Anais do IV Encontro de Iniciação Científica da Unila - “UNILA 5 anos: Integração em Ciência, Tecnologia e Cultura na Tríplice Fronteira” - 05 e 06 de novembro de 2015 – Sessão Ciências Biológicas e Saúde ColetivaA satisfação com o próprio corpo tem preocupado excessivamente os jovens, especialmente as adolescentes. Além disso, a violência escolar tem despontado como um fenômeno social de grande relevância em nosso meio. O objetivo deste trabalho foi avaliar a satisfação corporal e alguns indicadores de violência escolar em crianças de uma escola pública de Foz do Iguaçu, PR. Metodologia: Foram avaliadas crianças de 7 a 9 anos de uma escola pública em Foz do Iguaçu. Resultados: Apenas 11,76% das crianças não estão completamente satisfeitas com o próprio corpo. A insatisfação segundo as partes do corpo teve a mesma frequência de 11,76% para barriga, pernas e cabelo. Assim, os alunos gostariam de mudar estas partes do corpo. Chamou a atenção que um aluno, afrodescendente, queria mudar o corpo, desejando ser branco. A frequência de alunos que já sofreram advertências na escola foi elevada (29,41%), bem como a frequência de alunos que se envolveram em brigas (29,41%). Em relação ao bullying, 29,41% já sofreram no passado e 17,65% estão passando por esta situação no presente. Apesar disso, todos os alunos consideram que as brigas na escola têm forte conotação negativa. Deve-se prestar atenção à crescente violência escolar desde a infância, sendo crucial que as escolas pensem em estratégias para enfrentar o problema.Voluntária de Iniciação Científic

Status in Diffuse Large B Cell Lymphoma not otherwise specified: A single center study from Argentina

BackgroundDiffuse large B-cell Lymphoma (DLBCL) is a heterogeneous disease. Based on Hans? algorithm, DLBCL not otherwise specified (NOS) is classified by cell-of-origin into germinal center B-cell (GCB) and non-GCB subtypes. Non-GCB ones have frequently NF-kB pathway activation and worse prognosis compared to GCB cases. MYD88 is an adaptor protein of toll-like and IL-1 receptor signalling, leading downstream NF-kB pathway activation. MYD88 L265P mutation confers the protein constitutional activation. This mutation is present in around 20% of non-GCB subtype, and rarely found in GCB subtype of DLBCL. The prognostic value of MYD88 L265P mutation in DLBCL has been matter of controversy.AimsThe aim of the study was to determine the prevalence of MYD88 L265P mutation in DLBCL NOS cases of Argentina, and compare it with previous reports in the literature.MethodsA retrospective cohort of 73 DLBCL NOS cases diagnosed in the Italian Hospital of Buenos Aires (Argentina) between 2010 and 2016 was studied. Complete clinical records, Hans? algorithm, and available material for molecular testing were inclusion criteria. Patients with prior diagnosis of low-grade lymphoma or diagnosis of immunodeficiency-associated, post-transplant, EBV+, primary mediastinal, primary testicular, primary CNS, primary effusion, leg-type or intravascular DLBCL were excluded. DNA was extracted from tissue blocks using QIAamp mini kit (Qiagen). MYD88 L265P was assessed using an in-house allele-specific probe-based Real-Time PCR assay. Positive (primary testicular DLBCL) and negative controls (tonsil) were added to each run. Every case was checked subsequently using qBiomarker MYD88 L265P Somatic Mutation Assay (Qiagen). Prevalences were expressed as percentage, confident intervals were calculated using Clopper-Pearson exact method. Kaplan Meier curves and Log-rank test were used to evaluate overall survival (OS).Results36 patients (49,31%) were female, and median age at diagnosis was 66 years (range 26-89). 33 patients (45,20%) had extranodal involvement (gastrointestinal tract: 14 cases; liver: 5 cases; bone: 4 cases; other locations: 10 cases). 44 cases (60,27%) were GCB and 29 (39,73%) were non-GCB DLBCLs. MYD88 L265P mutation was present in 2 cases (2,74% ; CI 95%: 0,33-9,55%) among all DLBCLs, including 1 GCB case (2,27% ; CI 95%: 0,06-12,02%) and 1 non-GCB case (3,45% ; CI 95%: 0,09-17.76%). There was no significant association between MYD88 L265P status, Hans´algorithm subtype, sex, age or Ki67 index and OS.ConclusionIn the analyzed population, the prevalence of GCB and non-GCB subtypes among DLBCL NOS cases was similar to international reports, although we did not find significant difference between both groups regarding OS (p=0,712). MYD88 L265P mutation was found only in 2 patients (1 GCB and 1 non-GCB), accounting for 2,74% (CI 95%: 0,33-9,55%) and 2,27% (CI 95%: 0,06-12,02%) of all DLBCL NOS and non-GCB cases, respectively. Both prevalences are significantly lower than those published in 2017 by Lee et al. in a meta-analysis, where they found that MYD88 L265P is present in 16% (CI 95%: 15-18,09%) and 20,63% (CI 95%: 18,41-23%) of patients among all DLBCLs and non-GCB subtype, respectively. However, MYD88 L265P prevalence in primary SNC, testicular and leg-type DLBCLs diagnosed in our institution are similar to the literature (data not shown).Fil: Jauk, Federico.

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

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

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

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.

Measurement of the cross-section of high transverse momentum vector bosons reconstructed as single jets and studies of jet substructure in pp collisions at √s = 7 TeV with the ATLAS detector

This paper presents a measurement of the cross-section for high transverse momentum W and Z bosons produced in pp collisions and decaying to all-hadronic final states. The data used in the analysis were recorded by the ATLAS detector at the CERN Large Hadron Collider at a centre-of-mass energy of √s = 7 TeV;{\rm Te}{\rm V}$and correspond to an integrated luminosity of$4.6\;{\rm f}{{{\rm b}}^{-1}}$. The measurement is performed by reconstructing the boosted W or Z bosons in single jets. The reconstructed jet mass is used to identify the W and Z bosons, and a jet substructure method based on energy cluster information in the jet centre-of-mass frame is used to suppress the large multi-jet background. The cross-section for events with a hadronically decaying W or Z boson, with transverse momentum${{p}_{{\rm T}}}\gt 320\;{\rm Ge}{\rm V}$and pseudorapidity$|\eta |\lt 1.9$, is measured to be${{\sigma }_{W+Z}}=8.5\pm 1.7$ pb and is compared to next-to-leading-order calculations. The selected events are further used to study jet grooming techniques
