  1. 1. Semipermeable membrane devices as integrative tools for monitoring nonpolar aromatic compounds in air

    Detta är en avhandling från Umeå : Kemi

    Författare :Hanna Söderström; Umeå universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; air pollution; alkyl-PAHs; atmosphere; bioavailability; boundary layer; diffusive sampling; emissions; integrative; membrane; monitoring; nitro-PAHs; PAHs; particles; passive samplers; PCBs; plants; PRCs; release rate; sampler design; sources; SPMDs; traffic; uptake rate; wind effect; wood burning; Miljökemi; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Sammanfattning : Air pollutants pose a high risk for humans, and the environment, and this pollution is one of the major environmental problems facing modern society. Active air sampling is the technique that has been traditionally used to monitor nonpolar aromatic air pollutants. LÄS MER

  2. 2. Membrane traffic in neutrophils and neutrophil-like cells

    Detta är en avhandling från Department of Clinical Sciences, Lund University

    Författare :Susanne Bauer; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; membrane traffic; Hematologi; extracellular fluids; Haematology; Medicin människa och djur ; Medicine human and vertebrates ; CD177; extracellulära vätskor; PR3; phagocytosis; Streptococcus pyogenes; Infektioner; neutrophils;

    Sammanfattning : The neutrophil constitutes the first line of defence against invading organisms and its primary function is to recognize, phagocytose and kill intruding microorganisms. In this thesis, the membrane traffic in neutrophils and neutrophil-like cells was studied. Non-opsonised S. LÄS MER

  3. 3. Phagocytosis by neutrophils - studies on phagosome dynamics and membrane traffic modulation by Streptococcus pyogenes

    Detta är en avhandling från Lund University

    Författare :Pontus Nordenfelt; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fluorescence microscopy; membrane traffic; neutrophil; Streptococcus pyogenes; phagosome; phagocytosis;

    Sammanfattning : Neutrophils are our most numerous and deadly white blood cells and without them we would succumb quickly to infections by pathogens. The main mechanism that the neutrophils employ for our protection is phagocytosis, where they eat and enclose their target inside a membrane-bound organelle, the phagosome. LÄS MER

  4. 4. Property-controlling Enzymes at the Membrane Interface

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Changrong Ge; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monotopic membrane protein; lipid-protein interaction; membrane curvature; glycosyltransferase; Rossmann fold; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Sammanfattning : Monotopic proteins represent a specialized group of membrane proteins in that they are engaged in biochemical events taking place at the membrane interface. In particular, the monotopic lipid-synthesizing enzymes are able to synthesize amphiphilic lipid products by catalyzing two biochemically distinct molecules (substrates) at the membrane interface.

  5. 5. Strategies to explore the membrane proteome of a cell

    Detta är en avhandling från Stockholm : Department of Analytical Chemistry, Stockholm University

    Författare :Gianluca Maddalo; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteomics; Escherichia coli; Enterococcus faecalis; Synechocystis; Mass Spectrometry; BN SDS-PAGE; FT-ICR-MS; Myelin P2 protein; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : The cell envelope plays key roles in numerous processes such as maintaining cellular integrity, communication with other cells, signal transduction, maintenance of cellular homeostasis, and regulation of the traffic of molecules between the cell and the extracellular milieu. Essential membrane components in many of these processes are proteins. LÄS MER
