A programming-device user interface may include multiple levels of abstraction for programming treatment settings. Magnification is changed by moving the first lens group and the second lens group. One end of the hitch member is attached to one of the vehicle body, the vehicle seat fixed to the vehicle body, or the seat weight sensor fixed to the vehicle body. A passageway allows for communication between the forward passenger area and the rearward passenger area. In one aspect, the invention is directed to novel homologs of bcl-2 designated CDN-1, CDN-2, and CDN-3, and fragments, variants, homologs and derivatives thereof, which are capable of modulating apoptosis. Furthermore, the stereoscopic image-taking lens apparatus sends a signal for inhibiting an image-taking operation in which the charge-storage time of the image-pickup element is longer than the predetermined time for changing over the shutter to the image-taking apparatus.
