Unitat didàctica : Unió Europea : fortificació o cooperació?
2012
Les reflexions sobre l'educació i les consideracions didàctiques presentades en aquest TFM, són resultat d'un any de treball al Màster de Professorat en l'UV. Reflexions necessàries abans d'entrar a un aula ja què plantjar-se quin és el paper del professor en l'educació no sempre ha estat tasca obligatòria, almenys a nivell formal. Cal saber allò que volem, quins són els objectius de l'educació per a utilitzar el mètode que facilite aconseguir-los. I aquest no és altre que el mètode constructivista i què podrà aplicar-se de manera general si aconseguim introduir la innovació educativa a les escoles. Aquest treball de reflexió s'ha intentat aplicar en aquesta unitat didàctica sobre la “Unió …
Diversity and Evolution of papillomaviruses
2017
1.1. Introducción Con el fin de averiguar las causas de las devastadoras epidemias de finales del siglo XIX, se llevaron a cabo diferentes estudios que dieron como resultado la identificación de unos nuevos agentes infecciosos, para los que se acuñó el nombre de “virus”. Desde entonces el descubrimiento de nuevos virus ha sido incesante, lo que llevó, en los años 70, a la creación de un organismo encargado de desarrollar, refinar y mantener la clasificación taxonómica de los virus, el Comité Internacional de Taxonomía Viral (ICTV), en el seno de la Unión Internacional de Sociedades Microbiológicas (IUMS). En 2014 este organismo había reconocido 3.186 especies virales pertenecientes a 104 fa…

Late-Onset Globoid Cell Leukodystrophy: Unusual Ultrastructural Pathology and Subtotal β-Galactocerebrosidase Deficiency
1990
An 11-year-old girl was found to have severely reduced β-galactocerebrosidase activity as evidence of late-onset globoid cell leukodystrophy, while her mother had almost normal enzyme activity in circulating white blood cells. Clinically, the patient showed a remitting course marked by seizures, ataxia, white-matter disease on computed tomographic scan, and reduced conduction velocities of peripheral nerves. Symptoms improved somewhat around the age of 10 years. Two sural nerve biopsies, performed 6 years apart, disclosed a demyelinating neuropathy. By electron microscopy, membrane-bound vacuolar lysosomes in Schwann cells of myelinated axons, unlike the typical needlelike inclusions seen …
Novel alpha-galactosidase A mutation in a female with recurrent strokes.
2012
Abstract Anderson–Fabry disease (AFD) is an X-linked inborn error of glycosphingolipid catabolism resulting from the deficient activity of the lysosomal exoglycohydrolase, a-galactosidase A. The complete genomic and cDNA sequences of the human alpha-galactosidase A gene have been determined and to date, several disease-causing alpha-galactosidase A mutations have been identified, including missense mutations, small deletions/insertions, splice mutations, and large gene rearrangements We report a case of a 56-year-old woman with recurrent cryptogenic strokes. Ophthalmological examination revealed whorled opacities of the cornea (cornea verticillata) and dilated tortuous conjunctival vessels.…
Clinical heterogeneity in infantile galactosialidosis
1987
A new case of infantile galactosialidosis is presented. The condition was diagnosed when the patient was 4 months of age and she died at 20 months. She exhibited some of the symptoms of classical infantile galactosialidosis but no corneal clouding, cherry-red macular spot or limitation of joint mobility. Sonographic examination showed large kidneys and thickened cardiac septa, two symptoms as yet undescribed in this disorder. Urinary oligosaccharide analysis gave grossly pathological results and subsequent fibroblast enzyme analysis showed a deficiency of alpha-neuraminidase and beta-galactosidase. The patient's clinical features are compared with the few cases so far described in the liter…
Religiosidad y comportamientos económicos ante la muerte de los comerciantes de telas al por menor en la Valencia del XVIII
2008
Este artículo analiza las actitudes ante la muerte de los comerciantes de telas al por menor en la Valencia del siglo XVIII, a través de las disposiciones testamentarias de tres miembros representativos de este grupo social; Bernardo Sumbiela, de origen francés, Juan Solernou, catalán y José Ellul, de procedencia maltesa. El hecho de que todos ellos sean de origen foráneo se corresponde con la composición social de este sector y el predominio de agentes comerciales extranjeros especialmente franceses y malteses durante toda la centuria. Observamos, especialmente, las actitudes religiosas (entierro, legado pro anima, mandas pías...), pero también sus comportamientos económicos y las estrateg…

The role ofSphagnummosses in the methane cycling of a boreal mire
2010
Peatlands are a major natural source of atmospheric methane (CH4). Emissions from Sphagnum-dominated mires are lower than those measured from other mire types. This observation may partly be due to methanotrophic (i.e., methane-consuming) bacteria associated with Sphagnum. Twenty-three of the 41 Sphagnum species in Finland can be found in the peatland at Lakkasuo. To better understand the Sphagnum-methanotroph system, we tested the following hypotheses: (1) all these Sphagnum species support methanotrophic bacteria; (2) water level is the key environmental determinant for differences in methanotrophy across habitats; (3) under dry conditions, Sphagnum species will not host methanotrophic ba…
Methanotrophy induces nitrogen fixation during peatland development
2013
Significance In peatlands, the external sources of nitrogen are mainly atmospheric, but the atmospheric nitrogen deposition alone cannot explain the long-term annual nitrogen accumulation rates to these ecosystems. Because of methodological problems, methane-induced fixation of atmospheric dinitrogen gas has been previously overlooked as an additional nitrogen input mechanism. We found that the activity of methane-oxidizing bacteria provides not only carbon but also nitrogen to peat mosses and, thus, contributes to carbon and nitrogen accumulation in peatlands, which store approximately one-third of the global soil carbon pool. Our results imply that nitrogen fixation in wetlands may be str…
