Prior to the generation of hematopoietic stem cells(HSCs)from the hemogenic endothelial cells(HECs)mainly in the dorsal aorta in midgestational mouse embryos,multiple hematopoietic progenitors including erythro-myeloid progenitors and lymphoid progenitors are generated from yolk sac *** HSCindependent hematopoietic progenitors have recently been identified as major contributors to functional blood cell production until ***,little is known about yolk sac ***,combining integrative analyses of multiple single-cell RNA-sequencing datasets and functional assays,we reveal that Neurl3-EGFP,in addition to marking the continuum throughout the ontogeny of HSCs from HECs,can also serve as a single enrichment marker for yolk sac ***,while yolk sac HECs have much weaker arterial characteristics than either arterial endothelial cells in the yolk sac or HECs within the embryo proper,the lymphoid potential of yolk sac HECs is largely confined to the arterial-biased subpopulation featured by the Unc5b ***,the B lymphoid potential of hematopoietic progenitors,but not for myeloid potentials,is exclusively detected in Neurl3-negative subpopulations in midgestational *** together,these findings enhance our understanding of blood birth from yolk sac HECs and provide theoretical basis and candidate reporters for monitoring step-wise hematopoietic differentiation.

This study explored the factors influencing cooperative innovation in environmentally friendly agricultural biotechnology in ***,we constructed an evolutionary game model comprising the factors of net income of cooperative innovation,net income of independent innovation,market constraints,and government *** MATLAB simulation,we assigned different values to the aforementioned variables to explore the evolutionary trend of innovators’willingness to *** showed that when the values of net income of cooperative innovation,net income of independent innovation,market constraints,and government subsidies exceeded the threshold,innovators’willingness to cooperate was significantly ***,the proportion of innovators who cooperated with others gradually increased to 100%;otherwise,it gradually decreased to 0%.Comparing the simulation curve with the real evolution curve of cooperative innovation in agricultural biotechnology in China,we found that the gradual decline in the willingness to cooperate could be due to insufficient subsidies for cooperative innovation,low income from cooperative innovation,weak profitability of innovators,and weak market constraints.

本研究在常规强伸仪上引入了非接触式激光测微模块直接测量单丝炭纤维拉伸时标记物的微小位移,使得新测试系统可以同时准确地测量炭纤维单丝的强度、模量和断裂应变,而无需常规方法中复杂的系统校正.通过对炭纤维T300试样的测试可知,激光测微法的准确性和稳定性优于常规测试方法,并且能清晰地检测到炭纤维在受力过程中存在的非虎克行为.结果表明,激光测微法中标记物作为纤维变形的载体成为准确测量的关键标记,应选择有较好遮光性的材料并且垂直于纤维轴粘贴,标记的测量边最好为线性,在保证一定测量范围的前提下尽可能减小标记尺寸.

从化区作为广州市重要生态屏障,研究从化区突发水环境风险对于保障区域生态环境安全具有重要的理论和现实意义。采用2017年第二次全国污染源普查数据,引入地理信息系统空间分析法,以1 km×1 km的网格为基本单元,对从化区开展突发水环境风险事件评估。结果表明:从化区域整体属于较低风险区域;存在水环境风险值的区域面积约为979 km2,约占评估区域总面积的49.6%。鳌头镇区域风险值最高,其次为太平镇区域。从化区应实行水环境风险分区管控,重点加强鳌头镇、太平镇环境应急能力建设。
