  1. 1. Refined in vitro Models for Prediction of Intestinal Drug Transport Role of pH and Extracellular Additives in the Caco-2 Cell Model

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sibylle Neuhoff; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Caco-2 cells; membrane permeability; drug permeation; drug efflux ratios; drug uptake ratios; Cremophor EL; bovine serum albumin; pH-dependent permeability; drug transport; FARMACI; PHARMACY; FARMACI;

    Abstract : Drug transport across the intestinal epithelium is roughly predicted from permeability values obtained from Caco-2 cell monolayers. This thesis examines the important role of pH and extracellular additives for increasing the reliability and predictivity of the in vitro screening system, Caco-2. READ MORE

  2. 2. Oxidation of marine oils during in vitro gastrointestinal digestion and its effects on stress in human intestinal Caco-2 cells

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Cecilia Tullberg; [2017]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lipid oxidation; human digestive fluids; LC n-3 PUFAs; Caco-2 cells; marine oils; HNE; MDA; in vitro digestion; HHE; gastrointestinal; aldehydes;

    Abstract : Marine oils are attracting public interest due to the preventive effects, e.g., on inflammation, which are linked to the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). However, LC n-3 PUFAs are highly susceptible to oxidation, which could interfere with their positive effects. READ MORE

  3. 3. Bioactive Food Compounds with Cancer Preventing Effects in the Colon Focus on Ferulic Acid, para-Coumaric Acid and Lactoferricin

    University dissertation from Lund University (Media-Tryck)

    Author : Birgit Janicke; Lunds universitet.; Lund University.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caco-2; Gene expression; Cell proliferation; Cell cycle; Bioactive food compounds; Colon cancer; Ferulic acid; para-Coumaric acid; Lactoferricin;

    Abstract : Colorectal cancers are globally ranked as the third most common cancer form in terms of incidence and mortality. Diet has long been considered as one of the main factors affecting population outcome regarding development of cancer in the colon. READ MORE

  4. 4. Effects of Microparticulate Drug Delivery Systems Tissue Responses and Transcellular Transport

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Eva Ragnarsson; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; microparticles; vaccine; pDNA vaccine; cationic polymer; gene expression analysis DNA array ; Caco-2; follicle-associated epithelium FAE ; M cell; transcytosis; Yersinia pseudotuberculosis; Galenisk farmaci; PHARMACY Pharmaceutics; FARMACI Galenisk farmaci;

    Abstract : Over the past decade, the development of macromolecular drugs based on peptides, proteins and nucleic acids has increased the interest in microparticulate drug delivery, i.e., the delivery of drug systems in the nanometer and micrometer ranges. READ MORE

  5. 5. Intestinal Permeability and Presystemic Extraction of Fexofenadine and R/S-verapamil

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Christer Tannergren; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; Bioavailability; Fexofenadine; Verapamil; P-glycoprotein; CYP3A4; OATP; Enantioselective; Permeability; Caco-2; Intestinal perfusion; Biofarmaci; PHARMACY Biopharmacy; FARMACI Biofarmaci;

    Abstract : The main objective of this thesis was to investigate the in vivo relevance of membrane transporters and cytochrome P450 (CYP) 3A4-mediated metabolism in the intestine and liver for the bioavailability of drugs in humans after oral administration.In the first part of the thesis, the main transport mechanisms involved in the intestinal absorption and bioavailability were investigated for fexofenadine, a minimally metabolized drug, which is a substrate for P-glycoprotein (P-gp) and members of organic anion transporting polypeptide (OATP) family.
