In vitro embryo production (IVP) is a biotechnology applied to different species of domestic and wild mammals, in addition to humans. IVP includes the in vitro maturation of oocytes (IVM), in vitro fertilization of matured oocytes (IVF) and the in vitro culture of fertilized oocytes (IVC). In the IVM and IVC processes there is an increase in levels of reactive oxygen species (ROS) that generate higher levels of oxidative stress, which together with a deficient antioxidant system in in vitro conditions can affect these processes. Faced with this situation, the maturation media are supplemented with antioxidant compounds such as cysteamine (CYS), which is an amino thiol (SCH2CH2NH) of low molecular weight (77.1 g/mol), has its own antioxidant activity, promotes the transport of cysteine to the interior of the cell and favours the synthesis of glutathione (GSH). Research on the use of CYS i...

The research had as objective to know the teaching practice, regarding methodologies of teaching- learning strategies and the evaluation of the learnings that have been used in the technology race production and agricultural extension, where studying high school graduates of the north of Peru and the southern of Ecuador , and even the Galapagos Archipelago. This study was developed under the focus of teaching current alternative critical because priority was the analysis of the development of potentialities and capacities. (Cognitive and educational).The independent variables were: innovative strategies for teaching and learning; the mechanisms for evaluating the programming, and the dependent variable was the teaching practice. It is analyzed for the entire student population composed of 53 students, of whom 36.56 % were women and 63.44 % are men. The applied study was correlational, an...

La investigación tuvo como objetivo conocer la práctica docente, referente a metodologías de enseñanza-aprendizaje y a las estrategias de evaluación de los aprendizajes que se vienen utilizando en la carrera de Tecnología de Producción y Extensión Agropecuaria, donde estudian bachilleres del norte del Perú y sur del Ecuador, e inclusive de la provincia insular de Galápagos. Este estudio se desarrolló bajo el enfoque de la corriente pedagógica alternativa crítica porque se priorizó el análisis del desarrollo de potencialidades y capacidades (cognitivas y formativas).Las variables independientes fueron: las estrategias innovadoras de enseñanza – aprendizaje; los mecanismos de evaluación de los aprendizajes, y, la variable dependiente fue la práctica docente. Se analizó a toda la población estudiantil conformada por 53 estudiantes, de los cuales el 36,56% son mujeres y...
