IMPROVEMENTS IN LOWER-LIMB STRENGTH ARE ASSOCIATED WITH HIP CONTROL DURING LOAD CARRIAGE IN FEMALES

The purpose of this study was to investigate the effect of lower-limb strength on lower-limb biomechanical responses over the duration of a load carriage march. Female civilians (n=12) completed a 5 km march at 5.5 km·h-1 wearing a 23 kg external load before and after 10 weeks of hip-focussed training. Lower-limb 3D kinematics were acquired during the march, with lower-limb strength measures assessed prior to pre- and post-training marching tasks. Significant increases in lower-limb strength were elicited after training, alongside moderate to strong negative correlations between strength and hip adduction (

Suspensão da descrença : uma intervenção de literatura no campo da saúde

O atual modelo assistencial à saúde da população brasileira caracteriza-se por grande desenvolvimento científico e tecnológico, destacando a criação de procedimentos terapêuticos com grande efetividade, bem como a hegemonia de modelo de atenção à saúde, podendo influenciar em uma organização dos serviços centrada nos hospitais e na valorização de especialistas que operam essa complexidade tecnológica. Considerando que o processo de produção do cuidado em saúde envolve ações para além de rotinas, protocolos e procedimentos, torna-se necessário um movimento paralelo de investir em tecnologias que ampliem as capacidades relacionais entre os atores envolvidos, principalmente no que tange à competência de dialogar com o outro. Considerando que a literatura, em suas diversas estruturas narrativas e poéticas, provoca sempre uma relação dialética entre aquele que enuncia e o receptor, este trabalho trata de apresentar uma intervenção de aplicação da literatura com trabalhadores de equipes multiprofissionais de unidades hospitalares de um grupo hospitalar do sistema único de saúde. Tomando como referencial teórico as teses de Walter Benjamin, Mikhail Bakhtin e Paul Ricoeur, a investigação envolveu a elaboração, aplicação, validação e interpretação de uma metodologia a partir do compartilhamento de leitura literária e escrita criativa. Uma aposta de que o encontro dialógico, pela narrativa, potencializa a curiosidade e interesse pelo outro, a coragem ética para a tomada de decisão e o desejo de compreender e ser compreendido, compartilhando um sistema de valores coletivos que se materialize em ações de cuidado em saúde. Por sua capacidade de comunicar um acontecimento sem necessariamente produzir um relato informativo, cronológico, a narrativa também foi utilizada como estratégia metodológica de pesquisa. Como material de interpretação utilizou-se as notas de caderno de campo da pesquisadora e os textos produzidos pelos participantes da pesquisa que, inseridos no conceito das técnicas de pesquisa qualitativa, compõem o movimento circular de interpretação. Além da estrutura narrativa, verificou-se que os textos produzidos enunciam uma variedade de semânticas, verdades, discursos, línguas e vozes sociais que contribuem para a produção de sentido sobre o cotidiano do trabalho em saúde. Ao final, o trabalho apresenta o resultado de um processo que, apoiado e acompanhado pela literatura, possibilita novas formas de notar, narrar e compreender melhor a vida no o cotidiano do trabalho de produção do cuidado.The current health care model in Brazil is characterized by great scientific and technological development, highlighting the creation of therapeutic procedures with great effectiveness, as well as the hegemony of a health care model, which may influence a hospital-centered organization of services and the valorization of specialists who operate this technological complexity. Considering that the process of production of health care involves actions that go beyond routines, protocols and procedures, a parallel movement of investing in technologies that enhance relational capacities among the actors involved is necessary, mainly with regard to the competence to dialogue with the other. Considering that literature, in its various narrative and poetic structures, always provokes a dialectic relationship between the one that enunciates and the receiver, this paper aims at presenting an intervention of literature application with workers of multiprofessional teams in hospital units of a Public Health System hospital group. Taking as theoretical reference the theses of Walter Benjamin, Mikhail Bakhtin and Paul Ricoeur, the research involved the elaboration, application, validation and interpretation of a methodology through the sharing of literary reading and creative writing. A bet that the dialogical encounter, through narrative, enhances curiosity and interest towards the other, the ethical courage to make a decision and the desire to understand and be understood, sharing a system of collective values that materialize in health care actions. For its potential to communicate an event without necessarily producing an informative, chronological narrative, the narrative was also used as a methodological research strategy. As interpretive material, the researcher's field notes and the texts produced by the participants were used which, inserted in the concept of qualitative research techniques, make up the circular interpretation movement. In addition to the narrative structure, it was verified that the texts produced enunciate a variety of semantics, truths, discourses, languages and social voices that contribute to the production of meaning on the daily work in health care. At the end, the work presents the result of a process that, supported and accompanied by literature, enables new ways of noting, narrating and understanding life better in the daily work of care production

An Integrated TCGA Pan-Cancer Clinical Data Resource to Drive High-Quality Survival Outcome Analytics

For a decade, The Cancer Genome Atlas (TCGA) program collected clinicopathologic annotation data along with multi-platform molecular profiles of more than 11,000 human tumors across 33 different cancer types. TCGA clinical data contain key features representing the democratized nature of the data collection process. To ensure proper use of this large clinical dataset associated with genomic features, we developed a standardized dataset named the TCGA Pan-Cancer Clinical Data Resource (TCGA-CDR), which includes four major clinical outcome endpoints. In addition to detailing major challenges and statistical limitations encountered during the effort of integrating the acquired clinical data, we present a summary that includes endpoint usage recommendations for each cancer type. These TCGA-CDR findings appear to be consistent with cancer genomics studies independent of the TCGA effort and provide opportunities for investigating cancer biology using clinical correlates at an unprecedented scale. Analysis of clinicopathologic annotations for over 11,000 cancer patients in the TCGA program leads to the generation of TCGA Clinical Data Resource, which provides recommendations of clinical outcome endpoint usage for 33 cancer types

Flavor Production in Pb(160AGeV) on Pb Collisions: Effect of Color Ropes and Hadronic Rescattering

Collective interactions in the preequilibrium quark matter and hadronic resonance gas stage of ultrarelativistic nucleus-nucleus collisions are studied in the framework of the the transport theoretical approach RQMD. The paper reviews string fusion into color ropes and hadronic rescattering which serve as models for these interactions. Hadron production in central Pb(160AGeV) on Pb collisions has been calculated. The changes of the final flavor composition are more pronounced than in previous RQMD studies of light ion induced reactions at 200AGeV. The ratio of created quark pairs $s\bar{s}$/($u\bar{u}$+$d\bar{d}$) is enhanced by a factor of 2.4 in comparison to $pp$ results. Color rope formation increases the initially produced antibaryons to 3 times the value in the `NN mode', but only one quarter of the produced antibaryons survives because of subsequent strong absorption. The differences in the final particle composition for Pb on Pb collisions compared to S induced reactions are attributed to the hadronic resonance gas stage which is baryon-richer and lasts longer.Comment: 60 pages + 11 postscript figures (uuencoded and included

Driver Fusions and Their Implications in the Development and Treatment of Human Cancers.

Gene fusions represent an important class of somatic alterations in cancer. We systematically investigated fusions in 9,624 tumors across 33 cancer types using multiple fusion calling tools. We identified a total of 25,664 fusions, with a 63% validation rate. Integration of gene expression, copy number, and fusion annotation data revealed that fusions involving oncogenes tend to exhibit increased expression, whereas fusions involving tumor suppressors have the opposite effect. For fusions involving kinases, we found 1,275 with an intact kinase domain, the proportion of which varied significantly across cancer types. Our study suggests that fusions drive the development of 16.5% of cancer cases and function as the sole driver in more than 1% of them. Finally, we identified druggable fusions involving genes such as TMPRSS2, RET, FGFR3, ALK, and ESR1 in 6.0% of cases, and we predicted immunogenic peptides, suggesting that fusions may provide leads for targeted drug and immune therapy

Measurement of W± and Z-boson production cross sections in pp collisions at √s=13 TeV with the ATLAS detector

See paper for full list of authors - 17 pages plus author list + cover pages (34 pages total), 5 figures, 3 tables, submitted to Phys. Lett. B, All figures including auxiliary figures are available at https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/STDM-2015-03/International audienceMeasurements of the $W^{\pm} \rightarrow \ell^{\pm} \nu$ and $Z \rightarrow \ell^+ \ell^-$ production cross sections (where $\ell^{\pm}=e^{\pm},\mu^{\pm}$) in proton-proton collisions at $\sqrt{s}=13$ TeV are presented using data recorded by the ATLAS experiment at the Large Hadron Collider, corresponding to a total integrated luminosity of 81 pb$^{-1}$. The total inclusive $W^{\pm}$-boson production cross sections times the single-lepton-flavour branching ratios are $\sigma_{W^+}^{tot}= 11.78 \pm 0.02 (stat) \pm 0.32 (sys) \pm 0.59 (lumi)$ nb and $\sigma_{W^-}^{tot} = 8.75 \pm 0.02 (stat) \pm 0.24 (sys) \pm 0.44 (lumi)$ nb for $W^+$ and $W^-$, respectively. The total inclusive $Z$-boson production cross section times leptonic branching ratio, within the invariant mass window $66 < m_{\ell\ell} < 116$ GeV, is $\sigma_{Z}^{tot} = 1.97 \pm 0.01 (stat) \pm 0.04 (sys) \pm 0.10 (lumi)$ nb. The $W^+$, $W^-$, and $Z$-boson production cross sections and cross-section ratios within a fiducial region defined by the detector acceptance are also measured. The cross-section ratios benefit from significant cancellation of experimental uncertainties, resulting in $\sigma_{W^+}^{fid}/\sigma_{W^-}^{fid} = 1.295 \pm 0.003 (stat) \pm 0.010 (sys)$ and $\sigma_{W^{\pm}}^{fid}/\sigma_{Z}^{fid} = 10.31 \pm 0.04 (stat) \pm 0.20 (sys)$. Theoretical predictions, based on calculations accurate to next-to-next-to-leading order for quantum chromodynamics and next-to-leading order for electroweak processes and which employ different parton distribution function sets, are compared to these measurements

Measurement of the charge asymmetry in highly boosted top-quark pair production in √s=8 TeV pp collision data collected by the ATLAS experiment

In the pp→tt process the angular distributions of top and anti-top quarks are expected to present a subtle difference, which could be enhanced by processes not included in the Standard Model. This Letter presents a measurement of the charge asymmetry in events where the top-quark pair is produced with a large invariant mass. The analysis is performed on 20.3 fb-1 of pp collision data at √s=8TeV collected by the ATLAS experiment at the LHC, using reconstruction techniques specifically designed for the decay topology of highly boosted top quarks. The charge asymmetry in a fiducial region with large invariant mass of the top-quark pair (mtt>0.75 TeV) and an absolute rapidity difference of the top and anti-top quark candidates within -2<|yt|-|yt|<2 is measured to be 4.2±3.2%, in agreement with the Standard Model prediction at next-to-leading order. A differential measurement in three tt- mass bins is also presented

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum with ATLAS using root s=13 TeV proton-proton collisions

Results are reported of a search for new phenomena, such as supersymmetric particle production, that could be observed in high-energy proton-proton collisions. Events with large numbers of jets, together with missing transverse momentum from unobserved particles, are selected. The data analysed were recorded by the ATLAS experiment during 2015 using the 13 TeV centre-of-mass proton-proton collisions at the Large Hadron Collider, and correspond to an integrated luminosity of 3.2 fb(-1). The search selected events with various jet multiplicities from >= 7 to >= 10 jets, and with various b-jet multiplicity requirements to enhance sensitivity. No excess above Standard Model expectations is observed. The results are interpreted within two supersymmetry models, where gluino masses up to 1400 GeV are excluded at 95% confidence level, significantly extending previous limits.

Genomic and Functional Approaches to Understanding Cancer Aneuploidy

Aneuploidy, whole chromosome or chromosome arm imbalance, is a near-universal characteristic of human cancers. In 10,522 cancer genomes from The Cancer Genome Atlas, aneuploidy was correlated with TP53 mutation, somatic mutation rate, and expression of proliferation genes. Aneuploidy was anti-correlated with expression of immune signaling genes, due to decreased leukocyte infiltrates in high-aneuploidy samples. Chromosome arm-level alterations show cancer-specific patterns, including loss of chromosome arm 3p in squamous cancers. We applied genome engineering to delete 3p in lung cells, causing decreased proliferation rescued in part by chromosome 3 duplication. This study defines genomic and phenotypic correlates of cancer aneuploidy and provides an experimental approach to study chromosome arm aneuploidy. Analyzing >10,000 human cancers, Taylor et al. show that aneuploidy is correlated with somatic mutation rate, expression of proliferation genes, and decreased leukocyte infiltration. Loss of chromosome arm 3p is common in squamous cancers, but deletion of chromosome 3p reduces cell proliferation in vitro

Genomic and Molecular Landscape of DNA Damage Repair Deficiency across The Cancer Genome Atlas

DNA damage repair (DDR) pathways modulate cancer risk, progression, and therapeutic response. We systematically analyzed somatic alterations to provide a comprehensive view of DDR deficiency across 33 cancer types. Mutations with accompanying loss of heterozygosity were observed in over 1/3 of DDR genes, including TP53 and BRCA1/2. Other prevalent alterations included epigenetic silencing of the direct repair genes EXO5, MGMT, and ALKBH3 in 3c20% of samples. Homologous recombination deficiency (HRD) was present at varying frequency in many cancer types, most notably ovarian cancer. However, in contrast to ovarian cancer, HRD was associated with worse outcomes in several other cancers. Protein structure-based analyses allowed us to predict functional consequences of rare, recurrent DDR mutations. A new machine-learning-based classifier developed from gene expression data allowed us to identify alterations that phenocopy deleterious TP53 mutations. These frequent DDR gene alterations in many human cancers have functional consequences that may determine cancer progression and guide therapy. Knijnenburg et al. present The Cancer Genome Atlas (TCGA) Pan-Cancer analysis of DNA damage repair (DDR) deficiency in cancer. They use integrative genomic and molecular analyses to identify frequent DDR alterations across 33 cancer types, correlate gene- and pathway-level alterations with genome-wide measures of genome instability and impaired function, and demonstrate the prognostic utility of DDR deficiency scores
