Pintura califal de Bédar (Almería, 355/966)
2020
Esta investigación se centra en un texto árabe pintado sobre un elemento inusual: una balsa de agua para riego en Bédar (Almería). Junto al epígrafe que la data, hay dibujados dos animales cuadrúpedos que quizá representen una escena de caza y una cenefa decorativa; conserva asimismo otros signos gráficos y diseños muy degradados que no ha sido posible descifrar totalmente. Como hasta ahora no se había determinado su cronología, en este estudio he seguido el método habitual en Epigrafía Árabe: dibujar los trazos visibles y restituir después las partes de pintura desaparecida o muy borrada. Como resultado de este estudio queda de relieve el valor de este destacado documento de la cultura pop…
Analysis of pigments from Spanish works of art using a portable EDXRF spectrometer
2002
Nowadays there is an intensive program for the conservation, restoration and analysis of the impressive and extensive Spanish cultural heritage. In the last few years, the Unidad de Arqueometria of the ICMUV has carry out a great quantity of in situ EDXRF analysis of pigments on materials of historic and cultural interest (altarpieces, frescoes, canvas, sculptures, etc.) from museums and churches of the whole of the Spanish geography. Here we present a few examples of the analysis of works of art using x-ray fluorescence spectrometry with a portable system based on x-ray tubes and a non-cryogenic Si-PIN detector. EDXRF qualitative and non-destructive analyses of stone, pigments and preparat…
Expression in Streptomyces lividans of Nonomuraea genes cloned in an artificial chromosome
2004
A bacterial artificial chromosomal library of Nonomuraea sp. ATCC39727 was constructed using Escherichia coli-Streptomyces artificial chromosome (ESAC) and screened for the presence of dbv genes known to be involved in the biosynthesis of the glycopeptide A40926. dbv genes were cloned as two large, partially overlapping, fragments and transferred into the host Streptomyces lividans, thus generating strains S. lividansColon, two colonsNmESAC50 and S. lividansColon, two colonsNmESAC57. The heterologous expression of Nonomuraea genes in S. lividans was successfully demonstrated by using combined RT-PCR and proteomic approaches. MALDI-TOF analysis revealed that a Nonomuraea ABC transporter is e…
Correspondencia erudita entre Mayans y Muratori
1997
Ludovico Muratori, uno de los pilares de la Ilustración italiana, ejerció un notable influjo sobre la cultura española en general y, muy en particular, sobre Gregorio Mayans, cuya concepción de la religiosidad tenía grandes afinidades con la del Biliotecario de Modena. Antonio Mestre estudia y edita la correspondencia de Muratori con Mayans entre 1739 y 1743 centrada en tres aspectos: la epigrafía latina; el embargo que sufrió la edición mayansiana de la Censura de historias fabulosas de Nicolás Antonio; y, muy especialmente, consideraciones sobre el nivel cultural de los españoles y la política cultural del Gobierno. Ludovico Muratori, one of the pillars of the Italian Illustration, exerci…

I DIPINTI MURALI STACCATI: CRITICITÀ E NUOVE PROPOSTE
2015
La tesi di Laurea Magistrale a ciclo unico, in "Conservazione e Restauro dei Beni Culturali", della Dottoressa Nicoletta Chiparo, riguarda l'intervento di restauro di un lacerto di dipinto murale staccato, di età paleocristiana, raffigurante un'orante; l’approccio alle problematiche di conservazione del dipinto murale ha suggerito l’avvio di una ricerca bibliografica e di laboratorio sui materiali per la realizzazione degli strati di sacrificio per i dipinti murali staccati. Il dipinto murale, di provenienza incerta e delle dimensioni di cm. 60 di h, cm. 41.5 di larg. mm. 1-3 di sp., rappresenta una figura femminile orante che, per la resa del volto, dei particolari dell’acconciatura e la c…
Synaptic release of zinc from brain slices: factors governing release, imaging, and accurate calculation of concentration.
2006
Cerebrocortical neurons that store and release zinc synaptically are widely recognized as critical in maintenance of cortical excitability and in certain forms of brain injury and disease. Through the last 20 years, this synaptic release has been observed directly or indirectly and reported in more than a score of publications from over a dozen laboratories in eight countries. However, the concentration of zinc released synaptically has not been established with final certainty. In the present work we have considered six aspects of the methods for studying release that can affect the magnitude of zinc release, the imaging of the release, and the calculated concentration of released zinc. We…
Colours of quality: structural (but not pigment) coloration informs about male quality in a polychromatic lizard
2014
Chromatic signals result from the differential absorption of light by chemical compounds (pigment-based colours) and/or from differential scattering of light by integument nanostructures (structural colours). Both structural and pigment-based colours can be costly to produce, maintain and display, and have been shown to convey information about a variety of individual quality traits. Male wall lizards, Podarcis muralis, display conspicuously coloured ventral and lateral patches during ritualized inter- and intrasexual displays: ventral colours (perceived as orange, yellow or white by humans) are pigment based, while the ultraviolet (UV)-blue of the outer ventral scales (OVS), located along …
Differences in conspicuousness between alternative color morphs in a polychromatic lizard
2015
In polychromatic species, differences in conspicuousness among alternative color morphs may affect the costs and benefits relating to signal detectability by primary receivers and unintended observers. Using visual modeling, we studied the conspicuousness of the body coloration in a ventrally polychromatic population of common wall lizards (Podarcis muralis). This species shows a complex color pattern that combines brown dorsal coloration, long-wavelength–biased ventral coloration, and ventrolateral ultraviolet (UV)-blue patches that are used to signal male quality. Considering simultaneously the visual system of P. muralis and lizard predators, we quantified the chromatic and achromatic (i…
Adverse events associated with encorafenib plus binimetinib in the COLUMBUS study: incidence, course and management.
2019
Abstract Background Dual inhibition of the mitogen-activated protein kinase pathway with BRAF/MEK inhibitor (BRAFi/MEKi) therapy is a standard treatment for BRAFV600-mutant metastatic melanoma and has historically been associated with grade III pyrexia or photosensitivity depending on the combination used. The objective of this study was to fully describe adverse events from the COLUMBUS study evaluating the most recent BRAF/MEK inhibitor combination encorafenib+binimetinib. Patients and methods Patients with locally advanced, unresectable or metastatic BRAFV600-mutant melanoma were randomised to receive encorafenib 450 mg once daily plus binimetinib 45 mg twice daily, encorafenib 300 mg on…
