Coronary intraluminal white clot formation, apparently in response to acetylcholine testing, may explain a woman's long-term history of daily chest pain and multiple myocardial infarctions. Acetylcholine testing reproduced chest pain and revealed luminal filling defects in multiple vessels; imaging showed fresh white platelet clots. Antiplatelet prasugrel has substantially suppressed her symptoms. ().

Learning in dynamic environments requires animals to not only associate cues with outcomes but also to determine cue salience, which modulates how quickly related associations are updated. While dopamine (DA) in the nucleus accumbens core (NAcc) has been implicated in learning associations, the mechanisms of salience are less understood. Here, we tested the hypothesis that acetylcholine (ACh) in the NAcc encodes cue salience.

In the pressing quest of novel treatments for chronic pain, α7 nAChR silent agonists show efficacy as anti-inflammatory modulators and represent a promising strategy. Recent findings reveal that a sulfonium ion can replace the quaternary ammonium nitrogen as an alternative pharmacophore for nAChR silent activation. This study reports the design, synthesis, and electrophysiological evaluation of a new series of sulfonium-based derivatives inspired by the archetypal silent agonist NS6740.

Background: A coronary function test (CFT) is the recommended diagnostic test to identify coronary vasomotor dysfunction as a cause of symptoms in patients with angina and nonobstructive coronary arteries (ANOCA). Acetylcholine is the commonly used pharmacological agent for spasm provocation. We aimed to investigate an association between severity of symptoms and provocative acetylcholine dose.

Alzheimer's disease is a complex neurodegenerative disease characterized by progressive decline in cognitive function and behaviour. Ginger is the rhizome of the plant Zingiber officinale Roscoe, has been an important ingredient of many Ayurveda formulations to treat neurological disorders. The present study aims to estimate the variation of 6-gingerol content in nine different ginger samples collected from Manipur, India, investigate the neuroprotective potential of the most potent ginger sample against scopolamine-induced cognitively impaired mice, and validate the therapeutic claim by molecular docking analysis.
