Estudio del tratamiento del efluente de un reactor anaerobio de membranas sumergidas (SAnMBR) mediante un sistema de fangos activados
2016
El crecimiento acelerado de los núcleos urbanos ha provocado que las aguas residuales urbanas sean una fuente importante de contaminación ambiental, siendo necesario desarrollar e implementar tecnologías enfocadas a prevenir y mitigar los graves problemas de contaminación. El uso de un reactor anaerobio de membrana sumergida (SAnMBR) para el tratamiento de aguas residuales urbanas es una alternativa que permite transformar la materia orgánica en biogás y minimizar los fangos producidos. Sin embargo produce un efluente con concentraciones de nitrógeno y fósforo similares a las del agua residual afluente, con concentraciones moderadas de materia orgánica biodegradable y metano disuelto y en o…
Variaciones espacio-temporales en la composición y/o abundancia de Hongos Micorrízicos Arbusculares (HMA) en táxones vegetales de interés para la rec…
2019
Successful arbuscular mycorrhizal fungi (AMF) symbiosis in sand dunes is a key factor for the maintenance of stable vegetation. Therefore, the main goal of this work was to study the AMF species associated with sand dunes in the Gulf of Valencia (Spain), as well as the effects of environmental and temporal factors on these AMF communities. In order to achieve these, soil samples from the rhizosphere of four plant species were seasonally collected at 6 sites during 2 years in three habitats. Frequency and relative abundance of AMF among these samples were examined. Among the ten AMF species identified, only Corymbiglomus corymbiforme and Diversispora aurantia (Diversisporaceae) had been prev…

Potencialidades del consorcio microbiano Curvularia kusanoi -Trichoderma pleuroticola como pretratamiento biológico para la degradación de fuentes fi…

Objective. To evaluate the potentiality of the microbial consortium Curvularia kusanoi L7- Trichoderma pleuroticola as biological pretreatment of high fiber sources destined for animal production. Materials and methods. The Strains used where Curvularia kusanoi L7 and Trichoderma pleuroticola. The degradative potential was evaluated through the production kinetics of cellulolytic (endo-1,4-β-glucanase and exo-1,4-β-glucanase) and ligninolytics enzymes (laccase and peroxidase) in solid submerged fermentation of bran wheat and sugarcane bagasse. The growth of the co culture in plates was analyzed. The effect of the consortium on the carbon mineralization of raw wheat straw was determined and …
Los efectos de la adopción de las NIIF en los estados financieros: Evidencia para distintos contextos, Europa y Latinoamérica
2018
Sin duda, la adopción en distintas jurisdicciones de las Normas Internacionales de Información Financiera (NIIF), elaboradas por el International Accounting Standards Board (IASB), constituye una innovación histórica sin precedentes en la regulación contable (Ball, 2016) que ha generado contextos únicos para estudiar los efectos de la adopción del modelo IASB, y cómo éstos difieren según las características de cada país (De George, Li y Shivakumar, 2016). A pesar de que son numerosos los estudios realizados, los resultados de la literatura sobre los efectos de la adopción de esta normativa no son concluyentes, y todavía quedan muchas preguntas sin respuesta (ver Brüggemann, H…
Mycotoxins in dried fruits. Decontamination procedures = Micotoxinas en frutas desecadas. Medidas de descontaminación
2014
A sensitive and reliable multi-mycotoxin method was developed for the simultaneous determination of 16 mycotoxins in dried fruits using liquid chromatography (LC) combined with electrospray ionization-triple quadrupole tandem-mass spectrometry. Mycotoxins have been extracted from the samples using a modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) procedure. In an effort to enforce the knowledge on mycotoxin occurrence and co-occurrence in dates and dried fruits, 228 samples purchased from Tunisian and Spanish markets were subjected to multi-mycotoxin liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis of 16 mycotoxins. At least one mycotoxin was detect…
Dysfunctional High-Density Lipoproteins Are Associated With a Greater Incidence of Acute Coronary Syndrome in a Population at High Cardiovascular Risk
2020
Background: Studies have failed to establish a clear link between high-density lipoprotein (HDL) cholesterol and cardiovascular disease, leading to the hypothesis that the atheroprotective role of HDL lies in its biological activity rather than in its cholesterol content. However, to date, the association between HDL functional characteristics and acute coronary syndrome has not been investigated comprehensively. Methods: We conducted a case-control study nested within the PREDIMED (Prevención con Dieta Mediterránea) cohort, originally a randomized trial in which participants followed a Mediterranean or low-fat diet. Incident acute coronary syndrome cases (N=167) were individually matched …
Reducción de la contaminación por hongos toxigénicos y micotoxinas en alimentos mediante el uso de isotiocianatos
2019
El crecimiento de hongos es una de las causas más habituales del deterioro de los alimentos. Productos como los cereales, el pan y sus derivados son especialmente susceptibles ser contaminados con hongos toxigénicos y/o micotoxinas, lo que supone un problema de seguridad alimentaria. Por ello en la presente Tesis Doctoral se han estudiado la presencia de micotoxinas en 60 muestras de masas de pizza refrigeradas y el riesgo de exposición de la población a estos compuestos. Se detectaron aflatoxinas (AFs), zearalenona (ZEA), eniatinas (ENs) y beauvericina (BEA) en el 50, 100, 100 y 3 % respectivamente. Aunque el riesgo de exposición fue moderado, el 12 % de las muestras superaba los límites m…
NBI and Laryngeal Papillomatosis: A Diagnostic Challenge: A Systematic Review.
2022
Narrow-band imaging (NBI) represents a valid aid in laryngeal squamous cell carcinoma (LSCC) diagnosis for detecting vascular changes. However, LSCC and laryngeal papillomatosis (LP) show similar vascular patterns that may lead to misdiagnosis and improper treatment. This review aims to deepen this NBI limit in order to stress a careful preoperative evaluation of laryngeal lesions. The research was carried out on PubMed, Web of Science and Scopus databases using specific keywords. The topic of research was assessed by these parameters: accuracy, sensitivity, specificity, and positive and negative predictive values. This review included only five articles: they demonstrated that NBI is bette…
Data from: Evidence for an association between post-fledging dispersal and microsatellite multilocus heterozygosity in a large population of greater …
2014
Dispersal can be divided into three stages: departure, transience and settlement. Despite the fact that theoretical studies have emphasized the importance of heterozygosity on dispersal strategies, empirical evidence of its effect on different stages of dispersal is lacking. Here, using multi-event capture-mark-recapture models, we show a negative association between microsatellite multilocus heterozygosity (MLH; 10 loci; n = 1023) and post-fledging dispersal propensity for greater flamingos, Phoenicopterus roseus, born in southern France. We propose that the negative effects of inbreeding depression affects competitive ability and therefore more homozygous individuals are more likely to di…
