  • Publication number: 20250082209
    Abstract: A biological information measurement device includes a pulse acquisition mechanism configured to detect a pulse of a human body, a pulse interval calculation mechanism configured to calculate, based on the pulse, a pulse interval between one beat and a beat immediately before the one beat, and a display mechanism configured to display a level indicator visually indicating at least one of the pulse interval or an amount of change from another pulse interval immediately before the pulse interval. The level indicator indicates, per beat of the pulse detected, the pulse interval or the amount of change.

  • Publication number: 20250053920
    Abstract: An analysis system includes: an analyzer that performs an analysis using polymer filled in a polymer cartridge, acquires attribute information on the polymer cartridge, and transmits the attribute information to the outside; and a server that acquires the attribute information on the polymer cartridge transmitted from the analyzer, collates the attribute information with attribute information stored in a database, and transmits to the analyzer a determination result obtained by determining whether or not the polymer cartridge in which polymer corresponding to the collated attribute information has been filled already is proper as an object to be set on the analyzer.

  • Publication number: 20250026854
    Abstract: The present inventors produced a variety of bispecific antibodies that specifically bind to both F. IX/F. IXa and F. X, and functionally substitute for F. VIIIa, i.e., have a cofactor function to promote F. X activation via F. IXa. Among these antibodies, the antibody A44/B26 reduced coagulation time by 50 seconds or more as compared to that observed when the antibody was not added. The present inventors produced a commonly shared L chain antibody from this antibody using L chains of A44, and showed that A44L can be used as commonly shared L chains, although the activity of the resulting antibody is reduced compared to the original antibody (A44HL-B26HL). Further, with appropriate CDR shuffling, the present inventors successfully produced highly active multispecific antibodies that functionally substitute for coagulation factor VIII.
