Abstract Long-term-ecological-research (LTER) faces many challenges, including the difficulty of obtaining long-term funding, changes in research questions and sampling designs, keeping researchers collecting standardized data for many years, impediments to interactions with local people, and the difficulty of integrating the needs of local decision makers with “big science”. These issues result in a lack of universally accepted guidelines as to how research should be done and integrated among LTER sites. Here we discuss how the RAPELD (standardized field infrastructure system), can help deal with these issues as a complementary technique in LTER studies, allowing comparisons across landscapes and ecosystems and reducing sampling costs. RAPELD uses local surveys to understand broad spatial and temporal patterns while enhancing decision-making and training of researchers, local indigenous groups and traditional communities. Sampling of ecological data can be carried out by different researchers through standardized protocols, resulting in spatial data that can be used to answer temporal questions, and allow new questions to be investigated. Results can also be integrated into existing biodiversity networks. Integrated systems are the most efficient way to save resources, maximize results, and accumulate information that can be used in the face of the unknown unknowns upon which our future depends.

Abstract This article investigates how experiences of urban violence and police violence are associated with adolescents’ opinions regarding the legitimacy of the police. Data came from a survey with 724 participants born in 2005, residents of the city of São Paulo, Brazil. Direct and indirect effects of experiences of violence and police contact on adolescents’ evaluations of police were estimated by Structural Equation Modeling. Results indicate that aggressive and illegal policing, as well as exposure to violence in the neighborhood, erodes confidence in police legitimacy.

Resumo Este artigo busca compreender como a convivência com a violência urbana e a violência policial estão associadas às opiniões dos adolescentes em relação à legitimidade da autoridade policial. Utilizaram-se repostas a um inquérito com 724 participantes nascidos em 2005, moradores da cidade de São Paulo, Brasil. Os efeitos diretos e indiretos das experiências de violência e de contacto com a polícia sobre as avaliações em relação à polícia foram estimados por Modelagem de Equações Estruturais. Os resultados indicam que o policiamento agressivo e ilegal, assim como a exposição à violência no bairro, corroem a confiança na legitimidade policial.

Objective: To assess the adherence to a set of evidence-based recommendations to support mental health during the coronavirus disease 2019 (COVID-19) pandemic and its association with depressive and anxiety symptoms. Methods: A team of health workers and researchers prepared the recommendations, formatted into three volumes (1: COVID-19 prevention; 2: Healthy habits; 3: Biological clock and sleep). Participants were randomized to receive only Volume 1 (control), Volumes 1 and 2, Volumes 1 and 3, or all volumes. We used a convenience sample of Portuguese-speaking participants over age 18 years. An online survey consisting of sociodemographic and behavioral questionnaires and mental health instruments (Patient Health Questionnaire-9 [PHQ-9] and Generalized Anxiety Disorder-7 [GAD-7]) was administered. At 14 and 28 days later, participants were invited to complete follow-up surveys, which also included questions regarding adherence to the recommendations. A total of 409 participants completed the study – mostly young adult women holding university degrees. Results: The set of recommendations contained in Volumes 2 and 3 was effective in protecting mental health, as suggested by significant associations of adherence with PHQ-9 and GAD-7 scores (reflecting anxiety and depression symptoms, respectively). Conclusion: The recommendations developed in this study could be useful to prevent negative mental health effects in the context of the pandemic and beyond.

RESUMO O objetivo foi verificar o efeito de produtos fitossanitários via tratamento de sementes, antes e após o armazenamento, sobre o desempenho inicial da soja em condição de déficit hídrico no solo. O delineamento foi em blocos casualizados em esquema de parcelas subdivididas, com quatro repetições. A parcela principal foi constituída pela ausência e presença de déficit hídrico no solo, em um campo previamente cultivados. As subparcelas foram constituídas pelos tratamentos químicos fitossanitários de sementes: Abamectin + thiamethoxam + fludioxonil + metalaxyl-M + thiabendazole, Fipronil + pyraclostrobin + methyl thiophanate, Fludioxonil + metalaxyl-M + thiabendazole, Fludioxonil + metalaxyl-M, Tiofanato-metílico+Fluazinam, Carbendazim + tiram, Chlorantraniliprole, Acetamiprid, Fipronil, Thiamethoxam, Imidacloprid + thiodicarb e Controle (água). As avaliações da porcentagem de emergência, índice de velocidade de emergência, tempo médio de emergência e massa seca de plântulas foram realizadas logo após o tratamento fitossanitário e após seis meses de armazenamento das sementes tratadas. O desenvolvimento inicial das plântulas é prejudicado pelo déficit hídrico no solo, com potencial matricial médio de -26 kPa, à 5 cm, e -20 kPa à 10 cm de profundidade do solo. O tratamento de sementes com fungicidas favorece o desenvolvimento inicial de plântulas de soja, principalmente sob restrição hídrica no solo. O tratamento com inseticidas e nematicida e armazenamento das sementes por seis meses, afeta o vigor das sementes e desempenho inicial da cultura soja, com diferentes intensidades em função do ingrediente ativo.

ABSTRACT The effect of phytosanitary products on the initial performance of soybean crops under soil water deficit conditions was determined via seed treatment before and after storage. A randomized block design was used in a split-plot scheme with four replicates. Plots with and without soil water deficit were established in a previously cultivated field. The subplots consisted of the following phytosanitary chemical seed treatments: Abamectin + thiamethoxam + fludioxonil + metalaxyl-M + thiabendazole, Fipronil + pyraclostrobin + methyl thiophanate, Fludioxonil + metalaxyl-M + thiabendazole, Fludioxonil + metalaxyl-M, Tiofanato-metílico+Fluazinam, Carbendazim + tiram, Chlorantraniliprole, Acetamiprid, Fipronil, Thiamethoxam, Imidacloprid + thiodicarb, and a control (water). The emergence percentage, emergence speed index, mean emergence time, and seedling dry matter were evaluated immediately after phytosanitary treatment and after six months of storage for the treated seeds. Initial seedling development was impaired by soil water deficit, with a mean matric potential of -26 kPa at a soil depth of 5 cm and -20 kPa at 10 cm. The treatment of seeds with fungicides favored the initial development of soybean seedlings, especially under soil water restriction. It was determined that treatment with insecticidal and nematicides for six months in advance affects seed vigor and the initial performance of soybean crops with different intensities depending on the active ingredient.

RESUMO A manutenção da qualidade das sementes durante o armazenamento é premissa básica à eficiência produtiva. O objetivo deste trabalho foi avaliar o efeito da refrigeração no pré-embalamento das sementes e dos tipos de embalagem sobre a ocorrência de espécies fúngicas e as oscilações dessas populações ao longo do armazenamento de sementes de soja. Utilizou-se o delineamento experimental inteiramente casualizado com quatro repetições, em arranjo fatorial 2x3x5 envolvendo ou não a refrigeração da massa de sementes antes do embalamento, três tipos de embalagens e cinco períodos de armazenamento. A qualidade sanitária foi avaliada por meio do método de incubação em papel de filtro sem congelamento. A massa de sementes resfriadas a 13°C no pré-embalamento retorna à temperatura ambiente em 15 dias, em armazém com condições não controladas. O resfriamento no pré-envase não influencia na qualidade sanitária das sementes de soja durante o armazenamento, já a embalagem afeta. Ocorreram reduções na incidência de Phomopsis spp. e de Fusarium spp. no início do armazenamento, principalmente para sementes armazenadas em contêiner de polietileno (PEAD). A ocorrência de Cercospora kikuchii em ambos tipos de embalagem decresceu ao longo do armazenamento. Em todas as embalagens, as incidências de Aspergillus spp. e de Penicillium spp. aumentam ao longo do período de armazenamento.

ABSTRACT Maintaining seed quality during storage is a fundamental premise for production efficiency. The aim of this work was to evaluate the effect of cooling prior to packing seeds and of types of packaging on the occurrence of fungal species and the oscillations of these fungal populations over the storage period of soybean seeds. A completely randomized experimental design was used with four replications in a 2×3×5 factorial arrangement, consisting of cooling or no cooling of the seed mass before packing, three types of packaging materials, and five moments of evaluation during storage. Sanitary quality was evaluated by the method of incubation in filter paper without freezing. The seed mass cooled to 13°C prior to packing returned to ambient temperature in 15 days in a warehouse without controlled conditions. Cooling prior to packing does not affect the sanitary quality of soybean seeds during storage, whereas the type of packaging material does have an effect. The incidence of Phomopsis spp. and Fusarium spp. at the beginning of storage was lower mainly for seeds stored in the high-density polyethylene (HDPE) container. The occurrence of Cercospora kikuchii in both packaging types decreases over storage time. In all the packaging, the incidence of Aspergillus spp. and Penicillium spp. increases along the storage period.

SUMMARY Collision tumors are rare and may comprise components with different behavior, treatments, and prognosis. We report an unprecedented case of aggressive thyroid collision tumor containing widely invasive oncocytic carcinoma (OC), classical and hobnail (HPTC) variants of papillary carcinoma, and poorly differentiated carcinoma (PDTC). The patient underwent total thyroidectomy, radioactive iodine therapy, and within months progressed with local recurrence, and pulmonary metastases requiring neck dissection, external radiotherapy and systemic treatment with sorafenib. The rapid progression, dedifferentiated metastatic lesions, and failure to treatments resulted in the patient´s death. The great variety of histological types and the evolution of this case were a challenge for the management of metastatic disease. Widely invasive OC, HPTC and PDTC are considered to have a worse prognosis. HPTC has never been reported as a component of a collision tumor. HPTC and PDTC should call attention to a possible higher-grade transformation.

Abstract: En | Text: En | PDF: En

Fungi and bacteria are well-known pathogens for plants, fruits, and animals, including humans. In this context, the prospection of antimicrobial agents is crucial to provide new alternatives for the treatment of microbial diseases. Hence, selenium- and tellurium-containing compounds are underexploited and herein, antimicrobial activity of several organochalcogenated compounds was evaluated against Gram-negative and Gram-positive bacteria and fungi. A direct comparison between Se- and Te-containing compounds was performed, as well as structure-activity relationship studies. Among assayed compounds, secondary Se-amines LQ16 and LQ20 and secondary Te-amine LQ28 showed excellent results against a variety of fungi, while primary Te-amine LQ10 demonstrated promising results against bacteria. These results suggest organoselenides and organotellurides may be used for the development of new antimicrobial agents.

RESUMO Urbanização afeta a composição e funções ecossistêmicas das comunidades de morcegos em várias regiões do planeta. Entretanto, este ainda é um tema pouco explorado no Neotrópico. No Brasil, embora poucas cidades apresentem inventários de quirópteros, órgãos municipais de saúde pública (e.g., Centro de Controle de Zoonoses) realizam a vigilância passiva dos morcegos infectados pelo vírus da raiva. Estas instituições fazem a identificação dos espécimes oriundos principalmente de áreas urbanas e coletam dados biológicos importantes para o manejo ambiental, controle populacional, ecologia e conservação das espécies. O presente estudo analisou os dados de recebimento de morcegos, de 2001 a 2017, oriundos da cidade de Guarulhos, comparando as taxas de recebimento, frequência, riqueza e dominância das espécies com estudos prévios conduzidos em cidades brasileiras. Os dados da vigilância em saúde pública demonstraram uma alta riqueza de espécies (n = 29), representadas por três famílias mais comuns em áreas urbanas brasileiras (Phyllostomidae, Molossidae e Vespertilionidae). Molossus molossus (Pallas, 1766), Glossophaga soricina (Pallas, 1766) e Myotis nigricans (Schinz, 1821) representaram a maioria (70%) dos dados da quiropterofauna de Guarulhos. Esta dominância pode estar relacionada com a flexibilidade da dieta dessas espécies (insetívoras e nectarívoras não obrigatórias) e abrigos diurnos em edificações, recursos estes altamente disponíveis nas cidades brasileiras. Assim, para mitigar os efeitos da urbanização sobre a rica quiropterofauna regional, recomenda-se que o planejamento ambiental das cidades considere suas diretrizes urbanísticas e florísticas como uma ferramenta ao manejo integrado da fauna silvestre e saúde pública, além de implantar estratégias para aumentar o potencial de conservação da biodiversidade nestes ambientes.

ABSTRACT Urban bats from Guarulhos city: high species richness and dominance of ecologically bats revealed from the rabies monitoring data. Urbanization has impacted bat communities and their ecosystemic services in various regions of the world. However, this impact has been few studied in the Neotropic. In Brazil, although urban bat inventories are scarce, public health organs (e.g., Zoonoses Control Center) perform passive surveillance of infected bats by the rabies virus. These institutions carry out bat identification and collect biologic data essentials to the environment management, population control, ecology, and bat conservation. The present study analyzed bat data (from 2001 to 2017) recorded in Guarulhos city, which integers São Paulo metropolitan region. We compared bat receivement rate, richness, and dominance with other studies. The health surveillance data demonstrated high species richness (n = 29), represented by the three bat families most commonly recorded in Brazilian cities (Phyllostomidae, Molossidadae and Vespertilionidae). Molossus molossus (Pallas, 1766), Glossophaga soricina (Pallas, 1766) and Myotis nigricans (Schinz, 1821) represented most bat data (70%) from Guarulhos city. This dominance can be explained by the diet flexibility (insectivores and non-obligate nectarivores) and shelter occupation in buildings of these species, resources highly available in cities. The understood of the urban characteristics associated with urban bat dominance is important by the provide insights on how to mitigate the impacts of urbanization on the richest regional bat community. Thus, it is recommended that citiesʼ environmental planning consider urbanistic and floristic guidelines as a tool integrated for wild life and public health management, and implement strategies to increase the conservation potential in urban ecosystems.

Abstract Phytochemical studies of Cespedesia spathulata (Ochnaceae) leaves using 1H, 13C NMR, and GC-MS have led to the isolation of some metabolites identified for the first time in these species such as cathechin, epicatechin, vitexin, orientin, 6’’-O-acetyl-vitexin, sitosterol, stigmasterol, phytol, 4,5-dihydrovomifoliol and a mixture of aliphatic methyl esters, together with ochnaflavone, which was previously isolated from this plant. The modulating activity of some fractions and compounds from Cespedesia spathulata towards tyrosinase enzyme was assayed by spectroscopic and theoretical means/experiments. The dichloromethane fraction (133 μg mL-1) and ochnaflavone (333 μM) inhibited tyrosinase activity by 20 % and 2.0 %, respectively, whereas the ethyl acetate fraction (666 μg mL-1) and ±catechins (catechin and epicatechin - 800 μM) activated it by 104 % and 384 %, respectively. Quantum chemical calculations suggested that catechin and epicatechin are better activators than L-DOPA by interacting with Cu (II) ions. Molecular docking results suggested that hydrogen bonding and hydrophobic interactions are the main binding forces between each tyrosinase activator and the amino acid residues inside the active protein binding pocket.

Resumo Este estudo teve como objetivo caracterizar quimicamente os óleos essenciais (OE) de Cinnamomum zeylanicum (canela) e Eremanthus erythropappus (candeia) e avaliar sua atividade acaricida, juntamente com a de seus principais compostos e do derivado de acetato de cinamila, sobre Rhipicephalus microplus. Os compostos do óleo essencial foram identificados por cromatografia gasosa. Foram realizados o Teste de Pacote de Larvas (TPL), em concentrações variando de 0,31 a 10,0 mg/mL, e o Teste de Imersão de Adultos (TIA), em concentrações entre 2,5 e 60,0 mg/mL. (E)-cinnamaldeído e α-bisabolol foram os principais compostos nos OE da canela (86,93%) e da candeia (78,41%), respectivamente. No TPL, os OEs de canela e candeia, e os compostos (E)-cinnamaldeído, α-bisabolol e acetato de cinamila resultaram em 100% de mortalidade nas concentrações de 2,5, 2,5, 5,0, 10,0 e 10,0 mg/mL, respectivamente. No TIA, valores percentuais de controle >95% foram observados para OE de canela e candeia, (E)-cinnamaldeído e α-bisabolol nas concentrações de 5,0, 60,0, 20,0 e 20,0 mg/mL, respectivamente, enquanto o acetato de cinamila apresentou baixa atividade. Conclui-se que os OEs e seus compostos apresentaram alta atividade acaricida, enquanto o derivado acetilado do (E)-cinnamaldeído apresentou menor atividade acaricida em fêmeas ingurgitadas de R. microplus.

Abstract This study aimed to chemically characterize the essential oils (EOs) of Cinnamomum zeylanicum (cinnamon) and Eremanthus erythropappus (candeia) and evaluate their acaricidal activity, together with that of their major compounds and cinnamyl acetate derivative, against Rhipicephalus microplus. Essential oil compounds were identified through gas chromatography. The larval packet test (LPT) at concentrations ranging from 0.31 to 10.0 mg/mL and the adult immersion test (AIT) at concentrations between 2.5 and 60.0 mg/mL were performed. (E)-cinnamaldehyde and α-bisabolol were the major compounds in cinnamon (86.93%) and candeia (78.41%) EOs, respectively. In the LPT, the EOs of cinnamon and candeia and the compounds (E)-cinnamaldehyde, α-bisabolol and cinnamyl acetate resulted in 100% mortality at concentrations of 2.5, 2.5, 5.0, 10.0 and 10.0 mg/mL respectively. In the AIT, percentage control values > 95% were observed for cinnamon and candeia EOs, (E)-cinnamaldehyde and α-bisabolol at the concentrations of 5.0, 60.0, 20.0, and 20.0 mg/mL, respectively, whereas cinnamyl acetate showed low activity. We conclude that EOs and their compounds showed high acaricidal activity, whereas the acetylated derivative of (E)-cinnamaldehyde presented less acaricidal activity on R. microplus engorged females.

RESUMO Uma das possíveis alternativas para potencializar a utilização de recursos hídricos é a utilização de polímeros hidrorretentores. Objetivou-se avaliar como níveis de irrigação e doses de solução hidrorretentora interferem na produção da alface crespa, cultivar Vanda. O experimento foi realizado de dezembro de 2017 a janeiro de 2018, sob canteiros em ambiente protegido na área experimental do Instituto Federal Goiano - Campus Urutaí, GO (17º 29’ 10” S de latitude, 48º 12’ 38” O de longitude e 697 m de altitude). Testaram-se quatro níveis de irrigação (50, 75, 100 e 125%) da evaporação obtida diariamente pelo micrômetro de gancho e cinco doses de solução de hidrogel (0, 50, 100 e 200 g planta-1). Utilizou-se o delineamento de blocos ao acaso e esquema de parcelas subdivididas e quatro blocos. Foram avaliadas massa fresca da parte aérea, massa seca da parte aérea, altura de plantas, número de folhas e produtividade. Verificou-se incremento de 29,24% da massa seca da parte aérea comparando as doses de solução hidrorretentora de 0 e 169,28 g e acréscimo de 14,36% da altura de plantas quando comparados os níveis de irrigação de 50 e 125%. O uso de solução hidrorretentora proporciona aumento significativo em todos os parâmetros produtivos avaliados. Os níveis de irrigação utilizados influenciam as variáveis massa fresca da parte aérea, altura de planta e produtividade. A produtividade aumentou 18,42% para os níveis de irrigação utilizados, e os maiores valores estimados foram com a dose de solução hidrorretentora de 157,49 g (14,46 t ha-1).

ABSTRACT One of the potential alternatives to improve the use of water resources is the use of hydro retainer polymer applied to the soil. The objective of this study was to evaluate how irrigation levels and doses of hydro retainer polymer interfere in the production of ’Vanda’ lettuce. The experiment was carried out from December 2017 to January 2018 under protected environment in the Instituto Federal Goiano, Urutaí Campus, Goiás State, GO, Brazil (17º 29’ 10” S of latitude, 48º 12’ 38” W of longitude and 697 m of altitude). The work tested four irrigation levels of 50, 75, 100 and 125% of the evaporation obtained daily by the hook micrometer and five doses of hydrogel polymer (0, 50, 100, 150 and 200 g plant-1). The experimental design was a randomized block design in a scheme of split-plot and four blocks. Canopy fresh and dry mass, plant height, number of leaves and productivity were evaluated. There was 29.24% increase in the dry mass comparing the hydro retainer polymer doses of 0 and 169.28 g and an increase of 14.36% of the height of plants when compared with the irrigation levels of 50 and 125%. The use of a hydro retainer polymer provided a significant increase in all the evaluated productive variables. The irrigation levels influence the fresh mass from aerial part, plant height and productivity. The productivity increased 18.42% for the irrigation levels used and the highest estimated values were presented in the dose of 157.49 g (14.46 t ha-1) hydro retainer polymer.

Abstract: En | Text: En | PDF: En

Objective: The Parenting Styles and Dimensions Questionnaire (PSDQ) is used worldwide to assess three styles (authoritative, authoritarian, and permissive) and seven dimensions of parenting. In this study, we adapted the short version of the PSDQ for use in Brazil and investigated its validity and reliability. Methods: Participants were 451 mothers of children aged 3 to 18 years, though sample size varied with analyses. The translation and adaptation of the PSDQ followed a rigorous methodological approach. Then, we investigated the content, criterion, and construct validity of the adapted instrument. Results: The scale content validity index (S-CVI) was considered adequate (0.97). There was evidence of internal validity, with the PSDQ dimensions showing strong correlations with their higher-order parenting styles. Confirmatory factor analysis endorsed the three-factor, second-order solution (i.e., three styles consisting of seven dimensions). The PSDQ showed convergent validity with the validated Brazilian version of the Parenting Styles Inventory (Inventário de Estilos Parentais – IEP), as well as external validity, as it was associated with several instruments measuring sociodemographic and behavioral/emotional-problem variables. Conclusion: The PSDQ is an effective and reliable psychometric instrument to assess childrearing strategies according to Baumrind’s model of parenting styles.

Abstract: En | Text: En | PDF: En

This work presents a simple and fast method for colchicine (CO) determination in pharmaceutical formulations and urine by multiple pulse amperometry (MPA) with flow injection analysis (FIA) system using a boron-doped diamond electrode. In optimized conditions, it was possible to quantify CO in urine samples without interference of uric acid and ascorbic acid. The working linear range for CO quantification was achieved from 1.0 × 10-7 to 0.5 × 10-3mol L-1 with a low limit of detection of 2.14 × 10-8mol L-1. Furthermore, the proposed method showed high repeatability for 10 consecutive injections of 1.0 × 10-4mol L-1 CO (relative standard deviation = 1.28%) and good analytical frequency (30 determinations per hour). The addition and recovery studies in all pharmaceutical samples were approximately 100% and the results for CO determination were compared by high performance liquid chromatography (HPLC) with UV detection.

Abstract: En | Text: En | PDF: En

This study reports the optimization of geranyl butanoate production by esterification of geraniol and butanoic acid in a solvent-free system using two immobilized lipases as catalyst. The operating conditions that optimized geranyl butanoate production were determined to be 40 °C, a geraniol to butanoic acid molar ratio of 3:1, 150 rpm, 5 wt% of enzyme, and 1 h of reaction, which resulted in a reaction conversion of about 97% for Novozyme 435. When homemade Novozyme NZL-102-LYO-HQ (Cal-B) immobilized in polyurethane foam was used as catalyst, the experimental conditions of an alcohol to acid molar ratio of 5:1, 70 °C, 150 rpm, 5 wt% of enzyme, and 1 h of reaction gave a conversion of 95%. New experimental data on enzymatic esterification of geraniol and butanoic acid for geranyl butanoate production are reported in this work, showing that the technique is promising for overcoming the well-known drawbacks of the chemical-catalyzed route.

RESUMO: Recentemente, glutamina e β-glucano têm demonstrado desempenhar um papel importante na modulação do sistema imune e na promoção de benefícios para a saúde intestinal. O objetivo deste estudo foi investigar o efeito dessa intervenção sobre as respostas inflamatórias e saúde intestinal de camundongos pré- tratados por via oral com 1,3/1,6-β-glucano (80mg/kg) derivado de Saccharomyces cerevisiae com ou sem glutamina (150mg/kg) e posteriormente desafiados com citarabina (Ara-C) (15mg/kg). Melhoras em vilosidades e criptas não foram observadas no grupo de tratamento com β-glucano. A morfometria intestinal no grupo de tratamento com glutamina apresentou os melhores resultados. O grupo em que foi utilizado β-glucano em combinação com glutamina apresentou os maiores valores de IL-1β e IL -10 e valores mais baixos para os leucócitos e INF-γ. Com base nestes resultados, o pré-tratamento de β-glucano combinado com glutamina reduziu a inflamação intestinal e melhorou a resposta imune após o desafio com Ara-C.

ABSTRACT: Recently, glutamine and β-glucan have been demonstrated to play an important role in modulation of the immune system and in promoting intestinal health benefits. The aim of this study was to investigate the effect of this intervention on inflammatory responses and intestinal health in mice orally pretreated with soluble Saccharomyces cerevisiae derived 1,3/1,6-β-glucan (80mg/kg) with or without glutamine (150mg/kg) and then challenged with cytarabine (Ara-C) (15mg/kg). Improvements in villi and crypts were not observed in the β-glucan group. The intestinal morphometry in the glutamine group showed the best results. β-glucan in combination with glutamine presented the highest values of IL-1β and IL-10 and lowest values for leukocytes and INF-γ. Based on these results, combined β-glucan and glutamine pretreatment reduced intestinal inflammation and improved the immune response after Ara-C challenge.
