  1. 6. Giant cell arteritis. Epidemiological, morphological and molecular genetic studies

    Författare :Vigdís Pétursdóttir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giant cell arteritis; temporal artery; aorta; epidemiology; atrophy; calcification; estrogen receptor a; morphometry; immunocytochemistry; Western blot; molecular genetics;

    Sammanfattning : Giant cell arteritis (GCA) is a chronic inflammatory disorder of unknown etiology, affecting large and medium-sized arteries, predominantly in postmenopausal women. Its pathogenesis is probably multifactorial. Several studies suggest that GCA is an antigen-driven disease. LÄS MER

  3. 7. Assessing carotid plaque structure

    Författare :Isabel Goncalves; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Kardiovaskulära systemet; Modified LDL; Antibodies; Lipids; AP-1; Cellularity; Extracellular Matrix; Calcification; Elastin; Stroke; Gray-Scale Median; Echogenicity; Ultrasound; Atherosclerosis; Carotid Plaque;

    Sammanfattning : Atherosclerosis is the leading cause of death and disability in the western world. Its clinical complications include acute myocardial infarction, sudden death and stroke. Thirty to 40 % of all ischemic strokes are caused by a carotid stenosis. LÄS MER

  4. 8. Calcareous Algae of a Tropical Lagoon : Primary Productivity, Calcification and Carbonate Production

    Författare :Juma W. Kangwe; Mats Björk; Lena Kautsky; Ian Bryceson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi;

    Sammanfattning : The green algae of the genus Halimeda Lamouroux (Chlorophyta, Bryopsidales) and the encrusting loose-lying red coralline algae (Rhodophyta, Corallinales) known as rhodoliths are abundant and widespread in all oceans. They significantly contribute to primary productivity while alive and production of CaCO3 rich sediment materials on death and decay. LÄS MER

  5. 9. The emergence of pelagic calcification and its influence on seawater chemistry in the Upper Triassic

    Författare :Isaline Demangel; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Calcareous nannofossils; Triassic; Neo-Tethys Ocean; Pelagic calcification;

    Sammanfattning : After the early biomineralisation event in the early Paleozoic (Cambrian –Ordovician; 541 – 443.8 Ma), the Late Triassic (237 – 201.3 Ma) represents another key period of biomineralisation with the onset of the Mesozoic plankton radiation. LÄS MER

  7. 10. Insights into the relationship between coronary calcification and atherosclerosis risk factors

    Författare :Rachel Nicoll; Michael Henein; Gunilla Olivecrona; Jan Engvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary artery calcification; risk factors; atherosclerosis; stenosis; Cardiology; kardiologi;

    Sammanfattning : Introduction Coronary artery disease (CAD) is the most common cause of death in Europe and North America and early detection of atherosclerosis is a clinical priority. Diagnosis of CAD remains conventional angiography, although recent technology has introduced non-invasive imaging of coronary arteries using computed tomographic coronary angiography (CTCA), which enables the detection and quantification of coronary artery calcification (CAC).
