Aculeus type tissue slice glassivation refrigeration carrier and refrigeration method for ovary tissue

An acupuncture-type tissue slice vitrification freezing carrier is composed of a freezing tube with one end being closed and the other end being open, and an acupuncture device. The acupuncture device comprises a needle head and a needle disposed on the needle head and used for threading tissue slices. A section matching with the internal shape and size of the open end of the freezing tube is disposed on the needle head. After the acupuncture device and the freezing tube are combined, the needle is positioned in the freezing tube, and the needle head is adopted as a tube plug of the freezing tube to seal the open end of the freezing tube. A plurality of tissue slices (such as ovary tissue slices and liver tissue slices) can be threaded in a row on the needle at intervals by the carrier so as to be subjected to each operation of the vitrification freezing and storage, and a plurality of sample tissues can be subjected to the vitrification freezing and storage simultaneously, with simple ...

Antisense nucleotide targeting circRNA (Ribonucleic Acid) and application of antisense nucleotide in resisting pulmonary arterial hypertension

The invention belongs to the technical field of medical biology, and discloses a targeting circRNA (Ribonucleic Acid) antisense nucleotide hsa-circRNA-026272-siRNA (Small Interference Ribonucleic Acid), and a pharmaceutically acceptable carrier or a virus carrier and an auxiliary material thereof. The pharmaceutical composition is used for, but not limited to, low-oxygen environments, chronic thromboembolism, drug induction and pulmonary arterial hypertension caused by secondary congenital heart diseases. It is found that the hsa-circRNA-026272-siRNA can significantly inhibit proliferation and migration of pulmonary artery smooth muscle cells and improve heart and lung hemodynamic changes and heart and lung vascular remodeling induced by monocrotaline. The invention provides a safe, effective and economical solution for treating and preventing pulmonary arterial hypertension and complications thereof.

Transport layer protocol implementation method on programmable switch

The invention relates to the technical field of network information, and discloses a transmission layer protocol implementation method on a programmable switch, which comprises the following steps of: distinguishing TCP (Transmission Control Protocol) streams; a TCP finite-state machine; application layer support; and retransmission of the data packet. According to the transmission layer protocol, establishment and release of TCP connection and data transmission are achieved on the data plane of the programmable switch, the characteristic of line speed forwarding of the programmable switch is utilized, time delay of TCP connection and transmission is reduced, and application time delay is reduced. According to the transmission layer protocol, TCP modification and customization can be carried out on the programmable switch, and compared with modification of a TCP protocol stack on a server (a user side), the method has the advantages of being rapid in deployment and easy to scale. The original ...

Hole drilling method for single or dual curved plate

Purification system and method for electrolytic hydrogen production

The invention relates to the technical field of hydrogen production by electrolysis of water, in particular to a purification system for hydrogen production by electrolysis, which comprises: an electrolytic bath for electrolyzing water to generate to-be-treated low-purity hydrogen carrying alkali liquor; the gas-liquid separation device is used for treating the low-purity hydrogen carrying the alkali liquor to obtain hydrogen to be purified; the purification module comprises a first purification unit, a second purification unit, a buffer tank and a valve for controlling the gas flowing direction; the hydrogen in the hydrogen to be purified is separated by using the selective reversible hydrogen absorption/evolution material, the energy consumption is saved, the purification efficiency of the electrolytic hydrogen production is improved, and the purification process of the electrolytic hydrogen production is simplified by controlling the switching of the valve through the PLC.

Castor oil foamed sponge and preparation process thereof

The invention discloses castor oil foamed sponge. The castor oil foamed sponge is prepared from the following components: 20 to 25 parts of butter (P), 20 to 25 parts of white oil (O), 25 to 30 parts of castor oil, 25 to 30 parts of TDI (toluene diisocynate) T80, 1 to 5 parts of silicone oil, 1 to 5 parts of A-33 and 1 to 5 parts of T-9. According to the castor oil foaming sponge disclosed by the invention, the dispersity among the components is improved by adding a preset amount of castor oil into the raw material components, and the mixing uniformity among the components can be greatly improved by adding the castor oil into the foaming sponge, so that the full proceeding of a cross-linking reaction among the butter, the white oil and the TDI T80 is promoted; and the yield of foamed sponge products is further improved. According to the preparation process of the castor oil foamed sponge, the stirring device is controlled to mix and stir the mixture through production parameters set by ...
