RESUMO O trabalho teve como objetivo estudar o néctar em flores masculinas e femininas de acessos de abóbora (Cucurbita moschata Duch), visando avaliar o potencial da espécie como planta melífera. Foram realizados dois experimentos, no campo experimental da Universidade do Estado da Bahia, no Departamento de Tecnologia e Ciências Sociais, em Juazeiro-BA, no período de janeiro a dezembro de 2017. Foram avaliados volume, sólidos solúveis e pH do néctar em 32 acessos e no híbrido Tetsukabuto, como testemunha, nos dois tipos florais. Em uma amostra de acessos, foram estudados os tipos de açúcares presentes no néctar. As flores masculinas não apresentaram diferença significativa para as características do néctar, porém, as flores femininas, no primeiro experimento, e os dois tipos florais no segundo experimento apresentaram variação significativa. Nas flores masculinas dos dois experimentos, o máximo de volume de néctar foi de 310 μL e nas femininas foi de 803 μL. A concentração de açúcar ficou ao redor de 24 °Brix. A sacarose se mostrou semelhante nos dois tipos florais e foi superior ao conteúdo de glicose e de frutose, apresentando valores médios de 1.306,13, 357,14 e 351,88 g.mL−1, respectivamente. A obtenção de progênies com caracteres contrastantes dos acessos será importante para o melhoramento da espécie. Esses resultados indicam que a abóbora pode ser considerada como uma planta com um grande potencial melífero.

ABSTRACT The aim of this paper was to study nectar in male and female flowers of pumpkin (Cucurbita moschata Duch) accessions, aiming at evaluating the species potential as a melliferous plant. Two experiments were conducted in an experimental area of the State University of Bahia, at the Department of Technology and Social Sciences, in Juazeiro-BA, in the period from January to December 2017. Nectar volume, soluble solids, and pH were evaluated in the two floral types using 32 accessions and Tetsukabuto hybrid, which was used as check. Using a sample of accessions, the types of sugar present in the nectar were studied. Male flowers did not have significant differences in nectar traits; however, there was significant variation in female flowers in the first experiment and in both floral types in the second experiment. In male flowers in both experiments, the maximum volume of nectar was 310 μL and in female flowers it was 803 μL. The sugar concentration was around 24 °Brix. Sucrose was similar in both floral types and was higher than glucose and fructose contents, showing mean values of 1,306.13, 357.14 and 351.88 g.mL−1, respectively. Obtaining progeny with contrasting characters in the accessions will be important for species improvement. These results indicate that pumpkin might be considered as a melliferous plant with great potential.

ABSTRACT. The aim of this study was to evaluate the inclusion of 50% broken rice (BR) in diets for meat quail from 1 to 35 days old, starting at different ages. A total of 875 mixed quail were allocated to five treatments in a completely randomized design with five replicates of 35 birds. The treatments consisted of a maize- and soybean meal-based control diet and four other similar diets in which the inclusion of 50% BR was started at different ages, namely, 1st, 8th, 15th and 22nd days. Feed intake, weight gain, feed conversion and mortality rate were evaluated weekly. At 35 days, 10 quail per plot were weighed and selected to be slaughtered for evaluations of live weight, carcass yield and gizzard yield. Lastly, a study of economic viability was carried out. No significant difference (p > 0.05) was detected for the performance parameters, live weight or carcass yield, but a higher gizzard yield was found (p < 0.05) in the treatment without BR. The inclusion of BR from the first day of life provided better economic viability. Diets with a maximum inclusion of 50% BR can be formulated for meat quail at any age.

OBJECTIVE: Evaluate the cognitive function and its relationship with balance, history of falls, and fear of falling in the elderly. METHODS: We evaluated 250 elderly persons aged at least 60 years, who answered a sociodemographic questionnaire about the occurrence of falls in the last year. The cognitive function, balance, and fear of falling were assessed using the Mini-Mental State Examination (MMSE), Berg Balance Scale (BBS), and Falls Efficacy Scale (FES-I) scores, respectively. Participants were allocated into two groups based on the Mini-Mental State Examination (MMSE) score, the Group with Possible Cognitive Decline (GPCD) and the group with no cognitive decline (GNCD). We performed Student's t-test and Pearson’s correlation for independent samples. RESULTS: The Group with Possible Cognitive Decline (GPCD) showed lower balance (p=0.003) and greater fear of falling (p=0.008) (BBS=50.98±4.68; FES-I=26.06±8.78) compared to the GNCD (BBS=52.53±3.047; FES-I=23.21±7.74). CONCLUSION: Elderly persons with cognitive decline have lower balance, greater fear of falling, and greater recurrence of falls.

ABSTRACT Objective: to estimate the prevalence of potential drug interactions (PDIs) related to the high-surveillance drugs (HSD) used by a sample of patients admitted to an intensive care unit (ICU). Methods: a cross-sectional, retrospective study with a quantitative approach. Research was based on the analysis of patients prescriptions admitted to the ICU over a one-year period (2014-2015) to identify potential drug interactions related to recurrent HSDs. For each medical record, they were analyzed from the first three to five prescriptions, depending on their availability and the period of individual hospitalization. PDIs identification was made by consulting the Trissels device from the Micromedex 2.0 database. Results: in the 244 drug prescriptions, 846 HSD-related PDIs and 112 different pairs of PDI involving the HSDs were identified. The main HSDs in PDI were: regular insulin, midazolam, fentanyl and tramadol. Of the 112 types of identified PDI, some were recurrent; namely: tramadol and ondansetron, fentanyl and midazolam, midazolam and omeprazole, regular insulin and hydrocortisone, as well as regular insulin and norepinephrine. HSD with PDIs prevalence in this sample was 0.96 (96%). Conclusion: most patients were exposed to PDI involving midazolam, fentanyl or regular insulin. Some vigilance should be established to avoid unnecessary interactions. Alternatively, when the joint administration of certain interactants is indispensable skills should be in place to manage this administration more appropriately and with the lowest possible risk to the patient.

RESUMEN Objetivo: estimar la prevalencia de posibles interacciones farmacológicas (IMP) relacionadas con los medicamentos controlados (MAV) utilizados por una muestra de pacientes ingresados en una unidad de cuidados intensivos (UCI). Métodos: estudio retrospectivo transversal de enfoque cuantitativo. La investigación se basó en el análisis de las prescripciones de los pacientes ingresados en la UCI por un período de un año (2014-2015) para identificar posibles interacciones farmacológicas relacionadas con los MAV recurrentes. Para cada registro médico, se analizaron las primeras tres a cinco recetas, según su disponibilidad y el período de hospitalización del individuo. La identificación de las IMP se realizó consultando el dispositivo Trissels de la base de datos Micromedex 2.0. Resultados: en las 244 recetas de medicamentos, se identificaron 846 IMP relacionadas con MAV y 112 pares diferentes de IMP que involucran MAV. Los principales MAV en las IMP fueron: insulina regular, midazolam, fentanilo y tramadol. De los 112 pares de IMP identificadas, algunas fueron recurrentes; a saber: tramadol y ondansetrón, fentanilo y midazolam, midazolam y omeprazol, insulina regular e hidrocortisona, así como insulina regular y noradrenalina. La prevalencia de las IMP con MAV en esta muestra fue de 0,96 (96%). Conclusión: la mayoría de los pacientes estuvo expuesta a IMP que involucran midazolam, fentanilo o insulina regular. Se debe establecer cierta vigilancia para evitar interacciones innecesarias o cuando la administración conjunta de ciertos interagentes sea indispensable. Debe haber competencia suficiente para manejar la administración de drogas de manera más apropiada, con el menor riesgo posible para el paciente.

Abstract: The aim of the research was to evaluate the effect of the attack Leptocybe invasa in dendrometric variables and wood properties of two clones of eucalyptus (Eucalyptus urophylla and Eucalyptus tereticornis), grown in the municipalities of Imperatriz (state of Maranhão) and Darcinopolis (state of Tocantins), Brazil, for Kraft pulping. Data were collected 10 trees for each clone, the 3-year-old attacked by L. invasa. The diagnosed was based on formation of large guts all over the glass, and emergency hole (closing the loop). The results were confirmed by the variation of the characteristics of species assessed relative to their total height, diameter, volume of bark, vessel frequency, fiber size, radial density profile vessel frequency, fiber size, radial density profile, and ash content. Host trees obtained alterations in dendrometric variables, content of pentosans and wood ashes for both genetic materials, not being observed variations in specific gravity, and size of vessels and fibers, as well as the contents of lignin and wood extractives.

Resumen: El objetivo de la investigación fue evaluar el efecto del ataque de Leptocybe invasa en las propiedades dendrométricas de la madera de dos clones de eucalipto (Eucalyptus urophylla y Eucalyptus tereticornis), cultivados en los municipios de Imperatriz (Estado do Maranhão) y Darcinópolis (Estado de Tocantins), Brasil, destinados a la producción de pulpa kraft. Se analizaron 10 árboles de 3 años de edad atacados por Leptocybe invasa, para cada clon. El diagnóstico fue basado en la formación de grandes agallas en la copa, y con orificio de emergencia (cerrando el ciclo). Los resultados fueron constatados por la variación de las características de las especies evaluadas con relación a su altura total, diámetro, volumen de corteza, frecuencia de vasos, longitud de fibras, perfil radial de densidad y contenido de cenizas. Los árboles hospederos presentaron alteraciones en las variables dendrométricas, contenido de pentosanos y cenizas en la madera para ambos materiales genéticos, no siendo observadas variaciones en la densidad básica, dimensión de vasos y fibras, así como en los contenidos de lignina y extractivos de la madera.

ABSTRACT The productive sustainability of eucalyptus planting is threatened when both diseases and disorders of growth occur. These interferences can have abiotic origin as environmental conditions can negatively affect the wood quality. This study has the goal of evaluating influence of different levels of physiological disorders in dendrometric variables and wood quality from seven-year-old Eucalyptus grandis x Eucalyptus urophylla hybrids intended for wood pulping production. The trees from commercial plantations in State of Maranhão, Brazil were separated into three levels of physiological disorders by means of morphologic changes. Then, they were evaluated according to dendrometric variables, anatomical characteristics, chemical properties, density of wood, and kraft pulp process. The physiological disorder levels significantly influenced all evaluated properties. Moreover, the wood from trees with higher severity of symptoms resulted in higher average values of dendrometric variables, basic density, and fibers dimensions. In addition, apparent density exhibited a different standard in the pith region with increase on radial wood profile. Trees with the least severe disorders exhibited changes in dendrometric and anatomical variables, mainly in wood volume and fibers dimensions, respectively.

BACKGROUND Infection with Zika virus (ZIKV) manifests in a broad spectrum of disease ranging from mild illness to severe neurological complications and little is known about Zika immunopathogenesis. OBJECTIVES To define the immunologic biomarkers that correlate with acute ZIKV infection. METHODS We characterized the levels of circulating cytokines, chemokines, and growth factors in 54 infected patients of both genders at five different time points after symptom onset using microbeads multiplex immunoassay; comparison to 100 age-matched controls was performed for statistical analysis and data mining. FINDINGS ZIKV-infected patients present a striking systemic inflammatory response with high levels of pro-inflammatory mediators. Despite the strong inflammatory pattern, IL-1Ra and IL-4 are also induced during the acute infection. Interestingly, the inflammatory cytokines IL-1β, IL-13, IL-17, TNF-α, and IFN-γ; chemokines CXCL8, CCL2, CCL5; and the growth factor G-CSF, displayed a bimodal distribution accompanying viremia. While this is the first manuscript to document bimodal distributions of viremia in ZIKV infection, this has been documented in other viral infections, with a primary viremia peak during mild systemic disease and a secondary peak associated with distribution of the virus to organs and tissues. MAIN CONCLUSIONS Biomarker network analysis demonstrated distinct dynamics in concurrence with the bimodal viremia profiles at different time points during ZIKV infection. Such a robust cytokine and chemokine response has been associated with blood-brain barrier permeability and neuroinvasiveness in other flaviviral infections. High-dimensional data analysis further identified CXCL10, a chemokine involved in foetal neuron apoptosis and Guillain-Barré syndrome, as the most promising biomarker of acute ZIKV infection for potential clinical application.

The remediation of contaminated soils is probably one of the biggest environmental challenges, mainly due to the complex dynamics of the pollutants in this medium. Among a variety of treatment alternatives proposed for the in-situ remediation of contaminated soils, Fenton processes appear as the most cost-effective, particularly when catalyzed by native iron oxides. However, both the efficiency of the Fenton process and its effect on the treated soil, are largely dependent of the treatment conditions and the main characteristics of the soil, which implies the nonexistence of universal procedures. In this work, the use of Fenton processes in soil remediation routines is critically evaluated, emphasizing aspects related to the degradation efficiency, the influence of the soil properties, the degradation mechanisms and the impacts on the treated soil.

O objetivo deste estudo foi verificar a influência da dupla tarefa no equilíbrio postural de adultos jovens. Fizeram parte do estudo 20 universitários (10 homens e 10 mulheres) com idade média de 25 anos. O equilíbrio postural foi avaliado pelo Sensory Organization Test (SOT), utilizando o Smart Equitest(tm) da NeuroCom(r) International, que avalia a habilidade do indivíduo para usar os diferentes sistemas do controle postural (somatossensorial, vestibular e visual) para se manter em equilíbrio nas 6 condições de conflito sensorial apresentadas pelo sistema. Os sujeitos foram avaliados em tarefa única (manutenção do equilíbrio) e dupla tarefa (manutenção do equilíbrio em conjunto com tarefa cognitiva de cálculo mental), de modo randomizado. O equilíbrio foi mensurado através do escore de equilíbrio, comparando diferenças angulares entre os deslocamentos anterior e posterior máximos. Foi utilizado o teste de Wilcoxon com nível de significância p(0,05 para comparar as médias dos escores de equilíbrio entre a situação sem e com dupla tarefa. Os escores de equilíbrio nas condições do SOT evidenciaram diferença estatisticamente significativa na condição 1 (olhos abertos, plataforma e entorno visual fixos; p=0,018) e na condição 6 (olhos abertos, plataforma oscila e entorno visual fixo; p=0,008), com redução do equilíbrio com a dupla tarefa em ambas. Os resultados mostraram que durante a dupla tarefa, composta pelas quatro operações aritméticas, o controle postural é influenciado negativamente com maior oscilação dos sujeitos. Assim, a complexidade da tarefa secundária pode ter sido o principal motivo para os menores escores de equilíbrio encontrados.

The aim of this study was to investigate the influence of dual-tasking on postural balance in young adults. Participants were 20 college students (10 men and 10 women) with a mean age of 25 years. Postural balance was evaluated by the Sensory Organization Test (SOT), using the Smart Equitest(tm) NeuroCom(r) International, which evaluates the individual's ability to use the different systems of postural control (somatosensory, vestibular and visual) to keep in balance in the 6 conditions of sensory conflict presented by the system. The subjects were evaluated while single-tasking (maintaining balance) and dual-tasking (maintaining balance in conjunction with cognitive mental calculation task) in randomized order. Balance was measured by using the balance score, comparing the angular differences between the maximum anterior and posterior displacements. The Wilcoxon test with significance level of p(0.05 was used to compare the mean scores of balance between the situation with and without dual task. The balance scores in SOT conditions were analyzed and demonstrated statistically significant differences in condition 1 (eyes open, fixed platform and visual surroundings; p=0.018) and condition 6 (eyes open, platform swings and fixed visual surroundings; p=0.008), with reduced balance when dual-tasking in both conditions. The results showed that while performing dual tasks, consisted of four arithmetic operations, the posture control is negatively affected, resulting in a greater oscillation of the subjects. Thus, the complexity of the secondary task may have been the main reason for the lower balance scores found.

Este artículo tuvo por objetivo verificar la influencia de doble tarea en el equilibrio postural de adultos jóvenes. Se han hecho parte del estudio 20 universitarios (10 hombres y 10 mujeres) con promedio de edad de 25 años. El equilibrio postural se evaluó por el Sensory Organization Test (SOT), con uso del Smart Equitest(tm) de la NeuroCom(r) International, el que evalúa la habilidad del sujeto en el uso de los distintos sistemas de control postural (somatosensorial, vestibular y visual) con el fin de mantenerse en equilibrio en las 6 condiciones de conflicto sensorial presentadas por el sistema. Se han evaluados los sujetos en una sola tarea (manutención del equilibrio) y de doble tarea (manutención del equilibrio en relación con la tarea cognitiva de cálculo mental), del modo aleatorizado. Se midió el equilibrio a través de la puntuación de equilibrio, al comparar diferencias angulares entre el desplazamiento anterior y posterior máximos. Se ha hecho la prueba de Wilcoxon con el nivel de significancia p(0,05 para comparar las medias de las puntuaciones de equilibrio entre la situación sin o con doble tarea. Las puntuaciones de equilibrio en las condiciones del SOT han mostrado diferencias estadísticas significativas en la Condición 1 (ojos abiertos, plataforma y entorno visual fijos; p=0,018) y en la Condición 6 (ojos abiertos, plataforma que oscila y entorno visual fijo; p=0,008), con la reducción de equilibrio con doble tarea en ambas las condiciones. Los resultados mostraron que durante la doble tarea, que consiste en las cuatro operaciones aritméticas, el control se influyó negativamente con mayor oscilación de los sujetos. De esa manera, la complejidad de la tarea secundaria puede ser la principal razón para las menores puntuaciones de equilibrio encontradas.
