  1. 1. Gastrointestinal transit in health and disease

    Författare :Riadh Sadik; Göteborgs universitet; []
    Nyckelord :Small bowel transit; colonic transit; gastric emptying; gender; bile acid malabsorption; body mass index; celiac disease; portal hypertension; menopause;

    Sammanfattning : The uptake of nutrients occurs mainly in the small bowel. However, the time nutrients and other contents spend in the small bowel, i.e. the small bowel transit time is widely uncharacterised in man. LÄS MER

  3. 2. Applications of Magnetic Tracers in the Human Lung and Gastrointestinal Tract

    Författare :Mikael Forsman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse solution; gastrointestinal motility; inhaled particles; gastric emptying; welding dust; MPG; pulmonary clearance; occupational health; magnetopneumography; multipole analysis; transit time;

    Sammanfattning : The use of ferrimagnetic material as a tracer represents a noninvasive approach in physiological measurements. Concerning the lung, magnetopneumography, MPG, is a unique technique to estimate retained dust in the lung, using the magnetizable dust fraction as a tracer. First a strong constant magnetic field is briefly applied to the thorax. LÄS MER

  4. 3. Gastrointestinal Permeability and Motility in Inflammatory Bowel Disease

    Författare :Anas Kh. Al-Saffar; Per Hellström; Dominic-Luc Webb; Åsa Keita; Uppsala universitet; []
    Nyckelord :Gastrointestinal motility; intestinal permeability; Mucosal; Ghrelin; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Synchronized motility, permeability and secretory (hormones and enzymes) events are integral to normal physiology. Smooth muscle syncytium operates with enteric nervous system (ENS) and endocrine signalling to accommodate, mix and control passage of ingested materials. LÄS MER

  5. 4. Factors Influencing Iron Dialyzability and Uptake in In Vitro Models

    Författare :Susan Salovaara; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferric iron; iron dialyzability; Caco-2 cells; pea protein; organic acids; gastrointestinal model; transit time; iron absorption; ferrous iron;

    Sammanfattning : The availability or iron from a meal is influenced by numerous factors. This thesis deals with three of them: organic acids, plant proteins (pea and soy), and transit time through the stomach and small intestine. LÄS MER

  7. 5. Changes in Gastrointestinal Function and Patient-scored Symptoms after Bariatric Surgery

    Författare :Khalid Elias; Magnus Sundbom; Ville Wallenius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The obesity pandemic is rapidly increasing. Individuals with obesity are affected by obesity-related comorbidities, reduced life expectancy, and reduced quality of life. The most effective treatment for obesity and its comorbidities is bariatric surgery, restoring the physical component of quality of life. LÄS MER
