Are Patients with Polycystic Ovarian Syndrome Ideal Candidates for Oocyte Donation?

Background. The use of donated oocytes for in vitro fertilization treatment in patients with ovarian failure is universally recognized. But would patients with polycystic ovarian syndrome (PCOS) be a good choice for egg donation programs? Objective. Comparing the pregnancy rates of egg receptors from donor patients diagnosed with PCOS to receptors from donors without PCOS. Design. Retrospective cohort study. Methods. A total of 234 patients who had undergone egg reception program were separated into two groups: Group I, receptors from PCOS donors ( = 36); Group II, receptors from donors without PCOS ( = 198). Medical records were reviewed and the fertilization, implantation, and pregnancy rates were calculated. Results. PCOS patients had an average of 3.23 more oocytes retrieved, but there were no differences in the number of mature oocytes that were used for donation between the groups. We also observed that the number of transferred embryos was also not significantly different, as well as the fertilization and implantation rates. The clinical pregnancy rates were not significantly different: 28% and 26% in Group I and Group II, respectively. Conclusions. Women with PCOS should not be excluded from egg donation programs

Efeito de doses de N-P-K sobre as características agronômicas do abacaxizeiro

Fertilization is a major factor in the management of any crop, in pineapple culture it is responsible for providing higher quality fruits. In view of this, the objective of this work was to evaluate the effect of different doses of N-P-K on the quality of the pineapple fruit. The experiment was carried out in DBC and tested 5 treatments with increasing doses of NPK (0, 18, 36, 54 and 72 g / plant), the variables analyzed were: fruit mass, fruit circumference, fruit length, crown mass, crown length, and SST. The values ​​obtained were subjected to analysis of variance and regression test. The increase in fertilizer doses in the pineapple culture promoted greater fruit development, where maximum fruit mass productivity was obtained with application of 72g of the fertilizer formulated per plant.A adubação é um fator primordial na condução de qualquer lavoura, na cultura do abacaxi é responsável por propiciar frutos de maior qualidade. Diante disto, o objetivo deste trabalho foi avaliar o efeito de diferentes doses de N-P-K sobre a qualidade do fruto do abacaxizeiro. O experimento foi realizado em DBC e testou 5 tratamentos com doses crescentes de N-P-K (0, 18, 36, 54 e 72 g/planta), as variáveis analisadas foram: massa do fruto, circunferência do fruto, comprimento do fruto, massa da coroa, comprimento da coroa, e SST. Os valores obtidos foram submetidos à analise de variância e ao teste de regressão. O aumento das doses de adubo na cultura do abacaxizeiro promoveu maior desenvolvimento do fruto, onde a máxima produtividade de massa do fruto foi obtida com aplicação de 72g do adubo formulado por planta

Fernando Pessoa, singularity, and world literature

Fernando Pessoa (1888–1935) wrote using a variety of heteronyms and is widely recognized as the most important Portuguese poet of the twentieth century. After a belated reception he can now be seen as a key figure in European modernism and in world literature. His fragmentary Book of Disquiet has been especially influential across various media. Pessoa's writing, directed to the future, is indicative of a modernity that is still in the process of coming

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

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
