Object To maintain perspective consistency among individual objects in an image in superimposition display of a caption in an ARIB method. Preferably the hose is mounted inside a housing to assist in attaching it to a high pressure source and a sleeve slidable about the housing aids in adjusting the tensile connector. Such signal crosstalk products include those resulting from dense wavelength-division mutiplexing of the data signals used to provide the multiplexed data signals, four-wave mixing among the multiplexed data signals within the signal transmission medium, and cross-phase modulation among the multiplexed data signals within the signal transmission medium. The piston is accordingly axially tensioned between two springs. The present invention also relates to the use of steroid analogues, and in particular analogues of 5-androstene-3-, 17-diol, and its epimer 5-androstene-3-, 17-diol for the treatment and prevention of cancer.
