  • Publication number: 20240115753
    Abstract: An aroma diffuser comprises a compression plug connected to an air pump, an oil tube, an atomizing chamber, a spray outlet base, and a rotary spray outlet cover. The atomizing chamber comprises a chamber, a spray outlet sleeve, and a spray outlet, a distance between the air outlet and a chamber wall of the atomizing chamber is 11-13 times an aperture diameter of the air outlet, the spray outlet of the atomizing chamber extends downward to form a spray outlet channel, the spray outlet sleeve is sleeved outside of the spray outlet channel, atomized essential oil enters into the gaps between the spray outlet sleeve and the spray outlet channel from the groove notch and is then sprayed out, a bottom of the spray outlet sleeve is obliquely disposed and comprises a first reflux hole, and the rotary spray outlet cover is rotatably connected to the spray outlet base.

  • Patent number: 10400031
    Abstract: Described herein is a method of identifying a monoclonal antibody (or antigen-binding fragment thereof) that specifically binds a plurality of lyssaviruses for use in post-exposure rabies prophylaxis or in the treatment of clinical rabies. The method includes using a naïve antibody phage display library to screen for phage clones that bind whole recombinant rabies virus or cells expressing glycoprotein from multiple lyssaviruses (such as RABV, MOKV and WCBV) and/or specifically bind recombinant glycoprotein from different lyssaviruses.

  • Publication number: 20160114026
    Abstract: Described herein are recombinant rabies viruses encoding rabies virus glycoprotein and at least one heterologous glycoprotein from another lyssavirus, such as Mokola virus, Lagos bat virus and/or West Caucasian bat virus. In particular embodiments, the recombinant rabies virus includes two or three heterologous lyssavirus glycoproteins. The disclosed recombinant rabies viruses can be used as pan-lyssavirus vaccines to provide protection against lyssaviruses that cause rabies.

  • Patent number: 8524247
    Abstract: Described herein are recombinant rabies viruses comprising a heterologous nucleic acid sequence encoding an immunocontraceptive protein, such as gonadotropin-releasing hormone (GnRH) or zona pellucida 3 (ZP3). The recombinant rabies viruses disclosed herein are recovered by reverse genetics, replicate efficiently, elicit rabies virus neutralizing antibodies and immunocontraceptive peptide-specific antibodies in vaccinated animals, and protect vaccinated animals against wild-type rabies virus challenge. Further provided is a method of immunizing a non-human animal against rabies virus infection and simultaneously inhibiting fertility of the animal, comprising administering an immunogenic composition comprising one or more of the recombinant rabies viruses described herein.
