3Overexpression of blueberry FLOWERING LOCUS T is associated with changes in the expression of phytohormone-related genes in blueberry plants显示文摘Flowering locus T(FT)is a primary integrator in the regulation of plant flowering.Overexpressing a blueberry(Vaccinium corymbosum L.)FT gene(VcFT)(herein VcFT-OX)resulted in early flowering and dwarfing in‘Aurora’plants(herein‘VcFT-Aurora’).In this study,we found that VcFT-OX reduced shoot regeneration from leaf explants.To investigate the potential roles of the phytohormone pathway genes associated with VcFT-OX,differentially expressed(DE)genes in leaf tissues of‘VcFT-Aurora’plants were annotated and analyzed using non-transgenic‘Aurora’plants as a control.Three DE floral genes,including the blueberry SUPPRESSOR of Overexpression of constans 1(VcSOC1)(gibberellin related),Abscisic acid responsive elements-binding factor 2(VcABF2)and protein related to ABI3/VP1(VcABI3/VP1)(ethylene-related),are present under both the phytohormone-responsive and the dwarfing-related Gene Ontology terms.The gene networks of the DE genes overall showed the molecular basis of the multifunctional aspects of VcFT overexpression beyond flowering promotion and suggested that phytohormone changes could be signaling molecules with important roles in the phenotypic changes driven by VcFT-OX.Xuan Gao Aaron E Walworth Charity Mackie Guo-qing Song 2016Horticulture Research2016,3,1:6
4Toxicity of Graphene Quantum Dots in Zebrafish Embryo显示文摘Objective To evaluate the bio-safety of graphene quantum dots(GQDs), we studied its effects on the embryonic development of zebrafish. Methods In vivo, biodistribution and the developmental toxicity of GQDs were investigated in embryonic zebrafish at exposure concentrations ranging from 12.5-200 μg/m L for 4-96 h post-fertilization(hpf). The mortality, hatch rate, malformation, heart rate, GQDs uptake, spontaneous movement, and larval behavior were examined. Results The fluorescence of GQDs was mainly localized in the intestines and heart. As the exposure concentration increased, the hatch and heart rate decreased, accompanied by an increase in mortality. Exposure to a high level of GQDs(200 μg/mL) resulted in various embryonic malformations including pericardial edema, vitelline cyst, bent spine, and bent tail. The spontaneous movement significantly decreased after exposure to GQDs at concentrations of 50, 100, and 200 μg/mL. The larval behavior testing(visible light test) showed that the total swimming distance and speed decreased dose-dependently. Embryos exposed to 12.5 μg/mL showed hyperactivity while exposure to higher concentrations(25, 50, 100, and 200 μg/mL) caused remarkable hypoactivity in the light-dark test. Conclusion Low concentrations of GQDs were relatively non-toxic. However, GQDs disrupt the progression of embryonic development at concentrations exceeding 50 μg/mL.WANG Zhen Guo ZHOU Rong JIANG Dan SONG Jing E XU Qian SI Jing CHEN Yun Ping ZHOU Xin GAN Lu LI Jian Zhen ZHANG Hong LIU Bin 2015Biomedical and Environmental Sciences2015,28,5:6
5A comparison of surgical efficacy between a 1.8-mm microincision and 3.2-mm and 5.5-mm incisions for phacoemulsification显示文摘Phacoemulsification is a commonly used surgical method in cataract surgery. This paper observes and compares the surgical efficacy of three incisions of different length for phacoemulsification to identify the optimal method for cataract surgery. Ninety patients were enrolled in the present study and divided into three groups. The 1.8-mm group received Bausch & Lomb MI60 foldable intraocular lens(IOL) implantation(n=30), 3.2-mm group received Bausch & Lomb Akreos AO foldable lens implantation(n=30), and 5.5-mm group received Alcon TYPE 05 rigid IOL implantation(n=30). Visual acuity, Oculyzer-based anterior segment analysis, and corneal endothelial cell count before surgery, and 3, 7, 30, and 90 d after surgery were recorded and compared. Pseudophakic accommodation three days, one week, one month, and three months after surgery was determined. Intraoperative ultrasound time and ultrasonic energy were recorded. It was finally concluded that for phacoemulsification with the same phaco tip, a 1.8-mm microincision can lead to quicker recovery of visual acuity, more stable astigmatism, and higher pseudophakic accommodation than conventional incision.E Song Xin Li Ming-Chao Bi Hua Ren Dan Wang Zhi-Hua Cui Wei Yang Hui Shi Ya-Bin Sun 2018International Journal of Ophthalmology(English edition)2018,11,3:4
6A Novel Model of Predicting Archie's Cementation Factor from Nuclear Magnetic Resonance(NMR) Logs in Low Permeability Reservoirs显示文摘The resistivity experimental measurements of core samples drilled from low permeability reservoirs of Ordos Basin,Northwest China,illustrate that the cementation factors are not agminate,but vary from 1.335 to 1.749.This leads to a challenge for the estimation of water and hydrocarbon saturation.Based on the analysis of Purcell equation and assumption that rock resistivity is determined by the parallel connection of numerous capillary resistances,a theoretical expression of cementation factor in terms of porosity and permeability is established.Then,cementation factor can be calculated if the parameters of porosity and permeability are determined.In the field application,porosity can be easily obtained by conventional logs.However,it is a tough challenge to estimate permeability due to the strong heterogeneity of low permeability reservoirs.Thus,the Schlumberger Doll Research(SDR)model derived from NMR logs has been proposed to estimate permeability.Based on the analysis of the theoretical expressions of cementation factor and SDR model,a novel cementation factor prediction model,which is relevant to porosity and logarithmic mean of NMR T2spectrum(T2lm),is derived.The advantage of this model is that all the input information can be acquired from NMR logs accurately.In order to confirm the credibility of the novel model,the resistivity and corresponding laboratory NMR measurements of 27 core samples are conducted.The credibility of the model is confirmed by comparing the predicted cementation factors with the core analyzed results.The absolute errors for all core samples are lower than 0.071.Once this model is extended to field application,the accuracy of water and hydrocarbon saturation estimation will be significantly improved.Liang Wang Zhiqiang Mao Yujiang Shi Qin'e Tao Yumei Cheng Yong Song 2014Journal of Earth Science2014,25,1:4

9Maize WI5 encodes an endo-1,4-β-xylanase required for secondary cell wall synthesis and water transport in xylem显示文摘Water transport from roots to leaves through xylem is important for plant growth and development.Defects in water transport can cause drought stress,even when there is adequate water in the soil.Here,we identi-fied the maize(Zea mays)wilty5(wi5)mutant,which ex-hibits marked dwarfing and leaf wilting throughout most of its life cycle under normal growth conditions.wilty5 seed-lings exhibited lower xylem conductivity and wilted more rapidly under drought,NaCl,and high temperature treat-ments than wild-type plants.Map-based cloning revealed that WI5 encodes an active endo-1,4-β-xylanase from gly-cosyl dehydration family 10,which mainly functions in degrading and reorganizing cell wall xylan.Reverse-transcription polymerase chain reaction andβ-glucuronidase assays revealed that WI5 is highly expressed in stems,especially in internodes undergoing secondary wall as-sembly.RNA sequencing suggested that WI5 plays a unique role in internode growth.Immunohistochemistry and electron microscopy confirmed that wi5 is defective in xylan deposition and secondary cell wall thickening.Lignin deposition and xylan content were markedly re-duced in wi5 compared to the wild-type plants.Our results suggest that WI5 functions in xylem cell wall thickening through its xylanase activity and thereby regulates xylem water transport,the drought stress response,and plant growth in maize.Xiaojiao Hu Yang Cui Xiaomin Lu Weibin Song Lei Lei Jinjie Zhu Jinsheng Lai Lizhu E Haiming Zhao 2020Journal of Integrative Plant Biology2020,62,10:3

13Paired eye-control study of unilateral opaque bubble layer in femtosecond laser assisted laser in situ keratomileusis显示文摘AIM: To investigate the predictive factors of the opaque bubble layer(OBL) compared to the fellow eye of same patients in FS200 femtosecond laser assisted laser in situ keratomileusis(FS-LASIK).METHODS: This study consisted of 60 consecutive patients(120 eyes) with unilateral OBL during FS-LASIK. Eyes were divided into OBL(the OBL eyes) and OBL-free groups(the fellow eyes) based on the occurrence of OBL. The preoperative demographic data, refraction, keratometry, corneal astigmatism, pachymetry, intraocular pressure and intraoperative data including the outlet location of gas diffusing canal were collected. Conditional logistic regression analysis was performed to find the associated factors with OBL in the two groups by determining odds ratios(OR) and 95%CI.RESULTS: The preoperative demographic data, mean spherical errors, mean K value, suction time, intraocular pressure and central cornea thickness were not significantly different between the two groups. The outlet location of gas diffusing canal(P<0.01, OR 7.16, 95%CI 2.53-20.32) and the corneal astigmatism(P=0.013, OR 0.13, 95%CI 0.03-0.65) were significantly associated with the incidence of OBL by multivariate logistic regression analysis. Visual acuity, efficacy, and safety were comparable between the two groups two months after surgery except for a slightly lower predictability value for the hard OBL eyes.CONCLUSION: The reduction of the incidence of OBL is obvious when the outlet of gas diffusing canal located at the posterior border of the corneoscleral limbus. This is probably consequent to more effectiveness of gas diffusing canal. Corneal astigmatism is also an independent protective factor for OBL formation.Cheng-Hua Wei Qiao-Yun Dai Li-Xin Mei Yao Ge Peng-Fei Zhang E Song 2019International Journal of Ophthalmology(English edition)2019,12,4:2
14Isolation and identifi cation of antimicrobial metabolites from sea anemone-derived fungus Emericella sp.SMA01显示文摘Marine symbiotic fungi represent an intriguing source of discovery of novel secondary metabolites with various biological activities.Sea anemones are benthic marine invertebrates,however,the cultivable symbiotic fungi residing in the sea anemones are paid few attentions compared to those derived from their cnidarian counterparts.Here we show the identification of antimicrobial secondary metabolites from the sea anemone-derived symbiotic fungi.Out offive isolated fungal strains,only the strain SMA01 showed strong antimicrobial activities,which was assigned into the genus Emericella based on the morphological characteristics and the ITS sequencing.Media swift from liquid fermentation to solid rice medium presented little influence on its antibacterial activity.A chemical investigation of the ethyl acetate extract of the Emericella sp.SMA01 led to discovery of the primary antibiotic metabolite phenazine-1-carboxylic acid.The IC_(50) values of the phenazine-1-carboxylic acid against Phytophthora capsici,Gibberella zeae,and Verticillium dahliae were determined to be 23.26-53.89μg/mL.To the best of our knowledge,this was the first report of Emericella sp.in sea anemones.The current study may benefit understanding of the defensive chemical interactions between the symbiotic fungi and their host sea anemones.Yang YUE Huahua YU Rongfeng LI Linfeng HU Song LIU Rong’e XING Pengcheng LI 2021Journal of Oceanology and Limnology2021,39,3:2

16Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows显示文摘Known as the‘third polar region’,the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there.Previous studies of birds,animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence.The adaptive processes during the initial phase of highland adaptation remain poorly understood.We studied a human commensal,the Eurasian Tree Sparrow,which has followed human agriculture to the Qinghai-Tibet Plateau.Despite strong phenotypic differentiation at multiple levels,in particular in muscle-related phenotypes,highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years.In a one-month acclimation experiment investigating phenotypic plasticity,we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes.Through population genetic analyses,we identified a signature of polygenic adaptation,whereby shifts in allele frequencies are spread across multiple loci,many of which are associated with muscle-related processes.Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution,shedding light on early stages of adaptive evolution to a novel environment.Yanhua Qu Chunhai Chen Ying Xiong Huishang She Yong E Zhang Yalin Cheng Shane DuBay Dongming Li Per G P Ericson Yan Hao Hongyuan Wang Hongfeng Zhao Gang Song Hailin Zhang Ting Yang Chi Zhang Liping Liang Tianyu Wu Jinyang Zhao Qiang Gao Weiwei Zhai Fumin Lei 2020National Science Review2020,7,1:2

18Effect of endothelial progenitor cells derived from human umbilical cord blood on oxygen-induced retinopathy in mice by intravitreal transplantation显示文摘·AIM: To investigate the effect of endothelial progenitor cells(EPCs) labeled by carboxy fluorescein diacetate succinimidyl ester(CFSE) on murine oxygen-induced retinopathy(OIR) by intravitreal transplantation.·METHODS: After isolated from human umbilical cord blood mononuclear cells, EPCs were cultivated and then labeled with CFSE in vitro. C57BL/6J mice were placed to75% hyperoxia chamber from P7 to P12 to establish OIR model. At P12, OIR mice were intravitreally injected with1 μL suspension contained 2×105EPCs(EPCs group) or isometric phosphate buffered saline(PBS group). The contralateral eye of each mice received no injection(OIR group). Evans blue angiography and frozen section were examined to track the labeled cells in OIR group at P15 and P19. Using retina paraffin sections and adenosinediphos phatase staining at P12 and P19, the effect of EPCs on OIR mice was evaluated quantitatively and qualitatively.· RESULTS: The retinas from EPCs group with less non-perfusion area and fewer peripheral tufts wereobserved at P19, comparing with that from PBS or OIR group. The retinopathy in EPCs group receded earlier with less non-ganglion cells and neovascular nuclei,together with relatively regular distribution. The counts of the neovascular nuclei at P19 were reduced by 44% or45%, compared with those of OIR group or PBS group respectively. Three days after EPCs injection, a large number of EPCs appeared in the vitreous cavity and adhered to the retinal surface. While at one week, the cells gathered between the internal plexiform layer and the inner limiting membrane, and some EPCs appeared in retinal vessels.·CONCLUSION: EPCs transplantation can participate in the reparative procedure of the neovascularization in OIR.Dan Wang Bo Zhang Hui Shi Wei Yang Ming-Chao Bi Xiang-Fu Song Chen Zhang Jian-Hui Cheng Ji-Long Hao E Song 2016International Journal of Ophthalmology(English edition)2016,9,11:2

20QoS prediction algorithm used in location-aware hybrid Web service显示文摘Quality-of-Service(QoS) describes the non-functional characteristics of Web services. As such, the QoS is a critical parameter in service selection, composition and fault tolerance, and must be accurately determined by some type of QoS prediction method. However, with the dramatic increase in the number of Web services, the prediction failure caused by data sparseness has become a critical challenge. A new ‘hybrid user-location-aware prediction based on weighted Adamic-Adar(WAA)'(HUWAA) was proposed. The implicit neighbor search was optimized by incorporating location factors. Meanwhile, the ability of the improved algorithms to solve the data sparsity problem was validated in experiments on public real world datasets. The new algorithm outperforms the existing of item-based pearson correlation coefficient(IPCC), user-based pearson correlation coefficient(UPCC) and Web service recommender system(WSRec) algorithms.E Haihong Tong Junjie Song Meina Song Junde 2015The Journal of China Universities of Posts and Telecommunications2015,22,1:2
