Mouvement vivant et architecture: la marche, les escaliers chez Émile Jaques-Dalcroze et Adolphe Appia

At the turn of the nineteenth and twentieth centuries, through the eurhythmics of Émile Jaques-Dalcroze, a new relationship between music and movement was established, which closely involved dance and architecture. Our emphasis, here, will be put on the transformations related to space, with regard to the stage reform by Adolphe Appia, Dalcroze’s friend and collaborator. It is through Appia’s drawings, the Rhythmic Spaces, made between 1909 and 1911, that the connection between living movement and architecture will be approached. In particular, one calls in question the status of straight lines, horizontal and vertical, of which the staircases, on the drawings, are emblematic. These lines, contrasting with the curving and serpentines lines that mark the influence of the dancing movement in the paintings from that period, must be understood with respect to the Dalcrozian conception of rhythmic feeling. Aliveness, for him, which is not to be separated from the relationship to measure - itself alive -, can be acquired by varied and complex exercises of marching within the framework of rhythmic education. Through architecture arises a musical conception of space in rupture with the perspectival conception of pictural space, as the former doesn’t dissociate any more mobility and immobility, aliveness and inertia, grace and gravity.At the turn of the nineteenth and twentieth centuries, through the eurhythmics of Émile Jaques-Dalcroze, a new relationship between music and movement was established, which closely involved dance and architecture.

Theodor W. Adorno, Le Conflit des sociologies : théorie critique et sciences sociales

Cet ouvrage témoigne et participe incontestablement de la vitalité qui entoure depuis quelques années la pensée du philosophe allemand Theodor W. Adorno (1903-1969) en France, ce dont il faut se réjouir. Les conditions intellectuelles de réception et probablement aussi le contexte social qui ne dément pas – au contraire – les analyses produites par le théoricien de l’Ecole de Francfort au sortir de la Seconde Guerre mondiale jusqu’à sa mort, arguent en faveur d’une actualité qui fait figure d..

L’inquiétante étrangeté et l’espace architectural

Le texte aborde un cas particulier d’atmosphère, l’inquiétante étrangeté, dans son rapport à l’espace architectural, selon une inflexion phénoménologique soulignant la teneur d’atmosphère (Stimmung) du sentiment éprouvé. Effectuant une relecture du texte éponyme de 1919 de Freud sous cet angle, notamment l’épisode de la promenade dans la petite ville italienne, la réflexion s’engage ensuite dans une approche de la peinture de De Chirico, en particulier le tableau de 1913 La grande Tour. Les écrits du théoricien américain de l’architecture Anthony Vidler viennent à l’appui de la réflexion. La conclusion fait retour sur la maison hantée, au regard d’expériences artistiques plus contemporaines.The text focuses on a particular case of atmosphere, the uncanny, in connection with architectural space, and with a phenomenological accentuation which emphasizes the consistance of atmospheres (Stimmung) of feeling. Proposing first a reading of Freud’s text on the uncanny from this angle, with respect above all to the episode about the walk in a little Italian town, my reflection then pursues an approach of De Chirico’s paintings, and particularly the one called The Big Tower (1913). The writings of the American theoretician of architecture Anthony Vidler sustain the reflection. The conclusion comes back to the haunted house, in relation to more contemporary artistic experiences

Using haematophagous fly blood meals to study the diversity of blood‐borne pathogens infecting wild mammals

Many emerging infectious diseases originate from wild animals, so there is a profound need for surveillance and monitoring of their pathogens. However, the practical difficulty of sample acquisition from wild animals tends to limit the feasibility and effectiveness of such surveys. Xenosurveillance, using blood-feeding invertebrates to obtain tissue samples from wild animals and then detect their pathogens, is a promising method to do so. Here, we describe the use of tsetse fly blood meals to determine (directly through molecular diagnostic and indirectly through serology), the diversity of circulating blood-borne pathogens (including bacteria, viruses and protozoa) in a natural mammalian community of Tanzania. Molecular analyses of captured tsetse flies (182 pools of flies totalizing 1728 flies) revealed that the blood meals obtained came from 18 different vertebrate species including 16 non-human mammals, representing approximately 25% of the large mammal species present in the study area. Molecular diagnostic demonstrated the presence of different protozoa parasites and bacteria of medical and/or veterinary interest. None of the six virus species searched for by molecular methods were detected but an ELISA test detected antibodies against African swine fever virus among warthogs, indicating that the virus had been circulating in the area. Sampling of blood-feeding insects represents an efficient and practical approach to tracking a diversity of pathogens from multiple mammalian species, directly through molecular diagnostic or indirectly through serology, which could readily expand and enhance our understanding of the ecology and evolution of infectious agents and their interactions with their hosts in wild animal communities

Conservative treatment of pediatric thoracic and lumbar spinal fractures

To assess sagittal plane spinopelvic balance and functional outcomes in a pediatric cohort of patients with a thoracic and/or a lumbar fracture treated conservatively. A multicentric study retrospectively reviewed radiological and functional outcomes (mean follow-up 49 months) of 48 patients (mean age 12 years) with thoracic and/or lumbar spinal fractures that occurred between 1996 and 2014. Demographic data and radiological spinopelvic parameters were analyzed. Functional outcome was evaluated by a telephone interview. First, a comparison between the initial and the last follow-up full-spine radiographs was performed for the assessment of bone remodeling and sagittal plane balance. Then, patients were classified into two groups (group 1: Risser≤2 and group 2, Risser>2) to assess the influence of skeletal maturity on the restoration of a correct sagittal balance. A total of 62% of the patients were at skeletal maturity at the final follow-up (Risser 4 and 5). Patients with a Risser grade of 2 or less had a higher remodeling potential. The mean residual local kyphosis in thoracic and lumbar fractures was, respectively, 8.2° and 8.7°. The mean thoracic global kyphosis remains stable at the last follow-up, in contrast to lumbar lordosis, which increased significantly. Sagittal plane global measurements on the basis of the C7-plumbline remained unchanged at the last follow-up. There was no change in the pelvic parameters, except for the sacral slope in the group 1 for patients with a lumbar fracture. The current study confirms a greater correction in younger patients (Risser≤2) in spinal fractures and reported that thoracic fractures have a higher remodeling potential than lumbar fracture. A local kyphosis of almost 10° remained at the last follow-up. However, no deterioration in the sagittal plane balance was found. This suggests compensatory mechanisms in adjacent structures for children and adolescents and excludes the only hypothesis of bone remodeling

Midgut microbiota of the malaria mosquito vector Anopheles gambiae and Interactions with plasmodium falciparum Infection

The susceptibility of Anopheles mosquitoes to Plasmodium infections relies on complex interactions between the insect vector and the malaria parasite. A number of studies have shown that the mosquito innate immune responses play an important role in controlling the malaria infection and that the strength of parasite clearance is under genetic control, but little is known about the influence of environmental factors on the transmission success. We present here evidence that the composition of the vector gut microbiota is one of the major components that determine the outcome of mosquito infections. A. gambiae mosquitoes collected in natural breeding sites from Cameroon were experimentally challenged with a wild P. falciparum isolate, and their gut bacterial content was submitted for pyrosequencing analysis. The meta-taxogenomic approach revealed a broader richness of the midgut bacterial flora than previously described. Unexpectedly, the majority of bacterial species were found in only a small proportion of mosquitoes, and only 20 genera were shared by 80% of individuals. We show that observed differences in gut bacterial flora of adult mosquitoes is a result of breeding in distinct sites, suggesting that the native aquatic source where larvae were grown determines the composition of the midgut microbiota. Importantly, the abundance of Enterobacteriaceae in the mosquito midgut correlates significantly with the Plasmodium infection status. This striking relationship highlights the role of natural gut environment in parasite transmission. Deciphering microbe-pathogen interactions offers new perspectives to control disease transmission.Institut de Recherche pour le Developpement (IRD); French Agence Nationale pour la Recherche [ANR-11-BSV7-009-01]; European Community [242095, 223601]info:eu-repo/semantics/publishedVersio

Fine-Scale Mapping of the 4q24 Locus Identifies Two Independent Loci Associated with Breast Cancer Risk

Background: A recent association study identified a common variant (rs9790517) at 4q24 to be associated with breast cancer risk. Independent association signals and potential functional variants in this locus have not been explored. Methods: We conducted a fine-mapping analysis in 55,540 breast cancer cases and 51,168 controls from the Breast Cancer Association Consortium. Results: Conditional analyses identified two independent association signals among women of European ancestry, represented by rs9790517 [conditional P = 2.51 × 10−4; OR, 1.04; 95% confidence interval (CI), 1.02–1.07] and rs77928427 (P = 1.86 × 10−4; OR, 1.04; 95% CI, 1.02–1.07). Functional annotation using data from the Encyclopedia of DNA Elements (ENCODE) project revealed two putative functional variants, rs62331150 and rs73838678 in linkage disequilibrium (LD) with rs9790517 (r2 ≥ 0.90) residing in the active promoter or enhancer, respectively, of the nearest gene, TET2. Both variants are located in DNase I hypersensitivity and transcription factor–binding sites. Using data from both The Cancer Genome Atlas (TCGA) and Molecular Taxonomy of Breast Cancer International Consortium (METABRIC), we showed that rs62331150 was associated with level of expression of TET2 in breast normal and tumor tissue. Conclusion: Our study identified two independent association signals at 4q24 in relation to breast cancer risk and suggested that observed association in this locus may be mediated through the regulation of TET2. Impact: Fine-mapping study with large sample size warranted for identification of independent loci for breast cancer risk

Le mouvement expressif dansé : Erwin Straus, Walter Benjamin

L’émergence de la danse contemporaine à l’orée du XXe siècle marque le passage d’un régime codifié du geste à un régime qui est expressif du mouvement. Comme le montre Isabelle Launay dans une perspective qui est historique, le geste dansé, jusqu’alors soumis à une rhétorique extérieure, s’affranchit des conventions qui avaient fini par scléroser le ballet à la fin du XIXe siècle. La danse, devenue un art à part entière, trouve son autonomie, libérée de sa tutelle vis-à-vis du théâtre et de l..

Introduction

Une réflexion sur la pensée musicale d’Adorno n’a pas encore été entreprise. Une telle voie a été fermée par les deux types d’approche qui se sont jusqu’à présent partagés le champ de l’interprétation des écrits adorniens sur l’art. D’un côté une approche philosophique qui s’appuie quasi exclusivement sur la Théorie Esthétique, et qui se contente d’occurrences prélevées dans le corpus dit musical afin de confirmer sa démarche. De l’autre, une approche musicologique qui étudie de façon plus ou..
