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

Computer-aided drug planning strategies have contributed to the research and development of new anti-tuberculosis (TB) drugs to avoid resistance and reduce treatment time and the number of drugs used in therapy. The aim of work was to carry out a docking study to identify the possible mechanism of action of the hits LabMol73, 84, 86 and 93 previously tested in the Microplate Assay Blue Alamar (MABA), Low Oxygen Recovery Assay (LORA) assays in sensitive strains from M.tb. H37Rv and resistant to the standard drugs rifampicin and isoniazid, due to the promising inhibitory result against these strains, suggesting a different mechanism of action from existing drugs. The reverse virtual screening was performed on the Pharmmapper platform, which identifies targets by pharmacophoric model. The most promising targets have been validated. The DM was performed in the OpenEye Maestro program for analysis of poses and energy score. Sixteen targets M.tb. H37Rv were identified and only nine demonstrated viability for computational testing. The most promising results were observed in the mycolic acid cyclopropane synthase (PDB:1L1E) and pantothenate synthetase (PDB:1N2B) targets. Since, in the target 1L1E score results obtained were between -6.998 to -7.767 kcal/mol. In the 1N2B target the results were between -6.421 to -7.293 kcal/mol, presenting themselves as the most promising targets due to their similar score scores between the two targets suggesting that the mechanism of action may be the inhibition of one of these targets. These targets proved to be promising for elucidating the mechanism of action of the analyzed nitro heteroaryl chalcones, as they corroborate the assay against resistant strains, demonstrating that standard drugs have activity against other targets and also because mycolic acid and pantothenate are directly linked to virulence and resistance of M.tb. H37Rv.

Resumo As condições de vida e trabalho às quais foram submetidos homens e mulheres escravizados no processo produtivo do açúcar nos engenhos são fatores essenciais para entender a dinâmica da escravidão na América Portuguesa. Nas entrelinhas das recomendações e admoestações transmitidas aos senhores de engenhos do Nordeste, bem como nas descrições das tarefas executadas pelos escravos em diferentes setores da propriedade encontradas nos textos de clérigos setecentistas como padre Antônio Vieira, Jorge Benci, Manuel Ribeiro Rocha e, principalmente, por André João Antonil, é possível entrever essas condições e as relações de poder, que se vinham consolidando desde o século XVII. Frutos do estágio do desenvolvimento das forças produtivas no setor agrícola e de fatores inerentes ao escravismo moderno, essas condições permaneceram as mesmas no século XIX e podiam ser encontradas em outras regiões produtoras de açúcar no Sudeste, conforme se verifica nos relatos produzidos pelos viajantes europeus que visitaram essas propriedades. Portuguesa Nordeste Vieira Benci principalmente Antonil poder XVII moderno Sudeste propriedades

Abstract Theliving and working conditions to which enslaved men and women were subjected in mills during the production process of sugar are essential to understand the dynamics of slavery in Portuguese America. Between the lines of the recommendations and admonitions transmitted to sugar mill masters in the northeastern region, as well as in the description of tasks performed by the slaves in different sectors of the property that can be found in texts written by seventeenth--century clerics, such as priest Antônio Vieira, Jorge Benci, Manoel Ribeiro Rocha and, mainly, André João Antonil, it is possible to glimpse such conditions, which had been developing since the seventeenth century. Being the result of the development stage of the productive forces in the agricultural sector and factors inherent to modern slavery, these conditions remain the same in the nineteenth century. They could also be found in other sugar-producing regions in the Southeast, as the reports produced by European travelers who visited these properties show.

RESUMO: Este estudo verificou se o tamanho de amostra afetaria a precisão da análise de variância em experimentos com mudas de couve-flor. Um experimento foi conduzido onde o número de folhas, comprimento de parte aérea, raiz e total foram mensurados. Para cada variável, reamostragens com reposição foram realizadas em cenários amostrais de 1, 2, ..., 100 mudas por unidade experimental e o tamanho de amostra foi definido para os componentes de variância por meio de modelos de Schumacher e pontos de máxima curvatura. Os quadrados médios da análise de variância sofrem interferência direta do número de mudas amostradas. A amostragem de 16 mudas por unidade experimental é suficiente para estimar a análise de variância de forma confiável, promovendo satisfatórios ganhos de precisão ao comparar-se com a amostragem de apenas uma muda por unidade experimental.

ABSTRACT: This study verified whether sample size would affect the precision of the analysis of variance in experiments with cauliflower seedlings. An experiment was carried out where the number of leaves and shoot, root and total length were measured. For each variable, resamplings with repositions were performed in sample scenarios of 1, 2, …, 100 seedlings per experimental unit, and the sample size was defined for the variance components through Schumacher models and maximum curvature points. The mean squares of the analysis of variance suffer direct interference from the number of sampled seedlings. The sampling of 16 seedlings per experimental unit is enough to estimate the analysis of variance reliably, promoting satisfactory precision gains compared to the sampling of only one seedling per experimental unit.

RESUMO: Os objetivos deste estudo foram analisar a interferência do tamanho amostral no teste de não aditividade de Tukey e encontrar o tamanho de amostra para otimizar o teste para a produtividade de grãos em soja. Seis experimentos em delineamento de blocos ao acaso foram conduzidos com 20 ou 30 cultivares de soja em três repetições de cada tratamento. A produtividade de grãos foi definida por planta, totalizando 9.000 plantas amostradas. A seguir, foram simulados cenários amostrais de até 100 plantas, estimando a estatística F para um grau de liberdade do erro em cada cenário. Após, foi definido o tamanho amostral ótimo via modelos de potência e pontos de máxima curvatura. Os resultados mostram que o número de plantas amostradas por unidade experimental influencia as estimativas do teste de não aditividade de Tukey. Além disso, a amostragem de 14 a 19 plantas por unidade experimental possibilita manter a acurácia do teste.

ABSTRACT: This study analyzed the interference of sample size on Tukey’s test for non-additivity and found the sample size to optimize the test for soybean grain yield. Six experiments were conducted in a completely randomized block design with either 20 or 30 cultivars and three repetitions of each treatment. Grain yield was determined per plant, totaling 9,000 sampled plants. Next, sample scenarios up to 100 plants were simulated, estimating F statistic for a degree of freedom of the error in each scenario. After that, the optimal sample size was defined via power models and maximum curvature point. Results showed the number of sampled plants per experimental unit influences the estimates of Tukey’s test for non-additivity. Also, the sampling of 14 to 19 plants per experimental unit allows for maintaining the accuracy of the test.

Abstract 2-Phenylethynyl-Butyltellurium (PEBT) is a synthetic organotellurium compound that has shown various pharmacological properties on mammals without any signs of toxicity, but its effects on insects have not been reported before. Therefore, the aim of this study was to assess whether acute exposure to PEBT would promote an insecticidal effect against Drosophila melanogaster. The flies were exposed to three concentrations of PEBT (0.325 µmol L-1, 1.300 µmol L-1, and 5.200 µmol L-1) and a control solution (vehicle), using 450 flies per treatment (three repetitions of 150 flies), for 48 hours. Negative geotaxis and open field tests were performed (in vivo) after 24 and 48h, and acetylcholinesterase (AChE) activity was assessed (ex vivo) after 48h. Also, the mortality rate, 50% Lethal Concentration (LC50), 80% Lethal Concentration (LC80), and 95% Lethal Concentration (LC95) were calculated. Our results show that PEBT presented insecticidal activity against Drosophila melanogaster at all tested concentrations, which caused locomotor impairment and increased acetylcholinesterase activity in the flies’ heads.

Abstract Data on clinical management options for sleep bruxism in the primary dentition are inconclusive. This umbrella review aimed to synthesize the available evidence from systematic reviews (SRs) on the associated factors and treatment approaches for clinical management of sleep bruxism in children. A search was conducted in the MEDLINE/PubMed, Web of Science, Embase, and OpenGrey databases up to March 2022. SRs published on sleep bruxism in children containing data on associated factors or treatment outcomes were included. The AMSTAR-2 tool was used to assess the methodological quality of SRs. The search identified 444 articles, of which six were included. Sleep conditions, respiratory changes, personality traits, and psychosocial factors were the associated factors commonly identified. Treatments included psychological and pharmacological therapies, occlusal devices, physical therapy, and surgical therapy. All SRs included presented a high risk of bias. Overlapping of the included studies was considered very high. The best evidence available to date for the management of sleep bruxism in children is based on associated factors, with sleep duration and conditions, respiratory changes, as well as personality traits and psychosocial factors being the most important factors commonly reported by studies. However, there is currently insufficient evidence to make recommendations for specific treatment options.

ABSTRACT The Caatinga biome in Brazil comprises the largest and most continuous expanse of the seasonally dry tropical forest (SDTF) worldwide; nevertheless, it is among the most threatened and least studied, despite its ecological and biogeographical importance. The spatial distribution of volumetric wood stocks in the Caatinga and the relationship with environmental factors remain unknown. Therefore, this study intends to quantify and analyze the spatial distribution of wood volume as a function of environmental variables in Caatinga vegetation in Bahia State, Brazil. Volumetric estimates were obtained at the plot and fragment level. The multiple linear regression techniques were adopted, using environmental variables in the area as predictors. Spatial modeling was performed using the geostatistical kriging approach with the model residuals. The model developed presented a reasonable fit for the volume m3 ha with r2 of 0.54 and Root Mean Square Error (RMSE) of 10.9 m3 ha–1. The kriging of ordinary residuals suggested low error estimates in unsampled locations and balance in the under and overestimates of the model. The regression kriging approach provided greater detailing of the global wood volume stock map, yielding volume estimates that ranged from 0.01 to 109 m3 ha–1. Elevation, mean annual temperature, and precipitation of the driest month are strong environmental predictors for volume estimation. This information is necessary to development action plans for sustainable management and use of the Caatinga SDTF in Bahia State, Brazil.

Abstract We propose a symbolic investigation of two publications posted on Instagram by Heineken and Carrefour. This choice was made because they represent the idea of “political correctness”. The objective is to analyze these communications from an imaginary theories perspective, as suggested by M. Contrera, G. Durand, C. Jung, and others, as this action allows the identification of hidden aspects in the publications and the perception of what information is there, however, in addition to the obviousness of commercial interests that aim to reinforce the brand’s good public reputation. Our conclusions suggest that it is possible to change this biased perception by building a critical mass sufficiently qualified to recognize these mechanisms that lead to communication one-sidedness.

Resumen Se propone la investigación simbólica de dos publicaciones en Instagram por Heineken y Carrefour. Esta elección se hizo porque representan la idea de “corrección política”. El objetivo es analizar estas comunicaciones a la luz de teorías imaginarias, como lo sugieren M. Contrera, G. Durand, C. Jung y otros, ya que esta acción permite identificar aspectos ocultos en las publicaciones y la percepción de qué información hay allí, sin embargo, además de la evidencia de intereses comerciales que apuntan a reforzar la buena reputación pública de la marca. Las conclusiones sugieren que es posible cambiar esta percepción sesgada construyendo una masa crítica, suficientemente calificada para reconocer estos mecanismos que conducen a la unilateralidad de la comunicación.

Resumo Propõe-se a investigação simbólica de duas publicações postadas no Instagram pela Heineken e pelo Carrefour. Essa escolha se deu por estas representarem a ideia do “politicamente correto”. O objetivo é analisar estas comunicações à luz das teorias do imaginário, conforme sugerem M. Contrera, G. Durand, C. Jung e outros, pois tal ação permite a identificação de aspectos escamoteados nas publicações e a percepção de quais informações estão ali, porém, além das obviedades dos interesses comerciais que visam reforçar a boa reputação pública da marca. As conclusões sugerem que é possível a mudança dessa percepção enviesada a partir da construção de uma massa crítica, suficientemente capacitada para reconhecer estes mecanismos que levam a uma unilateralidade comunicacional.

ABSTRACT The aim of this study was to assess yield components and grain yield of soybean cultivars in response to sowing densities. For this, two soybean cultivars and five sowing densities were tested, in a two-factor scheme. The following yield components were measured by the end of the cycle: plant height; insertion height of the first pod; number of nodes per plant; number of pods with one, two, three and four grains; number of pods per plant; number of grains per plant; weight of a thousand grains; humidity and grain yield. Sowing densities did not cause significant variations of grain yield (bags ha-1) for any cultivar, however, higher populational densities promoted a reduction in the number of pods with two and three grains, as well as a reduction in the total number of pods and grains per plant for both cultivars. Cultivar NS 5700 IPRO was the most productive, with a higher number of pods with two and three grains and number of pods and grains per plant.

RESUMO: O girassol produz aquênios e óleo de qualidade, além de servir para produção de silagem, forragem e biodiesel. A modelagem de crescimento permite conhecer o padrão de crescimento da cultura e otimizar o manejo. O objetivo deste trabalho foi caracterizar o crescimento da cultivar de girassol Rhino por meio dos modelos Logístico e Gompertz e fazer considerações a respeito do manejo com base em pontos críticos. Os dados utilizados são oriundos de três ensaios de uniformidade com a cultivar de girassol confeiteiro Rhino, conduzidos na área experimental da Universidade Federal de Santa Maria, Campus Frederico Westphalen, na safra 2019/2020. Foram realizadas 14, 12 e 10 avaliações semanais de altura em 10 plantas, respectivamente, no primeiro, segundo e terceiro ensaio. Os dados foram ajustados em função da soma térmica acumulada. Os parâmetros foram estimados por meio do método dos mínimos quadrados ordinários, usando o algoritmo de Gauss-Newton. A qualidade de ajuste dos modelos aos dados foi medida pelo coeficiente de determinação ajustado, critério de determinação de Akaike, critério bayesiano de informação, e por meio da não linearidade intrínseca e paramétrica. Foram determinados os pontos de inflexão (IP), máxima aceleração (MAP), máxima desaceleração (MDP) e desaceleração assintótica (ADP). As análises estatísticas foram realizadas com Microsoft Office Excel® e o software R. Os modelos descreveram de forma satisfatória a curva de crescimento da altura do girassol, fornecendo parâmetros com interpretações práticas. O modelo Logístico apresenta melhor qualidade de ajuste, sendo o mais adequado para caracterização da curva de crescimento. Os pontos críticos estimados fornecem informações importantes para o manejo da cultura. As plantas daninhas devem ser controladas até o MAP. As aplicações de fertilizantes em cobertura devem ser realizadas entre MAP e IP. O ADP é um indicador de maturidade, após atingir este ponto, as plantas podem ser colhidas para a produção de silagem sem perda de volume e qualidade.

ABSTRACT: Sunflower produces achenes and oil of good quality, besides serving for production of silage, forage and biodiesel. Growth modeling allows knowing the growth pattern of the crop and optimizing the management. The research characterized the growth of the Rhino sunflower cultivar using the Logistic and Gompertz models and to make considerations regarding management based on critical points. The data used come from three uniformity trials with the Rhino confectionery sunflower cultivar carried out in the experimental area of the Federal University of Santa Maria - Campus Frederico Westphalen in the 2019/2020 agricultural harvest. In the first, second and third trials 14, 12 and 10 weekly height evaluations were performed on 10 plants, respectively. The data were adjusted for the thermal time accumulated. The parameters were estimated by ordinary least square’s method using the Gauss-Newton algorithm. The fitting quality of the models to the data was measured by the adjusted coefficient of determination, Akaike information criterion, Bayesian information criterion, and through intrinsic and parametric nonlinearity. The inflection points (IP), maximum acceleration (MAP), maximum deceleration (MDP) and asymptotic deceleration (ADP) were determined. Statistical analyses were performed with Microsoft Office Excel® and R software. The models satisfactorily described the height growth curve of sunflower, providing parameters with practical interpretations. The Logistics model has the best fitting quality, being the most suitable for characterizing the growth curve. The estimated critical points provide important information for crop management. Weeds must be controlled until the MAP. Covered fertilizer applications must be carried out between the MAP and IP range. ADP is an indicator of maturity, after reaching this point, the plants can be harvested for the production of silage without loss of volume and quality.

RESUMO: Este estudo comparou quatro métodos para definir o tamanho amostral ideal por unidade experimental para estimar a média experimental geral para o comprimento total, comprimento de parte aérea, comprimento de raiz e número de folhas de mudas de couve-flor. Um experimento foi conduzido no qual foram medidos o número de folhas, o comprimento total, de parte aérea e de radícula, e foram testados os métodos: geral, de distâncias perpendiculares, resposta linear platô e spline. Enquanto o método geral pode sub ou superestimar o tamanho amostral e a amostragem de 10 mudas sugerida pelo método spline ainda se encontra muito distante do ponto de estabilização da curva, os métodos de distâncias perpendiculares e resposta linear platô são recomendados por obterem resultados que corresponderam a amplitudes de intervalos de confiança menores. Portanto, de acordo com o método de distâncias perpendiculares, pelo menos 15 mudas por unidade experimental são necessárias para estimar a média experimental geral de mudas de couve-flor confiavelmente para as variáveis aqui mensuradas.

ABSTRACT: This study compared four methods for defining the ideal sample size per experimental unit to estimate the overall experimental mean for the total length, shoot length, root length, and the number of leaves of cauliflower seedlings. An experiment was carried out where the number of leaves, shoot, root, and total length were measured, and the general, perpendicular distance, linear response plateau, and spline methods were tested. While the general method may under or overestimate sample size and the sampling of 10 seedlings suggested by the spline method is still too far from the stabilization point of the curve, the perpendicular distance and linear plateau response methods are recommended to obtain results corresponding to narrower confidence interval widths. Therefore, according to the perpendicular distance method, at least 15 seedlings per experimental unit are required to estimate the overall experimental mean of cauliflower seedlings reliably for the traits here measured.

Abstract Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.
