  1. 26. Non-digestible Polysaccharides and Intestinal Barrier Function : specific focus on its efficacy in elderly and patients with Crohn’s disease

    Författare :John-Peter Ganda Mall; Robert Jan Brummer; Ida Schoultz; Åsa Keita; Mikael Wirén; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-digestible polysachharides; beta-glucan; arabinoxylan; barrier function; permeability; Ussing chamber; elderly; Crohn’s disease;

    Sammanfattning : A large number of elderly suffer from gastrointestinal (GI) symptoms such as constipation and diarrhoea. The underlying mechanisms of age-acquired GI symptoms are not well studied but are necessary to clarify in order to recommend the right treatment. LÄS MER

  3. 27. Exploring the structure of oligo- and polysaccharides : Synthesis and NMR spectroscopy studies

    Författare :Hanna Jonsson; Göran Widmalm; Antonio Molinaro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; NMR spectroscopy; synthesis; lipopolysaccharides; conformational studies; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : A deeper understanding of the diversity of carbohydrates and the many applications of oligo- and polysaccharides found in nature are of high interest. Many of the processes involving carbohydrates affect our everyday life. This thesis is based on six papers all contributing to an extended perspective of carbohydrate property and functionality.

  5. 29. Structures of some bacterial polysaccharides with focus on pneumococcal polysaccharides and their associated C-polysaccharide

    Författare :Camilla Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Streptococcus pneumoniae; Pneumococcus; C-polysaccharide; Sphingomonas paucimoblis; Hafnia alvei; NMR spectroscopy; capsular polysaccharide; lipopolysaccharide; structure;

    Sammanfattning : This thesis describes the chemical structures of the capsular polysaccharides from Streptococcus pneumoniae types 18B, 32F, and 32A. The structure of the pneumococcal common antigen, C-polysaccharide, from a non-capsulated pneumococcal strain, CSR SCS2, is described and the structure of the C-polysaccharide associated with pneumococcal types 18B, 32F, and 32A.

  7. 30. Hemicelluloses and other Polysaccharides for Wood Adhesive Applications

    Författare :Emelie Norström; Eva Malmström; Orlando Rojas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The growing environmental awareness has led to an increased interest in bio-based polymers as replacement for fossil-based materials. The purpose of the work described in this thesis was to investigate the possibility of using hemicelluloses and other polysaccharides as replacement for fossil-based polymers in wood adhesives.
