Cet article étudie l’œuvre multimédia de Bruno Latour "Paris Ville invisible", une œuvre qui permet de réfléchir sur une nouvelle manière de pratiquer la théorie sociologique à travers différents types d’images et d’écritures : panoramas, photographies aériennes, plans de la ville, textes écrits, etc. Cette œuvre a comme but de construire, à partir de la « procession » d’images des parcours de la Ville Lumière, une théorie sociologique où le mot théorie ne signifie pas « modèle » ou « contemplation », mais récupère son sens étymologique de « processions d’ambassadeurs allant consulter les oracles ». "Paris Ville Invisible" ne construit pas seulement la biogéographie d’une ville, ni se borne à proposer une nouvelle théorie du social, mais exemplifie, à travers le support multimédia, des nouvelles pratiques du faire scientifique.

Cette étude de cas amène à élargir les notions de "validation" et "valorisation" de l'expérience et des compétences en organisation et ce, au moyen de diverses modalités dont les sources et les logiques sont différentes. Elle vise en outre à présenter une série d'enjeux de la valorisation de l'expérience pour les différents acteurs de l'entreprise qui aboutissent in fine sur un paradoxe qu'il convient de dépasser en intégrant une vision systémique de cette préoccupation émergente.

O striptease que propomos analisar é na verdade o título de uma obra que pertence à produção da artista italiana Benedetta Bonichi. Trata-se de uma composição mista, a meio caminho entre os raios-x e a fotografia. “Striptease” chamou a nossa atenção por várias razões. Com certeza, por seu caráter surpreendente, sendo uma cena erótica e ao mesmo tempo uma radiografia. Mas também por sua estética particular em relação aos outros artistas que desenvolvem uma técnica similar. O propósito de nossos passos é levar em consideração o lugar da obra estudada no espaço de realizações em raio-x artístico, numa perspectiva semiótica. Pretendemos desta maneira chegar à descrição fina de “Striptease, por meio do estabelecimento de um conjunto de formantes plásticos estáveis funcionando como base sobre a qual se correlacionam e se diferenciam os raios-x artísticos estudados. Por isso, desenvolveremos o estudo segundo três etapas gerais. Com a primeira, tentaremos efetuar uma descrição de “Striptease” segundo os três eixos da leitura plástica padrão, tal como foram trabalhados por Jean-Marie Floch: cromático, eidético e topológico. Na segunda etapa, adotaremos o mesmo ponto de vista para a descrição plástica de cinco obras de quatro outros artistas. O interesse da segunda parte consiste em ver como se atualizam as unidades plásticas em cada realização particular, a fim de observar as suas possíveis convergências e divergências. Na última etapa, poderemos considerar a estética de cada obra à luz das atualizações plásticas e das integrações entre elas com outros patamares temáticos. Conseguiremos, finalmente, entender a pertinência e a particularidade de “Striptease” como obra com vocação reflexiva a respeito da prática do raio-x artístico. [less ▲]

The PRDM16 (1p36) gene is rearranged in acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) with t(1;3)(p36;q21), sharing characteristics with AML and MDS with MECOM (3q26.2) translocations. We used fluorescence in situ hybridization to study 39 haematological malignancies with translocations involving PRDM16 to assess the precise breakpoint on 1p36 and the identity of the partner locus. Reverse-transcription polymerase chain reaction (PCR) was performed in selected cases in order to confirm the partner locus. PRDM16 expression studies were performed on bone marrow samples of patients, normal controls and CD34(+) cells using TaqMan real-time quantitative PCR. PRDM16 was rearranged with the RPN1 (3q21) locus in 30 cases and with other loci in nine cases. The diagnosis was AML or MDS in most cases, except for two cases of lymphoid proliferation. We identified novel translocation partners of PRDM16, including the transcription factors ETV6 and IKZF1. Translocations involving PRDM16 lead to its overexpression irrespective of the consequence of the rearrangement (fusion gene or promoter swap). Survival data suggest that patients with AML/MDS and PRDM16 translocations have a poor prognosis despite a simple karyotype and a median age of 65 years. There seems to be an over-representation of late-onset therapy-related myeloid malignancies. [less ▲]

The behavior of Comet Wilson before and after its passage through perihelion, which occurred on April 21, 1987, was studied on the basis of spectrographic and photometric observations. Results pertaining to spectra in the UV, blue, and red regions, and to photometry through narrow-band filters are presented. It is suggested that the fading of Comet Wilson might reflect some general trend in the comet's evolution, or that it could be the result of a geometrical effect associated with the rotation of the comet's nucleus and the presence of discrete active areas on its surface.

Treatment of castrated quail with testosterone (T) reliably activates male copulatory behavior and, at the same time, increases the aromatase activity (AA), the number of aromatase-immunoreactive (ARO-ir) cells and the concentration of aromatase mRNA as measured by RT-PCR in the brain. All these effects can be mimicked by estrogens. The behavioral effects of T can be blocked by a variety of aromatase inhibitors and, in parallel, the AA is strongly inhibited in the preoptic area (POA). We showed recently that the steroidal inhibitor, 4-OH-androstenedione (OHA) markedly decreases the immunostaining density of brain ARO-ir cells while the non-steroidal inhibitor, R76713 (racemic Vorozole; VOR) unexpectedly increased the density of this staining, despite the fact that the enzyme activity was completely inhibited. To generalize these findings and try to identify the underlying mechanism, we compared here the effects of two steroidal (OHA and androstatrienedione [ATD]) and two non-steroidal (VOR and Fadrozole [FAD]) aromatase inhibitors on the aromatase immunostaining and aromatase mRNA concentration in the brain of castrated quail concurrently treated with T. The 4 inhibitors significantly blocked the activation by T of male copulation. The two steroidal inhibitors decreased the immunostaining of brain ARO-ir cells but both VOR and FAD markedly enhanced the density of this staining. In parallel, OHA and ATD completely blocked the T-induced increase in aromatase mRNA concentration, while VOR and FAD had no effect on these RNA concentrations in the POA-anterior hypothalamus and they decreased them only slightly in the posterior hypothalamus. Taken together these results suggest that the inhibition of AA by ATD or OHA and the subsequent removal of locally produced estrogens blocks the synthesis of aromatase presumably at the transcriptional level. By contrast, the two non-steroidal inhibitors tested here block AA but in parallel increase the aromatase immunostaining. This effect does not result from an enhanced transcription and it is therefore speculated that these compounds increase either the translation of the aromatase mRNA or the half-life of the protein itself.

We have previously shown that pirlindole and dehydropirlindole, two monoamine oxidase type-A inhibitors, protect cultured brain cells against iron-induced toxicity through a mechanism unrelated to monoamine oxidase type-A inhibition. The current study was performed to test whether the protective effect of pirlindole and dehydropirlindole could be extended to a nitric oxide (NO)-induced insult. A comparison with other monoamine oxidase inhibitors (brofaromine, moclobemide and deprenyl) and with trolox was made. In a first series of experiments, rat hippocampal or cortical cultured cells were exposed to a drug for 3 h, then 5 muM sodium nitroprusside, a NO donor, was added and the incubation was continued for 16 h. Cell survival assessment showed that pirlindole, dehydropirlindole and trolox significantly protected cultures against NO-induced toxicity in a concentration-dependent manner with respective EC50's of 7, 3 and 17 muM. Similarly, pirlindole, dehydropirlindole or trolox, at a concentration of 50 muM, significantly decreased both intracellular peroxide production and lipoperoxidation. Other drugs were ineffective. In a post-hoc treatment protocol (3- or 6-h pre-incubation in the presence of sodium nitroprusside, then addition of one of the above mentioned compounds), only pirlindole and dehydropirlindole significantly improved cell survival in a concentration-dependent manner with respective EC50'S of 9 and 4 muM. The maximal protection in terms of cell survival was 90% and 78% after 3 and 6 h, respectively. They also reduced the production of both lipoperoxides and endoperoxides. Our results show that pirlindole and dehydropirlindole protect neurons against NO-induced toxicity at pharmacologically relevant concentrations. Moreover, their protective effect is still apparent when they are applied after the start of the insult. Therefore, our preclinical study suggests a new strategy that may be efficient to reduce NO-induced damage in the central nervous system. (C) 2003 Elsevier Science B.V. All rights reserved. [less ▲]

Photoelectric observations of P/Halley were carried out during several weeks between 15 Sept. 1985 and 25 June 1986. All measurements were made using the standard IAU/IHW cometary filters. Large amplitude night-to-night changes over periods of several days superimposed on the general trend of slow brightness variation were seen. Smooth and irregular variations with a range up to 0.2 mag on time scales of several hours were observed. Present photometric scans of comet Halley through the various filters are presented. Successive integrations were made every 5 arc sec, radially from the center out to a distance of 5 arcmin, essentially along the sunward-antisunward direction and in the direction perpendicular to it.
