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

    Author : Markus Sjöblom; Gunnar Flemström; Olof Nylander; Karl EO Åkerman; Per M. Hellström; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. The neuromodulatory effect, safety and effectiveness of vagus nerve stimulation

    Author : David Revesz; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vagus nerve stimulation; VNS; Neuromodulation; Neurogenesis; VBLOC; Epilepsy; Depression; Safety; Efficacy; Effectiveness;

    Abstract : Vagus nerve stimulation (VNS) is an adjunctive palliative neuromodulatory treatment for drug resistant epilepsy (DRE) and chronic depression. It has also been proposed as a treatment for many other conditions such as chronic pain, heart failure, and Alzheimer’s disease. READ MORE

  5. 3. The laryngeal mucosa and the superior laryngeal nerve of the rat : an immunohistochemical and electron microscopic study

    Author : Siw Domeij; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superior laryngeal nerve; paraganglia; substance P; calcitonin gene-related peptide; neuropeptide Y; vasoactive intestinal polypeptide; enkephalin; mast cells; electron microscopy; immunohistochemistry;

    Abstract : Neuropeptides are present in nerve fibers of the upper and lower airways. Local release of these substances may be of importance for the pathophysiology of airway disorders and may play a role in responses to different stimuli. However, little is known about the distribution of neuropeptides in the larynx. READ MORE

  6. 4. Role of corticotropin-releasing factor, somatostatin and leptin in vagal nerve function and control of gastric emptying

    Author : Ulrika Smedh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The overall aim of this thesis was to study the effects of centrally acting CRF and leptin, and peripherally acting somatostatin on gastric emptying of glucose. Freely moving rats bearing chronic intragastric fistulas received intragastric infusions (1.0 ml/min) of glucose (12.5 % or 25 %) during 6-18 min. READ MORE

  7. 5. Neuro-immune communication: role of the vagus nerve : an electrophysiological study

    Author : Violeta Bucinskaite; Karolinska Institutet; Karolinska Institutet; []
    Keywords : cholecystokinin; CCKA; CCKB; cytokines; IL-1[beta]; illness; nerve activity; NIDDM; OLETF; the vagus; vagotomy;

    Abstract : Defence mechanisms involve close interactions between the nervous and immune systems following an immune challenge. The vagal pathways which modulate major visceral functions under normal conditions are also important neural pathways for the transmission of information on peripheral conditions to the CNS. READ MORE
