  1. 16. Microglia : health promoting pathways and therapeutic targets in ageing and neuroinflammation

    Författare :Rasmus Berglund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Microglia are the innate immune cells of the CNS with an embryonic origin and self-renew with a slow turnover throughout life. The health-promoting capacities of this cell are being acknowledged through updated and specific tools separating microglia from bone marrow-derived macrophages. LÄS MER

  3. 17. Materials prepared using graphite oxides : properties and applications

    Författare :Artem Iakunkov; Aleksandr V. Talyzin; Josef Breu; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Graphene oxide; Activated Graphene; Swelling; Supercapacitor; Sorption of radionuclides; Materials Science; materialvetenskap; fysik; Physics;

    Sammanfattning : Graphite oxides are hydrophilic materials, which have attracted a lot of attention due to unique properties and possible applications. The current thesis includes studies of fundamental properties and applications of graphite oxides as well as materials prepared from graphite oxides such as graphene oxide membranes, defect-rich graphite oxide, reduced graphene oxide and activated reduced graphene oxide.

  4. 18. The effect of Gal alpha(1,3)gal glycopeptide-conjugates and human serum on HIV-1 infection and replication

    Författare :Maria Fernanda Perdomo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The first step in the entry of HIV-1 is the binding of the viral envelope glycoprotein (gp120) to the CD4 molecule expressed mainly on T helper cells. Upon binding, gp120 undergoes a series of conformational changes that expose inner epitopes, which in turn facilitate binding to the viral co-receptors (CCR5 or CXCR4). LÄS MER

  5. 19. Tethered Lipid Vesicles as Nanoscale Sensor Elements

    Författare :Seyed Tabaei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aquaglyceroporin; lipid vesicles; total internal reflection fluorescence TIRF microscopy; cell membrane; aquaporin; pore formation; surface plasmon resonance SPR ; phospholipase A2; antiviral peptide; lipid bilayer; biosensing; microfluidics;

    Sammanfattning : The primary aim of this thesis work has been to explore and advance the potential of surface tethered lipid vesicles as a platform for studying in particular the following three biomembrane-related processes: trans-membrane transport, membrane-peptide interactions and the activity of membrane active enzymes. First, a method based on surface plasmon resonance (SPR) spectroscopy was developed for studying passive diffusion processes as well as the membrane-protein mediated transport of small non electrolyte molecules across lipid bilayers.
