A device for testing printed circuit boards that have contact points arranged in a pattern. The invention includes a pair of panels, each sized to conceal a portion of the track, and a pair of brackets each having a first portion attachable to the track and a second portion configured to support an edge of a corresponding panel. The invention provides novel MUC5B promoter sequences and reporter constructs comprising these MUC5B promoter sequences. Adjustment means are provided for increasing the intensity characteristic of the light that reaches the detector to account for a decrease in intensity that occurs when the lens is in the path of the light beam to spread the beam. , for administering a donepezil active agent to a subject, and kits containing the formulations.
