Abstract: CD4 mimic compounds having improved efficacy for anti-HIV treatment and more improved pharmacokinetics are provided. The compounds are represented by formula (I): wherein R1 is C2H4(OC2H4)n—OCH3 or CmH2m+1; R2 is O or NH; n is 3 to 25; and m is 4 to 22, or a salt thereof. HIV infection inhibitor compositions including the compound or a salt thereof as an active ingredient are also disclosed.

Abstract: Disclosed is a method for determining kinase activity. The method comprises: (A) mixing a specimen that comprises a kinase, a substrate of the kinase and an adenosine triphosphate (ATP) derivative that comprises a dinitrophenyl (DNP) group to obtain a mixture that comprises a DNP group-containing substrate in which the DNP group is introduced in the substrate; (B) mixing the mixture obtained at the (A) and an antibody that binds to the DNP group to form a complex that comprises the DNP group-containing substrate and the antibody; and (C) determining an activity of the kinase by detecting the complex. The ATP derivative is a compound in which the DNP group is bound to a phosphate group at a gamma position of ATP via a linker.

Abstract: An optical fiber cable network and method of construction of an optical fiber cable network. An optical fiber cable network 100 is provided with an optical fiber cable 10 which has a plurality of optical fiber cores 70a, 70b, and 71 which transmit an optical signal, an optical signal device 50 which is connected to the two ends of the optical fiber cores 70a and 70b among the plurality of optical fiber cores, and two branchers 80a and 80b which are provided at least at one of the optical fiber cores and branching the optical signal, one brancher 80a of the two branchers branching the optical signal from the optical signal device at one end side and the other brancher 80b branching the optical signal from the optical signal device at the other end side.

Abstract: A printer has a feeding path for guiding a printing paper from and toward an opening of the printer. A cross-sectional shape of the feeding path is minimized to be sufficient to pass the printing paper through the feeding path. At least one resonator is arranged in the feeding path. The resonator has a case defining a resonant chamber and holes formed on the case along with the feeding path. The resonant chamber communicates with the feeding path through the holes. Noises such as impact sound generated by a printing head of the printer are silenced by the resonator at frequencies around a resonance fequency of the resonator, and further silenced by the area reduced portion of the feeding path.
