Abstract: The present invention relates to compositions and methods for the treatment of hair loss and for promoting hair growth by subcutaneously or intradermally administering injections of compositions comprising therapeutically-effective amounts of extracts of one or more dehydrated human amnion/chorion membrane allografts (“dHACM”) and/or amnionic membrane allografts (“AMA”) suspensions, alone or in combination with one or more extracts of platelet rich plasma (“PRP”), wherein the dHACM and/or AMA suspensions are administered in therapeutic dosages and in a composition for use in the disclosed method.

Abstract: MBE growth of epitaxial layers on selected areas of a growth surface (e.g., wafer or epi-layer grown thereon) is achieved by masking portions of the surface with an amorphous material and directing molecular beams at the masked surface so that a polycrystalline layer deposits on the mask and an epi-layer grows in the unmasked zones. The mask material is then exposed to a suitable etchant effective to dissolve that material, lift-off the polycrystalline layer and expose the underlying surface. Self-aligned contacts can be fabricated by depositing a metal layer prior to etching. Subsequent lift-off removes both the polycrystalline layer and the overlying metal. This process can be utilized in the fabrication of FETs and opto-electronic devices such as double heterostructure junction lasers.

Abstract: An integrated high-power gallium arsenide field-effect-transistor device for operation in the gigahertz range comprises a multiple-gate structure. The device, which features gate cross-under fingers, is fabricated in microminiature form by directly processing a wafer using electron-beam lithographic techniques.
