In this study, we aimed to investigate the anticancer activity of the extract, fractions, and isolated compounds of the flowers of Fridericia platyphylla, and to characterize the bioactive compounds. The chemical diversity of the extracts and fractions was investigated using liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS). We were able to annotate 26 compounds from the classes of flavones, flavonols, flavanones, isoflavones, and cinnamic acid and its derivatives. The dichloromethane fraction showed greater cytotoxicity at a concentration of 100 µg mL−1. In addition, the inhibitory concentrations of the dichloromethane fraction were 22.14 and 30.9 µg mL−1 for MCF-7 and MDA-MB-231 cell lines, respectively, and were capable of inhibiting tumor cell migration. Brachydins A and C were isolated from the dichloromethane fraction and showed the greatest cytotoxicity. The results obtained from this study show the potential biological effect of F. platyphylla flowers as a possible antitumor pharmacological agent. extract LCHRMS. LCHRMS LC HRMS .

We report the electrochemical potential of conductive filaments produced with recycled polylactic acid (rPLA) alongside a mixture of graphite (Gpt) and/or carbon black (CB) and castor oil to create an electrode ready-to-use. Additively-manufactured electrodes (AMEs) were compared with commercial-conductive filament composed of PLA and CB. The Gpt-CB-rPLA and CB-rPLA sensors showed lower charge-transfer resistance (Rct) and a greater heterogenous rate constant, k0, (Rct= 1040 ± 50 Ω and 1810 ± 30 Ω and k0= 6.91 (± 0.58) × 103 and 5.31 (± 0.40) × 103 cm s-1, respectively) compared to the sensor from the commercial filament (Rct = 9620 ± 280 Ω and k0 = 3.62 (± 0.38) ×10-3 cm s-1). The electrochemical response of [Fe(CN6)]3-/4- displayed a peak-to-peak separation of 180 ± 8 mV (Gpt-CB-rPLA) and 240 ± 6 mV (CB-rPLA) compared to commercial AME (740 ±10 mV), without any surface treatment. The filaments were used to create a 2,4,6-trinitrotoluene (TNT) detection platform with linear range of 5-20 and 5-100 µmol L-1 for Gpt-CB-rPLA and CB-rPLA, respectively. The collector-detector device was applied for the analysis of a blast simulation. Finally, it is worth noting that the results obtained are without electrode treatment/activation, indicating that the rough surface of the additively manufactured electrode is an additional feature of the device for collecting explosive residues, simply by rubbing the additively manufactured platform on different surfaces in crime scenarios. rPLA (rPLA Gpt (Gpt andor or CB (CB readytouse. readytouse ready use. use ready-to-use Additivelymanufactured Additively AMEs (AMEs commercialconductive GptCBrPLA CBrPLA chargetransfer charge transfer Rct constant k Rct= 104 5 181 3 691 91 6.9 ( 0.58 058 0 58 10 531 31 5.3 0.40 040 40 s1, s1 s 1, 1 s-1 respectively 962 28 362 62 3.6 0.38 038 38 ×103 ×10 ×10- s1. . s-1) FeCN63/4 FeCN634 FeCN Fe CN6 /4 4 CN [Fe(CN6)]3-/4 peaktopeak peak 18 (Gpt-CB-rPLA 24 (CB-rPLA 740 (74 ±1 mV, , mV) treatment 2,4,6trinitrotoluene 246trinitrotoluene trinitrotoluene 2,4,6 2 TNT (TNT 520 20 5-2 5100 100 5-10 L1 L L- CBrPLA, rPLA, collectordetector collector detector simulation Finally treatmentactivation activation treatment/activation residues scenarios 69 9 6. 0.5 05 53 5. 0.4 04 s- 96 36 3. 0.3 03 ×1 FeCN63 FeCN63/ / [Fe(CN6)]3-/ 74 (7 6trinitrotoluene 246 2,4, 52 5- 510 5-1 0.

RESUMO O objetivo do trabalho foi caracterizar o índice de rendimento, o índice de rendimento de campo, a uniformidade e o ciclo de maturação de quinze genótipos de Coffea canephora cultivados em diferentes ambientes da Amazônia Ocidental. A pesquisa foi conduzida no Amazonas, em Itacoatiara e Manaus, e em Rondônia, em Porto Velho, Brasil. A interação entre genótipos x ambientes foi significativa, indicando que os clones apresentaram desempenho diferenciado entre os ambientes. A superioridade dos coeficientes genotípicos sobre aqueles de natureza ambiental sugere predominância dos efeitos genéticos na expressão dos índices de rendimento e da uniformidade de maturação. O índice de rendimento médio foi de 24,68% e o rendimento de campo de 22,57%, sendo o ambiente Itacoatiara com as maiores médias. A uniformidade de maturação de frutos teve uma média geral de 63,02%, com Porto Velho apresentando a maior uniformidade média (71,78%). A cultivar BRS1216 apresentou o melhor desempenho para os índices de rendimento e proporcionou maior ganho de seleção na média dos ambientes, apresentando adaptabilidade ampla para o índice de rendimento usual e adaptabilidade para ambientes favoráveis ao rendimento de campo.

ABSTRACT This study aimed to characterize the outturn index, field outturn index, uniformity of maturity, and maturation cycle of fifteen Coffea canephora genotypes grown in different environments of the Western Amazon. Conducted in Amazonas (Itacoatiara and Manaus) and Rondônia (Porto Velho), the research evaluated the performance of ten cultivars and five promising genotypes from Embrapa. The genotype × environment interaction was significant, indicating different performance of clones across environments. Genotypic coefficients surpassed environmental ones, indicating a genetic influence on outturn indices and uniformity of maturity. The mean outturn index was 24.68%, and the field outturn index was 22.57%, with Itacoatiara having the highest mean values. The overall mean fruit uniformity of maturity was 63.02%, with Porto Velho achieving the highest mean uniformity value (71.78%). The cultivar BRS1216 exhibited the best performance for outturn indices and provided the highest gain from selection across environments, showing wide adaptability for the outturn index and adaptability to environments favorable for field outturn. Cultivars BRS3210 and BRS3220 achieved more than 82% uniformity of maturity across locations, with BRS3210 adapting to favorable environments and BRS3220 adapting to unfavorable ones. Additionally, BRS3220 had a high mean field outturn index, indicating wide adaptability and high phenotypic stability.

Abstract In Argentina, hemolytic uremic syndrome (HUS) caused by EHEC has the highest incidence in the world. EHEC infection has an endemo-epidemic behavior, causing 20-30% of acute bloody diarrhea syndrome in children under 5 years old. In the period 2016-2020, 272 new cases per year were notified to the National Health Surveillance System. Multiple factors are responsible for HUS incidence in Argentina including person-to-person transmission. In order to detect possible EHEC carriers, we carried out a preliminary study of the frequency of kindergarten teachers with anti-LPS antibodies against the most prevalent EHEC serotypes in Argentina. We analyzed 61 kindergarten teachers from 26 institutions from José C. Paz district, located in the suburban area of Buenos Aires province, Argentina. Fifty-one percent of the plasma samples had antibodies against O157, O145, O121 and O103 LPS: 6.4% of the positive samples had IgM isotype (n=2), 61.3% IgG isotype (n=19) and 32.3% IgM and IgG (n=10). Given that antibodies against LPS antigens are usually short-lived specific IgM detection may indicate a recent infection. In addition, the high percentage of positive samples may indicate a frequent exposure to EHEC strains in the cohort studied, as well as the existence of a large non-symptomatic population of adults carrying pathogenic strains that could contribute to the endemic behavior through person-to-person transmission. The improvement of continuous educational programs in kindergarten institutions could be a mandatory measure to reduce HUS cases not only in Argentina but also globally.

Resumen En Argentina, el síndrome urémico hemolítico causado por Escherichia coli enterohemorrágica (EHEC) tiene la más alta incidencia del mundo. Las infecciones por EHEC tienen un comportamiento endemoepidémico y causan del 20 al 30% de los síndromes de diarrea sanguinolenta en niños menores de 5 años. En el período 2016-2020, se notificaron 272 nuevos casos por año al Sistema de Vigilancia de Salud Nacional. Múltiples factores son responsables de la alta incidencia de SUH en Argentina, incluyendo la transmisión persona-persona. Con el objetivo de detectar posibles portadores asintomáticos de EHEC, realizamos un estudio preliminar de la frecuencia de anticuerpos antilipopolisacáridos contra los serotipos de EHEC más prevalentes en Argentina. El estudio se realizó con muestras de plasma obtenidas de 61 maestras y maestros de jardines de infantes de 26 instituciones del distrito de José C. Paz, localizado en el área suburbana de la provincia de Buenos Aires, Argentina. El 51% de las muestras presentaron anticuerpos contra los serotipos de lipopolisacáridos O157, O145, O121 y O103; el 6,4% de las muestras positivas tuvieron el isotipo IgM (n=2), el 61,3% el isotipo IgG (n=19) y el 32,3% los isotipos IgM e IgG (n=10). Dado que los anticuerpos antilipopolisacáridos presentan usualmente una duración corta, la detección de IgM específica podría indicar una infección reciente. Además, el alto porcentaje de muestras positivas hallado podría indicar una exposición frecuente a las cepas de EHEC en la cohorte estudiada. Asimismo, la gran población de adultos portadores asintomáticos de estas cepas patógenas podría contribuir al comportamiento endémico, a través de la transmisión persona-persona. El perfeccionamiento de programas educacionales continuos en jardines de infantes podría constituir una medida importante para reducir los casos de síndrome urémico hemolítico, no solo en Argentina, sino también en el mundo.

Resumo Introdução: Os cuidados de fim de vida em doentescom doença renal terminal (DRT) podem ser desafiantes e necessitar do apoio de uma equipa especializada em cuidados paliativos (ECP). Objetivo: Caracterizar a população de doentes com DRT encaminhada à ECP e avaliar os determinantes para um fim de vida planeado no domicílio. Métodos: Realizámos um estudo de coorte observacional retrospectivo dos doentes com DRT encaminhados à ECP entre janeiro/2014 e dezembro/2021 (n = 60) e caracterizámos aqueles com DRT previamente conhecida relativamente ao local de fim de vida (n = 53). Resultados: A maioria dos pacientes eram mulheres comidade mediana de 84 anos. Metade dos doentes encontrava-se em tratamento conservador, 43% em hemodiálise crónica e os restantes suspenderam diálise iniciada agudamente. Daqueles com DRT previamente conhecida, 18% morreram em casa. Não foi objetivada associação entre género, idade, cognição, status funcional, comorbilidades, etiologia da DRC ou modalidade de tratamento da DRT e o local de óbito. A anúria e a menor sobrevida após suspensão de diálise associaram-se a um fim de vida no hospital e verificámos uma tendência para o fim de vida em casa nos doentes com mais tempo de acompanhamento pela ECP. Conclusão: O fim de vida no domicílio é possível num programa domiciliário de cuidados paliativos, independentemente de idade, sexo, etiologia da DRC, principais comorbilidades e modalidade de tratamento. A anúria e o menor tempo de sobrevida após suspensão da TRS podem ser fatores limitantes. Um acompanhamento mais longo em cuidados paliativos pode favorecer o fim de vida no domicílio.

Abstract Introduction: End of life care of patients with end-stage kidney disease (ESKD) may be particularly challenging and requires the intervention of a specialized palliative care team (PCT). Objective: To characterize the population of ESKD patients referred to a PCT and evaluate the determinants of planned dying at home. Methods: We performed a retrospective observational cohort study of all patients with ESKD referred to our PCT between January 2014 and December 2021 (n = 60) and further characterized those with previously known ESKD regarding place of death (n = 53). Results: The majority of the patients were female and the median age was 84 years. Half of the patients were on conservative treatment, 43% were on chronic hemodialysis, and the remainder underwent hemodialysis on a trial basis and were subsequently suspended. Of those with previously known ESKD, 18% died at home and neither gender, age, cognition, performance status, comorbidities, CKD etiology, or treatment modality were associated with place of death. Anuria was significantly associated with dying at the hospital as was shorter time from dialysis suspension and death. Although not reaching statistical significance, we found a tendency towards a longer duration of palliative care follow-up in those dying at home. Conclusion: Dying at home is possible in a palliative domiciliary program regardless of age, gender, etiology of CKD, major comorbidities, and treatment modality. Anuria and shorter survival from RRT withdrawal may be limiting factors for planned dying at home. A longer follow-up by palliative care may favor dying at home.

RESUMO Os resíduos da mineração de vermiculita, embora de baixa solubilidade, contêm nutrientes como cálcio, magnésio e potássio em concentrações que permitem seu uso agrícola. Bactérias benéficas podem aumentar a solubilidade deste resíduo e sua eficiência. Objetivou-se avaliar a influência da bioinoculação do resíduo de vermiculita, associado ao esterco bovino, na liberação de nutrientes e no crescimento inicial do milho. Foi realizado delineamento inteiramente casualizado em casa de vegetação com sete tratamentos e quatro repetições. Os tratamentos foram: T1 - solo sem adubação; T2 - solo adubado com fontes solúveis de nutrientes (fertilização convencional); T3 - aplicação de resíduo de vermiculita (VR); T4 - VR enriquecido com esterco bovino (CM); T5 -VR+CM com Bacillus subtilis; T6 - VR + CM + B. amyloliquefaciens e T7 - VR + CM + B. subtilis + B. amyloliquefaciens). O VR aumentou a disponibilidade de Ca e K no solo, porém seu desempenho foi inferior às fontes solúveis. Independentemente da utilização de esterco bovino ou de microrganismos benéficos, os resíduos da mineração de vermiculita aumentaram a disponibilidade de Ca e K no solo, mas não foram capazes de igualar as fontes solúveis de nutrientes. Os resíduos de mineração associados ao esterco bovino e aos microrganismos benéficos (B. subtilis e B. amyloliquefaciens) aumentaram a atividade microbiana e aumentaram a liberação de cálcio disponível para o milho.

ABSTRACT Vermiculite mining residues, although of low solubility, contain nutrients such as calcium, magnesium, and potassium at concentrations that allow their agricultural use. Beneficial bacteria can increase the solubility of this waste and its efficiency. The objective of the present study was to evaluate the influence of bio-inoculation of vermiculite residue, associated with cattle manure, on the release of nutrients and initial growth of maize. A completely randomized design was performed in a greenhouse with seven treatments and four replications. The treatments were: T1 - soil without fertilization; T2 - soil fertilized with soluble sources of nutrients (conventional fertilization); T3 - application of vermiculite residue (VR); T4 - VR enriched with cattle manure (CM); T5 - VR + CM with Bacillus subtilis; T6 - VR + CM + B. amyloliquefaciens, and T7 - VR + CM +B. subtilis + B. amyloliquefaciens). Regardless of the use of cattle manure or beneficial microorganisms, vermiculite mining waste increased the availability of Ca and K in the soil, but was not able to match the soluble sources of nutrients. Mining waste associated with cattle manure and beneficial microorganisms (B. subtilis and B. amyloliquefaciens) increased microbial activity and enhanced the release of available calcium for maize. VR increased the growth and the dry mass production of maize compared to the non-fertilized soil, but was consistently inferior to conventional fertilizer. residues magnesium efficiency bioinoculation bio inoculation replications were T fertilization fertilization) (VR) (CM) B amyloliquefaciens +B amyloliquefaciens. .

Resumo As comunidades quilombolas, estão presentes em diversos estados brasileiros, vivendo em condições de saúde mais precárias. Isto ocorre por conta do isolamento geográfico, das limitações de acesso e da falta de qualidade no serviço quando este é prestado. Nesse sentido, o objetivo do estudo foi analisar a qualidade de vida de mulheres de uma comunidade quilombola do nordeste brasileiro. Estudo observacional, transversal e descritivo. Foram entrevistadas 160 mulheres adultas, através de um formulário para a coleta de perfil e do questionário de Qualidade de Vida WHOQOL – bref. Foi observado que as mulheres tinham em média 40,7 anos (±17,25), casadas, autodeclaradas negras, com fundamental incompleto, do lar, sem renda, com moradia de alvenaria, própria, com até 6 cômodos, abastecidas por caixa de água comunitária, tratada. A Qualidade de Vida, apresentou escores medianos nos domínios: físico (3,18), psicológico (3,4), relações sociais (3,45) e meio ambiente (2,59). Com a realização desta pesquisa foi possível caracterizar a comunidade quilombola de Santa Luzia do Norte-AL quanto as dificuldades de acesso a saúde e geração de renda, fatos que repercutem na sua condição de saúde. Os problemas descritos neste estudo podem contribuir para que ações de saúde sejam planejadas e efetivadas com o intuito de melhorar as condições socioeconômicas e de saúde nessa comunidade, considerando-se o contexto social, político e ambiental, valorizando seus saberes e práticas tradicionais.

Abstract Quilombola communities are present in many Brazilian states living in precarious health conditions. This is due to geographic isolation, limitations to the access of the area in which they live in, and the lack of quality in the service when it is needed to be provided. Therefore, the aim of this study was to analyze the quality of life of women from a quilombola community in northeastern Brazil. It is an observational, cross-sectional and descriptive study. 160 adult women were first interviewed through a form to collect a profile and then it was applied the WHOQOL Quality of Life questionnaire – bref. It was observed that the women were on average 40.7 years old (±17.25), married, self-declared black, who did not finish elementary school, housewife, had no income, with their own masonry house, with up to 6 rooms, supplied by a box of community treated water. Quality of Life had median scores in the domains: physical (3.18), psychological (3.4), social relationships (3.45) and environment (2.59). With this research, it was possible to characterize the quilombola community of Santa Luzia do Norte-AL regarding the difficulties of access to health and income generation, issues that affect their health condition. The problems described in this study can contribute to health actions being planned and carried out in order to improve socioeconomic and health conditions in this community, considering the social, political and environmental context, valuing their traditional knowledge and practices.

Resumo O ácido valproico associado ao valproato de sódio (VPA) é um importante agente anticonvulsivo usado há décadas no tratamento de distúrbios neurológicos. Também atua como um modulador epigenético ao inibir as desacetilases de histonas, permitindo a acetilaçao de histonas, afetando o estado de metilação do DNA e das histonas e a expressão gênica, e induzindo a remodelação da cromatina. Os insetos representam um importante modelo animal para estudos em diversas áreas da ciência e dada a sua alta plasticidade fenotípica os torna modelos alternativos para estudos epigenéticos e de resposta a agentes moduladores epigenéticos. Esta breve revisão enfatiza relatos recentes sobre epigenética em insetos e a contribuição de estudos sobre a ação do VPA nesse grupo animal, incluindo efeitos sobre marcadores epigenéticos, estendendo a compreensão farmacológica do potencial desta droga e demonstrando a utilidade dos insetos como um modelo animal alternativo para estudos de drogas.

Abstract Valproic acid in association with sodium valproate (VPA) is an important anticonvulsant drug used for decades to treat neurological disorders. VPA also acts as an epigenetic modulator by inhibiting histone deacetylases, permitting histone acetylation, affecting the DNA and histone methylation status and gene expression, and inducing chromatin remodeling. Insects represent an important animal model for studies in several areas of science. Their high phenotypic plasticity makes them alternative models for epigenetic studies. This brief review emphasizes recent reports on insect epigenetics and the contribution of studies on the VPA action in insects, including effects on epigenetic markers, extending the pharmacological understanding of the potential of this drug, and demonstrating the usefulness of insects as an alternative animal model to drug studies.

Resumo A leishmaniose visceral é uma doença tropical negligenciada. Foram avaliadas a distribuição espacial dos casos de leishmaniose visceral no estado de Alagoas. Todos os casos de LV, registrados pela secretaria de saúde, foram analisados e georreferenciados. Entre 2008 e 2017, 97,1% dos municípios apresentaram classificação esporádica de transmissão. Com a evolução temporal, a incidência de casos de leishmaniose visceral se concentrou na maioria dos municípios da microrregião de Santana do Ipanema-AL. A análise espaço-tempo, se considerada, pode promover o aprimoramento das ações de vigilância e controle da leishmaniose visceral.

Abstract Visceral leishmaniosis is a neglected tropical disease. We evaluated the spatial distribution of cases of visceral leishmaniosis in the state of Alagoas, Brazil. All cases of VL, registered by the health department, were analyzed and georeferenced. Results: Between 2008 and 2017, 97.1% of the municipalities presented sporadic classification of transmission. With temporal evolution, the incidence of cases of visceral leishmaniosis was concentrated in most municipalities in the microregion of Santana do Ipanema-AL. Space-time analysis, if considered, may promote the improvement of surveillance and control actions of visceral leishmaniosis.

A retrospective study was conducted in a public hospital in Maceió-AL, by collecting data of all medical records with positive blood cultures. Out of the 2,107 blood cultures performed, 17% were positive with Staphylococcus coagulase negative (51.14%), followed by Staphylococcus aureus (11.21%) and Klebsiella pneumoniae (6.32%). Gram-positive bacteria predominated among positive blood cultures, highlighting the group of Staphylococcus coagulase-negative. While Gram-negative bacteria had a higher number of species among positive blood cultures.
