3A readily monitored and controllable hydrothermal system for the facile,cost-effective transformation of FGD gypsum to calcium sulfate hemihydrate whiskers显示文摘The controllable transformation of flue gas desulfurization(FGD)gypsum to calcium sulfate hemihydrate(HH)whiskers under facile,readily monitored,and cost-effective hydrothermal conditions could play a vital role in the preparation of high quality HH whiskers and improve our understanding of the transformation process.This work assessed the conversion of FGD gypsum to HH whiskers in 5×10^(-4)mol/L H_(2)SO_(4)and 1.5 wt%CuCl_(2)at 120℃while determining the effects of temperature as well as H_(2)SO_(4)and CuCl_(2)concentrations on transformation kinetics.The preparation of HH whiskers was found to involve a solution-mediated transformation from the dihydrate(DH)to theα-HH.This transition was determined to proceed via a dissolution crystallization mechanism,the rate of which was controlled by nucleation and growth of the HH whiskers.An autocatalytic kinetic model was established based on variations in the HH whiskers mole fraction over time,and this model accurately fit the experimental data with R2=0.990.Increasing the temperature or H_(2)SO_(4)concentration accelerated the transformation by modifying the super-saturation and water activity in the reaction solution,while increasing the CuCl_(2)concentration had the opposite effect.The hydrothermal conditions had an important effect on the transformation from FGD gypsum to HH whiskers.Bolun Cao Xiao Wang Xiaoting Zhang Biao Jin Zhuoyue Xu Xueping Liu Wei Zhang Liushuan Yang 2021Particuology2021,19,1:8
4Unique characteristics of the genetics epidemiology of amyotrophic lateral sclerosis in China显示文摘Continual discoveries of new genes and unraveling the genetic etiology in amyotrophic lateral sclerosis(ALS) have provided greater insight into the underlying pathogenesis in motor neuron degeneration, as well as facilitating the disease modeling and the testing of targeted therapeutics. While, the genetic etiology accounted for two-thirds of FALS and approximately 11% of SALS in Caucasians. However, the contributions of these causative genes to ALS vary among different populations. Furthermore, the prominent difference between Chinese population and other ethnics remains a source of ongoing debate. We systemically reviewed genetics literature of Chinese ALS populations and updated the mutation frequencies of the main ALS-implicated genes aiming to determine the genetic features of ALS in Chinese population. We also reviewed the associations between ALSimplicated single nucleotide polymorphisms(SNPs) and the risk of ALS in Chinese population. A total of 116 studies were included in this analysis(86 gene mutation study articles and 30 SNPs study articles). The results showed that the overall gene mutation rates of ALS-related causative genes were 55.0% in familial ALS(FALS) and 11.7% in sporadic ALS(SALS) in Chinese population. In Chinese FALS, the highest mutation frequency was found in SOD1 gene(25.6%), followed by FUS(5.8%), TARDBP(5.8%), DCTN1(3.6%) and C9 orf 72(3.5%). In Chinese SALS, the highest mutation frequency was also identified in SOD1 gene(1.6%), followed by ANXA11(1.4%), FUS(1.3%), SQSTM1(1.0%), OPTN(0.9%) and CCNF(0.8%).The associations between several SNPs and risk of ALS were also reported in Chinese population. The genetic features of ALS in Chinese population are significantly different from those in Caucasian population, indicating an association between genetic susceptibility and origin of population. Further explorations are required to understand the gene complexity of ALS, including the contribution of most minor genes and the molecular mechanisms in ALS pathologies.Qianqian Wei Xueping Chen Yongping Chen Ruwei Ou Bei Cao Yanbing Hou Lingyu Zhang Hui-Fang Shang 2019Science China(Life Sciences)2019,62,4:7
5A Middle-Upper Devonian Boundary Section in the Open Platform,Platform Margin Facies of Guilin,South China显示文摘The Caiziyan Middle and Upper Devonian boundary section is located approximately 30 km northeast of Guilin.It hosts relatively abundant benthic and common-rare pelagic fossils,including brachiopods,corals,tentaculites,and conodonts,which may serve as a better suitable section for pelagic and neritic stratigraphic correlation.In this section,10'standard'conodont zones are recognized across the Givetian-Frasnian boundary,including,in descending order,the Lower hassi Zone,punctata Zone,transitans Zone,the Upper falsiovalis Zone,the Lower falsiovalis Zone,disparilis Zone,the Upper hermanni-cristatus Zone,the Lower hermanni-cristatus Zone,the Upper varcus Zone, and the Middle varcus Zone,all of which are defined by the first occurrence of their defining conodont species.The Middle-Upper Devonian(Givetian-Frasnian) boundary is defined by the first occurrence of Ancyrodella pristina in accordance with the Global Stratotype Section and Point(GSSP),which is assigned at 6.2m above the base of bed 19 in the Caiziyan section.LI Hua MA Xueping WEI Longming 2009Acta Geologica Sinica(English Edition)2009,83,3:7
6Nucleic acids and analogs for bone regeneration显示文摘With the incidence of different bone diseases increasing, effective therapies are needed that coordinate a combination of various technologies and biological materials. Bone tissue engineering has also been considered as a promising strategy to repair various bone defects. Therefore, different biological materials that can promote stem cell proliferation, migration, and osteoblastic differentiation to accelerate bone tissue regeneration and repair have also become the focus of research in multiple fields. Stem cell therapy, biomaterial scaffolds, and biological growth factors have shown potential for bone tissue engineering; however, off-target effects and cytotoxicity have limited their clinical use. The application of nucleic acids(deoxyribonucleic acid or ribonucleic acid)and nucleic acid analogs(peptide nucleic acids or locked nucleic acids), which are designed based on foreign genes or with special structures, can be taken up by target cells to exert different effects such as modulating protein expression, replacing a missing gene, or targeting specific gens or proteins. Due to some drawbacks, nucleic acids and nucleic acid analogs are combined with various delivery systems to exert enhanced effects, but current studies of these molecules have not yet satisfied clinical requirements. In-depth studies of nucleic acid or nucleic acid analog delivery systems have been performed, with a particular focus on bone tissue regeneration and repair. In this review, we mainly introduce delivery systems for nucleic acids and nucleic acid analogs and their applications in bone repair and regeneration. At the same time, the application of conventional scaffold materials for the delivery of nucleic acids and nucleic acid analogs is also discussed.Yuxin Zhang Wenjuan Ma Yuxi Zhan Chenchen Mao Xiaoru Shao Xueping Xie Xiawei Wei Yunfeng Lin 2018Bone Research2018,6,4:3
7Distribution of soil aggregates and organic carbon in deep soil under long-term conservation tillage with residual retention in dryland显示文摘To ascertain the effects of long-term conservation tillage and residue retention on soil organic carbon(SOC) content and aggregate distribution in a deep soil(>20-cm depth) in a dryland environment,this paper analyzed the SOC and aggregate distribution in soil, and the aggregate-associated organic carbon(OC) and SOC physical fractions. Conservation tillage(reduced tillage with residue incorporated(RT) and no-tillage with residue mulch(NT)) significantly increased SOC sequestration and soil aggregation in deep soil compared with conventional tillage with residue removal(CT). Compared with CT, RT significantly increased the proportion of small macroaggregates by 23%–81% in the 10–80 cm layer, and the OC content in small macroaggregates by 1%–58% in the 0–80 cm layer. RT significantly increased(by 24%–90%) the OC content in mineral-SOC within small macroaggregates in the 0–60 cm layer, while there was a 23%–80% increase in the 0–40 cm layer with NT. These results indicated that:(1) conservation tillage treatments are beneficial for soil aggregation and SOC sequestration in a deep soil in a dryland environment; and(2)the SOC in mineral-associated OC plays important roles in soil aggregation and SOC sequestration. In conclusion, RT with NT is recommended as an agricultural management tool in dryland soils because of its role in improving soil aggregation and SOC sequestration.WANG Bisheng GAO Lili YU Weishui WEI Xueqin LI Jing LI Shengping SONG Xiaojun LIANG Guopeng CAI Dianxiong WU Xueping 2019Journal of Arid Land2019,11,2:3
8Time-delayed feedback control optimization for quasi linear systems under random excitations显示文摘A strategy for time-delayed feedback controloptimization of quasi linear systems with random excitationis proposed. First, the stochastic averaging method isused to reduce the dimension of the state space and to derivethe stationary response of the system. Secondly, the controllaw is assumed to be velocity feedback control with timedelay and the unknown control gains are determined by theperformance indices. The response of the controlled systemis predicted through solving the Fokker-Plank-Kolmogorovequation associated with the averaged It equation. Finally,numerical examples are used to illustrate the proposed controlmethod, and the numerical results are confirmed byMonte Carlo simulation.Xueping Li Demin Wei Weiqiu Zhu School of Civil Engineering and Transportation, South China University of Technology, 510640 Guangzhou, China Department of Mechanics, State Key Laboratory of Fluid Power Transmission and Control, Zhejiang University, 310027 Hangzhou, China 2009Acta Mechanica Sinica2009,25,3:2
9Preparation of Wear Resistant Materials by Melting and Diffusion Process显示文摘A wear-resistant material reinforced with VCp was manufactured by the in-mold melting process, in which the high-vanadium alloy-rods were melted by high temperature liquid steel and elements diffused into the liquid. Microstructure of the material was examined by OM, SEM, and XRD, and alloy elements in the diffusion layer were studied by EDS, and the hardness of the material was tested by HRS. The experimental results show that the material gradually changes hardness, which is due to the uniformly existents of carbide particles on martensite matrix and the gradient distribution of vanadium and carbide.余世浩 WEI Xueping ZENG Hui 2012Journal of Wuhan University of Technology(Materials Science)2012,27,6:1

16Intercellular transfer of activated STING triggered by RAB22A-mediated non-canonical autophagy promotes antitumor immunity显示文摘STING,an endoplasmic reticulum(ER)transmembrane protein,mediates innate immune activation upon cGAMP stimulation and is degraded through autophagy.Here,we report that activated STING could be transferred between cells to promote antitumor immunity,a process triggered by RAB22A-mediated non-canonical autophagy.Mechanistically,RAB22A engages PI4K2A to generate PI4P that recruits the Atg12–Atg5–Atg16L1 complex,inducing the formation of ER-derived RAB22A-mediated non-canonical autophagosome,in which STING activated by agonists or chemoradiotherapy is packaged.This RAB22A-induced autophagosome fuses with RAB22A-positive early endosome,generating a new organelle that we name Rafeesome(RAB22A-mediated non-canonical autophagosome fused with early endosome).Meanwhile,RAB22A inactivates RAB7 to suppress the fusion of Rafeesome with lysosome,thereby enabling the secretion of the inner vesicle of the autophagosome bearing activated STING as a new type of extracellular vesicle that we define as R-EV(RAB22A-induced extracellular vesicle).Activated STING-containing R-EVs induce IFNβrelease from recipient cells to the tumor microenvironment,promoting antitumor immunity.Consistently,RAB22A enhances the antitumor effect of the STING agonist diABZI in mice,and a high RAB22A level predicts good survival in nasopharyngeal cancer patients treated with chemoradiotherapy.Our findings reveal that Rafeesome regulates the intercellular transfer of activated STING to trigger and spread antitumor immunity,and that the inner vesicle of non-canonical autophagosome originated from ER is secreted as R-EV,providing a new perspective for understanding the intercellular communication of organelle membrane proteins.Ying Gao Xueping Zheng Boyang Chang Yujie Lin Xiaodan Huang Wen Wang Shirong Ding Weixiang Zhan Shang Wang Beibei Xiao Lanqing Huo Youhui Yu Yilin Chen Run Gong Yuanzhong Wu Ruhua Zhang Li Zhong Xin Wang Qiuyan Chen Song Gao Zhengfan Jiang Denghui Wei Tiebang Kang 2022Cell Research2022,32,12:1

18Construction of a high-density mutant population of Chinese cabbage facilitates the genetic dissection of agronomic traits显示文摘Chinese cabbage(Brassica rapa ssp.pekinensis)is an economically important vegetable crop throughout the world,especially in Asia.High-quality genome sequences are available for Chinese cabbage,but gene functional studies remain challenging.To promote functional genomic studies of Chinese cabbage,we generated an ethyl methane sulfonate(EMS)mutant population of~8000 M_(2) plants using the double haploid inbred line A03 as the parent.The genome of A03 was sequenced and used as a reference for high-throughput functional characterization of gene mutations at the whole-genome level.A total of 300 M_(2) to M_(5) EMS mutants were phenotypically screened and then sequenced,revealing 750629 SNPs and 46272 InDel mutations that cover 98.27%of all predicted genes in the A03 genome.A forward-genetics approach was successfully used to identify two genes with chloroplast-related functions that are responsible for the yellow leaf mutant trait.A reverse-genetics approach was also used to identify associations between mutations in five genes of the glucosinolate biosynthetic pathway and variations in glucosinolate content of the mutant plants.In addition,we built the Chinese cabbage EMS mutation database(CCEMD,www.bioinformaticslab.cn/EMSmutation/home)to increase the usability of this mutant population resource.In summary,we performed large-scale screening of a heading Chinese cabbage EMS mutant collection at the phenotypic and genotypic levels,which will facilitate gene mining of Chinese cabbage and might also be useful for the study of other Brassica crops.Xiaoxue Sun Xing Li Yin Lu Shan Wang Xiaomeng Zhang Kang Zhang Xiangjie Su Mengyang Liu Daling Feng Shuangxia Luo Aixia Gu Yu Fu Xueping Chen Shuxin Xuan Yanhua Wang Donghui Xu Shumin Chen Wei Ma Shuxing Shen Feng Cheng Jianjun Zhao 2022Molecular Plant2022,15,5:1
19A Study on Remediation Technologies for Cadmium Contamination in Greenhouse Vegetable Fields显示文摘Based on the literature and experimental results, three kinds of amendments, namely, rice biochar, hydroxyapatite and potassium dihydrogen phosphate(KH2PO4), and deeper ploughing were selected to evaluate the field application effect of soil amendments and agronomic measures on the remediation of Cd contamination in greenhouses. Cd-contaminated greenhouse screening was conducted from 2015 to 2017. In September 2017, comparative tests of eight treatments were performed in September 2017, and a selective test was performed in September 2018. The results of the screening of contaminated areas indicated that the distributions of over-standard sites and Cd content were significantly different. Greenhouse No. 4, in which the highest over-standard rate was 83.33% and the average content of Cd in soil was 0.535 mg/kg, was used as a comparative test experimental site for eight treatments. Greenhouse No. 1 was selected as the optimum test greenhouse for selective testing, with three plots having average Cd concentrations of 0.530, 0.568 and 0.792 mg/kg. The 8 months following comparative treatment showed that the content of available Cd following the treatment of rice biochar+hydroxyapatite+deeper ploughing(treatment T6) was reduced by 32.55% and 24.96% compared with the CK(the control) and 2 months following treatment, respectively. The content of available Cd using rice biochar+KH2PO4+deeper ploughing(treatment T7) treatment decreased by 47.88% and 31.00% compared with the CK and 2 months following treatment. The selective test results showed that in rice biochar+hydroxyapatite+deeper ploughing: the total Cd content of decreased from 0.489 to 0.372 mg/kg(23.86% lower), compared with the CK, and the mean content of available Cd decreased by 10.71% after 8 months, which was the lowest available Cd measured(0.133 mg/kg). In addition, the bean plant Cd content, bioconcentration factor(BCF) and translocation coefficient(TF) decreased by 15.86%, 23.68% and 25.77%, respectively. Rice biochar+hydroxyapatite+deeper ploughing is a favoured technology for the remediation of Cd-contaminated protected vegetable fields.Xueping SHI Huiwei ZHAO Yiming LIU Wei LIU Chenghai ZHENG Chuan LU Lifang ZHAI 2021Agricultural Biotechnology2021,10,1:0
20Extruded monolith MnO_(x)-CeO_(2)-TiO_(2) catalyst for NH_(3)-SCR of low temperature flue gas from an industry boiler:Deactivation and recovery显示文摘The selective catalytic reduction(SCR) of NO_(x) with NH_(3)(NH_(3)-SCR) technology has been widely applied for reducing NO_(x) emissions from stationary and mobile sources.In this work,the extruded monolith MnO_(x)-CeO_(2)-TiO_(2) catalyst was installed in a cement kiln for NH_(3)-SCR of NO_(x),where the flue gas temperature was 110-140℃.It is found that the monolith catalyst is severely deactivated after operating for about 200 h with almost no NO_(x) conversion at 160℃ under GHSV of 50000 h^(-1),while the fresh monolith catalyst remains 60% NO_(x) conversion.Scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS),X-ray photoelectron spectroscopy(XPS),temperature-programmed desorption of SO_(2)(SO_(2)-TPD) and thermogravimetric-differential thermal analysis(TG-DTG) experiments reveal that both MnO_(x) and CeO_(2) oxides in monolith are severely sulfated to manganese sulfate and cerium sulfate,and the external monolith walls are covered by massive ceria sulfate and little ammonium nitrate.In situ diffuse reflectance infrared Fourier trans form spectroscopy(DRIFTS) analysis demonstrates that the formation of nitrates at low temperatures is inhibited due to the occupation of active sites in MnO_(x)-CeO_(2)-TiO_(2) by sulfates,resulting in the decrease of low temperature activity.After washing with water,the activity of deactivated monolith catalyst can be partially recovered,together with significant loss of manganese and cerium from monolith.Wei Shi Jingjing Liu Ying Zhu Lin Zhao Yonggang Wang Zhaohuan Cheng Xueping Peng Xiaoyan Shi Yunbo Yu Hong He 2023Journal of Rare Earths2023,41,9:0
