Cryo-EM structure of ssDNA bacteriophage ΦCjT23 provides insight into early virus evolution.
2022
AbstractThe origin of viruses remains an open question. While lack of detectable sequence similarity hampers the analysis of distantly related viruses, structural biology investigations of conserved capsid protein structures facilitate the study of distant evolutionary relationships. Here we characterize the lipid-containing ssDNA temperate bacteriophage ΦCjT23, which infects Flavobacterium sp. (Bacteroidetes). We report ΦCjT23-like sequences in the genome of strains belonging to several Flavobacterium species. The virion structure determined by cryogenic electron microscopy reveals similarities to members of the viral kingdom Bamfordvirae that currently consists solely of dsDNA viruses wit…
Dopaminergic-GABAergic interplay and alcohol binge drinking
2019
© 2019 Elsevier Ltd The dopamine D 3 receptor (D 3 R), in the nucleus accumbens (NAc), plays an important role in alcohol reward mechanisms. The major neuronal type within the NAc is the GABAergic medium spiny neuron (MSN), whose activity is regulated by dopaminergic inputs. We previously reported that genetic deletion or pharmacological blockade of D 3 R increases GABA A α6 subunit in the ventral striatum. Here we tested the hypothesis that D 3 R-dependent changes in GABA A α6 subunit in the NAc affect voluntary alcohol intake, by influencing the inhibitory transmission of MSNs. We performed in vivo and ex vivo experiments in D 3 R knockout (D 3 R −/− ) mice and wild type littermates (D 3 …

A 0535+26 in the August/September 2005 outburst observed by RXTE and INTEGRAL
2007
In this Letter we present results from INTEGRAL and RXTE observations of the spectral and timing behavior of the High Mass X-ray Binary A 0535+26 during its August/September 2005 normal (type I) outburst with an average flux F(5-100keV)~400mCrab. The search for cyclotron resonance scattering features (fundamental and harmonic) is one major focus of the paper. Our analysis is based on data from INTEGRAL and RXTE Target of Opportunity Observations performed during the outburst. The pulse period is determined. X-ray pulse profiles in different energy ranges are analyzed. The broad band INTEGRAL and RXTE pulse phase averaged X-ray spectra are studied. The evolution of the fundamental cyclotron …
The pre-outburst flare of the A 0535+26 August/September 2005 outburst
2008
We study the spectral and temporal behavior of the High Mass X-ray Binary A 0535+26 during a `pre-outburst flare' which took place ~5 d before the peak of a normal (type I) outburst in August/September 2005. We compare the studied behavior with that observed during the outburst. We analyse RXTE observations that monitored A 0535+26 during the outburst. We complete spectral and timing analyses of the data. We study the evolution of the pulse period, present energy-dependent pulse profiles both at the initial pre-outburst flare and close to outburst maximum, and measure how the cyclotron resonance-scattering feature (hereafter CRSF) evolves. We present three main results: a constant period P=…

Fluctuacions quàntiques en cavitats òptiques no lineals
2011
Aquesta tesi doctoral tracta sobre alguns aspectes de la generació de llum comprimida en cavitats no lineals tipus Kerr. La llum comprimida és un dels tipus de "llum quàntica", un tipus de llum que posseeix propietats relatives a les fluctuacions en els valors esperats dels seus observables de les què no es pot donar compte si no és mitjançant l'ús de la teoria quàntica de la radiació. L'estat buit del camp electromagnètic posseeix fluctuacions d'acord amb el principi d'incertitud d'Heisenberg. En aquest context, denominem llum comprimida a un tipus de radiació que presenta en algun dels seus observables fluctuacions menors que les corresponents a l'estat buit. Aquest tipus especial de radi…
Modelización de dispositivos optoelectrónicos microestructurados. Métodos modales
2003
En esta tesis se ha desarrollado un método de representación modal tridimensional para la obtención del espectro de modos de cavidades inhomogéneas. El método se fundamenta en el hecho de que los modos de una cavidad inhomogénea son solución de una ecuación de valores propios, cuyo operador es autoadjunto. Con ello, la solución de un problema auxiliar sencillo puede proporcionar una base ortogonal para representar matricialmente las ecuaciones diferenciales de otros problemas de mayor complejidad. De esta forma, el problema se reduce a la solución de un sistema algebraico de valores propios.El método propuesto permite calcular los modos de sistemas inhomogéneos con distribuciones arbitraria…

Transition form factors of the N(*()1535) as a dynamically generated resonance
2007
We discuss how electromagnetic properties provide useful tests of the nature of resonances, and we study these properties for the N*(1535) which appears dynamically generated from the strong interaction of mesons and baryons. Within this coupled channel chiral unitary approach, we evaluate the A_1/2 and S_1/2 helicity amplitudes as a function of Q^2 for the electromagnetic N*(1535) to gamma* N transition. Within the same formalism we evaluate the cross section for the reactions gamma N to eta N. We find a fair agreement for the absolute values of the transition amplitudes, as well as for the Q^2 dependence of the amplitudes, within theoretical and experimental uncertainties discussed in the…
