Global, regional, and national incidence, prevalence, and years lived with disability for 328 diseases and injuries for 195 countries, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016

As mortality rates decline, life expectancy increases, and populations age, non-fatal outcomes of diseases and injuries are becoming a larger component of the global burden of disease. The Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) provides a comprehensive assessment of prevalence, incidence, and years lived with disability (YLDs) for 328 causes in 195 countries and territories from 1990 to 2016

The potent anti-cancer activity of Dioclea lasiocarpa lectin

The lectin DLasiL was isolated from seeds of the Dioclea lasiocarpa collected from the northeast coast of Brazil and characterized for the first time by mass spectrometry, DNA sequencing, inductively coupled plasma-mass spectrometry, electron paramagnetic resonance, and fluorescence spectroscopy. The structure of DLasiL lectin obtained by homology modelling suggested strong conservation of the dinuclear Ca/Mn and sugar-binding sites, and dependence of the solvent accessibility of tryptophan-88 on the oligomerisation state of the protein. DLasiL showed highly potent (low nanomolar) antiproliferative activity against several human carcinoma cell lines including A2780 (ovarian), A549 (lung), MCF-7 (breast) and PC3 (prostate), and was as, or more, potent than the lectins ConBr (Canavalia brasiliensis), ConM (Canavalia maritima) and DSclerL (Dioclea sclerocarpa) against A2780 and PC3 cells. Interestingly, DLasiL lectin caused a G2/M arrest in A2780 cells after 24 h exposure, activating caspase 9 and delaying the on-set of apoptosis. Confocal microscopy showed that fluorescently-labelled DLasiL localized around the nuclei of A2780 cells at lectin doses of 0.5–2 × IC50 and gave rise to enlarged nuclei and spreading of the cells at high doses. These data reveal the interesting antiproliferative activity of DLasiL lectin, and suggest that further investigations to explore the potential of DLasiL as a new anticancer agent are warranted

Desempenho e histomorfometria intestinal de frangos de corte de 1 a 21 dias de idade recebendo melhoradores de crescimento Performance and intestinal histomorphometry of broiler chickens at 1 to 21 days of age fed growth promoters

Esta pesquisa foi desenvolvida para avaliar o desempenho produtivo e a histomorfometria dos segmentos do intestino delgado em frangos de corte no período de 1 a 21 dias de idade alimentados com dietas contendo diferentes aditivos melhoradores de crescimento: ração controle (sem melhorador de crescimento); ração controle + antibióticos (colistina e bacitracina de zinco); ração controle + probiótico; ração controle + prebiótico; ração controle + probiótico + prebiótico. As aves foram distribuídas em delineamento em blocos casualizados, com cinco tratamentos e quatro repetições. Foram avaliadas as variáveis de desempenho, consumo de ração, ganho de peso e conversão alimentar e as características morfométricas, altura, perímetro e profundidade de vilos, dos segmentos do intestino delgado no período de 1 a 21 dias de idade. O desempenho das aves e as características morfométricas dos segmentos dos intestino não apresentaram diferença entre os grupos. O uso de probiótico, prebiótico, probiótico + prebiótico e antibiótico em rações para frangos de corte no período de 1 a 21 dias de idade em condições de baixo desafio sanitário não interfere no desempenho e nas características histomorfométricas dos segmentos do intestino delgado.<br>The objective of this work was to evaluate the performance and intestinal histomorphometry of small intestine segments in broiler chickens in 1 to 21-day of age period, fed diets with different growth promoter additives: control diet (without growth promoter); control diet + antibiotic (colistin and zinc bacitracin); control diet + probiotic (Protexin); control diet + prebiotic (Bio moss); control diet + probiotic + prebiotic. The birds were distributed in a random block design, with five treatments and four replications. It was evaluated variables of performance, feed intake, weight gain and feed conversion and the morphometric characteristics, height, circumference and depth of the villus of small intestine segments in 1 to 21-day of age period. Performance and morphometric traits of small intestine did not present differences among groups. The use of probiotic, prebiotic, probiotic + prebiotic and antibiotic in diets for broiler chickens in 1 to 21-day of age period, in conditions of low health challenge, does not interfere in the performance and in the histomorphometric characteristics of the segments of the small intestine

Measurement of the Higgs boson inclusive and differential fiducial production cross sections in the diphoton decay channel with pp collisions at s \sqrt{s} = 13 TeV

International audienceThe measurements of the inclusive and differential fiducial cross sections of the Higgs boson decaying to a pair of photons are presented. The analysis is performed using proton-proton collisions data recorded with the CMS detector at the LHC at a centre-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 137 fb$^{−1}$. The inclusive fiducial cross section is measured to be ${\sigma}_{\textrm{fid}}={73.4}_{-5.3}^{+5.4}{\left(\textrm{stat}\right)}_{-2.2}^{+2.4}\left(\textrm{syst}\right)$ fb, in agreement with the standard model expectation of 75.4 ± 4.1 fb. The measurements are also performed in fiducial regions targeting different production modes and as function of several observables describing the diphoton system, the number of additional jets present in the event, and other kinematic observables. Two double differential measurements are performed. No significant deviations from the standard model expectations are observed.[graphic not available: see fulltext
