Abstract In the county of Pedra Lavrada - PB, various mineral occurrences of pegmatite are observed with prominence at Alto Dois Irmãos - PB, where quartz, feldspar and mica are mined. The understanding of mineral constituents is fundamental to define their industrial employment and to implement improvements in the beneficiation process. The proposal of this research is the detailed characterization and proof of that part of the ore (quartz) considered waste, presenting low poisoning (Fe2O3) and high silica (SiO2) content, to enable its industrial use. Besides that, to minimize the environmental impact through the reuse of this waste, and to determine the correct utilization of the milling equipment. For the pegmatite characterization, done were density determination tests, mineralogical identification by X-ray diffraction (XRD), chemical analysis by fluorescents X-rays and morphological analysis by scanning electron microscopy (SEM/EDS). Then tests were done for the Work Index (WI) calculous and consequently the empirical determination of the dimensions (LxD) of the pebble mill. The sterile presented a medium density of 2.66g/cm³, majority chemical composition of silicon and oxygen and quartz as the main mineralogical stage, indicating that this material has high purity. The. The Work Index (WI) was 15.9 kwh/t showing that this material can be considered resistant to breaking in the grinding process. The necessary energy to the milling was defined in 11.52 kwh/st, that corresponds to 57.28 HP. This power allowed the mill selection with diammeter and length of 1.83m, that provides the production maximization and the energy saving.

ABSTRACT BACKGROUND: Nutritional status and growth curves can affect cognitive development, increase the risk of infection, and contribute to the development of chronic diseases. Its etiology is related to food, socioeconomic, and maternal conditions. However, to date, no data on these parameters exist in the state of Goiás, Brazil. OBJECTIVE: To compare the nutritional status and growth curves of children and adolescents in the city of Goiânia, Goiás, Brazil. DESIGN AND SETTING: This was a cross-sectional study. A total of 529 individuals were recruited from a primary health center in the municipality. METHODS: To assess nutritional status, the sample was divided into three categories: 3–4, 5–10, and 11–19 years, with z-score classification considering body mass index for age. The classification of growth curves was performed considering the median height values for age, assuming two references: (a) young Brazilian population and (b) one recommended for international use. The independent sample T-test was used to compare anthropometric variables. RESULTS: The results showed that the classification of eutrophics represents a predominant percentage between both sexes (men: 03–04 = 55.4%; 05–10 = 57.6%; 11–19 = 53.5 % and women: 03–04 = 53.5%; 05–10 = 63.9%; 11–19 = 56.9%), and growth curves showed differences in specific periods in both sexes. CONCLUSIONS: It can be concluded that children and adolescents from the city of Goiânia present as predominance the eutrophic nutritional status, followed by the risk of overweight, underweight, obesity, and malnutrition of both sexes.

ABSTRACT: This study evaluated the effect of the co-feeding (C) period on the growth and survival of larvae of the yo-yo loach Botia lohachata ornamental species during the weaning period from live food (LF) to inert food (IF). The breeders were subjected to induced spawning using crude pituitary homogenate. A total of 2,400 larvae were used with an average initial weight of 0.39 ± 0.09 mg and an average total length of 4.08 ± 0.21 mm, from a single breeding pair. The live food was newly hatched nauplii of Artemia franciscana, and the inert diet was a commercial ration with 55% crude protein and two particle sizes (142-350 µm and 350-500 µm). As the first food, all larvae received A. franciscana during the first six days, except for the fasting (NC) and inert food (IF) groups. The following co-feeding strategies were employed: C4 = 4 days of co-feeding, C8 = 8 days of co-feeding, C12 = 12 days of co-feeding, and LF = Artemia during the entire experimental period. The longest period with live food promoted better larval growth rates. The specific growth rate of larvae fed live food during the entire period (LF) was higher than that of the other groups, followed by the co-feeding strategies. There was no effect (P > 0.01) on larval survival in the LF, C12, C8, and C4 groups, which ranged from 41% to 53% after 30 days. Treatment R resulted in high mortality and low growth, suggesting that live food should be the first food source for B. lohachata larvae.

RESUMO: Este estudo teve como objetivo avaliar o efeito do período de co-alimentação (C) no crescimento e sobrevivência de larvas da espécie ornamental Botia lohachata durante o período de desmame de alimento vivo (LF) para alimento inerte (IF). Os reprodutores foram submetidos à desova induzida com homogeneizado de hipófise. Foram utilizadas 2.400 larvas com peso inicial médio de 0,39 ± 0,09 mg e comprimento total médio de 4,08 ± 0,21 mm, de um único casal reprodutor. O alimento vivo foi náuplios recém-eclodidos de Artemia franciscana, e a dieta inerte foi uma ração comercial com 55% de proteína bruta e dois tamanhos de partículas (142-350 µm e 350-500 µm). Como primeiro alimento, todas as larvas receberam A. franciscana durante os primeiros seis dias, exceto os grupos jejum (NC) e alimento inerte (IF). As seguintes estratégias de co-alimentação foram empregadas: C4 = 4 dias de co-alimentação, C8 = 8 dias de co-alimentação, C12 = 12 dias de co-alimentação e LF = Artemia durante todo o período experimental. O maior período com alimento vivo promoveu melhores taxas de crescimento larval. A taxa de crescimento específico das larvas alimentadas com ração viva durante todo o período (LF) foi maior que a dos demais grupos, seguida das estratégias de co-alimentação. Não houve efeito (P > 0,01) na sobrevivência larval nos grupos LF, C12, C8 e C4, que variou de 41% a 53% após 30 dias. O tratamento IN resultou em alta mortalidade e baixo crescimento, sugerindo que o alimento vivo deve ser a primeira fonte de alimento para as larvas de B. lohachata.

Cancer is one of the major causes of death worldwide, and breast cancer is the most prevalent and deadly type among women. Despite the side effects and the phenomena of chemoresistance associated with the drugs involved, chemotherapy remains the main therapeutic strategy to combat and control breast cancer. Therefore, several new classes of compounds against breast cancer have been explored, in an effort to identify new drug candidates with alternative mechanisms of action. The principal results of such exploration, focusing on caged xanthones, thiosemicarbazones and photosensitizers, are presented in this review, along with the main aspects of the drug discovery process against breast cancer. More specifically, the design, structure-activity relationship investigations and anti-breast cancer properties of these three classes are described and discussed in this work. worldwide women involved Therefore explored action exploration xanthones photosensitizers review specifically design structureactivity structure activity antibreast anti work

ABSTRACT Objective: To assess the impact of different vertical positions on lung aeration in patients receiving invasive mechanical ventilation. Methods: An open-label randomized crossover clinical trial was conducted between January and July 2020. Adults receiving invasive mechanical ventilation for > 24 hours and < 7 days with hemodynamic, respiratory and neurological stability were randomly assigned at a 1:1 ratio to the sitting position followed by passive orthostasis condition or the passive orthostasis followed by the sitting position condition. The primary outcome was lung aeration assessed using the lung ultrasound score (score ranges from 0 [better] to 36 [worse]). Results: A total of 186 subjects were screened; of these subjects, 19 were enrolled (57.8% male; mean age, 73.2 years). All participants were assigned to receive at least one verticalization protocol. Passive orthostasis resulted in mean lung ultrasound scores that did not differ significantly from the sitting position (11.0 versus 13.7; mean difference, -2.7; [95%CI -6.1 to 0.71; p = 0.11). Adverse events occurred in three subjects in the passive orthostasis group and in one in the sitting position group (p = 0.99). Conclusion: This analysis did not find significant differences in lung aeration between the sitting and passive orthostasis groups. A randomized crossover clinical trial assessing the impact of vertical positioning on lung aeration in patients receiving invasive mechanical ventilation is feasible. Unfortunately, the study was interrupted due to the need to treat COVID-19 patients. ClinicalTrials.gov registry: NCT04176445

ABSTRACT The fertilization management can contribute to a better agronomic performance of rice (Oryza sativa L.) plants in upland conditions. Thus, the objective in this study was to evaluate the development of rice plants fertilized with different doses of nitrogen and phosphorus in upland soil. The experiment was conducted in a greenhouse using pots containing soil collected in the soil top layer of a plinthic alitic Haplic Cambisol. The design was completely randomized with a 4 x 4 factorial scheme, corresponding to 0 (zero), 150, 300 and 450 kg ha-1 of phosphorus and 0 (zero), 100, 200 and 300 kg ha-1 of nitrogen. Plant height, shoot dry matter, grain weight and number of tillers were evaluated. Fertilization with nitrogen and phosphorus positively affects the growth and development of rice plants in Humaitá, Amazonas state, grown in upland soil up to doses between 200 and 300 kg ha-1 of N and around 300 kg ha-1 of P2O5, in a plinthic alitic Haplic Cambisol.

Abstract The reasons for procrastination in activities related to the writing of dissertations or thesis is relevant to reflect on whether procrastination contributes negatively to achieving academic goals. The aim of this work was to verify the intensity of reasons for procrastination in activities related to the elaboration of dissertations or theses among Brazilian students who are studying stricto sensu postgraduate courses in the business area. The instrument used in this study links the reasons for academic procrastination with fear of success and fear of failure. The sample analyzed the answers of 288 Brazilian students from the business area. Descriptive analyzes and between-group difference tests were performed. The results show that the certainty of being successful in carrying out the tasks was the reason with the greatest intensity of procrastination during the preparation of dissertations or theses; accounting students present a greater intensity of motives compared to economics students. The study shows that academic procrastination seems to be a dynamic behavior and is related to moments of solitude during which students need to dedicate themselves to write dissertations or theses.

Resumen: La economía circular (EC) se ha adoptado como una alternativa al modelo económico lineal, ya que transforma la forma en que se diseñan y consumen los productos. Las cadenas agroalimentarias son clave para asegurar la transición a un modelo de desarrollo sostenible en línea con los principios de la EC. Este estudio buscó implementar los conceptos de economía circular en la cadena productiva bananera del Ecuador, a través del diseño de prospectiva a partir del diagnóstico exhaustivo de los principales procesos de la cadena. La investigación se realizó de 2020 a 2022. La lista de verificación estudiada incluyó 91 ítems agrupados en nueve dimensiones: fuente o suministro de materiales, diseño, fabricación, círculo económico, distribución y ventas, consumo y uso, 4R, refabricación y sostenibilidad. Se evaluó un nivel medio de economía circular (CEL) (2,69 puntos sobre 5). También se aplicaron dos técnicas de aprendizaje automático (MLTs) máquina de vectores soporte (SVM), (con tres tipos de kernel: radial, lineal y polinomial) y una red neuronal (NN). En relación a los coeficientes de correlación de Spearman de la aplicación de las técnicas a los casos de estudio, fueron superiores a 0,90. El más confiable fue el SVM Regression-Linear Kernel, el cual tuvo un coeficiente cercano a 1. Finalmente, se proponen diversas opciones de agregación de valor para aprovechar la gran cantidad de residuos generados en el sistema de producción de banano. Las opciones propuestas incluyen procesos de aumento de valor, que van desde fertilizantes orgánicos, biocombustibles, materiales para el tratamiento de aguas residuales y la producción de bioplásticos y nanopartículas, que pueden implementarse utilizando el enfoque de CE.

Abstract: The circular economy (CE) has been adopted as an alternative to the linear economic model, since it transforms the way products are designed and consumed. Agri-food chains are key to ensuring the transition to a sustainable development model in line with the principles of CE. This study sought to implement the concepts of circular economy at the Ecuador's banana production chain, through the design of prospective from the exhaustive diagnosis of the main processes of the chain. The research was conducted from 2020 to 2022. The studied checklist included 91 items grouped into nine dimensions: source or supply of materials, design, manufacturing, economic circle, distribution and sales, consumption and use, 4R, re-manufacturing, and sustainability. A medium circular economy level (CEL) was evaluated (2.69 points out of 5). Two machine learning techniques (MLTs) were also applied support vector machine (SVM), (with three types of kernel: radial, linear and polynomial) and a neural network (NN). In relation to the Spearman correlation coefficients of the application of the techniques to the study cases, they were higher than 0.90. The most reliable was the SVM Regression-Linear Kernel, which had a coefficient close to 1. Finally, various value-adding options are proposed in order to take advantage of the large amount of waste generated in the banana production system. The proposed options include value-augmentation processes, ranging from organic fertilizers, biofuels, materials for wastewater treatment, and the production of bioplastics and nanoparticles, which can be implemented using the CE approach.

In this work, a visible-light-driven synthesis of alkynyl selenides using [BMIm]BF4 as an environmentally friendly solvent and without the addition of metal catalysts, photosensitizers, directing-groups, or bases is reported. The target compounds were obtained in moderate to good yields with good functional group tolerance by the reaction of diorganoyldiselenides with 1-bromoalkynes proceeding through a radical mechanism.

The approach proposed here is focused on the separation of light fractions (corresponding to fatty acids with molecular chains between 8 to 14 carbons) from the fatty acid methyl esters (FAMES) of the biodiesel obtained by the reaction of transesterification of triacylglycerols in the kernel gueiroba oil (Syagrus oleracea) with methanol. The whole biodiesel was fractionated through atmospheric distillation in a single glass column with thermal insulation. Such a separation produced 59.79% in volume of light biodiesel (LB), which was mixed with the standard mineral Jet-A1 kerosene (cf. ASTM, corresponding to the QAV-1, cf. the Brazilian standard of the ANP) for aviation, in the volumetric ratios LB:Jet-A1 2:98; 5:95; 10:90 and 20:80. The values of density, water content, distillation analysis, flash point, calorific value and freezing point were carefully checked for their compliance with the official recommendations for jet fuel. It was found that the mixtures richest in the Jet-A1 mineral kerosene, that is, those containing no more than 5% LB by volume, well meet the recommended standards and are technologically viable to replace pure Jet-A1 kerosene for the propulsion of turbine aircraft.

Chemical modification reactions are viable alternatives for improving the properties of starch because they allow the insertion of molecules that change the original behavior of the polymer. Glycidyl methacrylate (GMA) is an example of a vinylic molecule added to starch to decrease its hydrophilicity and improve mechanical properties. This modification reaction is affected by parameters like the volume of the modifier, time, and temperature. Furthermore, the correlation between these parameters might change the response of an individual parameter on the degree of substitution (DS), crystallinity (Xc), and molecular-weight-related parameters. This work evaluated how these effects and their correlations would affect DS, Xc, molecular weight, and polydispersity index (PDI) of starch. The results suggested that, while higher volumes of GMA and temperatures decreased the DS and Xc, the correlation between them increased the DS by 2.47, and Xc by 1.25. On the other hand, higher temperatures also favored the occurrence of hydrolysis. Also, although none of the parameter correlations had a significant effect on the assessed properties (at 95%), the statistical analysis confirmed that the correlation between two parameters changed the effect of individual parameters.

RESUMEN Objetivo. Determinar la tendencia temporal de la mortalidad y los años de vida perdidos por muerte o ajustados por discapacidad (AVAD) de hombres por accidentes de motocicleta en América Latina y el Caribe en el período 2010-2019, a partir de las estimaciones del estudio de la carga mundial de enfermedades (CME). Métodos. En este estudio ecológico se analizaron las series temporales mediante el modelo de regresión lineal segmentada (joinpoint), con cálculo y comprobación del cambio porcentual anual y del cambio porcentual anual promedio, con un intervalo de confianza del 95%. Resultados. La región de América Latina y el Caribe definida por el estudio de la CME ocupó el primer lugar a nivel mundial en mortalidad y AVAD de motociclistas varones de 15 a 49 años en el 2019. Las tasas tuvieron un notable aumento del 2010 al 2013, y ambas registraron una reducción importante después de ese período. En la década analizada, la subregión de América Latina Tropical (Brasil y Paraguay) presentó las mayores tasas de mortalidad y de AVAD en la población de estudio, pero fue la única con una reducción importante de las mismas. La subregión del Caribe (Antigua y Barbuda, Bahamas, Barbados, Belice, Bermudas, Cuba, Dominica, Granada, Guyana, Haití, Islas Vírgenes de Estados Unidos, Jamaica, Puerto Rico, República Dominicana, Saint Kits y Nevis, San Vicente y las Granadinas, Santa Lucía, Suriname, y Trinidad y Tabago) mostró un aumento importante de ambas tasas, mientras que América Latina Andina (Bolivia, Ecuador y Perú) y América Latina Central (Colombia, Costa Rica, El Salvador, Guatemala, Honduras, México, Nicaragua, Panamá y Venezuela) se mantuvieron estables. Conclusiones. Los datos refuerzan la importancia de las actividades de vigilancia destinadas a prevenir los accidentes de motocicleta, puesto que la reducción observada de las tasas aún es insuficiente para abordar la morbimortalidad por accidentes de tráfico como problema de salud pública.

ABSTRACT Objective. To identify the temporal trend in mortality and years of life lost to death or disability (DALY) due to motorcycle accidents in males from Latin America and the Caribbean from 2010 to 2019, using estimates produced by the Global Burden of Disease (GBD) study. Method. In this ecological study, the time series was analyzed using a piecewise linear regression model (joinpoint) to estimate and test the annual percent change and the average annual percent change with a 95% confidence interval. Results. The super-region defined by GBD 2019 as Latin America and the Caribbean ranked first globally in mortality and DALY for male motorcyclists aged 15-49 in 2019. Rates increased significantly from 2010 to 2013, with a significant reduction in both after this period. During the analyzed decade, the Tropical Latin America sub-region (Brazil and Paraguay) had the highest mortality and DALY rates in the population of interest; nevertheless, this was the only sub-region achieving a significant reduction in these rates. The Caribbean sub-region (Bermuda, Dominica, Suriname, Guyana, Belize, Bahamas, Puerto Rico, Saint Lucia, Dominican Republic, Haiti, Saint Kitts and Nevis, U.S. Virgin Islands, Grenada, Trinidad and Tobago, Barbados, Saint Vincent and the Grenadines, Antigua and Barbuda, Cuba e Jamaica) showed a significant increase in both rates over the same period, while Andean Latin America (Ecuador, Bolivia and Peru) and Central Latin America (Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Nicaragua, Panama, Honduras, and Venezuela) remained stable. Conclusions. The data underscore the importance of developing surveillance actions aimed at preventing motorcycle accidents, since the observed declining rates are still insufficient to address the morbidity and mortality associated with road accidents as a public health problem.

As taxas aumentaram significativamente de 2010 a 2013, havendo redução significativa de ambas após esse período. Durante a década analisada, a sub-região da América Latina Tropical (Brasil e Paraguai) apresentou as maiores taxas de mortalidade e DALY na população em estudo, porém foi a única com redução significativa das mesmas; a sub-região do Caribe (Bermudas, Dominica, Suriname, Guiana, Belize, Bahamas, Porto Rico, Santa Lúcia, República Dominicana, Haiti, São Cristóvão e Névis, Ilhas Virgens/EUA, Granada, Trinidad e Tobago, Barbados, São Vicente e Granadinas, Antígua e Barbuda, Cuba e Jamaica) apresentou aumento significativo de ambas as taxas, enquanto América Latina Andina (Equador, Bolívia e Peru) e América Latina Central (Colômbia, Costa Rica, El Salvador, Guatemala, México, Nicarágua, Panamá, Honduras e Venezuela) permaneceram estáveis. Conclusões. Os dados reforçam a importância das ações de vigilância destinadas à prevenção de acidentes motociclísticos, uma vez que os resultados de queda nas taxas ainda são insuficientes frente à morbimortalidade no trânsito como problema de saúde pública.

Abstract This study aimed to understand the meanings that homosexual and bisexual women give to the state of health and illness and the way they evaluate their own state of well-being. It is a qualitative research study consisting of the accounts of 14 women from the municipality of Imperatriz, Maranhão, Brazil. Medical anthropology and gender studies contributed to analyzing the categories “Dimensions of health and disease” and “Looking at one’s own health”. These sections discuss the dualistic mind-body perspectives that etiologically characterized the health-disease process in these interlocutors’ view. In addition, the sociocultural context was understood as shaping the way they translated and evaluated their own health condition, a context crossed by their bisexual and lesbian experience. Therefore, the interviewees’ sexual identities and behaviors challenge the rigid way the health-disease process is interpreted by biomedical knowledge, questioning practices that marginalize these women in health care services.

Resumo Este estudo teve como objetivo compreender os sentidos que mulheres homossexuais e bissexuais dão ao estado de saúde e doença e a forma como avaliam o seu próprio quadro de bem-estar. Tratou-se de uma pesquisa qualitativa constituída pelos relatos de 14 mulheres do município de Imperatriz, Maranhão, Brasil. A antropologia médica e os estudos sobre gênero contribuíram para analisar as categorias “Dimensões da saúde e da doença” e “O olhar sobre a própria saúde”. Nessas seções, são discutidas as perspectivas dualistas mente-corpo que caracterizavam etiologicamente o processo saúde-doença na visão dessas interlocutoras. Ademais, o contexto sociocultural foi compreendido como formatador da maneira como traduziam e avaliavam a sua própria condição de saúde, contexto esse atravessado pela vivência bissexual e lésbica. Portanto, as identidades e os comportamentos sexuais das entrevistadas friccionam a rigidez como o processo saúde-doença é interpretado pelo saber biomédico, questionando práticas que marginalizam essas mulheres nos serviços de assistência à saúde.

Abstract In this review, we describe recent advances in understanding the relationship between epigenetic changes, especially DNA methylation (DNAm), with hypersensitivity and respiratory disorders such as asthma in childhood. It is clearly described that epigenetic mechanisms can induce short to long-term changes in cells, tissues, and organs. Through the growing number of studies on the Origins of Health Development and Diseases, more and more data exist on how environmental and genomic aspects in early life can induce allergies and asthma. The lack of biomarkers, standardized assays, and access to more accessible tools for data collection and analysis are still a challenge for future studies. Through this review, the authors draw a panorama with the available information that can assist in the establishment of an epigenetic approach for the risk analysis of these pathologies.
