Pain, 156(12), 2545-2555 (2015-08-27)
The pathophysiology and underlying pain mechanisms of temporomandibular disorders (TMD) are poorly understood. The aims were to assess somatosensory function at the temporomandibular joints (TMJs) and to examine whether conditioned pain modulation (CPM) differs between TMD pain patients (n =

The role of the Na,K-ATPase beta-subunit in stabilization of ion-binding sites has been investigated. Treatment of the purified renal Na,K-ATPase with 0.25 M DTT at 40 degrees C for 1 h resulted in 50% loss of Rb occlusion, which correlates

The fluorogenic sulfhydryl probe 7-diethylamino-3-(4'-maleimidylphenyl)-4-methylcoumarin (CPM) (1-50 nM) is used to characterize the functional role and location of highly reactive thiol groups on the ryanodine-sensitive Ca2+ release channel complex [i.e., ryanodine receptors (RyRs)] of skeletal and cardiac junctional sarcoplasmic reticulum
