Functional Electrical Stimulation Improves Brain Perfusion In Cranial Trauma Patients.

Demonstrate brain perfusion changes due to neuronal activation after functional electrical stimulation (FES). It was studied 14 patients with hemiplegia who were submitted to a program with FES during fourteen weeks. Brain perfusion SPECT was performed before and after FES therapy. These patients were further separated into 2 groups according to the hemiplegia cause: cranial trauma and major vascular insults. All SPECT images were analyzed using SPM. There was a significant statistical difference between the two groups related to patient's ages and extent of hypoperfusion in the SPECT. Patients with cranial trauma had a reduction in the hypoperfused area and patients with major vascular insult had an increase in the hypoperfused area after FES therapy. FES therapy can result in brain perfusion improvement in patients with brain lesions due to cranial trauma but probably not in patients with major vascular insults with large infarct area.69682-

Levantamento sorológico de anticorpos anti-Neospora caninum e anti-Toxoplasma gondii em ovinos no interior de São Paulo, SP: Serological survey of anti-Neospora caninum and anti-Toxoplasma gondii antibodies in sheep in the interior of São Paulo, SP

A ovinocultura no Brasil é uma atividade lucrativa, produzindo no ano de 2019 em torno de 19,7 milhões de cabeças. No entanto, algumas doenças podem trazer prejuízo ao produtor, como por exemplo, a neosporose e a toxoplasmose, que são responsáveis por perdas econômicas significativas especialmente devido ao abortamento. A neosporose é uma importante enfermidade causada pelo protozoário Neospora caninum. A toxoplasmose é uma zoonose de distribuição mundial, causada pelo Toxoplasma gondii, protozoário unicelular. Nesse contexto, o presente estudo teve como objetivo realizar a pesquisa de anticorpos anti-Neospora caninum e anti-Toxoplasma gondii em ovinos da região de Indaiatuba, interior do estado de São Paulo. Para tanto, foram colhidas amostras de sangue de 100 animais de diferentes idade e sexo. Para a detecção de anticorpos foram empregadas a reação de imunofluorescência indireta (RIFI). Para a detecção de IgG anti-Neospora caninum foi utilizado como antígeno taquizoítos da cepa NC-1. Como anticorpo secundário foi utilizado o conjugado comercial anti-ovino IgG (Sigma, USA, F7887) marcado com isotiocianato de fluoresceína. Para a detecção de anticorpos IgG anti-Toxoplasma gondii foi adotado o protocolo preconizado por Camargo (1964), utilizando-se anticorpos anti-IgG-ovino (Sigma®) conjugado ao isotiocianato de fluoresceína, com ponto de corte 64, utilizando-se como antígeno, taquizoítos da cepa RH. Em todas as reações foram incluídos controle positivo e negativo, previamente conhecidos. A RIFI foi realizada no Departamento de Medicina Veterinária (DMV), da Universidade Federal Rural de Pernambuco (UFRPE). Dos 100 animais testados para Neospora caninum, os resultados do teste de sorodiagnóstico indicaram 12% (12/100) de animais positivos, sendo 25% (3/12) filhotes, 25% (3/12) jovens e 50% (6/12) adultos. Em relação ao sexo, 16,70% (2/12) eram machos e 83,30% (10/12) fêmeas. Os resultados para Toxoplasma gondii indicaram 37% (37/100) de animais soropositivos. Em relação a idade, observou-se 16,22% (6/37) filhotes, 2,70% (1/37) jovens e 81,08% (30/37) adultos. Em relação ao sexo verificou-se que dos animais positivos, 27,02% (10/37) eram machos e 72,97% (27/37) fêmeas. Com base nos resultados do presente estudo concluiu-se que a ocorrência de animais com neoporose e toxoplasmose é expressiva na propriedade pesquisada. Novos estudos devem ser conduzidos para verificação dos fatores de riscos a fim de adotarem medidas de prevenção e controle

<i>Gaia</i> Data Release 1. Summary of the astrometric, photometric, and survey properties

Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illustrations of the scientific quality of the data, followed by a discussion of the limitations due to the preliminary nature of this release. Methods. The raw data collected by Gaia during the first 14 months of the mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC) and turned into an astrometric and photometric catalogue. Results. Gaia DR1 consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the HIPPARCOS and Tycho-2 catalogues – a realisation of the Tycho-Gaia Astrometric Solution (TGAS) – and a secondary astrometric data set containing the positions for an additional 1.1 billion sources. The second component is the photometric data set, consisting of mean G-band magnitudes for all sources. The G-band light curves and the characteristics of ∼3000 Cepheid and RR-Lyrae stars, observed at high cadence around the south ecliptic pole, form the third component. For the primary astrometric data set the typical uncertainty is about 0.3 mas for the positions and parallaxes, and about 1 mas yr−1 for the proper motions. A systematic component of ∼0.3 mas should be added to the parallax uncertainties. For the subset of ∼94 000 HIPPARCOS stars in the primary data set, the proper motions are much more precise at about 0.06 mas yr−1. For the secondary astrometric data set, the typical uncertainty of the positions is ∼10 mas. The median uncertainties on the mean G-band magnitudes range from the mmag level to ∼0.03 mag over the magnitude range 5 to 20.7. Conclusions. Gaia DR1 is an important milestone ahead of the next Gaia data release, which will feature five-parameter astrometry for all sources. Extensive validation shows that Gaia DR1 represents a major advance in the mapping of the heavens and the availability of basic stellar data that underpin observational astrophysics. Nevertheless, the very preliminary nature of this first Gaia data release does lead to a number of important limitations to the data quality which should be carefully considered before drawing conclusions from the data

Measurement of χ c1 and χ c2 production with s√ = 7 TeV pp collisions at ATLAS

The prompt and non-prompt production cross-sections for the χ c1 and χ c2 charmonium states are measured in pp collisions at s√ = 7 TeV with the ATLAS detector at the LHC using 4.5 fb−1 of integrated luminosity. The χ c states are reconstructed through the radiative decay χ c → J/ψγ (with J/ψ → μ + μ −) where photons are reconstructed from γ → e + e − conversions. The production rate of the χ c2 state relative to the χ c1 state is measured for prompt and non-prompt χ c as a function of J/ψ transverse momentum. The prompt χ c cross-sections are combined with existing measurements of prompt J/ψ production to derive the fraction of prompt J/ψ produced in feed-down from χ c decays. The fractions of χ c1 and χ c2 produced in b-hadron decays are also measured

Search for squarks and gluinos in events with isolated leptons, jets and missing transverse momentum at s√=8 TeV with the ATLAS detector

The results of a search for supersymmetry in final states containing at least one isolated lepton (electron or muon), jets and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. The search is based on proton-proton collision data at a centre-of-mass energy s√=8 TeV collected in 2012, corresponding to an integrated luminosity of 20 fb−1. No significant excess above the Standard Model expectation is observed. Limits are set on supersymmetric particle masses for various supersymmetric models. Depending on the model, the search excludes gluino masses up to 1.32 TeV and squark masses up to 840 GeV. Limits are also set on the parameters of a minimal universal extra dimension model, excluding a compactification radius of 1/R c = 950 GeV for a cut-off scale times radius (ΛR c) of approximately 30

Measurements of fiducial and differential cross sections for Higgs boson production in the diphoton decay channel at s√=8 TeV with ATLAS

Measurements of fiducial and differential cross sections are presented for Higgs boson production in proton-proton collisions at a centre-of-mass energy of s√=8 TeV. The analysis is performed in the H → γγ decay channel using 20.3 fb−1 of data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The signal is extracted using a fit to the diphoton invariant mass spectrum assuming that the width of the resonance is much smaller than the experimental resolution. The signal yields are corrected for the effects of detector inefficiency and resolution. The pp → H → γγ fiducial cross section is measured to be 43.2 ±9.4(stat.) − 2.9 + 3.2 (syst.) ±1.2(lumi)fb for a Higgs boson of mass 125.4GeV decaying to two isolated photons that have transverse momentum greater than 35% and 25% of the diphoton invariant mass and each with absolute pseudorapidity less than 2.37. Four additional fiducial cross sections and two cross-section limits are presented in phase space regions that test the theoretical modelling of different Higgs boson production mechanisms, or are sensitive to physics beyond the Standard Model. Differential cross sections are also presented, as a function of variables related to the diphoton kinematics and the jet activity produced in the Higgs boson events. The observed spectra are statistically limited but broadly in line with the theoretical expectations
