| 1 | The linkage maps of Dendrobium species based on RAPD and SRAP markers显示文摘Dendrobium plants are used commonly as tonic herbs and health food in many Asian countries,especially in China.Here we report the genetic map construction of two Dendrobium species with a double pseudo-testcross strategy using random amplified polymorphic DNA(RAPD) and sequence-related amplified polymorphism(SRAP) markers.A F1 mapping population of 90 individuals was developed from a cross between D.officinale and D.hercoglossum.A total of 307 markers,including 209 RAPD and 98 SRAP,were identified and used for genetic linkage group(LG) analysis.The D.officinale linkage map consisted of 11 major linkage groups and 3 doublets,which covered 629.4 cM by a total of 62 markers with an average locus distance of 11.2 cM between two adjacent markers.The D.hercoglossum linkage map contained 112 markers mapped on 15 major and 4 minor linkage groups,spanning a total length of 1,304.6 cM with an average distance of 11.6 cM between two adjacent markers.The maps constructed in this study covered 92.7% and 82.7% of the D.hercoglossum and D.officinale genomes respectively,providing an important basis for the mapping of horticultural and medicinal traits and for the application of marker-assisted selection in Dendrobium breeding program. | Dawei Xue Shangguo Feng Hongyan Zhao Hua Jiang Bo Shen Nongnong Shi Jiangjie Lu Junjun Liu Huizhong Wang | 2010 | Journal of Genetics and Genomics2010，37，3： | 26 |
| 2 | Experimental and numerical study of failure behavior and mechanism of coal under dynamic compressive loads显示文摘A comprehensive understanding of the failure behavior and mechanism of coal is a prerequisite for dealing with dynamic problems in mining space.In this study,the failure behavior and mechanism of coal under uniaxial dynamic compressive loads were experimentally and numerically investigated.The experiments were conducted using a split Hopkinson pressure bar(SHPB)system.The results indicated that the typical failure of coal is lateral and axial at lower loading rates and totally smashed at higher loading rates.The further fractography analysis of lateral and axial fracture fragments indicated that the coal failure under dynamic compressive load is caused by tensile brittle fracture.In addition,the typical failure modes of coal under dynamic load were numerically reproduced.The numerical results indicated that the axial fracture is caused directly by the incident compressive stress wave and the lateral fracture is caused by the tensile stress wave reflected from the interface between coal specimen and transmitted bar.Potential application was further conducted to interpret dynamic problems in underground coal mine and it manifested that the lateral and axial fractures of coal constitute the parallel cracks in the coal mass under roof fall and blasting in mining space. | Junjun Feng Enyuan Wang Qisong Huang Houcheng Ding Xiangyang Zhang | 2020 | International Journal of Mining Science and Technology2020，30，5： | 13 |
| 3 | Energy dissipation rate: An indicator of coal deformation and failure under static and dynamic compressive loads显示文摘Dynamic disasters in Chinese coal mines pose a significant threat to coal productivity. Thus, a thorough understanding of the deformation and failure processes of coal is necessary. In this study, the energy dissipation rate is proposed as a novel indicator of coal deformation and failure under static and dynamic compressive loads. The relationship between stress-strain, uniaxial compressive strength, displacement rate, loading rate, fractal dimension, and energy dissipation rate was investigated through experiments conducted using the MTS C60 tests(static loads) and split Hopkinson pressure bar system(dynamic loads). The results show that the energy dissipation rate peaks are associated with stress drop during coal deformation, and also positively related to the uniaxial compressive strength. A higher displacement rate of quasi-static loads leads to an initial increase and then a decrease in energy dissipation rate, whereas a higher loading rate of dynamic loads results in larger energy dissipation rate. Theoretical analysis indicates that a sudden increase in energy dissipation rate suggests partial fracture occurring within coal under both quasi-static and dynamic loads. Hence, the energy dissipation rate is an essential indicator of partial fracture and final failure within coal, as well as a prospective precursor for catastrophic failure in coal mine. | Feng Junjun Wang Enyuan Chen Xia Ding Houcheng | 2018 | International Journal of Mining Science and Technology2018，28，3： | 12 |
| 4 | BMP-IHH-mediated interplay between mesenchymal stem cells and osteoclasts supports calvarial bone homeostasis and repair显示文摘Calvarial bones are connected by fibrous sutures. These sutures provide a niche environment that includes mesenchymal stem cells(MSCs), osteoblasts, and osteoclasts, which help maintain calvarial bone homeostasis and repair. Abnormal function of osteogenic cells or diminished MSCs within the cranial suture can lead to skull defects, such as craniosynostosis. Despite the important function of each of these cell types within the cranial suture, we have limited knowledge about the role that crosstalk between them may play in regulating calvarial bone homeostasis and injury repair. Here we show that suture MSCs give rise to osteoprogenitors that show active bone morphogenetic protein(BMP) signalling and depend on BMP-mediated Indian hedgehog(IHH) signalling to balance osteogenesis and osteoclastogenesis activity. IHH signalling and receptor activator of nuclear factor kappa-Β ligand(RANKL) may function synergistically to promote the differentiation and resorption activity of osteoclasts. Loss of Bmpr1a in MSCs leads to downregulation of hedgehog(Hh) signalling and diminished cranial sutures. Significantly, activation of Hh signalling partially restores suture morphology in Bmpr1a mutant mice, suggesting the functional importance of BMP-mediated Hh signalling in regulating suture tissue homeostasis. Furthermore, there is an increased number of CD200+ cells in Bmpr1a mutant mice, which may also contribute to the inhibited osteoclast activity in the sutures of mutant mice. Finally, suture MSCs require BMPmediated Hh signalling during the repair of calvarial bone defects after injury. Collectively, our studies reveal the molecular and cellular mechanisms governing cell–cell interactions within the cranial suture that regulate calvarial bone homeostasis and repair. | Yuxing Guo Yuan Yuan Ling Wu Thach-Vu Ho Junjun Jing Hideki Sugii Jingyuan Li Xia Han Jifan Feng Chuanbin Guo Yang Chai | 2018 | Bone Research2018，6，4： | 12 |
| 5 | Single-center Experience in the Diagnosis and Treatment of Hepatic Perivascular Epithelioid Cell Neoplasm显示文摘Background and Aims:Perivascular epithelioid cell neo-plasms(PEComas)are a rare type of mesenchymal neo-plasm and their preoperative diagnosis is challenging.In this study,we summarized the experience from a single medical center to study the examinations,clinical presen-tations,and pathological and histological characteristics of PEComas in the liver in order to optimize overall un-derstanding of the diagnosis and treatment of these neo-plasms.Methods:We conducted a retrospective analysis to investigate the clinical and pathological characteristics as well as imaging presentations of 75 patients diagnosed with hepatic PEComa in The First Affiliated Hospital of Zhe-jiang University between April 2010 and April 2020.Re-sults:Among the 75 patients,52 were women,and the median age was 48 years.Most patients had no specific symptoms,and two were admitted to the hospital for a second time owing to relapse.All patients underwent surgi-cal resection.Histologically,38 patients had classical angio-myolipoma(AML)and 37 had epithelioid AML.The PECo-mas were accompanied by positive immunohistochemical expression of HMB45,Melan-A,and smooth muscle actin.Follow-up data were obtained from 47 of the total 75 pa-tients,through October 2020.Two patients had metastasis after surgery.Conclusions:AML is the most common type of hepatic PEComa.There are no specific symptoms of he-patic PEComa,and serological examinations and imaging modalities for accurate preoperative diagnosis are lacking.Epithelioid AML should be considered a tumor of uncertain malignant potential;however,the prognosis of PEComa af-ter resection is promising. | Junjun Jia Jia Luo Cheng-Gen Pan Guomei Ge Meibao Feng Bei Zou Li Liu Shusen Zheng Jun Yu | 2022 | Journal of Clinical and Translational Hepatology2022，10，1： | 5 |
| 6 | Natural variations of ZmSRO1d modulate the trade-off between drought resistance and yield by affecting ZmRBOHC-mediated stomatal ROS production in maize显示文摘While crop yields have historically increased,drought resistance has become a major concern in the context of global climate change.The trade-off between crop yield and drought resistance is a common phenomenon;however,the underlying molecular modulators remain undetermined.Through genome-wide association study,we revealed that three non-synonymous variants in a drought-resistant allele of ZmSRO1d-R resulted in plasma membrane localization and enhanced mono-ADP-ribosyltransferase activity of ZmSRO1d toward ZmRBOHC,which increased reactive oxygen species(ROS)levels in guard cells and promoted stomatal closure.ZmSRO1d-R enhanced plant drought resilience and protected grain yields under drought conditions,but it led to yield drag under favorable conditions.In contrast,loss-of-function mutants of ZmRBOHC showed remarkably increased yields under well-watered conditions,whereas they showed compromised drought resistance.Interestingly,by analyzing 189 teosinte accessions,we found that the ZmSRO1d-R allele was present in teosinte but was selected against during maize domestication and modern breeding.Collectively,our work suggests that the allele frequency reduction of ZmSRO1d-R in breeding programs may have compromised maize drought resistance while increased yields.Therefore,introduction of the ZmSRO1d-R allele into modern maize cultivars would contribute to food security under drought stress caused by global climate change. | Huajian Gao Junjun Cui Shengxue Liu Shuhui Wang Yongyan Lian Yunting Bai Tengfei Zhu Haohao Wu Yijie Wang Shiping Yang Xuefeng Li Junhong Zhuang Limei Chen Zhizhong Gong Feng Qin | 2022 | Molecular Plant2022，15，10： | 2 |
| 7 | Reconfigurable photovoltaic effect for optoelectronic artificial synapse based on ferroelectric p-n junction显示文摘Neuromorphic machine vision has attracted extensive attention on wide fields.However,both current and emerging strategies still suffer from power/time inefficiency,and/or low compatibility,complex device structure.Here we demonstrate a driving-voltage-free optoelectronic synaptic device using non-volatile reconfigurable photovoltaic effect based on MoTe_(2)/α-In_(2)Se_(3) ferroelectric p-n junctions.This function comes from the non-volatile reconfigurable built-in potential in the p-n junction that is related to the ferroelectric polarization inα-In_(2)Se_(3).Reconfigurable rectification behavior and photovoltaic effect are demonstrated firstly.Notably,the figure-of-merits for photovoltaic effect like photoelectrical conversion efficiency non-volatilely increases more than one order.Based on this,retina synapse-like vision functions are mimicked.Optoelectronic short-term and long-term plasticity,as well as basic neuromorphic learning and memory rule are achieved without applying driving voltage.Our work highlights the potential of ferroelectric p-n junctions for enhanced solar cell and low-power optoelectronic synaptic device for neuromorphic machine vision. | Yanrong Wang Feng Wang Zhenxing Wang Junjun Wang Jia Yang Yuyu Yao Ningning Li Marshet Getaye Sendeku Xueying Zhan Congxin Shan Jun He | 2021 | Nano Research2021，14，11： | 2 |

| 9 | Mapping Soil Organic Carbon Stocks of Northeastern China Using Expert Knowledge and GIS-based Methods显示文摘The main aim of this paper was to calculate soil organic carbon stock(SOCS) with consideration of the pedogenetic horizons using expert knowledge and GIS-based methods in northeastern China.A novel prediction process was presented and was referred to as model-then-calculate with respect to the variable thicknesses of soil horizons(MCV).The model-then-calculate with fixed-thickness(MCF),soil profile statistics(SPS),pedological professional knowledge-based(PKB) and vegetation type-based(Veg) methods were carried out for comparison.With respect to the similar pedological information,nine common layers from topsoil to bedrock were grouped in the MCV.Validation results suggested that the MCV method generated better performance than the other methods considered.For the comparison of polygon based approaches,the Veg method generated better accuracy than both SPS and PKB,as limited soil data were incorporated.Additional prediction of the pedogenetic horizons within MCV benefitted the regional SOCS estimation and provided information for future soil classification and understanding of soil functions.The intermediate product,that is,horizon thickness maps were fluctuant enough and reflected many details in space.The linear mixed model indicated that mean annual air temperature(MAAT) was the most important predictor for the SOCS simulation.The minimal residual of the linear mixed models was achieved in the vegetation type-based model,whereas the maximal residual was fitted in the soil type-based model.About 95% of SOCS could be found in Argosols,Cambosols and Isohumosols.The largest SOCS was found in the croplands with vegetation of Triticum aestivum L.,Sorghum bicolor(L.) Moench,Glycine max(L.) Merr.,Zea mays L.and Setaria italica(L.)

| 13 | Effect of semi-continuous water washing on the combustion behaviors of agricultural organic solid waste显示文摘Combustion of agricultural organic solid waste(AOSW)was an ideal solution for their resource utilization in view of their massive annual production and great potential for reduction of fossil fuel utilization.However,high alkali and alkaline earth metals(AAEMs)content in the feedstock can arose severe fouling and slagging issues and thus prohibiting its vast utilization.In this study,a semi-continuous water washing method was proposed to preliminarily remove AAEMs from agricultural organic solid waste and its effects on the combustion behaviors of washed solid product were investigated.Results showed that the combustion index S were improved to 2.63×10-6,over 68%of the total ashes were removed from the cotton stalk,and 96.3%,89.0%and 74.7%of K,Na and Mg were effectively removed,respectively.Moreover,the softening temperature of low temperature ash from the washed sample was as high as 1450◦C,538◦C higher than the low temperature ash from the original sample;the base acid ratio and fouling index were improved from high slagging and fouling risk(1.7 and 90.8)of the original organic solid waste to low and medium risk(0.4 and 3.5),respectively.All these results signified the contributing effect of proposed semi-continuous water washing method on the combustion of agricultural organic solid waste.In a word,this study provided a promising method for fouling and slagging inhibition during the agricultural organic solid waste combustion. | Xiangxi Wang Zhenzhong Hu Jinrong Ma Linlin Yi Jian Li Yanfeng Cheng Jianfei Ma Na An Feng Wang Xian Li Junjun Yan Bo Wei Yue Li Guangqian Luo Hong Yao | 2023 | Carbon Resources Conversion2023，6，1： | 0 |
| 14 | Digestion performance improvement of tributyrin through nano-emulsion preparation technology显示文摘The current research aimed to optimize the preparation technology of tributyrin nano-emulsion(TBNE)to improve its digestion properties, which were investigated through digestion models in vitro and in vivo. The content of each component of TBNE was optimized by response surface methodology(RSM) to improve the z-average particle size and stability of TBNE. The optimized TBNE was evaluated for its digestion properties by in vitro and in vivo models. The preparation conditions of TBNE optimized by RSM were as follows: 61.3% of sorbitol, 32.7% of tributyrin, and 6.0% of modified phospholipid(MP). The predicted z-average particle size of TBNE was(246.02 ± 18.10) nm. The results of the verification test showed that the z-average particle size, zeta potential, conductivity, emulsification activity index, and emulsification stability index of TBNE were(250.02 ± 7.18) nm,(-40.23 ± 0.76) m V,(31.80 ± 2.09) μS/cm,(848.00 ± 84.53) min and(1.14 ± 0.02) m^(2)/g, respectively. The in vitro digestion experiment results showed that the TBNE remained stable in the stomach and was released in the intestine, while the size of TBNE in the gastrointestinal tact was significantly smaller than that of tributyrin(P < 0.05), which made it easier to be digested and absorbed. Compared with tributyrin treatment, TBNE significantly promoted the average body weight at the 7th day, average daily feed intake,average daily gain, feed/gain, ileum weight, and organ index of ileum of Hy-Line BROWN chicks(P < 0.05), and the butyric acid content in the ileal chyme from TBNE and tributyrin treatment were172.18 mg/m L and 100.85 mg/m L(P < 0.01). Therefore, the established TBNE technology in this study could be supposed to improve the digestion properties of tributyrin. | Feng Gao Yaoming Cui Shijia Song Jinfeng Zhu Xinyu Liu Xuyang Ji Hao Zhu Qingyu Jia Qiaohan Lin Junjun Guan | 2022 | Grain & Oil Science and Technology2022，5，3： | 0 |
| 15 | Effects of vermiculite on the growth process of submerged macrophyte Vallisneria spiralis and sediment microecological environment显示文摘Ecological restoration is one of the hot technologies for the reconstruction of eutrophic lake ecosystems in which the restoration and propagation of submerged plants is the key and difficult step. In this paper, the effect of vermiculite on the growth process of Vallisneria spiralis and sediment microenvironment were investigated, aiming to provide a theoretical basis for the application of vermiculite in aquatic ecological restoration. Results of growth indexes demonstrated that 5% and 10% vermiculite treatment groups statistically promote the growth of Vallisneria spiralis compared to the control. Meanwhile, the results of ecophysiological indexes showed that photosynthetic pigment, soluble sugar content, superoxide dismutase(SOD), and catalase(CAT) activity of 5% and 10% group were increased compared with the control while the malondialdehyde(MDA) content exhibited the opposite result(p < 0.05), which illustrated that vermiculite can improve the resistance of plants and delay the aging process of Vallisneria spiralis. In addition, result of PCA(Principal Component Analysis) demonstrated 5% and 10% group has improved the sediment physical conditions and create more ecological niche for microorganisms directly, and then promoted the growth of plants. The dissolution results showed that vermiculite can dissolve the constant and trace elements needed for plant growth. Furthermore, the addition of vermiculite increased the diversity of microorganisms in the sediments, and promoted the increase of plant growth-promoting bacteria and phosphorus-degrading bacteria. This study could provide a technique reference for the further application of vermiculite in the field of ecological restoration. | Guoliang Bai Feng Luo Yilingyun Zou Yunli Liu Rou Wang Hang Yang Zisen Liu Junjun Chang Zhenbin Wu Yi Zhang | 2022 | Journal of Environmental Sciences2022，34，8： | 0 |
| 16 | Copper-induced formation of heterostructured Co_(3)O_(4)/CuO hollow nanospheres towards greatly enhanced lithium storage performance显示文摘We report a facile template-free fabrication of heterostructured Co_(3)O_(4)/CuO hollow nanospheres using pre-synthesized Co/Cu-glycerate as conformal precursor.The introduction of copper nitrate in the solvothermal reaction system of glycerol/isopropanol/cobalt nitrate readily induces the conversion from solid Co-glycerate to hollow Co/Cu-glycerate nanospheres,and the effect of the Co/Cu atomic ratio on the structure evolution of the metal glycerates as well as their corresponding oxides were investigated.When examined as anode materials for lithium-ion batteries,the well-defined Co_(3)O_(4)/CuO hollow nanospheres with Co/Cu molar ratio of 2.0 demonstrate excellent lithium storage performance,delivering a high reversible capacity of 930 mAh/g after 300 cycles at a current density of 0.5 A/g and a stable capacity of 650 mAh/g after 500 cycles even at a higher current density of 2.0 A/g,which are much better than their counterparts of bare CuO and Co_(3)O_(4).The enhanced lithium storage performance can be attributed to the synergistic effect of the CuO and Co_(3)O_(4)heterostructure with hollow spherical morphology,which greatly enhances the charge/electrolyte transfer and effectively buffers the volume changes upon lithiation/delithiation cycling. | Junjun Zhang Huiying Lu Tianhao Yao Xin Ji Qingmiao Zhang Lingjie Meng Jianmin Feng Hongkang Wang | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 17 | Intermittent F-actin Perturbations by Magnetic Fields Inhibit Breast Cancer Metastasis显示文摘F-actin(filamentous actin)has been shown to be sensitive to mechanical stimuli and play critical roles in cell attachment,migration,and cancer metastasis,but there are very limited ways to perturb F-actin dynamics with low cell toxicity.Magnetic field is a noninvasive and reversible physical tool that can easily penetrate cells and human bodies.Here,we show that 0.1/0.4-T 4.2-Hz moderate-intensity low-frequency rotating magnetic field-induced electric field could directly decrease F-actin formation in vitro and in vivo,which results in decreased breast cancer cell migration,invasion,and attachment.Moreover,lowfrequency rotating magnetic fields generated significantly different effects on F-actin in breast cancer vs.noncancerous cells,including F-actin number and their recovery after magnetic field retrieval.Using an intermittent treatment modality,low-frequency rotating magnetic fields could significantly reduce mouse breast cancer metastasis,prolong mouse survival by 31.5 to 46.0%(P<0.0001),and improve their overall physical condition.Therefore,our work demonstrates that low-frequency rotating magnetic fields not only can be used as a research tool to perturb F-actin but also can inhibit breast cancer metastasis through F-actin modulation while having minimum effects on normal cells,which reveals their potential to be developed as temporal-controlled,noninvasive,and high-penetration physical treatments for metastatic cancer. | Xinmiao Ji Xiaofei Tian Shuang Feng Lei Zhang Junjun Wang Ruowen Guo Yiming Zhu Xin Yu Yongsen Zhang Haifeng Du Vitalii Zablotskii Xin Zhang | 2023 | Research2023，，4： | 0 |
| 18 | Magnetic Fields Affect Alcoholic Liver Disease by Liver Cell Oxidative Stress and Proliferation Regulation显示文摘It is well known that alcohol consumption leads to substantially increased free radical levels and health risks,which lacks effective treatment besides alcohol abstinence.Here,we compared different static magnetic field(SMF)settings and found that a downward quasi-uniform SMF of~0.1 to 0.2 T could effectively alleviate alcohol-induced liver damage and lipid accumulation and improve hepatic function.SMFs of two different directions can reduce the inflammation,reactive oxygen species levels,and oxidative stress in the liver,while the downward SMF had more obvious effects.Moreover,we found that the upward direction SMF of~0.1 to 0.2 T could inhibit DNA synthesis and regeneration in hepatocytes,which caused detrimental effects on the lifespan of'heavy drinking'mice.In contrast,the downward SMF prolongs survival of'heavy drinking'mice.On one hand,our study shows that~0.1 to 0.2 T moderate quasi-uniform SMFs with a downward direction have great promises to be developed into a physical method to reduce alcohol-induced liver damage;on the other hand,although the internationally recognized upper limit for SMF public exposure is 0.4 T,people should also pay extra attention to SMF strength,direction,and inhomogeneity that could generate harmful effects on specific severe pathological conditions. | Chao Song Hanxiao Chen Biao Yu Lei Zhang Junjun Wang Chuanlin Feng Xingxing Yang Xiaofei Tian Yixiang Fan Xinmiao Ji Hua Wang Can Xie Xin Zhang | 2023 | Research2023，，4： | 0 |
| 19 | Fluoride removal from secondary effluent of the graphite industry using electrodialysis:Optimization with response surface methodology显示文摘Response surface methodology was utilized to model and optimize the operational variables for defluoridation using an electrodialysis process as the treatment of secondary effluent of the graphite industry. Experiments were conducted using a Box-Behnken surface statistical design in order to evaluate the effects and the interaction of the influential variables including the operational voltage, initial fluoride concentration and flow rate. The regression models for defluoridation and energy consumption responses were statistically validated using analysis of variance (ANOVA);high coefficient of determination values (R^2 = 0.9772 and R^2 = 0.9814;respectively) were obtained. The quadratic model exhibited high reproducibility and a good fit of the experimental data. The optimum values of the initial fluoride concentration, voltage and flow rate were found to be 13.9 mg/L, 13.4 V, 102.5 L/h, respectively. A fluoride removal efficiency of 99.69% was observed under optimum conditions for the treatment of the secondary effluent of the graphite industry. | Xiaomeng Wang Ning Li Jianye Li Junjun Feng Zhun Ma Yuting Xu Yongchao Sun Dongmei Xu Jian Wang Xueli Gao Jun Gao | 2019 | Frontiers of Environmental Science & Engineering2019，13，4： | 0 |
| 20 | Highly efficient solid-state luminescence of carbonized polymer dots without matrix显示文摘Development of high-performance solid state luminescent carbon-based nanomaterials remains challenging.Here,strong blue-green fluorescent carbonized polymer dots(CPDs)from o-aminobenzenethiol and thiosalicylic acid(o ABT-TSA-CPDs)with an absolute photoluminescence quantum yield(PLQY)of 76%in solid state without matrix were synthesized.Through adjusting the reaction temperature and time,the PL centers were proved to be carbon core state and surface state associated to carbonyl group which was the source of strong fluorescence emission in solid state.The mechanism of the unique phenomenon of enhanced emission from ethanol solution(PLQY=7%)to powder(PLQY=76%)was investigated by analyzing the chemical properties and structures of o ABT-TSA-CPDs at different temperatures and o ABT-TSACPDs/PVC composites,and was confirmed as fixation of PL centers. | Rui Li Junjun Liu Chunlei Xia Tanglue Feng Zhicheng Zhu Bai Yang | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
