1The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5

3Petroleum coke conversion behavior in catalyst-assisted chemical looping combustion显示文摘Efficiently using petroleum coke as fuel and reducing carbon emission meanwhile have become attractive in oil processing industry.The paper is focused on the application of Chemical Looping Combustion(CLC)with petroleum coke,with the purpose of investigating its combustion performance and effects of potassium.Some experiments were performed in a laboratory scale fluidized bed facility with a natural manganese-based oxygen carrier.Experimental results indicated that the coke conversion is very sensitive to reaction temperature.The pre sent natural manganese-based oxygen carrier decorated by K has little effect on the improvement of coke conversion.XRD,SEM-EDX,and H2-TPR were adopted to characterize the reacted oxygen carrier samples.After being decorated by K,the oxygen carrier's capacity of transferring oxygen was decrea sed.A calcination temperature above the melting point of K2 CO3(891℃)shows better oxygen transfer reactivity in comparison to the one calcined at a lower temperature.The natural oxygen carrier used in the work has a high content of Si,which can easily react with K to form K(FeSi2 O6).Further,irrespective of reaction temperature,the coke conversion can be significantly enhanced by decorating the coke with K,with a demonstration of remarkably shorter reaction time,faster average coke gasification rate and higher average carbon conversion rate.Xianyu Liu Huijun Ge Shiwei Ma Shangyi Yin Ping Lu Laihong Shen Hongcun Bai Wei Wang Tao Song 2020Chinese Journal of Chemical Engineering2020,28,9:3

6The electromechanical features of LiNbO_(3) crystal for potential high temperature piezoelectric applications显示文摘Lithium niobate(LiNbO_(3),LN)crystal is a multi-functional material with favorable piezoelectric,nonlinear optical and electro-optic properties.In this study,the electromechanical properties of the radial extensional(RE)and the thickness extensional(TE)modes of the congruent LN are studied and the temperature dependent behaviors are revealed.The RE mode electromechanical coupling factors(kp)for the Y-and Z-oriented discs are calculated and found to be 3.8%and 24.7%,respectively,which are nearly the same as the experimental results of 3.8%and 25.2%,respectively.The maximum RE and thickness shear(TS)modes electromechanical coupling factors are obtained to be 47.6%and 68.5%for the Yx/25and Yx/167crystal cuts,respectively.The LN crystal possesses good temperature stability of the electromechanical coupling factors(RE and TE modes)from 20℃ to 500℃,where the variations of kp and kt for the Y-oriented discs are<8.0%and<1.8%,respectively.Feifei Chen Lingfeng Kong Wei Song Chao Jiang Shiwei Tian Fapeng Yu Lifeng Qin Xian Zhao 2019Journal of Materiomics2019,5,1:3
7A novel integrated non-targeted metabolomic analysis reveals significant metabolite variations between different lettuce (Lactuca sativa. L) varieties显示文摘Lettuce is an important leafy vegetable that represents a significant dietary source of antioxidants and bioactive compounds.However,the levels of metabolites in different lettuce cultivars are poorly characterized.In this study,we used combined GC×GC-TOF/MS and UPLC-IMS-QTOF/MS to detect and relatively quantify metabolites in 30 lettuce cultivars representing large genetic diversity.Comparison with online databases,the published literature,standards as well using collision cross-section values enabled putative identification of 171 metabolites.Sixteen of these 171 metabolites(including phenolic acid derivatives,glycosylated flavonoids,and one iridoid)were present at significantly different levels in leaf and head type lettuces,which suggested the significant metabolomic variations between the leaf and head types of lettuce are related to secondary metabolism.A combination of the results and metabolic network analysis techniques suggested that leaf and head type lettuces contain not only different levels of metabolites but also have significant variations in the corresponding associated metabolic networks.The novel lettuce metabolite library and novel non-targeted metabolomics strategy devised in this study could be used to further characterize metabolic variations between lettuce cultivars or other plants.Moreover,the findings of this study provide important insight into metabolic adaptations due to natural and human selection,which could stimulate further research to potentially improve lettuce quality,yield,and nutritional value.Xiao Yang Shiwei Wei Bin Liu Doudou Guo Bangxiao Zheng Lei Feng Yumin Liu Francisco A.Tomás-Barberán Lijun Luo Danfeng Huang 2018Horticulture Research2018,5,1:3
8A screening analysis of the GJB2 c.176 del 16 mutation responsible for hereditary deafness in a Chinese family显示文摘Objective:To determine whether a new-born child from a family carrying a deafness gene needs cochlear implantation to avoid dysphonia by screening and sequencing a deafness-related gene.Results:Both screening and sequencing results confirmed that the new born child had a normal GJB2 gene despite the fact that she has a brother suffering from hearing loss triggered by an allelic GJB2 c.176 del 16 mutation.We cloned the GJB2 genes derived from their respective blood genomic DNA into GFP fused plasmids and transfected those plasmids into the 293 T cell line to test for gene function.While the mutated GJB2gene(GJB2 c.176 del 16) of her deaf brother was found to be unable to form the gap junction structure between two adjacent cells,the baby girl's GJB2 gene ran into no such problems.Conclusion:The screening and sequencing as well as the GJB2 gene function tests invariably showed results consistent with the ABR tested hearing phenotype,which means that the child,with a normal wild type GJB2 gene,does not need early intervention to prevent her from developing hearing loss and dysphonia at a later stage in life.Hao Jiang Xi Shi Shiwei Qiu Yanfen Dong Yuehua Qiao Dongzhi Wei 2016Journal of Otology2016,11,3:2
9Hearing analysis in heterozygous and homozygous klotho gene deficient mice显示文摘Objective: To understand the crucial role of the klotho gene in hearing development in mouse models.Methods: PCR was used to identify CBA mice with different genotypes, i.e. WT, heterozygous(klotho +/-)or homozygous(klotho-/-). Mice phenotype and weight were recorded postnatal 25 days(P-25) and auditory brainstem responses(ABR) were used to determine auditory function at P-60.Results: klotho-/-mice tended to have smaller size, lighter weight and higher ABR thresholds at P-60,showing early onset age-related hearing loss(ARHL).Conclusion: Heterozygous and homozygous klotho deficient mice exhibit different degrees of hearing loss at young age, with homozygous mice(klotho-/-) showing more severe hearing loss. Our results indicate that persisted expression of klotho protein in the inner ear may potentially delay the onset of ARHL and play an important role in the protection of auditory function.Na Yuan Shiwei Qiu Qian Wang Wei Zhuang Guoping Li Tiantian Sun Shiming Yang Yuehua Qiao Xi Shi 2018Journal of Otology2018,13,4:2
10Increased Expression of Colonic Mucosal Melatonin in Patients with Irritable Bowel Syndrome Correlated with Gut Dysbiosis显示文摘Dysregulation of the gut microbiota/gut hormone axis contributes to the pathogenesis of irritable bowel syndrome(IBS).Melatonin plays a beneficial role in gut motility and immunity.However,altered expression of local mucosal melatonin in IBS and its relationship with the gut microbiota remain unclear.Therefore,we aimed to detect the colonic melatonin levels and microbiota profiles in patients with diarrhea-predominant IBS(IBS-D)and explore their relationship in germ-free(GF)rats and BON-1 cells.Thirty-two IBS-D patients and twenty-eight healthy controls(HCs)were recruited.Fecal specimens from IBS-D patients and HCs were separately transplanted into GF rats by gavage.The levels of colon mucosal melatonin were assessed by immunohistochemical methods,and fecal microbiota communities were analyzed using 16S rDNA sequencing.The effect of butyrate on melatonin synthesis in BON-1 cells was evaluated by ELISA.Melatonin levels were significantly increased and negatively correlated with visceral hypersensitivity in IBS-D patients.GF rats inoculated with fecal microbiota from IBS-D patients had high colonic melatonin levels.Butyrate-producing Clostridium cluster XIVa species,such as Roseburia species and Lachnospira species,were positively related to colonic mucosal melatonin expression.Butyrate significantly increased melatonin secretion in BON-1 cells.Increased melatonin expression may be an adaptive protective mechanism in the development of IBS-D.Moreover,some Clostridium cluster XIVa species could increase melatonin expression via butyrate production.Modulation of the gut hormone/gut microbiota axis offers a promising target of interest for IBS in the future.Ben Wang Shiwei Zhu Zuojing Liu Hui Wei Lu Zhang Meibo He Fei Pei Jindong Zhang Qinghua Sun Liping Duan 2020Genomics, Proteomics & Bioinformatics2020,18,6:2
11High temperature performance of coaxial h-BN/CNT wires above 1,000 ℃:Thermionic electron emission and thermally activated conductivity显示文摘The development of wires and cables that can tolerate extremely high temperatures will be very important for probing extreme environments, such as in solar exploration, fire disasters, high-temperature materials processing, aeronautics and astronautics. In this paper, a lightweight high-temperature coaxial h-boron nitride (BN)/carbon nanotube (CNT) wire is synthesized by the chemical vapor deposition (CVD) epitaxial growth of h-BN on CNT yarn. The epitaxially grown h-BN acts as both an insulating material and a jacket that protects against oxidation. It has been shown that the thermionic electron emission (1,200 K) and thermally activated conductivity (1,000 K) are two principal mechanisms for insulation failure of h-BN at high temperatures. The thermionic emission of h-BN can provide the work function of h-BN, which ranges from 4.22 to 4.61 eV in the temperature range of 1,306-1,787 K. The change in the resistivity of h-BN with temperature follows the ohmic conduction model of an insulator, and it can provide the “electron activation energy”(the energy from the Fermi level to the conduction band of h-BN), which ranges from 2.79 to 3.08 eV, corresponding to a band gap for h-BN ranging from 5.6 to 6.2 eV. However, since the leakage current is very small, both phenomena have no obvious influence on the signal transmission at the working temperature. This lightweight coaxial h-BN/CNT wire can tolerate 1,200 ℃ in air and can transmit electrical signals as normal. It is hoped that this lightweight high-temperature wire will open up new possibilities for a wide range of applications in extreme high-temperature conditions.Xinhe Yang Peng Liu Duanliang Zhou Feng Gao Xinhe Wang Shiwei Lv Zi Yuan Xiang Jin Wei Zhao Haoming Wei Lina Zhang Jiandong Gao Qunqing Li Shoushan Fan Kaili Jiang 2019Nano Research2019,12,8:2
12Plowing-Extrusion Processes and Performance of Functional Surface Structures of Copper Current Collectors for Lithium-Ion Batteries显示文摘Most copper current collectors for commercial lithium-ion batteries(LIBs)are smooth copper foils,which cannot form a stable and effective combination with electrode slurry.They are likely to deform or fall off after long-term operation,resulting in a sharp decline in battery performance.What is worse is that this condition inevitably causes internal short circuits and thus brings about security risks.In this study,a process route of fabricating the functional surface structures on the surface of a copper collector for LIBs by twice-crisscross micro-plowing(TCMP)is proposed,which provides a new idea and an efficient method to solve the above problems from the perspective of manufacturing.The finite element simulation of TCMP combined with the cutting force test and morphological characterization is conducted to verify the forming mechanism of the surface structures on a copper sheet and its relationship with the processing parameters.The influence of several key processing parameters on the surface characteristics of the copper sheet is comprehensively explored.A series of functions is tested to obtain the optimal parameters for performance improvement of the current collector.Results show that the structured copper sheet with the cutting distance of 250μm,cutting depth of 80μm,and cutting crossing angle of 90°enables the best surface features of the current collector;the contact angle reaches 0°,the slurry retention rate is up to 89.2%,and the friction coefficient reaches 0.074.The battery using the as-prepared structured copper sheet as the current collector produces a specific capacity of 318.6 mAh/g after 50 cycles at a current density of 0.2 C,which is 132.7%higher than the one based on a smooth surface.The capacity reversibility of the sample with the new current collector is much better than that of the traditional samples,yielding a lower impedance.Chun Wang Wei Yuan Yu Chen Bote Zhao Yong Tang Shiwei Zhang Xinrui Ding Jun He Songmao Chen Baoyou Pan Mingyue Chen 2022Nanomanufacturing and Metrology2022,5,4:2
13Upregulation of GLT25D1 in Hepatic Stellate Cells Promotes Liver Fibrosis via the TGF-β1/SMAD3 Pathway In Vivo and In vitro显示文摘Background and Aims:Collagenβ(1-O)galactosyltransferase 25 domain 1(GLT25D1)is associated with collagen production and glycosylation,and its knockout in mice results in embryonic death.However,its role in liver fibrosis remains elusive,particularly in hepatic stellate cells(HSCs),the primary collagen-producing cells associated with liver fibrogenesis.Herein,we aimed to elucidate the role of GLT25D1 in HSCs.Methods:Bile duct ligation(BDL)-induced mouse liver fibrosis models,primary mouse HSCs(mHSCs),and transforming growth factor beta 1(TGF-β1)-stimulated LX-2 human hepatic stellate cells were used in in vivo and in vitro studies.Stable LX-2 cell lines with either GLT25D1 overexpression or knockdown were established using lentiviral transfection.RNA-seq was performed to investigate the genomic differences.HPLCMS/MS were used to identify glycosylation sites.Scanning electronic microscopy(SEM)and second-harmonic generation/two-photon excited fluorescence(SHG/TPEF)were used to image collagen fibril morphology.Results:GLT25D1 expression was upregulated in nonparenchymal cells in human cirrhotic liver tissues.Meanwhile,its knockdown attenuated collagen deposition in BDL-induced mouse liver fibrosis and inhibited mHSC activation.GLT25D1 was overexpressed in activated versus quiescence LX-2 cells and regulated in vitro LX-2 cell activation,including proliferation,contraction,and migration.GLT25D1 also significantly increased liver fibrogenic gene and protein expression.GLT25D1 upregulation promoted HSC activation and enhanced collagen expression through the TGF-β1/SMAD signaling pathway.Mass spectrometry showed that GLT25D1 regulated the glycosylation of collagen in HSCs,affecting the diameter of collagen fibers.Conclusions:Collectively,the upregulation of GLT25D1 in HSCs promoted the progression of liver fibrosis by affecting HSCs activation and collagen stability.Shiwei Wang Lingling He Fan Xiao Meixin Gao Herui Wei Junru Yang Yang Shu Fuyang Zhang Xiaohui Ye Ping Li Xiaohua Hao Xingang Zhou Hongshan Wei 2023Journal of Clinical and Translational Hepatology2023,11,1:1

16A Photoelectric-Stimulated MoS_(2) Transistor for Neuromorphic Engineering显示文摘The von Neumann bottleneck has spawned the rapid expansion of neuromorphic engineering and brain-like networks.Synapses serve as bridges for information transmission and connection in the biological nervous system.The direct implementation of neural networks may depend on novel materials and devices that mimic natural neuronal and synaptic behavior.By exploiting the interfacial effects between MoS_(2) and AlOx,we demonstrate that an h-BN-encapsulated MoS_(2) artificial synapse transistor can mimic the basic synaptic behaviors,including EPSC,PPF,LTP,and LTD.Efficient optoelectronic spikes enable simulation of synaptic gain,frequency,and weight plasticity.The Pavlov classical conditioning experiment was successfully simulated by electrical tuning,showing associated learning behavior.In addition,h-BN encapsulation effectively improves the environmental time stability of our devices.Our h-BN-encapsulated MoS_(2) artificial synapse provides a new paradigm for hardware implementation of neuromorphic engineering.Shuiyuan Wang Xiang Hou Lan Liu Jingyu Li Yuwei Shan Shiwei Wu David Wei Zhang Peng Zhou 2019Research2019,,1:1
17Realizing Zinc Blende GaAs/AlGaAs Axial and Radial Heterostructure Nanowires by Tuning the Growth Temperature显示文摘Vertical zinc blende GaAs/AlGaAs heterostructure nanowires were grown at different temperatures by metalorganic chemical vapor deposition via Au-assisted vapor-liquid-solid mechanism.It was found that radial growth can be enhanced by increasing the growth temperature.The growth of radial heterostructure can be realized at temperature higher than 500℃,while the growth temperature of axial heterostructure is lower than 440℃.The room temperature photoluminescence properties of the nanowires were investigated and the relevant growth mechanism was discussed.Jingwei Cuo Hui Huang Xiaomin Ren Xin Yan Shiwei Cai Wei Wang Yongqing Huang Qi Wang and Xi 2011Journal of Materials Science & Technology2011,27,6:1

20Hierarchical NiMoP_(2)-Ni_(2)P with amorphous interface as superior bifunctional electrocatalysts for overall water splitting显示文摘Producing highly efficient bifunctional catalyst for the generation of hydrogen and oxygen through overall water splitting is an emerging direction in electrocatalysis.Herein,a dandelion-like hierarchical NiMoP_(2)-Ni_(2)P(nanowire/nanoparticle)heterostructure was synthesized for efficient electrochemical water splitting.The NiMoP_(2)-Ni_(2)P heterostructures grown on carbon cloth as a freestanding integrated electrode exhibited excellent oxygen evolution reaction(OER)activity and hydrogen evolution reaction(HER)activities with low overpotentials(258 mV and 53 mV to reach 10 mA cm~(-2)for the OER and HER,respectively),and small Tafel slope(45 mV dec^(-1)and 58 mV dec^(-1)for the OER and HER,respectively).Moreover,the NiMoP_(2)-Ni_(2)P heterostructure can act as both anode and cathode catalysts for overall water splitting with low overall potential of 1.48 V at 10 mA cm~(-2).Density functional theory(DFT)combined with structural probes suggests that the amorphous heterogeneous interfaces play an essential role in enhanced catalytic performance.Gaoqi Tian Songrui Wei Zhangtao Guo Shiwei Wu Zhongli Chen Fuming Xu Yang Cao Zheng Liu Jieqiong Wang Lei Ding Jinchun Tu Hao Zeng 2021Journal of Materials Science & Technology2021,,18:1
