  1. 1. Synthesis of functional degradable polymers by radical ring-opening polymerization

    Författare :Jenny Undin; Ann-Christine Albertsson; Mats Johansson; Monica Ek; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; tissue engineering; ring-opening polymerization; 2; 2´-azoisobutyronitrile; cyclic ketene acetals; 2-methylene- 1; 3; 6-trioxocane; 2-methylene- 1; 3-dioxepane; vinyl acetate; coopolymerization;

    Sammanfattning : The increased demand for understanding cell-material interactions and subsequently create personalized implants for tissue engineering has resulted in an increased interest in developing new monomers with functional groups. The focus of the work presented in this thesis has been on the synthesis of functional monomers and the polymerization of these into functional amorphous aliphatic polyesters. LÄS MER

  3. 2. In Vitro Studies of the Substrate Specificities of Heparan Sulfate 2-O- and 6-O-sulfotransferases

    Författare :Emanuel Smeds; Marion Kusche-Gullberg; Ulf Lindahl; Catherine L. R. Merry; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; heparin; sulfotransferase; 2-O-sulfotransferase; 6-O-sulfotransferase; polysaccharide biosynthesis; glycosaminoglycan; O-sulfotransferase; proteoglycan; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Heparan sulfate (HS), a linear negatively charged polysaccharide located at the cell surface and in the extracellular matrix, interacts with, and thereby regulates the functions of numerous proteins. HS-protein interactions depend on the fine structure of HS, especially its sulfation pattern. LÄS MER

  4. 3. Skuggan av ett leende : om filmisk ironi och den ironiska berättelsen

    Författare :Örjan Roth-Lindberg; Stockholms universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Ironi; Film; Berättarkonst;

    Sammanfattning : In Shadow of a Smile the discourse of irony is brought to a new Field: irony as visual narrative devices and as interactions of verbal and visual elements in film and TV structures. The discussion, which puts forward several new definitions, is based throughout on examples from a central core of cinematic material, e.g. LÄS MER

  7. 5. Novel Rearrangements of Vinylaziridines: Aza-[2,3]-Wittig Rearrangements and [1,5]-Hydrogen Shifts

    Författare :Jens Åhman; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 6-tetrahydropyridines; 3; 2; substituted 1; indolizidine alkaloid synthesis; 5]-hydrogen shift; homodienyl-[1; 3]-Wittig rearrangement; vinylaziridine synthesis; aza-[2; N-alkylation of aziridines; allylic imines; 1-pyrrolines.; Organic chemistry; Organisk kemi;

    Sammanfattning : A route from epoxy alcohols to cis- and trans-trisubstituted vinylaziridines has been developed. The vinylaziridines have been used as substrates in the base induced aza-[2,3]-Wittig rearrangement to substituted 1,2,3,6-tetrahydropyridines. LÄS MER
