| 2 | Single-cell transcriptomic atlas of primate cardiopulmonary aging显示文摘Aging is a major risk factor for many diseases,especially in highly prevalent cardiopulmonary comorbidities and infectious diseases including Coronavirus Disease 2019(COVID-19).Resolving cellular and molecular mechanisms associated with aging in higher mammals is therefore urgently needed.Here,we created young and old non-human primate single-nucleus/cell transcriptomic atlases of lung,heart and artery,the top tissues targeted by SARS-CoV-2.Analysis of cell type-specific aging-associated transcriptional changes revealed increased systemic inflammation and compromised virus defense as a hallmark of cardiopulmonary aging.With age,expression of the SARS-CoV-2 receptor angiotensin-converting enzyme 2(ACE2)was increased in the pulmonary alveolar epithelial barrier,cardiomyocytes,and vascular endothelial cells.We found that interleukin 7(IL7)accumulated in aged cardiopulmonary tissues and induced ACE2 expression in human vascular endothelial cells in an NF-κB-dependent manner.Furthermore,treatment with vitamin C blocked IL7-induced ACE2 expression.Altogether,our findings depict the first transcriptomic atlas of the aged primate cardiopulmonary system and provide vital insights into age-linked susceptibility to SARS-CoV-2,suggesting that geroprotective strategies may reduce COVID-19 severity in the elderly. | Shuai Ma Shuhui Sun Jiaming Li Yanling Fan Jing Qu Liang Sun Si Wang Yiyuan Zhang Shanshan Yang Zunpeng Liu Zeming Wu Sheng Zhang Qiaoran Wang Aihua Zheng Shuguang Duo Yang Yu Juan Carlos Izpisua Belmonte Piu Chan Qi Zhou Moshi Song Weiqi Zhang Guang-Hui Liu | 2021 | Cell Research2021，31，4： | 10 |
| 3 | Super-resolution fluorescence-assisted diffraction computational tomography reveals the threedimensional landscape of the cellular organelle interactome显示文摘The emergence of super-resolution(SR)fluorescence microscopy has rejuvenated the search for new cellular substructures.However,SR fluorescence microscopy achieves high contrast at the expense of a holistic view of the interacting partners and surrounding environment.Thus,we developed SR fluorescence-assisted diffraction computational tomography(SR-FACT),which combines label-free three-dimensional optical diffraction tomography(ODT)with two-dimensional fluorescence Hessian structured illumination microscopy.The ODT module is capable of resolving the mitochondria,lipid droplets,the nuclear membrane,chromosomes,the tubular endoplasmic reticulum,and lysosomes.Using dual-mode correlated live-cell imaging for a prolonged period of time,we observed novel subcellular structures named dark-vacuole bodies,the majority of which originate from densely populated perinuclear regions,and intensively interact with organelles such as the mitochondria and the nuclear membrane before ultimately collapsing into the plasma membrane.This work demonstrates the unique capabilities of SR-FACT,which suggests its wide applicability in cell biology in general. | Dashan Dong Xiaoshuai Huang Liuju Li Heng Mao Yanquan Mo Guangyi Zhang Zhe Zhang Jiayu Shen Wei Liu Zeming Wu Guanghui Liu Yanmei Liu Hong Yang Qihuang Gong Kebin Shi Liangyi Chen | 2020 | Light(Science & Applications)2020，9，1： | 7 |
| 4 | Single small molecule-assembled nanoparticles mediate efficient oral drug delivery显示文摘Oral drug delivery,which requires surviving the harsh environment in the gastrointestinal(Gl)tract and penetrating the intestinal epithelium,has not bee n achieved using simple formulatio n nan oparticles(NPs).Medici nal natural products(MNPs)have bee n widely used in traditi onal medicine for disease management through oral consumption.However,most pharmacologically active compounds within MNPs do not have the properties suitable for oral applicatio ns.We hypothesize that some MNPs contain n atural nano materials that can convert those compounds into oral formulations by forming NPs.After screening 66 MNPs,we identified five classes of small molecules that form NPs,many of which are capable of efficient drug encapsulation and Gl penetration.We show that one of them,dehydrotrametenolic acid(DTA),is capable of mediating oral delivery for effective disease treatment.We determined that DTA NPs assemble through hydrogen bonding and penetra怕the Gl tract via apical sodium-depe ndent bile acid tran sporter.Our study reveals a no vel class of single comp orient,small molecule-assembled NPs for oral drug delivery,and suggests a n ovel approach to modernizi ng MNPs through nano material discovery. | Xin Yang Chao Ma Zeming Chen Jun Liu Fuyao Liu Rongbin Xie Haitian Zhao Gang Deng Ann TChen Ningbo Gong Lei Yao Pengjian Zuo Kangkang Zhi Jiacheng Wang Xiaobin Gao Jing Wang Louzhen Fan Jiangbing Zhou | 2019 | Nano Research2019，12，10： | 4 |

| 6 | Micro-area Chemical Composition and Preserved P-T Evolution Trace of Phengite in Albite Gneiss from the Donghai Ultrahigh-Pressure Metamorphic Area,East China显示文摘Study of micro-area chemical compositions indicates that phengite in albite gneiss from hole ZK2304 of the Donghai region has evident compositional zoning. SiO2 and tetrahedrally coordinated Si contents decrease, and Al2O3, AlIV and AlVI contents increase gradually from core to rim. However, K2O, MgO and FeO contents basically remain unchanged from core to rim. According to P-T estimates obtained from geothermometers and barometers, combined with previous experimental data, the core belt (micro-area I) of phengite was formed at T=637-672℃ and P=1.55-1.73 GPa, and the transitional belt (micro-area II) of the phengite were formed at r=594-654℃ and P=1.35-1.45 GPa. Towards the rim belt (micro-area III), the temperature decreased slightly, but the pressure decreased rapidly with r=542-630℃ and P=1.12-1.19 GPa. The P-T evolution path recorded by the compositional zoning of phengite is characterized by significant near-isothermal decompression, revealing that the gneiss has. undergone | LIU Fulai ZHANG Zeming XU Zhiqin YANG Jingsui XU Huifen | 2000 | Acta Geologica Sinica(English Edition)2000，74，2： | 2 |
| 7 | From mandatory icebreaker guiding to a permission regime: changes to the new Russian legislation of the Northern Sea Route显示文摘This article focuses on two issues. The first concerns definitions of the Northern Sea Route(NSR) in old and new Russian legislation, and the second relates to Russian rules on icebreaker guiding. Based on a comprehensive comparative analysis of relevant Russian legal provisions enacted in 2013 and previous laws in this area, we offer the following conclusions.(1) Our legal analysis indicates that Russia's view of the NSR as a historical national transportation route has not changed. However, the new law redefines the scope and coverage of the NSR, which now comprises the internal waters, territorial sea, adjacent zone, and the exclusive economic zone of the Russian Federation. In fact, the new law resolves previous ambiguity regarding extension of the NSR boundary to the high seas.(2) Based on an analysis of the new rules on icebreaker guiding, the article concludes that NSR is transitioning from a mandatory icebreaker guiding regime into a permit regime. This is particularly evident in its provision of a concrete, practical, and predictable clause on permissible or impermissible conditions relating to independent navigation. According to the new rules, it is possible for foreign ships to undertake independent navigation in the NSR. The Russian NSR policy, therefore, appears to have changed significantly, and has future potential for opening the NSR up to the international community. | ZHANG Xia ZOU Leilei TU Jingfang QIAN Zongqi WANG Zeming YANG Huigen | 2014 | Advances in Polar Science2014，25，3： | 2 |
| 8 | Working-in-tandem mechanism of multi-dopants in enhancing electrocatalytic nitrogen reduction reaction performance of carbon- based materials显示文摘Developing carbon-based electrocatalysts with excellent N2 adsorption and activation capability holds the key to achieve highly efficient nitrogen reduction reaction(NRR)for reaching its practical application.Here,we report a highly active electrocatalyst--metal-free pyrrolic-N dominated N,S co-doped carbon(pyrr-NSC)for NRR.Based on theoretical and experimental results,it is confirmed that the N and S-dopants practice a working-in-tandem mechanism on pyrr-NSC,where the N-dopants are utilized to create electropositive C sites for enhancing N2 adsorption and the S-dopants are employed to induce electron backdonation for facilitating N2 activation.The synergistic effect of the pyrrolic-N and S-dopants can also suppress the irritating hydrogen evolution reaction,further boosting the NRR performance.This work gives an indication that the combination of two different dopants on electrocatalyst can enhance NRR performance by working in the two tandem steps-the adsorption and activation of N2 molecules,providing a new strategy for NRR electrocatalyst design. | Wenqing Zhang Keke Mao Jingxiang Low Hengjie Liu Yanan Bo Jun Ma Qiaoxi Liu Yawen Jiang Jiuzhong Yang Yang Pan Zeming Qi Ran Long Li Song Yujie Xiong | 2021 | Nano Research2021，14，9： | 2 |

| 11 | Variational PCA fusion for Pan-sharpening very high resolution imagery显示文摘The Pan-sharpening approach based on principle component analysis(PCA) is affected by severe spectral distortion. To address this problem, a new pan-sharpening model based on PCA and variational technique is proposed to construct the substitute image of the first principal component(PC1). The energy functional consists of three terms. The first term injects PC1 with the geometric structure of the panchromatic(Pan) image. The second term preserves the spectral pattern of the multi-spectral image in the merged result.And the third term guarantees the smoothness of the functional optimization solution. The fusion result is given by the minimum of the energy functional, which is computed with the gradient descend flow. The experiments on QuickBird and IKONOS datasets validate the effectiveness of the proposed model. Compared with the stateof-the-art pan-sharpening approaches, this model exhibits a better trade-off between improving spatial quality and preserving spectral signature of the MS image. | ZHOU ZeMing MA Ning LI YuanXiang YANG PingL ZHANG Peng LI YunYing | 2014 | Science China(Information Sciences)2014，57，11： | 1 |

| 14 | Ammonium Impacts on Vibrations of Hydroxyl and Lattice of Phengite at High Temperature and High Pressure显示文摘Dehydration in hydrous phases of the downgoing slab controls water release processes in subduction zones. Interplay between volatiles in hydrous minerals has complicated the previous knowledge of their dehydration. Phengite is an essential mineral carrying both hydrogen and nitrogen to the deep Earth. To further understand the link between nitrogen and dehydration process of phengite at an atomic level, we here carry out high temperature and high pressure vibrational spectroscopic investigations on hydroxyl and lattice of ammonium-bearing and ammonium-free phengites. The results show that heating to 800 oC hardly influences hydroxyl bonding strength, whereas pressure induces strengthening of hydrogen bonding until 10 GPa. Moreover, hydrogen transits between the sites with increasing temperature and pressure. The lattice modes soften with increasing temperature and stiffen under compression. Ammonium has no effect on hydroxyl bonding strength, but hinders hydrogen transition at high temperatures and high pressures. Ammonium does not influence the lattice at high pressures either, but delays softening of the lattice at high temperatures. These data unveil behavior of hydroxyl and lattice in phengite at high temperature and high pressure, and also evaluate ammonium impacts, shedding new lights on dehydration processes of phengite during subduction. | Weihua Huang Yan Yang Zeming Qi Wendi Liu Zhongping Wang Yan Liu Qunke Xia | 2021 | Journal of Earth Science2021，32，5： | 0 |
| 15 | Highly Improved Electrochemical Performances of the Nanocrystalline and Amorphous Mg_2Ni-type Alloys by Substituting Ni with M (M=Cu,Co,Mn)显示文摘The element Ni in the Mg_2Ni alloy is partially substituted by M(M = Cu, Co, Mn) in order to ameliorate the electrochemical hydrogen storage performances of Mg_2Ni-type electrode alloys. The nanocrystalline and amorphous Mg_(20)Ni_(10-x)M_x(M = None, Cu, Co, Mn; x = 0-4) alloys were prepared by melt spinning. The effects of the M(M = Cu, Co, Mn) content on the structures and electrochemical hydrogen storage characteristics of the as-cast and spun alloys were comparatively studied. The analyses by XRD, SEM and HRTEM reveal that all the as-cast alloys have a major phase of Mg_2Ni but the M(M = Co, Mn) substitution brings on the formation of some secondary phases, MgCo_2 and Mg for the(M = Co) alloy, and Mn Ni and Mg for the(M = Mn) alloy. Besides, the as-spun(M = None, Cu) alloys display an entirely nanocrystalline structure, whereas the as-spun(M = Co, Mn) alloys hold a nanocrystalline/amorphous structure, suggesting that the substitution of M(M = Co, Mn) for Ni facilitates the glass formation in the Mg_2Ni-type alloys. The electrochemical measurements indicate that the variation of M(M = Cu, Co, Mn) content engenders an obvious effect on the electrochemical performances of the as-cast and spun alloys. To be specific, the cyclic stabilities of the alloys augment monotonously with increasing M(M = Cu, Co, Mn) content, and the capacity retaining rate(S20) is in an order of(M = Cu) >(M = Co) >(M = Mn) >(M = None) for x≤1 but changes to(M = Co) >(M = Mn) >(M = Cu) >(M = None) for x≥2. The discharge capacities of the as-cast and spun alloys always grow with the rising of M(M = Co, Mn) content but first mount up and then go down with increasing M(M = Cu) content. Whatever the M content is, the discharge capacities are in sequence:(M = Co) >(M = Mn) >(M = Cu) >(M = None). The high rate discharge abilities(HRDs) of all the alloys grow clearly with rising M(M = Cu, Co) content except for(M = Mn) alloy, whose HRD has a maximum value with varying M(M = Mn) content. Furthermore, for the as-cast alloys, the HRD is in order of(M = Co) >(M = Mn) >(M = Cu) >(M = None), while for the as-spun(20 m·s^(-1)) alloys, it changes from(M = Co) >(M = Mn) >(M = Cu) >(M = None) for x = 1 to(M = Cu) >(M = Co) >(M = None) >(M = Mn) for x = 4. | 张羊换 YUAN Zeming YANG Tai ZHAI Tinging LIU Zhuocheng GUO Shihai | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，3： | 0 |

| 17 | Research and Analysis of Regional Ecological Positioning in Planning Environmental Impact Assessment显示文摘The regional ecological positioning of one area is based on the region’s ecological orientation by the country or a larger region.Combined with the region’s natural geographical features,ecological background,main ecological problems,regional ecological structure,pattern,process,function and service,etc.,the position of a certain area in ecological space,structure,process,function and service,etc.is determined through the analysis and research.Regional ecological positioning is an important prerequisite and core basis for regional ecological impact assessment.However,in the current regional ecological impact assessment,most of them have not analyzed and studied the regional ecological positioning.Due to the lack of research on regional ecological positioning,it is rare to apply the research results of regional ecological positioning to the establishment of regional ecological objectives and the construction of index system.Regional ecological positioning does not guide the direction of regional ecological protection and construction well,and there is a general tendency of regional ecological positioning being one-sided and slogan-based.This paper analyzes the necessity and importance of research of regional ecological positioning,puts forward the technology framework of study on regional ecological positioning.With regional ecological positioning research in planning ecological impact assessment of the Chengdu-Chongqing Economic Zone as an example,how to carry out the study on the regional ecological positioning and how to apply the results of the study on the regional ecological positioning in regional ecological impact assessment are explained and illustrated. | Jianqiao QIN Donghang JIANG Fuxing GU Meng HU Rongjin YANG Yingli JIE Zeming ZHENG Haojia XU Xiaoxiao LIAO | 2022 | Meteorological and Environmental Research2022，13，5： | 0 |
| 18 | Improved Hydrogen Storage Kinetics of Nanocrystalline and Amorphous Mg-Nd-Ni-Cubased Mg_2Ni-type Alloys by Adding Nd显示文摘In order to improve the gaseous and electrochemical hydrogen storage kinetics of the M_2Nitype alloy, the elements Cu and Nd were added in the alloy. The nanocrystalline and amorphous Mg_2Ni-type alloys with the composition of(Mg_(24)Ni_(10)Cu(2)_(100-x)Nd_x(x = 0, 5, 10, 15, 20) were prepared by melt spinning technology. The effects of Nd content on the structures and hydrogen storage kinetics of the alloys were investigated. The characterization by X-ray diffraction(XRD), transmission electron microscopy(TEM) and scanning electron microscopy(SEM) reveals that all the as-cast alloys hold multiphase structures, containing Mg_2Ni-type major phase as well as some secondary phases Mg_6Ni, Nd_5Mg_(41), and Nd Ni, whose amounts clearly grow with increasing Nd content. Furthermore, the as-spun Nd-free alloy displays an entire nanocrystalline structure, whereas the as-spun Nd-added alloys hold a mixed structure of nanocrystalline and amorphous structure and the amorphization degree of the alloys visibly increases with the rising of the Nd content, suggesting that the addition of Nd facilitates the glass forming in the Mg_2Ni-type alloy. The measurement of the hydrogen storage kinetics indicates that the addition of Nd significantly improves the gaseous and electrochemical hydrogen storage kinetics of the alloys. The addition of Nd enhances the diffusion ability of hydrogen atoms in the alloy, but it impairs the charge-transfer reaction on the surface of the alloy electrode, which makes the high rate discharge ability(HRD) of the alloy electrode fi rst mount up and then go down with the growing of Nd content. | 张羊换 ZHAI Tingting YANG Tai YUAN Zeming ZHANG Guofang DONG Xiaoping | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，6： | 0 |

| 20 | DNA repair-and nucleotide metabolism-related genes exhibit differential CHG methylation patterns in natural and synthetic polyploids (Brassica napus L.)显示文摘Polyploidization plays a crucial role in the evolution of angiosperm species.Almost all newly formed polyploids encounter genetic or epigenetic instabilities.However,the molecular mechanisms contributing to genomic instability in synthetic polyploids have not been clearly elucidated.Here,we performed a comprehensive transcriptomic and methylomic analysis of natural and synthetic polyploid rapeseeds(Brassica napus).Our results showed that the CHG methylation levels of synthetic rapeseed in different genomic contexts(genes,transposon regions,and repeat regions)were signi fi cantly lower than those of natural rapeseed.The total number and length of CHG-DMRs between natural and synthetic polyploids were much greater than those of CG-DMRs and CHH-DMRs,and the genes overlapping with these CHG-DMRs were signi fi cantly enriched in DNA damage repair and nucleotide metabolism pathways.These results indicated that CHG methylation may be more sensitive than CG and CHH methylation in regulating the stability of the polyploid genome of B.napus.In addition,many genes involved in DNA damage repair,nucleotide metabolism,and cell cycle control were significantly differentially expressed between natural and synthetic rapeseeds.Our results highlight that the genes related to DNA repair and nucleotide metabolism display differential CHG methylation patterns between natural and synthetic polyploids and reveal the potential connection between the genomic instability of polyploid plants with DNA methylation defects and dysregulation of the DNA repair system.In addition,it was found that the maintenance of CHG methylation in B.napus might be partially regulated by MET1.Our study provides novel insights into the establishment and evolution of polyploid plants and offers a potentialidea for improving the genomic stability of newly formed Brassica polyploids. | Liqin Yin Zhendong Zhu Liangjun Huang Xuan Luo Yun Li Chaowen Xiao Jin Yang Jisheng Wang Qiong Zou Lanrong Tao Zeming Kang Rong Tang Maolin Wang Shaohong Fu | 2021 | Horticulture Research2021，8，1： | 0 |
