  1. 1. Linking exposure pathways to internal concentrations of brominated flame retardants in Swedish mothers and their toddlers

    Författare :Leena Sahlström; Cynthia A. de Wit; Ulla Sellström; Urs Berger; Jochen Mueller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BFR; PBDE; HBCD; EBFR; human exposure; serum; feces; house dust; food; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Brominated flame retardants (BFRs) have been used in a variety of consumer products to enhance their fire safety. This has resulted in exposure of the environment, wildlife and humans causing risks of endocrine disruption. LÄS MER

  3. 2. Who ate whom? Paleoecology revealed through synchrotron microtomography of coprolites (fossil feces)

    Författare :Martin Qvarnström; Živilė Žigaitė; Grzegorz Niedźwiedzki; Per Ahlberg; Karen Chin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coprolites; paleoecology; synchrotron microtomography; taphonomy; Triassic; Biologi; Biology;

    Sammanfattning : Fossil droppings, known as coprolites, are being increasingly recognized as a valuable source of paleoecological information with special regard to diets, parasitism, and physiology of extinct taxa. Here, it is suggested that the excellent preservation and amount of inclusions in the coprolites (e.g. LÄS MER

  4. 3. Pharmacokinetics of mercury from dental amalgam

    Författare :Gunilla Sandborgh Englund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Human; dental amalgam; mercury; blood; plasma; urine; saliva; feces; pharmacokinetics; kidney; chelating agents.;

    Sammanfattning : The overall aim of the present work has been to obtain quantitative and qualitative data on mercury from dental amalgam in humans. The influence of amalgam removal on mercury levels in blood, plasma and urine has been studied in twelve volunteers. All amalgam fillings were removed during one dental session. LÄS MER

  5. 4. Fecal calprotectin in children with special reference to inflammatory bowel disease

    Författare :Ulrika Lorentzon Fagerberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Biological markers; calcium-binding proteins; Leukocyte L1 Antigen Complex; calprotectin; acute- phase proteins; serum amyloid A; C-reactive protein; ELISA; feces; blood; children; adolescent; colitis; inflammatory bowel disease; colonoscopy; reference values; diagnosis.;

    Sammanfattning : This thesis aims to study the clinical usefulness of fecal calprotectin as a noninvasive marker of colonic inflammation in children with suspected or confirmed chronic inflammatory bowel disease (IBD). Calprotectin, a calcium-binding protein predominantly expressed in neutrophils, is stable in feces for several days, and can be measured by an enzyme-linked immunosorbent assay. LÄS MER

  7. 5. Phosphorus to horses and cows

    Författare :Gunilla Ögren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : It is important from a nutritional perspective to meet the phosphorus (P) requirements of animals. From an environmental perspective however, it is important not to feed more P than necessary, because excessive P will mainly be excreted with feces, and the soluble P fraction is vulnerable to runoff losses and may contribute to eutrophication.
