1Estimation of the Effects of Maize Straw Return on Soil Carbon and Nutrients Using Response Surface Methodology显示文摘Straw incorporation is generally considered an effective agricultural management practice that improves nutrient cycling and maintains soil fertility. To study the interactive effects of straw returning factors on soil organic carbon and available nutrients, a17-month(May 6, 2016 to October 6, 2017) experiment was conducted on straw incorporation by using response surface methodology under a three-factor(straw length, amount, and burying depth), five-level quadratic orthogonal rotation experimental design. Weight was assigned to each indicator for soil carbon and nutrients and then a comprehensive indicator was established. Then, a second-order polynomial model of the three straw returning factors was established using response surface methodology. Results indicated that17 months after straw incorporation, straw amount and burying depth had significant effects on the comprehensive indicator of soil carbon and nutrients. Straw length and the interactions of straw amount and burying depth showed no significant effects on the comprehensive indicator of soil carbon and nutrients. It was concluded that 17 months after straw incorporation, the highest value of the comprehensive indicator of soil carbon and nutrients was achieved when the straw length, amount, and burying depth were approximately 17–20 cm, 740–840 g m^(-2), and 9–13 cm, respectively, which can be recommended as the most suitable parameters for use in straw returning in the study area.ZHOU Dongxing SU Ye NING Yucui RONG Guohua WANG Guangdong LIU Di LIU Liyan 2018Pedosphere2018,28,3:12
2TRAP1 Shows Clinical Significance and Promotes Cellular Migration and Invasion through STAT3/MMP2 Pathway in Human Esophageal Squamous Cell Cancer显示文摘Tumor necrosis factor receptor-associated protein 1(TRAP1), an important member of mitochondrial heat shock protein 90 family, is involved in multiple biological processes in several types of tumors. However, its pathological role in esophageal squamous cell cancer(ESCC) remains unknown. Herein, we demonstrated the clinical value of TRAP1, and its role in apoptosis and motility in ESCC. The clinical potential of TRAP1 was investigated through immunohistochemical analysis in 328 ESCC samples, which revealed that strong TRAP1 expression was associated with increased risk of lymph node metastasis, while high TRAP1 expression correlated with poor prognosis. Expression of TRAP1 was found to be an independent prognostic factor for patients with ESCC. Additionally, the upregulation of TRAP1 antagonized cisplatin-induced apoptosis while its downregulation sensitized cells to cisplatin-induced apoptosis. As revealed by the transwell assay, TRAP1 overexpression promoted cellular migration and invasion as compared to the control groups. In contrast,silencing of endogenous TRAP1 expression attenuated the ability of migration and invasion. Finally, the molecular mechanism investigated in the present study demonstrated that TRAP1-mediated migration and invasion occurred through STAT3/MMP2 signaling pathway. In conclusion, TRAP1 may be considered as a molecular predictive marker for prognosis and a novel molecular candidate for therapeutic target in ESCC.Yunwei Ou Lingyan Liu Liyan Xue Wei Zhou Zitong Zhao Bainan Xu Yongmei Song Qimin Zhan 2014Journal of Genetics and Genomics2014,41,10:8

6Characterization of a Novel Anti-DR5 Monoclonal Antibody WD1 with the Potential to Induce Tumor Cell Apoptosis显示文摘TNF-related apoptosis-inducing ligand (TRAIL) is a TNF family member capable of inducing apoptosis. Death receptor 5 (DR 5) is a key receptor of TRAIL and plays an important role in TRAIL-induced apoptosis. To prepare monoclonal antibodies (mAbs) against DR5,cDNA encoding soluble DR5 (sDR5) was firstly amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) with specific primers,and then inserted into a prokaryotic expression vector pET-30a. The recombinant plasmid was expressed in Escherichia coli strain BL21 (DE3),and sDR5 was purified by nickel affinity chromatography. As an antigen,sDR5 was used to immunize mice. Hybridomas secreting antibodies against sDR5 were identified. One positive clone was selected to produce antibody,WD1. ELISA and immunofluorescence demonstrated that WD1 could bind recombinant sDR5 and membrane-bound DR5 (mDR5) on Jurkat and Molt-4 cells. ATPLite assays showed that Jurkat and Molt-4 cells were sensitive to the antibody in a dose dependent manner. The Annexin V/PI assays and Giemsa's staining both showed that WD1 could induce Jurkat cell apoptosis efficiently. Transient transfection of 293T cells and indirect immunofluorescence assay demonstrated that mAb (WD1) couldn't cross-react with DR4. Our findings indicated that the novel antibody,WD1 could act as a direct agonist,bind DR5 characteristically,and initiate efficient apoptotic signaling and tumor regression. Thus,WD1 would be a leading candidate for potential cancer therapeutics.Jing Wang Zhou Lin Chunxia Qiao Ming Lv Ming Yu He Xiao Qingyang Wang Liyan Wang Jiannan Feng Beifen Shen Yuanfang Ma Yan Li 2008Cellular & Molecular Immunology2008,5,1:4

8A study of peroxyacetyl nitrate at a rural site in Beijing based on continuous observations from 2015 to 2019 and the WRFChem model显示文摘Peroxyacetyl nitrate(PA N)is one of the most important photochemical pollutants and has aroused much concern in China in recent decades.However,few studies described the long-term variations in PAN in China.In this study,we continuously monitored the PAN,03 and NOx concentrations at a regional background site near Beijing from August 2015 to February 2019.Based on the observed concentrations and climate data,w e analyzed the seasonal PAN variations.The results revealed that the monthly mean PAN concentration ranged from 0.33-2.41 ppb,with an average value of 0.94 ppb.The PAN concentration exhibited a distinct seasonal variation,with high values in spring and low values in winter.After analyzing the corresponding meteorological data,we found that stronger ultraviolet(UV)radiation,a relatively longer lifetime and a higher background PAN concentration contributed to the high PAN concentrations in spring.In addition,with the utilization of the WRF-Chem(Weather Research and Forecasting with Chemistry)model,the cause of the extremely high PAN concentration in spring 2018 wa s determined.The model results demonstrated that an anomalously low pressure and the southwesterly winds in northern China might be the main causes of the increased PAN concentration in Beijing and its surrounding area in spring 2018.Yulu Qiu Zhiqiang Ma Weili Lin Weijun Quan Weiwei Pu Yingruo Li Liyan Zhou Qingfeng Shi 2020Frontiers of Environmental Science & Engineering2020,14,4:3
9Constructing G^2 Continuous Curve on Freeform Surface with Normal Projection显示文摘This article presents a new method for G~2 continuous interpolation of an arbitrary sequence of points on an implicit or parametric surface with prescribed tangent direction and curvature vector,respectively,at every point.First,a G~2 continuous curve is constructed in three-dimensional space.Then the curve is projected normally onto the given surface.The desired interpolation curve is just the projection curve,which can be obtained by numerically solving the initialvalue problems for a system of first-order ordinary differential equations in the parametric domain for parametric case or in three-dimensional space for implicit case.Several shape parameters are introduced into the resulting curve,which can be used in subsequent interactive modification so that the shape of the resulting curve meets our demand.The presented method is independent of the geometry and parameterization of the base surface.Numerical experiments demonstrate that it is effective and potentially useful in numerical control (NC) machining,path planning for robotic fibre placement,patterns design on surface and other industrial and research fields.Wang Xiaoping,An Luling,Zhou Laishui,Zhang Liyan Jiangsu Key Laboratory of Precision and Macro-manufacturing Technology,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,China 2010Chinese Journal of Aeronautics2010,23,1:3
10Design and demonstration of a dynamic wireless power transfer system for electric vehicles显示文摘The usage of electric vehicles is being globally promoted with the development of clean energy. However, the development of electric vehicles is limited by the battery capacity and the charging techtechnology.Traditional charging facilities mainly involve plugging invehicles in an electrical interface,which is inconvenient and inherently hazardous.When compared with the traditional charging methods,the wireless charging method can solve several problems,such as the interface limitation,and will be gradually developed as the main charging mode for elec trie vehicles[1].Based on the driving stales of electric vehicles,the wireless charging technologies can be mainly classified as static wireless charging and dynamic wireless charging.Ze ZHOU Liyan ZHANG Zhitao LIU Longhua MA Miao HUANG Hongye SU 2019Science China(Information Sciences)2019,62,12:2

17Identification and characterization of loop7 motif and its role in regulating biological function of human APOBEC3G through molecular modeling and biological assay显示文摘Human APOBEC3G(h A3G) is a cytidine deaminase which inhibits HIV-1 replication. The HIV-1 accessory protein viral infectivity factor(Vif) counteracts with hA3G by targeting it for proteasomal degradation. In this work, we constructed and optimized molecular models of the hA3G dimer and the h A3G–Vif complex. The molecular modeling study revealed that the loop7 motif of hA3G appears on the interfaces of both the h A3G–Vif complex and the hA3G dimer. Biochemical analysis provided evidence suggesting that binding of Vif to hA3G results in steric blocking of hA3G dimerization, implying that monomeric hA3G serves as a substrate for Vif-mediated degradation.Furthermore, we presented evidence for the important roles of the loop7 motif, especially the central residues within the region, in hA3G dimerization, h A3G–Vif interaction, Vif-mediated hA3G degradation as well as subcellular localization of hA3G. This work highlights a multiple-task interface formed by loop7 motif, which regulates biological function of hA3G, thus providing the feasibility of the strategy of blocking Vif-mediated A3 G degradation by targeting the putative site around loop7.Congjie Zhai Ling Ma Zhixin Zhang Jiwei Ding Jing Wang Yongxin Zhang Xiaoyu Li Fei Guo Liyan Yu Jinming Zhou Shan Cen 2017Acta Pharmaceutica Sinica B2017,7,5:1
18Multi-platform omics analysis reveals molecular signature for COVID-19 pathogenesis,prognosis and drug target discovery显示文摘Disease progression prediction and therapeutic drug target discovery for Coronavirus disease 2019(COVID-19)are particularly important,as there is still no effective strategy for severe COVID-19 patient treatment.Herein,we performed multi-platform omics analysis of serial plasma and urine samples collected from patients during the course of COVID-19.Integrative analyses of these omics data revealed several potential therapeutic targets,such as ANXA1 and CLEC3B.Molecular changes in plasma indicated dysregulation of macrophage and suppression of T cell functions in severe patients compared to those in non-severe patients.Further,we chose 25 important molecular signatures as potential biomarkers for the prediction of disease severity.The prediction power was validated using corresponding urine samples and plasma samples from new COVID-19 patient cohort,with AUC reached to 0.904 and 0.988,respectively.In conclusion,our omics data proposed not only potential therapeutic targets,but also biomarkers for understanding the pathogenesis of severe COVID-19.Yuming Li Guixue Hou Haibo Zhou Yanqun Wang Hein Min Tun Airu Zhu Jingxian Zhao Fei Xiao Shanwen Lin Dongdong Liu Dunrong Zhou Lang Mai Lu Zhang Zhaoyong Zhang Lijun Kuang Jiao Guan Qiushi Chen Liyan Wen Yanjun Zhang Jianfen Zhuo Fang Li Zhen Zhuang Zhao Chen Ling Luo Donglan Liu Chunke Chen Mian Gan Nanshan Zhong Jincun Zhao Yan Ren Yonghao Xu 2021Signal Transduction and Targeted Therapy2021,6,5:1
