  1. 11. Collagenous colitis : The influence of inflammation and bile acids on intestinal barrier function

    Författare :Andreas Münch; Magnus Ström; Johan Söderholm; Magnus Simrén; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background and aims: Collagenous colitis (CC) is a diarrheal disorder with an incidence rate of 5-6/100000 inhabitants, affecting mainly middle-aged women. The diagnosis is made by histology of the colonic mucosa. Classical findings are a thickened subepithelial collagenous layer and chronic inflammation in the lamina propria. LÄS MER

  3. 12. Analysis of quality characteristics of radiotherapeutic photon beams

    Författare :Bo Nilsson; Stockholms universitet; []
    Nyckelord :Photon therapy; lepton contamination; photon contamination; surface dose; perturbation effects;

    Sammanfattning : The lepton and photon contamination of high energy photon beams for radiation therapy has been investigated computationally and experimentally. The contaminating particles will effect the quality of the beam by increasing the surface dose, degrading the uniformity of the beam, broadening the penumbra, and increasing the energy imparted outside the useful beam.

  4. 13. Counting and Tracking : Development and Use of New Methods for Detailed Analysis of Thrombus Formation

    Författare :Kjersti Tunströmer; Tomas Lindahl; Lars Faxälv; Nathaniel D Robinson; Judith Cosemans; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Blood platelets are a part of the complex system called haemostasis aimed at ensuring our blood’s continuous transport of oxygen and nutrients throughout the body. The transport is ensured by limiting blood loss due to vessel injury and in this process, the platelets form a plug in the damaged area, reinforced by the formation of fibrin. LÄS MER

  5. 14. 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

  7. 15. Evaluation of polysucrose 15000 as a marker of intestinal permeability

    Författare :Hans Öman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Polysucrose Permeability Intestinal Absorption Cell Memhrane Permeahility Molecular WeightMacromolecular systems Biological Markers Biological Transport Crohn Disease Arthritis; RheumatoidAnti-lnflammatory Agents; Non-Steroidal Chromium Radioisotop;

    Sammanfattning : Polysucrose (PS) is a synthetic copolymer of sucrose and epichlorohydrin, which can be produced in a variety of molecular sizes. The aim of the study was to evaluate the functionality of PS 15000, mean mol wt 14700, as a marker for intestinal permeability to macro molecules. LÄS MER
