4Performance and microbial community of a membrane bioreactor system--Treating wastewater from ethanol fermentation of food waste显示文摘In this study, a lab-scale biological anaerobic/anaerobic/anoxic/membrane bioreactor(A_-~3MBR) was designed to treat wastewater from the ethanol fermentation of food waste,a promising way for the disposal of food waste and reclamation of resources. The 454 pyrosequencing technique was used to investigate the composition of the microbial community in the treatment system. The system yielded a stable effluent concentration of chemical oxygen demand(202 ± 23 mg/L), total nitrogen(62.1 ± 7.1 mg/L), ammonia(0.3 ±0.13 mg/L) and total phosphorus(8.3 ± 0.9 mg/L), and the reactors played different roles in specific pollutant removal. The exploration of the microbial community in the system revealed that:(1) the microbial diversity of anaerobic reactors A_1 and A_2, in which organic pollutants were massively degraded, was much higher than that in anoxic A_3 and aerobic MBR;(2) although the community composition in each reactor was quite different, bacteria assigned to the classes Clostridia, Bacteroidia, and Synergistia were important and common microorganisms for organic pollutant degradation in the anaerobic units, and bacteria from Alphaproteobacteria and Betaproteobacteria were the dominant microbial population in A_3 and MBR;(3) the taxon identification indicated that Arcobacter in the anaerobic reactors and Thauera in the anoxic reactor were two representative genera in the biological process. Our results proved that the biological A_-~3MBR process is an alternative technique for treating wastewater from food waste.Xiaobiao Zhu Mengqi Li Wei Zheng Rui Liu Lujun Chen 2017Journal of Environmental Sciences2017,29,3:4
5Value of low-dose and optimized-length computed tomography(CT)scan in CT-guided percutaneous transthoracic needle biopsy of pulmonary nodules显示文摘Objective:To investigate the value of application of low-dose and optimized length CT scan on puncture results,complications and patients’radiation dosage during CT-guided percutaneous biopsy of pulmonary nodules(PTNB).Methods:A total of 231 patients with PTNB under CT guidance were collected.Low dose scanning utilized tube current of 20 mA as compared with 40 mA in conventional dosage.Optimized length in CT is defined as intentionally narrowing the range of CT scanning just to cover 25 mm(5 layers)around the target layer during needle adjustment.According to whether low-dose scans and optimized length scans techniques were utilized,patients were divided into three groups:conventional group(conventional sequence+no optimization),optimized length group(conventional sequence+optimized length),and low-dose optimized length group(low dose sequence+optimized length).The ED(effective dose),the DLP(dose length product),the average CTDIvol(Volume CT dose index),total milliampere second between subgroups were compared.Results:Compared with the conventional group,ED,intraoperative guidance DLP,total milliseconds and operation time in the optimized length group were reduced by 18.2%(P=0.01),37%(P=0.003),17.5%(P=0.013)and13.3%(P=0.021)respectively.Compared with the optimized length group,the ED was reduced by 87%,preoperative positioning,intraoperative guidance and postoperative review DLP were also reduced by 88%,total milliampere second was reduced by 79%,with an average CTDIvol was reduced by 86%,in the low-dose optimized length group(P<0.001 for all).Conclusion:Optimizing the length during CT scanning can effectively reduce the intraoperative radiation dose and reduce the operation time compared with conventional plan;low-dose and optimized length CT scan can further reduce the total radiation dose compared with optimized length group with no differences on intraoperative complications,biopsy results and operation time.Hui Yuan Da Li Yan Zhang Xiaozhen Xie Lujun Shen 2021Journal of Interventional Medicine2021,4,3:4
6Constitutive equation and hot deformation characteristic of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy with equiaxed microstructure显示文摘The hot deformation behavior of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy with equiaxed microstructure was characterized in the temperature range of 900~1060 ℃ and strain rate range of 10-3~10 s-1.The experimental results indicate that the plastic deformation behavior of the titanium alloys is rather sensitive to temperature and strain rate.In the α+β phase temperature region,all of the stress-strain curves exhibit different degrees of the flow softening after a peak stress.In the β phase temperature region,the titanium alloy shows a stress softening at high strain rates and a steady flow stress at low strain rates.On the basis of the peak stress data,the constitutive equations were constructed in the α+β phase temperature region and β phase temperature region,respectively.Activation energy parameters were calculated to be 344.923 kJ·mol-1 in the β phase temperature region and 628.3 kJ·mol-1 in the α+β phase temperature region.Microstructure of the compressed specimens in water-quenched conditions was found to be quite dependent on the conditions of deformation.HUANG Lujun,GENG Lin,LI Aibin,WANG Guisong,and SHI Lei School of Materials Science and Engineering,Harbin Institute of Technology,Harbin 150001,China 2007Rare Metals2007,26,S1:3

10EGFR tyrosine kinase inhibitor HS-10182 increases radiation sensitivity in non-small cell lung cancers with EGFR T790M mutation显示文摘Objective:To investigate the potential of HS-10182,a second-generation epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI),as a radiosensitizer in non-small cell lung cancer(NSCLC).Methods:Two cell lines of NSCLCs,A549 that possesses wild-type(WT)EGFRs and H1975 that possesses EGFR L858R/T790M double mutations,were treated with HS-10182 at various concentrations,and cell viabilities were determined using the MTS assay.The cells were tested by clonogenic survival assays to identify the radiosensitivity of both groups.Western blot was performed to analyze the expression of phosphorylated EGFR,AKT,DNA-dependent protein kinase,and catalytic subunit(DNA-PKcs)proteins.Immunofluorescence analyses were performed to examine the formation and changes in nuclearγ-H2AX foci.Cell apoptosis was examined by flow cytometry and Western blots for cleaved caspase-3,-8,-9,and cleaved poly ADP-ribose polymerase(PARP).Furthermore,we established xenograft models in mice and the effects of different treatments on tumor growth were then assessed.Results:Clonogenic survival assays revealed that HS-10182 significantly enhanced the radiosensitivity of H1975 cells but not A549cells[dose enhancement ratios(DERs)=2.36(P<0.05)vs.1.43(P>0.05)].Western blot results showed that HS-10182 increased the levels of cleaved caspase-3,-8,-9,and cleaved PARP in H1975 cells but not in A549 cells.In addition,flow cytometry analysis showed that HS-10182 enhanced irradiation-induced apoptosis in H1975.Immunofluorescence results found that HS-10182increased the average number ofγ-H2AX foci after irradiation in H1975 cells,but not in A549 cells.Combined radiation and HS-10182 treatment increased the expression of DNA-PKcs but this increase was more significant in H1975 cells than in A549 cells.Moreover,HS-10182 suppressed the increased expression of Rad50 in H1975 cells in response to irradiation.In vivo experiments found that the combined therapy significantly inhibited tumor growth.Conclusions:HS-10182 enhances the radiosensitivity of H1975 cells which is possibly because that HS-10182 could enhance irradiation-induced apoptosis,increase irradiation-induced DNA damage,and cause a delay in DNA damage repair.Our findings suggest that radiotherapy combined HS-10182 is a novel treatment for lung cancer cells which have acquired the T790M mutation.HS-10182 could be brought to the clinic as a radiosensitizer in NSCLCs with the EGFR T790M mutation.Yang Chen Youyou Wang Lujun Zhao Ping Wang Jifeng Sun Rudi Bao Chenghai Li Ningbo Liu 2018Cancer Biology & Medicine2018,15,1:2
11Isobaric vapor–liquid equilibrium for ternary system of ethanol, ethyl propionate and para-xylene at 101.3 kPa显示文摘Isobaric vapor–liquid equilibrium(VLE) data for the binary system ethyl propionate(2) + para-xylene(3) and ternary system ethanol(1) + ethyl propionate(2) + para-xylene(2) at atmospheric pressure(101.3 k Pa)were obtained by a VLE modified othmer still. All the experimental data passed a point to point consistency test of Van Ness method, which verified the data reliability. The Wilson and UNIQUAC activity coefficient models were employed to correlate the binary VLE data to obtain binary interaction parameters. Based on binary interaction parameters, ternary VLE data of ethanol(1) + ethyl propionate(2) + para-xylene(3) were predicted by Wilson and UNIQUAC models, which proved that predicted values are consistent with the experimental data.Furthermore, azeotropic phenomenon between ethanol and ethyl propionate disappears when the mole ratio of para-xylene and binary system of ethanol and ethyl propionate is 1:1. Therefore, this paper convinced that para-xylene is a proper extractive additive that could be used in extractive distillation to separate the binary azeotropic system of ethanol and ethyl propionate.Zhongpeng Xing Yujie Gao Hui Ding Xianqin Wang Lujun Li Hang Zhou 2018Chinese Journal of Chemical Engineering2018,26,3:1

13The mechanism for tuning the corrosion resistance and pore density of plasma electrolytic oxidation(PEO)coatings on Mg alloy with fluoride addition显示文摘Here we prepared PEO coatings on Mg alloys in silicate-NaOH-phosphate electrolyte containing different concentrations of NaF addition.The detailed microstructural characterizations combining with potentiodynamic polarization and electrochemical impedance spectra(EIS)were employed to investigate the roles of fluoride in the growth and corrosion properties of PEO coating on Mg.The result shows the introduction of NaF led to a fluoride-containing nanolayer(FNL)formed at the Mg/coating interface.The FNL consists of MgO nanoparticles and insoluble MgF_(2)nanoparticles(containing rutile phase and cubic phase).The increase in the NaF concentration of the electrolyte increases the thickness and the MgF_(2)content in the FNL.When anodized in the electrolyte containing 2 g/L NaF,the formed FNL has the highest thickness of 100-200 nm along with the highest value of x of∼0.6 in(MgO)_(1-x)(MgF_(2))x resulted in the highest corrosion performance of PEO coating.In addition,when anodized in the electrolyte containing a low NaF concentration(0.4-0.8 g/L),the formed FNL was thin and discontinuous,which would decrease the pore density and increase the coating's uniformness simultaneously.Zhu Lujun Li Hongzhan Ma Qingmei Lu Jiangbo Li Zhengxian 2023Journal of Magnesium and Alloys2023,11,8:1

16Combining quantitative and qualitative magnetic resonance imaging features to differentiate anorectal malignant melanoma from low rectal cancer显示文摘Background:Distinguishing anorectal malignant melanoma from low rectal cancer remains challenging because of the overlap of clinical symptoms and imaging findings.We aim to investigate whether combining quantitative and qualitative magnetic resonance imaging(MRI)features could differentiate anorectal malignant melanoma from low rectal cancer.Methods:Thirty-seven anorectal malignant melanoma and 98 low rectal cancer patients who underwent preoperative rectal MRI from three hospitals were retrospectively enrolled.All patients were divided into the primary cohort(N=84)and validation cohort(N=51).Quantitative image analysiswas performed on T1-weighted(T1WI),T2-weighted(T2WI),and contrast-enhanced T1-weighted imaging(CE-T1WI).The subjective qualitative MRI findings were evaluated by two radiologists in consensus.Multivariable analysis was performed using stepwise logistic regression.The discrimination performance was assessed by the area under the receiver operating characteristic curve(AUC)with a 95%confidence interval(CI).Results:The skewness derived from T2WI(T2WI-skewness)showed the best discrimination performance among the entire quantitative image features for differentiating anorectal malignant melanoma from low rectal cancer(primary cohort:AUC=0.852,95%CI 0.788–0.916;validation cohort:0.730,0.645–0.815).Multivariable analysis indicated that T2WI-skewness and the signal intensity of T1WI were independent factors,and incorporating both factors achieved good discrimination performance in two cohorts(primary cohort:AUC=0.913,95%CI 0.868–0.958;validation cohort:0.902,0.844–0.960).Conclusions:Incorporating T2WI-skewness and the signal intensity of T1WI achieved good performance for differentiating anorectal malignant melanoma from low rectal cancer.The quantitative image analysis helps improve diagnostic accuracy.Zeyan Xu Ke Zhao Lujun Han Pinxiong Li Zhenwei Shi Xiaomei Huang Chu Han Huihui Wang Minglei Chen Chen Liu Yanting Liang Suyun Li Yanqi Huang Xin Chen Changhong Liang Wuteng Cao Zaiyi Liu 2021Precision Clinical Medicine2021,4,2:0
17Selective targeted adsorption and inactivation of antibiotic-resistant bacteria by Cr-loaded mixed metal oxides显示文摘Herein we provide a novel high-efficiency nanocomposite for bacterial capture based on mixed metal oxides(MMOs)with deleterious chromium properties.With both the layer structure of layered double hydroxides(LDHs)and the magnetic properties of Fe,MMOs enrich the location of ionic forms on the surface,providing a good carrier for adsorption of the heavy metal Cr(VI).The capacity for adsorption of Cr(VI)by MMOs can be as high as 98.80 mg/g.The prepared Cr(VI)-MMOs achieved extremely expeditious location of gram-negative antibiotic-resistant E.coliNDM-1 by identifying lipid bilayers.Cr-MMOs with a Cr loading of 19.70 mg/g had the best bactericidal effect,and the concentration of E.coliNDM-1 was decreased from~10^(8) to~10^(3) CFU/mL after 30 min of reaction.The binding of nitrogen and phosphorus hydrophilic groups to chromate generated realistic models for density functional theory(DFT)calculations.The specific selectivity of MMOs toward bacterial cells was improved by taking Cr(VI)as a transferable medium,thereby enhancing the antibacterial activity of Cr-MMOs.Under the combined action of chemical and physical reactions,Cr(VI)-MMOs achieved high capacity for inactivation of bacteria.Moreover,the metallic elements ratio in Cr-MMOs remained stable in their initial valence states after inactivation.This guaranteed high removal efficiency for both heavy metals and bacteria,allowing recycling of the adsorbent in practical applications.Yanlin Li Bo Wang Lei Zhu Yixing Yuan Lujun Chen Jun Ma 2022Frontiers of Environmental Science & Engineering2022,16,6:0
18Multiple plasmon couplings in 3D hybrid Au-nanoparticles-decorated Ag nanocone arrays boosting highly sensitive surface enhanced Raman scattering显示文摘Plasmon coupling is an essential strategy to realize strong local electromagnetic(EM)field which is crucial for high-performance plasmonic devices.In this work,multiple plasmon couplings are demonstrated in three-dimensional(3D)hybrid plasmonic systems composed of polydimethylsiloxane-supported ordered silver nanocone(AgNC)arrays decorated with high-density gold nanoparticles(AuNPs)which are fabricated by a template-assisted physical vapor deposition process.Strong interparticle coupling,particle-film coupling,inter-cone coupling,and particle-cone coupling are revealed by numerical simulations in such composite nanostructures,which produce intense and high-density EM hot spots,boosting highly sensitive and reproducible surface enhanced Raman scattering(SERS)detection with an enhancement factor of-1.74×10^(8).Furthermore,a linear correlation between logarithmic Raman intensity and logarithmic concentration of probe molecules is observed in a large concentration range.These results offer new ideas to develop novel plasmonic devices,and provide alternative strategy to realize flexible and high-performance SERS sensors for trace molecule detection and quantitative analysis.Zewen Zuo Lianye Sun Yongbin Guo Lujun Zhang Junhu Li Kuanguo Li Guanglei Cui 2022Nano Research2022,15,1:0
19Bound states in the continuum in all-dielectric metasurfaces with scaled lattice constants显示文摘Bound states in the continuum(BICs)have emerged as an efficient tool for trapping light at the nanoscale,promising several exciting applications in photonics.Breaking the structural symmetry has been proposed as an effective way of exciting quasiBICs(QBICs)and generating high-Q resonances.Herein,we demonstrate that QBICs can be excited in an all-dielectric metasurface by scaling the lattice of the metasurface,causing translational symmetry breaking.The corresponding BICs arise from band folding from the band edge to the Γ point in the first Brillouin zone.Multipole analysis reveals that the toroidal dipole dominates these QBICs.Furthermore,scaling the lattice along different directions provides additional freedom for tailoring QBICs,enabling polarization-dependent or-independent QBICs.In addition,this allows the realization of two QBICs at different wavelengths using plane-wave illumination with different polarizations on the metasurface.We experimentally demonstrated the existence of these BICs by fabricating silicon metasurfaces with scaled lattices and measuring their transmission spectra.The vanished resonant linewidth identifies BICs in the transmission spectrum,and the QBICs are characterized by highQ Fano resonances with the Q-factor reaching 2000.Our results have potential applications in enhancing light-matter interaction,such as laser,nonlinear harmonic generation,and strong coupling.Mimi Zhou Shaojun You Lei Xu Menghui Fan Jing Huang Wenbin Ma Mingzhe Hu Shengyun Luo Mohsen Rahmani Ya Cheng Lin Li Chaobiao Zhou Lujun Huang Andrey E.Miroshnichenko 2023Science China(Physics,Mechanics & Astronomy)2023,66,12:0
