  • Publication number: 20240050538
    Abstract: The present invention relates to a composition for storing a liquid formulation of botulinum toxin for a long period of time at a low temperature and, more specifically, to a liquid-phase pharmaceutical composition and a method for maintaining biological activity of botulinum toxin by using same, wherein the composition comprises, as active ingredients, (i) botulinum toxin, (ii) hyaluronic acid or a pharmaceutically acceptable salt thereof, and (iii) one or more additives selected from the group consisting of saccharides, a non-ionic surfactant, and a stabilizer. The composition according to the present invention has a remarkable effect of physically and chemically stabilizing botulinum toxin and preventing the tertiary structure of botulinum toxin from denaturing, thus making it possible to expand the formulation of botulinum toxin from conventionally limited dry agents to liquid-phase agents.

  • Publication number: 20130089513
    Abstract: Disclosed is a protein variant which substitutes valine for phenylalanine residue in a binding domain having a biological response-modifying function by binding to a receptor, ligand or substrate. Also, the present invention discloses a DNA encoding the protein variant, a recombinant expression vector to which the DNA is operably linked, a host cell transformed or transfected with the recombinant expression vector, and a method of preparing the protein variant comprising cultivating the host cell and isolating the protein variant from the resulting culture. Further, the present invention discloses a pharmaceutical composition comprising the protein variant and a pharmaceutically acceptable carrier.

  • Patent number: RE49923
    Abstract: A multilayer ceramic capacitor includes: a ceramic body including dielectric layers and first and second internal electrodes disposed to face each other with respective dielectric layers interposed therebetween; and first and second external electrodes disposed on an external surface of the ceramic body, wherein the dielectric layer contains a barium titanate-based powder particle having a core-shell structure including a core and a shell around the core, the shell having a structure in which titanium is partially substituted with an element having the same oxidation number as that of the titanium in the barium titanate-based powder particle and having an ionic radius different from that of the titanium in the barium titanate-based powder particle, and the shell covers at least 30% of a surface of the core.
