2Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration.Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen 2019National Science Review2019,6,4:21

4Brain cell apoptosis and enhancement of nervous excitability in pregnant rats with high plasma levels of homocysteine显示文摘Hyperhomocysteinemia is an important risk factor for preeclampsia-eclampsia. This study established a pregnant rat model of hyperhomocysteinemia, in which blood plasma homocysteine concentrations were twice or three times greater than that of normal pregnant rats. TUNEL revealed an increase in the number of apoptotic cells in the frontal cortex of pregnant rats with hyperhomocysteinemia. In addition,immunohistochemical staining detected activated nuclear factor-κB-positve cells in the frontal cortex.Reverse transcription-PCR detected that mRNA expression of the anti-apoptotic gene bcl-2 diminished in the frontal cortex. In situ hybridization and western blotting revealed that N-methyl-D-aspartate receptor 1 mRNA and protein expression was upregulated in the frontal cortex and hippocampus. These results indicate that hyperhomocysteinemia can induce brain cell apoptosis,increase nerve excitability, and promote the occurrence of preeclampsia in pregnant rats.Jun Wang Jing Ge Liu Yang Haiyan Zhang Xuli Li Dan Xue 2012Neural Regeneration Research2012,7,28:2

6Enhanced dynamic deformability and strengthening effect via twinning and microbanding in high density NiCoFeCrMoW high-entropy alloys显示文摘High density alloys with enhanced deformability and strength are urgently required in energy,military and nuclear industries,etc.In this work,we present a new kind of NiCoFeCrMoW high entropy alloys(HEAs)which possess higher densities and sound velocities than copper.We systematically investigate the phase structure,quasi-static tensile,dynamic compression and related deformation mechanism of these HEAs.It is shown that single FCC or FCC+μdual phases were formed in the HEAs depending on Mo and W content and annealing temperature.Excellent quasi-static tensile and dynamic compression properties have been achieved for these HEAs,e.g.Ni_(30)Co_(30)Fe_(21)Cr_(10)W_(9)HEA annealed at 1573 K exhibited a yield and ultimate tensile strength and elongation of~364 MPa,~866 MPa and~32%,respectively,in quasi-static test;a yield strength of~710 MPa and no fracture under the dynamic strain rate of 4100 s^(-1).Superior strain rate sensitivity(SRS)of yield strength than that of previously reported FCC HEAs have been evidenced.The dynamic stress-strain constitutive relation can be described by the modified Johnson-Cook model.As for the dynamic deformation mechanism,it is envisaged that the regulation of stacking fault energy and Peierls barrier in current HEAs resulted in occurrences of abundant nanoscale deformation twins and microbands during high strain rate compression.The synergistic microbanding and twinning effectively contributes to the enhanced dynamic deformability and strengthening effect.Besides,the interactions of dislocations with precipitates,stacking faults(SFs)with twins,and between SFs also contribute to extraordinary work-hardening capacity.Xuli Liu Yidong Wu Yansong Wang Jinbin Chen Rui Bai Lei Gao Zhe Xu William Yi Wang Chengwen Tan Xidong Hui 2022Journal of Materials Science & Technology2022,,32:1

12Nascent Polypeptide-Associated Complex Involved in the Development and Pathogenesis of Fusarium graminearum on Wheat显示文摘Reliable knowledge on pathogenic agents contributes to effective plant protection.For most plant pathogens,maintaining protein homeostasis(proteostasis)is essential for unfolding the cellular functions to survive and thrive.However,the fungal proteins involved in proteostasis remain poorly characterized in the process of pathogenesis.In this study,we characterized the function of the nascent polypeptideassociated complex(NAC)in Fusarium graminearum(F.graminearum)(FgNAC),one of the top 10 fungal pathogens with predominant scientific/economic importance.We found that FgNACa,a subunit of FgNAC,manifests high structural and functional similarity to its homologous counterparts in yeast and other species.The mutants of F.graminearum lacking NACa are viable but suffer significant defects in vegetative growth,conidial production,and pathogenesis.In addition,we show here that FgNACa can interact with another subunit of NAC(FgNACb)in a yeast-two-hybrid assay.The subcellular localization results show that FgNACa and FgNACb are predominantly localized in the cytoplasm.Future studies should focus on deciphering the mechanism by which NAC orchestrates protein biogenesis and consequentially modulates development and pathogenesis.Xuli Wang Xin Xie Jin Liu Guo-Liang Wang Dewen Qiu 2020Engineering2020,6,5:0
13Protein-assisted conjugated polymer microarray: Fabrication and sensing applications显示文摘A new strategy is performed to fabricate conjugated polymer microarray with the assistance of protein in this work.The water-soluble cationic conjugated polymer employed in the present work is capable of absorbing light at 510 nm,which makes it compatible with a variety of commercial microarray scanners.It is demonstrated that the protein-assisted conjugated polymer microarray exhibits higher fluorescence signal and better stability in comparison with the case without protein.The conjugated polymer microarray can be used for sensitive detection of picric acid(PA).A major advantage of our approach is its simplicity and chemical linking is not required between the conjugated polymer and microarray substrate.Considering the simplicity of the preparation of the conjugated polymer microarray,it is anticipated that novel sensing platforms will be constructed by employing this versatile method.Lü FengTing FENG XuLi LIU LiBing WANG Shu 2013Chinese Science Bulletin2013,58,33:0
14Programmable dual responsive system reconstructing nerve interaction with small-diameter tissue-engineered vascular grafts and inhibiting intimal hyperplasia in diabetes显示文摘Small-diameter tissue-engineered vascular grafts(sdTEVGs)with hyperglycemia resistance have not been constructed.The intimal hyperplasia caused by hyperglycemia remains problem to hinder the patency of sdTEVGs.Here,inspired by bionic regulation of nerve on vascular,we found the released neural exosomes could inhibit the abnormal phenotype transformation of vascular smooth muscle cells(VSMCs).The transformation was a prime culprit causing the intimal hyperplasia of sdTEVGs.To address this concern,sdTEVGs were modified with an on-demand programmable dual-responsive system of ultrathin hydrogels.An external primary Reactive Oxygen Species(ROS)-responsive Netrin-1 system was initially triggered by local inflammation to induce nerve remolding of the sdTEVGs overcoming the difficulty of nerve regeneration under hyperglycemia.Then,the internal secondary ATP-responsive DENND1A(guanine nucleotide exchange factor)system was turned on by the neurotransmitter ATP from the immigrated nerve fibers to stimulate effective release of neural exosomes.The results showed nerve fibers grow into the sdTEVGs in diabetic rats 30 days after transplantation.At day 90,the abnormal VSMCs phenotype was not detected in the sdTEVGs,which maintained long-time patency without intima hyperplasia.Our study provides new insights to construct vascular grafts resisting hyperglycemia damage.Yanzhao Li Yeqin Wang Fangchao Xue Xuli Feng Zhaojing Ba Junjie Chen Zhenhua Zhou Yanhong Wang Ge Guan Guanyuan Yang Ziwei Xi Hao Tian Yong Liu Ju Tan Gang Li Xiewan Chen Mingcan Yang Wen Chen Chuhong Zhu Wen Zeng 2022Bioactive Materials2022,7,1:0
15Effect of lipid peroxidation on the allergenicity and functional properties of soybeanβ-conglycinin(7S)and glycinin(11S)显示文摘This study aimed to analyze the effect of lipid peroxidation on the allergenicity and functional properties of soybeanβ-conglycinin(7 S)and glycinin(11 S).Oxidation complexes were determined using the lipid peroxidation method.Functional properties were analyzed based on emulsifying and foaming properties.The potential allergenicity was evaluated by in vitro and in vivo methods.The results found that oxidation altered structures of the proteins and resulted in the formation of cross-linked protein polymers.The emulsion and foaming properties of the proteins were improved after oxidation.The IgE-binding capacity of 7 S and11 S reduced after oxidation.KU812 cell assays showed that both histamine and IL-4 release decreased after oxidation treatment.A mouse model showed that oxidation reduced the IgE,IgG,and IgG1 levels,as well as reduced histamine and mMCP-1 release in serum,which might suppress the allergic reaction.In conclusion,the lipid peroxidation treatment likely causes changes to the functional properties of soybean,decreasing the potential allergenicity of 7 S and 11 S.Liying Ye Liangtao Lv Xiao Lin Kan He Xiaoquan Yang Zhili Wan Lizhong Liu Haiqian Wu Shaojun Xing Xuli Wu 2023Food Science and Human Wellness2023,12,3:0
16Self-gating enhanced carrier transfer in semiconductor electrocatalyst verified in microdevice显示文摘Semiconductor electrocatalysis with weak conductivity can accumulate extremely high carriers at semiconductor-electrolyte interface by self-gating effect,which strongly promotes electrocatalytic efficiency.The correlation between semiconductor carrier mobility and electrocatalysis performance is still unclear.Herein atomic-thin transition metal dichalcogenides based composites have been developed for hydrogen evolution reaction(HER)performed with on-chip microdevices.Electrical and electrochemical measurement of individual flack verified the key role of high carrier mobility for enhanced HER activity.Carrier mobility regulation further demonstrated its high dependence with HER performance under self-gating.Our study provides new insight into the carrier mobility of the semiconductor in the electrocatalysis,paving the way for designing high-performance semiconductor catalysts.Haiyan Xiang Yueshao Zheng Yang Chen Yanting Xu Travis Shihao Hu Yexin Feng Yu Zhou Song Liu Xuli Chen 2022Chinese Chemical Letters2022,33,6:0
17MDR1-targeted siRNA delivery with cationic dendritic conjugated polymers显示文摘A cationic dendritic polyfluorene (PFP) is examined as a siRNA delivery vector. This material was designed to facilitate the nucleic acid binding, encapsulation and efficient cellular uptake. PFP can effectively protect siRNA against nuclease degradation, which is necessary for gene carriers. PFP can be used for multidrug resistance gene-targeted siRNA delivery in doxorubicin (Dox)-resistant human breast cancer cells (MCF7) cells. As a siRNA transfection agent, PFP can efficiently achieve the reversal of drug resistance and enhance the drug sensitivity. These new features and capabilities represent a major step toward conjugated polymers that can function for therapeutic application.FENG XuLi Lü FengTing LIU LiBing WANG Shu 2013Chinese Science Bulletin2013,58,22:0
18High performance wide bandgap perovskite solar cell with low V_(OC)deficit less than 0.4 V显示文摘Wide bandgap perovskite solar cells(PSCs)have attracted significant attention because they can be applied to the top cells of tandem solar cells.However,high open-circuit voltage(V_(OC))deficit(>0.4 V)result from poor crystallization and high non-radiative recombination losses become a serious limitation in the pursuit of high performance.Here,the relevance between different Pbl_(2)proportions and performance parameters are revealed through analysis of surface morphology,residual stress,and photostability.The increase of Pbl_(2)proportion promotes crystal growth and reduces the work function of the perovskite film surface and promotes the energy level alignment with the carrier transport layer,which decreased the V_(OC)deficit.However,residual PbI_(2)exacerbated the stress level of perovskite film,and the resulting lattice disorder deteriorated the photostability of the device.Ultimately,after the synergistic passivation of residual PbI_(2)and PEAI,the V_(OC)achieves 1.266 V and V_(OC)deficit is less than 0.4 V,the record value in wide bandgap PSCs.Haikuo Guo Fuhua Hou Xuli Ning Xiaoqi Ren Haoran Yang Rui Liu Tiantian Li Chengjun Zhu Ying Zhao Wei Li Xiaodan Zhang 2024Journal of Energy Chemistry2024,91,4:0
19Plant community and soil properties drive arbuscular mycorrhizal fungal diversity:A case study in tropical forests显示文摘The mutual interdependence of plants and arbuscular mycorrhizal fungi(AMF)is important in carbon and mineral nutrient exchange.However,an understanding of how AMF community assemblies vary in different forests and the underlying factors regulating AMF diversity in native tropical forests is largely unknown.We explored the AMF community assembly and the underlying factors regulating AMF diversity in a young(YF)and an old-growth forest(OF)in a tropical area.The results showed that a total of 53 AMF phylogroups(virtual taxa,VTs)were detected,38±1 in the OF and 34±1 in the YF through high-throughput sequencing of 18S rDNA,and AMF community composition was significantly different between the two forests.A structural equation model showed that the forest traits indirectly influenced AMF diversity via the plant community,soil properties and microbes,which explained 44.2%of the total observed variation in AMF diversity.Plant diversity and biomass were the strongest predictors of AMF diversity,indicating that AMF diversity was dominantly regulated by biotic factors at our study sites.Our study indicated that forest community traits have a predictable effect on the AMF community;plant community traits and soil properties are particularly important for determining AMF diversity in tropical forests.Jing Zhang Changxin Quan Lingling Ma Guowei Chu Zhanfeng Liu Xuli Tang 2021Soil Ecology Letters2021,3,1:0
