  1. 26. The effect of hypoxia on macrophage proteoglycans: potential role in atherosclerosis

    Författare :Annika Asplund; Göteborgs universitet; []
    Nyckelord :atherosclerosis; proteoglycans; glycosaminoglycans; macrophages; hypoxia; hypoxia-inducible transcription factor; LDL binding; cell motility;

    Sammanfattning : A critical step in the development of atherosclerotic lesions appears to be the retention of low density lipoproteins (LDL) in the arterial wall, mediated by negatively charged proteoglycans (PG). Retained LDL is susceptible to modification and uptake by resident macrophages that are found in hypoxic sites in atherosclerotic lesions (with oxygen levels below 1%). LÄS MER

  3. 27. 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).

  4. 28. Angiotensin II and vascular disease. Studies in rats and atherosclerosis-prone mice

    Författare :Maria E Johansson; Göteborgs universitet; []
    Nyckelord :angiotensin II; atherosclerosis; AT1 receptor; AT2 receptor; blood pressure; hyperinsulinemia; hypertension; oxidative stress; salt; vascular disease; vascular function;

    Sammanfattning : Angiotensin II (Ang II) is of importance for a number of physiological processes but also plays an important pathophysiological role in cardiovascular disease. The aim of this thesis was to evaluate the role of Ang II in hypertension-related atherosclerosis and vascular disease and to investigate possible anti-atherosclerotic effects of the angiotensin II, type 2 (AT2) receptor.

  5. 29. Atherosclerosis in 64-year-old women with diabetes mellitus and impaired glucose tolerance

    Författare :Gerhard Brohall; Göteborgs universitet; []
    Nyckelord :Systematic review; Atherosclerosis; Type-2 diabetes; IMT; Vascular remodelling; IGT;

    Sammanfattning : Atherosclerosis in 64-year-old women with diabetes mellitus and impaired glucose tolerance The incidence of obesity and type-2 diabetes (t2D) is rising around the world. T2D is accompanied by an increased risk of macrovascular, atherosclerotic diseases. LÄS MER

  7. 30. The role of PPARalpha and growth hormone in hepatic lipid metaboism and atherosclerosis

    Författare :Anna Ljungberg; Göteborgs universitet; []
    Nyckelord :growth hormone; PPARalpha; atherosclerosis; lipid metabolism; fatty acids; apoB; ; ADRP; triglycerides; PGC-1; liver;

    Sammanfattning : Dyslipidemia mainly results from oversecretion of apoB-containing lipoproteins from theliver and is one of the most important risk factors for the development of atherosclerosis.Growth hormone (GH) plays a key role in the regulation of lipoprotein metabolism and thus,disturbances in GH secretion are associated with dyslipidemia and cardiovascular disease.
