  • DEVICE AND METHOD FOR PROTECTING DIRECT CURRENT SOURCE
    Publication number: 20170365999
    Abstract: A device for protecting a direct current source and method are provided. Electric energy outputted from the direct current source is stored and an enable signal is received by the hiccup drive circuit. In a case that the enable signal is an OFF-ENABLE signal, the driving signal is generated based on the electric energy stored internally. By periodically switching on the switching device based on the driving signal, the output voltage of the direct current source is periodically short-circuited. Therefore, the issue of a large conduction loss in the conventional art is avoided, which is caused by the fact that a minimum required voltage for driving the electronic switch is required to be continuously provided by the output voltage of the direct current source.

  • INHIBITORY OLIGONUCLEOTIDE AND USE THEREOF
    Publication number: 20170335325
    Abstract: The inhibitory oligonucleotides (ODNs) strongly block NF-?B activation induced by TLR9 agonists and TLR7 agonists. The production of proinflammatory cytokines, such as interleukin-6 and tumor necrosis factor alpha, is inhibited by the inhibitory-ODNs. Interferon production from human PBMC induced by TLR9 agonist is prevented by the inhibitory-ODNs. These ODNs can be used as a remedy for the treatment of immune-mediated disorders such as rheumatoid arthritis, systemic lupus erythematosus (SLE), sepsis, multiple organ dysfunction syndromes.
