  1. 1. Metabolism of xenobiotics, reactive oxygen species and acyl-CoA in the rat and porcine ovary : with special emphasis on distribution and hormonal regulation

    Författare :Malin Boström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; xenobiotics;

    Sammanfattning : .... LÄS MER

  3. 2. Mutagenesis induced by xenobiotics : factors of importance and modification, with special emphasis on glutathione and glutathione transferases

    Författare :Lennart Romert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; genetik;

    Sammanfattning : Genetic changes induced by chemical agents can result in cancer. Such tumor formation can be linked to activationof oncogenes, often through specific, definable mutagenic events, e.g., single base-pair mutation in specific codons. LÄS MER

  4. 3. Exposure to xenobiotic chemicals disrupts metabolism, rhythmicity and cell proliferation in Drosophila melanogaster

    Författare :Hao Cao; Helgi B. Schiöth; Michael J. Williams; Jan Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xenobiotics; metabolism; insulin signalling; circadian rhythm; carcinogen; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Sammanfattning : Most species are constantly exposed to xenobiotic chemicals through multiple routes. Among all categories of xenobiotics, phthalates and bisphenols are two of the most widely used plasticizers and can be found in polyvinyl chloride (PVC) materials, medical devices and even drinking water.

  5. 4. Xenobiotics-induced phosphorylations of MDM2

    Författare :Gerd Pääjärvi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of the present study was to characterize the Mdm2 and p53 responses induced by DNA damaging xenobiotics and how these responses can be modified by non-genotoxic xenobiotics. During control conditions cellular levels of p53 are low. The level is regulated by Mdm2 and Mdm2 and p53 forms an autoregulatory loop. LÄS MER

  7. 5. Accumulation and Composition of Gully Pot Sediments under Varying Anthropogenic Activities

    Författare :Haoyu Wei; Lian Lundy; Maria Viklander; David Butler; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catch basin; Stormwater; Sediment; Urban runoff; Xenobiotics; Gully pot maintenance; Emerging pollutant; VA-teknik; Urban Water Engineering;

    Sammanfattning : Gully pots (GPs) are an integral urban drainage component, contributing to conveying runoff from urban surfaces and reducing the load of solids and associated contaminants entering downstream piped systems and receiving waters. Over time, the silting-up of GPs impairs their hydraulic performance, increasing the risk of GP blockage-induced flood events and reducing solids retention performance. LÄS MER
