  1. 1. Synthesis, Characterisation and Properties of Biomimetic Biodegradable Polymers

    Författare :Fredrik Nederberg; Tim Bowden; Nicola Tirelli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; biodegradable polymers; biomimetic; phospholipid-like; phosphorylcholine; amphiphilic; ionomer; hemocompatible; non-adhesive; water uptake; reduced protein adsorption; protein delivery; Kemi; Chemistry; Kemi;

    Sammanfattning : The acceptance of blood contacting implants creating favorable conditions in vivo is decisively determined by their interaction with proteins that mediate inter cellular interactions with synthetic substrates. Adsorbed proteins can activate blood cascade systems like coagulation and complement that may result in serious blood clots, and/or immunological reactions. LÄS MER

  3. 2. Surface Modifications for Biointerfaces - Supported Lipid Bilayers and some Aspects of Microcontact Printing

    Författare :Karin Glasmästar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QCM-D; PDMS; cell attachment; supported lipid bilayer; microcontact printing; SPR; ToF-SIMS; protein adsorption; formation kinetics; XPS;

    Sammanfattning : Biointerfaces engage several disciplines: physics, materials science, chemistry, biology and medicine. They are found on the surfaces of implants, tubes and tanks in the food industry or on the hull of a boat. In this work, model surfaces aimed for contact with biological systems were studied.

    Sammanfattning : Nanocellulosa, som kan utvinnas från skogsråvara, har de senaste åren fått mycket uppmärksamhet för sina intressanta egenskaper och breda användningsområde. Studierna i denna avhandling syftar till att vidga möjligheterna att använda nanocellulosa i olika applikationer. LÄS MER

  5. 4. Modulation of the deubiquitinating system in viral infection, lymphoid cell activation and malignant transformation

    Författare :Ulrika Rolén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Most cellular proteins are affected by the conjugation of Ubiquitin (Ub), which may regulate their stability, activity or localization. The family of deubiquitinating enzymes (DUBs) removes Ub from conjugates and regulates the production and recycling of Ub. LÄS MER
