1Strongly peraluminous granites of Mesozoic in Eastern Nanling Range, southern China: Petrogenesis and implications for tectonics显示文摘The strongly peraluminous granites (SPGs) of Eastern Nanling Range (ENR) are a characteristic of all bearing highly aluminous minerals, such as muscovite±Al-rich biotite±tourmaline±garnet, and lack of cordierite. In respect of petrography, geochemistry, Nd isotope, and single grain zircon U-Pb dating, the representative granite bodies of them are studied. The research shows that these granites were emplaced in two stages, namely 228-225 Ma BP and J2-3 159-156 Ma BP, belonging to Indosinian and early Yanshanian periods, respectively, and they have low εNd(t) values (-10.6--11.1), high A/CNK, Rb/Sr ratios and tDM values (1887-1817 Ma), and REE's tetrad effect (TE1, 3=1.13-1.34). In comparison with related geology, petrology and chronology of granites in adjacent regions, it is suggested that Indosinian SPGs of ENR formed in the circumstance of post-collisional extension 20 Ma after the major collision of Indosinian Movement (258-243 Ma BP) in Indo-China Peninsula, and early Yanshanian SPGs formed in the background of back-arc extension setting controlled by paleo-Pacific tectonic domain, and J1, the interval of two stages, is the interim from Tethyan to Pacific tectonic domains in South China. These SPGs have similar geological and geochemical characteristics, because they all crystallized from the magma of partial melting of early Proterozoic metasedimentary rocks when the thickened crust (≤50 km) became thinning, decompression, and transmitting of water.SUN Tao, ZHOU Xinmin, CHEN Peirong, LI Huimin, ZHOU Hongying, WANG Zhicheng & SHEN Weizhou Department of Earth Sciences, Nanjing University, Nanjing 210093, China Tianjin Institute of Geology and Mineral Resources, China Geological Survey, Tianjin 300170, China 2005Science China Earth Sciences2005,48,2:78

3Tert-butylhydroquinone-decorated graphene nanosheets and their enhanced capacitive behaviors显示文摘In the present work,tert-butylhydroquinone(TBHQ) was used to decorate graphene nanosheets to obtain a novel and environmentally friendly electrode material for supercapacitors.The fast redox reactions between hydroquinone and quinone generate pseudocapacitance.Graphene layers which have adsorbed TBHQ interact with each other to construct a three-dimensional network.Through this network,electrolyte ions can easily access the surface of graphene to generate electric double-layer capacitance.Electrochemical measurements have shown that using TBHQ as a redox modifier of graphene can obtain a maximum value of 302 F g-1 and provide a 51% enhancement in specific capacitance.Furthermore,excellent rate capability and cycling ability are achieved using the TBHQ-decorated graphene nanosheet electrode.WANG HuanWen WU HongYing CHANG YanQin CHEN YanLi HU ZhongAi 2011Chinese Science Bulletin2011,56,20:9
4Inheritance of Perpetual Blooming in Rosa chinensis ‘Old Blush'显示文摘Perpetual blooming is one of the most important biological and economical traits in modern rose, while the genetic basis underlining the control of this trait is poorly investigated. With an aim in dissecting the genetic determinism of perpetual blooming, we developed six rose populations(OB, W, F1, F2, BC1 OB and BC1W) derived from a WOB population [interspecific diploid hybridization between Rosa chinensis ‘Old Blush'(OB) and R. wichuriana ‘Basye's Thornless'(W)]. Perpetual blooming is absent both in a F1 population with 296 individuals and a BC1 W population(W as the backcross parent) with 150 individuals. However, the perpetual blooming trait showed a typical 3︰1 segregation in a backcross population BC1 OB with OB as the backcross parent. In this population with 300 individuals, 83 plants had the perpetual blooming phenotype while the other 217 featured non-perpetual blooming, indicating that the perpetual blooming trait is very likely controlled by two recessive genes in R. chinensis(rpb1 and rpb2). These genetic data suggest that the inheritance of rose perpetual blooming may be controlled by a complex mechanism.LI Shubin ZHOU Ningning ZHOU Qing YAN Huijun JIAN Hongying WANG Qigang CHEN Min QIU Xianqin ZHANG Hao WANG Shufang LI Shufa TANG Kaixue 2015Horticultural Plant Journal2015,1,2:9
5Characteristic Temperatures of Waxy Crude Oils显示文摘Gel point or pour point is widely used to evaluate the low temperature flowability of crude oil. However, it is not adequate to describe the gelling properties of waxy crude oils under flow conditions with gel point or pour point, since the rheological behavior of crude oils is dependent on shear history. Waxy crude oils tend to gel at a low temperature. Based on gelation theory, the characteristic temperature of waxy crude oil was determined by analyzing viscosity-temperature data. Two mathematical models were developed for calculating characteristic temperatures of virgin crude oils and pour point depressants (PPD) beneficiated crude oils, respectively. By using these two models, the characteristic temperatures of crude oils that have experienced shearing and thermal histories can be predicted. The model for predicting the characteristic temperature of virgin crude oils has an average relative deviation of 4.5%, and all predicted values have a deviation within 2 ℃. Tested by 42 sets of data, the prediction model for crude oil treated with PPD has a high accuracy, with an average relative deviation of 4.2%, and 95.2 percent of predicted values have a deviation within 2 ℃. These two models provide useful ways for predicting the flowability of crude oils in pipelines when only wax content, wax appearance point and gel point are available.Zhu Yingru Zhang Jinjun Li Hongying Chen Jun 2007Petroleum Science2007,4,3:6
6Amphiphilic dextran/magnetite nanocomposites as magnetic resonance imaging probes显示文摘Superparamagnetic iron oxide (SPIO) nanoparticles are effective contrast agents for enhancement of magnetic resonance imaging at the tissue, cellular or even molecular levels. High quality SPIO nanoparticles can be synthesized in the organic phase but need to be transferred into water before any biomedical applications. In this study, amphiphilic poly(ε-caprolactone) grafted dextran (Dex-g-PCL) was used as carriers for particle encapsulation and stabilization in the aqueous phase. Multiple SPIO nanoparticles were self-assembled together with the help of Dex-g-PCL during phase transfer from chloroform to water, and diameters of Dex-g-PCL/SPIO nanocomposites were (64 ± 22) nm through dynamic light scattering measurement. These nanocomposites were superparamagnetic at 300 K with saturated magnetization of 88 emu/g Fe. In the magnetic field of 1.5 T, Dex-g-PCL/SPIO nanocomposites had a T2 relaxivity of 363 Fe mL·mol-1·s-1. This unique nanocomposite brought significant mouse liver contrast with signal intensity changes of -60% at 5 min after intravenous administration. However, uptake of Dex-g-PCL/SPIO nanocomposites in liver reticuloendothelial cells (Kupffer cells) did not immediately happen at shorter time points (<4 h) as verified by histology studies, and it was evident that more iron staining would be located in Kupffer cells 24 h after contrast agent administration. After 24 h and 10 d, the signal intensities (SI) gradually recovered, and SI changes were -44% and -31%, respectively. From our observation, the time window for enhanced-MRI could last at least 12 days and totally recovered after 16 days. This novel sensitive MRI contrast agent may find potential applications in discovering small liver lesions such as early tumor diagnosis.WANG QiaoYing SU HongYing XIA ChunChao SUN JiaYu LIU Chen WANG ZhiYong GONG QiYong SONG Bin GAO FaBao AI Hua GU ZhongWei 2009Chinese Science Bulletin2009,54,17:5
7Rational development of a human antibody cocktail that deploys multiple functions to confer Pan-SARS-CoVs protection显示文摘Structural principles underlying the composition and synergistic mechanisms of protective monoclonal antibody cocktails are poorly defined.Here,we exploited antibody cooperativity to develop a therapeutic antibody cocktail against SARS-CoV-2.On the basis of our previously identified humanized cross-neutralizing antibody H014,we systematically an a lyzed a fully human n aive antibody library and rationally identified a potent neutralizing antibody partner,P17,which confers effective protection in animal model.Cryo-EM studies dissected the nature of the P17 epitope,which is SARS-CoV-2 specific and distinctly different from that of HOI4.High-resolution structure of the SARS-CoV-2 spike in complex with HOM and P17,together with functional investigations revealed that in a two-antibody cocktail,synergistic neutralization was achieved by S1 shielding and conformational locking,thereby blocking receptor attachment and viral membrane fusion,conferring high potency as well as robustness against viral mutation escape.Furthermore,cluster analysis identified a hypothetical 3rd antibody partner for further reinforcing the cocktail as pan-SARS-CoVs therapeutics.Hangping Yao Yao Sun Yong-Qiang Deng Nan Wang Yongcong Tan Na-Na Zhang Xiao-Feng Li Chao Kong Yan-Peng Xuc Qi Chen Tian-Shu Cao Hui Zhao Xintian Yan Lei Cao Zhe Lv Dandan Zhu Rui Feng Nanping Wu Wenhai Zhang Yuhao Hu Keda Chen Rong-Rong Zhang Qingyu Lv Shihui Sun Yunhua Zhou Run Yan Guan Yang Xinglu Chanjuan Liu Xiangyun Lu Linfang Cheng Hongying Qiu Xing-Yao Huang Tianhao Weng Danrong Shi Weidong Jiang Junbin Shao Lei Wang Jie Zhang Tao Jiang Guojun Lang Cheng-Feng Qinc Lanjuan Li Xiangxi Wang 2021Cell Research2021,31,1:5
8Characteristics of Heavy Minerals and Quantitative Provenance Identification of Sediments from the Muddy Area Outside the Oujiang Estuary Since 5.8 kyr显示文摘The heavy mineral compositions of the sediments in core D04 with a length of 20.2 m from the muddy area outside the Oujiang Estuary along the coast of Zhejiang-Fujian Provinces have been analyzed. Core D04 can be divided into three units: DU1(0–7.4 m), DU2(7.4–11.4 m) and DU3(11.4–20.2 m). The results showed that the heavy minerals are authigenic pyrite(65.6%)– hornblende(16.0%) – epidote(4.6%) assemblages. The core sediments are mainly composed of clayey silt, which belongs to the clinoform deposit formed since 5.8 kyr, indicating a weak hydrodynamic environment. The deposition rates changed in the trend of high-low-high upward. Quantitative analysis shows that the core sediments were mainly from the suspended sediments of the Changjiang(Yangtze) River, accounting for 79.2%, with only 10.0% from Oujiang, and 10.8% from other provenance. The Oujiang-derived sediments were gradually increased from the bottom unit DU3(3.1%) to the top unit DU1(17.8%), but the Changjiang-derived sediments were gradually decreased. The source changes are closely related to the development of Yangtze River Delta and Wenzhou Bay, climate changes and human activities. During the period of 2.1–3.7 kyr, the sediment supply was greatly reduced due to the poor reclamation capacity of the river basins, resulting in a low deposition rate. Since 2 kyr, the enhancement of human activities in the Yangtze River Basin and the Oujiang River Basin led to more soils to be eroded and transported to the study area. Due to the short distance of the site of core D04 from the Oujiang River mouth, the study area received more Oujiang-derived sediments when upper unit(DU1) deposited than the lower units(DU2 and DU3).SONG Hongying LIU Jinqing YIN Ping ZHANG Yong CHEN Xiaoying 2018Journal of Ocean University of China2018,17,6:4
9Risk assessment of Giardia from a full scale MBR sewage treatment plant caused by membrane integrity failure显示文摘Membrane bioreactors(MBR) are highly efficient at intercepting particles and microbes and have become an important technology for wastewater reclamation. However, many pathogens can accumulate in activated sludge due to the long residence time usually adopted in MBR, and thus may pose health risks when membrane integrity problems occur.This study presents data from a survey on the occurrence of water-borne Giardia pathogens in reclaimed water from a full-scale wastewater treatment plant with MBR experiencing membrane integrity failure, and assessed the associated risk for green space irrigation. Due to membrane integrity failure, the MBR effluent turbidity varied between 0.23 and 1.90 NTU over a period of eight months. Though this turbidity level still met reclaimed water quality standards(≤ 5 NTU), Giardia were detected at concentrations of 0.3 to 95 cysts/10 L, with a close correlation between effluent turbidity and Giardia concentration. All β-giardin gene sequences of Giardia in the WWTP influents were genotyped as Assemblages A and B, both of which are known to infect humans. An exponential dose–response model was applied to assess the risk of infection by Giardia. The risk in the MBR effluent with chlorination was9.83 × 10-3, higher than the acceptable annual risk of 1.0 × 10-4. This study suggested that membrane integrity is very important for keeping a low pathogen level, and multiple barriers are needed to ensure the biological safety of MBR effluent.Yu Zhang Zhimin Chen Wei An Shumin Xiao Hongying Yuan Dongqing Zhang Min Yang 2015Journal of Environmental Sciences2015,27,4:4
10Hippocampal overexpression of TREM2 ameliorates high fat diet induced cognitive impairment and modulates phenotypic polarization of the microglia显示文摘Type 2 diabetes mellitus(T2DM)and Alzheimer's disease(AD)share several common pathophysiological features.Rare variants of triggering receptor expressed on myeloid cells 2(TREM2)increase the risk of developing AD,suggesting the involvement of TREM2 and innate immunity in AD development.It is still unknown whether TREM2 is related to cognitive impairment in T2DM.Here,we investigated the effects of the hippocampal overexpression of TREM2 on cognitive in long-term high-fat diet(HFD)-fed mice.Male C57BL/6J mice were maintained on HFD for 50 weeks.TREM2 was overexpressed in the hippocampus 36 weeks after HFD feeding using adeno-associated virus vector(AAV)-mediated gene delivery.The results showed that the HFD feeding induced rapid and persistent weight gain,glucose intolerance and significant impairments in learning and memory.Compared with AAV-con,AAV-TREM2 significantly ameliorated cognitive impairment without altering body weight and glucose homeostasis in HFD mice.The overexpression of TREM2 upregulated the synaptic proteins spinophilin,PSD95 and synaptophysin,suggesting the improvement in synaptic transmission.Dendritic complexity and spine density in the CA1 region were rescued after TREM2 overexpression.Furthermore,TREM2 markedly increased the number of iba-1/Arg-1-positive microglia in the hippocampus,suppressed neuroinflammation and microglial activation.In sum,hippocampal TREM2 plays an important role in improving HFD-induced cognitive dysfunction and promoting microglial polarization towards the M2 anti-inflammatory phenotype.Our study also suggests that TREM2 might be a novel target for the intervention of obesity/diabetes-associated cognitive decline.Min Wu Maolin Liao Rongfeng Huang Chunxiu Chen Tian Tian Hongying Wang Jiayu Li Jibin Li Yuxiang Sun Chaodong Wu Qifu Li Xiaoqiu Xiao 2022Genes & Diseases2022,9,2:4

12Soliton and bound-state soliton mode-locked fiber laser based on a MoS_2/fluorine mica Langmuir–Blodgett film saturable absorber显示文摘In this article, we report on an experimentally generated soliton and bound-state soliton passively mode-locked erbium-doped fiber laser by incorporating a saturable absorber(SA) made of MoS2∕fluorine mica(FM) that was fabricated with the Langmuir–Blodgett(LB) method. The FM substrate is 20 μm thick and easy to bend or cut,like a polymer. However, it has a higher damage threshold and a better thermal dissipation than polymers.In addition, the LB method can be used to fabricate a thin film with good uniformity. In this study, the modulation depth, saturable intensity, and unsaturated loss of the SA are measured as 5.9%, 57.69 MW∕cm2, and13.4%, respectively. Based on the SA, a soliton mode-locked laser is achieved. The pulse duration, repetition rate, and signal-to-noise ratio are 581 fs, 15.67 MHz, and 65 dB, respectively. By adjusting the polarization controller and pump power, we obtain a bound-state soliton mode-locked pulse. The temporal interval between the two solitons forming the bound-state pulse is 2.7 ps. The repetition rate of the bound-state pulses is proportional to the pump power. The maximum repetition rate is 517 MHz, corresponding to the 33 rd harmonic of the fundamental repetition rate. The results indicate that the MoS2∕FM LB film absorber is a promising photonic device in ultrafast fiber lasers.RUIDONG Lü YONGGANG WANG JIANG WANG WEI REN LU LI SICONG LIU ZHENDONG CHEN YONGFANG LI HONGYING WANG FUXING FU 2019Photonics Research2019,7,4:2
13Carboniferous ridge subduction in the Xingmeng Orogenic Belt:Constraints from geochronological,geochemical,and Sr-Nd-Hf isotopic analysis of strongly peraluminous granites and gabbro-diorites in the Xilinhot micro-continent显示文摘The Xingmeng Orogenic Belt evolved through a long-lived orogeny involving multiple episodes of subduction and accretion.However,there is a debate on its tectonic evolution during the Late Paleozoic.Here,we report geochemical,geochronological,and isotopic data from strongly peraluminous granites and gabbro-diorites from the Sunidzuoqi-Xilinhot region.Zircon U-Pb ages suggest that the intrusive rocks were emplaced during the Early Carboniferous(333-322 Ma).The granites exhibit geochemical characteristics similar to S-type granites,with high SiO_(2)(72.34-76.53 wt.%),Al_(2)O_(3)(12.45-14.65 wt.%),and A/CNK(1.07-1.16),but depleted Sr,Nb,and Ta contents.They exhibit positiveε_(Nd)(t)andε_(Hf)(t)values(-0.3 to 2.8 and 2.7-5.7,respectively)and young Nd and Hf model ages(T_(DM2)(Nd)=853-1110 Ma and T_(DM2)(Hf)=975-1184 Ma),suggesting that they may be the partial melting products of heterogeneous sources with variable proportions of pelite,psammite,and metabasaltic rocks.The meta-gabbro-diorites from the Maihantaolegai pluton have low SiO_(2)(47.06-53.49 wt.%)and K_2O(0.04-0.99 wt.%)contents,and demonstrate slight light rare earth element(REE)depletion in the chondritenormalized REE diagrams.They have high zirconε_(Hf)(t)values(14.41-17.34)and young Hf model ages(T_(DM2)(Hf)=230-418 Ma),indicating a more depleted mantle source.The variations of the Sm/Yb and La/Sm ratios can thus be used to assess the melting degree of the mantle source from 5%to 20%,suggesting a quite shallow mantle melting zone.We propose that the petrogenesis and distribution of the strongly peraluminous granites and gabbro-diorites,as well as the tectonic architecture of the region,can be explained by a ridge subduction model.Based on these results,and previous studies,we suggest a southward ridge subduction model for the Sunidzuoqi-Xilinhot region.Changfeng Liu Zhiguang Zhou Guosheng Wang Chen Wu Hongying Li Shiwei Ma 2021Geoscience Frontiers2021,12,3:2
14Embryo implantation:A time for recalling and forwarding显示文摘The success of embryo implantation is a critical step towards further embryo development and pregnancy outcome. The observations and investigations on embryo implantation have been over a century. A huge body of knowledge has been accumulated in anatomy, histology, ultrastructure and hormonal regulation; as well as recently in depth information about molecular signaling pathways got from studies of genomic wide gene screening and specific gene deletion. The knowledge from basic research has also substantially helped to initiate and improve the Artificial Reproductive Technology (ART) in clinical applications. Now we've known that the normal embryo implantation involves the embryo's development into an implantation-competent blastocyst and the synchronized transformation of uteri into a receptive stage. The interdependent relationship between the blastocyst and uterus involves complicated hormonal regulation and local paracrine, juxtacrine interactions. In this paper, we review some important historical findings regarding uterine receptivity and blastocyst activation, as well as some less discussed topics such as embryo spacing, embryo orientation. Further understandings on detailed mechanisms during the process of embryo implantation will help cure women infertility as well as develop new generation of non-steroids contraceptives.CHEN Qi PENG HongYing ZHANG Ying LEI Li CAO YuJing Duan EnKui 2009Chinese Science Bulletin2009,54,22:2
15Human-animal interactions and bat coronavirus spillover potential among rural residents in Southern China显示文摘Human interaction with animals has been implicated as a primary risk factor for several high impact zoonoses,including many bat-origin viral diseases.However the animal-to-human spillover events that lead to emerging diseases are rarely observed or clinically examined,and the link between specific interactions and spillover risk is poorly understood.To investigate this phenomenon,we conducted biological-behavioral surveillance among rural residents in Yunnan,Guangxi,and Guangdong districts of Southern China,where we have identified a number of SARS-related coronaviruses in bats.Serum samples were tested for four bat-borne coronaviruses using newly developed enzyme-linked immunosorbent assays(ELISA).Survey data were used to characterize associations between human-animal contact and bat coronavirus spillover risk.A total of 1,596 residents were enrolled in the study from 2015 to 2017.Nine participants(0.6%)tested positive for bat coronaviruses.265(17%)participants reported severe acute respiratory infections(SARI)and/or influenza-like illness(ILI)symptoms in the past year,which were associated with poultry,carnivore,rodent/shrew,or bat contact,with variability by family income and district of residence.This study provides serological evidence of bat coronavirus spillover in rural communities in Southern China.The low seroprevalence observed in this study suggests that bat coronavirus spillover is a rare event.Nonetheless,this study highlights associations between human-animal interaction and zoonotic spillover risk.These findings can be used to support targeted biological behavioral surveillance in high-risk geographic areas in order to reduce the risk of zoonotic disease emergence.Li Hongying Mendelsohn Emma Zong Chen Zhang Wei Hagan Emily Wang Ning Li Shiyue Yan Hong Huang Huimin Zhu Guangjian Ross Noam Chmura Aleksei Terry Philip Fielder Mark Miller Maureen Shi Zhengli Daszak Peter 2019Biosafety and Health2019,1,2:2
