| 1 | Polyamine Accumulation in Transgenic Tomato Enhances the Tolerance to High Temperature Stress显示文摘Polyamines play an important role in plant response to abiotic stress.S-adenosyl-l-methionine decarboxylase(SAMDC) is one of the key regulatory enzymes in the biosynthesis of polyamines.In order to better understand the effect of regulation of polyamine biosynthesis on the tolerance of high-temperature stress in tomato,SAMDC cDNA isolated from Saccharomyces cerevisiae was introduced into tomato genome by means of Agrobacterium tumefaciens through leaf disc transformation.Transgene and expression was confirmed by Southern and Northern blot analyses,respectively.Transgenic plants expressing yeast SAMDC produced 1.7-to 2.4-fold higher levels of spermidine and spermine than wild-type plants under high temperature stress,and enhanced antioxidant enzyme activity and the protection of membrane lipid peroxidation was also observed.This subsequently improved the efficiency of CO2 assimilation and protected the plants from high temperature stress,which indicated that the transgenic tomato presented an enhanced tolerance to high temperature stress(38℃) compared with wild-type plants.Our results demonstrated clearly that increasing polyamine biosynthesis in plants may be a means of creating high temperature-tolerant germplasm. | Lin Cheng Yijing Zou Shuli Ding Jiajing Zhang Xiaolin Yu Jiashu Cao Gang Lu | 2009 | Journal of Integrative Plant Biology2009，51，5： | 16 |
| 2 | Control of de novo root regeneration efficiency by developmental status of Arabidopsis leaf explants显示文摘De novo root regeneration(DNRR) has wide applications in agriculture such as those related to cutting technology. Detached Arabidopsis thaliana leaf explants can regenerate adventitious roots without added hormones. The regenerative ability is highly dependent on the developmental status of the leaf. An immature leaf has a higher regenerative ability, while a mature leaf is difficult to regenerate. Using RNASeq analysis, we showed that the expression levels of many genes, including those in the auxin network,changed during leaf maturation. Particularly, the expression levels of many YUCCA(YUC) genes in the auxin biosynthesis pathway are responsive to leaf maturation. Overexpression of YUC1 in the yuc-1 D dominant mutant rescued the rooting defects caused by leaf maturation. In addition, YUC4 expression levels were also affected by circadian rhythms. The regenerative ability was reduced in both immature and mature mutant leaf explants from the new wuschel-related homeobox 11-3(wox11-3) and wox12-3 mutant alleles created by the CRISPR/Cas9 method. Overall, the transcriptome and genetic data, together with the auxin concentration analysis, indicate that the ability to upregulate auxin levels upon detachment may be reduced during leaf maturation. Thus, multiple developmental and environmental signals may converge to control auxin accumulation, which affects the efficiency of the WOX11/12-mediated DNRR from leaf explants. | Jing Pan Fei Zhao Guifang Zhang Yu Pan Lijun Sun Ning Bao Peng Qin Lyuqin Chen Jie Yu Yijing Zhang Lin Xu | 2019 | Journal of Genetics and Genomics2019，46，3： | 2 |

| 6 | Hybridization induced ion-barrier effect for the label-free and sensitive electrochemical sensing of Hepatocellular Carcinoma biomarker of miRNA-122显示文摘A label-free and sensitive electrochemical biosensing strategy for a hepatocellular carcinoma biomarker of miRNA-122 has been proposed based on hybridization induced ion-barrier effect on the electroactive sensing interface.First,a bifunctional electroactive electrode with the nanocomposite of Prussian blue(PB)and gold nanoparticles(AuNPs)was prepared through a two-step electrodeposition process.The PB endows the electrode excellent K^(+)-dependent voltammetric signal and the AuNPs act as the matrix for the self-assembly immobilization of the thiolated probe DNA.Upon specific hybridization of probe DNA with the target miRNA-122,the formed double duplex induced the ion-barrier effect,which blocked the diffusion of the K^(+)from the bulk solution to the electrode surface.As a result,the voltammetric signal of the PB on the electrode was surpressed,and thus the target miRNA-122 was monitored.The sensing assay showed that the miRNA-122 could be analyzed in the concentration range from 0.1 fmol/L to 1.0 nmol/L,with a detection limit of 0.021 fmol/L.The practical applicability of the biosensor was also verified by the spiking serum assay. | Feng Gao Yaru Chu Yijing Ai Weiqiang Yang Zhenyu Lin Qingxiang Wang | 2021 | Chinese Chemical Letters2021，32，7： | 0 |
| 7 | Performance Comparison of Computational Methods for the Prediction of the Function and Pathogenicity of Non-coding Variants显示文摘Non-coding variants in the human genome significantly influence human traits and complex diseases via their regulation and modification effects.Hence,an increasing number of computational methods are developed to predict the effects of variants in human non-coding sequences.However,it is difficult for inexperienced users to select appropriate computational methods from dozens of available methods.To solve this issue,we assessed 12 performance metrics of 24 methods on four independent non-coding variant benchmark datasets:(1)rare germline variants from clinical relevant sequence variants(ClinVar),(2)rare somatic variants from Catalogue Of Somatic Mutations In Cancer(COSMIC),(3)common regulatory variants from curated expression quantitative trait locus(eQTL)data,and(4)disease-associated common variants from curated genomewide association studies(GWAS).All 24 tested methods performed differently under various conditions,indicating varying strengths and weaknesses under different scenarios.Importantly,the performance of existing methods was acceptable for rare germline variants from ClinVar with the area under the receiver operating characteristic curve(AUROC)of 0.4481–0.8033 and poor for rare somatic variants from COSMIC(AUROC=0.4984–0.7131),common regulatory variants from curated eQTL data(AUROC=0.4837–0.6472),and disease-associated common variants from curated GWAS(AUROC=0.4766–0.5188).We also compared the prediction performance of 24 methods for non-coding de novo mutations in autism spectrum disorder,and found that the combined annotation-dependent depletion(CADD)and context-dependent tolerance score(CDTS)methods showed better performance.Summarily,we assessed the performance of 24 computational methods under diverse scenarios,providing preliminary advice for proper tool selection and guiding the development of new techniques in interpreting non-coding variants. | Zheng Wang Guihu Zhao Bin Li Zhenghuan Fang Qian Chen Xiaomeng Wang Tengfei Luo Yijing Wang Qiao Zhou Kuokuo Li Lu Xia Yi Zhang Xun Zhou Hongxu Pan Yuwen Zhao Yige Wang Lin Wang Jifeng Guo Beisha Tang Kun Xia Jinchen Li | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 0 |
| 8 | Semi-global weighted output average tracking of discrete-time heterogeneous multi-agent systems subject to input saturation and external disturbances显示文摘In this paper,we revisit the semi-global weighted output average tracking problem for a discrete-time multi-agent system subject to input saturation and external disturbances.The multi-agent system consists of multiple heterogeneous linear systems as leader agents and multiple heterogeneous linear systems as follower agents.We design both the state feedback and output feedback control protocols for each follower agent.In particular,a distributed state observer is designed for each follower agent that estimates the state of each leader agent.In the output feedback case,state observer is also designed for each follower agent to estimate its own state.With these estimates,we design low gain-based distributed control protocols,parameterized in a scalar low gain parameter.It is shown that,for any bounded set of the initial conditions,these control protocols cause the follower agents to track the weighted average of the outputs of the leader agents as long as the value of the low gain parameter is tuned sufficiently small.Simulation results illustrate the validity of the theoretical results. | Qilin Song Yuanlong Li Yijing Xie Zongli Lin | 2023 | Control Theory and Technology2023，21，3： | 0 |
| 9 | Prenatal Diagnosis of a Giant Epignathus in the Second Trimester and Immediate Successful Management at Birth:A Case Report显示文摘Epignathus is an extremely rare congenital oropharyngeal teratoma.Here,we report a case of epignathus without intracranial extension in a fetus.The mass was first found by ultrasonography at 22 gestational weeks.Serial ultrasound examinations and magnetic resonance imaging confirmed that the fetus had neither central nervous system involvement nor abnormal nose or tooth.The baby was delivered at 37 weeks and six days of gestation via cesarean section set up for ex-utero intrapartum treatment.The postnatal pathologic examination confirmed the presence of mature tissues predominantly containing ectopic central nervous tissue,osseous tissue,and bronchial mucosal tissue.Most cases of epignathus are associated with malformation and death.Ultrasound and magnetic resonance imaging prenatal assessments are very important to facilitate counseling and understand prognosis.In conclusion,the ex-utero intrapartum treatment procedure is a good approach to improve the survival of infants with epignathus. | Xiaoyu Hu Yijing Chu Yunqing Chen Min Zhao Xiaofei Wang Lin Xu | 2023 | Maternal-Fetal Medicine2023，5，2： | 0 |
| 10 | The neuroprotection of electro-acupuncture via the PGC-1α/TFAM pathway in transient focal cerebral ischemia rats显示文摘ATP depletion is one of the pathological bases in cerebral ischemia.Electro-acupuncture(EA)is widely used in clinical practice for ischemia.However,the mechanism of EA remains unclear.The purpose of this study was to investigate whether EA could activate the AMPK/PGC-1α/TFAM signaling pathway and,consequently,increase the preservation of ATP in rats with ischemia.In this study,48 rats were randomly divided into four groups as a sham-operation control group(sham group),a middle cerebral artery occlusion group(MCAO group),an EA group,and an EA group blocked by the AMPK inhibitor compound C(EA+CC group)(N=12/group).The rats of the EA group and EA+CC group received the EA treatment for 7 days.The rats that belonged in the two remaining groups were only grasped in the same condition.Then,their brain tissues were collected for further detection.When compared with other groups,EA significantly reduced neurological deficits score and increased motor function.The cerebral infarction volume was significantly reduced in the EA group according to TTC staining.With western blot,we found that EA improved the ratio of p-AMPKα/AMPKα(P<0.05),however,there is no difference between the MCAO group and sham group(P>0.05).In addition,EA also increased the expression of PGC-1αand TFAM(all P<0.05).By Elisa,we observed that EA increased the preservation of ATP(P<0.05)and mitochondrial respiratory enzymes,including Complex I(P<0.05),Complex IV(P<0.05),but not Complex III(P>0.05).In summary,we conclude that EA may protect against ischemic damage in MCAO rats,improve the preservation of ATP and mitochondrial respiratory enzymes.This effect may be positively regulated by the activation of the PGC-1α/TFAM signaling pathway. | LUPING YANG YIJING JIANG XIAOQIAN YE YONGMEI YOU LING LIN JING LIAN JUAN LI SHANLI YANG XIEHUA XUE | 2022 | BIOCELL2022，46，1： | 0 |
| 11 | Transcriptional landscapes of de novo root regeneration from detached Arabidopsis leaves revealed by time-lapse and single-cell RNA sequencing analyses显示文摘Detached Arabidopsis thaliana leaves can regenerate adventitious roots,providing a platformfor studying de novo root regeneration(DNRR).However,the comprehensive transcriptional framework of DNRR remains elusive.Here,we provide a high-resolution landscape of transcriptome reprogramming from wound response to root organogenesis in DNRR and show key factors involved in DNRR.Time-lapse RNA sequencing(RNA-seq)of the entire leaf within 12 h of leaf detachment revealed rapid activation of jasmonate,ethylene,and reactive oxygen species(ROS)pathways in response towounding.Genetic analyses confirmed that ethylene andROSmay serve as wound signals to promoteDNRR.Next,time-lapse RNA-seq within 5 d of leaf detachment revealed the activation of genes involved in organogenesis,wound-induced regeneration,and resource allocation in the wounded region of detached leaves during adventitious rooting.Genetic studies showed that BLADE-ON-PETIOLE1/2,which control aboveground organs,PLETHORA3/5/7,which control root organogenesis,and ETHYLENE RESPONSE FACTOR115,which controlswound-induced regeneration,are involved in DNRR.Furthermore,single-cell RNA-seq data revealed gene expression patterns in thewounded region of detached leaves during adventitious rooting.Overall,our study not only provides transcriptome tools but also reveals key factors involved in DNRR from detached Arabidopsis leaves. | Wu Liu Yuyun Zhang Xing Fang Sorrel Tran Ning Zhai Zhengfei Yang Fu Guo Lyuqin Chen Jie Yu Madalene SIson Teng Zhang Lijun Sun Hongwu Bian Yijing Zhang Li Yang Lin Xu | 2022 | Plant Communications2022，3，4： | 0 |
| 12 | Virtual Power Plants for Grid Resilience: A Concise Overview of Research and Applications显示文摘The power grid is undergoing a transformation from synchronous generators(SGs) toward inverter-based resources(IBRs). The stochasticity, asynchronicity, and limited-inertia characteristics of IBRs bring about challenges to grid resilience. Virtual power plants(VPPs) are emerging technologies to improve the grid resilience and advance the transformation. By judiciously aggregating geographically distributed energy resources(DERs) as individual electrical entities, VPPs can provide capacity and ancillary services to grid operations and participate in electricity wholesale markets. This paper aims to provide a concise overview of the concept and development of VPPs and the latest progresses in VPP operation, with the focus on VPP scheduling and control. Based on this overview, we identify a few potential challenges in VPP operation and discuss the opportunities of integrating the multi-agent system(MAS)-based strategy into the VPP operation to enhance its scalability, performance and resilience. | Yijing Xie Yichen Zhang Wei-Jen Lee Zongli Lin Yacov A.Shamash | 2024 | IEEE/CAA Journal of Automatica Sinica2024，11，2： | 0 |
| 13 | Two-Stage Edge-Side Fault Diagnosis Method Based on Double Knowledge Distillation显示文摘With the rapid development of the Internet of Things(IoT),the automation of edge-side equipment has emerged as a significant trend.The existing fault diagnosismethods have the characteristics of heavy computing and storage load,and most of them have computational redundancy,which is not suitable for deployment on edge devices with limited resources and capabilities.This paper proposes a novel two-stage edge-side fault diagnosis method based on double knowledge distillation.First,we offer a clustering-based self-knowledge distillation approach(Cluster KD),which takes the mean value of the sample diagnosis results,clusters them,and takes the clustering results as the terms of the loss function.It utilizes the correlations between faults of the same type to improve the accuracy of the teacher model,especially for fault categories with high similarity.Then,the double knowledge distillation framework uses ordinary knowledge distillation to build a lightweightmodel for edge-side deployment.We propose a two-stage edge-side fault diagnosismethod(TSM)that separates fault detection and fault diagnosis into different stages:in the first stage,a fault detection model based on a denoising auto-encoder(DAE)is adopted to achieve fast fault responses;in the second stage,a diverse convolutionmodel with variance weighting(DCMVW)is used to diagnose faults in detail,extracting features frommicro andmacro perspectives.Through comparison experiments conducted on two fault datasets,it is proven that the proposed method has high accuracy,low delays,and small computation,which is suitable for intelligent edge-side fault diagnosis.In addition,experiments show that our approach has a smooth training process and good balance. | Yang Yang Yuhan Long Yijing Lin Zhipeng Gao Lanlan Rui Peng Yu | 2023 | Computers, Materials & Continua2023，76，9： | 0 |
| 14 | Copper(Ⅱ) ions-immobilized virus-like hollow covalent organic frameworks for highly efficient capture and sensitive analysis of amyloid beta-peptide 1–42 by MALDI-MS显示文摘Amyloid beta-peptide 1-42(Aβ1-42)is one of the biomarkers of Alzheimer's disease,and its selective capture and quantitative detection are important for diagnosis and treatment of Alzheimer's disease.Herein,copper(Ⅱ)ions-immobilized virus-like hollow covalent organic frameworks(V-HCOFs@Cu^(2+))were synthesized by a facile approach.The as-prepared V-HCOFs@Cu^(2+)showed unique morphology,ultra-high specific surface(2552 m^(2)/g),uniform mesoporous structure(3.2 nm),superior chemical stability and abundant binding sites.Based on these excellent properties,the V-HCOFs@Cu^(2+)could be adopted as an ideal enrichment probe for highly efficient capture of Aβ1-42,exhibiting high adsorption capacity(320 mg/g),and fast adsorption equilibration time(3 min).In addition,an attractive approach of the V-HCOFs@Cu^(2+)-based matrix-assisted laser desorption/ionization mass spectrometry(MALDI-MS)was developed for the rapid screening and quantitative analysis of Aβ1-42 in human serum by using C-peptide as an internal standard,which exhibited low limit of detection(LOD,0.2 fmol/μL),and satisfactory recovery.This work provides an alternative solution for enrichment of biomarkers and also offers the potential applications of COFs in clinical analysis. | Wende Ma Chao Zhong Juan Lin Zhuling Chen Guorong Li Wei Tong Yijing Wu Lan Zhang Zian Lin | 2022 | Chinese Chemical Letters2022，33，12： | 0 |
| 15 | Brain-targeted drug delivery assisted by physical techniques and its potential applications in traditional Chinese medicine显示文摘The blood-brain barrier(BBB)constitutes a major obstacle to effective delivery of drugs to the brain.Recent technological advances have led to improvements in brain-targeted drug delivery.In this review,we summarize existing technologies for efficient drug delivery across the BBB.We discuss the mechanisms of current BBB-based drug delivery strategies and introduce prospects for application in braint-argeted delivery of traditional Chinese medicine.We highlight the use of physical techniques for brain-targeted drug delivery,including electroporation,ultrasound,magnetophoresis,microneedles,microwaves,and laser.The characteristics of these techniques and relevant studies employing these approaches are discussed.In general,microneedles,lasers,ultrasound,electroporation,magnetophoresis,and microwaves are effective for drug delivery across the BBB.Notably,the synergistic effects of multiple approaches are superior to the additive effects of each technique in isolation.Our review provides guidance for the practical application of brain-targeted drug delivery techniques in an efficient and safe manner. | Yunbo Sun Lina Du Meiyan Yang Qi Li Xueli Jia Qian Li Lin Zhu Yuanyuan Zhang Yijing Liu Shuchen Liu | 2021 | Journal of Traditional Chinese Medical Sciences2021，8，3： | 0 |
| 16 | Kondo resonance assisted thermoelectric transport through strongly correlated quantum dots显示文摘We theoretically studied the thermoelectric transport properties of a strongly correlated quantum dot system in the presence of the Kondo effect based on accurate numerical evaluations using the hierarchical equations of motion approach.The thermocurrent versus gate voltage shows a distinct sawtooth line-shape at high temperatures.In particular,the current changes from positive(hole charge)to negative(particle charge)in the electron number N=1 region due to the Coulomb blockade effect.However,at low temperatures,where the Kondo effect occurs,the thermocurrent’s charge polarity reverses,along with a significantly enhanced magnitude.As anticipated,the current sign can be analyzed by the occupation difference between particle and hole.Moreover,the characteristic turnover temperature can be further defined at which the influences of the Coulomb blockade and Kondo resonance are in an effective balance.Remarkably,the identified characteristic turnover temperature,as a function of the Coulomb interaction and dot-lead coupling,possessed a much higher value than the Kondo temperature.When a magnetic field is applied,a spin-polarized thermocurrent can be obtained,which could be tested in future experiments. | YongXi Cheng ZhenHua Li JianHua Wei HongGang Luo HaiQing Lin YiJing Yan | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，9： | 0 |
