| Abstract MicroRNAs (miRNAs) play an essential role in gene expression and affect the development of tumours, including breast cancer (BC). Polymorphisms in miRNA genes can affect the interaction of miRNAs with their target messenger RNA by interfering, creating or disrupting target sites. The single nucleotide polymorphism (SNP) rs2910164, located in the seed region of miR146a, was shown to be associated with BC among different populations. In the present study, we investigated whether rs2910164 is associated with BC in 326 patients and 411 controls from a Brazilian population of predominantly European ancestry. The presence of the allele rs2910164*C was associated with an increased risk of BC (OR=1.4, 95% CI=1.03-1.85, p = 0.03). We also analysed publicly... |

| ABSTRACT Body-size is significantly correlated with the number of vertebrae (pleomerism) in multiple vertebrate lineages, indicating that somitogenesis process is an important factor dictating evolutionary change associated to phyletic allometry and, consequently, species fitness and diversification. However, the role of the evolution of extreme body sizes (dwarfism and gigantism) remains elusive in snakes, mainly with respect to postnatal ontogeny in dietary preferences associated with evolution of gigantism in many lineages. We described herein a new species in the highly diversified and species-rich genus Atractus on the basis of four specimens from the southeastern slopes of the Ecuadorian Andes. The new species is morphologically similar and... |

| Light emerging from natural water bodies and measured by remote sensing radiometers contains information about the local type and concentrations of phytoplankton, non-algal particles and colored dissolved organic matter in the underlying waters. An increase in spectral resolution in forthcoming satellite and airborne remote sensing missions is expected to lead to new or improved capabilities to characterize aquatic ecosystems. Such upcoming missions include NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Mission; the NASA Surface Biology and Geology observable mission; and NASA Airborne Visible/Infrared Imaging Spectrometer – Next Generation (AVIRIS-NG) airborne missions. In anticipation of these missions, we present an organized dataset of... |

| Plankton are the base of marine food webs, essential to sustaining fisheries and other marine life. Continuous Plankton Recorders (CPRs) have sampled plankton for decades in both hemispheres and several regional seas. CPR research has been integral to advancing understanding of plankton dynamics and informing policy and management decisions. We describe how the CPR can contribute to global plankton diversity monitoring, being cost-effective over large scales and providing taxonomically resolved data. At OceanObs09 an integrated network of regional CPR surveys was envisaged and in 2011 the existing surveys formed the Global Alliance of CPR Surveys (GACS). GAGS first focused on strengthening the dataset by identifying and documenting CPR best practices,... |

| Abstract The aim of this study was to investigate in vitro antioxidant properties and in vivo protective effects of the methanol extract of the Hypericum triquetrifolium Turra (HT) seed against acute hepatotoxicity, myelotoxicity and hematotoxicity in rats induced by cyclophosphamide (CP). In order to investigate in vivo protective effects of the HT extract on rat tissues, the rats were divided into nine groups. The toxic effects of CP and the protective effects of HT extract on nucleated cells that are produced by bone marrow, serum alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and oxidative stress index (OSI) levels were investigated biochemically. Additionally, liver tissue samples were examined for... |

| No projeto Hortas Pedagógicas, o nutricionista tem um papel estratégico: fazer a conexão entre a horta e a cozinha. Sugerimos que você acompanhe a escolha das hortaliças e frutas a serem cultivadas na horta e planeje os cardápios de acordo com a produção que sai dos canteiros. Você também pode contribuir para que os professores levem a horta para dentro da sala de aula, fornecendo informações e conhecimentos sobre a importância de uma alimentação saudável e nutritiva. Para ajudá-lo nessas tarefas, elaboramos este planner com orientações essenciais para apoiar a execução do programa de alimentação escolar do seu município, incluindo mais alimentos naturais e nutritivos que podem ser produzidos na própria horta escolar ou na comunidade. |

| Abstract: The West Indian (Trichechus manatus) and Amazonian (T. inunguis) manatees have a sympatric occurrence at the mouth of the Amazon River. A result of this interspecific encounter is the occurrence of hybrids, which are frequently found along the coasts of Amapá state in Brazil, French Guiana and Guyana. Here we present new genetic evidence indicating the occurrence of a hybrid swarm along the Guianas Shield coastline, which is an interspecific hybrid zone that also separates T. manatus populations located east (Brazil) and west (Caribbean, Gulf of Mexico, Florida and Antilles). In addition, we suggest that this hybrid population occupies a peculiar mangrove-rich environment under strong influence of the Amazon River plume, which requires an... |

| Esta nota técnica tem como objetivo relatar os problemas com a introdução da tilápia-do-nilo Oreochromis niloticus, um peixe da família dos ciclídeos originário do delta do Rio Nilo (leste da África), que tem ampla disseminação em diversos países das regiões tropicais e subtropicais do planeta (Canônico et al., 2005; Carvalho, 2006; Singh; Lakra, 2011; Gu et al., 2015; Padial et al., 2017). Essa disseminação foi iniciada com o objetivo de promover o seu cultivo para subsistência de populações carentes de países em desenvolvimento (Lovshin, 1997; Canônico et al., 2005). |

| The Sentinel‐1 mission is part of the European Copernicus program aiming at providing observations for Land, Marine and Atmosphere Monitoring, Emergency Management, Security and Climate Change. It is a constellation of two (Sentinel‐1 A and B) Synthetic Aperture Radar (SAR) satellites. The SAR wave mode (WV) routinely collects high‐resolution SAR images of the ocean surface during day and night and through clouds. In this study, a subset of more than 37,000 SAR images is labelled corresponding to ten geophysical phenomena, including both oceanic and meteorologic features. These images cover the entire open ocean and are manually selected from Sentinel‐1A WV acquisitions in 2016. For each image, only one prevalent geophysical phenomenon with its prescribed... |
