  2. 16. Surgical trauma, inflammation and tissue injury

    Author : Leif Törkvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Activated partial thromboplastin time; blood flow; blood pressure; CD18; calcitonin gene-related peptide; dalteparin; glucocorticoids; heparin; intravital microscopy; leukotrienes; myeloperoxidase; neutrophils; stress; surgical flaps; rat;

    Abstract : Surgical tissue trauma is a strong stimulus for local inflammation, including leukocyte recruitment. While such a response may be of importance for the defense against microorganisms, it is also clear that inflammation may contribute to further tissue injury. READ MORE

  4. 17. Experimental skin flaps and nitric oxide

    Author : Örjan Gribbe; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Surgical flaps; nitric oxide; ischemia; reperfusion; nitrite; laser Doppler; transit-time ultrasound flowmetry; electron microscopy; NO donors; NOS inhibitors;

    Abstract : Surgical flaps are used in plastic surgery to reconstruct tissue defects due to trauma or cancer removal. Occasionally flaps are subjected to ischemia and reperfusion injury leading to flap failure. READ MORE

  5. 18. The enzymatic machinery of leukotriene biosynthesis : Studies on ontogenic expression, interactions and function

    Author : Tobias Strid; Sven Hammarström; Mats Söderström; Ralf Morgenstern; Linköpings universitet; []
    Keywords : ;

    Abstract : Leukotrienes (LTs) are biologically active arachidonic acid (AA) derivatives generated by the 5-lipoxygenase (5-LO) pathway. They are produced by myeloid cells. 5-LO converts AA to LTA4 in cooperation with 5-LO activating protein (FLAP). LTA4 is converted to LTB4, by LTA4-hydrolase (LTA4H) or to LTC4 by LTC4-synthase (LTC4S). READ MORE

  6. 19. Microcirculation in tissue repair - from microsurgery to 3D bioprinting

    Author : Matteo Amoroso; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microsurgery; 3D bioprinting;

    Abstract : Microsurgical reconstruction is challenged by two main shortcomings: Perfusion Related Complication (PRC) and donor site morbidity. In the first 3 studies of this thesis, we aimed to provide solutions to PRC-problems, investigating hemodilution as a tool able to increase blood flow in flap microcirculation. READ MORE

  7. 20. Laser Speckle Contrast Imaging in Reconstructive Surgery

    Author : Johan Zötterman; Simon Farnebo; Erik Tesselaar; Jacob Wikner; Henry Svensson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : ObjectivesReconstructive surgery aims to restore function or normal appearance by reconstructing defective organs after trauma or disease. In patients undergoing reconstructive surgery, previous trauma, surgery or radiotherapy can result in compromised blood supply. READ MORE
