3Effects of neurotrophin-3 on the differentiation of neural stem cells into neurons and oligodendrocytes显示文摘In this study,cells from the cerebral cortex of fetal rats at pregnant 16 days were harvested and cultured with 20 μg/L neurotrophin-3.After 7 days of culture,immunocytochemical staining showed that,22.4% of cells were positive for nestin,10.5% were positive for β-III tubulin(neuronal marker),and 60.6% were positive for glial fibrillary acidic protein,but no cells were positive for O4(oligodendrocytic marker).At 14 days,there were 5.6% nestin-,9.6% β-III tubulin-,81.1% glial fibrillary acidic protein-,and 2.2% O4-positive cells.In cells not treated with neurotrophin-3,some were nestin-positive,while the majority showed positive staining for glial fibrillary acidic protein.Our experimental findings indicate that neurotrophin-3 is a crucial factor for inducing neural stem cells differentiation into neurons and oligodendrocytes.Guowei Zhu Chongran Sun Weiguo Liu 2012Neural Regeneration Research2012,7,19:0
4Modeling Study of Foehn Wind Events in Antarctic Peninsula with WRF Forced by CCSM显示文摘Significant changes have occurred in the Antarctic Peninsula(AP) including warmer temperatures, accelerated melting of glaciers, and breakup of ice shelves. This study uses the Weather Research and Forecasting model(WRF)forced by the Community Climate System Model 4(CCSM) simulations to study foehn wind warming in AP. Weather systems responsible for generating the foehn events are two cyclonic systems that move toward and/or cross over AP. WRF simulates the movement of cyclonic systems and the resulting foehn wind warming that is absent in CCSM. It is found that the warming extent along a transect across the central AP toward Larsen C Ice Shelf(LCIS) varies during the simulation period and the maximum warming moves from near the base of leeward slopes to over 40 km away extending toward the attached LCIS. Our analysis suggests that the foehn wind warming is negatively correlated with the incoming air temperature and the mountain top temperature during periods without significant precipitation, in which isentropic drawdown is the dominant heating mechanism. On the other hand, when significant precipitation occurs along the windward side of AP, latent heating is the major heating mechanism evidenced by positive relations between the foehn wind warming and 1) incoming air temperature, 2) windward precipitation, and 3)latent heating. Foehn wind warming caused by isentropic drawdown also tends to be stronger than that caused by latent heating. Comparison of WRF simulations forced by original and corrected CCSM data indicates that foehn wind warming is stronger in the original CCSM forced simulation when no significant windward precipitation is present.The foehn wind warming becomes weaker in both simulations when there is significant windward precipitation. This suggests that model's ability to resolve the foehn warming varies with the forcing data, but the precipitation impact on the leeward warming is consistent.Chongran ZHANG Jing ZHANG 2018Journal of Meteorological Research2018,32,6:0
5High-lattice-adapted surface modifying Na_(4)MnV(PO_(4))_(3) for better sodium storage显示文摘Sodium-ion batteries(SIBs)are required to possess long cycle life when used for large-scale energy storage.The polyanionic Na_(4)MnV(PO_(4))_(3)(NMVP)reveals good cyclic stability due to its unique three-dimensional(3D)frame structure,but it still faces the challenge of interfacial degradation in practical applications.In this work,NASICON-type Na_(1.3)Al_(0.7)Ti_(1.3)(PO_(4))_(3)(NATP)was deposited on the surface of NMVP to promote interface stability by surface modification and gradient doping.As a result,the optimized NMVP@2%NATP released a capacity retention of 44.8%after 1000 cycles at 5 C,much higher than that of the initial NMVP(28.9%).The enhanced electrochemical performance was mainly attributed to NATP coating acting as a fast ion transport carrier and physical barrier,significantly facilitating the Na^(+)diffusion and isolating side reaction at the electrode/electrolyte interface.On the other hand,Ti_(4)^(+)and Al^(3+)cations from the NATP were partially doped inside the NMVP surface to boost the transport of Na^(+),and the perfect lattice matching of NVMP and NATP improved the interface and structural stability accompanying long cycling.This work demonstrated the effectiveness of surface modification with high lattice match material and provided new perspectives for high energy density solid-state SIBs.Chongran Song Shiyu Li Ying Bai 2024Nano Research2024,17,4:0
