Molecular Epidemiology of Caliciviruses Causing Outbreaks and Sporadic Cases of Acute Gastroenteritis in Spain
2002
ABSTRACT The molecular epidemiology of human caliciviruses (HuCVs) causing sporadic cases and outbreaks of acute gastroenteritis around eastern Spain (Catalonia and the Valencian Community) was studied by reverse transcription-PCR (RT-PCR) and by sequencing part of the RNA polymerase gene in open reading frame 1. HuCVs were detected in 44 of 310 stool specimens (14.19%) negative for other enteric pathogens obtained from children with acute gastroenteritis. Norwalk-like viruses (NLVs) were the most common cause of the gastroenteritis outbreaks investigated here. They were detected in 14 out of 25 (56%) outbreaks with an identified pathogen. Genotypes producing both sporadic cases and outbrea…
Post-larval development of the microcotylid monogenean Sparicotyle chrysophrii (Van Beneden and Hesse, 1863): comparison with species of Microcotylid…
2011
Abstract The chronology of post-larval development in S. chrysophrii, a polyopisthocotylean monogenean parasite of the gilthead seabream (Sparus aurata L.), was experimentally studied. It is compared with other species within the Microcotylidae and the Heteraxinidae, including an analysis of the changes in attachment and the growth rate. Gilthead seabreams infected by larvae of S. chrysophrii were killed periodically in order to collect the different developmental stages. Parasite total body length, haptor length, largest clamp width, and total number of clamps were recorded. Specimens of S. chrysophrii in culture conditions at 20 °C became gravid after 26–30 days, with 37 pairs of clamps. …
Degradation of vanillic acid and production of guaiacol by microorganisms isolated from cork samples
2003
The presence of guaiacol in cork stoppers is responsible for some cases of cork taint causing unpleasant alterations to wine. We have performed a characterization of the cork-associated microbiota by isolating 55 different microorganisms: eight yeast, 14 filamentous fungi or molds, 13 actinomycetes and 20 non-filamentous bacteria. A screening for degradation of vanillic acid and guaiacol production showed that none of the filamentous fungi could achieve any of these processes. By contrast, five of the eight yeast strains isolated were able to degrade vanillic acid, although it was not converted to guaiacol. Guaiacol production was only detected in four bacterial strains: one isolate of Baci…
Is it possible to predict late antepartum stillbirth by means of cerebroplacental ratio and maternal characteristics?
2019
Objective: To examine the potential value of fetal ultrasound and maternal characteristics in the prediction of antepartum stillbirth after 32 weeks’ gestation. Methods: This was a retrospective multicenter study in Spain. In 29 pregnancies, umbilical artery pulsatility index (UA PI), middle cerebral artery pulsatility index (MCA PI), cerebroplacental ratio (CPR), estimated fetal weight (EFW), and maternal characteristics were recorded within 15 days prior to a stillbirth. The values of UA PI, MCA PI, and CPR were converted into multiples of the normal median (MoM) for gestational age and the EFW was expressed as percentile according to a Spanish reference range for gestational age. Data fr…
Analysis of the process of environmental impact assessment for seawater desalination plants in Spain
2014
Desalination generates drinking water and enhances the economic, social, and environmental development of many areas with few water resources, such as parts of the Middle East, North Africa, and southern Europe (such as Spain and Cyprus). Desalination plants may cause environmental impacts in coastal areas and so it is necessary to submit plans for new plants to a process of environmental impact assessment (EIA) in order to achieve more environmentally viable projects, meaning: optimal locations; appropriately used systems and technologies; effective preventive, compensatory, and corrective measures; and social and environmental acceptance. This article contains a study of the process of en…
Las culturas de la emigración española: reflejos audiovisuales de la clase obrera
2019
[spa] El objetivo del presente artículo es estudiar la representación de la emigración española hacia Europa, colocando el acento en su pertenencia a la clase obrera. Por ello, consideraremos films rodados en el contexto franquista, propuestas realizadas al margen de la industria o militantes, películas producidas por los países de acogida o audiovisuales dirigidos por personas que hayan vivido la experiencia de la emigración (primera y segunda generación). Todas estas distintas variables nos permitirán conocer y estudiar la complejidad que entraña abordar este tema y a su vez también analizaremos la relevancia que se concede en estos títulos a la condición obrera. Asimismo, valoraremos la …
Mineral profile of Spanish commercial baby food.
2015
Commercial baby foods are an important part of the daily intake of babies from 6 to 12 months. The mineral profile of commercial baby foods in Spain was determined to establish levels of essential and non-essential elements, and their contribution to adequate intake (AI) and estimated average requirement (EAR). Thirty-five jars of commercial foods containing meat, fish, vegetables and fruit were obtained from the Spanish market and the mineral composition determined for 14 elements. In general, the baby foods analysed were sufficient for an adequate mineral intake, but contributions to AI and EAR for iron, zinc and calcium were very low (5-20%, 10-60% and 10-70%, respectively). This deficie…
Authentication of Alicante’s Mountain cherries protected designation of origin by their mineral profile
2011
Abstract Chemometric analysis of inductively coupled plasma optical emission spectroscopy (ICP-OES) data was employed to verify the origin of cherry samples of different areas of Spain: Aragon, Caceres, Castellon, Huesca and Alicante’s Mountain Protected Geographic Indication (PGI). The ability of multivariate analysis methods, such as discriminant analysis (DA), was used to achieve cherry classification from their mineral content. The study was performed using 22 variables (concentrations of Al, As, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Se, Sr, Ti and Te) and 23 variables (concentrations of Al, As, B, Ba, Be, Bi, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mo, Na, Ni, Pb, Se, Sr…
Gracia y gobierno en la administración valenciana del seiscientos. Hacia nuevos consensos
2015
Desde 1645 dos miembros de la nobleza local entraron a formar parte de la sala criminal de la Audiencia valenciana. Como consejeros de capa y espada asumieron competencias en materias de gracia y gobierno. Con esta medida se introdujo una moderación del arbitrio virreinal en tales ejercicios. Pero, sobre todo, la corona convirtió a la pequeña y mediana nobleza del reino en nueva colaboradora de su política de control estamental. From 1645 two members of the local nobility came to form part of the Criminal Chamber of the Valencian audience. As Ministers of «capa y espada» took powers in matters of Grace and Government. This measure was introduced a moderation of the Viceregal discretion in s…
Mitochondrial DNA haplotype frequencies in natural and experimental populations of Drosophila subobscura.
1998
Abstract The evolution of Drosophila subobscura mitochondrial DNA has been studied in experimental populations, founded with flies from a natural population from Esporles (Majorca, Balearic Islands, Spain). This population, like other European ones, is characterized by the presence of two very common (>96%) mitochondrial haplotypes (called I and II) and rare and endemic haplotypes that appear at very low frequencies. There is no statistical evidence of positive Darwinian selection acting on the mitochondrial DNA variants according to Tajima's neutrality test. Two experimental populations, with one replicate each, were established with flies having a heterogeneous nuclear genetic back…
