  2. 1. The role of the adventitia and perivascular tissue for the formation of intimal hyperplasia

    Author : Per Fogelstrand; Göteborgs universitet; []
    Keywords : Intimal hyperplasia; adventitia; perivascular tissue; smooth muscle cells; fibroblasts; balloon injury; vein graft; artificial graft;

    Abstract : Symptomatic atherosclerosis is commonly treated with balloon angioplasty or bypass surgery. About 30% of the interventions will re-narrow within a year due to restenosis and graft-stenosis. Thickening of the luminal layer, the intima, is an important component in these side-effects.

  4. 2. Mesenchymal heterogeneity in the adult human lung

    Author : Måns Kadefors; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lung; Extracellular matrix; Adventitia; Fibroblast; mesenchymal cell; Alveolar epithelial cell; Fibrosis; Idiopathic pulmonary fibrosis; Mass spectrometry; RNA-sequencing;

    Abstract : The human lung is a complex tissue consisting of a heterogeneous mix of different structures and cells, each which a specific role that together contribute to the primary function of the organ: the gas exchange. Different mesenchymal cells populate the interstitial areas around airways and blood vessels and form the connective tissue together with the extracellular matrix. READ MORE

    Author : Monika K Grudzinska; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cardiovascular disease is the leading cause of global mortality and physical disability mainly due to the complications such as myocardial infarction or stroke. Physiological healing reaction takes place in the diseased vessel wall aimed to repair the vessel after an injury. READ MORE

  6. 4. Hyaluronan and the receptor CD 44 in the heart and vessels : a study in normal and pathological conditions

    Author : Martin Hellström; Anna Engström-Laurent; Bengt Johansson; Lena Jonasson; Umeå universitet; []
    Keywords : hyaluronan; CD44; heart; Rat; cardiac hypertrophy; artery; vein; human; Medicine; medicin;

    Abstract : Tissues are not solely composed of cells. The extracellular matrix is important for the cell well-being and cell-cell communication. The glycosaminoglycan hyaluronan (HYA) is a widely distributed extracellular matrix (ECM) component. READ MORE

  7. 5. Harvesting of Saphenous Vein for Coronary Artery Bypass Grafting : An Improved Technique that Maintains Vein Wall Integrity and Provides a High Early Patency Rate

    Author : Domingos Souza; Kjell Rådegran; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Saphenous vein; coronary bypass; endothelium; nitric oxide; patency rate; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Abstract : The primary aim of this thesis was to modify saphenous vein (SV) harvesting technique and evaluate its clinical importance. A new "no touch" (NT) technique of SV preparation was developed where the vein is harvested with a pedicle of surrounding tissue, which protects the vein from spasm therefore obviating the need for distension.
