A influência da monitoria no desempenho do discente no módulo de nutrição da concepção ao 2º ano de vida / The influence of monitoring on the performance of the disciple in the nutrition module of the concept to the 2 nd year of life

Analisar a presença do discente do curso de Nutrição nos encontros de monitoria do módulo de Nutrição da Concepção ao 2º Ano de Vida e o seu desempenho no decorrer do semestre 2017.1. Observou-se que, dos 96 estudantes matriculados, 19,79% passaram a ir ou aumentaram o número de presenças, apresentando melhora na média de NP2 em relação à média de NP1, e 23,95%, que continuaram a frequentar, alcançaram a uma nota superior à anterior ou maior ou igual a 8,0 na NP2, resultando, assim, em 43,74% de alunos com melhora em suas médias ou manutenção de suas boas notas. Apenas 2,08% deixaram de frequentar ou reduziram a presença aos encontros de monitoria, com uma diminuição na média de NP2. Houve correlação fraca, porém positiva e significativa (p = 0,009), apresentando uma correlação entre a variação das notas de NP1 e NP2 e a variação das presenças nas monitorias, sugerindo que alunos que aumentam a frequência nas monitorias obtêm um maior desempenho em suas médias

Aberrant levels of Wnt/β-catenin pathway components in a rat model of endometriosis

Endometriosis is a benign gynecological disease affecting approximately 10-15% of women of reproductive age and 25-50% of all infertile women. It is characterized by the presence of glands and/or endometrial stroma outside the uterine cavity. Angiogenesis is a crucial process for the development and maintenance of endometriotic lesions. The Wnt/βcatenin pathway is a major promoter of angiogenesis in both physiological and pathological conditions. In the present study, we evaluated the expression of molecules related to the Wnt/β-catenin pathway in a rat model of peritoneal endometriosis. mRNA analyses showed significantly increased expression of Wnt4 and Wnt7b and decreased expression of Gsk3beta and E-cadherin in endometriotic lesions. However, there were no differences in β-catenin and Fzd2 mRNA expression. In addition, we observed a significant increase of nuclear β-catenin in endometriotic lesions, a hallmark of Wnt/ β -catenin pathway activation. Stromal β-catenin staining was found in 45.4% of endometrial tissues and 77.8% of endometriotic lesions. β-catenin nuclear localization was found in 18.2% of the endometrial tissues and 33.3% of endometriotic lesions. Finally, the expression of galectin-3, a regulator of this pathway, was increased in endometriosis. In summary, this pattern of Wnt/βcatenin components expression suggests an increased activity of this pathway in endometriosis

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

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
