Abstract: An airflow apparatus includes an air tunnel, a fan motor, a fan blade, a box housing and two expandable side units. The fan blade is driven by the fan motor for moving air moving in the air tunnel. The box housing encloses the fan motor, the fan motor and the fan blade. The box housing has multiple fixing units for fixing to a bracket when the box housing is place upon the bracket for limiting movement of the box housing in a first installation mode. The two expandable side units are attached to a lateral side of the box housing. The expandable side units have extending portions extending respectively from two opposite peripheral edges of the box housing. There is an ear hole for each expandable side unit for inserting a fixing hook placed on an installation wall surface in a second installation mode.

Abstract: Provided is a home gateway service identification method, device and system, and the method includes: judging an access destination address of a terminal connected with the home gateway by a home gateway so as to identify the type of a service initiated by the terminal; if it is identified that the service initiated by the terminal belongs to IPTV services, routing the service to an IPTV network by the home gateway; and if it is identified that the service initiated by the terminal belongs to Internet services, forwarding the service to an Internet by the home gateway, and binding all remaining interfaces except the interfaces used by the terminal carrying the IPTV services with a public network. Two or more services can be accessed at the same time at one interface, the requirement of accessing a plurality of services at the same time by the television is met.

Abstract: The present invention relates to a nucleic acid construct comprising a UTR and use thereof. Specifically, the UTR can significantly improve the expression efficiency of a target gene in the nucleic acid construct. The nucleic acid construct may comprise a nucleic acid sequence expressing, for example, a human hepatocyte growth factor (hHGF), and can be used in a gene therapy for serious lower limb ischemia, diabetic foot, and other diseases.

Abstract: Provided in the present invention are a splint nucleic acid molecule for cyclizing a single-stranded nucleic acid molecule and an application therefor. The splint nucleic acid molecule is composed of a 5? terminal fragment and a 3? terminal fragment, the 5? terminal fragment being adapted to forming a first complementary region with a 5? terminal of the single-stranded nucleic acid molecule, and the 3? terminal fragment being suited to forming a second complementary region with a 3? terminal of the single-stranded nucleic acid molecule, the length of the first complementary region and the second complementary region being different.

Abstract: A method and (portable) device are provided for quantifying liver steatosis. The quantitative assessment of liver steatosis predicts whether a liver from the liver transplant donor is suitable for transplantation. Specifically, the quantitative assessment of liver steatosis predicts an associated risk for early allograft dysfunction. A biopsy image from a liver transplant donor is obtained from an automatic quantitative assessment of liver steatosis is made using a pre-trained artificial intelligence algorithm for identifying parameters of liver steatosis. The biopsy image is input to the pre-trained artificial intelligence algorithm. The quantitative assessment of liver steatosis is the output of the pre-trained artificial intelligence algorithm. Embodiments provide for rapidly diagnosing potential donor liver allografts at the time of procurement with a point-of-care device deployed with the transplant surgery team.
