2results about How to "Reduce viral load" patented technology

This application discloses a short peptide PRP1, its preparation method, and its application. It belongs to the field of genetic engineering technology. This application identifies a short peptide derived from an unknown protein that can regulate tobacco resistance to Potato Virus Y (PVY), named PVY resistance peptide (PRP1). Its amino acid sequence is ATKHIVGSIVAS. The short peptide PRP1 was prepared through chemical synthesis. Injecting this short peptide into tobacco seedlings can effectively reduce PVY virus levels and improve tobacco resistance to PVY.

The invention provides an air purification device for a hog house, and belongs to the technical field of livestock breeding. The hog house air purification device comprises a hollow cuboid-shaped purification box body, a hollow cylindrical net cage rotary drum, an air pipe, an ultraviolet lamp tube and a polystyrene foam ball net cage rotary drum which are located in the purification box body; and the mesh cage rotary drum is connected with a power output shaft of a driving motor arranged on the outer side of the purification box body. The air pipe extends near the inner side of the end face of the closed end of the cylinder mould drum. And the ultraviolet lamp tubes are respectively arranged at the axial center position in the air pipe and at four corners of the purification box body outside the cylinder mould rotary drum. And the polystyrene foam balls are filled in an area between the outer side of the air pipe and the cylinder mould drum. The hog house air purification device is simple in structure, the friction electrostatic adsorption technology and the ultraviolet secondary disinfection technology are combined, the number of viruses carried in air in a hog house is reduced, and the disease incidence probability of hogs is reduced.
