Role of Phenylethanolamine-N-methyltransferase on Nicotine-Induced Vasodilation in Rat Cerebral Arteries.

Objective: The sympathetic-parasympathetic (or axo-axonal) interaction mechanism mediated that neurogenic relaxation, which was dependent on norepinephrine (NE) releases from sympathetic nerve terminal and acts on β-adrenoceptor of parasympathetic nerve terminal, has been reported. As NE is a weak β-adrenoceptor agonist, there is a possibility that synaptic NE is converted to epinephrine by phenylethanolamine-N-methyltransferase (PNMT) and then acts on the β-adrenoceptors to induce neurogenic vasodilation.

Methods: Blood vessel myography technique was used to measure relaxation and contraction responses of isolated basilar arterial rings of rats.

Effectiveness of various treatment modalities in children with vesicoureteral reflux grades II-IV: a systematic review and network meta-analysis.

Hydrogen Protons Modulate Perivascular Axo-axonal Interactions in the Middle Cerebral Artery of Rats.

Previous studies have demonstrated that nicotine can induce relaxation of the middle cerebral artery (MCA). However, whether this relaxation is associated with the activity of sensory calcitonin gene-related peptide (CGRP) nerves and whether this is modulated by hydrogen protons (H), facilitating the release of CGRP from sensory CGRPergic nerve terminals in the MCA, remains unclear. In this study, we examined the role of H in the modulation of neurogenic vasomotor responses in the rat-isolated endothelium-denuded MCA.

The aging effects on phenylephrine-induced relaxation of bladder in mice.

Objective: We have demonstrated that phenylephrine (PE) activates the capsaicin-sensitive nerves, and then activates capsaicin-sensitive nerves to release an unknown substance that facilitates the release of norepinephrine (NE) from adrenergic nerves. Subsequently, NE stimulates β-ARs in the detrusor muscle in mice, leading to neurogenic relaxation of the urinary bladder (UB).

Materials And Methods: We examined if there existed sensory-motor dysfunction in UB of aging mice.

Comparing the Efficacy of OnabotulinumtoxinA, Sacral Neuromodulation, and Peripheral Tibial Nerve Stimulation as Third Line Treatment for the Management of Overactive Bladder Symptoms in Adults: Systematic Review and Network Meta-Analysis.

The American Urological Association guidelines for the management of non-neurogenic overactive bladder (OAB) recommend the use of OnabotulinumtoxinA, sacral neuromodulation (SNM), and peripheral tibial nerve stimulation (PTNS) as third line treatment options with no treatment hierarchy. The current study used network meta-analysis to compare the efficacy of these three modalities for managing adult OAB syndrome. We performed systematic literature searches of several databases from January 1995 to September 2019 with language restricted to English.
