  1. 6. Intestinal transport of levodopa : Implications for the therapy of Parkinson's disease

    Författare :Dag Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Parkinson s disease; levodopa. duodenal Infusion; intestinal permeability; positron emission tomography; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Levodopa has been the basic treatment of patients with Parkinson's disease for the last 30 years. However, with time nearly all patients develop fluctuations in motor performance correlated to levodopa plasma concentrations. LÄS MER

  3. 7. Intestinal absorption of drugs : The impact of regional permeability, nanoparticles, and absorption-modifying excipients

    Författare :Carl Roos; Hans Lennernäs; Erik Sjögren; Martin Brandl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Permeability; intestinal absorption; regional permeability; nanoparticles; nanosuspensions; absorption-modifying excipients; AMEs; Biofarmaci; Biopharmaceutics;

    Sammanfattning : For successful delivery of orally given drug products, the drug compounds must have adequate solubility and permeability in the human gastrointestinal tract. The permeability of a compound is determined by its size and lipophilicity, and is usually evaluated in various pre-clinical models, including rat models. LÄS MER

  4. 8. Experimental Disruption of Intestinal Mucosal Homeostasis : Exploring the Protective Potential of Melatonin and Misoprostol

    Författare :Karsten Peters; Markus Sjöblom; Hans Lennernäs; David Dahlgren; Åsa Keita; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intestinal barrier dysfunction; intestinal permeability; chemotherapy-induced mucositis; doxorubicin; 5-fluorouracil; apoptosis; proliferation; melatonin; misoprostol; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The intestinal mucosa serves as a protective layer that separates the intestinal contents from the underlying tissues. It restricts harmful substances, pathogens, and undigested particles from entering the bloodstream. LÄS MER

  5. 9. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa

    Författare :Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestinal mucosa; intraepithelial lymphocyte; lamina propria lymphocyte; γδ T cell; regulatory T cell; cytotoxicity; cytokine; basal lymphoid aggregate; ulcerative colitis; Crohn s disease;

    Sammanfattning : The epithelial lining of the gut must allow immediate contact with beneficial components as nutrients and normal microflora. At the same time it runs the constant risk of attack from pathogenic microbes and noxious agents. LÄS MER

  7. 10. Human intestinal alkaline phosphatase : tissue expression and serum levels

    Författare :Ulla Domar; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human alkaline phosphatase; intestinal alkaline phosphatase; blood; blood group; lipid; monoclonal antibody; immunohistochemistry; liver; kidney; pancreas; liver disease; inflammatory bowel disease;

    Sammanfattning : Human alkaline phosphatase (ALP) comprises four isozymes, viz liver/bone/ kidney or tissue unspecific (AP), intestinal (LAP), placental (PLAP) and germ cell or PLAP-like alkaline phosphatase, with their main expression in specific tissues as indicated by their names. The isozymes are coded by different genes, but they are closely related, with more than 50% amino acid sequence homologies. LÄS MER
