  • Publication number: 20240082387
    Abstract: The present invention relates to a fusion protein comprising a SARS-CoV-2-derived receptor-binding domain and a nucleocapsid protein, and the use thereof. The fusion protein comprising a coronavirus-derived receptor-binding domain and a nucleocapsid protein is highly applicable to a multivalent vaccine composition having greatly improved in-vivo half-life and remarkably superior efficacy compared to an immunogenic composition comprising only a receptor-binding domain. In particular, the fusion protein can greatly improve the titer of the coronavirus-specific antibody formation and T-cell immune response, and is thus useful for the prevention and treatment of coronaviruses comprising SARS-CoV-2.

  • Patent number: 7091934
    Abstract: A method and apparatus for controlling address power of a plasma display panel and a plasma display panel device having that apparatus, wherein the plasma display panel includes pluralities of address electrodes, scan electrodes, and sustain electrodes, the scan electrodes and sustain electrodes forming pairs and being alternately disposed. After determining an attenuation coefficient that corresponds to a sum of pixel differences between lines throughout an input video signal, output video data is modified by multiplying the attenuation coefficient to the input video data. According to such a power control of address data, power consumption is reduced since the number of times of switching address data is reduced.
