1A series of naphthalimide azoles: Design, synthesis and bioactive evaluation as potential antimicrobial agents显示文摘A series of naphthalimide azoles as potential antibacterial and antifungal agents were conveniently and efficiently synthesized starting from commercially available 6-bromobenzo[de]isochromene-1,3-dione. All the new compounds were characterized by NMR, IR, MS and HRMS spectra. Their antimicrobial activities were evaluated against four Gram-positive bacteria, four Gram-negative bacteria and two fungi using two-fold serial dilution technique. The biological assay indicated that most of the prepared compounds exhibited inhibition to the tested strains. In particular, the triazolium derivatives not only gave higher efficacy than their corresponding precursory azoles, but also demonstrated comparable or even better potency than the reference drugs Chloromycin, Orbifloxacin and Fluconazole. Some factors including structural fragments, pH and ClogP values of the target molecules were also preliminarily discussed.DAMU Guri L. V.

4The MNS16A polymorphism in the TERT gene in peri-centenarians from the Han Chinese population显示文摘MNS16A,a variable number of tandem repeats polymorphism in the TERT gene,has been suggested to regulate telomerase activity.As telomerase activity has been reported to be related to life-span,we hypothesized that this polymorphism might affect human longevity by controlling the length of the telomere.To test this hypothesis,we collected 446 unrelated pericentenarian individuals(age≥90,mean 94.45±3.45 years)and 332 normal controls(age 22-53,mean 35.0±12.0 years)from Dujiangyan,Sichuan,China.We typed the MNS16A polymorphism in both groups,and compared the allele and genotype frequencies between the peri-centenarian and control groups using the chi-squared test.There was no significant difference between the peri-centenarian and control groups.Thus,the MNS16A polymorphism in TERT might not influence human life-span,at least in the Han Chinese population studied here.LIU LiNa WANG ChengYe LU Xiang XIAO FuHui WANG HuaWei YANG LiQin XU LiangYou KONG QingPeng 2014Science China(Life Sciences)2014,57,10:1

7The advantages of penehyclidine hydrochloride over atropine in acute organophosphorus pesticide poisoning:A meta-analysis显示文摘Background:Penehyclidine hydrochloride(PHC)has been used for many years as an anticholinergic drug for the treatment of acute organophosphorus pesticide poisoning(AOPP).The purpose of this meta-analysis was to explore whether PHC has advantages over atropine in the use of anticholinergic drugs in AOPP.Methods:We searched Scopus,Embase,Cochrane,PubMed,ProQuest,Ovid,Web of Science,China Science and Technology Journal Database(VIP),Duxiu,Chinese Biomedical literature(CBM),WanFang,and Chinese National Knowledge Infrastructure(CNKI),from inception to March 2022.After all qualified randomized controlled trials(RCTs)were included,we conducted quality evaluation,data extraction,and statistical analysis.Statistics using risk ratios(RR),weighted mean difference(WMD),and standard mean difference(SMD).Results:Our meta-analysis included 20,797 subjects from 240 studies across 242 different hospitals in China.Compared with the atropine group,the PHC group showed decreased mortality rate(RR=0.20,95%confidence intervals[CI]:0.16–0.25,P<0.001),hospitalization time(WMD=-3.89,95%CI:-4.37 to-3.41,P<0.001),overall incidence rate of complications(RR=0.35,95%CI:0.28–0.43,P<0.001),overall incidence of adverse reactions(RR=0.19,95%CI:0.17–0.22,P<0.001),total symptom disappearance time(SMD=-2.13,95%CI:-2.35 to-1.90,P<0.001),time for cholinesterase activity to return to normal value 50–60%(SMD=-1.87,95%CI:-2.03 to-1.70,P<0.001),coma time(WMD=-5.57,95%CI:-7.20 to-3.95,P<0.001),and mechanical ventilation time(WMD=-2.16,95%CI:-2.79 to-1.53,P<0.001).Conclusion:PHC has several advantages over atropine as an anticholinergic drug in AOPP.Siyao Zeng Lei Ma Lishan Yang Xiaodong Hu Cheng Wang Xinxin Guo Yi Li Yi Gou Yao Zhang Shengming Li Shaotong Zhang Xiaoxuan Wu Meihong Li Jing Lei Bingqian Li Chengfei Bi Like Ma Qingpeng Luo 2023Journal of Intensive Medicine2023,3,2:0
8Adaptively temporal graph convolution model for epidemic prediction of multiple age groups显示文摘Introduction:Multivariate time series prediction of infectious diseases is significant to public health,and the deep learning method has attracted increasing attention in this research field.Material and methods:An adaptively temporal graph convolution(ATGCN)model,which leams the contact patterns of multiple age groups in a graph-based approach,was proposed for COVID-19 and influenza prediction.We compared ATGCN with autoregressive models,deep sequence learning models,and experience-based ATGCN models in short-term and long-term prediction tasks.Results:Results showed that the ATGCN model performed better than the autoregressive models and the deep sequence learning models on two datasets in both short-term(12.5%and 10%improvements on RMSE)and longterm(12.4%and 5%improvements on RMSE)prediction tasks.And the RMSE of ATGCN predictions fluctuated least in different age groups of COVID-19(0.029±0.003)and influenza(0.059±0.008).Compared with the Ones-ATGCN model or the Pre-ATGCN model,the ATGCN model was more robust in performance,with RMSE of 0.0293 and 0.06 on two datasets when horizon is one.Discussion:Our research indicates a broad application prospect of deep learning in the field of infectious disease prediction.Transmission characteristics and domain knowledge of infectious diseases should be further applied to the design of deep learning models and feature selection.Conclusion:The ATGCN model addressed the multivariate time series forecasting in a graph-based deep learning approach and achieved robust prediction on the confirmed cases of multiple age groups,indicating its great potentials for exploring the implicit interactions of multivariate variables.Yuejiao Wang Dajun Daniel Zeng Qingpeng Zhang Pengfei Zhao Xiaoli Wang Quanyi Wang Yin Luo Zhidong Cao 2022Fundamental Research2022,2,2:0
9Electro-chemo-mechanical design of polymer matrix in composited LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2) cathode endows solid-state batteries with superior performance显示文摘Nickel-rich LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)(NCM811) cathode material has been widely concerned due to its high voltage,high specific capacity and excellent rate performance,which is considered as one of the most promising cathode materials for the next generation of high-energy-density solid-state lithium batteries.However,serious electro-chemo-mechanical degradation of Nickel-rich cathode during cycling,especially at a high voltage(over 4.5 V),constrains their large-scale application.Here,using the multiphysical simulation,highly-conductive polymer matrix with spontaneous stress-buffering effect was uncovered theoretically for reinforcing the electrochemical performance of composited NCM81 1 cathode through the visualization of uniform concentration distribution of Li-ion coupled with improved stress field inside NCM811 cathode.Thereupon,polyacrylonitrile(PAN) and soft polyvinylidene fluoride(PVDF) were selected as the polymer matrix to fabricate the composited NCM811 cathode(PVDFPAN@NCM811) for improving the electrochemical performance of the solid-state NMC811|Li full cells,which can maintain high capacity over 146.2 mA h g^(-1)after 200 cycles at a high voltage of 4.5 V.Suggestively,designing a multifunctional polymer matrix with high ionic conductivity and mechanical property can buffer the stress and maintain the integrity of the structure,which can be regarded as the door-opening avenue to realize the high electrochemical performance of Ni-rich cathode for solidstate batteries.Haolong Jiang Xieyu Xu Qingpeng Guo Hui Wang Jiayi Zheng Yuhao Zhu Huize Jiang Olesya O.Kapitanova Valentyn S.Volkov Jialin Wang Yaqi Chen Yongjing Wang Yu Han Chunman Zheng Kai Xie Shizhao Xiong Yangyang Liu Xingxing Jiao 2023Journal of Energy Chemistry2023,,3:0
10Reinforced interface endows the lithium anode with stable cycle at high-temperature of 80℃显示文摘Embracing ultrahigh theoretical capacity of 3860 mA h g^(-1)and the lowest reduction potential of-3.04 V(versus standard hydrogen electrode),lithium(Li) is considered as the 'holy grail' material for pursuing higher energy density,of which application has been challenged due to the unstable interface caused by the non-uniform electrodeposition as well as high chemical activity.Operating at higher temperature can be recommended to uniform electrodeposition of Li metal.Nevertheless,the intrinsic side-reaction between Li metal anode and electrolyte is inevitably aggravated and thus fosters the failure of Li metal anode rapidly with uneven electrodeposition.Here,a kind of temperature-tolerated ionic liquid(1-methyl-3-ethylimidazole bis(fluorosulfo nyl)imide/lithium bis(trifluoromethylsulfo nyl)imide,EF/LT)based electrolyte that matrixed with poly(vinylidene fluoride-hexafluoropropylene) was designed to maintain the interfacial stabilization of Li metal due to the weak interfacial reaction and uniform electrodeposition at high temperature of 80℃.It is the matter that the 660-h cycle with lower polarization is achieved with EF/LT-based electrolyte at temperature of 80 ℃ and the full cell embraces outstanding cyclic performance,without capacity fading within 100 cycles.Delighting,a door for practical application of Li metal anode for higher energy density as the carbon neutrality progresses in the blooming human society has been opened gradually.Yuhao Zhu Xieyu Xu Qingpeng Guo Yu Han Haolong Jiang Huize Jiang Hui Wang Pavel V.Evdokimov Olesya O.Kapitanova Valentyn S.Volkov Yongjing Wang Shizhao Xiong Chunman Zheng Kai Xie Xingxing Jiao Yangyang Liu 2023Journal of Energy Chemistry2023,,3:0
11Allocation patterns of nonstructural carbohydrates in response to CO_(2)elevation and nitrogen deposition in Cunninghamia lanceolata saplings显示文摘Stored nonstructural carbohydrates(NSC)indicate a balance between photosynthetic carbon(C)assimilation and growth investment or loss through respiration and root exudation.They play an important role in plant function and whole-plant level C cycling.CO_(2)elevation and nitrogen(N)deposition,which are two major environmental issues worldwide,aff ect plant photosynthetic C assimilation and C release in forest ecosystems.However,information regarding the eff ect of CO_(2)elevation and N deposition on NSC storage in diff erent organs remains limited,especially regarding the trade-off between growth and NSC reserves.Therefore,here we analyzed the variations in the NSC storage in diff erent organs of Chinese fi r(Cunninghamia lanceolata)under CO_(2)elevation and N addition and found that NSC concentrations and contents in all organs of Chinese fi r saplings increased remarkably under CO_(2)elevation.However,N addition induced diff erential accumulation of NSC among various organs.Specifi cally,N addition decreased the NSC concentrations of needles,branches,stems,and fi ne roots,but increased the NSC contents of branches and coarse roots.The increase in the NSC contents of roots was more pronounced than that in the NSC content of aboveground organs under CO_(2)elevation.The role of N addition in the increase in the structural biomass of aboveground organs was greater than that in the increase in the structural biomass of roots.This result indicated that a diff erent tradeoff between growth and NSC storage occurred to alleviate resource limitations under CO_(2)elevation and N addition and highlights the importance of separating biomass into structural biomass and NSC reserves when investigating the eff ects of environmental change on biomass allocation.Wenhui Zheng Renshan Li Qingpeng Yang Weidong Zhang Ke Huang Xin Guan Longchi Chen Xin Yu Qingkui Wang Silong Wang 2023Journal of Forestry Research2023,34,1:0
12Molecular Cloning and Expression Analysis of zm NAC Transcription Factor Gene显示文摘In order to study NAC transcription factor gene in maize(Zea mays), a completed c NAC encoding the NAC-like gene homologue named as Zm NAC was cloned from the maize inbred line Zheng 58 using a pair of specific primers, which were designed to cover the full coding region according to the reported NAC gene family. The length of the sequences was 953 bp.The deduced amino acid sequences analysis showed that the sequence contained the complete coding region of a typical NAC gene, including a complete open reading frame which was 939 bp. The study analyzed the expression patterns of NAC transcript gene induced in various PEG(polyethylene glycol) simulated drought condition. Real-time PCR indicated that maize NAC gene can be induced in various PEG to abiotic stress responses, it could express constitutively to adopt the drought condition in short time, and the higher drought, the more early expression, which indicated that NAC transcript gene could be involved in the regulation of the defense response.Rong ZHOU Yanwei WANG Jinbao PAN Qingpeng SUN Yihong JI Min LU Jun HAN Zhangjie NAN Yongkun YU 2016Agricultural Science & Technology2016,17,2:0
13Stereoselective synthesis of the 3,6-branched Fuziα-glucans up to 15-mer via a one-pot and convergent glycosylation strategy显示文摘A family of the 3,6-branched Fuziα-glucans including the pentasaccharide repeating unit as well as its di-and trimers were efficiently achieved via a one-pot and convergent glycosylation strategy.All the protectedα-glucans up to 15-mer were assembled with high yields and excellentα-stereoselectivity,which was secured by the synergisticα-directing effects of the Tol SCl/Ag OTf promotion system and the stericβ-facial shielding of bulky saccharide residues linked at the 6-O-position of glucosyl donors.Moreover,the 3,6-branched architecture of glycosyl donor was revealed to be more favorable for theα-selective glucosidation of primary hydroxyl group,especially in the case of large oligosaccharide acceptor.The structurally well-defined syntheticα-glucans would be useful for various biological studies.Qingpeng Zhao Shihao Zhou Yue Wang Xiaoyu Yang Youhui Meng Yanxin Zhang Jian Gao 2023Chinese Chemical Letters2023,34,6:0
14Short-Term Visual Experience Leads to Potentiation of Spontaneous Activity in Mouse Superior Colliculus显示文摘Spontaneous activity in the brain maintains an internal structured pattern that reflects the external environment,which is essential for processing information and developing perception and cognition.An essential prerequisite of spontaneous activity for perception is the ability to reverberate external information,such as by potentiation.Yet its role in the processing of potentiation in mouse superior colliculus(SC)neurons is less studied.Here,we used electrophysiological recording,optogenetics,and drug infusion methods to investigate the mechanism of potentiation in SC neurons.We found that visual experience potentiated SC neurons several minutes later in different developmental stages,and the similarity between spontaneous and visually-evoked activity increased with age.Before eye-opening,activation of retinal ganglion cells that expressed ChR2 also induced the potentiation of spontaneous activity in the mouse SC.Potentiation was dependenton stimulus number and showed feature selectivity for direction and orientation.Optogenetic activation of parvalbumin neurons in the SC attenuated the potentiation induced by visual experience.Furthermore,potentiation in SC neurons was blocked by inhibiting the glutamate transporter GLT1.These results indicated that the potentiation induced by a visual stimulus might play a key role in shaping the internal representation of the environment,and serves as a carrier for short-term memory consolidation.Qingpeng Yu Hang Fu Gang Wang Jiayi Zhang Biao Yan 2021Neuroscience Bulletin2021,37,3:0
