  1. 16. Cloning and characterization of canine sulfotransferases

    Författare :Carrie Tsoi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sulfotransferase; dog; cytosol; cloning; catalytic properties; mutagenesis;

    Sammanfattning : Sulfation generally leads to an increase in hydrophilicity facilitating increased excretion of conjugated molecules. In addition, sulfation has an important role in the synthesis, metabolism and regulation of steroid hormones as well as in the generation of reactive electrophilic forms of mutagenic heterocyclic amines and hydroxymethyl polyaromatic hydrocarbons.

  3. 17. Heparan Sulfate Biosynthesis – Clues from Knockout Mice

    Författare :Johan Ledin; Lena Kjellén; John Gallagher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; heparan sulfate; biosynthesis; gene targeting; embryonic development; proteoglycans; NDST; N-deacetylase N-sulfotransferase; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : In the extracellular space, many specialized proteins are located to support cells and to mediate cell-cell signalling. One class of such molecules is heparan sulfate (HS) proteoglycans, which are proteins with different properties and locations but all of them decorated with long unbranched HS polysaccharide chains.

  4. 18. Study and Modeling of the Reduction of Sulfur Dioxide, Nitrogen Oxides and Hydrogen Chloride by Dry Injection Technologies

    Författare :Wuyin Wang; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reaction kinetics; pore particle size; HCl; NOx; desulfurization; Ca-based sorbent; flue gas; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : The potential and mechanism to reduce acid gases, such as SO2, NOx and HCl by dry Ca-based sorbents have been studied to improve the efficiencies of the process and sorbent utilization. Several natural limestones were tested for SO2 removal. Calcium conversion as high as 45% was achieved within 0.3 s at 1000°C, 1000 ppm SO2 and Ca/S=1. LÄS MER

  5. 19. Galactosaminoglycans - Role in Brittlestar Limb Regeneration

    Författare :Rashmi Ramachandra; Dorothe Spillmann; Barbara Mulloy; Uppsala universitet; []
    Nyckelord :Chondroitin sulfate; Dermatan sulfate; Brittlestar; Regeneration;

    Sammanfattning : Regeneration is, in simple terms, ‘to re-grow’ damaged or lost parts of the body (e.g. cells, tissues and organs) and is a natural phenomenon occurring throughout the life of an organism. The regenerative capacity varies in the animal kingdom. LÄS MER

  7. 20. Myofibroblasts and the Vascular Endothelium : Impact of Fibrin Degradation Products and miRNA on Vascular Motility and Function

    Författare :Peder Fredlund Fuchs; Pär Gerwins; Johan Kreuger; Arne Östman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Angiogenesis; Vascular biology; Chemotaxis; Endothelial cell; Myofibroblast; Wound healing; miRNA; Heparan sulfate; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Angiogenesis is the formation of new blood vessels from pre-existing vasculature and is important during development as well as wound healing and tissue remodeling. Angiogenesis also occurs during pathological conditions such as diabetic retinopathy and cancer. LÄS MER
