Abstract: An electric lift device includes a support assembly, a rail, a lifting column, a seat assembly and a driving component. The rail is provided on the support assembly. The lifting column is coaxially sleeved on the rail, and is configured to ascend and descend along an axis of the rail. The seat assembly is connected to the lifting column. The driving component is provided at the support assembly, and is configured to drive the lifting column to ascend and descend relative to the rail so as to drive the seat assembly to ascend and descend. The rail is inclined at a preset angle relative to the support assembly towards a side away from the seat assembly.

Abstract: A foldable scooter includes a handle assembly, a bearing assembly, a support assembly, a seat, a clamp assembly, and a locking assembly. The support assembly is articulated with the bearing assembly, such that it can be rotated relative to the support assembly to fold or unfold the scooter. The seat is removably provided on the support assembly. The clamp assembly is spacedly provided with a first groove and a second groove. The locking assembly is rotatably provided on the bearing assembly, and can be clamped in the first groove or the second groove to realize the locking of the scooter in an unfolded or folded state.

Abstract: A folding scooter, including a handle assembly, a support plate assembly, a seat and a connecting assembly. The seat is detachably provided on the support plate assembly. The connecting assembly is configured to achieve the rotational connection between the handle assembly and the support plate assembly. The connecting assembly includes a connecting plate, a hinge shaft and a fixing plate. In this application, the hinge shaft is located below the support plate assembly, such that when the folding scooter is folded, the rotational axis of the handle assembly is located below the support plate assembly, thereby enabling the handle assembly to closely cling to the support plate assembly.

Abstract: The present disclosure concerns embodiments related to methods of enriching particular DNA for analysis of methylation status and/or profiles, for example in the process of diagnosis of cancer. In particular embodiments, the methods utilize cell-free DNA as a source of DNA instead of genomic DNA and allow for focused enrichment of fragments having two or more enzyme digestion sites and containing at least one CpG site.

Abstract: Provided is a magnetically fastening apparatus. The magnetically fastening apparatus includes a zipper tab and a lock body. The zipper tab can fit with the lock body by magnetic attraction. The lock body is provided with a control member. The control member has a locking position and an unlocking position. The zipper tab can fit with the lock body by magnetic attraction when the control member is in the locking position. The zipper tab and the lock body are configured to release the magnetic attraction relationship between the zipper tab and the lock body when the control member is in the unlocking position.

Abstract: The present invention provides the cloning of intron-containing Amaranthus caudatus agglutinin (ACA) gene from Amaranthus caudatus and the coding region gene sequence encoding the ACA protein. The said gene sequence of the ACA gene coding region was ligated with highly efficient and stable microbial expression vectors to produce the ACA protein using microbe largely. High expression of the ACA gene can make the transgenic plants have antiaphid activity and improve the nutrition quality thereof. The ACA gene has potential application value in plant anti-insect gene engineering and quality improvement.
