Evaluation of the genotoxic and cytochrome P450 monooxygenase‐inhibitory potential of dicuran on procaryotic and eucaryotic test systems
2000
The effect of the herbicide Dicuran 500 FL (formulated product) on the phenotypical and genotypical changes in procaryotic and eucaryotic organisms was investigated using short-term tests for detecting genotoxins. Since pesticides discharged in the water environment can modulate the mixed-function monooxygenases (MFO) detoxification system of water organisms, the in vivo and in vitro effects of Dicuran on hepatic cytochrome P450 (cyt P450) monooxygenase activities were also examined in juvenile carp (Cyprinus carpio L.). By measuring the activities of MFO in experimental carp exposed to Dicuran an attempt was made to establish whether Dicuran could be bioactivated by MFO into ultimate mutag…
In vivo Antimicrobial Activity Assessment of a Cauliflower By-Product Extract Against Salmonella Typhimurium
2020
The main objective of this work was to study the antimicrobial effect of a cauliflower by-product infusion into an affordable in vivo model (Caenorhabditis elegans). The infusion demonstrated some protective effect on non-infected and infected worms with Salmonella Typhimurium as indicated by higher survival percentile values (75, 50, 25, and 5% percentiles) as compared with those from worms unexposed to the infusion. The antimicrobial effect of the infusion was evaluated on Salmonella intestinal colonization of infected worms (24, 48, and 96 h post-infection). At 96 h post-infection, the concentration of Salmonella was reduced around 2 log cycles in infected cauliflower treated group (p < …
Prioridades de investigación en salud laboral en España
2008
La investigacion en salud laboral es un elemento crucial para impulsar de manera efectiva las politicas publicas y privadas en seguridad y salud en el trabajo1. En Espana, en los ultimos anos, y a pesar de su insufi ciencia, se han abierto diversas posibilidades de fi nanciacion de la investigacion en salud laboral con el subprograma de seguridad y salud en el trabajo del Plan Nacional I+D+i 2004-2007, el Fondo de Investigaciones Sanitarias, el Fondo de Investigacion de Proteccion Social y el Instituto Nacional de Seguridad e Higiene en el Trabajo, entre otras. Por su especial relevancia hay que mencionar la incorporacion en el Plan Nacional I+D+I 2004-2007 de un Subprograma I+D en Segurida…

De Novo Assembly and Functional Annotation of the Olive (Olea europaea) Transcriptome
2013
Olive breeding programmes are focused on selecting for traits as short juvenile period, plant architecture suited for mechanical harvest, or oil characteristics, including fatty acid composition, phenolic, and volatile compounds to suit new markets. Understanding the molecular basis of these characteristics and improving the efficiency of such breeding programmes require the development of genomic information and tools. However, despite its economic relevance, genomic information on olive or closely related species is still scarce. We have applied Sanger and 454 pyrosequencing technologies to generate close to 2 million reads from 12 cDNA libraries obtained from the Picual, Arbequina, and L…
Validation of the Marathon Motivation Scale in Chile
2021
The objective of this work was to validate the Marathon Motivation Scale (MOMS) for its application in the Chilean context. The study used a non-experimental, descriptive and transversal design. The sample was non-probability and intentional and was composed of 250 subjects (143 male and 104 female) runners who participated in the International Marathon of Viña del Mar with an average age of 29.8 (TD = 10.1) years. For the analysis of the data, an exploratory factorial analysis was carried out with free parameters, another one with seven factors fixed to the theoretical dimensions and a confirmatory factorial analysis with the items corresponding to the MOMS model. The validity and reliabil…
Strategies to exiting the COVID-19 lockdown for workplace and school: A scoping review
2021
Highlights • Epidemiological conditions should be monitored and enforced. • COVID-19 must be under control below thresholds of safeguards. • Testing, contact tracing, and isolation strategies are essential components to ease the lockdown. • The maintenance of social distancing measures is an overarching mitigation strategy. • The benefit gained from the implementation of social distancing was evident.
Vibration effect on ball score test in international vs. national level table tennis
2018
In table tennis, motor skills are crucial for discriminating player level. However, there is a dearth of studies exploring the impact of a vibrational stimulus on performance. Thirty-four male players (age 25 +/- 2 years ; body mass index, BMI 23.4 +/- 1.2 kg.m(-2)) participated in the study. Seventeen played at international level (IL), while the remaining 17 played at national level (NL). The participants underwent a ball-handling test, the ball score, before (PRE) and after (POST) a vibrational stimulus. Intra-class correlation (ICC) for the ball score result showed good reliability (ICC 0.87 for IL and 0.80 for NL). Repeated measures ANOVA showed differences between groups for ball scor…
Estudio de la Gestión de la Seguridad y Salud en el sector construcción valenciano = Study of Safety and Health Management in the construction sector…
2015
ResumenLa construcción es un sector que presenta un alto nivel de siniestrabilidad debido a sus características propias (alto componente de mano de obra y que se desarrolla al aire libre) y por sus características organizativas, como los ritmos de trabajo, las metodologías de ejecución y la elevada subcontratación. La gestión de la Seguridad y Salud es un factor determinante a la hora de obtener mejoras en la ejecución de los trabajos y menores tasas de accidentes. En este trabajo se realiza un estudio del nivel actual de gestión de la seguridad y salud en el sector construcción en Valencia (España) a partir de una encuesta realizada a técnicos con experiencia en el sector. Los principales …
The evolution of the feudal income in the marquisate of Llombai (XVI-XIX centuries)
2006
Este artículo analiza la evolución de la renta feudal de un señorío valenciano particularmente bien documentado, el marquesado de Llombai, posesión de los duques de Gandía, en un período muy extenso que va de 1486 a 1819. Se estudia la renta nominal (tanto bruta como la neta, es decir la cantidad que percibía efectivamente el señor) y la renta real o deflactada, que es la más interesante, ya que tiene en cuenta el efecto de la evolución de los precios. Esta última muestra una tendencia a la baja durante el siglo XVI, lo que indica que no pudo resistir el efecto de la llamada revolución de los precios, una recuperación en el XVII, una vez superado el fuerte bache que supuso la expulsión de l…
