| 1 | CRISPR/Cas9-mediated gene editing in human tripronuclear zygotes显示文摘染色体编辑工具例如定期聚类短 palindromic 重复(CRISPR ) 联系了的 interspaced 系统(Cas ) 广泛地被用来包括动物接合子和人的房间在模型系统修改基因,并且为基本研究和临床的应用保持巨大的诺言。迄今为止,严肃的知识差距在人的早胚胎,并且在效率和在人的培植前胚胎使用象 CRISPR/Cas9 那样的技术的潜在的离开目标效果留在我们 DNA 修理机制的理解。在这份报告,我们使用了推进的接合子调查 CRISPR/Cas9-mediated 基因在人的房间编辑的 tripronuclear (3PN ) 。我们发现 CRISPR/Cas9 能有效地劈开内长的 -globin 基因(HBB ) 。然而,相应再结合的效率指导了 HBB 的修理(HDR ) 是低的,编辑胚胎是马赛克。离开目标劈开在由 T7E1 试金并且 whole-exome 定序揭示了的这些 3PN 接合子也是明显的。而且,内长的 delta-globin 基因(HBD ) 对 HBB 相应,与外长的施主 oligos 竞争了充当修理模板,导致倔强的变化。我们的数据也显示在这些胚胎的 HBB 地点的修理通过非转线路 HDR 小径优先地发生了。一起拿,我们的工作加亮紧迫的需要进一步改进 CRISPR/Cas9 平台的忠实和特性,为编辑的 CRSIPR/Cas9-mediated 的任何临床的应用程序的一个前提。 | Puping Liang Yanwen Xu Xiya Zhang Chenhui Ding Rui Huang Zhen Zhang Jie Lv Xiaowei Xie Yuxi Chen Yujing Li Ying Sun Yaofu Bai Zhou Songyang Wenbin Ma Canquan Zhou Junjiu Huang | 2015 | Protein & Cell2015，6，5： | 149 |
| 2 | Influence of B,Al and Nb addition on the glass forming ability and stability of mechanically alloyed Zr-Ni amorphous alloys显示文摘We investigated the influence of minor additions of B,Al and Nb that have representative atomic sizes on the glass forming ability (GFA) and stability of Zr-Ni amorphous alloys during mechanical alloying. The results show that the minor addition of B,Al or Nb does not shorten the initial time of the full amorphization reaction or improve the glass forming ability of the Zr-Ni alloys at a low rotation speed. However,B addition can effectively improve the mechanical stability of the amorphous phase against mechanically induced crystallization. Furthermore,the amorphous phase gradually transforms into a metastable fcc-phase with increasing milling time. The addition of Al and Nb that have similar atomic sizes has a similar effect on the GFA and the mechani-cal stability of the Zr-Ni amorphous phase. Moreover,Al and Nb addition can alter the crystallization behavior and improve the thermal stability of the Zr-Ni amorphous phase. | WANG Yan DING JunFeng BAI YanWen | 2011 | Chinese Science Bulletin2011，56，36： | 5 |
| 3 | Diagnostic value of negative enrichment and immune fluorescence in situ hybridization for intraperitoneal free cancer cells of gastric cancer显示文摘Objective:To explore the intraperitoneal free cancer cell(IFCC)detection value of negative enrichment and immune fluorescence in situ hybridization(NEimFISH)on chromosomes(CEN)8/17.Methods:To verify the reliability of NEimFISH,29 gastric cancer tumors,their adjacent tissues and greater omental tissues were tested.Our study then included 105 gastric cancer patients for IFCC.We defined patients as IFCC-positive if a signal was detected,regardless of the detailed cancer cell numbers.A comparison of clinicopathological features was conducted among IFCC groups.We also compared the diagnosis value and peritoneal recurrence predictive value among different detection methods.The comparison of IFCC number was also conducted among different groups.Results:A cutoff of 2.5 positive cells could distinguish all benign tissue samples and 97%of malignant tissue samples in our study.Compared to intestinal gastric cancer,patients with diffuse gastric cancer tended to have more IFCCs(6 vs.4,P=0.002).The IFCC counts were often higher in the lymphovascular invasion positive group than negative group(3 vs.1,P=0.022).All IFCC samples that were considered positive using conventional cytology were also found to be positive using NEimFISH.When compared to conventional cytology and paraffin pathology,NEimFISH had a higher IFCC positive rate(68.9%)and higher one-year peritoneal recurrence predictive value with area under the curve(AUC)of 0.922.Conclusions:Gastric cancer could be effectively diagnosed by NEimFISH.The IFCC number found using NEimFISH on CEN8/17 is closely associated with Lauren type and vascular invasion of cancer.NEimFISH is a reliable detection modality with a higher positive detection rate,higher one-year peritoneal recurrence predictive value and quantitative features for IFCC of gastric cancer. | Anqiang Wang Zhongwu Li Qian Wang Yali Bai Xin Ji Tao Fu Ke Ji Yanwen Xue Tingxu Han Xiaojiang Wu Ji Zhang Yingjie Yang Guobin Xu Zhaode Bu Jiafu Ji | 2019 | Chinese Journal of Cancer Research2019，31，6： | 3 |
| 4 | Operando X-ray diffraction analysis of the degradation mechanisms of a spinel LiMn2O4 cathode in different voltage windows显示文摘The understanding of reaction mechanisms of electrode materials is of significant importance for the development of advanced batteries.The LiMn2O4 cathode has a voltage plateau around 2.8 V(vs.Li^+/Li),which can provide an additional capacity for Li storage,but it suffers from a severe capacity degradation.In this study,operando X-ray diffraction is carried out to investigate the structural evolutions and degradation mechanisms of LiMn2O4 in different voltage ranges.In the range of 3.0-4.3 V(vs.Li^+/Li),the LiMn2O4 cathode exhibits a low capacity but good cycling stability with cycles up to 100 cycles and the charge/discharge processes are associated with the reversible extraction/insertion of Li^+from/into LixMn2O4(0≤x≤1).In the range of 1.4-4.4 V(vs.Li^+/Li),a capacity higher than 200 mAh/g is achieved,but it rapidly decays during the cycling.The voltage plateau around 2.8 V(vs.Li^+/Li)is related to the transformation of the cubic LiMn2O4 phase to the tetragonal Li2Mn2O4 phase,which leads to the formation of cracks as well as the performance degradation. | Fakui Luo Congcong Wei Chi Zhang Hui Gao Jiazheng Niu Wensheng Ma Zhangquan Peng Yanwen Bai Zhonghua Zhang | 2020 | Journal of Energy Chemistry2020，29，5： | 2 |

| 6 | Deep graph learning for spatially-varying indoor lighting prediction显示文摘Lighting prediction from a single image is becoming increasingly important in many vision and augmented reality(AR)applications in which shading and shadow consistency between virtual and real objects should be guaranteed.However,this is a notoriously ill-posed problem,especially for indoor scenarios,because of the complexity of indoor luminaires and the limited information involved in 2D images.In this paper,we propose a graph learning-based framework for indoor lighting estimation.The core is a new lighting model(DSGLight)based on depth-augmented spherical Gaussians(SGs)and a graph convolutional network(GCN)that infers the new lighting representation from a single low dynamic range(LDR)image of limited field-of-view.Our lighting model builds 128 evenly distributed SGs over the indoor panorama,where each SG encodes the lighting and the depth around that node.The proposed GCN then learns the mapping from the input image to DSGLight.Compared with existing lighting models,our DSGLight encodes both direct lighting and indirect environmental lighting more faithfully and compactly.It also makes network training and inference more stable.The estimated depth distribution enables temporally stable shading and shadows under spatially-varying lighting.Through thorough experiments,we show that our method obviously outperforms existing methods both qualitatively and quantitatively. | Jiayang BAI Jie GUO Chenchen WANG Zhenyu CHEN Zhen HE Shan YANG Piaopiao YU Yan ZHANG Yanwen GUO | 2023 | Science China(Information Sciences)2023，66，3： | 0 |
