RETRACTION.

abstract：BACKGROUND AND PURPOSE:In the ciliary muscle, the tonic component of the contraction produced by cholinergic agonists is highly dependent on Ca2+ provided by influx through non-selective cation channels (NSCCs) opened by stimulation of M3 muscarinic receptors. We examined effects of YM-254890 (YM), a Gq/11-specific inh...
