  1. 21. Helicobacter pylori cell surface interactions with glycosaminoglycans. Identification and characterisation of proteins binding to heparin/heparan sulphate

    Författare :Meeme Utt; Celiaki och diabetes; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SELDI-TOF MS; bioinformatics; proteomics; immunoblotting; 2-DE; biosensor; heparan sulphate; heparin; binding; Helicobacter pylori; cell surface; bakteriologi; Mikrobiologi; mycology; bacteriology; Microbiology; mykologi; virologi; virology;

    Sammanfattning : Helicobacter pylori is a gastric pathogen which cause chronic type B gastritis and peptic ulcer disease. H. pylori produces virulence factors such as urease, vacuolating cytotoxin VacA, cag pathogenicity island-associated proteins, flagella and adhesins. LÄS MER

  3. 22. Characterizing Chromatography Media : NMR-based Approaches

    Författare :Fredrik Elwinger; István Furó; Stéphane Viel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatography; nuclear magnetic resonance; NMR; self-diffusion; magic-angle spinning; quantitative; distribution coefficient; pore size; Kemi; Chemistry;

    Sammanfattning : Liquid chromatography is an essential technique in manufacturing biopharmaceuticals where it is used on all scales from analytical applications in R&D to full-scale production. In chromatography the target molecule, typically a protein, is separated and purified from other components and contaminants. LÄS MER

  4. 23. Recognition molecules of the complement system: C1q and mannan-binding lectin in autoimmunity and immune defence

    Författare :Ulla Mårtensson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; serologi; Immunologi; Immunology; serology; autoantibodies; collectins; complement; autoimmunity; Infections; Infektioner;

    Sammanfattning : The C1 subcomponent C1q and the mannan-binding lectin (MBL) are recognition proteins of the complement system, and have similar structure. C1q binds to IgG and IgM and activates the classical pathway. MBL binds to carbohydrate structures and activates the lectin pathway. LÄS MER

  5. 24. Double-contrast MRI for the staging of rectal carcinoma: Technical aspects and clinical experience

    Författare :Nils-Olof Wallengren; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; Double contrast; MR imaging; Preoperative staging; Rectal carcinoma; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Aim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. LÄS MER

  7. 25. Phosphatidylethanol - formation and degradation in blood and organs

    Författare :Steina Aradottir; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostik; Public health; Diagnostics; organs; blood; HPLC; in vitro; in vivo; human; rat; phosphatidylethanol; phospholipase D; alcohol; ethanol; epidemiology; Folkhälsa; epidemiologi;

    Sammanfattning : Phosphatidylethanol (PEth) is an abnormal phospholipid formed exclusively by the action of phospholipase D (PLD) in the presence of ethanol. The degradation of PEth is slow and due to its accumulation in some cells the possibility to use PEth as marker of ethanol intake has been proposed. LÄS MER
