Reuse made by the separation of whey can reduce the waste of human milk. However, the authors are not aware of the literature on treatments in human whey, made available by pasteurization holder, freeze-drying, spray drying, and high hydrostatic pressure. In this context, the present study applied treatments to human whey and evaluated their lipid and immunological quality. Among the results, a different formation in the triacylglycerol profile was evidenced after the application of spray drying and high hydrostatic pressure, while pasteurization and freeze-drying presented ion intensity close to the control human whey. In addition, pasteurization proved to be adequate for lipid nutritional quality and transformation factor-β1 (TGF-β1) concentration, while an increase in interleukin-10 (IL-10) levels was promoted, between 73 and 80%, after freeze-drying, spray drying, and high hydrostatic pressure. Through the principal component analysis, it is noteworthy that the processes presented divergences in terms of the effects caused, with similarity only between pasteurization and freeze-drying in the composition of fatty acids. However, it was observed that all processes were able to maintain the nutrients. Nevertheless, it is relevant to consider individual characteristics presented and the interest in the desired quality, which can be promising as a complementary product to infant feeding.

RESUMO O uso da irrigação desempenha papel fundamental no avanço das fronteiras agrícolas e no aumento da produtividade nas áreas de cultivo, principalmente em ambientes semiáridos que apresentam alta variação espaço-temporal de chuvas. Essa prática é sugerida até mesmo para cultivos adaptados como palma forrageira (Opuntia sp.) e sorgo (Sorghum bicolor). Assim, objetivou-se avaliar a rentabilidade do uso da irrigação no sistema solteiro e sistema consorciado palma-sorgo no semiárido. O delineamento experimental foi em blocos casualizados em esquema fatorial 5 × 3: cinco lâminas de irrigação por gotejamento (0, 25, 50, 75 e 100% da evapotranspiração de referência - ET0) e três sistemas de cultivo (palma forrageira solteira, sorgo solteiro e consórcio palma-sorgo), com quatro repetições. O tratamento 0% ET0 correspondeu à condição de sequeiro com uma lâmina de 355 mm. Foi conduzido um ciclo de palma e dois de sorgo (planta e rebrota) compreendidos de novembro 2014 a novembro de 2015. Verificou-se que os maiores custos para implantação dos sistemas de cultivo em condições irrigadas se devem à aquisição do sistema de irrigação e insumos, representando 85,3% do custo operacional efetivo. O sistema sorgo solteiro e o sistema palma forrageira-sorgo proporcionaram as maiores produtividades de matéria fresca (62.013,05 e 60.075,36 kg ha-1), respectivamente. Com base em indicadores econômicos, a adoção de lâminas de irrigação (25, 50, 75 e 100% ET0) promoveu lucros para os sistemas (solteiro e consorciado) a partir do segundo ano de implantação.

ABSTRACT Irrigation plays a fundamental role in advancing agricultural frontiers and increasing crop productivity, especially in semi-arid environments, because they exhibit high spatiotemporal rainfall variation. This practice is suggested even for adapted crops, such as forage cactus (Opuntia sp.), sorghum (Sorghum bicolor), and single or intercropping systems. In this study, aimed to evaluate the profitability of using irrigation in a single and intercropping forage cactus-sorghum system in a semi-arid region. The experimental design was in randomized blocks in a 5 × 3 factorial arrangement: five drip irrigation depths (0, 25, 50, 75, and 100% of the reference evapotranspiration - ET0) and three cropping systems (single forage cactus, single sorghum, and intercropping forage cactus-sorghum), with four replicates. The 0% ET0 treatment corresponded to rainfed conditions at a depth of 355 mm. A cycle of forage cactus and two sorghum cultivars (plant and regrowth) was conducted between November 2014 and November 2015. It was verified that the highest costs for implantation of the crop systems in irrigated conditions are due to the acquisition of irrigation and input systems, representing 85.3% of the effective operational cost. The single sorghum and forage cactus-sorghum systems provided the highest fresh matter productivity (62,013.05 and 60,075.36 kg ha-1, respectively). Based on economic indicators, the adoption of irrigation depths (25, 50, 75, and 100% ET0) promoted profits for the systems (single and intercropping) from the second year of implementation.

Abstract Samanea tubulosa Benth. it has been widely used in traditional medicine to treat inflammatory processes. The present study aimed to investigate the antinociceptive effect and mechanism of action of the fractions obtained from the Samanea tubulosa pods in mice. The antinociceptive activity was evaluated in formalin, capsaicin and glutamate tests and the. The possible mechanisms of action involved in the antinociceptive effect of the hexane and ethyl acetate fraction in the opioid system, also the the K + ATP channels and the L-arigine pathways of nitric oxide were evaluated. The chemical characterization analysis revealed in the hexane fraction the presence of triterpenes such as lupenone and lupeol. In the glutamate test, the hexane and ethyl acetate fractions showed antinociceptive activity at the dose of 12.5 and 25 mg kg-1. The antinociception produced by the hexane and ethyl acetate fractions was significantly reversed by naloxone, indicating that the fractions act through the opioid pathway. Antinociceptive response of the ethyl acetate fraction was blocked by glibenclamide, indicating that this fraction acts via the K + ATP channels activation. It is concluded that the fractions under study exert antinociceptive activity possibly related to the opioid route and through K+ ATP channels activation.

Resumen: En | Texto: En | PDF: En

ABSTRACT Reserva Ecológica de Guapiaçu (REGUA) is a private, protected area inside a remnant of the Atlantic Forest with high biodiversity. Although the bats of the reserve have been sampled for more than two decades, few studies have been published about them. Based on a compilation of data from several surveys, we present an updated list of the bat species there and compare it with surveys from other locations in the Atlantic Forest. From August 1998 to September 2021, at least 194 sampling nights were carried out at REGUA by different research groups from various institutions, totaling 448,092 m2.h of sampling. A total of 4,069 individuals were captured, belonging to 47 species and six families. Additionally, our results indicate that it is possible that some species that occur at REGUA have not been recorded yet. REGUA has the greatest number of bat species known for the Atlantic Forest. This most likely results from the fact that the reserve includes large areas of mature, continuous forest connected with other protected areas in the State of Rio de Janeiro. Another factor contributing to the high diversity of bat species at REGUA is that the area has been intensely sampled for many years. Given that the bat assemblage there appears to be a good proxy to ascertain the ecological patterns of biodiversity in well-preserved forests, we consider REGUA to be an important area for long-term ecological research. The basic knowledge about the ecological interactions of bats with different food resources and zoonotic microorganisms offers a unique opportunity to carry out research in several areas of knowledge, making it possible to address questions about bat assemblage structure, bat-parasite ecology, competition, niche partitioning, and other related studies.

The introduction of potentially toxic elements (PTEs) from industrial activities in water bodies, highlights the vulnerability of the environment and the need for actions focused on the implementation of mechanisms that help in the control and remediation of these impacts. The objective of the study was based on the integration of instrumental analytical methods, multivariate statistics, and computer simulation models, with the proposal of implementing realistic scenarios of the red mud plume behavior in the Pará River. The selected location was the municipality of Barcarena-PA, where is located an important alumina/aluminum industrial center. With the aid of the inductively coupled plasma optical emission spectrometer (ICP OES), the chemical elements Al, B, Cr, Fe, Mn, P, Ti, and Zn were quantified and the principal component analysis (PCA) allowed to select Al, B, Fe, P, and Zn as the most relevant with 98.68% of the accumulated variance. Some scenarios were proposed by the simulated hydrodynamic model, which evidenced that the Trambioca community would be the most affected in the first 13 h after the effluent overflowed, and the other locations in domino effect. The main scientific gain of the proposal is the possibility of the predictive scenarios to help the actions of containment and mitigation of environmental damages by public control agencies, institutions involved, and other competent bodies.

The present work intends to obtain and characterize a milk by-product: the human whey (HW), in order to avoid the excessive disposal of human milk (HM). The characterization was performed through analyzes of the chemical composition and fatty acids (FAs) and the triacylglycerol (TAG) lipid profile. The results indicated that the chemical composition altered significantly after the HW obtained, except for the percentage of ash and carbohydrates. About the FA composition, it was observed that strictly essential FA, essential FA and other FAs found in HM remained present in HW. For the nutritional lipids quality, the atherogenicity and the thrombogenicity indices presented desirable values, and the TAGs lipid profile revealed a variation in the analyzed samples. Therefore, it can be concluded that the characterized HW has potential for application in isolated form or to be used as an ingredient in other foods.

Abstract: Diosmin is a flavone glycoside clinically used as the main component of Daflon for the treatment of venous diseases. Several studies demonstrated that this natural compound can induce apoptosis in different tumors. However, isolated diosmin has not been studied regarding its effects on glioblastoma so far. Since glioblastoma is a highly lethal and fast-growing brain tumor, new therapeutic strategies are urgently needed. Herein, we evaluated the role of this flavonoid against glioblastoma cells using in vitro assays. Diosmin significantly reduced the viability of GBM95, GBM02, and U87MG glioblastoma cells, but not of healthy human astrocytes, as verified by MTT assay. Vimentin immunostaining showed that diosmin induced morphological changes in GBM95 and GBM02 cells, making them smaller and more polygonal. Diosmin did not inhibit GBM95 and GBM02 cell proliferation, but it caused DNA fragmentation, as verified by the TUNEL assay, and increased cleaved caspase-3 expression in these cells. In summary, diosmin is able to induce caspase-dependent apoptosis specifically in tumor cells and, therefore, could be considered a promising therapeutic compound against glioblastoma.

RESUMO A murcha de esclerotínia é uma das doenças mais importantes e difíceis de controlar da cultura da alface no Brasil e em muitos países. Este estudo foi realizado para selecionar isolados de Trichoderma antagônicos a Sclerotinia minor e S. sclerotiorum visando a desenvolver o controle biológico para este patossitema no Brasil. Trinta e um isolados de Trichoderma foram obtidos pela técnica de isca e testados em condições de laboratório com relação à sua habilidade de controlar S. minor e S. sclerotiorum, em plântulas de alface da cultivar Tainá, dispostas em placas de Petri contendo ágar-água. Subsequentemente quatro isolados eficientes para o controle e com elevada esporulação em condições de laboratório foram avaliados em casa-de-vegetação, em dois experimentos com ambos os patógenos em plântulas de alface da mesma cultivar. Vinte e dois isolados demonstraram capacidade de controlar S.minor e S. sclerotiorum nos experimentos conduzidos in vitro. Em condições de casa-de-vegetação os isolados testados, identificados como T. asperellum (IBLF 897, IBLF 904 e IBLF 914) e T. asperelloides (IBLF 908), reduziram o tombamento das mudas de alface causado por ambos os patógenos, mas foram mais efetivos para S. minor. O controle biológico da murcha de esclerotínia é uma tecnologia promissora para o manejo da doença, especialmente porque S. minor é a espécie predominante nos campos de produção de alface infestados do Brasil.

ABSTRACT Lettuce drop is one of the most important and difficult-to-control diseases affecting lettuce in Brazil and worldwide. This study was carried out to select Trichoderma isolates antagonistic to Sclerotinia minor and S. sclerotiorum, aiming to develop biological control for this pathosystem in Brazil. Thirty-one Trichoderma isolates were obtained with the use of baits and were tested under laboratory conditions for their ability to control S. minor and S. sclerotiorum in seedlings of lettuce cultivar Tainá cultured in Petri dishes containing water-agar medium. Subsequently, four isolates effective for control and showing high sporulation under laboratory conditions were evaluated in greenhouse in two experiments carried out with both pathogens in lettuce seedlings of the same cultivar. Twenty-two isolates showed ability to control S. minor and S. sclerotiorum in the in vitro experiments. The isolates tested under greenhouse conditions, identified as T. asperellum (IBLF 897, IBLF 904 and IBLF 914) and T. asperelloides (IBLF 908), reduced lettuce drop of seedlings caused by both pathogens but were more effective against S. minor. Biological control is a promising technology for the management of lettuce drop, especially because S. minor is the predominant species in infested lettuce fields in Brazil.

Resumo: Objetivou-se analisar a população de bastonetes Gram negativos aeróbios e anaeróbios facultativas no suco ruminal bovinos zebuínos de diferentes categorias, alimentados em pastagem tropical, e de novilhos alimentados com alto teor de grão e sem volumosos. Foram coletados fluido ruminal de 32 vacas, 50 novilhos e 50 bezerros alimentadas em pastagem de Brachiaria spp. e de 20 novilhos com acidose ruminal. Após diluições decimais, amostras foram inoculadas em placas contendo ágar MacConkey a 39°C. Para a identificação dos gêneros mais frequentes foram utilizadas provas bioquímicas. A concentração dessas bactérias não diferiu no ambiente ruminal de vacas, novilhos e bezerros de corte alimentados com pastagem tropical lignificada. Os gêneros mais frequentemente identificados para esses animais foram Escherichia, Enterobacter e Klebsiella. Novilhos alimentados sem volumoso e com acidose apresentaram maior taxa de detecção e maior população dessas bactérias no ambiente ruminal (>6 log/ml) quando comparados aos novilhos alimentados somente em pastagem. A espécie Escherichia coli foi predominante entre as bactérias isoladas do fluido ruminal de novilhos alimentados com dieta com alta concentração de grãos e com acidose (p<0,01). Constatou-se que em bovinos de corte, criados em pastagem tropical lignificada, a população desses microrganismos é baixa no ambiente ruminal e com maior diversidade de gêneros bacterianos. Entretanto em novilhos confinados e alimentos sem volumoso, apresentando acidose ruminal subaguda, ocorre desequilíbrio populacional com aumento da população de E. coli.

Abstract: This study aimed to analyze the population of Gram negative bacteria, rod-shaped aerobic and facultative anaerobes, in ruminal fluid of health Zebu cattle of different categories fed in tropical pasture and steers fed high levels of grain and without bulky. Rumen fluid from 32 cows, 50 steers and 50 calves fed on Brachiaria spp. and 20 steers with ruminal acidosis were collected. After decimal dilutions, the samples were inoculated on petri dishes with agar MacConkey at 39°C. Biochemical tests were used to identify the most common genera these bacteria. The concentration of these bacteria did not differ in the rumen of cows, calves and calves fed lignified tropical pasture and the most frequently identified genera for these animals were Escherichia, Enterobacter and Klebsiella. However, steers fed without forage and with acidosis showed a higher detection rate and larger population of these bacteria in the rumen (>6 log/ml) compared to steers fed only pasture. The Escherichia coli species was predominant among theses bacteria isolated from the rumen fluid of steers with acidosis (p<0.01). In beef zebu cattle raised on pasture lignified, the population of these microorganisms in the rumen is low showing greater diversity of genera. However in confined zebu steers fed without forage and with sub acute ruminal acidosis occur disequilibrium with increased E. coli population.

O objetivo deste estudo foi avaliar, por meio de meta-análise, a qualidade da carne de vacas de acordo com o genótipo, sistema de terminação e classe de idade ao abate. A partir de uma pesquisa na internet, foram identificados 15 artigos com informações relacionadas à qualidade da carne de vacas para abate. Os dados foram agrupados conforme o genótipo das vacas, sendo eles: definidos zebuínos ou continentais, cruzados zebuínos x britânicos ou zebuínos x continentais; conforme o sistema de terminação: confinamento ou pastagem; em relação à idade de abate, sendo ela: até 4 anos (jovem), de 4 a 8 anos (adulta) ou mais de 8 anos de idade (velha). A carne das vacas mestiças continentais foi mais macia que a dos demais genótipos, seja através do painel de avaliadores ou pelo Shear. A carne de vacas terminadas em confinamento demonstrou maior grau de marmorização em relação à carne das fêmeas terminadas em pastagem. A redução da idade de abate das vacas melhorou a coloração da carne. O genótipo das vacas afeta os aspectos organolépticos da carne enquanto o sistema de terminação e idade de abate afetam os aspectos sensoriais da carne.

The aim of this study was to evaluate, by meta-analysis, the quality of the meat of the cows according to genotype, termination system and age class slaughter. During an online research were identified 15 articles with information related to meat quality of slaughtered cows. The data were grouped according of the genotype of cows being: zebu or continental defined, crossed zebu x british or zebu x continental; according to termination system: feedlot or grassland; according to age of slaughter, where: up to 4 years old (young), 4-8 years old (adult) or more than 8 years old (old). The meat of the continental crossbred cows was softer than the other genotypes, both panel of evaluators and by Shear. The meat of cows finished in feedlot showed higher marbling degree in relation to meat of females finished on grassland. The reduction of the slaughter age of cows improved the meat color. The cow's genotype affects the organoleptic aspects of meat while the finished system and slaughter age affects the sensory aspects of meat.

O objetivo deste estudo foi investigar a associação entre alelos HLA, loci DQA1, DQB1 e DRB1, polimorfismos -168A/G e +1614G/C no gene CIITA, e suscetibilidade à esclerose múltipla (EM) em uma amostra de Rio de Janeiro, Brasil. Além disso, buscou-se determinar se alguma dessas associações pode ser gênero-dependente. Foram analisadas amostras de DNA de 52 pacientes com EM reincidente-remitente (EMRR) e 126 controles saudáveis pareados por sexo e idade. Foi identificada associação significativa HLA-DRB1*15:01-EMRR, que foi específica para o gênero feminino (Odds Ratio (OR) = 4,78, p = 0,001). Além disso, observou-se que o polimorfismo +1614 G/C, em combinação com o alelo HLA-DRB1*15:01 provoca o aumento da susceptibilidade à EM em pacientes do sexo feminino (OR = 4,55, p = 0,01). Juntos, estes resultados destacam a natureza poligênica da EM.

The objective of this study was to investigate the association between the HLA alleles at the DQA1, DQB1 and DRB1 loci, the CIITA genetic polymorphisms -168A/G and +1614G/C, and susceptibility to multiple sclerosis (MS) in a sample from Rio de Janeiro State, Brazil. Furthermore, we wished to determine whether any of these associations might be more significant in women compared with men. DNA samples from 52 relapsing-remitting MS (RRMS) patients and 126 healthy controls matched for sex and age were analyzed. We identified a significant HLA-DRB1*15:01-MS association that was female-specific (Odds Ratio (OR) = 4.78; p = 0.001). Furthermore, we observed that the +1614G/C mutation in combination with the HLA-DRB1*15:01 allele increased susceptibility to MS in females (OR = 4.55; p = 0.01). Together, these findings highlight the polygenic nature of MS.
