Oral intake of cadmium, cobalt, copper, iron, lead, nickel, manganese and zinc in the university student's diet.
1993
A duplicate diet meal study was carried out with a group of university students living in a hostel, in order to estimate the intake of Zn, Cd, Co, Cu, Fe, Mn, Ni and Pb. Zn, Cu, Fe, Mn and Ni were determined by flame atomic absorption spectrophotometry and Cd, Co and Pb by graphite furnace atomic absorption spectrophotometry after a nitric acid wet digestion procedure. The estimated intake values from the contents of breakfast, lunch, dinner and drinks were compared with the values of the Provisional Tolerable Daily Intake (PTDI) in the case of Cd and Pb, Recommended Dietary Allowances (RDA) of Co, Fe and Zn and Estimated Safe and Adequate Dietetic Daily Intake (ESADDI) of Cu and Mn.

Dietary intake of ochratoxin A from conventional and organic bread
2006
Ochratoxin A (OTA) was extracted from 100 bread samples by using accelerated solvent extraction (ASE) and analyzed with liquid chromatography coupled with fluorescence detection. The presence of OTA was confirmed by methyl-ester derivatization. Bread samples were bought from different bakeries and supermarkets, 74 of non-organic and 26 of organic bread. The incidence of OTA varied between 20.3% and 23.0% for non-organic and organic bread, respectively. The highest values were obtained with non-organic versus organic products, five samples exceeded the European maximum permitted limit of OTA (3 ng/g) for this product. Estimated daily intake of OTA in this study was 1.6 ng/kg b.w./day. This v…
Recombination profiles between Tomato yellow leaf curl virus and Tomato yellow leaf curl Sardinia virus in laboratory and field conditions: evolution…
2012
Tomato yellow leaf curl Sardinia virus and Tomato yellow leaf curl virus have co-existed in Italian tomato crops since 2002 and have reached equilibrium, with plants hosting molecules of both species plus their recombinants being the most frequent case. Recombination events are studied in field samples, as well as in experimental co-infections, when recombinants were detected as early as 45 days following inoculation. In both conditions, recombination breakpoints were essentially absent in regions corresponding to ORFs V2, CP and C4, whereas density was highest in the 3′-terminal portion of ORF C3, next to the region where the two transcription units co-terminate. The vast majority of brea…
Direct and indirect exogenous contamination by pesticides of rice-farming soils in a Mediterranean wetland.
2003
It is known that the sources of soil contamination can be endogenous or exogenous and that exogenous contamination may be direct or indirect. In this work, an environmental pesticide fate study was conducted in soil profiles collected from 23 rice field sites in an important Mediterranean wetland (Albufera Natural Park, Valencia, Spain) from April 1996 to November 1997. Temporal and spatial distribution of 44 pesticide residues in an alluvial Mediterranean soil (gleyic-calcaric Fluvisol, Fluvaquent) were monitored. During this period, the levels of pesticide residues in different soil horizons (Ap1 0–12 cm, Ap2 12–30 cm, ApCg 30–50 cm, C1gr 50–76 cm, and C2r 76–100 cm) were investigated. In…
Psychosocial and environmental correlates of active commuting for university students.
2009
Abstract Objective To examine psychosocial and environmental correlates of active commuting to university (ACU) and explore its association with overall physical activity among college students. Methods The sample included 518 students (mean 22.4 years; 59.7% female) from two universities in Valencia, Spain. Weekly estimations of energy expenditure from ACU and total physical activity were obtained. Socio-economic status, self-efficacy, barriers to active transport, access to car and motorbike, access to public transport, walking and cycling facilities and distance to university were assessed. Data were collected April and May of 2009, using a self-administered survey. A structural equation…
Changes in physical activity domains during the transition out of high school: Psychosocial and environmental correlates
2015
Background:This study examined changes in multiple physical activity domains during the transition out of high school and psychosocial and environmental determinants of these changes.Methods:A 1-year prospective study was designed. The baseline sample was composed of 244 last-year high school students (58.6% female) from Valencia, Spain. Follow-up rate was 46%. Physical activity and potential determinants were measured by the Global Physical Activity Questionnaire and other evaluated scales in 2 waves.Results:Total physical activity and active commuting (AC) decreased, respectively, by 21% and 36%, only in males. At time 1, access to car/motorbike (inverse), planning/psychosocial barriers (…
Claves para entender los efectos de la crisis económica actual en el modelo turístico valenciano
2016
El turismo en la Comunidad Valenciana es una actividad económica de carácter estructural. Una de las características más evidentes del desarrollo turístico valenciano es su polarización espacial, con una elevada concentración del crecimiento en el litoral, a ello se une su carácter estacional, lo que junto con la primacía de la oferta extrahotelera, constituye la característica diferenciadora del turismo valenciano. Desde 2009, el análisis de la información estadística oficial nos muestra unas ligeras modificaciones en la demanda con claro impacto sobre la oferta (reducción del gasto por turista, aumento de las estancias de fines de semana, reducción de la estancia media, aumento del turism…
Translation as a measure of literary domination: the case of Quebec literature translated in Spain (1975-2004)
2010
Recent literary manifestos claim that “the center is no longer the center” (Le Devoir 2007). Indeed, it is generally admitted that Quebec literature has been more or less independent from the French field since the 1970’s. However, the analysis of the translation of this literature –its international circulation, and the almost compulsory stopover in France before being selected for translation by the agents of other literary fields– reveals various mechanisms through which the French symbolic center still exerts its power. Drawing on the application of Pierre Bourdieu’s sociology of culture to the international space (Casanova 1999; Sapiro 2007, 2008; etc.), this article argues that transl…
Sobre la recepción de Aretino en España a través de sus traducciones
2021
En primer lugar se pasa revista a los escasos estudios que se han ocupado de la recepción de Aretino en la literatura española. Tras ello, se analizan otras posibles vías de penetración de la obra de Aretino en España, como por ejemplo el contenido de los prólogos de algu- nas de las traducciones al castellano y al catalán hechas entre 1547 y 2000, o bien la selec- ción de textos traducidos. En tercer y último lugar, se estudia la calidad de todas las versiones localizadas. El trabajo se completa con un detallado catálogo de todas las traducciones de obras de Aretino publicadas hasta ahora en España, tanto en castellano como en catalán.Firstly there is a review of the rather few studies whi…
Effect of two antihypertensive combinations on metabolic control in type-2 diabetic hypertensive patients with albuminuria: a randomised, double-blin…
2001
The objective of this study was to compare, at equal blood pressure (BP) reduction, the effect of two different combinations on metabolic control and albuminuria in type 2 diabetic hypertensive patients with albuminuria. This was a prospective, randomised, double-blind, parallel, controlled trial carried out in 11 Spanish hospitals. A total of 103 type 2 diabetic patients with stable albuminuria and BP not controlled on monotherapy were randomised of which 93 finished the study. After a 4-week single-blind placebo period, patients were randomised to verapamil SR/trandolapril 180/2 mg (VT) or to enalapril/hydroclorothiazide 20/12.5 mg (EH). Treatment duration was 6 months. The main outcome m…
