The Outlaw Pirate Heroine, An Analysis of a Durgā Figure in a 1935 Prabhat Film

(Résumé de l'ouvrage) She kills and destroys. She causes illness and disaster. The wild goddess evokes fear and terror. People worship her with blood-sacrifices and alcohol in order to appease her rage, but also in order to participate in her power for she is at once a force of destruction and a force of regeneration, of life, and of sexuality. Her creative violence reflects the ambivalent power of nature. The idea of frightening goddesses is preserved in regionally different forms throughout South Asia. The Institute for the Science of Religions, University of Berne, and the Museum of Anthropology of the University of Zurich, coordinated a symposium on wild goddesses in India and Nepal. The papers and reports on ongoing research presented at this symposium are published in this volume.

Molecular evidence for a functional ecdysone signaling system in Brugia malayi.

BACKGROUND: Filarial nematodes, including Brugia malayi, the causative agent of lymphatic filariasis, undergo molting in both arthropod and mammalian hosts to complete their life cycles. An understanding of how these parasites cross developmental checkpoints may reveal potential targets for intervention. Pharmacological evidence suggests that ecdysteroids play a role in parasitic nematode molting and fertility although their specific function remains unknown. In insects, ecdysone triggers molting through the activation of the ecdysone receptor: a heterodimer of EcR (ecdysone receptor) and USP (Ultraspiracle). METHODS AND FINDINGS: We report the cloning and characterization of a B. malayi EcR homologue (Bma-EcR). Bma-EcR dimerizes with insect and nematode USP/RXRs and binds to DNA encoding a canonical ecdysone response element (EcRE). In support of the existence of an active ecdysone receptor in Brugia we also cloned a Brugia rxr (retinoid X receptor) homolog (Bma-RXR) and demonstrate that Bma-EcR and Bma-RXR interact to form an active heterodimer using a mammalian two-hybrid activation assay. The Bma-EcR ligand-binding domain (LBD) exhibits ligand-dependent transactivation via a GAL4 fusion protein combined with a chimeric RXR in mammalian cells treated with Ponasterone-A or a synthetic ecdysone agonist. Furthermore, we demonstrate specific up-regulation of reporter gene activity in transgenic B. malayi embryos transfected with a luciferase construct controlled by an EcRE engineered in a B. malayi promoter, in the presence of 20-hydroxy-ecdysone. CONCLUSIONS: Our study identifies and characterizes the two components (Bma-EcR and Bma-RXR) necessary for constituting a functional ecdysteroid receptor in B. malayi. Importantly, the ligand binding domain of BmaEcR is shown to be capable of responding to ecdysteroid ligands, and conversely, ecdysteroids can activate transcription of genes downstream of an EcRE in live B. malayi embryos. These results together confirm that an ecdysone signaling system operates in B. malayi and strongly suggest that Bma-EcR plays a central role in it. Furthermore, our study proposes that existing compounds targeting the insect ecdysone signaling pathway should be considered as potential pharmacological agents against filarial parasites.

Le «corps» du texte néotestamentaire dans les films Ben-Hur (1925) et Golgotha (1935)

L'article se propose de discuter la question des modalités de la référence aux évangiles au cinéma en s'attachant à l'étude de la composante verbale et de ses liens avec la représentation de la figure christique dans deux films: le premier, Ben-Hur (Fred Niblo, 1925), est une superproduction produite par Hollywood à l'époque de l'apogée du muet; le second, Golgotha (1935), est réalisé par le cinéaste français Julien Duvivier durant les premières années de la généralisation du parlant. D'un côté l'écrit (sous forme d'intertitres), de l'autre la profération orale d'un texte. Le rapprochement proposé entre ces deux films tient à la façon dont la citation néotestamentaire participe à la construction par le film de la figure de Jésus, ou plutôt à la mise à distance de celle-ci, constamment rejetée dans une forme de hors-champ.

Expérimentation et clinique électroencéphalographiques entre physiologie, neurologie et psychiatrie (Suisse, 1935-1965)

The electroencephalogram (EEG), invented by the German psychiatrist Hans Berger in 1924, reached the neurophysiological laboratories and several clinical contexts in the mid-30s. In Switzerland, some skeptical physiologists and enthusiastic psychiatrists paved the way for its integration, but it was only after the Second World War that an emerging field of epileptology became part of a process of technological and epistemological innovation which raised great expectations and produced a large body of research at the crossroads of physiology, neurology and psychiatry. An informal network was created, characterized by clinical, scientific and local institutional cultures. The EEG also made it possible to detect some clinical entities, not however without transforming them, as in the case of epilepsy. Some attempts to probe psychiatric diseases and subjects with the EEG are described as negotiated relationships between clinical observations, subjective manifestations or symptoms and inscriptions of a spontaneous or elicited electrical brain activity. These attempts shape a clinical and experimental cerebral subject, which is analyzed in this article from the point of view of its technical aspects and the concrete procedures on which it depends.

Detection of Leishmania RNA virus in Leishmania parasites.

BACKGROUND: Patients suffering from cutaneous leishmaniasis (CL) caused by New World Leishmania (Viannia) species are at high risk of developing mucosal (ML) or disseminated cutaneous leishmaniasis (DCL). After the formation of a primary skin lesion at the site of the bite by a Leishmania-infected sand fly, the infection can disseminate to form secondary lesions. This metastatic phenotype causes significant morbidity and is often associated with a hyper-inflammatory immune response leading to the destruction of nasopharyngeal tissues in ML, and appearance of nodules or numerous ulcerated skin lesions in DCL. Recently, we connected this aggressive phenotype to the presence of Leishmania RNA virus (LRV) in strains of L. guyanensis, showing that LRV is responsible for elevated parasitaemia, destructive hyper-inflammation and an overall exacerbation of the disease. Further studies of this relationship and the distribution of LRVs in other Leishmania strains and species would benefit from improved methods of viral detection and quantitation, especially ones not dependent on prior knowledge of the viral sequence as LRVs show significant evolutionary divergence. METHODOLOGY/PRINCIPAL FINDINGS: This study reports various techniques, among which, the use of an anti-dsRNA monoclonal antibody (J2) stands out for its specific and quantitative recognition of dsRNA in a sequence-independent fashion. Applications of J2 include immunofluorescence, ELISA and dot blot: techniques complementing an arsenal of other detection tools, such as nucleic acid purification and quantitative real-time-PCR. We evaluate each method as well as demonstrate a successful LRV detection by the J2 antibody in several parasite strains, a freshly isolated patient sample and lesion biopsies of infected mice. CONCLUSIONS/SIGNIFICANCE: We propose that refinements of these methods could be transferred to the field for use as a diagnostic tool in detecting the presence of LRV, and potentially assessing the LRV-related risk of complications in cutaneous leishmaniasis.

Ville, tourisme et transport : la Compagnie du chemin de fer Lausanne-Ouchy (1869-1914)

Inauguré le 16 mars 1877, le chemin de fer entre Lausanne et le petit port touristique d'Ouchy constitue une entreprise aux dimensions techniques et financières pharaoniques. Premier funiculaire à câble de Suisse, le Lausanne-Ouchy est aussi le premier au monde à être équipé d'un système de traction hydraulique. L'objectif de cette contribution n'est toutefois pas d'analyser les conditions de réalisation de cet exploit technologique, mais la naissance et l'évolution d'une compagnie de transport étroitement liée à l'établissement du système touristique lausannois. La demande de mobilité créée par l'afflux d'étrangers et l'apport des milieux touristiques au capital sont en effet indispensables à la création et à la survie de l'entreprise, dont la santé financière reste longtemps problématique. En retour, le funiculaire modifie le système de transport régional et national, donnant d'importantes impulsions au développement touristique.
