Infancy Gospels. Stories and Identities

Even though the canonical Jesus' infancy stories have always provoked great interest in popular culture and in the arts, they have been neglected in research during the last decades due to the relatively late date of their redaction. Since the monograph by Raymond Brown, The Birth of the Messiah , the researchers working on this topic have not attempted to consider its historical impact. In this volume, an international team of scholars proposes firstly a reconsideration of the historical background of these stories in terms of early Jewish and Christian identity quests. Secondly, they deal with early Christian questions on Jesus' infancy and childhood through canonical and apocryphal Gospels including information from Patristic and documentary literature. On the theological level, this volume illustrates the impact that these apocryphal texts, recognized as "useful for the soul" (a phrase coined by François Bovon), have had on the Christian faith.

How market access shapes human capital investment in a peripheral country

Human capital endowment is one of the main factors influencing the level of development of a region. This paper analyses whether remoteness from economic activity has a negative effect on human capital accumulation and, consequently, on economic development. Making use of microdata this research proves that remoteness from economic activity has contributed to explain the divergences in the level of education observed across Spanish provinces over the last 50 years. The effect is significant even when controlling for the improvement of education supply. Nonetheless, the accessibility effect has been petering out since the 1960s due to the decreasing barriers to mobility.

Stent-assisted coiling of bifurcation aneurysms may improve endovascular treatment: a critical evaluation in an experimental model.

BACKGROUND AND PURPOSE: Endovascular treatment of wide-neck bifurcation aneurysms often results in incomplete occlusion or aneurysm recurrence. The goals of this study were to compare results of coil embolization with or without the assistance of self-expandable stents and to examine how stents may influence neointima formation. MATERIALS AND METHODS: Wide-neck bifurcation aneurysms were constructed in 24 animals and, after 4-6 weeks, were randomly allocated to 1 of 5 groups: 1) coil embolization using the assistance of 1 braided stent (n = 5); 2) coil embolization using the assistance of 2 braided stents in a Y configuration (n = 5); 3) coil embolization without stent assistance (n = 6); 4) Y-stenting alone (n = 4); and 5) untreated controls (n = 4). Angiographic results were compared at baseline and at 12 weeks, by using an ordinal scale. Neointima formation at the neck at 12 weeks was compared among groups by using a semiquantitative grading scale. Bench studies were performed to assess stent porosities. RESULTS: Initial angiographic results were improved with single stent-assisted coiling compared with simple coiling (P = .013). Angiographic results at 12 weeks were improved with any stent assistance (P = .014). Neointimal closure of the aneurysm neck was similar with or without stent assistance (P = .908), with neointima covering coil loops but rarely stent struts. Y-stent placement alone had no therapeutic effect. Bench studies showed that porosities can be decreased with stent compaction, but a relatively stable porous transition zone was a limiting factor. CONCLUSIONS: Stent-assisted coiling may improve results of embolization by allowing more complete initial coiling, but these high-porosity stents did not provide a scaffold for more complete neointimal closure of aneurysms.

The bZIP transcription factor Rca1p is a central regulator of a novel CO₂ sensing pathway in yeast.

Like many organisms the fungal pathogen Candida albicans senses changes in the environmental CO(2) concentration. This response involves two major proteins: adenylyl cyclase and carbonic anhydrase (CA). Here, we demonstrate that CA expression is tightly controlled by the availability of CO(2) and identify the bZIP transcription factor Rca1p as the first CO(2) regulator of CA expression in yeast. We show that Rca1p upregulates CA expression during contact with mammalian phagocytes and demonstrate that serine 124 is critical for Rca1p signaling, which occurs independently of adenylyl cyclase. ChIP-chip analysis and the identification of Rca1p orthologs in the model yeast Saccharomyces cerevisiae (Cst6p) point to the broad significance of this novel pathway in fungi. By using advanced microscopy we visualize for the first time the impact of CO(2) build-up on gene expression in entire fungal populations with an exceptional level of detail. Our results present the bZIP protein Rca1p as the first fungal regulator of carbonic anhydrase, and reveal the existence of an adenylyl cyclase independent CO(2) sensing pathway in yeast. Rca1p appears to regulate cellular metabolism in response to CO(2) availability in environments as diverse as the phagosome, yeast communities or liquid culture.
