  1. 1. Endogenous t-PA release and pharmacological thrombolysis - Experimental animal studies of the coronary circulation

    Författare :Jan-Arne Björkman; Göteborgs universitet; []
    Nyckelord :Klinisk fysiologi;

    Sammanfattning : Abstract The physiologically most important activator of intravascular fibrinolysis is tissue-type plasminogen activator (t-PA) released from endothelial cells. In man, sympathomimetic drugs increase the systemic concentration of t-PA. LÄS MER

  3. 2. Palladium-promoted synthesis of compounds labelled with ¹¹C : Synthesis of ¹¹C-labelled prostacyclin and prostaglandin analogues

    Författare :Margareta Björkman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Palladium-promoted reactions have been employed for the synthesis of compounds labelled with 11C (t½ = 20.3 min). The precursor [11C]methyl iodide was used in palladium-promoted cross-coupling reactions with organostannanes. LÄS MER

  4. 3. GB virus C/hepatitis G virus infection: clinical, histological and epidemiological aspects

    Författare :Per Björkman; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endoscopy; nosocomial; sexual transmission; parenteral transmission; blood donor; ALT; liver disease; hepatitis; GBV-C HGV; HCV; Infections; Infektioner;

    Sammanfattning : GBV-C/HGV is a blood-borne virus related to the hepatitis C virus. We studied GBV-C/HGV infection in different populations, its transmission, and its association with liver disease. GBV-C/HGV viraemia was detected by PCR in 19/576 blood donors. Donors with normal and elevated ALT levels had similar rates of viraemia (1. LÄS MER

  5. 4. Molecular mechanisms of antibody diversification in human B-cells

    Författare :Andrea Björkman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : B-cells undergo several somatic rearrangement/mutational processes during development to diversify their immunoglobulin (Ig) receptors. First, the antigen binding Ig variable (V) region is assembled through V(D)J recombination. LÄS MER

  7. 5. The Late Holocene history of beech Fagus sylvatica and Norway spruce Picea abies at stand-scale in southern Sweden

    Författare :Leif Björkman; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; south Sweden; Late Holocene; succession; disturbance; forest history; forest continuity; population dynamics; immigration; palaeoecology; pollen analysis; Fagus sylvatica; Picea abies; Geologi; fysisk geografi; Palaeobotany; phylogeny; palynology; Paleobotanik; fylogeni; palynologi;

    Sammanfattning : High resolution pollen analysis was carried out on five peat profiles from small forest hollows at four sites in southern Sweden. The general aim was to investigate the establishment of Fagus sylvatica and Picea abies at stand-scale. LÄS MER
