  • Biological active peptide for improving enzyme activity of ACE2 and application thereof
    Patent number: 12247087
    Abstract: The present application provides a biological active peptide from seawater pearl, the sequence of which is Ile-Pro-Ser-Thr-Thr-Pro-Phe-Pro-Ser-Thr-Thr-Val-Ala-Thr-Thr-Thr-Met, and the name of which is SCOL polypeptide. The biological active peptide can improve an ACE2 enzyme activity to 3.76 times, and can be applied in preparation of a drug improving an ACE2 activity, treating hypertension, anti-heart failure, anti-tissue fibrosis, anti-inflammation, and type 2 diabetes mellitus and the complication thereof, and relieving neuropathic pain. The biological active peptide can be specifically bound to the ACE2, effectively inhibits the 65% binding between novel coronavirus S protein and the ACE2, can be applied in preparation of an anti-coronavirus infection drug as an inhibitor, and specifically applied in preparation of anti-novel coronavirus drug.

  • Timing synchronization in an orthogonal frequency-division multiplexing (OFDM) system
    Patent number: 9491025
    Abstract: A transmitting end of an Orthogonal Frequency-Division Multiplexing (OFDM) wireless communication system may generate a training sequence and attach the training sequence to a data sequence that contains information data. A receiving end of the OFDM wireless communication system may identify a starting position of the data sequence and further extract the data sequence.
