  1. 21. Environmental, nutritional and endocrine regulation of metabolic processes in fish

    Författare :Andreas Kullgren; Göteborgs universitet; []
    Nyckelord :lipids; metabolism; temperature; fasting; growth hormone; ghrelin; NMR; metabolomics; Salmo salar; Oncorhynchus mykiss;

    Sammanfattning : Due to seasonal variations in temperature and food availability, fish in temperate regions should be able to make metabolic adjustments to ensure that enough energy is available for the maintenance of basal processes. The major aim of this thesis was to elucidate how the physiology and lipid metabolism of salmonid fish is affected by temperature and food availability, and to clarify aspects of the endocrine control of lipid metabolism.

  2. 22. Dietary, Pharmacological and Environmental Effects on Brown Adipose Tissue

    Författare :Erik Lindsund; Tore Bengtsson; Jan Nedergaard; Karsten Kristiansen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Obesity; brown adipose tissue; uncoupling protein 1; moderate cold exposure; calorimetry; thyroxine; dietary protein; thermic effect of food; diet-induced thermogenesis; adrenergic stimulation; mice; physiology; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Obesity is a common health issue; over 12 % of the adult world population have obesity. Obesity has many co-morbidities including cardo-vascular diseases and diabetes. Obesity is the result of chronic positive energy balance, eating too much and expending too little. LÄS MER

  3. 23. Fuel and fly: adaptations to endurance exercise in migrating birds

    Författare :Anders Kvist; Bröstcancer-genetik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water balance; flight power; phenotypic flexibility; energy assimilation; basal metabolism; Animal ecology; Djurekologi;

    Sammanfattning : Birds on migration alternate between consuming fuel stores during flights and accumulating fuel stores during stopovers. This thesis highlights some of the ways in which migrating birds have adapted to the different demands of fuelling and flight. Most of the time on migration is spent at stopover sites accumulating fuel stores. LÄS MER

  4. 24. Functional Profiling Of Metabolic Regulation In Marine Bacteria

    Författare :Saraladevi Muthusamy; Jarone Pinhassi; Torsten Thomas; Sarala Devi Muthusamy; Institutionen för biologi och miljö (BOM) Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine microbiology; physiology; heterotrophic bacteria; adaptive strategies; survival; proteomics; growth phase; proteorhodopsin; inorganic sulphur oxidation; anaplerotic CO2 fixation; Miljövetenskap; Environmental Science;

    Sammanfattning : Oceans are powered by active, metabolically diverse microorganisms, which are important in regulating biogeochemical cycles on Earth. Most of the ocean surface is often limited by nutrients, influencing bacterial growth and activities. LÄS MER

  5. 25. The effect of various dietary fatty acids on adaptive thermogenesis

    Författare :Gabriella von Essen; Jan Nedergaard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysiologi; Physiology;

    Sammanfattning : Recently it has been revealed that brown adipose tissue (BAT) is present in adult humans and not, as thought before, only in infants and rodents. BAT, with a main function to generate heat, is also involved in energy metabolism by an adaptive response to eating, referred to as diet-induced thermogenesis (DIT). LÄS MER
