  1. 21. Hormonal mechanisms of menstrual disturbances, metabolic disorders and effects of oral contraceptives in female athletes

    Författare :Anette Rickenlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Female athletes; athletic amenorrhea; polycystic ovary syndrome; body composition; bone mineral density; endothelial function; physical performance; oral contraceptives;

    Sammanfattning : Background: During the last decades the number of women participating in sports has increased dramatically. Although exercise has beneficial health effects for most of these women, we now realize that strenuous exercise may also have serious medical consequences. Menstrual dysfunction is common among athletes and the exact mechanisms are not known. LÄS MER

  3. 22. Interindividual variation in drug metabolism with focus on polymorphic cytochrome P450 2C9

    Författare :Mia Sandberg Lundblad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cytochromes P450 (CYP) are enzymes, mainly catalysing the oxidation of xenobiotics, in order to facilitate their excretion from the body. CYP2C9 is a polymorphic enzyme, which is responsible for the metabolism of about 10 % of all known drugs, e. LÄS MER

  4. 23. Chemical exposures, biological monitoring and cancer risks in Swedish aluminium foundries and remelting plants

    Författare :Håkan Westberg; Hans Welinder; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In aluminium foundries and remelting plants, a wide range of chemical agents are formed and emitted, including some highly toxic organochlorine compounds. This thesis explores emissions and exposures, as well as worker risk of porphyria and cancer. LÄS MER

  5. 24. Studies of Single and Multiple Ionization Processes in Rare Gases and some Small Molecules

    Författare :Lage Hedin; Raimund Feifel; Dag Hanstorp; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics;

    Sammanfattning : In this thesis various aspects of photoionization are investigated with respect to both single and multiple electron emission from atoms and molecules. The studies include both valence and core levels and involve transitions which leave the atoms or molecules in various charge states. LÄS MER

  7. 25. Bioaccumulation and biological effects of organic contaminants in Icelandic coastal waters

    Författare :Halldóra Skarphéđinsdóttir; Åke Granmo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Miljögifter; Marine Ecotoxicology; marin ekotoxikologi;

    Sammanfattning : In this thesis, studies on organic contamination from both diffuse and point sources in Icelandic waters are presented. The aim was to investigate bioaccumulation and biological effects of the contaminants or biomarkers, and their applicability in environmental marine coastal monitoring, especially in areas with moderate or low levels of contamination such as Iceland.
