Abstract: A lifting mechanism includes: a cross-arm assembly including a first combined arm and a second combined arm arranged in parallel, the first and second combined arms each comprising a first support member and a second support member, the length of the first support member being greater than the length of the second support member; a support connection assembly including a first rotational connection assembly and a first sliding connection assembly fixed to a base, and a second rotational connection assembly and a second sliding connection assembly fixed to the bottom side of a table top, the first and second sliding connection assemblies each comprising a slide rail and a moving member rotatably and slidably arranged in the slide rail; and a driving member connected to the cross-arm assembly and/or the support connection assembly for driving the moving members to change their position on the slide rail.

Abstract: A flip-folding lift desk includes: a support base, the bottom surface of the support base having at least three support members, the top surface of the support base having a connection seat extending in a direction away from the support members; a lift assembly arranged to rise and fall along its length direction, one end of the lift assembly being rotatably connected to the connection seat, so that the lift assembly can switch between two states in the length direction, including one in which the lift assembly is perpendicular to the support base, and the other in which the lift assembly is parallel to the support base; a rotation locking assembly comprising a fixed disk, a locking block, a rotating disk, a torsion spring, and a driving block; and a top assembly connected to the rotating disk on the rotation locking assembly.

Abstract: The present invention provides a hybrid antimicrobial protein having a strong bactericidal effect and an application thereof. Said hybrid antimicrobial protein having a strong bactericidal effect is a hybrid protein with the amino acid sequence of SEQ ID NO: 1 which named AB469; or a hybrid protein including a sequence similar to a catalytic domain of the AB469, or a hybrid protein including a sequence similar to a binding domain of the AB469; or, a hybrid protein including the catalytic and binding domains with positions interchanged of the AB469.

Abstract: A hand-operated worm gear height adjustable table includes a table top, a base mechanism, a lift mechanism, and a driving mechanism. The base mechanism includes a base and tracks on the base. The lift mechanism includes two parallel first lift arms and two parallel second lift arms which cross with each other to form X-shaped structures. The driving mechanism is connected to the upper ends of the first lift arms and includes two U-shaped slide rails and a driving shaft penetrating through the upper ends of the first lift arms. The center of the driving shaft is provided with a worm gear and a worm. The outer end surface of the worm is sleeved with a first sleeve component and a second sleeve component with a cavity provided therebetween, and the outer end surface of the first sleeve component is sleeved with the first torsional spring.

Abstract: The present invention describes use of spink6 gene and the encoded protein in the manufacture of an anti-tumor drug. spink6 gene has a nucleotide sequence designated as SEQ ID NO:1, and the protein encoded by spink6 gene has an amino acid sequence designated as SEQ ID NO:2. The protein encoded by spink6 gene and its derivatives can be used as potential drugs for treatment of human diseases caused by dysregulation of the cell cycle control, such as various malignant tumors, cell abnormal proliferation, and the like.

Abstract: Disclosed herein is the finding that baculovirus display of multiple influenza virus hemagglutinin (HA) proteins elicits broadly reactive immune responses against influenza. Thus provided herein are recombinant baculovirus vectors having a first, second, third and fourth nucleic acid sequence, each encoding an influenza hemagglutinin (HA) fusion protein. The first, second, third and fourth nucleic acid sequences each encode an influenza HA with a different amino acid sequence. Also provided are recombinant baculoviruses displaying a first, second, third and fourth influenza virus HA fusion protein in the baculovirus envelope, wherein each HA fusion protein comprises a different HA amino acid sequence. Tetravalent influenza virus vaccines comprising the recombinant baculoviruses disclosed herein are further provided. In addition, methods of immunizing a subject against influenza virus using the tetravalent influenza virus vaccines are provided.
