Measurements of Higgs boson properties in the diphoton decay channel in proton-proton collisions at √s=13 TeV

Abstract: Measurements of Higgs boson properties in the H → γγ decay channel are reported. The analysis is based on data collected by the CMS experiment in proton-proton collisions at $ \sqrt{s}=13 $ TeV during the 2016 LHC running period, corresponding to an integrated luminosity of 35.9 fb$^{−1}$. Allowing the Higgs mass to float, the measurement yields a signal strength relative to the standard model prediction of 1.18$_{− 0.14}^{+ 0.17}$ = 1.18$_{− 0.11}^{+ 0.12}$ (stat)$_{− 0.07}^{+ 0.09}$ (syst)$_{− 0.06}^{+ 0.07}$ (theo), which is largely insensitive to the exact Higgs mass around 125 GeV. Signal strengths associated with the different Higgs boson production mechanisms, couplings to bosons and fermions, and effective couplings to photons and gluons are also measured.

Emphysema and metalloelastase expression in mouse lung induced by cigarette smoke.

Abstract: Cigarette smoke (CS) causes pulmonary emphysema in humans and elastin degradation plays a key role in its pathogenesis. Previous studies on CS-exposed animals have been equivocal and have not clearly demonstrated the progression of the disease. In this study, morphometry was used to assess lung modifications to alveolar septa, airspaces, elastic and collagen fibers, and alveolar macrophages. Male (n = 40) C57/BL6 mice were exposed 3 times/day, whole body, to CS from three cigarettes for 10, 20, 30, or 60 days. Control groups (n = 10) were sham-smoked or received no exposure (day 0, n = 10). Morphometry included measurements of volume fraction of alveolar septa and airspaces, elastic and collagen fibers, and surface fraction of elastic fibers and alveolar septa. Morphometrical differences in mice after 60 days of exposure were greater than those after 10, 20, or 30 days, suggesting a progression of the disease. Inflammatory lesions in the lungs of mice contained significantly more metalloelastase (MMP-12) in macrophages at 10, 20, and 30 days than in controls of mice exposed for 60 days. These results suggest that elastin degradation took place during development of pulmonary changes in mice exposed to CS, and activation of MMPs specific for elastin may be a determining factor for susceptibility to emphysema.

Acolhimento e vínculo: práticas de integralidade na gestão do cuidado em saúde em grandes centros urbanos

Abstract: A estrategia da Saude da Familia e a principal proposta de reorganizacao do modelo de atencao a saude, sendo apoiada politico, institucional e economicamente pelo Estado, como alternativa de consolidacao dos principios do Sistema Unico de Saude. A expansao e implementacao dessa proposta, em grandes centros urbanos, tem encontrado dificuldades, tendo em vista a complexidade dos contextos sociais, politicos e economicos que envolvem as familias residentes nesses territorios, sendo objeto de discussao de diferentes especialistas no campo da Saude Coletiva. Este artigo faz uma analise dos usos e sentidos atribuidos aos termos integralidade, vinculo e acolhimento, no que concerne a gestao do cuidado em saude, identificando essas estrategias como elementos das praticas de saude em programas de atencao integral e da construcao do direito a saude como direito de cidadania.
