  1. 1. Uptake, turnover and distribution of chlorinated fatty acids in aquatic biota

    Författare :Helena Björn; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; porpoise; fish; metabolism; food chain; respiration; membrane; phospholipid; chlorohydrins; lipid; Ecology; Ekologi;

    Sammanfattning : Chlorinated fatty acids (ClFAs) are the major contributors of extractable, organically bound chlorine in fish lipids. A known anthropogenic source of ClFAs is chlorine bleached pulp production. Additional anthropogenic sources may exist, e.g. LÄS MER

  3. 2. Effects of feeding yeasts on blood physiology and gut microbiota of rainbow trout

    Författare :David Huyben; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Yeast represents a sustainable protein alternative to fishmeal in diets for farmed fish, although more than 40% replacement has been shown to reduce fish growth and welfare. This thesis investigated the effects of feeding high inclusions of inactivated and live yeasts to fish in order to replace fishmeal without negative health consequences. LÄS MER

  4. 3. Metabolomics as a tool to evaluate salmonid response to alternative feed ingredients

    Författare :Ken Cheng; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Aquaculture has largely expanded in the last decades to satisfy the growing market demands for fish products. Fishmeal and fish oil, which are traditionally used in salmonid feeds, are becoming unsustainable. Development of aquafeeds based on alternative ingredients are needed to overcome the ecological challenges. LÄS MER

  5. 4. Metabolic consequences of a Paleolithic diet in obese postmenopausal women

    Författare :Caroline Blomquist; Tommy Olsson; Elin Chorell; Per-Arne Svensson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postmenopausal women; Paleolithic diet; randomized diet intervention; fat metabolism; low-grade inflammation; circulating fatty acids; diet validation; obesity; insulin resistance; Postmenopausala kvinnor; Paleolitisk kost; randomiserad kostintervention; fettmetabolism; fetma; låggradig inflammation; cirkulerande fettsyror; kostvalidering; fetma; insulin resistens; medicin; Medicine;

    Sammanfattning : BackgroundObesity, in particular abdominal adiposity, is associated with elevated fatty acids and pro-inflammatory adipokines, which are linked to ectopic fat storage and insulin resistance. During menopause, there is a redistribution of fat from the peripheral to abdominal depots. LÄS MER

  7. 5. ALPHA-LINOLENIC ACID Postprandial Lipid Metabolism and Enzymatic Interesterification of Triacylgylcerols

    Författare :Julia Svensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alpha-linolenic acid; triacylglycerol; postprandial lipemia; Lipozyme TL IM; interesterification;

    Sammanfattning : An important indicator of the metabolic capacity of humans is the ability to regulate plasma triacylglycerol levels and to clear triacylglycerol-rich lipoproteins (TRLs) from the circulation after a meal. This is crucial since most of the day is spent in the postprandial state. LÄS MER
