  1. 1. Pancreatic Islet Transplantation : Modifications of Islet Properties to Improve Graft Survival

    Författare :Sanja Cabric; Olle Korsgren; Bo Nilsson; Peetra Magnusson; Michael Breimer; Uppsala universitet; []
    Nyckelord :Medicine; Diabetes; islet transplantation; islets of Langerhans; coagulation activation; IBMIR; hirudin; heparin; growth factor; angiogenesis; Medicin;

    Sammanfattning : During the past decade clinical islet transplantation has become a viable strategy for curing type 1 diabetes. The limited supply of organs, together with the requirement for islets from multiple donors to achieve insulin independence, has greatly limited the application of this approach. LÄS MER

  3. 2. Biomaterials and Hemocompatibility

    Författare :Anna E. Engberg; Kristina Nilsson Ekdahl; Peter Zipfel; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complement; Coagulation; Whole blood; Biomaterials; Polymers and Hemocompatibility; Immunology; Immunologi; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Biomaterials are commonly used in the medical clinic today; however, artificial materials can activate the cascade systems in the blood (complement-, coagulation-, contact- and fibrinolytic systems) as well as the platelets to various degrees. When an artificial surface comes in contact with blood, plasma proteins will be adsorbed to the surface within seconds. LÄS MER

  4. 3. 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

  5. 4. The effect of thrombin inhibitors on coagulation activity and generation of activated protein C

    Författare :Rikard Linder; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The direct thrombin inhibitor inogatran was, in the TRIM trial (n=1209), compared with unfractionated heparin (UFH) concerning the effect on cardiovascular end-points in unstable coronary artery disease. The results in TRIM demonstrated a trend towards a benefit for UFH during the treatment phase, which was reduced after drug withdrawal. LÄS MER

  7. 5. Early assessment of efficacy and safety of novel anticoagulants as exemplified by direct thrombin inhibitors. Non-clinical pharmacodynamic studies in vitro and in vivo

    Författare :Margareta Elg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animals; antidote; bleeding; inhibition constant; inogatran; association rate constant; melagatran; thrombin inhibitor; thrombosis; fibrinolysis;

    Sammanfattning : The drawbacks of today's anticoagulants are parenteral use (heparins), a narrow interval between efficacy and bleeding, and the high variability of effect with a consequent need for frequent monitoring (coumarins). The aim of the current studies was to evaluate properties important for efficacy and safety of novel anticoagulants, as exemplified by direct thrombin inhibitors, with non-clinical methods. LÄS MER
