1. 6. Enantioseparation of drugs and related compounds using chiral mobile phase additives

   Författare :Ngoc Hang Huynh; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Sammanfattning : Neutral and anionic chiral mobile phase additives have been employed to separate enantiomers of drugs and related compounds using aqueous buffer solution and hydro-organic solvent mixtures as mobile phases.Ester derivatives of tartaric acid, e. g. LÄS MER

3. 7. Neural control of colonic epithelial transport, motility and permeability in vivo. An experimental study in anaesthetized rats

   Författare :Ying Sun; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enteric nervous system; colonic motility; transmural potential difference; net; fluid transport; permeability; bile acid; nitric oxide; inflammatory bowel disease;

   Sammanfattning : Colonic dysfunction may result in diarrhoea, abdominal pain or constipation, andinflammatory bowel disease, bile acid malabsorption and particularly irritable bowelsyndrome are very common disorders. The role of the enteric nervous system (ENS) inthese diseases is largely unknown. LÄS MER

4. 8. Adaptation of ventricular repolarization to heart rate change in humans

   Författare :Karl-Jonas Axelsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac memory; hysteresis; long QT syndrome; QT adaptation; vectorcardiography; ventricular repolarization;

   Sammanfattning : Background: Life-threatening cardiac rhythm disturbances and sudden death are common manifestations of heart disease. Disturbances in electrical recovery (ventricular repolarization; VR) are important mechanisms behind ventricular arrhythmias, which often occur in relation to changes in heart rate (HR). LÄS MER

5. 9. Estimation of acute toxicity by using the differentiated neuronal progenitor C17.2 cell model

   Författare :Jessica Lundqvist; Anna Forsby; Ann-Kristin Östlund Farrants; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neurotoxicity; C17.2; cell membrane potential; Optimisation culture condition; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : The authorities in Europe and United States request information regarding possible toxicity for substances that are produced in one tonne or more per year. Estimation of acute systemic toxicity is conducted in vivo using mice or rats. LÄS MER

7. 10. Ghrelin action on gastrointestinal functions and appetite in rat and man

   Författare :Fredrik Levin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Ghrelin; ghrelin-receptors; gastrointestinal motility; migrating myoelectric complex; gastric acid secretion; gastric emptying; appetite; food intake; disinhibition; restraint; hunger; obesity;

   Sammanfattning : To study the effect of ghrelin on the contractility of smooth muscle strips in vitro as well as the effects on fasting small bowel motility and acid secretion in vivo in rats and gastric emptying in rats and humans. To study the effect of peripherally administered ghrelin on plasma levels of glucose, insulin, glucagon, orexin A (OXA), somatostatin and gastrin in rats and ghrelin, cholecystokinin (CCK), glucagonlike peptide-1 (GLP-1), peptide YY (PYY) and motilin in humans.
