  1. 11. 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

  3. 12. 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.

  4. 13. 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

  5. 14. Novel Circulating and Tissue Biomarkers for Small Intestine Neuroendocrine Tumors and Lung Carcinoids

    Författare :Tao Cui; Valeria Giandomenico; Kjell Öberg; Apostolos V. Tsolakis; Marco Volante; Uppsala universitet; []

    Sammanfattning : Small intestine neuroendocrine tumors (SI-NETs) and lung carcinoids (LCs) are relatively indolent tumors, which originate from neuroendocrine (NE) cells of the diffuse NE system. Metastases can spread before diagnosis. Thus, potential cures become unavailable, which entitles new biomarker development. LÄS MER

  7. 15. Digestion and Absorption of Sphingomyelin from Milk

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

    Sammanfattning : 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. LÄS MER
