alpha(1)-Adrenoceptor has been discovered to exist in many human tissues and mediates important physiological functions. The purpose of this study was to detect the expression, distribution, and function of alpha(1)-adrenoceptor subtypes in human submandibular glands. alpha(1A)- and alpha(1B)-Adrenoceptor mRNAs were

The most common preclinical models of neuropathic pain involve surgical ligation of sensory nerves, which is especially difficult in mice. Transient models of chemically sensitized allodynia are potentially useful for rapidly characterizing the analgesic profile of compounds and conducting mechanistic
