RESUMO O objetivo deste estudo foi avaliar o desempenho reprodutivo dos perdizes de asas vermelhas em cativeiro utilizando diferentes sistemas de acasalamento durante três épocas de reprodução. Os dados foram coletados de agosto a março, durante três épocas de reprodução da espécie. Dez casais e quatro grupos de perdizes de asas vermelhas foram selecionados aleatoriamente para a formação do sistema de acasalamento monogâmico e poliginoso, respectivamente, com coleta de ovos de ambos os sistemas. Os traços avaliados foram o número de ovos por fêmea, a quebra dos ovos e a fertilização dos ovos. Os dados foram analisados estatisticamente pelo método dos mínimos quadrados e pela regressão logística. Os animais na estratégia de acasalamento de casais foram superiores (P<0,05) em termos de número de óvulos por fêmea, em comparação com a estratégia de acasalamento do grupo. Foi observada uma alta taxa de quebra de ovos (P<0,05) nos grupos perdizes de asas vermelhas. Ovos de animais em estratégia de acasalamento de casais foram 5,24 e 11,5 mais propensos a serem fertilizados do que os de estratégia de grupo em duas épocas de reprodução. Em geral, a eficiência reprodutiva em termos de baixa quebra de ovos, alta produção de ovos e fertilidade foi observada para os tinâmicos de asas vermelhas do sistema de acasalamento monogâmico.

ABSTRACT The aim of this study was to evaluate the reproductive performance of red-winged tinamous in captivity using different mating systems during three breeding seasons. The data were collected from August to March during three breeding seasons of the species. Ten couples and four groups of red-winged tinamous were randomly selected for formation of the monogamous and polygynous mating system, respectively, with egg collection from both systems. The traits evaluated were number of eggs per female, egg breaking and egg fertilization. Data were statistically analyzed by the least square method and logistic regression. Animals in couples mating strategy were superior (P<0.05) in terms of number of eggs per female compared to the group mating strategy. High egg breaking rate (P<0.05) in the red-winged tinamous groups was observed. Eggs of animals in couples mating strategy were 5.24 and 11.5 more likely to be fertilized than those of group strategy in two breeding seasons. In general, the reproductive efficiency in terms of low egg breaking, high egg production and fertility was observed for red-winged tinamous from the monogamous mating system.

Resumo Teve-se por objetivo no presente trabalho verificar a magnitude e tendência da evapotranspiração de referência horária (EToh), bem como associar e analisar as séries diárias de ETo (ETod) e a soma da ETo horária (ETo24h) em 24 h, estimada pelo modelo Penman-Monteith ASCE para o Estado do Paraná (tipos climáticos Cfa e Cfb). Dados de umidade relativa (UR), temperatura (T), radiação solar (Rs) e velocidade do vento (u2) foram obtidos de 25 estações meteorológicas do Instituto Nacional de Meteorologia, entre 01/12/2016 e 08/11/2018. As análises foram realizadas por meio de regressão linear e associações considerando a raiz quadrada do erro quadrado médio, coeficiente de correlação e índice de concordância. A tendência da EToh teve distribuição gaussiana, com valores mais altos entre as 12:00 e 14:00 h, com média máxima de 0.44 mm h−1 (para o clima Cfa) e 0.5 mm h−1 (em clima Cfb). A diferença média entre os valores de ETo24h e ETod foi pequena (5.1% para Cfa e 7.4% para Cfb), resultando em estreitas associações lineares. Os resultados obtidos indicam que a EToh tem bom potencial para ser utilizada no planejamento e manejo na área de engenharia de água e solo, no Estado do Paraná.

Abstract The objective of this study was to verify the magnitude and trend of hourly reference evapotranspiration (EToh), as well as associate and analyze daily ETo (ETod) series and the sum of hourly ETo (ETo24h) in 24 h, estimated with the Penman-Monteith ASCE model for Paraná State (Cfa and Cfb climate type). Relative humidity (RH), temperature (T), solar radiation (Rs) and wind speed (u2) data were obtained from 25 meteorological stations from the National Meteorological Institute (INMET), between December 1, 2016 to November 8, 2018. The analyzes were performed by linear regression and associations considering the root mean square error, correlation coefficient and index of agreement. The EToh trend has a Gaussian distribution, with the highest values between 12:00 p.m. and 2:00 p.m., with the maximum average being 0.44 mm h−1 (Cfa climate type) and 0.35 mm h−1 (Cfb climate type). The average difference between the ETo24h and ETod values was small (5.1% for Cfa and 7.4% for Cfb), resulting in close linear associations. The results obtained indicate that EToh has good potential to be used in planning and management in the field of soil and water engineering, in Paraná State.

RESUMO: Surtos da mosca-dos-estábulos (Stomoxys calcitrans) têm sido associados a usinas sucroalcooleiras no Brasil. Este estudo objetivou avaliar a atratividade da aspersão de vinhaça, um subproduto líquido da produção de etanol aplicado após a colheita em áreas canavieiras, a adultos de S. calcitrans. A abundância desta mosca foi monitorada em uma usina de cana-de-açúcar por 21 dias, entre agosto e setembro de 2014, em Nova Alvorada do Sul/MS. Após a colheita mecanizada da cana e consequente deposição de grande quantidade de palha no campo, a área de estudo (13,5ha) foi cercada com 22 armadilhas adesivas cilíndricas (“alsynite”). Fertirrigação com vinhaça foi iniciada imediatamente após instalação das armadilhas. A coleta das moscas capturadas nas armadilhas foi realizada diariamente às 7:00 a.m., 11:00 a.m. e 15:00 p.m. Foram capturados 83.593 espécimes de S. calcitrans, sendo 5.516 (6,6%) atraídos nas primeiras cinco horas após a aplicação da vinhaça. Maior número de S. calcitrans foi capturado na primeira semana do estudo (53.937 moscas), com pico no 4º dia (12.818 moscas), influenciado pelas condições climáticas adversas ocorridas nos dias anteriores. O presente estudo confirma que o processo de fertirrigação de áreas canavieiras com aspersão de vinhaça após a colheita é atrativo à S. calcitrans, aumentando rapidamente sua abundância nos dias subsequentes à aplicação.

ABSTRACT: Stable fly (Stomoxys calcitrans) outbreaks have been associated with sugarcane mills in Brazil. This study aimed to evaluate the attractivity of vinasse, a liquid byproduct of ethanol production applied to postharvest sugarcane fields, to adult S. calcitrans. Stable fly abundance was monitored for 21 days in August-September 2014, at a sugarcane mill in the municipality of Nova Alvorada do Sul, state of Mato Grosso do Sul, Brazil. Following mechanized harvesting of sugarcane and the consequent deposition of large amounts of plant residue (straw) in the field, the study area (13.5ha) was surrounded by 22 sticky cylinder (“alsynite”) traps. The area was fertigated with vinasse immediately after the traps were placed. Insects caught in the traps were collected daily at 7:00 a.m., 11:00 a.m. and 15:00 p.m. A total of 83,593 specimens of S. calcitrans were caught, of which 5,516 (6.6%) were attracted within the first five hours after vinasse application. The highest number of S. calcitrans was caught in the first week following vinasse application, with a peak on the 4th day (12,818 flies), which was influenced by adverse weather conditions on the previous days. This study confirms that fertigation of sugarcane fields by spraying vinasse after the harvest attracts S. calcitrans, thus quickly increasing their abundance over the days following application.

ABSTRACT Caddisflies are a highly diverse group of aquatic insects, particularly in the Neotropical region where there is a high number of endemic taxa. Based on taxonomic contributions published until August 2019, a total of 796 caddisfly species have been recorded from Brazil. Taxonomic data about Brazilian caddisflies are currently open access at the “Catálogo Taxonômico da Fauna do Brasil” website (CTFB), an on-line database with taxonomic information on the animal species occurring in Brazil. The order Trichoptera at CTFB includes a catalog of species recorded for the country, with synonymic lists, distribution throughout six biomes, 12 hydrographic regions, and 27 political states (including Federal District) from Brazil. The database is constantly updated to include newly published data. In this study, we reviewed the taxonomic effort on Brazilian caddisflies based on data currently in CTFB database. The accumulation curve of species described or recorded from the country, by year, shows a strong upward trend in last 25 years, indicating that it is possible that there are many more species to be described. Based on presence/absence of caddisfly species at three geographic levels (biomes, hydrographic regions, and states), second order Jackknife estimated at least 1,586 species occurring in Brazil (with hydrographic regions as unities), indicating we currently know about 50% of the Brazilian caddisfly fauna. Species distribution by Brazilian biomes reveals that the Atlantic Forest is the most diverse, with 490 species (298 endemic), followed by the Amazon Forest, with 255 species (101 endemic). Even though these numbers may be biased because there has been more intense collecting in these two biomes, the percentage of endemic caddisfly species in the Atlantic Forest is remarkable. Considering the distribution throughout hydrographic regions, clustering analyses (UPGMA) based on incidence data reveals two groups: northwestern basins and southeastern. Although these groups have weak bootstrap support and low similarity in species composition, this division of Brazilian caddisfly fauna could be related to Amazon-Atlantic Forest disjunction, with the South American dry diagonal acting as a potential barrier throughout evolutionary time.

ABSTRACT. The objectives were to evaluate the biodiversity of bees, forage behavior and their effect on fruit production in the gherkin crop (Cucumis anguria L.) in the campus of the University Center Moura Lacerda in two years. The frequency and type of collection of the insects in the flowers was observed by counting from 8:00 a.m. to 5:00 p.m., in the first 10 minutes of each time, for three distinct days in each year. The percentage of fruiting was quantified in 25 female flowers covered with nylon compared to the 25 female flowers uncovered in the two years. The flowers were visited by the Africanized honey bees Apis mellifera and the native bees Plebeia sp., Exomalopsis sp. and Melissodes sp., and the Africanized honey bees presented higher frequency and constancy with a higher number of visits in the male flowers compared to the female ones and these visits occurred between 8:00 a.m. and 3:00 p.m. Without the visitation of the bees there was no fruit production, and both the Africanized honey bee and the native ones when collecting nectar and pollen, visited both female and male flowers, carrying pollen in their body, being considered important pollinators of this culture.

RESUMO A suplementação proteico-energética (SPE) é uma estratégia adequada à bovinocultura de corte no período seco do ano, embora sua adoção equivocada possa comprometer seu benefício/custo. O objetivo deste estudo foi avaliar o desempenho de novilhas Nelore em pastagem diferida de Urochloa decumbens sob dois períodos de SPE, e realizar análise econômica desses sistemas de produção. O experimento foi conduzido sob delineamento inteiramente ao acaso, com 147 e 55 dias de SPE (sistemas 1 e 2, respectivamente), de 21/06 a 15/11/2016, com 16 e 20 novilhas nos sistemas 1 e 2, respectivamente. Os dados de desempenho foram analisados utilizando-se o PROC MIXED do SAS®, e as médias comparadas por PDIFF (P<0,05). Os pesos médios foram semelhantes (P>0,05) entre os sistemas de produção nas pesagens de 21/06, 12/07, 02/08, 23/08 e 15/11/2016. Os valores presentes líquidos foram positivos sob a taxa anual de desconto de 4%, sendo viáveis financeiramente. Por apresentarem taxa interna de retorno superior à taxa mínima de atratividade, os sistemas foram atrativos para investimento. Foi obtido balanço econômico positivo de R$ 25,26/animal para substituição do sistema 1 pelo sistema 2. A redução de 92 dias na SPE proporciona desempenho semelhante entre novilhas e maior eficiência econômica do sistema de produção.

ABSTRACT Protein-energy supplementation (SPE) is an adequate strategy for beef cattle during drought season of the year, although the wrong adoption might compromise its cost/benefit ratio. The aim of this study was to evaluate Nellore heifers’ performance under SPE periods and to draw economic analysis of production systems. The experiment was conducted under a completely randomized design, with two systems: 147 and 55 days of SPE (Systems 1 and 2), from 06/21/2016 to 11/15/2016, with 16 and 20 heifers to Systems 1 and 2, respectively. Performance data were analyzed by SAS® PROC MIXED and means compared by PDIFF (P< 0.05). The weight means were similar between the production systems (P> 0.05) at weighing of 06/21, 07/12, 08/02, 08/23 and 11/15/2016. The net present values were positive under annual discount rate of 4%, being financially viable. By presenting internal return rate higher than the minimum attractiveness rate, the systems were attractive for investment. Positive economic balance was obtained of R$ 25.26/animal to replace System 1 by 2. The reduction of 92 days in SPE provides similar performance between Nellore heifers and greater economic efficiency of the production system.

RESUMO Diferentes horários de irrigação resultam em diferentes taxas de transpiração, devido à disponibilidade de água e sua interação com a demanda evapotranspirativa. O déficit de pressão de vapor é um indicador preciso da capacidade evaporativa da atmosfera e pode afetar as plantas, devido ao movimento da água no sistema contínuo solo-planta-atmosfera. Objetivou-se avaliar o crescimento, produtividade e eficiência do uso da água de pimentões submetidos a horários (08:00 h e 14:00 h) e níveis de reposição hídrica (60 %, 80 %, 100 %, 120 % e 140 % da necessidade hídrica da cultura - ETc) baseados na demanda evapotranspirativa. O aumento nos níveis de irrigação puderam ser ajustados ao modelo linear para as variáveis número de frutos por planta, peso médio e total de frutos por planta, comprimento dos frutos e peso seco da raiz, do caule e total. A irrigação às 14:00 h aumentou o peso total e médio e o número de frutos por planta, bem como o comprimento dos frutos, se comparada à irrigação às 08:00 h, além de aumentar a produtividade em 50,82 % (2.343,0 g planta-1 para 3.533,6 g planta-1) e a eficiência do uso da água em 55,64 %. Em áreas sujeitas à escassez de água, o estabelecimento de horários de irrigação baseados em práticas de manejo de irrigação pode aumentar a produtividade e a eficiência no uso de água em pimentões.

ABSTRACT Different irrigation times result in variable transpiration rates, due to the water availability and its interaction with the evapotranspiration demand. The vapor pressure deficit is an accurate indicator of the atmosfere evaporative capacity and can affect plants because of the movement of water in the soil-plant-atmosphere continuum system. This study aimed to evaluate the plant growth, yield and water-use efficiency of bell peppers under irrigation times (8 a.m. and 2 p.m.) and water replacement levels (60 %, 80 %, 100 %, 120 % and 140 % of the crop water requirement - ETc) based on the evapotranspiration demand. The increase in the irrigation levels could be fit to linear models for the variables number of fruits per plant, mean and total fruit weight per plant, fruit length, and root, stem and total dry weight. Irrigation at 2 p.m. increased the total and mean fruit weight and number of fruits per plant, as well as fruit length, if compared to the irrigation at 8 a.m., besides increasing the yield by 50.82 % (2,343.0 g plant-1 to 3,533.6 g plant-1) and the water-use efficiency by 55.64 %. In areas subjected to water shortages, establishing irrigation times based on irrigation management practices can increase the water-use efficiency and yield for bell peppers.

ABSTRACT The objective of this study was to analyze the effectiveness of forest fire hazard indices for the Serra do Brigadeiro State Park region (MG). Although no weather station is present in this territory, the use of data obtained in the municipality of Viçosa (38 km distance) was effective to calculate the hazard. According to the results, the use of high and very high hazard classes to predict occurrences proved to be more efficient. The Telicyn, Nesterov, FMA and FMA+ indices showed better results when daily mean data was used while FWI responded better with daily maximum temperature and relative humidity at 3:00 p.m. The P-EVAP and FWI indices were the most efficient to predict fires in the study region.

RESUMO: Este estudo objetivou avaliar aspectos comportamentais de ovinos Santa Inês criados em pasto em clima tropical úmido. Para tanto, foram utilizados nove carneiros Santa Inês, mantidos a pasto, expostos diretamente ao clima, sem sombra, durante 24 dias, sendo 12 dias alternados em cada período (seco e chuvoso) em 2015. Os parâmetros comportamentais avaliados foram consumo de alimento, ócio em pé, ócio deitado e ruminação. As observações ocorreram das 08:00h às 17h:55min. O delineamento experimental foi o inteiramente casualizado (DIC) com dois tratamentos (período chuvoso e período seco), nove repetições, um animal por unidade experimental. Para entender as correlações dos parâmetros comportamentais com as variáveis climáticas foi realizada a correlação de Pearson. Foram observados valores médios gerais aproximados entre os períodos chuvoso e seco para as variáveis comportamentais, porém, houve maior ingestão no volume de água no período seco (9,59L/ovino). Também, ocorreu diferença no comportamento dos animais ao longo do dia. No horário mais quente do dia, das 14h às 15h, registrou-se ócio em pé de 25,83min. e ócio deitado de 1,21min., e os animais passaram menor tempo consumindo alimento (27,08min.) em relação aos demais horários. Podemos concluir que os ovinos apresentaram parâmetros comportamentais semelhantes nos períodos chuvoso e seco, porém, quando observamos os horários dos dias, os comportamentos são diferentes. A principal atividade registrada foi o pastejo. As variáveis temperatura e a umidade relativa do ar influenciam de forma diferente o comportamento dos ovinos entre as estações do ano, sendo mais marcantes no período seco.

ABSTRACT: This study aimed to evaluate behavioral aspects of Santa Inês sheep in pasture in humid tropical climate. In order to do so, nine Santa Inês sheep were kept on pasture, exposed to the climate directly, without shade, for 24 days, with 12 alternate days in each period (dry and raining) in 2015. The behavioral parameters evaluated were: food consumption, standing idleness, lying idle and rumination. Observations occurred from 08:00 A.M. to 05:55 P.M. The experimental was a completely randomized design (CRD) with two treatments (rainy season and dry period), nine replications, one animal per experimental unit. To understand the correlations of the behavioral parameters with the climatic variables, Pearson’s correlation was performed. Approximate average values between the rainy and dry periods for the behavioral variables were observed, but there was a greater intake in the volume of water in the dry period (9.59L/sheep). Also, there were significant differences in the behavior of the animals throughout the day. In the hottest time of the day, at 02:00 P.M., there was standing idle of 25.83min., lying idle of 1.21min., and spent less time-consuming food (27.08min.) in relation to other schedules. We concluded that the sheep had similar behavioral parameters in the rainy and dry periods, but when we observe the times of the days, the behaviors are different. The main activity recorded was grazing, and the variables, temperature and relative humidity of the air influence differently between the seasons, being more marked in the dry period.

ABSTRACT Soil temperature is a physical property of great agricultural importance in the soil-plant relationship and in energy exchange with the atmosphere. This study was conducted in a degraded Cambissolo Háplico Ta Eutrófíco (Cambisol; Inceptisol) in the Irecê Identity Territory, Bahia, Brazil, aiming to evaluate the hourly, daily, and monthly fluctuations of soil temperature at depth, and soil thermal diffusivity in the castor bean crop. Hourly soil temperature data from February 4, 2014, to September 30, 2015, were obtained by using thermocouple sensors (copper-constantan) horizontally installed at 0.05, 0.10, and 0.20 m depths. Soil thermal diffusivity was estimated by phase and amplitude methods. Results showed that, for most days, the soil temperature was at the level recommended for castor bean. The maximum and minimum hourly and daily soil temperatures were observed in October and July, respectively, and the maximum soil temperature values occurred at 4 p.m. (0.05 m), 5 p.m. (0.10 m), and 7 p.m. (0.20 m). Soil temperature variability is low, requiring few measurement points to estimate this factor in an area. The amplitude method led to soil thermal diffusivity values compatible with results in the literature. The absence of a relationship between thermal diffusivity and soil moisture was attributed to the clay-loam soil texture, predominance of micropores, and iron oxides allowing greater approximation to the soil particles, with high thermal diffusivity even under low soil moisture conditions.

RESUMO Muitas fazendas, situadas em bacias leiteiras, estão migrando da atividade leiteira para a pecuária de corte e tal migração vem sendo feita de forma muitas vezes não criteriosa ou sem assistência técnica. Neste estudo, objetivou-se avaliar a viabilidade econômico-financeira e o risco econômico de diferentes sistemas de cria de gado de corte, explorados em regiões de bacia leiteira. O trabalho consistiu em um estudo de múltiplos casos que tiveram como critério de escolha três sistemas que desenvolvessem atividade de cria. O horizonte de informações econômicas dos sistemas foi de 36 meses e os sistemas de criação foram caracterizados por meio de levantamento de dados realizados em visitas periódicas, utilizando-se questionários previamente elaborados. Foram estimados o valor presente líquido e a taxa interna de retorno do investimento, e realizaram-se as análises de sensibilidade e o risco de cada sistema de criação. Os três sistemas de cria foram viáveis financeiramente por terem VPL positivo a uma taxa de desconto de 6,0% a.a. O retorno da atividade mostrou-se mais sensível aos investimentos realizados na compra de terra e nas matrizes. Os riscos desses sistemas, apesar da possibilidade de mudanças no mercado, foram considerados baixos, tornando-os opções de investimentos atrativas, quando comparados aos rendimentos obtidos com a caderneta de poupança.

ABSTRACT Many farms located in milk-producing regions in Brazil have turned from dairy to beef production systems. These business migrations have been done with no particular care or any use of technical assistance. In this study, we aimed to evaluate the economics aspects, such as viability and risk assessment of different cow-calf systems established in those regions. The work consisted of a multiple case study using three farms. The economic horizon lasted 36 months, with data collection obtained in periodic visits, using a pre-designed survey. Net present value (NPV) and internal rate of return (IRR) on investment were estimated. Further analysis of sensitivity was made for these indicators. All cow-calf systems were economically viable with positive NPV, with a discount rate of 6.0% per year. The economic viability of the cow-calf systems was more sensitive to investments in land and animals - sires and cows). The assessment of risks in these cow-calf systems showed them to be low, despite the possibility of changes in the market. The cow-calf systems, when submitted to technical assistance, may be an attractive option of investment compared to investing in saving account.

RESUMO Entre os diferentes materiais utilizados para a reparação e o aumento da bexiga, a submucosa intestinal suína (SIS) é o mais amplamente investigado e se destaca por sua habilidade como um arcabouço celular. Nesse contexto, o exame ultrassonográfico possibilita a avaliação pós-operatória, bem como a detecção precoce de potenciais complicações. O objetivo deste artigo é descrever os principais achados ultrassonográficos em cães submetidos à cistoplastia utilizando a SIS acelular e semeada com células musculares lisas homólogas aos 30 (M30) e 60 (M60) dias de pós-operatório. As alterações ultrassonográficas pós-operatórias incluíram irregularidades e espessamento da parede da bexiga, especialmente aos M30. Além disso, foram visualizados sedimento urinário e urólitos em animais submetidos à cistoplastia utilizando a SIS acelular. A ecografia abdominal foi útil na avaliação pós-operatória dos animais submetidos à cistoplastia utilizando a SIS acelular e semeada com células musculares lisas homólogas.

ABSTRACT Among the different materials for bladder augmentation, porcine intestinal submucosa (SIS) is the most widely investigated and stands out for its ability as a cell scaffold. In this context, the ultrasound examination allows the detection of changes from the surgical procedure, enabling the early verification of potential complications and evaluation of patient outcomes. The aim of this paper is to describe the main sonographic findings in dogs submitted to cystoplasty using acellular SIS and seeded with homologous smooth muscle cells at 30 (M30) and 60 (M60) days postoperatively. Sonographic changes included irregularities and thickening of bladder wall especially at M30. Additionally, were visualized urinary sediment and uroliths in animals submitted to acellular SIS cistoplasty. Abdominal ultrasonography was useful in the postoperative evaluation of animals undergoing cystoplasty with acellular or seeded SIS.

ABSTRACT. This article aimed to describe the profile of pre-hospital care provided to pregnant women and puerperal mothers by the Mobile Emergency Care Service (SAMU) in a municipality in Bahia, Brazil, in 2010. This is a descriptive, documentary, research with a quantitative approach, conducted by means of secondary data generated from 385 health care records; data collection took place through a form adapted from the health care records of this service, from December 2011 to April 2012. Data were tabulated by frequency distribution and analyzed by simple statistics. Out of the total number of health care records analyzed, 360 pregnant women (93.5%) were provided with care, and 78 became pregnant more than once (20.3%); 107 were at the age group from 20 to 24 years (27.8%); 95 were at a gestational age between 38 and 42 weeks (24.7%); and 208 were provided with care during labor (54.0%). Among the pregnant women, 337 underwent delivery at a hospital (87.5%) and 152 were referred to public maternity hospitals (39.5%); 99 patients were provided with care between 12:00 p.m. and 06:00 a.m. (25.7%). As for umbilical cord clamping, 13 procedures were registered (3.5%), as well as 11 deliverance cases (2.9%). It was concluded that the profile of pre-hospital care provided to pregnant women and puerperal mothers by the service focused on labor, delivery, and puerperium, something which may be related to the perception of ease, quickness, and safety.

O objetivo deste trabalho foi estudar a produção e o valor nutritivo de nove espécies de leguminosas forrageiras herbáceas tropicais, cultivadas sob dois níveis de irradiação luminosa e seis frequências de corte na estação chuvosa, em Anhembi (SP), Brasil. Parcelas puras foram estabelecidas ao sol e sob plantação de Eucalyptus grandis, com 8 anos de idade, com 1.000 árvores/ha, que interceptou mais de 80% da radiação luminosa incidente. Avaliou-se a taxa de acúmulo de matéria seca, a proteína bruta e a digestibilidade in vitro da matéria seca em amostras de plantas colhidas em intervalos de 30, 60, 90 e 180 dias, com cortes adicionais aos 120 e 150 dias. Sob pleno sol, as leguminosas testadas toleraram cortes mais frequentes (intervalos de 30 - 90 dias), exceto o Lablab. Na sombra, o grau de tolerância variou conforme a espécie; em termos de produção de MS e de persistência, a Centrosema e a Puerária se destacaram dentre as demais leguminosas comparadas, quando os cortes foram realizados em intervalos de 60 dias, enquanto o Arachis e o Estilosantes foram os mais produtivos quando os cortes ocorreram em intervalos de 120 dias, mantendo o valor nutricional. O Alysicarpus e a Aeschynomene não persistiram sob o nível de sombreamento que prevaleceu nesse experimento.

The aim of this study was to evaluate the production and nutritive value of nine tropical legumes under two light intensities and six cutting regimens in the wet season, in Anhembi (SP) - Brazil. Pure stands were established in full light and under an eight-year-old eucalyptus plantation with 1.000 plants per hectare. The trees intercepted over80% of the incident radiation. Dry matter herbage accumulation, dry matter in vitro digestibility and crude protein under the cutting intervals 30, 60, 90 and 180 days, with additional cuttings at 120 and 150 days were evaluated. With the exception of Lablab, all other tested legume species tolerated higher cutting frequency under when grown under full sun light then under shade. The degree of shade-tolerance varied according to the species; Centrosema and Pueraria produced well at cutting intervals of 60 days, showing higher dry matter production and persistence while Arachis and Stylosanthes showed better results under longer cutting intervals, keeping the nutritional value, and can be indicated for differential grazing. Alysicarpus and Aeschynomene did not persist under the prevailing conditions.

Liver fibrosis occurring as an outcome of non-alcoholic steatohepatitis (NASH) can precede the development of cirrhosis. We investigated the effects of sorafenib in preventing liver fibrosis in a rodent model of NASH. Adult Sprague-Dawley rats were fed a choline-deficient high-fat diet and exposed to diethylnitrosamine for 6 weeks. The NASH group (n=10) received vehicle and the sorafenib group (n=10) received 2.5 mg·kg-1·day-1 by gavage. A control group (n=4) received only standard diet and vehicle. Following treatment, animals were sacrificed and liver tissue was collected for histologic examination, mRNA isolation, and analysis of mitochondrial function. Genes related to fibrosis (MMP9, TIMP1, TIMP2), oxidative stress (HSP60, HSP90, GST), and mitochondrial biogenesis (PGC1α) were evaluated by real-time quantitative polymerase chain reaction (RT-qPCR). Liver mitochondrial oxidation activity was measured by a polarographic method, and cytokines by enzyme-linked immunosorbent assay (ELISA). Sorafenib treatment restored mitochondrial function and reduced collagen deposition by nearly 63% compared to the NASH group. Sorafenib upregulated PGC1α and MMP9 and reduced TIMP1 and TIMP2 mRNA and IL-6 and IL-10 protein expression. There were no differences in HSP60, HSP90 and GST expression. Sorafenib modulated PGC1α expression, improved mitochondrial respiration and prevented collagen deposition. It may, therefore, be useful in the treatment of liver fibrosis in NASH.
