ABSTRACT This work aimed to evaluate the agronomic efficiency of cowpea cultivars inoculated with rhizobia strains recommended for cowpea in a semiarid environment. Experiments were carried out in Mossoró, Rio Grande do Norte, in two agricultural cycles: the first from January to April 2019, and the second from June to August of the same year. The experimental design adopted was randomized blocks with four replications arranged in a 4 × 4 x 2 factorial scheme, with treatments consisting of four cowpea cultivars: ‘BRS Imponente’, ‘BRS Itaim’, ‘BRS Novaera’, and ‘BRS Tumucumaque’ as well as three sources of N, two strains of Bradyrhizobium spp. registered for cowpea (BR 3262 and BR 3267) and, the application of mineral N (50 kg ha-1), beyond an absolute control, without inoculation or application of mineral N. In addition to two planting seasons. The cultivar ‘BRS Tumucumaque’ showed greater productive potential. The inoculation of cowpea seeds with Bradyrhizobium strains BR 3262 and BR 3267 provided grain yields similar to those obtained with the application of mineral N.

RESUMO Este trabalho teve como objetivo avaliar a eficiência agronômica de cultivares de feijão-caupi inoculadas com linhagens de rizóbios recomendadas para feijão-caupi em ambiente semiárido. Os experimentos foram conduzidos em Mossoró, Rio Grande do Norte, em duas safras agrícolas: o primeiro de janeiro a abril de 2019, e o segundo de junho a agosto do mesmo ano. O delineamento experimental adotado foi de blocos ao acaso com quatro repetições em esquema fatorial 4 × 4 x 2, com tratamentos constituídos por quatro cultivares de feijão-caupi: 'BRS Imponente', 'BRS Itaim', 'BRS Novaera' e 'BRS Tumucumaque' e três fontes de N, duas linhagens de Bradyrhizobium spp. registradas para o feijão-caupi (BR 3262 e BR 3267), aplicação de N mineral (50 kg ha-1), além de uma testemunha absoluta, sem inoculação ou aplicação de N mineral. Além de duas épocas de plantio. A cultivar 'BRS Tumucumaque' apresentou maior potencial produtivo. A inoculação de sementes de feijão-caupi com as linhagens de Bradyrhizobium BR 3262 e BR 3267 proporcionou rendimentos de grãos semelhantes aos obtidos com a aplicação de N mineral.

Resumo Os mamíferos são organismos carismáticos que desempenham um papel fundamental na função ecológica e nos serviços ecossistêmicos, como polinização, dispersão de sementes, ciclagem de nutrientes e controle de pragas. O Estado de São Paulo representa apenas 3% do território brasileiro, mas detém 33% da diversidade de mamíferos. A maior parte de seu território é dominado pela agricultura, pastagens e áreas urbanas que afetam diretamente a diversidade e a persistência dos mamíferos na paisagem. Além disso, São Paulo possui o maior porto da América Latina e o maior reservatório de petróleo costeiro do Brasil, com 600 km de extensão de litoral com diversas espécies de mamíferos marinhos. Essas infraestruturas afetam a diversidade, distribuição, ecologia e o futuro dos mamíferos no estado. Aqui, respondemos cinco perguntas principais: 1) Qual é a diversidade de mamíferos silvestres no Estado de São Paulo? 2) Onde eles ocorrem? 3) Qual é o seu impacto positivo e negativo no bem-estar humano? 4) Como os mamíferos persistem em paisagens modificadas pelo homem? 5) Qual é o futuro dos mamíferos no estado? O estado de São Paulo possui 255 espécies de mamíferos nativos, com quatro espécies endêmicas, duas delas globalmente ameaçadas de extinção. Pelo menos seis espécies (dois marsupiais, ariranha, veado-campeiro, veado-cambuta e tatu-canastra) foram extirpadas do estado devido à caça e perda de habitat. O intenso uso humano da terra no estado forçou muitas espécies de mamíferos a mudar sua dieta para lidar com a intensa fragmentação e agricultura. A monocultura em larga escala facilitou a invasão de espécies exóticas, como porcos selvagens (javaporco) e a lebre europeia. Várias espécies de áreas abertas estão expandindo suas áreas de distribuição (lobo-guará, veado-catingueiro) sobre áreas desmatadas e provavelmente refletem mudanças em direção a um clima mais seco. Como o estado possui o maior sistema rodoviário do Brasil, cerca de 40 mil mamíferos de 33 espécies são mortos por ano em colisões, causando um prejuízo econômico de 12 milhões de dólares/ano. A diversidade de mamíferos está concentrada nos maiores remanescentes florestais da Serra do Mar e no interior do Estado, principalmente nas regiões de Ribeirão Preto e Jundiaí. As lacunas amostrais estão concentradas em todo o interior do estado, principalmente na região noroeste. Os mamíferos silvestres desempenham um papel fundamental em muitos serviços ecossistêmicos, mas também podem ser uma preocupação em trazer novas doenças emergentes para as populações humanas. Embora a taxonomia de mamíferos pareça ser bem conhecida, mostramos que novas espécies estão sendo continuamente descobertas no estado. Portanto, pesquisas usando tecnologias tradicionais e novas (eDNA, iDNA, drones), monitoramento populacional de longo prazo, a investigação da interface do conflito homem-vida selvagem e a compreensão do papel único no ecossistema desempenhado pelos mamíferos são um caminho futuro para promover uma paisagem verde sustentável aliada ao bem-estar humano no estado. O plantio de corredores florestais ou de cerrado, principalmente junto aos principais sistemas fluviais, no planalto, o controle da caça ilegal nas áreas costeiras, o manejo dos regimes de fogo no Cerrado e a mitigação dos atropelamentos devem ser uma prioridade para proteger essa notável diversidade de mamíferos.

Abstract Mammals are charismatic organisms that play a fundamental role in ecological functions and ecosystem services, such as pollination, seed dispersal, nutrient cycling, and pest control. The state of São Paulo represents only 3% of the Brazilian territory but holds 33% of its mammalian diversity. Most of its territory is dominated by agriculture, pastures, and urban areas which directly affect the diversity and persistence of mammals in the landscape. In addition, São Paulo has the largest port in Latin America and the largest offshore oil reservoir in Brazil, with a 600 km stretch of coastline with several marine mammal species. These human-made infrastructures affect the diversity, distribution, ecology, and the future of mammals in the state. Here, we answer five main questions: 1) What is the diversity of wild mammals in São Paulo state? 2) Where are they? 3) What is their positive and negative impact on human well-being? 4) How do mammals thrive in human-modified landscapes? 5) What is the future of mammals in the state? The state of São Paulo holds 255 species of native mammals, with four endemic species, two of them globally endangered. At least six species (two marsupials, Giant otter, Pampas deer, Brazilian dwarf brocket deer, and Giant armadillo) were extirpated from the state due to hunting and habitat loss. The intense human land use in the state forced many mammalian species to change their diet to cope with the intense fragmentation and agriculture. Large-scale monoculture has facilitated the invasion of exotic species such as wild boars (javali) and the European hare. Several “savanna-dwelling” species are expanding their ranges (Maned wolf, Brocket deer) over deforested areas and probably reflect changes towards a drier climate. Because the state has the largest road system, about 40,000 mammals from 33 species are killed per year in collisions causing an economic loss of 12 million dollars/year. The diversity of mammals is concentrated in the largest forest remnants of Serra do Mar and in the interior of the State, mainly in the regions of Ribeirão Preto and Jundiaí. Sampling gaps are concentrated throughout the interior of the state, particularly in the northwest region. Wild mammals play a fundamental role in many ecosystem services, but they can also be a concern in bringing new emergent diseases to humans. Although the taxonomy of mammals seems to be well known, we show that new species are continuously being discovered in the state. Therefore, continuous surveys using traditional and new technologies (eDNA, iDNA, drones), long-term population monitoring, investigation of the interface of human-wildlife conflict, and understanding of the unique ecosystem role played by mammals are future avenues for promoting sustainable green landscapes allied to human well-being in the state. The planting of forest or savanna corridors, particularly along with major river systems, in the plateau, controlling illegal hunting in the coastal areas, managing fire regimes in the Cerrado, and mitigating roadkill must be prioritized to protect this outstanding mammal diversity.

Abstract Sunflower is one of the most important oilseeds in the world, whose achenes are valued in several industrial chains, mainly for the extraction and processing of its oil. Although there is some information in the literature, the nitrogen (N) requirements for sunflower in semiarid conditions under irrigation are not yet clear. The experimental design used randomized blocks, with treatments in subdivided plots with four replications during two agricultural seasons. The N doses (e.g., 0, 30, 60, 90 and 120 kg ha−1) were assigned to the plots, and to the four sunflower cultivars used (e.g., Aguará 06, Altis 99, Multissol and BRS 122), which were planted in the subplots. The N doses for the maximum achene yields for the Multissol and BRS 122 cultivars were 81.8 and 86.6 kg ha−1, respectively, while N doses of 120 kg ha−1 produced the maximum achene yields for the Altis 99 and Aguará 06 cultivars in the 2016 crop season. In 2017, the Multissol and BRS 122 cultivars were given N doses of 100.7 and 92.8 kg ha−1, respectively, and the Altis 99 and Aguará 06 cultivars were each given an N dose of 120 kg ha−1 of N. The fertirrigated doses of maximum economic efficiency of N were 60 and 70 kg ha−1 for the Multissol and BRS 122 cultivars, respectively. For the oil yields, the maximum N doses of 78.0 and 86.7 kg ha−1 for the BRS 122 and Aguará 06 cultivars and for the Multissol and Altis 99 cultivars at an N dose of 120 kg ha−1 were used for the 2016 harvest. In 2017, the BRS 122 and Multissol cultivars received N doses of 88.6 and 99.1 kg ha−1, respectively, and the Altis 99 and Aguará 06 cultivars received N doses of 120 kg ha−1. The use of fertigation allowed greater efficiency for the N doses in the sunflower cultivars in the semiarid region.

Resumen El girasol es una de las oleaginosas más importantes del mundo, cuyos aquenios son valorados en varias cadenas industriales, principalmente para la extracción y procesamiento de su aceite. Aunque existe alguna información en la literatura, los requerimientos de nitrógeno (N) para el girasol en condiciones semiáridas bajo riego aún no están claros. El diseño experimental utilizó bloques al azar, con tratamientos en parcelas subdivididas con cuatro repeticiones durante dos temporadas agrícolas. Las dosis de N (por ejemplo, 0, 30, 60, 90 y 120 kg ha-1) se asignaron a las parcelas, y a los cuatro cultivares de girasol utilizados (por ejemplo, Aguará 06, Altis 99, Multissol y BRS 122), que se plantaron en las subparcelas. Las dosis de N para los máximos rendimientos de aquenio para los cultivares Multissol y BRS 122 fueron de 81,8 y 86,6 kg ha-1, respectivamente, mientras que las dosis de N de 120 kg ha-1 produjeron los máximos rendimientos de aquenio para los cultivares Altis 99 y Aguará 06 en la temporada de cultivo 2016. En 2017, los cultivares Multissol y BRS 122 recibieron dosis de N de 100,7 y 92,8 kg ha-1, respectivamente, y los cultivares Altis 99 y Aguará 06 recibieron una dosis de N de 120 kg ha-1 cada uno. Las dosis de fertirrigación de máxima eficiencia económica de N fueron de 60 y 70 kg ha-1 para los cultivares Multissol y BRS 122, respectivamente. Para los rendimientos de aceite, en la cosecha de 2016 se utilizaron las dosis máximas de N de 78,0 y 86,7 kg ha-1 para los cultivares BRS 122 y Aguará 06 y para los cultivares Multissol y Altis 99 con una dosis de N de 120 kg ha-1. En 2017, los cultivares BRS 122 y Multissol recibieron dosis de N de 88,6 y 99,1 kg ha-1, respectivamente, y los cultivares Altis 99 y Aguará 06 recibieron dosis de N de 120 kg ha-1. El uso de la fertirrigación permitió una mayor eficiencia de las dosis de N en los cultivares de girasol de la región semiárida.

RESUMO A determinação da dose econômica de nitrogênio para o algodoeiro colorido pode aumentar a produtividade e a renda dos agricultores. O experimento foi realizado em condição de campo na Fazenda Experimental da Universidade Federal Rural do Semi-Árido, nos anos de 2016 e 2017. O objetivo foi determinar a dose econômica de nitrogênio para quatro cultivares de algodão colorido. O delineamento experimental foi em blocos casualizados, com parcelas subdivididas e quatro repetições. Nas parcelas principais casualizaram-se cinco doses de nitrogênio (0, 50, 100, 150 e 200 kg ha-1) e nas subparcelas, quatro cultivares de algodão colorido (BRS Safira, BRS Rubi, BRS Topázio e BRS Verde). As características avaliadas foram produtividade de algodão em caroço, produtividade de fibra de algodão, teor de nitrogênio no tecido foliar, dose técnica e dose econômica de nitrogênio. Maior produtividade de algodão naturalmente colorido pode ser obtida utilizando as doses econômicas de 140 kg ha-1 N para as cultivares BRS Rubi e BRS Verde, 150 kg ha-1 N para BRS Topázio e 160 kg ha-1 N para a BRS Safira. Maior produtividade foi alcançada com a cultivar BRS Topázio e menor, com a cultivar BRS Verde.

ABSTRACT Determining the economical dose of nitrogen (N) for colored cotton can increase yield and income of farmers. The experiment was carried out under field conditions at the Experimental Farm of the Universidade Federal Rural do Semi-Árido, in the years 2016 and 2017. The objective was to determine the economical N dose for four colored cotton cultivars. The experimental design was in randomized blocks, with split plots and four repetitions. Five N doses (0, 50, 100, 150 and 200 kg ha-1) were randomized in the main plots and four colored cotton cultivars (BRS Safira, BRS Rubi, BRS Topázio and BRS Verde) were randomized in the subplots. The characteristics evaluated were seed cotton yield, cotton fiber yield, N concentration in leaf tissue, technical dose and economical dose of N. Higher yield of naturally colored cotton can be obtained using the economical doses of 140 kg ha-1 N for cultivars BRS Rubi and BRS Verde, 150 kg ha-1 N for BRS Topázio and 160 kg ha-1 N for BRS Safira. Highest yield was achieved with the cultivar BRS Topázio and lowest with the cultivar BRS Verde.

RESUMEN Objetivos: este estudio investigó la bioactividad del extracto de hoja en bruto (EHB) y las fracciones hexano (HX) y acetato de etilo (AcOEt) de Talinum paniculatum solo y en asociación con fluconazol (FLC) contra cepas de referencia y aislados clínicos de Candida albicans resistente a FLC. Además, evaluó la capacidad antioxidante, la composición química de esta planta y los mecanismos subyacentes del efecto fungicida. Métodos: la actividad antifúngica se evaluó mediante microdilución en caldo para establecer las concentraciones inhibitorias mínimas (CIM) y microbicidas mínimas (CMM). Durante el tratamiento con FLC y productos vegetales se detectó la generación de especies reactivas de oxígeno (ERO) (radicales hidroxilo [HO●]) en células de C. albicans utilizando las sondas fluorescentes permeables a la membrana APF y HPF. El perfil de cromatografía líquida de alta resolución (CLAR), el análisis cuantitativo de compuestos antioxidantes y el ensayo DPPH fueron evaluados. Resultados: el EHB y las fracciones presentaron una excelente actividad antifúngica y selectividad contra las células de C. albicans, pero no tuvieron efectos sinérgicos con FLC. Los valores de CIM para EHB y sus fracciones contra la cepa referencia de C. albicans fueron del orden de: HX (31,25 μg ml-1) < AcOEt (62,5 μg ml-1) < EHB (500 μg ml-1), y contra C. albicans resistente a FLC: HX (125 μg ml-1)= AcOEt < EHB (500 µg ml-1). EHB y sus fracciones fueron más potentes antifúngicos que FLC contra los aislados clínicos. Además, estos productos vegetales tienen efectos fungicidas contra C. albicans resistentes a FLC, esto conirmó el potencial antifúngico. Por el contrario, durante la asociación se demostró que los productos vegetales causan un aumento en la CIM de FLC de 2 a 16 veces. La exposición a FLC aumentó los niveles de ERO (HO●) en las células de C. albicans. Los aumentos en las CIM de FLC se debieron a la acción de los antioxidantes presentes en EHB y sus fracciones para prevenir la inhibición del crecimiento mediada por ERO inducida por FLC en C. albicans. Conclusión: T. paniculatum puede ser una fuente de compuestos bioactivos con potencial antifúngico. Sin embargo, debido al uso común de su hoja comestible, se recomienda usarla con precaución durante la terapia con FLC (ya que puede disminuir la susceptibilidad a FLC).

SUMMARY Aims: This study investigated the bioactivity of the crude leaf extract (CLE) and fractions hexane (HX) and ethyl acetate (EtOAc) from Talinum paniculatum alone and in association with fluconazole (FLC) against reference strain and clinical isolates of FLC-resistant Candida albicans. Furthermore, the antioxidant capability, chemical composition of this plant, and the effect's underlying mechanisms were evaluated. Methods: The antifungal activity was evaluated using checkerboard assay to establish the minimum inhibitory (MIC) and minimum microbicidal concen trations (MMC). During FLC and plant products challenges, the reactive oxygen species (ROS) generation (hydroxyl radicals [HO●]) were detected in C. albicans cells using the membrane-permeable fluorescent probes APF and HPF. High-performance liquid chromatography (HPLC) profile, quantitative analysis of antioxidant compounds, and free radical scavenging activity (DPPH assay) tests were performed. Results: The CLE and fractions presented outstanding antifungal activity and selectivity against C. albicans cells but had no synergistic effect’s with FLC. The MIC values for CLE and its fractions against C. albicans reference strain were in the order of HX (31.25 µg ml-1) < EtOAc (62.5 μg ml-1) < CLE (500 μg ml-1), and against FLC-resistant C. albicans HX (125 μg ml-1) = EtOAc < CLE (500 μg ml-1). CLE and its fractions had more potent antifungal activities than FLC against the clinical isolates. Moreover, fungicidal effect’s for these plant products were demonstrated against FLC-resistant C. albicans, which further conirmed an antifungal potential. Conversely, during association, plant products were shown to cause an increase in FLC MIC anywhere from 2- to 16-fold. FLC exposure led to an increase in the steady-state levels of ROS (HO●) in C. albicans cells. Next, we found that the increases in FLC MICs were owing to action of antioxidants containing-CLE and its fractions in preventing FLC-induced ROS-mediated growth inhibition of C. albicans. Conclusion: T. paniculatum can be a source of bioactive compounds with antifungal potential. However, because of the common use of its edible leaf, caution is advised during therapy with FLC (since it can decrease FLC susceptibility).

RESUMEN Propósito: evaluamos el potencial antibacteriano del extracto de hoja en bruto (EHB) y las fracciones hexano (HX) y acetato de etilo (AcOEt) de Talinum paniculatum solo y en asociación con oxacilina (OXA) contra Staphylococcus aureus resistente a OXA (ORSA, ambientales) y S. aureus sensible a OXA (OSSA, ATCC 25923). Además, se realizaron pruebas de toxicidad. Métodos: la actividad antibacteriana se evaluó mediante microdilución en caldo para establecer las concentraciones inhibitorias mínimas (CIM) y bactericidas mínimas (CBM). Se evaluó la toxicidad en ratones. Resultados: los valores de CIM para el EHB y sus fracciones contra ORSA y OSSA fueron del orden de HX (500 μg ml-1) = AcOEt < EHB (4000 μg ml-1). AcOEt y HX presentaron actividades antibacterianas sobresalientes contra ORSA, y estas fracciones fueron bactericidas hacia OSSA. Por el contrario, las asociaciones entre el producto vegetal (EHB, AcOEt o HX) y OXA no mostraron efectos sinérgicos. Durante estas asociaciones, hubo un aumento en las CIM de OXA de 2 a 4092 veces. EHB no mostró toxicidad a una dosis de 5 g kg-1. Conclusión: aunque T. paniculatum es una buena fuente de compuestos bioactivos con potencial antiestofilocócico, los investigadores deben ser cautelosos, ya que su hoja comestible puede interferir con la terapia con OXA (mitigando la inhibición del crecimiento inducida por OXA o la muerte de S. aureus y promoviendo resistencia bacteriana).

SUMMARY Propose: We evaluated the antibacterial potential of the crude leaf extract (CLE) and fractions hexane (HX) and ethyl acetate (EtOAc) from Talinum paniculatum alone and in association with oxacillin (OXA) against OXA-resistant Staphylococcus aureus (ORSA, environment isolates) and OXA-sensitive S. aureus (OSSA, ATCC 25923). Furthermore, toxicity tests were performed. Methods: The antibacterial activity was evaluated through checkerboard assay (broth microdilution) to establish the minimum inhibitory (MIC) and minimum bactericidal concentrations (MBC). Toxicity test in mice was assessed. Results: The MIC values for the CLE and its fractions against ORSA and OSSA were in the order of HX (500 μg ml-1) = EtOAc < CLE (4000 μg ml-1). EtOAc and HX presented outstanding antibacterial activities against ORSA, and these fractions were bactericidal toward OSSA. Conversely, the associations between plant product (CLE, EtOAc, or HX) and OXA exhibited no synergistic effects. During these associations, there was an increase in OXA MICs anywhere from 2- to 4092-fold. The CLE presented absence of toxicity at a dose of 5 g kg-1 (in vivo). Conclusion: Although T. paniculatum be a good source of bioactive compounds with antistaphylococcal potential, the researchers should be cautious, since its edible leaf may interfere with OXA therapy (mitigating OXA-induced growth inhibition or killing of S. aureus and enhancing S. aureus resistance).

RESUMO Objetivou-se avaliar a emergência, o crescimento, o acúmulo de biomassa e a tolerância de genótipos de amendoim sob estresse salino. O experimento foi desenvolvido em ambiente protegido (casa de vegetação), avaliando seis genótipos de amendoim (Tatuí, L7151, Caiapó, IAC8112, IAC881 e Havana) submetidos a dois níveis de salinidade da água de irrigação (0,5 (controle) e 3,5 dS m-1), arranjados em esquema fatorial 6 x 2, em delineamento experimental de blocos casualizado, com cinco repetições, com duas plantas por parcela. As plantas foram cultivadas durante 30 dias após a semeadura, em lisímetros com capacidade para 0,5 dm3, preenchidos com uma mistura de solo não salino e não sódico, com substrato comercial na proporção de 1:1 base em volume. Durante esse período as plantas foram avaliadas quanto à emergência, crescimento, acúmulo de biomassa e tolerância à salinidade e dissimilaridade. Os genótipos Tatuí e L7151 são os mais sensíveis ao estresse salino na fase de emergência. A irrigação com água de alta salinidade reduziu o crescimento, o acúmulo de biomassa dos genótipos de amendoim, sendo os genótipos Caiapó e IAC8112 os menos afetados. A classificação de tolerância à salinidade teve a seguinte sequência: Caiapó > IAC8112 > Havana > Tatuí > IAC881 > L7151.

ABSTRACT This study aimed to evaluate the emergence, growth, biomass accumulation and tolerance of peanut genotypes under salt stress. The experiment was conducted in a protected environment (greenhouse), evaluating six peanut genotypes (Tatuí, L7151, Caiapó, IAC8112, IAC881 and Havana), which were subjected to two levels of irrigation water salinity (0.5 [control] and 3.5 dS m-1), arranged in a 6 x 2 factorial scheme, in a randomized block design, with five repetitions, with two plants per plot. Plants were cultivated for 30 days after sowing in lysimeters with capacity for 0.5 dm3, filled with a mixture of non-saline, non-sodic soil and commercial substrate in 1:1 proportion on volume basis. During this period, plants were evaluated for emergence, growth, biomass accumulation, tolerance to salinity and dissimilarity. The genotypes Tatuí and L7151 are the most sensitive to salt stress in the emergence stage. Irrigation with high-salinity water reduced the growth and biomass accumulation of the peanut genotypes, and Caiapó and IAC8112 were the least affected. The classification of salinity tolerance had the following sequence: Caiapó > IAC8112 > Havana > Tatuí > IAC881 > L7151.

RESUMO A irrigação é um fator limitante para o desenvolvimento das culturas, e todas as fontes de água contem sais, podendo acumular-se no solo e na planta, comprometendo seu desenvolvimento. Dentre algumas alternativas para atenuar os efeitos negativos dos sais nos vegetais está a utilização de vermicomposto, sendo este um adubo orgânico condicionador do solo e fonte de nutrientes para as plantas. Dessa forma, o estudo teve como objetivo avaliar o crescimento e o índice de clorofila do noni à salinidade da água de irrigação em substrato sem e com proporções de vermicomposto. Foi utilizado o delineamento inteiramente casualizado, com quatro repetições utilizando o esquema fatorial 4 × 3, correspondente a quatro níveis de condutividade elétrica da água de irrigação (0,5; 1,5; 3,0; 4,5 dS m-1), em substratos sem húmus e com 33,33 e 66,66% de húmus com o solo. Três meses após a germinação foram avaliados: altura de planta; diâmetro caulinar; número de folhas; índices de clorofila (a, b e total) das folhas; e matéria fresca e seca da parte aérea e radicular das plantas. O aumento da salinidade na água de irrigação influência negativamente no crescimento em altura, diâmetro caulinar, produção de biomassa e índices de clorofila a e total, mas com menor intensidade nos substratos com húmus, que melhora a fertilidade do substrato e favorece o crescimento das plantas de noni, independentemente da salinidade da água de irrigação; no entanto, seu efeito benéfico diminui com o aumento da condutividade elétrica da água de irrigação.

ABSTRACT Irrigation is a limiting factor for the development of crops, and all water sources contain salts, which can accumulate in the soil and in the plant, compromising its development. The use of vermicompost is one of the alternatives to mitigate the negative effects of salts on plants. This organic compost is a soil conditioner and a nutrient source for plants. Thus, this study aimed to evaluate the growth and chorophyll of noni (Morinda citrifolia L.) in response to the salinity of irrigation water in substrates with and without vermicompost. A completely randomized design in a 4 × 3 factorial scheme was used, corresponding to four levels of electrical conductivity of the irrigation water (0.5, 1.5, 3.0 and 4.5 dS m-1), in three soil substrates (without humus, with 33.33 and 66.66% of humus). Three months after germination, the following variables were evaluated: plant height; stem diameter; number of leaves; chlorophyll index (a, b and total) in the leaves; and fresh and dry matter of shoots and roots. The increase of salinity in irrigation water negatively influences growth in height, stem diameter, biomass production and chlorophyll a and total indexes, but with lower intensity in substrates with humus, that improves the fertility of the substrate and favors the growth of noni plants, regardless of the salinity of the irrigation water; however, its beneficial effect decreases with the intensification of electrical conductivity of irrigation water.

Abstract Objective: To evaluate the sequential changes of hemodynamic and metabolic parameters in patients who underwent aorta no-touch off-pump coronary artery bypass surgery (OPCAB). Methods: Prospective study involving twenty-seven consecutive patients who underwent aorta no-touch OPCAB. The FloTrac/PreSep/Vigileo™ system (Edwards Lifesciences) was used to continuously record heart rate (HR), mean arterial blood pressure (MABP), central venous pressure (CVP), continuous cardiac index (FCI), stroke volume (SV), stroke volume variation (SVV), and central venous oxygen saturation (ScvO2). The parameters were assessed 5 min before, during and 5 min after each anastomosis (left anterior descending [LAD], posterior descending [PD], obtuse marginal [OM] and diagonal [Dg]). Postoperative lactate was also evaluated. Results: There was no significant change in HR and MABP for all anastomoses, except for MABP during PD grafting (-10.1±2.7 mmHg, P=0.03). There was a significant decrease in ScvO2 only during PD and OM anastomoses (-9.4±0.4, P=0.03; -4.4±0.4, P=0.02; respectively). CVP drop after PD manipulation was strongly associated with a higher lactate during the first hours after surgery (r=-0.82; P=0.001). These hemodynamic changes were transient and entirely recovered after the heart was returned to its anatomical position. No significant differences were observed in FCI, SVV, or the systemic vascular resistance index (SVRI) during all anastomoses, except for a drop in SVRI during PD grafting (-8.03±2.3, P=0.007). SV tended to decrease during the procedure in all territories, but with statistically significant drop only in PD and OM grafting (-10.4±1.2, P=0.02; -13.6±5.1, P=0.007; respectively). Conclusion: Heart displacement for performing aorta no-touch OPCAB is well tolerated, with transient and endurable hemodynamic variations.

Resumen El objetivo del estudio, conducido en Uberlândia, Minas Gerais, Brasil, fue identificar estrategias de defoliación con el fin de mejorar la estructura de una pastura de Urochloa brizantha (sin. Brachiaria brizantha) cv. Marandu. Se compararon 3 estrategias: (1) mantener el pasto a una altura de 15 cm en otoño e invierno (W) y de 30 cm en primavera (Sp) y verano (Su) (15W-30Sp-30Su); (2) mantener el pasto a una altura de 30 cm durante todo el período experimental (30W-30Sp-30Su); y (3) mantener el pasto a una altura de 45 cm en otoño e invierno y de 30 cm en primavera y verano (45W-30Sp-30Su). El diseño experimental fue completamente al azar, con 4 repeticiones. Las parcelas se cortaron con tijeras a la altura respectiva semanalmente en invierno y 2 veces por semana en primavera, verano y otoño. Cada 28 días se midieron la densidad de brotes, el peso medio de los brotes, el índice de área foliar, la masa de forraje, el porcentaje de hojas vivas y el porcentaje de tallos. La masa forrajera en invierno se relacionó directamente con la altura del pasto (P<0.05), pero las diferencias desaparecieron en verano (P>0.05). La densidad media de los brotes fue independiente de la altura de corte, pero fue mayor en primavera y verano que en invierno (P<0.05). El peso medio de los brotes en invierno estuvo directamente relacionado con la altura de corte (P <0.05), pero las diferencias desaparecieron en verano. El porcentaje de hojas vivas en la pastura se vio afectado por la estación del año, con primavera>verano>invierno y por la altura de corte en otoño/invierno cuando el porcentaje de hojas estuvo inversamente relacionado con la altura de corte. El porcentaje de tallos en invierno estuvo directamente relacionado con la altura de corte. Estudios de pastoreo parecen justificados para determinar si estos resultados, obtenidos a nivel de parcela de corte, se reflejan bajo condiciones de pastoreo, y cuáles son los impactos en la producción animal.

Abstract The objective of this study was to identify defoliation strategies that might improve the structure of Urochloa brizantha (syn. Brachiaria brizantha) cv. Marandu (marandu palisadegrass). The following 3 defoliation strategies were compared in a plot study: sward kept at 15 cm in fall and winter (W) and 30 cm in spring (Sp) and summer (Su) (15W-30Sp-30Su); sward kept at 30 cm during the entire experimental period (30W-30Sp-30Su); and sward kept at 45 cm in fall and winter and 30 cm in spring and summer (45W-30Sp-30Su). The experimental design was completely randomized, with 4 replicates. Plots were cut with shears to the appropriate height weekly in winter and twice weekly in spring, summer and fall. Tiller density, mean tiller weight, leaf area index, forage mass, percentage of live leaf blades and percentage of stems were measured every 28 days. Forage mass in winter was directly related to pasture height (P<0.05) but differences had disappeared by summer (P>0.05). Mean tiller density was independent of cutting height but was higher in spring and summer than in winter (P<0.05). Mean tiller weight in winter was directly related to cutting height (P<0.05) but differences had disappeared by summer. The percentage of live leaf blades in the swards was affected by season with spring>summer>winter and by cutting height in fall/winter with leaf percentage inversely related to cutting height. Stem percentage in the swards in winter was directly related to cutting height. Grazing studies seem warranted to determine if these plot results are reflected under grazing conditions and what the impacts are on animal performance.

RESUMO Racional: A volumetria por tomografia computadorizada (VTC) é uma ferramenta útil para a previsão do peso do enxerto (PE) para o transplante hepático com doador vivo (TFDV). Poucos estudos examinaram a correlação entre o VTC e PE no parênquima hepático normal. Objetivo: Analisar a correlação entre VTC e PE em uma população adulta de doadores para o TFDV e realização de revisão sistemática dos modelos matemáticos existentes para calcular o peso de enxertos hepáticos parciais. Métodos: Foram revisados retrospectivamente 28 doadores consecutivos submetidos à hepatectomia direita para o TFDV entre janeiro de 2009 a janeiro de 2013. Todos os doadores eram adultos saudáveis com VTC pré-operatório. Os enxertos foram perfundidos com solução de preservação HTK. O volume estimado foi obtido por VTC e estes valores foram comparados com o peso real do enxerto, o qual foi aferido depois da hepatectomia e perfusão do enxerto. Resultados: A mediana do PE real foi de 782,5 g, média de 791,43±136 g, variando de 520-1185 g. A mediana do volume estimado do enxerto foi de 927,5 ml, média de 944,86±200,74 ml e variou de 600-1477 ml. A regressão linear volume estimado do enxerto e PE real foi significativamente linear (PE=0.82 do volume estimado do enxerto, r2=0,98, declive=0,47, desvio-padrão de 0,024 e p<0,0001). Correlação linear de Spearman foi de 0,65, com IC de 95% do 0,45-0,99 (p<0,0001). Conclusão: A regra de "um-para-um" não deve ser empregada em pacientes com parênquima hepático normal. A melhor estimativa do peso do enxerto hepático de doador vivo pode ser alcançado através da multiplicação do VTC por 0,82.

ABSTRACT Background: Computed tomography volumetry (CTV) is a useful tool for predicting graft weights (GW) for living donor liver transplantation (LDLT). Few studies have examined the correlation between CTV and GW in normal liver parenchyma. Aim: To analyze the correlation between CTV and GW in an adult LDLT population and provide a systematic review of the existing mathematical models to calculate partial liver graft weight. Methods: Between January 2009 and January 2013, 28 consecutive donors undergoing right hepatectomy for LDLT were retrospectively reviewed. All grafts were perfused with HTK solution. Estimated graft volume was estimated by CTV and these values were compared to the actual graft weight, which was measured after liver harvesting and perfusion. Results: Median actual GW was 782.5 g, averaged 791.43±136 g and ranged from 520-1185 g. Median estimated graft volume was 927.5 ml, averaged 944.86±200.74 ml and ranged from 600-1477 ml. Linear regression of estimated graft volume and actual GW was significantly linear (GW=0.82 estimated graft volume, r2=0.98, slope=0.47, standard deviation of 0.024 and p<0.0001). Spearman Linear correlation was 0.65 with 95% CI of 0.45 - 0.99 (p<0.0001). Conclusion: The one-to-one rule did not applied in patients with normal liver parenchyma. A better estimation of graft weight could be reached by multiplying estimated graft volume by 0.82.

RESUMO: Objetivou-se neste trabalho avaliar o efeito do cruzamento sobre as características biométricas escroto-testiculares de carneiros da raça Santa Inês e mestiços (Santa Inês x Dorper), submetidos à insulação escrotal, acompanhando o retorno dessas características aos valores previamente observados. Para isso, foram realizadas duas mensurações referentes à circunferência escrotal (CE), comprimento (C) e largura testicular (L), antes da insulação. O volume testicular (V) foi calculado pela fórmula V=2 [(r2) x π x h]. As bolsas de insulação foram fixadas ao redor do funículo espermático e escroto com fita adesiva e esparadrapo, permanecendo por sete dias. Após o período de insulação, as mensurações foram realizadas a cada sete dias, totalizando 15 mensurações durante todo o experimento. Os dados obtidos foram submetidos à análise de variância (ANOVA) para um delineamento em blocos casualizados, com dois blocos, 15 tratamentos e quatro repetições. As variáveis analisadas foram submetidas ao teste de Dunnett a 5% de probabilidade, para comparar os valores obtidos antes e após a insulação. Para a comparação entre as raças, as variáveis foram submetidas ao teste de Tukey a 5% de probabilidade. Todos os animais estudados sofreram influência significativa (P<0,05) após a insulação escrotal, porém os carneiros da raça Santa Inês retornaram aos valores anteriormente observados em um espaço de tempo mais curto do que os mestiços. Conclui-se que carneiros da raça Santa Inês apresentam maior resistência do que animais mestiços quando submetidos ao estresse térmico induzido pela insulação escrotal.

ABSTRACT: The objective of this study was to evaluate the effect of the racial crossing on scrotum-testicular biometric characteristics of four sheep Santa Ines and four crossbred (Santa Ines x Dorper) submitted to scrotal insulation, following the return of these characteristics to values previously reported. For this, two measurements were made regarding the scrotal circumference (SC), length (L) and testicular width (W) before treatments. The testicular volume (V) was calculated by the formula V=2 [(r2) x π x H]. The pouches were made with double-layer plastic, internally lined with cotton, and fixed around the spermatic funiculus and scrotum with adhesive tape and bandage remaining in this position for seven days. Measurements were made every seven days, totaling 15 measurements throughout the experiment. The data were submitted to analysis of variance (ANOVA) to a randomized block design with two blocks, 15 treatments and four replications. The variables analyzed were subjected to Dunnett test at 5% probability, to compare the values obtained before and after insulation. For comparison between the breeds, the variables were submitted to Tukey test at 5% probability. All animals studied suffered significant influence (P<0.05) after scrotal insulation, but Santa Ines returned to the values previously observed in a shorter period than the crossbred. In summary, sheep Santa Ines have a higher resistance than crossbred animals when subjected to thermal stress induced by scrotal insulation.

Abstract AIM The aim of this longitudinal study was to analyze the relationship between sleep disorder and intima-media thickness. METHOD Baseline measurements included carotid intima-media thickness, assessed by an ultrasound device; questionnaires about sleep and other behavioral variables; physical activity was measured by pedometer; body fatness was estimated by Dual-Energy X-ray Absorptiometry; fasting glucose, lipid profile and C-reactive protein were collected. RESULTS The occurrence rate of sleep-related disorders was 47% (95%CI= 37.2%-56.7%). Carotid intima-media thickness was related to symptoms of insomnia (r= 0.328 [0.141 to 0.493]) and, after adjustments for potential confounders, the relationship between carotid intima-media thickness and insomnia remained statistically significant (β= 0.121 [95%CI= 0.017; 0.225]). CONCLUSIONS In young adults, sleep disorder was significantly related to premature increase in carotid intima-media thickness.

RESUMO Objetivo Descrever o perfil de dor de sujeitos com lesão traumática do plexo braquial. Métodos Nós incluímos 65 indivíduos com lesão traumática do plexo braquial. O Douleur Neuropathique 4 foi usado para classificar a dor e o SF-36 foi usado para avaliar a qualidade de vida. Resultados Sujeitos com lesão traumática do plexo braquial eram em sua maioria homens jovens, vítimas de acidentes motociclísticos. A dor esteve presete em 75.4% dos indivíduos e 79% deles apresentaram dor neuropática, mais frequentemente localizada nas mãos (30.41%). O uso de dispositivos auxiliares (p = 0.05) e o estado civil foram, ambos, preditores independentes de dor. A dor ainda impactou negativamente da qualidade de vida (p = 0.001). Conclusões A dor é frequente em sujeitos com lesão traumática do plexo braquial. Apesar de envolver uma lesão do sistema nervoso a dor nociceptiva não é infrequente. A avaliação da dor, incluindo instrumentos validados, é essencial para direcionar as condutas clínicas de sujeitos com esta condição.

ABSTRACT Objective To describe the pain profile of patients with traumatic brachial plexus injury. Methods We enrolled 65 patients with traumatic brachial plexus injury. The Douleur Neuropathique 4 questionnaire was used to classify pain and the SF-36 was used to evaluate quality of life. Results The patients with traumatic brachial plexus injury were predominantly young male victims of motorcycle accidents. Pain was present in 75.4% of the individuals and 79% presented with neuropathic pain, mostly located in the hands (30.41%). The use of auxiliary devices (p = 0.05) and marital status (p = 0.03) were both independent predictors of pain. Pain also impacted negatively on the quality of life (p = 0.001). Conclusions Pain is frequent in patients with traumatic brachial plexus injury. Despite the peripheral nervous system injury, nociceptive pain is not unusual. Pain evaluation, including validated instruments, is essential to guide optimal clinical management of patients with the condition.
