| 5 | Laser-induced Janus graphene/poly(p-phenylene benzobisoxazole)fabrics with intrinsic flame retardancy as flexible sensors and breathable electrodes for fire-fighting field显示文摘Conventional firefighting clothing and fire masks can protect firemen’s safety to a certain extent,whereas cannot perceive environmental hazards and monitor their physical status in real time.Herein,we fabricated two kinds of Janus graphene/poly(pphenylene benzobisoxazole)(PBO)fabrics by laser direct writing approach and evaluated their performance as intelligent firefighting clothes and fire masks.The results showed that the Janus graphene/PBO fabrics were virtually non-combustible and achieved the highest thermal protection time of 18.91 s ever reported in flame,which is due to the intrinsic flame-retardant nature of PBO fibers.The graphene/PBO woven fabrics-based sensor showed good repeatability and stability in human motion monitoring and NO_(2)gas detection.Furthermore,the piezoelectric fire mask was assembled with graphene/PBO nonwoven fabric as electrode layer and polyvinylidene fluoride(PVDF)electrostatic direct writing film as piezoelectric layer.The filtration efficiency of the fire mask reaches 95%for PM_(2.5)and 100%for PM_(3.0),indicating its effective filtration capability for smoke particles in fires.The respiratory resistance of the piezoelectric fire mask(46.8 Pa)was lower than that of commercial masks(49 Pa),showing that it has good wearing comfort.Besides,the piezoelectric fire mask can be sensitive to the speed and intensity of human breathing,which is essential for indirectly reflecting the health of the human body.Consequently,this work provides a facile approach to fabricate next-generation intrinsic flame-retardant smart textiles for smart firefighting. | Yu Luo Yaping Miao Huimin Wang Kai Dong Lin Hou Yanyan Xu Weichun Chen Yao Zhang Yingying Zhang Wei Fan | 2023 | Nano Research2023,16,5: | 2 |
| 6 | Pandemic threat posed by H3N2 avian influenza virus显示文摘Dear Editor,In the last century,H1N1,H2N2,and H3N2 influenza viruses caused pandemics in 1918,1957,and 1968,respectively.In 2009,a novel H1N1 reassortant jumped from pigs to humans and caused a fourth influenza pandemic.Different lineages of H3N2 influenza viruses are commonly found in animal reservoirs.If a different lineage of H3N2 virus jumps to humans,another human influenza pandemic could occur with devastating consequences. | Yaping Zhang Conghui Zhao Yujie Hou Yan Chen Fei Meng Yichao Zhuang Liling Liu Yasuo Suzuki Jianzhong Shi Guohua Deng Hualan Chen | 2021 | Science China(Life Sciences)2021,64,11: | 2 |
| 7 | Expression Profiles of SIRT1 and APP Genes in Human Neuroblastoma SK-N-SH Cells Treated with Two Epigenetic Agents显示文摘In our previous studies, significant hypermethylation of the sirtuin 1(SIRT1) gene and demethylation of the b-amyloid precursor protein(APP) gene were found in patients with Alzheimer's disease(AD) compared with the normal population. Moreover, the expression of SIRT1 was significantly decreased while that of APP was increased in AD patients. These results indicated a correlation of DNA methylation with gene expression levels in AD patients. To further investigate the epigenetic mechanism of gene modulation in AD, we used two epigenetic drugs, the DNA methylation inhibitor 5-aza-20-deoxycytidine(DAC) and the histone deacetylase inhibitor trichostatin A(TSA), to treat human neuroblastoma SK-N-SH cells in the presence of amyloid b-peptide Ab25–35(Ab25–35). We found that DAC and TSA had different effects on the expression trends of SIRT1 and APP in the cell model of amyloid toxicity. Although other genes, such as microtubule-associated protein s, presenilin 1, presenilin 2, and apolipoprotein E, were up-regulated after Ab25–35treatment, no significant differences were found after DAC and/or TSA treatment. These results support the evidence in AD patients and reveal a strong correlation of SIRT1/APP expression with DNA methylation and/or histone modification, which may help understand the pathogenesis of AD. | Yaping Hou Fanghua Wang Linping Cheng Tao Luo Jie Xu Huaqiao Wang | 2016 | Neuroscience Bulletin2016,32,5: | 2 |
| 8 | DNA methylation and alternative splicing modulate FBXW11 gene expression in Holstein bull testis and are correlated with sperm quality显示文摘F-box and WD-40 domain protein 11(FBXW11)is an important component of the E3 ubiquitin-ligase enzyme that plays a key role in the ubiquitin-dependent regulation of spermatogenesis.In our previous research,the mRNA expression of FBXW11 in bull sperm with high motility is significantly higher than that with low motility.In the present study,the protein expression levels of FBXW11 in bull testicular tissues with low-performance sperm quality groups were significantly higher than those in normal performance groups.The immunohistochemistry result demonstrated that FBXW11 protein was located in the periphery of Leydig cells and seminiferous tubules.Three splice variants of the FBXW11 gene,namely,FBXW11-tv1,FBXW11-tv2,and FBXW11-tv3,were identified in testicular tissues.The splicing patterns of the three variants are exon skipping.The transcript FBXW11-tv2 expressions were the highest in each sample.The low-performance groups displayed higher FBXW11-tv1 and FBXW11-tv2 transcript expressions than the normal performance groups.Two CpG islands were located within the 5’UTR and exon 1-2 region of the FBXW11 gene.Bisulfite sequencing PCR results demonstrated that the methylation levels of 11 methylation sites in the CpG island 2 from−99 to−43 in the normal performance groups were significantly lower than those in the low-performance groups.Pearson correlation analysis suggested that the CpG island 2 methylation level was negatively correlated with sperm motility and the transcript FBXW11-tv2 expression level.Our data revealed that alternative splicing and DNA methylation jointly regulated FBXW11 gene expression and were correlated with sperm quality traits during spermatogenesis in Holsteins. | YONG LIU ZHIHUA JU QIANG JIANG WENHAO LIU CHUNHONG YANG YARAN ZHANG XIUGE WANG YAPING GAO XIAOCHAO WEI YAN SUN JINPENG WANG MINGHAI HOU LING YANG JINMING HUANG | 2021 | BIOCELL2021,45,1: | 1 |

| 13 | Genome-wide identification of functional enhancers and their potential roles in pig breeding显示文摘Background:The pig is an economically important livestock species and is a widely applied large animal model in medical research.Enhancers are critical regulatory elements that have fundamental functions in evolution,development and disease.Genome-wide quantification of functional enhancers in the pig is needed.Results:We performed self-transcribing active regulatory region sequencing(STARR-seq)in the porcine kidney epithelial PK15 and testicular ST cell lines,and reliably identified 2576 functional enhancers.Most of these enhancers were located in repetitive sequences and were enriched within silent and lowly expressed genes.Enhancers poorly overlapped with chromatin accessibility regions and were highly enriched in chromatin with the repressive histone modification H3K9me3,which is different from predicted pig enhancers detected using ChIP-seq for H3K27ac or/and H3K4me1 modified histones.This suggests that most pig enhancers identified with STARR-seq are endogenously repressed at the chromatin level and may function during cell type-specific development or at specific developmental stages.Additionally,the PPP3CA gene is associated with the loin muscle area trait and the QKI gene is associated with alkaline phosphatase activity that may be regulated by distal functional enhancers.Conclusions:In summary,we generated the first functional enhancer map in PK15 and ST cells for the pig genome and highlight its potential roles in pig breeding. | Yinqiao Wu Yuedong Zhang Hang Liu Yun Gao Yuyan Liu Ling Chen Lu Liu David M.Irwin Chunhui Hou Zhongyin Zhou Yaping Zhang | 2022 | Journal of Animal Science and Biotechnology2022,13,6: | 1 |
| 14 | The acid cleaning method of labware for trace element analysis in snow and ice samples显示文摘Acid cleaning processes were performed on a class 100 laminar flow clean bench assembled inside a class 1000 clean room.The ultrapure water was produced by Millipore RO (Reverse Osmosis) and Milli-Q water purification systems.The three purity grades of nitric acid used for cleaning include Merck reagent grade HNO3,Fisher 'TraceMetal' grade HNO3,and the purest Fisher 'Optima' grade HNO3.The various bottles,containers and other labware,which are in contact with the samples,are made of low-density polyethylene (LDPE) and FEP or PFA Teflon materials.The acid cleaning procedures of the bottles and other containers follow a successive four times cleaning through immersion in increasing purity of nitric acid baths at different concentrations during four weeks.The first acid bath is performed at room temperature,but the following three acid baths are heated on ceramic hotplates with a surface temperature of 45℃.In order to verify the efficiency of the acid cleaning method,cleaned bottles underwent a blank determination procedure using ELAN 6100 inductively coupled plasma spectrometry (ICP-MS).Results show that most measured trace elements are not detected and the elements detected are at very low concentrations.The blank values are comparable with that of bottles cleaned at Korea Polar Research Institute (KOPRI).Although the acid cleaning method is developed mainly for reliable measurements of trace elements in snow and ice samples,it can also be used for investigations of trace elements in other environmental samples. | YaPing Liu ShuGui Hou YanCheng Zhang | 2009 | Research in Cold and Arid Regions2009,1,6: | 1 |
| 15 | Electron-ion collider in China显示文摘Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei.As a future high energy nuclear physics project,an Electron-ion collider in China(EicC)has been proposed.It will be constructed based on an upgraded heavy-ion accelerator,High Intensity heavy-ion Accelerator Facility(HIAF)which is currently under construction,together with a new electron ring.The proposed collider will provide highly polarized electrons(with a po-larization of 80%)and protons(with a polarization of 70%)with variable center of mass energies from 15 to 20 GeV and the luminosity of(2–3)×1033 cm^(−2)·s^(−1).Polarized deuterons and Helium-3,as well as unpolarized ion beams from Carbon to Uranium,will be also available at the EicC.The main foci of the EicC will be precision measurements of the structure of the nucleon in the sea quark region,including 3D tomography of nucleon;the partonic structure of nuclei and the parton interaction with the nuclear environment;the exotic states,especially those with heavy flavor quark contents.In addition,issues fundamental to understanding the origin of mass could be addressed by measurements of heavy quarkonia near-threshold production at the EicC.In order to achieve the above-mentioned physics goals,a hermetical detector system will be constructed with cutting-edge technologies.This document is the result of collective contributions and valuable inputs from experts across the globe.The EicC physics program complements the ongoing scientific programs at the Jefferson Laboratory and the future EIC project in the United States.The success of this project will also advance both nuclear and particle physics as well as accelerator and detector technology in China. | Daniele PAnderle Valerio Bertone Xu Cao Lei Chang Ningbo Chang Gu Chen Xurong Chen Zhuojun Chen Zhufang Cui Lingyun Dai Weitian Deng Minghui Ding Xu Feng Chang Gong Longcheng Gui Feng-Kun Guo Chengdong Han Jun He Tie-Jiun Hou Hongxia Huang Yin Huang KrešImir KumeričKi LPKaptari Demin Li Hengne Li Minxiang Li Xueqian Li Yutie Liang Zuotang Liang Chen Liu Chuan Liu Guoming Liu Jie Liu Liuming Liu Xiang Liu Tianbo Liu Xiaofeng Luo Zhun Lyu Boqiang Ma Fu Ma Jianping Ma Yugang Ma Lijun Mao Cédric Mezrag HervéMoutarde Jialun Ping Sixue Qin Hang Ren Craig DRoberts Juan Rojo Guodong Shen Chao Shi Qintao Song Hao Sun PawełSznajder Enke Wang Fan Wang Qian Wang Rong Wang Ruiru Wang Taofeng Wang Wei Wang Xiaoyu Wang Xiaoyun Wang Jiajun Wu Xinggang Wu Lei Xia Bowen Xiao Guoqing Xiao Ju-Jun Xie Yaping Xie Hongxi Xing Hushan Xu Nu Xu Shusheng Xu Mengshi Yan Wenbiao Yan Wencheng Yan Xinhu Yan Jiancheng Yang Yi-Bo Yang Zhi Yang Deliang Yao Zhihong Ye Peilin Yin C-PYuan Wenlong Zhan Jianhui Zhang Jinlong Zhang Pengming Zhang Yifei Zhang Chao-Hsi Chang Zhenyu Zhang Hongwei Zhao Kuang-Ta Chao Qiang Zhao Yuxiang Zhao Zhengguo Zhao Liang Zheng Jian Zhou Xiang Zhou Xiaorong Zhou Bingsong Zou Liping Zou | 2021 | Frontiers of physics2021,16,6: | 1 |
| 16 | Multi-Sinusoidal Waveform Shaping for Integrated Data and Energy Transfer in Aging Channels显示文摘Integrated data and energy transfer(IDET)is capable of simultaneously delivering on-demand data and energy to low-power Internet of Everything(Io E)devices.We propose a multi-carrier IDET transceiver relying on superposition waveforms consisting of multi-sinusoidal signals for wireless energy transfer(WET)and orthogonal-frequency-divisionmultiplexing(OFDM)signals for wireless data transfer(WDT).The outdated channel state information(CSI)in aging channels is employed by the transmitter to shape IDET waveforms.With the constraints of transmission power and WDT requirement,the amplitudes and phases of the IDET waveform at the transmitter and the power splitter at the receiver are jointly optimised for maximising the average directcurrent(DC)among a limited number of transmission frames with the existence of carrier-frequencyoffset(CFO).For the amplitude optimisation,the original non-convex problem can be transformed into a reversed geometric programming problem,then it can be effectively solved with existing tools.As for the phase optimisation,the artificial bee colony(ABC)algorithm is invoked in order to deal with the nonconvexity.Iteration between the amplitude optimisation and phase optimisation yields our joint design.Numerical results demonstrate the advantage of our joint design for the IDET waveform shaping with the existence of the CFO and the outdated CSI. | Jie Hu Yaping Hou Kun Yang | 2023 | China Communications2023,20,4: | 1 |

| 18 | Neuroprotection of a cocktail therapy involving anti-intercellular adhesion molecule 1 antibody and insulin-like growth factor 1 in treatment of cerebral ischemia/reperfusion injury in cats Nuclear magnetic resonance examination and pathological validatio显示文摘BACKGROUND: The pathophysiological mechanisms of ischemia are extremely complicated. It is difficult to confirm and maintain the therapeutic effects if only one neuroprotective agent is used. It is hypothesized that a cocktail therapy involving a combined application of neuroprotective agents is feasible and offers excellent therapeutic potential. OBJECTIVE: To evaluate the neuroprotective effects of a cocktail therapy of insulin-like growth factor 1 (IGF1) combined with anti-intercellular adhesion molecule 1 (ICAM1) antibody in the treatment of cerebral ischemia/reperfusion injury using medical imaging, pathology, and functional neurological deficit scoring techniques. DESIGN, TIME AND SETTING: This randomized, controlled, neuroimaging analysis of function and pathological observation was performed at the Laboratory of Molecular Imaging, Second Hospital, Hebei Medical University between September 2006 and December 2007. MATERIALS: Transient middle cerebral artery occlusion (MCAO) was induced in 24 healthy adult cats. Anti-ICAM1 antibody and IGF1 were sourced from the Shanghai Kangcheng Biological Product Co., Ltd., China. Stereotaxic apparatus was purchased from the Center for Medical Apparatus and Instruments, Shandong Liaocheng People’s Hospital, China. The in situ apoptosis kit was provided by the Beijing Zhongshan Biotechnique Co., Ltd., China. METHODS: Twenty-four cat models of MCAO were randomly divided into four groups (n = 6): control, IGF1, anti-ICAM1 antibody and cocktail therapy. Following a 2-hour ischemia and subsequent lateral cerebral ventricular puncture, 100 μg IGF1(cerebral ventricular), 100 μg anti-ICAM1 antibody (i.v.), 50 μg IGF1(lateral cerebral ventricular) + 50 μg anti-ICAM1 antibody (i.v.), and 100 μg physiological saline (i.v.) were administered to the IGF1, anti-ICAM1 antibody, cocktail therapy and control groups, respectively. On the following day, the same administration was performed again. MAIN OUTCOME MEASURES: Pathological observation of the cerebral dura mater tissue surrounding the MCAO target site was performed by electron microscopy. At days 3 and 7 following MCAO induction, the volume of the cerebral infarction was measured by Philips functional neurological deficit scoring and nuclear magnetic resonance imaging. RESULTS: Pathological observation revealed that the control group exhibited a great number of swollen neurons, glial cells and vascular endothelial cells, and showed severely injured mitochondria with an absence of the double membrane structure. The same phenomena were partially alleviated in the IGF1 and anti-ICAM1 antibody groups, and the most obvious alleviation of injuries was in the cocktail therapy group. At day 6 following MCAO establishment, the cocktail therapy group exhibited the smallest cerebral infarction volumes among the four groups (F = 71.322, P < 0.01). At days 3 and 7 following MCAO induction, the F value of Philips functional neurological deficit scoring was 10.398 and 14.430, respectively (P < 0.01); however, the best neurological functional recovery was in the cocktail therapy group. CONCLUSION: A cocktail therapy of IGF1 combined with anti-ICAM1 antibody produces better neuroprotective effects than IGF1 or anti-ICAM1 alone, as judged by injury to mitochondria and swelling in and around neurons and glial cells. | Huaijun Liu Liqun Yan Yaping Hou Shuochun Wu Dan He Linfang Li Yankai Wu BoyuanHuang Fei Yang | 2008 | Neural Regeneration Research2008,3,12: | 0 |
| 19 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 20 | Negative permittivity derived from inductive characteristic in the percolating Cu/EP metacomposites显示文摘Recently,increasing attention has been concentrated on negative permittivity with the development of the emerging metamaterials composed of periodic array structures.However,taking facile preparation into consideration,it is important to achieve negative permittivity behavior based on materials'intrinsic properties rather than their artificially periodic structures.In this paper,we proposed to fabricate the percolating composites with copper dispersed in epoxy(EP)resin by a polymerization method to realize the negative permittivity behavior.When Cu content in the composites reached to 80 wt%,the conductivity abruptly went up by three orders of magnitudes,suggesting a percolation behavior.Below the percolation threshold,the conductivity spectra conform to Jonscher's power law;when the Cu/EP composites reached to percolating state,the conductivity gradually reduced in high frequency region due to the skin effect.It is indicated that the conductive mechanism changed from hopping conduction to electron conduction.In addition,the permittivity did not increase monotonously with the increase of Cu content in the vicinity of percolation threshold,due to the presence of leakage current.Meanwhile,the negative permittivity conforming to Drude model was observed above the percolation threshold.Further investigation revealed that there was a constitutive relationship between the permittivity and the reactance.When conductive fillers are slightly above the percolation threshold,the inductive characteristic derived from conductive percolating network leads to the negative permittivity.Such epsilon-negative materials can potentially be applied in novel electrical devices,such as high-power microwave filters,stacked capacitors,negative capacitance field effect transistors and coil-free resonators.In addition,the design strategy based on percolating composites provides an approach to epsilon-negative materials. | Kai Sun Jiahao Xin Yaping Li Zhongyang Wang Qing Hou Xiaofeng Li Xinfeng Wu Runhua Fan Kwang Leong Choy | 2019 | Journal of Materials Science & Technology2019,35,11: | 0 |
