  1. 16. Regulation of energy balance in Caenorhabditis elegans 

    Författare :Ming Sheng; Simon Tuck; Lars Nilsson; Carina Holmberg-Still; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C.elegans; fat metabolism; S6 Kinase; FT-IR; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Sammanfattning : Obesity is a medical condition in which excess body fat has been accumulated. It is most commonly caused by imbalance between energy intake and energy expenditure (lack of physical activity and lower metabolic rate, etc.). LÄS MER

  3. 17. Studies on cysteine-rich peptides from Nemertea and Violaceae : Proteomic and transcriptomic discovery and characterization

    Författare :Erik Jacobsson; Ulf Göransson; Håkan S. Andersson; Robert Burman; Espen Hansen; Uppsala universitet; []

    Sammanfattning : The overall aims of the projects included in this thesis were to discover, synthesize and characterize disulphide-stabilized peptides from marine worms (Nemertea sp.) and plants (Viola sp.). LÄS MER

  4. 18. Membrane Fluidity Regulation: From C. elegans to mammalian cells

    Författare :Ranjan Devkota; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAQR-2; adiponectin receptors; IGLR-2; saturated fats; membrane fluidity; fatty acid desaturation; unsaturated fatty acid; membrane homeostasis;

    Sammanfattning : Biological membranes are primarily an assembly of lipids and proteins. Collectively, these constituents within a phospholipid bilayer determine the physical membrane properties such as fluidity, viscosity, thickness, packing and permeability. Maintenance of membrane properties within acceptable margins, i.e. LÄS MER

  5. 19. Inhibition of the mevalonate pathway in C. elegans: Consequences and implications

    Författare :Parmida Ranji; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mevalonate pathway; C. elegans; atfs-1; mitochondrial unfolded response UPR ;

    Sammanfattning : The mevalonate pathway in human is responsible for the synthesis of cholesterol and other important biomolecules such as coenzyme Q (a component of the electron transport chain in mitochondria), dolichols (important for N-linked glycosylation of proteins) and isoprenoids (important for the membrane association of small GTPases). This thesis concerns novel findings about the effect of statin on the mevalonate pathway using C. LÄS MER

  7. 20. On enchytraeids and naidids: Life history traits and responses to environmental stress

    Författare :Anna-Karin Augustsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; oligochaeta; terrestrial naididae; toxicity testing; asexual reproduction; sexual reproduction; drought; environmental stress; metal pollution; Ekologi; Animal ecology; Djurekologi;

    Sammanfattning : My thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. LÄS MER
