  1. 16. Vacuum-assisted closure in cardiac surgery - clinical outcome and vascular effects

    Författare :Johan Sjögren; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Kardiovaskulära systemet; Cardiovascular system; Infektioner; Infections; endothelium; vascular; central hemodynamics; risk factors; long-term survival; mortality; wound closure; cardiac surgery; vacuum-assisted closure; poststernotomy mediastinitis; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : The aim of this research was to clinically and experimentally evaluate the use of vacuum-assisted closure in poststernotomy mediastinitis after cardiac surgery. Vacuum-assisted closure (VAC) is a new wound-healing therapy based on the application of a local negative pressure to the wound. LÄS MER

  3. 17. Allergen-induced airway reactions in the pig in vivo : inflammatory mediators as targets for asthma therapy

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

    Sammanfattning : A pig model for studies of allergen-induced airway reactions has previously been developed. These pigs are actively sensitized to Ascaris suum and challenged with this antigen in the airways under anesthesia. LÄS MER

  4. 18. Importance of MAPK and PKC in cerebrovascular endothelin receptor changes

    Författare :Marie Henriksson; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; farmakognosi; farmaci; toxikologi; toxicology; pharmacy; pharmacognosy; Pharmacological sciences; Kardiovaskulära systemet; Cardiovascular system; Fysiologi; Physiology; cerebral arteries; ischemia; receptors; endothelin; Farmakologi;

    Sammanfattning : Endothelin is a vasoactive peptide that exerts its effect through two receptors; the endothelin type A (ETA) and type B (ETB) receptor. The contractile ETA receptor is localized on smooth muscle cells in the vascular wall, while the ETB receptors are mainly situated on endothelial cells, mediating vasodilatation. LÄS MER

  5. 19. 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

  7. 20. Hydronephrosis in childhood : An experimental and clinical study

    Författare :Nils Wåhlin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Hydronephrosis; experimental ureteral obstruction; tubuloglomerular feedback; renal blood flow; vasoactivre substances; pressure flow measurement; Kirurgi; Surgery; Kirurgi; kirurgi; särskilt barnkirurgi; Pediatric Surgery;

    Sammanfattning : In this thesis the pathophysiology of hydronephrosis due to ureteropelvic junction (UPJ) obstruction was studied. The kidney adapts to obstruction by changes in renal blood flow (RBF) and glomerular filtration rate (GFR). LÄS MER
