  • Patent number: 10213491
    Abstract: Neonatal seizure is different from adult seizure, and many antiepileptic drugs that are effective in adults often fail to treat neonatal seizure. Gluconic acid, a natural organic acid enriched in fruits and honey, and the glucose oxidase enzyme, is shown herein to potently inhibit neonatal epilepsy both in vitro and in vivo. Sodium gluconate is shown to inhibit epileptiform burst activity in cell cultures and protect neurons from kainic acid-induced cell death. Sodium gluconate also inhibited epileptiform burst activity in brain slices in a manner that was much more potent in neonatal animals than in older animals. Consistently, in vivo EEG recordings also revealed that sodium gluconate inhibited the epileptic seizure activity in a manner that was much more potent in neonates than in adult animals. Mechanistically, sodium gluconate inhibits voltage-dependent CLC-3 Cl? channels both in neuronal cultures and in hippocampal slices.

  • Patent number: 10211367
    Abstract: An LED fabrication method includes forming release holes by focusing a laser at the substrate back surface, and forming stealth laser-blast areas by focusing a laser inside the substrate on positions corresponding to the release holes; communicating the release holes with the stealth laser-blast areas to release impurities generated during forming of the stealth laser-blast areas from the substrate through the release holes, thereby avoiding low external quantum efficiency resulting from adherence of the released material to the side wall of the stealth laser-blast areas. By focusing on a position with 10 ?m˜40 ?m inward from the substrate back side, adjusting laser energy and frequency to burn holes inside the substrate to penetrate and expose the substrate back surface, thereby effectively removing by-products, and reducing light absorption by such by-products, light extraction from a side wall of the LED can also be improved and light extraction efficiency is enhanced.

  • Publication number: 20180300750
    Abstract: Aspects of the disclosure provide a method for delivering a media file. A target delivery volume and an actual delivery volume of the media file corresponding to a same period of time are obtained. The target delivery volume is compared with the actual delivery volume to obtain a comparison result. A correlation parameter of the media file can be adjusted according to the comparison result. The correlation parameter can indicate a correlation between the media file and a delivery object of the media file. The media file can be delivered to the delivery object according to the adjusted correlation parameter.
