Abstract: A stent (100) that is sleeved and radially expandable, and which in an expanded state provides a breathable, generally tubular structure sized and shaped for residence in a sinus or nasal cavity or passage, and in an unexpanded state has a cross-sectional diameter suitable for insertion into such cavity or passage. The sleeve limits expansion and outward pressure exerted by the stent and thereby can prevent or reduce the incidence of headache in patients, and can provide increased surface area for improved elution of drugs to nearby mucosal tissue.

Abstract: A method for preparing a molecular sieve SCR (selective catalytic reduction) catalyst and a prepared catalyst therethrough. In the method, several molecular sieves are mixed and modified by transition metal or rare-earth metal via ion exchange, then loaded Fe by equivalent-volume impregnation, and loaded Cu by one or more liquid ion exchange. This present invention, combined with several techniques, such as modification of stable molecular sieve by transition and rare-earth metal, Fe loading by equivalent-volume impregnation and Cu loading by one or more liquid ion exchange, and after through stable and effective modification and loading control, the obtained catalyst material is coated on a carrier substrate via size mixing and coating process to be prepared into an integral catalyst.

Abstract: Implants are placed in turbinate mucosal tissue using a surgical device having a proximal grip portion and a distal hollow sharp needle portion that is manipulated using the grip portion and inserted submucosally into mucosal turbinate tissue. One or more biodegradable, drug-eluting solid implants are disposed within the needle. The implants have one or more implant withdrawal-discouraging, mucosal tissue-engaging surface features along their length. An actuator disposed within the device is used to deliver one or more of the implants from the needle into the mucosal turbinate tissue and submucosally bury at least one such tissue-engaging feature therein.

Abstract: A sensor assembly, a force detection device and method, and construction machinery, the sensor assembly comprising a connecting part used for connecting a base to be tested and a bearing part used for bearing, the bearing part being connected to the connecting part, the bearing part comprising at least two sensing units with different measuring ranges, and the at least two sensing units being arranged to have a different initial gap (b1, b2) from the connecting part, so that corresponding initial gap (b1, b2) are eliminated when a load applied to the bearing part reaches different extents. The different initial gaps (b1, b2) are eliminated by means of the load reaching a different extent, so that the sensing units with different measuring ranges can provide detection feedback in the respective working conditions in which the units have the highest measurement precision and thereby ensure the accuracy of detection results.

There are a total of 50,000 SNP loci on the chip: including 19,600 SNP loci for white-feather broilers, yellow-feather and partridge chickens having a MAF value greater than 0.05 and uniformly distributed across the genome which were derived from the data of the whole-genome resequencing of main indigenous chicken breeds in China and introduced chicken breeds; 14,000 SNP loci associated with economic traits, and 16,400 SNP loci for making up for the genomic regions that are not covered by the first two types of probes. The 50,000 SNP loci on the chicken whole-genome SNP chip of the present invention have DNA sequences represented by SEQ ID NOs. 1 to 50,000.

Abstract: The present disclosure provides a Wnt family member 4/tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (Wnt4/YWHAZ) co-modified mesenchymal stem cell (MSC)-derived exosome, and a preparation method and use thereof, belonging to the technical field of skin repair. In the present disclosure, the MSC-derived exosome is modified by overexpressing adenovirus vectors expressing a Wnt4 gene and a YWHAZ gene in the MSCs, such that the exosome overexpresses the Wnt4 gene and the YWHAZ gene, to achieve a medicinal purpose of promoting regeneration and repair of a scalded skin tissue in a rat with the MSC-derived exosome.
