  1. 6. Templating and self-assembly of biomimetic materials

    Författare :Christian Mille; Lennart Bergström; Mika Linden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomimetic; biotemplating; self-assembly; triply periodic minimal surfaces; the gyroid; photonic crystals; band gap; structural color; chirality; butterflies; membrane proteins; lipid bilayers; sol-gel; mesostructured; polyhedral nanofoams; Materials Chemistry; materialkemi;

    Sammanfattning : This thesis focuses on the use of biomolecular assemblies for creating materials with novel properties. Several aspects of biomimetic materials have been investigated, from fundamental studies on membrane shaping molecules to the integration of biomolecules with inorganic materials. LÄS MER

  3. 7. ADAMTS13 phenotype in health and disease with special reference to thrombotic thrombocytopenic purpura

    Författare :Minola Manea Hedström; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urology; tubular cells; podocytes; kidney; plasma; ADAMTS13; thrombotic thrombocytopenic purpura; nephrology; Urologi; nefrologi; Pediatrics; Pediatri;

    Sammanfattning : Von Willebrand factor (VWF) is synthesized and secreted by endothelial cells into the plasma as a series of multimers. VWF induces the formation of platelet plugs at sites of vascular injury and high shear stress. Biological activity is dependent on multimeric size, which is regulated in plasma by the VWF-cleaving protease ADAMTS13. LÄS MER

  4. 8. Genetic dissection of tubulogenesis in the Drosophila trachea

    Författare :Johanna Hemphälä; Christos Samakovlis; Reinhard Schuh; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila; trachea; transposon mutagenesis screen; fusion; Dpp; Delta; tubular dimensions; Grainyhead; Krotzkopf verkehrt; intralumenal matrix; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : The formation of branched tubular organs, such as the mammalian lung kidney and vascular system, is an essential process in animal development. The Drosophila tracheal (respiratory) system provides a genetic model system to study the highly ordered process of branch outgrowth and fusion required to form continuous tubular networks. LÄS MER

  5. 9. Lipid Nanotubes as a Model for Highly Curved Cellular Membrane Structures

    Författare :Natalia Stepanyants; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cells and their organelles show a variety of membrane morphologies with multiplesubmicrometer features, for example, tubules, vesicles, folds and pores. The shape of thecellular membranes can dynamically change to support a variety of functions, such as cargotransport, transmission of signals between the cells, cell movement and division. LÄS MER

  7. 10. The role of catecholamines in regulation of renal tubular sodium transport

    Författare :Ulla Holtbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :sodium balance; Na ; H -antiporter; Na ; K -ATPase; renal proximaltubules; hormonal regulation.;

    Sammanfattning : Renal sodium metabolism, a major determinant of arterial blood pressure, is regulated with remarkable precision by a variety of endocrine, autocrine and neuronal factors. All these factors are known to regulate sodium metabolism by affecting the rate of renal tubular sodium reabsorption. LÄS MER
