  1. 21. Engineering the shape of bacterial cellulose and its use as blood vessel replacement

    Författare :Henrik Bäckdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tissue engineering.; smooth muscle cells; bacterial cellulose; scaffold design; tubular fermentation; biocompatibility evaluation; Blood vessel; vascular graft;

    Sammanfattning : Tissue loss and organ failure are major health problems that impose great costs on society. Cardiovascular diseases are responsible for 36% of mortalities and the disease burden among adults over the age of 60. The single largest cardiovascular disease is atherosclerosis in the coronary artery. LÄS MER

  3. 22. Non-Invasive Measures of Heart Failure

    Författare :Mikael Kanski; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; diagnosis; magnetic resonance imaging; blood flow; 4D flow; pulmonary blood volume; kinetic energy;

    Sammanfattning : Heart failure is a clinical syndrome characterized by an inability of the heart to meet the metabolic demands of the body. Approximately 1-2% of the population in the western society has the diagnosis, and the 5-year mortality rate is comparable with the common cancer diagnoses. LÄS MER

  4. 23. The significance of blood vessels in organogenesis and cadherins in exploratory behaviour

    Författare :Josefina Edsbagge; Göteborgs universitet; []
    Nyckelord :pancreas; sphingosine-1-phosphate; endothelium; epithelial-to-mesenchymal interactions; ; Cre loxP-system; cadherins; rearing;

    Sammanfattning : Organogenesis of epithelial organs requires interaction between epithelial andmesenchymal tissues. In pancreas development three different mesenchymal derivedstructures, the notochord, the endothelial cells and the splanchnic mesenchyme inducespecification, growth and further differentiation of the pancreatic epithelium.

  5. 24. Blood flow specific assessment of ventricular function : Visualization and quantification using 4D flow CMR

    Författare :Alexandru Grigorescu Fredriksson; Carljohan Carlhäll; Bengt Johansson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The spectrum of cardiovascular diseases is the leading cause of morbidity and mortality globally. Early assessment and treatment of these conditions, acquired as well as congenital, is therefore of paramount importance. The human heart has a great ability to adapt to various hemodynamic conditions by cardiac remodeling.

  7. 25. On the Autonomic Control of Blood Flow and Secretion in Salivary Glands. Functional and morphological aspects on muscarinic receptor subtypes in different species

    Författare :Anders Ryberg; Göteborgs universitet; []
    Nyckelord :Muscarinic receptor subtype; neuronal; non-neuronal; expression; secretion; blood flow; salivary gland; human; rat; sheep;

    Sammanfattning : Parasympathetic nervous activity is the principal stimulus for evoking fluid responses within salivary glands. Concomitantly to the onset of this response, the blood flow increases. LÄS MER
