1. 1. Formation of Composite Islet Grafts : A novel strategy to promote islet survival and revascularization

   Författare :Ulrika Johansson; Peetra Magnusson; Korsgren Olle; Bo Nilsson; Federico Bertuzzi; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet of Langerhans; cytokines and cytokinereceptors expression; endothelial cells; mesenchymal stromal cells; transplantation; revascularization; Clinical immunology; Klinisk immunologi; cellforskning; cellforskning;

   Sammanfattning : The islets of Langerhans are small and delicate spheroid organs scattered in the pancreas responsible for insulin production. Transplantation of isolated islets is a beneficial therapy for patients with a severe form of type 1 diabetes. LÄS MER

4. 3. Survival of onlay bone grafts. A study in the adult rat

   Författare :Monica Gordh; Lunds universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

   Sammanfattning : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

5. 4. Decellularization as a method to generate a new generation of vascular grafts

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

   Sammanfattning : 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).

7. 5. On costochondral grafts replacing mandibular condyles in juvenile chronic arthritis. A clinical, histological and experimental study

   Författare :Börje Svensson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; juvenile chronic arthritis; temporomandibular joints; temporomandibular disorders; costochondral grafts; growth; revascularisation; microangiography; fluorochrome labelling.;

   Sammanfattning : In children with juvenile chronic arthritis (JCA), disturbances of mandibular growth and function may result in involvement of the temporomandibular joints (TMJs). The aim of this thesis was to study the stomatognathic system in JCA children and long-term effects on facial growth of treatment comprising replacement of arthritic mandibular condyles with autogenous costochondral grafts (CCGs) during growth.
