[Establishment of A Mixed Chimeric Mouse Model of Allogeneic Bone Marrow Transplantation and Its Influencing Factors].

Objective: To establish a mouse mixed chimerism (MC) model of nonmyeloablative allogeneic bone marrow transplantation(allo-BMT) and explore its affecting factors.

Methods: The MC model was established by nonmyeloablative allo-BMT followed by high-dose post-transplant cyclophosphamide (PTCY). 123 mice in the experiments was retrospectively analyzed, and the factors related with the chimerism were explored with the univariate and multivariate logistic regression analysis.

Characterization and Function of a Novel Welan Gum Lyase From Marine sp. WG.

Welan gum, a kind of microbial exopolysaccharides, produced by the genus , have great potential for application in many fields, such as the food industry, cement production, and enhanced oil recovery. But there are still challenges to reduce the cost, enhance the production and the quality. Herein, the bioinformatics analysis of gene was preformed, and the characterization and function of WelR, welan gum lyase, from sp.
