  • Patent number: 5580773
    Abstract: An unprocessed human immunodeficiency virus 2 (HIV-2) gag precursor protein, containing a deficient protease, assembles into virus-like particles by budding through the cytoplasmic domain of baculovirus-infected cells. Chimeric constructs were generated by coupling the truncated HIV-2 gag gene to the neutralizing domain (V3) or the neutralizing and CD4 binding domains (V3+CD4B) of gp120 env gene sequences obtained from HIV-1 or HIV-2. Virus-like particles were formed by chimeric gene products when the env gene sequences were linked to the 3' terminus of the gag gene. The gag-env chimeric proteins displayed immunoreactivity towards anti-gp120 rabbit antisera.

  • Patent number: 5574239
    Abstract: A method of displaying a title and lyrics of the first measure of a reserved song before the end of a currently performed song includes steps for calculating remaining time by comparing total performance time with an elapsed time of a currently performed song, obtaining a title and lyrics information for the first measure of the reserved song responsive to a reserved song number when the remaining time is less than a predetermined value, and displaying the title and the lyrics information superimposed on a background image associated with the currently performed song. The method for displaying title and lyrics information using a video-song accompaniment apparatus enhances user convenience by displaying the title and associated lyrics for the first measure of a reserved song for verification before a currently performed song ends. A video-song accompaniment apparatus capable of performing this method is also described.

  • Patent number: 5194376
    Abstract: A baculovirus expression system capable of producing foreign gene proteins at high levels. The system involves the production of a recombinant baculovirus containing a modified foreign gene between the polyhedrin gene promoter region and the transcription termination signal of the polyhedrin structural gene. The modified foreign gene comprises a putative ribosome binding site immediately upstream of the foreign gene coding sequence, i.e. without any intervening non-coding sequences. The putative ribosome binding site is preferably properly positioned without the intervening sequences by a crossover linker mutagenesis procedure before the modified foreign gene is introduced into the virus. The putative ribosome binding site preferably comprises at least the final four nucleotides of the sequences ACCTATAAAT immediately upstream of the translation inibiation codon (ATG) of the foreign gene.
