Comparative Study of the Standard Fluorescent Antibody to Membrane Antigen (FAMA) Assay and a Flow Cytometry-Adapted FAMA Assay To Assess Immunity to Varicella-Zoster Virus

A flow cytometry-adapted fluorescent antibody to membrane antigen (FAMA) assay to detect IgG antibodies against varicella-zoster virus (VZV) was developed and tested in 62 serum samples, showing 90.32% accuracy obtained from a receiver operating characteristic (ROC) curve with a 0.9125 (95% confidence interval [CI], 0.829 to 1.00) area below the curve compared to the result with standard FAMA.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fed Univ São Paulo UNIFESP EPM, Div Pediat Infect Dis, BR-04040000 São Paulo, BrazilColumbia Univ, Dept Pediat, Coll Phys & Surg, New York, NY 10027 USAFed Univ São Paulo UNIFESP EPM, Div Pediat Infect Dis, BR-04040000 São Paulo, BrazilCAPES: 0108-08-1Web of Scienc

Isolado proteico obtido de subproduto do processamento da castanha de caju.

A amêndoa da castanha de caju é o produto com maior valor econômico do cajueiro, rica em proteínas e ácidos graxos poli-insaturados. Entre os subprodutos do beneficiamento da castanha estão as amêndoas quebradas, de onde se extrai o óleo comestível, resultando em uma farinha desengordurada. Neste trabalho descrevem-se as características do isolado proteico da amêndoa da castanha de caju, obtido a partir da farinha desengordurada, por solubilização das proteínas em condições alcalinas e posterior precipitação ácida. O isolado obtido apresentou 86,2% de proteínas e rendimento em massa de 19,0%, tendo carboidratos, lipídeos e cinzas como componentes minoritários. Quanto às características tecnológicas, o isolado apresentou capacidade de absorção de água de 1,74 mL/g, capacidade de absorção de óleo de 0,90 mL/g, capacidade de formação de espuma de 10%e baixa solubilidade em meio aquoso. Proteínas com esse perfil são indicadas para uso em alimentos semissólidos como iogurtes, sólidos como embutidos cárneos ou mesmo alimentos nos quais se exige aeração, como mousses. The cashew nut kernel is the product with the highest economic value of the cashew tree, rich in proteins and polyunsaturated fatty acids.Among the by-products of nut processing are broken kernels, from whichedible oil is extracted, resulting in a defatted flour. This work describes the characteristics of a protein isolate from cashew nut kernel, obtained from defatted flour, by solubilization of proteins in alkaline conditions and subsequentacid precipitation. The isolate obtained showed 86.2% protein and mass yield of 19.0%, with carbohydrates, lipids and ashes as minor components. As forthe technological characteristics, the isolate had water absorption capacity of 1.74 mL/g, oil absorption capacity of 0.90 mL/g, foaming capacity of 10% and low solubility in aqueous medium. Proteins with this profile are suitable for use in semi-solid foods such as yogurts, solids such as meat sausages or even those foods requiring aeration, such as mousses

Single hadron response measurement and calorimeter jet energy scale uncertainty with the ATLAS detector at the LHC

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of sqrt(s) = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of K_s and Lambda particles, the calorimeter response to specific types of particles (positively and negatively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral particles to jets. The response uncertainty is 2-5% for central isolated hadrons and 1-3% for the final calorimeter jet energy scale.Comment: 24 pages plus author list (36 pages total), 23 figures, 1 table, submitted to European Physical Journal

Standalone vertex finding in the ATLAS muon spectrometer

A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to bbar b final states, and pp collision data at √s = 7 TeV collected with the ATLAS detector at the LHC during 2011

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson

Measurement of the flavour composition of dijet events in pp collisions at root s=7 TeV with the ATLAS detector

This paper describes a measurement of the flavour composition of dijet events produced in pp collisions at √s=7 TeV using the ATLAS detector. The measurement uses the full 2010 data sample, corresponding to an integrated luminosity of 39 pb−1. Six possible combinations of light, charm and bottom jets are identified in the dijet events, where the jet flavour is defined by the presence of bottom, charm or solely light flavour hadrons in the jet. Kinematic variables, based on the properties of displaced decay vertices and optimised for jet flavour identification, are used in a multidimensional template fit to measure the fractions of these dijet flavour states as functions of the leading jet transverse momentum in the range 40 GeV to 500 GeV and jet rapidity |y|<2.1. The fit results agree with the predictions of leading- and next-to-leading-order calculations, with the exception of the dijet fraction composed of bottom and light flavour jets, which is underestimated by all models at large transverse jet momenta. The ability to identify jets containing two b-hadrons, originating from e.g. gluon splitting, is demonstrated. The difference between bottom jet production rates in leading and subleading jets is consistent with the next-to-leading-order predictions

Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance of b-tagging and the trigger. The physics potential for a variety of interesting physics processes, within the Standard Model and beyond, is examined. The study comprises a series of notes based on simulations of the detector and physics processes, with particular emphasis given to the data expected from the first years of operation of the LHC at CERN
