| 1 | Neuroprotective effect of Notch pathway inhibitor DAPT against focal cerebral ischemia/reperfusion 3 hours before model establishment显示文摘As an inhibitor of the Notch signaling pathway, N-[N-(3,5-difluorohenacetyl)-l-alanyl]-S-phenylglycine tert-butyl ester(DAPT) may protect brain tissue from serious ischemic injury. This study aimed to explore neuroprotection by DAPT after cerebral ischemia/reperfusion(I/R) injury. DAPT was intraperitoneally injected 3 hours before the establishment of a focal cerebral I/R model in the right middle cerebral artery of obstructed mice. Longa scores were used to assess neurological changes of mice. Nissl staining and TdT-mediated dUTP-biotin nick-end labeling staining were used to examine neuronal damage and cell apoptosis in the right prefrontal cortex, while immunofluorescence staining was used to detect glial fibrillary acidic protein-and Notch1-positive cells. Protein expression levels of Hes1 and Hes5 were detected by western blot assay in the right prefrontal cortex. Our results demonstrated that DAPT significantly improved neurobehavioral scores and relieved neuronal morphological damage. DAPT decreased the number of glial fibrillary acidic protein-and Notch1-positive cells in the right prefrontal cortex, while also reducing the number of apoptotic cells and decreasing interleukin-6 and tumor necrosis factor-α contents, and simultaneously downregulating Hes1 and Hes5 protein expression. These findings verify that DAPT alleviates pathological lesions and strengthens the anti-inflammatory response after cerebral I/R injury. Thus, DAPT might be developed as an effective drug for the prevention of cerebral I/R injury. | Jun-Jie Wang Jun-De Zhu Xian-Hu Zhang Ting-Ting Long Guo Ge Yan Yu | 2019 | Neural Regeneration Research2019，14，3： | 17 |

| 3 | Remediation of Steel Slag on Acidic Soil Contaminated by Heavy Metal显示文摘The technology of in situ immobilization with amendments is an important measure that remediates the soil contaminated by heavy metals, and selecting economical and effective amendments is the key. The effects and mechanism of steel slag, the silicon-rich alkaline byproduct which can remediate acidic soil contaminated by heavy metal, are mainly introduced in this paper to provide theory reference for future research. Firstly, the paper analyzes current research situation of in situ immobilization with amendments. Then, it introduces the main physicochemical properties of steel slag, and the effect on soil pH value as well as heavy metal activity. Besides, the paper elaborates the promoting effect on silicon-requiring plant and the strengthening mechanism for its resistant capability of heavy metal. According to the analysis, the application of steel slag could be a potential valuable strategy to remediate acidic soil contaminated by heavy metal by modifying the transformation of heavy metals in both soil and plant, so that the translocation of heavy metal in food chain is reduced. | Haihong GU Fuping LI Xiang GUAN Zhongwei LI Qiang YU | 2013 | Asian Agricultural Research2013，5，5： | 6 |
| 4 | Neural stem cell transplantation inhibits glial cell proliferation and P2X receptor-mediated neuropathic pain in spinal cord injury rats显示文摘P2X4 and P2X7 receptors play an important role in neuropathic pain after spinal cord injury. Regulation of P2X4 and P2X7 receptors can obviously reduce pain hypersensitivity after injury. To investigate the role of neural stem cell transplantation on P2X receptor-mediated neuropathic pain and explore related mechanisms, a rat model of spinal cord injury was prepared using the free-falling heavy body method with spinal cord segment 10 as the center. Neural stem cells were injected into the injured spinal cord segment using a micro-syringe. Expression levels of P2X4 and P2X7 receptors, neurofilament protein, and glial fibrillary acidic protein were determined by immunohistochemistry and western blot assay. In addition, sensory function was quantitatively assessed by current perception threshold. The Basso-Beattie-Bresnahan locomotor rating scale was used to assess neuropathological pain. The results showed that 4 weeks after neural stem cell transplantation, expression of neurofilament protein in the injured segment was markedly increased, while expression of glial fibrillary acidic protein and P2X4 and P2X7 receptors was decreased. At this time point, motor and sensory functions of rats were obviously improved, and neuropathic pain was alleviated. These findings demonstrated that neural stem cell transplantation reduced overexpression of P2X4 and P2X7 receptors, activated locomotor and sensory function reconstruction, and played an important role in neuropathic pain regulation after spinal cord injury. Therefore, neural stem cell transplantation is one potential option for relieving neuropathic pain mediated by P2X receptors. | Xiao-Jing Du Yue-Xia Chen Zun-Cheng Zheng Nan Wang Xiao-Yu Wang Fan-E Kong | 2019 | Neural Regeneration Research2019，14，5： | 6 |
| 5 | Secreted protein acidic and rich in cysteine(SPARC)induces epithelial-mesenchymal transition,enhancing migration and invasion,and is associated with high Gleason score in prostate cancer显示文摘Secreted protein acidic and rich in cysteine(SPARC)is a matricellular protein highly expressed in bone tissue that acts as achemoattractant factor promoting the arrival of prostate cancer(PCa)cells to the bone marrow.However,the contribution of SPARCduring the early stages of tumor progression remains unclear.In this study,we show that SPARC is highly expressed in PCa tissueswith a higher Gleason score.Through stable knockdown and overexpression of SPARC in PC3 and LNCaP cells,respectively,here wedem on strate that en doge nous SPARC induces the epithelial-mesenchymal tran sition(EMT),decreasing E-cadheri n and cytokeratin18 and increasing N-cadheri n and vime ntin.Moreover,SPARC in duces the expression of EMT regulatory tran scription factors Snailfamily transcriptional repressor 1(Snail),Snail family transcriptional repressor 2(Slug),and zinc finger E-box binding homeobox 1(Zeb1).In addition,SPARC knockdown in PC3 cells decreases migration and invasion in vitro,without modifying cell proliferation.Our results indicate that SPARC might facilitate tumor progression by modifying the cellular phenotype in cancer cells. | Fernanda Lopez-Moncada Maria Jose Torres Enrique A Castellon Hector R Contreras | 2019 | Asian Journal of Andrology2019，21，6： | 5 |
| 6 | SMFs-supported Pd nanocatalysts in selective acetylene hydrogenation:Pore structure-dependent deactivation mechanism显示文摘In the present study,CNFs,ZnO and Al2O3 were deposited on the SMFs panels to investigate the deactivation mechanism of Pd-based catalysts in selective acetylene hydrogenation reaction.The examined supports were characterized by SEM,NH3-TPD and N2adsorption-desorption isotherms to indicate their intrinsic characteristics.Furthermore,in order to understand the mechanism of deactivation,the resulted green oil was characterized using FTIR and SIM DIS.FTIR results confirmed the presence of more unsaturated constituents and then,more branched hydrocarbons formed upon the reaction over alumina-supported catalyst in comparison with the ones supported on CNFs and ZnO,which in turn,could block the pores mouths.Besides the limited hydrogen transfer,N2 adsorption-desorption isotherms results supported that the lowest pore diameters of Al2O3/SMFs close to the surface led to fast deactivation,compared with the other catalysts,especially at higher temperatures. | Elaheh Esmaeili Ali Morad Rashidi Yadollah Mortazavi Abbas Ali Khodadadi Mehdi Rashidzadeh | 2013 | Journal of Energy Chemistry2013，22，5： | 5 |
| 7 | Study on Isolation and Raman Spectroscopy of Glycinin in Soybean Protein显示文摘The secondary structures of soybean glycinin was investigated by Raman spectroscopy and its acidic and basic polypeptides were isolated. The results showed that the secondary structures of glycinin were mainly composed of 21.51% α-helix, 41.62% β-sheet,24.70% β-turn, and 12.18% random coil. For the disulfide bridge(—S—S—), the ratios were 34.8% gauche—gauche—gauche(g—g—g), 32.1% gauche—gauche—trans(g—g—t), and 33.1% trans-gauche-trans(t—g—t). The I_(850)/I_(830) intensity ratio of glycinin Raman tyrosine doublet confirmed that the contents of the N-buried and N-exposed tyrosine residue were 14.1% and 85.9%,respectively. The typical acidic subunit A and basic subunit B were clearly separated by heat denaturation and reduction withβ-mercaptoethanol, and their corresponding molecular masses were 42 and 38 ku, respectively. Raman spectroscopic analysis can be used to determine the secondary structural properties of glycinin. Further studies of the glycinin structures will be helpful for the utilization of soybean protein resources. | YIN Haicheng HUANG Jin ZHANG Huiru | 2018 | Grain & Oil Science and Technology2018，1，2： | 5 |
| 8 | Antidiabetic principles of Loranthus micranthus Linn.parasitic on Persea americana显示文摘Objective:To explore antidiabetic principles of the Eastern Nigeria mistletoe,Loranlhus micranthus Linn,parasitic on Persea Americana.Methods:The weakly acidic fraction of the aqueous methanol extract of the leaves of Loranlhus micranthus(Linn.) was isolated and tested for its antidiabetic activities.The isolation of the weakly acidic fraction was carried out following established physico-chemical based procedures.Furthermore,alloxan-induced diabetic rats were treated intraperitoneally(ip) with 250 mg/kg and 400 mg/kg of the weakly acidic fraction, glibenclamide 10 mg/kg(positive control) and 2 mg/kg of 3%v/v tween 20(negative control).The sugar levels of the treated and untreated animals were determined by withdrawing the blood at regular intervals and testing them with an automated glucometer.The phytochemical analysis of the acidic fraction was carried out using standard procedures.Chromatographic techniques were employed in the subsequent isolation and purification of the constituents of the weakly acidic fraction.Results:It was shown that the maximum effect of the weakly acidic fraction was obtained at 24 hours after administration and was found to be statistically comparable with that of the positive control.The phytochemical analysis revealed the presence of steroids,terpenoids, alkaloids,flavonoids,glycosides,carbohydrates,saponins,and acidic compounds in the crude extract and carbohydrates,flavonoids.terpenoids and oil in the weakly acidic fraction.Further purification of the weakly acidic fraction of the methanol extract using thin layer chromatography shows that toluene:methanol:diethyl amine(3:1:1) and chloroform:methanol:diethyl amine (9:1:1) are the best solvent system for the isolation of the various components of the weakly acidic fraction of the crude methanol extract of Loranlhus micranthus.Conclusions:The present study has led to the conclusion that the weakly acidic fraction of the plant under study has the potent antidiabetic activity and that the various components can be isolated using basic chromatographic techniques. | Patience Ogoamaka Osadebe Edwin Ogechukwu Omeje Sylvester Chukwuemeka Nworu Charles Okechukwu Esimone Philip Felix Uzor Ernest kenechukwu David John Uchechukwu Uzoma | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，8： | 4 |
| 9 | Construction and Analysis of Three-dimensional Graphic Model of Single-chain Fv Derived from an Anti-human Placental Acidic Isoferritin Monoclonal Antibody by Computer显示文摘Summary: A three-dimensional (3D) graphic model of a single-chain Fv (scFv) which was derived from an anti-human placental acidic isoferritin (PAF) monoclonal antibody (MAb) was construct- ed by a homologous protein-predicting computer algorithm on Silicon graphic computer station. The structure, surface static electricity and hydrophobicity of scFv were investigated. Computer graphic modelling indicated that all regions of scFv including the linker, variable regions of the heavy (VH) and light (VL) chains were suitable. The VH region and the VL region were involved in composing the 'hydrophobic pocket'. The linker was drifted away VH and VL regions. The complementarity determining regions (CDRs) of VH and VL regions surrounded the 'hydrophobic pocket'. This study provides a theory basis for improving antibody affinity, investigating antibody structure and analyzing the functions of VH and VL regions in antibody activity. | 周春 沈关心 朱慧芬 杨静 张悦 冯健南 沈倍奋 | 2000 | Journal of Huazhong University of Science and Technology(Medical Sciences)2000，20，1： | 3 |
| 10 | Isomerization of linear C5–C7 over Pt loaded on protonated fibrous silica@Y zeolite(Pt/HSi@Y)显示文摘A novel fibrous silica Y zeolite (HSi@Y) loaded with Pt has been studied based on its ability to produce protonic acid sites originating from molecular hydrogen. The Pt/HSi@Y was prepared using seed assisted crystallization followed by protonation and Pt-loading. The product formed had a spherical morphology with bicontinuous lamellar with a diameter in the range of 500-700 nm. The catalytic activity of the Pt/HSi@Y has been assessed based on light linear alkane (C5-C7) isomerization in a micro-catalytic pulse reactor at 423-623 K. A pyridine IR study confirmed that the introduction of fibrous silica on Y zeolite increased the Lewis acid sites corresponding with the formation of extra-framework Al which led to the generation of more protonic acid sites. A hydrogen adsorbed IR study showed that the protonic acid sites which act as active sites in the isomerization were formed via dissociative-adsorption of molecular hydrogen releasing electrons to the nearby Lewis acid sites. Thus, it is suggested that the presence of Pt and HSi@Y with a high number of Lewis acid as well as weak Bronsted acid sites improved the activity and stability in C5, C6 and C7 isomerization via hydrogen spill-over mechanism. | S.Triwahyono A.A.Jalil S.M.Izan N.S.Jamari N.A.A.Fatah | 2019 | Journal of Energy Chemistry2019，28，10： | 3 |
| 11 | An acidic polysaccharide with xylose branches from Porphyra yezoensis显示文摘An acidic polysaccharide (PY3) was isolated from the hot water extract of the red algae Porphyra yezoensis by successive column chromatographies over DEAE-cellulose and Sephadex G-200. PY3 with an average molecular weight of 1.8×105 was demonstrated to be composed of galactose (Gal), 3,6-anhydrogalactose (3,6-AnGal), 6-OSO3-galactose (6-OSO3-Gal) and xylose (Xyl) in an approximate molar ratio of 25:15:10:1. In view of Smith degradation and me-thylation and on the basis of spectral evidence including those of IR, GC, GC-MS, and 1H and 13C NMR, the most probable repeating unit of PY3 could be proposed as [(1-3)β-D-Gal(1- 4)α-L-3,6-AnGal]3-[1-3)β-D-Gal(1-4)α-L-6-OSO3-Gal]2 with a xylose moiety at the C6 of one of every twenty-five β-D-Gal residues. To our knowledge, PY3 was shown to be the first porphyran possessing occasional xylose branches. | ZHANG Weiyun CHEN Hao WANG Shuijuan XIA Zhonghao FEI Xiugeng TAN Renxiang | 2001 | Chinese Science Bulletin2001，46，3： | 3 |
| 12 | pH-sensitive and biodegradable charge-transfer nanocomplex for second near-infrared photoacoustic tumor imaging显示文摘The emerging technique of photoacoustic imaging,especially in the near infra-red(NIR)window,permits high resolution,deep-penetration,clinically reliable sensing.However,few contrast agents are available that can specifically respond to intricate biological environments,and which are biodegradable and biocompatible.Herein,we in troduce a new class of pH-sensitive orga nic photoacoustic con trast age nt that operates in the second NIR window(NIR-II,960-1,700 nm),which is derived from the self-assembled charge-transfer nanocomplex(CTN)by 3,3',5,5'-tetramethylbenzidine(TMB)and its dication structure(TMB++).The unique NIR-ll-responsive CTN can specifically respond to pH change in the physiological range and allows noninvasive and sensitive visualization of the tumor acidic microenvironment(e.g.at pH5)in mice with higher signal-to-noise ratio.The CTN is biodegradable under physiological conditions(e.g.pH 7.4),which alleviates the biosafety concern of nan oparticle accumulati on in vivo.These results clearly show the pote ntial of the TMB/TMB++-based CTN as a promisi ng pH-activated and biodegradable molecular probe for specific tumor photoacoustic imaging in the NIR-II region. | Zhimin Wang Paul Kumar Upputuri Xu Zhen Ruochong Zhang Yuyan Jiang Xiangzhao Ai Zhijun Zhang Ming Hu Zhenyu Meng Yunpeng Lu Yuanjing Zheng Kanyi Pu Manojit Pramanik Bengang Xing | 2019 | Nano Research2019，12，1： | 3 |
| 13 | Investigation of aggregation in solvent extraction of lanthanides by acidic extractants (organo-phosphorus and naphthenic acid)显示文摘Three acidic extractants (Ⅰ) di(2-ethylhexyl) phosphoric acid (HDEHP),(Ⅱ) 2-ethylhexyl phos-phonic acid mono-2-ethylhexyl ester (KEHPEHE) and (Ⅲ) naphthenic acid were employed in preparing the samples for the characterization of the coordination structure of lanthanlde-extractant complexes and the physicochemical nature of aggregates formed in the organic diluent of the solvent extraction systems.Photo correlation spectroscopy (PCS) re-suits on the aggregates formed by the partially saponified HDEHP in n -heptane showed that the hydrodynamic radius of the aggregates was comparable to the molecular dimensions of HDEHP.The addition of 2-octanol into the diluent,by which the mixed solvent was formed,increased the dimensions of the corresponding aggregates.Aggregates formed from the ianthamde ions and HDEHP in the organic phase of the extraction systems were found very unstable.In the case of naphthenic acid,PCS data showed the formation of w/o microemulsion from the saponified naphthenic acid in the | 周乃扶 吴瑾光 俞致健 王笃金 徐光宪 | 1997 | Science China Chemistry1997，40，1： | 3 |
| 14 | Isolated zinc in mordenite stabilizing carbonylation of dimethyl ether to methyl acetate显示文摘Herein, we prepared a series of H-Zn-mordenite (H-Zn-MOR) catalysts by adding zinc source into the initial sols during the synthesis of mordenite (MOR). The results indicated that isolated Zn ions were highly dispersed in the catalysts. The addition of zinc led to the increase of Si/Al in the framework of MOR,the change of the distribution of acid sites and the change of acid strength. We investigated the catalytic performance of the H-Zn-MOR catalysts and the HMOR catalysts for carbonylation of dimethyl ether to methyl acetate. The addition of zinc improved the catalytic performance and made the drop of the conversion over the Zn-0.003 and Zn-0.005 catalysts to be about the half of that over the HMOR catalyst.We attributed it to the change of the acid properties, which further change the rate of coke deposition. | Zhitao Zhang Na Zhao Kui Ma Qingpeng Cheng Jing Zhang Lirong Zheng Ye Tian Xingang Li | 2019 | Chinese Chemical Letters2019，30，2： | 3 |
| 15 | Structural basis of ALMT1-mediated aluminum resistance in Arabidopsis显示文摘The plant aluminum(Al)-activated malate transporter ALMT1 mediates the efflux of malate to chelate the Al in acidic soils and underlies the plant Al resistance.Here we present cryo-electron microscopy(cryo-EM)structures of Arabidopsis thaliana ALMT1(AtALMT1)in the apo,malate-bound,and Al-bound states at neutral and/or acidic pH at up to 3.0Åresolution.The AtALMT1 dimer assembles an anion channel and each subunit contains six transmembrane helices(TMs)and six cytosolicα-helices.Two pairs of Arg residues are located in the center of the channel pore and contribute to malate recognition.Al binds at the extracellular side of AtALMT1 and induces conformational changes of the TM1-2 loop and the TM5-6 loop,resulting in the opening of the extracellular gate.These structures,along with electrophysiological measurements,molecular dynamic simulations,and mutagenesis study in Arabidopsis,elucidate the structural basis for Al-activated malate transport by ALMT1. | Jiangqin Wang Xiafei Yu Zhong Jie Ding Xiaokang Zhang Yanping Luo Ximing Xu Yuan Xie Xiaoxiao Li Tian Yuan Shao Jian Zheng Wei Yang Jiangtao Guo | 2022 | Cell Research2022，32，1： | 3 |
| 16 | Evaluation and mapping of relative sensitivity of the terrestrial ecosystems to acidic deposition in Fujian显示文摘Based on the semi-quantitative approach, four environmental factors of sites (i.e. bedrock lithology, soil type, land use, and rainfall) were categorized, weighted and combined to determine and assess the relative sensed of the terrestrial ecosystems to acidic deposition in Fujian Province. Then the factors have been digital and combined to assign an overall value for each mesh square (16.77 km×18.39 km) by using the geographic information system (GIS). The results indicated that the most sensitive area in Fujian was mainly located in the southeast, and the least sensitive area was distributed sporadically in the east along the coast. Due to slow weathering rate of siliceous rocks, acid to weakly acid reactions of the soils, along with the greater percent of coniferous forests, more than 80 percent of the total area exhibits higher sensitivity classes (4-7). | 樊后保 梁慧燕 林德喜 陈世品 | 2000 | Journal of Forestry Research2000，11，1： | 2 |
| 17 | Vertical Variation of Nitrogen Fixers and Ammonia Oxidizers along a Sediment Profile in the Dajiuhu Peatland, Central China显示文摘To investigate the vertical variation of microbial functional groups particular nitrogen fixers and ammonia oxidizers, sediment samples from a 155 cm deep peat profile were collected from the acidic Dajiuhu Peatland and subsequently subjected to clone library construction and quantification. Results showed that nifH gene abundance varied between 105–108 copies per gram dry sediment and reduced gradually with depth. The abundances of ammonia oxidizing archaea(AOA) and ammonia oxidizing bacteria(AOB) abundance were generally comparable in each sample. More AOA was observed with a depth ?55 cm, whereas AOB was more abundant with a depth >55 cm. Phylogenetically nifH could be divided into 94 OTUs which mainly affiliated with ?-Proteobacteria. AOA were affiliated with Nitrosotalea from Group 1.1 a associated(nearly 90%) and Nitrososphaera from Group I.1 b. All AOB belonged to Nitrosospira. Notably, DJH11 with the depth of 50–55 cm was observed to have the highest abundance and the highest diversity of nitrogen fixers and ammonia oxidizers among all the samples. Pearson's correlation analysis showed a positive relationship between water content and p H with the nifH gene abundance. Our results offer the first insight about the microbial community composition and diversity involved in nitrogen cycles in the Dajiuhu Peatland. | Ying Xu Hongmei Wang Xing Xiang Ruicheng Wang Wen Tian | 2019 | Journal of Earth Science2019，30，2： | 2 |

| 20 | N/S co-doped 3D carbon framework prepared by a facile morphology-controlled solid-state pyrolysis method for oxygen reduction reaction in both acidic and alkaline media显示文摘Developing high-performance non-precious metal electrocatalysts for oxygen reduction reaction(ORR)is crucial for the commercialization of fuel cells and metal-air batteries.However,doped carbon-based materials only show good ORR activity in alkaline medium,and become less effective in acidic environment.We believe that an appropriate combination of both ionic and electronic transport path,and well dopant distribution of doped carbon-based materials would help to realize high ORR performance un-der both acidic and alkaline cond让ions.Accordingly,a nitrogen and sulfur co-doped carbon framework with hierarchical through-hole structure is fabricated by morphology-controlled solid-state pyrolysis of poly(aniline-co-2-ami no thiophenol)foam.The uniform high concentrations of nitrogen and sulfur,high intrinsic conductivity,and integrated three dimensional ionic and electronic transfer passageways of the 3D porous structure lead to synergistic effects in catalyzing ORR.As a result,the limiting current density of the carbonized poly(aniline-co-2-aminothiophenol)foam is equivalent to commercial Pt/C in acidic environment,and twice the latter in alkaline medium. | Juan Nong Min Zhu Kun He Aosheng Zhu Pu Xie Minzhi Rong Mingqiu Zhang | 2019 | Journal of Energy Chemistry2019，28，7： | 2 |
