SbstractPolyphenolic resol resins were obtained from an ethanolic extraction of green plantain peels (Musa paradisiaca) grown in Colombia. A synthesis was then performed by polycondensation in an alkaline pH solution in order to perform research on phenolic resin production with high mechanical performance. The polymers were characterized by DSC and TGA analyses and the resins showed a melting point of 94 °C and the typical properties of resol resins. Moreover, the synthesis was controlled using the infrared technique (FTIR) where different organic functional groups present in the polymers obtained are observed. The obtained resins were used as heavy metal adsorbents in which the content of those toxic agents is measured by Atomic Absorption Analysis (AA) indicating that these resins have a high retention affinity to Pb +2 , Ni +2 and Cr +3 (79.01%, 98.48%, 94.14%, respectively) as determined by Freundlich isotherms.

ResumenObjetivo. Evaluar el efecto del extracto acuoso de Tropaeolum tuberosum "mashua" sobre el deterioro de la memoria y la lipoperoxidación inducida por fluoxetina en hígado en Rattus rattus var. albinus ooferectomizadas. Materiales y métodos. Estudio experimental. Se usaron 29 animales de experimentación intervenidos por seis semanas divididos en cinco grupos: Blanco (n=5), que no recibió ninguna intervención; Control (n=6), ratas con ooforectomía bilateral; Patrón (n=6), ratas ooforectomizadas a las cuales se les administró 20 mg/kg por vía oral de una solución de 0,15 % de fluoxetina (inductor de lipoperoxidación) por tres semanas, una vez al día; y finalmente los grupos Problema I (n=6) y II (n=6) que recibieron la misma intervención del grupo Patrón por tres semanas y, posteriormente, se les administró el extracto de Tropaeolum tuberosum "mashua" a una dosis de 1 g/kg en concentraciones de 10 y 20%. Resultados. Se encontró diferencias significativas en el grupo que recibió el extracto de Tropaeolum tuberosum al 10% en comparación con el que recibió solo fluoxetina (p=0,002). No se encontraron diferencias significativas entre grupos ni intra grupo en la evaluación sobre el deterioro de la memoria. Conclusión. Se observa una mejora en los estilos de vida después de la intervención de Reforma de Vida, principalmente en las dimensiones de Familia, Introspección y Nutrición/Alimentación en los adultos mayores miembros de los Círculos de Salud de los distritos de Alto Selva Alegre y Cayma en Arequipa, en el año 2016.

AbstractObjective. The objective of this research was to demonstrate the effect of aqueous extract of Tropaeolum tuberosum "Mashua" on memory impairment and lipid peroxidation induced liver fluoxetine and Rattus rattus var. albinus ooforectomizadas. Material and methods. Experimental research. This research was conducted in five groups, making a total of 29 specimens of the species females, in which only 24 of them were induced them to a process of menopause (ovariectomy). The groups were divided into: naïve, control which were administered fluoxetine 20 mg/kg at a concentration of 0.15 % for three initial weeks, problem 1 and 2, at a dose of 1 g / Kg at a concentration of 10 % and 2 g/kg at 20% concentration respectively. Results. Significant differences were found in the group receiving the 10%(1 g/kg. Tropaeolum tuberosum extract compared to that rece...
