  1. 11. Nitric Oxide Synthase in Pancreatic Islets During Trauma and Parenteral Feeding

    Författare :Saleem Qader; Islet cell physiology; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Gastroenterologi; Gastro-enterology; Pancreatitis; Ghrelin; TPN; cNOS; iNOS; PACAP; VIP; cAMP; Pancreatic islets; Insulin secretion;

    Sammanfattning : The influence of trauma (acute pancreatitis) or total parenteral nutrition (TPN) on pancreatic islet hormone secretion in relation to islet expression of inducible nitric oxide synthase (iNOS) was investigated. Acute pancreatitis resulted in an impaired glucose-stimulated insulin secretion (GSIS) which was found to be parallelled by a marked expression of iNOS and an exaggerated NO production in the pancreatic islets.

  3. 12. Studies on the regulation and in vitro metabolic effects of leptin in children and adults

    Författare :Amira M I Elimam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Leptin; growth hormone; cortisol; Dexamethasone; insulin; fasting; total parenteral nutrition; meal timing; obese children; Prader Willi syndrome; adipocyte; lipolysis; lipogenesis.;

    Sammanfattning : Leptin is a protein hormone secreted by adipocytes, which binds to receptors in the brain to affect food intake and energy expenditure. The leptin receptor is a member of the cytokine receptor family and is widely distributed in the body suggesting a broader role for leptin. LÄS MER

  4. 13. Muscle protein synthesis : effects of metabolic stress and feeding

    Författare :Inga Tjäder; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Surgical trauma and critical illness are pathophysiological conditions where the metabolic stress leads to an imbalance between protein synthesis and protein breakdown, resulting in a net loss of body proteins. A major part of the protein losses comes from skeletal muscle. Muscle depletion is associated with a high morbidity and mortality. LÄS MER

  5. 14. Glutathione during stress in man

    Författare :Urban Fläring; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Glutathione, a tripeptide (gamma-glutamyl, -cysteinyl, -glycine), is quantitatively the most important antioxidant in man, protecting cells from the toxic effects of reactive oxygen species (ROS). These highly reactive molecules cause tissue damage and are produced at high rates during critical illness including sepsis [1-4]. LÄS MER

  7. 15. Influences of some exogenous factors on the gastrointestinal ecosystem

    Författare :Aina Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Intestinal ecosystem; Intestinal microflora; Germ-free life; MACs; Establishment; TPN; EN; Probiotics; Lactobacillus delbrueckii; Streptococcus thermophilus; Faecal enema;

    Sammanfattning : An intestinal ecosystem has three major actors, i.e., the macroorganism, the microflora and the environment. LÄS MER
