1. 6. Fucoidan-Mimetic Glycopolymers : Synthesis and Biomedical Applications

   Författare :Mattias Tengdelius; Peter Konradsson; May Griffith; Peter Påhlsson; Mats Johansson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The marine polysaccharide fucoidan has demonstrated several interesting biological properties, for instance being antiviral, anticoagulant, anti-inflammatory, anticancer, and platelet activating. Many of these properties are desirable for various biomedical applications. Yet, there are few reports on fucoidan being used in such applications. LÄS MER

3. 7. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

   Författare :Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

   Sammanfattning : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

4. 8. Enzyme Hydrolysis of Cellulose Derivatives. Active Site Studies and Polymer Characterisation

   Författare :Herje Schagerlöf; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Humicola insolens; Trichoderma reesei; Bacillus agaradhaerens; Mass spectrometry; Substituent distribution; Characterisation; Endoglucanases; Cellulose derivatives;

   Sammanfattning : Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. LÄS MER

5. 9. Structure and lipid interactions of membrane-associated glycosyltransferases : Cationic patches and anionic lipids regulate biomembrane binding of both GT-A and GT-B enzymes

   Författare :Scarlett Szpryngiel; Lena Mäler; Marcelo Guerins; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycosyltransferase; monotopic membrane proteins; galactolipids; NMR; chitin synthase; DGD2; LPS; WaaG; MIT domain; Biophysics; biofysik;

   Sammanfattning : This thesis concerns work on structure and membrane interactions of enzymes involved in lipid synthesis, biomembrane and cell wall regulation and cell defense processes. These proteins, known as glycosyltransferases (GTs), are involved in the transfer of sugar moieties from nucleotide sugars to lipids or chitin polymers. LÄS MER

7. 10. Enzymatic Synthesis of Functional Polyesters

   Författare :Mohamad Takwa; Karl Hult; Pål Nyren; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

   Sammanfattning : Enzymes are successfully employed in the synthesis of different types of polymers. Candida antarctica lipase B is a highly efficient catalyst for the synthesis of polyesters by ring opening polymerization. ω-Pentadecalactone is an interesting lactone due to the unique proprieties of its polymer (poly-pentadecalactone).
