2. 1. Decellularization as a method to generate a new generation of vascular grafts

   Author : Robin Simsa; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tissue engineering; vascular grafts; cardiovascular disease; decellularization;

   Abstract : Decellularization of blood vessels is a technique to remove cells from the extracellular matrix (ECM), which can be used as a vascular graft for peripheral or coronary blood vessel bypass surgery. This thesis focuses on the optimization of decellularization strategies for blood vessels such as porcine vena cava, to determine the optimal decellularization protocol (Paper I) and the ideal method of applying liquids during the decellularization process (Paper II).

4. 2. Thrombolysis in vascular surgery

   Author : Linn Smith; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background and aims: Thrombolysis is in common use in the treatment of acute forms of vascular disease. It may be used both systemically and locally, in the latter case through an endovascular approach, socalled catheter-directed thrombolysis. READ MORE

5. 3. 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

6. 4. Implantation-Site Dependent Differences in Engraftment and Function of Transplanted Pancreatic Islets

   Author : Joey Lau; Per-Ola Carlsson; Leif Jansson; Carina Carlsson; Caroline Kampf; Annika Tibell; Uppsala universitet; []
   Keywords : Cell biology; Type 1 diabetes; pancreatic islets; human islets; islet transplantation; vascular engraftment; revascularization; implantation-site; microenvironment; vascular density; insulin release; pro insulin biosynthesis; glucose oxidation; Cellbiologi;

   Abstract : Transplanting pancreatic islets into the liver through the portal vein is currently the most common procedure in clinical islet transplantations for treating patients with brittle type 1 diabetes. However, most islet grafts fail within a 5-year period necessitating retransplantation. READ MORE

7. 5. Cold finger

   Author : Clas Backman; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; vascular; microsurgery; replantation; Cold intolerance; Vasospa;

   Abstract : Post Traumatic Cold Intolerance is the most common, and often the most prominent disabilityfrom hand trauma. The discomfort caused by cold is believed to be linked to a dysfunction o f thedigital vasoregulation, but its pathophysiology is poorly understood. Cold induced vasospasm, i.e. READ MORE
