  1. 1. Experimental studies on thrombin inhibition in acute- and chronic models of vessel wall injury

    Författare :Fredrik Scherstén; Göteborgs universitet; []
    Nyckelord :animal model; antithrombin; fibrinogen; histomorphology; melagatran; percutaneous coronary intervention; platelets; restenosis; stent; thrombin inhibition; thrombosis;

    Sammanfattning : Background: The number of percutaneous coronary interventions (PCI) performed worldwide has increased dramatically during the last decade. Complication rates have decreased over time, however the restenosis phenomenon remains an unsolved issue. Thrombin is the key regulator in the pro-coagulant state following PCI. LÄS MER

  2. 2. Prevention of intimal hyperplasia after balloon angioplasty and / or stent insertion. or How to mend a broken heart - Just say NO

    Författare :Jan Harnek; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Remodeling. Endothelium-derived factors. Self-expanding stents. Restenosis. Scanning -electron microscopy. Endothelial factors. Nitric oxide. Intimal hyperplasia. Angioplasty. Stents. Interventional procedures. Endothelium.;

    Sammanfattning : Background: Restenosis is the most frequently occurring adverse event after percutaneous intravascular treatment of atherosclerotic lesions, which limits long-term patency of the intervention. Objective: The aim of the study was to evaluate if minimizing vascular injury during treatment by insertion of self-expanding stents or modifying the reparative mechanisms by local drug delivery can reduce restenosis.

  3. 3. Studies on Prostanoid Production in the Umbilicoplacental Circulation

    Författare :Pia Saldeen; Malmö Reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; Obstetrics; Umbilical; Thromboxane; Pulsatility Index; Prostacyclin; Pregnancy; Placenta; Peroxidation; Growth restriction; Endoperoxides; Endothelium; Doppler; Diabetes; sexualitet; reproduktion; andrologi; gynekologi; andrology; reproduction; sexuality; Obstetrik;

    Sammanfattning : The fetoplacental circulation is a low pressure system with a high vascular prostacyclin to thromboxane (Pc/Tx)synthesis ratio. In intrauterin growth restriction (IUGR) and diabetes the prostanoid balance may be altered. LÄS MER

  4. 4. Pathophysiological and Histomorphological Effects of One-Lung Ventilation in the Porcine Lung

    Författare :Alf Kozian; Göran Hedenstierna; Thomas Hachenberg; Filip Freden; Sten Walther; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alveolar Recruitment Manoeuvre; One-Lung Ventilation; Lung Protective Ventilation; Tidal Volume; Computed Tomography; Tidal Recruitment; Animal Model; Open Thoracic Surgery; Ventilation Perfusion Distribution; Single Photon Emission Computed Tomography; Diffuse Alveolar Damage; Medical laboratory science; Medicinsk laboratorievetenskap; Anestesiologi; Anaesthesiology;

    Sammanfattning : Thoracic surgical procedures require partial or complete airway separation and the opportunity to exclude one lung from ventilation (one-lung ventilation, OLV). OLV is commonly associated with profound pathophysiological changes that may affect the postoperative outcome. LÄS MER

  5. 5. On guided bone regeneration using ceramic membranes

    Författare :Jonas Anderud; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Regeneration of bone in the oral and maxillofacial region can beachieved with different techniques such as autologous bone grafts,bone substitutes and guided bone regeneration. Guided boneregeneration is defined as creating a space between the bone and itssurrounding tissues, using a barrier that allows new bone to migrateinto the space while preventing other cell types from interfering.
