Disclosed is a system for detecting a protease inside a cell. In one embodiment, the system includes a chimeric protein that comprises as covalently linked components: 1) at least one optionally masked signal protein; 2) at least one protease-specific cleavage site; and 3) at least one detectable amino acid sequence. The invention has a wide spectrum of applications including use in the detection of novel protease inhibitors inside cells and tissue.

A reactor core coolant temperature measuring apparatus for measuring the temperature of the coolant flowing in the reactor core of a nuclear reactor comprises a γ-ray thermometer having a temperature measuring section arranged below the bottom of the reactor core and a γ-ray heat generation detecting section arranged between the bottom and the top of the reactor core, a cable for transmitting the signal output from the temperature measuring section and an output signal processing means for receiving the signal and computationally determining the local temperature of the coolant at the position of placement of the temperature measuring section.

Device for removing a complete vascular occlusion using a CTO catheter, at the distal end of which are disposed stretching tongs and IVUS monitoring, whereby the CTO catheter is combined with an IVUS catheter to form an integrated unit.

A machining tool comprises a frame mounting an extendable yoke slidable with respect to the frame in a first direction through one or more mounting pillars. A tool motor is mounted on the yoke. A drive mechanism for the yoke is also mounted in the frame, with a drive motor to drive the yoke drive mechanism. A belt is between pulleys on the drive motor and mechanism to transmit drive between them. A rotatable sleeve is around the tool motor and on which sleeve the belt engages on opposite sides of the tool motor, whereby the tool motor can extend between the drive motor and mechanism, thereby resulting in a compact arrangement of the tool.

The invention relates to the technical field of establishment of an animal model used for screening drug and researching disease mechanism, in particular to a screening method of a febrile convulsion model rat, which can be used for obtaining the model rat by screening in a way of combining a typical water bath heating induction model with artificial directional selection and mating breeding. Themethod is unique and can be used for successfully obtaining the good febrile convulsion sensitive model rat and a tolerance model rat.

The present invention relates to a cell culture medium additive comprising a xanthan polysaccharide and a mannan polysaccharide, such as a glucomannan or a galactomannan, that supports the growth of cells in suspension, and to a cell culture medium containing the additive. More particularly, but not exclusively, the present invention relates to a cell culture medium additive that supports the formation of multicellular bodies such as spheroids, and prevents sedimentation of cells without adversely affecting the physical properties of the cell culture medium.

A method and device for indicating a scanning condition and a scanning apparatus and scanning system related thereto are provided. The method includes: converting a scanning condition of a scanning apparatus into a control instruction for controlling a light strip to provide an indication; and executing the control instruction to control the light strip to provide the indication in the case of the scanning condition, wherein the light strip is mounted on an exterior of the scanning apparatus. Thus, the scanning condition of a scanning apparatus is converted into a control instruction for controlling the light strip to provide the indication, and the control instruction can be executed to control the light strip on the exterior of the scanning apparatus to indicate the scanning process when the scanning condition of the medical-scanning apparatus occurs.

The inventions aims to provide a tungsten filament rope coiling machine charge coupled device (CCD) image capture display method and a detecting device thereof so as to solve the problem of monitoring in a tungsten filament rope coiling process. The tungsten filament rope coiling machine CCD image capture display method is characterized in that image formation of a tungsten filament rope is carried out in a twisting process, images of the tungsten filament rope are magnified by a precision microscope, projected on a CCD chip and processed into electric information which is transmitted to a display processing system through a CCD, and the images of the tungsten filament rope are enlarged and displayed in a display surface. The detecting device which achieves the tungsten filament rope coiling machine CCD image capture display method is characterized in that a CCD image capture display detection device body is fixedly connected with a special base arranged on a tungsten filament rope coiling machine through a microscope base, the upper portion of the microscope base is provided with a light source which directly shines on the tungsten filament rope, the CCD is arranged on the upper portion of the microscope, the CCD chip is connected with a display. The tungsten filament rope coiling machine CCD image capture display method and the detecting device thereof have the advantages that silk, strands and ropes are quite thin and are enlarged, so that observation and monitoring are convenient, direct and clear; the display method and the detecting device are beneficial for finding out defects of tungsten filament, tungsten filament strands and tungsten filament ropes in a production process, and enhance guaranteeing of quality of tungsten filament rope products and improvement of monitoring level.
