Abstract: A protein with an activity of inhibiting angiogenesis and inflammation, and a specific structure, use, and preparation method thereof are provided. The protein can inhibit both angiogenesis and inflammation, and can prevent and alleviate ophthalmic diseases such as age-related macular degeneration (AMD), diabetic retinopathy (DR), and pterygium to some extent based on a dual action mechanism.

Abstract: A recovery device for an unmanned underwater vehicle (UUV) includes a first recovery component arranged on an unmanned ship and a second recovery component arranged on the UUV. Two magnets are provided on an end of the first recovery component and an end of the second recovery component which are opposite to each other, respectively. A first cable of the unmanned ship is provided on an end of the first recovery component away from the magnet, and a second cable is provided on an end of the second recovery component away from the magnet. A thruster is provided on a side of the first recovery component. The UUV is recovered using the unmanned ship through the recovery components connected to the cables, which allows the locating and navigation errors to a large extent.

Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device. While running a social networking application, the first computing device listens to a near-field wireless communication signal broadcasted by a second computing device. After detecting the near-field wireless communication signal broadcasted by the second computing device, first computing device processes the near-field wireless communication signal to obtain identification information associated with the second computing device. The first computing device sends the identification information associated with the second computing device to a remote server supporting the social networking application and obtains a preset service page corresponding to the identification information associated with the second computing device from the server, and displays the preset service page within the social networking application on the first computing device.

Abstract: A method of recycling a polyester includes the steps of providing the polyester, preparing a solution containing water and an alcohol, submerging the polyester in the solution, and hydrolytically depolymerizing the polyester while the polyester is submerged in the solution.
