1The Chrysanthemum nankingense Genome Provides Insights into the Evolution and Diversification of Chrysanthemum Flowers and Medicinal Traits显示文摘The Asteraceae (Compositae),a large plant family of approximately 24 000-35 000 species,accounts for^10% of all angiosperm species and contributes a lot to plant diversity.The most representative members of the Asteraceae are the economically important chrysanthemums (Chrysanthemum L.)that diversified through reticulate evolution.Biodiversity is typically created by multiple evolutionary mechanisms such as wholegenome duplication 0NGD)or polyploidization and locally repetitive genome expansion.However,the lack of genomic data from chrysanthemum species has prevented an in-depth analysis of the evolutionary mechanisms involved in their diversification.Here,we used Oxford Nanopore long-read technologyto sequence the diploid Chrysanthemum nankingense genome,which represents one of the progenitor genomes of domesticated chrysanthemums.Our analysis revealed that the evolution of the C.nankingense genome was driven by bursts of repetitive element expansion and WGD events including a recentWGD that distinguishes chrysanthemum from sunflower,which diverged from chrysanthemum approximately 38.8 million years ago.Variations of ornamental and medicinal traits in chrysanthemums are linked to the expansion of candidate gene families by duplication events including paralogous gene duplication.Collectively,our study of the assembled reference genome offers new knowledge and resources to dissect the history and pattern of evolution and diversification of chrysanthemum plants,and also to accelerate their breeding and improvement.Chi Song Yifei Liu Aiping Song Gangqiang Dong Hongbo Zhao Wei Sun Shyam Ramakrishnan Ying Wang Shuaibin Wang Tingzhao Li Yan Niu Jiafu Jiang Bin Dong Ye Xia Sumei Chen Zhigang Hu Fadi Chen Shilin Chen 2018Molecular Plant2018,11,12:24

3Current achievements and future prospects in the genetic breeding of chrysanthemum:a review显示文摘Chrysanthemum(Chrysanthemum morifolium Ramat.)is a leading flower with applied value worldwide.Developing new chrysanthemum cultivars with novel characteristics such as new flower colors and shapes,plant architectures,flowering times,postharvest quality,and biotic and abiotic stress tolerance in a time-and cost-efficient manner is the ultimate goal for breeders.Various breeding strategies have been employed to improve the aforementioned traits,ranging from conventional techniques,including crossbreeding and mutation breeding,to a series of molecular breeding methods,including transgenic technology,genome editing,and marker-assisted selection(MAS).In addition,the recent extensive advances in high-throughput technologies,especially genomics,transcriptomics,proteomics,metabolomics,and microbiomics,which are collectively referred to as omics platforms,have led to the collection of substantial amounts of data.Integration of these omics data with phenotypic information will enable the identification of genes/pathways responsible for important traits.Several attempts have been made to use emerging molecular and omics methods with the aim of accelerating the breeding of chrysanthemum.However,applying the findings of such studies to practical chrysanthemum breeding remains a considerable challenge,primarily due to the high heterozygosity and polyploidy of the species.This review summarizes the recent achievements in conventional and modern molecular breeding methods and emerging omics technologies and discusses their future applications for improving the agronomic and horticultural characteristics of chrysanthemum.Jiangshuo Su Jiafu Jiang Fei Zhang Ye Liu Lian Ding Sumei Chen Fadi Chen 2019Horticulture Research2019,6,1:13
4Genome-wide association study identifies favorable SNP alleles and candidate genes for waterlogging tolerance in chrysanthemums显示文摘Chrysanthemums are sensitive to waterlogging stress,and the development of screening methods for tolerant germplasms or genes and the breeding of tolerant new varieties are of great importance in chrysanthemum breeding.To understand the genetic basis of waterlogging tolerance(WT)in chrysanthemums,we performed a genome-wide association study(GWAS)using 92,811 single nucleotide polymorphisms(SNPs)in a panel of 88 chrysanthemum accessions,including 64 spray cut and 24 disbud chrysanthemums.The results showed that the average MFVW(membership function value of waterlogging)of the disbud type(0.65)was significantly higher than that of the spray type(0.55)at P<0.05,and the MFVW of the Asian accessions(0.65)was significantly higher than that of the European accessions(0.48)at P<0.01.The GWAS performed using the general linear model(GLM)and mixed linear model(MLM)identified 137 and 14 SNP loci related to WT,respectively,and 11 associations were commonly predicted.By calculating the phenotypic effect values for 11 common SNP loci,six highly favorable SNP alleles that explained 12.85—21.85%of the phenotypic variations were identified.Furthermore,the dosage-pyramiding effects of the favorable alleles and the significant linear correlations between the numbers of highly favorable alleles and phenotypic values were identified(r2=0.45;P<0.01).A major SNP locus(Marker6619-75)was converted into a derived cleaved amplified polymorphic sequence(dCAPS)marker that cosegregated with WT with an average efficiency of 78.9%.Finally,four putative candidate genes in the WT were identified via quantitative real-time PCR(qRT-PCR).The results presented in this study provide insights for further research on WT mechanisms and the application of molecular marker-assisted selection(MAS)in chrysanthemum WT breeding programs.Jiangshuo Su Fei Zhang Xinran Chong Aiping Song Zhiyong Guan Weimin Fang Fadi Chen 2019Horticulture Research2019,6,1:9
5Raman tensor of AlN bulk single crystal显示文摘The angle dependence of optical phonon modes of an AlN bulk single crystal from the m-plane(1100) and c-plane(0001) surfaces, respectively, is investigated by polarized Raman spectroscopy in a backscattering configuration at room temperature. Corresponding Raman selection rules are derived according to measured scattering geometries to illustrate the angle dependence. The angle-dependent intensities of phonon modes are discussed and compared to theoretical scattering intensities, yielding the Raman tensor elements of A1(TO), E22, E1(TO), and A1(LO) phonon modes and the relative phase difference between the two complex elements of A1(TO). Furthermore, the Raman tensor of wurtzite AlN is compared with that of wurtzite ZnO reported in previous work, revealing the intrinsic differences of lattice vibration dynamics between AlN and ZnO.Wei Zheng Ruisheng Zheng Feng Huang Honglei Wu Fadi Li 2015Photonics Research2015,3,2:9
6Radiation exposure and reduction in the operating room: Perspectives and future directions in spine surgery显示文摘Intraoperative imaging is vital for accurate placement of instrumentation in spine surgery. However, the use of biplanar fluoroscopy and other intraoperative imaging modalities is associated with the risk of significant radiation exposure in the patient, surgeon, and surgical staff. Radiation exposure in the form of ionizing radiation can lead to cellular damage via the induction of DNA lesions and the production of reactive oxygen species. These effects often result in cell death or genomic instability, leading to various radiation-associated pathologies including an increased risk of malignancy. In attempts to reduce radiation-associated health risks, radiation safety has become an important topic in the medical field. All practitioners, regardless of practice setting, can practice radiation safety techniques including shielding and distance to reduce radiation exposure. Additionally, optimization of fluoroscopic settings and techniques can be used as an effective method of radiation dose reduction. New imaging modalities and spinal navigation systems have also been developed in an effort to replace conventional fluoroscopy and reduce radiation doses. These modalities include Isocentric Three-Dimensional C-Arms, O-Arms, and intraoperative magnetic resonance imaging. While this influx of new technology has advanced radiation safety within the field of spine surgery, more work is still required to overcome specific limitations involving increased costs and inadequate training.Ankur S Narain Fady Y Hijji Kelly H Yom Krishna T Kudaravalli Brittany E Haws Kern Singh 2017World Journal of Orthopedics2017,8,7:9
7Cytological and Molecular Characteristics of Pollen Abortion in Lily with Dysplastic Tapetum显示文摘Lily was grown worldwide as a fresh cutting flower because of its colorful petals, but its anther contained a large number of pollen grains that cause serious pollen contamination, however, pollen abortion can effectively reduce the level of pollen pollution. Our analysis aims to use cytological observation to detect the critical stage when pollen abortion occurs and to provide comprehensive gene expression information at the transcriptional level. The result showed that pollen abortion in ‘Little Kiss’ began at the mononuclear stage and the callose that covers the microspores failed to degenerate when young pollens were released from the tetrads. In addition, compared with the normally developed one,the tapetum of ‘Little Kiss’ degraded in advance while the degradation of callose was delayed. Furthermore, 103 differentially expressed genes(DEGs) related to the advance degeneration of tapetum cells and callose were found in the expression levels, including 22 transcription factors(TFs). In particular, two β-glucanase genes(endo-1,3(4)-β-glucanase, exo-β-glucanase) responsible for callose degeneration were significantly down-regulated. These results suggested that pollen abortion may occur at mononuclear stage and that early degeneration of tapetum cells resulted in a significant down-regulation of β-glucanase genes. As a result, the callose to cover microspores impedes the formation of pollen walls, which may possibly lead to pollen abortion.Xueqian Wang Ze Wu Lanqing Wang Meijiao Wu Dehua Zhang Weimin Fang Fadi Chen Nianjun Teng 2019Horticultural Plant Journal2019,5,6:9
8Comparative Analysis of Leaf Trichomes, Epidermal Wax And Defense Enzymes Activities in Response to Puccinia horiana in Chrysanthemum and Ajania Species显示文摘White rust caused by Puccinia horiana is a destructive disease of chrysanthemum plants.To better understand the resistance mechanisms of composite species to this disease,the leaf cuticular traits,antioxidant and defensive enzymes activities of immune(Chrysanthemum makinoi var.wakasaense)and highly susceptible(Ajania shiwogiku var.kinokuniense)species were compared.Trichome density of two species was markedly different,negatively associated with plant resistance to P.horiana.Total wax load in C.makinoi var.wakasaense was two times more than that in A.shiwogiku var.kinokuniense.The wax composition in immune one was abundant in esters and primary alcohols.Superoxide dismutase(SOD,EC 1.15.1.1),peroxidase(POD,EC 1.11.1.7),polyphenoloxidase(PPO,EC 1.14.18.1 or EC 1.10.3.2)and phenylalanine ammonia lyase(PAL,EC 4.3.1.5)activitieswere investigated.In C.makinoi var.wakasaense,the activity of SOD and POD increased rapidly after inoculation,whichmight be non-host induced reactive oxygen species(ROS)activated antioxidant enzymes,however SOD and POD remained a low and steady level in the highly susceptible one after inoculation.Quick increase in PPO activities after inoculation was observed in both species,however it remained higher in C.makinoi var.wakasaense at the late period of inoculation.PAL in C.makinoi var.wakasaense was induced after pathogen inoculation,but not in A.shiwogiku var.kinokuniense,suggesting that these two enzymes might contribute to the resistance to P.horiana.Yinjie Wang Jun Zeng Xiaolong Xia Yang Xu Jing Sun Jing Gu Hainan Sun Haini Lei Fadi Chen Jiafu Jiang Weiming Fang Sumei Chen 2020Horticultural Plant Journal2020,6,3:8
9Liver transplantation for hepatocellular carcinoma:an update显示文摘BACKGROUND: Hepatocellular carcinoma (HCC) is a heterogeneous malignancy with multiple etiologies, high incidence, and high mortality. The standard surgical management for patients with HCC consists of locoregional ablation, surgical resection, or liver transplantation, depending on the background state of the liver. Eighty percent of patients initially presenting with HCC are unresectable, either due to the extent of tumor or the level of underlying hepatic dysfunction. While in patients with no evidence of cirrhosis and good hepatic function resection has been the surgical treatment of choice, it is contraindicated in patients with moderate to severe cirrhosis. Liver transplantation is the optimal surgical treatment. DATA SOURCES: PubMed search of recent articles (from January 2000 to March 2011) was performed looking for relevant articles about hepatocellular carcinoma and its treatment. Additional articles were identified by evaluating references from selected articles. RESULTS: Here we review criteria for transplantation, the types, indications, and role of locoregional therapy in treating the cancer and in downstaging for possible later transplantation. We also summarize the contribution of immunosuppression and adjuvant chemotherapy in the management and prevention of HCC recurrence. Finally we discuss recent advances in imaging, tumor biology, and genomics as we delineate the remaining challenges for the diagnosis and treatment of this disease. CONCLUSIONS: Much can be improved in the diagnosis and treatment of HCC. A great challenge will be to improve patient selection to criteria based on tumor biology. Another will be to incorporate systemic agents post-operatively in patients at high risk for recurrence, paying close attention to efficacy and safety. The future direction of the effort in treating HCC will be to stimulate prospective trials, develop molecular imaging of lymphovascular invasion, to improve recipient selection, and to investigate biomarkers of tumor biology.Ali Zarrinpar Fady Kaldas Ronald W Busuttil 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:8
10Optimum chemotherapy in the management of metastatic pancreatic cancer显示文摘Pancreatic cancer is one of the most devastating solid tumors,and it remains one of the most difficult to treat.The treatment of metastatic pancreatic cancer(MPC)is systemic,based on chemotherapy or best supportive care,depending on the performance status of the patient.Two chemotherapeutical regimens have produced substantial benefits in the treatment of MPC:gemcitabine in 1997;and FOLFIRIONOX in 2011.FOLFIRINOX improved the natural history of MPC,with overall survival(OS)of 11.1 mo.Nab-paclitaxel associated with gemcitabine is a newly approved regimen for MPC,with a median OS of 8.6 mo.Despite multiple trials,this targeted therapy was not efficient in the treatment of MPC.Many new molecules targeting the proliferation and survival pathways,immune response,oncofetal signaling and the epigenetic changes are currently undergoing phaseⅠandⅡtrials for the treatment of MPC,with many promising results.Marwan Ghosn Hampig Raphael Kourie Fadi El Karak Colette Hanna Joelle Antoun Dolly Nasr 2014World Journal of Gastroenterology2014,20,9:7
11Functional analysis of alternative splicing of the FLOWERING LOCUS T orthologous gene in Chrysanthemum morifolium显示文摘As the junction of floral development pathways,the FLOWERING LOCUS T(FT)protein called‘florigen’plays an important role in the process of plant flowering through signal integration.We isolated four transcripts encoding different isoforms of a FT orthologous gene CmFTL1,from Chrysanthemum morifolium cultivar‘Jimba’.Sequence alignments suggested that the four transcripts are related to the intron 1.Expression analysis showed that four alternative splicing(AS)forms of CmFTL1 varied depending on the developmental stage of the flower.The functional complement experiment using an Arabidopsis mutant ft-10 revealed that the archetypal and AS forms of CmFTL1 had the function of complementing late flower phenotype in different levels.In addition,transgenic confirmation at transcript level showed CmFTL1 and CmFTL1ast coexist in the same tissue type at the same developmental stage,indicating a post-transcriptional modification of CmFTL1 in Arabidopsis.Moreover,ectopic expression of different AS forms in chrysanthemum resulted in the development of multiple altered phenotypes,varying degrees of early flowering.We found that an alternative splicing form(CmFTL1-astE134)without the exon 2 lacked the ability causing the earlier flower phenotype.The evidence in this study indicates that complex alternative processing of CmFTL1 transcripts in C.morifolium may be associated with flowering regulation and hold some potential for biotechnical engineering to create early-flowering phenotypes in ornamental cultivars.Yachao Mao Jing Sun Peipei Cao Rong Zhang Qike Fu Sumei Chen Fadi Chen Jiafu Jiang 2016Horticulture Research2016,3,1:7
12CmFTL2 is involved in the photoperiod- and sucrose-mediated control of flowering time in chrysanthemum显示文摘The chrysanthemum genome harbors three FT-like genes:CmFTL1 and CmFTL3 are thought to act as regulators of floral induction under long-day(LD)and short-day(SD)conditions,respectively,whereas the function of CmFTL2 is currently unclear.The objective of the present research was to explore the function of CmFTL2 in the determination of flowering time of the photo-insensitive chrysanthemum cultivar‘Floral Yuuka’,both in response to variation in the photoperiod and to the exogenous provision of sucrose.Spraying leaves of‘Floral Yuuka’plants with 50 mM sucrose accelerated flowering and increased the level of CmFTL2 transcription in the leaf more strongly than either CmFTL1 or FTL3 under both long and SD conditions.Transcription profiling indicated that all three CmFTL genes were upregulated during floral induction.The relationship of the CmFTL2 sequence with that of other members of the PEBP family suggested that its product contributes to the florigen rather than to the anti-florigen complex.The heterologous expression of CmFTL2 in the Arabidopsis thaliana ft-10 mutant rescued the mutant phenotype,showing that CmFTL2 could compensate for the absence of FT.These results suggest that CmFTL2 acts as a regulator of floral transition and responds to both the photoperiod and sucrose.Jing Sun Heng Wang Liping Ren Sumei Chen Fadi Chen Jiafu Jiang 2017Horticulture Research2017,4,1:7
13Overexpression of CmMYB15 provides chrysanthemum resistance to aphids by regulating the biosynthesis of lignin显示文摘MYB transcription factors are widely involved in the development of and physiological processes in plants.Here,we isolated the chrysanthemum R2R3-MYB family transcription factor CmMYB15,a homologous gene of AtMYB15.It was demonstrated that CmMYB15 expression was induced by aphids and that CmMYB15 could bind to AC elements,which usually exist in the promoter of lignin biosynthesis genes.Overexpression of CmMYB15 in chrysanthemum enhanced the resistance of aphids.Additionally,the content of lignin and the expression of several lignin biosynthesis genes increased.In summary,the results indicate that CmMYB15 regulates lignin biosynthesis genes that enhance the resistance of chrysanthemum to aphids.Cong An Liping Sheng Xinping Du Yinjie Wang Yi Zhang Aiping Song Jiafu Jiang Zhiyong Guan Weimin Fang Fadi Chen Sumei Chen 2019Horticulture Research2019,6,1:6
14重新审视加工贸易在我国经济增长中的作用显示文摘随着我国经济结构的优化和比较优势的逐步转变,许多学者开始质疑加工贸易在我国经济中的积极作用。文章运用可变参数模型、协整分析和Granger因果检验考察了加工贸易在我国经济中的动态影响,加工贸易顺差与我国GDP之间的关系。结果显示加工贸易对我国经济的推动作用不断增强;加工贸易顺差与我国GDP之间存在着稳定的均衡关系,加工贸易顺差每增长1%将会拉动GDP增长0.43%,而且二者互为因果关系,相互推动。因此,加工贸易在我国经济中的积极作用仍然不容忽视,我国应该继续发展加工贸易。周月波 Fadi Alammar 2007北方经贸2007,,2:6
15Pulmonary complications after spine surgery显示文摘Spine surgery is one of the fastest growing branches of orthopedic surgery. Patients often present with a relatively high acuity and, depending on surgical approach, morbidity and mortality can be comparatively high. Among the most prevalent and most frequently fatalitybound perioperative complications are those affecting the pulmonary system; evidence of clinical or subclinical lung injury triggered by spine surgical procedures is emerging. Increasing burden of comorbidity among the patient population further increases the likelihood of adverse outcome. This review is intended to give an overview over some of the most important causes of pulmonary complications after spine surgery, their pathophysiology and possible ways to reduce harm associated with those conditions. We discuss factors surrounding surgical trauma, timing of surgery, bone marrow and debris embolization, transfusion associated lung injury, and ventilator associated lung injury.Ottokar Stundner Fadi Taher Abhijit Pawar Stavros G Memtsoudis 2012World Journal of Orthopedics2012,3,10:5
16Regulation of flowering time in chrysanthemum by the R2R3 MYB transcription factor CmMYB2 is associated with changes in gibberellin metabolism显示文摘The switch from vegetative growth to reproductive growth is a key event in the development of a plant.Here,the product of the chrysanthemum gene CmMYB2,an R2R3 MYB transcription factor that is localized in the nucleus,was shown to be a component of the switching mechanism.Plants engineered to overexpress CmMYB2 flowered earlier than did wild-type plants,while those in which CmMYB2 was suppressed flowered later.In both the overexpression and RNAi knockdown plants,a number of genes encoding proteins involved in gibberellin synthesis or signaling,as well as in the response to photoperiod,were transcribed at a level that differed from that in the wild type.Both yeast two-hybrid and bimolecular fluorescence complementation assays revealed that CmMYB2 interacts with CmBBX24,a zinc-finger transcription factor known to regulate flowering by its influence on gibberellin synthesis.Lu Zhu Yunxiao Guan Yanan Liu Zhaohe Zhang Muhammad Abuzar Jaffar Aiping Song Sumei Chen Jiafu Jiang Fadi Chen 2020Horticulture Research2020,7,1:5
17Microstructure and texture evolution of AZ31 Mg alloy after uniaxial compression and annealing显示文摘The effect of initial texture on the microstructure and texture evolution of as extruded AZ31 alloy after hot uniaxial compression at 430°C and subsequent annealing at 450°C for 72h has been investigated using electron backscatter diffraction.Samples were machined from the extruded block in such orientations that the compression axis,CD,was parallel(CD0ED)or perpendicular(CD90ED)to the initial extrusion direction,ED,respectively.Results show that the deformation microstructure for both samples was characterized by equiaxed grains that resulted from dynamic recrystallization.Annealing at 450°C for 72 h led to the increase of grains size to 28 and 25μm for CD0ED and CD90ED samples,respectively.A random deformation texture was developed in CD0ED sample while the deformation of CD90ED developed typical(0002)basal texture.The deformation textures of both samples were retained after subsequent annealing at 450°C for 72 h.The flow behavior was affected by the initial texture.The CD0ED sample showed the highest work hardening.These evolutions were explained in term of the activation and suppression of basal,non-basal slip and mechanical twinning.©2018 Published by Elsevier B.V.on behalf of Chongqing University.This is an open access article under the CC BY-NC-ND license.Fadi Abouhilou Abdelkader Hanna Hiba Azzeddine Djamel Bradai 2019Journal of Magnesium and Alloys2019,7,1:5
18Lubiprostone used with polyethylene glycol in diabetic patients enhances colonoscopy preparation quality显示文摘AIM: To assess the additive effect of lubiprostone on the quality of colon preparation in diabetics given single-dosed polyethylene glycol electrolyte(PEG)for colonoscopy.METHODS:This was an investigator-initiated,singlecenter,single-blinded prospective trial comparing the efficacy of L+PEG to PEG alone on colon preparation quality in diabetics undergoing screening colonoscopy.The study was approved by our institution’s IRB.The PEG was given as a single-dose to address patientcompliance concerns voiced by our IRB with splitdosing.All patients received only clear liquids the day prior to colonoscopy.Experimental group(Grp L)received PEG+1 dose L 2 h prior to and 2 h after PEG completion.Control group(Grp C)received only PEG the evening prior to the colonoscopy.Patients were randomly assigned to one of the 2 groups.The endoscopist was blinded to which colon prep was given and all colonoscopies were complete.Upon colonoscopy completion,the endoscopist rated the colon prep-quality by a validated 5-point Likert scale(1-excellent to 5-inadequate).RESULTS:Sixty patients were enrolled in the study;30 Grp L and 30 Grp C.Overall,patients were excluded due to study non-completion in 12(41%)Grp L and 5(17%) Grp C,P=0.04.Average colon preparation score Grp L =2.47 and Grp C=3.00,P=0.09.Although this was not statistically significant,there was a trend towards improved colon prep in Grp L.Statistical significance may have been achieved if completion rates had been similar between both study groups.CONCLUSION:Use of 2-L capsules with PEG resulted in a trend towards improved colon prep over PEG alone in diabetic patients when given as a single-dose regimen.Erika Grigg Moonkyung C Schubert Joshua Hall Fadi Rahhal Dimple Raina Subbaramiah Sridhar Sherman M Chamberlain 2010World Journal of Gastrointestinal Endoscopy2010,2,7:5
