakes; Daphnia; Ultraviolet radiation; Migration strategy; Photo-protection;

    Sammanfattning : This thesis focuses on the adaptive strategies of daphnids that allows them to maintain stable populations while deal with UV radiation, highlighting the differences in the responses that populations with different evolutionary histories may have.Although exposition to lethal doses in nature is unlikely, sub-lethal UV-B radiation doses may have strong impacts on zooplankton.
