    Sammanfattning : In this thesis, we investigate different aspects of the class of Herglotz-Nevanlinna functions in several variables. These are holomorphic functions on the poly-upper half-plane having non-negative imaginary part. Our results are presented in the four research articles A1 - A4, which are included in this thesis.

  5. 9. 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 :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

  7. 10. Synthesis, characterization and molecular architecture of electroactive and degradable polymers
