Diaporthe phaseolorum, an endophyte isolated from Combretum lanceolatum, has exhibited diverse biological activities including antimicrobial, leishmanicidal, antitumoral, and herbicidal properties. Regardless of these activities, there remains limited research on its chemical constituents. Therefore, this study aimed to investigate the metabolome of D. phaseolorum employing mass spectrometry data dereplication through molecular networking and MolNetEnhancer tools. Twenty two molecular families were annotated, including prenol lipids, benzenoids, organoheterocyclic compounds, and nucleosides. Among the 41 nodes annotated, 36 metabolites were confirmed via spectral references, including alismol, farnesol, linoleic acid, tyramine, N-acetyl-tyramine, 5-methoxy-1H-indole-3-carbaldehyde, 6-pentyl-2H-pyran-2-one, and adenosine. Further node annotation was achieved through MolNetEnhancer, resulting in the classification of an additional 68 nodes into various molecular families. Consequently, this study represents a significant contribution to the identification of the D. phaseolorum metabolome, highlighting its secondary metabolites and providing valuable chemical insights to elucidate its demonstrated biological activities. lanceolatum antimicrobial leishmanicidal antitumoral properties constituents Therefore D tools annotated lipids benzenoids compounds nucleosides 4 3 references alismol farnesol acid tyramine Nacetyltyramine, Nacetyltyramine N acetyl N-acetyl-tyramine 5methoxy1Hindole3carbaldehyde, 5methoxy1Hindole3carbaldehyde methoxyHindolecarbaldehyde 5 methoxy 1H indole carbaldehyde, carbaldehyde H 5-methoxy-1H-indole-3-carbaldehyde 6pentyl2Hpyran2one, 6pentyl2Hpyran2one pentylHpyranone 6 pentyl 2H pyran 2 one, one 6-pentyl-2H-pyran-2-one adenosine Consequently Hindole Hpyran

Parthenolide (PTN) is a secondary metabolite of the plant Tanacetum parthenium (L.) Schulz Bip. and is considered the chemical marker of this species. This sesquiterpene lactone (germacrene skeleton) has been described as responsible for the biological activity of the leaf extract. In addition, several studies in the literature have demonstrated its antiparasitic and antineoplastic activity. However, there is a need for knowledge of other safety parameters, such as pharmacokinetic, pharmacodynamic and toxicity evaluations. Therefore, in this investigation, the in vitro metabolism of parthenolide was performed with rat liver microsomes and biomimetic metabolism (such as cytochrome P-450 system) using organometallic catalysts. The biomimetic procedure was validated since the major compound of biomimetic oxidative reaction with meta-chloroperbenzoic acid catalyzed by metalloporphyrin 5,10,15,20-tetrakis(pentafluorophenyl)-porphyrin iron(III) chloride was also observed with rat liver microsomes. Previous chemoenzymatic synthesis studies of PTN afforded the same epoxide formation, this major oxidative compound was isolated and fully characterized as (1 R,10R)-epoxyparthenolide based on experimental and theoretical calculations of infrared (IR) and vibrational circular dichroism (VCD) data at the B3PW91/6-311G. Furthermore, for the first time, this metabolite was evaluated for trypanocidal and leishmanicidal activity. The mean inhibitory concentration (IC50) values were lower for PTN than its metabolite and showed significant cytotoxic effects for both parasites. This finding holds promise for addressing neglected diseases. (PTN L. L (L.

In order to extract hesperidin from Citrus aurantium L. through green and efficient ways, a novel method based on deep eutectic solvent (DES) assisted extraction has been developed. Compared to known alkali extraction and acid precipitation or organic solvent (ethanol, methanol) extraction, this new DES system of choline chloride/diethanolamine (DES-14) method exhibited excellent extraction efficiency for hesperidin. Under optimal conditions, the extraction yield of hesperidin reached 6.26 ± 0.05%. Further studies with infrared spectroscopy, 1H nuclear magnetic resonance, and density functional theory showed the DES-14 was formed mainly through the interaction of H-bond and van der Waals forces. In addition, scanning electron microscopy and density functional theory revealed the strong dissolving capacity, and the H-bond formation between DES-14 and hesperidin, as well as van der Waals forces all contributed to efficient extraction of hesperidin. The results provide a new strategy for efficient extraction and utilization of hesperidin in Citrus.

The antifouling booster biocides are frequently studied for toxic effects on the aquatic ecosystems. The present investigation proposes passive silicone rubber samplers as a collection method for biocides, once these methods can concentrate substances in aqueous matrices at very low levels. Through the passive sampler-water partition coefficient (Ksw) and the analyte chemical nature, we can optimize their extraction from the membrane to apply in the sample medium. We used the co-solvent method to determine the Ksw of three third-generation antifouling biocides, chlorothalonil, dichlofluanid, and dichlorooctylisothiazolinone (DCOIT), with log Ksw = 2.24, 4.01, and 2.38, respectively. Improving extraction also led to a recovery range higher than 70%, determinations were carried out by gas chromatography with an electron capture detector. Biocides concentration in seawater samples from Itaqui port (São Marcos Bay, northern Brazil) ranged from 0.058 to 0.72 µg L-1 for chlorothalonil, 0.001 to 0.008 µg L-1 for dichlofluanid, and 0.018 to 0.64 µg L-1 for DCOIT. ecosystems levels samplerwater sampler water (Ksw nature medium cosolvent co solvent thirdgeneration third generation chlorothalonil dichlofluanid DCOIT, DCOIT , (DCOIT) 224 2 24 2.24 401 4 01 4.01 238 38 2.38 respectively 70 70% detector São Bay Brazil 0058 0 058 0.05 072 72 0.7 L1 L 1 L- 0001 001 0.00 0008 008 0018 018 0.01 064 64 0.6 (DCOIT 22 2.2 40 4.0 23 3 2.3 7 005 05 0.0 07 0. 000 00 06 6 2. 4.

Palicourea tomentosa (Aubl.) Borhidi (Rubiaceae, Palicoureeae), earlier classified as Psychotria poeppigiana Müll. Arg., is used in folk medicine for a variety of diseases. Biological studies on the plant describes their vasorelaxant, antiplasmodial, antitumoural and anticholinesterase activities. To expand the knowledge on the chemical and biological potential of this species, in this work, phytochemical and dereplication studies, as well as antimicrobial and anticholinesterase evaluation of Palicourea tomentosa were carried out. Phytochemical investigation deals with the isolation of lutein (1), a mixture of dehydrovomifoliol (2) and megastigma-4,7-dien-3-one (3), loliolide (4), 5,13-epoxy-9-hydroxy-megastigma-7-en,3-one (5), vomifoliol (6), asperuloside (7), 3-O-p-coumaroylquinic acid (8), and a mixture of the pyrrolizidinoindoline alkaloids hodgkinsine (9), chimonanthine (10) and psychotriasine (11). The ultra-high performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC HRMS/MS) based on molecular networking dereplication of dichloromethane fraction led to putative identification of other two megastigmanes, one terpene lactone and three carotenoids, besides seven triterpenes and four indole alkaloids. The dichloromethane, ethyl acetate and hydromethanol fractions of P. tomentosa were able to inhibit Candida albicans with minimum inhibitory concentrations (MICs) of 125, 250 and 125 µg mL-1, respectively. The methanol crude extract, dichloromethane and alkaloid fractions inhibited selectively the butyrilcholinesterase (BuChE) at percentages of 63.09, 60.39 and 56.22%, respectively. Aubl. Aubl (Aubl.

RESUMO: O estudo de adaptabilidade, estabilidade e produtividade é importante para selecionar e recomendar genótipos superiores. Esse fato é particularmente válido para a introdução de cultivares de feijão comum no Rio de Janeiro, Brasil, cuja produção é ínfima e não atende a demanda interna. Assim, este trabalho teve como objetivo estimar parâmetros genéticos e ganhos de seleção e realizar uma seleção simultânea para adaptabilidade, estabilidade e produtividade de genótipos de feijão preto através de modelos mistos. O estudo foi realizado em três municípios do estado do Rio de Janeiro e em três anos agrícolas. Os ensaios foram instalados em delineamento de blocos casualizados com 11 genótipos e três repetições. Observou-se alta herdabilidade média (81%), acurácia seletiva (90%) e boas perspectivas de seleção. Também foram observados ganhos satisfatórios para a característica entre 1,03 e 9,49%. A seleção simultânea foi eficiente e permitiu selecionar duas linhagens de feijão preto CNFP (15290 e 15361) como sendo as mais produtivas, adaptáveis e estáveis e, portanto, têm potencial para serem lançadas como novas cultivares de feijão preto para o estado do Rio de Janeiro.

ABSTRACT: The study of adaptability, stability, and productivity is essential for selecting and recommending superior genotypes. This fact is particularly the case for the introduction of common bean cultivars in Rio de Janeiro, Brazil, whose production is negligible and does not meet the internal demand. Thus, this study estimated genetic parameters and selection gains and undertake a simultaneous selection for adaptability, stability, and productivity in black bean genotypes via mixed models. The investigation was carried out in three municipalities in the state of Rio de Janeiro during three crop years. The trials were set up in a randomized block design with 11 genotypes and three replications. High mean heritability (81%) and selection accuracy (90%), as well as good selection prospects, were observed. Gains between 1.03 and 9.49% were achieved for grain yield. Simultaneous selection was efficient, indicating two black bean lines (CNFP 15290 and CNFP 15361) as the most productive, adaptable, and stable. As such, these lines have the potential to be released as new black bean cultivars for the state of Rio de Janeiro.

Abstract In order to widen the application fields of thermosetting composites, this research aims to identify the bioresins and biofibers more resistant to weathering, enabling their use outdoors. Data were collected from experimental research on composites made from synthetic or plant-derived matrix with plant or hybrid fibers, and using various molding processes, reinforcement geometries, alignment and treatment of fibers and fiber/matrix fractions. The investigation searched for researches that studied the composites tensile and flexural strengths; their water absorption in 24 hours of immersion and until saturation; and their retention of mechanical strength after aging. The effect of matrix and fiber types and their fractions on these properties was studied. Results indicate that composites with plant-derived matrix absorb less water in 24h, and that composites with flax, sisal or hemp have the lowest water absorption at saturation and the greater retention of tensile strength after aging. In other words, apparently these composites are less prone to weathering and thus have potential for outdoor use. However, regardless of the fiber type, as its content increases, the retention of flexural strength of composites decreases, limiting their usage in some applications. outdoors plantderived derived processes geometries fibermatrix strengths 2 aging 24h h flax words However type increases decreases applications

Resumo Buscando ampliar a aplicação dos compósitos termorrígidos, esta pesquisa objetiva identificar as bioresinas e biofibras mais resistentes às intempéries, contribuindopara seu uso externo. Foram levantadas pesquisas experimentais sobre compósitos com matriz sintética ou vegetal e fibras vegetais ou híbridas, com diferentes processos de moldagem, geometrias de reforço, alinhamento e tratamento das fibras e frações fibras/matriz. Buscou-se trabalhos que estudaram as resistências à tração e à flexão; a absorção de água dos compósitos em 24h de imersão e até a saturação; e sua retenção da resistência mecânica após envelhecimento. Investigou-se a influência do tipo de matriz e de fibra e de suas frações nessas propriedades. Resultados indicam que compósitos de matriz vegetal absorvem menos água em 24h, e que compósitos com linho, sisal ou cânhamo possuem a menor absorção de água na saturação e maior retenção da resistência à tração após o envelhecimento. Isto é, aparentemente esses compósitos sofrem menos danos devido às intempéries, possuindo maior potencial para uso externo. Mas, independentemente da fibra, conforme sua quantidade aumenta, diminui a retenção da resistência à flexão dos compósitos, limitando sua aplicação. termorrígidos intempéries externo híbridas moldagem reforço fibrasmatriz fibras/matriz Buscouse Buscou se h envelhecimento Investigouse Investigou propriedades linho é Mas aumenta

Abstract Cracking can be investigated by infrared thermography, as defects on a surface have different temperatures compared to regions without defects. The temperature of the crack depends on its dimensions, opening and depth, which can be identified by thermography. The possibility of classifying crack damage according to different depths by thermography in heating and cooling regimes and indicating which conditions are most suitable for identifying cracks is evaluated. It is proposed to observe the temperature evolution during the heating and cooling of a mortar slab that has cracks with different depths. The temperature variation of the plate during heating and cooling is monitored by thermograms and thermocouples present on the surface and interior of the plate in regions close to the cracks. It is identified, through the application of Delta-T thermographic contrast, that cracks of greater depth have a greater Delta-T, in modulus, during heating, while cracks of shallower depth have a greater Delta-T during cooling. Cracks are best identified during the cooling phase, as shallower cracks are not identified at the end of heating. dimensions evaluated DeltaT Delta T contrast DeltaT, T, modulus phase

Resumen En el presente artículo se indaga sobre la relación entre la migración y la política en Estados Unidos durante el período de 2000-2020. En específico, se examina el volumen de detenciones en función del partido gobernante a nivel estatal, a la vista de distintos eventos coyunturales y procesos socioeconómicos, con los datos del Departamento de Seguridad Nacional de Estados Unidos, por agencia participante. En cada apartado, distintas interrogantes guían la investigación: en primer lugar, ¿quiénes arrestan a inmigrantes en Estados Unidos?; en segundo, ¿qué agencia realiza más arrestos de indocumentados? y ¿dónde ocurren más arrestos, en la frontera o en el interior?; en tercer lugar, ¿qué papel juegan los gobiernos estatales según su afiliación política demócrata o republicana? Las tendencias principales y las diferencias se presentan en las conclusiones.

Abstract This article investigates the relationship between migration and politics in the United States during the period 2000-2020. Specifically, detention figures are examined in relation to the ruling party at the state level, in the context of different conjunctural events and socioeconomic processes, using data from the United States Department of Homeland Security, by participating agency. Different questions guide the investigation in each section: first, who apprehends immigrants in the United States?; Second, which agency makes the most apprehensions of undocumented immigrants?, and where do the largest number of apprehensions take place, at the border or inside the country?; Third, what role do state governments play depending on their political affiliation, Democrat or Republican? Main trends and differences are presented in the conclusions.

Abstract Introduction. Quinoa downy mildew is a disease that causes economic losses and has been poorly studied.Therefore, researching quinoa’s response to the disease and treatment methods is a topic that requires further investigation. Objective. To describe how downy mildew infection affects quinoa plants and the non-traditional methods used to control this disease. Development. A systematic search was conducted to compile the results associated with P. variabilis in quinoa (Chenopodium quinoa Wild.) under various conditions. The analysis determined that factors such as incidence, severity, and disease tolerance depended largely on the quinoa grain variety and altitude (along with its climatic conditions). Plant height and yield per hectare were influenced by soil conditions, pest and disease treatment, and the planting day. Conclusions. The incidence and severity of downy mildew depended on the quinoa variety used. Other factors such as altitude or humidity also influenced disease progression, with infection rates close to 90 % in high humidity environments. Non-conventional methods for treating downy mildew included plant infusions such as chamomile and garlic, showing positive short-term results; however, they did not surpass conventional treatments with chemical fungicides.

Resumen Introducción. El mildiu de la quinua es una enfermedad que ocasiona pérdidas económicas y que ha sido poco estudiada, por lo que la investigación de la respuesta de la quinua a la enfermedad y las formas de tratamiento es un tema que debe investigarse con mayor profundidad. Objetivo. Describir cómo afecta la infección del mildiu velloso en la planta de la quinua y los métodos no tradicionales empleados en el control de esta enfermedad. Desarrollo. Se realizó una búsqueda sistemática a fin de realizar una recopilación de los resultados asociados al P. variabilis en la quinua (Chenopodium quinoa Wild.) en diversas condiciones. El análisis determinó que factores como la incidencia, la severidad y la tolerancia a la enfermedad del mildiu, dependieron en gran medida de la variedad de grano de quinua y la altitud (con sus condiciones climáticas). La altura de la planta y el rendimiento por hectárea estuvieron influenciados por las condiciones del suelo, el tratamiento empleado contra plagas y patógenos, y el día de siembra. Conclusiones. La incidencia y la severidad del mildiu velloso dependió de la variedad de la quinua con la que se trabajó. Otros factores como la altitud o la humedad también influyeron en el progreso de la enfermedad, con una infección cercana al 90 % en ambientes con alta humedad. Los métodos no convencionales para tratar el mildiu fueron infusiones de plantas como la manzanilla y el ajo, con resultados positivos a corto plazo; no obstante, no superaron a los tratamientos convencionales con fungicidas químicos.

Abstract: This investigation proposes to develop a methodology based on the mean-variance mapping optimization (MVMO) algorithm to reduce the active power losses of the subtransmission system of the Electric Company Quito (EEQ), determining the best operating point of the system, considering the state of taps of the transformers, the capacitor banks and the contribution of reagents from the generation plants that the company currently has. EEQ. The same ones that, when operating in an adequate manner, lead to reducing the value of active power losses in the network, thus improving the operating conditions of the EEQ Electrical Power System.

Resumen: Esta investigación propone desarrollar una metodología basada en el algoritmo de optimización de mapeo media varianza (MVMO) para reducir las pérdidas de potencia activa del sistema de subtransmisión de la Empresa Eléctrica Quito (EEQ), determinando el mejor punto de operación del sistema, considerando el estado de tap’s de los transformadores, los bancos de capacitores y del aporte de reactivos de las centrales de generación con las que cuenta actualmente la EEQ. Los mismos que al operar de una manera adecuada llevan a reducir el valor de las pérdidas de potencia activa en la red, mejorando así las condiciones operativas del Sistema Eléctrico de Potencia de la EEQ.

Abstract This article intends to analyze innovative projects that have been successful in the promotion of sustainable development and improvement in quality of life of indigenous communities in Mexico. Three projects are considered: eco-touristic park, communal house and agro-businesses in the indigenous community of Tlajomulco (Jalisco), to study the scope and limitations of social innovation in the promotion of sustainable local development. A qualitative methodology was used involving participative investigation-action. The findings show that collaboration is essential to achieve success in such projects, but they do not depend exclusively on the existence of trust and mutual benefit between the parties involved as literature suggests, but also the capacity to transcend individual interests and work jointly towards attaining collective interests that promote sustainable development of the community. This finding represents a contribution to specialized literature in the area and calls to reflection and action to promote effective collaborative practices in the field of sustainable local development.

Resumen Este artículo tiene como objetivo analizar proyectos innovadores que han sido exitosos en el fomento del desarrollo sostenible y en el mejoramiento de la calidad de vida de comunidades indígenas en México. Se consideran tres proyectos: parque ecoturístico, casa comunal y agronegocios en la comunidad indígena de Tlajomulco (Jalisco), para estudiar los alcances y limitaciones de la innovación social en la promoción del desarrollo local sostenible. Se utilizó una metodología cualitativa con investigación-acción participativa. Los hallazgos constatan que la colaboración resulta crucial para lograr el éxito de proyectos, pero no dependen exclusivamente de la existencia de confianza y beneficio mutuo entre los actores involucrados, como lo sugiere la literatura, sino también depende de la capacidad para trascender los intereses individuales y trabajar en conjunto hacia la consecución de intereses colectivos que promuevan el desarrollo sostenible de la comunidad. Este hallazgo representa un aporte a la literatura especializada en el campo y hace un llamado a la reflexión y la acción para promover prácticas colaborativas efectivas en el ámbito del desarrollo local sostenible.

Consideraram-se três projetos: parque eco turístico, casa comunal e agronegócios na comunidade indígena de Tlajomulco (Jalisco) para o estudo dos alcances e limitações da inovação social na promoção do desenvolvimento local sustentável. Usou-se uma metodologia qualitativa com pesquisa-ação participativa. As conclusões da pesquisa verificaram que a colaboração é essencial para que os projetos sejam exitosos, mas sem depender exclusivamente da existência de confiança e benefícios mútuos dos atores involucrados do jeito que sugeriu a literatura, mas também da capacidade para transcender os interesses individuais e trabalhar conjuntamente para a realização dos interesses coletivos que fomentem o desenvolvimento sustentável da comunidade. Isso representa uma contribuição à literatura especializada da área e chama a refletir e agir para promover práticas colaborativas efetivas boas no campo do desenvolvimento local sustentável.

Abstract This article brings light to one of the phases of doctorate-level investigation on the role of the universities in Ecuador for the social innovation process. The objective is to identify investigation projects performed with participation of Ecuadorian universities from the approach of social management with several actors involved. A systematic literature-based mapping was used to choose and analyze 33 publications to identify investigation performed with participative methodologies such as co-design, co-production or investigation-action. The databases WoS and Scopus were used, with results showing that there is a limited number of investigation applying co-design, no investigations with co-production, and most of the articles studies report to have used investigation-action. Several projects that imply participation of the community related to the issue were presented in most cases. This mapping presented 12 projects that align with the social innovation process, applying methods and techniques that promote actor participation, which also supports the understanding of how universities may fulfill their substantive function of performing research while responding to contextualized social needs.

Resumen Este artículo expone una de las fases de la investigación doctoral sobre el rol de las universidades ecuatorianas en el proceso de innovación social. El objetivo es identificar proyectos de investigación que se han realizado con la participación de universidades ecuatorianas desde el enfoque de la gestión social e integran diversos actores. Mediante un mapeo sistemático de literatura se seleccionaron y analizaron 33 publicaciones para identificar investigaciones realizadas con metodologías participativas como codiseño, coproducción o investigación-acción. Se usaron las bases de datos WoS y Scopus; los resultados muestran que existen limitadas investigaciones que apliquen codiseño, no se identifican investigaciones de coproducción, mientras la mayoría de los artículos analizados reportan haber aplicado investigación-acción. Se presentan diferentes proyectos que implican la participación de la comunidad relacionada con la problemática que se intenta resolver en la mayoría de los casos. Este mapeo permitió encontrar doce proyectos que se alinean al proceso de innovación social, aplicando métodos y técnicas que fomentan la participación de los actores, lo que aporta en la comprensión de cómo las universidades pueden cumplir su función sustantiva de investigación respondiendo necesidades sociales contextualizadas.
