  • Publication number: 20230220331
    Abstract: Provided is a temporary treatment medium for inhibiting embryo developmental arrest due to manipulation of an embryo or the like. A temporary treatment medium according to the present invention reduces damage to an in-vitro culture due to manipulation thereof, said in-vitro culture containing one of pluripotent stem cells, reproductive cells, a fertilized egg, and an embryo or any combination thereof. For this purpose, the temporary treatment medium contains a cytoskeleton regulator and/or an apoptosis inhibitor. The cytoskeleton regulator and/or the apoptosis inhibitor is preferably an Rho kinase inhibitor. Specifically, a Rock inhibitor can be used as the Rho kinase inhibitor. The Rock inhibitor is, for example, Y-27632. The temporary treatment medium is used for treating an in-vitro culture for a specific period before and/or after manipulation involving damage thereto.

  • Patent number: 7341740
    Abstract: The invention of the present application provides an isolated and purified human mitochondrial protein comprising the amino acid sequence of SEQ ID NO: 2 or SEQ ID NO: 4, which is a novel human protein promoting aggregation and fusion of mitochondria. The present invention also provides a polynucleotide encoding such a mitochondrial protein, antibody against such a mitochondrial protein, and a proteoliposome composed of such a mitochondrial protein and lipid. Mitochondrial proteins are useful for clarifying causes of mitochondrial diseases as well as for developing preventive and therapeutic methods thereof. Furthermore, antibodies and probes derived from genes encoding such proteins are potentially useful materials for diagnosis of condition of mitochondria in particular diseases. Furthermore, proteoliposomes provide measures for specific transfer of foreign genes or drugs targeted toward mitochondria.

  • Patent number: 7319881
    Abstract: An example information delivering device includes a conversation relaying section for relaying conversation data between users of two or more information terminals. The conversation data corresponds to a conversation between the respective users of the information terminals. An additional information delivering section adds audio data such as advertisements and music to the conversation data so that the audio data and the conversation data can be reproduced simultaneously by one or more of the information terminals, while the conversation relaying section relays the conversation data between the information terminals. This allows the information delivering device to deliver additional information such as advertisements and music during a telephone conversation.

  • Patent number: 7181340
    Abstract: An engine control circuit includes a battery voltage detector, a signal supervisor, and a processor that operates in a normal mode and a power-down mode. The battery voltage detector senses the output voltage of a battery that supplies current to the engine, and asserts a detection signal when the voltage is below a predetermined value. The signal supervisor measures the length of time for which the detection signal remains asserted. The processor switches from the normal mode to the power-down mode when the measured length of time reaches a predetermined value. This scheme avoids loss of engine control when the battery voltage drops briefly and then recovers.

  • Patent number: 6988046
    Abstract: In a test method of a memory IC function, memory ICs of different types are prepared after a memory tester is prepared. The data related to each test method of these memory ICs is transmitted to the memory tester. Further, after a random number is generated, a test of a predetermined memory IC is executed in reply to the generated random number. It is checked whether the tests of all the memory ICs are finished or not: and the generation of the random number and the execution of the test are repeated when they are not finished, while the processing is finished when they are finished.

    Abstract: A system LSI dynamically and speedily controls clocks of various frequencies as used in a wide range of operation modes from high-speed to low-speed operation modes, enabling user selection of a system of power consumption type most suitable. The system LSI includes a ROM that stores a clock control library for carrying out clock state transitions between ordinary operation modes; and a system control circuit having a register for carrying out clock state transitions between ordinary operation modes and special modes responsive to changes in value of the register, and also carrying out clock state transitions among ordinary operation modes responsive to the clock control library. Calling of the clock control library and changing of the register value are controlled by an application program. The main library of the clock control library is described and called using C language.
