  • Publication number: 20240091172
    Abstract: A drug for antagonizing the replication of porcine reproductive and respiratory syndrome virus (PRRSV) and an application thereof. By using a viral infection test, a drug which antagonizes PRRSV—xanthohumol—is discovered for the first time from among a natural drug library of 386 plant sources. Xanthohumol can effectively inhibit PRRSV replication on both Marc-145 and PAM cells. Five xanthohumol derivatives having different molecular structures are artificially synthesized, and it is discovered that a derivative Xn-4 has the strongest inhibitory effect on virus replication in vitro. Test results of artificial infection and drug therapy in piglets show that the Xn-4 can effectively inhibit PRRSV viremia, relieve clinical symptoms of infected pigs, and significantly reduce lung inflammation and pathological damage.

  • Patent number: 10977133
    Abstract: Improved methods, systems and apparatus for storing and repairing multimedia files are provided that overcome the limitations of existing multimedia file repair technologies. Backup copies of the multimedia container information associated with given multimedia content data are stored, along with the multimedia content data, on an external storage detachably coupled to a recording device. A primary copy of the multimedia container information is stored on an internal storage associated with the recording device. The recording of the primary container information and the content data is performed in real-time or nearly real-time as the content data is captured by the recording device. In the case of an abnormal event (e.g., battery failure, disconnect of storage media), container information may be selected from the primary copy or the backup copies of the container information, thereby increasing the likelihood that the container file can be successfully repaired or regenerated.
