En el contexto de Chile, Ã©sta se caracteriza por ser principalmente corte tradicional con transferencia unidireccional de la informaciÃ³n. Actualmente se propone lograr un aprendizaje mÃ¡s significativo, con la ayuda de modelos como Aula invertida. El objetivo de este estudio es comparar el rendimiento acadÃ©mico entre el modelo tradicional (MT) y Aula invertida (AI). Se intervinieron 2 cursos de 1Â° aÃ±o, de las carreras de NutriciÃ³n y OdontologÃa aÃ±o 2022 de la Universidad de La Frontera, en los que se aplicÃ³ MT y AI, comparando el rendimiento con un test post clase en NutriciÃ³n, y un trabajo grupal en OdontologÃa. Se realizaron anÃ¡lisis estadÃsticos descriptivos y pruebas que compararon las notas obtenidas. En uno de los grupos se segmentaron los estudiantes por rendimiento para analizar cÃ³mo afecta cada modelo dependiendo del tipo de estudiante. Se obtuvo mejor promedio post test con AI en NutriciÃ³n; 4,9 Â±1,3, en contraste con un promedio de 4,2 Â±1,3 para MT (escala 1,0 a 7,0). La prueba T de Student arrojÃ³ diferencias estadÃsticamente significativas (p<0,05), y el test ANOVA de bloques dio cuenta de diferencias en los resultados si se utiliza AI, con mejores rendimientos en tal caso. Para OdontologÃa no hubo diferencias significativas (p>0,05) en las calificaciones de los trabajos grupales con MT y AI. Es imperante actualizar la enseÃ±anza de la AnatomÃa en favor de lograr un aprendizaje significativo, mediado por el trabajo de pares y el estudiante como protagonista que propone AI, que a su vez beneficia a aquellas personas con rendimientos mÃ¡s bajos al comienzo.","PeriodicalId":14023,"journal":{"name":"International Journal of Morphology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136127871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

La imposibilidad de trabajar con material orgÃ¡nico demandÃ³ que al menos las imÃ¡genes a utilizar fueran de alta calidad. Para lo anterior, se usaron fotografÃas de disecciones del laboratorio de anatomÃa, mÃ¡s digitalizaciones de estructuras humanas de nuestro laboratorio en formato 3D disponibles en la plataforma web https://anatomiahumana3d.com. No obstante lo anterior, se detectÃ³ cierto grado de desidia por parte de los estudiantes y escasa participaciÃ³n en las actividades prÃ¡cticas. Para resolver esto se implementÃ³ una modalidad de Aprendizaje Activo, especÃficamente de Aula Invertida, con el fin de que sea el propio estudiante quien genere su conocimiento. Una vez terminado el proceso de enseÃ±anza aprendizaje bajo la nueva modalidad, se realizÃ³ un estudio descriptivo, a fin de detectar falencias y proponer mejoras respecto a la metodologÃa aplicada. Los resultados arrojaron un nivel de satisfacciÃ³n por sobre el 80 %, en tanto, que solo el 5 % de los estudiantes contestÃ³ como aceptable las diferentes dimensiones evaluadas, demostrando como el sistema de aula inversa fue bien recibida por los estudiantes.

This study aimed to analyze the activation of plasma cells and the correlation between the infiltration of B and T lymphocytes with the degree of malignancy or Gleason grade in human prostate biopsies diagnosed with cancer. Prostate cancer biopsies were obtained from the Clinical Hospital of Universidad de Chile (n=70), according to the bioethical norms of the institution. Histological sections of 5Âµm thickness were processed for immunohistochemistry with primary antibodies against BL and total TL (HRP/DAB). Recognition and quantification were performed under a Leica DM750 optical microscope. Microsoft Excel and GraphPad software were used for the statistical study. Correlation coefficient (Pearson) and mean comparison tests (Kruskal-Wallis and Dunn) and pâ¤ 0.05 were developed. B and T lymphocyte populations were inversely interregulated in prostate cancer (Gleason) (r= -0.46). Their relationship with Gleason grade is variable according to lymphocyte type (LB vs. Gleason r= -0.0.47 and LT vs. Gleason r= -0.21). Histological diagnosis of prostate cancer correlates with a predominance of LT. The malignancy of the pathology correlates with a predominance of LTs, according to the Gleason grade. The increased knowledge of B and T lymphocyte infiltration and plasma cell activation could be used to better target clinical trials on treatments based on immune system responses. Immunotherapy could be a new paradigm to apply better antitumor therapy strategies.","PeriodicalId":14023,"journal":{"name":"International Journal of Morphology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136127510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results were compared between right and left and between both sexes. The L5 has the longest AVBH and the shortest PVBH in both sexes, it also, had the shortest and widest pedicle in both males and females. ratio of the AVBH to PVBH showed progressive increase in both sexes from T11 to L5. Similarly, the VBW increased progressively from the top to the bottom in both sexes, but it was significantly different between both sexes. The L1 was the most cranially oriented vertebrae in males while the L2 showed the most cranial orientation in females. Both sexes L5 was the most caudally oriented vertebrae. This study provides a database for vertebral morphometrics in the Jordanian population, there are slight differences between the right and left side in the upper studied vertebrae (T11-L2) and some measurement showed significant differences between males and females. These findings need to be taken into consideration when inserting pedicle screws.","PeriodicalId":14023,"journal":{"name":"International Journal of Morphology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136127715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
