  • Publication number: 20240083703
    Abstract: A sheet conveying device includes a conveyor, a sound collector, and circuitry. The conveyor conveys a sheet. The conveyor conveys a sheet in a sheet conveyance direction. The sound collector collects an operating sound generated by a conveyance of the sheet. The circuitry is to extract a feature amount of the operating sound collected by the sound collector, and determine, at different positions in the sheet conveyance direction based on the feature amount, whether an abnormal conveyance of the sheet occurs until the sheet is conveyed to a given position in the sheet conveyance direction.

  • Publication number: 20230193315
    Abstract: Disclosed are methods for performing transcription-dependent directed evolution (TRADE) and novel AAV capsids selected using such methods. This disclosure also provides novel AAV capsid mutants. TRADE technology was used to identify novel AAV vectors that mediate neuronal transduction in the brain following intravenous administration. Application of TRADE in vivo resulted in the identification of new AAV capsids that can transduce neurons more efficiently and more specifically than AAV9 in the brain following administration of the new AAV capsids. The disclosed methods may be used to identify AAV capsids that target various cell populations.

  • Patent number: 11572637
    Abstract: Disclosed herein are methods of high-throughput mapping of viral neutralizing antibody epitopes. Also disclosed are in vitro immunoprecipitation-based adeno-associated virus Barcode-Seq-based methods of mapping viral neutralizing antibody epitopes. In some embodiments, a method of high-throughput mapping of viral NtAb conformational epitopes can be utilized, which may comprise HP scanning of mutant viral libraries, immunoprecipitation (IP), and/or next-generation sequencing (NGS) technology. In some embodiments, a method of identifying one or more dominant epitopes in a viral vector may comprise contacting a mutant capsid of a virus with serum from a subject previously exposed to the virus and immunoprecipitating serum immunoglobulins from the serum. In various embodiments, the viral vector may be an AAV vector.

  • Publication number: 20220332798
    Abstract: The present disclosure relates to methods of producing monoclonal antibodies in animals. In particular, the disclosure provides a method of producing, in vivo, antibodies against viral capsids (VCs) derived from a non-enveloped virus (NEV). The method includes administering to a subject, by hydrodynamic-based transfection, a first set of genetic material encoding NEV structural proteins to induce the subject's intracellular translation and assembly of the proteins into viral capsids. The method also includes administering a second set of genetic material encoding NEV non-structural proteins to facilitate the intracellular assembly of the NEV structural proteins. Thus, this method may be used to produce subject-generated antibody-producing cells that secrete anti-VC antibodies that may be harvested and screened for monoclonal anti-VC antibodies.

  • Publication number: 20220320620
    Abstract: Disclosed is a method for separating a first member (1) and a second member (2) joined to each other comprising the steps of placing a clamp ring (14) on the surface of the first member, plunging a rotating probe (17) having a screw thread on a peripheral surface thereof into the surface of the first member through a through hole (10) of the clamp ring until a tip end of the probe reaches beyond an interface between the first member and the second member, the screw thread being directed so as to lift material of the bonded part away from the second member as a lifted part. The two members can be rejoined to each other by collapsing the lifted part into a bonded part once again by using a rotating probe and a clamp ring.
