| 1 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
| 2 | The Role of MicroRNAs in Neural Stem Cells and Neurogenesis显示文摘Neural stem cells give rise to neurons through the process of neurogenesis,which includes neural stem cell proliferation,fate determination of new neurons,as well as the new neuron's migration,maturation and integration.Currently,neurogenesis is divided into two phases:embryonic and adult phases.Embryonic neurogenesis occurs at high levels to form the central nervous system.Adult neurogenesis has been consistently identified only in restricted regions and occurs at low levels.As the basic process for embryonic neurodevelopment and adult brain maintenance,neurogenesis is tightly regulated by many factors and pathways.MicroRNA,short non-coding RNA that regulates gene expression at the post-transcriptional level,appears to be involved in multiple steps of neurogenesis.This review summarizes the emerging role of microRNAs in regulating embryonic and adult neurogenesis,with a particular emphasis on the proliferation and differentiation of neural stem cells. | Fen Ji Xiaohui Lv Jianwei Jiao | 2013 | Journal of Genetics and Genomics2013，40，2： | 11 |
| 3 | In-situ structural evolution analysis of Zr-doped Na_(3)V_(2)(PO_(4))_(2)F_(3) coated by N-doped carbon layer as high-performance cathode for sodium-ion batteries显示文摘With great superiorities in energy density,rate capability and structural stability,Na_(3)V_(2)(PO_(4))_(2) F_(3)(NVPF)has attracted much attentions as cathode of sodium ion battery(SIB),but it also faces challenges on its poor intrinsic electronic conductivity and the controversial de/sodiation mechanism.Herein,a series of Zr-doped NVPF coated by N-doped carbon layer(~5 nm in thickness,homogenously)materials are fabricated by a sol-gel method,and the optimized heteroatom-doping amounts of Zr and N doping improve intrinsic properties on enlarging lattice distance and enhancing electronic conductivity,respectively.Specifically,among all samples of Na_(3) V_(2-x)Zr_(x)(PO_(4))_(2) F_(3)/NC(NVPF-Zr-x/NC,x=0,0.01,0.02,0.05,and 0.1),the optimized electrode of NVPF-Zr-0.02/NC delivers high reversible capacities(119.2 mAh g^(-1) at0.5 C),superior rate capability(98.1 mA h g^(-1) at 20 C)and excellent cycling performance.The structural evolution of NVPF-Zr-0.02/NC electrode,in-situ monitored by X-ray diffractometer,follows a step-wise Na-extraction/intercalation mechanism with reversible multi-phase changes,not just a solid-solutionreaction one.Full cells of NVPF-Zr-0.02/NC//hard carbon demonstrate high capacity(99.8 mA h g^(-1) at 0.5 C),high out-put voltage(3.5 V)and good cycling stability.This work is favorable to accelerate the development of high-performance cathode materials and explore possible redox reaction mechanisms of SIBs. | Chuan Guo Jianwei Yang Zhiyuan Cui Shuo Qi Qianqian Peng Weiwei Sun Li-Ping Lv Yi Xu Yong Wang Shuangqiang Chen | 2022 | Journal of Energy Chemistry2022，31，2： | 5 |
| 4 | Polarization-enhanced AlGaN solar-blind ultraviolet detectors显示文摘AlGaN solar-blind ultraviolet detectors have great potential in many fields,although their performance has not fully meet the requirements until now.Here,we proposed an approach to utilize the inherent polarization effect of AlGaN to improve the detector performance.AlGaN heterostructures were designed to enhance the polarization field in the absorption layer,and a high built-in field and a high electron mobility conduction channel were formed.As a result,a high-performance solar-blind ultraviolet detector with a peak responsivity of 1.42 A/W at 10 V was achieved,being 50 times higher than that of the nonpolarization-enhanced one.Moreover,an electron reservoir structure was proposed to further improve the performance.A higher peak responsivity of 3.1 A/W at30 V was achieved because the electron reservoir structure could modulate the electron concentration in the conduction channel.The investigation presented here provided feasible approaches to improve the performance of the AlGaN detector by taking advantage of its inherent property. | Ke Jiang Xiaojuan Sun Zi-Hui Zhang Jianwei Ben Jiamang Che Zhiming Shi Yuping Jia Yang Chen Shanli Zhang Wei Lv Dabing Li | 2020 | Photonics Research2020，8，7： | 3 |
| 5 | The Msi1-mTOR pathway drives the pathogenesis of mammary and extramammary Paget’s disease显示文摘Mammary and extramammary Paget’s Diseases(PD)are a malignant skin cancer characterized by the appearance of Paget cells.Although easily diagnosed,its pathogenesis remains unknown.Here,single-cell RNA-sequencing identified distinct cellular states,novel biomarkers,and signaling pathways—including mTOR,associated with extramammary PD.Interestingly,we identified MSI1 ectopic overexpression in basal epithelial cells of human PD skin,and show that Msi1 overexpression in the epidermal basal layer of mice phenocopies human PD at histopathological,single-cell and molecular levels.Using this mouse model,we identified novel biomarkers of Paget-like cells that translated to human Paget cells.Furthermore,single-cell trajectory,RNA velocity and lineage-tracing analyses revealed a putative keratinocyte-to-Paget-like cell conversion,supporting the in situ transformation theory of disease pathogenesis.Mechanistically,the Msi1-mTOR pathway drives keratinocyte-Paget-like cell conversion,and suppression of mTOR signaling with Rapamycin significantly rescued the Paget-like phenotype in Msi1-overexpressing transgenic mice.Topical Rapamycin treatment improved extramammary PD-associated symptoms in humans,suggesting mTOR inhibition as a novel therapeutic treatment in PD. | Yongli Song Christian F.Guerrero-Juarez Zhongjian Chen Yichen Tang Xianghui Ma Cong Lv Xueyun Bi Min Deng Lina Bu Yuhua Tian Ruiqi Liu Ran Zhao Jiuzhi Xu Xiaole Sheng Sujuan Du Yeqiang Liu Yunlu Zhu Shi-jun Shan Hong-duo Chen Yiqiang Zhao Guangbiao Zhou Jianwei Shuai Fazheng Ren Lixiang Xue Zhaoxia Ying Xing Dai Christopher J.Lengner Bogi Andersen Maksim V.Plikus Qing Nie Zhengquan Yu-Show | 2020 | Cell Research2020，30，10： | 2 |
| 6 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |

| 8 | Sequential separation of Cu(Ⅱ)/Ni(Ⅱ)/Fe(Ⅱ)from strong-acidic pickling wastewater with a two-stage process based on a bi-pyridine chelating resin显示文摘A self-synthesized bi-pyridine chelating resin(PAPY)could separate Cu(Ⅱ)/Ni(Ⅱ)/Fe(Ⅱ)sequentially from strong-acidic pickling wastewater by a two-stage p H-adjusted process,in which Cu(Ⅱ),Ni(Ⅱ),and Fe(Ⅱ)were successively preferred by PAPY.In the first stage(p H 1.0),the separation factor of Cu(Ⅱ)over Ni(Ⅱ)reached 61.43 in Cu(Ⅱ)-Ni(Ⅱ)-Fe(Ⅱ)systems.In the second stage(p H 2.0),the separation factor of Ni(Ⅱ)over Fe(Ⅱ)reached 92.82 in Ni(Ⅱ)-Fe(Ⅱ)systems.Emphasis was placed on the selective separation of Cu(Ⅱ)and Ni(Ⅱ)in the first-stage.The adsorption amounts of Cu(Ⅱ)onto PAPY were 1.2 mmol/g in the first stage,while those of Ni(Ⅱ)and Fe(Ⅱ)were lower than 0.3 mmol/g.Cu(Ⅱ)adsorption was hardly affected by Ni(Ⅱ)with the presence of dense Fe(Ⅱ),but Cu(Ⅱ)inhibited Ni(Ⅱ)adsorption strongly.Part of preloaded Ni(Ⅱ)could be replaced by Cu(Ⅱ)based on the replacement effect.Compared with the absence of Fe(Ⅱ),dense Fe(Ⅱ)could obviously enhance the separation of Cu(Ⅱ)-Ni(Ⅱ).More than 95.0%of Cu(Ⅱ)could be removed in the former 240 BV(BV for bed volume of the adsorbent)in the fixed-bed adsorption column process with the flow rate of 2.5 BV/h.As proved by X-ray photoelectron spectrometry(XPS)and density functional theory(DFT)analyses,Cu(Ⅱ)exerted a much stronger deprotonation and chelation ability toward PAPY than Ni(Ⅱ)and Fe(Ⅱ).Thus,the work shows a great potential in the separation and purification of heavy metal resources from strong-acidic pickling wastewaters. | Yingzhi Lv Lidan Zong Zicheng Liu Jianwei Du Fenghe Wang Yanhong Zhang Chen Ling Fuqiang Liu | 2021 | Chinese Chemical Letters2021，32，9： | 1 |
| 9 | Paleoenvironment controls on organic matter accumulation in transitional shales from the eastern Ordos Basin,China显示文摘To investigate the paleoenvironmental controls on organic matter accumulation of Upper Paleozoic shales in the eastern Ordos Basin,China,26 shale samples were collected from two wells drilled into the Shanxi and Taiyuan Formations.The total organic carbon(TOC)content,mineral compositions and elemental geochemistry of the samples were analyzed.Quartz(35.42%)and clay minerals(48.34%)are the dominant minerals and trace elements(Li,Cs,Cu,V,Co,and Cr)are commonly enriched in the shale samples compared to the Upper Continental Crust.C-values(ranging from 0.2 to 4.5),chemical indices of weathering(CIW)values(48.82 to 99.11),and Sr/Cu ratios(1.00 to 11.05)suggest that the paleoclimate was humid in the study area during the Late Paleozoic.Elemental redox indices(e.g.,Al_(2)O_(3)/(Al_(2)O_(3)+Fe_(2)O_(3)),V/Cr,Ni/Co,V/(V+Ni)and U/Th)indicate a dysoxic to oxic paleoenvironment characterized by transi-tional sedimentary deposits in a continental margin setting.In addition,chemical index of alteration(CIA,ranging from 77.92%to 98.36%)and CIW(89.19%to 99.11%)values suggest that there was intense chemical weathering in the study area,while the Al_(2)O_(3)-CaO^(*)+Na_(2)O-K_(2)O(A-CN-K)ternary diagram demonstrates that the shales were not subjected to potassium metasomatism during diagen-esis.Al_(2)O_(3)/TiO_(2)and TiO_(2)/Zr ratios,as well as REE characteristics suggest a felsic source rocks and discount seawater as an REE source.Ce anomalies indicate an oxic environment with terrigenous input during black shale deposition,and LREE enrichment with negative Eu anomalies suggests that both shale formations were affected by detrital input rather than hydrothermal fluids.The correlation of TOC(ranging from 1.10%to 6.39%,with an average of 2.77%)with trace elemental redox indices(Sr/Cu,Sr/Ba,V/Cr,and U/Th)indicates that a warm-humid,dysoxic to oxic environment preserved much of the organic matter. | Jianwei LV Songhang ZHANG Ning YANG Chunbo FU Xinlu YAN Yang LI | 2021 | Frontiers of Earth Science2021，15，4： | 1 |
| 10 | A framework for the responsible reform of the 14-day rule in human embryo research显示文摘Ever since the world's first'test-tube'baby was bom in 1978,the use of human embryos in research has become highly controversial ethically and thus created a significant challenge for jurisdictions,especially in Europe and the United States,to determine the relevant policies(Poplawski and Gilelt,1991). | Yaojin Peng Jianwei Lv Zhenyu Xiao Lulu Ding Qi Zhou | 2022 | Protein & Cell2022，13，8： | 0 |
| 11 | Tunable piezoelectric and ferroelectric responses of Al1-xScxN:The role of atomic arrangement显示文摘In this study,we present first-principles investigations of the atomic structure of Al_(1-x)Sc_(x)N and its influence on its piezoelectric and ferroelectric properties.The unbiased structure searching revealed that Al_(1-x)Sc_(x)N with phase separation feature,where Al N and Sc N form a layered structure with different symmetries,is more stable than the corresponding wurtzite structure.The piezoelectric response of Al_(1-x)Sc_(x)N is strongly dependent on the atomic arrangements;in particular,Al_(0.5)Sc_(0.5)N with a wurtzite structure exhibits a large positive e33of 4.79 C/m^(2),whereas Al_(0.5)Sc_(0.5)N with a phase separation structure exhibits a negative e33of-0.67 C/m^(2).Moreover,the ferroelectric switching of Al_(1-x)Sc_(x)N demonstrated two distinct pathways for the wurtzite and phase separation structures,and the spontaneous polarization thus calculated exhibits entirely different values.Accordingly,we demonstrated that Al_(1-x)Sc_(x)N with a phase separation structure exhibits a low polarization switching barrier of 0.15 e V/f.u.and a large spontaneous polarization of-0.77 C/m^(2);thus,it can serve as a novel Al_(1-x)Sc_(x)N-based ferroelectric material.As the dipoles in Al_(1-x)Sc_(x)N with a phase separation structure are localized in the AlN region,they are individually switchable at no domain wall energy cost and are stable against extrinsic effects. | Hang Zang Zhiming Shi Mingrui Liu Yuping Jia Ke Jiang Jianwei Ben Yang Chen Shunpeng Lv Xiaojuan Sun Dabing Li | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，7： | 0 |
| 12 | Development and validation of simple sequence repeat markers from Arachis hypogaea transcript sequences显示文摘Simple sequence repeats(SSRs) are important molecular markers for assessing genetic diversity in Arachis hypogaea L. and many other crops and constructing genetic linkage maps for important agricultural traits. In this study, 29,357 potential SSRs were identified in 22,806 unigenes assembled from A. hypogaea transcript sequences. Of these unigenes, 1883 and 4103 were annotated and assigned in Kyoto Encyclopedia of Genes and Genomes Orthology and Eukaryotic Orthologous Groups databases, respectively. Among the SSR motifs, mono-(19,065; 64.94%) and trinucleotide(5033; 17.14%) repeats were the most common, and the three most dominant motifs were A/T(18,358; 62.54%), AG/CT(2804;9.55%), and AAG/CTT(1396; 4.76%). Polymerase chain reaction(PCR) primer pairs were designed for 4340 novel SSR markers and 210 new SSRs were validated using 24 A. hypogaea varieties. Of the 210, 191(91%) yielded PCR products, with 37(18%) identifying polymorphisms. The 37 polymorphic SSR markers detected 146 alleles(2–10 alleles per locus), and the average polymorphic information content was 0.403(with a range of 0.077 to0.819). The new SSRs enrich the current marker resources for A. hypogaea and may also be useful for genetic diversity analysis, functional genomics research, and molecular breeding. | Houmiao Wang Yong Lei Liying Yan Liyun Wan Yan Cai Zefeng Yang Jianwei Lv Xiaojie Zhang Chenwu Xu Boshou Liao | 2018 | The Crop Journal2018，6，2： | 0 |
| 13 | Cancer cell employs a microenvironmental neural signal transactivating nucleus-mitochondria coordination to acquire stemness显示文摘Cancer cell receives extracellular signal inputs to obtain a stem-like status,yet how tumor microenvironmental(TME)neural signals steer cancer stemness to establish the hierarchical tumor architectures remains elusive.Here,a pan-cancer transcriptomic screening for 10852 samples of 33 TCGA cancer types reveals that cAMP-responsive element(CRE)transcription factors are convergent activators for cancer stemness.Deconvolution of transcriptomic profiles,specification of neural markers and illustration of norepinephrine dynamics uncover a bond between TME neural signals and cancer-cell CRE activity.Specifically,neural signal norepinephrine potentiates the stemness of proximal cancer cells by activating cAMP-CRE axis,where ATF1 serves as a conserved hub.Upon activation by norepinephrine,ATF1 potentiates cancer stemness by coordinated trans-activation of both nuclear pluripotency factors MYC/NANOG and mitochondrial biogenesis regulators NRF1/TFAM,thereby orchestrating nuclear reprograming and mitochondrial rejuvenating.Accordingly,single-cell transcriptomes confirm the coordinated activation of nuclear pluripotency with mitochondrial biogenesis in cancer stem-like cells.These findings elucidate that cancer cell acquires stemness via a norepinephrine-ATF1 driven nucleus-mitochondria collaborated program,suggesting a spatialized stemness acquisition by hijacking microenvironmental neural signals. | Bin He Rui Gao Shasha Lv Ailin Chen Junxiu Huang Luoxuan Wang Yunxiu Feng Jiesi Feng Bing Liu Jie Lei Bing Deng Bin He Bai Cui Fei Peng Min Yan Zifeng Wang Eric W-F Lam Bilian Jin Zhiming Shao Yulong Li Jianwei Jiao Xi Wang Quentin Liu | 2023 | Signal Transduction and Targeted Therapy2023，8，8： | 0 |

| 15 | Universal chimeric Fcγreceptor T cells with appropriate affinity for IgG1 antibody exhibit optimal antitumor efficacy显示文摘Developing universal CARs with improved flexible targeting and controllable activities is urgently needed.While several studies have suggested the potential of CD16a in tandem with monoclonal antibodies to construct universal CAR-T cells,the weak affinity between them is one of the limiting factors for efficacy.Herein,we systematically investigated the impact of Fcγreceptor(FcγR)affinity on CAR-T cells properties by constructing universal CARs using Fcγreceptors with different affinities for IgG1 antibodies,namely CD16a,CD32a,and CD64.We demonstrated that the activities of these universal CAR-T cells on tumor cells could be redirected and regulated by IgG1 antibodies.In xenografted mice,64CAR chimeric Jurkat cells with the highest affinity showed significant antitumor effects in combination with herceptin in the HER2 low expression U251 MG model.However,in the CD20 high expression Raji model,64CAR caused excessive activation of CAR-T cells,which resulted in cytokine release syndrome(CRS)and the decline of antitumor activity,and 32CAR with a moderate affinity brought the best efficacy.Our work extended the knowledge about FcγR-based universal CAR-T cells and suggested that only the FcγRCAR with an appropriate affinity can offer the optimal antitumor advantages of CAR-T cells. | Wen Zhu Yang Wang Liangyin Lv Hui Wang Wenqiang Shi Zexin Liu Mingzhe Zhou Jianwei Zhu Huili Lu | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 0 |
| 16 | Synthesis and Surface Active Properties of Cyanuric Chloride-based Branched Surfactant显示文摘A series of novel branched sodium carboxylate surfactants were synthesized from cyanuric chloride, behera amine, alcohol amine and 1,4-Bis (3-aminopropyl) piperazine through seven steps, and the total yield is about 25%. The chemical structures of target products were confirmed by 1H NMR, 13C NMR, FT-IR and ESI-MS. Their critical micelle concentrations (CMC) were also determined by surface tension tests in the aqueous solutions at 22 ℃. The results showed that the CMC value of multi-carboxylate anionic surfactants decreased with the increase of hydroxyl. Additionally, the branched structure of end group can reduce surface tension more than straight-chain type, which was determined by γCMC. The decomposition temperature of the target compound was 250 ℃, which was also tested by TG/DTA curve. | Lv Jinge Lu Chunbin Yuan Cuili Han Jianwei Wang Limin | 2019 | China Detergent & Cosmetics2019，4，2： | 0 |
