La fondazione del monastero di Santa Chiara di Piazza Armerina (1320-1340): un vuoto documentario
2017
ITALIANO: Il numero degli insediamenti francescani femminili in Sicilia nel XIII e XIV secolo è ridotto e la ricostruzione della storia dei pochi monasteri esistenti è resa più complessa dalla mancanza di documenti che accomuna buona parte di essi. È il caso del monastero di Santa Chiara di Piazza Armerina la cui storia trecentesca, a partire dalla fondazione, sembra essere avvolta nell’oblio. Il saggio si propone, sulla scorta dei pochi documenti rinvenuti, di chiarire alcuni elementi legati alla sua fondazione ad opera di Guglielmo Caldarera barone di Bifara e di Favarotta. / ENGLISH: The number of female franciscan settlements in Sicily in the 13th and 14th centuries is limited and the r…
Lentes de contacto rígidas permeables al gas corneo-esclerales de alto Dk en la rehabilitación visual de pacientes con queratocono
2017
INTRODUCCIÓN Las ectasias corneales son distrofias progresivas que afectan a la morfología corneal, provocando alteraciones funcionales debido a que inducen una forma cónica irregular, disminuyendo la visión de los pacientes. El queratocono es una ectasia corneal que provoca aberraciones de alto orden que empeoran la calidad de visión, especialmente en los casos donde la enfermedad está más desarrollada. De entre todos los tratamientos actuales, la cirugía con implante de anillos intracorneales intenta eliminar la deformidad de la córnea para mejorar la agudeza visual. Los resultados visuales tras la cirugía en unos casos son satisfactorios, en cambio, en otros, los pacientes no quedan sati…
Peñón de la Zorra y Puntal de los Carniceros (Villena, Alicante): Revisión de dos conjuntos de yacimientos campaniformes en el corredor del Vinalopó
2002
En el presente artículo se revisa la información existente sobre dos yacimientos campaniformes del Alto Vinalopó –Peñón de la Zorra y Puntal de los Carniceros–. Su importancia dentro de la investigación en tierras levantinas los ha convertido en una referencia casi obligatoria desde su publicación por parte de J. M. Soler García. In this article is cheked information about two bell beaker sites from Vinalopo Valley –Peñón de la Zorra and Puntal de los Carniceros–. The importance of this archaeological sites of investigation concerning Levante areas have got that these places would be an obligatory reference since the publication by J.M. Soler Garcia.
El marco cronológico a partir de la evidencia Radiocarbónica del yacimiento de La Vital
2011
La excavación del yacimiento de La Vital proporciona una oportunidad única para revisitar tanto el marco cronológico del llamado Horizonte Campaniforme de Transición (Bernabeu, 1984), como el inicio de la metalurgia en las comarcas centrales del País Valenciano, en concreto, y en el Sureste peninsular, en general. Antes que nada, sorprende que toda la atención prestada a la cronología radiocarbónica ligada a la introducción de la economía agropecuaria en el Mediterráneo Occidental (Zilhão, 1999; Bernabeu et al., 2003) se vaya diluyendo, sin aparente motivo, a lo largo del desarrollo del Neolítico. Así, las pertinentes discusiones sobre el efecto de la “madera vieja” (Schiffer, 1986) y la, c…
Il campanile della cattedrale di Piazza Armerina, dal tardogotico al rinascimento

Insights into the relationships of Palearctic and Nearctic lymnaeids (Mollusca : Gastropoda) by rDNA ITS-2 sequencing and phylogeny of stagnicoline i…

Fascioliasis by Fasciola hepatica is the vector-borne disease presenting the widest latitudinal, longitudinal and altitudinal distribution known. F. hepatica shows a great adaptation power to new environmental conditions which is the consequence of its own capacities together with the adaptation and colonization abilities of its specific vector hosts, freshwater snails of the family Lymnaeidae. Several lymnaeid species only considered as secondary contributors to the liver fluke transmission have, however, played a very important role in the geographic expansion of this disease. Many of them belong to the so-called "stagnicoline" type group. Stagnicolines have, therefore, a very important a…
Determination of essential biomarkers in lung cancer: a real-world data study in Spain with demographic, clinical, epidemiological and pathological c…
2022
Abstract Background The survival of patients with lung cancer has substantially increased in the last decade by about 15%. This increase is, basically, due to targeted therapies available for advanced stages and the emergence of immunotherapy itself. This work aims to study the situation of biomarker testing in Spain. Patients and methods The Thoracic Tumours Registry (TTR) is an observational, prospective, registry-based study that included patients diagnosed with lung cancer and other thoracic tumours, from September 2016 to 2020. This TTR study was sponsored by the Spanish Lung Cancer Group (GECP) Foundation, an independent, scientific, multidisciplinary oncology society that coordinates…
Maintenance of the intestinal tube in Caenorhabditis elegans: the role of the intermediate filament protein IFC-2.
2008
The Caenorhabditis elegans intestinal lumen is surrounded by a dense cytoplasmic network that is laterally attached to the junctional complex and is referred to as the endotube. It localizes to the terminal web region which anchors the microvillar actin filament bundles and is particularly rich in intermediate filaments. To examine their role in intestinal morphogenesis and function, C. elegans reporter strains were generated expressing intestine-specific CFP-tagged intermediate filament polypeptide IFB-2. When these animals were treated with dsRNA against intestinal intermediate filament polypeptide IFC-2, the endotube developed multiple bubble-shaped invaginations that protruded into the …
The human gene encoding cytokeratin 20 and its expression during fetal development and in gastrointestinal carcinomas
1993
The differentiation of the predominant cell types of the mucosal epithelium of the mammalian gastrointestinal tract is characterized by increasing amounts of an intermediate-sized filament (IF) protein designated cytokeratin (CK) 20 which is a major cellular protein of mature enterocytes and goblet cells. Here we report the isolation of the human gene encoding CK 20, its complete nucleotide sequence and the amino acid sequence deduced therefrom that identifies this polypeptide (mol. wt. 48553) as a member of the type I-CK subfamily. Remarkable, however, is the comparably great sequence divergence of CK 20 from all other known type I-CKs, with only 58% identical amino acids in the conserved …
Species-Specific Aggregation Factor in Sponges
1978
An aggregation factor (AF) from the siliceous sponge Suberites domuncula has been isolated and purified by the following steps: Sepharose 2 B gel chromatography, sucrose gradient, Nonidet treatment, Sephadex G-100 gel chromatography and DEAE-Sephadex ion-exchange chromatography. By this procedure the AF was purified 1340-fold with a 63% yield nearly to homogeneity. The AF is originally associated with large particles, characterized by a sedimentation of 2200 S. These particles have been visualized electron microscopically; they are characterized by a filament-like shape of a length of 3400 A and a cross-sectional diameter of 230 A. The purified, low-molecular weight AF has a buoyant density…
