1Cultural Treasure Tibet Autonomous Region, China显示文摘Dancers perform Jiuhe Zhuo Dance in Lhasa City, southwest China’s Tibet Autonomous Region, on July 17. As a special art of Tibetan traditional dance, Jiuhe Zhuo Dance has a history of more than 1,300 years. The dance performance has also become an important means for local people to shake off poverty.Zhan Yan 2020ChinAfrica2020,12,8:0
2Numerical modeling of tectonic stress field and fault activity in North China显示文摘On the basis of a 3-dimension visco-elastic finite element model of lithosphere in North China,we numerically simulate the recent mutative figures of tectonic stress field.Annual change characteristics of stress field are:1)Maximum principal tensile stress is about 3-9 kPaa-1 and its azimuth lie in NNW-SSE.2) Maximum principal compressive stress is about 1-6 kPaa-1 and its azimuth lie in NEE-SWW.3)Maximum principal tensile stress is higher both in the west region and Liaoning Province.4)Variation of tectonic stress field benefits fault movement in the west part and northeast part of North China.5)Annual accumulative rates of Coulomb fracture stress in Tanlu fault belt have segmentation patterns:Jiashan-Guangji segment is the highest(6 kPaa-1),Anshan-Liaodongwan segment is the second(5 kPaa-1),and others are relatively lower(34 kPaa-1).Li Yan Chen Lianwang Zhan Zimin 2012Geodesy and Geodynamics2012,3,1:2

14Effects of cotransplantated Schwann cells and neural stem cells in a rat model of Alzheimer's disease显示文摘Schwann cells (SCs) are significantly better at promoting neural stem cell (NSCs) proliferation, differentiation and synaptic formation when cocultured with NSCs in vitro, compared with cultured in a single nerve growth factor. The present study transplanted NSCs and SCs into the brain of a rat model of Alzheimer's disease to investigate the effect of cotransplantation. Results show transplantation of both NSCs alone and NSCs + SCs significantly promoted learning and memory functions in Alzheimer's disease rats, decreased glial fibrillary acidic protein and calcium binding protein S100β expression, but increased expression of the cholinergic neuron marker choline acetyl transferase mRNA. The effect of NSCs + SCs cotransplantation was, however, more significant. NSCs and SCs cotransplantation significantly reduced the number of astrocytes and increased cholinergic neurons, facilitating the recovery of learning and memory function, compared with NSCs transplantation alone.Yan Zhan Dihui Ma Yu Zhang 2011Neural Regeneration Research2011,6,4:13
15Spreading of human neutrophils on an ICAM-1-immobilized substrate under shear flow显示文摘Neutrophil (PMN) spreading on endothelium, mediated by the interactions between surface-bound β2 integrin and intercellular adhesion molecule-1 (ICAM-1) in the inflammatory cascade, is crucial for PMN post-adhesion and trans-migration in blood flow. The underlying mechanisms by which shear flow regulates PMN spreading dynamics are not well understood. Here, a parallel-plate flow chamber assay was applied to quantify the time course of PMN adhesion and spreading on an ICAM-1-immobilized substrate. Two types of shear flow, steady flows at shear stresses of 0.2, 0.5, and 1 dyne/cm2 and stepwise flows at 0, 1, and 10 dyne/cm2, were used to elucidate the impact of shear flow on cell adhesion and spreading. The number of adhered PMNs, the fraction of spreading PMNs and the projected area of spread PMNs were determined and were found to correlate with the distribution of surface-bound β2 integrin subunit (CD11a, CD11b, or CD18). The results indicate that PMN spreading on an ICAM-1 substrate is bi-directionally regulated under shear flow. CD11a, CD11b and CD18 subunits of β2 integrin contribute distinctly to PMN spreading on ICAM-1 substrates. This work provides new insights into understanding PMN spreading on the endothelium, mediated by β2 integrin and ICAM-1 under shear flow.ZHAN DongYing ZHANG Yan LONG Mian 2012Chinese Science Bulletin2012,57,7:2
