16. Long time follow up of implant therapy and treatment of peri-implantitis
Sammanfattning : POPULÄRVETENSKAPLIG SAMMANSTÄLLNINGDentala implantat har blivit ett ofta använt alternativ för att ersätta förlorade tänder, vilket resulterat i att en ökad andel av den vuxna befolkningen är försedd med implantatförankrad protetik. Trots attfördelaktiga långtidsresultat av implantatbehandling rapporteratsförekommer infektioner. LÄS MER
17. Biophysical Studies of Apolipoprotein A-IM and a Partitioning study
Sammanfattning : The major part of this thesis deals with the similarities and differences in some biophysical properties of apolipoprotein A-I (apo A-I) and the molecular variant apolipoprotein A-IMilano (apo A-IM), and the influence on lipid binding. A model compound partitioning study has also been performed. LÄS MER
18. Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells
Sammanfattning : Type-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. LÄS MER
19. Recombinant spider silk for biomedical applications - from functionalizing surfaces of synthetic materials to in vitro modelling of tissues
Sammanfattning : Spider silk is a natural protein-based material known for its medicinal use and remarkable mechanical properties. Structures made thereof are both strong and elastic and have been shown to be favorable matrices for tissue engineering. LÄS MER
20. Simulations of Transport Phenomena and Porous Structures Using Dissipative Particle Dynamics
Sammanfattning : The topic of this work is simulations of porous materials and transport phenomena at a mesoscopic length scale, i.e., a length scale larger than an individual atom but smaller than the continuum. The porous material studied is a membrane used in fuel cells. LÄS MER
