Non-specific intraventricular conduction delay or atypical LBBB - How to predict acute coronary occlusion?

We describe two patient cases with acute coronary syndrome (ACS) and broad QRS in the acute phase electrocardiogram (ECG). The patients' ECG findings resembled left bundle branch block (LBBB), but with atypical features. Broad QRS not fulfilling the criteria for LBBB or right bundle branch block (RBBB) is diagnosed as non-specific intraventricular conduction delay (NSIVCD). The case report deals with the challenges of predicting acute coronary occlusion in patients with NSIVCD in their acute phase ECG. In one of the cases, the ECG changed from typical LBBB to NSIVCD or atypical LBBB with the development of systolic dysfunction and clinical heart failure.publishedVersionPeer reviewe

IRRIGAÇÃO SUPLEMENTAR NA PRODUÇÃO DE GRÃOS E NA EFICIÊNCIA DE USO DA ÁGUA DA CULTURA DO FEIJOEIRO

A água é um dos principais fatores climáticos que limitam a produção de feijão vindo a somar com outros fatores como temperatura e radiação solar. Assim, o uso de irrigação é um importante aliado em regiões onde ocorrem grandes irregularidades de precipitações pluviais. Deste modo objetivou-se analisar o efeito de lâmina de irrigação suplementar na produção de grãos da cultura do feijão, bem como a eficiência de uso da água, na região Fronteira Oeste do Estado do Rio Grande do Sul. O experimento foi conduzido em área experimental do curso de Engenharia Agrícola, da Universidade Federal do Pampa/Alegrete, RS. A cultura foi semeada em janeiro de 2013, em sistema de plantio direto. Para condução das irrigações, foi utilizado um sistema de aspersão convencional, sendo o momento das irrigações definido com base no turno de rega pré-fixado, e a quantidade de água pelo cálculo da evapotranspiração da cultura (ETc). Os tratamentos foram: T1 - precipitação pluviométrica, T2 - Reposição de 46% da ETc, T3 - Reposição de 73% da ETc, T4 - Reposição de 84% da ETc e T5 - Reposição de 100% da ETc. Avaliou-se: número de vagens por planta, número de grãos por vagem, peso médio do grão, produção de grãos e eficiência do uso da água. O tratamento com reposição de 100% da ETc apresentou a maior produção de grãos (kg.ha-1), deferindo estatisticamente do demais. O mesmo comportamento foi observado para a eficiência do uso da água

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
