  1. 6. Analysis of the vascular sounds of the arteriovenous fistula

    Author : Marco Munguia Mena; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This licentiate thesis is in the field of biomedical signal processing with main focus on processing of the vascular sounds of the hemodialysis vascular access in patient undergoing hemodialysis. The first paper proposes a feature extraction method based on principal component analysis (PCA) for acoustic detection of venous stenosis. READ MORE

  2. 7. Phenotypic modulation of vascular smooth muscle in organ culture

    University dissertation from BMC Biomedical Centre, Lund University

    Author : Anders Lindqvist; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smooth muscle; proliferation; PDGF; Physiology; energy metabolism; calcium; Fysiologi;

    Abstract : Contraction of blood vessels for the regulation of blood flow and pressure is dependent on vascular smooth muscle cells (VSMC) located in the medial layer of the vascular wall. Adult, differentiated VSMC have a well developed contractile system and a low rate of proliferation. READ MORE

  3. 8. Sex steroids, IGF-I, and vascular morphology from birth to adulthood in individuals born small for gestational age

    University dissertation from Göteborgs universitet

    Author : Kerstin Allvin; Göteborgs universitet.; Gothenburg University.; [2020]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small for gestational age; preterm; sex steroid; estradiol; testosterone; dihydrotestosterone; glucocorticoid; retina; IGF-I;

    Abstract : Abstract Aim: To study whether there is an association between size at birth, sex steroids, IGF-I, and retinal vascular morphology. Patients and methods: Two different cohorts were studied. In paper I, 25 young adult men born small for gestational age (SGA) were compared to 44 young adult men born appropriate for gestational age (AGA). READ MORE

  4. 9. Vascular Wall Responses to Bypass Grafting - Studies in Mice

    University dissertation from Göteborgs universitet

    Author : Klas Österberg; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intimal hyperplasia; graft stenosis; smooth muscle cells; mice; cellular recruitment;

    Abstract : Abstract Vein grafts are frequently used in bypass surgery for treatment of coronary artery disease and lower limb ischemia. Unfortunately the long-term patency is impaired by vein graft stenoses due to intimal hyperplasia (IH). It is assumed that exaggerated intimal thickening is initiated by vessel wall injuries or local flow disturbances. READ MORE

  5. 10. Molecular Mechanisms in Vascular Endothelin B Receptor Up-Regulation

    University dissertation from Erik Uddman, BMC A13, 221 84, Lund

    Author : Erik Uddman; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; reverse; in vitro pharmacology; organ culture; Endothelin receptors; up-regulation;

    Abstract : Cardiovascular diseases are characterized by changes in morphology and function of the blood vessels. Different signalling molecules are involved in these changes. Endothelin-1 (ET-1) is one of the most potent signalling molecules found in man. Its actions are mediated by two receptors, the ETA and the ETB receptors. READ MORE
