The present invention relates to methods of using cocaine-binding-site ligands and cocaine-binding-site RNA aptamers to treat or prevent Alzheimer’s Disease and to reduce or prevent aggregation of beta-amyloid peptides in a subject. A tube, or bundle of tubes, is placed in the cleaning receptacle, extending through an inlet port from the vertical receptacle, and a gate is closed to clamp the tubes in place. The backlight assembly includes a reflecting sheet having a raised portion that receives a light source and supports a diffusing sheet andor optical sheet positioned between the liquid crystal panel and the light source. In response to the signals, the wireless controller sets control settings for operating one or more of a variety of equipment types, such as a furnace, air conditioner, water heater or heat pump.
