  1. 1. Novel functions of cardiovascular P2 receptors

    Författare :Anna-Karin Wihlborg; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Kardiovaskulära systemet; mRNA; EDHF; UTP; UDP; ADP; ATP; P2 receptor; contraction; dilatation; endothelial cells; Heart; VSMC;

    Sammanfattning : The aim of the thesis was to examine the expression and function of the extracellular nucleotide P2 receptors in the cardiovascular system. In the cardiovascular system nucleotides are released during shear stress, hypoxia, ischemia, from endothelial cells, smooth muscle cells, aggregating platelets, inflammatory cells and erythrocytes.

  2. 2. Acute cardiovascular effects of biofuel exhaust exposure

    Författare :Jon Unosson; Jenny A Bosson; Anders Blomberg; Jeremy P Langrish; Campen Matthew; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular; air pollution; endothelial dyssfunction; arterial stiffness; wood smoke; woodsmoke; biodiesel; RME; biofuel; diesel exhaust;

    Sammanfattning : BackgroundAnthropogenic air pollution is a global health problem estimated to contribute to millions of premature deaths. Exposure to biomass smoke is common due to varying sources, such as wildfires, indoor cooking over open fires, and residential heating from wood stoves. LÄS MER

  3. 3. Genetic studies on cardiovascular disease - identification of novel drug targets

    Författare :Stefan Amisten; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Medicin människa och djur ; Medicine human and vertebrates ; platelet; single nucleotide polymorphism; myocardial infarction; stent; G-protein coupled receptor; P2Y; cytogenetics; Genetik; cytogenetik; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : The aim of this thesis was to identify novel potential drug targets of cardiovascular disease with a focus on G-protein coupled receptors. We identified a common genetic variant of the ATP receptor P2Y11, where an alanine is substituted with a threonine at position 87 of the P2Y11 receptor that increases the risk of developing acute myocardial infarction.

  4. 4. Experimental and Clinical Studies on Platelet Receptors in Cardiovascular Disease

    Författare :Oscar Braun; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; inflammation; athersosclerosis; platelets; thrombosis; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : The crucial role of platelets in maintaining primary hemostais has been evident for a long time and there is now also mounting evidence for their involvement in inflammation. In combination with aspirin, inhibition of the platelet P2Y12 ADP receptor with clopidogrel has become a cornerstone in the antiplatelet in acute coronary syndromes. LÄS MER

  5. 5. Cardiovascular regulation in women with vasovagal syncope : With special reference to the venous system

    Författare :Johan Skoog; Toste Länne; Marcus Lindenberger; Helene Zachrisson; Ola Eiken; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Although vasovagal syncope (VVS) is a common clinical condition the mechanisms behind VVS remain elusive. Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. LÄS MER
