1Achieving ultrahigh electrocatalytic NH_(3) yield rate on Fe-doped Bi_(2)WO_(6) electrocatalyst显示文摘NH_(3),derived from electrocatalytic nitrogen reduction reaction(NRR),is promising to satisfy the need of food production and serve as a carbon-free liquid energy carrier in the near future.Yet major challenges remain in enhancing NH_(3) yield rate and conversion efficiency of available electrocatalysts.This work achieved an ultrahigh electrocatalytic NH_(3)yield rate on the_(0.50)Fe-Bi_(2)W0_(6) catalyst by a facile Fe-doped strategy.Up to 289μg·h^(-1)·mg_(cat)^(-1) of NH_(3) formation rate was obtained at-0.75 V vs.RHE,which was reliably quantized by indophenol blue and ^(1)H NMR methods.The impressive result is an order of magnitude higher than that of the reported Fe-and Bi-based catalysts,even more superior than the result of single atom Ru catalyst.The key of the outstanding NRR behaviors on the_(0.50)Fe-Bi_(2)W0_(6) catalyst is the significant hydrogen evolution reaction(HER)suppression and the synergy between Bi and Fe,which can effectively modulate the electron distribution and accelerate the electron transport.This work endows a new insight to further explore the high-performance electrocatalysts toward NRR.Yongqin Liu Liang Huang Youxing Fang Xinyang Zhu Shaojun Dong 2021Nano Research2021,14,8:3
2Amplification and expression of c-MET correlate with poor prognosis of patients with gastric cancer and upregulate the expression of PDL1显示文摘The prognostic significance of c-MET in gastric cancer(GC)remains uncertain.In the present study,we examined the amplification,expression,and the prognostic value of c-MET,human epidermal growth factor receptor 2(HER2),and programmed cell death 1 ligand 1(PDL1),together with the correlations among them in a large cohort of Chinese samples.A total of 444 patients were included.The immunohistochemistry(IHC)and the dual-color silver in situ hybridization(SISH)were performed to examine their expression and amplification.Univariate and multivariate analyses were performed by the Cox proportional hazard regression model,and survival curves were estimated by the Kaplan-Meier method.The positivity determined by IHC of c-MET was 24.8%,and the MET amplification rate was 2.3%.The positivity rates of HER2 and PDL1 were 8%and 34.7%,respectively.PDL1 expression had a significantly positive association with c-MET expression.c-MET positivity played a significant prognostic role in disease-free survival(DFS)(P=0.032).Patients with mesenchymal-epithelial transition(MET)amplification had significantly poorer prognosis on both DFS and overall survival(OS).Subgroup analysis showed that in HER2-negative patients,but not in HER2-positive patients,MET-positive patients had significantly worse DFS(P=0.000)and OS(P=0.006).c-MET regulated the expression of PDL1 through an AKT-dependent pathway.c-MET inhibitor enhanced the T-cell killing ability and increased the efficacy of PD1 antibody.c-MET was found to be an independent prognostic factor for DFS of GC patients.A combination of c-MET inhibitors and PD1 antibodies could enhance the killing capacity of T cells,providing a preliminary basis for the clinical research on the same combination in GC treatment.Ya’nan Yang Chenchen Wang Congqi Dai Xinyang Liu Wenhua Li Mingzhu Huang Xiaoying Zhao Dongmei Ji Jin Li Weijian Guo 2021Acta Biochimica et Biophysica Sinica2021,53,5:2
3Flotation performance of a novel Gemini collector for kaolinite at low temperature显示文摘How to sustainably produce bauxite by effective reverse froth flotation of kaolinite at low temperature is an urgent problem to be solved in the field of mineral processing.In this work,a novel amino-based Gemini surfactant butadiyl-1,4-bis(dimethyl dodecylammonium bromide)(BBDB) was prepared and first utilized as a novel collector for kaolinite flotation.Its flotation performance for kaolinite was compared with that of the common monomolecular surfactant 1-dodecylamine(DDA) by micro-flotation tests.The tests results indicated that 95% kaolinite recovery was obtained using 2.0×10^(-4) mol/L BBDB at 25℃ which was half of the dosage when DDA obtained the maximum kaolinite recovery of81%.At extremely low temperature(0℃),3.0×10^(-4) mol/L BBDB could still collect 91% kaolinite,while DDA showed a frustrating ability.The contact angle tests indicated that BBDB could still significantly improve the hydrophobicity of the kaolinite surface(contact angle 71.7°) than DDA(contact angle only25.8°) at 0℃.The Krafft point comparison tests indicated that BBDB had a much lower Krafft point(below0℃) than DDA.Fourier transform infrared spectroscopy(FTIR)-spectrum analysis and zeta potential measurements showed that BBDB was physically adsorbed on the surface of kaolinite through electrostatic interaction.Shiyong Zhang Zhiqiang Huang Hongling Wang Rukuan Liu Chen Cheng Shuyi Shuai Yajing Hu Zhiqun Guo Xinyang Yu Guichun He Weng Fu 2021International Journal of Mining Science and Technology2021,31,6:2

5Differential transcriptomic landscapes of multiple organs from SARS-CoV-2 early infected rhesus macaques显示文摘SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries,how-ever,the underlying mechanism,in particular immune responses in different organs,remains elusive.In this study,comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed.Compared to normal controls,SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs,with drastic transcriptomic changes in cerebral cortex and right ventricle.Intriguingly,cerebral cortex exhibited a hyperinflammatory state evidenced by sig-nificant upregulation of inflammation response-related genes.Meanwhile,expressions of coagulation,angio-genesis and fibrosis factors were also up-regulated in cerebral cortex.Based on our findings,neuropilin 1(NRP1),a receptor of SARS-CoV-2,was significantly elevated in cerebral cortex post infection,accompanied by active immune response releasing inflammatory factors and signal transmission among tissues,which enhanced infection of the central nervous system(CNS)in a positive feedback way,leading to viral encephalitis.Overall,our study depicts a multi-tissue/organ tran-scriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2,and provides important insights into the mechanistic basis for COVID-19-asso-ciated clinical complications.Chun-Chun Gao Man Li Wei Deng Chun-Hui Ma Yu-Sheng Chen Yong-Qiao Sun Tingfu Du Qian-Lan Liu Wen-Jie Li Bing Zhang Lihong Sun Si-Meng Liu Fengli Li Feifei Qi Yajin Qu Xinyang Ge Jiangning Liu Peng Wang Yamei Niu Zhiyong Liang Yong-Liang Zhao Bo Huang Xiao-Zhong Peng Ying Yang Chuan Qin Wei-Min Tong Yun-Gui Yang 2022Protein & Cell2022,13,12:1
6Preparation of cinnamic hydroxamic acid collector and study on flotation characteristics and mechanism of scheelite显示文摘In this paper,using methyl cinnamate as raw material,the new cinnamic hydroxamic acid collector(CIHA)was synthesized by the hydroxylamine method.The collector performance of hydroxamic acid was investigated for scheelite and gangue calcite,and the flotation separation test of scheelite and calcite was carried out with CIHA as the collector.The interaction mechanism between hydroxamic acid and scheelite minerals has also been investigated through zeta potential,Fourier transform infrared spectroscopy(FTIR)experiments,X-ray photoelectron spectroscopy(XPS)experiments,and density functional theory(DFT)calculation.The single mineral flotation test and artificially mixed ore showed that CIHA had an excellent collection effect and selectivity.Zeta potential,FTIR,and XPS showed that CIHA was adsorbed on the scheelite surface by strong chemical adsorption.The active group of CIHA was analyzed through quantum chemical calculation.It was speculated that C=O and N-O bonds could synthesize a five-membered chelated hydroxamic acid group with Ca element chelate on scheelite surface,changing hydrophobicity and making it more likely to emerge from the pulp.Xiang Yao Xinyang Yu Liping Wang Yuhui Zeng Linghan Mao Shanming Liu Honghui Xie Guichun He Zhiqiang Huang Zhilin Liu 2023International Journal of Mining Science and Technology2023,33,6:1

8Synthesis and formation mechanism of HfB_(2) ultrafine powders with low oxygen via flocculating settling assisted process and carbo/borothermal reduction显示文摘In this study,ultrafine HfB_(2) powders with low oxygen were synthesized by a flocculating settling process which yielded ceramic precursors and subsequent carbo/borothermal reduction of the precursors.The liquid phase precursor method can achieve uniform mixing of components at the molecular level through multiple complexation reactions,and then realize the carbo/borothermal reduction reaction at a lower temperature to obtain ultrapure HfB2 powders.The as-resulted quasi-spherical HfB2 powders under the optimum conditions(atomic molar ratio M:B:C=1:2.8:10)calcined at 1500°C for 1 h have an average particle size of 205 nm and an oxygen content of 0.097 wt.%.Detailed analysis of the phase evolution of precursors shows that the formation of HfB2 particles is a mass diffusion mode from the external to internal HfO_(2)cores.We reveal that below 1300°C,HfC is not an intermediate product of HfB2 powder during the transition of precursors.Instead,HfC was formed as a by-product at high temperatures in the carbo/borothermal reduction process.The proposed formation mechanism of HfB_(2) is completely different from the traditional two-step transformation method.After the sintering of the ultrafine powders,the HfB_(2) ceramics show a relative density of 96.1%and superior mechanical properties compared to other works.Furthermore,by simply replacing the initial metal source,chlorinated group IV and V transitional metals(Ti,Zr,Ta,Nb)can also convert into high-purity and ultrafine diborides.This work shows that flocculating settling assisted carbo/borothermal reduction has potential in lot size production of various high-purity and ultrafine boride powders.Zhen Wang Yuan Cheng Kewei Li Tianxu Wang Mengen Hu Chunxue Zheng Xinyang Li Zhulin Huang Xiaoye Hu Yue Li Xinghong Zhang 2023Journal of Materials Science & Technology2023,,33:0
9Air target intention recognition and causal effect analysis combining uncertainty information reasoning and potential outcome framework显示文摘Recognizing target intent is crucial for making decisions on the battlefield.However,the imperfect and ambiguous character of battlefield situations challenges the validity and causation analysis of classical intent recognition techniques.Facing with the challenge,a target intention causal analysis paradigm is proposed by combining with an Intervention Retrieval(IR)model and a Hybrid Intention Recognition(HIR)model.The target data acquired by the sensors are modelled as Basic Probability Assignments(BPAs)based on evidence theory to create uncertain datasets.Then,the HIR model is utilized to recognize intent for a tested sample from uncertain datasets.Finally,the intervention operator under the evidence structure is utilized to perform attribute intervention on the tested sample.Data retrieval is performed in the sample database based on the IR model to generate the intention distribution of the pseudo-intervention samples to analyze the causal effects of individual sample attributes.The simulation results demonstrate that our framework successfully identifies the target intention under the evidence structure and goes further to analyze the causal impact of sample attributes on the target intention.Yu ZHANG Fanghui HUANG Xinyang DENG Mingda LI Wen JIANG 2024Chinese Journal of Aeronautics2024,37,1:0
10Variation in Bombyx mori immune response against fungal pathogen Beauveria bassiana with variability in cell wallβ-1,3-glucan显示文摘Entomopathogenic fungi are protected by a cell wall with dynamic structure for adapting to various environmental conditions.β-1,3-Glucan recognition proteins activate the innate immune system of insects by recognizing surface molecules of fungi.However,the associations between pathogenicity and the different components of entomopathogenic fungal cell walls remain unclear.Three Beauveria bassiana strains were selected that have significantly differing virulence against Bombyx mori.The molecular mechanisms underlying the immune response in B.mori were investigated using RNA sequencing,which revealed differences in the immune response to different B.bassiana strains at 12 h post-infection.Immunofluorescence assays revealed thatβ-1,3-glucan content had an opposite trend to that of fungal virulence.β-1,3-Glucan injection upregulated BmβGRP4 expression and significantly reduced the virulence of the high-virulence strain but not that of the medium-virulence or low-virulence strains.BmβGRP4 silencing in B.mori with RNA interference resulted in the opposite virulence pattern,indicating that the virulence of B.bassiana was affected by the cell walls’content ofβ-1,3-glucan,which could be recognized by BmβGRP4.Furthermore,interference with the gene CnA(calcineurin catalytic A subunit)involved inβ-1,3-glucan synthesis eliminated differences in virulence between B.bassiana strains.These results indicate that strains of a single species of pathogenic fungi that have differing cell wall components are recognized differently by the innate immune system of B.mori.Yulong Wang Zhen Liu Xuebing Yin Shihong Liu Kai Wang Rongjie Wan Haoran Chen Xinyang Li Bo Huang 2024Insect Science2024,31,1:0
11Flotation separation of wolframite from calcite using a new trisiloxane surfactant as collector显示文摘Since wolframite is usually associated with calcite,the separation and enrichment of wolframite by froth flotation remains a great challenge.Herein,a novel trisiloxane surfactant N-(2-aminoethyl)-3-ami nopropyltrisiloxane(AATS)was successful synthesized,which was used for the separation of wolframite from calcite for the first time.The flotation separation performance of AATS was studied by flotation test,and its adsorption mechanism was explored based on contact angle,infrared spectrum analysis(FTIR),zeta potential and density functional theory(DFT)calculation.The results of microflotation test and binary mixed ore flotation test pointed that AATS had excellent selectivity and more prominent collection capacity for the flotation of wolframite when compared with industrial reagent sodium oleate(NaOL).The measurement results of contact angle proved that AATS improved the hydrophobicity of the wolframite surface.The highly selective adsorption mechanism of AATS surfactant on mineral surfaces were further researched and analyzed by FTIR and zeta potential.The results revealed that AATS surfactant had significant adsorption effect on wolframite,yet almost no adsorption on calcite.DFT calculation indicated that AATS produced electrostatic adsorption with wolframite surface through—N+H3 group.Shuyi Shuai Zhiqiang Huang Vladimir E.Burov Vladimir Z.Poilov Fangxu Li Hongling Wang Rukuan Liu Shiyong Zhang Chen Cheng Wenyuan Li Xinyang Yu Guichun He Weng Fu 2023International Journal of Mining Science and Technology2023,33,3:0
12Screening and identifying natural products with SARS-CoV-2 infection inhibitory activity from medicinal fungi显示文摘The coronavirus disease of 2019(COVID‐19),a global pandemic caused by the severe acute respiratory syndrome coronavirus 2(SARS‐CoV‐2),can result in severe health complications.In addition to physical preventative measures,pharmaceutical intervention is also crucial.Numerous natural products from medicinal fungi have shown promise as potential antiviral drugs and may serve as a source of effective components with antiviral activity against SARS‐CoV‐2 and other coronaviruses.In this study,we developed a workflow that integrates viral infection inhibition assays at both cellular and molecular levels,as well as molecular separation and characterization,to screen and identify natural products with antiviral activity.Using this workflow,we screened 167 extracts extracted from 36 medicinal fungi using optimized extraction methods.We assessed the antiviral effects of these extracts by measuring their ability to inhibit SARS‐CoV‐2 infection and receptor binding domain‐human angiotensin‐converting enzyme 2(RBD‐hACE2)binding in vitro.Following charge‐and size‐based characterization of the active compounds through filtration and chromatographic fractionation,mass spectrometry characterization of the fractionated compounds revealed that the active components are polysaccharides and determined their monosaccharide residue composition.Our findings provide new insights into the antiviral potential of natural products and their screening strategies and may contribute to the development of effective antiviral therapeutics against COVID‐19 and other diseases.Shuang Zhao Amelia Siqi Huang Weibo Zhang Lili Ren Hexiang Wang Jianbin Wang Xinyang Shao Guanbo Wang 2024Biosafety and Health2024,6,1:0

14Analysis on Heterosis and Combining Ability of Main Agronomic Characteristics in Huang-Huai-Hai Summer Soybean显示文摘With 10 elite soybean varieties from Huang-Huai-Hai Valleys as materials,25 hybridization combinations were compounded based on NC II,and the heterosis and combining ability for the major agronomic characters in summer soybean was studied.The results showed that heterosis of agronomic traits of soybean was ubiquity,and the average heterosis of all characters showed positive advantages.The advantage of seed weight per plant,number of seeds per plant and number of pods per plant were the highest,at 35.58%,34.23%and 31.47%,respectively,and thus made a great contribution to yield heterosis.The general combining ability of Hedou 19,Handou 6,Shanning 14 and Williams 82 was relatively higher in seed weight per plant,number of seeds per plant and number of pods per plant,and they are quality parents for designing strong hybridization combinations.There were significant differences in special combining ability(SCA)among parents for the same trait in different combinations.Some showed positive effect,and others showed negative effects.We should select the best combination according to breeding objective in selecting and matching special elite combinations.Xinyang HUANG Enhai ZHAO Jing ZHOU Yanzheng ZHOU Yun ZHAO Xu YANG Jicun LI Suzhen LI 2022Agricultural Biotechnology2022,11,6:0
15Aminoacyl-tRNA Synthetase-based Prognosis Model and Exploration of Potential Mechanisms in Hepatocellular Carcinoma显示文摘Background and Aims:Aminoacyl-tRNA synthetases(ARSs)participate in tumor initiation and progression but their involvement in hepatocellular carcinoma(HCC)is not clear.This study aimed to investigate the prognostic value and underlying mechanisms of ARS in HCC.Methods:Data were obtained from The Cancer Genome Atlas(TCGA),International Cancer Genome Consortium,Gene Expression Omnibus and Human Protein Atlas databases.The prognostic model was constructed with the use of Cox regression and least absolute shrinkage and selection operator regression.Kaplan-Meier survival analysis,enrichment analysis,single sample gene set enrichment analysis and tumor mutation burden calculation were performed with R to evaluate the model and explore the underlying mechanism.Wilcoxon tests were used for comparisons between groups.Results:Aspartyl-tRNA synthetase 2(DARS2),tyrosyl-tRNA synthetase 1(YARS1)and cysteinyl-tRNA synthetase 2(CARS2)were identified as prognostic biomarkers and enrolled in model construction.The area under receiver operating characteristic curve of the model was 0.775.The model was used to assign patients from TCGA into low-and high-risk groups.Those in the high-risk group had a worse prognosis(p<0.001).The clinical significance of the model was tested in different clinical subgroups.Genetic mutation analysis had a higher TP53 mutation frequency in high-risk group.Enrichment analysis and study of immune-related cells and molecules found that the high-risk group was characterized by immune-cell infiltration and immunosuppression states.Conclusions:A novel ARS family-based model of HCC prognosis was constructed.TP53 mutation frequency and immune-suppressive status accounted for a worse prognosis in patients included in the high-risk group.Yixun Jin Xinyang Huang Zhuoxin Wang Hui Xu Qi Wang Lifu Wang 2023Journal of Clinical and Translational Hepatology2023,11,4:0
16Response of plant,litter,and soil C:N:P stoichiometry to growth stages in Quercus secondary forests on the Loess Plateau,China显示文摘Ecological stoichiometry is an important indicator of biogeochemical cycles and nutrient limitations in terrestrial ecosystems.However,little is known about the response of ecological stoichiometry to plant growth.In this study,carbon(C),nitrogen(N),and phosphorus(P)concentrations were evaluated in plant tissues(trees,shrubs,and herbs),litter,and soil of young(≤40-year-old),middle-aged(41–60-year-old),near-mature(61–80-year-old),and mature(81–120-year-old)Quercus secondary forests on the Loess Plateau,China.Vegetation composition,plant biomass,and C stock were determined to illustrate their interaction with stoichiometry.Only tree biomass C signifi cantly increased with stand development.Leaf N and trunk P concentrationsgenerally increased,but branch P decreased with growth stage.Fine roots had the highest C and P concentrations at the middle-aged stage.In contrast,shrubs,herbs,litter,and soil C:N:P stoichiometry did not change signifi cantly during stand development.Leaf N and P were positively correlated with soil C,N,P,and their ratios.However,there was no signifi cant correlation between litter and leaves in terms of C:N:P stoichiometry.A redundancy analysis showed that soil N best explained leaf N and P variance,and tree biomass and C stock were related to biotic factors such as tree age and shrub biomass.Hierarchical partitioning analysis indicated that,compared with soil or litter variables,stand age only accounted for a relatively small proportion of leaf C,N,and P variation.Thus,secondary Quercus ecosystems might have inherent ability to maintain sensitive responses of metabolically active organs to environmental factors during stand aging.The results of this work help to elucidate the biogeochemical cycling of secondary forest ecosystems in tree development,provide novel insights into the adaptation strategies of plants in diff erent organs and growth stages,and could be used to guide fertilization programs and optimize forest structure.Juanjuan Zhang Xinyang Li Meng Chen Linjia Huang Ming Li Xu Zhang Yang Cao 2023Journal of Forestry Research2023,34,3:0
17Effect of Particle Orientation on Heat Transfer in Arrays of Prolate Particles显示文摘Direct Numerical Simulations have been carried out to study the forced convection heat transfer of flow through fixed prolate particles for a variety of aspect ratios ar={5/4,5/3,5/1}with Reynolds number(Re)up to 100.Three variations of the solid volume fraction c={0.1,0.2,0.3}with four Hermans orientation factors S={−0.5,0,0.5,1}are studied.It has been found that changes in S cause prominent variations in the Nusselt number.In general,Nusselt number increases with the decrease of S.For all three aspect ratios,the Nusselt number remains a linear function of S at different c and Re.Therefore,it is concluded that,for heat transfer from prolate muti-particle system,the effects of orientations cannot be ignored.A new correlation for Nusselt number has been developed for arrays of prolate particles using the simulation data as a function of Re,c,S and ar.Romana Basit Xinyang Li Zheqing Huang Qiang Zhou 2023Computer Modeling in Engineering & Sciences2023,,8:0
