Abstract: The present disclosure belongs to the technical field of health food, and in particular, relates to the use of PAYCS in the regulation of intestinal flora, metabolites, and brain neurotransmitters. PAYCS remedies scopolamine-induced memory impairment in mice through target oxidation, inflammatory stress and regulation of the intestinal microorganism-metabolite-brain neurotransmitter axis through PAYCS. PAYCS improves the memory pathway through the intestinal microorganism-metabolite-neurotransmitter axis. PAYCS can significantly reduce serum MDA and LDH levels and significantly increase liver SOD content. PAYCS-H inhibits the increase of liver TNF-? and IL-1?, while PAYCS-L can only reduce the content of TNF-? in the liver. Thus, PAYCS-L changes the ratio of Bacteroides/Firmicutes and increases the relative abundance of plants such as Cactaceae and Prevotellaceae, improving the neurotransmitters associated with the metabolism of tryptophan in the brain.

Abstract: The present application provides a three-axis linkage embroidery machine frame and an embroidery machine. The three-axis linkage embroidery machine frame includes a supporting frame, an X-axis driving mechanism, a Y-axis driving mechanism and a Z-axis driving mechanism. The X-axis driving mechanism is arranged on the supporting frame, the Y-axis driving mechanism is respectively coupled with the X-axis driving mechanism and the Z-axis driving mechanism. The advantageous effect of the present application is that, through the linkage of the X-axis driving mechanism, the Y-axis driving mechanism and the Z-axis driving mechanism, not only can the embroidery product be driven to move in the directions of the X-axis and the Y-axis, but also the embroidery product can be driven to rotate 360°, so that it is possible to avoid that the embroidery direction is the same as the thread taking direction of the rotating shuttle when embroidering.

Abstract: The present invention provides a method and a terminal for receiving FM radio signals, the method includes: Acquiring a position information of a terminal for receiving the FM radio signals; obtaining a region information of the terminal according to the position information; obtaining a radio station list corresponding to the region information; displaying the radio station list; and broadcasting a radio station which is selected from the radio station list. By the method, the terminal can update the radio station list in time, so that flexibility for receiving radio signals is improved. In addition, if being transferred from one region to another region, the terminal will switch to frequencies of the new region and receive radio signals in the new region with less time.

Abstract: The present invention provides a method for managing conflicts between audio applications and a conflict managing device for the audio applications, the method includes: Acquiring state information of audio applications; determining a processing strategy for the audio applications based on an arbitration strategy when conflicts happen between the audio applications; and adjusting states of the audio applications according to the processing strategy. And the method can automatically adjust states of the audio applications based on the arbitration strategy when conflicts happen between the audio applications, so as to avoid poor audio and visual effects caused by the conflicts.

Abstract: The present invention provides a vehicle-mounted device, a method for activating the vehicle-mounted device, and a vehicle-mounted system.
