  3. 2. Molecular development of a thermostable β-glucosidase for modification of natural products

    Författare :Sami Khan; Bioteknik; []
    Nyckelord :Thermotoga neapolitana; TnBgl1A; Mutagenesis; Flavonoid; Quercetin; Immobilisation; Chaperones;

    Sammanfattning : The gene encoding a β-glucosidase originating from the extreme thermophile Thermotoga neopolitana has been cloned and expressed in Escherichia coli. The aim was to produce a thermostable enzyme that could be used to remove sugar residues from glucosylated natural products classified as flavonoids by applying a method combining extraction in hot pressurized water with enzymatic hydrolysis.

  7. 5. Aspects of physical activity in Rheumatoid Arthritis : associations with inflammation and cardiovascular risk factors

    Författare :Kristina Hörnberg; Solveig Wållberg Jonsson; Björn Sundström; Christina Helging Opava; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physiotherapy; rheumatoid arthritis; cardiovascular disease; aerobic capacity; physical activity; exercise; primary prevention;

    Sammanfattning : Background: Rheumatoid Arthritis (RA) is associated with an increased risk for cardiovascular disease (CVD), partially attributable to systemic inflammation and traditional risk factors for CVD. Since physical activity (PA) is strongly related to CVD in the general population, the aim of this thesis was to describe aspects of PA in patients with RA, and further to analyse associations with disease activity, traditional risk factors for CVD and subclinical atherosclerosis.
