Efecto del glifosato y de diferentes intermediarios metabólicos en la regulación de la ruta del siquimato
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2017) Contribución a congreso / Biltzarrerako ekarpenaEn este estudio se han abordado los mecanismos de regulación de la ruta del siquimato en la biosíntesis de los aminoácidos aromáticos. Para ello se han comparado el contenido de siquimato y de los enzimas EPSPS ... -
Effect of dietary quercetin and sphingomyelin on intestinal nutrient absorption and animal growth
Research on cancer and other conditions has shown flavonoids and sphingolipids to be food components capable of exerting chemoprotective action. Nevertheless, little is known about their effects on healthy individuals and ... -
Effect of feeding regime on composting in bins
Composting in bins is one of the most practical home composting methods. There is currently a need for greater information to improve the management of the composting process and to create home composting programs, which ... -
Effect of including whole linseed and vitamin E in the diet of young bulls slaughtered at two fat covers on the sensory quality of beef packaged in two different packaging systems
Background: Forty-six Pirenaica young bulls, slaughtered at two levels of fatness (3 and 4 mm), were used to evaluate theeffect of the inclusion of 50 g kg−1 linseed alone or with 200 IU vitamin E kg−1 in the concentrate ... -
Effect of insulin-like growth factor-I on nitrogen balance and intestinal galactose transport in rats with moderate liver cirrhosis
The malnutrition caused by liver cirrhosis (LC) often worsens the course of the disease. Patients affected by LC often have a low bioavailability of the anabolic liver peptide insulin-like growth factor (IGF)-I. The present ... -
Effects of EPSPS Copy Number Variation (CNV) and glyphosate application on the aromatic and branched chain amino acid synthesis pathways in Amaranthus palmeri
A key enzyme of the shikimate pathway, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS; EC 2.5.1.19), is the known target of the widely used herbicide glyphosate. Glyphosate resistance in Amaranthus palmeri, one of ... -
Effects of nitrogen deposition on carbon sequestration in Chinese fir forests ecosystems
Nitrogen deposition and its ecologic effects on forest ecosystems have received global attention. In this paper, the ecosystem model FORECAST was used to assess the effects of nitrogen deposition on carbon sequestration ... -
Elevated CO2 improved the growth of a double nitrate reductase defective mutant of Arabidopsis thaliana: the importance of maintaining a high energy status
Impairments in leaf nitrogen (N) assimilation in C3 plants have been identified as processes conditioning photosynthesis under elevated [CO2], especially when N is supplied as nitrate. Leaf N status is usually improved ... -
¿Están los bosques mixtos pirenaicos de pino silvestre y haya en el camino hacia la saturación por nitrógeno?
Las actividades humanas causan altos niveles de deposición atmosférica crónica de N que pueden estar trastornando el ciclo del N en los bosques de los Pirineos occidentales. Para probar esta hipótesis, se han investigado ... -
Estudio de prospectiva, análisis y propuesta de participación y colaboración de la Administración Foral de Navarra con las redes, plataformas e iniciativas de ciencia ciudadana
El objetivo de este trabajo es analizar las redes y plataformas de ciencia ciudadana existentes con el fin de realizar una propuesta para su implementación en Navarra por parte de la Administración Ambiental; para ello se ... -
Evaluación del efecto de los inhibidores de la nitrificación derivados de dimetilpirazol y la nutrición amoniacal sobre la fisiología de las plantas
Los inhibidores de la nitrificación (IN) pueden ser bien productos biológicos producidos por las plantas o de síntesis química, estos últimos son añadidos a los fertilizantes granulados, solubles o líquidos y del mismo ... -
Evaluation of the effects of forest management strategies on carbon sequestration in evergreen broad-leaved (Phoebe bournei) plantation forests using FORECAST ecosystem model
In the context of global climate change, it is critical to study how different forest management practices affect forest carbon sequestration. This is especially important for forest managers and policy makers who will ... -
Fabricación y caracterización de nanobiohíbridos: optimización de la interfaz entre nanoestructuras de oro y proteínas para posibles aplicaciones biosensoras
En las últimas décadas, la investigación en el campo de los nanomateriales se ha desarrollado considerablemente, debido a las potenciales aplicaciones de estos materiales en muy diversos campos de la ciencia. En muchas de ... -
Fat-to-glucose interconversion by hydrodynamic transfer of two glyoxylate cycle enzyme genes
The glyoxylate cycle, which is well characterized in higher plants and some microorganisms but not in vertebrates, is able to bypass the citric acid cycle to achieve fat-to-carbohydrate interconversion. In this context, ... -
Fermentation and alternative oxidase contribute to the action of amino acid biosynthesis-inhibiting herbicides
Acetolactate synthase inhibitors (ALS-inhibitors) and glyphosate (GLP) are two classes of herbicide that act by the specific inhibition of an enzyme in the biosynthetic pathway of branched-chain or aromatic amino acids, ... -
Fire in the woods or fire in the boiler: implementing rural district heating to reduce wildfire risks in the forest-urban interface
Many rural communities in British Columbia (western Canada) are at risk from wildfire. This risk will increase over time as a result of climate change because of higher average temperatures, longer growing seasons, and ... -
Forest landscape hydrology in a "new normal" era of climate and land use change
This chapter aims to clarify the effects that changing climate and quantity, quality and pattern of tree cover in forests have on the way water becomes available for human use and ecosystem integrity. To do this, the ... -
Forests may need centuries to recover their original productivity after continuous intensive management: an example from Douglas-fir stands
How long would it take for forests to recover their original productivity following continuous intensive management if they are left untouched? This issue was explored using the model FORECAST, calibrated and validated for ... -
From ground pollution to soil fertilization: an environmental assessment of soil amendments derived from organic wastes
El crecimiento de la población y sus necesidades de alimentación en las últimas décadas han sido mayoritariamente sustentados por un modelo productivo lineal a escala global basado en consumir recursos y generar residuos. ... -
Gestión forestal sostenible de masas de pino silvestre en el Pirineo Navarro
La política forestal actual se caracteriza por un compromiso hacia una gestión ecológicamente sostenible de los ecosistemas forestales. Para poder realizarla es necesario conocer los factores que afectan al uso de los ...
