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

    Författare :John Sedin; Olof Nylander; Markus Sjöblom; Lars Fändriks; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 12. The Duodenal Mucosal Bicarbonate Secretion : Role of Melatonin in Neurohumoral Control and Cellular Signaling

    Författare :Markus Sjöblom; Gunnar Flemström; Olof Nylander; Karl EO Åkerman; Per M. Hellström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; alkaline secretion; central nervous system; duodenal enterocyte; duodenal ulcer; duodenum; enterochromaffin cell; human; intraarterial; intracellular calcium; intracerebroventricular; melatonin; rat; vagal nerve; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. LÄS MER

  4. 13. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin

    Författare :Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 14. Role of Melatonin, Neuropeptide S and Short Chain Fatty Acids in Regulation of Duodenal Mucosal Barrier Function and Motility

    Författare :Wan Salman Wan Saudi; Markus Sjöblom; Olof Nylander; Mark Berner-Hansen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; rat; in vivo; duodenum; enteric nervous system; paralytic ileus; parecoxib; bicarbonate secretion; motility; ethanol; HCl; melatonin; neuropeptide S; short chain fatty acids; chemosensing; Physiology; Fysiologi;

    Sammanfattning : The duodenal epithelium is regularly exposed to HCl, digestive enzymes, bacteria and toxins, and sometimes also to ethanol and drugs. The imbalance of aggressive factors in the intestinal lumen and mucosal barrier function increases the risk of tissue injury and inflammation. LÄS MER

  7. 15. Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea

    Författare :Jonas Appelberg; Göran Hedenstierna; Christer Janson; Karl Franklin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Sleep; Ventilation; Sleep apnea syndromes; Snoring; Lung volume; Respiration; Computed tomography; Ventilatory response; Ventilation-perfusion; Airway closure; Fysiologi; Physiology; Fysiologi; klinisk fysiologi; Clinical Physiology;

    Sammanfattning : Obstructive sleep apnea (OSA) appears to affect up to 5% of the population. The extent to what pulmonary function awake and during sleep relates to obstructive breathing and hypoxemia during sleep in these patients is unclear. LÄS MER
