Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

Jet size dependence of single jet suppression in lead-lead collisions at sqrt(s(NN)) = 2.76 TeV with the ATLAS detector at the LHC

Measurements of inclusive jet suppression in heavy ion collisions at the LHC provide direct sensitivity to the physics of jet quenching. In a sample of lead-lead collisions at sqrt(s) = 2.76 TeV corresponding to an integrated luminosity of approximately 7 inverse microbarns, ATLAS has measured jets with a calorimeter over the pseudorapidity interval |eta| < 2.1 and over the transverse momentum range 38 < pT < 210 GeV. Jets were reconstructed using the anti-kt algorithm with values for the distance parameter that determines the nominal jet radius of R = 0.2, 0.3, 0.4 and 0.5. The centrality dependence of the jet yield is characterized by the jet "central-to-peripheral ratio," Rcp. Jet production is found to be suppressed by approximately a factor of two in the 10% most central collisions relative to peripheral collisions. Rcp varies smoothly with centrality as characterized by the number of participating nucleons. The observed suppression is only weakly dependent on jet radius and transverse momentum. These results provide the first direct measurement of inclusive jet suppression in heavy ion collisions and complement previous measurements of dijet transverse energy imbalance at the LHC.Comment: 15 pages plus author list (30 pages total), 8 figures, 2 tables, submitted to Physics Letters B.

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Evaluation Of Users Of Basic Attention Healthcare About The Implantation Of An Integral Dental Assistance Protocol [avaliação De Usuários Da Atenção Básica Sobre A Implantação De Protocolo De Assistência Integral Odontológica]

Objective: To evaluate the perception of basic attention healthcare users as to the implantation of the Integral Dental Assistance Protocol (PAIO, in Portuguese) and the effect of this program on the oral health condition, oral hygiene, access to and resolubility of the service, in a public basic health unit of João Pessoa-PB. Method: The sample was composed of 32 volunteers, for whom a sixphase intervention was programed: diagnosis of dental needs; resolution of urgencies; restorative interventions; application of promotional measures; evaluation of the health level obtained; and periodic follow-up visits. Data were collected by means of a semistructured interview and a questionnaire, applied before and after PAIO implantation. The interviews were transcribed and analyzed according to the content analysis technique. The effect of PAIO implantation was evaluated by using an increasing scoring system ranging from 1 to 10. The Wilcoxon test was applied with a confidence level of 95%. Results: For the participants that attended the PAIO (n=20), the program contributed to improve oral health condition (100%) and knowledge (100%). The users reported satisfaction (n=12) and had a positive evaluation (n=12), achieved by means of the improvement of oral health condition (n=8), faster and easier access to treatment (n=7), scheduling of dental appoints and warrant of being treated (n=6), welcoming (n=5), motivation for oral care (n=5), and perspective of continuity of PAIO (n=6). The initial evaluation of the users received scores between 5.7 and 7.6. After PAIO implantation, the users' perception was improved (p<0.01), with scores between 9.6 and 9.9. Conclusion: According to the users, the implantation of PAIO contributed to the qualification of health service and oral health care, being a favorable aspect to increase the access to and resolubility of the service.123405412(2004) Coordenação Nacional de Saúde Bucal, , Brasil, Ministério da Saúde, Política Nacional de Saúde Bucal.

Podem as bactérias ácido lácticas probióticas apresentarem efeito antitumoral em modelo animal de câncer de cólon? Uma revisão da literatura

RESUMO: O Câncer de cólon é um dos tipos mais comuns de câncer no mundo e a segunda principal causa de morte relacionada a esta doença em países desenvolvidos. Até 75% dos casos estão associados com a alimentação, indicando que uma pessoa pode reduzir o seu risco simplesmente através de modificação na dieta. Estudos em animais demonstram que várias cepas de bactérias ácido lácticas protegem contra o câncer de cólon em roedores, embora os dados em humanos sejam limitados e conflitantes. O objetivo deste estudo foi investigar a eficácia das bactérias ácido lácticas no tratamento e redução do câncer de cólon em modelo animal. Foram realizadas buscas sistemáticas em bases de dados eletrônicas alcançando 1079 artigos relacionados, entretanto apenas 6 artigos foram eleitos de acordo com os critérios de elegibilidade para análise. Todos os artigos avaliados apresentaram resultados satisfatórios quanto à inibição do câncer de cólon em ratos e camundongos ao utilizarem cepas predominantemente do gênero Lactobacillus. Este estudo pode responder a hipótese de que as bactérias ácido lácticas apresentam efeito preventivo e antitumoral contra o câncer de cólon
