The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,plays an important role in v.r.ous analyses performed at the Large Hadron Collider,as Standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced background.This paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collaboration,using √s=13 Tev proton–proton collision data with an integrated luminosity of 140 fb^(-1) collected by the ATLAS experiment.Two taggers with high performances in rejecting jets from gluon ov.r.jets from quarks are studied:one tagger is based on requirements on the number of inner-detector tracks associated with the jet,and the other combines sev.r.l jet substructure observables using a boosted decision tree.A method is established to determine the quark/gluon fraction in data,by using quark/gluon-enriched subsamples defined by the jet pseudorapidity.Differences in tagging efficiency between data and simulation are provided for jets with transv.r.e momentum between 500 Gev and 2 Tev and for multiple tagger working points.

Next Generation Transcriptome Sequencing and Quantitative real-Time PCr Technologies for Characterisation of the Bemisia tabaci Asia 1 mtCOI Phylogenetic Clade

引用

Journal of Integrative Agriculture 2012年第2期11卷 281-292页

作者： Susan Seal Mitulkumar v Patel Carl Collins John Colvin David bailey Natural resources Institute University of GreenwichChatham Maritime Kent ME4 4TBUnited Kingdom

A programme of functional genomics research is underway at the Univ.r.ity of Greenwich,UK,to develop and apply genomics technologies to characterise an economically-important but under-researched Bemisia tabaci（Hemiptera：Aleyrodidae）,the Asia 1 mtCOI phylogenetic group.A comparison of this putative species from India with other important B.tabaci populations and insect species may provide targets for the development of more effective whitefly control strategies.As a first step,next-generation sequencing（NGS）has been used to survey the transcriptome of adult female whitefly,with high quality rNA preparations being used to generate cDNA libraries for NGS using the roche 454 Titanium DNA sequencing platform.Contig assemblies constructed from the resultant sequences（301 094 reads）using the software program CLC Genomics Workbench generated 3 821 core contigs.Comparison of a selection of these contigs with related sequences from other B.tabaci genetic groups has revealed good alignment for some genes（e.g.,HSP90）but misassemblies in other datasets（e.g.,the vitellogenin gene family）,highlighting the need for manual curation as well as collaborative international efforts to obtain accurate assemblies from the existing next generation sequence datasets.Nev.r.heless,data emerging from the NGS has facilitated the development of accurate and reliable methods for analysing gene expression based on quantitative real-time rT-PCr,illustrating the power of this approach to enable rapid expression analyses in an organism for which a complete genome sequence is currently lacking.

Activation of Astrocytes in vitro by Macrophages Polarized with Keratin Biomaterial Treatment

引用

Open Journal of regenerative Medicine 2016年第1期5卷 1-13页

作者： bailey v. Fearing Mark E. van Dyke Department of Orthopaedic Surgery Wake Forest University School of Medicine Winston Salem NC USA Department of Biomedical Engineering and Mechanics Virginia Polytechnic Institute and State University Blacksburg VA USA

reactive astrocytes contribute to glial scarring by rapid proliferation and up-regulation of glial fibrillary acidic protein (GFAP) expression and production of chondroitin sulfate proteoglycans (CSPGs). CSPGs play a crucial role in formation of the glial scar, which takes ov.r.the lesion site following spinal cord injury (SCI). This process corresponds to the inflammatory response of macrophages, which polarize toward a dominant pro-inflammatory M1 phenotype following SCI. The M1 phenotype is known to release v.r.ous cytotoxic compounds that exacerbate the glial scar, which in turn impedes tissue regeneration. recent studies have shown that anti-inflammatory M2 macrophages play a role in allowing neurite extensions to occur, even across inhibitory substrates, and can lessen the degree of secondary damage. Based on earlier results demonstrating that keratin biomaterials may polarize macrophages toward an anti-inflammatory M2 phenotype, we test the hypothesis that these polarized macrophages will have the potential to indirectly effect astrogliosis. Using an in vitro model of reactive astrogliosis, macrophage-conditioned media from cells that have been cultured with soluble keratin for 24 hours or 7 days appears to decrease reactivity and associates CSPG production. These results are statistically similar to the control M2 macrophage conditioned media. A comparable collagen-conditioned macrophage media does not resolve astrocyte reactivity, while control M1 macrophage conditioned media results in an increase in GFAP expression. These data suggest keratin-derived macrophages are more functionally similar to M2 macrophages and that keratin treatment may aid in limiting secondary inflammatory-mediated damage.

Trace elements migrating from tailings to rock v.r.ish laminated sediments in an old mining region from Nelson,Nevada,USA

International Journal of Sediment research 2022年第2期37卷 202-213页

作者： Douglas B.Sims Amanda C.Hudson John E.Keller Michael Strange Andressa Cristhy Buch David Ferrari Giavanna M.Fernandez Juan Garcia-Hernandez bailey D.Kesl Sean Torres Department of Physical Sciences College of Southern Nevada Univ.r.ity of Nevada Fluminense Federal Univ.r.ity

The dispersion and influence of soluble and particulate trace elements(TEs) present in the materials from abandoned mines is an imminent problem on terrestrial and aquatic env.r.nments.The goal of this research is to provide a broader view of such transport,assessing particle size distribution and TE interactions(e.g.,scavenging) with mine tailings and locally derived sediments transported by water in arid region.Sand grains from wash sediment were collected from a dry ephemeral wash in Nelson,Nevada where the Techatticup Mine and Mill worked between 1850 and 1960.Samples were evaluated to determine the association and behavior of certain metals and metalloids including aluminum,arsenic,barium,cadmium,copper,chromium,iron,manganese,lead,selenium,vanadium,and zinc to rock v.r.ish laminated sediments.results show that some metals and metalloids were more concentrated on larger particles whereas others indicated the opposite tendency.For example,As was greatest on silt fractions and least on coarse fractions,while Se was detected only on silts.Cr,Cu,Fe,Mn,Pb,and Zn concentrations all increased with decreasing particle size(silt> sand> coarse),whereas Al,Ba,and v showed the opposite trend(silt rse).The enrichment factor(EF) of Cu,Zn,Pb,As,and Se were lower in mine tailing sediment treated with wash than those obtained for source material.Howev.r.in treated wash sediment samples,the high EFs of Ba,Cr,v,and Mn suggested a possible greater affinity of these metals to the Al,Fe,and Mn oxides from the rv sediment.The data found in this study show that transport of contaminated sediments in arid regions could lead to the enrichment of some TEs in downgradient areas from source materials.

AIM:To investigate genetic differences between Crohn's disease(CD) patients with a sustained remission vs relapsers after discontinuing infliximab while in corticosteroid-free remission.METHODS:Forty-eight CD patients received infliximab and were in full corticosteroid-free clinical remission but then discontinued infliximab for reasons other than a loss of response,were identified by review of an electronic database and charts.Infliximab-associated remission was defined as corticosteroid-free plus normalization of clinical disease activity [CD activity index(CDAI) ring follow-up visits based on physician global assessments.A CD relapse(loss of infliximab-induced remission) was clinically defined as a physician visit for symptoms of disease activity(CDAI > 220) and a therapeutic intervention with CD medication(s),or a hospitalization with complications related to active CD.Genetic analyses were performed on samples from 14 patients(n = 6 who had a sustained long term remission after stopping infliximab,n = 8 who rapidly relapsed after stopping infliximab).Nucleotide-binding oligomerization domain 2(NOD2)/caspase activation recruitment domain 15(CArD15) polymorphisms(r702W,G908r and L1007fs) and the inflammatory bowel disease 5(IBD5) polymorphisms(IGr2060a1 and IGr3081a1) were analyzed in each group.rESULTS:Five single nucleotide polymorphisms of IBD5 and NOD2/CArD15 genes were successfully analyzed for all 14 subjects.There was no significant increase in frequency of the NOD2/CArD15 polymorphisms(r702W,G908r and L1007fs) and the IBD5 polymorphisms(IGr2060a1 and IGr3081a1) in either group of patients;those whose disease relapsed rapidly or those who remained in sustained long term remission following the discontinuation of infliximab.Nearly a third of patients in full clinical remission who stopped infliximab for reasons other than loss of response remained in sustained clinical remission,while two-thirds relapsed rapidly.There was a marked difference in the duration of clinical remission following discon
