Abstract: Among others, the present invention provides beta-hydroxybutyrate (BHB) salt granules, comprising BHB salts and fillers. The present invention also provides methods for producing BHB salt granules, wherein the BHB salt granules are prepared by granulation process. The production methods may include (a) wet granulation; (b) extrusion; (c) spheronization; and (d) drying.

Abstract: The present invention provides methods, compositions (e.g., eyedrop or spongarion composition), and uses for alleviating and preventing age-associated vitreous degeneration in a mammal, comprising administrating to the mammal in need thereof a therapeutically effective amount of L-ergothioneine, an analog or derivative thereof, or a pharmaceutically acceptable salt, acid, ester, polymer, analog or derivative thereof, as an active ingredient. In particular, L-ergothioneine is capable of scavenging chronic reactive oxygen species directly and radically to mitigate and prevent HA depolymerization and HA decreasing-viscosity in the mammal's vitreous body; and/or improving vitreous liquefaction in the mammal.

Abstract: A side-by-side all-terrain vehicle, comprising: a vehicle body comprising a cockpit and a power compartment, the power compartment being located behind the cockpit; a powertrain comprising a power motor, the power motor being provided in the power compartment; and a power battery being provided in the cockpit, and the power battery being configured to supply power to the power motor. Thus, by using the power motor as a power source, exhaust gas emissions can be reduced, and the economic efficiency of an all-terrain vehicle can be improved. By providing the power battery in the cockpit, the interior space of the cockpit can be rationally used, so that insufficient rear space of the vehicle body is avoided, and the power battery suffers less external interference and has better usage safety.

Abstract: A pre-press head may be operated by an operating method. The pre-press head includes an adsorption unit and a control unit. The adsorption unit includes at least two vacuum adsorption structures each including a gas path and at least one gas hole communicated with the gas path. The control unit is configured to control, according to a size of a to-be-adsorbed object, formation of vacuum environment of each vacuum adsorption structure. The adsorption unit is configured to adsorb the to-be-adsorbed object under the control of the control unit. The solution provided by the application adjusts adsorption functions of the vacuum adsorption structures according to a size of a to-be-adsorbed circuit board, so that the pre-press head can be applicable to circuit boards having different sizes.

Abstract: A film feeding apparatus and a control method thereof are provided. The film feeding apparatus comprises a delivery head. A surface of the delivery head has an air suction region and an air blowing region, and the air suction region and the air blowing region respectively include an air hole; and by cooperation of air suctioning through the air hole of the air suction region and air blowing through the air hole of the air blowing region, a film is kept nearby the delivery head in a non-contact manner in the case that the delivery head adsorbs the film.
