  • Publication number: 20240132979
    Abstract: A set of primers and probes for simultaneous detection of Cymbidium mosaic virus (CymMV), Odontoglossum ringspot virus (ORSV), and Cymbidium ringspot virus (CymRSV) and a method for detecting CymMV, ORSV, and CymRSV, along with a method for their detection, are disclosed. The method involves designing multiplex real-time quantitative PCR detection primers and probes for CymMV, ORSV, and CymRSV and applying these primers and probes to the real-time quantitative PCR simultaneous detection of CymMV, ORSV, and CymRSV. It allows for faster detection of CymMV, ORSV, and CymRSV, taking only one-third of the time compared to uniplex real-time quantitative PCR technology, thereby reducing testing costs by approximately ? to ½ for each sample. The primers and probes are highly specific and sensitive, with a sensitivity as low as 1 to 10 copies. It provides an efficient and feasible detection method for early detection and prevention of CymMV, ORSV, and CymRSV.

  • Publication number: 20190239282
    Abstract: Disclosed are an S1AP signaling transmission method and apparatus. The method comprises: an intelligent mobile edge device receives an SCTP message carrying uplink S1AP signaling of a terminal sent by a Small Cell, determines an operator network corresponding to the terminal according to an S1AP ID carried in the uplink S1AP signaling, and sends the SCTP message carrying the uplink S1AP signaling to the He-GW of the operator network; the intelligent mobile edge device receives an SCTP message carrying downlink S1AP signaling of the terminal sent by the He-GW of the operator network, determines the Small Cell corresponding to the terminal according to an S1AP ID carried in the downlink S1AP signaling, and sends the SCTP message carrying the downlink S1AP signaling to the Small Cell. In this way, a Small Cell may access networks of multiple operators to provide network services for terminals of different operators.

  • Publication number: 20180117123
    Abstract: An exenatide-containing composition is in the form of microspheres, which are prepared by using exenatide acetate and polylactic-co-glycolic acid (PLGA) as raw materials, and the content of acetic acid in the prepared composition is lower than 0.01%. A method for preparing the exenatide-containing microspheres includes selecting a cleaning fluid of a proper external water phase and a proper amount to clean microspheres, and selecting a proper re-drying temperature to cure the microspheres after the microspheres are freeze-dried.

  • Patent number: 6734318
    Abstract: A method of reacting a first compound to produce a second compound includes the step of contacting a first non-fluorous phase including the first compound with a first fluorous phase at a first phase interface. The first compound distributes between the first fluorous phase and the first non-fluorous phase. The method further includes the steps of contacting the first fluorous phase with a second non-fluorous phase at a second phase interface and including at least a third compound in the second non-fluorous phase that reacts with the first compound to produce the second compound. The second compound has a distribution coefficient less than the first compound. This method can, for example be used to separate the second compound from unreacted first compound wherein, for example, the first compound is of a fluorous nature and distributes more readily into (or transports more quickly through) the fluorous phase than does the second compound.
