Resumo Bioestimulantes como extrato de algas podem ser fortes aliados na formação plugs de gramados, pois auxilia em diversos processos fisiológicos na planta. Ao mesmo tempo, a poda das folhas é o principal fator no custo de manutenção, existindo a procura por alternativas ao manejo mecânico sem prejudicar a qualidade estética, como o uso de reguladores de crescimento (RC). Assim, objetivou-se com esse experimento avaliar o uso de Ascophyllum nodosum na produção de mudas de gramas, e reguladores de crescimento no desenvolvimento da grama São Carlos. O experimento foi realizado entre 2020 e 2021, e dividido em duas partes, sendo a primeira a produção de mudas (30 dias) de grama Esmeralda, Bermuda DiscoveryTM, São Carlos e Batatais com aplicação do extrato de alga, na segunda parte avaliou-se o desenvolvimento da grama São Carlos após aplicação de RC (Trinexapac-ethy, Paclobutazol e Glifosato) em 60 dias. As avaliações realizadas foram: índice de cor verde (ICV); índice de vegetação por diferença normalizada (NDVI); comprimento da raiz e massa seca das mudas. E para a segunda parte: ICV; SPAD; NDVI; aspecto visual; taxa de cobertura; altura do gramado; taxa de crescimento e massa seca das aparas. Observou-se que o uso do bioestimulante incrementou a produção de plugs de gramados ornamentais, onde melhores valores puderam ser observados para a grama São Carlos. Já os RC demonstraram resultados eficientes para o controle da altura da grama São Carlos em até 30 dias, com destaque para o Trinexapac-ethy, que reduziu o crescimento e manteve a estética do gramado. planta tempo manutenção RC. .

Abstract Biostimulants such as seaweed extract can be strong allies in the formation of lawn plugs, as they assist in several physiological processes in the plant. At the same time, shoot mowing is the main factor in the maintenance cost of turfgrasses, and there is a search for alternatives to mechanical management without compromising aesthetic quality, such as the use of plant growth regulators (PGR). Thus, the objective of this experiment was to evaluate the use of Ascophyllum nodosum in the production of lawn seedlings, and growth regulators in the development of Carpet grass. The experiment was carried out between 2020 and 2021, and divided into two parts, the first being the production of seedlings (30 days) of Emerald grass, Bermudagrass DiscoveryTM, Carpet grass and Bahiagrass with the application of seaweed extract, in the second part the development of Carpet grass was evaluated after the application of PGRs (Trinexapac-ethy, Paclobutazol and Glyphosate) in 60 days. The evaluations performed were: green color index (GCI); normalized difference vegetation index (NDVI); root length and dry mass of seedlings. And for the second part: GCI; SPAD; NDVI; visual appearance; coverage rate; shoot height; growth rate and dry mass of clippings. It was observed that the use of the biostimulant increased the production of ornamental lawn plugs, where better values could be observed for Carpet grass. PGRs demonstrated efficient results for controlling the height of Carpet grass in up to 30 days, with emphasis on Trinexapac-ethyl, which reduced growth and maintained the aesthetics of the lawn. plugs time turfgrasses quality PGR.

Resumo O uso de extratos de bactérias e algas marinhas como bioestimulantes para promover o crescimento das plantas apresenta potencial para o manejo sustentável em áreas de produção de grama. Este estudo teve como objetivo investigar os efeitos da aplicação no solo do Azospirillum brasilense (bactéria) e do extrato de Ascophyllum nodosum (alga marinha) no crescimento inicial do capim bermuda DiscoveryTM. O estudo foi conduzido usando um desenho completamente aleatório com parcelas de 0,25 m², com bordas de 0,5 m. Foram realizados dois experimentos separados, cada um envolvendo quatro doses de bioestimulantes e cinco repetições. Os tratamentos com bioestimulantes consistiram em 0, 2, 4 e 6 mL L¹ de inoculante de A. brasilense e 0, 5, 10 e 15 mL L¹ de extrato de alga marinha A. nodosum. Os tratamentos foram aplicados uniformemente no solo (100 mL m²), com aplicações feitas 0, 30 e 60 dias após o início do experimento. Após 90 dias, foram avaliados os parâmetros índice de cor verde, taxa de cobertura verde, altura do gramado e índice de vegetação (diferença normalizada). Os resultados mostraram que os bioestimulantes promoveram o crescimento inicial da grama DiscoveryTM. Houve aumento da biomassa e melhor desenvolvimento do gramado, à medida que aumentavam as doses dos bioestimulantes. As respostas mais significativas foram observadas com a dose de 6 mL L-1 do inoculante bacteriano e 15 mL L-1 do extrato de algas marinhas. Os bioestimulantes promoveram melhor fechamento do gramado, dificultando o aparecimento de ervas daninhas e possivelmente acelerando a produção de grama. bactéria (bactéria DiscoveryTM 025 0 25 0,2 m² m 05 5 separados repetições 2 L A 1 100 (10 , m²) 3 experimento 9 verde diferença normalizada. normalizada . normalizada) L1 L- 02 (1 (

Abstract The use of bacteria and seaweed extracts as biostimulants to enhance plant growth holds promise for sustainable turfgrass management. This study aimed to investigate the effects of soil application of Azospirillum brasilense (bacterium) and Ascophyllum nodosum (seaweed) extract on the initial growth of DiscoveryTM bermudagrass. The study was conducted using a completely randomized design with plots measuring 0.25 m², each with a 0.5 m border. Two separate experiments were conducted, each involving four doses of biostimulants and five repetitions. The biostimulant treatments consisted of 0, 2, 4, and 6 mL L¹ A. brasilense inoculant and 0, 5, 10, and 15 mL L¹ A. nodosum seaweed extract. These treatments were uniformly applied to the soil at a rate of 100 mL m², with applications at 0, 30, and 60 days after the start of the experiment. After 90 days, the parameters green color index, green cover rate, turfgrass height, and vegetation index (normalized difference), were evaluated. The results indicated that both biostimulants significantly promoted the initial growth of DiscoveryTM bermudagrass. As the doses of the biostimulants increased, there was a corresponding increase in biomass and improved development of the turfgrass. The most pronounced responses were observed with a dose of 6 mL L¹ of the bacteria inoculant and 15 mL L¹ of the seaweed extract. These biostimulants fostered better turf coverage, making it challenging for weeds to establish, and potentially accelerating the production of sod grass. management bacterium (bacterium (seaweed bermudagrass 025 0 25 0.2 m² 05 5 0. border repetitions 2 4 L A 10 1 30 experiment 9 height normalized difference, difference , difference) evaluated increased coverage establish grass 02 3

ABSTRACT Tifway 419 Bermudagrass is widely used on athletic fields, requiring irrigation and fertilization for its maintenance; however, little information is available for Bermudagrass management in tropical countries, as Brazil. Thus, this study aimed to evaluate the effect of irrigation frequency and nitrogen (N) fertilization on the development of Tifway 419 Bermudagrass. The experiment was carried in 2019, applying two irrigation frequencies (daily and every two days) and five N concentrations of 0, 42.19, 63.28, 105.47 and 126.56 kg N ha-1 divided into three 30-day increments. Photosynthetic pigments, grass height, accumulated dry mass, relative chlorophyll index, regeneration rate, root length, and dry mass of root, rhizome and stolon were analyzed. The best result was observed in between 63.28 and 105.47 kg N ha-1 (15% N) and irrigated every two days. The treatment maintains the green color of the grass. Maximum Bermudagrass regeneration rate was observed within this interval, and the root length and dry mass of roots, rhizomes and stolons were higher compared to the highest concentration.

O objetivo deste artigo é descrever a expressão da financeirização em um conjunto de dez empresas e grupos econômicos atuantes no comércio de planos e seguros de saúde no Brasil entre 2008 e 2016, selecionadas pelo faturamento e pelo tamanho da carteira de clientes. As dimensões contábil/financeira e patrimonial foram analisadas a partir dos balanços patrimoniais e fluxos de caixa cotejados com indicadores microeconômicos de financeirização e dos registros de alteração na composição societária depositados em juntas comerciais. Para analisar o posicionamento político das empresas recorreu-se a dados primários de entrevistas semiestruturadas com representantes qualificados bem como à análise de relatórios aos acionistas e notícias de mídia especializada. Em síntese, a dominância financeira encontra expressão nas empresas de planos de saúde estudadas, mas a sua caracterização não obedece a um padrão homogêneo universalmente reproduzível, devendo a pesquisa empírica ocupar um lugar de destaque na investigação do fenômeno. Sendo a saúde e o seu componente assistencial definidos constitucionalmente como bens de relevância pública que solicitam o amparo de políticas estáveis e equitativas na distribuição dos recursos disponíveis e a tendência oligopolista e concentradora de recursos inerentes ao processo de financeirização contraditória com essa diretriz, e dado o lócus estratégico ocupado por essas empresas, as perspectivas projetadas para o conjunto do sistema tendem a evoluir para aumento dos gastos totais em saúde com maior concentração de recursos assistenciais e puncionamento dos recursos em circulação pela esfera da acumulação financeira.

The article aims to describe the characteristics of financialization in a set of ten companies and economic groups operating health plans and insurance in Brazil from 2008 to 2016, selected according to their turnover and the size of their client portfolio. The financial/accounting and net worth dimensions were analyzed according to the balance sheets and cash flows, compared to microeconomic indicators of financialization and the records of changes in the shareholding structure filed with commercial boards. The authors analyzed the companies’ policy positions based on primary data from semi-structured interviews with qualified representatives and the analysis of shareholder reports and news from the specialized media. In short, financial dominance is expressed in the health plans studied here, but their characterization does not follow a universally reproducible and homogeneous pattern, and empirical research should play a key role in further investigating the phenomenon. Since health and healthcare are defined constitutionally as publicly relevant goods that require support by stable and equitable policies in the distribution of available resources, and given the oligopolistic and concentrating trend in the inherent resources in the process of financialization (in opposition to this guideline) and the strategic place occupied by these companies, the prospects for the system as a whole tend to evolve towards an increase in total health expenditures, with greater concentration of healthcare resources and circulation of resources in the financial accumulation sphere.

Para analizar el posicionamiento político de las empresas se recurrió a datos primarios de entrevistas semiestructuradas con representantes cualificados, así como al análisis de informes a los Accionistas y noticias de medios especializados. En resumen, el dominio financiero encuentra expresión en las empresas de planes de salud estudiadas, pero su caracterización no obedece a un patrón homogéneo universalmente reproducible, debiendo ocupar la investigación empírica un lugar de relevancia en la investigación del fenómeno.

Abstract Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China’s Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients’ overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.

ABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful outcomes on the sustainability of agriculture and the environment. In addition, they lead to other deleterious effects, such as sedimentation and eutrophication of water bodies. Estimation of soil losses due to water erosion in sub-basins is essential for prediction of soil degradation, especially in areas of semi-intensive cultivation, such as coffee fields. Thus, the aim of this study was to estimate soil losses in relation to the limit of soil loss tolerance in Oxisols (Latossolos Vermelhos Distróficos) under coffee cultivation. This study was conducted from March 2015 to January 2017 in the Córrego da Laje Hydrographic Sub-basin in the municipality of Alfenas in the southern region of Minas Gerais, southeastern Brazil. Soil losses due to water erosion were estimated from the revised universal soil loss equation and compared to soil loss tolerance. Morphological, physical, and chemical properties of the soil were used, as well as geoprocessing techniques, remote-sensing images, and data from the literature. The results show potential soil losses from 0.01 to 18.77 Mg ha-1 yr-1, with an average of 1.52 Mg ha-1 yr-1. The soil loss tolerance ranged from 5.19 to 5.90 Mg ha-1 yr-1, with 7.35 % of the area having larger losses. Areas with steeper slopes and no sustainable practices have soil losses above the tolerance level and are thus a priority for adoption of measures to mitigate erosive effects. The revised universal soil loss equation enabled water erosion modeling and identification of areas with the highest rates of potential soil loss in watersheds.

RESUMO Embasamento: Pacientes com doença de Wilson (DW) apresentam comprometimento cognitivo, principalmente de funções executivas. Existem dúvidas sobre quais outros fatores poderiam estar associados ao declínio cognitivo global nesses pacientes. Objetivo: Avaliar quais fatores estão associados ao pior desempenho em teste cognitivo global em pacientes com DW. Métodos: Vinte pacientes com DW em tratamento regular foram submetidos à avaliação cognitiva com os seguintes testes: Mini-Exame do Estado Mental, escala de demência de Mattis (DRS), fluência verbal, bateria cognitiva breve, desenho do relógio, bacteria de avaliação frontal, Stroop, teste de seleção de cartões de Wisconsin, Hopper, Cubos e ao questionário de Pfeffer. As alterações em RM foram quantificadas. Pacientes com desempenho alterado na DRS foram comparados aos pacientes com desempenho normal. Resultados: Nove pacientes apresentavam desempenho alterado na DRS. Eles apresentavam menor nivel educacional (9,11±3,58 × 12,82±3,06 anos, respectivamente) e maior quantidade de alterações na RM (9,44±2,74 × 6,27±2,45). A presença de hipersinal no globo pálido na RM foi mais frequente nesse grupo (66,6% × 9,0%), com OR=5,38 (IC 95% 0,85-33,86). Conclusão: Alterações cognitivas globais foram frequentes nesta amostra de pacientes com DW e se associaram à baixa escolaridade, quantidade de alterações em RM e a hipersinal no globo pálido à RM.

ABSTRACT Background: Patients with Wilson's disease (WD) present cognitive impairment, especially in executive functions. Which other factors might be associated with global cognitive decline in these patients remains unclear. Objective: To assess which factors are associated with worse performance on a global cognitive test in patients with WD. Methods: Twenty patients with WD underwent cognitive assessment with the following tests: the Mini-Mental State Examination (MMSE), Dementia Rating Scale (DRS), verbal fluency test, brief cognitive battery, clock drawing test, Frontal Assessment Battery, Stroop test, Wisconsin card sorting test, Hopper test, cubes (WAIS) and the Pfeffer questionnaire. MRI changes were quantified. Patients with poor performance on the DRS were compared to patients with normal performance. Results: Nine patients had a poor performance on the DRS. This group had lower educational level (9.11±3.58 × 12.82±3.06) and a greater number of changes on MRI (9.44±2.74 × 6.27±2.45). The presence of hyperintensity in the globus pallidus on MRI was more frequent in this group (66.6% vs 9.0%), with OR=5.38 (95% CI 0.85-33.86). Conclusion: Global cognitive impairment was prevalent in this sample of patients with WD and was associated with low educational level, number of changes on MRI and MRI hyperintensity in the globus pallidus.

Resumo: A concentração e internacionalização de empresas de planos de saúde no Brasil conferiram-lhes feição financeira. Considerando a necessidade de compreender os padrões de acumulação desse setor, o trabalho examina estratégias de expansão das empresas de planos de saúde por meio da periodização de atributos da oferta e demanda e exame da trajetória patrimonial recente de um dos grandes grupos do setor. Entre os anos 1960 e 2000, ocorreram alterações na escala das demandas por planos de saúde e adesão das empresas a estratégias de acumulação de longo prazo. A partir do século XXI, as alterações nas estruturas societárias da maior empresa brasileira, compatíveis com o regime de acumulação financeirizada, resultaram na multiplicação de seu capital em um curto intervalo de tempo. O aprofundamento da segmentação do sistema de saúde, em um contexto marcado pela desaceleração da economia, questiona a preservação dos subsídios públicos para os planos privados.

Abstract: The concentration and internationalization of health plan companies in Brazil gave them a clearly financial face. Based on the need to understand the health care industry's capital accumulation patterns, the current study examines health plan companies' expansion strategies through the classification of their supply and demand characteristics by recent historical periods and an analysis of recent shareholding trends in one of the leading corporations in the Brazilian health care industry. The 1960s to 2000s witnessed changes in the scale of demands for health plans and adherence by companies to long-term accumulation strategies. Beginning in the early 21st century, changes in the shareholding structures of the largest Brazilian company, consistent with the financialization of its accumulation regime, resulted in the rapid multiplication of its capital. Deepening segmentation of the health care system in a context marked by the downturn in the national economy challenges the preservation of public subsidies for private health plans.

Resumen: La concentración e internacionalización de empresas de planes de salud en Brasil les han conferido un carácter financiero. Considerando la necesidad de comprender los padrones de acumulación de ese sector, el trabajo examina estrategias de expansión de las empresas de planes de salud, mediante la periodización de atributos de oferta y demanda y el examen de la trayectoria patrimonial reciente de uno de los grandes grupos del sector. Entre los años 1960 y 2000, se produjeron alteraciones en la escala de las demandas por parte de planes de salud y una adhesión de las empresas a estrategias de acumulación a largo plazo. A partir del siglo XXI, las alteraciones en las estructuras societarias de la mayor empresa brasileña, compatibles con el régimen de acumulación de carácter financiero, resultaron en la multiplicación de su capital en un corto intervalo de tiempo. La profundización de la segmentación del sistema de salud, en un contexto marcado por la desaceleración de la economía, cuestiona la preservación de los subsidios públicos para los planes privados.
