The Biblioteca de Catalunya: working for the present and the future

The Biblioteca de Catalunya (BC) was created in 1907 by the Institut d’Estudis Catalans (IEC). In 1914 the Mancomunitat de Catalunya gave the library its condition of cultural and public service, open to researchers and scholars. The library underwent several changes as a consequence of political events, along the most of 20th century. In 1981 it was recognized by law as national library and it recovered its foundational aim of gathering, preserving and disseminating the bibliographical output of Catalonia and the production related with the Catalan linguistic field. As the proud host of ANADP2, the BC wants to show the attendees to the conference how, since 2004, has positioned itself to face the challenge of the new informational and technological paradigm. The library strategy for oncoming years includes giving open and free access online to the digitization of many of his collections through the portals MDC (Digital Memory of Catalonia), ARCA (Old Catalan Serials Archive) and Google Books project; the creation of the Web Archive of Catalonia and, as the last step in the consolidation of its policy, a high-security preserving repository named COFRE, based on the international guidelines and initiatives and the experience of the BC itself.

Parachlamydia acanthamoebae in domestic cats with and without corneal disease.

Corneal samples of cats with and without corneal diseases were screened with a pan-Chlamydiales PCR and specific PCRs for Parachlamydia, Protochlamydia, Chlamydophila felis, Acanthamoeba and feline herpesviruses (FHV-1). Several corneal samples tested positive for Parachlamydia and related Chlamydiales, indicating cat exposure to these intracellular bacteria.

Postmortem angiography after vascular perfusion with diesel oil and a lipophilic contrast agent.

OBJECTIVE: The objective of our study was to establish optimal perfusion conditions for high-resolution postmortem angiography that would permit dynamic visualization of the arterial and venous systems. MATERIALS AND METHODS: Cadavers of two dogs and one cat were perfused with diesel oil through a peristaltic pump. The lipophilic contrast agent Lipiodol Ultra Fluide was then injected, and angiography was performed. The efficiency of perfusion was evaluated in the chick chorioallantoic membrane. RESULTS: Vessels could be seen up to the level of the smaller supplying and draining vessels. Hence, both the arterial and the venous sides of the vascular system could be distinguished. The chorioallantoic membrane assay revealed that diesel oil enters microvessels up to 50 microm in diameter and that it does not penetrate the capillary network. CONCLUSION: After establishing a postmortem circulation by diesel oil perfusion, angiography can be performed by injection of Lipiodol Ultra Fluide. The resolution of the images obtained up to 3 days after death is comparable to that achieved in clinical angiography.

Good practice for dialogue and communication as strategic principle for policing political manifestations in Europe (GODIAC):the anthology

The volume is divided into two parts; the fi rst deals with issues related to the police, and the second addresses issues related to demonstrators and protesters. We hope that this volume will provide further insight into issues associated with policing at major events and shed light on the complexity of the organisations, motives, and strategies in play whenever protester groups are involved.

Development of projections from auditory to visual areas in the cat.

In newborn kittens, cortical auditory areas (including AI and AII) send transitory projections to ipsi- and contralateral visual areas 17 and 18. These projections originate mainly from neurons in supragranular layers but also from a few in infragranular layers (Innocenti and Clarke: Dev. Brain Res. 14:143-148, '84; Clarke and Innocenti: J. Comp. Neurol. 251:1-22, '86). The postnatal development of these projections was studied with injections of anterograde tracers (wheat germ agglutinin-horseradish peroxidase [WGA-HRP]) in AI and AII and of retrograde tracers (WGA-HRP, fast blue, diamidino yellow, rhodamine-labeled latex beads) in areas 17 and 18. It was found that the projections are nearly completely eliminated in development, this, by the end of the first postnatal month. Until then, most of the transitory axons seem to remain confined to the white matter and the depth of layer VI; a few enter it further but do not appear to form terminal arbors. As for other transitory cortical projections the disappearance of the transitory axons seems not to involve death of their neurons of origin. In kittens older than 1 month and in normal adult cats, retrograde tracer injections restricted to, or including, areas 17 and 18 label only a few neurons in areas AI and AII. Unlike the situation in the kitten, nearly all of these are restricted to layers V and VI. A similar distribution of neurons projecting from auditory to visual areas is found in adult cats bilaterally enucleated at birth, which suggests that the postnatal elimination of the auditory-to-visual projection is independent of visual experience and more generally of information coming from the retina.

Man-bites-dog business cycles

The newsworthiness of an event is partly determined by how unusual it isand this paper investigates the business cycle implications of this fact. In particular, weanalyze the consequences of information structures in which some types of signals are morelikely to be observed after unusual events. Such signals may increase both uncertainty anddisagreement among agents and when embedded in a simple business cycle model, can helpus understand why we observe (i) occasional large changes in macro economic aggregatevariables without a correspondingly large change in underlying fundamentals (ii) persistentperiods of high macroeconomic volatility and (iii) a positive correlation between absolutechanges in macro variables and the cross-sectional dispersion of expectations as measuredby survey data. These results are consequences of optimal updating by agents when theavailability of some signals is positively correlated with tail-events. The model is estimatedby likelihood based methods using individual survey responses and a quarterly time seriesof total factor productivity along with standard aggregate time series. The estimated modelsuggests that there have been episodes in recent US history when the impact on outputof innovations to productivity of a given magnitude was more than eight times as largecompared to other times.

Long-distance wolf recolonization of France and Switzerland inferred from non-invasive genetic sampling over a period of 10 years

In the early 1900s, the wolf (Canis lupus) was extirpated from France and Switzerland. There is growing evidence that the species is presently recolonizing these countries in the western Alps. By sequencing the mitochondrial DNA (mtDNA) control region of various samples mainly collected in the field (scats, hairs, regurgitates, blood or tissue; n = 292), we could (1) develop a non-invasive method enabling the unambiguous attribution of these samples to wolf, fox (Vulpes vulpes) or dog (Canis familiaris), among others; (2) demonstrate that Italian, French and Swiss wolves share the same mtDNA haplotype, a haplotype that has never been found in any other wolf population world-wide. Combined together, field and genetic data collected over 10 years corroborate the scenario of a natural expansion of wolves from the Italian source population. Furthermore, such a genetic approach is of conservation significance, since it has important consequences for management decisions. This first long-term report using non-invasive sampling demonstrates that long-distance dispersers are common, supporting the hypothesis that individuals may often attempt to colonize far from their native pack, even in the absence of suitable corridors across habitats characterized by intense human activities.

Cellular and viral factors implicated in persistent infection in canine distemper virus

Summary SLAM (signalling lymphocyte activation molecule, CD150) serves as a cellular receptor for different morbiliviruses, including measles virus and canine distemper virus. Laboratory cell lines that do not express dog SLAM are therefore quite refractory to infection by wildtype CDV. SLAM expression is not only required for CDV virion attachment, but also for the establishment of cytolytic infection characterized by syncytia formation. In order to determine if SLAM has a direct influence on CDV replication, we compared wild-type and mutated SLAM variants for their capacity to influence viral polymerase activity and syncytia formation. Deletion of immunoreceptor tyrosine-based signalling motif (ITSM) in the cytoplasmic tail of SLAM did not seem to influence viral replication, viral polymerase activity or cell-to cell fusion. Instead, it was the level of cell surface expression of SLAM, which was important. Additional experiments corroborated the importance of SLAM for efficient cell-to cell fusion: Both SLAM, as well as viral fusion (F) and attachment (H) glycoproteins, were found to be required for efficient cell-to-cell fusion, which, in turn, enhanced the activity of the viral polymerase and, viral replication. Wild-type A75/17 canine distemper virus (CDV) strain is known to induce a persistent infection in the central nervous system and in dog footpad keratinocytes in vivo. Recently, it has been shown that the A75/17 virus could also infect canine footpad keratinocytes (CFKs) in vitro. CFK infection with A75/17 was initially inefficient and produced very little virus progeny, however, after only three passages the adapted virus produced more progeny and induced limited syncytia formation. Sequence comparison between the A75/17 and the CFKadapted A75/17-K virus revealed three amino acid differences, one in the phosphoprotein (P), one in the matrix protein (M) and one in the H protein. In order to identify viral determinants of A75/17-K adaptation, recombinant viruses containing one, two or three nucleotides substitutions were analyzed. The amino acid substitution in the M protein was without effect on viral particle formation. In contrast, the amino acid substitution in the cytoplasmic tail of H protein was clearly important for syncytia formation. Concerning the mutation in the P protein, it led to an increase in viral replication. However, we cannot rule out that the observed effect is due to the amino acid substitutions in the overlapping accessory proteins C and V, also affected by the P mutation. The adaptation of wild-type CDV strains to cell culture almost always involves modifications of M protein. In order to understand the influence of these modifications, we tested recombinant A75/17 viruses bearing different M proteins. Preliminary results demonstrated that the M protein from the Vero-adapted strain reduced syncytia formation. Future studies will focus on the M mRNA and protein stability, its expression level, localisation and its effect on viral particles formation and on the phenotype of infection. Résumé La protéine SLAM (signalling lymphocyte activation molecule ou CD150) est utilisée comme récepteur cellulaire par les morbillivirus parmi lesquels on trouve le virus de la rougeole (VR) ainsi que le virus de la maladie de Carré (CDV). Les lignées cellulaires qui n'expriment pas la protéine SLAM du chien à leur surface sont réfractaires à l'infection par les souches sauvages de CDV. Le récepteur SLAM n'est pas seulement requis pour l'attachement du virion à la surface de la cellule, mais il participe également de façon active à l'établissement d'une infection cytolytique à travers la formation de syncytia. Afin de déterminer si la protéine SLAM exerce une influence directe sur la réplication virale du virus de la maladie de Carré, nous avons généré différentes protéines tronquées de SLAM et comparé leurs capacités à influencer l'activité de la polymérase ainsi que la formation de syncytia. Nos résultas ont montré que la réplication virale, l'activité de la polymérase ainsi que la fusion cellulaire ne semblent pas être influencées par les délétions dans les régions cytoplasmiques du récepteur SLAM. Cependant, ces délétions agissent sur l'expression de la protéine SLAM à la surface des cellules. Les expériences additionnelles ont permis de souligner l'importance de la protéine SLAM dans le phénomène de fusion entre cellules. En effet, la protéine SLAM ainsi que les deux glycoprotéines virales F et H sont requises pour la formation de syncytia, laquelle induit une augmentation de l'activité de la polymérase ainsi que de la réplication virale. La souche virulente A75/17 du virus, de la Maladie de Carré est connue pour induire une infection persistante au niveau du système nerveux central ainsi que dans les kératinocytes de pattes chez le chien. Des études récentes ont montré que des cultures primaires de kératinocytes de chien pouvaient aussi êtres infectées par la souche A75/17 de CDV. En effet, le virus induit une infection persistante en produisant très peu de progéniture. Cependant, trois passages du virus sauvage A75/17 dans ces cultures aboutissent à la sélection d'un virus produisant plus de progéniture et favorisant la formation limitée de syncytia. La comparaison des séquences génomique entre la souche A75/17 et la souche adaptée A75/17-K montre une différence de trois nucléotides. La première mutation, située dans le gène P, modifie la phosphoprotéine (P) ainsi que les protéines V et C. La deuxième se situe dans le gène de la protéine matricielle (M) et la dernière dans celui de la protéine d'attachement (H). Afin de déterminer les facteurs viraux impliqués lors de l'adaptation virale dans la culture primaire de kératinocytes, des virus recombinants contenant une, deux ou trois de ces mutations ont été analysés. La substitution d'un acide aminé dans la protéine M reste sans effet sur la production de particules virales. En revanche, la substitution d'un acide aminé dans la queue cytoplasmique de la protéine H s'avère clairement importante pour la formation de syncytia. Quant à la mutation dans le gène P, elle permet une augmentation de la réplication virale. Cependant, nous ne pouvons pas écarter l'hypothèse que l'augmentation de la réplication virale soit due aux substitutions d'un acide aminé dans les protéines accessoires V et C qui sont, elles aussi, affectées par la mutation dans le gène P. L'adaptation des souches sauvages de CDV aux cultures de cellules induit presque toujours des modifications de la protéine matricielle M. Afin de comprendre l'influence de ces modifications, nous avons testé 'des virus A75/17 recombinants contenant différentes protéines M. Les résultats préliminaires ont démontré que la protéine M de la souche adaptée aux cellules Vero réduisait la formation de syncytia. Les études futures seront axées sur la stabilité de l'ARN messager, celle de la protéine M, de son niveau d'expression, de sa localisation cellulaire et de son effet sur la formation de particules virale ainsi que sur le phénotype de l'infection.

The importance of myth in contemporary art: myth, poetry and women

This project is intended to prove the prevalent importance of myth in contemporary art and, more specifically, to highlight how myth and poetry have shaped and reflected ideas of womanhood over time. A selection of significant literary periods, authors and works from the Renaissance to our days have been chosen in order to provide a wide scope of the evolution that the portrayal of women has undergone. Special attention has been paid to the way in which a group of selected poets have contributed to the construction and deconstruction of traditional Judeo-Christian and Greco-Roman myths strongly attached to patterns of male dominance.
