  1. 1. Finite Element Simulations of Biphasic Articular Cartilages With Localized Metal Implants

    Författare :Krishnagoud Manda; Anders Eriksson; Ingrid Svensson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; knee joint; metal implant; poroelastic; biphasic; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Articular cartilage is a specialized connective soft tissue that resides onthe ends of long-bones, transfers the load smoothly between the bones in diarthrodialjoints by providing almost frictionless, wear resistant sliding surfacesduring joint articulation. Focal chondral or osteochondral defects in articularcartilage are common and show limited capacity for biological repair. LÄS MER

  3. 2. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application

    Författare :Torsten Malmström; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enantioselective; SAP; hydrogenation; hydroformylation; catalysis; biphasic; rhodium; poly-ethylene imine; poly-acrylic acid; polymers; water-soluble; phosphines; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. LÄS MER

  4. 3. Mechanics and Growth of Articular Cartilage Around a Localized Metal Implant

    Författare :Krishnagoud Manda; Anders Eriksson; Nico Verdonschot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; growth; knee; focal knee resurfacing; metal implant; poroelastic; porohyperelastic; biphasic;

    Sammanfattning : Articular cartilage is a specialized connective soft tissue that resides on the ends of long-bones, and transfers the load smoothly between the bones in diarthrodial joints by providing almost frictionless, wear resistant sliding surfaces during joint articulation.

  5. 4. Molecular mechanisms of biphasic insulin secretion

    Författare :Nikhil R. Gandasi; Sebastian Barg; Christien Merrifield; Uppsala universitet; []
    Nyckelord :Exocytosis; Insulin secretion; Membrane trafficking; Microscopy; Diabetes; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Pancreatic beta-cells secrete insulin in response to increase in blood glucose concentration with a rapid first phase and slower, sustained second phase. This secretion pattern is similar in entire pancreas, isolated islets of Langerhans and single beta-cells and it is disrupted in type 2-diabetes. LÄS MER

  7. 5. An injectable biphasic bone substitute in sinus augmentation

    Författare :Anna Truedsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dentala implantat; Dental Implants; Bone transplantation; Bone substitutes;

    Sammanfattning : This thesis concerns a new synthetic, injectable bone substitute, Cerament™, primarily developed for treatment of vertebral fractures. The purpose of the thesis was to investigate the properties of the newbone substitute, that is, whether it can contribute to the generation of new bone formation needed for placement of future dental implants.
