| 1 | Modern sedimentary environments and dynamic depositional systems in the southern Yellow Sea显示文摘Based on analyses of more than 600 surface sediment samples together with large amounts of previous sedimeutologic and hydrologic data, the characteristics of modern sedimentary environments and dynamic depositional systems in the southern Yellow Sea (SYS) are expounded, and the controversial formation mechanism of muddy sediments is also discussed. The southern Yellow Sea shelf can be divided into low-energy sedimentary environment and high-energy sedimentary environment; the lowenergy sedimentary environment can be further divided into cyclonic and anticyclonic ones, and the high-energy environment is subdivided into high-energy depositional and eroded environments. In the shelf low-energy environments,there developed muddy depositional system. In the central part of the southern Yellow Sea, there deposited the cold eddy sediments under the actions of a meso-scale cyclonic eddy (cold eddy), and in the southeast of the southern Yellow Sea, an anticyclonic eddy muddy depositional system (warm eddy sediment) was formed. These two types of sediments showed evident differences in grain size, sedimentation rate,sediment thickness and mineralogical characteristics. The high-energy environments were covered with sandy sediments on seabed; they appeared mainly in the west, south and northeast of the southern Yellow Sea. In the high-energy eroded environment, large amounts of sandstone gravels were distributed on seabed. In the high-energy depositional environment, the originally deposited fine materials (including clay and fine silt) were gradually re-suspended and then transported to a low-energy area to deposit again. In this paper, the sedimentation model of cyclonic and anticyclonic types of muddy sediments is established, and a systematic interpretation for the formation cause of muddy depositional systems in the southern Yellow Sea is given. | SHIXuefa SHENShunxi YIHi-il CHENZhihua MENGYi | 2003 | Chinese Science Bulletin2003,48,B06: | 13 |
| 2 | DAZL is a master translational regulator of murine spermatogenesis显示文摘Expression of DAZ-like(DAZL)is a hallmark of vertebrate germ cells,and is essential for embryonic germ cell development and differentiation,yet the gametogenic function of DAZL has not been fully characterized and most of its in vivo direct targets remain unknown.We showed that postnatal stage-specific deletion of Dazl in mouse germ cells did not affect female fertility,but caused complete male sterility with gradual loss of spermatogonial stem cells,meiotic arrest and spermatid arrest.Using the genome-wide high-throughput sequencing of RNAs isolated by cross-linking immunoprecipitation and mass spectrometry approach,we found that DAZL bound to a large number of testicular mRNA transcripts(at least 3008)at the 3′-untranslated region and interacted with translation proteins including poly(A)binding protein.In the absence of DAZL,polysome-associated target transcripts,but not their total transcripts,were significantly decreased,resulting in a drastic reduction of an array of spermatogenic proteins and thus developmental arrest.Thus,DAZL is a master translational regulator essential for spermatogenesis. | Haixin Li Zhuqing Liang Jian Yang Dan Wang Hanben Wang Mengyi Zhu Baobao Geng Eugene Yujun Xu | 2019 | National Science Review2019,6,3: | 11 |
| 3 | Suspended particulate matter in Jiaozhou Bay:Properties and variations in response to hydrodynamics and pollution显示文摘Based on water samples collected and observations of currents, tidal levels as well as turbidities taken, respectively over a period of 15 and 7 d, in southwestern Jiaozhou Bay on August, 2001, it was found that: ( i ) the average content of non mineral component amounted to 87% of the suspended sediment matter (SPM) in Jiaozhou Bay,much higher than in estuaries and bays where turbidity is high and mineral particulates dominates; (ii) in contrast to high turbid bays, SPM was generally coarser than bed deposits and in upper water column than in lower water column in Jiaozhou Bay; (iii) in fair weathers, suspended sediment concentration (SPC) varied regularly within tidal cycles and neap-spring cycles, but the regularity was deformed in storms; and (iv) SPC was controlled by settling/resuspension near the bed and by advection at the surface at the study site with a depth of 20 m, suggesting weak vertical exchanges. It was concluded that SPM property of a low turbid bay is sensitive to pollution, and that the maintenance of low turbidity in the bay depends on less SPM supply, low waves and currents, and controlling on discharge of particulate pollutants. | YANGShilun MENGYi ZHANGJing XUEYuanzhong CHENHongtao WEIHao LIUZhe WURuiming WANGLingxiang YANGHua WANGLiang ZHANGWenxiang | 2004 | Chinese Science Bulletin2004,49,1: | 8 |

| 5 | Automatic analytical approach for the determination of 12 illicit drugs and nicotine metabolites in wastewater using on-line SPE-UHPLC-MS/MS显示文摘In this study,we developed a novel on-line solid phase extraction(SPE)-ultra-high-performance liquid chromatography tandem mass spectrometry(UHPLC-MS/MS)-based analytical method for simultaneously quantifying 12 illicit drugs and metabolites(methamphetamine,amphetamine,morphine,codeine,6-monoacetylmorphine,benzoylecgonine,3,4-methylenedioxymethamphetamine,3,4-methylenedioxyamphetamine,cocaine,ketamine,norketamine,and methcathinone)and cotinine(COT)in wastewater samples.The analysis was performed by loading 2 m L of the sample onto an Oasis hydrophilic-lipophilic balance cartridge and using a cleanup step(5%methanol)to eliminate interference with a total run time of 13 min.The isotope-labeled internal standard method was used to quantify the target substances and correct for unavoidable losses and matrix effects during the on-line SPE process.Typical analytical characteristics used for method validation were sensitivity,linearity,precision,repeatability,recovery,and matrix effects.The limit of detection(LOD)and limit of quantification(LOQ)of each target were set at 0.20 ng/L and 0.50 ng/L,respectively.The linearity was between 0.5 ng/L and250 ng/L,except for that of COT.The intra-and inter-day precisions were<10.45%and 25.64%,respectively,and the relative recovery ranged from 83.74%to 162.26%.The method was used to analyze various wastewater samples from 33 cities in China,and the results were compared with the experimental results of identical samples analyzed using off-line SPE.The difference rate was between 19.91%and-20.44%,and the error range could be considered acceptable.These findings showed that on-line SPE is a suitable alternative to off-line SPE for the analysis of illicit drugs in samples. | Jingyuan Wang Likai Qia Chenzhi Hou Tingting Zhang Mengyi Chen Haitao Meng Mengxiang Su Hui Xu Zhendong Hua Youmei Wang Bin Di | 2021 | Journal of Pharmaceutical Analysis2021,11,6: | 5 |

| 8 | A biomass carbon material with microtubule bundling and natural O-doping derived from goldenberry calyx and its electrochemical performance in supercapacitor显示文摘A promising biomass carbon material,manufactured by the carbonation of Physalis peruviana L.calyx at 700℃,is presented in this wo rk.Morphology characterization shows that the carbon material possesses long microtubule bundling and above 30%natural O-atom component on the surface.After KOH chemical etching,the materials maintain the oxygen content but exhibit more micropores and higher specific surface area up to 1732.6 m^2/g.Using as an electrode material for supercapacitor,the active carbon material exhibits high specific capacitance up to 339.7 F/g at 0.5 A/g in 3 mol/L KOH aqueous solution through three-electrode system.The active carbon material also exhibits excellent cycling stability(97%retention)by 10,000 cycles at 10 A/g.The outstanding electrochemical performances are attributing to the unique long microtubule bundling with much more pores and the abundant Oelement on the surface.This biomass carbon material with excellent electrochemical properties could be a useful material for multiple applications. | Yang Liu Mengyi Zhang Liqiu Wang Yajuan Hou Chenxiao Guo Haiying Xin Shuang Xu | 2020 | Chinese Chemical Letters2020,31,3: | 4 |
| 9 | Development and validation of a CT-based radiomics nomogram for preoperative prediction of tumor histologic grade in gastric adenocarcinoma显示文摘Objectives:To develop and validate a radiomics nomogram for preoperative prediction of tumor histologic grade in gastric adenocarcinoma(GA).Methods:This retrospective study enrolled 592 patients with clinicopathologically confirmed GA(low-grade:n=154;high-grade:n=438)from January 2008 to March 2018 who were divided into training(n=450)and validation(n=142)sets according to the time of computed tomography(CT)examination.Radiomic features were extracted from the portal venous phase CT images.The Mann-Whitney U test and the least absolute shrinkage and selection operator(LASSO)regression model were used for feature selection,data dimension reduction and radiomics signature construction.Multivariable logistic regression analysis was applied to develop the prediction model.The radiomics signature and independent clinicopathologic risk factors were incorporated and presented as a radiomics nomogram.The performance of the nomogram was assessed with respect to its calibration and discrimination.Results:A radiomics signature containing 12 selected features was significantly associated with the histologic grade of GA(P<0.001 for both training and validation sets).A nomogram including the radiomics signature and tumor location as predictors was developed.The model showed both good calibration and good discrimination,in which C-index in the training set,0.752[95%confidence interval(95%CI):0.701-0.803];C-index in the validation set,0.793(95%CI:0.711-0.874).Conclusions:This study developed a radiomics nomogram that incorporates tumor location and radiomics signatures,which can be useful in facilitating preoperative individualized prediction of histologic grade of GA. | Jia Huang Huasheng Yao Yexing Li Mengyi Dong Chu Han Lan He Xiaomei Huang Ting Xia Zongjian Yi Huihui Wang Yuan Zhang Jian He Changhong Liang Zaiyi Liu | 2021 | Chinese Journal of Cancer Research2021,33,1: | 3 |
| 10 | Machine learning helps improve diagnostic ability of subclinical keratoconus using Scheimpflug and OCT imaging modalities显示文摘Purpose:To develop an automated classification system using a machine learning classifier to distinguish clinically unaffected eyes in patients with keratoconus from a normal control population based on a combination of Scheimpflug camera images and ultra-high-resolution optical coherence tomography(UHR-OCT)imaging data.Methods:A total of 121 eyes from 121 participants were classified by 2 cornea experts into 3 groups:normal(50 eyes),with keratoconus(38 eyes)or with subclinical keratoconus(33 eyes).All eyes were imaged with a Scheimpflug camera and UHR-OCT.Corneal morphological features were extracted from the imaging data.A neural network was used to train a model based on these features to distinguish the eyes with subclinical keratoconus from normal eyes.Fisher’s score was used to rank the differentiable power of each feature.The receiver operating characteristic(ROC)curves were calculated to obtain the area under the ROC curves(AUCs).Results:The developed classification model used to combine all features from the Scheimpflug camera and UHR-OCT dramatically improved the differentiable power to discriminate between normal eyes and eyes with subclinical keratoconus(AUC=0.93).The variation in the thickness profile within each individual in the corneal epithelium extracted from UHR-OCT imaging ranked the highest in differentiating eyes with subclinical keratoconus from normal eyes.Conclusion:The automated classification system using machine learning based on the combination of Scheimpflug camera data and UHR-OCT imaging data showed excellent performance in discriminating eyes with subclinical keratoconus from normal eyes.The epithelial features extracted from the OCT images were the most valuable in the discrimination process.This classification system has the potential to improve the differentiable power of subclinical keratoconus and the efficiency of keratoconus screening. | Ce Shi Mengyi Wang Tiantian Zhu Ying Zhang Yufeng Ye Jun Jiang Sisi Chen Fan Lu Meixiao Shen | 2020 | Eye and Vision2020,7,1: | 3 |

| 12 | The creep compaction behavior of crushed mudstones under the step loading in underground mining显示文摘The crushed rocks are used as a filling material in mined丒out areas of underground mining. Compared with the man-made filling materials, the crushed rocks exhibit higher compressibility and lower stability, which may result in instability of surrounding rock and surface subsidence. To study the creep compaction behavior of crushed mudstones, a series of creep tests are conducted. The investigations show that the creep compaction behavior of crushed mudstones is highly dependent on the original grain composition and axial stress applied on the samples. The samples with more large particles are easier to deform at initial loading stage for more large voids existed in the samples, and exhibit greater stability than those with smaller particles when the axial stress less than the bearing capacity of uframework structure When the axial stress is higher than 20 MPa, the influences of grain composition on deformability of crushed mudstones are weakened after the samples experience repeated compression. At lower stress level, the creep behavior prefers to occur in the samples w.h smaller particles, which is mainly caused by particles flow without significant particle breakage. As the axial stress increases, the single-sized sample with smaller particle size and the well-graded sample with larger Talbol power exponent n present more unstable under the constant stress. In addition, the filling of the residual intergranular voids by small particles formed by crushing and splitting behavior is the main cause of creep deformation. Lastly, a creep equation of crushed mudstones is obtained in this paper, which can agree with the experimental results in good. | Zhibiao Guo Qiong Wang Songyang Yin Xiaohui Kuai Dongshan Yan Mengyi Li Yandong Qu | 2019 | International Journal of Coal Science & Technology2019,6,3: | 2 |
| 13 | Quantitative prediction process and evaluation method for seafloor polymetallic sulfide resources显示文摘Seafloor polymetallic sulfide resources exhibit significant development potential.In 2011,China received the exploration rights for 10,000 km^2 of a polymetallic sulfides area in the Southwest Indian Ocean;China will be permitted to retain only 25%of the area in 2021.However,an exploration of seafloor hydrothermal sulfide deposits in China remains in the initial stage.According to the quantitative prediction theory and the exploration status of seafloor sulfides,this paper systematically proposes a quantitative prediction evaluation process of oceanic polymetallic sulfide resources and divides it into three stages:prediction in a large area,prediction in the prospecting region,and the verification and evaluation of targets.The first two stages of the prediction process have been employed in seafloor sulfides prospecting of the Chinese contract area.The results of stage one suggest that the Chinese contract area is located in the high posterior probability area,which indicates good prospecting potential area in the Indian Ocean.In stage two,the Chinese contract area of 48°-52° E has the highest posterior probability value,which can be selected as the reserved region for additional exploration.In stage three,the method of numerical simulation is employed to reproduce the ore-forming process of sulfides to verify the accuracy of the reserved targets obtained from the three-stage prediction.By narrowing the exploration area and gradually improving the exploration accuracy,the prediction will provide a basis for the exploration and exploitation of seafloor polymetallic sulfide resources. | Mengyi Ren Jianping Chen Ke Shao Miao Yu Jie Fang | 2016 | Geoscience Frontiers2016,7,2: | 2 |
| 14 | Balancing sub‐reaction activity to boost electrocatalytic urea synthesis using a metal‐free electrocatalyst显示文摘Electrocatalytic urea synthesis via coupling of nitrate with CO_(2)is considered as a promising alternative to the industrial urea synthetic process.However,the requirement of sub-reaction(NO_(3)RR and CO_(2)RR)activities for efficient urea synthesis is not clear and the related reaction mechanisms remain obscure.Here,the construction,breaking,and rebuilding of the sub-reaction activity balance would be accompanied by the corresponding regulation in urea synthesis,and the balance of sub-reaction activities was proven to play a vital role in efficient urea synthesis.With rational design,a urea yield rate of 610.6 mg h−1 gcat.−1 was realized on the N-doped carbon electrocatalyst,superior to that of noble-metal electrocatalysts.Based on the operando SRFTIR measurements,we proposed that urea synthesis arises from the coupling of^(*)NO and^(*)CO to generate the key intermediate of^(*)OCNO.This work provides new insights and guidelines into urea synthesis from the aspect of activity balance. | Chen Chen Shuang Li Xiaorong Zhu Shuowen Bo Kai Cheng Nihan He Mengyi Qiu Chao Xie Dezhong Song Youzhen Liu Wei Chen Yafei Li Qinghua Liu Conggang Li Shuangyin Wang | 2023 | Carbon Energy2023,5,10: | 2 |
| 15 | 3D-assembled microneedle ion sensor-based wearable system for the transdermal monitoring of physiological ion fluctuations显示文摘Monitoring human health is of considerable significance in biomedicine.In particular,the ion concentrations in blood are important reference indicators related to many diseases.Microneedle array-based sensors have enabled promising breakthroughs in continuous health monitoring due to their minimally invasive nature.In this study,we developed a microneedle sensing-array integrated system to continuously detect subcutaneous ions to monitor human health status in real time based on a fabrication strategy for assembling planar microneedle sheets to form 3D microneedle arrays.The limitations of preparing 3D microneedle structures with multiple electrode channels were addressed by assembling planar microneedle sheets fabricated via laser micromachining;the challenges of modifying closely spaced microneedle tips into different functionalized types of electrodes were avoided.The microneedle sensing system was sufficiently sensitive for detecting real-time changes in Ca^(2+),K^(+),and Na^(+) concentrations,and it exhibited good detection performance.The in vivo results showed that the ion-sensing microneedle array successfully monitored the fluctuations in Ca^(2+),k^(+),and Na^(+) in the interstitial fluids of rats in real time.By using an integrated circuit design,we constructed the proposed microneedle sensor into a wearable integrated monitoring system.The integrated system could potentially provide information feedback for diseases related to physiological ion changes. | Xinshuo Huang Shantao Zheng Baoming Liang Mengyi He Feifei Wu Jingbo Yang Hui-jiuan Chen Xi Xie | 2023 | Microsystems & Nanoengineering2023,9,2: | 2 |

| 18 | Theoretical Study on the Structures,Spectral Properties,and Drugability of Xenicane-type Diterpenoids from Dictyota dichotoma显示文摘There are few reports on the relationship between the biological activity and structure of secondary metabolites from Dictyota dichotoma. In this work, the geometric and electronic structures, infrared spectra, ultraviolet spectra, 13C and 1H NMR spectra of 16 xenicane-type diterpenoids extracted from Dictyota dichotoma were studied by the density functional theory ωB97XD/6-311+G(2d,p) method. The analysis of the reactivity indices was carried out via the conceptual density functional theory. Furthermore, a pharmacodynamic evaluation was performed using ADME/Tox. The geometric structure analysis found that all 16 diterpenoids had the same unsaturated, branched chains and could be divided into two categories according to the ring size, including nine-membered and eight-membered rings. A hydroxyl group on the lactone ring reduced the stability of the compound. In contrast, a hydroxyl group on the parent ring had little effect on the compound's stability. The electrostatic potential results preliminarily predicted active sites for nucleophilic/electrophilic reactions. The fitting results of infrared and nuclear magnetic resonance(NMR) data showed that the theoretical values obtained by this method were consistent with the experimental values. The UV-visible absorption spectra showed that the solvent effects caused different redshifts of the absorption peaks. The absorption strength was enhanced. The sixteen diterpenoids displayed a strong absorption peak in the range of 180―200 nm, but the compound containing a carbonyl group presents a weaker absorption peak in the field of 200―240 nm. Compounds 9―11, 14, and 15 have better stability and reactivity with lower chemical potentials and higher electronegativity, electrophilic index, and hardness values. The local reactivity descriptors further identified nucleophilic/electrophilic reaction sites for the sixteen compounds. Finally, the pharmacodynamic evaluation results predicted that compounds 2, 4, 8, 11, and 14―16 have optimal drugability. The theoretical results of this work may provide a rich data information for the other experimental study on the cembrane diterpenoids in medicine. | HUANG Luoyi SUN Xiang CHEN Mengyi YAN Pengcheng WANG Chaojie | 2022 | Chemical Research in Chinese Universities2022,38,2: | 1 |
| 19 | Generation and functional characterization of a conditional Pumilio2 null allele显示文摘The highly conserved RNA binding protein PUF(Pumilio/FBF) family is present throughout eukaryotes from yeast to mammals, with critical roles in development, fertility and the nervous system. However, the function of the mammalian PUF family members remains underexplored. Our previous study reported that a gene-trap mutation of Purm2 results in a smaller testis but does not impact fertility and viability. Although the gene-trap mutation disrupted the key functional domain of PUM protein-PUM-HD(Pumilio homology domain), but still produced a chimeric Pum2-β-geo protein containing part of PUM2, raising a question if such a chimeric protein may provide any residual function or contribute to the reproductive phenotype. Here, we report the generation of a conditional PUM2 allele,when knocked out, producing no residual PUM2 and hence a complete loss-of-function allele. We also uncovered small but significant reduction of male fertility and viability in the mutants, suggesting requirement of PUM2 for male fertility and viability. | Kaibo Lin Shikun Zhang Jieli Chen Ding Yang Mengyi Zhu Eugene Yujun Xu | 2018 | The Journal of Biomedical Research2018,32,6: | 1 |
