| 1 | Leaching ion adsorption rare earth by aluminum sulfate for increasing efficiency and lowering the environmental impact显示文摘The leaching efficiency(LE) of ion adsorption rare earth(IARE) by the sulfate and chloride of ammonium,magnesium and aluminum were comparatively determined using column leaching method. It is found that at equal equivalent concentration of cation, the LE of IARE by aluminum sulfate is the highest, and the zeta potential of clay mineral particles in the tailing is near to zero, which means a lower risk of landslide and pollutant emission. Furthermore, the optimum concentration of aluminum sulfate is determined to be0.02 mol/L, which is much lower than that of ammonium sulfate and magnesium sulfate. To reduce the production cost and environmental impact, we proposed a multi-stage leaching process, which was firstly leaching with ammonium sulfate and then with aluminum sulfate, following by water washing and lime neutralizing. With the ratio of ammonium sulfate to aluminum sulfate varying from 1:0 to 0.5:0.5, the residual ammonium in tailing decreases from 11.2% to 0.6%, however, the LE of RE shows an optimum value at 0.8:0.2. By neutralizing the pH of tailing with lime water to over 6, the ion concentration in water rinsing solution can meet the requirement for water discharge. At the same time, the zeta potential of clay particles is found to be around-5 mV, means a relatively lower risk of landslide. These facts indicate that the LE of IARE can be increased and the danger caused by tailings landslides and pollutant emissions can be reduced by replacing ammonium sulfate with aluminum sulfate as leaching reagent. | Lifen Yang Cuicui Li Dashan Wang Fengyang Li Yanzhu Liu Xuezhen Zhou Mingbiao Liu Xiufeng Wang Yongxiu Li | 2019 | Journal of Rare Earths2019，37，4： | 19 |
| 2 | Effects of COD/N ratio and DO concentration on simultaneous nitrification and denitrification in an airlift internal circulation membrane bioreactor显示文摘The effects of chemical oxygen demand and nitrogen(COD/N)ratio and dissolved oxygen concentration(DO)on simultaneous nitrification and denitrification(SND)were investigated using an airlift internal circulation membrane bioreactor(AIC-MBR)with synthetic wastewater.The results showed that the COD efficiencies were consistently greater than 90% regardless of changes in the COD/N ratio.At the COD/N ratio of 4.77 and 10.04,the system nitrogen removal efficiency became higher than 70%.However,the nitrogen rem... | Meng Qingjuan Yang Fenglin Liu Lifen Meng Fangang | 2008 | Journal of Environmental Sciences2008，20，8： | 18 |
| 3 | Relationships Between Yield, Quality and Nitrogen Uptake and Utilization of Organically Grown Rice Varieties显示文摘Due to the relatively late start of organic rice(Oryza sativa L.) research in China,there is a still lack of systematic research on rice varieties,organic fertilizer management practices,and especially the mechanisms of nitrogen(N) uptake and utilization.Three rice varieties,Nanjing 5055,Nanjing 9108,and Nanjing 46,were grown under organic farming(OF) at three organic fertilizer levels(103.2,160.8,and 218.4 kg N ha^(-1)) and conventional farming(CF) with regular chemical fertilizers.Rice grain yields,yield components,and quality,dry matter accumulation,and plant N were measured at different growth stages during the 2012 and 2013 growing seasons.Compared with CF,OF had a significantly reduced yield.Nanjing 9108 showed significant reductions in number of panicles per unit area and percentage of filled grains,and had the lowest yield.The effects of fertilizer type and application rate on dry matter accumulation during the main growth periods were significant for all varieties.The N content and uptake in organically grown rice were lower compared with those of rice under CF.The N recovery efficiency and N agronomic efficiency were significantly lower,whereas N physiological efficiency and N partial factor productivity were greater under OF than under CF.Under OF,the processing quality showed a slight but insignificant decline,protein content and gel consistency increased,and amylose content decreased compared with those under CF.Correlation analysis showed that under OF,grain yield was significantly correlated with N uptake.The medium organic fertilizer level(160.8 kg N ha^(-1)) was found to be the optimum fertilizer treatment,and Nanjing 46 appeared to be the best variety for organic rice cultivation.To increase rice grain yields and reduce the potential risk of non-point source pollution in organic agriculture,further research is needed to improve the N use efficiency in organic rice cultivation. | HUANG Lifen YU Jun YANG Jie ZHANG Rong BAI Yanchao SUN Chengming ZHUANG Hengyang | 2016 | Pedosphere2016，26，1： | 11 |

| 7 | Hepatitis B virus evades immune recognition via RNA adenosine deaminase ADAR1-mediated viral RNA editing in hepatocytes显示文摘HBV is considered as a“stealth”virus that does not invoke interferon(IFN)responses;however,the mechanisms by which HBV bypasses innate immune recognition are poorly understood.In this study,we identified adenosine deaminases acting on RNA 1(ADAR1),which is a key factor in HBV evasion from IFN responses in hepatocytes.Mechanically,ADAR1 interacted with HBV RNAs and deaminated adenosine(A)to generate inosine(I),which disrupted host immune recognition and thus promoted HBV replication.Loss of ADAR1 or its deficient deaminase activity promoted IFN responses and inhibited HBV replication in hepatocytes,and blocking the IFN signaling pathways released the inhibition of HBV replication caused by ADAR1 deficiency.Notably,the HBV X protein(HBx)transcriptionally promoted ADAR1 expression to increase the threshold required to trigger intrinsic immune activation,which in turn enhanced HBV escape from immune recognition,leading to persistent infection.Supplementation with 8-azaadenosine,an ADAR1 inhibitor,efficiently enhanced liver immune activation to promote HBV clearance in vivo and in vitro.Taken together,our results delineate a molecular mechanism by which HBx promotes ADAR1-derived HBV immune escape and suggest a targeted therapeutic intervention for HBV infection. | Liyuan Wang Yang Sun Xiaojia Song Zehua Wang Yankun Zhang Ying Zhao Xueqi Peng Xiaodong Zhang Chunyang Li Chengjiang Gao Nailin Li Lifen Gao Xiaohong Liang Zhuanchang Wu Chunhong Ma | 2021 | Cellular & Molecular Immunology2021，18，8： | 2 |
| 8 | Thermal evolution effects on the properties of converting Cs-polluted soil into pollucite-base glass-ceramics for radioactive cesium immobilization显示文摘The Fukushima nuclear accident in Japan on March 11,2011,produced large amounts of Cs-polluted soil which must be controlled to prevent the spread of hazardous Cs into the environment.In this paper,the effects of heat treatment on the structure and properties of Cs-containing glass-ceramics,as a simulated nuclear waste form,were systematically investigated.Cesium atoms are chemically bonded in the pollucite structure,and the amorphous phase further encapsulates the pollucite crystals in the glassceramics,thus providing an extra protective layer for the immobilized Cs.XRD analysis,Raman and FT-IR studies on the glass-ceramics synergistically indicated that the optimum crystallization temperature for pollucite is around 1000℃.The pollucite is predominantly the main crystalline phase with a narrow crystal size distribution between 0.5 and 2 mm.Standard leaching test results show that the leaching rate of Cs was very low(3.0×10^(-3) g/(m^(2)·d)).The study offers a practical method for immobilizing Cs in pollucite-base glass-ceramics.Moreover,the experimentally obtained data may provide some important references for converting Cs-polluted soil into pollucite-base glass-ceramics waste form. | Yong Yang Xin Cao Lifen Shi Zhengyi Zhang Pingping Wang Jinwei Li Yangshan Sun Shuyong Chen Tianhe Wang Liyun Ma Shou Peng | 2021 | Journal of Materiomics2021，7，6： | 2 |

| 10 | CUL4B facilitates HBV replication by promoting HBx stabilization显示文摘Objective:Hepatitis B virus(HBV)infection is a major public health problem worldwide.However,the regulatory mechanisms underlying HBV replication remain unclear.Cullin 4 B-RING ubiquitin E3 ligase(CRL4 B)is involved in regulating diverse physiological and pathophysiological processes.In our study,we aimed to explain the role of CUL4 B in HBV infection.Methods:Cul4 b transgenic mice or conditional knockout mice,as well as liver cell lines with CUL4 B overexpression or knockdown,were used to assess the role of CUL4 B in HBV replication.Immunoprecipitation assays and immunofluorescence staining were performed to study the interaction between CUL4 B and HBx.Cycloheximide chase assays and in vivo ubiquitination assays were performed to evaluate the half-life and the ubiquitination status of HBx.Results:The hydrodynamics-based hepatitis B model in Cul4 b transgenic or conditional knockout mice indicated that CUL4 B promoted HBV replication(P<0.05).Moreover,the overexpression or knockdown system in human liver cell lines validated that CUL4 B increased HBV replication in an HBx-dependent manner.Importantly,immunoprecipitation assays and immunofluorescence staining showed an interaction between CUL4 B and HBx.Furthermore,CUL4 B upregulated HBx protein levels by inhibiting HBx ubiquitination and proteasomal degradation(P<0.05).Finally,a positive correlation between CUL4 B expression and HBV pg RNA level was observed in liver tissues from HBV-positive patients and HBV transgenic mice.Conclusions:CUL4 B enhances HBV replication by interacting with HBx and disrupting its ubiquitin-dependent proteasomal degradation.CUL4 B may therefore be a potential target for anti-HBV therapy. | Haixia Shan Bo Wang Xiaodong Zhang Hui Song Xi Li Yongxin Zou Baichun Jiang Huili Hu Hao Dou Changshun Shao Lifen Gao Chunhong Ma Xiaoyun Yang Xiaohong Liang Yaoqin Gong | 2022 | Cancer Biology & Medicine2022，19，1： | 2 |

| 19 | Longitudinal residual circulation in the South Passage of Yangtze Estuary:Combined influences from runoff,tide and bathymetry显示文摘Classical estuary circulation theory states that in the longitudinal direction of an estuary there exists a single circulation with landward,near-bottom,and seaward,near-surface flows;however,the situation becomes complicated with the presence of a river mouth bar.Here we conducted tidal-cycle observations in the South Passage of the Yangtze Estuary during both the wet and dry seasons of 2018(July and December,respectively).The simultaneous current velocity,temperature,and salinity profile data were obtained from anchored boats and base tripods at three stations along the channel in the mouth bar area.The results reveal two distinct longitudinal residual circulation patterns:a classic circulation which is formed on the seaward slope of the mouth bar during the wet season,and a double circulation system which is composed of two circulation cells over the landward and seaward slopes of the mouth bar during the dry season.The Simpson number(Si),mixing parameter(M),and salinity data were used to quantify the mixing intensity,which shows that horizontal baroclinic pressure gradient is the dominant factor in the formation of the longitudinal residual circulation.Furthermore,the double circulation pattern during the dry season is related to the mouth bar bathymetry,which affects saltwater intrusion.The double circulations can significantly influence the spatial and temporal evolution of the stagnation point in the estuarine channel,which in turn modifies the distribution patterns of suspended sediment concentration in the maximum turbidity zone.Evidently,the changes in the mouth bar sandbar bathymetry in response to human activities and river basin hydrographic conditions indirectly affect the occurrence and scale of the double circulations. | Lifen ZHANG Zuosheng YANG Fan ZHANG Zhanhai LI Yaping WANG Shu GAO | 2021 | Science China Earth Sciences2021，64，12： | 1 |
