Evaluación de hortalizas de frutos y ornamentales regados con agua residual tratada de la ciudad de Calama y agua del río Loa cultivado bajo invernadero pasivo en dos formatos de cultivos sin suelo - sacos de fibra de coco y canaletas con mezcla de turba + perlita = 50:50. Se utilizó para la producción de agua de riego un filtro de carbón activado...
The abandonment of ancestral techniques and the incorporation of new technologies in the production systems for the cultivation of quinoa has resulted in overexploitation of soils, a loss of fertility, water imbalance, a loss of native vegetation cover in plain land areas, and other negative effects on the southern Altiplano agricultural sustainabl...
The information contained in this manual comes from the results obtained from the execution of the study "Diagnosis of Intra-Farm Water Treatment for Irrigation in Camarones" - Code BIP 40014086-0, financed by the National Irrigation Commission.
The study presents the technological actions implemented for the abatement of salts, boron and arsenic...
Throughout evolution, plants have developed different strategies of responses and adaptations that allow them to survive in different conditions of abiotic stress. Aloe vera (L.) Burm.f. is a succulent CAM plant that can grow in warm, semi-arid, and arid regions. Here, we tested the effects of preconditioning treatments of water availability (100,...
Determination of plant species to promote the development and scaling of crops with high potential and feasibility of adaptability to desert conditions.
Most of the advances for the introduction of new crops in areas with extreme conditions of abiotic stress are the product of public-private efforts to contribute to the productive diversification...
RESILENCE IN PROSOPIS: PHYSIOLOGICAL ADAPTATIONS BEFORE CLIMATE CHANGE
Delatorre-Herrera, J; Arenas, J. and Delatorre- Castillo. J.P
Faculty of Renewable Natural Resources / Arturo Prat University, Iquique, Chile
FAO (2016), the main climatic implications in the dry forests in Piura, will be temperature increases between 0.4 to 1.2 ° C, changes in...
Abstract
Between October 2017 and July 2019, researchers from the Desert Agriculture area of the Faculty of Renewable Natural Resources of the Arturo Prat University, executed the project “Diversification of the agricultural offer in the Province of Tamarugal through the introduction of the crop of Saffron (Crocus sativus L) in the Chilean desert”,...
Water extraction from the underground aquifers of the Pampa del Tamarugal (Atacama Desert, Chile) reduced the growing area of Prosopis tamarugo, a strict phreatic species endemic to northern Chile. The objective of this work was to evaluate the effect of various architectural and morpho-physiological traits adjustment of P. tamarugo subjected to th...
Northern Chile has scarce water resources due to the Atacama Desert. Thus, water obtained from The Andes range has great interest. This study analyzes the effect of different amounts of irrigation water on gas exchange, seed yield, biomass and water use efficiency in two chia (Salvia hispanica L.) phenotypes, white and black. We performed measureme...
Resumen Introducción: el cáncer de colon es uno de los tumores digestivos más frecuen-tes y mortales. Sus complicaciones pueden ser variadas y en ocasiones tener presentaciones raras o poco frecuentes. Se presenta el caso de un paciente con un absceso de pared abdominal secundario a la perforación de un tumor en colon transverso. Caso clínico: Masc...
Chia (Salvia hispanica L.) is a species with seeds that have
high essential fatty acid content, which has encouraged
increased crop production worldwide. However, the
expansion of chia is limited because it is a photoperiodsensitive
plant adapted to areas without cold. The objective
of the present study was to determine the effect of different
clim...
The occurrence of frost during the winter months is among the most limiting factors for plant growth and establishment in arid climates. In this context, we evaluated the variation in the physiological parameters in two populations of Prosopis burkartii—a species that is listed as critically endangered —during the frost-prone winter periods of 2012...

APOE gene variants may contribute to the risk of chronic kidney disease. Our aim was to determine whether the common APOE-ε2/ε3/ε4 polymorphism is associated with a reduced estimated glomerular filtration rate (eGFR) in the RENASTUR population, a cohort of elderly individuals from the region Asturias (northern Spain).
A total of 743 Spanish Caucasi...
The MYH9 gene encodes a protein that is expressed in the kidney glomerular podocytes. MYH9 single nucleotide polymorphisms (SNPs) have been linked to the risk for chronic kidney disease (CKD) and end stage renal disease. Our aim was to determine whether MYH9 SNPs were associated with renal disease in Spanish Caucasians. The RENASTUR cohort consiste...
RESUMEN En la década de los 90, se presentó una escasez de la quinua para la población y los mercados chilenos, sobre todo en la región de Tarapacá donde se produce más de 90% de la quinua chilena y se encuentra mayoritariamente la población indígena Aymara. Múltiples factores pueden explicar esta falta de quinua, destacan por ejemplo: precios, cam...
