  1. 6. Exposure and effects of naturally produced hydroxylated polybrominated diphenyl ethers in fish : Implications for Baltic Sea wildlife

    Författare :Johan Gustafsson; Lillemor Asplund; Pim E.G. Leonards; Marja H. Lamoree; Robert Letcher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecotoxicology; Metabolomics; OH-PBDE; Algae; Cyanobacteria; Natural products; Thiamine; Health; Biomarker; Seasonal variation; Perch; Zebrafish; Flame retardant; Mixture; 6-OH-BDE47; Energy metabolism; Endocrine disruption; Neurotoxicity; OXPHOS; Environmental Chemistry; miljökemi;

    Sammanfattning : The aim of this thesis was to investigate if naturally produced hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are causing negative health effects for Baltic Sea wildlife. In the laboratory, OH-PBDEs have shown to be potent disrupters of energy metabolism as well as endocrine disruptors and neurotoxins. LÄS MER

  3. 7. Thiamin (vitamin B1) in the aquatic food web

    Författare :Emil Fridolfsson; Samuel Hylander; Michael T. Brett; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; zooplankton; thiamin; transfer; food web dynamics; micronutrient; vitamin; Baltic Sea; community composition; M74; salmon; B1; växtplankton; djurplankton; tiamin; överföring; födoväv; mikronäringsämne; vitamin; Östersjön; B1; lax; Ecology; Ekologi;

    Sammanfattning : Thiamin (vitamin B1) is required for several life-sustaining processes in most organisms and cells, e.g. in the conversion of food to energy. It also serves as an antioxidant and is important for proper nerve signaling. LÄS MER

  4. 8. Airway antioxidant responses to oxidative air pollution and vitamin supplementation

    Författare :Annelie Behndig; Anders Blomberg; Ian S Mudway; Ragnberth Helleday; Isabelle Romieu; Umeå universitet; []
    Nyckelord :Medicine; air pollution; ozone; diesel exhaust; airway inflammation; antioxidant; vitamin C; dehydroascorbate; vitamin supplementation; Medicin; lungmedicin; Lung Medicine;

    Sammanfattning : Air pollutants, such as ozone (O3) and diesel exhaust particles, elicit oxidative stress in the lung. Antioxidants within the respiratory tract lining fluid (RTLF) protect the underlying tissue from oxidative injury. LÄS MER

  5. 9. Congenital malformations in experimental diabetic pregnancy : Aetiology and antioxidative treatment

    Författare :Martin Simán; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pregnancy; teratology; malformations; embryo; fetus; cataract; sorbitol; antioxidants; butylated hydroxytoluene; vitamin E; vitamin C; TBARS; neural crest cells; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Diabetes mellitus in pregnancy causes congenital malformations in the offspring.The aim of this work was to characterize biochemical and morphologic anomaliesin the conceptus of an animal model of diabetic pregnancy. In addition, apreventive treatment against diabetes-induced dysmorphogenesis was developed. LÄS MER

  7. 10. Experimental and Clinical Studies of Oxidative Stress in Pre-Eclampsia

    Författare :Peppi Nash; Ulf Eriksson; Matts Olovsson; Leif Jansson; Lucilla Poston; Uppsala universitet; []
    Nyckelord :Obstetrics and gynaecology; Pre-eclampsia; Oxidative stress; Diabetes; Placenta; Rat; Antioxidants; Suramin; Vitamin E; Vitamin C; PAI-1; PAI-2; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Impaired placentation and oxidative stress are proposed to play major roles in the pathogenesis of pre-eclampsia (PE). It has recently been pointed out that PE might be more than one disease and may have several different pathogeneses. LÄS MER
