Abstract: The present disclosure relates to the technical field of gene engineering, and in particular, to use of miR-22-3p in promoting the differentiation of yak myoblasts. miR-22-3pmimic can significantly promote the expression of miR-22-3p, and can also significantly increase the expression of differentiation marker genes MYF5 and MYOD at the mRNA and protein levels. miR-22-3p inhibitor can significantly inhibit the expression of miR-22-3p, and can significantly promote the expression of MYF5 and MYOD at the mRNA and protein levels. miR-22-3p mimic can significantly promote the formation of myotubes, while miR-22-3p inhibitor can significantly inhibit the formation of myotubes. The above results indicate that miR-22-3p has a promoting effect in the differentiation process of myoblasts.

Abstract: The present application describes an intelligent hoisting method for a bridge deck crane system. The method involves determining the splicing heights at two key positions of the segment to be installed by measuring the alignment height of an already installed segment. The segment is hoisted, and the real-time heights at both positions are monitored. If one position reaches the splicing height while the other does not, the lifting point is adjusted until both positions align with their respective splicing heights. This method eliminates the need for reference marks or docking joints on the segment to be installed, thereby avoiding issues related to their precision and installation accuracy. Additionally, it simplifies the splicing operation by removing the need for pre-processing the segment, reducing the overall complexity of the process.
