Early-life exposome and lung function in children in Europe: an analysis of data from the longitudinal, population-based HELIX cohort
(Elsevier, 2019-02-06)Background: Several single-exposure studies have documented possible effects of environmental factors on lung function, but none has relied on an exposome approach. We aimed to evaluate the association between a broad range ... -
Eating quality and health-promoting properties of two sweet cherry (Prunus avium L.) cultivars stored in passive modified atmosphere
(SAGE Publications, 2015)Two sweet cherry cultivars ('New Star' and 'Sweet Heart') were chosen to explore the impact of passive modified atmosphere packaging on the eating quality and health-promoting properties of fruit. Packaged and unpackaged ... -
Eating quality of 'Fuji' apples affected by a period of cold air after ULO storage.
(John Wiley & Sons, 2012-02-01)Over two subsequent seasons, emission of volatile compounds, consumer acceptability and quality parameters were analyzed in “Fuji” apples. In both seasons, apples were harvested at the same maturity stage and stored for ... -

Editorial: Physiological, Molecular and Genetic Perspectives of Chilling Tolerance in Horticultural Crops
(Frontiers Media, 2020-12-10)Horticultural crops have high economic, and enrich our lives through their aesthetic and nutritional value. Many horticultural species originate from tropical regions and are sensitive to cold at every stage of their ... -
Editorial: physiological, molecular and genetic perspectives of chilling tolerance in horticultural crops, volume II
(2022-10-13)For crops of tropical and subtropical origin, exposure to low temperatures often causes chilling injury symptoms, which can range from altered appearance (such as surface pitting and discoloration) to severe physiological ... -
Efecto de la amputación de antenas en machos y hembras, de la presencia de planta y de la concentración de feromona en el apareamiento de Sesamia nonagrioides Lef.
(Espanya. Ministerio de Medio Ambiente y Medio Rural y Marino, 1998)Se ha estudiado en laboratorio algunos de los factores que pueden influir en el apareamiento de los individuos de Sesamia nonagrioides Let'., como son la presencia de antenas en los individuos de ambos sexos, la presencia ... -
Effect of controlled atmospheres and shelf life period on concentrations of volatile substances released by 'Pink Lady' apples and on consumer acceptance
(Society of Chemical Industry; John Wiley & Sons, 2009)ACKGROUND: ‘Pink Lady®’ (Malus × domestica Borkh.) apples were harvested at commercial maturity and stored at 1 °C under either air or controlled atmosphere (CA) conditions (2.5 kPa O2: 3 kPa CO2 and 1 kPa O2: 2 kPa CO2) ... -
Effect of enzymatic treatments on dietary fruit fibre properties
(Taylor & Francis, 2017-04-23)Here we studied the modification of fibres derived from the fruit juice industry to prepare new value-added ingredients. These by-products are usually composted or used as animal feed. In this regard, fibres from apple, ... -
Effect of four novel bio-based DES (Deep Eutectic Solvents) on hardwood fractionation
(MDPI, 2020)Using the basic principle of construction between a hydrogen bond acceptor (HBA) and a hydrogen bond donor (HBD), four bio-based deep eutectic solvents (DESs) were prepared in a 1:2 molar ratio of HBA:HBD. 2,3-Dihydroxyp ... -
Effect of fungal mycelia on the HPLC–UV and UV–vis spectrophotometric assessment of mycelium-bound epoxide hydrolase using glycidyl phenyl ether
(Elsevier, 2016)The use of mycelia as biocatalysts has technical and economic advantages. However, there are several difficulties in obtaining accurate results in mycelium-catalysed reactions. Firstly, sample extraction, indispensable ... -
Effect of novel deep eutectic solvents on the endo/exo ratio of diels–alder reactions at room temperature
(American Chemical Society, 2021)The Diels–Alder reaction is a prototypical example of a thermally allowed [4 + 2] cycloaddition with good control over the regio- and stereochemical outcomes. Therefore, Diels–Alder reactions in which adjacent stereocenters ... -
Effect of polymer coating composition on the aggregation rates of Ag nanoparticles in NaCl solutions and seawaters
(Elsevier, 2018-08-01)The aggregation behaviour of polymer-coated silver nanoparticles (AgNPs) was characterized in NaCl solutions, and in two seawaters of different salinities and dissolved organic matter (DOM) contents. Representative organic ... -
