Portraits de Milan par Charles Borromée : la dynamique rigoriste de l’écriture

Les sermons de Charles Borromée composent un portrait ambigu de Milan, à la fois nouvelle Babylone et ville de saint Ambroise. Au-delà de cette ambivalence morale de la ville, lieu commun de la prédication rigoriste, l’article montre la radicalisation progressive des invectives de Borromée, dont le pivot est la grande peste de 1576. Paradoxalement, le divorce entre le pasteur ascète et la ville pécheresse donne lieu à des discours de plus en plus évocateurs de Milan, animée par son goût du luxe, ses marchés, ses tavernes et ses fêtes

Todas as criaturas do mundo: a arte dos mapas como elemento de orientação geográfica

Vague in the outlines and abounding in figures of real or fabulous creatures, the iconography of medieval maps played a significant role in helping users to recognize lands that were virtually unknown to Christendom. In a world with no reliable latitudes and longitudes, the land contours, inhabitants and even certain elements of fauna and flora could become variables of utmost importance for geographic orientation. Notwithstanding the higher levels of precision achieved in their efforts to represent geographic space, the considerable advancements made in latitude determination, and their continuous pursuit of a practical method for the establishment of longitudes, the cartographers of the Age of Discoveries still went to the trouble of depicting notable elements - whether real or imaginary - to help travelers get their bearings around different regions of the globe. As the presence of Europeans continued to expand and an authentic scientific revolution took place in the 17th century, the lengthy notes and eye¿catching representations of nature and local inhabitants soon lost their utility as points of reference on 17th-century maps to become mere accessories of aesthetic and commercial value. The advent of the 18th century consolidated, once and for all, the transformation of such illustrations into essentially decorative elements with no other relevant role to play in mapmaking. In addition to decreasing in number, the figures became more stylized and moved to the borders of the maps as ornamental motifs. Although they often maintained some sort of relation with the geographic space depicted on the map, the motifs chosen could also constitute a rather independent element. In fact, allegories, compositions with a variety of mythological figures, and historical representations were often used to underscore the power of certain political agents

Definitive evidence for an autosomal recessive form of hypohidrotic ectodermal dysplasia clinically indistinguishable from the more common X-linked disorder.

A crucial issue in genetic counseling is the recognition of nonallelic genetic heterogeneity. Hypohidrotic (anhidrotic) ectodermal dysplasia (HED), a genetic disorder characterized by defective development of hair, teeth, and eccrine sweat glands, is usually inherited as an X-linked recessive trait mapped to the X-linked ectodermal dysplasia locus, EDA, at Xq12-q13.1. The existence of an autosomal recessive form of the disorder had been proposed but subsequently had been challenged by the hypothesis that the phenotype of severely affected daughters born to unaffected mothers in these rare families may be due to marked skewing of X inactivation. Five families with possible autosomal recessive HED have been identified, on the basis of the presence of severely affected females and unaffected parents in single sibships and in highly consanguineous families with multiple affected family members. The disorder was excluded from the EDA locus by the lack of its cosegregation with polymorphic markers flanking the EDA locus in three of five families. No mutations of the EDA gene were detected by SSCP analysis in the two families not excluded by haplotype analysis. The appearance of affected males and females in autosomal recessive HED was clinically indistinguishable from that seen in males with X-linked HED. The findings of equally affected males and females in single sibships, as well as the presence of consanguinity, support an autosomal recessive mode of inheritance. The fact that phenotypically identical types of HED can be caused by mutations at both X-linked and autosomal loci is analogous to the situation in the mouse, where indistinguishable phenotypes are produced by mutations at both X-linked (Tabby) and autosomal loci (crinkled and downless)
