Electron donor-acceptor (EDA) interactions are widely involved in chemistry and their understanding is essential to design new technological applications in a variety of fields ranging from material sciences and chemical engineering to medicine. In this work, we study EDA complexes of carbon dioxide with ketones using several ab initio and Density Functional Theory methods. Energy contributions to the interaction energy have been analyzed in detail using both variational and perturbational treatments. Dispersion energy has been shown to play a key role in explaining the high stability of a non-conventional structure, which can roughly be described by a cooperative EDA interaction.

Purpose. To investigate the spatiotemporal relationship between rod and cone degeneration in the P23H-1 rat. Methods. Control Sprague-Dawley (SD) and P23H-1 rats of ages ranging from P30 to P365 were used. Retinas were processed for whole mounts or cross sections and rods and cones were immunodetected. We used newly developed image analysis techniques to quantify the total population of L/M cones (the most abundant cones in the rat) and analyzed the rings of rod-cone degeneration. Results. In P23H-1 rats, rod degeneration occurs rapidly: first the rod outer segment shortens, at P30 there is extensive rod loss, and by P180 rod loss is almost complete except for the most peripheral retina. The numbers of L/M cones are, at all postnatal ages, lower in P23H-1 rats than in control SD rats, and decrease significantly with age (by P180). Rod and cone degeneration is spatiotemporally related and occurs in rings that appear already at P90 and spread throughout the entire retina. At P180, the rings of rod-cone degeneration are more abundant in the equatorial retina and are larger in the dorsal retina. Conclusions. This work describes for the first time that in the P23H-1 rat, rod and cone degeneration is spatiotemporally related and occurs in rings. Cone loss follows rod loss and starts very soon, even before P30, the first age analyzed here. The characteristics of the rings suggest that secondary cone degeneration is influenced by retinal position and/or other intrinsic or extrinsic factors.

La razón de ser del patrimonio cultural es la posibilidad de que la sociedad disfrute de él, lo conozca y valore. Precisamente, una de las vías de acceso al conocimiento patrimonial es a través de las noticias de prensa, que nos dan cumplida cuenta de informaciones en torno a la custodia, protección y conservación de los bienes culturales --en sentido amplio-- pero también de su destrucción; de los biblioclasmos y memoricidios de que son objeto, por mor de los fanatismos y los integrismos religiosos, entre otros factores. Por ello, además de esa forma de difusión o divulgación indirecta o informal del patrimonio, necesaria por otra parte, resulta esencial establecer y sustentar un vínculo afectivo de la ciudadanía con el patrimonio, a partir de programas didácticos enraizados en los currícula académicos desde la educación primaria hasta los postgrados universitarios.

El período que se abarca se extiende, cronológicamente, a lo largo del primer tercio del siglo XX (1898-1936) y el espacio objeto de estudio se circunscribe a la ciudad de Albacete. El discurso se articula en dos partes: la primera se ocupa de la arquitectura, clasificada por sus tipologías (religiosa, funeraria, asistencial, educativa, institucional, penitenciaria y militar, del ocio, del negocio y residencial), y la segunda se centra en las características de los principales arquitectos que intervinieron en esta época en la ciudad (Julio Carrilero Prat, Ramón Casas Massó, Francisco Fernández Molina, Buenaventura Ferrando Castells, Francisco Manuel Martínez Villena, Agustín Morcillo López, Manuel Muñoz Casayús, Miguel Ortiz e Iribas y Daniel Rubio Sánchez).

The remarkable physicochemical properties of magnetic nanoparticles (MNPs) at the nanoscale have boosted the development of new and promising strategies for the simultaneous diagnosis and treatment of diseases, particularly in cancer therapy Ð the so-called theranostic applications (1). In these strategies, the intrinsic superparamagnetic properties of MNPs have been exploited to gain access into multifunctional systems able to simultaneously perform as enhanced magnetic resonance imaging (MRI) contrast agents, efficient nanocarriers for drug delivery and nanoheaters in magnetic hyperthermia based therapy (2), among others.
