Capítulo 5. Belle épreuve
Authors: Bernal María del Mar
Published: October 2024

Philippe Burty acuñó el término belle épreuve en el prefacio al álbum L’Eau-forte de la Société des aquafortistes en 1875. El capítulo sexto actualiza este concepto decimonónico estableciéndolo como punto de partida para la estampación artística. Burty mantuvo que la belleza de la estampa «aparte del sentimiento del artista que la ha concebido, está influida también por la habilidad del impresor que la ha hecho nacer y el gusto del aficionado que la sabe distinguir y la elige». En poco tiempo la belle épreuve supuso la distinción del grabado artístico con las estampas frías y reproductivas que durante muchos años fueron la versión oficial del grabado. Este pequeño texto es una oda a la estampación y a la capacidad de esta disciplina grabado para sensibilizar al espectador.

The traditional method of problem-solving, known as hard computing, is limited in its ability to handle modern digital technology and real-world problems accurately. Soft computing, a newer paradigm, offers a more versatile approach by utilizing multi-valued logic and human knowledge to solve complex, nonlinear problems efficiently. Unlike hard computing, soft computing can handle imprecise data and uncertainty effectively. This methodology has been successfully applied across various sectors, including scientific, industrial, and medical fields, providing more accurate results. Soft computing is good for its contributions to revolutionizing problem-solving techniques, being tolerant of imprecision, uncertainty, and linguistic variables, and offering approximate solutions to intricate problems.

Published: October 2024

The search for an eco-freindly larvicide suitable for vector control requires a budget and considerable time to carry out experiments. Fortunately, the use of QSAR modeling allows the prediction of larvicidal activity of structurally diverse chemicals against mosquitoes in a way quick and costless. This approach can be helpful to study for making biolarvicide with highest ability to destroy mosquito larvae. We propose a QSAR model using two different statistical methods, multiple linear regression (MLR) and Support vector machine (SVM) for predicting the larvicidal activity of 30 compounds of essential oil (EOs) isolated from the root of Asarum heterotropoides against Culex pipiens pallens. A model with four theoretical descriptors derived from Dragon software was developed applying the genetic algorithm (GA)-variable subset selection (VSS) procedure. The statistical parameters, R2 = 0.9716, Q2LOO = 0.9595, s = 0.1690 of the model developed by MLR showed a good predictive capability for log LC50 values. The comparison between the results of SVM and MLR models showed that the SVM model present a good alternative to construct a QSAR model for the prediction of the larvicidal activity.

Published: October 2024

The global demand for essential oils is expanding as a result of their numerous applications and increasing consumer exposure in the international market. Essential oils (EOs) are mixtures of volatile compounds including, but not limited to, phenolics, esters, ketones, terpenes, alcohols, and amides. The majority of EOs have excellent antioxidant, antibacterial, and functional activities. These natural products have conquered space in the food, drug, and cosmetic commercial arena. Unfortunately, like many lipophilic and aromatic active substances, EO presents some drawbacks such as low water solubility, strong organoleptic characteristics, low stability, and limited administration routes, which confines their Industrial use. EOs can be nanoencapsulated to increase their persistence, and bioavailability in the biological process by employing the optimum encapsulation polymers. Additionally, these particles are capable of controlling the release of the EOs promoting a prolonged preservative effect in cosmetics and foods, as well as a potential advantage for pharmaceutical dosage forms. The current research focuses on the essential features of EOs as well as their encapsulation methods. Furthermore, the potential applications of applying nanoencapsulated essential oils in the healthcare field were addressed.

Published: October 2024

Objective: The infection of respiratory tract pathogens may extend the inpatient days of hospitalized patients. However, the excessive usage of antibiotics leads to pathogens which acquired resistance. Hence, the quick and precision detection of the types and antibiotic sensitivity of causative agents for hospitalized patients is essential. Nowadays, the diagnostic approaches include standard culture, molecular typing and antigen detection. However, the current analytics is limited by low sensitivity and long turnaround times. In this study, we utilized the BioFire FilmArray pneumonia panel (PN panel) to compare the performance with standard testes in hospitalized patients. Method: We analyzed the targeted pathogens and antimicrobial resistance markers by PN panel from hospitalized patients. Subsequently, we compared the detection results with those of culture methods and antibiotics susceptibility testing. Conclusion: The endotracheal aspirates and sputum specimens came from 806 hospitalized patients, 476 patients (59%) were positive by PN panel assay and multiple pathogens were detected by PN panel in 241 patients (29.9%). The panel detected A. calcoaceticus-baumannii complex and P. aeruginosa most frequently, followed by K. pneumoniae group, S. aureus and E. coil. We further analyzed 145 patients with the expression of antimicrobial resistance markers. The percentage of the pathogens were detected both in PN panel assay and standard culture was 51.7% (75/145). Moreover, the antibiotics susceptibility testing from 65 patients (44.8%) were actually concordance with antimicrobial resistance gene expression. Besides, the numbers of pathogens from PN panel in 102 patients (70.3%) were higher than from standard culture. The more detected pathogens from PN panel may remind the further investigating antibiotic sensitivity and provide the considerable prescription of antibiotics.

Published: October 2024

Objetivo: Infecções pulmonares e intra-abdominais em pacientes hospitalizados estão associadas à maior morbimortalidade, com o desfecho clínico variando conforme o manejo hemodinâmico e a antibioticoterapia adequada. Tais infecções estão entre as principais causas de morte por doenças infecciosas nos países desenvolvidos devido à dificuldade de se estabelecer o agente etiológico, considerando-se a grande diversidade de agentes possíveis. Dessa forma, este trabalho tem o objetivo de detalhar o perfil microbiológico presente nas amostras de líquido pleural e peritoneal de um laboratório de grande porte. Método: O estudo é do tipo transversal e retrospectivo, feito a partir do levantamento de 720 amostras de líquido pleural e peritoneal coletadas em diferentes hospitais. A detecção dos patógenos foi realizada pelo método de cultura realizado em um laboratório particular, no período de janeiro de 2020 a dezembro de 2022. Conclusão: A análise dos dados revela a presença de diferentes tipos de bactérias nos líquidos pleural e peritoneal, bem como a distribuição dos resultados entre os dois locais de coleta. Dentre os resultados analisados, a cultura foi positiva em 16 amostras, tanto de líquidos pleurais como de líquidos peritoneais. Quanto ao perfil microbiológico, Staphylococcus aureus foi a bactéria mais presente (28%), seguida de Pseudomonas aeruginosa (21%) e Klebsiella pneumoniae (18%). O Staphylococcus aureus foi identificado em nove casos de líquido pleural, sugerindo que essa bactéria pode desempenhar um papel importante nas infecções pleurais. No entanto, não foram encontradas ocorrências no líquido peritoneal. Esses resultados destacam a diversidade bacteriana presente nos líquidos pleural e peritoneal, mostrando associações específicas com cada local. É fundamental considerar esses dados junto a informações clínicas adicionais para estabelecer diagnósticos precisos e desenvolver estratégias terapêuticas adequadas.

Second-generation ethanol production is a worldwide applicable technology with the potential to replace fossil fuels and contribute to sustainability. The incorporation of second-generation ethanol production in Brazilian biorefineries, besides the technological advantages, adds to the abundance of feedstock derived from the sugar and alcohol industry itself. However, developing yeast strains that resist the inhibitory conditions of the new substrate, potentiated by cellular recycling, is extremely necessary. The aim of the present work was to develop yeast strains by hybridization and selective pressure techniques, with multi-tolerant profile for the fed-batch fermentation process using a mixture of molasses and bagasse hydrolysate as substrate. Therefore, the mass crossing technique was carried out involving five strains of Saccharomyces cerevisiae, previously selected, for demonstrating high tolerance to fermentation from mixed-must composed of lignocellulosic hydrolysate and sugarcane molasses. The culture resulting from the mass mating was followed by a selective pressure during 51 generations, generating enrichment of more tolerant strains. Employing microplate growth evaluation (optical density [DO] 600 nm), ten evolved isolates were selected, which were submitted to lab scale fermentation, simulating industrial conditions to the maximum. In the end, it was possible to highlight a lineage (C8E1-13T) presenting trehalose reserve content significantly higher than the other lineages evaluated, thus demonstrating the generation of an improved phenotype.

Aims: To identify effects of educational material among children with clubfoot during bracing stage of treatment by Ponseti method.

Methods: This study was a quantitative type quasi-experimental research design. Actually, it was an experiment among specific groups and usual groups. Exercises applied with educational material to the material group or experiment group and only usual exercises applied to the non-material group or the control group. A pre-test (before exercises provided by educational material) and post-test (after exercises provided by educational material) was administered with each subject of both groups to compare the effects on children with clubfoot during bracing stage of treatment by Ponseti method.

Results: The mean Pirani score before providing exercises with educational material for right feet among the clubfoot babies were 0.56 ± 0.33 (material group) and after providing exercises with educational material for right feet among the clubfoot babies were 0.43 ± 0.41 (material group). Statistically it was found highly significant (t = 2.99, p greater 0.0003). So, it was concluded that exercises with educational material had significant influence on Pirani score reduction for right feet among the clubfoot babies. The mean Pirani score before providing usual exercises for left feet among the clubfoot babies were 0.5 ± 0.15 (non-material group) and after providing usual exercises for left feet among the clubfoot babies were 0.53 ± 0.48 (non-material group). Statistically it was found significant (t = –0.059, p greater 0.056). So, it was concluded that usual exercises without educational material had influence on Pirani score increased for left feet among the clubfoot babies.

Conclusion: The modern treatment of clubfoot is Ponseti method which is very effective, outcome oriented, and less invasive surgical procedure. This study was concluded that exercises with educational material had significant influence on Pirani score reduction among the children with club foot. So, there was significant importance of exercises with educational material rather than usual exercises by verbal instructions.

Fecal zonulin as a prognostic marker of atopic march in children with food allergy
Authors: Prikhodchenko N. G. , Shumatova T. A. , Kovalenko D. V.
Published: October 2024

Introduction. The onset of allergic diseases most often occurs in early childhood with the onset of food allergies, which can subsequently lead to the implementation of the atopic march. Increased intestinal permeability with high production of zonulin, the main moderator of intestinal tight junctions, can be an important link in the development of comorbid allergic diseases.

Material and methods. In order to study the significance of fecal zonulin as a marker for predicting the atopic march in children with food allergy, a cross-sectional retrospective study was conducted on 73 children aged 5 years who were diagnosed with food allergy (FA) to cow’s milk proteins in the first year of life. In all children, when the diagnosis was made in the first year of life, the content of zonulin in feces was determined using the ELISA method.

Results. As a result of dynamic observation, all children with food allergy were divided into 2 groups: the first group consisted of children with food allergy who developed allergic rhinitis and/or bronchial asthma within 5 years (group I, n = 39), group 2 consisted of 34 children with food allergy who did not implement the atopic march within 5 years of observation (group II, n = 34). Our study showed statistically significant differences in the fecal zonulin level in the first year of life: group I Me = 2.39 ng/ml (Q1-Q3: 1.78–2.65 ng/ml), group II Me = 1.85 ng/ml (Q1-Q3: 0.49–0.91 ng/ml), p = 0.034. Strong direct correlations were found (Spearman correlation coefficient S = 0.681 (p < 0.05)) between the zonulin level in feces at the onset of the disease and the development of allergic rhinitis and/or bronchial asthma up to 5 years of age, the data were confirmed by comparing the areas under the curves during ROC analysis, AUC in the study of fecal zonulin as a prognostic marker of the risk of atopic march in children is 0.887, the optimal threshold (cutoff point) is 1.94 ng/ml.

Conclusions. Fecal zonulin level in children with food allergy can be an effective prognostic marker of atopic march development, its values in feces above 1.94 ng/ml allow us to predict with a high degree of probability the risk of atopic march development  in children with food allergy to cow’s milk proteins within 5 years

Authors: Diaz Frank M. , Clark Zachary
Published: October 2024

We examined the influence of gender, age, and death of loved ones due to COVID-19, race/ethnicity, mode of instruction (hybrid, in-person, etc.), general religiosity, dispositional spirituality, and self-compassion among kindergarten through 12th-grade (K–12) music educators (N  = 637) in order to assess how these factors impacted their mental health approximately 1 year after the onset of the COVID-19 pandemic. Our findings indicate a weak to moderate influence on mental health attributable to religiosity and spirituality, with feelings of connection to a higher power predicting better mental health while feelings of connection to other human beings and nature predicting the opposite. Additionally, there was a strong and statistically significant relationship between self-compassion and positive mental health, accounting for between a .87 to 1.09 decrease in stress, depression, and anxiety among participants based on one-unit increases in self-compassion. We discuss implications for music education research as well as preservice and in-service professional development based on these findings.

Authors: Roseth Nicholas E.
Published: October 2024

Kindergarten through 12th-grade (K–12) music teachers spend much of their professional lives occupying physical workspaces like classrooms and offices. Given that teachers occupy these spaces for extended periods of time, the impact of these spaces on teacher well-being should be considered. This exploratory survey study examined the relationships between K–12 music teachers’ workplace well-being and perceptions of the physical classroom spaces. A questionnaire was completed by 484 music teachers who were members of the National Association for Music Education. The questionnaire included the Workplace PERMA Profiler (a measure of workplace well-being) and the Structural, Physical, and Campus Environment Survey (a measure of teachers’ perceptions of their classrooms). Higher levels of well-being were positively correlated with favorable perceptions of classroom space. Scale and aesthetics, the visual environment, and spatial environment elements were the strongest predictors of well-being. Taking statistical and textual data together, specific features including windows, good natural light, quality and controllable lighting, aesthetically pleasant (e.g., decorations and colors) rooms, ample space and storage, comfortable temperatures, good organization, and control over the classroom space had the largest positive impact on well-being among the participating teachers.

Authors: Ge Siqing
Published: October 2024

Three years after the outbreak, the year 2023 has officially entered the post-epidemic era. The aviation industry, which was severely hit by the epidemic, is gradually recovering. This article describes the current situation of the aviation industry after the epidemic, taking the Civil Aviation of China (CAAC) as the subject of the study, and analyses the problems it faces: the number of international flights has been slow to recover and unable to meet market demand; the financial crisis has been highlighted due to severe losses; supply chain shortages have prevented the timely delivery of aircraft; and the rapid increase in environmental pollution has led to a serious decarbonization situation. Potential solutions were also proposed for these four problems. These include increasing the number of flights through government consultation and communication, increasing revenue streams and reducing unnecessary spending to tide over the financial crisis, achieving supply chain resilience to avoid the obstacles posed by supply chain shortages, and developing new sustainable technologies for aviation to reduce air pollution.
