Compositions and methods for treatment and prevention of disorders and conditions characterized by reduced TGF-\u03b2 signaling are described. The preferred embodiment for predictive text involves the use of weighted positional digrams and a partial word dataset as well as optional elements involving three different types of voice recognition. The second component is formed by injection-molding plastic material onto the connecting section. Each trench further having opposing sidewalls lined with a dielectric layer, and a conductive electrode disposed on at least a portion of the dielectric layer.
