Petit traité de désobéissance féministe. A l'usage de celles et ceux qui ne viennent ni de mars ni de Vénus

Notre société incite hommes et femmes, dès leur plus jeune âge, à adopter des caractères et des comportements stéréotypés, sous peine de ne plus être reconnus comme de « vrais » hommes et de « vraies » femmes. Ce petit traité de désobéissance féministe a pour ambition de s'interroger sur les représentations contemporaines des sexes de manière à permettre à celles et ceux qui ne viennent ni de Mars, ni de Vénus de désobéir à cette « police des genres ». A la voix de l'auteure s'ajoutent celles d'une cinquantaine de personnalités - journalistes, politicien-ne-s, écrivain-e-s, professeur-e-s, etc. -, qui dévoilent leur rapport au féminisme.

Dion Chrysostome et Euripide : de l'usage pédagogique d'un auteur tragique

Le théâtre d'Euripide possède une importance et un statut particuliers à l'époque impériale. Ce travail examine la représentation du Tragique et de son oeuvre dans le corpus attribué au sophiste Dion Chrysostome. Il met en évidence certaines singularités du théâtre euripidéen et de sa réception : importance des personnages féminins, popularité de ce théâtre (qui était également diffusé par les spectacles de pantomimes), dimensions philosophiques et politiques, qui se prêtent à une exploitation pédagogique. La croyance populaire attachée aux mythes véhiculés par Euripide, dotée d'un aspect religieux, en fait un bon instrument pour une communication efficace, qui vise un large public.

Altered structural connectivity in patients with medial temporal lobe epilepsy: A Diffusion Spectrum Imaging and Graph Analysis study

In this study we investigated the effect of medial temporal lobe epilepsy (MTLE) on the global characteristics of brain connectivity estimated by topological measures. We used DSI (Diffusion Spectrum Imaging) to construct a connectivity matrix where the nodes represents the anatomical ROIs and the edges are the connections between any pair of ROIs weighted by the mean GFA/FA values. A significant difference was found between the patient group vs control group in characteristic path length, clustering coefficient and small-worldness. This suggests that the MTLE network is less efficient compared to the network of the control group.

Differential T cell receptor photoaffinity labeling among H-2Kd restricted cytotoxic T lymphocyte clones specific for a photoreactive peptide derivative. Labeling of the alpha-chain correlates with J alpha segment usage.

Using a direct binding assay based on photoaffinity labeling, we studied the interaction of T cell receptor (TCR) with a Kd-bound photoreactive peptide derivative on living cells. The Kd-restricted Plasmodium berghei circumsporozoite (PbCS) peptide 253-260 (YIPSAEKI) was reacted NH2-terminally with biotin and at the TCR contact residue Lys259 with photoreactive iodo, 4-azido salicylic acid (IASA) to make biotin-YIPSAEK(IASA)I. Cytotoxic T lymphocyte (CTL) clones derived from mice immunized with this derivative recognized this conjugate, but not a related one lacking the IASA group nor the parental PbCS peptide. The clones were Kd restricted. Recognition experiments with variant conjugates, lacking substituents from IASA, revealed a diverse fine specificity pattern and indicated that this group interacted directly with the TCR. The TCR of four clones could be photoaffinity labeled by biotin-YIPSAEK(125IASA)I. This labeling was dependent on the conjugates binding to the Kd molecule and was selective for the TCR alpha (2 clones) or beta chain (1 clone), or was common for both chains (1 clone). TCR sequence analysis showed a preferential usage of J alpha TA28 containing alpha chains that were paired with V beta 1 expressing beta chains. The TCR that were photoaffinity labeled at the alpha chain expressed these J alpha and V beta segments. The tryptophan encoded by the J alpha TA28 segment is rarely found in other J alpha segments. Moreover, we show that the IASA group interacts preferentially with tryptophan in aqueous solution. We thus propose that for these CTL clones, labeling of the alpha chain occurs via the J alpha-encoded tryptophan residue.

A comparative study of T-cell receptor V beta usage in non-obese diabetic (NOD) and I-E transgenic NOD mice.

The non-obese diabetic (NOD) mouse is a model for the study of insulin-dependent diabetes mellitus (IDDM). Recently transgenic NOD mice have been derived (NOD-E) that express the major histocompatibility complex (MHC) class II I-E molecule. NOD-E do not become diabetic and show negligible pancreatic insulitis. The possibility pertained that NOD-E mice are protected from disease by a process of T-cell deletion or anergy. This paper describes our attempts to discover whether this was so, by comparing NOD and NOD-E mouse T-cell receptor V beta usage. Splenocytes and lymph node cells were therefore tested for their ability to proliferate in response to monoclonal anti-V beta antibodies. We were unable to show any consistent differences between NOD and NOD-E responses to the panel of antibodies used. Previously proposed V beta were shown to be unlikely candidates for deletion or anergy. T cells present at low frequency (V beta 5+) in both NOD and NOD-E mice were shown to be as capable of expansion in response to antigenic stimulation as were more frequently expressed V beta. Our data therefore do not support deletion or anergy as mechanisms which could account for the observed disease protection in NOD-E mice.

Mobilités numériques. De l'usage à l'expérience utilisateur (UX) du monde.

Résumé La mobilité ne signifie plus uniquement se mouvoir d'un point à un autre ; il s'agit d'un concept lui-même en constante évolution, grâce au progrès technique et à l'innovation sociale notamment. Aujourd'hui, la recherche de la vitesse n'est plus le seul enjeu au coeur de nos préoccupations. Elle a été remplacée par un retour au voyage enrichi par l'expérience et ce quelle que soit sa durée. Cet enrichissement s'est principalement fait par le truchement des technologies de l'information et de la communication et peut prendre plusieurs formes liées aux problématiques contemporaines de la ville et du territoire. Citons comme exemple la valorisation du temps de déplacement, grâce à un meilleur accès à l'information (travail, réseaux sociaux, etc.) et à la recherche d'une plus grande cohérence entre l'acte de se mouvoir et l'environnement proche ou lointain. Cette « recontextualisation » du mouvement nous interpelle dans notre rapport à l'espace et nous donne également des pistes pour repenser le métier d'urbaniste de la ville intelligente. Abstract Mobility issues do not only involve the act of moving nowadays. The concept itself evolves continuously thanks to technological and social innovations. The main stakes do not focus anymore on improving speed, but on enriching the experience of travelling, even in the case of short trips. One of the main factors that fosters this evolution is the progressive adoption of information and communication technologies that help to reshape the issues of contemporary cities. For example, the quality of travel time has improved thanks to the ubiquitous accessibility to information, and by offering a better coherence between the trip and the immediate social environment. The "recontextualisation" of everyday activities (working, interacting, etc.) challenges the relationship individuals have with space and offers many clues in regard to the required skills that urban planners and designers of the smart city should possess.

Analysis of patient physical restraints usage in a Swiss emergency service

Introduction: Emergency services (ES) are often faced with agitated,confused or aggressive patients. Such situations may require physicalrestraint. The prevalence of these measures is poorly documented,concerning 1 to 10% of patients admitted in the ES. The indications forrestraint, the context and the related complications are poorly studied.The emergency service and the security service of our hospital havedocumented physical restraint for several years, using specific protocolsintegrated into the medical records. The study evaluated the magnitudeof the problem, the patient characteristics, and degree of adherence tothe restraint protocol.Methods: Retrospective study of physical restraint used on adultpatients in the ES in 2009. The study included analysis of medical anddemographic characteristics, indications justifying restraint and qualityof restraint documentation. Patients were identified from computerizedES and security service records. The data were supplemented byexamination of patients' medical records.Results: In 2009, according to the security service, 390 patients (1%)were physically restrained in the ES. The ES computerized systemidentified only 196 patients. Most patients were male (62%). The medianage was 40 years (15-98 years; P90 = 80 years). 63 % of the situationsoccurred between 18h00 and 6h00, and most frequently on Saturday(19%). Substance or alcohol abuse was present in 48.7% of cases andacute psychiatric crisis was mentioned in 16.7%. In most cases,restraint was motivated by extreme agitation or auto / hetero-aggressiveviolence. Most patients (68 %) were restrained with upper limb andabdominal restraints. More than three anatomic restraints werenecessary in 52 % of the patients. Intervention of security guards wasrequired in 77% of the cases. 61 restraint protocols (31 %) were missingand 57% of the records were incomplete. In many cases, the protocolsdid not include the signature of the physician (22%) or of the nurse(43.8%). Medical records analysis did not allow reliable estimation ofthe number of restraint-induced complications.Conclusions: Physical restraint is most often motivated by majoragitation and/or secondary to substance abuse. Caregivers regularlycall security guards for help. Restraint documentation is often missing orincomplete, requiring major improvement in education and prescription.
