Publication number: 20090324610Abstract: Two genes implicated in arteriosclerotic diseases such as cerebral infarction were successfully identified by performing genome-wide correlation studies using SNPs by targeting the entire genome. Polymorphic mutations that can be used to examine the presence or absence of risk factors for arteriosclerotic diseases were successfully found on the genes. Subjects can be efficiently examined for the presence or absence of risk factors for arteriosclerotic diseases using the presence or absence of the polymorphic mutations as indicators. Furthermore, methods of screening for therapeutic agents for arteriosclerotic diseases are enabled by using expression or function of the genes as index.Type: ApplicationFiled: April 24, 2007Publication date: December 31, 2009Applicants: KYUSHU UNIVERISTY, NATIONAL UNIVERSITY CORPORATION, THE UNIVERSITY TOKYO, HISAYAMA RESEARCH INSTITUTE FOR LIFESTYLE DISEASES, NTT DATA CORPORATION, HUBIT GENOMIX, INCInventors: Yutaka Kiyohara, Mitsuo Iida, Setsuro Ibayashi, Michiaki Kubo, Jun Hata, Yusuke Nakamura, Teruo Omae, Yasuhiro Tanaka, Go Ichien

Patent number: 6377692Abstract: Two keys which are updated in the same updating cycle at different times are prepared as signature keys (main key and auxiliary key) for electronic signature, and the updating cycle of each key is divided into, for example, three periods. The first and last periods after the updating are used for the auxiliary key while the intermediate period is used for the main key, and an electronic signature is carried out with the main key. The electronic signature is confirmed with either of two confirmation keys which are updated synchronously with updating the two keys used as the signature keys. This eliminates the need of stopping issuance of the electronic signature or limiting a service offer upon updating the signature keys.Type: GrantFiled: March 11, 1999Date of Patent: April 23, 2002Assignees: NTT Data Corporation, Nippon Telegraph and Telephone CorporationInventors: Yoshio Takahashi, Hidemi Moribatake

Patent number: 6260027Abstract: A collecting agency supplies a collecting agency name and a money bag number to a service providing terminal. In response to dealing requests from user terminals, the service providing terminal sends, to the user terminals, information which contains the collecting agency name (Id) and the money bag number (Gb) supplied from the collecting agency. The user terminals generate digital signatures containing the received request information, affix the generated signatures to electronic tickets to be used, and send the electronic tickets with the signatures to the service providing terminal. The service providing terminal, which has received the used electronic tickets, collects those electronic tickets which include the same money bag number supplied from the collecting agency into a group (a money bag), and sends the group of electronic tickets to the collecting agency.Type: GrantFiled: October 20, 1998Date of Patent: July 10, 2001Assignees: NTT Data Corporation, Nippon Telegraph & Telephone CorporationInventors: Yoshio Takahashi, Hidemi Moribatake
