  1. 1. Leptin endocrinology and energy homeostasis in salmonids

    Författare :Marcus Johansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Leptin; Leptin binding-protein; Energy homeostasis; Oncorhynchus mykiss; Salvelinus alpinus; Adiposity; Food intake; Fasting; Refeeding; Catabolism; Anorexia;

    Sammanfattning : In salmonids, the physiological role of leptin is not completely elucidated. Nonetheless, the anorexigenic effect of leptin indicates a role in their energy homeostasis. This thesis focuses on advancing the understanding of the involvement of the leptin system in the regulation of energy homeo-stasis and food intake in teleost fish. LÄS MER

  3. 2. Weight loss studies in obese patients. Aspects of very-low-energy diet treatment and effects of obesity surgery on disability pension

    Författare :Lena Gripeteg; Göteborgs universitet; []
    Nyckelord :obesity; weight loss; outcome; predictive factors; controlled trial; randomised trial; obesity surgery; very-low-energy diet; disability pension; eating behaviour; quality of life;

    Sammanfattning : Obesity is associated with increased risk of serious medical conditions, impaired quality of life, reduced working capacity, and shortened life expectancy. Obesity surgery is the most effective weight loss treatment with large health benefits, including reduced mortality. However, the long-term effects on productivity loss are not known. LÄS MER

  4. 3. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction

    Författare :Emmanouil Tsakoumis; Monika Schmitz; Tatjana Haitina; Åsa Wallén-Mackenzie; Ana Gómez Peris; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zebrafish; leptin; appetite; GRN; brain; reproduction; oocyte maturation; ovulation; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Sammanfattning : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. LÄS MER

  5. 4. Regulation of Elovl and fatty acid metabolism

    Författare :Annelie Brolinson; Anders Jacobsson; Jaap Keijer; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fatty acid metabolism; fatty acid elongation; Physiology; Fysiologi; Physiology; fysiologi;

    Sammanfattning : Fatty acids are important regulators in the control of mammalian energy homeostasis. They are ingested in the diet but a significant amount are also endogenously produced by de novo lipogenesis. LÄS MER

  7. 5. Chromatin transcription and dietary proteins : with observations on the RNA synthesis of rat liver in response to the protein content and amino acid composition in the diet

    Författare :Stefan U. Åström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis aims at characterization of fractionated chromatin with respect to bound and free RNA polymerase activities together with an analysis of the in vitro transcription of chromatin after changing the protein or amino acid content of the diet.Rat liver nuclei were incubated with micrococcal nuclease which acts as an endonuclease on DNA.
