| 1 | Regulation of phenylpropanoid biosynthesis by MdMYB88 and MdMYB124 contributes to pathogen and drought resistance in apple显示文摘MdMYB88 and MdMYB124 have been demonstrated to be responsible for lignin accumulation in apple under drought stress.In this study,using a metabolomic approach,we identified differentially accumulated phenylpropanoid and flavonoid metabolites in MdMYB88/124 transgenic RNAi plants under control and long-term drought stress conditions in apple roots.We confirmed the regulation of phenylalanine by MdMYB88 and MdMYB124 via UPLC-MS in apple roots under both control and drought conditions.Using Electrophoretic Mobility Shift Assay(EMSA)and ChIPquantitative PCR(qPCR)analyses,we found that MdMYB88 positively regulates the MdCM2 gene,which is responsible for phenylalanine biosynthesis,through binding to its promoter region.Under long-term drought conditions,MdMYB88/124 RNAi plants consistently accumulated increased amounts of H2O2 and MDA,while MdMYB88 and MdMYB124 overexpression plants accumulated decreased amounts of H2O2 and MDA.We also examined the accumulation of metabolites in the phenylpropanoid biosynthesis pathway in the leaves of MdMYB88 and MdMYB124 transgenic apple plants after long-term drought stress.We found that metabolites responsible for plant defense,including phenylpropanoids and flavonoids,accumulated less in the RNAi plants but more in the overexpression plants under both control and drought conditions.We further demonstrated that MdMYB88/124 RNAi plants were more sensitive to Alternaria alternata f.sp.mali and Valsa mali,two pathogens that currently severely threaten apple production.In contrast,MdMYB88 and MdMYB124 overexpression plants were more tolerant to these pathogens.The cumulative results of this study provided evidence for secondary metabolite regulation by MdMYB88 and MdMYB124,further explained the molecular roles of MdMYB88 and MdMYB124 in drought resistance,and provided information concerning molecular aspects of their roles in disease resistance. | Dali Geng Xiaoxia Shen Yinpeng Xie Yusen Yang Ruiling Bian Yuqi Gao Pengmin Li Liying Sun Hao Feng Fengwang Ma Qingmei Guan | 2020 | Horticulture Research2020,7,1: | 5 |
| 2 | Noncontrast-enhanced MRI-based Noninvasive Score for Portal Hypertension(CHESS1802):An International Multicenter Study显示文摘Background and Aims:This study aimed to determine the performance of the non-invasive score using noncontrastenhanced MRI(CHESS-DIS score)for detecting portal hy-pertension in cirrhosis.Methods:In this international multicenter,diagnostic study(ClinicalTrials.gov,NCT03766880),patients with cirrhosis who had hepatic venous pressure gradient(HVPG)measurement and noncontrast-enhanced MRI were prospectively recruited from four university hospitals in China(n=4)and Turkey(n=1)between December 2018 and April 2019.A cohort of patients was retrospectively recruited from a university hospital in Italy between March 2015 and November 2017.After segmentation of the liver on fat-suppressed T1-weighted MRI maps,CHESS-DIS score was calculated automatically by an in-house developed code based on the quantification of liver surface nodularity.Results:A total of 149 patients were included,of which 124 were from four Chinese hospitals(training cohort)and 25 were from two international hospitals(validation cohort).A positive correlation between CHESS-DIS score and HVPG was found with the correlation coefficients of 0.36(p<0.0001)and 0.55(p<0.01)for the training and validation cohorts,respectively.The area under the receiver operating characteristic curve of CHESS-DIS score in detection of clinically significant portal hypertension(CSPH)was 0.81 and 0.9 in the training and validation cohorts,respectively.The intra-class correlation coefficients for assessing the inter-and intra-observer agreement were 0.846 and 0.841,respectively.Conclusions:A non-invasive score using noncontrast-enhanced MRI was developed and proved to be significantly correlated with invasive HVPG.Besides,this score could be used to detect CSPH in patients with cirrhosis. | Yanna Liu Tianyu Tang NecatiÖrmeci Yifei Huang Jitao Wang Xiaoguo Li Zhiwei Li Weimin An Dengxiang Liu Chunqing Zhang Changchun Liu Jinqiang Liu Chuan Liu Guangchuan Wang Cristina Mosconi Alberta Cappelli Antonio Bruno Seray Akçalar EmrecanÇelebioğlu EvrenÜstüner Sadık Bilgiç Zeynep Ellik ÖzgünÖmer Asiller Lei Li Haijun Zhang Ning Kang Dan Xu Ruiling He Yan Wang Yang Bu Ye Gu Shenghong Ju Rita Golfieri Xiaolong Qi | 2021 | Journal of Clinical and Translational Hepatology2021,9,6: | 3 |
| 3 | Bismuth doped lead-free two-dimensional tin based halide perovskite single crystals显示文摘Heterovalent-metal doping is an efficient tool to tune the optoelectronic properties of the famous halide perovskites.Previous studies have focused on the heterovalent-doping in three-dimensional(3D) halide perovskites.However, there is a lack of such doping in two-dimensional perovskites which possess unique optoelectronic properties and improved chemical stability as compared to 3D analogues.Here, we present successful doping of Bismuth into the lattice of lead-free, two-dimensional perovskite PEA2SnBr4 single crystals.Structural characterizations demonstrate that the doped crystals possess identical crystal structure and layered morphology with the pristine one.Intriguingly, we find the PL peak and spectral shape can be tailored by tuning the concentration of Bi dopants.Femtosecond transient absorption spectroscopy is performed to understand the underlying mechanism related to tunable PL behaviors, and a clear picture of the Bismuth-doping impact is provided. | Ruiling Zhang Xin Mao Pengfei Cheng Yang Yang Songqiu Yang Tuerdi Wumaier Weiqiao Deng Keli Han | 2019 | Journal of Energy Chemistry2019,28,9: | 2 |

| 5 | Theoretical analysis and applications of Y-Inversion Ventilation System in a mine fire zone显示文摘Based on mine fire fighting practices at the 1110 working face of the Brapukuria Coal Mine,Bangladesh,we introduce and discuss the Y-Inversion Ventilation System,the latest technology used both in mine fire zone management and the unsealing process.This ventilation system can ensure that all miners breathed fresh air,providing protection for them during fire fighting and unsealing the fire zone.On the other hand,adjusting the amount of air at the working face and forming a CO leakage path controlled the state of the fire and as well ensured that the different fire extinguishing measures could be applied successfully.These are all fundamental techniques which ensured successful fire extinguishing and unsealing of the fire zone.We also analyzed the main reasons for the spontaneous coal combustion that occurred at the 1110 working face.Successful application of advanced composite polymer colloidal perfusion techniques,polymer foam MEA perfusion and fire-prevention technology by infusing nitrogen,used in mine fire zone management and unsealing,are presented.We value the experience with these techniques very highly and are of the opinion that these techniques could be widely used in mine fire fighting practices under similar spontaneous coal combustion conditions elsewhere. | YANG Shengqlang PANG Weidong WEN Hu YU Baohua MA Zhihe HUANG Ruiling | 2010 | Mining Science and Technology2010,20,5: | 1 |

| 10 | A genetically engineered Escherichia coli that senses and degrades tetracycline antibiotic residue显示文摘Due to the abuse of antibiotics,antibiotic residues can be detected in both natural environment and various industrial products,posing threat to the environment and human health.Here we describe the design and implementation of an engineered Escherichia coli capable of degrading tetracycline(Tc)-one of the commonly used antibiotics once on humans and now on poultry,cattle and fisheries.A Tcdegrading enzyme,TetX,from the obligate anaerobe Bacteroides fragilis was cloned and recombinantly expressed in E.coli and fully characterized,including its Km and kcat value.We quantitatively evaluated its activity both in vitro and in vivo by UVeVis spectrometer and LC-MS.Moreover,we used a tetracycline inducible amplification circuit including T7 RNA polymerase and its specific promoter PT7 to enhance the expression level of TetX,and studied the dose-response of TetX under different inducer concentrations.Since the deployment of genetically modified organisms(GMOs)outside laboratory brings about safety concerns,it is necessary to explore the possibility of integrating a kill-switch.Toxin-Antitoxin(TA)systems were used to construct a mutually dependent host-plasmid platform and biocontainment systems in various academic and industrious situations.We selected nine TA systems from various bacteria strains and measured the toxicity of toxins(T)and the detoxifying activity of cognate antitoxins(A)to validate their potential to be used to build a kill-switch.These results prove the possibility of using engineered microorganisms to tackle antibiotic residues in environment efficiently and safely. | Zepeng Mu Zhuoning Zou Ye Yang Wenbo Wang Yue Xu Jianyi Huang Ruiling Cai Ye Liu Yajin Mo Boyi Wang Yiqun Dang Yongming Li Yushan Liu Yueren Jiang Qingyang Tan Xiaohong Liu Cheng Hu Hua Li Sha Wei Chunbo Lou Yang Yu Jiangyun Wang | 2018 | Synthetic and Systems Biotechnology2018,3,3: | 0 |
| 11 | Regulation of excitation energy transfer in Sb-alloyed Cs_(4)MnBi_(2)Cl_(12) perovskites for efficient CO_(2) photoreduction to CO and water oxidation toward H_(2)O_(2)显示文摘Lead(Pb)-free halide perovskites have recently attracted increasing attention as potential catalysts for CO_(2) photoreduction to CO due to their potential to capture solar energy and drive catalytic reaction.However,issues of the poor charge transfer still remain one of the main obstacles limiting their performance due to the overwhelming radiative and nonradiative charge-carrier recombination losses.Herein,Pb-free Sb-alloyed all-inorganic quadruple perovskite Cs_(4)Mn(Bi_(1-x)Sb_(x))_(2)Cl_(12)(0≤x≤1)is synthesized as efficient photocatalyst.By Sb alloying,the undesired relaxation of photogenerated electrons from conduction band to emission centers of[MnCl6]^(4-)is greatly suppressed,resulting in a weakened PL emission and enhanced charge transfer for photocatalyst.The ensuing Cs_(4)Mn(Bi_(1-x)Sb_(x))_(2)Cl_(12) photocatalyst accomplishes efficient conversion of CO_(2)into CO,accompanied by a surprising production of H_(2)O_(2),a high valueadded product associated with water oxidation.By optimizing Sb^(3+) concentration,a high CO evolution rate of 35.1μmol g^(-1)h^(-1)is achieved,superior to most other Pb and Pb-free halide perovskites.Our findings provide new insights into the mixed-cation alloying strategies for improved photocatalytic performance of Pb-free perovskites and shed light on the rational design of robust band structure toward efficient energy transfer. | Haiwen Wei Zhen Li Honglei Wang Yang Yang Pengfei Cheng Peigeng Han Ruiling Zhang Feng Liu Panwang Zhou Keli Han | 2023 | Journal of Energy Chemistry2023,,7: | 0 |
| 12 | In situ rapid versatile method for the preparation of zirconium metal-organic framework filters显示文摘The development of the rapid preparation of highly stable metal-organic framework(MOF)-based devices provides the possibility of meeting the increasing demands of MOF in industrial applications.However,MOFs experience poor processability and stable high-valence-metal(Ⅳ)-based MOFs favor forming either thermodynamically stable metal hydroxides or oxides during their growth and nucleation,which hinders their practical applications.Herein,we present a versatile deep eutectic solvent(DES)-assisted hot pressing method to in situ rapidly prepare six distinct zirconium-based MOF nanocrystals on fibers(denoted as Zr-MOFilters)within 20 min.A small amount of DES promotes MOF precursor contact and accelerates Zr-MOF growth.Temperature and pressure facilitate the formation of Zr-MOFs onto desired substrates.In situ1H nuclear magnetic resonance spectra and time-dependent Fourier-transform infrared spectra were conducted to elucidate the growth of Zr-MOF nanocrystals.As a proof-of-concept,the abilities of Zr-MOFilters for Cr_(2)O_(7)^(2−) and micro(nano)plastics removal have been demonstrated.This strategy paves the way for the rapid fabrication of highly stable MOF-based devices and brings MOFs a step closer to practical application. | Hang Wang Xingmao Zhang Ruxin Yao Shuang Zhao Pengfei Zhao Ruile Yang Lin Wang Yichao Huang Tong Wei Xiang Li Zhuangjun Fan Bo Wang | 2022 | Science China Chemistry2022,65,12: | 0 |
| 13 | The role of a novel antibacterial substance,cyclic opine-producing Lacticaseibacillus rhamnosus LS8 in ameliorating ulcerative colitis:a fecal microbiota transplantation study显示文摘Intestinal microbiota imbalance may worsen the progression of ulcerative colitis(UC).Lacticaseibacillus rhamnosus LS8(LR)has the potential ability to regulate microbiota through producing a novel antibacterial substance,cyclic opine:cycloalanopine.This study aimed to investigate whether LR could ameliorate dextran sulfate sodium-induced UC in mice via modulating intestinal microbiota using fecal microbiota transplantation(FMT)experiment.The results showed that both LR and FMT attenuated UC as evidenced by 1)alleviating disease activity index and colonic pathology;2)up-regulating MUCs and tight junction proteins;3)increasing oxidative mediators and decreasing antioxidant mediators;4)down-regulating proinflammatory cytokines and chemokines.These results were mainly attributable to the microbiota-regulating effect of LR,including increasing beneficial bacteria(like Akkermansia)and its related SCFAs,while decreasing harmful bacteria(like Proteobacteria)and its related LPS,thereby suppressing the hyperactivation of TLR4/NF-κB pathway.Consequently,LR can alleviate UC and is a potential dietary supplement to attenuate UC. | Tao Wang Shuang Wang Shuchen Dong Ruiling Wang Shuxuan Wang Jie Yang Xin Wang Xin Lü | 2024 | Food Science and Human Wellness2024,13,2: | 0 |
| 14 | A new treatment for cognitive disorders related to in utero exposure to alcohol显示文摘Maternal alcohol consumption during pregnancy has detrimental effects on fetal central nervous system development. Maternal alcohol consumption prior to and during pregnancy significantly affects cognitive functions in offspring, which may be related to changes in cyclin-dependent kinase 5 because it is associated with modulation of synaptic plasticity and impaired learning and memory. In this study, we examined adult offspring in a maternal alcohol consumption model in rats. Y-maze test results showed that in utero exposure to alcohol impairs learning and memory capacities. Cyclin-dependent kinase 5 mRNA and protein expressions in the hippocampus of the offspring were significantly elevated, as assayed by quantitative real-time PCR and reverse transcription-PCR, immunofluorescence, and immuno-precipitation. Our experimental findings strongly suggest that altered cyclin-dependent kinase 5 may mediate impaired learning and memory in adult rats that were exposed to alcohol by maternal consumption while in utero. | Shuang Li Yan Zhang Feng Zhu Bin Zhang Jianying Lin Chunyang Xu Wancai Yang Wei Hao Ruiling Zhang | 2013 | Neural Regeneration Research2013,8,18: | 0 |
| 15 | Overexpression of MdFRK2 enhances apple drought resistance by promoting carbohydrate metabolism and root growth under drought stress显示文摘Soluble sugars function not only as the energy and structural blocks supporting plants,but also as osmoregulators and signal molecules during plant adaptation to water deficit.Here,we investigated drought resistance in transgenic apple(Malus×domestica)overexpressing MdFRK2,a key gene regulating fructose content and sugar metabolism.There is no obvious phenotypic difference between MdFRK2-overexpressing transgenic plants and WT plants under the well-watered condition.However,the transgenic plants and the grafted plants using MdFRK2-overexpressing rootstock exhibited improved tolerance to drought stress.Overexpression of MdFRK2 significantly promoted the growth of root system under drought stress.RNA sequencing showed that under drought stress,genes involved in sugar metabolism,transcription regulation,signal transduction or hormone metabolism were differentially expressed in MdFRK2 transgenic plants.Consistent with the gene expression profile,the activities of enzyme(SDH,FRK and NI)involved in sugar metabolism in the roots of MdFRK2 transgenic plants were significantly higher than those of untransformed control plants after drought stress.Under drought stress,overexpression of MdFRK2 promoted the accumulation of IAA,and decreased the contents of ABA and CK in apple root system.In conclusion,these results suggest that MdFRK2 can promote the growth of apple roots under drought stress by regulating sugar metabolism and accumulation,hormone metabolism and signal transduction,and then resist drought stress. | Jingjing Yang Ruiling Zhan Lan Wang Junqiao Li Baiquan Ma Fengwang Ma Mingjun Li | 2023 | Horticultural Plant Journal2023,9,5: | 0 |
| 16 | Tuning Exciton Recombination Pathways in Inorganic Bismuth-Based Perovskite for Broadband Emission显示文摘Single-component emitters with broadband emission are attractive but challenging for illumination and display applications.The two-dimensional organic-inorganic hybrid perovskites have exhibited outstanding broad emission property due to low electronic dimensionality and strong exciton-phonon coupling.However,few layered all-inorganic lead-free perovskites with broadband emission have been explored,and the explicit mechanism of exciton recombination in them also needs in-depth understanding.Herein,the inorganic bismuth-based perovskite Cs3Bi2Br9 achieves the stable broadband emission under ambient temperature and pressure by tuning the exciton recombination pathways via antimony(Sb)doping,and the photoluminescence quantum yield(PLQY)realizes an enhancement from 2.9%to 15.9%.The photoluminescence excitation(PLE)spectra indicate that the doped Sb introduces newly extrinsic self-trapped states.The incorporation of Sb promotes the transfer of free excitons(FEs)to extrinsic self-trapped excitons(STEs)observed from Sb content-dependent steady-state PL spectra and,meanwhile,reduces the nonradiative recombination of the generated extrinsic STEs,which are primarily responsible for the remarkably enhanced broad emission.Furthermore,femtosecond transient absorption results elucidate a clear exciton dynamics,in which the transition from FEs to STEs might arise through the gradient energy levels,and finally extrinsic STEs at various energy states contribute to the broadband emission. | Ming Shi Bin Yang Siping Liu Ruiling Zhang Keli Han Can Li Rengui Li | 2022 | Energy Material Advances2022,,1: | 0 |
