    Efecto antioxidante y citoprotector de extractos de plantas con actividad antimicrobiana by Pérez Narváez, Oscar Alberto

    Published 2018
    “…Ningún extracto de los seleccionados por su buena actividad antimicrobiana y antioxidante presentó actividad hemolítica significativa, observándose el valor más alto de 3.1 ± 0.4 % en el de tallo de A. xalapensis a una concentración de 1,000 ppm; mientras que la capacidad citoprotectora de este extracto para eritrocitos humanos contra la hemólisis inducida por AAPH estuvo de manifiesto con un 98.5 ± 0.9 % a una concentración de 400 ppm, siendo a esa concentración la mayor actividad protectora que presentaron los extractos de hoja de A. xalapensis, y de hoja, tallo y raíz de T. cubense. …”

    Contenido de macro y micronutrientes en regosoles en áreas bajo manejo del matorral desértico micrófilo y rosetófilo. by Pérez Pérez, José Eduardo

    Published 2018
    “…According to the results obtained, it was found that the use of the aerating roller had beneficial effects due to the fact that the treatments showed better conditions in the layers from 0 to 15 cm deep, making the nutrients available to the plants, however, a cyclic use is recommended since over time the nutrients show a lower availability, as it was shown by the comparison of means between the control and the other aeration roller treatments, where it was found that the 9 application of this implement had better results in Ra11, which was one of the most recent applications in the study area.…”
