  1. 11. Vascular Endothelin and Angiotensin Receptors Regulation in Inflammatory Arterial Disorders

    Författare :Ivan Dimitrijevic; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ischemic heart disease; resistance artery; giant cell arteritis; temporal artery; immunohistochemistry; AT2 receptor; AT1 receptor; Endothelin-1; ETA receptor; ETB receptor;

    Sammanfattning : The present thesis is aimed to examine the hypothesis that the degree of vascular inflammation correlates with the expression of vascular endothelin and angiotensin receptors. The receptor changes were studied in subcutaneous resistance arteries in patients with different degrees of ischemic heart disease (IHD). LÄS MER

  3. 12. Macro- and microvascular complications of diabetes: Studies on NFAT (Nuclear Factor of Activated T-cells) as a novel target for the treatment of atherosclerosis and vascular dysfunction in diabetes

    Författare :Fabiana Blanco; Diabetiska komplikationer; []
    Nyckelord :NFAT; VSMCs; Diabetes; Hyperglycemia; Aterosclerosis; Diabetic retinopathy; Oxidative stress;

    Sammanfattning : Diabetes is associated with devastating chronic complications including coronary heart disease and stroke (macrovascular complications) as well as microvascular disorders leading to damage of the small vessels and the development of retinopathy, nephropathy and neuropathy. The underlying pathogenesis is not clear, but hyperglycemia has been identified as an important risk factor. LÄS MER

  4. 13. Challenging the mystique Connection. Deciphering cell-matrix interactions role in atherosclerosis and restenosis

    Författare :Vignesh Murugesan; Kärlväggsbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dystrophin glycoprotein complex; beta-sarcoglycan; dystrophin; Plaque; vascular smooth muscle cells; atherosclerosis; restenosis;

    Sammanfattning : Atherosclerosis is the underlying cause for myocardal infarction, stroke and peripheral arterial disease, collectively referred to as cardiovascular diseases. These represent the major cause of death globally. LÄS MER

  5. 14. Tumor angiogenesis. Regulation of mural cell recruitment and endothelial sprouting

    Författare :Alexandra Abramsson; Göteborgs universitet; []
    Nyckelord :Angiogenesis; tumor; retina; PDGF; VEGF; platelet-derived growth factor; guidance; vascular endothelial growth factor.;

    Sammanfattning : The formation of new blood vessels is an inherent part of many physiological and pathological processes. Currently, there is a strong hope pathological situations like stroke, diabetic retinopathy and cancer may be affected by pharmacological regulators of blood vessel formation. LÄS MER

  7. 15. Neuropeptide Y - aspects of vasomotorresponses and receptor characterization

    Författare :Torun Nilsson-Bergdahl; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vasoconstriction; RT-PCR; receptor characterization; potentiation; NPY Y1 receptor; NPY; mitogenesis; hypertension; human arteries; forearm blood flow; cell culture; antisense oligodeoxynucleotides; BIBP3226; vasodilatation.; Physiology; Fysiologi; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Abstract The aims of the present thesis were to examine neuropeptide Y (NPY) responses in different human and guinea pig vascular beds and in cultured human vascular smooth muscle cells (VSMC) and to characterize, with different NPY agonists and the specific NPY Y1 receptor antagonist (BIBP3226), the NPY receptors involved. NPY-induced strong and potent contractions in human cerebral and subcutaneous arteries and in guinea pig basilar arteries. LÄS MER
