The human colon: Evidence for degenerative changes during aging and the physiological consequences

open access: yesNeurogastroenterology &Motility, EarlyView.
Reduced nociceptor innervation can explain diminished abdominal pain among the elderly. Degenerative changes occur within the colon wall, especially ascending colon. Mechanisms may include senescence‐like activity and inflammaging. Constipation is more likely to occur during age‐related challenges affecting functions of the bowel that now have reduced ...

Role of the thalamic parafascicular nucleus cholinergic system in the modulation of acute corneal nociception in rats [PDF]

open access: yesVeterinary Research Forum, 2011
The present study investigated the effects of microinjections of acetylcholine (a cholinergic agonist), physostigmine (a cholinesterase inhibitor), atropine (an antagonist of muscarinic cholinergic receptors) and hexamethonium (an antagonist of nicotinic

Mechanisms of enteric neuropathy in diverse contexts of gastrointestinal dysfunction

open access: yesNeurogastroenterology &Motility, EarlyView.
Abstract The enteric nervous system (ENS) commands moment‐to‐moment gut functions through integrative neurocircuitry housed in the gut wall. The functional continuity of ENS networks is disrupted in enteric neuropathies and contributes to major disturbances in normal gut activities including abnormal gut motility, secretions, pain, immune dysregulation,

Spontaneous enteric nervous system activity generates contractile patterns prior to maturation of gastrointestinal motility

open access: yesNeurogastroenterology &Motility, EarlyView.
Spontaneous neuronal network activity is critical for circuit maturation, yet whether this is a feature of enteric nervous system development has yet to be established. Here, we identify clustered ripples, a previously undescribed form of neurogenic gastrointestinal motility that shares many features with spontaneous neuronal networks in other systems.

Oral Adverse Effects of Antipsychotic Medications: A Case/Noncase Analysis of EudraVigilance Data

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective Neuropsychiatric disorders are associated with poor oral health, with antipsychotics as potential contributors. This study aimed to analyse the oral adverse effects of antipsychotics using the EudraVigilance database. Methods A case/noncase analysis was conducted to calculate reporting odds ratios (ROR) and assess the ...

The possible mechanisms of protocatechuic acid-induced central analgesia

open access: yesSaudi Pharmaceutical Journal, 2018
It is aimed to investigate the central antinociceptive effect of protocatechuic acid and the involvement of stimulation of opioidergic, serotonin 5-HT2A/2C, α2-adrenergic and muscarinic receptors in protocatechuic acid-induced central analgesia in mice ...
