Abstract: The present disclosure relates to a searchable encrypted data sharing method and system based on blockchain and homomorphic encryption, which protects security of sensitive data on the blockchain and realizes searchable and homomorphic calculation of data ciphertext. According to the present disclosure, a data owner encrypts the generated sensitive data and the keywords extracted according to the data with his own key, and then sends the encrypted transaction information to the cloud server. The cloud server verifies the identity of the data owner. If the verification succeeds, the uploaded ciphertext data is stored on a local server, and a ciphertext index, keyword ciphertext and related evidences of the data storage are uploaded to an alliance chain. The alliance chain node verifies the consistency of the uploaded transaction information, and if the verification succeeds, the transaction information is recorded.

Abstract: The present disclosure provides compositions and methods for inhibiting viral pathogenesis by targeting long noncoding ribonucleic acids.

Abstract: The present disclosure provides compositions and methods for inhibiting respiratory viral infections, inflammatory diseases, and/or respiratory inflammation.

Abstract: A photosensitive polyimide resin for ultraviolet curing-based three-dimensional printing, which is prepared from 40-60 parts by weight of an active group-containing polyimide resin; 20-50 parts by weight of an organic activator; and 2-5 parts by weight of a photoinitiator. This application further provides a method for preparing the photosensitive polyimide resin.

Abstract: Described herein are compositions and methods for inducing Type I interferon production. The compositions described comprise immunostimulatory oligonucleotide duplexes including a 5? terminal monophosphate-CUGA-3? (SEQ ID NO. 1) sequence. Compositions comprising the immunostimulatory oligonucleotide duplexes described can be used for the treatment of diseases or disorders that respond to interferons.

Abstract: A single screw extrusion sprayer of a 3D printer includes a drive mechanism, a stir mechanism, and an extrusion mechanism. A side of the drive mechanism is connected to the stir mechanism to drive the stir mechanism to rotate, and another side of the drive mechanism is connected to the extrusion mechanism to drive the extrusion mechanism to rotate. The extrusion mechanism is connected to the stir mechanism to deliver stirred particles to the stir mechanism. The single screw extrusion sprayer has a compact structure and a light weight, and can be used in desktop 3D printers. The particle material can be melted for 3D printing.
