2. 1. Surface expression using the AIDA autotransporter : Towards live vaccines and whole-cell biocatalysis

   Author : Martin Gustavsson; Gen Larsson; Per Berglund; Andres Veide; Jan-Willem de Gier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AIDA-autotransporter; Escherichia coli; live vaccines; surface expression;

   Abstract : The area of surface expression has gathered a lot of interest from research groups all over the world and much work is performed in the area. Autotransporters have been used for surface expression in Gram-negative bacteria. READ MORE

   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

   Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

5. 3. Adsorption of surface active elements on the iron (100) surface : A study based on ab initio calculations

   Author : Weimin Cao; Seshadri Seetharaman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sulfur; oxygen; surface adsorption; iron surface; ab initio calculations; adsorption energy; work function; difference charge density; thermodynamic stability; average velocity; Materials science; Teknisk materialvetenskap;

   Abstract : In the present work, the structural, electronic properties, thermodynamic stability and adatom surface movements of oxygen and sulfur adsorption on the Fe surface were studied based on the ab initio method. Firstly, the oxygen adsorbed on the iron (100) surface is investigated at the three adsorption sites top, bridge and hollow sites, respectively. READ MORE

6. 4. Improved detection and performance of surface expression from the AIDA-I autotransporter

   Author : Johan Jarmander; Gen Larsson; Ulrika Rova; Ines Ezcurra; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface expression; autotransport; AIDA-I; Escherichia coli; proteolysis; detection tag;

   Abstract : Surface expression of recombinant proteins has attracted a lot of attention due to its potential in applications such as enzyme production, vaccine delivery and bioremediation. Autotransporters have been used for surface expression of a variety of proteins, but the expression systems reported in literature have typically been inflexible and incapable of detecting proteolysis, thereby limiting surface expression yield.

7. 5. Healing of endosseous implants with different surface characteristics in grafted and non-grafted bone : clinical and experimental studies

   Author : Måns Jungner; Stefan Lundgren; Malou Hultcrantz; Carina Lundqvist; Peter Nilsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental implants; surface characteristics; bone graft; maxillary sinus; implant survival; oxidized surface; turned surface; sinus membrane elevation; bone formation; macrophages; osteocalcin; osteopontin; CD68; odontologi; Odontology;

   Abstract : Aims: This study uses radiological and clinical evaluations of the healing of endosseous titanium implants presented with different surface characteristics in the clinical situation (paper I-III) and experimentally to describe the early bone healing in maxillary sinus membrane elevation with and without the use of grafting material (paper IV).Material and methods: In paper I, 136 patients were treated with 394 dental implants – 199 were oxidized titanium implants (Nobel Biocare TiUnite) and 195 were turned titanium surface implants (Nobel Biocare Mark III).
