  • Publication number: 20140199303
    Abstract: The present invention relates to a stable liquid formulation of etanercept (recombinant p75 sTNFR:Fc fusion protein), and more particularly, to a liquid formulation comprising one or more stabilizers selected from the group consisting of methionine, lysine, histidine, and pharmaceutically acceptable salts thereof in an amount sufficient to reduce by-product formation of etanercept during storage. The liquid formulation according to the present invention effectively reduces production of etanercept by-products and to stably maintain its pharmaceutical efficacies for long-term storage. Therefore, the reconstitution procedure is not required before administration, and the sterile formulation can be administered to patients to ensure patient safety. Thus, it can be applied to the fields in need of etanercept treatment.

  • Publication number: 20010008575
    Abstract: An apparatus for searching an image of an image recording and reproducing device in which input data streams received from various signal sources are processed and accordingly generated image and audio signals are outputted to an image displayer and a speaker, includes: a data stream selector for receiving the input data streams, selecting and outputting an input data stream of a channel selected by a user; a decoding unit for decoding the data stream outputted from the data stream selector; a formatter for receiving the data stream from the data stream selector, converting it to a record signal, outputting the record signal to a recording medium, detecting the signal recorded in the recording medium, generating a reproduction signal, and outputting the reproduction signal to the data stream selector; a controller for judging whether there is a data stream having an I picture among the input data stream outputted from the data stream selector, a memory associated with the selected input data stream recorded i
