| 2 | Sequencing of Cultivated Peanut, Arachis hypogaea, Yields Insights into Genome Evolution and Oil Improvement显示文摘Cultivated peanut (Arachis hypogaea) is an allotetraploid crop planted in Asia, Africa, and America for edible oil and protein. To explore the origins and consequences of tetraploidy, we sequenced the allotetraploid A. hypogaea genome and compared it with the related diploid Arachis duranensis and Arachis ipaensis genomes. We annotated 39 888 A-subgenome genes and 41 526 B-subgenome genes in allotetraploid peanut. The A. hypogaea subgenomes have evolved asymmetrically, with the B subgenome resembling the ancestral state and the A subgenome undergoing more gene disruption, loss, conversion, and transposable element proliferation, and having reduced gene expression during seed development despite lacking genome-wide expression dominance. Genomic and transcriptomic analyses identified more than 2 500 oil metabolism-related genes and revealed that most of them show altered expression early in seed development while their expression ceases during desiccation, presenting a comprehensive map of peanut lipid biosynthesis. The availability of these genomic resources will facilitate a better understanding of the complex genome architecture, agronomically and economically important genes, and genetic improvement of peanut. | Xiaoping Chen Qing Lu Hao Liu Jianan Zhang Yanbin Hong Haofa Lan Haifen Li Jinpeng Wang Haiyan Liu Shaoxiong Li Manish K.Pandey Zhikang Zhang Guiyuan Zhou Jigao Yu Guoqiang Zhang Jiaqing Yuan Xingyu Li Shijie Wen Fanbo Meng Shanlin Yu Xiyin Wang Kadambot H.M.Siddique Zhong-Jian Liu Andrew H.Paterson Rajeev K.Varshney Xuanqiang Liang | 2019 | Molecular Plant2019,12,7: | 23 |

| 4 | 新型PEO/纳米结构ZrO_2镁合金涂层的抗菌活性及腐蚀行为(英文)显示文摘为了增强镁合金的耐腐蚀性和抗菌活性,先采用等离子体电解氧化(PEO)在镁合金上制备一层结合层,再用空气等离子喷涂(APS)制备纳米结构ZrO_2表面涂层。采用电化学试验研究涂层样品的腐蚀行为,采用琼脂扩散法对其进行大肠杆菌病原菌抑菌活性评价,并与无涂层样品进行对比。与PEO涂层和无涂层镁合金相比,PEO/纳米ZrO_2涂层样品的腐蚀电流密度最低,电荷传递阻力最高,相位角和阻抗模量最高。PEO结合涂层被纳米ZrO_2表面涂层完全密封,能够显著延缓侵蚀性离子向镁合金表面迁移,显著提高镁合金在模拟体液(SBF)中的耐蚀性。此外,PEO/纳米ZrO_2涂层的抗菌活性也高于PEO涂层和无涂层镁合金,这是由于ZrO_2纳米颗粒通过作用于细胞膜而降低了大肠杆菌的生长速率。 | Mohammadreza DAROONPARVAR Muhamad Azizi MAT YAJID Rajeev KUMAR GUPTA Noordin MOHD YUSOF Hamid Reza BAKHSHESHI-RAD Hamidreza GHANDVAR Ehsan GHASEMI | 2018 | Transactions of Nonferrous Metals Society of China2018,28,8: | 10 |
| 5 | Pediatric hepatocellular carcinoma显示文摘Pediatric hepatocellular carcinoma (HCC) is the second common malignant liver tumor in children after hepato-blastoma. It differs from the adult HCC in the etiological predisposition, biological behavior and lower frequency of cirrhosis. Perinatally acquired hepatitis-B virus, hepa-torenal tyrosinemia, progressive familial intrahepatic cho-lestasis, glycogen storage disease, Alagille's syndrome and congenital portosystemic shunts are important predis-posing factors. Majority of children (87%) are older than 5 years of age. Following mass immunization against hepatitis-B, there has been a drastic fall in the incidence of new cases of pediatric HCC in the Asia-Pacific region. Management is targeted on complete surgical removal either by resection or liver transplantation. There is a trend towards improving survival of children transplanted for HCC beyond Milan criteria. Chemotherapeutic regi-mens do not offer good results but may be helpful for down-staging of advanced HCC. Surveillance of children with chronic liver diseases with ultrasound and alpha-fetoprotein may be helpful in timely detection, intervention and overall improvement in outcome of HCC. | Rajeev Khanna Sanjeev Kumar Verma | 2018 | World Journal of Gastroenterology2018,24,35: | 9 |

| 8 | Smart breeding driven by big data, artificial intelligence, and integrated genomic-enviromic prediction显示文摘The first paradigm of plant breeding involves direct selection-based phenotypic observation,followed by predictive breeding using statistical models for quantitative traits constructed based on genetic experimental design and,more recently,by incorporation of molecular marker genotypes.However,plant performance or phenotype(P)is determined by the combined effects of genotype(G),envirotype(E),and genotype by environment interaction(GEI).Phenotypes can be predicted more precisely by training a model using data collected from multiple sources,including spatiotemporal omics(genomics,phenomics,and enviromics across time and space).Integration of 3D information profiles(G-P-E),each with multidimensionality,provides predictive breeding with both tremendous opportunities and great challenges.Here,we first review innovative technologies for predictive breeding.We then evaluate multidimensional information profiles that can be integrated with a predictive breeding strategy,particularly envirotypic data,which have largely been neglected in data collection and are nearly untouched in model construction.We propose a smart breeding scheme,integrated genomic-enviromic prediction(iGEP),as an extension of genomic prediction,using integrated multiomics information,big data technology,and artificial intelligence(mainly focused on machine and deep learning).We discuss how to implement iGEP,including spatiotemporal models,environmental indices,factorial and spatiotemporal structure of plant breeding data,and cross-species prediction.A strategy is then proposed for prediction-based crop redesign at both the macro(individual,population,and species)and micro(gene,metabolism,and network)scales.Finally,we provide perspectives on translating smart breeding into genetic gain through integrative breeding platforms and open-source breeding initiatives.We call for coordinated efforts in smart breeding through iGEP,institutional partnerships,and innovative technological support. | Yunbi Xu Xingping Zhang Huihui Li Hongjian Zheng Jianan Zhang Michael S.Olsen Rajeev K.Varshney Boddupalli M.Prasanna Qian Qian | 2022 | Molecular Plant2022,15,11: | 7 |
| 9 | Approximation of surface-groundwater interaction mediated by vertical streambank in sloping terrains显示文摘New analytical solutions are derived to estimate the interaction of surface and groundwater in a stream-aquifer system.The analytical model consists of an unconfined sloping aquifer of semi-infinite extant,interacting with a stream of varying water level in the presence of a thin vertical sedimentary layer of lesser hydraulic conductivity.Flow of subsurface seepage is characterized by a nonlinear Boussinesq equation subjected to mixed boundary conditions,including a nonlinear Cauchy boundary condition to approximate the flow through the sedimentary layer.Closed form analytical expressions for water head,discharge rate and volumetric exchange are derived by solving the linearized Boussinesq equation using Laplace transform technique.Asymptotic cases such as zero slope,absence of vertical clogging layer and abrupt change in stream-stage can be derived from the main results by taming one or more parameters.Analytical solutions of the linearized Boussinesq equation are compared with numerical solution of corresponding nonlinear equation to assess the validity of the linearization.Advantages of using a nonlinear Robin boundary condition,and combined effects of aquifer parameters on the bank storage characteristic of the aquifer are illustrated with a numerical example. | Rajeev K.Bansal | 2017 | Journal of Ocean Engineering and Science2017,2,1: | 6 |

| 12 | Colonoscopy surveillance for high risk polyps does not always prevent colorectal cancer显示文摘AIM To determine the frequency and risk factors for colorectal cancer(CRC) development among individuals with resected advanced adenoma(AA)/traditional serrated adenoma(TSA)/advanced sessile serrated adenoma(ASSA). METHODS Data was collected from medical records of 14663 subjects found to have AA, TSA, or ASSA at screening or surveillance colonoscopy. Patients with inflammatory bowel disease or known genetic predisposition for CRC were excluded from the study. Factors associated with CRC developing after endoscopic management of high risk polyps were calculated in 4610 such patients who had at least one surveillance colonoscopy within 10 years following the original polypectomy of the incident advanced polyp. RESULTS84/4610(1.8%) patients developed CRC at the polypectomy site within a median of 4.2 years(mean 4.89 years), and 1.2%(54/4610) developed CRC in a region distinct from the AA/TSA/ASSA resection site within a median of 5.1 years(mean 6.67 years). Approximately, 30%(25/84) of patients who developed CRC at the AA/TSA/ASSA site and 27.8%(15/54) of patients who developed CRC at another site had colonoscopy at recommended surveillance intervals. Increasing age; polyp size; male sex; right-sided location; high degree of dysplasia; higher number of polyps resected; and piecemeal removal were associated with an increased risk for CRC developmentat the same site as the index polyp. Increasing age; right-sided location; higher number of polyps resected and sessile endoscopic appearance of the index AA/TSA/ASSA were significantly associated with an increased risk for CRC development at a different site. CONCLUSION Recognition that CRC may develop following AA/TSA/ASSA removal is one step toward improving our practice efficiency and preventing a portion of CRC related morbidity and mortality. | Mohamad A Mouchli Lidia Ouk Marianne R Scheitel Alisha P Chaudhry Donna Felmlee-Devine Diane E Grill Shahrooz Rashtak Panwen Wang Junwen Wang Rajeev Chaudhry Thomas C Smyrk Ann L Oberg Brooke R Druliner Lisa A Boardman | 2018 | World Journal of Gastroenterology2018,24,8: | 5 |

| 15 | Sarcopenia in Chronic Liver Disease:A Metabolic Perspective显示文摘Sarcopenia,a condition of low muscle mass,quality,and strength,is commonly found in patients with chronic liver disease(CLD)and is associated with adverse clinical out-comes including reduction in quality of life,increased mor-tality,and complications.A major contributor to sarcopenia in CLD is the imbalance in muscle protein turnover wherein changes in various metabolic factors such as hyperammone-mia,amino acid deprivation,hormonal imbalance,gut dys-biosis,insulin resistance,chronic inflammation,etc.have important roles.In particular,hyperammonemia is a key mediator of the liver-gut axis and is known to contribute to sarcopenia by various mechanisms including increased ex-pression of myostatin,increased phosphorylation of eukary-otic initiation factor 2a,cataplerosis ofα-ketoglutarate,mi-tochondrial dysfunction,increased reactive oxygen species that decrease protein synthesis and increased autophagy-mediated proteolysis.Skeletal muscle is a major organ of insulin-induced glucose metabolism,and sarcopenia is closely linked to insulin resistance and metabolic syndrome.Patients with liver cirrhosis are in a hypermetabolic state that is associated with catabolism and depletion of amino acids,particularly branched-chain amino acids.Sarcopenia can have significant implications for nonalcoholic fatty liver disease,the most common form of CLD worldwide,because of the close link between metabolic syndrome and sarcope-nia.This review discusses the potential metabolic derange-ment as a cause or effect of sarcopenia in CLD,as well as interorgan crosstalk,which that might help identifying a novel therapeutic strategies. | Ramesh Kumar Sabbu Surya Prakash Rajeev Nayan Priyadarshi Utpal Anand | 2022 | Journal of Clinical and Translational Hepatology2022,10,6: | 4 |
| 16 | Identification of ExpIdentification of Expressed Resistance Gene Analogs from Peanut (Arachis hypogaea L.) Expressed Sequence Tags显示文摘Low genetic diversity makes peanut (Arachis hypogaea L.) very vulnerable to plant pathogens, causing severe yield loss and reduced seed quality. Several hundred partial genomic DNA sequences as nucleotide-binding-site leucine-rich repeat (NBS-LRR) resistance genes (R) have been identified, but a small portion with expressed transcripts has been found. We aimed to identify resistance gene analogs (RGAs) from peanut expressed sequence tags (ESTs) and to develop polymorphic markers. The protein sequences of 54 known R genes were used to identify homologs from peanut ESTs from public databases. A total of 1,053 ESTs corresponding to six different classes of known R genes were recovered, and assembled 156 contigs and 229 singletons as peanut-expressed RGAs. There were 69 that encoded for NBS-LRR proteins, 191 that encoded for protein kinases, 82 that encoded for LRR-PK/transmembrane proteins, 28 that encoded for Toxin reductases, 11 that encoded for LRR-domain containing proteins and four that encoded for TM-domain containing proteins. Twenty-eight simple sequence repeats (SSRs) were identified from 25 peanut expressed RGAs. One SSR polymorphic marker (RGA121) was identified. Two polymerase chain reaction-based markers (Ahsw-1 and Ahsw-2) developed from RGA013 were homologous to the Tomato Spotted Wilt Virus (TSWV) resistance gene. All three markers were mapped on the same linkage group AhIV. These expressed RGAs are the source for RGA-tagged marker development and identification of peanut resistance genes. | Zhanji Liu Suping Feng Manish K. Pandey Xiaoping Chen Albert K.

| 19 | An apple rootstock overexpressing a peach CBF gene alters growth and flowering in the scion but does not impact cold hardiness or dormancy显示文摘The C-repeat binding factor(CBF)transcription factor is involved in responses to low temperature and water deficit in many plant species.Overexpression of CBF genes leads to enhanced freezing tolerance and growth inhibition in many species.The overexpression of a peach CBF(PpCBF1)gene in a transgenic line of own-rooted apple(Malus×domestica)M.26 rootstock(T166)trees was previously reported to have additional effects on the onset of dormancy and time of spring budbreak.In the current study,the commercial apple cultivar‘Royal Gala’(RG)was grafted onto either non-transgenic M.26 rootstocks(RG/M.26)or transgenic M.26(T166)rootstocks(RG/T166)and field grown for 3 years.No PpCBF1 transcript was detected in the phloem or cambium of RG scions grafted on T166 rootstocks indicating that no graft transmission of transgene mRNA had occurred.In contrast to own-rooted T166 trees,no impact of PpCBF1 overexpression in T166 rootstocks was observed on the onset of dormancy,budbreak or non-acclimated leaf-cold hardiness in RG/T166 trees.Growth,however,as measured by stem caliper,current-year shoot extension and overall height,was reduced in RG/T166 trees compared with RG/M.26 trees.Although flowering was evident in both RG/T166 and RG/M.26 trees in the second season,the number of trees in flower,the number of shoots bearing flowers,and the number of flower clusters per shoot was significantly higher in RG/M.26 trees than RG/T166 trees in both the second and third year after planting.Elevated levels of RGL(DELLA)gene expression were observed in RG/T166 trees and T166 trees,which may play a role in the reduced growth observed in these tree types.A model is presented indicating how CBF overexpression in a rootstock might influence juvenility and flower abundance in a grafted scion. | Timothy S Artlip Michael E Wisniewski Rajeev Arora John L Norelli | 2016 | Horticulture Research2016,3,1: | 4 |
| 20 | Voltammetric behavior of sedative drug midazolam at glassy carbon electrode in solubilized systems显示文摘Redox behavior of midazolam was studied at a glassy carbon electrode in various buffer systems,supporting electrolytes and pH using differential pulse,square-wave and cyclic voltam-metry.Based on its reduction behavior,a direct differential pulse voltammetric method has been developed and validated for the determination of midazolam in parenteral dosage.Three well-defined peaks were observed in 0.1% SLS,Britton-Robinson (BR) buffer of pH 2.5.The effect of surfactants like sodium lauryl sulfate (SLS),cetyl trimethyl ammonium bromide (CTAB) and Tween 20 was studied.Among these surfactants SLS showed significant enhancement in reduction peak.The cathodic peak currents were directly proportional to the concentration of midazolam with correlation coefficient of 0.99. | Rajeev Jain Rajeev Kumar Yadav | 2012 | Journal of Pharmaceutical Analysis2012,2,2: | 4 |
