The unnatural amino acid is applicable to numerous fields, especially in preparation of a recombinant protein or a recombinant protein conjugate.

Abstract: A system that allows for channel and platform agnostic automated scheduling. A user that is registered with the system may add an automated assistant into a pre-existing communication thread or channel, such as a short messaging service (“SMS”) conversation between multiple friends. Any user in the thread may interact with the assistant even if not registered with the system. Once present, the assistant analyzes messages sent to the thread for wake words that trigger actions or responses by the system, including automated scheduling actions. When scheduling is invoked, the system will find acceptable times based on top-down and bottom-up availability provided by registered users, and will propose meeting times until one is accepted by some or all of the participants. Once accepted, the system will confirm the meeting, update linked calendars, and provide reminders to attendees.

Abstract: The present disclosure provides use of chemokine receptor CXCR5, wherein CAR-T cells with enhanced chemotaxis are obtained by modifying chimeric antigen receptor T cells (CAR-T cells) utilizing the chemotactic signal between CXCR5 and its ligand CXCL13. The chemokine receptor CXCR5 can guide CAR-T cells to migrate to tumors. It has an excellent ability to enhance the chemotaxis of CAR-T cells, can specifically clear tumor cells, and effectively solve the problem of poor efficacy of the existing CAR-T therapy for solid tumors, thereby exhibiting broad application prospects and great market value.

Abstract: A communication antenna and radiation unit thereof with tapered clearance slots for transceiving radiation signals disposed at four corners of the radiation unit. The slots form groups and are arranged and fed by two feeding units. A middle portion of the radiation unit is a flat central platform. Peripheries of the radiation unit are turned up to form folded edges. The communication antenna includes a reflecting plate and a radiation unit operating at a low frequency. The central platform has a high-frequency radiation element. The radiation unit has a small aperture and is lightweight, so the antenna size is reduced, and a radiation performance indicator can be ensured. The radiation unit is applied to a multi-frequency antenna, has little effect on a high-frequency oscillator, and is especially suitable for a multi-frequency base station antenna with a low-frequency unit and a high-frequency unit forming an array in a nested manner.
