The present invention relates to a method of identifying a compound which blocks the activation of a stress-activated protein kinase selected from the group consisting of SAPK4 and SAPK3 by SKK3. Each of the planetary gear sets includes first, second and third members. Further, the ring switch includes at least one local port that is coupleable to at least one local area network. The compositions are best applied using a small pump-spray bottle having a relatively small output aperture. The outer member can slide relative to the tubular member in an axial direction. An improved method for integration of different menu items relating to on-disc content and downloaded content provides flexibility and a simple, low cost solution.
