Abstract: An application of a transgenic stem cell-derived exosome in preparing a medicament or whitening cosmetic is provided. In the present disclosure, miR-27b-3p is transfected into an epidermal stem cell, and a transgenic stem cell-derived exosome is harvested. It is experimentally verified that the exosome can inhibit the expression of PIK3R3 protein in melanocytes and the proliferation and migration of melanocytes; and safety experiments further demonstrate the safety of the exosome. Therefore, corresponding medicaments or cosmetics prepared from the exosome have excellent medicinal and cosmetic application prospects.

Abstract: The present invention provides a flexible reciprocating linear seedling separating device for a pot seedling transplanter, including a frame, a seedling cup opening and closing device, a linear transmission device, a seedling cup moving device, several seedling cups and a control system. A flexible linear transmission device is fixed on the frame, a seedling cup moving device is fixed on the flexible linear transmission device, and a seedling cup opening and closing device is fixed on the seedling cup moving device. Several seedling cups are fixed on the seedling cup moving device. The control system is respectively electrically connected with a motor of the linear transmission device and a cylinder of the seedling cup opening and closing device. The control system controls the motor to drive flexible linear transmission device to move seedling cup moving device, thereby driving the seedling cups to reach a designated position and receive the pot seedlings.

Abstract: The present disclosure discloses an apparatus, method, and electronic device. The apparatus includes a processor and a biometric sensor coupled to the processor. The biometric sensor is configured to detect a plurality of biometric features of a user. Each biometric feature may be associated with a value. The processor may determine a sequence of values from the biometric features. The processor may determine the sequence for comparison with a predetermined sequence of values to verify an identity of the user based, at least in part, on the comparison.

Abstract: Electronic device and control method of the electronic device are provided. The method includes detecting a current temperature of the electronic device. In response to the current temperature matching a first condition, the method controls an app at the electronic device to switch from a first running state to a second running state. In response to the current temperature matching a second condition, the method controls currently-operating components at the electronic device to switch from a first operating state to a second operating state. The disclosed control method and electronic device ensure the normal operation of the electronic device and the regular user experience in using the electronic device.
