Abstract: A rapid method for preparing stem cell and physiologically acceptable matrix compositions for use in tissue and organ repair is described. Compared with previous tissue engineering materials, the stem cell-matrix compositions of the present invention do not require long-term incubation or cultivation in vitro prior to use in in vivo applications. The stem cells can be from numerous sources and may be homogeneous, heterogeneous, autologous, and/or allogeneic in the matrix material. The stem cell-matrix compositions provide point of service utility for the practitioner, wherein the stem cells and matrix can be combined not long before use, thereby alleviating costly and lengthy manufacturing procedures. In addition, the stem cells offer unique structural properties to the matrix composition which improves outcome and healing after use. Use of stem cells obtained from muscle affords contractility to the matrix composition.

Abstract: The present invention provides apparatus and an associated method for remotely energizing power storage devices. Energization may preferably be effected through the use of RF energy from a base station, ambient energy or ultra-wide band energy. The remote station preferably has at least one antenna having an effective area greater than its physical area. The system may have an antenna and associated circuitry provided on an electronic chip such as a monolithic chip or on a printed circuit with a suitable substrate.

Abstract: The present invention relates to new silver-ion super-complex compositions. More particularly, the present invention describes silver-ion super-complex compositions comprising a silver-thiosulfate ion complex further complex with a primary, secondary or tertiary amine. These silver-ion super-complex compositions are stable in a saline environment and have improved solvent miscibility.

Abstract: A nano-optic device comprises a plurality of subwavelength apertures in a metal film or between metal islands. The device is adapted to shape a radiation beam transmitted there through. For example, beam shaping includes at least one of beam focusing, beam bending and beam collimating.

Abstract: A station having a means for receipt of ambient energy from the environment and energizing power storage devices of objects of interest comprising one or more antennae and circuitry for converting said ambient energy into DC power for energizing said power storage devices. The circuitry for converting the ambient energy into DC power may include a rectifier/charge pump. The antenna of the station is tuned to maximize DC energy at the output of the rectifier/charge pump. The station can be used to energize power storage devices including capacitors and batteries that are used in electronic devices, such as cell phones, cameras, PDAs. Various antenna constructions may be employed.

Abstract: A process to produce N-vinylformamide includes the steps of: reacting hydroxyethyl formamide with a reactant comprising at least one cyclic anhydride group to form an ester, and dissociating the ester via heat in a thin film evaporation to synthesize N-vinylformamide and a compound comprising at least one diacid group, the N-vinylformamide separating from the diacid during the thin film evaporation. The reactant including at least one cyclic anhydride group can, for example, be succinic anhydride, maleic anhydride, phthalic anhydride, (2-docecen-1-yl)succinic anhydride, exo-3,6-epoxy-1,2,3,6 -tetrahydrophthalic anhydride or a polymer including at least one cyclic anhydride group.

Abstract: A wireless untethered device which may be an integrated circuit chip or printed circuit board having at least one integrated antenna and circuitry operatively associated with the antenna for receipt of energy harvested from space by the antenna. The antenna has an effective area greater than its physical area. A system which receives power from the harvested energy after the energy is processed by the circuitry may also be provided with mismatched impedance between the antenna and a circuit resistance.

Abstract: The present invention relates to novel stabilized silver ion complexes having improved stability in aqueous solutions. The described stabilized silver-ion complex compositions comprise a silver-thiosulfate ion complex, a sulfite stabilizing agent either with or without a sulfite preservation agent. These carrier-free aqueous sulfite stabilized silver thiosulfate ion complex compositions have improved stability when exposed to an aqueous environment for extended periods. Consequently, these compositions have improved antibacterial, anti-viral and/or antifungal activity. These stabilized compositions can be used to coat a wound dressing, an ostomy appliance, an incontinence device, or other medical devices and impart long-term antimicrobial activity.
