3Combination types between graphene oxide and substrate affect the antibacterial activity显示文摘Duo to their superior physicochemical properties,graphene and its derivatives(GDs),such as graphene oxide(GO)and reduced graphene oxide(rGO),have attracted extensive research interests around the world.In recent years,antibacterial activities of GDs have aroused wide concern and substantial works have been done.However,the underlying antibacterial mechanisms still remain controversial.Antibacterial activities of GDs vary with various factors,such as size,number of layers,oxygen-containing groups,and experimental surroundings.We assume that combination types between graphene oxide and substrate may affect the antibacterial activity.Therefore,in this work,GO was fixed on the titanium surface with three kinds of combination types including drop with gravitational effects(GO-D),electrostatic interaction(GO-APS)and electrophoretic deposition(GO-EPD),and the antibacterial activities in vitro were systematically investigated.Results showed that combination types affected the ability of GO for preventing Staphylococcus aureus(S.aureus)from gathering,sharpness of wrinkles or edges and reactive oxygen spices(ROS)levels.Once S.aureus are in the form of separation without aggregation,GO can effectively interact with them and kill them with sharp wrinkles or edges and high ROS levels.GOEPD could effectively prevent S.aureus from gathering,own sharp wrinkles or edges and could generate higher ROS levels.As a result,GO-EPD exhibited optimal antibacterial activity against S.aureus,followed by GO-APS and GO-D.Jiajun Qiu Lu Liu Hongqin Zhu Xuanyong Liu 2018Bioactive Materials2018,3,3:7
4Indications of stratospheric anomalies in the freezing rain and snow disaster in South China,2008显示文摘NCEP/NCAR reanalysis data were used to characterize stratospheric temperature and water-vapor anomalies before and after the freezing rain and snow disaster of South China in 2008,and the influence of stratospheric circulation anomalies on the troposphere.Stratospheric temperature and water-vapor anomalies provided good leading indicators of this weather event.The period from December 1st 2007 to February 28th 2008 was divided into 18 pentads.During the 6th pentad,temperature decreased significantly at 10 hPa in the near-polar stratospheric region,and the decreasing trend strengthened and extended downward and southward to middle and lower latitudes.During the 14th-18th pentads,the temperature decrease reached its maximum and extended to 30°N.This coincided with the widespread freezing rain and snow event.By the end of January 2008,the temperature decrease ended in the near-polar stratospheric region,but continued in the mid-latitude area of the troposphere as the freezing rain and snow weather persisted.Similar to the temperature variations,positive anomalies of relative humidity in the stratospheric near-polar region also strengthened and extended downward and southward,coinciding with the freezing rain and snow event.Along with the significant relationship between the freezing rain and snow disaster and stratospheric circulation anomalies,the stratospheric polar vortex changed its shape in late December,intensifying and spreading downward from the top of the stratosphere and southward to the Asian continent,resulting in a deepening of the East Asian Trough and a strengthening of meridional circulation.Before the occurrence of the freezing rain and snow event,temperature and vapor increases in the stratosphere transferred downward to the troposphere,along with a stratospheric flow in the near-polar region southward to lower latitudes.CHEN QuanLiang LI Zhan FAN GuangZhou ZHU KeYun ZHANG Wen ZHU HongQin 2011Science China Earth Sciences2011,54,8:5
5Preliminary Investigation on the Main Fungal Diseases of Sugarcane in Guangxi Province of China显示文摘[Objective] The purpose was to understand species and occurrence status of major fugal diseases in sugarcane cultivation areas of Guangxi in China, so as to provide scientific references for integrated control against sugarcane diseases. [Method] Species and occurrence degrees of major fugal diseases in sugarcane cultivation areas of Guangxi were investigated through randomized surveys, farmer interviews, literature references and location investigations from 2009 to 2011. Diseased sugarcane samples were collected and their species were identified through pathogen isolated culture and other relevant methods. [Result] Thirteen species of fungal diseases were identified in the survey, including pineapple disease [Thielaviopsis paradoxa (de Seynes) V. Hohnel], smut(Ustilago scitaminea Sydow), top rot disease (Fusarium moniliforme Sheldon), rust (Puccinia melanocephala H.﹠P. Syd.), leaf scald disease (Stagonospora sacchari Lo et Ling), red rot disease (Colletotrichum falcatum Went), zonate spot disease (Phyllosticta saccharicola P. Henn.), leaf red spot disease [Pellicularia sasakii (Shirai) Ito], white rash disease (Elsinoe sacchari L.), eye spot [Helminthosporium sacchari (Breda de Haan) Butler], yellow spot [Mycovellosiella koepkei (kruger) Deighton], brown stripe [Bipolaris stenospilum (Drechs.) Shoem.]and brown spot (Cercospora longipes Butler). Smut, rust, top rot, and pineapple disease were the most rampantly detrimental to quality and yield of sugarcane. [Conclusion] Smut is the most serious sugarcane disease; it is urgent to breed sugarcane varieties with high resistance and excellent agronomic characters to replace current sugarcane varieties susceptible to diseases.Wei Jinju Deng Zhanyun Huang Chenghua Huang Weihua Yan Meixin Liu Haibin Tang Hongqin 2013Plant Diseases and Pests2013,4,1:3
6Ni_2P/ZrO_2-SBA-15 Dibenzothiophene Hydrodesulfurization Catalysts: Preparation,Characterization and Evaluation显示文摘Ni_2P/ZrO_2-SBA-15 catalysts with different zirconium n-propoxide/SBA-15 mass ratios were synthesized to evaluate their dibenzothiophene hydrodesulfurization catalytic activity. Effect of ZrO_2 introduction was investigated. Supports and catalysts were characterized by BET,XRD,^(29)SiNMR,XPS and FTIR. The results indicated that zirconium was incorporated into SBA-15 in the forms of [(–O–)_2 Si(–O–Zr)_2 ] and/or [(–O–)_3 Si–O–Zr],and that the SBA-15 framework structure was maintained after incorporation of ZrO_2. With zirconium content increasing,ZrO_2 was transformed from amorphous phase to tetragonal phase. Zirconium incorporation into SBA-15 supports could facilitate to form more dispersed Ni_2P active phase. There might be some interaction occurring between the P and Zr species. In addition to Ni_2P,another kind of active phase,ZrP,was formed,which might exhibit a better HDS activity than Ni_2P. It was observed that at a temperature of 280 °C,pressure of 3.0 MPa,WHSV of 6.5 h^(-1) and H_2 to oil ratio of 450,the Ni_2P/Zr-SBA(1.5) catalyst,where 1.5 represents zirconium n-propoxide/SBA-15 mass ratio,showed the highest DBT conversion,which was 86.6%,almost 35% higher than that of the Ni_2P/Zr-SBA(0) catalyst.Hongqin Ma Qiurong Li Yang Shi Xiao Sun 2018Transactions of Tianjin University2018,24,4:3

10Culturing adequate CAR-T cells from less peripheral blood to treat B-cell malignancies显示文摘Objective:Chimeric antigen receptor-modified T(CAR-T)cells have shown impressive results against relapsed/refractory B cell malignancies.However,the traditional manufacture of CAR-T cells requires leukapheresis to isolate large amounts of peripheral blood T cells,thus making some patients ineligible for the procedure.Methods:We developed a simple method for CAR-T cell preparation requiring small volumes of peripheral blood.First,CD3+T cells isolated from 50 mL peripheral blood from patients(B-cell malignancies)were stimulated with immobilized anti-CD3/RetroNectin in 6-well plates and then transduced with CAR-expressing lentiviral vector.After 4 d,the T cells were transferred to culture bags for large-scale CAR-T cell expansion.In vitro and animal experiments were performed to evaluate the activity of the manufactured CAR-T cells.Finally,29 patients with B-cell acute lymphoblastic leukemia(B-ALL)and 9 patients with B-cell lymphoma were treated with the CAR-T cells.Results:The CAR-T cells were expanded to 1–3×10^(8) cells in 8–10 d and successfully killed B cell-derived malignant tumor cells in vitro and in vivo.For patients with B-ALL,the complete remission rate was 93%1 month after CAR-T cell infusion;after 12 months,the overall survival(OS)and leukemia-free survival rates were 69%and 31%,respectively.For patients with lymphoma,the objective response rate(including complete and partial remission)was 78%2 months after CAR-T cell infusion,and after 12 months,the OS and progression-free survival rates were 71%and 43%,respectively.Cytokine-release syndrome(CRS)occurred in 65.51%and 55.56%of patients with B-ALL and B-cell lymphoma,respectively;severe CRS developed in 20.69%of patients with B-ALL and in no patients with lymphoma.Conclusions:Our novel method can generate sufficient numbers of CAR-T cells for clinical use from 50–100 mL peripheral blood,thus providing an alternative means of CAR-T cell generation for patients ineligible for leukapheresis.Lu Han Jian Zhou Linlin Li Keshu Zhou Lingdi Zhao Xinghu Zhu Qingsong Yin Yufu Li Hongqin You Jishuai Zhang Yongping Song Quanli Gao 2021Cancer Biology & Medicine2021,18,4:2

12Impacts of Multigrid NLS-4DVar-based Doppler Radar Observation Assimilation on Numerical Simulations of Landfalling Typhoon Haikui (2012)显示文摘We applied the multigrid nonlinear least-squares four-dimensional variational assimilation(MG-NLS4DVar)method in data assimilation and prediction experiments for Typhoon Haikui(2012)using the Weather Research and Forecasting(WRF)model.Observation data included radial velocity(Vr)and reflectivity(Z)data from a single Doppler radar,quality controlled prior to assimilation.Typhoon prediction results were evaluated and compared between the NLS-4DVar and MG-NLS4DVar methods.Compared with a forecast that began with NCEP analysis data,our radar data assimilation results were clearly improved in terms of structure,intensity,track,and precipitation prediction for Typhoon Haikui(2012).The results showed that the assimilation accuracy of the NLS-4DVar method was similar to that of the MG-NLS4DVar method,but that the latter was more efficient.The assimilation of Vr alone and Z alone each improved predictions of typhoon intensity,track,and precipitation;however,the impacts of Vr data were significantly greater that those of Z data.Assimilation window-length sensitivity experiments showed that a 6-h assimilation window with 30-min assimilation intervals produced slightly better results than either a 3-h assimilation window with 15-min assimilation intervals or a 1-h assimilation window with 6-min assimilation intervals.Lu ZHANG Xiangjun TIAN Hongqin ZHANG Feng CHEN 2020Advances in Atmospheric Sciences2020,37,8:1
