  1. 11. Investigation and Prediction of Small Intestinal Precipitation of Poorly Soluble Drugs : a Study Involving in silico, in vitro and in vivo Assessment

    Författare :Sara Carlert; Hans Lennernäs; Bertil Abrahamsson; Patrick Augustijns; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gastrointestinal precipitation; crystallization; crystal nucleation; crystal growth; classical nucleation theory; poorly soluble drugs; drug absorption; biopharmaceutics classification system; in vitro in vivo correlations IVIVC ; in silico prediction; human intestinal fluid; dog intestinal fluid; simulated intestinal fluid; Biofarmaci; Biopharmaceutics;

    Sammanfattning : The main objectives of the present project were to increase the understanding of small intestinal precipitation of poorly soluble pharmaceutical drugs, investigate occurrence of crystalline small intestinal precipitation and effects of precipitation on absorption. The aim was to create and evaluate methods of predicting crystalline small intestinal drug precipitation using in vivo, in vitro and in silico models. LÄS MER

  2. 12. Genetic subtypes in unicellular intestinal parasites with special focus on Blastocystis

    Författare :Joakim Forsell; Birgitta Evengård; Margareta Granlund; Tom van Gool; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intestinal parasites; Blastocystis; Entamoeba; Giardia; molecular detection; PCR; subtype; intestinal microbiota; Sweden; Zanzibar; Clinical Bacteriology; klinisk bakteriologi;

    Sammanfattning : The development of molecular tools for detection and typing of unicellular intestinal parasites has revealed genetic diversities in species that were previously considered as distinct entities. Of great importance is the genetic distinction found between the pathogenic Entamoeba histolytica and the non-pathogenic Entamoeba dispar, two morphologically indistinguishable species. LÄS MER

  3. 13. Crohn's disease with special reference to intestinal malabsorption : a clinical study based on patients from northern Sweden

    Författare :Henry Nyhlin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Crohn s disease; intestinal absorption tests; muscle electrolytes; intestinal mucosa; terminal ileal function; SeHCAT;

    Sammanfattning : Crohn's disease is a chronic inflammatory bowel disease which may affect any part of the gastrointestinal tract with a preference for the terminal ileum and ileocaecal region. The disease was first described in 1932 and has increased during the last decades. LÄS MER

  4. 14. Challenge models and biomarkers of human intestinal barrier function

    Författare :María Fernanda Roca Rubio; Julia König; Robert J Brummer; Richard Forsgård; Kaatje Lenaerts; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacterial translocation; biomarkers; challenge models; intestinal barrier function; intestinal permeability; irritable bowel syndrome; physiological stress; psychological stress;

    Sammanfattning : The intestinal barrier is an essential component in maintaining human health, and several diseases and disorders have been associated with a disrupted intestinal barrier function. To evaluate the efficacy of different interventions intended to strengthen intestinal barrier function, there is a need for both appropriate challenge models as well as easily accessible biomarkers.

  5. 15. Biopharmaceutical aspects of intestinal drug absorption : Regional permeability and absorption-modifying excipients

    Författare :David Dahlgren; Hans Lennernäs; Erik Sjögren; Bertil Abrahamsson; Christer Tannergren; Steffansen Bente; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestinal permeability; absorption-modifying excipients; Biofarmaci; Biopharmaceutics;

    Sammanfattning : Before an orally administered drug reaches the systemic circulation, it has to dissolve in the intestinal fluids, permeate across the intestinal epithelial cell barrier, and pass through the liver. The permeation rate of drug compounds can be low and show regional differences.The thesis had two general aims. LÄS MER
