  1. 21. The importance of arginase for vascular dysfunction in patients with glucose and lipid abnormalities

    Författare :Oskar Kövamees; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: Endothelial dysfunction is one important mediator behind atherosclerosis. Maintained bioavailability of nitric oxide (NO) is critical to keep the fragile balance of endothelial function. Reduced NO arise from reduced production or increased elimination of NO. LÄS MER

  3. 22. Mechanisms of endothelial cell dysfunction in Wegener's granulomatosis

    Författare :Carolina Holmén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Wegener´s granulomatosis; vasculitis; anti-endothelial cell antibody; circulating endothelial cell; vascular adhesion protein 1; MHC class-I related chain A;

    Sammanfattning : Vasculitides are a heterogeneous group of disorders that share a common feature of blood vessel inflammation. A major cell type of the blood vessel affected is the endothelial cell (EC). LÄS MER

  4. 23. Angiotensin-converting enzyme in cardiovascular function and dysfunction

    Författare :Liza Ljungberg; Toste Länne; Karin Persson; Urban Alehagen; Thomas Kahan; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Angiotensin-converting enzyme (ACE) is a key enzyme in the renin-angiotensin system, converting angiotensin I to the vasoactive peptide angiotensin II, and degrading bradykinin. Angiotensin II is a multifunctional peptide, acting on a number of different tissues. LÄS MER

  5. 24. Cytomegalovirus infection in vascular diseases and transplant rejection

    Författare :Mensur Dzabic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human cytomegalovirus (HCMV) infects 60-100% of the adult population. It belongs to the Herpesviridae family and establishes latency within its host post primary infection. HCMV reactivation is dependent on inflammation and the virus has evolved numerous mechanisms to sustain an inflammatory process and thus prolong its replication period. LÄS MER

  7. 25. Vascular functions in infants, children and their mothers

    Författare :Helena Martin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The function of the microvascular system was studied during early postnatal circulatory adaptation and in early-onset neonatal sepsis. We also studied large and small artery functions in infants and schoolchildren of low birthweight, a risk factor related to later development of cardiovascular disease and hypertension. LÄS MER
