We report for the first time that pterostilbene, a natural analog of resveratrol, shows anxiolytic-like action by downregulating phosphorylated levels of ERKs in the hippocampus of mice. Gamma photons are acquired at a detector. The system according to certain embodiments reads a previously stored signature value corresponding to a respective data block for sending from a backup storage system having at least one memory device to a secondary storage system. The outer surface of the substrate protection plate has a first auxiliary attachment portion formed thereon, to which a first auxiliary circuit board different from the control circuit board and mounted with a highly frequently accessed control element is attached. Accordingly, the incident light flux is made substantially constant among all the reflective elements, and hence the brightness of the light emitted by the lamp is made uniform. A fast OGC transform may be applied to the sampled output of the CMF if OGC sequences are used as signature sequences.
