摘要:
A synthesis method for pyrrole-imidazole polyamide is automated at a higher level and can produce a product with a high yield in a more stable manner. In a solid phase synthesis method, the automated synthesis of a polyimide can be promoted by using HCTU as a condensation-activator, the yield of a product can be increased by charging a monomer in a solid form, and a pyrrole-imidazole polyamide having any sequence can be synthesis by combining the synthesis method with a manual synthesis with an acid chloride.

It is intended to provide a novel monomer unit by which Z type DNA can be more effectively stabilized, a reagent for integrating this monomer unit into an oligonucleotide, and a method of stabilizing Z type DNA by using the reagent. Namely, a guanosine derivative represented by the following general formula [1]: wherein R1 represents acyl; R2 represents lower alkyl; R3 represents tri-substituted silyloxy or tetrahedropyranyloxy; and R4 represents cyanoethyl or allyl; a reagent for stabilizing Z type DNA which contains the guanosine derivative; and a method of stabilizing Z type DNA by using the guanosine derivative. It is also intended to provide a method of transferring guanosine having lower alkyl at the 8-position into an oligonucleotide by using the guanosine derivative; and an oligonucleotide carrying guanosine having lower alkyl at the 8-position transferred thereinto.

A method for screening the effect of a segment A (chemical species A) on a substance (for example, a cell) containing DNA or RNA by using artificial chemical species. Namely, a method of detecting or identifying the function of a chemical species A on a substance containing DNA or RNA by using one or more chemical species represented by the following general formula (I) which are capable of recognizing a DNA base sequence; a kit therefor; and a plate to be used therein: B-L-A (I) wherein B represents a chemical structure containing an non-natural base capable of recognizing a DNA base sequence; A represents a chemical structure having an interaction with DNA; and L represents a linker whereby the chemical structures A and B can be linked together.
摘要:
A bias current to be supplied to an amplification circuit 60 is drawn out of a collector of a transistor Q11 of a bias circuit 10. The drawn-out bias current is input to a base of a transistor Q13 via an attenuation filter F2 and is output from an emitter of the transistor Q13 in the state where the voltage thereof is reduced by a level corresponding to Vbe. The attenuation filter F2 is conducted in a DC manner, and attenuates a component of a frequency fH(=2ft−fr) defined by a transmission frequency ft and a receiving frequency fr of a radio frequency signal. The bias current output from the emitter of the transistor Q13 is supplied to the amplification circuit 60 via an attenuation filter F1. The attenuation filter F1 is conducted in a DC manner, and attenuates a component of a frequency fL(=|fr−ft|).
摘要:
This service system includes a portable terminal for acquiring a game character to be distributed, and then, executing a game in collaboration with a processor main body, an external station for making communication with the portable terminal via a short distance wireless equipment, and a service server for distributing the game character to the external station. The portable terminal transmits to the external station the contents of a history information storage section for storing history information concerning a game and a game character depending on a user that possesses the portable terminal. The external station receives the history information transmitted from the portable terminal, and then transmits to the portable terminal the game character information transmitted by referring to the history.
摘要:
An output apparatus which produces the print output by saving in a first memory print data input via a two-way interface, and converting the print data into the print out information, comprising a second memory different from the first memory for saving the print data with a print ID number added which is input via the interface, a retrieving unit for retrieving corresponding print data of the second memory based on a print ID number input from the outside, and an output unit for outputting the retrieved print data converted into the print out information.
摘要:
A route guidance system for a pedestrian. An input unit inputs a departure point and a destination point of the pedestrian. A route data memory stores route data representing position and connection of each route comprising a road network. A route calculation unit calculates a route from the departure point to the destination point by referring to the route data in said route data memory. A landmark memory stores landmark data for the pedestrian's confirmation; a landmark represents a signpost of the departure point, the destination point, and the route. A landmark selection unit selects the landmark data corresponding to the route calculated by said route calculation unit from said landmark memory. A presentation unit presents a route guidance to the pedestrian using the calculated route and the selected landmark data.
