Abstract: A resin composition containing a polycarbonate resin and a fluorine-containing copolymer. The fluorine-containing copolymer is a copolymer containing a polymerized unit based on tetrafluoroethylene in an amount of 75% by mass or more of all polymerized units and at least one selected from a polymerized unit based on hexafluoropropylene and a polymerized unit based on a perfluoro(alkyl vinyl ether) in an amount of 2% by mass or more. Also disclosed is a molded article formed from the resin composition, the polycarbonate resin constituting a continuous phase and the fluorine-containing copolymer constituting a dispersed phase having an average particle size of 0.01 to 2.5 μm.

Abstract: A communication circuit generates a clock signal that is a digital signal corresponding to a serial clock, and a data signal that is a digital signal corresponding to serial data to be sent. A modulation circuit generates a first modulated signal obtained by digital modulating a first carrier wave having a first frequency with the clock signal and second modulated signal obtained by modulating the second carrier wave having a second frequency different than the first frequency with the data signal, and applies the first modulated signal and the second modulated signal between a first conductor and a second conductor. A demodulation circuit includes a buffer amplifier that has high input impedance, demodulates the first modulated signal and the second modulated signal, and generates the clock signal and the data signal. The communication circuit acquires serial data on the basis of the clock signal and the data signal.

Abstract: The present disclosure relates to a method for producing dental pulp-derived cells enriched with pluripotent stem cells including: (a) digesting dental pulp with a protease to prepare a dental pulp suspension; (b) culturing the suspension to proliferate pluripotent stem cells contained in the suspension; (c) freezing the proliferated pluripotent stem cells in a state in which the pluripotent stem cells are suspended in a first cryopreservation liquid; (d) thawing the frozen pluripotent stem cells; (e) culturing the thawed pluripotent stem cells in a state in which the pluripotent stem cells are adhered to surfaces of particles to proliferate the pluripotent stem cells on the surfaces of the particles; and (f) bringing the particles into contact with a protease to separate the pluripotent stem cells adhered to the surfaces of the particles from the particles.
