2. 11. Adhesion Dependent Signals : Cell Survival, Receptor Crosstalk and Mechanostimulation

   Author : Anjum Riaz; Staffan Johansson; Bengt Hallberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Integrins; Signal transduction; Protein kinase B; Akt; PI3K; Heparanase; ROS; Mechanosignalling; Molekylär cellbiologi; Molecular Cellbiology; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Cellforskning; Cell Research;

   Abstract : The integrin family of cell surface receptors is evolutionary conserved and found in all multicellular animals. In humans 8-alpha and 18-beta integrins are non-covalently associated into 24 dimers. Integrins mediate cell-extracellular matrix and cell-cell interactions and participate in cell signalling.

4. 12. Outcome and prevention strategies in peritoneal adhesion formation

   Author : Fanny Fredriksson; Helene Lilja; Bobby Tingstedt; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peritoneal adhesion prevention; inflammatory cytokines; experimental adhesion model; adhesive small bowel obstruction; adhesion-related morbidity; Barnkirurgi; Pediatric Surgery;

   Abstract : Peritoneal adhesions occur in up to 93% of adults after peritoneal trauma during surgery. Most adhesions are asymptomatic but can cause female infertility, small bowel obstruction (SBO) and chronic abdominal pain. Adhesion prophylaxis is needed to reduce the significant morbidity and increased health care costs resulting from peritoneal adhesions. READ MORE

5. 13. Adhesion to machined and laser ablated wood surfaces

   Author : Micael Stehr; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ablation; adhesion; checks; coating; cracks; excimer laser; gluing; IR laser; mechanical machining; mechanical weak boundary layer; microscopy; notched specimens; pine; planing; sample preparation; sawing; scanning electronmicroscopy; spruce; tip-cracks; UV laser; weak boundary layer; wood;

   Abstract : This thesis is a contribution to the R&D-program ValueActivation at KTH,Division of Wood Technology and Processingand containsfive papers related to the evaluation and development ofmachining techniques (mechanical and irradiation treatments)whereby weak boundaries at the wood surfaces in the form of(mechanical) weak boundary layers and (micro) cracks due tomechanical treatment can be avoided.The first paper describes the development of a method–using a UV laser–to study the mechanically weakenedboundaries.

6. 14. Adhesion in the wheel-rail contact under contaminated conditions

   Author : Yi Zhu; Ulf Olofsson; Ines Lopez Arteaga; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesion; wheel-rail contact; contaminants; rough surfaces;

   Abstract : Railway vehicles require a certain level of adhesion between wheel and rail to operate efficiently, reliably, and economically. Different levels of adhesion are needed depending on the vehicle running conditions. READ MORE

7. 15. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria

   Author : Mirva Drobni; Nicklas Strömberg; Karl-Eric Magnusson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biofilm; Actinomyces; Streptococcus; adhesion; Cariology; Cariologi;

   Abstract : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. READ MORE
