  1. 16. Structural and Conformational Analysis of Bacterial Polysaccharides using NMR Spectroscopy

    Författare :Axel Furevi; Göran Widmalm; Corine Sandström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates is one of the three classes of biomolecules found in nature. It is the most common one in comparison to the other two classes, lipids and proteins. However, this simple categorization does not reflect the reality since carbohydrates often are covalently linked to e.g. LÄS MER

  3. 17. Structure Elucidations of Bacterial Polysaccharides using NMR Spectroscopy and Bioinformatics

    Författare :Jonas Ståhle; Göran Widmalm; Evgeny Vinogradov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Bioinformatics; NMR Spectroscopy; Lipopolysaccharide; Glycosyltransferase; Computer-Assisted Structure Elucidation; O-antigen; Biosynthesis; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates are ubiquitous components in nature involved in a range of tasks. They cover every cell and contribute both structural stability as well as identity. Lipopolysaccharides are the outermost exposed part of the bacterial cell wall and the primary target for host-pathogen recognition. LÄS MER

  4. 18. Initiation of Innate Immune Responses in the Freshwater Crayfish Pacifastacus leniusculus

    Författare :Lee So Young; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; pattern recognition protein; innate immunity; crayfish; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk mykologi; Physiological Mycology;

    Sammanfattning : Prophenoloxidase (proPO) is a key enzyme for generation of melanin and is activated by the proPO activating enzyme (ppA) to its active form, PO. The active ppA was purified and cloned from crayfish hemocytes and it is a typical serine proteinase containing a clip, a proline-rich, and a glycine-rich domain. LÄS MER

  5. 19. Effects of Inflammatory Mediators on Pulmonary Airways

    Författare :Ofir Bachar; Klinisk och experimentell allergiforskning; []

    Sammanfattning : Chronic inflammation is together with excessive contraction of the airways key features of asthma. The aims of the thesis were to analyze the effect of inflammatory mediators on airway smooth muscle, using an in vitro model of cultured murine airways. LÄS MER

  7. 20. Synthesis and analysis of carbohydrates related to bacterial polysaccharides

    Författare :Hani Mobarak; Göran Widmalm; Ulf Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbohydrates; synthesis; conformation; NMR; O-antigen; computer-assisted structure elucidation; Organic Chemistry; organisk kemi;

    Sammanfattning : The outer surface of bacteria is composed of around 75% carbohydrates, which are vital for the bacteria to survive and communicate with the host biological system. The thesis discusses different properties of carbohydrates that are essential for understanding the bacterial behavior in biological systems. LÄS MER
