  1. 1. Vascular Effects of P2 Receptors. Changes in Congestive Heart Failure

    Författare :Malin Malmsjö; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; congestive heart failure; pyrimidine; purine; P2 receptor; vasodilatation; vasoconstriction; hyperpolarisation; EDHF; NO; Vascular; endothelium; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Extracellular nucleotides induce dilatation and constriction of blood vessels by activation of P2 receptors. In this thesis the vasomotor effects of P2 receptor activation were studied in the rat mesenteric artery, and their changes in congestive heart failure (CHF) were evaluated using in vitro pharmacology, electrophysiology and competitive RT-PCR.

  3. 2. 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

  4. 3. Vascular actions of antimicrobial peptides

    Författare :Cristina Ciornei; Sektion II; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; vascular smooth muscle; sepsis; nitric oxide; human antimicrobial peptide LL-37; Antimicrobial peptides; lipopolysaccharide; bactericidal permeability-increasing protein;

    Sammanfattning : The present thesis focuses on the vascular effects of antimicrobial peptides especially mechanisms involving the vasodilator nitric oxide (NO), which is released from the blood vessel wall during inflammatory conditions such as sepsis. Bacterial lipopolysaccharide stimulates the expression of nitric oxide synthase (iNOS), which increases the NO production in vascular tissues or cultured vascular smooth muscle cells (VSMC). LÄS MER

  5. 4. The Plasma Contact System : New Functional Insights from a Hemostatic and Thrombotic Perspective

    Författare :Jennie Bäck; Bo Nilsson; Kristina Nilsson Ekdahl; Ulla Hedner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Contact activation; factor XII; platelets; coagulation; antithrombin; C1 inhibitor; hemostasis; biomarkers; vascular disease.; Klinisk immunologi; Clinical Immunology;

    Sammanfattning : The physiological role of the plasma contact system still remains a partial enigma. The aim of the presented work was to expand our understanding of the plasma contact system, focusing on its physiological activation and function, principally from a hemostatic perspective. It also explored contact system activation under pathological conditions. LÄS MER

  7. 5. Lymphatic Vascular Morphogenesis : From Progenitors to Functional Vessels

    Författare :Nina Daubel; Taija Mäkinen; Markus Affolter; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lymphatic vasculature; morphogenesis; lymphvasculogenesis; mesentery; lymphatic capillary;

    Sammanfattning : The lymphatic vasculature is an important part of the circulatory system and crucial for normal functioning and maintenance of tissues. Yet, our understanding of the processes underlying lymphatic development and homeostasis are surprisingly limited. LÄS MER
