2Long-term ex vivo monitoring of in vivo microRNA activity in liver using a secreted luciferase sensor显示文摘Technology for monitoring in vivo microRNA (miRNA) activity is extremely important for elucidating miRNA biology.However,in vivo studies of miRNA have been hampered by the lack of a convenient approach to reliably reflect real-time functional changes in miRNAs.Sensors for miRNA were developed by adding miRNA target sequences to the 3'-untranslated region of Gaussia princeps luciferase (Gluc) mRNA.These sensors were then evaluated in vitro and in vivo by measuring Gluc activity in cell supernatants and in peripheral blood.Sensors driven by the CMV promoter were effective for monitoring miR-122 in living cells,but not for the long-term monitoring of miR-122 or miR-142 in mouse liver because of CMV-promoter silencing.Replacing the CMV promoter with a CAG promoter rendered these sensors effective for the long-term monitoring of relevant liver miRNA activities.We subsequently used the CAG-promoter-based sensor for the long-term monitoring of endogenous liver miR-122,miR142 and miR-34a activities,as well as for exogenous miR-34a activity.Our study demonstrates that real-time in vivo activities of miRNAs can be continuously and conveniently detected in mouse liver using the sensors that we have developed.WANG Gang DONG XiaoYan HU JianYang TIAN WenHong YUCHI Jie WANG Yue WU XiaoBing 2011Science China(Life Sciences)2011,54,5:6
3A survey on deep learning-based Monte Carlo denoising显示文摘Monte Carlo(MC)integration is used ubiquitously in realistic image synthesis because of its flexibility and generality.However,the integration has to balance estimator bias and variance,which causes visually distracting noise with low sample counts.Existing solutions fall into two categories,in-process sampling schemes and post-processing reconstruction schemes.This report summarizes recent trends in the post-processing reconstruction scheme.Recent years have seen increasing attention and significant progress in denoising MC rendering with deep learning,by training neural networks to reconstruct denoised rendering results from sparse MC samples.Many of these techniques show promising results in real-world applications,and this report aims to provide an assessment of these approaches for practitioners and researchers.Yuchi Huo Sung-eui Yoon 2021Computational Visual Media2021,7,2:5

5Reproductive Behavior and Underwater Calls in the Emei Mustache Toad,Leptobrachium boringii显示文摘The Emei mustache toad,Leptobrachium boringii(Megophryidae),is terrestrial but breeds in permanent streams.Primarily,it has a polygynous mating system and polyandry also occurs.The species vigorously defends submerged nest sites.We report on a reproductive study at Mt.Emei,western China conducted in 2004,2006,2007,2009,and 2011 during the breeding season.Males produce both advertisement and courtship calls underwater,and the latter differs from the former in having an additional trill-like last note of low intensity.Females might determine the oviposition location and hence the egg mass location.A low,submissive posture can be adopted by the male to avoid being attacked by other males.When fi ghting,the maxillary nuptial spines are employed as weapons,and males hold their opponents on their spines with the forelimbs that enlarge during the breeding season.Male body size and the quantity of fi ght wounds on its ventral side are positively correlated.Satellite male mating might exist in L.boringii.Additionally,underwater calls from another population of this species and a population of L.leishanense generally are similar to those of the population from Mt.Emei.Yuchi ZHENG Dingqi RAO Robert W.MURPHY Xiaomao ZENG 2011Asian Herpetological Research2011,2,4:5
6High power and stable P-doped yolk-shell structured Si@C anode simultaneously enhancing conductivity and Li^(+)diffusion kinetics显示文摘Silicon is a low price and high capacity ancxje material for lithium-ion batteries.The yolk-shell structure can effectively accommodate Si expansion to improve stability.However,the limited rate performance of Si anodes can't meet people's growing demand for high power density.Herein,the phosphorus-doped yolk-shell Si@C materials(P-doped Si@C)were prepared through carbon coating on P-doped Si/SiO_(x)matrix to obtain high power and stable devices.Therefore,the as-prepared P-doped Si@C electrodes delivered a rapid increase in Coulombic efficiency from 74.4%to 99.6%after only 6 cycles,high capacity retention of-95%over 800 cycles at 4 A·g^(-1),and great rate capability(510 mAh·g^(-1)at 35 A·g^(-1)).As a result,P-doped Si@C anodes paired with commercial activated carbon and LiFePO_(4)cathode to assemble lithium-ion capacitor(high power density of〜61,080 W·kg^(-1)at 20 A·g^(-1))and lithium-ion full cell(good rate performance with 68.3 mAh·g^(-1)at 5 C),respectively.This work can provide an effective way tofurther improve power density and stability for energy storage devices.Ming Chen Qinnan Zhou Jiantao Zai Asma Iqbal TsegayeTadesse Tsega Boxu Dong Xuejiao Liu Yuchi Zhang Changyu Yan Liang Zhao Ali Nazakat SharelPeisan E CheeTongJohn Low Xuefeng Qian 2021Nano Research2021,14,4:5
7Evaluation of miR-122-regulated suicide gene therapy for hepatocellular carcinoma in an orthotopic mouse model显示文摘Objective:Intratumoral administration of adenoviral vector encoding herpes simplex virus(HSV)thymidine kinase(TK)gene(Ad-TK)followed by systemic ganciclovir(GCV)is an effective approach in treating experimental hepatocellular carcinoma(HCC).However,hepatotoxicity due to unwanted vector spread and suicide gene expression limited the application of this therapy.miR-122 is an abundant,liver-specific microRNA whose expression is decreased in human primary HCC and HCC-derived cell lines.These different expression profiles provide an opportunity to induce tumor-specific gene expression by miR-122 regulation.Methods:By inserting miR-122 target sequences(miR-122T)in the 3'untranslated region(UTR)of TK gene,we constructed adenovirus(Ad)vectors expressing miR-122-regulated TK(Ad-TK-122T)and report genes.After intratumoral administration of Ad vectors into an orthotopic miR-122-deficient HCC mouse model,we observed the miR-122-regulated transgene expression and assessed the antitumor activity and safety of Ad-TK-122T.Results:Insertion of miR-122T specifically down-regulated transgene expression in vitro and selectively protected the miR-122-positive cells from killing by TK/GCV treatment.Insertion of miR-122T led to significant reduction of tansgene expression in the liver without inhibition of its expression in tumors in vivo,resulting in an 11-fold improvement of tumor-specific transgene expression.Intratumoral injection of Ad vectors mediated TK/GCV system led to a vector dosage-dependent regression of tumor.The insertion of miR-122T does not influence the antitumor effects of suicide gene therapy.Whereas mice administrated with Ad-TK showed severe lethal hepatotoxicity at the effective therapeutic dose,no liver damage was found in Ad-TK-122T group.Conclusions:miR-122-regulated TK expression achieved effective anti-tumor effects and increased the safety of intratumoral delivery of adenovirus-mediated TK/GCV gene therapy for miR-122-deficient HCC.Gang Wang Xiaoyan Dong Wenhong Tian Yue Lu Jianyan Hu Yunfan Liu Jie Yuchi Xiaobing Wu 2013Chinese Journal of Cancer Research2013,25,6:5
8Microstructure and composition engineering Yb single-filled CoSb_(3) for high thermoelectric and mechanical performances显示文摘A broad tunability of the thermoelectric and mechanical properties of CoSb_(3) has been demonstrated by adjusting the composition with the addition of an increasing number of elements.However,such a strategy may negatively impact processing repeatability and composition control.In this work,singleelement-filled skutterudite is engineered to have high thermoelectric and mechanical performances.Increased Yb filling fraction is found to increase phonon scattering,whereas cryogenic grinding contributes additional microstructural scattering.A peak zT of 1.55 and an average zT of about 1.09,which is comparable to the reported results of multiple-filled SKDs,are realized by the combination of simple composition and microstructure engineering.Furthermore,the mechanical properties of Yb single-filled CoSb_(3) skutterudite are improved by manipulation of the microstructure through cryogenic grinding.These findings highlight the realistic prospect of producing high-performance thermoelectric materials with reduced compositional complexity.Zhenxing Zhou Matthias T.Agne Qihao Zhang Shun Wan Qingfeng Song Qing Xu Xiaofang Lu Shijia Gu Yuchi Fan Wan Jiang Gerald Jeffrey Snyder Lianjun Wang 2019Journal of Materiomics2019,5,4:4
9Synthesis and Device Applications of High-Density Aligned Carbon Nanotubes Using Low-Pressure Chemical Vapor Deposition and Stacked Multiple Transfer显示文摘For nanotube-based electronics to become a viable alternative to silicon technology,high-density aligned carbon nanotubes are essential.In this paper,we report the combined use of low-pressure chemical vapor deposition and stacked multiple transfer to achieve high-density aligned nanotubes.By using an optimized nanotube synthesis recipe,we have achieved high-density aligned carbon nanotubes with density as high as 30 tubes/μm.In addition,a facile stacked multiple transfer technique has been developed to further increase the nanotube density to 55 tubes/μm.Furthermore,high-performance submicron carbon nanotube field-effect transistors have been fabricated on the high-density aligned nanotubes.Before removing the metallic nanotubes by electrical breakdown,the devices exhibit on-current density of 92.4μA/μm and normalized transconductance of 13.3μS/μm.Moreover,benchmarking with the aligned carbon nanotube transistors in the literature indicates that our devices exhibit the best performance so far,which is attributed to both the increased nanotube density and scaling down of channel length.This study shows the great potential of using such high-density aligned nanotubes for high performance nanoelectronics and analog/RF applications.Chuan Wang Koungmin Ryu Lewis Gomez De Arco Alexander Badmaev Jialu Zhang Xue Lin Yuchi Che Chongwu Zhou 2010Nano Research2010,3,12:3
10Evolution of the Pearl River and its Implication for East Asian Continental Landscape Reversion显示文摘As the link connecting the South China Continent and the northern South China Sea(SCS),the Pearl River is the focus of sedimentology and petroleum geology research.Its evolutionary process and controlling factors are of great significance in revealing the East Asian continental landscape reorganization during the Late Cenozoic.Based on published data,’source-to-sink’provenance analyses allow systematic deliberation on the birth and evolutionary history of the Pearl River.Close to the Oligocene/Miocene boundary,an abrupt shift in the sedimentary composition indicates significant westward and northward expansion of the river’s watershed area,followed by the establishment of a near-modern fluvial network.This sedimentary change generally concurred with a series of regional geological events,including the onset of the Yangtze throughflow,large-scale development of the loess plateau,and formation of the northwestern arid zone and Asian Monsoon system.These major changes in the geology-climate-ecoenvironment system are in close response to the process of the Cenozoic Xizang(Tibetan)Plateau uplift.Consequently,the East Asian continental landscape and most of midCenozoic drainage systems underwent critical reversion into east-tilting,or east-flowing networks.ZHANG Hao CUI Yuchi QIAO Peijun ZHAO Meng XIANG Xuhong 2021Acta Geologica Sinica(English Edition)2021,95,1:3
11Noise control and utility:From regulatory network to spatial patterning显示文摘Stochasticity(or noise) at cellular and molecular levels has been observed extensively as a universal feature for living systems. However, how living systems deal with noise while performing desirable biological functions remains a major mystery. Regulatory network configurations, such as their topology and timescale, are shown to be critical in attenuating noise, and noise is also found to facilitate cell fate decision. Here we review major recent findings on noise attenuation through regulatory control, the benefit of noise via noise-induced cellular plasticity during developmental patterning and summarize key principles underlying noise control.Qing Nie Lingxia Qiao Yuchi Qiu Lei Zhang Wei Zhao 2020Science China Mathematics2020,63,3:3
12Porous N-doped Ni@SiO_(2)/graphene network: Three-dimensional hierarchical architecture for strong and broad electromagnetic wave absorption显示文摘Electromagnetic wave absorber is critical for reducing increasingly serious electromagnetic wave pollu-tion,however,the development of lightweight and broadband microwave absorbers remains a pressing challenge.We report here the rational design and synthesis of N-doped Ni@SiO_(2)/graphene composite con-structed from 3D interconnected porous graphene network and Ni@SiO_(2) core-shell architecture,which fulfills lightweight and broadband requirements while exhibiting highly efficient electromagnetic wave absorption.The porous graphene network,functioning both as lightweight support and dielectric medi-ator,was synthesized via NaCl template-assisted high-temperature calcination method.Upon uniformly attached with core-shell Ni@SiO_(2) on the surface,the resulting abundant heterogeneous interfaces con-structed by graphene-Ni and Ni-SiO_(2) strongly reinforce polarization loss.The presence of low dielectric SiO_(2) allows facile tuning of the complex permittivity of ternary composite by adjusting coating thick-ness to balance the attenuation ability and impedance matching.Moreover,further N-doping of graphene assists in the optimization of dielectric loss ability.Taking account of the advantages arising from the porous hierarchical architecture,multiple absorption centers and diverse interfaces,the lightweight com-posite exhibits an ultra-strong reflection loss(RL)value of-71.13 dB at 13.76 GHz with a thickness of 2.46 mm and broad effective absorption bandwidth of 7.04 GHz at a low filler content of 15 wt.%.More importantly,the effective absorption range covers 13.28 GHz(4.72-18 GHz)with the optimized thickness of 1.6-5 mm,representing 83%of the whole range of frequencies.Our results demonstrate that the novel 3D porous N-doped Ni@SiO_(2)/graphene network with hierarchical architecture is a promising candidate for high-performance electromagnetic wave absorption.Rui Guo Qi Zheng Lianjun Wang Yuchi Fan Wan Jiang 2022Journal of Materials Science & Technology2022,,11:3

14Discovery of a series of dimethoxybenzene FGFR inhibitors with 5H-pyrrolo[2,3-b]pyrazine scaffold: structure–activity relationship, crystal structural characterization and in vivo study显示文摘Genomic alterations are commonly found in the signaling pathways of fibroblast growth factor receptors(FGFRs). Although there is no selective FGFR inhibitors in market, several promising inhibitors have been investigated in clinical trials, and showed encouraging efficacies in patients. By designing a hybrid between the FGFR-selectivity-enhancing motif dimethoxybenzene group and our previously identified novel scaffold, we discovered a new series of potent FGFR inhibitors, with the best one showing sub-nanomolar enzymatic activity. After several round of optimization and with the solved crystal structure, detailed structure–activity relationship was elaborated. Together with in vitro metabolic stability tests and in vivo pharmacokinetic profiling, a representative compound(35) was selected and tested in xenograft mouse model, and the result demonstrated that inhibitor 35 was effective against tumors with FGFR genetic alterations, exhibiting potential for further development.Peng Wei Bo Liu Ruifeng Wang Yinglei Gao Lanlan Li Yuchi Ma Zhiwei Qian Yuelei Chen Maosheng Cheng Meiyu Geng Jingkang Shen Dongmei Zhao Jing Ai Bing Xiong 2019Acta Pharmaceutica Sinica B2019,9,2:2
15Review of Antiswing Control of Shipboard Cranes显示文摘Shipboard cranes are extensively utilized in numerous fields such as cargo transferring and offshore engineering.The control of shipboard cranes,especially the antiswing control of payloads,has attracted much research attention due to their typical underactuation characteristics and complicated dynamics.Through comparisons of the traditional land-fixed cranes,a brief review on modeling and dynamics analysis is presented to illustrate the tremendous challenges and difficulties in controller design for shipboard cranes.A comprehensive review and brief analysis of shipboard crane control strategies are further presented.Some future research directions are also put forward for reference.It is expected that the paper will be useful for improving existing control schemes and generating novel control approaches for shipboard crane systems.Yuchi Cao Tieshan Li 2020IEEE/CAA Journal of Automatica Sinica2020,7,2:2

17Recent progress in the structural study of ion channels as insecticide targets显示文摘Ion channels,many expressed in insect neural and muscular systems,have drawn huge attention as primary targets of insecticides.With the recent technical breakthroughs in structural biology,especially in cryo-electron microscopy(cryo-EM),many new high-resolution structures of ion channel targets,apo or in complex with insecticides,have been solved,shedding light on the molecular mechanism of action of the insecticides and resistance mutations.These structures also provide accurate templates for structure-based insecticide screening and rational design.This review summarizes the recent progress in the structural studies of 5 ion channel families:the ryanodine receptor(RyR),the nicotinic acetylcholine receptor(nAChR),the voltage-gated sodium channel(VGSC),the transient receptor potential(TRP)channel,and the ligand-gated chloride channel(LGCC).We address the selectivity of the channel-targeting insecticides by examining the conservation of key coordinating residues revealed by the structures.The possible resistance mechanisms are proposed based on the locations of the identified resistance mutations on the 3D structures of the target channels and their impacts on the binding of insecticides.Finally,we discuss how to develop“green”insecticides with a novel mode of action based on these high-resolution structures to overcome the resistance.Hadiatullah Hadiatullah Yongliang Zhang Arthur Samurkas Yunxuan Xie Rajamanikandan Sundarraj Han Zuilhof Jianjun Qiao Zhiguang Yuchi 2022Insect Science2022,29,6:2
18Cenozoic Sea-land Transition and its Petroleum Geological Significance in the Northern South China Sea显示文摘The process of Cenozoic sea-land changes in the northern South China Sea(SCS)controlled the sedimentary filling pattern and played an important role in the petroleum geological characteristics of the northern marginal sedimentary basins.Under the control of the opening process of the SCS,the northern SCS Cenozoic transgression generally showed the characteristics of early in the east and late in the west,and early in the south and late in the north.The initial transgression occurred in the Eocene in the Taixinan Basin(TXNB)of the eastern SCS,while the transgression occurred until the Pliocene in the Yinggehai Basin(YGHB)of the western SCS.International Ocean Discovery Program(IODP)expeditions(Expeditions 367/368)revealed that the initial transgression of the SCS basin occurred at approximately 34 Ma,which was the initial opening time of the SCS.The period of drastic changes in the sedimentary environment caused by large-scale transgression corresponded to the opening time of the southwestern subbasin(approximately 23 Ma),which also represented the peak of the spreading of the SCS.The sea-land transition process controls the distribution of alternating continent-marine facies,marine facies source rocks and reservoirs in the basins.The marine facies source rocks of the basins in the northern SCS have a trend of gradually becoming younger from east to west,which is consistent with the regional process of gradual transgression from east to west.Regional sea-level changes were comprehensively influenced by SCS opening and global sea-level changes.These processes led to the early development in the east and south and late development in the west and north for the carbonate platform in the SCS.Carbonate platforms form another type of'selfgenerating and self-accumulating'oil-gas reservoir in the northern SCS.The sea-land transition controlled the depositional filling patterns of different basins and laid the foundation of marine deposits for oil and gas resources.The source-reservoircap assemblage in the northern SCS was controlled horizontally by provenance supply and sedimentary environmental changes caused by sea-land transition and vertically by the tectonic evolution of the SCS and regional sea-level changes.ZHAO Zhigang ZHANG Hao CUI Yuchi TANG Wu QIAO Peijun 2021Acta Geologica Sinica(English Edition)2021,95,1:2
19In vitro activity of allicin combined with two antibiotics on intestinal Shigella显示文摘Objective: We aimed to evaluate the combined antibacterial effects of allicin in combination with levofloxacin and ceftriaxone on Shigella isolated from the intestinal tract in vitro. Materials and Methods: Using a checkerboard design, broth microdilution assay was used to test the effects of the compounds on the organism. We also determined the MIC of the two groups of antibacterial drugs against 30 strains of Shigella and calculated the fractional inhibitory concentration(FIC) index, to judge the combination effect. Result: After the combined application of allicin and ceftriaxone the MIC decreased significantly. Distribution of the FIC index was as follows: FIC ≤0.5, accounting for 10%; 0.5< FIC ≤1.0, accounting for 60%; 1 < FIC ≤2, accounting for 30%; FIC >2, percentage is zero. After combined application of allicin and levofloxacin, distribution of FIC index was as follows: FIC≤0.5, ratio is zero; 0.5< FIC ≤1, accounting for 56.7%; 1 < FIC ≤2, accounting for 43.3%; FIC >2, ratio is zero. Conclusion: After the combined use of ceftriaxone, levofloxacin, and allicin, most of the tests showed synergistic effects and additive effects on Shigella, while some of them showed no correlation and no antagonistic effect.Yuchi Jia Xiaomei Wu 2017国际感染病学(电子版)2017,6,1:2
20Influence of Collective Esophageal Speech Training on Self-efficacy in Chinese Laryngectomees:A Pretest-posttest Group Study显示文摘Total laryngectomy affects the speaking functions of many patients.Speech deprivation has great impacts on the quality of life of patients,especially on self-efficacy.Learning esophageal speech represents a way to help laryngectomees speak again.The purpose of this study was to determine the influence of collective esophageal speech training on self-efficacy of laryngectomees.In this study,28 patients and 30 family members were included.The participants received information about training via telephone or a WeChat group.Collective esophageal speech training was used to educate laryngectomees on esophageal speech.Before and after collective esophageal speech training,all participants completed the General Self-Efficacy Scale(GSES)to assess their perceptions on self-efficacy.Through the training,laryngectomees recovered their speech.After the training,the self-efficacy scores of laryngectomees were higher than those before the training,with significant differences noted(P<0.05).However,family members'scores did not change significantly.In conclusion,collective esophageal speech training is not only convenient and economical,but also improves self-efficacy and confidence of laryngectomees.Greater self-efficacy is helpful for laryngectomees to master esophageal speech and improve their quality of life.In addition,more attention should be focused on improving the self-efficacy of family members and making them give full play to their talent and potential on laryngectomees'voice rehabilitation.Qing CHEN Jing LUO Jun-ping LI Dan-ni JIAN Yong YUCHI Hong-xia RUAN Xiao-li HUANG Miao WANG 2019Current Medical Science2019,39,5:2
