Article Abstract

The result of a prospective trial of 40 patients with duodenal ulcer treated either by proximal gastric vagotomy (antrum innervated) or by selective vagotomy (antrum denervated) shows that they are equally effective in reducing gastric acid and pepsin secretion. Preservation of antral innervation by proximal gastric vagotomy reduces gastric secretion as effectively as denervation of the entire stomach.

We previously reported the presence of P2X3 purinoceptors (P2X3)-expressing subserosal afferent nerve endings consisting of net- and basket-like nerve endings in the rat gastric antrum. These nerve endings may morphologically be vagal mechanoreceptors activated by antral peristalsis. The present study investigated immunoreactivities for vesicular glutamate transporter (VGLUT) 1 and VGLUT2 as well as exocytosis-related proteins, i.

Electromechanical coupling and anatomy of the in vivo gastroduodenal junction.

Am J Physiol Gastrointest Liver Physiol

July 2024

Auckland Bioengineering Institute, University of Auckland, Auckland, New Zealand.

Few biomarkers support the diagnosis and treatment of disorders of gut-brain interaction (DGBI), although gastroduodenal junction (GDJ) electromechanical coupling is a target for novel interventions. Rhythmic "slow waves," generated by interstitial cells of Cajal (ICC), and myogenic "spikes" are bioelectrical mechanisms underpinning motility. In this study, simultaneous in vivo high-resolution electrophysiological and impedance planimetry measurements were paired with immunohistochemistry to elucidate GDJ electromechanical coupling.

The stomach is the primary reservoir of the gastrointestinal tract, where ingested content is broken down into small particles. Coordinated relaxation and contraction is essential for rhythmic motility and digestion, but how the muscle motor innervation is organized to provide appropriate graded regional control is not established. In this study, we recorded neuromuscular transmission to the circular muscle using intracellular microelectrodes to investigate the spread of the influence of intrinsic motor neurons.

Introduction: Polycystic ovary syndrome (PCOS) seems to be associated with increased ovarian sympathetic nerve activity and in rodent models of PCOS reducing the sympathetic drive to the ovary, through denervation or neuromodulation, improves ovulation rate. We hypothesised that sympathetic nerves work with gonadotropins to promote development and survival of small antral follicles to develop a polycystic ovary phenotype.

Methods: Using a clinically realistic ovine model we showed a rich sympathetic innervation to the normal ovary and reinnervation after ovarian transplantation.

Luminal Chemoreceptors and Intrinsic Nerves: Key Modulators of Digestive Motor Function.

Adv Exp Med Biol

January 2023

Gastroenterology Unit, Flinders Medical Centre & College of Medicine and Public Health, Flinders University, Adelaide, SA, Australia.

This chapter reviews data on the pathways by which luminal, mainly duodenal, chemoreceptors modulate gastro-pyloro-duodenal motor function to control emptying of nutrients into the small intestine. The vagus mediates proximal gastric relaxation caused by nutrient stimulation of duodenal/jejunal mucosal chemoreceptors. Modulation of the spatial patterning and inhibition of antral contractions during duodenal chemoreceptor activation are somewhat conflicting: both vagal control and ascending intramural nerves appear to play a role.
