  1. 11. Reaction and Diffusion Phenomena in Biomimetic Nanoscale Reactors and Networks

    Author : Kristin Sott; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial cell; restricted geometries.; enzymatic reactions; micromanipulation; biomimetic; nanotubes; diffusion; Vesicles; networks; liposomes;

    Abstract : Methods for construction of geometrically complex, fully connected surface-immobilized microscopic networks of phospholipid bilayer vesicles (1-50 µm in diameter) interconnected by lipid nanotubes (100-300 nm in diameter), have been developed. The networks have controlled connectivity and are well-defined with regard to the container size, content, angle between nanotube extensions, and nanotube length. READ MORE

  2. 12. Lipid Self-Assembly and Lipase Action

    University dissertation from Johanna Borné, Sofia Parken 5B, 222 42 Lund

    Author : Johanna Borné; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; specific activity.; Physical chemistry; Fysikalisk kemi; vesicles; cubosomes; liquid crystalline phases; sodium oleate; oleic acid; diolein; monoolein; Oleic acid based acyl glycerols; Thermomyces lanuginosa lipase;

    Abstract : In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic acid (OA), sodium oleate (NaO) and glycerol .

  3. 13. The release of histone proteins from cells via extracellular vesicles

    University dissertation from Umeå : Umeå University

    Author : Uma Muthukrishnan; Jonathan Gilthorpe; Miles Trupp; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Histone; extracellular vesicles; exosomes; extracellular histones extracellular DNA; cellular stress; proteomics; ESCRT complex; Lrrn1; mid-hindbrain organizer; ovarian cancer; ascites;

    Abstract : Histones are chromatin-associated proteins localized to the nucleus. However, extracellular histones are present in biofluids from healthy individuals and become elevated under disease conditions, such as neurodegeneration and cancer. READ MORE

  4. 14. Therapeutic potential of extracellular vesicles

    University dissertation from Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Author : Oscar Wiklander; Karolinska Institutet.; Karolinska Institutet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Extracellular vesicles (EVs) are nanometer-sized, lipid membrane enclosed, vesicles that are secreted by most, if not all, cells and contain macromolecular material of the source cell including lipids, proteins and various nucleic acid species. Over the last two decades, EVs have been recognized as important mediators of cell-to-cell communication that influence both physiological and pathological conditions. READ MORE

  5. 15. Association and Microstructure in Self-Assembling Catanionic Systems

    University dissertation from Physical Chemistry 1, Lund University

    Author : Eduardo Marques; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFG NMR self-diffusion; cryogenic-transmission electron microscopy; catanionic systems; gels; bile salts; polyelectrolytes; liquid crystals; vesicles; Surfactants; phase diagrams; light microscopy; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : This thesis addresses the phase behavior and phase structure in mixed surfactant-surfactant and surfactant-polymer systems, where the co-solutes have opposite charges (catanionic systems). The initial goal has been to investigate self-assembly aspects in mixtures of single-/double-chained surfactants and bile salt/double-chained surfactants, with the main focus on vesicle assembly in dilute regions.
