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.

The Schröeder-van Laar equation to predict the theoretical eutectic melting temperature values was applied to a set of fourteen binary mixtures (UR1 to UR14). The fourteen binary mixtures belong to a structurally diverse group of organic molecules. They are represented by the 5-membered heterocycles containing N-S and N-O rings, flexible methylene chains (RH), semi-rigid semi-fluorinated chains (RF), and hydrogen bonds (HB). A virtual screening totalizing ninety-one possible theoretical combinations was planned. The UR1 to UR14 were prepared by mixing individual components using the calculated mole fractions. The experimental (Te) and theoretical (Tt) temperatures for the eutectic melting points were determined using polarized optical microscopy (POM) and differential scanning calorimetry (DSC) techniques. Heterogeneous mixtures were formed for components with large structural diversity as seen by POM. During the melting of the mixtures, irregular behavior through the segregation of the components was recorded. The study showed that the similarities in structural diversities favor the formation of homogeneous mixtures, with Te values approaching Tt, as predicted by the Schröeder-van Laar equation and by the theory of eutectic mixtures. Liquid crystal properties were affected in homogeneous binary mixtures containing one of the individual liquid crystal components. Schröedervan Schröeder van UR (UR UR14. .

High-density polyethylene (HDPE) geomembranes are commonly used as an environmental protection liner due to their good chemical and mechanical resistances and low cost. Ultraviolet (UV) radiation is an essential issue in durability studies for pond applications. This study evaluated a 1.5-mm thick HDPE geomembrane exposed to ultraviolet fluorescent radiation for 8760 h in a laboratory and thermoanalytical and physical analyses were conducted towards the understanding of its performance after exposure. According to the results, although the geomembrane maintained the ductile behavior, it showed a 52.48% final decrease in stress crack resistance (SCR) compared to virgin SCR. Moreover, a considerable antioxidant depletion occurred after 8760 h exposure shown by the Std. OIT (standard oxidative-induction time) results, demonstrating a Std. OIT value decrease of 89.19% compared to the virgin Std. OIT. Such a behavior contributed to the susceptibility of thermal effects in the DSC (differential scanning calorimetry) curves and the losses observed in the SCR values, attesting the geomembrane’s oxidative degradation mechanism occurred and changed the polymer’s structure.

Lantana caatingensis Moldenke (Verbenaceae) is an endemic plant from northeastern Brazil. However, its chemical composition is almost unknown. This study aimed to characterize the chemical compounds found in L. caatingensis and investigate the antileishmanial potential of its hydroalcoholic extract and polar fractions. Compounds present in the hydroalcoholic extract obtained from L. caatingensis leaves and its polar fractions (ethyl acetate and methanolic) were analyzed by liquid chromatography with a photodiode-array detector coupled to electrospray ionization quadrupole time-of-flight mass spectrometry. An antileishmanial assay was performed in a 96-well plate against Leishmania major promastigotes using resazurin on a plate spectrophotometer and the results were expressed as percentage of growth inhibition. Nine compounds were determined in the investigated extract and fractions, classified as flavonoids, flavonoid C-glycosides and phenylethanoid glycosides. The antileishmanial activity revealed that the hydroalcoholic extract and the ethyl acetate fraction were active against L. major promastigotes with inhibitory concentration of 71.78 and 26.86 µg mL-1, respectively, while the methanolic fraction was inactive (478.40 µg mL-1). This is the first report on the chemical composition and antileishmanial activity of L. caatingensis extracts. These results contribute to further knowledge of species belonging to the Lantana genus.

ABSTRACT Planting is considered one of the most essential steps in coffee growing. Lack of uniformity in planting may compromise future operations. Therefore, verifying planting operations quality is fundamental to optimizing production processes and reducing costs. This study aimed to investigate planting techniques through Statistical Process Control (SPC) and aerial images. Carried out in two areas, managed manually and semi-mechanized in the Bom Jardim Farm (MG - Brazil). Data were collected through Remotely Piloted Aircraft (RPA). Quality control charts and density maps were used to identify variations in distribution and spacing between plants and planting rows. It was found that the planting carried out manually was 4.7% wider than projected due to spacing reduction from 0.5 m to 0.48 m. The semi-mechanized system displayed a deficit of 7% compared to the projected planting system, using 0.55 m between plants. The density map showed the most significant planting alignment variations. Despite displaying lower results than the manual system, the semi-mechanized system improvements are valid for their minimal average variations. Thus, correcting points found outside the limits can increase the efficiency of semi-mechanized planting. growing Therefore costs SPC (SPC images areas semimechanized semi mechanized MG Brazil.

ABSTRACT Biochar can promote crop production and soil quality. However, its characteristics depend on the waste used in its production and its effects may vary according to the species being cultivated and the management adopted. The aim of this study was to evaluate the application of biochar from animal waste on soil quality and the agronomic characteristics of the cowpea. An experiment was set up to test three types of biochar (bovine-BB, swine-SB and poultry-BP), with added fertiliser (BBF, SBF and BPF) and two control treatments, including the addition of calcium magnesium oxide (CT) and calcium magnesium oxide with fertiliser (CTF), giving a total of eight treatments with four replications. There was a respective increase of up to 102.94%, 1048%, 1560% and 360.22% in stem diameter, number of pods, number of grains per pod and stem dry matter from adding the biochar. The poultry biochar increased each of the above parameters even with no added fertiliser. There was no difference in basal soil respiration or β-glucosidase enzyme activity, whereas organic carbon (TOC), total nitrogen (TN), microbial carbon and soil labile carbon were greater with biochar. BBF gave the highest TOC content (24.40 g kg-1), while BP and BPF increased TN by around 61%. The application of biochar + fertiliser contributed to an average reduction of 56% in the soil metabolic quotient. Poultry biochar favoured both the agronomic characteristics of the cowpea and soil quality, while bovine biochar showed more marked results with the addition of fertiliser.

ABSTRACT Purpose: This study aimed to compare the safety and effectiveness of intraocular pressure reduction between micropulse transscleral cyclophotocoagulation and “slow cook” transscleral cyclophotocoagulation in patients with refractory primary open-angle glaucoma. Methods: We included patients with primary open angle glaucoma with at least 12 months of follow-up. We collected and analyzed data on the preoperative characteristics and postoperative outcomes. The primary outcomes were a reduction of ≥20% of the baseline value (criterion A) and/or intraocular pressure between 6 and 21 mmHg (criterion B). Results: We included 128 eyes with primary open-angle glaucoma. The preoperative mean intraocular pressure was 25.53 ± 6.40 and 35.02 ± 12.57 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean intraocular pressure was reduced significantly to 14.33 ± 3.40 and 15.37 ± 5.85 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups at the last follow-up, respectively (p=0.110). The mean intraocular pressure reduction at 12 months was 11.20 ± 11.46 and 19.65 ± 13.22 mmHg in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The median preoperative logMAR visual acuity was 0.52 ± 0.69 and 1.75 ± 1.04 in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean visual acuity variation was −0.10 ± 0.35 and −0.074 ± 0.16 in the micropulse- and “slow cook” transscleral cyclophotocoagulation, respectively (p=0.510). Preoperatively, the mean eye drops were 3.44 ± 1.38 and 2.89 ± 0.68 drugs in the micropulse- and “slow cook” transscleral cyclophotocoagulation groups, respectively (p=0.017), but those were 2.06 ± 1.42 and 1.02 ± 1.46 at the end of the study in the “slow cook” and micropulse transscleral cyclophotocoagulation groups, respectively (p<0.001). The success of criterion A was not significant between both groups. Compared with 11 eyes (17.74%) in the “slow cook” transscleral cyclophotocoagulation group, 19 eyes (28.78%) in the micropulse transscleral cyclophotocoagulation group showed complete success (p=0.171). For criterion B, 28 (42.42%) and 2 eyes (3.22%) showed complete success after micropulse- and “slow cook” transscleral cyclophotocoagulation, respectively (p<0.001).

Abstract The identification of anomalies for damage mapping is a complex task that depends on knowledge of their manifestation. The purpose of this study is to propose criteria for detecting anomalies in mortar coatings by analyzing facade images, aiming to improve damage mapping. Specific parameters related to position (geometry), configuration, grouping, origin and nearby construction componentes are proposed to guide the identification of each damage, indicating what is most important to observe in each case. To apply the proposed method, six sections of building facades in Brasília - DF are selected. The main characteristics that aid in identifying the typology of each anomaly are obtained, and the applied methodology validates the proposed approach. The results show that the established criteria lead to precise anomaly identification, making the damage mapping process more efficient and reliable, contributing to the study of degradation. manifestation images geometry, geometry , (geometry) configuration grouping case method selected obtained approach reliable degradation (geometry

Abstract Construction projects are highly complex systems that recurrently present discrepancies between work-as-imagined and work-as-done. Digital technologies, such as photogrammetry using UAVs (drones), are promising support tools to cope with this problem. Therefore, this study aims to evaluate the procedures for developing and assessing the quality of a 3D model generated through photogrammetry from images captured by a drone, comparing it to the as-designed BIM model. Thus, a case study was carried out in a residential low-income housing construction project in Camaçari, Brazil. Compared to the as-designed BIM 3D model, the photogrammetric model presented an average dimensional deviation of -1.68%. The model also presented issues such as occlusions and deformations. The study highlights that both this deviation and the quality of the photogrammetric model can be significantly influenced by the data collection method (e.g., quantity and resolution of photos). The study's primary contribution lies in presenting the potential of UAV usage for image capture in photogrammetry model generation. workasimagined work imagined workasdone. workasdone done. done work-as-done technologies drones, drones , (drones) problem Therefore D drone asdesigned designed Thus lowincome low income Camaçari Brazil 1.68%. 168 1 68 -1.68% deformations e.g., eg e g (e.g. photos. photos . photos) studys s generation (drones 1.68% 16 6 -1.68 e.g. (e.g 1.68 -1.6 e.g 1.6 -1. 1. -1 -

Resumo Projetos de construção são sistemas altamente complexos que apresentam recorrentemente discrepâncias entre o trabalho planejado e o trabalho realizado. Tecnologias digitais, como a fotogrametria com VANTs (drones), são ferramentas de suporte promissoras nesse contexto. Assim, este estudo tem como objetivo avaliar os procedimentos de desenvolvimento e qualidade de um modelo 3D gerado por fotogrametria através de imagens capturadas por drone, comparando-o ao modelo as-designed BIM. Para isso, realizou-se um estudo de caso em uma habitação de interesse social localizada em Camaçari-BA. Comparado ao modelo BIM projetado, o modelo fotogramétrico apresentou um desvio dimensional médio de -1,68%. O modelo também apresentou inconsistências como oclusões e deformações. O estudo mostra que tanto esse desvio como a qualidade do modelo fotogramétrico obtido podem ser consideravelmente influenciados pela forma de coleta dos dados (ex. baixa quantidade e resolução das fotos).

Abstract The improper disposal of this waste poses environmental challenges, which can be addressed through effective reuse strategies. This study aims to explore the potential of utilizing marine shell waste as partial substitutes for aggregates in concrete. The research involves investigating the physical characteristics of the recycled aggregate using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) techniques to elucidate the contact surface with the paste. Additionally, chemical and mineralogical characteristics are analyzed through X-ray fluorescence and X-ray diffraction tests. The compressive strength test is conducted on concrete samples to assess the performance of these materials as both aggregate (shell type A) and filler (shell type B). The findings indicate that replacing up to 20% of marine shells as coarse aggregate and 10% as filler demonstrates feasibility for applications in structural concrete. Furthermore, up to 30% replacement can be directed towards non-structural concrete, providing a comprehensive understanding of the potential applications of marine shell residues in concrete production. challenges strategies AFM (AFM SEM (SEM paste Additionally Xray X ray tests A B.

Resumo A produção de tintas utilizando resíduos de beneficiamento de granito e mármore é uma nova alternativa para contribuir com o desenvolvimento sustentável na construção civil. Entretanto, a carência de estudos sobre a composição e o desempenho dessas tintas inviabiliza a disseminação desse novo material de construção. Logo, este estudo tem como objetivo investigar a composição dessas tintas utilizando ferramentas estatísticas para obter produtos com desempenho compatível com regulamentações técnicas e tintas comerciais. As formulações de tintas foram definidas através de um planejamento de misturas quaternárias. O teor de sólidos, pH, viscosidade, poder de cobertura e resistência à abrasão foram determinados para todas as amostras. As tintas produzidas com resíduos de granito apresentaram melhor poder de cobertura e resistência à abrasão, pois o resíduo de granito apresenta granulometria mais fina, além de ser predominantemente composto por sílica. Por fim, as tintas produzidas neste estudo e as tintas comerciais apresentaram comportamento semelhante, o que corrobora com o aproveitamento do resíduo do processamento de rochas ornamentais na produção de tintas. civil Entretanto Logo quaternárias sólidos pH viscosidade amostras fina sílica fim semelhante

Abstract The production of paints using waste from granite and marble processing is a new alternative to contribute to sustainable development in civil construction. However, the lack of studies on the composition and performance of these paints makes the dissemination of this new construction material unfeasible. Therefore, this study aims to investigate the composition of these paints using statistical tools to obtain products with performance compatible with technical regulations and commercial paints. The paint formulations were defined through a quaternary mixture planning. The solids content, pH, viscosity, hiding power, and abrasion resistance were determined for all samples. The paints produced with granite waste showed better hiding power and abrasion resistance, as granite waste has a finer granulometry, in addition to being predominantly composed of silica.

Resumen: Este trabajo se basa en el supuesto de que, si bien las propuestas de políticas institucionales para combatir la violencia contra las mujeres han avanzado en Brasil, principalmente debido a las acciones y reflexiones del activismo feminista producidas en el campo de los estudios feministas, existe una brecha en términos de propuestas de políticas efectivamente elaboradas. y los debates producidos por los feminismos negros sobre raza y clase. En ese sentido, a partir del análisis de 36 proyectos de ley de la Cámara de Diputados que se presentaron entre 2011 y 2022 y se convirtieron en normas jurídicas, observaremos los avances y limitaciones desde la perspectiva de los feminismos negros. Los resultados muestran que, a pesar del impacto inequívoco de las agendas feministas en el Poder Legislativo, el conjunto de leyes recientemente redactadas refleja las demandas del feminismo liberal y hegemónico, que tienden a producir una lectura unidimensional de las mujeres, desconsiderando los efectos de las inseparables vínculo entre género, raza y clase.

Abstract: This work is based on the assumption that, although institutional policy proposals to combat violence against women have advanced in Brazil, mainly due to activism actions and reflections produced in the field of feminist studies, there is a gap in terms of propositions effectively crafted policies and the debates produced by black feminisms. In this sense, based on the analysis of 36 proposals of the Chamber of Deputies that were presented between 2011 and 2022 and became legal norms, we will observe the advances and limitations from the perspective of black feminisms. The results show that, despite the unequivocal impact of feminist agendas in the Legislative Branch, the set of recently drafted laws reflects the demands of liberal and hegemonic feminism, which tend to produce a one-dimensional reading of women, disregarding the effects of the inseparable link between gender, race and class.
