  1. 6. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine

    Author : Moorix Mo-Wai Yeung; Sten Hammarström; Marie-Louise Hammarström; Marita Troye-Blomberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestine; ulcerative colitis; lymphoid aggregates; intraepithelial lymphocytes; lamina propria lymphocytes; γδT-cells; cytokines; IL-2; carcinoembryonic antigen; biliary glycoprotein; epithelial cells; glycocalyx;

    Abstract : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. READ MORE

  2. 7. Digestion and Absorption of Sphingomyelin from Milk

    Author : Lena Nyberg; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastro-enterology; intestine; sphingolipid; ceramidase; sphingomyelinase; ceramide; Gastroenterologi;

    Abstract : Sphingomyelin (SM) is a major component of mammalian cell membranes. Due to its widespread occurrence it is a dietary component, occurring mainly in milk, eggs, meat and fish. In the cell membrane SM was earlier considered to be only a structural element, which interacts with cholesterol and forms a system for bilayer stabilization. READ MORE

  3. 8. Internal Dosimetry Development and Evaluation of Methods and Models

    Author : Lena M Jönsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; crypt cells; intestine; radionuclide; scintillation camera; sestamibi; activity quantification; conjugate view method; Monte Carlo simulation; internal dosimetry; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; medicinsk instrumentering; radiologi;

    Abstract : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. READ MORE

  4. 9. The functional role of the MUC17-based glycocalyx

    Author : Sofia Jäverfelt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intestine; Glycocalyx; Membrane mucin; Host defenses;

    Abstract : Our gastrointestinal tract harbors trillions of bacteria that are chemically and spatially separated from the intestinal epithelium. Maintaining an intact mucosal barrier is essential as increased bacterial contact is associated with inflammatory bowel diseases such as Crohn´s disease. READ MORE

  5. 10. Defence capabilities of human intestinal epithelial cells

    Author : Anna Fahlgren; Sten Hammarström; Marie-Louise Hammarström; Gudmundur Gudmundsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; intestine; mucosa; epithelium; antimicrobial; defensins; glycocalyx; ulcerative colitis; Crohn´s disease; celiac disease; Immunologi; Immunology; Immunologi; immunologi; Immunology;

    Abstract : The epithelial cells lining the intestinal mucosa separate the underlying tissue from components of the intestinal lumen. Innate immunity mediated by intestinal epithelial cells (IECs) provides rapid protective functions against microorganisms. Innate immunity also participates in orchestrating adaptive immunity.
