  1. 1. Fat metabolism : A clinical and experimental study with special reference to newborns

    Författare :Gertrud Angsten; Karl-Anders Dahlström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; neonates; total parenteral nutrition; plasma and muscle carnitine; carnitine reference intervals; medium-chain triglycerides; Kirurgi; Surgery; Kirurgi; kirurgi; särskilt barnkirurgi; Pediatric Surgery;

    Sammanfattning : Lipid emulsion is an important constituent of total parenteral nutrition (TPN). In the investigations described in this thesis the effects of different lipid emulsions in neonates were studied. LÄS MER

  2. 2. Nutrition in the second year of life. Effects of different milk compositions on dietary intakes, growth and metabolism

    Författare :Johan Svahn; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein intake; nitrogen; iron fortification; iron intake; growth; fatty acids; fat metabolism; fat intake; energy intake; dietary intake; blood lipids; cow´s milk; cholesterol; Amino acids; children; protein metabolism.; Pediatrics; Pediatri;

    Sammanfattning : In the diet for young children, whole cow´s milk is the major contributor of calories, protein and saturated fat, but it supplies little iron and polyunsaturated fat. Although several recommendations exist for the composition of formula, recommendations for the composition of milk for young children are lacking. LÄS MER

  3. 3. Dietary Fatty Acids, Body Composition and Ectopic Fat : Results from Overfeeding Studies in Humans

    Författare :Fredrik Rosqvist; Ulf Risérus; Tommy Cederholm; Ian Macdonald; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Linoleic acid; Palmitic acid; SFA; PUFA; Fatty acids; Body composition; Liver fat; Ectopic fat; Adipose tissue; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The aim of this thesis was to investigate the effects of dietary fatty acids on body composition and ectopic fat in humans, with emphasis on the role of the omega-6 polyunsaturated fatty acid (PUFA) linoleic acid (18:2n-6) and the saturated fatty acid (SFA) palmitic acid (16:0). The overall hypothesis was that linoleic acid would be beneficial compared with palmitic acid during overfeeding, as previously indicated in animals. LÄS MER

  4. 4. Fatty Acid Desaturase Activities in Metabolic Syndrome and Cardiovascular Disease : Special Reference to Stearoyl-CoA-Desaturase and Biomarkers of Dietary Fat

    Författare :Eva Warensjö; Ulf Risérus; Bengt Vessby; Tommy Cederholm; David Laaksonen; Uppsala universitet; []
    Nyckelord :Nutrition; Fatty acids; Dietary fat; Biomarker; Metabolic Syndrome; Mortality; Obesity; Insulin Sensitivity; Epidemiology; Estimated desaturase activities; Stearoyl-CoA-desaturase; delta-6-desaturase; delta-5-desaturase; Single Nucleotide Polymorphism; Dietary Intervention; Rapeseed oil; Saturated fat; SCD1; Näringslära;

    Sammanfattning : The development of the metabolic syndrome (MetS) and cardiovascular diseases have been suggested to be influenced more by the quality than the amount of dietary fat. The FA composition of serum lipids may be used as biomarkers of dietary fat quality. LÄS MER

  5. 5. Sources of Arachidonic Acid in Platelets, Bone, Marrow and Gastrointestinal Tract

    Författare :Li Zhou; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phospholipids; Megakaryocyte; Lysophosphatidylcholine; Lipoproteins; Linoleic acid; Intralipid; Interconversion; Gastrointestinal tract; Plasma free fatty acids; Fasting; Dietary fatty acids; Desaturase; Cholesterol; Chylomicron remnant; Chylomicron; Arachidonic acid; Bone marrow; Platelets; Protein S; Prothrombin; Triglycerides.; Biochemistry; Metabolism; Biokemi; metabolism;

    Sammanfattning : This study investigates pathways by which the eicosanoid precursor pools in the platelets, bone marrow and the gastrointestinal (GI) mucosa are acquired and regulated, and in this context some aspects on the interaction between triglyceride (TG)-rich lipoproteins and platelets. 1.
