摘要:
The present invention provides a method for preparing atosiban acetate. The method comprises the following steps of: synthesizing to obtain linear atosiban; dissolving the linear atosiban in an acetonitrile aqueous solution, adjusting the pH value with ammonia water, adding H2O2 for oxidizing, filtering, purifying, and transferring salt to obtain the atosiban acetate. In the present invention, an appropriate route is provided, the linear atosiban is synthesized by adopting a solid phase method, and the atosiban is obtained by liquid phase oxidation. The method has the advantages of capabilities of solving the problem of insolubility of the linear atosiban, reducing the reaction size to the maximum extent and shortening reaction time, and being high in yield and easy to industrialize.

摘要:
Provided are a sub-totipotent stem cell product and epigenetic modification label thereof, a method for inducing the generation of the sub-totipotent stem cell product and identification for the epigenetic modification label of the differentiation potential of stem cells. Also provided is a use of histone modification states of sub-totipotent genes and/or differentiation related genes to predict the epigenetic modification label of the differentiation potentials of stem cells.
摘要:
A sandal strap reinforcement apparatus which is incorporated into a sandal having a multi-hardness midsole to reinforce the opening around the straps. The apparatus may be made of a molded material, fabric, tape, an o-ring, cord, or the same material as the harder layer. The apparatus is molded into the midsole and serves to protect the hole or slot from damage from a strap inserted through the hole or slot.
