| 1 | Endothelial cells-targeted soluble human Delta-like 4 suppresses both physiological and pathological ocular angiogenesis显示文摘Due to its essential roles in angiogenesis, Notch pathway has emerged as an attractive target for the treatment of pathologic angiogenesis. Although both activation and blockage of Notch signal can impede angiogenesis, activation of Notch signal may be more promising because it was shown that long-term Notch signal blockage resulted in vessel neoplasm. However, an in vivo deliverable Notch ligand with highly efficient Notch-activating capacity has not been developed. Among all the Notch ligands, Delta-like4(Dll4) is specifically involved in angiogenesis. In this study, we generated a novel soluble Notch ligand h D4 R, which consists of the Delta-Serrate-Lag-2 fragment of human Dll4 and an arginine-glycine-aspartate(RGD) motif targeting endothelial cells(ECs). We demonstrated that h D4 R could bind to ECs through its RGD motif and effectively triggered Notch signaling in ECs. Further, we confirmed that h D4 R could suppress angiogenesis in vitro as manifested by network formation assay and sprouting assay. More importantly, h D4 R efficiently repressed neonatal retinal angiogenesis and laser-induced choroidal neovascularization(CNV) as well in vivo. In conclusion, we have developed an in vivo deliverable Notch ligand h D4 R, which suppresses angiogenesis both in vitro and in vivo, thus providing a new approach to tackle excessive angiogenesis relevant disease such as CNV. | YAN XianChun YANG ZiYan CHEN Yan LI Na WANG Li DOU GuoRui LIU Yuan DUAN JuanLi FENG Lei DENG SanMing HAN Hua ZHANG Ping | 2015 | Science China(Life Sciences)2015，58，5： | 5 |
| 2 | Spirulina platensis aqueous extracts ameliorate colonic mucosal damage and modulate gut microbiota disorder in mice with ulcerative colitis by inhibiting inflammation and oxidative stress显示文摘Ulcerative colitis(UC)is a chronic and recurrent inflammatory bowel disease(IBD)that has become a major gastroenterologic problem during recent decades.Numerous complicating factors are involved in UC development such as oxidative stress,inflammation,and microbiota disorder.These factors exacerbate damage to the intestinal mucosal barrier.Spirulina platensis is a commercial alga with various biological activity that is widely used as a functional ingredient in food and beverage products.However,there have been few studies on the treatment of UC using S.platensis aqueous extracts(SP),and the underlying mechanism of action of SP against UC has not yet been elucidated.Herein,we aimed to investigate the modulatory effect of SP on microbiota disorders in UC mice and clarify the underlying mechanisms by which SP alleviates damage to the intestinal mucosal barrier.Dextran sulfate sodium(DSS)was used to establish a normal human colonic epithelial cell(NCM460)injury model and UC animal model.The mitochondrial membrane potential assay 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)and staining with Annexin V-fluorescein isothiocyanate(FITC)/propidium iodide(PI)and Hoechst 33258 were carried out to determine the effects of SP on the NCM460 cell injury model.Moreover,hematoxylin and eosin(H&E)staining,transmission electron microscopy(TEM),enzyme-linked immunosorbent assay(ELISA),quantitative real-time polymerase chain reaction(qPCR),western blot,and 16S ribosomal DNA(rDNA)sequencing were used to explore the effects and underlying mechanisms of action of SP on UC in C57BL/6 mice.In vitro studies showed that SP alleviated DSS-induced NCM460 cell injury.SP also significantly reduced the excessive generation of intracellular reactive oxygen species(ROS)and prevented mitochondrial membrane potential reduction after DSS challenge.In vivo studies indicated that SP administration could alleviate the severity of DSS-induced colonic mucosal damage compared with the control group.Inhibition of inflammation and oxidative stress was associated with increases in the activity of antioxidant enzymes and the expression of tight junction proteins(TJs)post-SP treatment.SP improved gut microbiota disorder mainly by increasing antioxidant enzyme activity and the expression of TJs in the colon.Our findings demonstrate that the protective effect of SP against UC is based on its inhibition of pro-inflammatory cytokine overproduction,inhibition of DSS-induced ROS production,and enhanced expression of antioxidant enzymes and TJs in the colonic mucosal barrier. | Jian WANG Liqian SU Lun ZHANG Jiali ZENG Qingru CHEN Rui DENG Ziyan WANG Weidong KUANG Xiaobao JIN Shuiqing GUI Yinghua XU Xuemei LU | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，6： | 3 |
| 3 | Stereoselective separation and determination of quizalofopethyl in tobacco by ultra-performance convergence chromatography with tandem mass spectrometry显示文摘The purpose of this study was to develop and validate a novel and sensitive method for simultaneous enantiomeric analysis of quizalofop-ethyl in tobacco using ultra-performance converge nee chromatography with tandem mass spectrometry(UPC-MS/MS).Sample preparation prior to UPC^2-MS/MS analysis followed a QuEChERS(quick,easy,cheap,effective,rugged and safe)method.The UPC^2-MS/MS method used an Acquity UPC2 Trefoil CEL2 column with a mobile phase of CO2 and methanol.The injection volume was 2 μL and run-time was 6 min with the mobile phase running at 2.0 mL/min flow rate.Column temperature,auto back pressure regulator pressure(ABPR),and modifier solvent were optimized for separation efficiency.Under the optimal conditio ns,the recoveries for all the ena ntiomers were 81.3%-94.8% with relative standard deviations(RSD)less than 5.0% at 0.1,1.0 and 2.0 mg/kg levels,respectively.Good coefficients of determination(R^2≥0.993 7)were achieved for all the studied enantiomers in the tobacco over the concentration range of 10-250 ng/mL.The limits of detection(LODs)varied from 0.02 mg/kg to 0.04 mg/kg,and the limits of quantification(LOQs)were ≤ 0.13 mg/kg.The results confirm that the proposed method is green,convenient and reliable for the enantioselective determination of the enantiomers of quizalofop-ethyl in tobacco. | YANG Fei TANG Gangling FAN Ziyan WANG Ying LIU Shanshan DENG Huimin BIAN Zhaoyang LI Zhonghao | 2018 | 烟草科技2018，51，A01： | 1 |
| 4 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 5 | Stable large-area monodomain in as-grown bulk ferroelectric single crystal Sn_(2)P_(2)S_(6)显示文摘Driven by the minimization of total energy,the multi-domain morphology is preferred in as-grown ferroelectrics to reduce the depolarization and strain energy during the paraelectric to ferroelectric phase transition.However,the complicated multi-domain is not desirable for certain high-performance ferroelectric electro-optic devices.In this work,we achieve a reproducible and stable large-area monodomain in as-grown bulk ferroelectric single crystal Sn_(2)P_(2)S_(6).The monodomain dominates the entire single crystal,which is attributed to the internal charge carriers from the photoexcited disproportionation reaction of Sn ions.The charge carriers effectively screen the depolarization field and therefore decrease the depolarization energy and facilitate the formation of monodomain.This work offers a potential approach for engineering bulk ferroelectrics with a stable monodomain,which is desirable for the high-performance ferroelectric electro-optic devices. | Yingzhuo Lun Jiaqian Kang Wenfu Zhu Jianming Deng Xingan Jiang Cheng Zhu Qi Ren Xian Zi Ziyan Gao Tianlong Xia Zishuo Yao Xueyun Wang Jiawang Hong | 2023 | Journal of Advanced Dielectrics2023，13，3： | 0 |
| 6 | Automated and refined wetland mapping of Dongting Lake using migrated training samples based on temporally dense Sentinel 1/2 imagery显示文摘Wetlands provide vital ecological services for both humans and environment,necessitating continuous,refined and up-to-date mapping of wetlands for conservation and management.in this study,we developed an automated and refined wetland mapping framework integrating training sample migration method,supervised machine learning and knowledge-driven rules using Google Earth Engine(GEE)platform and open-source geospatial tools.We applied the framework to temporally dense Sentinel-1/2 imagery to produce annual refined wetland maps of the Dongting Lake Wetland(DLW)during 2015-2021.First,the continuous change detection(CCD)algorithm was utilized to migrate stable training samples.Then,annual 10 m preliminary land cover maps with 9 classes were produced using random forest algorithm and migrated samples.Ultimately,annual 10 m refined wetland maps were generated based on preliminary land cover maps via knowledge-driven rules from geometric features and available water-related inventories,with Overall Accuracy(OA)ranging from 81.82%(2015)to 93.84%(2020)and Kappa Coefficient(KC)between 0.73(2015)and 0.91(2020),demonstrating satisfactory performance and substantial potential for accurate,timely and type-refined wetland mapping.Our methodological framework allows rapid and accurate monitoring of wetland dynamics and could provide valuable information and methodological support for monitoring,conservation and sustainable development of wetland ecosystem. | Yawen Deng Weiguo Jiang Ziyan Ling Xiaoya Wang Kaifeng Peng Zhuo Li | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 7 | Soil microbiome mediated nutrients decline during forest degradation process显示文摘Degradation succession in forests is an important and serious land use/cover change problem in ecology,and during these processes soil microbial communities mediate the recycling of most important nutrients.To reveal the effect of degradation succession processes on soil microbial community diversity,structure,and species interrelationships,we collected abundant samples(21 per vegetation type)in broad-leaved forest,coniferous forest,and meadow to observe the microbial community dynamics.The results showed that diversity and structure of soil prokaryotic and fungal communities responded differently to different forest degradation processes,diversity of soil microbial communities increased during degradation processes.Soil microbial communities abundance changes may indicate that prokaryotic communities showed a living strategies change as an ecological adaption to harsh conditions during forest degradation process.While for fungal communities,their abundance changes may indicate that environmental selection pressure and plant selectivity during forest degradation process.Changes in soil prokaryotic communities and fungal communities were both correlated with soil carbon and nitrogen loss.The soil microbial interaction network analysis indicated more complex species interrelationships formed due to the loss of soil nutrients during degradation succession processes,suggesting soil microbial communities might form more complex and stable networks to resist the external disturbance of soil nutrient loss.All results suggested soil microorganisms,including bacteria,archaea and fungi,all involved in the soil nutrient decline during the forest degradation process. | Yangying Liu Shang Wang Zhujun Wang Zhaojing Zhang Huayu Qin Ziyan Wei Kai Feng Shuzhen Li Yueni Wu Huaqun Yin Hui Li Ye Deng | 2019 | Soil Ecology Letters2019，1，1： | 0 |
