  1. 1. Proteomics-informed analysis of drug disposition in the human liver and small intestine

    Författare :Christine Wegler; Per Artursson; Pär Matsson; Tommy B Andersson; Manthena Varma; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; protein concentration; drug disposition; drug transport; drug metabolism; human small intestine; human liver; human hepatocytes; human liver microsomes; inter-individual variability; drug clearance; obesity; prediction model; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Orally administered drugs are absorbed in the intestine and generally metabolized in the liver. Therefore, understanding factors determining drug distribution and elimination in these tissues is important. LÄS MER

  3. 2. Expression of Genes Encoding for Drug Metabolism in the Small Intestine

    Författare :Monica Lindell; Hans Lennernäs; Matti Lang; Olavi Pelkonen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; CYPs; UGTs; interindividual variation; small intestine; human; rat; artemisinin; CAR-receptor regulation; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi;

    Sammanfattning : This investigation focused on the mRNA expression of drug metabolising Cytochromes P-450 (CYP) and UDP-glucuronosyltransferases (UGT) and the transport protein P-glycoprotein (Pgp) in the small intestine of humans and rats.The mRNA expression of the investigated genes in the human small intestine (duodenum) varies between individuals giving each one of us personal profile.

  4. 3. Proteomic and Functional Analysis of In Vitro Systems for Studies of Drug Disposition in the Human Small Intestine and Liver

    Författare :Magnus Ölander; Per Artursson; Pär Matsson; Edward L. LeCluyse; Volker Lauschke; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; drug disposition; ADMET; drug transport; drug metabolism; hepatotoxicity; small intestine; liver; caco-2; human hepatocytes; cryopreservation; apoptosis; liver zonation; non-parenchymal cells; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : To reach the bloodstream, an orally administered drug must be absorbed through the small intestine and avoid extensive clearance in the liver. Estimating these parameters in vitro is therefore important in drug discovery and development. LÄS MER

  5. 4. Membrane transport and the human small intestine : Relation to mucosal protection, intestinal anaphylaxis and nitric oxide

    Författare :Tina W. Knutson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; albumin; bicarbonate secretion; carbonic anhydrase; dopamine; duodenum; histamine; humans; hyaluronan; intestinal anaphylaxis; intestinal obstruction; jejunum; lidocaine; LOC-I-GUT; nitecapone; nitric oxide; potential difference; prostaglandins; segmental intestinal perfusion; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

    Sammanfattning : The tightly adherent monolayer of epithelial cells that line the luminal side of the intestine provides a dynamic and highly regulated barrier to the passive and active transport of ions, water and macromolecules. Cathecol-O-methyl transferase inhibition prevents tissue degradation of catecholaminesincluding dopamine and intracellular carbonic anhydrase activity is an important regulator of ion and water transport in the small intestine.

  7. 5. Human intraepithelial lymphocytes : a comparative study of phenotype, morphology, and functional properties of intraepithelial lymphocytes in gut and oral mucosa

    Författare :Carina Lundqvist; Marie-Louise Hammarström; Sten Hammarström; Per Brandtzaeg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intraepithelial lymphocytes; alimentary tract; intestinal epithelium; gut luminal antigens; gingiva; γδ T cells; immunoelectron microscopy; cytokine mRNA; RT-PCR; extrathymic T cell maturation; RAG-1; periodontitis; mucosal immune system; CD4-CD8- αβ T cells; CD8 γδ T cells;

    Sammanfattning : Human intraepithelial lymphocytes (IEL) constitute a unique cell population situated in the first line of defense of the alimentary tract. Here they are continuously exposed to a massive antigenic load of high complexity. However, different conditions prevail along the alimentary tract. LÄS MER
