  2. 26. On the Use of Ultrasound Phase Data for Arterial Characterization

    Author : Tobias Erlöv; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atherosclerosis; Ultrasound; Carotid Artery; Plaque Characterization; Scatter Size; Longitudinal Movement; Intima-Media Thickness;

    Abstract : Atherosclerosis is one of the major causes of death in the world. It is an inflammatory disease in the arteries which causes a gradual increase in arterial wall thickness and stiffness. Eventually a plaque could be formed, protruding into the artery and partially occluding the blood flow. READ MORE

  4. 27. Distensibility in Arteries, Arterioles and Veins in Humans : Adaptation to Intermittent or Prolonged Change in Regional Intravascular Pressure

    Author : Roger Kölegård; Ola Eiken; Toste Länne; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arterial stiffness; venous distensibility; venous flow characteristics; bedrest; pressure training; Physiology; Fysiologi;

    Abstract : The present series of in vivo experiments in healthy subjects, were performed to investigate wall stiffness in peripheral vessels and how this modality adapts to iterative increments or sustained reductions in local intravascular pressures. Vascular stiffness was measured as changes in arterial and venous diameters, and in arterial flow, during graded increments in distending pressures in the vasculature of an arm or a lower leg.

  5. 28. Vascular mechanical properties and endothelial function with special reference to pregnancy and hormonal influences

    Author : Jana Brodszki; Lund Obstetrik och gynekologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; Obstetrics; systemic lupus erythematosus; hormone therapy; preeclampsia; pregnancy; endothelial function; arterial stiffness; vessels; ultrasound; cardiovascular disease;

    Abstract : Cardiovascular disease (CVD) is one of the leading causes of mortality and morbidity. Early recognition of vascular changes, both structural and functional, may help to identify individuals at risk for CVD. READ MORE

  6. 29. Methodological studies applying new techniques for evaluation of arterial function

    Author : Margareta Ring; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Atherosclerotic cardiovascular disease is the most common cause of death in the Western world today. Atherosclerosis in the arterial wall is related to aging and the inflammatory and calcification processes, and is influenced by risk factors such as smoking, male gender, diabetes, hypertension, obesity, stress, inactivity, hyperlipidemia, and genetic factors.

  7. 30. Vascular Endothelin and Angiotensin Receptors Regulation in Inflammatory Arterial Disorders

    Author : Ivan Dimitrijevic; Lund Medicin; []
    Keywords : 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;

    Abstract : 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). READ MORE
