  1. 21. Influence of Genes and Post-translational Modifications in the Pathogenesis of Light Chain Amyloidosis

    Författare :Stina Enqvist; Per Westermark; Robert Kisilevsky; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Amyloid is formed when a normally soluble protein undergoes conformational changes that results in self-aggregation. The pathogenic protein in light chain amyloidosis is an immunoglobulin light chain produced by a plasma cell clone mainly in the bone marrow. LÄS MER

  3. 22. Interactions between dietary chicory, gut microbiota and immune responses

    Författare :Haoyu Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis provides a better understanding of interactions between diet, gut microbiota, and immune responses to a specific dietary fiber source, chicory (Cichorium intybus L). This was achieved by examining the impact of chicory fiber on animal performance, digestibility, gut development, commensal bacteria community structure in small and large intestine, and follow-up reactions with specific immune components, cytoprotective heat shock protein (HSP) 27 and 72, in vivo and in vitro.

  4. 23. Measurements of the 234U(n,f) Reaction with a Frisch-Grid Ionization Chamber up to En=5 MeV

    Författare :Ali Al-Adili; Pomp Stephan; Franz-Josef Hambsch; Michael Österlund; Talou Patrick; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fission; U-234; Neutron; Uranium; Resonance; Ionization Chamber; Frisch-grid; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : This study on the neutron-induced fission of 234U was carried out at the 7 MV Van de Graaff accelerator of IRMM in Belgium. A Twin Frisch-Grid Ionization Chamber (TFGIC) was used to study 234U(n,f) between En = 0.2 and 5.0 MeV. LÄS MER

  5. 24. Seaweed Invasions and Novel Chemical Defences

    Författare :Swantje Enge; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biological invasions; enemy release; increased competitive ability; novel weapon; chemical defence; plant-herbivore interactions; competition; seaweeds; Bonnemaisonia hamifera;

    Sammanfattning : Biological invasions pose a risk to the biodiversity and the functioning of ecosystems in invaded areas. The reasons why some introduced species become dominant and widespread in their new environments is still largely an unsettled question. LÄS MER

  7. 25. Structure and Dynamics of Membrane Associated Peptides

    Författare :Henrik Biverståhl; Lena Mäler; Charles R. Sanders; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biofysik; Biophysics; biofysik;

    Sammanfattning : The peptide-membrane interaction is a key element for many biological functions, from cell signaling to cell internalization. In this thesis the peptide-membrane interaction of six different peptides have been studied with respect to their structure, membrane location and dynamics with spectroscopic methods. LÄS MER
