  2. 21. Analysis and human levels of persistent perfluorinated chemicals

    Author : Anna Kärrman; Gunilla Lindström; Bert van Bavel; Ulf Järnberg; Jessika Hagberg; Lennart Hardell; Derek Muir; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; SPE; LC-MS; human exposure; Chemistry; Kemi; Chemistry; Kemi;

    Abstract : An extensive use of perfluorinated chemicals (PFCs) in the last 50 years has resulted in a worldwide spread of these persistent chemicals. Human populations are subjected to a large number of PFCs in ways that are not yet fully explained. READ MORE

  4. 22. Perspectives on the Biological Role of Human Prostasomes

    Author : Lena Carlsson; Outi Hovatta; Uppsala universitet; []
    Keywords : Medical sciences; Prostasomes; cryopreservation; human spermatozoa; sperm motility; anti- prostasome antibodies; PC-3 cells; Bacillus megaterium; antibacterial; antisperm antibodies; complement activation; sperm agglutination; infertility; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Abstract : Prostasomes are extracellularly occurring organelles which are secreted in human semen by the prostate gland. Prostasomes have several known biological activities, but their physiological function is still unclear. In this thesis some new aspects were studied on the biological role of the prostasomes.

  5. 23. Human papillomaviruses in skin cancer and cervical cancer

    Author : Kristin Andersson; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human papillomavirus; serology co-factors; non-melanoma skin cancer;

    Abstract : The causal relationship between persistent genital infections with human papillomavirus (HPV) and development of cervical cancer is well established. In contrast, the significance of infections with cutaneous HPV for development of non-melanoma skin cancer (NMSC) is not well understood. READ MORE

    Abstract : Eosinophilic granulocytes are leukocytes that reside in the gastrointestinal and respiratory tracts. Their function in health is unknown. READ MORE

  7. 25. Human exposure to perfluoroalkyl acids

    Author : Robin Vestergren; Ian T. Cousins; Stuart Harrad; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkane sulfonic acids (PFSAs) are persistent organic contaminants which have been globally measured in human serum samples at low μg L-1 concentrations. One hypothesis, the so-called "indirect hypothesis", postulates that exposure to precursor compounds is responsible for the presence of PFCAs and PFSAs in human serum. READ MORE
