Abstract: The present disclosure relates to a method to improve the encapsulation efficiency and physicochemical stability of ginsenosides Rg3 and CK nano-emulsion, belonging to the field of functional emulsions. The method to improve the encapsulation efficiency and physicochemical stability of ginsenosides Rg3 and CK nano-emulsion, includes the following steps: (1) WPI, Tween 80 and water were mixed evenly according to the amount ratio of 0.5 g:0.5-0.7 g:50 mL to obtain the aqueous phase; (2) Mixing a saponin extract containing the minor ginsenosides Rg3 and CK with edible oil evenly to obtain the oil phase; (3) Mixing the aqueous phase with the oil phase, carrying out shearing dispersion to obtain coarse emulsion, and then allowing the coarse emulsion to be subjected to microfluidization homogenization to obtain an oil-in-water nano-emulsion containing the minor ginsenosides Rg3 and CK.

Abstract: A miniature combined multi-axis force sensor structure includes a sensor body, a first shell and a second shell, two horizontal main beams and two vertical main beams are arranged on the periphery of an inner round platform in a cross shape, tail ends of the horizontal main beams and the vertical main beams are each connected to a vertical floating beam, and the horizontal floating beams consist of two thin-walled cambered beams; two ends of the horizontal floating beam are each connected to an outer round platform by means of an annular platform; the sensor body is arranged between the first shell and the second shell; strain gauges are stuck on the horizontal main beams and the vertical main beams to form two Wheatstone bridges; and when force/torque acts on the cross beam, the sensor deforms, and the resistance value of strain gauge at corresponding position changes.

Abstract: A laminated electronic device includes a laminate wherein the laminate includes a plurality of laminated insulator layers, the laminate has a multi-layer coil pattern provided between the plurality of insulator layers in a laminated manner, adjacent layers of the coil pattern are electrically connected through conductive via holes to form an internal coil, a first external electrode and a second external electrode are disposed on a bottom surface of the laminate which is parallel to a direction of lamination. In surface-mounting of the laminated electronic device, it only needs to connect the external electrodes on the bottom surface of the laminate to a soldering board, and needs not to preserve a space for solder wicking in the surrounding, thereby significantly saving the occupied space of surface mount components to achieve high-density mounting; in addition, the Q value of the product is improved.

Abstract: The present invention relates to hepatitis A vaccine, especially to a lyophilized attenuated hepatitis A vaccine which can be stored at ambient temperature for extended periods of time, and to a method for producing the same. The present invention further relates to a stabilizer for lyophilized live vaccine and its use in improving thermostability of lyophilized live vaccine during lyophilization processing and storage period after lyophilization.

Abstract: A combined hepatitis A-measles live vaccine, its lyophilized formulations with enhanced storage stability and methods of preparing the same by mixing the viral stocks of hepatitis A virus and measles virus or by propagating the two viruses on same diploid cell substrate are disclosed. The combined live vaccine thus prepared is a useful vaccine for preventing the infections with hepatitis A and measles without causing any interference between antigenicity of the two viruses and any serious adverse events due to their mixing or co-culturing.
