Les auteurs décrivent la femelle de Lutzomyia zeledoni Young et Murillo, 1984 du Groupe Vespertilionis Theodor, 1965. Cette espèce a été capturée en milieu péridomestique en compagnie de Lutzomyia longpalpis Lutz et Neiva, 1912 répertorié pour la première fois du Nicaragua. Il est mis l'accent sur l'importance épidémiologique de cette dernière espèce récoltée en abondance dans plusieurs stations de la façade pacifique.

Granulomatous hypersensitivity to Schistosoma mansoni egg antigens in human Schistosomiasis: I. Granuloma formation and modulation around polyacrylamide antigen-conjugated beads

We have developed an in vitro model of granuloma formation for the purpose of studying the immunological components of delayed type hypersensitivity granuloma formation in patients infected with Schistosoma mansoni. Our data show that 1) granulomatous hypersensitivity can be studied by examining the cellular reactivity manifested as multiple cell layers surrounding the antigen conjugated beads; 2) this reactivity is a CD4 cell dependent, macrophage dependent, B cell independent response and 3) the in vitro granuloma response is antigenically specific for parasite egg antigens. Studies designed to investigate the immune regulation of granulomatous hypersensitivity using purified populations of either CD4 or CD8 T cells have demonstrated the complexity of cellular interactions in the suppression of granulomatous hypersensitivity. The anti-S. mansoni egg immune responses of individual patients with chronic intestinal schistosomiasis can be classified either as soluble egg antigen (SEA) hypersensitive with maximal granulomatous hypersensitivity or SEA suppressive with activation of the T cell suppressor pathway with effective SEA granuloma modulation. Our data suggest that T cell network interactions are active in the generation of effective granuloma modulation in chronic intestinal schistosomiasis patients.

En torno a la obra teatral de Manuel Veiga

Manuel Veiga parece estar creando un universo dramático personal. Muestra una voluntad no sólo de darles la palabra a los marginados de la sociedad haciendo de ellos los protagonistas de sus obras sino que busca recuperar una tradición y una memoria del siglo XX tanto española como mundial en un punto de vista histórico y cultural. Le interesa la memoria en general, su necesidad para algunos, y sus ataduras para otros. Para escenificarla, utiliza la alteración de la temporalidad y el realismo mágico, la fantasía, el sueño y el azar.

Fum i miralls: trobant l'ordre en un món caòtic

El calidoscopi és una joguina que converteix fragments de vidre acolorit en patrons infinitament variats mitjançant l'ús de miralls. Hi ha quelcom satisfactori en els patrons –els necessitem per crear significat, i trobem bellesa en la seva simetria. No obstant, els sistemes complexos desobeeixen les fórmules simples. Per exemple, és impossible descriure una cosa tan prosaica com el comportament del fum mentre ascendeix fent servir les matemàtiques clàssiques. Agafant en préstec idees de diferents disciplines, podem considerar l'alfabetització informacional com una invitació per als nostres estudiants per jugar amb la imprevisible varietat de l'experiència humana i descobrir patrons que els resultin plens de significat.

Globalization and international relations: the Olympic Movement and European Integration

Essay elaborated by Shaelyne Johnson, undergraduate student of Global Studies at the University of California-Santa Barbara, during her internship at CEO-UAB for the academic course 2008/2009. She compares the organisational structure, goals and objectives of the institutions in the Olympic Movement and the European Integration, in order to find connections between both movements which were caused by globalization. The paper begins with an introduction of the changing world nowadays, followed by an overview on the structural similarities in the historical unfolding between these two parallel movements and, before concluding, new means for international relations are considered. This document is available in English through the digital library at the CEO-UAB Portal of Olympic Studies and the digital repository RECERCAT.

International Institutions as Solutions to Underlying Games of Cooperation

This Working Paper was presented at the international workshop "Game Theory in International Relations at 50", organized and coordinated by Professor Jacint Jordana and Dr. Yannis Karagiannis at the Institut Barcelona d'Estudis Internacionals on May 22, 2009. The day-long Workshop was inspired by the desire to honour the ground-breaking work of Professor Thomas Schelling in 1959-1960, and to understand where the discipline International Relations lies today vis-à-vis game theory.

Human schistosomiasis mansoni: studies on in vitro granuloma modulation

Infection with Schistosoma mansoni induces humoral and T cell mediated responses and leads to delayed hipersensitivity that results in granulomatous inflamatory disease around the parasite eggs. Regulation of these responses resulting in a reduction in this anti-egg inflamatory disease is appsrently determined by idiotypic repertoires of the patient, associated with genetic background and multiple external factors. We have previously reported on idiotype/anti-idiotype-receptor transactions in clinical human schistosomiasis. These findings support a hypothesis that anti-SEA cross-reactive idiotypes develop in some patients during the course of a chronic infection and participate in regulation of anti-SEA cellular immune responses. We repport here on experiments wich extend those observations to the regulation of granulomatous hypersensitivity measured by an in vitro granuloma model. T cells from chronic intestinal schistosomiasis patients were stimulated in vitro with anti-SEA idiotypes and assayed in an autologous in vitro granuloma assay for modulation of granuloma formation. These anti-SEA idiotype reactive T cells were capable of regulating autologous in vitro granuloma formation. This regulatory activity, initiated with stimulatory anti-SEA idiotypic antibodies, was antigenically specific and was dependent on the present of intact (F(ab')2 immunoglobulin molecules. The ability to elicit this regulatory activity appears to be dose dependent and is more easily demonstrated in chronically infected intestinal patients or SEA sensitized individuals. These data support the hypothesis that anti-SEA cross reactive idiotypes are important in regulating granulomatous hypersensitivy in chronic intestinal schistosomiasis patients and these cross-reactive idiotypes appear to play a major role in cell-cell interactions which result in the regulation of anti-SEA cellular immune responses.

A new species of Probursata Bravo-Hollis, 1984 (Mogenea: Heteraxinidae: Heteraxininae) parasite of Oligoplites spp. (Osteichthyes: Carangidae) from the coast of the state of Rio de Janeiro, Brazil

Probursata brasiliensis n. sp., a gill filament parasite of carangid fishes, O. palometa (Cuvier), Oligoplites saurus (Bloch & Schneider), and O. saliens (Bloch), from the Brazilian coast, is described and illustrated. The new species differs from Probursata veraecrucis Bravo-Hollis, 1984, the type and only species of this genus by the presence of spines in the auricular expansions of the genital atrium, by the trifurcate supplementary process of the clamp's midsclerite, and by having a larger number of tests and clamps. This is the first record of the genus Probursata Bravo-Hollis, 1984, in the South Atlantic Ocean.

Hechtiella lopesi sp. n. from São Paulo state, Brazil (Siphonaptera: Rhopalopsyllidae)

Descriptions are given of the male and female of Hechtiella lopesi sp. n., collected on Proechimys sp. and Tayra barbara from Boracéia Ecological Station, Salesópolis, São Paulo State, Brazil. The new species is discussed in relation to Hechtiella lakoi and Hechtiella nitidus, species previously included in the genus Polygenis. The name is a tribute to the late Brazilian entomologist, Prof. Hugo de Souza Lopes.
