| 1 | An atomic force microscopy study of coal nanopore structure显示文摘Coal nanopore structure is an important factor in understanding the storage and migration of absorbed gas in coal. A new method for studying coal nanopore structures is proposed. This idea is based on the nano-level resolution of atomic force microscopy, which can be employed to observe the structural features of coal nanopores clearly, conduct quantitative three-dimensional measurements and obtain structural parameters. Analysis results show that coal nanopores are mainly metamorphic pores and intermolecular pores. The metamorphic pores are commonly rounded and elliptical, increasing quantitatively with the coalification degree. The forms of intermolecular pores change markedly. The average pore size of low-rank coal is bigger than high-rank coal, and the number of intermolecular pores decreases as the coal rank increases. Section analysis effectively characterizes the coal pore microstructure, bearing analysis is a vital approach to measure microporosity, and grain analysis can be employed to study the pore size distribution. Atomic force microscopy is a tool for the in-depth research of coal pore microstructure and the coal-bed methane adsorption mechanism. | YAO SuPing JIAO Kun ZHANG Ke HU WenXuan DING Hai LI MiaoChun PEI WenMing | 2011 | Chinese Science Bulletin2011,56,25: | 30 |

| 3 | Roles of Fas signaling pathway in vitamin E succinateinduced apoptosis in human gastric cancer SGC-7901 cells显示文摘AIM: To investigate the roles of Fas signaling pathway in vitamin E succinate-induced apoptosis in human gastric cancer SGC-7901 cells.METHODS: Human gastric cancer SGC-7901 cells were treated with VES at 5, 10, 20 mg@L-1, succinic acid and vitamin E as vehicle control and condition media only as untreated (UT) control. Apoptotic morphology was observed by DAPI staining. Western blot analysis was applied to measure the expression of Fas, FADD and caspase-8 proteins. After the cells were transiently transfected with Fas and FADD antisense oligonucleotides, respectively, caspase-8 activity was determined by flurometric method.RESULTS: The morphologically apoptotic changes were observed after VES treatment by DAPI staining. 23.7 % and 89.6 % apoptosis occurred after 24 h and 48 h of 20 mg@L-1 VES treatment, respectively. The protein levels of Fas, FADD and caspase-8 were evidently increased in a dose-dependent manner after 24 h of VES treatment. The blockage of Fas by transfection with Fas antisense oligonucleotides obviously inhibited the expression of FADD protein. After SGC-7901 cells were transfected with Fas and FADD antisense oligonucleotides, caspase-8 activity was obviously decreased (P<0.01), whereas Fas blocked more than FADD.CONCLUSION: VES-induced apoptosis in human gastric cancer SGC-7901 cells involves Fas signaling pathway including the interaction of Fas, FADD and caspase-8. | Kun Wu Yao Li Yan Zhao Yu-Juan Shah Wei Xia Lan Zhao,Department of Nutrition and Food Hygiene,Public Health School,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Wei-Ping Yu,Genetics Institute,Texas University of USA,Austin,USA | 2002 | World Journal of Gastroenterology2002,8,6: | 30 |
| 4 | A novel gene delivery system targeting cells expressing VEGF receptors显示文摘Two ligand oligopeptides GV1 and GV2 were designed according to the putative binding region of VEGF to its receptors. GV1, GV2 and endosome releasing oligopeptide HA20 were conjugated with poly-L-lysine or protamine and the resulting conjugates could interact with DNA in a noncovalent bond to form a complex. Using pSV2-β-galactosidase as a reporter gene, it has been demonstrated that exogenous gene was transferred into bovine aortic arch-derived endothelial cells (ABAE) andhuman malignant melanoma cell lines (A375) in vitro. In vivo experiments, exogenous gene was transferred into tumor vascular endothelial cells and tumor cells of subcutaneously transplanted human colon cancer LOVO, human malignant melanoma A375 and human hepatoma graft in nude mice. This system could also target gene to intrahepatically transplanted human hepatoma injected via portal vein in nude mice. These results are correlated with theGene delivery system targeting VEGF receptors relevant receptors (flt-1, flk-1/KDR) expression on the targeted cells and tissues. | LI JUN MIN JUN SONG HAN YI HUANG PEI KUN TIAN SHU MIN QU MIN YAO HUI QIU JIANG DA FANG WAN JING CHU LUO CHENG XIAO GU JIAN REN GU( National Labomtory for Oncogenes and Related Genes, Shanghai Cancer Institute, Shanghai 200032,China)(National Laboratory of | 1999 | Cell Research1999,9,1: | 22 |
| 5 | Preparation of Artificial Antigen and Egg Yolk-derived Immunoglobulin(IgY) of Citrinin for Enzyme-Linked Immunosorbent Assay显示文摘To prepare artificial antigens and anti-citrinin egg yolk-derived immunoglobulin(IgY) to build an enzyme-linked immunosorbent assay(ELISA) for citrinin(CTN).Methods CTN was conjugated with bovine serum albumin(BSA),ovalbumin(OVA) with formaldehyde condensation method to prepare artificial antigens and identified by ultraviolet(UV) spectrometry and Infrared(IR) spectrometry.Artificial antigens for CTN and anti-CTN IgY were purified with polyethylene glycol two-step precipitation method and identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE).ELISA with IgY was established.Cross-reactivity of IgY with various structural similarities to CTN and possible co-occurrence with CTN in agricultural commodities were studied.Results UV and IR absorption spectra suggested that CTN was correlated with the carrier protein of BSA or OVA.SDS-PAGE patterns showed that the anti-CTN IgY was almost pure with a molecular weight of approximate 100 KD.The indirect competitive ELISA showed that the detection limit of CTN was 10 ng·mL-1,with a good linearity ranging 20-640 ng·mL-1.Conclusion Artificial antigens of CTN can be successfully synthesized.The established ELISA can be used to determine CTN-contaminated samples. | ZHAO-HUI DUAN ZHUANG-SEN LIN HE-RUI YAO YAN-HONG GAO KUN ZHANG Su-QING ZHAO ZHEN-YU ZHU | 2009 | Biomedical and Environmental Sciences2009,22,3: | 21 |
| 6 | Complete chloroplast genome sequence of Magnolia grandiflora and comparative analysis with related species显示文摘Magnolia grandiflora is an important medicinal,ornamental and horticultural plant species.The chloroplast(cp) genome of M.grandiflora was sequenced using a 454 sequencing platform and the genome structure was compared with other related species.The complete cp genome of M.grandiflora was 159623 bp in length and contained a pair of inverted repeats(IR) of 26563 bp separated by large and small single copy(LSC,SSC) regions of 87757 and 18740 bp,respectively.A total of 129 genes were successfully annotated,18 of which included introns.The identity,number and GC content of M.grandiflora cp genes were similar to those of other Magnoliaceae species genomes.Analysis revealed 218 simple sequence repeat(SSR) loci,most composed of A or T,contributing to a bias in base composition.The types and abundances of repeat units in Magnoliaceae species were relatively conserved and these loci will be useful for developing M.grandiflora cp genome vectors.In addition,results indicated that the cp genome size in Magnoliaceae species and the position of the IR border were closely related to the length of the ycf1 gene.Phylogenetic analyses based on 66 shared genes from 30 species using maximum parsimony(MP) and maximum likelihood(ML) methods provided strong support for the phylogenetic position of Magnolia.The availability of the complete cp genome sequence of M.grandiflora provides valuable information for breeding of desirable varieties,cp genetic engineering,developing useful molecular markers and phylogenetic analyses in Magnoliaceae. | LI XiWen GAO HuanHuan WANG YiTao SONG JingYuan HENRY Robert WU HeZhen HU ZhiGang YAO Hui LUO HongMei LUO Kun PAN HongLin CHEN ShiLin | 2013 | Science China(Life Sciences)2013,56,2: | 17 |
| 7 | Effect of Qingfei Mixture (清肺合剂) on Pediatric Mycoplasma Pneumoniae Pneumonia with Phlegm Heat Obstructing Fei (Lung) Syndrome显示文摘Objective: To explore the effect and mechanism of Qingfei Mixture(清肺合剂), a Chinese medicine, in treating mycoplasma pneumonia(MP) in MP patients and rat model. Methods: A total of 46 MP children with phlegm heat obstructing Fei(Lung) syndrome were randomly assigned to two groups by the method of random number table, with 23 children in each group. The control group was treated with intravenous infusion of azithromycin; the treatment group received intravenous infusion of azithromycin and oral administration of Qingfei Mixture. The treatment course was 7 days. Major symptoms and minor symptoms were observed and scored before and after treatments. A rat model of MP was also established. A total of 120 wistar rats were randomly divided into 5 groups: a normal group, infection group, Qingfei Mixture treatment group, azithromycin treatment group, and Qingfei Mixture + azithromycin treatment group. Each group contained 24 rats, from which every 6 were euthanatized 1, 3, 7 and 14 days after infection. MP DNA in pulmonary tissue homogenates was detected using real-time fluorescence quantitative polymerase chain reaction. Pathology was assessed after hematoxylin(HE) staining and lung tissue pathology scores were determined in pulmonary tissue. Transmission electron microscopic detection and electronic image analysis were performed on lung tissue 3 days after infection. Interleukin(IL)-17 was detected in serum using enzymelinked immunosorbent assay(ELISA) 7 days after infection. Results: In the clinical study, both control and the treatment group showed improved results on removing symptoms of phlegm heat syndrome compared to the control group(P<0.05). In animal experiments, On the 7th day after MP infection, as detected by electron microscopy, the pulmonary capillary basement membranes of the azithromycin + Qingfei Mixture treatment group were much thinner than those of the azithromycin or Qingfei mixture treatment groups(P<0.05). The level of serum IL-17 in the azithromycin + Qingfei Mixture treatment group was lower than that in the azithromycin or Qingfei Mixture groups(P<0.01). Conclusion: Both Qingfei Mixture and azithromycin have therapeutic effects on mycoplasma pneumoniae pneumonia, but the combination of both agents had the greatest effect. | YANG Ai-jun XI Kun YAO Yan-qing DING Ying-xue YANG Li-jun CUI Hong | 2017 | Chinese Journal of Integrative Medicine2017,23,9: | 15 |
| 8 | Antioxidant 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 | 2019 | Biomedical and Environmental Sciences2019,32,1: | 14 |
| 9 | Comparing the effects of depression,anxiety,and comorbidity on quality-of-life,adverse outcomes,and medical expenditure in Chinese patients with acute coronary syndrome显示文摘Background:Depression and anxiety have been correlated with elevated risks for quality-of-life (QOL),adverse outcomes,and medical expenditure in patients with acute coronary syndrome (ACS).However,the relevant data are lacking for Chinese ACS populations,especially regarding different effects of major depression,anxiety,and comorbidity.The objective of this study was to evaluate the dynamic changes of depression and/or anxiety over 12 months and examine the effects of depression,anxiety,and comorbidity on QOL,adverse outcomes,and medical expenditure in Chinese patients with ACS.Methods:For this prospective longitudinal study,a total of 647 patients with ACS were recruited from North China between January 2013 and June 2015.Among them,531 patients (82.1%) completed 12-month follow-ups.Logistic regression model was utilized for analyzing the association of baseline major depression,anxiety,and comorbidity with 12-month all-cause mortality,cardiovascular events,QOL,and health expenditure.Results:During a follow-up period of 12 months,7.3% experienced non-fatal myocardial infarction (MI) and 35.8% cardiac rehospitalization.Baseline comorbidity,rather than major depression/anxiety,strongly predicted poor 12-month QOL as measured by short-form health survey-12 (odds ratio [OR]:1.77,95% confidence interval [CI]:1.22–2.52,P = 0.003).Regarding 12-month non-fatal MI and cardiac re-hospitalization,baseline anxiety (OR:2.83,95% CI:1.33–5.89,P<0.01;OR:4.47,95% CI:1.50–13.00,P<0.01),major depression (OR:2.58,95% CI:1.02–6.15,P<0.05;OR:5.22,95% CI:1.42–17.57,P<0.03),and comorbidity (OR:6.33,95% CI:2.96–13.79,P<0.0001,OR:14.08,95% CI:4.99–41.66,P<0.0001) were all independent predictors,and comorbidity had the highest predictive value.Number of re-hospitalization stay,admission frequency within 12 months and medical expenditure within 2 months were the highest in patients with ACS with comorbidity.Conclusions:Major depression and anxiety may predict 12-month non-fatal MI and cardiac re-hospitalization.However,comorbidity has the highest predictive value with greater medical expenditure and worse QOL in Chinese patients with ACS.And depression with comorbid anxiety may be a new target of mood status in patients with ACS. | Kun Xia Le-Feng Wang Xin-Chun Yang Hong-Yan Jiang Li-Jing Zhang Dao-Kuo Yao Da-Yi Hu Rong-Jing Ding | 2019 | Chinese Medical Journal2019,,9: | 13 |
| 10 | Gold nanorods together with HSP inhibitor-VER-155008 micelles for colon cancer mild-temperature photothermal therapy显示文摘Enhancing the heat-sensitivity of tumor cells provides an alternative solution to maintaining the therapeutic outcome of photothermal therapy(PTT). In this study, we constructed a therapeutic system, which was composed of methoxy-polyethylene-glycol-coated-gold-nanorods(MPEG-AuN R) and VER-155008-micelles, to evaluate the effect of VER-155008 on the sensitivity of tumor cells to heat, and further investigate the therapeutic outcome of MPEG-AuN R mediated PTT combined with VER-155008-micelles. VER-155008-micelles downregulate the expression of heat shock proteins and attenuate the heat-resistance of tumor cell. The survival of HCT116 cells treated with VER-155008-micelles under 45 ℃ is equal to that treated with high temperature hyperthermia(55 ℃) in vitro. Furthermore, we proved either the MPEG-AuN R or VER-155008-micelles can be accumulate in the tumor site by photoacoustic imaging and fluorescent imaging. In vivo anti-cancer evaluation showed that tumor size remarkably decreased(smaller than 100 mm^3 or vanished) when treated with combing 45℃ mild PTT system, which contrasted to the tumor size when treated with individual 45℃ mild PTT(around 500nm^3) or normal saline as control(larger than 2000 nm^3). These results proved that the VER-155008-micelles can attenuate the heat-resistance of tumor cells and enhance the therapeutic outcome of mild-temperature photothermal therapy. | Xichuan Tang Liwei Tan Kun Shi Jinrong Peng Yao Xiao Wenting Li Lijuan Chen Qian Yang Zhiyong Qian | 2018 | Acta Pharmaceutica Sinica B2018,8,4: | 12 |
| 11 | 4 K high frequency pulse tube cryocooler used for terahertz space application显示文摘Terahertz(THz) frequency region, defined from0.1 to 10 THz, is an important frequency band for radio astronomy and atmospheric science. As NbN Superconductor-Insulator-Superconductor(SIS) mixers used for terahertz detection, which are studied by the Purple Mountain Observatory(PMO), Chinese Academy of Sciences(CAS), work at 8–10 K, and require condition of micro vibrations, its astronomical observation in aerospace is limited by suitable refrigeration method. 4 K high frequency pulse tube cryocooler developed by Key Laboratory of Space Energy Conversion Technologies(SECT), Technical Institute of Physics and Chemistry(TIPC), CAS, offers an opportunity for the application of SIS mixers. This article introduces the progress of the two-stage high frequency pulse tube cryocooler researched by TIPC. The cryocooler has reached a no load temperature of 4.5 K which is the lowest temperature for this kind of cryocooler reported so far. The successful coupling between the THz component and the high frequency pulse tube cryocooler lays a solid foundation for space detection in the terahertz band. | Jia Quan Yanjie Liu Dong Liu Kun Zhang Jingtao Liang Jing Li Qijun Yao Shengcai Shi | 2014 | Chinese Science Bulletin2014,59,27: | 12 |
| 12 | Computational Prediction and Identification of Epstein-Barr Virus Latent Membrane Protein 2A Antigen-Specific CD8^+ T-Cell Epitopes显示文摘Epstein-Barr virus (EBV) associated nasopharyngeal carcinoma (NPC) is a high incidence tumor in Southeast Asia. Among EBV encoded proteins, latent membrane protein 2A (LMP2A) is an important antigen for T cell therapy of EBV. In this study, we predicted six HLA-A2 restricted CTL candidate epitopes of LMP2A by SYFPEITHI, NetMHC and MHCPred methods combined with the polynomial method. Subsequently, biological functions of these peptides were tested by experiments in vitro. In ELISPOT assay, the positive response of the LMP2A specific CTL stimulated by three (LMP2A264-272, LMP2A426-434 and LMP2A356-364) of six peptides respectively showed that the numbers of spots forming cells (SFC) ranged from 55.7 to 80.6 SFC/5 × 104 CD8+ T cells and the responding index (RI) ranged from 5.4 to 7. These three epitope-specific CTLs could effectively kill specific HLA-A2-expressing target cells. As a result, LMP2A264-272 (QLSPLLGAV), LMP2A426-434 (CLGGLLTMV) and LMP2A356-364 (FLYALALLL) were identified as LMP2A-specific CD8+ T-cell epitopes. It would be useful to clarify immune response toward EBV and to develop a vaccine against EBV-correlative NPC. | Bing Wang Kun Yao Genyan Liu Fangyi Xie Feng Zhou Yun Chen | 2009 | Cellular & Molecular Immunology2009,6,2: | 11 |
| 13 | Comparative Immunization in BALB/c Mice with Recombinant Replication-Defective Adenovirus Vector and DNA Plasmid Expressing a SARS-CoV Nucleocapsid Protein Gene显示文摘In order to investigate immunogenicity in the induction of humoral and cellular immune responses, severe acute respiratory syndrome associated coronavirus (SARS-CoV)-N gene recombinant replication-defective adenoviral vector, rAd-N, was generated and immunized BALB/c mice in a pcDNA3.1-N prime-rAd-N boost regimen. After humoral and cellular immune response detection, different levels of SARS-CoV N protein specific antibodies and interferon-γ (IFN-γ) secretion are shown compared to controls. The humoral immune response was induced more effectively by the DNA priming and recombinant adenovirus boosting regimen. There is a significant difference between heterogeneous and homologous vaccinations. The heterogeneous combinations were all higher than those of the homologous combinations in the induction of anti-N antibody response. Among the three heterogeneous combinations, pcDNA3.1-N/pcDNA3.1-N/pcDNA3.1-N/rAd-N induced the strongest antibody response. In the induction of IFN-γ production, the homologous combination of rAd-N/rAd-N/rAd-N/rAd-N was significantly stronger than that of pcDNA3.1-N/pcDNA3.1-N/pcDNA3.1-N/pcDNA3.1-N, but was relatively weaker than the heterogeneous combination of pcDAN3.1-N/pcDAN3.1-N/pcDAN3.1-N/rAd-N. This combination was a most efficient immunization regimen in induction of SARS-CoV-N-specific (IFN-γ) secretion just as the antibody response. These results suggest that DNA immunization followed by recombinant adenovirus boosting could be used as a potential SARS-CoV vaccine. | Chunling Ma Kun Yao Feng Zhou Minsheng Zhu | 2006 | Cellular & Molecular Immunology2006,3,6: | 10 |
| 14 | WATER TUNNEL EXPERIMENTAL INVESTIGATION ON THE DRAG REDUCTION CHARACTERISTICS OF THE TRAVELING WAVY WALL显示文摘Drag reduction experiment of the traveling wavy wall at high Reynolds number is conducted.A suit of traveling wavy wall device is developed.The drag forces of the traveling wavy wall with various wave speeds(c)are measured under different water speeds(U)in the K15 cavitation water tunnel and are compared with that of the flat plate.The results show that the mean drag force of the traveling wavy wall have decreased and then increased with oscillation frequency increasing at the same flow speed.Under different flow speeds,when traveling wave wall reached to the minimum of drag force,the corresponding the ratio of the wall motion phase speed c to flow speed U,c /U is slightly different.Within the parameters of the experiment,whenc /U reaches a certain value,the drag force of the traveling wavy wall can be less than that of the flat plate.The drag reduction can be up to 42%.Furthermore,as the value ofc /U increases,the traveling wavy wall can restrain the separation and improve the quality of flow field. | YAO Yan LU Chuan-jing SI Ting ZHU Kun | 2011 | Journal of Hydrodynamics2011,23,1: | 10 |
| 15 | A Novel Single Phase Grounding Fault Protection Scheme Without Threshold Setting for Neutral Ineffectively Earthed Power Systems显示文摘The setting values of thresholds for fault feature parameters are critical in all kinds of protection schemes.When the detected feature parameter value exceeds the setting value,the protection will trip.However,the setting value based conventional protection schemes sometimes cannot satisfy the protection requirements of neutral ineffectively earthed power systems(NIEPS)due to wide variations in operating conditions and the complexities of fault cases.In this paper,a novel single phase grounding fault protection scheme without threshold setting is proposed.The fault detection is achieved based on operating states rather than setting values.A fuzzy c-means algorithm is used to divide the operating state of the protected feeder into non-fault states and fault states.The cluster center of each state is then obtained by classifying the historical feature samples of the protected feeder extracted under various operating conditions into their corresponding states in a constructed multi-dimensional fault feature space.The distances between the detected feature samples and the cluster centers of the non-fault and the fault states are calculated.If the distance to the fault state is shorter than that to the non-fault state,a fault is detected.Otherwise,the feeder is considered normal.A PSCAD/EMTDC simulator is used to simulate a 35 kV NIEPS under various operating conditions,non-linear loads,and complex fault cases.Results show that the proposed single phase grounding fault protection scheme without threshold setting can protect the system correctly under all kinds of faults. | Xiangjun Zeng Kun Yu Yuanyuan Wang Yao Xu | 2016 | CSEE Journal of Power and Energy Systems2016,2,3: | 9 |

| 19 | Salivary mycobiome dysbiosis and its potential impact on bacteriome shifts and host immunity in oral lichen planus显示文摘The biodiversity of the mycobiome,an important component of the oral microbial community,and the roles of fungal–bacterial and fungal–immune system interactions in the pathogenesis of oral lichen planus (OLP) remain largely uncharacterized.In this study,we sequenced the salivary mycobiome and bacteriome associated with OLP.First,we described the dysbiosis of the microbiome in OLP patients,which exhibits lower levels of fungi and higher levels of bacteria.Significantly higher abundances of the fungi Candida and Aspergillus in patients with reticular OLP and of Alternaria and Sclerotiniaceae_unidentified in patients with erosive OLP were observed compared to the healthy controls.Aspergillus was identified as an “OLP-associated” fungus because of its detection at a higher frequency than in the healthy controls.Second,the co-occurrence patterns of the salivary mycobiome–bacteriome demonstrated negative associations between specific fungal and bacterial taxa identified in the healthy controls,which diminished in the reticular OLP group and even became positive in the erosive OLP group.Moreover,the oral cavities of OLP patients were colonized by dysbiotic oral flora with lower ecological network complexity and decreased fungal–Firmicutes and increased fungal–Bacteroidetes sub-networks.Third,several keystone fungal genera (Bovista,Erysiphe,Psathyrella,etc.) demonstrated significant correlations with clinical scores and IL-17 levels.Thus,we established that fungal dysbiosis is associated with the aggravation of OLP.Fungal dysbiosis could alter the salivary bacteriome or may reflect a direct effect of host immunity,which participates in OLP pathogenesis. | Yan Li Kun Wang Bo Zhang Qichao Tu Yufei Yao Bomiao Cui Biao Ren Jinzhi He Xin Shen Joy D.Van Nostrand Jizhong Zhou Wenyuan Shi Liying Xiao Changqing Lu Xuedong Zhou | 2019 | International Journal of Oral Science2019,11,3: | 8 |
| 20 | Advanced Ni-Nx-C single-site catalysts for CO2 electroreduction to CO based on hierarchical carbon nanocages and S-doping显示文摘Metal-nitrogen-carbon materials are promising catalysts for CO2 electroreduction to CO. Herein, by taking the unique hierarchical carbon nanocages as the support, an advanced nickel-nitrogen-carbon single-site catalyst is conveniently prepared by pyrolyzing the mixture of NiCl2 and phenanthroline, which exhibits a Faradaic efficiency plateau of > 87% in a wide potential window of −0.6 – −1.0 V. Further S-doping by adding KSCN into the precursor much enhances the CO specific current density by 68%, up to 37.5 A·g−1 at −0.8 V, along with an improved CO Faradaic efficiency plateau of > 90%. Such an enhancement can be ascribed to the facilitated CO pathway and suppressed hydrogen evolution from thermodynamic viewpoint as well as the increased electroactive surface area and improved charge transfer fromkinetic viewpoint due to the S-doping. This study demonstrates a simple and effective approach to advanced electrocatalysts by synergetic modification of the porous carbon-based support and electronic structure of the active sites. | Yiqun Chen Yuejian Yao Yujian Xia Kun Mao Gongao Tang Qiang Wu Lijun Yang Xizhang Wang Xuhui Sun Zheng Hu | 2020 | Nano Research2020,13,10: | 8 |
