  1. 16. On endovascular methods for cell transplantation : exploring the selective intra-arterial and trans-vessel wall routes

    Författare :H Johan Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Cell based transplantation methods are a pivotal part of the emerging field of regenerative medicine. These transplantation methods could possible produce curative treatments where, previously, expectations of such feats were low. Diseases for which treatments are evaluated are in such diverging physiological systems as e.g. LÄS MER

  3. 17. Regulation of gene expression in the vascular wall

    Författare :Erik Larsson; Göteborgs universitet; []
    Nyckelord :smooth muscle; endothelium; angiogenesis; SRF; myocardin; LPP; gene regulation; genetics; microRNA;

    Sammanfattning : Blood vessel growth and function are closely related to a number of pathological conditions, including tumor angiogenesis, wound healing and atherosclerosis. Smooth muscle cells (SMC) and endothelial cells (EC), the two major constituents of the vascular wall, are both characterized by the expression of unique phenotypic marker genes, many of which have vital roles in blood vessel development and disease.

  4. 18. Vascular Wall Responses to Bypass Grafting - Studies in Mice

    Författare :Klas Österberg; Göteborgs universitet; []
    Nyckelord :Intimal hyperplasia; graft stenosis; smooth muscle cells; mice; cellular recruitment;

    Sammanfattning : Abstract Vein grafts are frequently used in bypass surgery for treatment of coronary artery disease and lower limb ischemia. Unfortunately the long-term patency is impaired by vein graft stenoses due to intimal hyperplasia (IH). It is assumed that exaggerated intimal thickening is initiated by vessel wall injuries or local flow disturbances. LÄS MER

  5. 19. Turbulent Flow in Constricted Blood Vessels : Quantification of Wall Shear Stress Using Large Eddy Simulation

    Författare :Roland Gårdhagen; Matts Karlsson; Toste Länne; Leif Rune Hellevik; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The genesis of atherosclerosis has previously been shown to be affected by the frictional load from the blood on the vessel wall, called the wall shear stress (WSS). Assessment of WSS can therefore provide important information for diagnoses, intervention planning, and follow‐up. LÄS MER

  7. 20. Fluid Mechanics of Solid-Liquid Suspensions – An Experimental and Numerical Study

    Författare :Torbjörn Virdung; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiphase; soalescence; confined jet; computational fluid dynamics; stirred vessel; laser doppler velocimetry; particle image velocimetry; solid-liquid suspension; pitched blade; gas-liquid;

    Sammanfattning : Multiphase flows are common in many applications in chemical, mineral, biochemical and several other process industries. Examples of equipment in which multiphase flows are encountered are stirred vessels and multiphase jets, in which suspensions are agitated by an impeller in the former case and distributed through a nozzle in the latter.
