Abstract: An expression vector cDNA library derived from senescent cells has been used to isolate cDNA clones that encode inhibitors of DNA synthesis. Such inhibitors play a role in cellular senescence and aging. Antisense nucleic acids reduce the inhibition of DNA synthesis.

Abstract: An apparatus for restricting movement of a device inside a vehicle having a mounting surface therein, wherein the device has a first part and a second part. The apparatus comprising: a holder comprising a support having a first part and a second part; a first receptacle connected to the first part of the support and moveable between a first position and a second position, the first receptacle for receiving the first part of the device when in the first position; and a second receptacle connected to said second part of the support for receiving the second part of the device when the first receptacle is in the second position so that the device is secured by said holder; and a fastener connected to the holder for fastening the holder to the mounting surface of the vehicle so that movement of the device is restricted.
