  1. 6. NK cell inhibitory receptor interactions with MHC class I molecules

    Författare :Jonas Sundbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NK cells; MHC class I molecules; inhibitory receptors;

    Sammanfattning : Natural killer (NK) cells represent the third population of lymphocytes in size after B- and T-cells. NK mediated killing of target cells is strongly influenced by MHC class I molecules expressed on target cells. In contrast to T-cells, NK cells can be inhibited by MHC class I molecules through the action of specific inhibitory NK cell receptors. LÄS MER

  3. 7. Size matters : RNA silencing processes in Phytophthora infestans

    Författare :Anna Åsman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Non-coding RNAs do not encode proteins but instead function through their own RNA sequence. These molecules range from several thousands of nucleotides (nt) in length down to around 20 nt. Specifically, small RNAs (sRNAs) have critical functions in eukaryotic cells, despite being only 20-30 nt long. LÄS MER

  4. 8. Hydrodynamic flow for deterministic sorting of cell-membrane components

    Författare :Björn Johansson Fast; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; Diffusion; Microfluidics; Native membrane vesicles; Single particle tracking; Protein enrichment; Hydrodynamic forces; Supported lipid bilayer; Size determination;

    Sammanfattning : The biological membrane, an amphiphilic structure that is the barrier between the cell interior and exterior, is one of the vital building blocks of all cells. Not only does it define the outer boundaries of the cell, it also carries important biological function by virtue of the proteins and other molecules that constitute the membrane, the function of which is in turn intimately coupled to their association with the lipid-based membrane.

  5. 9. Emulsification of Alkyl Ketene Dimer (AKD) -characterization of dispersions and emulsifiers

    Författare :Kristina Mohlin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrolysis; droplet size; hydrophobizing agent; dispersion; surfactant; AKD; emulsification; viscosity; surface tension; polymer; phase behavior; Alkyl Ketene Dimer;

    Sammanfattning : Alkyl Ketene Dimer (AKD) is a commonly used hydrophobizing agent in the paper industry, introducing capillary absorption barriers for polar liquids, which makes the paper more resistant to liquid penetration. Since AKD is a so-called internal sizing agent it is usually added in the form of a water-borne dispersion. LÄS MER

  7. 10. Preterm Infants - Odontological Aspects

    Författare :Marianne Rythén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm infants; adolescent; oral hygiene; gingivitis; dental caries; dental enamel; malocclussion; dental arch; tooth size; enamel hypomineralization; dentine; polarized light microscopy; X-ray microanalysis;

    Sammanfattning : ABSTRACT Preterm birth is associated with medical complications and treatments postnatally and disturbances in growth and development. Primary and permanent teeth develop during this postnatal period. LÄS MER
