Rhodopsin and the Others: A Historical Perspective on Structural Studies of G Protein-Coupled Receptors

The role of rhodopsin as a structural prototype for the study of the whole superfamily of G protein-coupled receptors (GPCRs) is reviewed in an historical perspective. Discovered at the end of the nineteenth century, fully sequenced since the early 1980s, and with direct three-dimensional information available since the 1990s, rhodopsin has served as a platform to gather indirect information on the structure of the other superfamily members. Recent breakthroughs have elicited the solution of the structures of additional receptors, namely the beta 1- and beta 2-adrenergic receptors and the A(2A) adenosine receptor, now providing an opportunity to gauge the accuracy of homology modeling and molecular docking techniques and to perfect the computational protocol. Notably, in coordination with the solution of the structure of the A(2A) adenosine receptor, the first "critical assessment of GPCR structural modeling and docking" has been organized, the results of which highlighted that the construction of accurate models, although challenging, is certainly achievable. The docking of the ligands and the scoring of the poses clearly emerged as the most difficult components. A further goal in the field is certainly to derive the structure of receptors in their signaling state, possibly in complex with agonists. These advances, coupled with the introduction of more sophisticated modeling algorithms and the increase in computer power, raise the expectation for a substantial boost of the robustness and accuracy of computer-aided drug discovery techniques in the coming years.

Wealth concentration in the European periphery: Ireland, 1858–2001

Using annual will indexes, a series of wealth concentration is constructed for the north of Ireland on a decennial basis for the period 1858 to 2001. Wealth was highly concentrated at the beginning of the sample period, but inequality falls towards the end of the nineteenth century and continues to fall until the 1970s. However, there does not appear to be a Kuznets-type process at work. Instead, using data on socio-occupational status, it is suggested that the fall in wealth concentration appears to be associated with the demise of the titled classes. Interestingly, similar to the findings of other studies, wealth has become more concentrated since the 1970s.

Figuring Abjection: The Slave Mother in the Early Creole Novel

While twentieth century Caribbean literature in French (particularly post-Césaire) has generated a large body of criticism, writing from the nineteenth century has been largely neglected. This article begins by contextualising the Creole novel of the early nineteenth century in cultural and historical terms, before proceeding to an analysis of two novels published in 1835 by Martinican authors: Outre-mer by Louis de Maynard, and Les Créoles by Jules Levilloux. In the few studies that exist, these texts have been read in opposition to each other in terms of their portrayal of the (male) mulatto; Levilloux has generally been considered the more progressive writer in this regard. However they are in fact in striking harmony in their depiction of the black mother, a figure (in both senses, as her physiognomy is central in her portrayal) who has until now been overlooked. For both writers, the elderly black mother is an abject and wretched creature. She has necessarily to be shown to be repulsive, filthy and morally hideous in old age in order to counteract the fascination she provokes, and to embody a phantasised repellent to the desires of the white male.
