Authors: Lima Natália Peixoto , Motta Janaína Vieira dos Santos , Horta Bernardo Lessa
Published: February 2025

Using data from a birth cohort study, we evaluated the long-term association between breastfeeding and metabolic cardiovascular risk factors at 30 years old. In 1982, the 5,914 live births in maternity hospitals in Pelotas, Rio Grande do Sul State, Brazil, were examined and the mothers were interviewed. Since then, these participants have been prospectively followed. The cohort members were interviewed at 30 years old and information on blood pressure, carotid intima-media thickness, pulse wave velocity, random blood glucose, and blood lipids were obtained. Simple and multiple linear regressions were used. In the crude and adjusted analyses, duration of breastfeeding did not show any clear association with mean arterial pressure, carotid intima-media thickness, and pulse wave velocity. Likewise, total and non-HDL cholesterol and blood glucose were not related to infant feeding. Regarding HDL cholesterol, it was positively related to predominant breastfeeding duration in the crude analysis, but the association disappeared after controlling for confounding variables. Concisely, our findings suggest that there is no association between duration of breastfeeding and cardiometabolic risk factors in adulthood. Despite that, promotion and support of breastfeeding must be reinforced due to its well-known benefits, such as reduction of infant and child mortality and human capital development.

Published: February 2025

This study aimed to analyze the cost-effectiveness of three tuberculosis (TB) antigen-based skin tests (TBST) (Diaskintest, C-TST, and Cy-TB) and QFT-Plus for TB infection diagnosis compared to the current standard of care, PPD Rt-23 tuberculin skin test (TST), among healthcare workers in Brazil. A state-transition Markov model was employed, simulating a cohort of healthcare workers (five annual cycles) for testing and treating TB infection with three months of weekly doses of rifapentine and isoniazid (3HP) under the Brazilian public health system perspective. Effects (TB disease averted) and costs for screening and treating TB infection were discounted at 5%. Incremental cost-effectiveness per TB averted was estimated. One-way and probabilistic sensitivity analysis were performed. Brazil, an upper-middle-income country with a high burden of TB, shows one of the largest universal public health systems and provides free-of-charge diagnosis and treatment for TB and TB infection. TST is the standard of care, whereas QFT-Plus is available for very high-risk populations. The three new TBST are under validation for eventual incorporation. Patients or participants: a hypothetical cohort of 10,000 healthcare workers, working at any level of healthcare service, and negative TST results in the previous year of both sexes with a baseline negative TST result. Diaskintest, C-TST, Cy-TB, and QFT-Plus were found to show a higher specificity. Costs with QFT-Plus were higher due to equipment, human labor, and test price. Diaskintest was the most cost-saving strategy, followed by Cy-TB for TB preventive treatment with 3HP. In the Brazilian scenario, Diaskintest and Cy-TB are the most cost-effective tests for sequential testing of healthcare workers.

ABSTRACT: Inspired by the possibility of further understanding the role of pectineus muscle in the pathophysiology of hip dysplasia, this study evaluated the correlation between the Norberg angle, weight, sex, and age with the acoustic radiation force impulse (ARFI) elastographic findings of the pectineus muscle in dysplastic dogs through a quantitative analysis using shear wave velocity. Thirty-one dogs that had been radiographically diagnosed with hip dysplasia were selected, with a mean weight of 32.9 ± 8.8kg and age of 4.3 ± 1.5 years. The dogs were submitted to mode B ultrasonography and ARFI elastography of the pectineus muscles, bilaterally. The mean value of the shear wave velocity was 3.5 ± 1.0m/s, which showed a positive correlation with the degree of hip dysplasia (P = 0.0065; r = 0.34) and with age (P = 0.0197; r = 0.30). There was a negative correlation with the Norberg angle (P = 0.0197; r = 0.30), and there was no relation with body weight (P = 0.7435; r = 0.04). It was higher (P = 0.0050) in females (3.9 ± 1.1 m/s) compared to males (3.2 ± 0.8m/s). The variable age contributed to the stiffness of the pectineus muscle in dysplastic dogs. The pectineus muscle was significantly stiffer in females than in males. Weight did not show any association with pectineus muscle stiffness, based on the ARFI elastography findings. The ARFI elastography exam has shown to be feasible in identifying changes in the pectineus muscle of dogs, which could be correlated with the studied variables.

ABSTRACT: The sperm recovered from the epididymal lack seminal plasma (SP), and the contribution that it makes of ions, lipids, energy substrates, proteins and other organic compounds. This research aimed evaluated the effect of SP on the oxidative status and quality of freeze-thawed epididymal bovine sperm. SP from 10 bulls was collected and pooled. Epididymal tail sperm was recovered from 16 testis-epididymal complexes. Each sample was distributed in four treatments for sperm freezing: 0% SP (control), 10% SP (SP10), 20% SP (SP20) and 30% SP (SP30). The SP’s total antioxidant capacity (TAC) was measured using the discoloration test with ABTS●+ cation radical (ABTS) and oxygen radical absorption capacity (ORAC) assays. In post-thawed semen, motility and sperm kinetics were evaluated using the Sperm Class analyzer system (SCA®) system, the functional integrity of the membrane using the hypoosmotic test (HOST), sperm vitality (SV) and abnormal morphology (AM) using eosin-nigrosin staining. Lipid peroxidation (LP), mitochondrial membrane potential (ΔΨM) and reactive oxygen species (ROS) were evaluated by spectrofluorimetry. The TAC contribution of the freezing extender was 490.2 μmol Trolox Eq/L (ABTS) and 120.5 μmol Trolox Eq/L (ORAC) for each 10% of supplemented SP. SP10 improved progressive motility (PM) but increased AM. SP20 had a higher PM, average path velocity (VAP) and linear velocity (VSL) but reduced SV. SP30 increased VSL but scored lower in the HOST than SP10 (P < 0.05). All SP treatments increased ROS and LP. In conclusion, the addition of SP contributed to the antioxidant capacity of the freezing extender and can improve the motility and kinetics of bovine epididymal spermatozoa. However, it can increase oxidative stress and alter sperm morphology and membrane integrity.
Development of sustainable polymeric membranes produced with green solvents

Published: February 2025

Abstract Polymeric membrane separation technologies have gained widespread prominence in many applications, including water and wastewater treatment to remove contaminants of emerging concern (CEC). These technologies can be recognized as sustainable separation techniques due to their scalable potential and low energy consumption. However, the membranes are usually prepared with organic solvents such as N-methyl-2-pyrrolidone (NMP) and dimethylacetamide (DMAc), which are toxic and harmful to the environment and human health. Furthermore, these solvents are being banned in some countries and included on lists of substances of high concern. Therefore, finding environmentally sustainable solvents (green solvents) to produce “green membranes” has been a matter of great interest. The objective of the present study is the development of porous membranes, prepared with green solvents, Cyrene (Cyr) and γ-Valerolactone (GVL). The membranes were prepared by the phase inversion technique using Polysulfone (PSF), Polyvinylpyrrolidone (PVP) and Cyr or GVL or a mixture of both solvents. In this work, it was possible to produce membranes with both green solvents, as well as using a mixture of them. The membranes were characterized and tested for removing a CEC (Rosuvastatin) from water. Rosuvastatin rejection of 80% was achieved for membranes produced with a mixture of green solvents Cyr and GVL. These results are promising, as they make the membrane production process more sustainable as recommended by the 2030 Agenda through the 17 SDGs.

Published: February 2025

Abstract New processing routes and alternatives have been studied in the manufacture of automotive parts aiming for lower energy consumption and less environmental impact. In this context, continuous cooling bainitic steels have emerged to address this demand by eliminating the quenching and tempering treatments. In substitution to heat treatments to improve wear resistance on the surface, plasma nitriding is a candidate. However, the effects on the core of bainitic microstructures over long time processes at subcritical temperatures are limited and should be further investigated. Especially in case of unexpected effects on the core of steels depending on time and temperature, compromising performance in service. The aim of the present study was to evaluate the effects of two plasma nitriding conditions at 500 ºC on the core of DIN 18MnCrSiMo6-4 continuous cooling bainitic steel, for 20 h and 30 h of treatment. For this purpose, characterization techniques, such as optical microscopy and SEM were applied to evaluate microstructural changes on the core followed by the Vickers hardness test to estimate possible softening effects. The research found a decrease of austenite fraction in the nitride conditions in comparison to the initial microstructure of the bainitic steel, a reduction of dislocation density of ferrite measured by Williamson–Smallman relation and the hardness dropped about 10% after 20 h and 20% after 30 h of treatment. The conclusion pointed out alteration on the core for the plasma nitriding treatments for long time cycles at a temperature of 500 °C, similarly to effects observed in tempering treatments.

ABSTRACT The production of high-quality wheat seeds in soils with low soil organic matter (SOM) content requires the use of nitrogen (N) fertilization techniques, since different types of N fertilizers have different impacts on crop uptake and development. The present study aimed to evaluate the quality of wheat seeds from modern cultivars, grown in soils with low SOM content, under different ammoniacal and nitric N fertilization rates in Southern Brazil. Seeds were produced in three locations (Capão do Leão, Pelotas and Rio Grande, RS, Brazil), during two crop seasons (2021/22 and 2022/23), under N rates of 0, 40, 80, 120, and 160 kg·ha-1 of N, supplied with urea (46% N) and ammonium nitrate (AN) (27% N). Germination test, dry weight and length of aerial part and root of seedlings, accelerated aging test (AAT), emergence in seedbed, and electrical conductivity (EC) of seeds were evaluated. It was observed that seed germination presented acceptable values, with rates of viable seeds varying from 86 to 99%, except location 3, which presented values below 80% germination at the rate of 160 kg·ha-1 of N. A reduction in seed vigor was observed with the use of AN. Increasing N rates reduced germination in AAT and increased seed EC. EC has a negative correlation with all parameters indicating good physiological seed quality. It was concluded that excessive rates of N negatively impact the physiological potential of wheat seeds grown in soils with low SOM contents.
Movimentos kaingang na paisagem: casas, aldeias, aglomerados político-cerimoniais interaldeães e suas consequências para as relações com o exterior
Authors: Aquino Alexandre Magno de
Published: February 2025

Resumo A aldeia kaingang replica, em suas transformações históricas, a cosmologia, a organização social e política, residindo aí a própria fundação da socialidade. A etnografia demonstra que a casa conecta a esfera doméstica e a esfera pública, daí sua centralidade na configuração socioespacial, dos grupos locais aos aglomerados político-cerimoniais interaldeães, mas também na relação com os brancos. A narrativa mítica da construção da casa primeva evidencia uma tensão implícita, como consequência das incorporações de poderes exteriores, ora pela onça, ora pelo veado e, depois, pelo macaco, contrastando com a importância das mediações realizadas pelas metades exogâmicas kamë e kanhrukrë e pela perspectiva xamânica na vida social. Em diversos contextos históricos, verifica-se que essas relações, diametrais e concêntricas, envolvem a casa, o espaço limpo e a floresta, traduzindo as transformações na paisagem, como o incremento da infraestrutura da aldeia (igrejas, postos de saúde, escolas), seja nas Terras Indígenas demarcadas, seja nas “retomadas”.

Authors: Sridhar M. Melwin Jagadeesh , Ravichandran M. , Veerappan G.
Published: February 2025

Hybrid metal matrix composites (MMCs) have a higher potential for widespread use in structural engineering and functional device applications because they show better overall mechanical and functional response than their conventional equivalents. Silicon Carbide (SiC) and Yttrium Oxide (Y2O3) reinforced Copper hybrid composites were produced by powder metallurgy (PM) process sequence. Both the reinforcements were included in the wt. % of 2.5, 5.0 and 7.5. The homogeneous presence of SiC and Y2O3 particles in copper MMC’s was confirmed by morphology and characterization studies. The blended milled powders were produced in the form of cylindrical billets using a punch and die arrangement, by cold compaction method at 400 MPa pressure, in a hydraulic press. Sintering was carried out at 900°C for 5 hours in a Box furnace. The inclusion of SiC and Y2O3 in the copper matrix composites improved the density, hardness, compressive strength (CS), wear resistance and decreased the corrosion rate (CR).Pin on disc (POD) experiments was conducted to study the wear behavior of the composite samples. The minimum wear rate (WR) 3.31049 x 10-4 mm3/m was obtained for the composite contain 7.5 wt. % of SiC and 7.5 wt. % of Y2O3.

ABSTRACT Background: The prevalence rates of exclusive and non-exclusive breastfeeding worldwide remain well below levels recommended as desirable by the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF). Unquestionably, this scenario results in negative consequences for women, children and communities. Since inadequate training of healthcare professionals to manage the difficulties faced by breastfeeding mothers has been highlighted as one of the factors linked to this issue, training strategies that include innovative inter-professional tools may help tackle this problem. Such tools should appeal to the current generation of undergraduate students in healthcare-related courses, a population group well adept in the use of digital technology. Objective: The primary aim of this study was to create and validate an inter-professional, educational quiz on breastfeeding designed for students in healthcare-related fields, with a view towards improving breastfeeding rates in northeastern Brazil. Methods: A self-study quiz intended to increase knowledge on breastfeeding was created within a remote education module using the Analysis, Design, Development, Implementation and Evaluation (ADDIE) model. The quiz was developed by a group of specialists in information technology (IT), while a panel of experts from the Pan American Health Organization and the Faculdade Pernambucana de Saúde validated its content and the distance learning techniques. The internal review board of the Faculdade Pernambucana de Saúde approved the study protocol (CAAE: 62652122.8.0000.5569). Results: An inter-professional educational quiz on breastfeeding for students in health-related fields was constructed to stimulate their acquisition of basic knowledge on breastfeeding and as a means of providing information to the public. Conclusion: The rules of the validated quiz, baptized “The Milky Way”, are easily understood and its implementation will contribute significantly to the training of future healthcare professionals with respect to breastfeeding.

Authors: Florêncio Marília Carolina Paiva , Borges Laís Rêgo , Nogueira Maria Clara Alves , Moreira Deborah Pedrosa , Bastos Raimundo José Arruda
Published: February 2025

RESUMO Introdução: As artes são capazes de estimular os alunos a usarem a própria imaginação, o que proporciona o desenvolvimento de novas perspectivas e o pensamento crítico e criativo, importantes na resolução de problemas no exercício profissional. Para além da obtenção de conhecimento técnico, as artes favorecem uma postura ética e profissional, pautada na escuta, na sensibilidade, na empatia e no compromisso. Uma boa relação médico-paciente deve-se a um profundo humanismo do profissional, resultando em uma melhor coleta da história clínica e levando-o a realizar manejos mais assertivos, eficazes e racionais. Objetivo: Este estudo teve como objetivo avaliar o envolvimento e o interesse artístico e literário dos estudantes de Medicina de uma instituição de ensino superior e a opinião deles sobre a importância desse envolvimento durante a graduação para a formação humana e o desenvolvimento de habilidades médicas. Método: Trata-se de um estudo do tipo descritivo transversal, realizado no segundo semestre de 2022, na cidade de Fortaleza, capital do Ceará, por meio de um questionário elaborado especificamente para esse fim. O trabalho segue os aspectos éticos com o CAAE nº 38707720.0.0000.5049. Resultado: Dentre os 200 participantes da pesquisa, 92,5% acreditam que arte e literatura são importantes na formação médica. Entretanto, apenas 38,5% demonstraram interesse em participar de grupo extracurricular que aborde o estudo das artes. Observou-se que aproximadamente 60% dos estudantes que desenvolviam alguma atividade artística a interromperam em decorrência do início do curso. Além disso, 56,5% acreditam que cursar Medicina os impossibilita de se envolver em atividades artísticas e literárias devido à falta de tempo ou de disposição em decorrência da rotina imposta pela graduação médica. Conclusão: Apesar de uma considerável parte dos estudantes de Medicina concordar com a importância das artes e da literatura na formação médica, muitos ainda não estão dispostos a experienciar isso durante o processo de aprendizagem, sendo essencial um maior incentivo desse envolvimento, tendo em vista a importância das artes e da literatura na formação humana do médico.

Published: February 2025

Resumo O objetivo do artigo é realizar uma análise histórica sobre a atuação da Rede Federal na oferta de cursos técnicos em saúde, entre os anos 2017 e 2023, com base em dados obtidos na Plataforma Nilo Peçanha do Ministério da Educação. Parte-se da problematização inerente aos baixos indicadores de participação do setor público na formação de técnicos em saúde, da curricularização da saúde por meio da pedagogia das competências e dos avanços das políticas neoliberais que alteram as relações de formação humana e profissional. O artigo orientou-se pelo aporte teórico e metodológico da matriz do materialismo histórico e dialético, ao depreender que a relação trabalho, educação e saúde constitui-se como uma determinação da realidade social. Os resultados corroboraram a baixa participação da Rede Federal na oferta de cursos técnicos e de matrículas em saúde e a intensa representatividade da iniciativa privada. Entretanto, revelaram um importante dado que endossa o papel político e social da Rede Federal e, principalmente, dos Institutos Federais: o aumento contínuo no número de matrículas no ensino médio integrado em saúde.
Contribuições para uma Análise Psicopolítica do Populismo

Published: February 2025

Resumo: O objetivo do artigo é discorrer sobre três debates propostos na teoria democrática radical e plural que permitem interpelar modos de compreensão da dinâmica política das sociedades ocidentais contemporâneas: a crítica ao marxismo, a crítica à democracia deliberativa e a crítica ao rechaço elitista à noção de populismo. Por meio desses debates, focalizando a compreensão sobre o sujeito político, abordaremos contribuições dessa teoria para a discussão do fenômeno do populismo no campo da psicologia política. Concebemos que o problema da democracia e da construção do povo é um tema antigo no pensamento político, mas tem sido retomado de maneira central em razão, sobretudo, da emergência de populismos de direita no século XXI. A teoria democrática radical e plural contribui para a compreensão do populismo em termos psicopolíticos e, assim, para a discussão desse fenômeno na psicologia política ao concebê-lo de maneira formal e se distanciar da dicotomia entre subjetividade e objetividade, entre paixão e racionalidade, entre sujeito e estrutura.

Resumo: A Teoria Life-Span/Life Space (LSA) foi desenvolvida a partir da suposição de que assumimos diferentes papéis ao longo do ciclo vital, fundamentais para o desenvolvimento da identidade vocacional. A maturidade para a escolha profissional é um dos processos identificados no desenvolvimento de carreira. No entanto, tomar decisões sobre a carreira constitui uma tarefa complexa ao lidar com muitas dúvidas. Por este motivo, o aconselhamento de carreira (AC) pode auxiliar jovens e adultos no planejamento da vida profissional. Deste modo, esta pesquisa objetivou verificar o efeito do AC sobre a maturidade para escolha vocacional em estudantes do terceiro ano do ensino médio (N = 130) de escolas públicas e particulares. Os participantes eram predominantemente do sexo feminino (70%), com idades entre 16 e 18 anos (M = 17,13; DP = 0,589). Tratou-se de uma pesquisa com desenho pré e pós-intervenção nas modalidades individual ou em grupo. Foram utilizados a Escala de Maturidade para Escolha Profissional (EMEP) e um questionário de percepção sobre as intervenções. Os dados foram tratados por meio de análises descritivas, comparação entre grupos, correlação e regressão. Os resultados evidenciaram a diminuição do efeito das variáveis sociodemográficas sobre a maturidade após a intervenção, além de mudanças significativas (p < 0,001) produzidas na maturidade (d = 0,56) e em suas dimensões (d = 0,55; 0,39; 0,36; 0,31 e 0,23 respectivamente para determinação, conhecimento da realidade, autoconhecimento, responsabilidade e independência). Pesquisas na área devem prosseguir considerando estudantes de outras séries do ensino médio ou períodos do desenvolvimento como adultos.

Abstract Porcine breeding industries typically ensure the viability of boar artificial insemination doses during a 5-day liquid storage period at 17 °C. This study aimed to investigate whether the addition of L-carnitine (LC) to boar semen doses on different days of cooled storage could extend their usability. In experiment 1, LC was added to porcine semen doses on the fifth day (d5) of cooled storage performing five treatments control (no LC), 0.5, 1-, 5- and 10-mM LC. On d6 and d8 of storage, semen samples were evaluated for sperm motility and kinematic parameters, membrane functionality, and hydrogen peroxide and nitrite concentrations. In experiment 2, the number of sperm bound to the zona pellucida (ZP) was determined, as a way to investigate sperm penetration capability from boar insemination doses, with co-incubation with porcine oocytes. LC concentration that produced the most favorable outcomes in Experiment 1 was chosen to experiments 2 and 3, performing two treatments in the absence and with the LC. In Experiment 3, LC was added to cooled porcine semen doses after one day of storage (d1), and the same evaluations of experiment 1 were conducted on days 5, 7, 9, and 12, including sperm membrane integrity. The addition of 10 mM LC on d5 and d1 of storage improved sperm motility, which was extended up to 8 and 12 days of cooled storage, respectively. LC addition on d5 of storage increased sperm membrane functionality, while when added to semen on d1 of storage, it decreased NO2- concentration on d9. On d6 of cooled storage 10 mM LC increased the number of sperm bound to ZP compared to the control. In conclusion, adding 10 mM LC to porcine semen doses at 17 °C improved sperm characteristics and ZP binding, ultimately enhancing sperm viability for up to 12d.

Abstract Owing to the low heritability of reproductive traits, the search for markers and their interrelationship that could indicate reproductively superior individuals is important in the selection process for bovine reproductive efficiency. This study aimed to investigate the possible interrelationships between the antral follicle count (AFC), vulvar-width (VW), anti-Müllerian hormone (AMH) concentrations, fertility in Bos Taurus and Bos Indicus females. Brahman (Bos Taurus-Indicus, n = 126) and Simmental and Angus (Bos Taurus-Taurus, n = 155) cows were classified as having large (≥86 mm) and small (<86 mm) VW. From each group, one blood sample per animal was collected to determine the AMH serum concentrations. The GLIMMIX procedure in SAS® was used to determine whether vulva width (VW) and AMH classes, associated or not with breed, could influence the age at first calving (FCA), calving to first service interval (CFSI), calving interval (CI), number of services per pregnancy (SP), and number of viable oocytes (VO). Antral follicle count (AFC) (36.10 ± 1.90 vs. 22.78 ± 1.64, for large and small VW, respectively), AMH (1.17 ± 0.07 vs. 0.48 ± 0.007 ng/mL), and viable oocytes or VO (18.86 ± 1.76 vs. 10.15 ± 1.49) were greater (P < 0.05) in the large VW than in the small VW. Brahman cows had greater AFC (36.30 ± 1.34 vs. 22.09 ± 1.67), VW (106.94 ± 15.83 vs. 69.78 ± 14.11 mm), and AMH (1.18 ± 0.07 vs. 0.42 ± 0.05 ng/mL) compared to that of taurine cows. In conclusion, VW was an efficient predictor of AFC and AMH concentrations in both genetic groups, but under the conditions of this trial no link could be detected between these variables and the reproductive indices studied.

Abstract The objective of this study was to investigate the effects of GnRH at insemination on pregnancy and lambing in seven ewe populations during the breeding season. Estrus was synchronized in 1560 adult ewes using an intravaginal sponge impregnated with flurogestone acetate. The sponge was left in the vagina for 12 days followed by an injection of 330 IU of eCG at sponge removal. Each ewe was inseminated twice at 48 h and 60 h after sponge removal. The treatment group was intramuscularly injected at the first insemination with a dose of 16 μg GnRH and the control group with saline solution in each ewe population. The results showed that GnRH administration significantly decreased the pregnancy rate in three ewe populations, but had no effects in four ewe populations. Additionally, the litter size tended to increase in the treatment group compared to the control group in all seven ewe populations, but the difference was not significant. In conclusion, GnRH administration at insemination was not recommended for ewes undergoing a timed artificial insemination during the breeding season. The breed/population may be a critical determinant of the potential for exploiting GnRH application in sheep breeding programs.
Leaf traits and herbivory in a resin-producing plant species growing in floodable and non-floodable areas of the pre-Amazonian white-sand forest

Abstract Plant species in the white-sandy forests are subject to unstable soils, high salinity, luminosity, extreme temperatures, and flooding caused by tidal cycles. Protium heptaphyllum, a tree species in the Burseraceae family known for its resin production, occurs in both floodable and non-floodable areas. We investigated differences in the accumulated herbivory indexes in leaves during the leaflet lifespan and correlated these data with leaf morphoanatomical traits in plants from floodable and non-floodable areas. Samples of young and mature leaves were processed using standard plant anatomy techniques. The percentage of leaf area consumed by herbivores and quantitative morphoanatomical data were subjected to MANOVA and ANOVA. Herbivory indexes of young and mature leaves were similar between plants from floodable and non-floodable areas. The morphoanatomical features of young leaves were also similar in plants from both areas. However, mature leaves from individuals in the floodable area exhibited longer leaflets and a higher abundance of wider secretory canals compared to plants from the non-floodable area. We suggest that most leaf consumption by herbivores occurs during the early stages of leaf development when there are fewer chemical defenses, and the leaflets are more tender.

Abstract Anatomical studies of the leaf blade have been used to complement the morphological data and aid circumscription and identification in Arecaceae. The hybrid palm ×Butyagrus nabonnandii results from the natural cross between Butia odorata and Syagrus romanzoffiana. This study aimed to verify if the leaf anatomy can help identify the hybrid and differentiate it from the parental taxa. Samples from the middle portion of the pinnae were collected and subjected to the usual techniques for light microscopy. Three portions of the pinnae were sampled: margin, intermediate region, and midrib. The main characteristics considered were the arrangement of fibre and vascular bundles. Pinnae anatomy proved to be useful in the identification of ×B. nabonnandii, because it showed a distinctive pattern, highlighting the importance of leaf anatomy in differentiating the hybrid from parental taxa. The pinnae anatomy of the hybrid was a combination of parental taxa’s characters, similar to the external morphology.
Seedling production of bromeliad endemic to the semiarid region of Bahia, Brazil

Published: February 2025

Abstract Bromeliads are plants that, in addition to marked ecological importance, have increasing ornamental potential in the flower market, being commonly collected in an extractive way, which results in genetic loss of the exploited species, putting them in different degrees of threat. Culture of plant tissues has been shown to be a viable alternative for the propagation of many bromeliads. The aim of this study was to produce seedlings of Neoregelia mucugensis by micropropagation. In vitro multiplication of sprouts via direct organogenesis was obtained in static liquid medium containing 6-benzylaminopurine (BAP) cytokinin. The sprouts were rooted in activated charcoal medium and transferred to the ex vitro condition, and 100% plant survival was obtained. It is concluded, therefore, that the production of seedlings of N. mucugensis is viable by micropropagation.
Sound Dramaturgies: repoliticizing performance
Authors: Poulou Angeliki , Manousakis Manolis
Published: February 2025

ABSTRACT Sound Dramaturgies: repoliticizing performance – The paper explores the potential of sound to repoliticize theatre and performance. By examining the activity and dramaturgical practices of the multimedia art collective Medea Electronique (Greece), it highlights contradictions of contemporary art, particularly the continuous transition from ‘everything is political’ to ‘no, not everything is political’ and vice versa. From a post-Brechtian perspective, the political function of art lies in preserving the diverse sensibilities at the core of art’s autonomy. This entails avoiding that art be reduced to a post-political gesture or aligning it too closely with everyday aestheticized experiences.
“Pateada”: echoes of an extinct but noisy practice
Authors: Souza Luiz Paulo Pimentel de
Published: February 2025

ABSTRACT “Pateada”: echoes of an extinct but noisy practice – Historically, the theater spectator has been constituted as a central figure in both theatrical practice and theory, becoming the target of an artistic-pedagogical discourse. Starting from this premise, this article aims to problematize the game play between conduct and counter-conduct in which the theater spectator was entangled. To do so, we propose to observe an extinct practice in Brazilian theaters but prevalent throughout the 19th century – the “pateada” – which involved a noisy stomping of feet by the audience with the purpose of interrupting a performance. Resorting to the analysis of the “pateada”, we present a historical moment in which the behavior and subjectivity of the spectator would begin to be regulated towards a disciplined, moderated, and pedagogized body, and a new type of public-stage address would emerge.
Acoustic experience in the devotional scenology
Authors: Cirino Giovanni
Published: February 2025

ABSTRACT Acoustic experience in the devotional scenology – This article discusses the acoustic universe of a scenic practice strongly anchored in devotion to São Benedito. Black tradition music and its relations with popular religiosities on the north coast of São Paulo are thought of as a context from which scenic practices are carried out. From sound, musical and morphological aspects we investigated the connections between symbolic elements of different religiosities present in representations of wars between mouros (Moors) and cristãos (Christians).

ABSTRACT Musical resonances in the body and on the scene of black performance1 – Considering the power of musicality in the performing arts as a device for body states and, also, with regard to the textures and ambiences that collaborate with dramaturgy, this article addresses the relationship between body, scene, music and Afro-Brazilian culture. To this end, the experience with the show Por cima do mar eu vim, produced by Núcleo Coletivo 22, in the city of Goiânia (GO), is used to discuss the way in which Afro-Amerindian musicality is capable of giving outlines to the contemporary scene, in order to attribute to it identity traits of what we can call black performance and Afro-Amerindian poetics, for instance.
Theaters of Sound: listening, immersion, strangeness
Authors: Martins José Batista Dal Farra
Published: February 2025

ABSTRACT Theaters of Sound: listening, immersion, strangeness – In the Theaters of sound, sound stages: sonority and visuality are in solidarity. The article develops in this field, in a theoretical and poetic mode, according to an axis that problematizes the concepts of immersion and strangeness, articulated with presence and absence. The essay is driven by conceptual prospecting, considerations on the anatomical incision of sound, on the relations between scene and technology, and a series of listening gestures, in dialogue with theatrical poetics, such as: Elettra, by Hugo von Hofmannsthal, with sound by Hubert Westkemper (2004); Ouverture Alcina, by Nevio Spadoni, with Ermanna Montanari and music by Luigi Ceccarelli (2009); Not I / Eu Não, by Samuel Beckett, with Maria Alice Vergueiro (1986) and Eislermaterial, directed by Heiner Goebbels (1998).

RESUMEN Documentos Sonoros, Resonancias Biográficas y Montaje para la Configuración de Constelaciones Idiorrítmicas: la mutua influencia entre Lola Arias y Ulises Conti – El tratamiento escénico y sonoro que experimentan las obras creadas a partir de la colaboración entre la autora y directora Lola Arias y el compositor Ulises Conti es fruto de la exploración de universos discursivos entendidos como materia viva en constante mutación. En el presente estudio nos proponemos realizar un mapeo de los trabajos surgidos de ese particular intercambio y analizar algunos de los rasgos sobresalientes de las obras de esxs artistas a partir de su mutua influencia. Retomando los postulados de Roland Barthes, sostenemos que a través de esas creaciones se configuran constelaciones idiorrítmicas a partir de las cuales se produce una combinación del tiempo personal y de la vivencia colectiva.

RESUMO De um ‘passado audível’ a outro, um mesmo protocolo de escuta?1 – Para estabelecer o diálogo científico que se inicia entre os membros do projeto francês L’écoute du théâtre [ECHO] (UMR THALIM – CNRS/ENS/Université Sorbonne Nouvelle) e a equipe da pesquisa Arquivos sonoros de teatro (FAPESP/Universidade de São Paulo), este artigo aborda uma questão delicada que poderá ser elucidada pela contribuição dessa parceria franco-brasileira: em que medida os conceitos e métodos dos Sound Studies norte-americanos e dos estudos sonoros franceses podem ajudar a tornar audíveis outras culturas e serem ao mesmo tempo enriquecidos por elas? Considerando as reflexões do próprio Sterne sobre a sua obra, The Audible Past (O passado audível), parto de nossa já longa experiência de pesquisa no tema para propor um início de resposta e de um plano de trabalho.
