Mapping of Research Activity, Dominance and Collaboration Pattern in Pneumonia (2001-2015): Snapshot and Gaps
2019
Background: This article describes a bibliometric review of the scientific production, geographical distribution, collaboration, impact, and subject area focus of pneumonia research indexed on the Web of Science over a 15-year period. Methods: We searched the Web of Science database using the Medical Subject Heading (MeSH) of "Pneumonia" from January 1, 2001 to December 31, 2015. The only document types we studied were original articles and reviews, analyzing descriptive indicators by five-year periods and the scientific production by country, adjusting for population, economic, and research-related parameters. Results: A total of 22,694 references were retrieved. The number of publications…
Seasonal population dynamics of Zeuxapta seriolae (Monogenea: Heteraxinidae) parasitising Seriola dumerili (Carangidae) in the Western Mediterranean.
2013
We examined the seasonal and yearly population dynamics of the monogenean pathogen Zeuxapta seriolae on juvenile fish from wild populations of Seriola dumerili. The study is based on bimonthly monitoring between April, 2005 and April, 2007 off Majorca, and newly obtained monogenean population data for juvenile fish from three additional localities in the Western Mediterranean (off Alicante, Corsica and Sardinia). We documented the highest intensities and abundances of Z. seriolae, with mean abundance values similar to or higher than those reported in the single case of wild fish mortalities reported to date. There was a recurrent pattern of seasonal change in infection with Z. seriolae in t…
Remdesivir for the Treatment of Hospitalised Patients with COVID-19 (DisCoVeRy): A Randomised, Controlled, Open-Label Trial
2021
Background: The antiviral efficacy of remdesivir is still controversial. We aimed at evaluating its clinical effectiveness in patients with COVID-19 requiring oxygen and/or ventilator support. Methods: In this European multicentre, open-label, parallel-group, randomised, controlled trial in adults hospitalised with COVID-19 (DisCoVeRy, NCT04315948; EudraCT2020-000936-23), participants were randomly allocated to receive usual standard of care alone or in combination with intravenous remdesivir (200 mg on day 1, then 100 mg once-daily for 9 days or until discharge). Treatment assignation was performed via web-based randomisation stratified on illness severity and administrative European regio…
Los retos del sistema educativo en España
2011
International audience; A lo largo de las últimas décadas, el sistema educativo español ha cambiado profundamente. Sin embargo, a pesar de los esfuerzos realizados y de las múltiples reformas emprendidas, la eficacia interna y externa del sector sigue siendo pequeña en comparación con otros países de nuestro entorno. Gran parte de los problemas que padece el sector se debe a su escasa diversidad y a su ausencia de diferenciación. A nuestro juicio, organizar el sistema de enseñanza de manera que cada alumno encuentre un lugar en la esfera educativa que le permita adquirir unas cualificaciones a la medida de sus posibilidades y negociables en el mercado de trabajo es el mayor reto al que se e…
Ontogeny of gonadotropin releasing hormone and gonadotropin immunoreactivity in brain and pituitary of normal and estrogen-treated guppies, Poecilia …
1987
Gonadotropin releasing hormone (GnRH) and gonadotropic hormone (GTH) were identified by immunohistochemistry in the brains and pituitaries of neonate, juvenile and adult guppies. GTH was present in some cells of the pars intermedia (pi) and proximal pars distalis (ppd) of all animals. GnRH was found in the perikarya of the nucleus olfactoretinalis. In the pituitaries of juvenile 30-day-old guppies, GnRH-immunoreactive cells existed in a "juvenile pattern", whereas in adult animals GnRH was recognized in only a few cells. GnRH-immunoreactive fibers were seen in the pituitaries of animals that were 30 days or older. In adult guppies, the ventral and lateral ppd (the gonadotropic region) conta…
Ocular gelling microspheres: in vitro precorneal retention time and drug permeation through reconstituted corneal epithelium.
2008
Purpose: The model drug norfloxacin (NOR)was encapsulated into trehalose (TRH) and hydroxyethylcellulose(NAT) microspheres to obtain a novel gelling ophthalmic delivery system for prolonged release on corneal tissue. Methods: We assessed NOR release from microspheres, prepared by the emulsion-solvent evaporation method. A new in vitro tear turnover model, including inserts containing reconstituted human corneal epithelium (RHC), was designed to evaluate the TRH/NAT microspheres’ precorneal retention time. Bioadhesive properties of TRH/NAT microspheres were validated by using drug-loaded microspheres prepared with gelatine (GLT) commonly used as reference material in adhesion studies. Result…
Assessment of the Sabellaria alveolata reefs’ structural features along the Southern coast of Sicily (Strait of Sicily, Mediterranean Sea)
2022
The honeycomb worm Sabellaria alveolata is a gregarious tube-dwelling polychaete that builds remarkable biogenic reefs in marine coastal waters. Sabellaria alveolata reefs are considered valuable marine habitats requiring protection measures for their conservation, as they play a key role in the functioning of coastal ecosystems. Sabellarid reefs are extensively developed along the Atlantic coasts of Europe and reported for the Mediterranean Sea and the Italian coasts, where large reefs have been recorded in several localities. Fragmentary information is available on their health status, Sabellaria reefs thus being listed as “Data Deficient” in the Red List of Marine Habitats. To fill this …

Conectando con el pasado. Redes sociales en la Prehistoria Reciente
2022
Las redes sociales virtuales han cambiado el modo de vida de la humanidad. Permiten interactuar con personas de todo el planeta o difundir noticias. Sin embargo, las redes sociales no son un invento contemporáneo. Desde los orígenes de la humanidad, las redes sociales constituyen el complejo entramado sobre el que se tejen las estructuras colectivas que conforman las sociedades humanas. Esta densa trama de relaciones, que comienza a ser tejida en círculos íntimos, tiene el potencial de crecer y extenderse hasta los confines más distantes. Las estructuras de toda sociedad humana se edifican sobre esta urdimbre relacional, independientemente de su grado de complejidad. Por ello el estudio de …
Frihet, fantasi og utfoldelse: En kvalitativ studie av estetiske arbeidsformer i lærerutdanningene
2017
Artikkelen undersoker hva slags forstaelse laererutdannere og laererstudenter har av estetiske arbeidsformer i undervisningen i laererutdanningene. Studien er en kvalitativ intervjuundersokelse blant laererutdannere og laererstudenter ved en norsk laererutdanningsinstitusjon. I lys av danningsteoretisk og didaktisk teori, finner studien at laererutdannere og laererstudenters forstaelse av estetiske arbeidsformer i undervisningen er kjennetegnet av «frihet» som fravaer av tvang og fasit i arbeid med laerestoffet, «fantasi» som bruk av forestillingsevnen slik at kunnskapen blir personlig, og «utfoldelse» som sosialisering inn i et fellesskap gjennom tilbakemeldinger pa egen atferd. Til sammen…
