Abstract: The present invention provides a composition for suppressing the expression of the CKAP5 gene, the composition comprising a lipid particle containing a double-stranded nucleic acid as a drug and a cationic lipid, the double-stranded nucleic acid having an antisense strand having a base sequence complementary to the sequence of at least 19 continuous bases in CKAP5 gene mRNA of any one of SEQ ID NOs: 1 to 6, the cationic lipid being represented by formula (I): wherein R1 and R2 are the same or different and are each linear or branched alkyl, alkenyl or alkynyl of 12 to 24 carbon atoms; L1 and L2 are the same or different and are each —CO—O— or —O—CO—; a and b are the same or different and are each 1 to 3; and R3 is a hydrogen atom, alkyl of 1 to 6 carbon atoms, or alkenyl of 3 to 6 carbon atoms; a medicament comprising the composition, and the like.

Abstract: In a DVR recording apparatus, a program and EPG data are received, and the EPG data and a reservation list, which relates to a reservation status of program recording, are stored. In addition, reserved recording, for recording a program in accordance with the reservation list, is carried out. Further, in the DVR, EPG data or the reservation list is transmitted in accordance with a request from a portable telephone. On one hand, in the portable telephone, in accordance with an operation of a user, a request of the EPG data or reservation list is transmitted, and in accordance with the request, the EPG data or reservation list transmitted from the DVR is received. Then, the EPG data or reservation list is presented in the portable telephone to a user.

Abstract: An information processing apparatus, that obtains pieces of content information relating to content recorded in an information recording medium, includes a content identifier generation unit configured to read a content certificate which is recorded in the recording medium and which corresponds to the content stored in the information recording medium, and generates a content identifier by combining hash values which correspond to the content and which are included in data stored in the content certificate, a data transmitting unit configured to transmit the content identifier generated using the content identifier generation unit to a content information provision server, a data receiving unit configured to receive, from the content information provision server, the pieces of content information relating to the content which is specified on the basis of the content identifier, and a data outputting unit configured to output the pieces of content information received using the data receiving unit.

Abstract: A file storage apparatus provides an information management method. The information management method includes correlating one or more electronic files with audible cues relative to audio content reproduced via the file storage apparatus, designating respective time intervals of the audio content during which each of the one or more electronic files can be accessed by the file storage apparatus, and retrieving the one or more electronic files of the file storage apparatus upon a predetermined user input provided to the file storage apparatus during one of the respective time intervals of the audio content.

Abstract: To allow desired information to be easily retrieved from various types of information. Information is registered at a music playing position of music data. Music data that are audio data or MIDI data are played. While music data are being played, registration instruction is issued for example with a keyboard. Information is registered at a music playing position corresponding to timing of issuance of the registration instruction. When information is retrieved, music data to which the information had been registered are played. When the music data have come to the music playing position at which desired information has been registered, a retrieval instruction is issued for example with the keyboard. Based on this instruction, information registered at the music playing position is retrieved. As a result, the information can be accessed. Since information is registered to a music playing position of the music data, information can be easily and intuitionally registered and retrieved.
