Abstract: The application provides drugs, expression vectors, and their applications in the treatment of NAFLD and related diseases, pertaining to the technical field of targeted drugs. The drugs include streptavidin or a recombinant expression vector for streptavidin. Streptavidin can bind to acetyl CoA carboxylase 1, alter its subcellular localization within mammalian cells, and ultimately inhibit de novo lipogenesis. Ectopic expression of streptavidin can inhibit lipid accumulation within mammalian cells. Compared with chemical small-molecule drugs, streptavidin, as a protein drug, exhibits relatively lower liver and kidney toxicity. Streptavidin might be a relatively mild inhibitor of acetyl CoA carboxylase, avoiding a severe side effect of hyperlipidemia. Furthermore, streptavidin is very stable, which might be conducive to drug delivery and adaptable to different administration methods.

Abstract: A task scheduling method and system, and a hardware task scheduler are disclosed, and pertain to the field of computer technologies. The hardware task scheduler provides task scheduling for a central processing unit CPU core to select a candidate task. After selecting the candidate task, the CPU core actively sends metadata of the candidate task to a first storage area, and actively sends a context of the candidate task to a cache, where the first storage area is located in storage space whose access speed is higher than that of a memory. When performing task switching, the CPU core reads the metadata of the candidate task from the first storage area, and reads the context of the candidate task from the cache. In this way, latency of obtaining the metadata and the context of the candidate task by the CPU core is reduced, and low-latency task switching is implemented.

The method includes: displaying a live broadcast picture, the live broadcast picture including a live broadcast interactive role, the live broadcast picture being a live broadcast picture acquired when an anchor account conducts a virtual activity on a first virtual role in a virtual world; and displaying the live broadcast interactive role performing a first interactive action in response to the virtual activity of the first virtual role in the virtual world meeting a trigger condition. In this application, by adding the live broadcast interactive role and connecting the live broadcast interactive role with the first virtual role in the virtual world, interactive modes between the anchor user and the audience user in the process of webcasting are enriched, thus improving interactive efficiency in the process of webcasting.

To form the aspherical hollow silica particles, deposition of a silica shell on a calcium carbonate template using a sol-gel chemistry is employed. Subsequent dissolution of the calcium carbonate template forms voids (e.g., a hollow interior) in the aspherical hollow silica particles.

Abstract: Disclosed are a method, an apparatus, and a system for implementing video stream switching. The method can determine switching reference information of a first reference frame trailer packet of a first video stream and switching reference information of a second reference frame trailer packet of a second video stream, when receiving a switching instruction; and switch from the first video stream sent through the target egress port to the second video stream based on the switching reference information of the first switching packet and the switching reference information of the second switching packet. Because locations of data packets sent before and after switching are considered during video stream switching, damage caused by a switching operation to a transmitted video image can be effectively reduced.
