  1. 1. Prevention of Postoperative Duodenal Ileus by COX-2 Inhibition Improves Duodenal Function in Anaesthetised Rats

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : John Sedin; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; duodenum; motility; enteric nervous system; luminal alkalinisation; CFTR; VIP; luminal Cl-; fluid secretion; solute absorption; mucosal permeability; 51Cr-EDTA; luminal osmolality; luminal hypertonicity; glucose; mannitol; orange juice; parecoxib; hexamethonium; mecamylamine; Physiology; Fysiologi;

    Abstract : Abdominal surgery inhibits gastrointestinal motility, a phenomenon referred to as postoperative ileus. Since the postoperative ileus disturbs duodenal physiology it is important to minimize the side effects of this condition. READ MORE

  2. 2. Luminal Hypotonicity and Duodenal Functions An Experimental Study in the Rat

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Liselotte Pihl; Uppsala universitet.; [2007]
    Keywords : Physiology; luminal alkalinization; mucosal permeability; osmolality; cyclooxygenase-2; rat; duodenum; jejunum; motility; enteric nervous system; Fysiologi;

    Abstract : After drinking water, the fluid quickly leaves the stomach thereby creating a hypotonic luminal environment in the duodenum. This in turn constitutes a potential threat to the integrity of the duodenal epithelium. It therefore seems highly likely that luminal hypotonicity activates physiological mechanisms that aim to increase luminal osmolality. 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. Regulation of Duodenal Mucosal Barrier Function and Motility The Impact of Melatonin

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Sommansson; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; bicarbonate secretion; duodenum; enteric nervous system; enterochromaffin cell; ethanol; hexamethonium; in vivo; mecamylamine; motility; mucosal permeability; parecoxib; rat; Physiology; Fysiologi;

    Abstract : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired.

  5. 5. Sleep and cardiovascular health in women : The Stockholm female coronary risk study

    University dissertation from Stockholm : Karolinska Institutet, Department of Public Health Sciences

    Author : Constanze Leineweber; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; prognosis; sleep; women;

    Abstract : Background: Both sleep disturbances and snoring has been related to an increased mortality and CHD risk. However, despite the fact that women report sleep difficulties more often than men, most studies have been done in men. A large amount of the studies is of cross-sectional character and no conclusions about cause and effect can be drawn. READ MORE
