  1. 1. Vessel wall integrity : influence of genetics and flow

    Författare :Hanna Björck; Toste Länne; Per Eriksson; Sverker Jern; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular disease (CVD) is the major cause of death worldwide. Underlying causes, such as atherosclerosis and hypertension, are associated with remodeling of the vessel wall ultimately leading to loss of structural integrity. There are a number of factors that can influence vascular remodeling and hence structural integrity. LÄS MER

  3. 2. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

    Författare :Hans Kolsters; KTH; []
    Nyckelord :Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

    Sammanfattning : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.

  4. 3. Effects of physical exercise on coronary and peripheral vascular function. An integrative physiological study from rat to man

    Författare :Ulrika Hägg Samuelsson; Göteborgs universitet; []
    Nyckelord :exercise; endothelial function; coronary flow velocity reserve; colour Doppler echocardiography; oxidative stress; gene expression; stiffness; ultrasound biomicroscopy;

    Sammanfattning : Physical exercise is beneficial for the cardiovascular health. Numerous epidemiological studies reveal that physical activity reduces the risk of cardiovascular related death. Nevertheless, the underlying vessel wall specific physiological and molecular mechanisms still remain incompletely understood. LÄS MER

  5. 4. Arterial stiffness and risk factors for cardiovascular disease in young adults

    Författare :Ulrika Fernberg; Anita Hurtig-Wennlöf; Maria Fernström; Bo Fernhall; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; atherosclerosis; arterial stiffness; pulse wave analysis; intima media thickness; cardiorespiratory fitness; physical activity; body composition; young adults;

    Sammanfattning : Atherosclerosis is a complex, chronic vessel wall disease that often leads to severe and acute cardiovascular diseases (CVD), such as myocardial infarction and stroke. CVD are the most common cause of death, both globally and in Sweden. LÄS MER

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

    Författare :Jana Brodszki; Lund Obstetrik och gynekologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
