Abstract: Disclosed are a method for preparing a porcine-derived interferon-delta 5 (pIFN-?5) and an application of the pIFN-?5, where the method for preparing pIFN-?5 includes the following steps: step S1, obtaining a DNA fragment containing pIFN-?5 gene through reverse transcription-polymerase chain reaction (RT-PCR) amplification by using the total RNA of pretreated porcine small intestinal epithelial cells IPEC-J2; step S2, inserting the DNA fragment containing pIFN-?5 gene into an exogenous expression vector to construct a recombinant expression vector for expressing the pIFN-?5 gene; and step S3, introducing the recombinant expression vector into a suitable host cell, and driving the host cell to express the pIFN-?5 gene to obtain the pIFN-?5. The recombinant pIFN-?5 protein is used to prepare drugs or preparations for inhibiting infection of porcine epidemic diarrhea virus (PEDV), porcine transmissible gastroenteritis virus (TGEV), porcine delta coronavirus (PDCoV) and porcine rotavirus (PRoV).

Abstract: The present invention is directed to a method for fabricating a gold nanoparticle, the method comprising the steps of contacting a gold ion with a protein, wherein the protein has an inner cavity that can accommodate the gold ion, separating the protein with the encapsulated gold ion(s) from non-encapsulated gold ions, contacting the protein-encapsulated gold ion with a first reductant to reduce the gold ion and form a gold nanocluster seed in the inner cavity of the protein, wherein the first reductant is a strong reductant, and contacting the gold nanocluster seed in the inner cavity of the protein with a second reductant to mineralize and grow the gold nanoparticle.

Abstract: There is provided a stabilizer for an optical device that forms part of an electronic device and an electronic device including the stabilizer. The stabilizer includes two first actuators, each of which includes a first coil assembly and a first block of ferromagnetic material, each of the two first coil assemblies being configured to generate, in response to a first electrical signal applied thereto, a first attraction force toward a respective first block of ferromagnetic material, the first blocks of ferromagnetic material being attached to a socket for the optical device; and a rotating device configured to rotate the socket around an optical axis of the optical device in response to the first attraction force. The image stabilization solution according to the present invention is both applicable to AF camera modules and to fix focus camera modules.
