  • Patent number: 11946240
    Abstract: A water outlet box of a pressure-type flushing system and a toilet using the water outlet box, including a water outlet box main body and a first one-way valve assembly. The water outlet box main body is formed with a water-passing cavity, a water inlet, at least one water outlet and a vent, with the water inlet, the water outlet and the vent all connecting with the water-passing cavity. The first one-way valve assembly is provided opposite to the water inlet to open or block the water inlet, and when the pressure-type flushing system finishes flushing, the first one-way valve assembly blocks the water inlet. The vent is provided at the top of the water-passing cavity and is open to the atmosphere. The water outlet box main body is provided with several water inlet pipes in communication with the functional devices of the pressure-type flushing system.

  • Publication number: 20240093185
    Abstract: DNA molecules for making a circular RNA are provided. The DNA molecule may include elements operably connected and arranged, from a 5? to 3? direction, in the following order: (a) an intron fragment that includes a full-length intron; (b) an E2 fragment which includes a downstream exon of the full-length intron; and (c) an E1 fragment which includes an upstream exon of the full-length intron. 3? end of the E1 fragment is configured to produce a hydroxyl group in an in vitro transcription reaction; the hydroxyl group is capable of initiating splicing in a one-step transesterification reaction at a splice site between RNA fragments transcribed from the intron fragment and the E2 fragment in a linear RNA that is produced from the DNA molecule in the in vitro transcription reaction, such that the linear RNA is configured to self-circularize to produce the circular RNA.

  • Publication number: 20240085331
    Abstract: An optical detection system, a blood cell analyzer and a platelet detection method are provided. The optical detection system includes: an optical subsystem, a flow chamber and a first detector; the optical subsystem includes a laser, a front optical assembly including an optical isolator, and a rear optical assembly including a blocking diaphragm. The laser is configured to emit a laser beam; the front optical assembly is configured to perform front optical treatment; the rear optical assembly is disposed downstream of the flow chamber in the propagation direction of the laser beam, and is configured to perform rear optical treatment on the scattered light and the laser beam converged at the blocking diaphragm; and the optical isolator is configured to isolate reflected light that is generated when the laser beam passes through the flow chamber.

  • Patent number: 11402383
    Abstract: The present invention belongs to the field of immunology and molecular biology, which relates to an anti-PCSK9 antibody, the pharmaceutical composition and method of use thereof. In particular, the present invention relates to the monoclonal antibody, which can bind PCSK9 specifically, block association of PCSK9 with LDLR, upregulate the amount of LDLR on cell surface, heighten the metabolism of LDL cholesterol and/or triglycerides, and prevent/treat cardiovascular diseases caused by hypercholesterolemia.

  • Publication number: 20220041997
    Abstract: The present invention relates to a new method for rescuing an influenza virus and a composition therefor. The method comprises providing a host cell stably integrated with and expressing influenza virus PA, PB1, PB2 and NP genes, and introducing an influenza virus rescue system in which a stop codon is introduced into the PA, PB1, PB2 and NP genes respectively into the host cell to achieve virus rescue. The produced virus particles can be used as a live attenuated influenza vaccine, which is characterized in that, since the genes encoding the related proteins are mutated, it has no replication and proliferation ability in human and normal animal cells, and replication and proliferation can be achieved only in the host cells constructed above and it can fully stimulate the body immunity and effectively protect the body while ensuring the safety.
