  1. 1. The enteric nervous sytem and infectious diarrhoea. An experimental study in mouse and rat

    Author : Shirin Kordasti; Göteborgs universitet.; Gothenburg University.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rotavirus; cholera; secretion; potential difference; enteric nervous system;

    Abstract : Aim: To evaluate the role of the enteric nervous system in one of the most common types of infectious diarrhoea worldwide, rotavirus infection, and to further clarify the mechanisms behind neurally mediated intestinal secretion. Methods: The experiments were performed on neonatal and adult mice and adult rats. Experimental setups: In vitro: 1. READ MORE

  2. 2. Bile Acid Induced Diarrhoea Pathophysiological and Clinical Aspects

    Author : Antal Bajor; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diarrhoea; bile acid transport; bile acid synthesis; 75SeHCAT reproducibility; C4; budesonide; collagenous colitis; in vitro; malabsorption; ASBT; intestinal secretion; potential difference; manometry;

    Abstract : A common cause for referral to gastroenterologists is chronic watery diarrhoea. Approximately 40% of these patients have idiopathic bile acid malabsorption (BAM) ? a condition with unknown aetiology. The 75SeHCAT test, which correlates inversely with faecal excretion and hepatic synthesis of bile acids, is used to diagnose BAM. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tina W. Knutson; Uppsala universitet.; [2000]
    Keywords : 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; MEDICINE Surgery; MEDICIN Kirurgi; anestesiologi; Anaesthesiology;

    Abstract : 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. 4. Radial Basis Function generated Finite Difference Methods for Pricing of Financial Derivatives

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Slobodan Milovanović; Uppsala universitet.; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; Finite difference; Computational finance; Pricing of financial derivatives; Option pricing; Partial differential equation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The purpose of this thesis is to present state of the art in radial basis function generated finite difference (RBF-FD) methods for pricing of financial derivatives. This work provides a detailed overview of RBF-FD properties and challenges that arise when the RBF-FD methods are used in financial applications. READ MORE

  5. 5. Structural, Kinetic and Thermodynamic Aspects of the Crystal Polymorphism of Substituted Monocyclic Aromatic Compounds

    University dissertation from Stockholm : KTH Royal Institute of Technology
