Nascidos vivos com fenda palatina e labial: estudo epidemiológico

Introduction: Cleft lip and palate is a congenital malformation resulting from the inadequate fusion of bony structures during embryonic development. The etiology is multifactorial, involving genetic and environmental factors. Methodology: This study constitutes a descriptive epidemiological analysis focusing on the investigation of cases of live births with cleft lip and palate in Brazil. Data collection will be conducted through the Live Birth Information System (SINASC) during the period from 2017 to 2021. Results: The gender distribution of live births with cleft lip and palate indicates a male predominance in the sample, representing approximately 58.49% (n=4,390) of the total. Meanwhile, the percentage of female individuals is approximately 41.01% (n=3,078). The category "Unknown" has a very small representation, accounting for only 0.51% (n=38) of the sample. Conclusion: It is observed that live births with cleft lip and palate should not be overlooked. There is a significant number of cases each year, necessitating further related studies to provide solutions in society that directly benefit those affected.Introdução: A fenda labial e palatina é uma malformação congênita resultante da não fusão das estruturas ósseas adequadas durante o desenvolvimento embrionário.

Avaliação de tubérculos de rabanete (Raphanus sativus) Brassicaceae submetidos a diferentes doses de Si (Plus, GigaMix®)

Silicon (Si) is the second most abundant element on Earth, being responsible for several benefits to plants, such as root development, aerial part, increase in photosynthetic rates and protection of plants against phytopathogens. The study aimed to evaluate different plant parameters in three radish cultivars (Long Scarlet Short Top “Long Red”, Comet and Round) at different doses of Silicon. Three varieties of radishes were used. Different doses of Si with 8% (g kg-1) were tested for shoot and tuber development. The results showed that both the control and the Si dosages were not significant for the parameters number of leaves and fresh and dry mass of the shoot. As for the tuber diameter and weight parameters in the three cultivars, the response doses were significant even at the lowest concentration of 13.5 g kg-1 and maximum performance at the highest concentration of 75 g kg-1, except for the Comet variety that presented greater weight in the intermediate concentration of 53.5 g kg-1 with 17.83 g. The response doses containing 8% of Si in the evaluated formula showed, in this study, excellent suitability for use applied directly in the soil on the three radish cultivars with a significant increase on the variable diameter and fresh weight.El silicio (Si) es el segundo elemento más abundante en la Tierra, responsable de varios beneficios para las plantas, como el desarrollo de las raíces, la parte aérea, el aumento de las tasas fotosintéticas y la protección de las plantas contra los fitopatógenos. El estudio tuvo como objetivo evaluar diferentes parámetros vegetales en tres cultivares de rábano (Vermelho Comprido, Cometa y Redondo) a diferentes dosis de Silicio. Se utilizaron tres variedades de rábanos. Se probaron diferentes dosis de Si al 8% (g kg-1) para el desarrollo de brotes y tubérculos. Los resultados mostraron que tanto el control como las dosis de Si no fueron significativas para los parámetros número de hojas y masa fresca y seca del brote. En cuanto a los parámetros de diámetro y peso del tubérculo en los tres cultivares, las dosis de respuesta fueron significativas incluso a la concentración más baja de 13,5 g kg-1 y el rendimiento máximo a la concentración más alta de 75 g kg-1, a excepción de la variedad Cometa que presentó mayor peso en la concentración intermedia de 53,5 g kg-1 con 17,83 g. Las dosis de respuesta que contenían 8% de Si en la fórmula evaluada mostraron, en este estudio, excelente idoneidad para el uso aplicado directamente en el suelo en los tres cultivares de rábano con un aumento significativo en las variables diámetro y peso fresco.O Silício (Si) é o segundo elemento com maior em abundância na Terra, sendo esse responsável por diversos benefícios aos vegetais, como desenvolvimento de raízes, parte aérea aumento nas taxas fotossintéticas e proteção de plantas contra fitopatógenos.

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
