Food contamination is a public health problem, and the search for natural additives to increase food stability and safety is challenging. This research aimed to study nanoemulsions produced with coriander essential oil and kefiran, an exopolysaccharide extracted from kefir grains. The composition of coriander essential oil was evaluated, revealing linalool as the main component. An experimental design consisting of six trials was conducted. The NE2 formulation (0.5% kefiran and 1.5% coriander essential oil) exhibited smaller particle size, monodispersity, a lower centrifugal stability coefficient, and higher absolute zeta potential values (> 30 mV), indicating high electrical stability. Morphology, thermal stability, and toxicity tests were performed. The minimum bactericidal concentration was determined and applied to commercial cheese. Thermal stability tests demonstrated an increase in the stability of NE2 compared to its individual components, and it was also proven to be non-toxic. The concentration of 25% m v-1 was identified as the minimum bactericidal concentration and was applied to commercial cheese. problem challenging grains evaluated component conducted NE 0.5% 05 0 5 (0.5 15 1 1.5 size monodispersity coefficient > ( 3 mV, mV , mV) Morphology performed cheese components nontoxic. nontoxic non toxic. toxic non-toxic 25 v1 v v- 0.5 (0. 1. 2 0.

Lantana caatingensis Moldenke (Verbenaceae) is an endemic plant from northeastern Brazil. However, its chemical composition is almost unknown. This study aimed to characterize the chemical compounds found in L. caatingensis and investigate the antileishmanial potential of its hydroalcoholic extract and polar fractions. Compounds present in the hydroalcoholic extract obtained from L. caatingensis leaves and its polar fractions (ethyl acetate and methanolic) were analyzed by liquid chromatography with a photodiode-array detector coupled to electrospray ionization quadrupole time-of-flight mass spectrometry. An antileishmanial assay was performed in a 96-well plate against Leishmania major promastigotes using resazurin on a plate spectrophotometer and the results were expressed as percentage of growth inhibition. Nine compounds were determined in the investigated extract and fractions, classified as flavonoids, flavonoid C-glycosides and phenylethanoid glycosides. The antileishmanial activity revealed that the hydroalcoholic extract and the ethyl acetate fraction were active against L. major promastigotes with inhibitory concentration of 71.78 and 26.86 µg mL-1, respectively, while the methanolic fraction was inactive (478.40 µg mL-1). This is the first report on the chemical composition and antileishmanial activity of L. caatingensis extracts. These results contribute to further knowledge of species belonging to the Lantana genus.

Lisdexamfetamine is a prodrug that is converted to d-amphetamine in the body, mainly used to treat attention deficit hyperactivity disorder in children and adults. Its mechanism involves the enhancement of neurotransmitters such as norepinephrine and dopamine, which are critical for attention and behavioral regulation. With the upcoming patent expiration of Vyvanse®, bioanalytical methods for the quantification of lisdexamfetamine in plasma are needed for use in pharmacokinetic studies. In this work, we developed and validated a sensitive bioanalytical method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) for lisdexamfetamine quantification in human plasma. The method developed was performed for 4 min per sample and using the concentration range of 0.3-100 ng mL-1. Intra-batch, inter-batch and instrument reproducibility, the precision was lower than 10%. The results demonstrated that the method is rapid, sensitive, robust, and suitable for pharmacokinetic studies. damphetamine d amphetamine body adults dopamine regulation Vyvanse Vyvanse® studies work chromatographytandem chromatography tandem LCMS/MS LCMSMS LC MS/MS MS (LC-MS/MS 0.3100 03100 0.3 100 0 3 0.3-10 mL1. mL1 mL 1. 1 mL-1 Intrabatch, Intrabatch Intra batch, batch Intra-batch interbatch inter reproducibility 10 10% rapid robust LCMS MSMS 3100 0.310 0310 03 0. 0.3-1 mL- 310 0.31 031 0.3- 31

ABSTRACT Effects of abiotic stresses, such as high temperature, on plants are exacerbated by climate change. Lima beans exhibit higher tolerance to high temperatures than the common beans. Understanding the tolerance of lima bean landrace germplasm to high temperatures is important to improve their breeding. Therefore, in this study, we aimed to examine the high temperature responses of lima bean landrace varieties obtained from the Phaseolus Germplasm Bank at Universidade Federal do Piauí (BGP-UFPI, Brazil) in two environments. Five landraces showing the best performance in emission of flowers and number of pods formed (UFPI-945, UFPI1037, UFPI-876, UFPI-1036, and UFPI-1064) were evaluated in two cultivation environments, natural (29 ºC) and controlled (37 ºC), using a completely randomized design with four replications, with each plot consisting of a single plant. Analysis of variance and Tukey’s test (P < 0.05) were performed for 12 quantitative traits, followed by Pearson’s correlation analysis. Lima beans exhibited genetic variability in high temperature tolerance in both natural and controlled environments. Specifically, UFPI-1064 exhibited superior performance with higher pod thickness and width and number of flowers and lower flower and pod abortion than the other varieties in both natural and controlled environments. Pearson's correlation analysis revealed positive and strong correlations between the number of flowers and flower abortion in the natural environment and number of pods and seeds per pod in the controlled environment. stresses change breeding Therefore study BGPUFPI, BGPUFPI BGP UFPI, UFPI (BGP-UFPI Brazil environments UFPI945, UFPI945 945, 945 (UFPI-945 UFPI1037 UFPI876, UFPI876 876, 876 UFPI-876 UFPI1036, UFPI1036 1036, 1036 UFPI-1036 UFPI1064 1064 29 (2 ºC 37 (3 ºC, , replications plant Tukeys Tukey s P 0.05 005 0 05 1 traits Pearsons Pearson Specifically UFPI-106 UFPI94 94 (UFPI-94 UFPI103 UFPI87 87 UFPI-87 103 UFPI-103 UFPI106 106 2 ( 3 0.0 00 UFPI-10 UFPI9 9 (UFPI-9 UFPI10 UFPI8 8 UFPI-8 10 0.

ABSTRACT The objective of this study was to evaluate the agronomic performance and select biomass sorghum genotypes for growing in different regions of Brazil based on adaptability and stability analysis using the GGE biplot method. The 25 genotypes evaluated were from trials of value for cultivation and use (VCU) of biomass sorghum of the Brazilian Agricultural Research Corporation (Embrapa Maize and Sorghum) Breeding Program, conducted in eight locations across Brazil (Sobral, CE; Jaguariúna and Narandiba, SP; Nova Porteirinha and Sete Lagoas, MG; Planaltina, DF; Vilhena, RO; and Terra Rica, PR) during the 2021-2022 crop season. A randomized block experimental design with three replications was used. The following traits of were subjected to joint analysis of variance: plant height, flowering, and fresh and dry matter yields. The confirmation of genotype-by-environment interaction (G×E) was followed by adaptability and stability analysis using the GGE biplot method for all traits. The adjusted means were used to obtain the mean clustering using the Scott-Knott test (p < 0.05). Biomass sorghum genotypes showed a longer growth cycle, taller plants, and higher biomass yield than forage sorghum genotypes. The experimental sorghum hybrids 202129B014 and 202129B016 and the commercial hybrid BRS 716 can be recommended for fresh and dry matter production in all tested environments due to their high adaptability and stability. 2 VCU (VCU Embrapa Sorghum Program Sobral, Sobral (Sobral CE Narandiba SP Lagoas MG Planaltina DF Vilhena RO Rica PR 20212022 2021 2022 2021-202 season variance height flowering yields genotypebyenvironment genotype environment G×E GE G E (G×E ScottKnott Scott Knott p 0.05. 005 0.05 . 0 05 0.05) cycle plants B 202129B01 71 2021202 202 2021-20 00 0.0 202129B0 7 202120 20 2021-2 0. 202129B 20212 2021-

ABSTRACT The intensification of cattle post-weaning phase in tropical pastures depends on supplementation strategies. The objective of this study was to assess the effect of increasing levels of concentrate supplement on the intake, apparent digestibility of nutrients, feeding behavior, and performance of Girolando steers on tropical pasture during the post-weaning phase in the rainy season. Forty uncastrated male Girolando steers, initially weighing 266.62 ± 32.95 kg and aged 11 mo, were allocated into four concentrate supplement levels: 0.2%, 0.3%, 0.4%, and 0.5% body weight. The steers grazed on Urochloa brizantha (Hochst. ex A. Rich.) R.D. Webster ‘Marandu’ pasture. The intakes of supplement DM, non-fibrous carbohydrates (NFC), and total digestible nutrients increased linearly (P < 0.05) with the level of supplement offered to the steers. In a similar response, the apparent digestibility of DM and NFC from the diet also rose linearly (P < 0.05). Grazing time, total feeding time, and total chewing time decreased (P < 0.05) with the increasing levels of concentrate supplementation. In contrast, the time expended on feeding at the trough, biting rate, and the time taken to ruminate each cud increased (P < 0.05) with the supplementation level. Final body weight and average daily gain increased linearly (P < 0.05) with increasing concentrate supplementation. We recommend supplying concentrate supplement at a level of 0.5% of the body weight of steers on tropical pasture during the post-weaning phase in the rainy season.

Abstract Background: Chronic Chagas cardiomyopathy (CCC) is caused by an inflammatory process induced by Trypanosoma cruzi, which leads to myocarditis with reactive and reparative fibrosis. CCC progresses with myocardial perfusion abnormalities and histopathological events that affect cardiorespiratory fitness (CRF). Objectives: We evaluated the effects of aerobic physical training (APT) on myocardial perfusion and on morphological and functional impairments related with inflammation and fibrosis in Syrian hamsters with CCC. As a secondary objective, we analyzed the cross-sectional areas of the skeletal muscle. Methods: Hamsters with CCC and their respective controls were divided into four groups: CCC sedentary, CCC-APT, sedentary control and APT control. Seven months after infection, the animals underwent echocardiography, myocardial perfusion scintigraphy and cardiopulmonary exercise testing. Moderate-intensity APT was performed for fifty minutes, five times a week, for eight weeks. Subsequently, the animals were reassessed. Histopathological analysis was conducted after the above-mentioned procedures. The level of significance was set at 5% in all analyses (p<0.05). Results: CCC sedentary animals presented worse myocardial perfusion defects (MPD) over time, reduced left ventricle ejection fraction (LVEF) and showed more inflammation and fibrosis when compared to other groups (mixed ANOVA analysis). Conversely, APT was able to mitigate the progression of MPD, ameliorate inflammation and fibrosis and improve CRF efficiency in CCC-APT animals. Conclusions: Our study demonstrated that APT ameliorated cardiac dysfunction, MPD, and reduced inflammation and fibrosis in CCC hamster models. Additionally, CCC-SED animals presented skeletal muscle atrophy while CCC-APT animals showed preserved skeletal muscle CSA. Understanding APT's effects on CCC's pathophysiological dimensions is crucial for future research and therapeutic interventions. Background (CCC cruzi CRF. .

Resumo Fundamento: A Cardiomiopatia Chagásica Crônica (CCC) é causada por um processo inflamatório induzido pelo Trypanosoma cruzi, que leva à miocardite com fibrose reativa e reparativa. A CCC progride com alterações de perfusão miocárdica e eventos histopatológicos que afetam a Aptidão Cardiorrespiratória (ACR). Objetivos: Avaliamos os efeitos do Treinamento Físico Aeróbico (TFA) na perfusão miocárdica e nos comprometimentos morfológicos e funcionais relacionados à inflamação e fibrose em hamsters sírios com CCC. Como objetivo secundário, analisamos as áreas de secção transversa do músculo esquelético. Métodos: Hamsters com CCC e seus respectivos controles foram divididos em quatro grupos: CCC sedentário, CCC-TFA, controle sedentário e controle TFA. Sete meses após a infecção, os animais foram submetidos à ecocardiografia, à cintilografia de perfusão miocárdica e ao teste de esforço cardiopulmonar. TFA de intensidade moderada foi realizado durante cinquenta minutos, cinco vezes por semana, por oito semanas. Posteriormente, os animais foram reavaliados. A análise histopatológica foi realizada após os procedimentos acima mencionados. O nível de significância foi estabelecido em 5% em todas as análises (p<0,05). Resultados: Animais com CCC sedentários apresentaram piores Defeitos de Perfusão Miocárdica (DPM) ao longo do tempo, Fração de Ejeção do Ventrículo Esquerdo (FEVE) reduzida, e apresentaram mais inflamação e fibrose quando comparados aos demais grupos (análise ANOVA mista). Por outro lado, o TFA foi capaz de mitigar a progressão do DPM, atenuar a inflamação e a fibrose e melhorar a eficiência da ACR em animais CCC-TFA. Conclusão: Nosso estudo demonstrou que o TFA melhorou a disfunção cardíaca, DPM e reduziu a inflamação e a fibrose em modelos de hamster com CCC. Além disso, os animais CCC-SED apresentaram atrofia do músculo esquelético, enquanto os animais CCC-TFA apresentaram a AST do músculo esquelético preservada. Compreender os efeitos da TFA nas dimensões fisiopatológicas da CCC é crucial para futuras pesquisas e intervenções terapêuticas. Fundamento (CCC cruzi reparativa ACR. .

Abstract Objective: To build a model based on cardiometabolic indicators that allow the identification of overweight adolescents at higher risk of subclinical atherosclerotic disease (SAD). Methods: Cross-sectional study involving 161 adolescents with a body mass index ≥ + 1 z-Score, aged 10 to 19 years. Carotid intima-media complex thickness (IMT) was evaluated using ultrasound to assess subclinical atherosclerotic disease. Cardiometabolic indicators evaluated included nutritional status, central adiposity, blood pressure, lipidic profile, glycemic profile, as well as age and sex. Data was presented using measures of central tendency and dispersion, as well as absolute and relative frequency. The relationship between IMT measurement (outcome variable) and other variables (independent variables) was assessed using Pearson or Spearman correlation, followed by multiple regression modeling with Gamma distribution to analyze predictors of IMT. Statistical analysis was performed using SPSS and R software, considering a significance level of 5 %. Results: It was observed that 23.7 % had Carotid thickening, and the prevalence of abnormal fasting glucose was the lowest. Age and fasting glucose were identified as predictors of IMT increase, with IMT decreasing with age by approximately 1 % per year and increasing with glucose by around 0.24 % per mg/dL. Conclusion: The adolescent at higher risk is younger with higher fasting glycemia levels. Objective SAD. SAD .

ABSTRACT The need for studies that allow the use of brackish water in irrigated agriculture and the socioeconomic importance of melon cultivation in Brazil, especially for the Northeast region, which concentrates most of the national production and faces problems with the availability of good quality water for irrigation, motivated the present study. In this context, the objective of present study was to evaluate the growth, production and fruit quality of the ‘Goldex’ (yellow-type hybrid F1) melon under salt stress conditions. The experiment was performed in a completely randomized design, with two salinity levels of irrigation water (0.8 and 4.0 dS m-1) and eight evaluation times (52, 54, 56, 58, 60, 62, 64, and 66 days after transplanting). Variables of plant growth and development, production and quality of melon fruits were evaluated throughout the cycle. Plants had delayed growth characteristics and less development with the increase in irrigation water salinity, showing reductions of more than 20% in shoot dry weight, leaf area, number of branches and length of secondary branches and 16.7% in length of the main branch. In addition, salinity caused a delay in fruit development and a 16% reduction in final fruit weight, without significantly modifying carbohydrate and total soluble solids contents. Along the development, there was an increase in the total soluble solids content of the fruits, especially due to the increment of sucrose at the final stages of development.

RESUMO A necessidade de estudos que possibilitem a utilização de águas salobras na agricultura irrigada e a importância socioeconômica da cultura do melão no Brasil, especialmente para a região Nordeste, que concentra a maior parte da produção nacional e apresenta problemáticas com disponibilidade de água de boa qualidade para irrigação, norteou o presente estudo. Nesse contexto, o objetivo do presente estudo foi avaliar o crescimento das plantas, a produção e a qualidade de frutos do híbrido de melão amarelo ‘Goldex’ (híbrido F1 tipo amarelo) sob condições de estresse salino. A pesquisa foi conduzida em delineamento inteiramente casualizado, contendo dois níveis de salinidade da água de irrigação (0,8 e 4,0 dS m-1) e oito épocas de avaliação (52, 54, 56, 58, 60, 62, 64 e 66 dias após o transplantio). Foram avaliadas variáveis de crescimento e desenvolvimento das plantas, de produção e de qualidade dos frutos de melão ao longo do ciclo. As plantas tiveram as características de crescimento retardadas e menor desenvolvimento em função do aumento da salinidade da água de irrigação, apresentando redução superior a 20% para a o peso seco da parte aérea, área foliar, número de ramos, comprimento de ramos secundários e 16,7% para o comprimento do ramo principal. Além disso, a salinidade provocou atraso no desenvolvimento dos frutos e redução de 16% no seu peso final, sem modificar significativamente os teores de carboidratos e sólidos solúveis totais. Ao longo do desenvolvimento houve aumento no teor de sólidos solúveis totais dos frutos, especialmente em função do acréscimo de sacarose nos estádios finais de desenvolvimento.

ABSTRACT Objective: To define a reference chart comparing pressure drop vs. flow generated by a set of arterial cannulae currently utilized in cardiopulmonary bypass conditions in pediatric surgery. Methods: Cannulae from two manufacturers were selected considering their design and outer and inner diameters. Cannula performance was evaluated in terms of pressure drop vs. flow during simulated cardiopulmonary bypass conditions. The experimental circuits consisted of a Jostra HL-20 roller pump, a Quadrox-i pediatric oxygenator (Maquet Cardiopulmonary AG, Rastatt, Germany), and a custom pediatric tubing set. The circuit was primed with lactated Ringer’s solution only (first condition) and with human packed red blood cells added (second condition) to achieve a hematocrit of 30%. Cannula sizes 8 to 16 Fr were inserted into the cardiopulmonary bypass circuit with a “Y” connector. The flow was adjusted in 100 ml/min increments within typical flow ranges for each cannula. Pre-cannula and post-cannula pressures were measured to calculate the pressure drop. Results: Utilizing a pressure drop limit of 100 mmHg, our results suggest a recommended flow limit of 500, 900, 1400, 2600, and 3100 mL/min for Braile arterial cannulae sizes 8, 10, 12, 14, and 16 Fr, respectively. For Medtronic DLP arterial cannulae sizes 8, 10, 12, 14, and 16 Fr, the recommended flow limit is 600, 1100, 1700, 2700, and 3300 mL/min, respectively. Conclusion: This study reinforces discrepancies in pressure drop between cannulae of the same diameter supplied by different manufacturers and the importance of independent translational research to evaluate components’ performance.

En cuanto a la composición corporal, hubo diferencias significativas en la TFG debido al aumento de la masa magra en brazos de 6.441g a 7.014g (p=0,04), piernas de 16.379g a 17.281g (p=0,02) y cuerpo entero de 45.640g a 47.343g (p=0,01). En el GRM hubo una disminución significativa del porcentaje de grasa en los brazos de 23.160% a 20.750% (p = 0,04). Para la evaluación de la calidad de vida se utilizó el cuestionario WHOQOL-HIV-Bref, donde se encontró una mejoría significativa en todos los dominios, excepto en el dominio nivel de independencia. Conclusión: Concluimos que el entrenamiento de resistencia muscular es eficaz para aumentar la IL-10 y disminuir el porcentaje de grasa en los brazos, mientras que el entrenamiento de fuerza aumenta la masa magra total.

ABSTRACT Introduction: HIV/AIDS is considered one of the great cases of public health, but it is seen that patients who use antiretroviral therapy (ART) and practice strength training promote a promotion of their health. Objectives: Assess the impact of strength and resistance training on cytokines and body composition in people living with HIV/AIDS. Methods: Randomized clinical trial, the sample consisted of 12 patients, 7 from the Strength Group (GF) and 5 from Group 2, Muscular Resistance (MGR). We compared the levels of IL-2, IL-4, IL-6, IL-10 and TNF-α cytokines and body composition in the first and last sessions. The patients completed 36 strength and resistance training sessions over 12 weeks. Results: After 36 sessions of GRM resistance training, there was a significant increase from 4,734 pg/mL to 5,050 pg/mL of IL-10 (p=0.002). Regarding the GFR, no significant results were found. For body composition, there were significant differences in GFR due to the increase in lean mass of the arms from 6,441g to 7,014g (p=0.04), legs from 16,379g to 17,281g (p=0.02) and whole body of 45,640g to 47,343g (p=0.01). In G2 there was a significant decrease in the percentage of fat in the arms from 23,160% to 20,750% (p = 0.04). To assess quality of life, the WHOQOL-HIV-Bref questionnaire was used, where significant improvement was found in all domains, except for the level of independence domain. Conclusion: We conclude that muscular resistance training is effective in increasing IL-10 and decreasing the percentage of fat in the arms, whereas strength training increases lean mass in arms, legs, and the whole body.

RESUMO Introdução: O HIV/AIDS é considerado um dos grandes casos de saúde pública, porém verifica-se que pacientes que fazem uso de terapia antirretroviral (TARV) e praticam treinamento de força provocam uma promoção de sua saúde. Objetivos: Avaliar o impacto do treinamento de força sobre a resistência nas citocinas e a composição corporal de pessoas vivendo com HIV/AIDS. Métodos: Ensaio clínico randomizado, a amostra foi composta por 12 pacientes, sendo sete do Grupo Força (TFG) e cinco do Grupo Resistência Muscular (GRM). Comparou-se os níveis das citocinas IL-2, IL-4, IL-6, IL-10 e TNF-α e a composição corporal na primeira e na última sessão. Os pacientes completaram 36 sessões de treinamento de força e resistência ao longo de 12 semanas. Resultados: Após 36 sessões de treinamento resistido GRM, houve um aumento significativo de 4.734 pg/mL para 5.050 pg/mL de IL-10 (p=0,002). Em relação à TFG, não foram encontrados resultados significativos. Para composição corporal, houve diferenças significativas na TFG devido ao aumento da massa magra dos braços de 6.441g para 7.014g (p=0,04), pernas de 16.379g para 17.281g (p=0,02) e corpo inteiro de 45.640g para 47.343g (p=0,01). No GRM houve diminuição significativa do percentual de gordura nos braços de 23.160% para 20.750% (p = 0,04). Para avaliação da qualidade de vida foi utilizado o questionário WHOQOL-HIV-Bref, onde foi encontrada uma melhora significativa em todos os domínios, exceto no domínio nível de independência. Conclusão: Conclui-se que o treinamento de resistência muscular é eficaz em aumentar a IL-10 e diminuir o percentual de gordura nos braços, enquanto o treinamento de força aumenta a massa magra geral.

Resumo A atividade antioxidante do mel de Tetragonisca angustula (TAH) e seu extrato etanólico (TAEE) foram investigados. Os níveis totais de fenólicos (TPC) e flavonóides (TFC) também foram avaliados. Os resultados para TPC foram 19,91 ± 0,38 e 29,37 ± 1,82 mg GAE g-1 e para TFC 0,20 ± 0,02 e 0,14 ± 0,01 mg QE g-1 de TAH e TAEE, respectivamente. As atividades antioxidantes foram 73,29 ± 0,49% e 93,36 ± 0,27% no ensaio DPPH● e 71,73 ± 4,07% e 97,86 ± 0,35% no ABTS●+ para TAH e TAEE, respectivamente. A atividade redutora total foi determinada pelo método de poder redutor (PR) e íon ferrico (Fe III) e os resultados variaram em PR de 151,7 ± 25,7 e 230,7 ± 25,2 mg GAE L-1, para TAH e TAEE respectivamente e para (Fe III) em EC50 0,284 em TAEE e 0,687 em TAH. A análise química por HPLC-DAD do extrato etanólico (TAEE) revelou a presença de ácido ferúlico como componente majoritário no extrato. A análise de RMN 1H confirmou esta estrutura e mostrou a presença de glicose, ácido cítrico, ácido succínico, prolina e derivados de hidrocarbonetos no TAEE. Além disso, a origem botânica também foi investigada e apresentou característica multifloral, tendo encontrado 19 tipos polínicos com predomínio botânico da família Anacardiaceae, sendo o pólen Tapirira predominante (42,6%) e o Schinus secundário (25,7%). Os resultados mostraram que o mel de T. angustula é uma interessante fonte de compostos fenólicos antioxidantes devido à sua origem floral e pode atuar como protetor da saúde humana quando consumido.

Abstract The antioxidant activity of Tetragonisca angustula honey (TAH) and its ethanolic extract (TAEE) were investigated. The total levels of phenolic (TPC) and flavonoids (TFC) were also evaluated. The results for TPC were 19.91 ± 0.38 and 29.37 ± 1.82 mg GAE g-1 and for TFC 0.20 ± 0.02 and 0.14 ± 0.01 mg QE g-1 of TAH and TAEE, respectively. Antioxidant activities were 73.29 ± 0.49% and 93.36 ± 0.27% in the DPPH● assay and 71.73 ± 4.07% and 97.86 ± 0.35% in ABTS●+ for TAH and TAEE, respectively. The total reducing activity was determined by the method of reducing power (PR) and iron ion (Fe III) and the results varied in PR from 151.7 ± 25.7 and 230.7 ± 25.2 mg GAE L-1, for TAH and TAEE respectively and for (Fe III) in EC50 0.284 in TAEE and 0.687 in TAH. Chemical analysis by HPLC-DAD of the ethanolic extract (TAEE) revealed the presence of ferulic acid as majority phenolic component in the extract. The 1H NMR analysis confirmed this structure and showed the also presence of glucose, citric acid, succinic acid, proline and hydrocarbon derivatives. In addition, the botanical origin was also investigated and showed a multifloral characteristic, having found 19 pollen types with a botanical predominance of the Anacardiaceae family, with Tapirira pollen occurring as predominant (42.6%) and Schinus as secondary (25.7%). The results showed that T. angustula honey is an interesting source of antioxidant phenolic compounds due to its floral origin and can act as a protector of human health when consumed.

Resumo Este estudo objetivou analisar a dieta do cachorro-do-mato, de vida livre, por meio da identificação do conteúdo estomacal de 17 Cerdocyon thous atropelados em duas unidades de conservação da Floresta Amazônica. O conteúdo estomacal foi analisado e os itens alimentares foram quantificados pela frequência de ocorrência (FO) e percentagem de ocorrência (PO). Também foram avaliados os teores de matéria seca (MS), proteína bruta (PB), fibra bruta (FB), extrato etéreo (EE) e, matéria mineral (MM). Foram estimados o extrativo não-nitrogenado (ENN), a energia metabolizável (EM) e a necessidade energética de manutenção. A composição da dieta do cachorro-do-mato apresentou 29 itens alimentares dos diferentes grupos taxonômicos, tendo uma maior diversidade de itens de origem animal (n=22), ainda que a maior FO tenha sido de gramíneas (Poaceae) (41.18%). Dentre os itens de origem animal, 21% eram mamíferos, 18% répteis, 10% anfíbios, 9% invertebrados e 3% aves. Determinou-se um alto teor de FB (62.76%). A média do ENN e da MS foi 5.91% e 141.82 kcal/100g, respectivamente. A média da energia de manutenção foi 447.01 kcal/dia. Estes achados sugerem que o cachorro-do-mato encontrado na Bacia Amazônica é um animal generalista com uma dieta onívora, se alimentando de gramíneas, frutos, insetos, serpentes, anfíbios, aves e pequenos mamíferos, portanto com o mesmo hábito alimentar relatado a esta espécie quando encontrada em outros biomas brasileiros.

Abstract The present study aimed to evaluate the diet of the free-living crab-eating fox by identifying the stomach contents of the 17 crab-eating foxes (Cerdocyon thous) roadkilled in two conservation units, both located in the Amazon rainforest. The food items were quantified by frequency of occurrence (FO) and percentage of occurrence (PO). The stomach contents were analysed for dry matter (DM), crude protein (CP), crude fibre (CF), ether extract (EE), and mineral matter (MM). Nitrogen-free extractives (NFE), metabolisable energy (ME) values, as well as the energy need for maintenance were estimated. The composition of the diet for the crab-eating fox presented 29 food items from the different taxonomic groups, with a greater diversity of items of animal origin (n=22), although the highest frequency of occurrence was gramineae (Poaceae) (41.18%). Among the items of animal origin, 21% were mammals, 18% reptiles, 10% amphibians, 9% invertebrates and 3% birds. A high content of CF (62.76%) were determined. Nitrogen-free extractive and dry matter averages were 5.91% and 141.82 kcal/100g, respectively. The average maintenance energy was 447.01 kcal/day. These findings suggesting that the crab-eating foxes have a generalist diet with an omnivorous diet in the Amazon basin, feeding on gramineae, fruits, insects, snakes, amphibians, birds and small mammals and have the same feeding habit that present in other Brazilian biomes.
