  1. 21. Complement-dependent defence against bacterial infection. Studies in C2 deficiency

    Författare :Barbro Selander; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibody responses; polysaccharide antigens; vaccination; mannan-binding lectin MBL ; complement; C2 deficiency; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : The complement system is critically involved in defence against bacterial infection. C2 deficiency is, apart from mannan-binding lectin (MBL) deficiency, the most common homozygous complement deficiency among Caucasians. LÄS MER

  3. 22. Structural studies of bacterial carbohydrate antigens with focus on oral commensal bacteria

    Författare :Niklas Bergström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Streptococcus mitis; Streptococcus pneumoniae; Vibrio cholerae; polysaccharide; structure; Nuclear magnetic resonance spectroscopy NMR ; Mass spectrometry MS .;

    Sammanfattning : 90% of the total number of cells in the human body consist of the normal bacterial flora. These bacteria are mostly not harmful and, indeed, even beneficial as long as they remain physiologically outside the body, e.g., within the gastro-intestinal tract. LÄS MER

  4. 23. Development of Capacitive Biosensors for Monitoring of Bacterial Toxins and Other Biomolecules

    Författare :Mahmoud Labib; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme-linked immunosorbent assay; self-assembled monolayers; competitive capacitive biosensing; cholera toxin; Capacitive biosensor; surface plasmon resonance; staphylococcal enterotoxin B; nanogold; human immunoglobulin G; glucose;

    Sammanfattning : Sensing and quantification of biomolecules are becoming increasingly important in medical diagnostics, bioprocess technology and recently in homeland security. The majority of techniques currently employed to interrogate biomolecules require some type of radio-, enzymatic- or fluorescent-labeling. LÄS MER

  5. 24. Dietary Fibre in Fermented Oats and Barley

    Författare :Adele Lambo; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Näringslära; Nutrition; short-chain fatty acids ; exopolysaccharides; fermentation; barley; oats; Dietary fibre polysaccharides; cholesterol ;

    Sammanfattning : The physiological characteristics of native and bacterial exopolysaccharides (EPS) in oats and barley-based fermented products were studied in relation to the physico-chemical properties. Article I presents a parallel-randomized double blind clinical trial using a dairy-based product (control), an oat-based product (fermented with V2, which is a mixture (1:1) of Lactobacillus delbrueckii subsp.

  7. 25. Structural studies and modification of some carbohydrate-containing bacterial antigens, and mass spectrometric studies of oligosaccharides as their permethylated alditols

    Författare :Frank Lindh; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The structures of the bacterial antigens of two capsular polysaccharides from the species Klebsiella and a lipopolysaccharide from Escherichia coli have been elucidated. The principle methods used in the investigation were methylation analysis, partial acid hydrolysis. LÄS MER
