Publication number: 20220378892Abstract: The present invention relates to methods for the recombinant expression of chlamydia major outer membrane protein (MOMP) comprising transforming a population of E. coli host cells with an expression vector comprising a nucleic acid molecule that encodes chlamydia MOMP and encodes a leader sequence for targeting the MOMP to the outer membrane of the cell, wherein the nucleic acid molecule is operatively linked to a promoter. The method of the invention allows expression of MOMP in the outer membrane of the cell, which leads to protein folding that is more like native MOMP relative to a MOMP protein that is expressed intracellularly. Also provided by the invention are uses of the recombinant MOMP in pharmaceutical compositions and methods for the treatment and/or prophylaxis of chlamydia infection and/or the effects thereof.Type: ApplicationFiled: July 1, 2022Publication date: December 1, 2022Applicant: Merck Sharp & Dohme LLCInventors: Lan Zhang, Zhiyun Wen, Craig T.

Publication number: 20200353546Abstract: A jig saw including a clamping mechanism for removably clamping a saw blade and a driving mechanism. The clamping mechanism includes an actuating member and a clamping mechanism, the actuating member is configured to rotate about a first axis, thereby driving the clamping mechanism to achieve locking or unlocking of the saw blade. The actuating member includes an inclined surface extending in a rotation direction of the actuating member. The inclined surface cooperates with the clamping mechanism thereby to drive the clamping mechanism when the actuating member rotates. Since the clamping mechanism of the jig saw uses a clamping mechanism to apply pressure to the saw blade from the side, thereby abutting and fixing it on the main body, such a clamping mechanism therefore can be applied to different types of saw blades, regardless of the shape of the end faces of their clamping ends (e.g., V-shaped or U-shaped).Type: ApplicationFiled: May 6, 2020Publication date: November 12, 2020Inventors: Lei HU, Xiao Ping QIU, Ji Zhou YAN

Patent number: 9839816Abstract: A ball pickup device is provided, comprising a ball collector and a pull rod connected to the ball connector. The ball collector has ball inlets formed at the bottom of the ball collector and formed by transverse rods arranged at the bottom of the ball collector in parallel at intervals, and one ball outlet is formed by the interval between every two adjacent transverse rods. Each interval is smaller than the diameter of a ball. One end of each transverse rod is fixedly connected to the ball collector, and the other end is a movable end and located in the corresponding receding groove. When a ball is pressed, movable ends move along receding grooves to recede under the pressure of the ball, and the ball enters the ball collector. After the ball enters the ball inlet, movable ends move along receding grooves to gradually return.Type: GrantFiled: May 22, 2015Date of Patent: December 12, 2017Inventor: Ping Qiu
