Novel phosphino-gold compounds, a process for their preparation, pharmaceutical compositions containing such phosphino-gold compounds and their use in the treatment of cancer disease are disclosed. The first set of fingers extend axially from the annulus in one direction and the second set of fingers extending axially from the annulus in another direction generally opposite the direction of the first set of fingers. The bipolar transistor may also include at least one other predetermined portion. Also described are methods for treating a prolapsed valve including the steps of securing a first anchor to cardiac tissue located below the prolapsed mitral valve leaflet, securing a second anchor to the prolapsed mitral valve leaflet, tensioning a cord connecting the two anchors and securing the cord. As a result, a received signal obtained on the receiver side has a small level difference between the high frequency signal components and low frequency signal components. The cantilever plates provide force to extend one portion of the key strips from the receiving groove.
