(14) Such [Ca2+]i-transients in muscle are actually subcellular spatio-temporal events that are determined dynamically by i) diffusional fluxes of Ca2+, ii) by the binding or unbinding of Ca2+ to ligands such as troponin c and calmodulin, and iii) by the various cellular processes, such as release of Ca2+ from sarcoplasmic reticulum, that produce fluxes of Ca2+ across the membranes bounding organelles or the cell.

(20) Binding and unbinding of MK-801 seems to be possible only if the N-Me-D-Asp-operated channel is in the transmitter-activated state: MK-801 was effective only when applied simultaneously with N-Me-D-Asp, and recovery from MK-801 blockade was speeded by continuous exposure to N-Me-D-Asp [time constant (tau) approximately equal to 90 min at -70 to -80 mV].
Unblind
Definition:
(v. t.) To free from blindness; to give or restore sight to; to open the eyes of.

(8) These results suggest that in double-blind studies, differences in outcome or incidence of adverse drug reactions may act as unblinding factors.
(9) The results of this study differed substantially from previous unblinded studies; therefore, it is suggested that a randomized, double-blind design with simultaneous succinylcholine controls be considered a prerequisite for future studies of intubation conditions.
