  • Publication number: 20070156096
    Abstract: To provide a puncture device in which a puncture needle is stuck into a predetermined region certainly and an indwelling device can be indwelled, the puncture device is provided for puncturing skin (dermis) by a puncture needle. This puncture device is provided with a puncture needle, an indwelling device indwelled in the skin by the puncture needle, a skin deforming mechanism for deforming the skin which is provided with a fixing portion having a space in an inside constituted by a bottom face portion and a peripheral wall portion 5b. In addition, an insertion portion for inserting the puncture needle is formed at the peripheral wall portion, the puncture needle is inserted from the insertion portion, and the skin deformed into the space by the skin deforming mechanism is adapted to be punctured.

  • Patent number: 7193078
    Abstract: Disclosed herein is a process for production of an O-alkylrapamycin derivative represented by the general formula (1) below by reaction between rapamycin and alkyl triflate in an organic solvent, characterized in that the reaction is carried out in the presence of trialkylamine. (where R denotes alkyl, arylalkyl, hydroxyalkyl, alkoxyalkyl, acyloxyalkyl, aminoalkyl, alkylaminoalkyl, alkoxycarbonylaminoalkyl, acylaminoalkyl, or aryl.) This process is capable of producing O-alkylrapamycin derivative efficiently owing to improvement in reaction yields for O-alkylation.

  • Publication number: 20060223189
    Abstract: The present invention provides solid-phase saccharide dyes. The dyes are bisboronic acids covalently bonded to a solid substrate. The dyes selectively conjugate with saccharides, particularly glucose, and register a signal. The signal is proportional to the quantity of saccharide. Thus, the dyes of the present invention are useful for measuring and monitoring saccharide levels, particularly in biological fluids such as blood.

  • Publication number: 20050221277
    Abstract: An intracorporeal substance measuring assembly to be provided in an embedded-type substance sensor for detecting and measuring an intercorporeal analyte includes: a detection layer containing at least one fluorescent indicator for generating fluorescence according to the concentration of the analyte; and an optical separation layer which is provided on the detection layer, is optically opaque, permits the analyte to penetrate therethrough, and prevents the penetration therethrough of at least one of living body substances possibly deteriorating the detection layer and/or obstructing the fluorescence.
