  1. 21. Effect of the tri-peptide glycyl-prolyl-glycine amide on HIV-1 replication

    Författare :Jin Su; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV-1; antiretrovirals; peptides; tri-peptides; GPG-NH2; capsid formation; p24 dimerization; coneshaped core; GPG motif; V3 loop; infectivity;

    Sammanfattning : The human immunodeficiency virus type 1 (HIV-1) is the etiological agent responsible for AIDS worldwide. The aim of this thesis was to evaluate the anti-HIV-1 activity of short peptides and to investigate their mode of inhibition. LÄS MER

  3. 22. Studies of the device perfect capsule in an animal model to reduce lens epithelial cell proliferation

    Författare :Mahmoud Taie Abdelwahab; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The sealed-capsule irrigation device, the Perfect Capsule, is a surgical device designed to target lens epithelial cells (LECs) during cataract surgery and prevent posterior capsule opacification (PCO). This is especially important in cases in which the posterior capsule must stay intact after cataract surgery, such as when implanting accommodative lenses. LÄS MER

  4. 23. Macrophage-material surface interactions

    Författare :Christina Gretzer; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

    Sammanfattning : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. LÄS MER

  5. 24. Lipid-Based Surface Modifications: towards the Development of Membrane-Protein Arrays

    Författare :Indriati Pfeiffer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA-array; cholesterol-DNA; EIS; membrane proteins; lipid vesicles; QCM-D; supported lipid bilayer;

    Sammanfattning : Mimics of the natural cell membrane, such as lipid vesicles and supported lipid membranes, have gained significant attention in recent years. This is primarily due to their ability to provide scientists with a model system allowing a large arsenal of scientific tools to be used in studies of biological reactions that are naturally controlled by the cell membrane and its components.

  7. 25. Engineered core-shell nanoparticles for biomedical applications

    Författare :Carmen Mihaela Vogt; Mamoun Muhammed; Alfonso Garcia-Bennett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Functional materials; Funktionella material;

    Sammanfattning : The necessity for synthesis of nanoparticles with well controlled size and morphology emerged with the development in recent years of novel advanced applications especially in biomedical related fields. These applications require nanoparticles with more complex architecture such as multifunctional nanoparticles (i.e. LÄS MER
