1Fermented soybean meal improves the growth performance, nutrient digestibility, and microbial flora in piglets显示文摘In order to increase nutritive values of soybean meal(SBM), 3 species of microbes were used to ferment SBM. Through a 3 x 3 orthogonal design and parameter measurements of soybean peptide and antinutritional factor contents in the fermented soybean meal(FSBM), it was estimated that the best microbial proportion of Bacillus subtilis, Hansenula anomala and Lactobacillus casei was 2:1:2 for SBM fermentation(P < 0.05). The further piglet feeding experiment showed that 10% FSBM substitute for SBM had no significant effect on growth performance of suckling piglets(d 7-28)(P> 0.05). However, newlyweaned piglets(d 28-38) fed 10% FSBM and different levels of plasma protein obtained higher average daily gain(ADG) and feed conversion ratio(FCR), compared with those without FSBM but with 6% plasma protein(P < 0.05). Piglets(d 38-68) fed diets supplemented with FSBM and soybean protein concentrate(SBPC) at 3.75% and 7.5% respectively increased nutrient digestibility,fecal enzyme activity and lactic acid bacteria counts, and decreased fecal Escherichia coli counts(P < 0.05), compared with the control. These data indicated that FSBM had positive effects on nutrient digestibility and fecal microflora for piglets.Lin Yuan Juan Chang Qingqiang Yin Min Lu Yuanran Di Ping Wang Zhixiang Wang Erzhu Wang Fushan Lu 2017Animal Nutrition2017,,1:31

3Infection with novel coronavirus(SARS-CoV-2)causes pneumonia in Rhesus macaques显示文摘The 2019 novel coronavirus(SARS-CoV-2)outbreak is a major challenge for public health.SARS-CoV-2 infection in human has a broad clinical spectrum ranging from mild to severe cases,with a mortality rate of^6.4%worldwide(based on World Health Organization daily situation report).However,the dynamics of viral infection,replication and shedding are poorly understood.Here,we show that Rhesus macaques are susceptible to the infection by SARS-CoV-2.After intratracheal inoculation,the first peak of viral RNA was observed in oropharyngeal swabs one day post infection(1 d.p.i.),mainly from the input of the inoculation,while the second peak occurred at 5 d.p.i.,which reflected on-site replication in the respiratory tract.Histopathological observation shows that SARS-CoV-2 infection can cause interstitial pneumonia in animals,characterized by hyperemia and edema,and infiltration of monocytes and lymphocytes in alveoli.We also identified SARS-CoV-2 RNA in respiratory tract tissues,including trachea,bronchus and lung;and viruses were also re-isolated from oropharyngeal swabs,bronchus and lung,respectively.Furthermore,we demonstrated that neutralizing antibodies generated from the primary infection could protect the Rhesus macaques from a second-round challenge by SARS-CoV-2.The non-human primate model that we established here provides a valuable platform to study SARS-CoV-2 pathogenesis and to evaluate candidate vaccines and therapeutics.Chao Shan Yan-Feng Yao Xing-Lou Yang Yi-Wu Zhou Ge Gao Yun Peng Lian Yang Xue Hu Jin Xiong Ren-Di Jiang Hua-Jun Zhang Xiao-Xiao Gao Cheng Peng Juan Min Ying Chen Hao-Rui Si Jia Wu Peng Zhou Yan-Yi Wang Hong-Ping Wei Wei Pang Zheng-Fei Hu Long-Bao Lv Yong-Tang Zheng Zheng-Li Shi Zhi-Ming Yuan 2020Cell Research2020,30,8:19
4Liver Enzymes Concentrations Are Closely Related to Pre-diabetes:Findings of the Shanghai Diabetes Study Ⅱ (SHDS Ⅱ)显示文摘Objective To investigate the relationship of liver enzymes with hyperglycemia in a large population in Shanghai and identify the association between liver enzymes and insulin resistance.Methods A total of 3 756 participants were enrolled.Each participant underwent an oral glucose tolerance test and completed a questionnaire.Anthropometric indices were recorded and serum samples were collected for measurement.Results Liver enzymes concentrations were independently associated with i-IGT,IFG+IGT,and diabetes.With the increase of ALT and GGT concentrations,ORs for i-IGT,IFG+IGT,and diabetes increased gradually.By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile (Q1),ORs for i-IGT,IFG+IGT,or diabetes was significant after adjustment.Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR (95% CI):2.56 (1.51-4.34) P=0.00;GGT OR (95% CI):2.66 (1.53-4.65) P=0.00].Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance.GAO Fei PAN Jie Min HOU Xu Hong FANG Qi Chen LU Hui Juan TANG Jun Ling GU Hui Lin PAN Zhi Jian YAO You Hua SHEN Wei Zhen JIA Wei Ping 2012Biomedical and Environmental Sciences2012,25,1:15
5Antioxidant and Anti-inflammatory Capacity of Ferulic Acid Released from Wheat Bran by Solid-state Fermentation of Aspergillus niger显示文摘Objective A strain of Aspergillus niger(A. niger), capable of releasing bound phenolic acids from wheat bran, was isolated. This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain(FA-WB) were evaluated. Methods Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity(ORAC), cellular antioxidant activity(CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity. Results The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species(ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-?, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide(LPS). Conclusion Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid.YIN Zhi Na WU Wen Jia SUN Chong Zhen LIU Hui Fan CHEN Wen Bo ZHAN Qi Ping LEI Zhuo Gui XIN Xuan MA Juan Juan YAO Kun MIN Tian ZHANG Meng Meng WU Hui 2019Biomedical and Environmental Sciences2019,32,1:14
6Characterization of disinfection byproduct formation potential in 13 source waters in China显示文摘The formation potential of four trihalomethanes (THMFP) and seven haloacetic acids (HAA 7 FP) in 13 source waters taken from four major water basin areas in China was evaluated using the simulated distribution system (SDS) chlorination method.The specific ultraviolet absorbance (SUVA 254:the ratio of UV 254 to dissolved organic carbon (DOC)),which ranged between 0.9 and 5.0 L/(mg·m),showed that the organic compounds in different source waters exhibited different reactivities with chlorine.The HAA 7 FP of source waters ranged from 20 to 448 μg/L and the THMFP ranged from 29 to 259 μg/L.The HAA 7 FP concentrations were higher than the THMFP concentrations in all but one of the samples.Therefore,the risks of haloacetic acids (HAAs) should be of concern in some source waters.TCM (chloroform) and BDCM (bromodichloromethane) were the major THM constituents,while TCAA (trichloroacetic acid) and DCAA (dichloroacetic acid) were the major HAA species.Br-THM (brominated THM species) were much higher than BrHAA (brominated HAA species),and the formation of Br-DBP (Br-THM and Br-HAA) should be of concern when the bromide concentration is over 100 μg/L.Junzhi Zhang Jianwei Yu Wei An Juan Liu Yongjing Wang Youjun Chen Jia Tai Min Yang 2011Journal of Environmental Sciences2011,23,2:13
7Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
8Bioactive biodegradable polycitrate nanoclusters enhances the myoblast differentiation and in vivo skeletal muscle regeneration via p38 MAPK signaling pathway显示文摘Complete skeletal muscle repair and regeneration due to severe large injury or disease is still a challenge.Biochemical cues are critical to control myoblast cell function and can be utilized to develop smart biomaterials for skeletal muscle engineering.Citric acid-based biodegradable polymers have received much attention on tissue engineering,however,their regulation on myoblast cell differentiation and mechanism was few investigated.Here,we find that citrate-based polycitrate-polyethylene glycol-polyethylenimine(POCG-PEI600)nanoclusters can significantly enhance the in vitro myoblast proliferation by probably reinforcing the mitochondrial number,promote the myotube formation and full-thickness skeletal muscle regeneration in vivo by activating the myogenic biomarker genes expression of Myod and Mhc.POCG-PEI600 nanoclusters could also promote the phosphorylation of p38 in MAP kinases(MAPK)signaling pathway,which led to the promotion of the myoblast differentiation.The in vivo skeletal muscle loss rat model also confirmed that POCG-PEI600 nanoclusters could significantly improve the angiogenesis,myofibers formation and complete skeletal muscle regeneration.POCG-PEI600 nanocluster could be also biodegraded into small molecules and eliminated in vivo,suggesting their high biocompatibility and biosafety.This study could provide a bioactive biomaterial-based strategy to repair and regenerate skeletal muscle tissue.Yi Guo Min Wang Juan Ge Wen Niu Mi Chen Wei Cheng Bo Lei 2020Bioactive Materials2020,5,3:12

10The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
11Protective Effect of Resveratrol on the Brain in a Rat Model of Epilepsy显示文摘Accumulating evidence has suggested resveratrol as a promising drug candidate for the treatment of epilepsy. To validate this, we tested the protective effect of resveratrol on a kainic acid(KA)-induced epilepsy model in rats and investigated the underlying mechanism. We found that acute resveratrol application partially inhibited evoked epileptiform discharges in the hippocampal CA1 region. During acute, silent and chronic phases of epilepsy,the expression of hippocampal kainate glutamate receptor(GluK2) and the GABAAreceptor alpha1 subunit(GABAAR-alpha1) was up-regulated and down-regulated,respectively. Resveratrol reversed these effects and induced an antiepileptic effect. Furthermore, in the chronic phase, resveratrol treatment inhibited the KA-induced increased glutamate/GABA ratio in the hippocampus. The antiepileptic effects of resveratrol may be partially attributed to the reduction of glutamate-induced excitotoxicity and the enhancement in GABAergic inhibition.Zhen Li Zhuyan You Min Li Liang Pang Juan Cheng Liecheng Wang 2017Neuroscience Bulletin2017,33,3:11
12Major Modes of Short-Term Climate Variability in the Newly Developed NUIST Earth System Model(NESM)显示文摘A coupled earth system model(ESM) has been developed at the Nanjing University of Information Science and Technology(NUIST) by using version 5.3 of the European Centre Hamburg Model(ECHAM), version 3.4 of the Nucleus for European Modelling of the Ocean(NEMO), and version 4.1 of the Los Alamos sea ice model(CICE). The model is referred to as NUIST ESM1(NESM1). Comprehensive and quantitative metrics are used to assess the model's major modes of climate variability most relevant to subseasonal-to-interannual climate prediction. The model's assessment is placed in a multi-model framework. The model yields a realistic annual mean and annual cycle of equatorial SST, and a reasonably realistic precipitation climatology, but has difficulty in capturing the spring–fall asymmetry and monsoon precipitation domains. The ENSO mode is reproduced well with respect to its spatial structure, power spectrum, phase locking to the annual cycle, and spatial structures of the central Pacific(CP)-ENSO and eastern Pacific(EP)-ENSO; however, the equatorial SST variability,biennial component of ENSO, and the amplitude of CP-ENSO are overestimated. The model captures realistic intraseasonal variability patterns, the vertical-zonal structures of the first two leading predictable modes of Madden–Julian Oscillation(MJO), and its eastward propagation; but the simulated MJO speed is significantly slower than observed. Compared with the T42 version, the high resolution version(T159) demonstrates improved simulation with respect to the climatology, interannual variance, monsoon–ENSO lead–lag correlation, spatial structures of the leading mode of the Asian–Australian monsoon rainfall variability, and the eastward propagation of the MJO.CAO Jian Bin WANG Baoqiang XIANG Juan LI WU Tianjie Xiouhua FU WU Liguang MIN Jinzhong 2015Advances in Atmospheric Sciences2015,32,5:10
13Monitoring of 943 organic micropollutants in wastewater from municipal wastewater treatment plants with secondary and advanced treatment processes显示文摘To perform a systematic survey on the occurrence and removal of micropollutants during municipal wastewater treatment, 943 semi-volatile organic chemicals in 32 wastewater samples including influents of secondary treatments, secondary effluents and final effluents(effluents of advanced treatments), which were collected from seven full-scale municipal wastewater treatment plants(MWTPs) in China, were examined by gas chromatography-mass spectrometry(GC-MS) coupled with an automated identification and quantification system with a database(AIQS-DB). In total, 196 and 145 chemicals were detected in secondary and final effluents, respectively. The majority of the total concentrations(average removal efficiency, 87.0%±5.9%) of the micropollutants were removed during secondary treatments. However, advanced treatments achieved different micropollutant removal extents from secondary effluents depending on the different treatment processes employed. Highly variable removal efficiencies of total concentrations(32.7%–99.3%) were observed among the different advanced processes. Among them,ozonation-based processes could remove 70.0%–80.9% of the total concentrations of studied micropollutants. The potentially harmful micropollutants, based on their detection frequency and concentration in secondary and final effluents, were polycyclic aromatic hydrocarbons(PAHs)(2-methylnaphthalene, fluoranthene, pyrene, naphthalene and phenanthrene), phosphorus flame retardants(tributyl phosphate(TBP), tris(2-chloroethyl)phosphate(TCEP) and tris(1,3-dichloro-2-propyl) phosphate(TDCP)), phthalates(bis(2-ethylhexyl)phthalate(DEHP)), benzothiazoles(benzothiazole,2-(methylthio)-benzothiazol, and 2(3H)-benzothiazolone) and phenol. This study indicated that the presence of considerable amounts of micropollutants in secondary effluent creates the need for suitable advanced treatment before their reuse.Juan Wang Zhe Tian Yingbin Huo Min Yang Xingcan Zheng Yu Zhang 2018Journal of Environmental Sciences2018,30,5:9
14Advanced oxidation of bromide-containing drinking water: A balance between bromate and trihalomethane formation control显示文摘Addition of H2O2 has been employed to repress bromate formation during ozonation of bromide-containing source water.However,the addition of H2O2 will change the oxidation pathways of organic compounds due to the generation of abundant hydroxyl radicals,which could afect the removal efcacy of trihalomethane precursors via the combination of ozone and biological activated carbon(O3-BAC).In this study,we evaluated the efects of H2O2 addition on bromate formation and trihalomethane formation potential(THMFP)reduction during treatment of bromide-containing(97.6–129.1μg/L)source water by the O3-BAC process.At an ozone dose of 4.2 mg/L,an H2O2/O3(g/g)ratio of over 1.0 was required to maintain the bromate concentration below 10.0μg/L,while a much lower H2O2/O3ratio was sufcient for a lower ozone dose.An H2O2/O3(g/g)ratio below 0.3 should be avoided since the bromate concentration will increase with increasing H2O2 dose below this ratio.However,the addition of H2O2 at an ozone dose of 3.2 mg/L and an H2O2/O3 ratio of 1.0 resulted in a 43% decrease in THMFP removal when compared with the O3-BAC process.The optimum H2O2/O3(g/g) ratio for balancing bromate and trihalomethane control was about 0.7–1.0.Fractionation of organic materials showed that the addition of H2O2 decreased the removal efcacy of the hydrophilic matter fraction of DOC by ozonation and increased the reactivity of the hydrophobic fractions during formation of trihalomethane,which may be the two main reasons responsible for the decrease in THMFP reduction efcacy.Overall,this study clearly demonstrated that it is necessary to balance bromate reduction and THMFP control when adopting an H2O2 addition strategy.Yongjing Wang Jianwei Yu Po Han Jing Sha Tao Li Wei An Juan Liu Min Yang 2013Journal of Environmental Sciences2013,25,11:9
15Receptome profiling identifies KREMEN1 and ASGR1 as alternative functional receptors of SARS-CoV-2显示文摘Host cellular receptors play key roles in the determination of virus tropism and pathogenesis.However,little is known about SARS-CoV-2 host receptors with the exception of ACE2.Furthermore,ACE2 alone cannot explain the multi-organ tropism of SARS-CoV-2 nor the clinical differences between SARS-CoV-2 and SARS-CoV,suggesting the involvement of other receptor(s).Here,we performed genomic receptor profiling to screen 5054 human membrane proteins individually for interaction with the SARS-CoV-2 capsid spike(S)protein.Twelve proteins,including ACE2,ASGR1,and KREMEN1,were identified with diverse S-binding affinities and patterns.ASGR1 or KREMEN1 is sufficient for the entry of SARS-CoV-2 but not SARS-CoV in vitro and in vivo.SARS-CoV-2 utilizes distinct ACE2/ASGR1/KREMEN1(ASK)receptor combinations to enter different cell types,and the expression of ASK together displays a markedly stronger correlation with virus susceptibility than that of any individual receptor at both the cell and tissue levels.The cocktail of ASK-related neutralizing antibodies provides the most substantial blockage of SARS-CoV-2 infection in human lung organoids when compared to individual antibodies.Our study revealed an interacting host receptome of SARS-CoV-2,and identified ASGR1 and KREMEN1 as alternative functional receptors that play essential roles in ACE2-independent virus entry,providing insight into SARS-CoV-2 tropism and pathogenesis,as well as a community resource and potential therapeutic strategies for further COVID-19 investigations.Yunqing Gu Jun Cao Xinyu Zhang Hai Gao Yuyan Wang Jia Wang Juan He Xiaoyi Jiang Jinlan Zhang Guanghui Shen Jie Yang Xichen Zheng Gaowei Hu Yuanfei Zhu Shujuan Du Yunkai Zhu Rong Zhang Jianqing Xu Fei Lan Di Qu Guoliang Xu Yun Zhao Dong Gao Youhua Xie Min Luo Zhigang Lu 2022Cell Research2022,32,1:8

17Molecular characterization of effluent organic matter in secondary effluent and reclaimed water:Comparison to natural organic matter in source water显示文摘Municipal wastewater reclamation is becoming of increasing importance in the world to solve the problem of water scarcity. A better understanding of the molecular composition of effluent organic matter(Ef OM) in the treated effluents of municipal wastewater treatment plants(WWTPs) is crucial for ensuring the safety of water reuse. In this study, the molecular composition of Ef OM in the secondary effluent of a WWTP in Beijing and the reclaimed water further treated with a coagulation–sedimentation–ozonation process were characterized using a non-target Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS) method and compared to that of natural organic matter(NOM) in the local source water from a reservoir. It was found that the molecular composition of Ef OM in the secondary effluent and reclaimed water was dominated by CHOS formulas, while NOM in the source water was dominated by CHO formulas. The CHO formulas of the three samples had similar origins. Anthropogenic surfactants were responsible for the CHOS formulas in Ef OM of the secondary effluent and were not well removed by the coagulation-sedimentation-ozonation treatment process adopted.Xin Wang Juan Wang Kuixiao Li Haifeng Zhang Min Yang 2018Journal of Environmental Sciences2018,30,1:7
18Effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats显示文摘Objective To study the effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats. Methods Rat tail-suspension model was used to simulate the physiological effects of microgravity and changes in pulmonary blood vessel morphology, pulmonary arterial and venous blood pressure, pulmonary vascular resistance, pulmonary vasomotoricity, as well as the regulation of pulmonary circulation by cytokines produced and released by the lung of rats were measured. Results The walls of pulmonary blood vessels of rats were thickened, and the pulmonary artery was reconstructed with increased pulmonary vascular resistance. The pulmonary blood vessels of rats became more prone to dilation as contractions increased. Rat epithelial Adrenomedulin gene transcription and protein expression were upregulated. The level of basic fibroblast growth Factor of rat was also elevated.

19Evaluation of internal and shell stiffness in the differential diagnosis of breast non-mass lesions by shear wave elastography显示文摘BACKGROUND The diagnostic specificity of conventional ultrasound for breast non-mass lesions(NMLs)is low at approximately 21%-43%.Shear wave elastography(SWE)can distinguish benign from malignant lesions by evaluating the internal and peripheral stiffness.SWE has good reproducibility and high diagnostic efficacy.However,there are very few independent studies on the diagnostic value of SWE in breast NMLs.AIM To determine the value of SWE in the differential diagnosis of breast NMLs.METHODS This study enrolled a total of 118 patients with breast NMLs who underwent SWE examinations in the Beijing Shijitan Hospital Affiliated to Capital Medical University and The Second Hospital of Shandong University from January 2019 to January 2020.The internal elastic parameters of the lesions were recorded,including maximum(Emax),mean(Emean)and minimum elastic values and the standard deviation.The following peripheral parameters were noted:Presence of a“stiff rim”sign;Emax,and Emean elasticity values within 1 mm,1.5 mm,2 mm,2.5 mm and 3 mm from the edge of NMLs.The receiver operating characteristic curve of each parameter was drawn,and the areas under the curve were calculated.RESULTS Emax,Emean and elastic values,and the standard deviation of the internal elastic values in malignant NMLs were significantly higher than those in benign NMLs(P<0.05).The percentage with the“stiff rim”sign in malignant NMLs was significantly higher than that in the benign group(P<0.05),and Emax and Emean at the shell of 1 mm,1.5 mm,2 mm,2.5 mm and 3 mm in the malignant group were all higher than those in the benign group(P<0.05).Of the surrounding elasticity values,Emax of the shell at 2.5 mm in malignant NMLs had maximum areas under the curve of 0.900,and the corresponding sensitivity and specificity were 94.57%and 85.86%,respectively.CONCLUSION The“stiff rim”sign and multiple quantitative elastic values within and around the lesion had good diagnostic performance in the differential diagnosis of breast NMLs.Emax in peripheral tissue had better diagnostic efficiency than other parameters.Ping Xu Mei Wu Min Yang Juan Xiao Zheng-Min Ruan Lan-Ying Wu 2020World Journal of Clinical Cases2020,8,12:6
20Autophagy Attenuates MnCl2-induced Apoptosis in Human Bronchial Epithelial Cells显示文摘Objective To investigate the role of autophagy in MnC l2-induced apoptosis in human bronchial epithelial 16 HBE cells.Methods Cell proliferation was measured by MTT assay.Mitochondrial membrane potential(MMP) and apoptosis were measured by flow cytometry.Autophagic vacuoles were detected by fluorescence microscopy.Cellular levels of apoptosis and autophagy-related proteins were measured by western blotting.Results 16 HBE cell proliferation was inhibited by Mn Cl2 in a dose-and time-dependent manner.Mn Cl2-induced 16 HBE cell growth inhibition was related to MMP depolarization prior to the induction of apoptosis.Our data revealed that Mn Cl2-induced apoptosis in 16 HBE cells was mediated by decreased expression of Bcl-2 and increased levels of cleaved caspase-3.It was observed that when we exposed 16 HBE cells to MnCl_2 in a dose-dependent manner,the formation of autophagic vacuoles and the levels of LC-3B-II were elevated.RNA interference of LC3 B in these Mn Cl2-exposed cells demonstrated that MMP loss and apoptosis were enhanced.Additionally,the pan-caspase inhibitor Z-VAD-FMK increased the cellular levels of Bcl-2 and decreased apoptosis,but did not affect the cellular levels of LC3 B in Mn Cl2-treated 16 HBE cells.Conclusion Mn Cl2 dose-and time-dependently inhibits 16 HBE cell proliferation and induces MMP loss and apoptosis.Autophagy acts in a protective role against Mn Cl2-induced apoptosis in 16 HBE cells.YUAN Zhun YING Xian Ping ZHONG Wei Jian TIAN Shi Min WANG Yu JIA Yong Rui CHEN Wen FU Juan Ling ZHAO Peng ZHOU Zong Can 2016Biomedical and Environmental Sciences2016,29,7:5
