The use of materials such as organofunctionalized silica for application in solid phase extraction (SPE) allows the preconcentration of several ions, including Pt, and subsequent detection. This work aims to synthesize and characterize an organofunctionalized silica (Sil-TMSDT) with the silylant N’(trimethoxysilyl)propylethylenetriamine and its application as a solid phase in the preconcentration Pt4+ ions in aqueous media, using detection by flame atomization atomic absorption spectroscopy (FAAS). The Fourier-transform infrared spectroscopy (FTIR) spectra and scanning electron microscopy (SEM) coupled with energy-dispersive spectroscopy (EDS) confirmed the aminofunctionalization of the silica. For the adsorption process, a preconcentration mini-column with 200 mg of Sil-TMSDT, a solution of 0.485 mg L−1 of K2[PtCl6] at pH 10 and HNO3 0.5 mol L−1 as eluent were used, obtaining an enrichment factor of 15-fold with retention efficiency higher than 99%. The Pt4+ ion determined by FAAS showed a linear response between 0.02 and 0.40 mg L−1; a linear coefficient where R = 0.9981; a 16-fold preconcentration factor; a limit of quantification (LOQ) and limit of detection (LOD) of 0.045 and 0.014 mg L−1, respectively. The proposal system showed analytical applicability to determining Pt4+ ion in an aqueous medium and could be used to detect traces of this potentially toxic metal in biological fluids such as urine and blood.

Analysis of variance (ANOVA)-simultaneous component analysis (ASCA) is a method of choice for factorial design studies of environmental impacts on plant metabolomes and can be used to quantitatively carry out this comparative analysis. The impacts of seven mixture design extractor systems made up of ethanol, dichloromethane, and hexane and their 1:1 binary and 1:1:1 ternary solvents for several replicate experiments (n = 3, 4, 5) were assessed using ASCA models determined from Fourier-transform infrared (FTIR), near-infrared (NIR), and UV-Vis spectroscopic measurements on yerba mate leaf extracts. This analysis considered two-factor effects: secondary sexual dimorphism (male and female plants) and cultivation systems (monoculture and agroforestry), as well as their interaction effect. The three binary solvents were found to be more efficient extractor systems for all four detectors as they found 83 main and interaction effects significant at or above the 95% confidence level compared with only 47 for the pure solvent extracts. Binary solvent extracts resulted in averages between 44.04 and 86.61% for the ASCA total effect variances compared with 40.62 to 71.07% for pure extractors. Of the 60 significant effects found for experiments with 5 repetitions 53 or 88% were obtained with only triplicate determinations. The choice of spectroscopic technique and solvent system have large impacts on metabolomic analysis results.

ABSTRACT Purpose: Myopia, or nearsightedness, is one of the most common eye conditions worldwide. However, a comparison of the effectiveness of different laser-assisted interventions is lacking. Thus, we aimed to compare the efficacy and safety of LASIK and IntraLASIK in addressing myopia. Methods: The study was conducted in two ophthalmology clinics in Beijing, China, in 2022. A total of 84 patients (152 eyes) with different degrees of myopia were examined and underwent LASIK (n=46, 80 eyes) or IntraLASIK (n=38, 72 eyes). Keratometry, corneal topography, pachymetry, visual acuity evaluation, and corneal biomechanical analysis were performed before and after the intervention. Results: IntraLASIK produced more precise flaps than LASIK, with deviations of <8 mm and 0.1 mm from the intended thickness and diameter, respectively. LASIK resulted in nonuniform flaps, with thickness deviations of 5-86 mm. IntraLASIK demonstrated a superior efficacy for patients with severe myopia and thin corneas, with a mean spherical equivalent of 0.9 D at 6 months compared to the 1.4 D for LASIK. Approximately 91% and 83% of the patients with mild to moderate and severe myopia, respectively, achieved results within ± 0.49 D from the refractive target with IntraLASIK. Conclusions: Corneal hysteresis and corneal resistance factor decreased with an increase in laser intensity, and they decreased faster with thinner corneas. Thus, IntraLASIK is more useful than LASIK in patients with thin corneas and severe myopia.

ABSTRACT: With advancements in coffee cultivation, several traits may be considered in selection of plants, which must exhibit a set of favorable characteristics. The outturn index, defined as the relationship between the mass of mature fruit and processed beans, emerges as a key factor influencing productivity. This study characterized the outturn over two harvests of 57 clones marketed in the public domain and 10 registered cultivars. The analysis considers the effects of genotypes, measurements, and genetic progress achieved through plant selection. According to the maturation cycle of each clone, washed samples of cherry coffee were collected considering a completely randomized factorial design for characterization of the effects of genotypes, years, and the genotype × years (GY) interaction. The drying, peeling, and the outturn index were individually assessed. Despite the significant effects of the GY interaction, genotypes demonstrated minimal alterations in their ranking across measurements. Clones with higher outturn, including LB30, BRS1216, LB12, N7, LB10, LB20, BRS3220, and AS5, exhibited an average outturn of 25.51%, reflecting a gain of 12.17%. Conversely, clones with lower outturn, such as BG180, GJ30, GJ20, AS7, AS10, P42, N1, and P60, had an average of 19.15%, indicating a reduction of 14.02% compared to the general mean. Analyzing the distribution of the outturn values, 19.4%, 62.7%, and 17.9% of genotypes were classified as high, medium, and low outturn, respectively, providing valuable insights for optimal cultivation strategies.

RESUMO: Com o avanço da cafeicultura, múltiplas características devem ser consideradas na seleção de plantas, que devem apresentar um conjunto de atributos favoráveis. O rendimento, definido como a relação de massas entre os frutos maduros e os grãos processados, é um importante componente da produtividade. Este estudo tem como objetivo caracterizar o rendimento ao longo de duas colheitas de 57 clones comercializados em domínio público e 10 cultivares registradas. A análise considera efeitos de genótipos, medições e estimativas de ganhos com a seleção. De acordo com o ciclo de maturação de cada clone, amostras de café cereja foram colhidas considerando um delineamento fatorial inteiramente ao acaso para a caracterização dos efeitos de genótipos, anos e interação genótipo × anos (GA). A secagem, o descascamento e o rendimento foram avaliados individualmente. Apesar dos efeitos significativos da interação GA, os genótipos apresentaram pequenas mudanças no ordenamento de uma medição para a outra. Clones com maior rendimento, entre eles, LB30, BRS1216, LB12, N7, LB10, LB20, BRS3220 e AS5 apresentaram rendimento médio de 25,51% associado a estimativas de ganho de 12,17%. Por outro lado, clones de menor rendimento, como BG180, GJ30, GJ20, AS7, AS10, P42, N1 e P60 tiveram uma média de 19,15% associada a uma redução de 14,02%. A partir da distribuição dos valores, 19,4, 62,7 e 17,9% dos genótipos apresentaram rendimento classificados como alto, médio e baixo, subsidiando o melhor cultivo dos genótipos avaliados.

ABSTRACT The physiological quality of soya bean seeds is a determining factor in establishing the crop in the field. The aim of the present study was to evaluate the physiological quality of soya bean seeds produced by plants grown from seeds of different sizes in two crop seasons. The BS 2606 SOYTECH, NS 6700 IPRO, NA 5909 RR, BS IRGA 1642 IPRO and LANÇA 58i60 IPRO cultivars were used, sown in 2019/2020 and 2020/2021. The experimental design was of randomised blocks, with treatments comprising seeds from plants grown from seeds of three sieve sizes (5.5, 6.0 and 6.5 mm for cultivars BS2606, NS 6700 IPRO, NA 5909 RR, LANÇA; and 6.0, 6.5 and 7.0 mm for the BS IRGA 1642 IPRO cultivar). The following tests were conducted: germination, first germination count, shoot and root length, total seedling dry weight, seedling emergence, accelerated ageing and electrical conductivity. The results were subjected to analysis of variance, and the mean values were compared using Tukey’s test at 5% probability. The size classification of the soya bean seeds has no effect on the germination of the seeds that are produced. Higher seed vigour in the NA 5909 RR cultivar, determined by the seedling emergence test, and accelerated ageing in NS 6700 IPRO, were obtained from seeds produced by plants grown from seeds classified as a sieve size of 6.5 mm. For the other cultivars, the size classification of the seeds had no effect on the vigour of the produced seeds. field seasons 260 SOYTECH 670 590 164 i 58i6 used 20192020 2019 2020 2019/202 20202021 2021 2020/2021 blocks 5.5, 55 5 (5.5 60 6 0 6. 65 BS2606 70 7 7. cultivar. cultivar . cultivar) conducted count length weight conductivity variance Tukeys Tukey s probability 26 67 59 16 58i 2019202 201 202 2019/20 2020202 2020/202 5.5 (5.

Resumen La medición precisa y exacta de los fenómenos metacognitivos nunca ha sido más necesaria que en el acelerado mundo actual, en el que el alumno dispone de grandes cantidades de información. El MAI, Jr. (ver Sperling et al., 2002) es una medida de autoinforme de conciencia metacognitiva de 18 preguntas ampliamente utilizada. Sin embargo, esta medida no ha sido reexaminada en cuanto a validez de constructo y consistencia interna desde su inicio en 2002. En este documento se informa sobre los hallazgos de un estudio de 2 años en el que trabajamos para validar una versión abreviada del MAI, Jr. En el transcurso de 2 años, 601 estudiantes de 6.º a 8.º grado participaron en nuestro estudio. En cada año, los datos se examinaron mediante análisis factorial exploratorio con extracciones de factores comunes (factorización del eje principal [PAF]) y rotaciones oblicuas (promax). Los resultados de este estudio respaldan la validación de una escala abreviada de 7 ítems. Se discute por qué se prefieren medidas más cortas con validez de constructo y consistencia interna apropiadas.

Abstract Precise and accurate measurement of metacognitive phenomena has never been more necessary than in today’s fast-paced world in which vast quantities of information are readily available to the learner. The MAI, Jr. (see Sperling et al., 2002) is a widely used, 18-question, self-report measure of metacognitive awareness. However, this measure has not been re-examined for construct validity and internal consistency since its inception in 2002. In this manuscript we report on our findings of a 2-year study in which we worked to validate a shortened version of the MAI, Jr. Over the course of 2 years, 601 students in grades 6-8 participated in our study. In each year, data was examined using exploratory factor analysis with common factor extractions (principal axis factoring [PAF]) and oblique rotations (promax). The results of this study support the validation of a shortened, 7-item, scale. We discuss why shorter measures with appropriate construct validity and internal consistency are preferred.

Abstract Purpose: To adapt and validate in Sonora the scale to measure Attitudes towards Transgender People in University Students (EATU), which measures the inclusion of trans people in Higher Education Institutions (HEIS). Methodological design: Quantitative, cross-sectional and non-experimental study. 860 participants were selected among three HEIS, with non-probabilistic and intentional sampling. A 4-point Likert-type scale survey was applied that evaluates transinclusive attitudes. Reliability was obtained with Cronbach's alpha and McDonald's omega. For validity, the sample was randomly divided into two; In subsample 1, an Exploratory Factor Analysis (EFA) was carried out and in subsample 2, the model resulting from the EFA was tested using a Structural Equation Model (SEM). Results: The EFA yielded a final solution EATU of 32 items grouped into 3 dimensions called sensitivity, coexistence and cisexist stigma, with values that demonstrate validity and reliability. The SEM generated a model with indices of fitness in a final solution of 17 items and 3 correlated dimensions with acceptable coefficients. Research limitations: The measurement of transinclusion attitudes in a society where it has been documented that such construct is barely being developing, and the failure to collect demographic data on the sample about their religious beliefs. Findings: A measurement instrument on transinclusive attitudes for key social actors interested in promoting the inclusion of trans people, their human rights and substantive equality.

Resumen Objetivo: Adaptar y validar en el contexto sonorense la Escala para medir Actitudes hacia las Personas Transgénero en Estudiantes Universitarios (EATU) que mide la inclusión de personas trans en Instituciones de Educación Superior (IES). Diseño metodológico: Es un estudio cuantitativo, transversal y no experimental. De tres IES, participaron 860 personas seleccionadas con muestreo no probabilístico e intencional. Se aplicó una escala tipo Likert de 4 puntos que evalúa actitudes transincluyentes. La fiabilidad se obtuvo con alfa de Cronbach y omega de McDonald. Para la validez la muestra se dividió al azar en dos; en la submuestra 1 se llevó a cabo un Análisis Factorial Exploratorio (AFE) y en la submuestra 2 se probó el modelo resultante del AFE mediante un Modelo de Ecuaciones Estructurales (MEE). Resultados: El AFE arrojó una solución final de la EATU de 32 ítems agrupados en 3 dimensiones denominadas sensibilidad, convivencia y estigma cisexista, con valores de fiabilidad superiores a .90 y de cargas factoriales superiores a .36.

Resumen En el artículo se examina la relación entre la migración interna de NNA (niños, niñas y adolescentes) y la asistencia escolar en la entidad fronteriza de Baja California, México. Se combina el análisis de los microdatos del Censo de Población 2020 con la realización de entrevistas semiestructuradas a docentes que atendieron a este sector entre 2015 y 2022. Los NNA migrantes internos presentan desventajas en la asistencia escolar y las brechas aumentan si la migración es reciente y si los padres trabajan en la agricultura. Ser indígena es un factor protector de la asistencia escolar para los migrantes no recientes, pero de riesgo para los migrantes recientes; esto último coincide con las percepciones docentes. Estos señalan que existen barreras tanto socioeconómicas como del contexto educativo que limitan la inserción escolar de estos migrantes. El Estado tiene aún pendiente garantizar el derecho pleno a la educación de los migrantes internos.

Abstract The article examines the relationship between internal migration of children and adolescents and school enrollment in the border state of Baja California, Mexico. This research combines the analysis of the 2020 Population Census microdata and semi-structured interviews with teachers who served this sector between 2015 and 2022. Internal migrant children have disadvantages in school enrollment, and the gaps increase if the migration is recent, and if the parents work in agriculture. Being indigenous is a protective factor for school attendance among non-recent migrants, but a risk factor among recent migrants; the latter is consistent with teachers’ perceptions. Teachers point out that there are both socioeconomic and educational context barriers that limit the school integration of these migrants. The State still has to guarantee the full right to education for internal migrants.

Abstract Background: Urinary tract infections (UTIs) are the second most common cause of graft dysfunction, accounting for significant morbidity, and are associated with poor graft and patient survival. This study aimed to assess the association between post-renal transplant UTI and graft outcomes. Methods: We examined the effect of UTIs on graft outcomes in patients who underwent renal transplantation surgery between January 2010 and December 2022. The study population included 349 renal transplantations, of which 74 experienced 140 UTI events. Based on the number of UTI episodes, patients were categorized into three groups. Results: Of the 349 recipients, 275 (74.4%) had no UTI, 47 (18.8%) had non-recurrent UTIs (NR-UTIs), and 27 (6.8%) had recurrent UTIs (R-UTIs). Kaplan-Meier survival analysis showed that post-KT UTI status was a significant factor in graft survival, death-censored graft survival, and patient survival after a follow up of 5 years (log rank, P < 0.001). R-UTIs were associated with very poor graft survival and patient survival when compared with no UTI after a follow up of 5 years (hazard ratio [HR], 1.506; 95% confidence interval [CI], 1.233–1.840; P < 0.001 & HR, 1.529; 95% CI, 1.227–1.905; P = 0.001). R-UTIs were more likely to be associated with multi-drug resistant Gram-negative organisms (Klebsiella pneumonia or Escherichia coli) with resistance to nitrofurantoin (RR, 2.753; 95% CI, 1.257–6.032; P = 0.01) and carbapenem (RR, 2.064; 95% CI, 0.988–4.314; P = 0.05). Conclusion: Compared to no UTI, R-UTIs were associated to worse graft and patient outcomes after a follow-up of 5 years, whereas NR-UTIs were associated with poor graft and patient outcomes in the long term.

Resumo Histórico: Infecções do trato urinário (ITU) são a segunda causa mais comum de disfunção do enxerto, responsáveis por morbidade significativa, sendo associadas à baixa sobrevida do enxerto e paciente. O objetivo deste estudo foi avaliar associação entre ITU pós-transplante renal e desfechos do enxerto. Métodos: Examinamos o efeito das ITU nos desfechos do enxerto em pacientes submetidos ao transplante renal entre janeiro/2010 e dezembro/2022. A população do estudo incluiu 349 transplantes renais, dos quais 74 apresentaram 140 eventos de ITU. Baseado no número de episódios de ITU, categorizamos os pacientes em três grupos. Resultados: Dos 349 receptores, 275 (74,4%) não apresentaram ITU, 47 (18,8%) apresentaram ITU não recorrentes (ITU-NR) e 27 (6,8%) apresentaram ITU recorrentes (ITU-R). O método de Kaplan-Meier mostrou que o status da ITU pós-TR foi um fator significativo na sobrevida do enxerto, sobrevida do enxerto censurada para óbito e sobrevida do paciente após acompanhamento de 5 anos (log rank, P < 0,001). ITU-R foram associadas à sobrevida muito baixa do enxerto e sobrevida do paciente comparadas com nenhuma ITU após acompanhamento de 5 anos (razão de risco [RR], 1,506; IC 95%, 1,233–1,840; P < 0,001 & RR, 1,529; IC 95%, 1,227–1,905; P = 0,001). ITU-R apresentaram maior probabilidade de serem associadas a organismos Gram-negativos multirresistentes (Klebsiella pneumonia ou Escherichia coli) resistentes à nitrofurantoína (RR, 2,753; IC 95%, 1,257–6,032; P = 0,01) e carbapenem (RR, 2,064; IC 95%, 0,988–4,314; P = 0,05). Conclusão: Em comparação com ausência de ITU, ITU-R foram associadas a piores desfechos do enxerto e paciente após acompanhamento de 5 anos, enquanto ITU-NR foram associadas a piores desfechos do enxerto e paciente em longo prazo.

Abstract: Role overload in the family can be understood as a feeling of inability to complete duties that are the individual's responsibility, and this hardship occurs due to the accumulation of tasks in the family, which can cause discomfort. The aim of this study was to obtain valid evidence of Family Role Overload in Brazilian samples. Six hundred and forty Brazilian workers of both genders took part in the study. Confirmatory factor analyses showed that the Brazilian version remained single-factor and had six items. The multi-group analyses showed configural, metric, and scalar invariance between the groups divided in terms of gender and the existence or absence of children. The scale showed positive correlations with perceived family demands and family-work conflict and a negative correlation with perceived social support in the family. It was therefore concluded that the instrument had psychometric properties that recommend its use in future research.

Resumo: A sobrecarga de papeis na família pode ser compreendida como sentimento de incapacidade em concluir obrigações que são de responsabilidade do indivíduo, e essa dificuldade acontece devido ao acúmulo de tarefas na família, que podem trazer desconforto. O presente trabalho teve por objetivo obter evidências de validade da Sobrecarga de Papéis na Família em amostras brasileiras. Participaram do estudo 640 trabalhadores brasileiros, de ambos os gêneros. As análises fatoriais confirmatórias evidenciaram que a versão brasileira se manteve unifatorial e com seis itens. As análises multigrupo atestaram a invariância configural, métrica e escalar entre os grupos divididos em termos de gênero e sobre a presença ou ausência de filhos. A escala apresentou correlações positivas com demandas percebidas da família e conflito família-trabalho e correlação negativa com suporte social percebido na família. Concluiu-se, assim, que o instrumento apresentou propriedades psicométricas que recomendam seu uso em investigações futuras.
