  1. 11. The release of histone proteins from cells via extracellular vesicles

    University dissertation from Umeå : Umeå University

    Author : Uma Muthukrishnan; Umeå universitet.; [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

  2. 12. Intracellular vesicles induced by monotopic membrane protein in Escherichia coli

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Hanna M. Eriksson; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; intracellular vesicles; Escherichia coli; glycosyltransferase; overexpression; optimization; detergent; screening; lipid composition; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : The monotopic membrane protein alMGS, a glycosyltransferase catalyzing glucolipid synthesis in Acholeplasma laidlawii, was overexpressed in Escherichia coli. Optimization of basic growth parameters was performed, and a novel method for detergent and buffer screening using a small size-exclusion chromatography was developed. READ MORE

  3. 13. 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

  4. 14. Association and Microstructure in Self-Assembling Catanionic Systems

    University dissertation from Physical Chemistry 1, Lund University

    Author : Eduardo Marques; Lund University.; Lunds universitet.; [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.

  5. 15. Diffusion in cationic vesicle and micellar solutions- a NMR study

    University dissertation from Physical Chemistry 1, Lund University

    Author : Cecilia Groth; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vesicles; Stopped-flow; micellar kinetics; water transport; DSC; Gemini surfactant; permeability; NOESY; Cationic surfactant; NMR diffusometry; extrusion;

    Abstract : Double tailed cationic surfactants are the active component in softeners. In the beginning of the 90s the active component in softener formulations was changed from a hydrolytically stable dialkyl dimethyl ammonium chloride (dialkyl quat) to a cleavable and biodegradable product containing ester groups in the alkyl chains (dialkyl ester quat).
