In silico and in vitro tests can reveal promising anti-leishmania activity for natural products and their derivatives. The aim of this study was to investigate in silico the pharmacological activities of potential new chalcones and their leishmanicidal potential in vitro. The in silico study was carried out using the PASS, MolPredictX and Molegro Virtual Docker 6.0 programs. Antiparasitic activity was assessed in axenic promastigote and amastigote forms of Leishmania braziliensis. The cytotoxicity tests used the J77G8 cell line. The chalcones exhibited 50% cytotoxic concentration values (CC50) values > 50 μM. Chalcone 4 (named FERAI) presented the best activity with concentration for 50% of promastigotes and intracellular parasites forms (EC50) of 9.75 ± 1.7 and 10.13 ± 1.7 μM for promastigote and amastigote, respectively. Reactive oxygen species (ROS) testing presented increased ROS levels in the parasite at the FERAI concentrations of 10 μM (56.33%), 20 μM (61.76%) and 30 μM (67.13%). Molecular docking revealed interactions (binding energy) between FERAI and the enzymes UDP-glycosyl pyrophosphorylase (-56.8384), dihydroorotate-dehydrogenase (-132.276) and trypanothione-reductase (-151.281). Our results demonstrated the anti-leishmanial activity of chalcones, especially FERAI, with a noted raising of ROS levels in the parasite.

Abstract The potential of H. virginiana L. was evaluated against Candida spp. (C. albicans, C. dubliniensis, C. glabrata, C. guilliermondii, C. krusei, and C. tropicalis) and bacteria (Acinetobacter baumannii, Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Staphylococcus aureus, and Streptococcus mutans). Effect on murine macrophages (RAW 264.7) was also evaluated with respect to cytotoxicity and production of cytokines (IL-1β and TNF-α) and nitric oxide (NO). The most effective concentrations of the extract were determined by microdilution broth. These concentrations were analyzed on biofilms, after 5 min or 24 h exposure. Cytotoxicity was performed by MTT assay and quantification of cytokines and NO by ELISA and Griess reagent, respectively. The extract acted against the planktonic forms and provided significant reductions of all the microbial biofilms; besides, showed no cytotoxic effect, except at 100 mg/mL, after 24 h exposure. There was cytokine production; however, a modulatory effect was observed in groups exposed to lipopolysaccharide (LPS) from E. coli. NO production was similar or higher than the control group. Thus, H. virginiana L. extract showed antimicrobial and antibiofilm effects; absence of cytotoxicity for RAW 264.7; anti-inflammatory action; and potential to fight infections through the NO production.

RESUMO: Astrocaryum murumuru é uma palmeira típica de áreas de várzea amazônica, cujas sementes são exploradas extrativamente para a fabricação de cosméticos. A germinação da espécie é demorada, evidenciando a necessidade de desenvolvimento de técnicas que acelerem este processo. Desse modo, esta pesquisa objetivou avaliar a germinação e o vigor de sementes de A. murumuru, submetidas a diferentes condições térmicas de estratificação. O delineamento experimental adotado foi o inteiramente casualizado, com quatro tratamentos (diferentes condições térmicas) e quatro repetições. Após a secagem dos diásporos, extração e embebição das sementes, estas (com grau de umidade de 26,8%) foram acondicionadas em sacos plásticos duplos contendo vermiculita, umedecida com água o equivalente a 60% de sua massa seca. Em seguida, foram mantidas nas seguintes condições: ambiente natural (27,8 ± 2,7 °C); estufa com temperatura de 40 °C, por 3 horas, por dia; estufa com temperatura de 40 °C, por 6 horas, por dia; e estufa com temperatura de 40 °C, por 9 horas, por dia. A estratificação sob temperatura a 40 °C/3 horas/dia proporciona melhor desempenho germinativo e de desenvolvimento inicial de plântulas de A. murumuru (51%), além de redução das sementes remanescentes dormentes (25%) e mortas (24%).

ABSTRACT: Astrocaryum murumuru is a palm tree typical of Amazonian lowland areas (floodplains), whose seeds are exploited extractively for the manufacture of cosmetics. Germination of the species takes time, highlighting the need to develop techniques that shorten this process. Therefore, this research aimed to evaluate the germination and vigor of A. murumuru seeds, subjected to different thermal conditions of stratification. The experimental design adopted was completely randomized, with four treatments (different thermal conditions) and four replications. After drying the diaspores, extracting and soaking the seeds, these (with moisture content of 26.8%) were placed in double plastic bags containing vermiculite, moistened with water equivalent to 60% of their dry mass. They were then maintained under the following conditions: natural environment (27.8 ± 2.7 °C); oven with a temperature of 40 °C for 3 hours per day; oven with a temperature of 40 °C for 6 hours per day; and oven with a temperature of 40 °C for 9 hours a day. Stratification at a temperature of 40 °C/3 hours/day provides better germination performance and initial development of A. murumuru seedlings (51%), in addition to reducing remaining dormant (25%) and dead (24%) seeds.

ABSTRACT In 2000, Cleide Costa published a paper presenting the state of knowledge of the Neotropical Coleopte ra, with a focus on the Brazilian fauna. Twenty-four years later, thanks to the development of the Coleoptera section of the Taxonomic Catalog of the Brazilian Fauna (CTFB - Catálogo Taxonômico da Fauna do Brasil) through the collaboration of 100 coleopterists from all over the globe, we can build on Costa’s work and present an updated overview of the state of knowledge of the beetles from Brazil. There are currently 35,699 species in 4,958 genera and 116 families known to occur in the country, including representatives of all extant suborders and superfamilies. Our data show that the Brazilian beetle fauna is the richest on the planet, concentrating 9% of the world species diversity, with some estimates accounting to up to 15% of the global total. The most diverse family in numbers of genera is Cerambycidae (1,056 genera), while in number of species it is Chrysomelidae (6,079 species). Conotrachelus Dejean, 1835 (Curculionidae) is the most species-rich genus, with 570 species. The French entomologist Maurice Pic is the author who has contributed the most to the naming of species recorded from Brazil, with 1,794 valid names in 36 families, whereas the Brazilians Ubirajara R. Martins and Maria Helena M. Galileo are the only ones among the top-ten authors to have named species in the 21st century. Currently, approximately 144 new species of Brazilian beetles are described each year, and this average is projected to increase in the next decade to 180 species per year, or about one new Brazilian beetle every two days. 2000 ra Twentyfour Twenty four later CTFB Brasil 10 globe Costas s Brazil 35699 35 699 35,69 4958 4 958 4,95 11 country superfamilies planet 9 diversity 15 total 1,056 1056 1 056 (1,05 genera, , genera) 6,079 6079 6 079 (6,07 . species) Dejean 183 Curculionidae (Curculionidae speciesrich rich genus 57 1794 794 1,79 3 R M topten top ten st century Currently 14 year 18 days 200 3569 69 35,6 495 95 4,9 1,05 105 05 (1,0 6,07 607 07 (6,0 5 179 79 1,7 20 356 35, 49 4, 1,0 0 (1, 6,0 60 (6, 17 7 1, 2 (1 6, (6 (

Abstract Introduction The aberrant expression of the inhibitor of DNA binding (ID1) gene has been frequently associated with the leukemogenesis and prognostication acute myeloid leukemia (AML), although its clinical importance has never been investigated in patients treated outside well-controlled clinical trials. Methods Using quantitative real-time polymerase chain reaction, we investigated the role of the ID1 expression in the clinical outcomes of non-selected patients with acute myeloid leukemia treated in a real-life setting. Results Overall, 128 patients were enrolled. Patients with high ID1 expression had a lower 3-year overall survival (OS) rate of 9%, with the 95% confidence interval (95%CI) at 3 to 20%, compared to patients with a low ID1 expression (22%, 95%CI: 11 - 34%) (p = 0.037), although these findings did not retain significance after adjustment (hazard ratio (HR): 1.5, 95%CI: 0.98 - 2.28; p = 0.057). The ID1 expression had no impact on post-induction outcomes (disease-free survival, p = 0.648; cumulative incidence of relapse, p = 0.584). Conclusions Although we are aware thar our data are confronted with many variables that cannot be fully controlled, including drug unavailability, risk-adapted treatment, comorbidities and the time from diagnosis to treatment initiation, we are firm believers that such an initiative can provide more realistic data on understudied populations, in particular those from low- and middle-income countries.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract. Electrochemical oxidation (EO) has been investigated as an alternative treatment technique for the remediation of real textile effluents containing a single dye and a trichromy of Remazol Yellow 3RS (RY 3RS), Remazol Red RR Gran (RR-RR Gran) and Navy Blue CL-R (NB CL-R) dyes, using a parallel plate flow reactor equipped with Ti/Pt or Ti/Pt-Sn-Sb electrocatalytic materials and Ti as cathode. The influence of the anode material and applied current densities on decolourization, organic matter decrease, cell potential and energy consumption during EO was examined. Higher color removal was achieved with Ti/Pt-Sn-Sb in all treated effluents compared to Ti/Pt at all electrolysis times, due to high oxidant production, especially hydroxyl radicals on their surface. Polymer film formation on the anode surface inhibited chemical oxygen demand (COD) removal during the treatment of a single effluent containing RY 3RS and RR-RR Gran dyes with either anode, whereas COD removal efficiencies of 13.93 % and 30.03 %, and 54.74 % and 74.48 % were obtained for Ti/Pt and Ti/Pt-Sn-Sb, respectively, in treating trichromy effluent after 240 min of electrolysis. Lower energy consumption was required by Ti/Pt-Sn-Sb compared to the Ti/Pt anode. In most of the trials studied, EO enhanced dissolved oxygen (DO) and reduced effluent turbidity, making it safe for disposal in the environment.
Resumen. La oxidación electroquímica (EO) se ha investigado como una técnica de tratamiento alternativa para la remediación de efluentes textiles reales que contienen un solo tinte y una tricromía de Remazol Yellow 3RS (RY 3RS), Remazol Red RR Gran (RR-RR Gran) y Navy Blue CL -R (NB CL-R), utilizando un reactor de flujo de placas paralelas equipado con materiales electrocatalíticos Ti/Pt o Ti/Pt-Sn-Sb y Ti como cátodo. Se examinó la influencia del material del ánodo y las densidades de corriente aplicadas sobre la decoloración, la reducción de materia orgánica, el potencial de celda y el consumo de energía durante la EO. Se logró una mayor remoción de color con Ti/Pt-Sn-Sb en todos los efluentes tratados en comparación con Ti/Pt en todos los tiempos de electrólisis, debido a la alta producción de oxidantes, especialmente radicales hidroxilos en su superficie. La formación de una película de polímero en la superficie del ánodo inhibió la eliminación de la demanda química de oxígeno (DQO) durante el tratamiento de un solo efluente que contenía colorantes RY 3RS y RR-RR Gran con cualquiera de los ánodos, mientras que las eficiencias de eliminación de DQO del 13,93 % y 30,03 %, y del 54,74 % y Se obtuvo 74,48 % para Ti/Pt y Ti/Pt-Sn-Sb, respectivamente, en el tratamiento de efluentes de tricromía después de 240 min de electrólisis. El Ti/Pt-Sn-Sb requería un menor consumo de energía en comparación con el ánodo de Ti/Pt. En la mayoría de los ensayos estudiados, el EO mejoró el oxígeno disuelto (OD) y redujo la turbidez del efluente, haciéndolo seguro para su eliminación en el medio ambiente.

Abstract Introduction: Native Forest resources, mainly in the Brazilian caatinga biome, are important for the subsistence of the rural population as well as for the local red ceramic and gypsum industry. Objective: To study the municipal disparity in the gross value of production of native timber products in Paraíba, Brazil. Materials and methods: Data on the gross value of production (GVP) of forest products (firewood, charcoal and roundwood) of the municipalities of Paraíba, Brazil, from 1994 to 2017 were used. This information is available from the Brazilian Institute of Geography and Statistics (IBGE). Location indicators (location and redistribution coefficients) and specialization indicators (specialization and restructuring coefficients) were used. Results and discussion: Firewood was the main timber product in the municipalities of Paraíba and there was a substitution effect between firewood and charcoal; the latter showed the best state redistribution and roundwood the lowest municipal production. The greatest specialization occurred in the municipality of Baía da Traição, represented by the exclusive production of charcoal. The municipalities of Tacima, Salgado de São Félix and Itapororoca showed greater restructuring, resulting from the change from charcoal to firewood production. Conclusions: Firewood is the most important product in the state of Paraíba, Brazil. This study becomes an important source of information for the use of this resource.
Resumen Introducción: Los recursos forestales nativos, principalmente en el bioma caatinga brasileño, son importantes para la subsistencia de la población rural como para la industria local de cerámica roja y yeso. Objetivo: Analizar la disparidad municipal en el valor bruto de producción de productos madereros nativos en Paraíba, Brasil. Materiales y métodos: Se utilizaron datos sobre el valor bruto de producción (VBP) de productos forestales (leña, carbón y madera en rollo) de los municipios de Paraíba, Brasil, de 1994 a 2017. Esta información está disponible en Instituto de Geografía y Estadística Brasileñas (IBGE). Se utilizaron indicadores de ubicación (coeficientes de ubicación y redistribución) y de especialización (coeficientes de especialización y de reestructuración). Resultados y discusión: La leña era el principal producto maderero en los municipios de Paraíba y existía un efecto de sustitución entre leña y carbón vegetal; este mostró la mejor redistribución estatal, y la madera en rollo, la menor producción municipal. La mayor especialización se dio en el municipio de Baía da Traição, representado por la producción exclusiva de carbón vegetal. Los municipios de Tacima, Salgado de São Félix e Itapororoca presentaron mayor reestructuración, debido al cambio de la producción de carbón vegetal a la de leña. Conclusiones: La leña es el producto más importante en el estado de Paraíba, Brasil. Este trabajo se convierte en una fuente importante de información para el uso del recurso maderero.

Abstract Acmella bellidioides (Asteraceae), commonly known as "arnica-do-campo", is a South American native medicinal plant mainly found in Brazil, Argentina, Uruguay and Paraguay. The indigenous people in these regions use the flowers of this plant to treat diseases of the digestive, musculoskeletal and sensory systems. Many Acmella species are morphologically similar, and there are a few anatomical studies available in the literature that can be used to identify and distinguish them. Several other members of Asteraceae, such as Calea uniflora, Chaptalia nutans, Porophyllum ruderale, Pseudobrickellia brasiliensis and Solidago chilensis, are also called "arnica-do-campo" or "arnica". Applying the same common name to several other species makes it difficult to identify the plant correctly and allows it to be more easily adulterated. The present study characterizes A. bellidioides using microscopy and microchemical techniques to provide pharmacobotanical data to support the authentication of the species. The notable anatomical markers identified in A. bellidioides are hypostomatic leaves, anomocytic stomata, peltate glandular trichomes on the leaf abaxial surface, midrib vascular system with three collateral bundles in an open arch, and the presence of prismatic crystals in the leaves and stems.

ABSTRACT Introduction: Systemic Mastocytosis comprises a group of neoplastic diseases characterized by clonal expansion and infiltration of mast cells into several organs. The diagnosis and treatment of this disease may be challenging for non-specialists. Objective: Make suggestions or recommendations in Systemic Mastocytosis based in a panel of Brazilian specialists. Method and results: An online expert panel with 18 multidisciplinary specialists was convened to propose recommendations on the diagnosis and treatment of Systemic Mastocytosis in Brazil. Recommendations were based on discussions of topics and multiple-choice questions and were graded using the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence Chart. Conclusion: Twenty-two recommendations or suggestions were proposed based on a literature review and graded according to the findings.

RESUMO A utilização de novos produtos, como o biochar e os bioestimulantes, tem potencial para acelerar o crescimento e melhorar a qualidade de mudas que serão levadas ao campo. Assim, o objetivo deste estudo foi avaliar a influência de biocarvão e do bioestimulante vegetal na formação de mudas de Schinus terebinthifolius. O experimento foi instalado em blocos casualizados em esquema fatorial 5 × 2, testando proporções de biocarvão na composição do substrato (0, 7,5, 15, 22,5 e 30%) na presença (15 mL L-1) ou ausência de bioestimulante no tratamento de sementes, com quatro repetições. Foram medidos aos 100 dias após a semeadura: diâmetro de colo, altura, área foliar, comprimento e volume de raiz, massa seca de parte aérea e de raízes. A partir desses parâmetros, foram calculadas relações que determinam a qualidade de mudas. O uso combinado de biochar e bioestimulante influencia na formação e qualidade das mudas de Schinus terebinthifolius, sendo esta associação benéfica para o desenvolvimento radicular das mudas. O biochar mostrou-se viável e pode ser adicionado à mistura de substrato para produção de mudas de S. terebinthifolius. As proporções próximas a 15% de biochar apresentaram melhores resultados de qualidade de mudas. O uso de bioestimulante permite adicionar maiores quantidades de biocarvão a ser misturado no substrato. Plantas mais altas possuem maior diâmetro de caule e comprimento de raiz e plantas com maior volume de raiz proporcionam melhor qualidade de mudas, indicada pelo maior índice de qualidade de Dickson.
ABSTRACT The use of new products, such as biochar and biostimulants, has the potential to accelerate growth and improve the quality of seedlings that will be taken to the field. Therefore, this study aimed to evaluate the influence of biochar and plant biostimulant on the formation of Schinus terebinthifolius seedlings. The experiment was installed in randomized blocks arranged in a 5 × 2 factorial scheme with four replications. Biochar proportions in the substrate composition (0, 7.5, 15, 22.5 and 30%) in the presence (15 mL L-1) or absence of biostimulant in the seed treatment were evaluated. Stem diameter, height, leaf area, root length and volume, and shoot and root dry mass were measured at 100 days after sowing. Relationships were calculated from these parameters, which determine the quality of seedlings. The combined use of biochar and biostimulant influences the formation and quality of Schinus terebinthifolius seedlings, with this association being beneficial for the root development of seedlings. Biochar is viable and may be added to the substrate mixture for producing S. terebinthifolius seedlings. The proportions containing around 15% of biochar presented seedlings with the highest quality. The use of biostimulant allows for adding higher quantities of biochar to be mixed in the substrate. Taller plants have larger stem diameters and root lengths. Plants with larger root volumes provide better seedling quality, evidenced by the higher Dickson quality index.

Various beneficial biological activities have been reported for passion fruit (Passiflora edulis), grown in tropical and subtropical regions. However, no study has yet demonstrated its action against the Zika virus (ZIKV) infection. The present study aimed to investigate the anti-ZIKV of the ethanolic passion fruit seed extract (PFSE), from which, liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis allowed to putatively annotate the occurrence of piceatannol, astringin, scirpusin A, scirpusin B, isookanin-7-O-glucoside and naringenin-7-O-glucoside, two quadranguloside derivatives, tyrosine, and phenylalanine. PFSE is well tolerated by cell lines (Vero E6 and HTR-8/SVneo) and tissue explants from the human placenta. With 1- and 24-h treatments, PFSE consistently reduced the viral load and NS1 protein expression of the two strains of ZIKV (MR766 and PE243) in placental explants and cell lines. Thus, PFSE has a promising potential for developing anti-ZIKV treatments, protecting the placenta against infection caused by ZIKV, along with relevant antioxidant potential, represented by ferric reducing antioxidant power (FRAP) of 390.5 Trolox eq per g dry extract and half maximal inhibitory concentration (IC50) for 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•) of 12.1 µg mL-1, and more than 90% protection from lipid peroxidation. Although further studies need to be conducted, PFSE treatment was safe and effective in trophoblast cells and placental explants, thus representing a promising class of all-accessible products based on the reuse of industrial by-products.
