Le musée français: guerras napoleônicas, coleções artísticas e o longínquo destino de um livro

This paper is about Le Musée Français [The French Museum], a book found in the collection of the library of the Imperial Academy of Fine Arts in Rio de Janeiro. As a catalog of the Napoleon Museum, it bears witness to the reorganization of the arts in Europe as a result of the Napoleonic wars and the project of making Paris a true successor to Athens and Rome, as the center of a new republic of the arts. This process was the object of a dispute where Quatremère de Quincy and Joachim Lebreton played an important role. It was also one of the causes leading to the exile of a group of artists who then helped to lay the foundations for an academic environment in Rio de Janeiro.O artigo trata de Le musée français, livro que fez parte da coleção da biblioteca da Academia Imperial das Belas Artes, no RiodeJaneiro.

PC software for analysis of versatile integrated optical waveguides by polarized Semi-Vectorial Finite Difference Method

International audienceIn this paper, a generic software package that provides an interactive and graphical environment for analysis by polarised semi-vectorial finite difference (SVFD) method of all kinds of integrated optical waveguides, such as buried channel, raised strip, rib, embedded, or ridge waveguides, is described. A coherent design rationale is formulated that takes into account the terms due to the interface between each layer as the basis of modal birefringence in integrated optics. Then, according to the opto-geometric parameters of a given waveguide, the modal propagation constants and the spatial fields patterns are calculated. Three examples regarding typical rib waveguides are dealt with, allowing to discuss the results (effective index values) compared with that of the Galerkin method. As fitted for personal computers, this software should be most useful for designing integrated optics components

Plasmodium falciparum: Molecular analysis of a putative protective antigen, the thermostable 96-kDa protein

International audienceA group of three Plasmodium falciparum antigens of distinct pI, migrating with an apparent MW of 96 kDa has been previously identified as a target of protective immunity both in humans and in monkeys (Jouin et al. 1987, Dubois et al. 1987). These antigens are produced during the late stages of asexual intraerythrocytic development. One of these 96-kDa proteins, the 96 tR, has a pI of 5.25, is thermostable, and is released in the culture supernatant (Jouin et al. 1987). We report here the cloning and expression in Escherichia coli of the gene coding for this antigen. Antibodies raised to the recombinant 96 tR immunoprecipitated exclusively the 96 tR, indicating that the other two antigens of 96 kDa are the product(s) of distinct gene(s). Northern and Southern blots as well as DNA sequencing of the gene showed that the 96 tR antigen is identical to proteins identified in other laboratories as the glycophorin binding protein GBP 130 (Perkins 1984, Ravetch et al. 1985) and Ag 78 (Bianco et al. 1987). The 96-kDa antigen is produced at the trophozoite stage and more actively in the schizonts. It is released in the culture supernatant at the time of schizont rupture, together with two minor products, forming a characteristic triplet. This triplet was also detected in immunoblots of merozoites. An approximate quantification on immunoblots indicated that the largest proportion of the protein is found in the culture supernatant, a minor fraction being loosely associated with merozoites. By immunofluorescence and immunoelectron microscopy, intense signals were observed in the erythrocyte cytoplasm. The 50-amino acid repeats were found in all strains examined, the protein showing some size polymorphism. The antigen was detected in the serum of infected monkeys as well as in that of infected humans

Blood-feeding and immunogenic Aedes aegypti saliva proteins

Mosquito-transmitted pathogens pass through the insect's midgut (MG) and salivary gland (SG). What occurs in these organs in response to a blood meal is poorly understood, but identifying the physiological differences between sugar-fed and blood-fed (BF) mosquitoes could shed light on factors important in pathogens transmission. We compared differential protein expression in the MGs and SGs of female Aedes aegypti mosquitoes after a sugar- or blood-based diet. No difference was observed in the MG protein expression levels but certain SG proteins were highly expressed only in BF mosquitoes. In sugar-fed mosquitoes, housekeeping proteins were highly expressed (especially those related to energy metabolism) and actin was up-regulated. The immunofluorescence assay shows that there is no disruption of the SG cytoskeletal after the blood meal. We have generated for the first time the 2-DE profiles of immunogenic Ae. aegypti SG BF-related proteins. These new data could contribute to the understanding of the physiological processes that appear during the blood meal
