摘要:
The present invention relates to a high throughput screening method of a binding inhibitor between caspase3 and xIAP and chromomycin screened using the same, and more specifically, the present invention provides a method for screening anticancer substance, the method comprising the steps of reacting caspase3 or xIAP and candidate inhibitors of the binding between caspase3 and xIAP on a biochip for detecting caspase3:xIAP interaction, and selecting a candidate substance inhibiting the binding of caspase3 to xIAP as an anticancer substance, and an anticancer agent inhibiting caspase3:xIAP binding, which is screened by the above method. According to present invention, it is possible to develop a target-oriented anticancer agent focused on xIAP and caspase3, apoptosis-related proteins and thus it can be applied to tailored medication and combination therapy. Moreover, glycoside antibiotic chromomycin, screened by the present invention has inhibitory activity of the binding between xIAP and caspase3 involved in apoptosis, so that it can be used as a therapeutic agent for myelogenous leukemia and solid tumors.

An antenna comprises a first conductive layer, a second conductive layer and an LC resonance circuit. The first conductive layer has plural elements and is disposed adjacently to each other. The second conductive layer is disposed at a predetermined distance from the first conductive layer via a dielectric substrate. The LC resonance circuit comprises connection for electrically connecting the elements and the second conductive layer. The LC resonance circuit takes a resonance state in which impedance becomes high in the operating frequency of the antenna. Of the plural elements, a power feeding section is provided in each of any two adjacent elements. Power is fed to the power feeding sections during transmission so that signals of the operating frequency are opposite in phase, and signals of the operating frequency inputted to the antenna are outputted in opposite phase from the power feeding sections during reception.

A first metal plate for transmission and a second metal plate for transmission are closely-attached to a first surface and a second surface of a dielectric body, respectively. An outer edge of the first metal plate substantially symmetrically faces an outer edge of the second metal plate via the dielectric body. A metal plate for matching is arranged inside a hole formed on the second metal plate, with a slit formed with an inner wall of the hole, and is fixed to the dielectric body. The metal plate for matching is electrically connected to the first metal plate via a through hole penetrating the dielectric body. An IC chip is surface-mounted to connect the second metal plate with the metal plate for matching.

Disclosed herein is a dielectric waveguide antenna including: a dielectric waveguide transmitting a signal applied from a power feeder; a dielectric waveguide radiator radiating the signal transmitted from the dielectric waveguide to the air through a first aperture; and a matching unit formed in a portion of the dielectric waveguide and controlling a serial reactance and a parallel reactance to thereby perform impedance matching between the dielectric waveguide radiator and the air, in order to reduce reflection generated in the first aperture during the radiation of the signal through the first aperture. Reflection in the aperture is reduced through the matching unit having various structures, thereby making it possible to improve characteristics of the dielectric waveguide antenna.

摘要:
A multi layered high impedance structure presents a high impedance to multiple frequency signals, with a different frequency for each layer. Each layer comprises a dielectric substrate, and an array of radiating elements such as parallel conductive strips or conductive patches on the substrate's top surface with a conductive layer on the bottom surface of the bottommost layer. The radiating elements of succeeding layers are vertically aligned with conductive vias extending through the substrates to connect the radiating elements to the ground plane. Each layer presents as a series of parallel resonant L-C circuits to an E field at a particular signal frequency, resulting in a high impedance surface at that frequency. The new structure can be used as the substrate for a microstrip patch antenna to provide an optimal electrical distance between the resonator and backplane at multiple frequencies. It can also be used in waveguides that transmit multiple signal frequencies signals in one polarization or that are cross-polarized. As a waveguide it maintains a near-uniform density E and H fields, resulting in near uniform signal power density across the waveguide's cross-section.
