  1. 16. Hepatitis C virus. Aspects on natural history, antibody response, and viral quantification

    Författare :Martin Lagging; Göteborgs universitet; []
    Nyckelord :Hepatitis C virus; nosocomial infection; pseudotyped virus; fibrosis; viral quantification;

    Sammanfattning : Hepatitis C virus (HCV) is the major cause of parenterally transmitted non-A, non-B hepatitis, and is associated with chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Despite the screening of blood products nosocomial spread of HCV continues to occur. LÄS MER

  3. 17. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    Författare :Malin Mejàre; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Sammanfattning : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. LÄS MER

  4. 18. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases

    Författare :Fredrik Johansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; morphology; taxonomy; Systematic botany; plant mitochondria; NAD P H dehydrogenases; cold treatment; complex I; light dependence; antimycin a; alamethicin;

    Sammanfattning : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. LÄS MER

  5. 19. Quantification and optimisation of lung ventilation SPECT images

    Författare :Pernilla Norberg; Michael Sandborg; Gudrun Alm Carlsson; Agneta Gustafsson; Katarina Sjögreen Gleisner; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Currently, lung function tests are the gold standard for lung function measurements. Since the outcome of a lung function test is a summation of the status of the whole lung, significant changes in lung function may occur before a deviation from the norm can be identified. LÄS MER

  7. 20. Seasonal variations in general activity, behaviour and cutaneous glandular structures in reindeer (Rangifer tarandus L.)

    Författare :Torgny Mossing; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Androgen; Cervidae; dermal glands; locomotor activity olfactory communicatiorL pheromones; photoperiod; rein deer; rut; seasonal variations;

    Sammanfattning : The locomotor activity of the reindeer is separated into a diurnal and a nocturnal phase which, in turn, consists of a  number of short-term activity bursts. The onset and termination  of diurnal and nocturnal activity are largely in synchrony  with sunrise and sunset. LÄS MER
