  4. 18. Mitochondrial function in human skeletal muscle: with special reference to exercise and training

    Författare :Michail Tonkonogi; Högskolan Dalarna; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :aerobic metabolism; oxidative phosphorylation; mitochondria; oxygen utilisation; citrate synthase; ADP sensitivity; ATP; muscle fibres; hydrogen ions; lactate; free radicals; proton leak; uncoupling; exercise; aerobic metabolism; oxidative phosphorylation; mitochondria; oxygen utilisation; citrate synthase; ADP sensitivity; ATP; muscle fibres; hydrogen ions; lactate; free radicals; proton leak; uncoupling; exercise;

    Sammanfattning : The overall objective of this thesis was to study the adaptation of oxidative function in human skeletal muscle to acute exercise of different modes, intensities and durations, and to endurance training. The effects of endurance training on mitochondrial function were evaluated in cross-sectional and longitudinal studies by measurements of mitochondrial oxygen consumption in isolated mitochondria and permeabilised muscle fibres and measurements of mitochondrial ATP production rate in isolated mitochondria.

  5. 19. Mechanisms of alloxan diabetogenicity

    Författare :Kjell Grankvist; Inge-Bert Täljedal; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alloxan; catalase; experimental diabetes; free radicals; islets of Langerhans; rubidium accumulation; superoxide dismutase; Trypan Blue;

    Sammanfattning : Suspensions of pancreatic islet cells from ob/ob-mice were incubated with Trypan Blue. Microscope photometry showed that apparently viable cells excluded the dye completely, whereas the nuclei of non-viable cells accumulated Trypan Blue by a saturable process. LÄS MER

  7. 20. Quantum chemical calculations of electron paramagnetic resonance of biological radicals

    Författare :Maria Engström; Shashi Karna; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The aim of this thesis was to use state-of-the-art quantum chemical calculations of electron paramagnetic resonance (EPR) with applications to radicals in biomolecular systems. Special emphasis has been devoted to investigations of structure-to-property relations of amino acid radicals and spin labels in proteins. LÄS MER
