1. Investigation of the origin of the coronary artery calcification process and its relationship to the atherosclerotic cardiovascular disease
Sammanfattning : The objectives of this thesis are: a) To examine racial/ethnic differences in coronary artery calcification (CAC) and CAD, between symptomatic South Asians and Caucasians, matched for age, gender and conventional cardiovascular risk factors, b) To assess, using a meta-analysis model, the natural history of and stability of measurements of coronary artery calcium scoring (CACs) based on data collected from two large published trials: St Francis and EBEAT, c) To investigate the prevalence of coronary artery calcification in individuals with CT evidence for AVC, mitral valve calcification (MAC) or of both of them (AVC+MAC), d) To assess any potential association between premature CAD (..

2. Molecular mechanisms of cardiovascular calcification
Sammanfattning : Cardiovascular calcification is a pathophysiological process characterized by the deposition of calcium-phosphate crystals in the arteries and the leaflets of the heart valves. In the arteries calcification causes arterial stiffness, which may lead to poor cardiac perfusion, systolic hypertension and heart failure. LÄS MER
3. Carotid artery disease : plaque features and vulnerability
Sammanfattning : Background: Atherosclerosis is an important cause of stroke. Ultrasound offers the convenience of real-time and detailed assessment of carotid plaque features as well as arterial wall thickening and composition. LÄS MER
4. Carotid calcifications in panoramic radiographs in relation to carotid stenosis
Sammanfattning : Calcifications in carotid atheromas can be detected in a panoramic radiograph (PR) of the jaws. A carotid artery calcification (CAC) can indicate presence of significant (≥ 50%) carotid stenosis (SCS). LÄS MER
5. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities
Sammanfattning : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. LÄS MER
