    Författare :Jóhanna Gunnarsdóttir; Anna-Karin Wikström; Sven Cnattingius; Ulf Högberg; Alexander Smárason; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Placental dysfunction; blood pressure; small-for-gestational-age; fetal growth restriction; intrauterine; prenatal exposure; postnatal height gain; linear growth;

    Sammanfattning : Preeclampsia is a placental-related disorder characterized by generalized endothelial activation. Vascular predisposition is associated with the occurrence of preeclampsia and the recurrence risk is substantial. LÄS MER

  3. 2. Reproductive function in young Swedish men - Time trend, prenatal and adult exposure to smoking and phthalates

    Författare :Jonatan Axelsson; Malmö Reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Semen analysis; maternal exposure; paternal exposure; smoking; phthalate;

    Sammanfattning : A decrease in male reproductive function, including sperm counts, during the second half of the 20th century, has been postulated. During this period, testicular cancer has increased several-fold. Environmental and lifestyle-related factors have been proposed as explanations for a possible negative trend in male reproductive function. LÄS MER

  4. 3. Assessment of Environmental Pollutants in Humans from Four Continents : Exposure levels in Slovakia, Guinea-Bissau, Nicaragua and Bangladesh

    Sammanfattning : Humans are continuously exposed to complex mixtures of anthropogenic chemicals. This thesis focus on human exposure to persistent organic pollutants (POPs). POPs ability to bioaccumulate and biomagnify together with the extensive historical use of POPs in e.g. LÄS MER

  5. 4. Maternal programming: costs, benefits and constraints of maternal hormone transfer

    Författare :Michael Tobler; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; aves; immune function; behavior; Maternal effects; hormones;

    Sammanfattning : Avian mothers convey significant quantities of androgens (i.e. ?male? steroids) to their eggs, which are known to positively influence embryonic development, post-natal growth and competitive behaviour of the offspring. However, there is large inter-female variation in the amount of androgens transferred to the eggs. LÄS MER

  7. 5. Exposure to perfluorinated alkyl substances and health effects in pregnant women and their children

    Författare :Matilda Ebel; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perfluorinated alkyl substances; epidemiology; prenatal exposure; maternal health; child health; register studies;

    Sammanfattning : Per- and polyfluorinated alkyl substances (PFAS) are chemicals that have gained attention during the last years. There are about 10,000 different PFAS compounds, and due to their unique chemical characteristics, PFAS has been used in a variety of industrial applications and household products since the 1950s.
