  • Publication number: 20050090927
    Abstract: According to the present invention, as processing apparatus drive starts, the operating state of software used to drive the processing apparatus is monitored in real time to diagnose whether or not an abnormality has occurred (S110). If it is judged through the diagnosis performed in S110 that no abnormality has occurred, the workpiece processing is allowed to continue uninterrupted and then a decision is made as to whether or not the workpiece processing has been completed (S130). If the processing has been completed, the processing apparatus is stopped (S140). If, on the other hand, it is judged through the diagnosis performed in S110 that an abnormality has occurred, a log of the diagnosis item with regard to which the abnormality has occurred is recorded (S120). The processing apparatus is then stopped (S140).

  • Publication number: 20050042730
    Abstract: A system in which a ligand is formed by the expression of a polypeptide that converts a ligand precursor into a ligand, and the ligand thus formed binds to a nuclear receptor to thereby induce the expression of a reporter gene located downstream of the target sequence is constructed. Searching a gene library using this system can isolate a gene encoding a polypeptide capable of converting a ligand precursor into a ligand. This system, which takes the advantage of the transcriptional regulatory function of a nuclear receptor, enables screening a ligand that binds to a nuclear receptor and to examine whether or not a test compound is a ligand that binds to the nuclear receptor, and also screening genes that encode polypeptides capable of converting an inactive form of a wide range of transcriptional regulatory factors into an active form.

  • Patent number: 6632939
    Abstract: The present invention relates to dextran whose boron content is reduced to a value less than 0.30 &mgr;g/g (dry basis) calculated on the basis of boron atom, a process for producing the same, and dextran with which a container is filled in a solution state. Dextran of the present invention is obtained by treating a boron-containing dextran with a lower alcohol, and said dextran has such a characteristic that deposition is inhibited or the deposition rate is drastically reduced when using it in the form of a solution. Therefore, an isotonic sodium chloride solution of said dextran is suitably used as substitute plasma or external perfusate in an operation.

  • Publication number: 20030175817
    Abstract: A novel action mechanism wherein androgen receptor (AR) is activated by the interaction between cyclin E and the androgen receptor was revealed. This activation is resistant to existing anti-androgen agents and both androgen receptor ligand-dependent and independent activations were found to participate in this mechanism. Methods of screening for anti-androgen agents using cyclin E are also provided by the present invention. Based on the findings as described above, novel anti-androgen agents can be screened. These anti-androgen agents are expected to be efficacious also against pathological conditions that have become resistant to existing anti-androgen agents. Thus, the instant invention opens up new possibilities for treatment using anti-androgen agents that had their limitations until now.
