  1. 16. Studies on vascular remodeling in acute coronary artery disease

    Author : Fei Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Atherosclerosis; unstable angina; matrix metalloproteinase; apoptosis; angiogenesis; remodeling;

    Abstract : Atherosclerosis is an arterial disease, characterized by endothelial dysfunction, vascular inflammation, and lipid accumulation in the vessel wall. Unstable coronary syndroms may be initiated by rupture of the atherosclerotic plaque, which may be caused by activation of matrix metalloproteinases (MMPs), apoptosis and angiogenesis. READ MORE

  2. 17. The Microvasculature of Endogenous and Transplanted Pancreatic Islets : Blood Perfusion, Oxygenation and Islet Endocrine Function

    Author : Richard Olsson; Per-Ola Carlsson; Leif Jansson; Arne Andersson; Thomas Linn; Uppsala universitet; []
    Keywords : Cell biology; diabetes mellitus; pancreatic islets; islet transplantation; vascular engraftment; islet microcirculation; oxygenation; blood flow; protein biosynthesis; Cellbiologi;

    Abstract : Type 1 diabetes mellitus affects millions of people worldwide. Islet transplantation is a minimal invasive surgical procedure that restores euglycemia and halts the progression of diabetic complications. However, despite transplantation of islets from multiple donors most patients reverse to hyperglycemia within five years. READ MORE

  3. 18. Artificial blood vessels - Studies on endothelial cell and blood interactions with bacterial cellulose

    Author : Helen Fink; Göteborgs universitet; []
    Keywords : bacterial cellulose; endothelial cells; thrombogenicity; xyloglucan; contact activation; imaging of coagulation; vascular grafts; RGD; cell adhesion; bioreactor; xyloglucan;

    Abstract : Cardiovascular diseases are still the number one cause of death or invalidity in the western world today. Atherosclerotic plaques and restenosis can result in severe occlusions of peripheral and coronary arteries. Treatment depends on the severity of the disease and includes drug therapy and bypass surgery. READ MORE

  4. 19. Experimental Studies on the Vasculature of Endogenous and Transplanted Islets of Langerhans

    Author : Göran Mattsson; Leif Jansson; Alberto Hayek; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; islets of Langerhans; endothelial cells; islet transplantation; vascular density; diabetes mellitus; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Abstract : The blood vessels of the pancreatic islets are of crucial importance for oxygen and metabolite supply as well as dispersal of secreted hormones. In addition to this, endothelial cells have an important role in the revascularization process after islet transplantation. READ MORE

  5. 20. Mesenchymal stem cells in vascular structure and remodeling in cancer

    Author : Ewa Kurzejamska; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mesenchymal stem cells (MSCs) are present in vascular structure and play an important role in vessel remodeling in normal, as well as pathological conditions, such as transplant arteriosclerosis or tumor angiogenesis. Moreover, MSCs affect tumor growth and metastasis by production of chemokines, such as (C-C motif) ligand 7 (CCL7). READ MORE
