  2. 1. Effects of oestrogen on haemodynamic and vascular reactivity - A study in animal models and humans

    Author : Lisa Brandin; Göteborgs universitet; []
    Keywords : adrenergic reactivity; endothelium; haemodynamic; hypertension; oestrogen; postmenopausal women; resistance arteries; spontaneously hypertensive rats; stress;

    Abstract : Effects of Oestrogen on Haemodynamic and Vascular Reactivity A study in animal models and humans Lisa Brandin Institute of Medicine, Department of Emergency and Cardiovascular Medicine, Sahlgrenska University Hospital/Östra, Sahlgrenska Academy, Göteborg University, Göteborg, Sweden ABSTRACT Previous studies have shown that oestrogen, the female sex hormone, plays a protective role in the cardiovascular system. However the site of action remains incompletely understood. READ MORE

  4. 2. Mechanosensing in the vascular wall - the role of cellular microdomains in vascular remodeling

    Author : Sebastian Albinsson; Kärlfysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; cytochemistry; histochemistry; wall stress; shear stress; hypertension; Histology; differentiation; growth; caveolin; smooth muscle; actin; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : The vascular wall has a remarkable capacity to adapt to mechanical forces exerted by the intraluminal blood pressure and flow. This includes rapid change in contractile tone as well as chronic alteration of vessel structure if the stimulus persists. Stretch of the intact blood vessel wall promotes growth and contractile differentiation. READ MORE

  5. 3. Impairment of Endothelial Thromboprotective Function by Haemodynamic and Inflammatory Stress - Implications for hypertensive disease

    Author : Erik Ulfhammer; Göteborgs universitet; []
    Keywords : tissue-type plasminogen activator; endothelium; fibrinolysis; hypertension; shear stress; strain; antihypertensive agents; inflammation; TNF-alpha; NF-kappaB; MAPK;

    Abstract : The physiologically most important activator of intravascular fibrinolysis is tissue-type plasminogen activator (t-PA). The endothelium synthesizes and stores t-PA and regulated release of the enzyme is an important local protective response to prevent thrombus extension. READ MORE

  6. 4. Blood Pressure Elevation - Impact on Cardiovascular Structure and Endogenous Fibrinolysis

    Author : Wilhelm Ridderstråle; Göteborgs universitet; []
    Keywords : hypertension; left ventricular hypertrophy; intima-media thickness; fibrinolysis; endothelium; tissue plasminogen activator; antihypertensive agents; mechanical stress; plasminogen activator inhibitor-1;

    Abstract : Blood pressure elevation is a major risk factor for cardiovascular events and the risk increases in a dose-dependant manner. It is of importance to identify subjects prone to develop hypertension and adverse cardiovascular remodeling in order to start treatment timely. READ MORE

  7. 5. Mental Stress and Endothelium-Dependent Vasodilation

    Author : Kristina Johansson; Sverker Jern; Uppsala universitet; []
    Keywords : Medical sciences; Mental stress; endothelium; adrenoceptor blockade; catecholamine; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : The endothelium plays an important part in blood flow regulation by producing the vasodilatory substance nitric oxide (NO). Various studies have shown that commonly accepted risk factors for coronary heart disease, such as hypertension, diabetes, hypercholesterolemia, smoking and mental stress impair endothelium-derived vasodilation by the NO-pathway.
