1Impact of Accessibility on Housing Prices in Dalian City of China Based on a Geographically Weighted Regression Model显示文摘This paper studies the relationship between accessibility and housing prices in Dalian by using an improved geographically weighted regression model and house prices, traffic, remote sensing images, etc. Multi-source data improves the accuracy of the spatial differentiation that reflects the impact of traffic accessibility on house prices. The results are as follows: first, the average house price is 12 436 yuan(RMB)/m^2, and reveals a declining trend from coastal areas to inland areas. The exception was Guilin Street, which demonstrates a local peak of house prices that decreases from the center of the street to its periphery. Second, the accessibility value is 33 minutes on average, excluding northern and eastern fringe areas, which was over 50 minutes. Third, the significant spatial correlation coefficient between accessibility and house prices is 0.423, and the coefficient increases in the southeastern direction. The strongest impact of accessibility on house prices is in the southeastern coast, and can be seen in the Lehua, Yingke, and Hushan communities, while the weakest impact is in the northwestern fringe, and can be seen in the Yingchengzi, Xixiaomo, and Daheishi community areas.YANG Jun BAO Yajun ZHANG Yuqing LI Xueming GE Quansheng 2018Chinese Geographical Science2018,28,3:10
2Polymorphisms of three gene-derived STS on pig chromosome 13q41 are associated with susceptibility to enterotoxigenic Escherichia coli F4ab/ac in pigs显示文摘Neonatal diarrhea caused by enterotoxigenic Escherichia coli(ETEC)F4 is a common and serious disease,resulting in significant economical loss in the pig industry.The locus encoding ETEC F4 receptor has been mapped to pig chromosome(SSC)13q41,and one of the most significantly linked markers is S0075.In this study,we selected three genes including SLC12A8,MYLK and KPNA1 from a chromosomal region flanking S0075 on SSC13 to develop pig specific sequence tagged sites(STS). Seven single nucleotide polymorphisms were identified in the three pig STS using DNA of four full-sib susceptible and resistant animals in a White Duroc×Erhualian intercross.All grandparents,parents and 755 offspring in the intercross were genotyped for three polymorphisms,including SLC12A8 g.159A>G,MYLK g.1673A>G and KPNA1 g.306A>G.Family-based transmission disequilibrium test(TDT) revealed that all polymorphisms and the corresponding haplotypes are significantly associated with ETEC F4ab/ac(especially F4ac)brush border adhesion phenotypes,indicating that these polymor- phism are in linkage disequlibrium with causal mutation(s)of the gene encoding ETEC F4ab/ac receptor. Our results strengthen the evidence for the involvement of SSC13q41 in high acquiring risk of ETEC F4ab/ac infection,and provide novel polymorphic markers for fine mapping of the ETEC F4ab/ac receptor locus.HUANG Xiang 1 ,REN Jun 1 ,YAN XueMing 1,2 ,PENG QiuLing 1 ,TANG Huan 1 ,ZHANG Bo 1 ,JI HuaYuan 1 , YANG ShuJin1&HUANG LuSheng 1 1Key Laboratory for Animal Biotechnology of Jiangxi Province and the Ministry of Agriculture of China,Jiangxi Agricultural University, Nanchang 330045,China 2Department of Biology,Nanchang University of Science and Technology,Nanchang 330038,China 2008Science China(Life Sciences)2008,51,7:8
3A Geochemical Study of an REE-rich Carbonatite Dyke at Bayan Obo,Inner Mongolia,Northern China显示文摘An REE-rich carbonatite dyke was found in Dulahala, close to the Bayan Obo superlarge REE-Nb-Fe mineral deposit in Inner Mongolia, northern China. The REE content in the dyke varies greatly, from 1% up to 20% (wt), which might constitute rich REE ores. Light REEs in the carbonatite are enriched and highly fractionated relative to heavy REEs and there is no Eu anomaly. The REE and trace element distribution patterns of the carbonatite are identical to those of fine-grained dolomite marble which is the host rock of the Bayan Obo REE-Nb-Fe superlarge mineral deposit. This indicates a petrogenetic linkage between the REE-rich carbonatite and the mineralizations in this region.YANG Xueming ZHENG Yongfei YANG Xiaoyong ZHANG Peishan M.J.LE BAS 2000Acta Geologica Sinica(English Edition)2000,74,3:7
4Metallogenic geochemistry of Sb-mineralization in southern margin of North China platform显示文摘1 Geological setting THE Sb mineralization zone in the south margin of North China platform is located in the transitional edgeof North China plate and Yangtze plate, belonging to Qinling fold system, whose tectonic line is inNWW-SEE direction regionally. Because of the huge compression caused by the collision of the twoplates, the rocks undergone strong deformation and metamorphism have very complicated structures. Theregional deep fault-Shuanghuaishu fault-controls Sb-mineralization zone belt, and all the Sb-oredeposits or mineralized spots appear alone at the very southern margin of the fault. The lithostragraphirunits in the mineralized zone are relatively simple, mainly composed of Jiebei Group (Pt2J2) of QinglingFormation (with middle-high metamorphsim) and the upper Triassic system (with little metamorphism).YANG Xiaoyong~1, YANG Xueming~1, ZHANG Jianjun~2, CAO Gaoshe~2 and ZHANG Zhengwei~2 1.

5Effects of Tillage Management on Infiltration and Preferential Flow in a Black Soil, Northeast China显示文摘The impacts of no-tillage (NT) and moldboard plough (MP) managements on infiltration rate and preferential flow were characterized using a combined technique of double-ring device and dye tracer on a black soil (Mollisols) in Northeast China. The objective of this study is to evaluate how tillage practices enhance soil water infiltration and preferential flow in favor of soil erosion control in the study area. The steady infiltration rates under NT management are 1.6 and 2.1 times as high as those under MP management in the 6th and 8th years of the tillage management in place, while the infiltrated water amounts under NT management are 1.4 and 2.0 times as high as those under MP management, respectively. The depth of methylene blue penetrated into NT soil increases from 43cm in the 6th year to 57cm in the 8th year, which are 16cm and 19cm deeper than those in MP soil, respectively. The results of morphologic image show that more biological macro-pores occur in NT soil than in MP soil. These macro-pores play a key role in enhancing preferential flow in NT soil, which in turn promotes water infiltration through preferential pathways in NT soil. The results are helpful to policy-making in popularizing NT and have the implications for tillage management in regard to soil erosion control in black soil region of China.FAN Ruqin ZHANG Xiaoping YANG Xueming LIANG Aizhen JIA Shuxia CHEN Xuewen 2013Chinese Geographical Science2013,23,3:6

7Development and validation of an analytical method for detecting chlorantraniliprole residues in fresh tea leaves显示文摘An efficient method using multiwalled carbon nanotubes(MWCNTs)as dispersive solid-phase extraction sorbent was established for determining chlorantraniliprole residues in fresh tea leaves,which are known to be a troublesome matrix containing abundant pigments,via gas chromatography with an electron capture detector.Acetonitrile was used as the extraction solvent,with sodium chloride enhancing the analyte partition in the organic phase.The optimal mixture of MWCNTs and primary secondary amine(PSA)was based on the distribution of the target analyte recovery and on the clean-up efficiency;while matrix-matched calibration was recommended to combat the matrix effect.Mean recoveries of 95.2%–108.8%were obtained with intraday and interday precisions of less than 7.9%and 10.3%,respectively.Good linearity was observed for concentrations of 0.02–1.0 mg/kg with a correlation coefficient of 0.9984.The limits of detection and quantification were 0.005 mg/kg and 0.02 mg/kg,respectively.The method was employed to investigate the dissipation dynamics of chlorantraniliprole in fresh tea leaves with real field samples.Consequently,the dissipation rates of chlorantraniliprole in fresh tea leaves followed pseudo-first-order kinetics with a half-life of 1.9 d,and the average chlorantraniliprole residue content was below 0.02 mg/kg with a harvest withholding period of 14 d.Tengfei Liu Minghui Dong Fengjie Zhou Daifeng Yang Xueming Zhang 2019Food Science and Human Wellness2019,8,4:5
8Aquaporin 5 is degraded by autophagy in diabetic submandibular gland显示文摘Autophagy is a catabolic process which is involved in the development of many diseases including diabetes mellitus and its complications. Hyposalivation is a common complication of diabetes mellitus, whereas its mechanism remains unclear. Here, we observed that the stimulated salivary flow rate of SMG was significantly decreased in db/db mice, a diabetic mice model. The expressions of aquaporin 5(AQP5), a water channel protein, were decreased, whereas the m RNA level of AQP5 was increased in SMGs of both diabetic patients and mice. Under transmission electron microcope, more autophagosomes were detected in diabetic SMGs. Expressions of autophagy related proteins LC3 II, Beclin-1 and ATG5 were increased, meanwhile autophagy substrate p62 was decreased in SMGs of diabetic patients and mice, indicating that autophagy was activated in diabetic SMG.Double immunofluorescence staining showed that the colocalization of AQP5 and LC3 was increased in SMGs of diabetic mice.In cultured SMG-C6 cells, high glucose(HG), but not high osmotic pressure, reduced AQP5 protein expression and induced autophagy. Moreover, inhibition of autophagy by 3-methyladenin, an autophagy inhibitor, or by autophagy-related gene 5 siRNA, decreased HG-induced AQP5 reduction in SMG-C6 cells. Additionally, the expression of p-p85, p-Akt and p-mTOR were decreased in HG-treated SMG-C6 cells. Pretreatment with 740 Y-P, a PI3 K agonist, significantly suppressed HG-induced autophagy and AQP5 degradation. Taken together, these results indicate that autophagy plays a crucial role in AQP5 degradation in diabetic SMG via PI3 K/Akt/mTOR signaling pathway, which contributes to the dysfunction of diabetic SMG. Our study provides a novel mechanism of diabetic hyposalivation.Yan Huang Xijin Shi Qianying Mao Yan Zhang Xin Cong Xueming Zhang Zhejing Zhang Liling Wu Ruolan Xiang Guangyan Yu 2018Science China(Life Sciences)2018,61,9:5
9miR-155 aggravates impaired autophagy of pancreatic acinar cells through targeting Rictor显示文摘The aim of this study was to investigate the role and mechanism of miR-155 in regulating autophagy in a caerulein-induced acute pancreatitis(AP)cellular model.GFP-LC3 immunofluo-rescence assay was performed to detect autophagy vesicle formation in pancreatic acinar cell line AR42J.AR42J cells were transfected with miR-155 mimic,inhibitor,and corresponding controls to explore the effect of miR-155 on autophagy.The protein levels of LC3-I,LC3-11,Beclin-1,and p62 were analyzed by western blot analysis.Dual-luciferase reporter assay was performed to verify the interaction between miR-155 and Rictor(RPTOR independent companion of MTOR complex 2).The results showed that caerulein treatment induced impaired autophagy as evi-denced by an increase in the accumulation of p62 together with LC3-11 in AR42J cells,accompanied by miR-155 upregulation.Furthermore,miR-155 overexpression aggravated,whereas miR-155 silencing reduced the caerulein-induced impairment of autophagy.Mechanistically,Rictor was confirmed to be a direct target of miR-155,which could rescue the miR-155 overexpression-mediated aggravation of im paired autophagy.Collectively,these findings indicate that miR-155 aggravates impaired autophagy in caerulein-treated pancreatic acinar cells by targeting Rictor.Xueming Zhang Jiangtao Chu Haijun Sun Dali Zhao Biao Ma Dongbo Xue Weihui Zhang Zhituo Li 2020Acta Biochimica et Biophysica Sinica2020,52,2:4
10Serum osmolality and ions,and gill Na^(+)/K^(+)-ATPase of spottedtail goby Synechogobius ommaturus(R.)in response to acute salinity changes显示文摘This study was carried out to determine the effects of abrupt salinity change on osmoregulatory ability of the spottedtail goby Synechogobius ommaturus.720 juvenile fish(65.3±11.8 g)were transferred to 200 L tanks(with 40 juveniles in each tank),in which salinities were abruptly changed from 10 to 20,30,40,50 and freshwater.Survival rate,serum osmolality,electrolytes(Na^(+),Cl^(-),and K^(+))and gill Na^(+)/K^(+)-ATPase(NKA)activity were assessed successively in 528 h.Results showed serum osmolality,ion concentrations and gill Na^(+)/K^(+)-ATPase activity increased significantly when fish were transferred to salinity 40 and 50 and all fish in these groups died by the end of the experiment.Serum osmolality,Na^(+),Cl^(-)and K^(+)in fish transferred to a salinity of 20,30 and freshwater were not affected and no mortality was detected.Compared with the control group,a significantly decrease of NKA activity happened in the freshwater group,but the activity in 20 and 30 groups was not affected significantly.The results indicated that S.ommaturus could adapt rapidly and maintain homeostasis in a wide range of salinities(from freshwater to salinity 30)and this species may be suitable for aquaculture in estuarine and coastal areas where rapid salinity fluctuations commonly occur.Chun Shui Yonghai Shi Xueming Hua Zhonghua Zhang Haiming Zhang Genhai Lu Yongde Xie 2018Aquaculture and Fisheries2018,3,2:4
11Dynamical resonance in F+H_2 chemical reaction and rotational excitation effect显示文摘Reaction resonance is a frontier topic in chemical dynamics research,and it is also essential to the understanding of mechanisms of elementary chemical reactions.This short article describes an im- portant development in the frontier of research.Experimental evidence of reaction resonance has been detected in a full quantum state resolved reactive scattering study of the F+H2 reaction.Highly accurate full quantum scattering theoretical modeling shows that the reaction resonance is caused by two Feshbach resonance states.Further studies show that quantum interference is present between the two resonance states for the forward scattering product.This study is a significant step forward in our understanding of chemical reaction resonance in the benchmark F+H2 system.Further experimental studies on the effect of H2 rotational excitation on dynamical resonance have been carried out.Dy- namical resonance in the F+H2(j=1)reaction has also been observed.YANG XueMing XIE DaiQian ZHANG DongHui 2007Chinese Science Bulletin2007,52,8:4
12Effects of cooling rate on the microstructure and electrical properties of Dy_2O_3-doped ZnO-based varistor ceramics显示文摘The microstructure, electrical properties, and density of Dy2O3-doped ZnO-based varistor ceramics, prepared us-ing high-energy ball milling (HEBM) and sintered at 800°C, were investigated by increasing the cooling rate in the order of H (slow cooling in furnace) → L (cooling in furnace) → K (cooling in air). With the increase in cooling rate, the grain size and density decreased, the breakdown voltage (V1 mA / mm) increased, and the nonlinear coefficient (α) and leakage current (IL) exhibited extremum. The sample with the cooling type L showed the best properties with the breakdown voltage of 2650 V/mm, α of 20.3, IL of 5.2 μA, and density of 5.42 g/cm3. The barrier height (φB), donor concentration (Nd), density of the interface states (Ns), and barrier width (ω) all exhibited extremum during the alteration in cooling rate. The different relative amount of Bi-rich phase and its distribution as well as the characteristic parameters of grain boundary, resulting from the alteration of cooling rate, led to the changes in the properties of varistor ceramics.LIU Hongyu KONG Hui JIANG Dongmei SHI Wangzhou MA Xueming ZHANG Huining 2007Rare Metals2007,26,1:4
13Optimization of a synthetic medium for ethanol production by xylose-fermenting Zymomonas mobilis using response surface methodology显示文摘A synthetic medium for ethanol production by recombinant xylose-fermenting Zymomonas mobilis was optimized using Plackett-Burman(PB) design and response surface methodology(RSM).The effects of 19 medium components were investigated by PB design.Eight of these components were determined to have significant effects on ethanol production.The statistical model was constructed via central composite design(CCD) using five selected variables,including xylose,trisodium citrate,choline chloride,pyridoxine,and thiamine.The validity of the developed model was verified.The ethanol concentration in the optimized medium was 6.7% higher than in the RM medium.The optimized medium was then simplified to give the final synthetic medium(S2),in which the ethanol concentration was 20.7% higher than in the RM medium.Xylose and trisodium citrate were the key medium components influencing ethanol production,while calcium pantothenate was the only growth factor required by recombinant Z.mobilis.Ethanol production and growth response were directly proportional to the logarithm of the concentration of trisodium citrate in the range of 0.1-1.6 g/L.DONG HuiNa ZHAO XueMing MA YuanYuan ZHANG MinHua 2012Chinese Science Bulletin2012,57,28:3
14Plasticity of language pathways in patients with low-grade glioma A diffusion tensor imaging study显示文摘Knowledge of the plasticity of language pathways in patients with low-grade glioma is important for neurosurgeons to achieve maximum resection while preserving neurological function. The current study sought to investigate changes in the ventral language pathways in patients with low-grade glioma located in regions likely to affect the dorsal language pathways. The results revealed no significant difference in fractional anisotropy values in the arcuate fasciculus between groups or between hemispheres. However, fractional anisotropy and lateralization index values in the left inferior longitudinal fasciculus and lateralization index values in the left inferior fronto-occpital fasciculus were higher in patients than in healthy subjects. These results indicate plasticity of language pathways in patients with low-grade glioma. The ventral language pathways may perform more functions in patients than in healthy subjects. As such, it is important to protect the ventral language pathways intraoperatively.Gang Zheng Xiaolei Chen Bainan Xu Jiashu Zhang Xueming Lv Jinjiang Li Fangye Li Shen Hu Ting Zhang Ye Li 2013Neural Regeneration Research2013,8,7:3
15Development of a CLDN18.2-targeting immuno-PET probe for non-invasive imaging in gastrointestinal tumors显示文摘Claudin18.2(CLDN18.2)is a tight junction protein that is overexpressed in a variety of solid tumors such as gastrointestinal cancer and oesophageal cancer.It has been identified as a promising target and a potential biomarker to diagnose tumor,evaluate efficacy,and determine patient prognosis.TST001 is a recombinant humanized CLDN18.2 antibody that selectively binds to the extracellular loop of human Claudin18.2.In this study,we constructed a solid target radionuclide zirconium-^(89)(^(89)Zr)labled-TST001 to detect the expression of in the human stomach cancer BGC823CLDN18.2 cell lines.The[^(89)Zr]Zr-desferrioxamine(DFO)-TST001 showed high radiochemical purity(RCP,>99%)and specific activity(24.15±1.34 GBq/mmol),and was stable in 5%human serum albumin,and phosphate buffer saline(>85%RCP at 96 h).The EC_(50) values of TST001 and DFO-TST001 were as high as 0.413±0.055 and 0.361±0.058 nM(P>0.05),respectively.The radiotracer had a significantly higher average standard uptake values in CLDN18.2-positive tumors than in CLDN18.2-negative tumors(1.11±0.02 vs.0.49±0.03,P=0.0016)2 days post injection(p.i.).BGC823CLDN18.2 mice models showed high tumor/muscle ratios 96 h p.i.with[^(89)Zr]Zr-DFO-TST001 was much higher than those of the other imaging groups.Immunohistochemistry results showed that BGC823CLDN18.2 tumors were highly positive(+++)for CLDN18.2,while those in the BGC823 group did not express CLDN18.2().The results of ex vivo biodistribution studies showed that there was a higher distribution in the BGC823CLDN18.2 tumor bearing mice(2.05±0.16%ID/g)than BGC823 mice(0.69±0.02%ID/g)and blocking group(0.72±0.02%ID/g).A dosimetry estimation study showed that the effective dose of[^(89)Zr]Zr-DFO-TST001 was 0.0705 mSv/MBq,which is within the range of acceptable doses for nuclear medicine research.Taken together,these results suggest that Good Manufacturing Practices produced by this immuno-positron emission tomography probe can detect CLDN18.2-overexpressing tumors.Yan Chen Xingguo Hou Dapeng Li Jin Ding Jiayue Liu Zilei Wang Fei Teng Hongjun Li Fan Zhang Yi Gu Steven Yu Xueming Qian Zhi Yang Hua Zhu 2023Journal of Pharmaceutical Analysis2023,13,4:2
16Direct experimental detection of hydrogen radicals in non-oxidative methane catalytic reaction显示文摘Non-oxidative conversion of methane to olefins,aromatics and hydrogen(MTOAH) has been reported recently over metal single sites such as iron and platinum.The reaction was proposed to involve catalytic activation of methane followed by gas phase C-C coupling of methyl radicals.This study using H atom Rydberg Tagging time-of-flight technique provides direct experimental evidence for the formation of hydrogen radicals during MTOAH reaction over a catalytic quartz wall reactor containing embedded iron species(denoted as Fe-reactor).Fe-reactor gives 7.3% methane conversion at 1273 K with 41.2% selectivity toward C2(ethane,ethylene and acetylene) and 31.8% toward BTX(benzene,toluene and xylene),respectively.The enhancing effects of hydrogen radicals on overall MTOAH performance are validated by cofeeding hydrogen donor benzene,which provides an additional route of methane activation apart from catalytic activation.Jianqi Hao Pierre Schwach Lulu Li Xiaoguang Guo Junben Weng Hailei Zhang Hao Shen Guangzong Fang Xin Huang Xiulian Pan Chunlei Xiao Xueming Yang Xinhe Bao 2021Journal of Energy Chemistry2021,30,1:2
17Intraoperative diffusion tensor imaging predicts the recovery of motor dysfunction after insular lesions显示文摘Insular lesions remain surgically challenging because of the need to balance aggressive resection and functional protection. Motor function deficits due to corticospinal tract injury are a common complication of surgery for lesions adjacent to the internal capsule and it is therefore essential to evaluate the corticospinal tract adjacent to the lesion. We used diffusion tensor imaging to evaluate the corticospinal tract in 89 patients with insular lobe lesions who underwent surgery in Chinese PLA General Hospital from February 2009 to May 2011. Postoperative motor function evaluation revealed that 57 patients had no changes in motor function, and 32 patients suffered motor dysfunction or aggravated motor dysfunction. Of the affected patients, 20 recovered motor function during the 6-12-month follow-up, and an additional 12 patients did not recover over more than 12 months of follow-up. Following reconstruction of the corticospinal tract, fractional anisotropy comparison demonstrated that preoperative, intraoperative and follow-up normalized fractional anisotropy in the stable group was higher than in the transient deficits group or the long-term deficits group. Compared with the transient deficits group, intraoperative normalized fractional anisotropy significantly decreased in the long-term deficits group. We conclude that intraoperative fractional anisotropy values of the corticospinal tracts can be used as a prognostic indicator of motor function outcome.Jinjiang Li Xiaolei Chen Jiashu Zhang Gang Zheng Xueming Lv Fangye Li Shen Hu Ting Zhang Bainan Xu 2013Neural Regeneration Research2013,8,15:2
18Boosted photoreduction of diluted CO_(2) through oxygen vacancy engineering in NiO nanoplatelets显示文摘Converting carbon dioxide(CO_(2))to diverse value-added products through photocatalysis can validly alleviate the critical issues of greenhouse effect and energy shortages simultaneously.In particular,based on practical considerations,exploring novel catalysts to achieve efficient photoreduction of diluted CO_(2) is necessary and urgent.However,this process is extremely challenging owing to the disturbance of competitive adsorption at low CO_(2) concentration.Herein,we delicately synthesize oxygen vacancy-laden NiO nanoplatelets(r-NiO)via calcination under Ar protection to reduce diluted CO_(2) through visible light irradiation(>400 nm)assisted by a Ru-based photosensitizer.Benefitting from the strongly CO_(2) adsorption energy of oxygen vacancies,which was confirmed by density functional calculations,the r-NiO catalysts exhibit higher activity and selectivity(6.28×10^(3)µmol·h^(−1)·g^(−1);82.11%)for diluted CO_(2)-to-CO conversion than that of the normal NiO(3.94×10^(3)µmol·h^(−1)·g^(−1);65.26%).Besides,the presence of oxygen vacancies can also promote the separation of electron-hole pairs.Our research demonstrates that oxygen vacancies could act as promising candidates for photocatalytic CO_(2) reduction,offering fundamental guidance for the actual photoreduction of diluted CO_(2) in the future.Weiyi Chen Xueming Liu Bin Han Shujie Liang Hong Deng Zhang Lin 2021Nano Research2021,14,3:2
19Identification of EGF as an Important Regulator for Promoting CYP3A4 Expression in Human Embryonic Stem Cell-Derived Hepatocytes Using TALEN-Based Gene Targeting显示文摘Functional human hepatocytes are one of the most significant tools for studying drug absorption,distribution,metabolism and excretion/toxicity (ADME/Tox),especially for applications in preclinical drug development (Sahi et al.,2010;Godoy et al.,2013).They provide the closest in vitro model to the human liver and the only model that mimics the drug metabolic profiles found in vivo.However,these cells lose their metabolic function rapidly and dramatically during the in vitro culture process,which largely hinders their wider application in drug development (Sahi et al.,2010;Godoy et al.,2013).To overcome this obstacle,it is important to regulate the activities of key genes which are responsible for the detoxification metabolic function of human hepatocytes.Ming YinaCollege of Veterinary Medicine Jilin University Huan Yang Xiaohua Su Ziyi Li Zhanpeng Yue Xueming Zhang Da Sun Yan Shi Dexue Li 2014Journal of Genetics and Genomics2014,41,6:2
