4Crystal structures of D-psicose 3-epimerase from Clostridium cellulolyticum H10 and its complex with ketohexose sugars显示文摘D-Psicose 3-epimerase(DPEase)is demonstrated to be useful in the bioproduction of D-psicose,a rare hexose sugar,from D-fructose,found plenty in nature.Clostridium cellulolyticum H10 has recently been identified as a DPEase that can epimerize D-fructose to yield D-psicose with a much higher conversion rate when compared with the conventionally used DTEase.In this study,the crystal structure of the C.cellulolyticum DPEase was determined.The enzyme assembles into a tetramer and each subunit shows a(β/α)8 TIM barrel fold with a Mn2+metal ion in the active site.Additional crystal structures of the enzyme in complex with substrates/products(D-psicose,D-fructose,D-tagatose and D-sorbose)were also determined.From the complex structures of C.cellulolyticum DPEase with D-psicose and D-fructose,the enzyme has much more interactions with D-psicose than D-fructose by forming more hydrogen bonds between the substrate and the active site residues.Accordingly,based on these ketohexosebound complex structures,a C3-O3 proton-exchange mechanism for the conversion between D-psicose and D-fructose is proposed here.These results provide a clear idea for the deprotonation/protonation roles of E150 and E244 in catalysis.Hsiu-Chien Chan Yueming Zhu Yumei Hu Tzu-Ping Ko Chun-Hsiang Huang Feifei Ren Chun-Chi Chen Yanhe Ma Rey-Ting Guo Yuanxia Sun 2012Protein & Cell2012,3,2:6
5Anti-P-selectin lectin-EGF domain monoclonal antibody inhibits the maturation of human immature dendritic cells显示文摘Dendritic cells(DCs) are professinal antigen-presenting cells with the ability to initiate primary Tcell responses. While it iswell known that inflammatory stimuli induce the functional maturation of immature DCs, whether adhesion molecule selectins regulate DCmaturation is poorly understood. Using anti-P-selectin lectin-EGF domain monoclonal antibody (PsL-EGFmAb) that blocks the adhesionof P-, E-, and L-selectin, we demonstrate herein that selectins play important role in stimulating functional maturation of immature DCs.Immature DCs are generated from human cord blood CD34+hematopoietic stem/progenitor cells that were cultured in the presence of stemcell factor, Fms-like tyrosine-kinase-3 ligand, granulocyte-macrophage colony stimulating factor, and transform growth factor-β1. Whenstimulated with tumor necrosis factor-alpha(TNF-α), immature DCs differentiated into mature DCs, producing increased levels of costim-ulatory molecules and interleukin (IL)-12 and obtaining the ability to potently activate naive Tcells. Interestingly, in contrast to matureDCs derived from TNF-α-induced immature DC cultures without PsL-EGFmAb, immature DCs treated with PsL-EGFmAb for7 days werecompletely blocked their maturation, as evidenced by decreased expression of costimulatory molecules CD80, CD86, and CD83, inhibi-ted production of IL-12, and inability to activate naive Tcellsin vitro. Thus, blockade of selectins using PsL-EGFmAb will prove to bea valuable tool for the study of the molecuar mechanisms of DC maturation, as well as for the prevention and treatment of DC-mediated au-toimmunity.Tong Zhou Yanyu Zhang Guizhi Sun Yumei Zhang Dongqing Zhang Yapeng Zhao Nan Chen 2006上海交通大学学报(医学版)2006,26,5:5
6Animal diversities and characteristics of environmental change revealed by skeletons unearthed at Zhongba Site of Chongqing City,China显示文摘Nearly 200000 animal skeletons are unearthed in the Unit T0202 from Zhongba Site of Zhongxian County.According to the analysis of 129165 specimens,these skeletons may be classified into 5 kinds, namely,Mammalia,Osteichthys,Aves,Amphibian and Reptilia,which belong to 13 orders,28 families and 42 genera.In this paper,based on archeological dating and AMS 14 C data,through statistically analyzing the unearthed skeletons and studying the change of the smallest individual numbers,these research results detected the following:1)In almost all the time of 2370―200 BC,in Zhongba region, some animals distributed widely,such as Muntiacus sp,Elaphodus cephalophus and Muntiacus sp. inhabiting in glade and grassland,Scrofa sp.and Canis familiaris raised by the ancient people,rodentia rabbit and Rattus rattus,which suggested that a fairly good ecological environment of forest and grassland was preserved at that period and the predecessors began to raise domestic animals from 1750 to 1000 BC,which has lasted until today.2)Rhinoceros only lived during 2000―1750 BC,1000― 700 BC and 700―500 BC,which indicates that the ecological environment of grassland and wetland might be better in these phases.3)Macaca sp.and Ursus arctos appeared only after 1750―1000 BC, which may show that the forest condition is better for animals to live during 1750―200 BC.4)The smallest individual numbers of Bublus sp.,bos sp.and otters emerged during about 2370―1750 BC, which perhaps infers that water area during the early period was wider than that of the late period.5) Since skeletons of rhinoceros are discovered in strata of Zhongba Site during 2000―1750 BC and 1000―500 BC,according to the climate and ecology environment which rhinoceros live in now,the average annual temperature and precipitation during 2000―1750 BC and 1000―500 BC are supposed to be probably higher than that of today.Although Zhu Kezhen considered that the first low temperature period in the past 5000 years of China was between 1100 BC and 850 BC,massive pollen of Morus, Ulmus,Fagus,Quercus,Castanea,etc.were found in Dajiuhu peat at that time,which should indicate that the climate was still moderate for living things to live at least in Dajiuhu basin and Zhongba Site.6) Because skeletons of Gervus albirostris were unearthed during 310―200 BC at Zhongba Site,based onthe climate and the ecological environment those animals live in now,the average annual temperature and the average annual precipitation in Zhongba area between 310 BC and 200 BC should be lower than those of today,which is confirmed by the TOC research of Zhongba Site strata.ZHU Cheng MA ChunMei OUYANG Jie LI ZhongXuan YIN Qian SUN ZhiBin HUANG YunPing R.K.FLAD LI Lan LI YuMei 2008Chinese Science Bulletin2008,53,S1:4
7Valsartan Inhibited the Accumulation of Dendritic Cells in Rat Fibrotic Renal Tissue显示文摘为了在到 tubulointerstitial 纤维变性的老鼠残余肾和它的贡献观察树枝状的房间(DC ) 的累积,在 DC 上的 valsartan 的影响下面,一个老鼠残余肾模型被小计肾切除术建立。四个试验性的组被包括:正常,假冒,模型(SNx ) 和这个组与 Valsartan (SNxV ) 对待。老鼠分别地在星期 1,4 和 12 点被打死。CD1a+CD80+ DC 是由两倍 immunostaining 方法的 assayed,图象与 Axioplan 2 显微镜学被分析。P-selectin, TGF-1, -SMA, 骨胶原和 fibronectin 的表情被 immunohistochemistry 或 semiquantitative RT-PCR 分析,并且 tubulointerstitial firosis (TIF ) 的水平被获得。CD1a+CD80+ DC 逐渐地在肾的小管, interstitium 和容器之中被增加,特别在在在星期 12 点的模型组的 DC 的 interstitium,和数字在在星期 1 或 4 点的模型组是多于那的大部分。在 tubulointerstitial 区域和 TIF 的度的 P-selectin, TGF-1, -SMA, 骨胶原和 fibronectin 的表情在星期 12 点在模型组实质地被增加。在 interstitium 的 DC 的累积很好与肾的功能和 tubulointerstitial 纤维变性的前进的损失被联系。Valsartan 处理禁止了 DC 的本地累积并且稀释了肾的 tubulointerstitial 损坏。本地 DC 累积与跟随肾的脱离的 tubulointerstitial 纤维变性和肾的机能障碍有关。对血管收缩素的封锁可能是稀释肾的免疫煽动性的损害的一个有势力方法。Kaiyin Wu Tong Zhou Guizhi Sun Weiming Wang Yumei Zhang Yanyun Zhang Li Hao Nan Chen 2006Cellular & Molecular Immunology2006,3,3:4
8Pathogenesis and multidisciplinary management of medication-related osteonecrosis of the jaw显示文摘Medication-related osteonecrosis of the jaw(MRONJ)is a serious side effect of bone-modifying agents and inhibits angiogenesis agents.Although the pathogenesis of MRONJ is not entirely clear,multiple factors may be involved in specific microenvironments.The TGF-β1 signalling pathway may have a key role in the development of MRONJ.According to the clinical stage,multiple variables should be considered when selecting the most appropriate treatment.Therefore,the prevention and management of treatment of MRONJ should be conducted in patient-centred multidisciplinary team collaborative networks with oncologists,dentists and dental specialists.This would comprise a closed responsibility treatment loop with all benefits directed to the patient.Thus,in the present review,we aimed to summarise the pathogenesis,risk factors,imaging features,clinical staging,therapeutic methods,prevention and treatment strategies associated with MRONJ,which may provide a reference that can inform preventive strategies and improve the quality of life for patients in the future.Lina He Xiangyu Sun Zhijie Liu Yanfen Qiu Yumei Niu 2020International Journal of Oral Science2020,12,3:4
9Alleviating mechanical degradation of hexacyanoferrate via strain locking during Na^(+) insertion/extraction for full sodium ion battery显示文摘Generation of large strains upon Na^(+) intercalation is one of the prime concerns of the mechanical degradation of Prussian blue(PB)and its analogs.Structural construction from the atomic level is imperative to maintain structural stability and ameliorate the long-term stability of PB.Herein,an inter nickel hexacyanoferrate(NNiFCN)is successfully introduced at the out layer of iron hexacyanoferrate(NFFCN)through ion exchange to improve structural stability through compressive stress locking by forming NNiFCN shell.Furthermore,the kinetics of sodium ion diffusion is enhanced through the built-in electric pathway.The electrochemical performance is therefore significantly improved with a remarkable long-term cycling stability over 3,000 cycles at 500 mA·g^(–1) in the full sodium-ion batteries(SIBs)with a maximum energy density of 91.94 Wh·g^(–1),indicating that the core-shell structured NNiFCN/NFFCN could be the low-cost and high-performance cathode for full SIBs in large-scale EES applications.Jianguo Sun Hualin Ye Jin An Sam Oh Yao Sun Anna Plewa Yumei Wang Tian Wu Kaiyang Zeng Li Lu 2022Nano Research2022,15,3:3
10Interference of CsGPA1,theα-submit of G protein,reduces drought tolerance in cucumber seedlings显示文摘The G proteinα-subunit,GPA1,is an integral component of several signaling pathways in plants,including response to abiotic stress.However,the molecular mechanism behind these processes remains largely unknown in the cucumber plant(Cucumis sativus L.).In order to further understand the role of CsGPA1 in cucumber under drought stress,changes in plant growth,physiological parameters,and gene expression of CsAQPs were all measured under water stress induced by polyethylene glycol(PEG)using wild type(WT)and CsGPA1-interference(RNAi)cucumber seedlings.Our results demonstrated that the RNAi plants had lower drought tolerance,displaying seriously withered leaves,lower relative growth rate,lower root-shoot ratio,and lower root activity under drought stress compared to WT plants.Physiological studies indicated that the suppression of CsGPA1 weakened drought stress tolerance due to higherwater loss rate in the leaves,higher levels of hydrogen peroxide(H2O2),increased malondialdehyde(MDA)content,lower free proline content,lower soluble sugar content,lower soluble protein content,and decreased antioxidant enzyme activities.qRT-PCR analysis demonstrated that the interference of CsGPA1 up-regulated the expression of most AQP genes(except for CsPIP2;3 in leaves)and down-regulated the expression of CsPIP1;2,CsPIP1;4,CsPIP2;1,and CsPIP2;4 in roots under drought stress when compared to WT plants.Our results demonstrated that CsGPA1 could function as a positive regulator in drought stress response by decreasing the accumulation of reactive oxygen species(ROS),improving permeable potentials,and reducing water loss in cucumber plants.Yumei Liu Qinghua Du Longqiang Bai Mintao Sun Yansu Li Chaoxing He Jun Wang Xianchang Yu Yan Yan 2021Horticultural Plant Journal2021,7,3:3
11Derivation and characterization of human embryonic stem cell lines from poor quality embryos显示文摘Poor quality embryos discarded from in vitro fertilization (IVF) laboratories are good sources for deriving human embryonic stem cell (hESC) lines. In this study, 166 poor quality embryos donated from IVF centers on day 3 were cultured in a blastocyst medium for 2 days, and 32 early blastocysts were further cultured in a blastocyst optimum culture medium for additional 2 days so that the inner cell masses (ICMs) could be identified and isolated easily. The ICMs of 17 blastocysts were isolated by a mechanical method, while those of the other 15 blastocysts were isolated by immunosurgery. All isolated ICMs were inoculated onto a feeder layer for subcultivation. The rates of ICM at- tachment, primary ICM colony formation and the efficiency of hESC derivation were similar between the ICMs isolated by the two methods (P>0.05). As a result, four new hESC lines were established. Three cell lines had normal karyotypes and one had an unbalanced Robertsonian translocation. All cell lines showed normal hESC characteristics and had the differentiation ability. In conclusion, we established a stable and effective method for hESC isolation and culture, and it was confirmed that the mechanical isolation was an effective method to isolate ICMs from poor embryos. These results further indicate that hESC lines can be derived from poor quality embryos discarded by IVF laboratories.Weiqiang Liu, Yifei Yin, Xiaolin Long, Yumei Luo, Yonghua Jiang, Wenhong Zhang, Hongzi Du, Shaoying Li, Yuhong Zheng, Qing Li, Xinjie Chen, Baoping Liao, Guohong Xiao, Weihua Wang, Xiaofang Sun Guangzhou Key Laboratory of Reproductive and Genetics Institute of Gynecology and Obstetrics, The Third Affiliated Hospital of Guangzhou Medical College, Guangzhou 510150, China 2009Journal of Genetics and Genomics2009,36,4:3
12Nitrogen-doped Co_(3)O_(4) nanowires enable high-efficiency electrochemical oxidation of 5-hydroxymethylfurfural显示文摘Developing highly efficient and cost-effective catalysts for electrochemically oxidizing biomass-derived 5-hydroxymethylfurfural(HMF)into value-added 2,5-furandicarboxylic acid(FDCA)is of great importance.Herein,we report a controllable nitrogen doping strategy to significantly improve the catalytic activity of Co_(3)O_(4)nanowires for highly selective electro-oxidation of HMF into FDCA.The nitrogen doping leads to the generation of defects including nitrogen dopants and oxygen vacancies in Co_(3)O_(4)nanowires,which is conducive to the formation of catalytically active sites.As a result,the electro-oxidation potential for HMF is only 1.38 V(vs.RHE)when the current density reaches 50 mA/cm^(2).More importantly,the conversion rate of HMF is as high as 99.5%,and the yield of FDCA is up to 96.4%.Mengxiao Sun Yue Wang Chunsen Sun Yan Qi Jia Cheng Yumei Song Lixue Zhang 2022Chinese Chemical Letters2022,33,1:2
13Anterior limb lesions in bilateral internal capsules and memory function in patients with refractory obsessive-compulsive disorder显示文摘BACKGROUND: Previous studies have shown that lesions in the anterior limb of the internal capsule contribute to obsessive-compulsive symptoms in patients with refractory obsessive-compulsive disorder (OCD). However, few reports have addressed the effects of lesions in the anterior limb of the internal capsule on cognition, learning, and memory functions in patients with refractory OCD. OBJECTIVE: To investigate the degree of damage to memory tasks in refractory OCD patients following lesions to the anterior limb of the internal capsule. DESIGN, TIME AND SETTING: A case-controlled, observational study was performed at the Department of Functional Neurosurgery, Ruijin Hospital, Shanghai Jiao-Tong University, China from May 2007 to March 2008. PARTICIPANTS: A total of 10 refractory OCD patients were admitted to the Department of Functional Neurosurgery, Ruijin Hospital, Shanghai Jiao-Tong University, China from May 2007 to March 2008 and were recruited for this study. The OCD patients were of equal gender, with an average age of (25.1 ± 9.6) years. An additional 10 healthy volunteers were enrolled from a community of Shanghai City as controls; they were of equal gender and aged (25.1 ± 8.6) years. METHODS: A total of 10 refractory OCD patients were subjected to lesions in the anterior limbs of the bilateral internal capsules. Wechsler Memory Scale–Chinese Revision (WMS-CR, as a task of explicit memory) and the Nissen Version (serial reaction time task) software (SRTT, as a task of implicit memory) were applied to determine memory functions and learning performance in pre- and post-operative OCD patients and controls. MAIN OUTCOME MEASURES: WMS scores, reaction time in SRTT, and Yale-Brown obsessive compulsive scale scores were measured in pre- and post-operative OCD patients and controls. RESULTS: Compared to controls, the pre-operative OCD patients exhibited reduced memory task scores (P = 0.005), whereas scores for reciting numbers of backwards digits were greater (P = 0.000). Figure recall and associative memory were less in OCD patients at 1 week following surgery than in the pre-operative OCD patients (P = 0.042, P = 0.002, respectively). Reaction time in implicit SRTT was significantly longer in pre-operative OCD patients compared with controls and post-operative OCD patients (P = 0.01, P = 0.03, respectively). These results suggested ameliorated SRTT following neurosurgery. Yale-Brown Obsessive Compulsive Scale results revealed significantly improved OCD following lesions in the internal capsule (P = 0.04). Some post-operative OCD patients suffered from deficits in short-term memory and implicit memory. CONCLUSION: Lesions in anterior limbs of bilateral internal capsules improve obsessive-compulsive symptoms and implicit memory in OCD patients, but result in aggravated short-term memory deficits.Yumei Jiang Bomin Sun Xiaoping Wang Weifeng Zhang Xinfeng Zhao Lassonde MO 2010Neural Regeneration Research2010,5,12:2
14Effect of Particle Size on the Hysteretic Behavior and Magnetocaloric Effect of La_(0.5)Pr_(0.5)Fe_(11.4)Si_(1.6) Compound显示文摘Bulk La_(0.5)Pr_(0.5)Fe_(11.4)Si_(1.6) compound exhibits a large magnetic-entropy change △S_m of 28.1 J/(kg K) for a magnetic-field change from 0 to 1.5 T at the Curie temperature,T_C of 186 K,accompanied by a large magnetic hysteresis of 56 J/kg and a noticeable thermal hysteresis of about 1 K.If the bulk sample is ground into middle-size particles(30-60 μm),then the thermal hysteresis is almost eliminated and the magnetic hysteresis loss is decreased by 29%,while the large △S_m maintains.Especially,fine powder with an average size of 2 μm shows the same T_C as the bulk and does not lose stability.Meanwhile,a comparatively large △S_m of 13.9 J/(kg K) and a hysteresis reduction of 70%are attained.The hysteresis reduction can be ascribed to the decrease of internal strains and to the improvement of heat transfer due to the increase of the ratio of the surface area to the volume.Jiaohong Huang Naikun Sun Cuilan Liu Yumei Ge Tao Zhang Feng Liu Pingzhan Si 2014Acta Metallurgica Sinica(English Letters)2014,27,1:2
15Carbon and nitrogen stable isotope analyses of mammal bone fossils from the Zhongba site in the Three Gorges Reservoir region of the Yangtze River,China显示文摘Based on AMS 14 C dating data,carbon and nitrogen isotope analyses were conducted on mammal bone collagen of deer,cattle and pigs from the Zhongba site in the Three Gorges Reservoir region of the Yangtze River.These analyses were conducted to reconstruct palaeodiets of mammals,palaeoecology,palaeoenviroment and previous human activities in the study area.Results show that the collagen loss of bone did not change the in vivo isotopic composition of carbon and nitrogen stable isotopes,and most of the bone fossils were well preserved.The bone collagen of samples from deer had a mean δ 13 C of-23.1‰ and a mean δ 15 N of 4.7‰,suggesting that deer subsisted in a closed habitat and fed on branches and leaves.The bone collagen of cattle had a mean δ 13 C of-19.6‰ and a mean δ 15 N of 5.2‰,which indicates that cattle subsisted in an open habitat and fed on grasses and stems.The δ 13 C values show that both deer and cattle fed on C 3 plants and lived in the same ecosystem,but the t-test results show that deer δ 13 C and δ 15 N values were both more negative than those of cattle,indicating that they inhabited different niches.The δ 13 C and δ 15 N values of cattle partially overlapped those of deer,suggesting some competition in diets between them.The t-tests show that the δ 13 C and δ 15 N values of pigs were more positive than those of cattle and deer,which signifies that pigs occupied a higher trophic level compared to cattle and deer.The wide range of pig δ 13 C values demonstrates that pig trading had been taking place from early Neolithic Age to late Bronze Age.There were no significant differences in deer δ 13 C and δ 15 N values among different archaeological periods,making it clear that climatic,ecological and environmental conditions were kept relatively stable from 2200 to 4200 a BP.This stability may have been responsible for the extensive and complete cultural layers at the Zhongba site.The minimum number of samples required to estimate the mean δ 13 C values of deer,pigs and cattle are 8,73 and 16,respectively,and for mean δ 15 N values of deer,pigs and cattle,the minimum numbers are 4,5 and 6,respectively.TIAN XiaoSi ZHU Cheng SUN ZhiBin SHUI Tao HUANG YunPing FLAD Rowan Kimon LI YuMei 2011Chinese Science Bulletin2011,56,2:2

18Tunable Electronic and Magnetic Properties from Structure Phase Transition of Layered Vanadium Diselenide显示文摘The atomic geometry, structure stability, electronic and magnetic properties of VSe_2 were systematically investigated based on the density functional theory(DFT). Varying from 3D to 2D four VSe_2 structures, bulk 2H-VSe_2 and 1T-VSe_2, monolayer H-VSe_2 and T-VSe_2 are all demonstrated as thermodynamically stable by lattice dynamic calculations. More interestingly, the phase transition temperature is dramatically different due to the lattice size. Finally, owing to different crystal structures, H-VSe_2 is semimetallic whereas T-VSe_2 is totally metallic and also they have different magnetic moments. Our main argument is that being exfoliated from bulk to monolayer, 2H-VSe_2 transforms to T-VSe_2, accompanied by both semimetallic-metallic transition and dramatic magnetic moment variation. Our calculations provide a novel structure phase transition and an efficient way to modulate the electronic structure and magnetic moment of layered VSe_2, which suggests potential applications as high-performance functional nanomaterial.张会 SUN Liting DAI Yumei TONG Chuanjia 韩笑 2017Journal of Wuhan University of Technology(Materials Science)2017,32,3:1
19The application of the entropy-based statistic for genomic association study of QTL显示文摘An entropy-based statistic TPE has been proposed for genomic association study for disease-susceptibility locus. The statistic TPE may be directly adopted and/or extended to quantitative-trait locus (QTL) mapping for quantitative traits. In this article, the statistic TPE was extended and applied to quantitative trait for association analysis of QTL by means of selective genotyping. The statistical properties (the type I error rate and the power) were examined under a range of parameters and population-sampling strategies (e.g.,various genetic models, various heritabilities, and various sample-selection threshold values) by simulation studies. The results indicated that the statistic TPE is robust and powerful for genomic association study of QTL. A simulation study based on the haplotype frequencies of 10 single nucleotide polymorphisms (SNPs) of angiotensin-I converting enzyme genes was conducted to evaluate the performance of the statistic TPE for genetic association study.Yang Xiang Yumei Li Zaiming Liu Zhenqiu Sun 2008Journal of Genetics and Genomics2008,35,3:1
