1. 1. Vascular ultrasound for the assessment of carotid atherosclerosis

   Författare :Davide Vanoli; Per Lindqvist; Christine Kremer; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrasound; Plaque; IMT; Atherosclerosis; CEUS; Carotid vessels; cardiovascular disease; hjärt- och kärlforskning;

   Sammanfattning : Background: Atherosclerotic cardiovascular disease (CVD) is a common cause for mortality globally, and is expected to remain the single leading cause of death as the global population ages and as life expectancy increases.Cardiovascular screening models have been developed, and continue to be developed, to identify individuals at high-risk of CVD.

3. 2. Artery Wall Imaging and Effects of Postmenopausal Estrogen Therapy

   Författare :Kenny A. Rodriguez-Macias Wallberg; Tord Naessén; Lars-Åke Mattsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; artery wall thickness; tunica media; tunica intima; arterial stiffness; carotid; aorta; cardiovascular disease; atherosclerosis; menopause; estrogen; hormone therapy; ultrasound; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Sammanfattning : Postmenopausal estrogen therapy, initiated early in the menopause, seems to protect against development of atherosclerosis and cardiovascular diseases. This thesis concerns studies of artery wall thickness and arterial stiffness estimated by noninvasive ultrasound techniques in long-term estrogen treated postmenopausal women who initiated therapy at the time of the menopause.

4. 3. Inflammation in atherosclerosis

   Författare :Ken Jatta; Allan Sirsjö; Michael D. Menger; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atherosclerosis; chemokine; cytokine; inflammation; Lipopolysacchride; Carotid lesion; interleukin; viperin Cig5; smooth muscle cells; Cardiovascular medicine; Kardiovaskulär medicin; MEDICINE; MEDICIN; Biomedicin; Biomedicine;

   Sammanfattning : Consequences of atherosclerosis may result in a number of diseases of the cardiovascular system that represent serious health problems and major causes of morbidity and mortality worldwide. Although it is initially considered as disease of fibro-lipid and thrombus deposition in the arterial wall, it also involves an ongoing inflammatory response. LÄS MER

5. 4. Mechanochemical Modeling of Smooth Muscle Activation

   Författare :Sae-Il Murtada; Gerhard A. Holzapfel; Robert McMeeking; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomechanics; Muscle contraction; Smooth muscle; Contractile unit; Filament overlap; Intracellular calcium; Carotid artery; Mathematical model;

   Sammanfattning : Smooth muscle has an important role in several physiological processes, where it regulates the wall tension and the size of hollow organs. In blood vessels, the contraction and relaxation of smooth muscle contribute to the mechanical stability of the vessel wall and determines the diameter. LÄS MER

7. 5. Vascular Dysfunction in Stroke and CADASIL

   Författare :Anna Stenborg; Lars Lind; Andreas Terent; Toste Länne; Uppsala universitet; []
   Nyckelord :Internal medicine; stroke; CADASIL; endothelium; vasodilation; Invärtesmedicin;

   Sammanfattning : Cerebrovascular disease (CVD) is strongly linked to hypertension and generally occurs later in life than coronary artery disease (CAD). Three quarters of the patients with symptomatic CVD are above 65 years of age. The risk factors are the same for CVD and CAD, but the relative importance of the vascular risk factors differs greatly.
