México y el surrealismo: Leonora Carrington y el laberinto fantástico de Xilitla
2018
En 1965 Leonora Carrington pinta un mural en una de las paredes del laberíntico Castillo de Xilitla, muy cerca de la surreal obra arquitectónica creada por Edward James en selva de la Huasteca potosina (Xilitla, México). El encuentro con el extravagante mecenas y coleccionista de arte, el inglés Edward James, resulta crucial en su recorrido artístico y lleva a la realización de la única obra mural creada por Carrington: La minotaura. En este mural la artista representa una de las insólitas y extremadamente seductoras criaturas híbridas que habitan su espacio pictórico. El ensayo sigue analizando la compleja producción de la la artista inglesa que desde 1942 vive in México. En particular est…
Role of Solvent on Protein-Matrix Coupling in MbCO Embedded in Water-Saccharide Systems: A Fourier Transform Infrared Spectroscopy Study
2006
AbstractEmbedding protein in sugar systems of low water content enables one to investigate the protein dynamic-structure function in matrixes whose rigidity is modulated by varying the content of residual water. Accordingly, studying the dynamics and structure thermal evolution of a protein in sugar systems of different hydration constitutes a tool for disentangling solvent rigidity from temperature effects. Furthermore, studies performed using different sugars may give information on how the detailed composition of the surrounding solvent affects the internal protein dynamics and structural evolution. In this work, we compare Fourier transform infrared spectroscopy measurements (300–20K) o…
Additive effects of enhanced ambient ultraviolet B radiation and increased temperature on immune function, growth and physiological condition of juve…
2009
Climate change models predict increased ultraviolet B (UVB) radiation levels due to stratospheric ozone depletion and global warming. In order to study the impact of these two environmental stressors acting simultaneously on the physiology of fish, Atlantic salmon parr were exposed, for 8 weeks in outdoor tanks, to different combinations of UVB radiation (depleted and enhanced) and temperature (standard rearing temperature of 14 °C or 19 °C). The immune function (plasma IgM, lysozyme activity and complement bacteriolytic activity), growth (body weight) and physiological condition (haematocrit and plasma protein concentration) of the fish were determined. Increased UVB level, regardless of w…
Poly(N-isopropylacrylamide)-gated Fe3O4/SiO2 core shell nanoparticles with expanded mesoporous structures for the temperature triggered release of ly…
2015
Core-shell nanoparticles comprised of Fe3O4 cores and a mesoporous silica shell with an average expanded pore size of 6.07 nm and coated with a poly(N-isopropylacrylamide) (PNIPAM) layer (CS MSNs EP PNIPAM) were prepared and characterized. The nanoparticles was loaded with (Ru(bipy)3 2+) dye or an antibacterial enzyme, lysozyme, to obtain CS MSNs EP PNIPAM Ru(bipy)3 2+ and CS MSNs EP PNIPAM Lys, respectively. The lysozyme loading was determined to be 160 mg/g of nanoparticle. It was seen that Ru(bipy)3 2+ and lysozyme release was minimal at a room temperature of 25 ºC while at physiological temperature (37 º C), abrupt release was observed. The applicability of the CS MSNs EP PNIPAM Lys was…
Nuevas consideraciones sobre el pintor Francesco Pagano
2010
En este artículo se presentan dos documentos inéditos relacionados con la pintura al fresco de los ángeles músicos de la catedral de Valencia realizada por Francesco Pagano y Pablo de San Leocadio. Se trata de un inventario de bienes perteneciente a Francesco Pagano y un documento relativo a los andamios utilizados para la ejecución de los frescos. Su interpretación permite reconsiderar el papel asignado a ambos pintores y aporta nuevas hipótesis sobre el proceso de ejecución de esta obra. (A)
Centri storici manomessi: “antichi” come nuovi!
2012
The chapter presents the results of urban planning in Italy since 1950 and introduces the theories developed by Muratori and Caniggia for the restoration of historical centers. The paper critically shows some examples of typological restoration and introduces the debate that has developed around the outcomes of interventions.

Influence of ligand density on the properties of metal-chelate affinity supports.
1993
A new procedure has been developed to immobilize iminodiacetic acid (IDA) onto the surface of silica supports, such as LiChrospher Si-1000 and 1.5-microns nonporous silica, for use in high-performance immobilized metal affinity chromatography (HPIMAC) of proteins. This IDA immobilization method has been achieved through the synthesis of a new silylation reagent, 1-(iminodiacetic acid di-tert-butylester)-3-glycidoxy-propyltrimethoxysilane (IDA-silane). Various modified silicas of different ligand densities have been prepared by using mixtures between 1 and 100% of the IDA-silane diluted with the corresponding 3-glycidoxy-propyltrimethoxysilane (GLYMO-silane). Frontal analysis was used with t…

Interactions of lysozyme with hydrophilic and hydrophobic polymethacrylate stationary phases in reversed phase chromatography (RPC)
1994
Two silicas, one with a mean pore diameter of 30 nm and the other non-porous, were coated with polymethacrylates of increasing hydrophobicity in the sequence: poly-2-hydroxyethylmethacrylate (P2HEMA)1 polyethylmethacrylate (PEMA) and poly-n-octylmethacrylate (POMA). Association constants, Kass, between lysozyme and the coated silicas were determined by means of frontal analysis, and the apparent heats of adsorption, delta Happ, by means of microcalorimetry. Using Kass and delta Happ the changes in the apparent free energy, delta Gapp, and in the apparent entropy, delta Sapp, were calculated at a concentration of lysozyme < 10 mumol/l. The association between the lysozyme and the coated sili…
