Biological characteristics of a subpopulation of cancer stem cells from two triple-negative breast tumour cell lines, HELIYON,
Introduction: The lack of knowledge about denture hygiene can negatively affect their maintenance. On the other hand, good oral hygiene can reduce the chances of plaque accumulation. Objetive: To determine if there is a relationship between knowledge of hygiene and denture maintenance. Material and Methods: A questionnaire was applied to 67 patients who wore partial and/or total removable prostheses daily to evaluate their knowledge of denture hygiene. For the evaluation of denture maintenance, clinical inspection of the removable prosthesis was carried out using the Vigild criterion to observe the amount of plaque that was adhered to it. Data were statistically processed with Spearman's correlation test to determine the relationship between hygiene knowledge and denture maintenance. Results: The patients presented a medium (37.3%) and low (56.7%) denture hygiene knowledge; and fair (68.7%) and poor (11.9%) maintenance of their prosthesis. There is a statistically significant relationship between hygiene knowledge and denture maintenance (p<0.001). Conclusion: There is little knowledge of denture hygiene. This level of knowledge has a statistically significant relationship with the maintenance of the prostheses.
Con la presente investigación se determinó la contribución del Flipped classroom en el aprendizaje de la biología celular con razonamiento crítico. Una estrategia activa que promueve el desarrollo de nuevas competencias profesionales y cambios de paradigmas del docente en su práctica pedagógica. El abordaje investigativo realizado ha sido cuasi experimental con enfoque cuantitativo y analítico en 54 estudiantes sometidos a 08 sesiones virtuales como presenciales integrando el modelo Flipped classroom y a una prueba objetiva de 20 ítems, como instrumento de recolección de datos. Instrumento validado por cinco especialistas del área y un grupo piloto de estudiantes, alcanzando un coeficiente de confiabilidad alfa de Cronbach de 0,678. Los resultados obtenidos luego de aplicar esta estrategia didáctica, revela una disminución del 68% al 28% de estudiantes en nivel no logrado; un incremento del 32% al 64% en un nivel en proceso, y desde un 0% al 8%. en un nivel destacado. Hallazgos que luego de ser estimados con los estadísticos de pruebas descriptiva con p ˂ 0,05; y de pruebas inferenciales como la prueba de Wilcoxon y Mann Whitney con significancia estadística (p=0,003) y confiabilidad de 0,678), en muestras relacionadas en muestras y no relacionadas respectivamente, fundamenta que incorporar Flipped classroom o “clase invertida” fortalece las dimensiones del aprendizaje: conocer, comprender, aplicar y analizar, de las asignaturas de ciencias básicas, que generan rechazo en el estudiante de medicina que ingresan a la universidad.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
