  1. 16. Long time follow up of implant therapy and treatment of peri-implantitis

    Författare :Ann‐Marie Roos‐Jansåker; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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

  3. 17. Biophysical Studies of Apolipoprotein A-IM and a Partitioning study

    Författare :Malin Suurkuusk; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apolipoprotein A-IMilano; Apolipoprotein A-I; Lipoprotein; Lipid; Microcalorimetry; DCS; Denaturation; Guanidine Hydrochloride; Physics; Fysik; Chemistry; Kemi;

    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

  4. 18. Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells

    Författare :Xiaosong Ma; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrinology; secreting systems; type-2 diabetes; SUR1; Ca2 -channel; glucagon; exocytosis; insulin; diabetology; Endokrinologi; sekretion; diabetologi;

    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

  5. 19. Recombinant spider silk for biomedical applications - from functionalizing surfaces of synthetic materials to in vitro modelling of tissues

    Författare :Christos Panagiotis Tasiopoulos; My Hedhammar; Antonella Motta; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; recombinant spider silk; surface functionalization; in vitro tissue models; membrane-based models; barrier tissues; cell co-culture; tissue engineering; Bioteknologi; Biotechnology;

    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

  7. 20. Simulations of Transport Phenomena and Porous Structures Using Dissipative Particle Dynamics

    Författare :Erik Johansson; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    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
