Mycobacterium tuberculosis (Mtb) sigue siendo uno de los patógenos más mortales a nivel mundial, a pesar de ser una enfermedad prevenible. La tuberculosis (TB) se trata con una combinación de cuatro medicamentos antituberculosos de primera línea: rifampicina (RIF), isoniacida, pirazinamida y etambutol, para cepas sensibles a los medicamentos. Entre estos, la RIF es uno de los agentes más potentes para controlar la enfermedad. Sin embargo, la resistencia a la RIF conlleva la aparición de casos de TB resistente a la RIF (RR-TB) o multidrogo resistente (MDR-TB). El mecanismo principal de resistencia implica mutaciones en el gen rpoB, que es responsable de aproximadamente el 95% de los casos. No obstante, todavía se están identificando otros mecanismos moleculares y condiciones que podrían contribuir a la propagación de las poblaciones RR-TB y MDR-TB. Esta investigación doctoral s...

The relationship between executive functions (EF), creative personality, and academic performance in Argentine university students was examined. A total of 248 students (M = 22.97 years, SD = 4.43) from various Argentine provinces participated. The Adult Executive Functioning Inventory (ADEXI), the Cognitive Flexibility Scale, the Creative Behavior Scale (ECC), and the Creative Personality Scale (EPC) were used, along with academic performance data and sociodemographic information. Data were collected online through Google Forms and analyzed using Spearman correlations and mediation analysis with robust Maximum Likelihood estimator and Bootstrap. Cognitive flexibility exhibited the most robust correlation with grade point average (r = .281, p < .001), followed by working memory difficulties (r = -.234, p < .001). Creative personality correlated positively with grade point average (...

Intelligence is a construct of notable impact in our sociocultural context, related to a wide range of conceptual and operational definitions which originate positions that highlights cognitive and abstract elements and emotional and social skills, as well was perspectives that are focused on processes underlying the intelligent performance, such as in the case of executive functions (EFs), which are configured as cognitive processes that make it possible the self-regulation (Miyake & Friedman, 2012). Similarly, there are approaches that give intelligence a relevant and predictive role of school performance, an aspect strengthened by the psychometric perspective, where the concept of intelligence has been closely linked to learning. In this line, we also find the classical perspective of crystallized Intelligence of Cattell (1943), which refers to the knowledge acquired through educa...

This study describes the axiological model of the technological package as a pre-patentable foundation of innovation, designed to articulate the value dimensions underpinning validation, transfer, and potential impact on preventive health. A descriptive, non-experimental study with a qualitative–analytical approach was conducted through structured documentary review and hermeneutic content analysis. The results present a systemic model that integrates ethical, technical, and social principles, structuring the innovation process from need identification to product commercialization and maintenance. This framework demonstrates that axiological coherence provides the technical robustness, sustainability, and social relevance required for responsible biotechnological innovation. The study concludes that the axiological foundation enables the transformation of scientific knowledge into pre-...

In Mexico, a high percentage of young people experience symptoms of generalized anxiety, which are associated with difficulties in executive functions (EF). However, previous studies have shown inconsistent results, as they often rely solely on either objective or subjective measures. Therefore, this study focused on analyzing the relationship between generalized anxiety and EF using both a neuropsychological battery and a self-report questionnaire, in order to provide a more comprehensive understanding of cognitive functioning in adolescents. A quantitative, non-experimental, cross-sectional, correlational, and explanatory design was employed. The sample consisted of 96 adolescents between 12 and 15 years old from the state of Puebla, Mexico. A total of 10.41% of participants presented severe symptoms of generalized anxiety. A significant relationship was found between anxiety and one o...

In order to determine whether family functioning predicts the level of resilience in parents facing the impact of the COVID-19 pandemic, a predictive and cross-sectional study was conducted on a sample of 183 parents from the department of La Libertad, who were selected under a non-probabilistic purposive sampling. Two instruments were used to collect data: Cohesion and Family Adaptability Evaluation Scale (CESF) and the Brief Resilient Coping Scale (BRC). Based on a linear regression analysis, an adequate model fit is observed (F-test = 35.924, p < .001), where, family functioning (β = .407, p < .05) is a variable that significantly predicts resilience (adjusted R2 = .161). Also, the t-values of the beta regression coefficients of the predictor variable are highly significant (p < .01). In conclusion, the level of family functioning predicts the degree of resilient coping in p...
