Abstract: A method for selectively and easily quantifying the L-form and/or D-form amino acids to be measured using an aminoacyl tRNA synthetase (AARS) with high sensitivity, and an amino acid quantification kit. A method for quantifying amino acids (L-AA and/or D-AA) in a sample using an AARS, wherein the amino acids and the AARS are released from an aminoacyl AMP-AARS complex once formed, and they are used again for forming the aminoacyl AMP-AARS complex, so that reaction products such as pyrophosphoric acid to be measured can be ultimately produced up to a molar number larger than that of the amino acids contained in the sample, and an amino acid quantification kit for performing the method.

Abstract: The present invention provides a bending device which is capable of easily controlling a bending motion with superior controllability. A portion of an elastic tube body (11) opposite a portion in which a non-stretching body (4) is fixed inflates in a circumferential direction of the elastic tube body (11) in response to increase in an internal pressure of the elastic tube body (11), and an elastic tube (1P) bends in a step-wise angle corresponding to the number of layers of a multi-layer structure. The portion of the elastic tube body (11) in which the non-stretching body (4) is fixed is thicker than the remaining portion of the elastic tube body (11).

Abstract: There is provided a medical device whose occupied space is reduced. According to an aspect of the present invention, a medical device (1) adjusts a position of a medical instrument including a rod-like insertion unit (201) for being inserted into a body. The medical device includes an ultrasonic actuator that holds the insertion unit of the medical instrument, and that displaces or rotates the insertion unit with respect to the ultrasonic actuator, and an actuator fixing unit (101 and 102) that fixes a position of the ultrasonic actuator to a surgical site.

Abstract: [Problem to be solved] It is to provide a method for selectively and easily quantifying the L-form and/or D-form amino acids to be measured using an AARS with high sensitivity, and an amino acid quantification kit. [Solution to Problem] A method for quantifying amino acids (L-AA and/or D-AA) in a sample using an AARS, wherein the amino acids and the AARS are released from an aminoacyl AMP-AARS complex once formed, and they are used again for forming the aminoacyl AMP-AARS complex, so that reaction products such as pyrophosphoric acid to be measured can be ultimately produced up to a molar number larger than that of the amino acids contained in the sample, and an amino acid quantification kit for performing the method.

Abstract: A high-density shape reconstruction is conducted in measuring animal bodies as well. An image processing system has a projection device, an imaging device, and an image processing apparatus connected to the projection device and the imaging device, wherein the projection device projects a projected pattern to an observation target, the imaging device captures the projected pattern, and the image processing apparatus performs shape reconstruction based on an input image including the projected pattern. The image processing apparatus includes a unit for fetching the input image captured by the imaging device and performing line detection for the projected pattern projected by the projection device, wherein the projected pattern is a grid pattern formed of wave lines; and a unit for performing shape reconstruction by associating intersection points of vertical and horizontal lines extracted by the line detection with the projected pattern.
