The Gorutuba Formation: coastal to continental sedimentation on the eastern margin of Bambuí Basin (MG)

Propõe-se neste trabalho a formalização da Formação Gorutuba, unidade que engloba os únicos registros remanescentes de ambientes litorâneos e continentais da margem leste da Bacia Bambuí, desenvolvida durante a Orogênese Brasiliana. As rochas da Formação Gorutuba são reconhecíveis em três áreas principais. Nas serras da Jaíba e Colonial, a unidade apresenta um pacote basal de brecha composta por clastos de calcário imersos em matriz arcoseana, que indicam o retrabalhamento do calcário da Formação Jaíba, subjacente. Arcósio ocorre na forma de lentes e camadas intercaladas na brecha, tornando-se predominante em direção ao topo da unidade, onde ocorrem corpos isolados de ortoconglomerado. Na Serra do Gorutuba, a unidade apresenta o mesmo arranjo estratigráfico, porém assenta-se diretamente sobre siltito da Formação Serra da Saudade. No Sinclinal de Buenópolis, por sua vez, arenitos arcoseanos com estratificações cruzadas acanaladas e eventuais lentes de conglomerado e pelito assentam-se sobre siltito da Formação Serra da Saudade, não ocorrendo a brecha basal. A Formação Gorutuba registra um período de soerguimento, exposição e erosão da extensa plataforma marinha representada pelo Grupo Bambuí. A brecha basal, que ocorre nas áreas mais a norte, registra importante discordância erosiva, associada ao retrabalhamento por ondas da plataforma carbonática Jaíba, cujo soerguimento se relaciona à intensa atividade tectônica do período. O aumento da contribuição siliciclástica para o topo está associado à progressiva instalação de um sistema fluvial de alta energia, que marca a fase de colmatação da bacia. A composição dos sedimentos siliciclásticos presentes na matriz da brecha e no restante da unidade sugere a exumação de fontes graníticas no Orógeno Araçuaí.In this study, we formally introduce the Gorutuba Formation, unit that encompasses the remaining coastal and continental records of the eastern margin of the Bambuí Basin, evolved during the Brasiliano/Pan-Africano Orogeny. In Minas Gerais, the Gorutuba Formation occurs in three main localities. In Jaíba and Colonial ridges, the unit shows a basal layer of breccia composed by clasts of limestone in arcosean matrix, recording the erosion and reworking of the underlying Jaíba Formation. Arcose occurs as layers and lenses within the breccia, and becomes the main rock to the top, where shows some lenses of ortoconglomerate. In Gorutuba and Rompe Gibão ridges, the unit shows the same stratigraphic pattern, but lies on the Serra da Saudade siltstones. In Buenópolis Sincline, on the other hand, arcosean sandstone with through cross stratification and conglomerate lenses lie on siltstones from Serra da Saudade Formation, lacking the basal breccia. The Gorutuba Formation records an uplift, exposure and erosion stage of the wide Bambuí marine platform. The basal breccia, which occurs in the northernmost areas, records an important unconformity, where the Jaíba carbonatic shelf was reworked by waves in response to the tectonic driven uplift. The increase of the sandstones to the top is associated to the gradual installation of a high-energy fluvial system, marking the clogging stage of the basin. The composition of the sandstones and the breccia’s matrix suggests the exhumation of granitic sources in the Araçuaí Orogen in this period

Cultura de segurança do doente pediátrico

Introdução: A cultura de segurança consiste num conjunto de valores individuais e de grupo, de atitudes, percepções, competências e padrões de comportamento que determinam o compromisso com a segurança. Ao conhecer a cultura de segurança do serviço e organização é possível identificar pontos fortes, assim como aspectos problemáticos, devendo estes ser encarados como oportunidades para melhorar. Embora se acredite que é essencial investir no desenvolvimento de uma cultura de segurança sólida e positiva, os estudos realizados neste âmbito em contexto pediátrico são praticamente inexistentes. Objectivo: O objectivo geral consiste em avaliar a cultura de segurança do doente pediátrico percepcionada pelos profissionais de saúde, identificando assim áreas de intervenção prioritária em prol da segurança e qualidade dos cuidados prestados. Metodologia: Estudo quantitativo, de cariz descritivo-correlacional. A amostra é constituída por 167 profissionais de saúde do Centro Hospitalar e Universitário de Coimbra. O instrumento utilizado baseia-se no Hospital Survey on Patient Safety Culture, traduzido e validado para a população portuguesa. Resultados: Dos resultados, salienta-se a dimensão “trabalho em equipa” que obteve isoladamente o valor mais positivo. As dimensões consideradas problemáticas são: “apoio à segurança pela gestão”, “frequência da notificação de eventos”, “profissionais” e “resposta ao erro não punitiva”, devendo ser merecedoras de intervenção prioritária. A percepção de cultura de segurança do doente pediátrico é influenciada pelas variáveis sociodemográficas e pela profissão. Constata-se ainda que uma grande maioria dos profissionais (79.6%) não notificou eventos/ocorrências nos últimos meses e que 63.5% nunca o realizou ao longo da sua vida profissional. Conclusões: Estes dados sugerem ser necessário investir a curto prazo numa política de segurança que promova a notificação voluntária e não punitiva de incidentes.Abstract Introduction: Safety culture is a set of individual and group values, attitudes, perceptions, competencies and patterns of behaviour that determine the commitment to safety. By knowing the service organization and safety culture is possible to identify strengths as well as areas of concern, which must be seen as opportunities to improve. Although it is believed that it is essential to invest in the development of a strong and positive safety culture, studies in this area in pediatric settings are virtually nonexistent. Objective: The overall objective is to evaluate the safety culture of the pediatric patient perceived by health professionals, therefore identifying priority areas of intervention for safety and quality of care. Methodology: Quantitative study of descriptive and correlational nature. The sample consists of 167 health professionals working in Coimbra University Hospital Center. The instrument used is based on the Hospital Survey on Patient Safety Culture, translated and validated for the Portuguese population. Results: The results highlight the dimension "teamwork" with the most positive value. Other dimensions are considered problematic, "hospital management support for patient safety", "frequency of event reporting", "staffing" and "non-punitive response to error" and should be worthy of priority intervention. The perception of the pediatric patient safety culture is influenced by sociodemographic variables and the profession. We also noted that a large majority of professionals (79.6%) did not report events/occurrences in recent months and 63.5% never held throughout his professional life. Conclusions: These data suggest a short-term need to invest in a security policy that promotes voluntary reporting and non-punitive incident

Cytotoxicity Assessment of Novel Cellulose Nanomaterials on Intestinal Cells

Cellulose nanomaterials (CNMs) emerged as an important group of nanomaterials with potential applications in multiple food-related products, as zero-calorie filler/thickener/stabilizer, or as a substitute for petroleum-based food packaging materials. Human oral exposure to CNMs is increasing, but little is known about the potential adverse biological impact of CNMs on human gastrointestinal tract. To contribute to the development of innovative CNMs for the food sector and to their early-stage safety assessment, in this work new CNMs were prepared, and their cytotoxic effects were investigated in human intestinal cell lines. Two cellulose micro/nanofibrillated (CNFs), were synthetized from industrial bleached Eucalyptus globulus kraft pulp using different pretreatments (enzymatic and TEMPO-mediated oxidation) followed by a high-pressure homogenization process. Potential cytotoxic effects were evaluated by the MTT assay using two human intestinal cell models (Caco-2 and HT29-MTX-E12). Since in humans the digestion process may modify the physicochemical properties of NMs, potentially influencing biological outcomes, the CNFs were subjected to a harmonized in vitro digestion method before cytotoxicity testing. No cytotoxic effect was observed after 24h exposure to the undigested CNFs in the concentration-range tested (3.1 µg/mL-200 µg/mL), irrespectively of the cell line used. Similar results were obtained for the digested CNFs for concentrations up to 14.3 µg/mL. The observation that the in vitro digestion mixture was cytotoxic by itself for concentrations above 7.6 % (v/v) (i.e., equivalent to CNMs exposure > 14.3 µg/mL) impaired cytotoxicity assessment at higher CNFs concentrations. Complementary cytotoxicity assays and future optimization of the in vitro digestion procedure to reduce its toxicity are underway, to refine the assessment of CNFs cytotoxicity, particularly after digestion. Furthermore, genotoxicity studies will increase the knowledge on the cellular effects of CNMs in the human intestine, contributing to the safety assessment of CNMs early in its development stage, towards sustainable innovation of nanomaterials, thereby protecting human health.FCT/MCTES through national funds (PTDC/SAU-PUB/29481/2017; PTDC/SAUPUB/ 32587/2017) and (UIDB/00009/2020; UIDP/00009/2020); FCT/MCTES PhD studentship 2020.07168.BD was attributed to NVinfo:eu-repo/semantics/publishedVersio

Towards an integrated tectonic model for the interaction between the Bambuí basin and the adjoining orogenic belts : evidences from the detrital zircon record of syn-orogenic units.

The Sao ̃ Francisco craton and its surrounding orogens are some of the most important tectonic elements of South America, and key regions to understanding the assembly of Western Gondwana in the Proterozoic-Palaeozoic transition. During this major tectonic event, diachronic collisions between small continents developed an intricated orogenic system, where several orogens evolved in unique paths through time and space. In such collisional settings, there are some tectonic processes that promote subsidence, thus controlling the formation of orogenic-related sedimentary basins. Furthermore, the tectonic activity in collisional orogens generates dynamic landscapes that usually favor increased erosion and sediment generation to feed these basins, making them key places to seek for clues about the tectonic evolution of their surroundings. On the S ̃ ao Francisco craton, the Bambuí Group records a complex foreland system, which evolved in response to the lithospheric overload exerted by the uplift of both Brasília belt and Araçuaí orogen. In turn, both Salinas Formation and Ibia ́ Group comprise orogenic deposits resting within the Araçuaí orogen and Brasília belt, respectively, whose tectonic significance is still under debate. Here we present new U–Pb (LA-ICP-MS and SHRIMP) and Lu–Hf isotopic an- alyses on a great amount of detrital zircon grains extracted from the rocks of the Bambuí Group and Salinas Formation, together with a thorough data compilation from the literature. The two units present similar prov- enance patterns, sharing the major detrital zircon age peaks (550–650 Ma, 950–1050 Ma, 1750–2000 Ma, 2600–2800 Ma) and maximum depositional age in c. 550 Ma. The Ediacaran zircons recovered from the Bambuí Group show a wide range of the εHf(t), ranging from c. − 17 to +15, which suggest the existence of multiple late Neoproterozoic sources, some of them juvenile and some with a long crustal residence. The variation in detrital zircon age patterns and εHf(t) values from different units within the Bambuí Group provided additional clues of provenance changes occurred during the evolution of the basin. The new data obtained for the Salinas Formation constrain its deposition between 548 and 500 Ma, which have an important implication on its tectonic signifi- cance. We propose that in both Brasília belt and Araçuaí orogen sides, the early foredeep deposits of the Bambuí basin should have been incorporated to the orogenic domains, which could explain the apparent lack of deposits recording the climax of the Brasilia belt uplift (c. 630 Ma) within the cratonic area. In this same direction, we consider that both Salinas Formation and Ibi ́ a Group could represent remnants of these early foreland deposits related to the uplift of Brasília belt and Araçuaí orogen, respectively, incorporated to the orogenic wedges due to the advance of the deformational fronts. Therefore, what we know as Bambuí Group is in fact the remaining record of an advanced stage of the foreland system, when subsidence was already influenced by the two evolving orogens. Altogether, the analyses of the stratigraphic, structural and geochronological data converge towards an integrated tectonic model for the interaction between the Bambuí basin and the surrounding orogens during West Gondwana amalgamation

The tomato genome sequence provides insights into fleshy fruit evolution

Tomato (Solanum lycopersicum) is a major crop plant and a model system for fruit development. Solanum is one of the largest angiosperm genera1 and includes annual and perennial plants from diverse habitats. Here we present a high-quality genome sequence of domesticated tomato, a draft sequence of its closest wild relative, Solanum pimpinellifolium2, and compare them to each other and to the potato genome (Solanum tuberosum). The two tomato genomes show only 0.6% nucleotide divergence and signs of recent admixture, but show more than 8% divergence from potato, with nine large and several smaller inversions. In contrast to Arabidopsis, but similar to soybean, tomato and potato small RNAs map predominantly to gene-rich chromosomal regions, including gene promoters. The Solanum lineage has experienced two consecutive genome triplications: one that is ancient and shared with rosids, and a more recent one. These triplications set the stage for the neofunctionalization of genes controlling fruit characteristics, such as colour and fleshiness
