Main experiments in the start phase will be involved with breakdown and plasma current set-up with a mode of saving volt-second and without ohmic heating system, equilibrium and instability, current driving, heating and profile modification. The SUNIST is a university-scale conceptual spherical tokamak, with R = 0.3 m, A 1.3, Ip - 50 kA, BT < 0.15 T, and PRF - 100 kW. The only peculiarity of SUNIST is that there is a toroidal insulating break along the outer wall of vacuum vessel. The expected that advantages of this arrangement are helpful not only for saving flux swing, but also for having a deep understanding of what will influence the discharge startup and globe performances of plasma under different conditions of strong vessel eddy and ECR power assistance. Of course, the vessel structure of cross seal will be at a great risk of controlling vacuum quality, although we have achieved positive results on simulation test and vacuum vessel test.展开更多

Based on the Requirements for Ethical Review of Biomedical Research Involving Human, ethical review system for Chinese medicine research was established and standardized from 4 aspects, such as organization, ethics committee, office of the ethics committee, and researchers. The period of CAP certification is three years, which include certification application and acceptance, initial certification(document review, on-site audit), certification decision, and supervision audit. The implementation of the CAP certification is of great importance for upgrading the research on ethics review system of Chinese medicine, which promotes the development of the research on ethics review system in China and the continuous improvement of the ability of the Chinese medicine research on ethics review.展开更多

Mashl and Brn2 have been previously shown to cooperate to reprogram fibroblasts into neurons. In this study, we examined astrocytes from 2-month-old Sprague-Dawley rats, and found that Brn2 was expressed, but Mashl was not detectable. Thus, we hypothesized that Mashl alone could be used to reprogram astrocytes into neurons. We transfected a recombinant MSCV-MASH1 plasmid into astrocytes for 72 hours, and saw that all cells expressed Mashl. One week later, we observed the changes in morphology of astrocytes, which showed typical neuro- nal characteristics. Moreover, β-tubulin expression levels were significantly higher in astrocytes expressing Mashl than in control cells. These results indicate that Mashl alone can reprogram astrocytes into neurons.展开更多
