The present work reports the in situ fabrication of Ag nanoparticles (AgNPs) in polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) over pre-patterned hydrophobic stripes on a hydrophilic glass surface. Microcontact printing (μCP) using octadecyltrichlorosilane (OTS) as “ink” was used to obtain these chemically modified substrates. A comparison of the results of the PS-b-P2VP self-assembly over a bare glass substrate and a pre-patterned glass substrate demonstrated the influence of the pattern on the film morphology. Polymeric films of Ag+ and PS-b-P2VP were prepared on a pre-patterned substrate and heated at 150 °C to enable the self-reconstruction of the polymeric matrix and the in situ formation of AgNPs (average particle size of approximately 100 nm). The AgNP/PS-b-P2VP thin films were characterized using UV-Vis spectroscopy and atomic force microscopy. The results demonstrate that the concentration of the solutions of Ag+/PS-b-P2VP used to prepare the films strongly influences the morphologies and dispersion of AgNPs. Moreover, the surface-enhanced Raman spectroscopy (SERS) activity of the fabricated polymer nanocomposites using Nile Blue as a molecular probe shows the importance of the chemical modification of the substrate in the enhancement of the SERS signal.

Resumé Le télétravail à domicile a atteint 11% de la population occupée du pays dans le contexte de la pandémie de COVID-19. Il s'agissait en majorité de femmes, de personnes blanches, diplômées de l'enseignement supérieur, et travaillant dans les secteurs des services et de la communication. La réalité des télétravailleurs à domicile est différente de celle de la plupart des travailleurs à domicile d'avant la pandémie: femmes noires, peu scolarisées et travaillant dans l'industrie manufacturière. Cependant, en examinant les données du PNAD entre 1992 et 2019, on peut observer la croissance, dans ce type de travail, de la participation des hommes ayant une formation et une rémunération supérieures et travaillant dans les secteurs des services et de la communication. En ce sens, bien que le travail à domicile ait peu varié dans le période, certaines tendances d'évolution de ce type de travail se dégagent des données, réalisées à domicile et sur le profil du travailleur à domicile. Nous comprenons que ces changements observés dans la pré pandémie contribuent à comprendre l'espace que le télétravail à domicile a gagné dans la pandémie, à se renforcer comme modalité de travail et à se justifier comme alternative pour organiser l'espace de travail. 11 COVID19.

Resumo O trabalho remoto atingiu 11% da população ocupada do Brasil no contexto da pandemia da COVID-19: uma maioria de mulheres, pessoas brancas, com nível superior de escolaridade, e atuantes no setor de educação e serviços. Esse perfil é distinto do padrão predominante de trabalhadores em domicílio: mulheres negras com baixo nível de escolaridade e atuantes na indústria de transformação. Mas, ao revisar os dados da PNAD entre 1992 e 2019, encontramos algumas transformações nos setores da economia e atividades ocupacionais realizados em domicílio, bem como uma mudança no perfil do trabalhador em domicílio: crescimento na participação de homens com maior nível de escolaridade e remuneração e atuantes no setor de serviços e de comunicação. Defendemos, neste artigo, que essas mudanças no trabalho em domicílio observadas na pré-pandemia contribuem para compreender o espaço que o trabalho remoto ganhou durante e após a pandemia para se fortalecer enquanto modalidade de trabalho e se justificar enquanto alternativa de organização de espaço de trabalho. 11 COVID19 COVID 19 COVID-19 brancas transformação Mas 199 2019 comunicação Defendemos artigo prépandemia pré 1 COVID1 COVID-1 201 COVID- 20 2

Abstract Remote work reached 11% of Brazil's employed population in the context of the COVID-19 pandemic: the majority being women, white individuals with higher education levels, and working in the education and services sectors. This profile is distinct from the predominant pattern of home-based workers: black women with lower education levels and working in the manufacturing industry. However, upon reviewing PNAD data from 1992 to 2019, we found some transformations in home-based economic sectors and occupational activities. Additionally, there has been a shift in the profile of home-based workers: an increase in the participation of men with higher education and income levels, working in the services and communication sectors. In this article, we argue that these pre-pandemic changes in home-based work contribute to understanding the space that remote work has gained during and after the pandemic to strengthen itself as a work modality and justify itself as an alternative for organizing workspaces. 11 Brazils Brazil s COVID19 COVID 19 COVID-1 homebased home based workers industry However 199 2019 activities Additionally article prepandemic pre workspaces 1 COVID1 COVID- 201 20 2

Abstract Introduction: The pelagic sea snake Hydrophis platurus has the broadest distributional range of all the snakes and is the only sea snake of tropical waters off the west coast of the Americas. Within the variation in the color pattern of this species, completely yellow specimens were considered very rare or occasional. However, a yellow pattern dominates a population established in the interior of the Golfo Dulce in the Southern Pacific of Costa Rica. Objective: We studied the abundance, activity patterns, morphometry, and feeding behavior of the yellow H. platurus within the Golfo Dulce. Methods: Between February 2009 and July 2018, we conducted surveys for sea snakes from a boat within the perimeter of the Golfo Dulce. Results: Adults from the gulf population are smaller than the bicolor oceanic population, with females having larger bodies. Sea snakes within the gulf float and move with surface currents without being linked to drift lines and debris. These snakes are mainly found in clean, calm waters with little turbulence. They feed on a wide diversity of small fish, which they capture using passive stalking predatory behaviors floating on the surface. Prey are quickly captured and swallowed alive. This species has an almost total absence of predation, a pattern that extends to this yellow population. Conclusions: The characteristics of the gulf and the direction and strength of the surface currents at its entrance might restrict the transit of this yellow population to the outside and the entry of the bicolored snakes of the oceanic population. We do not consider making taxonomic changes in this Golfo Dulce population prudent. This yellow population is relatively common within the basin. However, the high tourist traffic and other activities are risk factors for its conservation. Protection policies must be created to preserve and protect this small population of yellow sea snakes unique within this species’ distribution range.

Resumen Introducción: La serpiente marina pelágica Hydrophis platurus tiene el rango de distribución más amplio de todas las serpientes y es la única serpiente marina de aguas tropicales del oeste de América. Dentro de la variación en el patrón de color de esta especie, los ejemplares completamente amarillos se consideraban muy raros u ocasionales. Sin embargo, los patrones amarillos dominan una población establecida en el interior del Golfo Dulce en el Pacífico sur de Costa Rica. Objetivo: Monitoreamos y estudiamos la abundancia, patrones de actividad, morfometría y comportamiento alimentario del H. platurus amarillo dentro del Golfo Dulce. Métodos: Entre febrero 2009 y julio 2018, realizamos búsquedas mensuales de serpientes marinas desde una embarcación dentro del perímetro del Golfo Dulce. Resultados: Los adultos de la población de golfo son más pequeños que la población oceánica bicolor, con las hembras de cuerpos más grandes. Las serpientes del Golfo Dulce flotan y se mueven con las corrientes superficiales sin asociarse con líneas de deriva y escombros. Las serpientes se encuentran principalmente en aguas limpias y tranquilas con poca turbulencia. La dieta se compone de una amplia diversidad de peces pequeños, que capturan con un comportamiento depredador de acecho pasivo, flotando en la superficie. La presa es rápidamente capturada y tragada viva. Esta especie tiene una ausencia casi total de depredación, patrón que se extiende a esta población amarilla. Conclusiones: Las características del golfo y la dirección y fuerza de las corrientes superficiales en su entrada podrían restringir el tránsito de esta población amarilla hacia el exterior y el ingreso de las serpientes bicolores de la población oceánica. No consideramos prudente realizar cambios taxonómicos en esta población. La población amarilla es relativamente abundante dentro de la cuenca. Sin embargo, el alto tráfico turístico y otras actividades son factores de riesgo para su conservación. Políticas de protección deben crearse para preservar y proteger esta pequeña población de serpientes marinas amarillas, única dentro del rango de distribución de esta especie.

Abstract Introduction: Extensive cattle ranching in tropical dry forest areas (TDF) has caused the transformation of natural ecosystems and has altered the behavior of associated organisms, generating variation in activity patterns. In bats, the activity pattern is affected by the composition and vegetation structure of the ecosystem, and by the climatic season (dry and rainy). Therefore, it is expected that conventional extensive livestock systems, as opposed to silvopastoral systems where environmental heterogeneity is favored, determine the activity of bats. Objective: To compare the activity patterns of bats in conventional management systems (CS) and silvopastoral (SPS) of extensive cattle ranching associated with TDF in the Colombian Caribbean. Methods: The activity pattern of bats in TDF fragments associated with conventional and silvopastoral systems was compared within an annual cycle. The daily activity patterns of 11 species with records for over 10 days in both livestock management systems were determined. Results: A total of 2 788 bats were captured, from six families, 22 genera, and 37 species. Greater bat activity was recorded during the rainy season. We found that although bats show behavioral adaptation to the different management systems (except for Carollia perspicillata, Dermanura phaeotis and Glossophaga soricina), in TDF fragments associated with SPS there is greater bat activity throughout the year, compared to the activity recorded in CS. Likewise, the only nectarivorous species evaluated, G. soricina, also presented the lowest overlap value between the two types of management SC and SSP. Conclusion: The TDF fragments associated with SPS, due to the vegetation composition and structure, probably favor the constant supply of resources suitable for the bats’ assemblage stability, especially flowers and fruits.

Resumen Introducción: La ganadería extensiva en áreas de bosque seco tropical (bs-T) ha causado la transformación de los ecosistemas naturales, y ha alterado la conducta de los organismos asociados, generando variación en los patrones de actividad. En murciélagos, el patrón conductual se ve afectado por la composición y estructura vegetal del ecosistema, y por la época climática (seca y lluviosa). Por lo que, se espera que en los sistemas convencionales de ganadería extensiva a diferencia de los silvopastoriles donde se favorece la heterogeneidad ambiental, determine la actividad de los murciélagos. Objetivo: Comparar los patrones de actividad de los murciélagos en sistemas de manejo convencional (SC) y silvopastoril (SSP) de ganadería extensiva asociados al bs-T en el Caribe colombiano. Métodos: Se comparó el patrón de actividad de los murciélagos en fragmentos de bs-T asociados a SC y SSP durante un ciclo anual. Se determinó el patrón de actividad diaria de 11 especies con registros mayores a 10 días en ambos sistemas de manejo de ganadería. Resultados: Un total de 2788 murciélagos fueron capturados, de seis familias, 22 géneros y 37 especies. Se registró mayor actividad de murciélagos durante la época de lluvias. Encontramos que a pesar de que los murciélagos presentan adaptación del comportamiento a los diferentes sistemas de manejo (excepto Carollia perspicillata, Dermanura phaeotis y Glossophaga soricina), en fragmentos de bs-T asociados a SSP se presenta mayor actividad de los murciélagos durante todo el año, con respecto a la actividad registrada en los SC. Igualmente, la única especie nectarívora evaluada, G. soricina, presentó también el menor valor de solapamiento entre los dos tipos de manejo SC y SSP. Conclusión: Los fragmentos de bs-T inmersos en SSP debido a la estructura del paisaje, podrían estar favoreciendo la oferta constante de recursos adecuados para la estabilidad del ensamblaje de murciélagos, en especial flores y frutos.

SUMMARY: The study was designed to explore the association between the immunolocalization of alpha-smooth muscle actin (α- SMA) and S100 proteins within the efferent ductules (ED) from one side, and the sexual maturity and seasonality from the other side. For each season, tissue specimens were obtained from 7 adult and 7 juvenile, clinically healthy male dromedaries. Specimens were investigated by the standard immunohistochemical procedures. The immunohistochemical findings displayed that the pattern of expression was similar for both proteins, either in adults or in juveniles. Expression was significantly higher in adults during season of sexual activity (winter), fairly reduced during periods of transition from activity to inactivity (spring) or from inactivity to activity (autumn) and reaches its lowest magnitude during season of sexual inactivity (summer). On the other hand, a moderate immunoreactivity of both proteins in ED from juvenile male camels was nearly uniform throughout the year. The immunoreactivity for both α-SMA (smooth muscle cells in ductular and vascular walls) and S100 (ductular ciliated cells), was evident during periods of sexual activity. It can be concluded that the immunoreactivity is androgen- dependent and positively correlated with both of sexual activity and maturity, suggesting a crucial role of both α-SMA and S100 proteins in the regulation of the diverse functions of the ED in male dromedaries.

RESUMEN: El estudio fue diseñado para explorar la asociación entre la inmunolocalización de la actina de músculo liso alfa (α-SMA) y las proteínas S100 dentro de los conductos eferentes (ED) por una pate, y la madurez sexual y estacionalidad por otra parte. Para cada estación, se obtuvieron muestras de tejido de 7 dromedarios machos adultos jóvenes y clínicamente sanos. Las muestras se investigaron mediante procedimientos inmunohistoquímicos estándar. Los hallazgos inmunohistoquímicos mostraron que el patrón de expresión era similar para ambas proteínas, ya sea en adultos o en jóvenes. La expresión fue significativamente mayor en adultos durante la temporada de actividad sexual (invierno), bastante reducida durante los períodos de transición de actividad a inactividad (primavera) o de inactividad a actividad (otoño) y alcanzaba su magnitud más baja durante la temporada de inactividad sexual (verano). Por otro lado, una inmunorreactividad moderada de ambas proteínas en el DE de camellos machos juveniles fue casi uniforme durante todo el año. La inmunorreactividad tanto para α-SMA (células musculares lisas en las paredes ductulares y vasculares) como para S100 (células ciliadas ductulares), fue evidenciada durante los períodos de actividad sexual. Se puede concluir que la inmunorreactividad es dependiente de los andrógenos y se correlaciona positivamente tanto con la actividad sexual como con la madurez, lo que sugiere un papel crucial de las proteínas α-SMA y S100 en la regulación de las diversas funciones del DE en dromedarios machos.

Abstract Renal involvement is one of the most severe morbidities of Fabry disease (FD), a multisystemic lysosomal storage disease with an X-linked inheritance pattern. It results from pathogenic variants in the GLA gene (Xq22.2), which encodes the production of alpha-galactosidase A (α-Gal), responsible for glycosphingolipid metabolism. Insufficient activity of this lysosomal enzyme generates deposits of unprocessed intermediate substrates, especially globotriaosylceramide (Gb3) and derivatives, triggering cellular injury and subsequently, multiple organ dysfunction, including chronic nephropathy. Kidney injury in FD is classically attributed to Gb3 deposits in renal cells, with podocytes being the main target of the pathological process, in which structural and functional alterations are established early and severely. This configures a typical hereditary metabolic podocytopathy, whose clinical manifestations are proteinuria and progressive renal failure. Although late clinical outcomes and morphological changes are well established in this nephropathy, the molecular mechanisms that trigger and accelerate podocyte injury have not yet been fully elucidated. Podocytes are highly specialized and differentiated cells that cover the outer surface of glomerular capillaries, playing a crucial role in preserving the structure and function of the glomerular filtration barrier. They are frequent targets of injury in many nephropathies. Furthermore, dysfunction and depletion of glomerular podocytes are essential events implicated in the pathogenesis of chronic kidney disease progression. We will review the biology of podocytes and their crucial role in regulating the glomerular filtration barrier, analyzing the main pathogenic pathways involved in podocyte injury, especially related to FD nephropathy.

Resumo O acometimento renal é uma das mais severas morbidades da doença de Fabry (DF), enfermidade multissistêmica de depósito lisossômico com padrão de herança ligada ao cromossomo X, decorrente de variantes patogênicas do gene GLA (Xq22.2), que codifica a produção de alfa-galactosidase A (α-Gal), responsável pelo metabolismo de glicoesfingolipídeos. A atividade insuficiente dessa enzima lisossômica gera depósitos de substratos intermediários não processados, especialmente do globotriaosilceramida (Gb3) e derivados, desencadeando injúria celular e, posteriormente, disfunção de múltiplos órgãos, incluindo a nefropatia crônica. A lesão renal na DF é classicamente atribuída aos depósitos de Gb3 nas células renais, sendo os podócitos o alvo principal do processo patológico, nos quais as alterações estruturais e funcionais são instaladas de forma precoce e severa, configurando uma podocitopatia metabólica hereditária típica, cujas manifestações clínicas são proteinúria e falência renal progressiva. Embora os desfechos clínicos tardios e as alterações morfológicas estejam bem estabelecidos nessa nefropatia, os mecanismos moleculares que deflagram e aceleram a injúria podocitária ainda não estão completamente elucidados. Podócitos são células altamente especializadas e diferenciadas que revestem a superfície externa dos capilares glomerulares, desempenhando papel essencial na preservação da estrutura e função da barreira de filtração glomerular, sendo alvos frequentes de injúria em muitas nefropatias. A disfunção e depleção dos podócitos glomerulares são, além disso, eventos cruciais implicados na patogênese da progressão da doença renal crônica. Revisaremos a biologia dos podócitos e seu papel na regulação da barreira de filtração glomerular, analisando as principais vias patogênicas envolvidas na lesão podocitária, especialmente relacionadas à nefropatia da DF.

Resumen: En la actualidad, existen materiales provenientes de la industria, que bajo ciertas condiciones físicas pueden aportar al mejoramiento de las propiedades de mecánicas de un suelo. Materiales como el polvo de ladrillo (BD) y las cenizas de carbón (FA) tienen contenidos altos de SiO2 y Al3O2, que denotan actividad puzolánica. Además, se ha comprobado que dichos materiales pueden activarse al combinarse con cal. Esto genera procesos internos de cementación cuando el tamaño de grano es de 75 micras. Las vías rurales en Colombia presentan uno de los porcentajes más altos de toda la red vial y solo un 7% aproximadamente se encuentra en buen estado. Las difíciles condiciones de acceso, la susceptibilidad de los suelos, la imposibilidad financiera de intervenir toda esta red y la necesidad de implementar procesos de economía circular hace que estos materiales sean atractivos en temas de estabilización para mejorar las condiciones de tránsito. El BD y FA fueron aplicadas en dosificaciones del 0%, 3%, 6%, 9%, 12% y 24% en suelos finogranulares (limo y arcilla) y suelos arenosos, se evaluó la compactación y se realizó un diseño experimental factorial para evaluar la influencia del material en la variable resistencia a la compresión inconfinada, por medio de un análisis ANOVA. Para evaluar el desempeño del BD y las FA, se realizó una pista de prueba sobre una vía de bajo volumen de tráfico en el norte de Colombia, la cual tenía un suelo arenoso. BD y FA fueron adicionados al 12% y activados con cal, en celdas de 30 m de longitud. Para establecer un patrón comparativo se hicieron otras celdas en las mismas condiciones geométricas con materiales que usualmente se usan en este tipo de aplicaciones como el cemento. Estas celdas fueron evaluadas en periodo de 16 meses. Características como el módulo resiliente, El índice de internacional de rugosidad IRI y el coeficiente de resistencia al deslizamiento fueron medidos en ese período. Los resultados indican que cuando se adicionan estos materiales en suelos finogranulares (limos y arcillas), la resistencia a la compresión inconfinada aumenta un 150% respecto al suelo sin estabilizar, mientras que para suelos arenosos la resistencia aumenta desde un 70% hasta un 125%. Durante el período de evaluación, el BD y las FA lograron presentar aumentos por encima del 50% en el módulo resiliente respecto al suelo sin estabilizar. Sin embargo, las FA presentaron resultados comparables respecto al tramo estabilizado con cemento. Adicionalmente, sin bien, los tramos se fueron deteriorando en el tiempo, mantuvieron su indicen de rugosidad dentro de los rangos admisibles indicativos de buen índice de serviciabilidad.

Abstract: Currently, there are materials from industry that, under certain physical conditions, can contribute to the improvement of soils mechanical properties. Materials such as brick dust (BD) and fly ash (FA) have high SiO2 and Al2O3 contents, which denote pozzolanic activity. In addition, it has been shown that these materials can be activated when combined with lime. This generates internal cementation processes when the particle size is 0.075 mm. Rural roads in Colombia have one of the highest percentages of the entire road infrastructure, and only about 7% are in good condition. Difficult access conditions, soil susceptibility, the financial impossibility of intervening in this entire network and the need to implement circular economy processes, make these materials attractive in terms of stabilization to improve traffic conditions. BD and FA were applied in dosages of 0%, 3%, 6%, 9%, 12% and 24% in finogranular soils (silt and clay) and sandy soils, compaction was evaluated, and a factorial experimental design was carried out to evaluate the influence of the material on the variable unconfined compressive strength (UCS), through an ANOVA analysis. To evaluate the performance of BD and FA, a test track was made on a low traffic volume road in northern Colombia, which had a sandy soil. BD and FA were added at 12% and activated with lime, in 30 m long cells. To establish a comparative pattern, other cells were made in the same geometric conditions with materials that are usually used in this type of application, such as cement. These cells were evaluated over a period of 16 months. Characteristics such as resilient modulus, international roughness index (IRI) and slip resistance coefficient were measured during this period. The results indicate that when these materials are added to finogranular soils (silts and clays), the UCS increases by 150% with respect to the unstabilized soil, while for sandy soils the strength increases from 70% to 125%. During the evaluation period, the BD and the FA were able to increases of over 50% in the resilient modulus with respect to the unstabilized soil. However, the FA showed comparable results with respect to the cement-stabilized cell. In addition, although the sections deteriorated over time, they maintained their roughness index within the admissible ranges indicative of a good serviceability index.

Abstract Introduction The forestry sector faces energy challenges that involve the precise determination of the final energy consumption to achieve improvements. Objective To estimate the final energy consumed while processing timber forest resources. Materials and methods The Total Final Consumption (TFC) was determined in six companies (statistical units) engaged in primary timber processing in Pueblo Nuevo, Durango. Activity data and significant energy uses (SEUs) for two years were obtained through an energy audit. The data were disaggregated by statistical unit, activity, form and application of energy, and expressed in tons of oil equivalent (toe). Results and discussion The energy consumption per statistical unit was estimated at 71.19 toe·yr-1, releasing 260.14 tCO2e·yr-1. SEU was identified in vehicles with diesel engines (75 %). The use of gasoline and electrical energy in machines accounted for 14.2 % and 10.7 %, respectively. Electric motors used up to 98 % of the electrical energy. Logging represented 69 % of the Total Final Consumption (TFC), more than twice compared to sawing. Energy consumption was significantly different between statistical units (Tukey, P < 0.05) for sawing, but not for logging. Conclusions Energy consumption for logging was similar among the units studied but was not similar for sawing. An effective energy management program and the integration of wood energy could optimize the consumption pattern.

Resumen Introducción La actividad forestal enfrenta desafíos energéticos que implican la determinación precisa del uso final de energía para lograr mejoras en su rendimiento. Objetivo Estimar la cantidad de energía de uso final consumida durante el procesamiento de los recursos forestales maderables. Materiales y métodos El consumo final total de energía (CFT) se determinó en seis empresas (unidades estadísticas) de transformación primaria de la madera en Pueblo Nuevo, Durango. Los datos de actividad y los usos significativos de la energía (USEn), correspondientes a dos años, se obtuvieron mediante una auditoría energética. Los datos se desagregaron por unidad estadística, actividad, forma y aplicación de la energía y se expresaron en toneladas equivalentes de petróleo (tep). Resultados y discusión El consumo de energía por unidad estadística se estimó en 71.19 tep·año-1, liberando 260.14 tCO2e·año-1. El USEn se identificó en vehículos con motor de diésel (75 %). El uso de gasolina y energía eléctrica en máquinas correspondió al 14.2 % y 10.7 %, respectivamente. Los motores utilizaron hasta 98 % de la energía eléctrica. La extracción de madera ocupó 69 % del CFT, más del doble que el aserrado de madera. El consumo de energía fue significativamente diferente entre unidades estadísticas (Tukey, P < 0.05) durante el aserrado, pero no en la extracción de madera. Conclusiones El consumo de energía en la actividad de extracción de madera fue similar entre las unidades estudiadas, pero no en la etapa de aserrado. Un programa efectivo de gestión de la energía y la integración de la dendroenergía podría optimizar el modelo de consumo.

RESUMEN En la Amazonía ecuatoriana, cada día son mayores los desafíos para la identificación de especies fitorremediadoras que disminuyan la contaminación por metales pesados producto de la actividad minera. El objetivo de este trabajo fue evaluar el potencial bioacumulador de metales pesados de tres especies forestales de rápido crecimiento (Ochroma pyramidale, Piptocoma discolor y Bambusa vulgaris) en un área de extracción minera, en la comunidad Yutzupino, Napo para la restauración. Se recolectaron muestras de hoja y suelo para determinar la concentración de metales pesados (Cd, Pb, Fe y Ni), mediante espectrometría de absorción atómica y se calculó el factor de bioconcentración (FBC). Los análisis foliares mostraron que B. vulgaris presentó mayor concentración de Ni (6,89 mg kg-1) y Fe (156,33 mg kg-1) y P. discolor contenía Cd (0,35 mg kg-1) y Pb (55,67 mg kg -1). Los análisis de suelos mostraron un patrón de variación en B. vulgaris superior en Cd, Ni y Pb y en O. pyramidale para Fe. El factor de bioconcentración permitió identificar la capacidad acumuladora de las especies, lo que sugiere que P. discolor puede ser utilizada como especie fitorremediadora para sitios contaminadas por Cd y Pb, O. pyramidale para Ni y B. vulgaris para Fe.

RESUMO Na Amazônia equatoriana, os desafios para a identificação de espécies de fitorremediação para reduzir a contaminação por metais pesados provenientes de atividades de mineração aumentam a cada dia. O objetivo deste trabalho foi avaliar o potencial bioacumulativo de metais pesados de três espécies florestais de crescimento rápido (Ochroma pyramidale, Piptocoma discolor e Bambusa vulgaris) em uma área de extração de mineração na comunidade de Yutzupino, Napo, para restauração. Amostras de folhas e de solo foram coletadas para determinar a concentração de metais pesados (Cd, Pb, Fe e Ni) por espectrometria de absorção atômica e o fator de bioconcentração (BCF) foi calculado. A análise das folhas mostrou que a B. vulgaris tinha concentrações mais altas de Ni (6,89 mg kg-1) e Fe (156,33 mg kg-1) e a P. discolor continha Cd (0,35 mg kg-1) e Pb (55,67 mg kg -1). As análises do solo mostraram um padrão de variação em B. vulgaris maior em Cd, Ni e Pb e em O. pyramidale para Fe. O fator de bioconcentração identificou a capacidade de acumulação das espécies, sugerindo que P. discolor pode ser usada como uma espécie de fitorremediação para locais contaminados com Cd e Pb, O. pyramidale para Ni e B. vulgaris para Fe.

ABSTRACT In the Ecuadorian Amazon, the challenges for identifying, phytoremediation species that reduce heavy metal contamination resulting from mining activity are increasing every day. The objective of this work was to evaluate the bioaccumulator potential of heavy metals of three fast-growing forest species (Ochroma pyramidale, Piptocoma discolor and Bambusa vulgaris) in a mining extraction area, in the Yutzupino community, Napo for restoration. Leaf and soil samples were collected to determine the concentration of heavy metals (Cd, Pb, Fe and Ni) using atomic absorption spectrometry and the bioconcentration factor (BCF) was calculated. Leaf analyzes showed that B. vulgaris presented a higher concentration of Ni (6.89 mg kg-1 ) and Fe (156.33 mg kg-1 ) and P. discolor contained Cd (0.35 mg kg-1 ) and Pb (55.67 mg kg -1 ). Soil analyzes showed a pattern of variation in B. vulgaris superior in Cd, Ni and Pb and in O. pyramidale for Fe. The bioconcentration factor allowed identifying the accumulating capacity of the species, which suggests that P. discolor may be used as a phytoremediation species for sites contaminated by Cd and Pb, O. pyramidale for Ni and B. vulgaris for Fe.

Resumen La ingeniería inversa se realiza en múltiples contextos. Cada contexto está definido por un grupo de participantes, un conjunto de recursos y situaciones que se encuentran dentro de un ámbito específico. Existen múltiples propuestas para realizar ingeniería inversa, sin embargo, todas asumen que se hace en el contexto de la producción de software. El objetivo de este trabajo es proponer un referente para recuperar el diseño de productos software, que pueda ser utilizado en diferentes contextos. Se hizo un análisis comparativo de los enfoques de ingeniería inversa utilizando la técnica de coincidencia de patrones. Para validar los resultados obtenidos se realizó un estudio de caso en dos contextos diferentes, el primero en un contexto de educación para apoyar un proceso de enseñanza aprendizaje y el segundo en un contexto de producción para recuperar el diseño de un producto software. Se definió un marco de referencia conformado por un sistema conceptual descriptivo y un conjunto de elementos instrumentales de tipo operativo, que guía el proceso de recuperación del diseño de productos software, ajustándose a las características del contexto en el que se realiza esta actividad. Se concluye que el marco de referencia definido, ofrece un nuevo enfoque para la recuperación del diseño de productos software, porque involucra el contexto en el que se realiza el proceso y oculta su complejidad a los participantes que no son expertos en ingeniería inversa.

Abstract Reverse engineering is applied in multiple contexts. Each context is defined by a group of stakeholders, a set of resources and situations within a specific scope. There are diverse approaches for reverse engineering, however, all they assume that it is done in the context of software production. The aim of this work is to define an approach to recover the design of software products in different contexts. A comparative analysis of reverse engineering approaches was made using the pattern matching technique. To validate obtained results, a case study was carried out in two distinct contexts, the first in an education context to support a teaching-learning process and the second in a software production context to retrieve a software product design. A framework was defined, which includes a descriptive conceptual system and a set of instrumental elements of operational type, which serves to guide the software product design recovery process, based on the context in which this activity is carried out. It is concluded that the defined framework offers a new approach to software design recovery, because it involves the context where the process takes place and hides its complexity from non-expert stakeholders in reverse engineering.

Resumen Introducción: Las malformaciones del desarrollo cortical se deben a alteraciones en la migración del neuroblasto durante la formación de la corteza cerebral. Se desconoce su frecuencia en embarazos monocoriales. Objetivo: Reportar el caso de un embarazo monocorial con diagnóstico de malformación del desarrollo cortical en uno de los fetos y revisar la literatura referente a su diagnóstico y pronóstico. Método: Mujer de 19 años, embarazo monocorial biamniótico de 26 semanas, que acudió con estudio ecográfico y resonancia fetal que evidenció en uno de los fetos asimetría de los hemisferios cerebrales, hipoplasia de la cisura de Silvio izquierda con simplificación del patrón giral por focos de paquigiria y polimicrogiria, con confirmación posnatal de alteración en la migración neuronal asociada a hipoplasia vermiana. Resultados: Se encontraron en la literatura tres casos de embarazo múltiple monocorial con trastorno de la migración neuronal con recién nacidos vivos. Los hallazgos más comunes fueron microcefalia, lisencefalia e hipoplasia cerebelosa. Conclusiones: El diagnóstico prenatal del trastorno de la migración neuronal se realiza con ecografía y resonancia fetal. La más frecuente es la alteración de la migración neuronal tipo II. El pronóstico depende del tipo de alteración; sin embargo, la mayoría de los casos presentan trastornos epileptiformes con alteraciones del neurodesarrollo.

Abstract Introduction: Malformations of cortical development are the result from alterations in the neuroblast migration during the cerebral cortex formation. It’s frequency in monochorial multiple pregnancies remains unknown. Objective: To report a case of monochorial multiple pregnancy with diagnosis of malformation of the cortical development in one of the fetuses. In addition, to review the literature regarding the diagnosis and prognosis of this entity. Method: A 19-year-old female with a monochorial diamniotic pregnancy of 26 weeks’ gestation, arrived with an ultrasound anatomy scan visit, and fetal magnetic resonance imaging, we detected asymmetry in the cerebral hemispheres one of the fetuses, hypoplasia of the left sulcus of Sylvius with simplification of the gyrus pattern due to clusters of pachygyria and polymicrogyria. Those findings were confirmed afterbirth, with a definite diagnosis of neuronal migration disorder associated with vermian hypoplasia. Results: Three cases of monochorial pregnancy with neuronal migration disorder with live newborn, common findings like microcephaly, lissencephaly and vermian hypoplasia. Conclusions: Prenatal diagnosis with neuronal migration disorder is done via ultrasound and magnetic resonance imaging. Neuronal migration disorders type II are the most common of them. Prognosis depends on the type of disorder; however, most patients have epileptiform activity and neurodevelopment impairment.

Resumo: Apresentamos o caso de um paciente de 31 anos de idade que trabalha em um moinho de grãos há 12 anos e desenvolveu asma ocupacional. O objetivo do artigo é apresentar a justificativa da origem ocupacional da asma adquirida. Descrevemos as tarefas realizadas, os materiais e os meios de trabalho utilizados. Analisamos especialmente a exposição ocupacional à poeira orgânica e sua conexão temporal com a sintomatologia respiratória. Essas informações nos permitem entender a importância das condições em que o trabalho é realizado e a exposição a um fator de risco, a poeira orgânica, para o desenvolvimento da patologia respiratória ocupacional. As medições do volume pulmonar expiratório máximo foram realizadas com a técnica de pico de fluxo durante e fora da jornada de trabalho. Observamos variações no fluxo expiratório superiores a 20%, tanto durante quanto fora do horário de trabalho, com um padrão sintomático semelhante ao relatado pelo trabalhador. Concluímos que há evidências de um nexo causal entre asma e trabalho e, portanto, propomos o diagnóstico de asma ocupacional. Destacamos a importância de avaliar os riscos ocupacionais em cada atividade para implementar planos de vigilância da saúde tanto do trabalhador quanto do ambiente de trabalho, a fim de evitar o surgimento e a evolução dessa ou de outras patologias que, em muitos casos, geram incapacidade para a tarefa e deterioração da qualidade de vida dos trabalhadores.

Resumen: Se presenta el caso de un trabajador de 31 años que desempeña tareas en un molino de granos desde hace 12 años y que ha desarrollado asma ocupacional. El objetivo del artículo es presentar los fundamentos utilizados para sostener el origen profesional del asma adquirido. Se describen las tareas laborales que desarrolla, materiales y medios de trabajo que utiliza. Se analiza en particular la exposición laboral a polvo orgánico y su vinculación temporal con la sintomatología respiratoria. Esta información permite comprender la importancia de las condiciones en las que realiza el trabajo y la exposición a un factor de riesgo, el polvo orgánico, para el desarrollo de la patología respiratoria laboral. Se realizaron mediciones de volumen máximo espiratorio pulmonar, con técnica de pico flujo, durante la jornada laboral y fuera de ésta. Se observaron variaciones del flujo espiratorio mayores a 20%, tanto durante la jornada laboral como fuera de ella, con similar patrón sintomático, según relata el trabajador. Se concluyó que existe evidencia del nexo causal entre el asma y el trabajo, por lo que se plantea el diagnóstico de asma ocupacional. Se destaca la importancia de evaluar los riesgos laborales en cada actividad para implementar planes de vigilancia de la salud, tanto del operario como del ambiente de trabajo, para prevenir la aparición como la evolución de esta u otras patologías que en muchos casos generan incapacidad para la tarea y deterioro de la calidad de vida de los trabajadores.

Abstract: We present the case of a 31-year-old worker who has been working in a grain mill for 12 years and has developed work-related asthma. The objective of this article is to present the foundations used to support the occupational origin of the acquired asthma. The study describe the work tasks performed, the materials used, and the working methods. The work-related exposure to organic dust and its temporal relationship with respiratory symptoms is particularly analyzed. This information allows us to understand the importance of working conditions and exposure to organic dust, a risk factor, for the development of this work-related respiratory pathology. Measurements of maximum expiratory lung volume were made using the peak flow technique during and outside of the workday. Expiratory flow variations greater than 20% were observed, both during and outside of the workday, which followed a similar symptomatic pattern as reported by the worker. The study concluded that there is evidence of a causal link between asthma and work, thus suggesting the diagnosis of work-related asthma. The importance of assessing occupational risks in each activity to implement health surveillance plans for both workers and the work environment is highlighted, aiming to prevent the onset and progression of this and other pathologies that often result in work incapacity and deterioration of workers’ quality of life.

Resumo O estudo das serpentes envolve fatores fisiológicos, comportamentais e de interação com um ambiente extremamente dinâmico e complexo. A relação destes animais com a biodiversidade ainda é bastante preliminar, pouco estudada e muito alimentada por práticas populares ligadas a medicina tradicional, correntes esotéricas e místicas. Nessa linha que este estudo propôs conhecer sobre o efeito do extrato bruto alcoólico a 80% da Petiveria alliacea L, popularmente conhecida como Erva Tipi, e seus efeitos associados à repelência da serpente Bothrops moojeni. Foi construído um complexo de caixas para a observação do deslocamento da serpente, realizado por um período total de seis dias, sendo os três primeiros para definição do padrão exploratório e os outros dois para o teste ao extrato alcóolico de Tipi e finalmente no sexto dia um ciclo com presença de um atrativo vivo. Foi observado que o animal não teve comportamento de inibição e se deslocou pelo complexo de forma análoga ao que ocorre na natureza e demonstrou comportamento de evitar se manter na presença do extrato tanto com a presença de um atrativo vivo como sem ele, preferindo se deslocar nos outros compartimentos. Os resultados mostram que essa ferramenta proposta é valida para estudo de deslocamento das serpentes Bothrops moojeni, da mesma maneira que agregou valores na importância da biodiversidade do Cerrado e sobre as práticas populares da Erva Tipi, uma vez que o efeito repelente sobre a serpente foi significativo nos dois testes realizados.

Abstract The serpent study involves physiological, behavioral and interaction factors with an extremely dynamic and complex environment. The relation of these animals with biodiversity is still quite preliminary, little studied and sustained by popular practices related to traditional medicine, esoteric and mystical currents. Therefore, this study proposed to know about the effect of 80% crude alcoholic extract of Petiveria alliacea L., popularly known as Tipi Herb, and its effects associated with the repellency of the Bothrops moojeni serpent. A complex of boxes was built for the observation of the snake's displacement, carried out for a total period of six days, the first three for defining the exploratory pattern and the other two for testing the alcoholic extract of Tipi, and finally on the sixth day, one cycle with the presence of a live attractant as bait. It was observed that the animal had no inhibition behavior and moved through the complex in a way like what occurs in nature and showed behavior to avoid remaining in the presence of the extract both with the presence of a live attractant or without it, preferring to move in the other compartments. The results show that this proposed tool is valid for the study of displacement of Bothrops moojeni snakes, in the same way that it added values on the importance of cerrado biome biodiversity and on the popular medicine practices of Tipi Herb, since the repellent effect on the snake was significant in the two tests performed.

ABSTRACT BACKGROUND: The identification and understanding of dietary factors and other characteristics that influence gestational weight gain can contribute to the formulation of strategies to promote healthy eating habits before and during pregnancy. OBJECTIVE: To investigate the association between dietary patterns, sociodemographic and obstetric characteristics, and health-related behaviors in pregnant women. DESIGN AND SETTING: A cross-sectional study was conducted on women undergoing prenatal care in the Unified Health System of Colombo, Paraná, Brazil, from February 2018 to September 2019. METHOD: A weekly food frequency questionnaire was administered, and dietary patterns were identified through factor analysis. Median regression models were constructed to identify the associations between dietary pattern scores and variables. RESULTS: Complete data were obtained from 495 pregnant women. Three dietary patterns were identified: 1) “healthy,” with higher factor loadings for the weekly consumption of raw vegetables, cooked vegetables, and fresh fruits; 2) “Western,” including soft drinks or artificial juice, candies, milk, and dairy products, and processed cold meat; and 3) “traditional,” beans and meat. Pregnant women aged 30 years or older (coefficient [Coef.] 0.86, 95% confidence interval [CI] 0.38–1.33) with moderate/intense physical activity (Coef. 0.32, 95% CI 0.02–0.62) had higher adherence to the “healthy” pattern. Adolescents and smokers adhered more to the “traditional” pattern (Coef. 0.17, 95% CI 0.01–0.33). CONCLUSION: Age, smoking status, and physical activity were associated with dietary patterns in pregnant women.
