  • Publication number: 20210030823
    Abstract: According to a conventional method for treatment of Sandhoff disease and Tay-Sachs disease comprising administering a modified ?-subunit to a patient in the form of a protein, it is necessary that administration be performed frequently. This invention relates to a recombinant adeno-associated virus virion comprising: capsomere comprising a protein capable of forming a virus virion; and a polynucleotide packaged in the capsomere comprising a promoter sequence and nucleotide sequences operably linked to the promoter sequence encoding a first amino acid sequence derived from the amino acid sequence of the ?-subunit of wild-type human ?-hexosaminidase composed of amino acids 55 to 556 in the sequence as shown in SEQ ID NO: 28 by substitution of amino acids 312 to 318 with glycine, serine, glutamic acid, proline, serine, glycine, and threonine in that order and a second amino acid sequence, which is an amino acid sequence of a signal peptide linked to the N terminus of the first amino acid.

  • Patent number: 7082201
    Abstract: A three-dimensional sound reproducing apparatus is configured by cascading a sound field effect adding unit and a crosstalk canceling unit. The sound field effect adding unit adds a predetermined three-dimensional sound field effect to an input audio signal, thereby generating audio signals respectively corresponding to left and right channels. The crosstalk canceling unit performs a calculation process on the audio signals of the two channels so that, when the audio signals are respectively generated by two loudspeakers positioned in front of a listener, the audio signals reach the left and right ears of the listener without producing crosstalk. The resulting audio signals are supplied to the loudspeakers, respectively.

  • Patent number: 6468841
    Abstract: At least a part of the surface of a crystalline silicon semiconductor substrate is rendered porous to convert at least a part of the crystalline silicon semiconductor substrate to a porous silicon layer. A catalytic metal layer is formed on the porous silicon layer. An amorphous silicon thin film is formed on the catalytic metal layer. The amorphous silicon thin film is heated to monocrystallize the amorphous silicon thin film, thereby converting the amorphous silicon thin film to a crystalline silicon thin film. The crystalline silicon semiconductor substrate, provided with the crystalline silicon thin film, is joined to a support substrate so that the crystalline silicon thin film faces the support substrate. The crystalline silicon semiconductor substrate, together with the porous silicon layer, which is the crystalline silicon semiconductor substrate in its portion converted to a porous layer, is separated and removed from the crystalline silicon thin film joined to the support substrate.
