  1. 1. Matrix metalloproteinases and their inhibitors in ocular neovascularization

    Författare :Björn Steén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Angiogenesis; Neovascularization; Retina; Bruch membrane; Cornea; MMP; TIMP; VEGF; In situ hybridization.;

    Sammanfattning : Growth of pathological new vessels (angiogenesis) in the eye is a leading cause of severe vision-loss. Ocular angiogenesis is seen in the anterior part of the eye as in corneal neovascularization, or in the posterior part as in diabetic retinopathy, retinopathy of prematurity or age-related macular degeneration.

  2. 2. Avian antibodies applied in particle enhanced turbidimetric immunoassay : Developement of serum/plasma calprotectin immunoassay and its clinical performance as a marker for bacterial infections

    Författare :Tom Nilsen; Anders Larsson; Bjørn Steen Skålhegg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sepsis; avian antibodies; calprotectin antigen; particle enhanced turbidimetric immunoassay.; Clinical Chemistry; Klinisk kemi;

    Sammanfattning : Calprotectin is a cytosolic protein in the granulocytes, consisting of S100A8 and S100A9. On the site of inflammation, the neutrophils release the cytosol as an inflammatory response. The circulating calprotectin concentration increases and can therefore be used as marker for neutrophil activation and inflammation. LÄS MER

  3. 3. Structural and functional studies of factor V in health and disease

    Författare :Mårten Steen; Malmö Klinisk kemi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; APC resistance and hemophilia; thrombosis; factor VIII; coagulation; factor V;

    Sammanfattning : The homologous blood coagulation factors V (FV) and factor VIII (FVIII) are important at sites of vascular injury for the amplification of the clotting cascade. Activated FV (FVa) serves as a cofactor to the enzyme activated factor X (FXa) in the activation of prothrombin. This complex is called the prothrombinase complex. LÄS MER
