Spinal disc therapy systems in accordance with the present invention generally include an implant element structured to have a therapeutic effect on a human or animal body when implanted into an intervertebral disc annulus or intervertebral disc nucleus. A termination circuit is connected internal to the integrated circuit to the input of a differential receiver in parallel with a transmission line connectable to the receiver. The gain section includes a gain medium with having a superstructure grating forming a distributed Fabry-Perot-like structure. The brewing plunger is hydraulically guided displaceably in the holder relative to the holder. Pharmaceutical salts, formulations, and methods of using the same in the treatment of cancer are also described.
