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

    Författare :Li Zhou; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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.

  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; 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. Molecular heterogeneity of prostate cancer bone metastasis

    Författare :Erik Bovinder Ylitalo; Pernilla Wikström; Anders Bergh; Maria Brattsand; Vessela Kristensen; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; CRPC; castration-resistant; androgen receptor; splice variant; abiraterone; cabazitaxel; ABCB1; cholesterol; Mdr1; P-gp; bone metastasis; immune response; metabolism; osteoblast; osteoclast; BMP; methylation;

    Sammanfattning : Castration-resistant prostate cancer (CRPC) develops after androgen deprivation therapy of advanced PC, often with metastatic growth in bone. Patients with metastatic CRPC have very poor prognosis. Growth of CRPC, in most but not all patients, seems to involve androgen receptor (AR) activity, despite castrate levels of serum testosterone.

  4. 4. Steroid-Metabolizing Cytochrome P450 (CYP) Enzymes in the Maintenance of Cholesterol and Sex Hormone Levels

    Författare :Hanna Pettersson; Maria Norlin; Kjell Wikvall; Paolo Parini; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP27A1; CYP7B1; cytochrome P450; estrogen receptor; androgen receptor; cholesterol; sex hormone; hydroxylation; steroid metabolism; regulation of steroid levels; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Sammanfattning : The enzymes CYP27A1 and CYP7B1 are widely expressed in various human tissues and perform catalytic reactions in cholesterol homeostasis and endocrine signaling. We have investigated the metabolism of a synthetic oxysterol. LÄS MER

  5. 5. Apolipoprotein A-I in glucose metabolism and amyloidosis

    Författare :Oktawia Nilsson; Medicinsk proteinvetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloidosis; Apolipoprotein A-I; beta cell; cardiovascular disease; cholesterol efflux; diabetes; glucose metabolism; glycation; high-density lipoprotein; insulin secretion;

    Sammanfattning : The role of Apolipoprotein A-I (ApoA-I), the main protein component of HDL, in cholesterol transport and metabolism is well known and has been studied for more than four decades. More recently, ApoA-I protein has been shown to also have a positive role in glucose control by both stimulation of glucose uptake by muscles and by increasing glucose-stimulated pancreatic insulin secretion.
