BACKGROUND The Memórias do Instituto Oswaldo Cruz (MIOC) is one of the first scientific journals created in Brazil and currently one of the most important biomedical journals in South America. Knowledge of the main themes disseminated over time and its main contributors can contribute towards a better understanding of its trajectory and future. OBJECTIVES Map the journal’s scientific publication between 1909 and 2020. METHODS Data from three scientific databases was combined, alongside bibliometrics and network analysis to analyse publication records between 1909 and 2020. FINDINGS Publications increased substantially since the 1980s. The main publishing organisations are Brazilian. Excluding Brazil, the main publishing countries are the USA, Argentina, and Colombia. During the entire investigated period, the main themes refer to Chagas disease, schistosomiasis, and Leishmaniasis. During some periods, publications followed disease outbreaks in Brazil (e.g., dengue fever and yellow fever). MAIN CONCLUSIONS Since its foundation in 1909, the MIOC has focused on infectious and parasitic diseases. The editorial changes implemented from the 1980s onwards led MIOC to a relevant growth concerning annual publications and its transformation into an important communication vehicle for researchers from several Brazilian organisations besides Fiocruz, as well as organisations from other countries, especially within Latin America.

BACKGROUND The five BRICS (Brazil, Russian, Indian, China, and South Africa) countries bear 49% of the world’s tuberculosis (TB) burden and they are committed to ending tuberculosis. OBJECTIVES The aim of this paper is to map the scientific landscape related to TB research in BRICS countries. METHODS Were combined bibliometrics and social network analysis techniques to map the scientific publications related to TB produced by the BRICS. Was made a descriptive statistical data covering the full period of analysis (1993-2016) and the research networks were made for 2007-2016 (8,366 records). The bubble charts were generated by VantagePoint and the networks by the Gephi 0.9.1 software (Gephi Consortium 2010) from co-occurrence matrices produced in VantagePoint. The Fruchterman-Reingold algorithm provided the networks’ layout. FINDINGS During the period 1993-2016, there were 38,315 peer-reviewed, among them, there were 11,018 (28.7%) articles related by one or more authors in a BRICS: India 38.7%; China 23.8%; South Africa 21.1%; Brazil 13.0%; and Russia 4.5% (The total was greater than 100% because our criterion was all papers with at least one author in a BRICS). Among the BRICS, there was greater interaction between India and South Africa and organisations in India and China had the highest productivity; however, South African organisations had more interaction with countries outside the BRICS. Publications by and about BRICS generally covered all research areas, especially those in India and China covered all research areas, although Brazil and South Africa prioritised infectious diseases, microbiology, and the respiratory system. MAIN CONCLUSIONS An overview of BRICS scientific publications and interactions highlighted the necessity to develop a BRICS TB research plan to increase efforts and funding to ensure that basic science research successfully translates into products and policies to help end the TB epidemic.

O trabalho teve como objetivo avaliar o efeito de diferentes embalagens e ambientes de armazenamento na manutenção da qualidade fisiológica de sementes de Erythrina velutina Willd.. O experimento foi conduzido no Laboratório de Análise de Sementes do Departamento de Fitotecnia do Centro de Ciências Agrárias da Universidade Federal da Paraíba (CCA-UFPB), localizado no município de Areia (PB). As sementes de Erythrina velutina Willd. foram coletadas embaixo de árvores matrizes, no mesmo município e levadas para o laboratório, onde se realizou a homogeneização e acondicionamento em embalagens de papel, pano e vidro e, posterior armazenamento em condições não controladas de laboratório (±25ºC), geladeira (6 ± 2ºC) e câmara fria (4 ± 2ºC), por um período de 225 dias. Antes e após os intervalos de 45 dias foram retiradas amostras de cada embalagem e ambiente de armazenamento para avaliação das seguintes características: teor de água, emergência (porcentagem e índice de velocidade), comprimento e massa seca de epicótilo, hipocótilo e raiz das plântulas normais. O delineamento experimental utilizado foi inteiramente ao acaso com quatro repetições de 25 sementes para cada teste. As sementes de mulungu são ortodoxas e acondicionando-as nas embalagens de papel, pano ou vidro podem ser armazenadas nos ambientes de laboratório, geladeira e câmara fria, durante 225 dias sem perdas significativas na emergência das plântulas.

The objective of this experiment was to evaluate the effect of different packages and storage environments in maintainace of physiological quality of Erythrina velutina Willd seeds. The experiment was carried out in the Laboratory of Seed Analysis of Seeds in Department of Phytotecny in the Center of Agriculture Sciences at Federal University of Paraíba (CCA-UFPB), located in Areia, northeastern Brazil. The seeds of Erythrina velutina were collected under the matrix trees in the same city and taken to the laboratory, where it was carried out homogenization and packing in paper, cloth and glass packages and, posterior storage in non-controlled laboratory conditions (±25ºC), refrigerator (6± 2ºC) and cold chamber (4 ± 2ºC), for a period of 225 days. Before and after the 45- day intervals, samples were removed from each package and storage environment for evaluation of the following characteristics: water content, emergency test (percentage and speed rate); length and dry mass of epicotyle, hipocotyle and root of normal seedlings. The experimental design used was completely randomized with four replicates of 25 seeds for each test. E. velutina seeds are orthodox and by packing them in paper, cloth or glass packages, they can be stored in environments of laboratory, refrigerator and cold chamber for 225 days without significant loss in seedling emergency.
