  1. 1. Deg/HtrA proteases of the cyanobacterium Synechocystis sp. PCC 6803 : from biochemical characterization to their physiological functions

    Författare :Xuân Tâm Lâm; Christiane Funk; Jörg Nickelsen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deg; HtrA; protease; chaperone; Synechocystis sp. PCC 6903; biochemical characterization; physiological function; proteomics; structure;

    Sammanfattning : The family of Deg/HtrA proteases is present in a wide range of organisms from bacteria, archaea to eukaryota. These ATP-independent serine endopeptidases play key roles in the cellular protein quality control. The cyanobacterium Synechocystis sp. LÄS MER

  3. 2. Physiological roles of amyloid precursor protein in vivo - zebrafish as a model

    Författare :Jasmine Chebli; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloid-beta precursor protein; amyloid precursor protein-b; zebrafish; physiological functions; development; trigeminal ganglia; ependyma; cilia; proteomics; translational adaptation;

    Sammanfattning : Amyloid-beta precursor protein (APP) is an evolutionarily conserved transmembrane protein expressed in many different tissues. APP belongs to a gene family consisting of two other APP-like proteins (APLP1 and APLP2). LÄS MER

  4. 3. Impact of food quality on aquatic consumers : Behavioral and physiological adjustments

    Författare :Alfred Burian; Winder Monika; Kevin Flynn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine Ecology; marin ekologi;

    Sammanfattning : Food quantity and quality together determine growth rates of consumers and the utilisation efficiencies of available resources in aquatic and terrestrial ecosystems. The effect of food quality on the performance of consumers is dependent on both, its direct influence on ingestion and assimilation rates, and on the behavioural and physiological adjustments of consumers to their food environment.

  5. 4. Biosynthesis and physiological functions of N-acyl amino acids

    Författare :Dominik Paweł Waluk; Mary C. Hunt; David Merkler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

    Sammanfattning : N-acyl amino acids are lipid signalling molecules that have recently been identified in biological systems. These lipids are structurally related to the endocannabinoids, although they do not activate cannabinoid receptors. LÄS MER

  7. 5. Luminal Hypotonicity and Duodenal Functions : An Experimental Study in the Rat

    Författare :Liselotte Pihl; Olof Nylander; Gunnar Flemström; Mats Jodal; Uppsala universitet; []
    Nyckelord :Physiology; luminal alkalinization; mucosal permeability; osmolality; cyclooxygenase-2; rat; duodenum; jejunum; motility; enteric nervous system; Fysiologi;

    Sammanfattning : After drinking water, the fluid quickly leaves the stomach thereby creating a hypotonic luminal environment in the duodenum. This in turn constitutes a potential threat to the integrity of the duodenal epithelium. It therefore seems highly likely that luminal hypotonicity activates physiological mechanisms that aim to increase luminal osmolality. LÄS MER
