Intracoronary provocation testing with acetylcholine (ACh) is helpful to diagnose and risk‐stratify patients with ischemia with nonobstructed coronary arteries (NOCA) and myocardial infarction with ...

Introduction Studies on human patellar and Achilles tendons have shown that tendon cells not only have the capacity to produce acetylcholine (ACh) but also express muscarinic ACh receptors (mAChRs), ...

How animals flexibly respond to and learn from changes in the environment is an enduring question in neuroscience. An influential theory is that coordinated release of dopamine (DA) and acetylcholine ...

People with pulmonary hypertension (PH) and high blood acetylcholine (ACh) levels show more severe symptoms and a poorer prognosis than those with lower ACh levels, a single-center study in China ...

Medically reviewed by Elizabeth Barnes, RDN Herbs and spices have been used by people around the world since ancient times for both culinary and medicinal purposes. In addition to adding flavor and ...

Acetylcholine (ACh) is a neuromodulator with a central role in aversive learning - rapid conditioning to unpleasant smell, taste, or touch. These learning functions play out in cells called D2 ...

Researchers identify how acetylcholine sets off a signal cascade in brain cells that directly influence aversive learning and memory formation. Patients with Alzheimer's disease (AD) have lower levels ...

Patients with Alzheimer’s disease (AD) have lower levels of the neuromodulator acetylcholine (ACh) in their brains. Donepezil, an AD drug, increases brain ACh levels and improves AD-associated ...

Acetylcholine (ACh) rechallenge may be a novel method to improve detection of coexisting coronary spasm endotypes, and at the same time, assess the treatment response to nitrate-based therapies, a new ...
