  • Publication number: 20230407249
    Abstract: Provided are media and methods for establishing and maintaining mammalian early embryo-like cells. The culture media can be used to culture mammalian pluripotent stem cells (PSCs), which is chemically defined and comprises basal media for culturing stem cells supplemented with a S-adenosylhomocysteine hydrolase (SAH)/Polycomb repressive complexes (PRC)/EZH2 inhibitor, a histone deacetylase (HDAC) inhibitor and a WNT/?-catenin signaling/tankyrase inhibitor. With the culture media, primate (human and non-human) PSCs can be converted to preimplantation ICM-like cells (ICLCs) or 8-cell embryo-like cells (8CLCs).

  • Patent number: 9947857
    Abstract: The present invention provides a polymeric actuator which has excellent flexibility and elongation rate; low temperature dependability of physical properties such as an elastic modulus and high dielectric breakdown strength, and which can drive in a low electric field. The present invention relates to a polymeric actuator, wherein the polymeric dielectric has a storage elastic modulus at 20° C. [E?(20° C.)] determined by a dynamic viscoelastic measurement at a frequency of 1 Hz of not more than 0.5 MPa, a ratio [E?(?20° C.)/E?(20° C.)] of a storage elastic modulus at ?20° C. [E?(?20° C.)] determined by a dynamic viscoelastic measurement at a frequency of 1 Hz to the [E?(20° C.)] of not more than 5.0, and a ratio [E?(40° C.)/E?(20° C.)] of a storage elastic modulus at 40° C. [E?(40° C.)] determined by a dynamic viscoelastic measurement at a frequency of 1 Hz to the [E?(20° C.)] of not less than 0.5.

  • Patent number: 9745436
    Abstract: The present invention provides a sensor having an improved sensitivity and precision, which is lighter and more flexible than conventional sensors, and a method of making the sensor. The present invention relates to a sensor comprising a resin foam containing a magnetic filler, and a magnetic sensor that detects a magnetic change caused by a deformation of the resin foam, wherein the resin foam is a polyurethane resin foam that comprises a polyisocyanate component, an active hydrogen component, a catalyst and a foam stabilizer, and wherein the resin foam has a hardness change (H1-H60) of 0 to 10 between a JIS-C hardness (H1) in one second after contact with a pressure surface of a hardness tester and a JIS-C hardness (H60) in 60 seconds after the contact.
