Abstract: The present invention relates to a channel state transmission method using time domain coefficient quantization. A terminal measures channel information in the time domain and transmits it to a base station. In this instance, a multipath frequency selective fading channel is displayed in a tapped delay line format configured with a per-path path delay value and a path gain in the time domain, differentiates a quantization level for each path gain for more efficient transmission, quantizes the same, and transmits it to a transmitter. Therefore, while the amount of bandwidths required for transmitting state information from the terminal to the base station is reduced, the base station can efficiently acquire channel state information on the entire bandwidths. Also, the base station transmits signals to many terminals through beamforming by using the acquired reliable channel state information, thereby increasing the terminal's signal receiving performance.

Abstract: A method for expressing a recombinant protein from bone marrow-derived cells comprises the steps of treating the bone marrow-derived cells in vitro with a TGF.beta.1 protein, which selects a population of the cells for further treatment. The selected cells can then be expanded, after which a gene encoding a therapeutic protein can be inserted into the expanded cells and thereafter express the therapeutic protein. The transduced cells can then be introduced into a mammal to produce a therapeutic result.

Abstract: Compositions and methods for minimizing or preventing post-surgical adhesion formation between tissue, e.g., organ, surfaces in body cavities, whereby an effective therapeutic amount of anti-asthmatic ketotifen (4-1(1-methyl-4-piperidyliden-4H-benzo?4,5!cyclohepta?1,2-b! thiophene-10 (9H)-one, hydrogen fumarate salt) thereof is administered to the target injury site for a period of time sufficient to permit tissue repair. Ketotifen or analogs thereof is preferably administered in conjunction with a delivery vehicle (e.g., microcapsules, microspheres, biodegradable polymer films, lipid-based delivery systems such as liposomes and lipid foams, crystalloid and viscous instillates and absorbable mechanical barriers) useful for maintaining local concentrations of the inhibitor at the injury site at an effective level for a sustained period of time.
