  • Publication number: 20190177354
    Abstract: Provided are a series of crocins compounds and related pharmacological applications thereof in prevention and treatment of Alzheimer's disease. The series of crocins compounds are obtained by taking the Chinese herb, namely Gardenia jasminoides Ellis, as a raw material and separating same by means of various methods. The compounds playing a role in preventing oxidative injury caused by hydrogen peroxide (H2O2) and excitatory amino acid injury caused by L-glutamic acid are screened out by in-vitro cell experiments. The results show that the crocins compounds have good effect in preventing cell injury caused by H2O2 and L-glutamic acid. The compounds have good effect in preventing and treating Alzheimer's disease due to the fact that significant rise of oxidative stress and excitatory amino acid is a key factor for nerve injury in Alzheimer's disease, and have broad development and application prospect.

  • Patent number: 10303743
    Abstract: An online system stores online documents, where each online document has a layout. The system creates augmented online documents by combining the online documents with one or more content items. The system stores client interactions with the content items, responsive to presenting the augmented online documents via a client device. The system receives a new online document. The system creates new augmented online documents by combining the new online document with one or more new content items. For each new augmented online document, the system generates a score based on one or more features describing the layout of the new augmented online document. The system selects a new augmented online document based on the generated scores and sends the selected new augmented online document for presentation via a client device.

  • Patent number: 10306720
    Abstract: A circuit for driving an LED lighting device from an AC power source includes a rectifier and one or more strings of LEDs. Each string of LEDs includes multiple LEDs. A controller produces control signals that open and close a set of switches that corresponding with the LED groups. The controller uses a current mirror with a pair of reference branches situated between a reference voltage and ground and between the switches and ground. Each reference branch has a first-in-line resistor between the reference voltage and the current mirror which primarily set the reference current through the controller by having the highest impedances, and the control signals are produced by a set of resistors on one of the branches. Each branch also has a last-in-line resistor between the current mirror and ground with the lowest impedances. The selection of the highest impedances and lowest impedances reduces sensitivity to temperature variations.
