Abstract Introduction: Multicenter research initiatives in Brazilian dialysis centers are scarce. We described the recruitment and implementation phases of the SARC-HD study, aimed at investigating sarcopenia and its impact on adverse clinical outcomes. Methods: The SARC-HD is a cohort study being conducted with patients on hemodialysis in Brazil. The recruitment phase was defined as the period from the invitation to the center until the start of patient enrollment, whereas the implementation phase lasted from then until the completion of enrollment and baseline data collection. Upon implementation, a structured questionnaire was distributed to collect feedback from principal investigators. Results: 21 centers from three Brazilian regions consented to participate, with two dropping out. Ten principal investigators oversaw the 19 sites. Nine centers (47%) were funded entirely by health insurance companies. A total of 1525 patients were screened for eligibility and 1008 were enrolled, with a 66.1% recruitment rate. Recruitment and baseline data collection took 12 [interquartile range: 5–15] weeks. Qualitative content analysis identified barriers such as a lack of infrastructure and logistics for research. Facilitators included the management and organization of the steering committee. Data collection challenges were mainly reported with the subjective 7-point global assessment and the international physical activity questionnaire. The main challenge for the ongoing maintenance phase will be the lack of standardized information in electronic health records. Conclusions: The recruitment and implementation phases of the multicenter SARC-HD study were feasible. Barriers and facilitators identified by principal investigators may help future multicenter initiatives to integrate research-related tasks into clinical routine, facilitating successful experiences.

Resumo Introdução: Pesquisa multicêntrica em centros de diálise brasileiros são escassas. Descrevemos as fases de recrutamento e implementação do estudo SARC-HD, visando investigar a sarcopenia e seu impacto em desfechos clínicos adversos. Métodos: O SARC-HD é um estudo de coorte realizado com pacientes em hemodiálise no Brasil. A fase de recrutamento foi considerada o período entre convite ao centro e início da inclusão de pacientes, enquanto a fase de implementação durou a partir de então até a conclusão do recrutamento e coleta de dados basais. Após a implementação, um questionário estruturado foi distribuído para coletar feedback dos principais pesquisadores. Resultados: 21 centros de três regiões brasileiras consentiram em participar, com duas desistências. Dez pesquisadores principais supervisionaram 19 locais. Nove centros (47%) eram totalmente financiados por planos de saúde. 1525 pacientes foram avaliados para elegibilidade e 1008 foram incluídos, com taxa de recrutamento de 66,1%. Recrutamento e coleta de dados basais levaram 12 semanas [intervalo interquartil: 5–15]. A análise qualitativa de conteúdo identificou barreiras como falta de infraestrutura e logística para pesquisa. Os facilitadores incluíram gestão e organização do comitê gestor. Os desafios da coleta de dados foram relatados principalmente quanto à avaliação global subjetiva de 7 pontos e o questionário internacional de atividade física. O principal desafio para a fase de manutenção será a falta de informações padronizadas nos prontuários eletrônicos. Conclusões: As fases de recrutamento e implementação do estudo multicêntrico SARC-HD foram viáveis. Barreiras e facilitadores identificados pelos pesquisadores principais podem auxiliar futuras iniciativas multicêntricas a integrar tarefas relacionadas à pesquisa na rotina clínica, facilitando experiências bem-sucedidas.

ABSTRACT Integrated management is considered the best strategy to mitigate the damage caused by plant-parasitic nematodes. However, there is still limited information regarding some integrated techniques. Thus, this study aimed to assess the effects of genetic management associated with chemical control of Meloidogyne javanica in soybean (Glycine max (L.) Merr.) The experiment was installed in a greenhouse according to an 8×4 factorial design with eight replicates. The first factor was soybean cultivar (HO Juruena IPRO, resistant; Foco IPRO, HO Maracaí IPRO, and CZ 58B28 IPRO, moderately resistant; HO Mamoré IPRO, moderately susceptible; and Extrema IPRO, CZ 48B32 IPRO, and HO Aporé IPRO, susceptible). The second factor consisted of an untreated control and commercial nematicides based on abamectin, thiodicarb+imidacloprid, and fluopyram. Plants were inoculated with 2000 nematode eggs, and nematode and vegetative variables were evaluated at 65 d after inoculation. There was an interaction effect on nematode variables. Furthermore, there was an additive effect of genetic management and chemical control, mainly in resistant cultivars treated with thiodicarb+imidacloprid or fluopyram with controls of up to 69.90% and 96.86%, respectively. The application of fluopyram and the use of ‘HO Juruena IPRO’, ‘Foco IPRO’, or ‘HO Maracaí IPRO’ also contributed to the control of M. javanica. Vegetative variables were studied by analyzing product effects separately, but results were inconclusive.

ABSTRACT This study used a pedigree analysis to monitor trends in the genetic structure of the Mangalarga breed and identify factors that could impact its genetic variability. For this, genealogical information was used from the Associação Brasileira dos Criadores de Cavalo da Raça Mangalarga, considering as total population (TP) the animals born between 1919 and 2018 (n = 206,426) and as reference population (RP) those born between 2009 and 2018 (n = 20,539), which is the most recent generation according to the average generation interval calculated for the breed of 9.37 years. We evaluated the number of male and female births per year, foals produced by Mangalarga breeding animals, using the ENDOG 4.8, generation interval, proportion of known ancestors per parental generation, number of equivalent generations known per animal, inbreeding coefficient, increase in inbreeding, average relatedness (AR), effective population size, effective number of founders, effective number of ancestors, and founder genome equivalent. The number of equivalent generations known per animal increased over time, reaching an average of 2.75 in TP and 4.88 in RP. The calculated F was 2.26% for TP and 5.57% for RP, while AR was 2.41% for TP and 4.10% for RP. The effective population size was 40.85 for TP and 38.89 for RP. The 206,426 registered Mangalarga horses (TP) were derived from the genetic contribution of 9,011 founders and 8,908 ancestors, whereas those registered in or after 2009 (RP) originated from 2,662 founders and 2,193 ancestors. The effective number of founders represented 1.11 and 1.35% of the total number of founders in TP and RP, respectively. For RP, 11 animals accounted for 29.21% of the genetic pool of the breed. The analysis of population parameters estimated in the present study indicates that the Mangalarga horse population was formed through uneven contributions from founders and ancestors; therefore, genetic management of the breed is required to restrict average inbreeding from increasing over generations. variability this (TP 191 201 n 206426 206 426 RP (RP 200 20,539, 20539 20,539 , 20 539 20,539) 937 9 37 9.3 years year 48 4 8 4.8 coefficient AR, (AR) time 275 2 75 2.7 488 88 226 26 2.26 557 5 57 5.57 241 41 2.41 410 10 4.10 4085 40 85 40.8 3889 38 89 38.8 206,42 9011 011 9,01 8908 908 8,90 2662 662 2,66 2193 193 2,19 111 1 1.1 135 35 1.35 respectively 2921 29 21 29.21 therefore 19 20642 42 2053 20,53 53 93 3 9. 4.

The present study optimized the extraction process of bioactive compounds present in ginger (Zingiber officinale) dried at 80 °C, using ethanol:water 70:30 (v/v) as solvent. The extracts were evaluated for antioxidant activity by the 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical reduction methods and by the chelating activity of FeII ions. It was found that the extraction condition with a temperature of 60 °C and an extraction time of 12 h showed better responses to the tests. Then, the characterization of the compounds was carried out by mass spectrometry and thermal analysis (thermogravimetric (TG), differential thermal analysis (DTA), and differential scanning calorimetry (DSC)), identifying that the main compounds of ginger were gingerols and shogaols, being confirmed by the intensities and characteristics of the thermal graphs. The inhibition of the enzyme acetylcholinesterase (AChE) was evaluated using the Ellman test, which did not show an inhibitory action. Regarding cytotoxic activity, the free extract and encapsulated in liposomes were tested, showing antiproliferative effect at different concentrations for human kidney tumor cells (786-0), liver cells (HUH7.5), and Macaca mullata normal kidney cells (LLC-MK2). Given the results obtained, ginger presents itself as a renewable source of bioactive compounds and can be indicated for applications in the pharmaceutical industry.

ABSTRACT This experiment was carried out to evaluate the effects of organic acids on the intestinal integrity and productive performance of broiler chickens experimentally inoculated with Salmonella Enteritidis. Additionally, Salmonella colonization levels in internal organs were evaluated. The study included 576 one-day-old CobbTM male broilers, distributed into eight treatment groups and six replicates. A completely randomized experimental design (encapsulated butyric acid × inoculation by Salmonella Enteritidis) was used. Poultry was orally inoculated with Salmonella Enteritidis in the first day (0 or 2.0 × 106 CFU/mL) and after 22 days of age (0 or 1.0 × 109 CFU/ mL). The butyric acid was added to the feed in different concentration (treatments 0.03, 0.075, and 0.15%), and the chickens were raised up to 42 days old. Encapsulated butyric acid at 0.03% increased the body weight gain and the average weight of the chickens up to 21 days old. After 14 days old, the butyric acid had a positive effect on jejunum villus. Encapsulated butyric acid at 0.03% in feed improves the performance and intestinal integrity of chickens.

Abstract: Eugenia klotzschiana, commonly known as pêra-do-cerrado, belongs to the Myrtaceae family. It is an unconventional food plant that is exploited in an extractive manner. The purpose of this study was to investigate the germination behavior of E. klotzschiana O. Berg seeds and their sensitivity to desiccation. The seeds were manually pulped from the fruits and stored in plastic containers. The initial water content was subsequently determined using the oven method at 105°C for 24 hours, yielding a value of 46.6%. Sub-samples were then separated to obtain the desired water contents of 40%, 32%, 22%, and 15% for treatments 2, 3, 4, and 5. The data underwent analysis of variance (ANOVA) and, if significant by the F test (p<0.05), the means were compared using the T test. Graphs with 95% confidence intervals were generated to illustrate the comparisons. The seedling development data was arranged in a box plot. The R software was used for these analyses. The data analysis revealed that E. klotzschiana O. Berg seeds do not have the potential to germinate with a water content lower than 22.50% moisture. Furthermore, the water content with the highest percentage, 46.6%, resulted in 100% germination.

RESUMO A ação de insetos-praga afeta diretamente a produtividade agrícola, demandando assim grande quantidade de aplicações de inseticidas para o controle dos mesmos. Os principais produtos utilizados são advindos dos grupos organofosforados, piretróides e espinosinas, no entanto, o uso indiscriminado desses produtos pode gerar efeitos negativos, principalmente aos organismos do solo. Com isso, objetivou-se neste estudo avaliar as alterações sofridas pela macrofauna do solo provocada pela aplicação de inseticidas em área de produção frutífera. Os inseticidas malationa, deltametrina e espinetoram, foram aplicados na dosagem máxima indicada pelo fabricante, utilizando-se o dobro do volume de calda para aplicações terrestres. O delineamento experimental ocorreu em blocos ao acaso, constituído por quatro tratamentos com cinco repetições cada, distribuídas em cinco blocos. Após a aplicação, a macrofauna do solo foi avaliada de acordo com o método Tropical Soil Biology and Fertility (TSBF). Foi realizada a quantificação e identificação dos indivíduos por grupos taxonômicos, para posterior determinação da densidade, riqueza, índices de diversidade de Shannon-Weaver (H') e equabilidade de Pielou (J’). Constatou-se que malationa, deltametrina e espinetoram não afetaram a densidade total, assim como a densidade por grupo grupos taxonômicos, exceto o grupo Coleoptera que apresentou menor densidade de indivíduos por m2 em solo tratado com malationa e deltametrina, diferindo dos solos tratados com o inseticida espinetoram e ao tratamento controle. Portanto, constata-se que aplicações de deltametrina reduzem a densidade de Coleoptera do solo, sob as condições testadas. insetospraga insetos praga agrícola mesmos organofosforados espinosinas entanto negativos isso objetivouse objetivou se frutífera fabricante utilizandose utilizando terrestres acaso cada TSBF.

ABSTRACT The action of pest insects directly affects agricultural productivity, thus requiring a large number of insecticide applications for their control. The main products used come from the organophosphate, pyrethroid and spinosyn groups, but indiscriminate use of these products can cause negative effects, especially on soil organisms. Thus, the objective of this study was to evaluate changes in soil macrofauna caused by the application of insecticides in a fruit production area. The insecticides malathion, deltamethrin and spinetoram were applied at the maximum dose indicated by the manufacturer, using twice the volume of solution for terrestrial applications. The experimental design was randomized blocks, consisting of four treatments with five replicates each, distributed in five blocks. After application, soil macrofauna was evaluated according to the Tropical Soil Biology and Fertility (TSBF) method. Individuals were quantified and identified by taxonomic groups for further determination of density, richness, Shannon-Weaver diversity index (H') and Pielou evenness index (J’). Malathion, deltamethrin and spinetoram did not affect the total density, as well as the density per taxonomic group, except for the Coleoptera group, which had lower density of individuals per m2 in soil treated with malathion and deltamethrin, differing from the soils treated with spinetoram and from the control treatment. Therefore, it is found that deltamethrin applications reduce the density of Coleoptera in the soil under the conditions tested. productivity organophosphate effects organisms Thus area manufacturer blocks each TSBF (TSBF method richness ShannonWeaver Shannon Weaver H (H' J.

RESUMO A arara-azul-de-lear (Anodorhynchus leari Bonaparte, 1856) é um psitacídeo brasileiro globalmente ameaçado de extinção. Apesar de seu status de ameaça (em perigo), há escassez de estudos sobre seu comportamento. Compreender o comportamento desta espécie é crucial para evitar imprecisões nas estratégias de manejo e conservação. Este estudo teve como objetivo delinear o repertório comportamental de indivíduos de arara-azul-de-lear residentes na Fundação Parque Zoológico de São Paulo sob duas condições distintas: pareados e em flocking. De setembro de 2014 a fevereiro de 2016, conduzimos observações diretas utilizando amostragem de todas as ocorrências. Foi compilado um etograma abrangendo 65 atos comportamentais categorizados em dez grupos: manutenção, descanso, locomoção, exploração, alimentação, vigilância, comportamentos sócio-agonísticos, sócio-afiliativos, reprodução e comportamentos estereotipados. Além disso, seis vocalizações foram identificadas com base em espectrogramas e associadas a contextos comportamentais específicos: alarme, contato, coesão de pares, reprodução e imitação. Esses resultados fornecem uma visão abrangente do comportamento da arara-azul-de-lear em cativeiro. As descrições do etograma e das vocalizações servem como recurso fundamental para estudos futuros, facilitando o refinamento das ferramentas empregadas nos esforços de conservação desta espécie. araraazuldelear arara azul lear Anodorhynchus Bonaparte 1856 extinção perigo, perigo , perigo) distintas flocking 201 2016 ocorrências 6 grupos manutenção descanso locomoção exploração alimentação vigilância sócioagonísticos, sócioagonísticos sócio agonísticos, agonísticos sócio-agonísticos sócioafiliativos, sócioafiliativos afiliativos, afiliativos sócio-afiliativos estereotipados disso específicos alarme contato pares imitação cativeiro futuros 185 20 18 2 1

ABSTRACT The Lear’s Macaw (Anodorhynchus leari Bonaparte, 1856) is a Brazilian parrot globally threatened by extinction. Despite its threatened status (endangered), there is a scarcity of studies on its behavior. Understanding the behavior of this species is crucial to prevent inaccuracies in management and conservation strategies. This study aimed to delineate the behavioral repertoire of Lear’s Macaw individuals residing at the Fundação Parque Zoológico de São Paulo under two distinct conditions: paired and in flocking. From September 2014 to February 2016, we conducted direct observations using all-occurrences sampling. An ethogram was compiled, encompassing 65 behavioral acts categorized into ten groups: maintenance, rest, locomotion, exploration, feeding, vigilance, socio-agonistic, socio-affiliative, reproduction, and stereotypic behaviors. Additionally, six vocalizations were identified based on spectrograms and associated with specific behavioral contexts: alarm, contact, pair cohesion, reproduction, and imitation. These findings provide a comprehensive overview of Lear’s Macaw behavior in captivity. The ethogram and vocalization descriptions serve as a foundational resource for future studies, facilitating the refinement of tools employed in the conservation efforts for this species.

Resumo O aumento da modificação dos habitats e da perda de espécies demanda esforços consistentes para descrever e compreender os padrões de biodiversidade. O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.

Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment’s functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats. patterns BIOTAFAPESP BIOTA FAPESP Brazil BIOTAAraçá Paulo beaches mangroves shores flat services Unfortunately socialenvironmental social economic i.e., ie i e (i.e. vs smallscale small scale biodiversity. . biodiversity) area s functioning macrofauna meiofauna listed information distribution 82 70 225 (22 spp., spp spp. , spp.) 194 (19 177 (17 spp.. 1 threatened exploited Furthermore threats i.e. (i.e 8 7 22 (2 19 (1 17 i.e 2 (

RESUMO O Brasil está entre os maiores produtores mundiais de goiaba (Psidium guajava), mas o rendimento econômico dessa cultura pode ser negativamente afetado pelos danos causados por Ceratitis capitata (Diptera: Tephritidae). Os principais métodos de controle de C. capitata são baseados em aplicações de inseticidas de amplo espectro. Porém, os efeitos negativos do uso desse controle estimulam o desenvolvimento de alternativas sustentáveis, como o uso de óleos essenciais. Nesse sentido, o presente estudo teve como objetivo avaliar a atividade repelente dos óleos essenciais de citronela (Cymbopogon nardus), cravo (Syzygium aromaticum) e copaíba (Copaifera officinalis) em fruto de goiabeiras Paluma contra C. capitata e determinar suas influências na qualidade pós-colheita desses frutos trabalhados. Em condições controladas de laboratório, os frutos foram tratados com óleos essenciais de citronela, cravo e copaíba e acondicionados em recipientes de plástico com dimensões de 20 cm de diâmetro e 15 cm de altura. A análise físico-química dos frutos foi realizada com base nos mesmos óleos aplicados no teste de repelência. O óleo essencial de C. nardus apresentou maior repelência às fêmeas de C. capitata.

ABSTRACT Brazil is one of the world's largest guava (Psidium guajava) producing countries, but the economic performance of this crop can be negatively affected by the damage caused by Ceratitis capitata (Diptera: Tephritidae). The main methods for controlling C. capitata are based on broad-spectrum insecticide applications. However, the negative effects of using this control method stimulate the development of sustainable alternatives, such as the use of essential oils (EO). In this sense, the objective of the present study was to evaluate the repellent activity of EO of citronella (Cymbopogon nardus), clove (Syzygium aromaticum), and copaiba (Copaifera officinalis) for repellency of C. capitata in Paluma guava fruits and determine their effects on postharvest fruit quality, under laboratory-controlled conditions. The fruits were treated with citronella, clove, and copaiba EO and placed in covered plastic containers attached to the ends of arenas of 20 cm diameter and 15 cm height. The fruit physical and chemical analysis was carried out based on the same oils applied in the repellent test. The C. nardus essential oil presented a greater repellency of C. capitata females. The EO applications proved to be a good strategy for maintaining the fruit post-harvest quality. worlds world s Psidium guajava countries Diptera (Diptera Tephritidae. Tephritidae .

Abstract The purpose of this paper was to assess the factor structure of the Spanish Burnout Inventory (SBI) in a multi-occupational sample of Colombian workers. On the basis of previous results and the factor structure of the instrument, a four-factor model was hypothesized. The sample consisted of 153 Colombian workers from different occupational sectors. The SBI was applied. This instrument is composed of 20 items distributed in four dimensions: Enthusiasm toward the job (5 items), Psychological exhaustion (4 items), Indolence (6 items), and Guilt (5 items). The psychometric properties were examined by confirmatory factor analysis (CFA) and the reliability was tested by Cronbach's alpha. The items presented adequate statistical and psychometric values, as well as the scales. The model presented an acceptable fit to the data: GFI = .858, RMSEA = .066(051-079), NNFI = .913, CFI = .927. Reliability was adequate for all scales (a = .79 to a = .87). The results indicate that the SBI is an instrument with psychometric validity to assess the burnout in the Colombian cultural context.

Resumen. El objetivo de este estudio fue analizar la validez factorial del modelo psicométrico del Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo (CESQT) en una muestra multiocupacional de trabajadores colombianos. Se hipotetizó un modelo de cuatro factores con base en la estructura factorial del modelo original. Los participantes fueron 153 trabajadores que desempeñan diversos roles en empresas ubicadas en Colombia. Se aplicó el CESQT que se compone de cuatro dimensiones: Ilusión por el trabajo (5 ítems), Desgaste psíquico (4 ítems), Indolencia (6 ítems) y Culpa (5 ítems). Las propiedades psicométricas fueron examinadas mediante Análisis factorial confirmatorio (AFC) y fiabilidad (alfa de Cronbach). Los ítems presentaron valores estadísticos y psicométricos adecuados, así como las escalas. El modelo presentó un ajuste aceptable a los datos: GFI = .858, RMSEA = .066 (.051.079), NNFI = .913, CFI = .927. La consistencia interna fue alta para todas las escalas del instrumento (a = .79 hasta a = .87). Los resultados indican que el CESQT es un instrumento con suficiente validez psicométrica para evaluar el síndrome de quemarse por el trabajo (SQT) en el contexto cultural colombiano.

This study evaluated the chemical composition, antioxidant and anticholinesterase activities, and the toxicity of hydroethanolic extracts of the Parkia platycephala Benth. Hot extraction with 70% hydroethanolic solution was used to obtain crude extracts of the leaf (LE), bark (BE), flower (FE), and seed (SE). Separation and identification of the compounds were performed by liquid chromatography with diode array detection and gas chromatography coupled with mass spectrometry. Antioxidant and anticholinesterase activities were performed by the 2,2-diphenyl-1-picrylhydrazyl (DPPH•) and Ellman methods, respectively, and the preliminary toxicity by the method with Artemia salina. Chromatography analysis indicated naringin, kaempferol, stigmasterol, and β-sitosterol in all extracts. Gallic acid is prominent in the LE and FE, while ferulic acid is abundant in the BE and lupeol and lupeol acetate are prominent in the SE. The BE antioxidant activity (lethal concentration of 50% (IC50) = 14.72 ± 0.13 µg mL-1) is equivalent to the standard rutin (IC50 = 15.85 ± 0.08 µg mL-1). The SE had the best acetylcholinesterase inhibition potential (IC50 = 5.73 ± 0.68 µg mL-1). Aside from the SE, which is not toxic, the other extracts had low (LE, FE) and moderate (BE) toxicity. The extracts of P. platycephala have potential antioxidant and therapeutic uses, especially against Alzheimer’s disease.

ABSTRACT The defects that drying in concrete yards impose on coffee beans and the search for gourmet coffee production have prompted the emergence of new drying technologies. This work verified the technical and economic feasibility of drying coffee with dehumidified air with a refrigerating capacity of 422,908.7 J s-1, compatible with static capacity dryers equal to 75 m3. Considering the sale price of coffee, the cost of electric energy acquisition, the monthly interest rate and maintenance time, expenses that are equivalent to the depreciation of the concrete yard, a central compound rotational design was considered with 28 tests for the feasibility analysis, including the internal rate of return, net present value and the return on investment. The results showed that in the electric drying units, the dried coffee presents fewer broken and defective beans and has higher retention in a No. 17 sieve. With a higher beverage quality and a price 12.11% higher, drying with dehydrated air showed a PBD of 2.27 years and a return of US$ 2.49 million. The optimisation results were 98.98% desirable. It was concluded that it is economically feasible to dry coffee with dehydrated air and without using a concrete yard.

Abstract Oral thrush or candidiasis is a fairly common infectious fungal disease that is mainly caused by species of the genus Candida spp. In this work, we evaluated the antifungal activity of the essential oil of Cymbopogon citratus (DC) Stapf (lemongrass) and its combination with nystatin against oral cavity yeasts. The oil was extracted by the steam distillation method, and its constituents were quantified. The yeasts were identified using MALDI-TOF MS. The sensitivity to the essential oil and its association with nystatin was verified by the minimum inhibitory concentration (MIC) and checkerboard methods. In the essential oil samples, there were 84.53% of citral. A total of 64.77% of strains were identified as Candida albicans. On susceptibility tests, 83.55% of the yeast isolates were inhibited in concentrations of ≥16 µg/mL of nystatin. C. citratus’s oil was capable of inhibiting and killing all the isolates tested with concentrations that varied from 0.137 to 2.2 mg/mL. The association of oil and nystatin had an additive effect on more than 78% of the strains. The association of this herbal drug with nystatin potentialized the antifungal effect on yeast samples isolated from the oral cavity of oncologic patients.

ABSTRACT Castor bean (Ricinus communis L.) is an oleaginous plant of economic importance due to its different industrial applications. Edaphic characteristics are used to determine the viability of places considered as suitable to obtain castor oil. The objectives of this study were to determine the edaphic characteristics and oil content of R. communis, and to evaluate elicitation with salicylic acid (SA) in El Marqués, Querétaro, Mexico. Sampling was carried out in a direct way, selecting sites where castor bean plants were found. Samples of 1.5 kg of soil were taken and 3 clusters of castor bean in a mature state were collected from 21 accessions. The physicochemical characteristics of the soil and oil content of seeds were determined. Finally, 300 plants of the Guanajuatoil variety were planted and elicitated with different SA concentrations under greenhouse conditions in order to determine oil content. The physical analysis of the soil samples indicated dark-colored soils, Mollisol and Vertisol types, with different textures: clay, clay loam, sandy clay loam and sandy loam. Soil chemical analyses showed the following soil characteristics: pH 7.22; electrical conductivity 0.52 dS m-1; organic matter 7.17%; cation exchange capacity 26.77; calcium 38.62, magnesium 6.81, sodium 13.41and potassium 6.97 cmol kg-1; and nitrogen and phosphorus contents of 16.32 and 54 mg kg-1, respectively. Castor oil content was higher in clay soils (41.46%). The plants elicited with SA presented oil contents ranging from 28.99% to 52.9%, obtained with 100 and 900 ^M. In conclusion, elicitation with SA is an adequate method to increase oil content in castor bean seeds. The locality of El Marqués has good potential for the production of castor oil.
