Inferring Phytoplankton, Terrestrial Plant and Bacteria Bulk δ¹³C Values from Compound Specific Analyses of Lipids and Fatty Acids.
2015
Stable isotope mixing models in aquatic ecology require δ13C values for food web end members such as phytoplankton and bacteria, however it is rarely possible to measure these directly. Hence there is a critical need for improved methods for estimating the δ13C ratios of phytoplankton, bacteria and terrestrial detritus from within mixed seston. We determined the δ13C values of lipids, phospholipids and biomarker fatty acids and used these to calculate isotopic differences compared to the whole-cell δ13C values for eight phytoplankton classes, five bacterial taxa, and three types of terrestrial organic matter (two trees and one grass). The lipid content was higher amongst the phytoplankton (…
Environmental remediation using nanomaterial as adsorbents for emerging micropollutants
2023
Water shortage and scarcity are issues of global concern. Water pollution caused by organic micropollutants further aggravates the problem, by rendering an already scarce resource unfit for human consumption. The existing conventional wastewater treatment methods and infrastructure were not designed to eliminate micropollutants. Therefore, their inefficiencies call for modern methods for removing emerging micropollutant residues such as Active Pharmaceutical Ingredients (APIs), Endocrine Disrupting Compounds (EDCs), personal care products and pesticides. The use of nanomaterials, for the abatement of micropollutants in water is gaining traction in recent years, due to the abundance of susta…

Valor pronóstico de los cambios en la rigidez arterial en la hipertensión arterial esencial
2020
INTRODUCCIÓN: La evaluación del daño orgánico subclínico, incluyendo la velocidad de la onda del pulso (VOP), podría ayudar a mejorar la estratificación del riesgo en la hipertensión arterial (HTA), especialmente en pacientes de riesgo intermedio. Sin embargo, no se dispone de información suficiente acerca de la posible relación de otros parámetros de rigidez vascular (incluyendo el echo-tracking o el índice de aumento del pulso) con el desarrollo de daño orgánico subclínico o de eventos cardiovasculares (CVs), ni tampoco para la integración de diversos parámetros. Ayudar a precisar mejor cual es la utilidad, interpretación y el mejor uso de estas herramientas de evaluación de rigidez vascu…
Velocidad de crecimiento tumoral: Definición del valor pronóstico en el carcinoma epidermoide cutáneo y en el melanoma
2015
La incidencia del cáncer de piel se ha incrementado exponencialmente en los últimos años debido en parte a la mayor longevidad de la población general a nivel mundial, y en parte atribuible a la modificación del comportamiento social con respecto a la exposición solar con un predominio de un patrón de exposición intenso vacacional desde mediados del siglo XX. Dentro de los diferentes cánceres de piel clasificados en base a la tasa de frecuencia/mortalidad global, el melanoma maligno (MM) y el carcinoma epidermoide cutáneo (CEC) son los más relevantes en el campo de la Dermatología. En los últimos años se han producido grandes avances en la capacidad de predecir el pronóstico y en el tratami…
Incidentality on a continuum: A comparative conceptualization of incidental news consumption
2020
This article seeks to contribute to theorizing the dynamics of incidental news consumption. Through an analysis of 200 semi-structured interviews with people in Argentina, Finland, Israel, Japan, and the United States, we show that intentionality in news consumption can be viewed on a continuum, which goes from deliberately setting apart time to access the news on specific outlets to skimming through unsought-for news on social and broadcast media, with intermediate practices such as respondents setting up an environment where they are more or less likely to encounter news. Drawing on structuration theory, this article conceptualizes incidental news in the context of the wider media environ…
Kinetic evidence for the incorporation of the [(pentamethylcyclopentadienyl) (2,2′-bipyridyl)(aquo)rhodium(III)] complex into DPPC vesicles
2008
Abstract The binding of the [(pentamethylcyclopentadienyl) (2,2′-bipyridyl)(aquo)rhodium(III)] complex [Cp*RhIII(bpy)H2O]2+, to l -α-dipalmitoylphosphatidyl choline (DPPC) vesicles has been estimated by studying the kinetics of the electron transfer reaction between the rhodium(III) complex and formiate ions. Kinetic measurements carried out under anaerobic conditions in absence and presence of DPPC show that the total reaction is composed of two steps. The rate of the first reaction increases with the phospholipid concentration, while that of the second process is independent of the concentration of DPPC. This is consistent with a reaction, where the two reacting species are partitioned be…
Advances in Wine Fermentation
2021
Fermentation is a well-known natural process that has been used by humanity for thousands of years, with the fundamental purpose of making alcoholic beverages such as wine, and also other non-alcoholic products. From a strictly biochemical point of view, fermentation is a process of central metabolism in which an organism converts a carbohydrate, such as starch or sugar, into an alcohol or an acid. The fermentation process turns grape juice (must) into wine. This is a complex chemical reaction whereby the yeast interacts with the sugars (glucose and fructose) in the must to create ethanol and carbon dioxide. Fermentation processes to produce wines are traditionally carried out with Saccharo…

2017
«Hayao Miyazaki, la lámpara maravillosa. Un estudio de su cine y de sus referencias humanistas a la luz de las conexiones culturales entre Japón y Occidente». Bajo este título, ofrecemos una completa y profunda investigación centrada en la obra integral del realizador nipón Hayao Miyazaki (1941), aunque con especial incidencia en sus once largometrajes, su única serie televisiva como director absoluto y algunos cortometrajes y mangas. Dicha investigación, en la que desgranamos los temas rectores de su trabajo –lo fantástico, lo maravilloso y lo alegórico; el viaje iniciático y los límites de la magia; la «transtextualidad» y la interculturalidad; las creaciones y recreaciones espacio-tempor…
