The Chavimochic irrigation project is one of the leading projects in Peru. In this project, irrigation water is derived from the Santa river to irrigate the valleys of Chao, Viru, and Moche, including desert zones between valleys. In this study, we aimed to characterise the Hass avocado and asparagus farms in desert areas of the Chavimochic irrigation project. Social, economic and environmental information was collected through structured surveys of 12 asparagus and 17 avocado farms. Four groups of asparagus farms and three groups of avocado farms were identified based on principal component and cluster analyses. Profitability of the avocado crop was higher than that of the asparagus crop, and irrigation caused more significant variability in the crop yield of avocado than that of asparagus. From the social perspective, the income of farm personnel was related to the level of education, ...

Periodontal diseases after dental caries are the most prevalent in the dental health is concerned. The gingivitis and periodontitis are the result of the presence of bacteria and their products capable of altering the tissue and the host response. Studies on action of Camellia sinensis (green tea) on microorganisms of periodontal disease, demonstrates the beneficial effects of this product and the application potential in different areas. Therefore the purpose of the study was to determine the in vivo effectiveness of a gel made from carboximetilcelulosa and alcoholic extract of green tea, and in vitro on microorganisms associated with periodontal disease: P. loeschi, P.anaerobius and Capnocytophaga. The results show the presence of halos of inhibition of green tea extract at concentrations of 100 %, 75 %, 50 % and 25 %, the gel was observed only action on the site of contact, no halo. R...

Las enfermedades periodontales después de la caries dental, son los problemas más prevalentes en lo que a salud bucal se refiere. La gingivits y la periodontitis son resultados de la presencia de las bacterias y sus productos capaces de alterar los tejidos así como de la respuesta del hospedero. Diversos estudios se han desarrollado utilizando productos naturales en el país, por ejemplo, la uña de gato, muña, propóleo, coca, el té verde comprobándose su acción antimicrobiana y en este ultimo caso también acción anticancerígena. El propósito del estudio fue determinar la efectividad in vivo de un gel elaborado con carboximetilceluloda y extracto alcohólico de té verde, é in vitro sobre microorganismos relacionados con la enfermedad periodontal como: Prevotella loeschi, Peptostreptococcus anaerobius y Capnocytophaga.Los resultados muestran la presencia de halos de inhibici...
