Comtesse puis duchesse d’Angoulême, Louise de Savoie (1476-1531) est l’une des personnalités les plus influentes de la première Modernité européenne. Elle n’est pas seulement la mère de deux enfants illustres, Marguerite, future reine de Navarre, et François, futur François Ier, elle est aussi la sœur de Philibert II le Beau, duc de Savoie. Une fois son fils monté sur le trône de France, Louise domine le Conseil et assure, à deux reprises, la régence du royaume. Son action concerne encore les arts et les lettres : amatrice d’objets d’art et bibliophile avertie, elle demande à Léonard de Vinci d’imaginer une ville et un palais neuf à Romorantin, participant de la sorte à la diffusion en France des idées et des formes venues d’Italie. Curieusement, alors que son influence fut considérable, Louise de Savoie n’a pas fait l’objet d’une monographie récente (un ouvrage collectif à son propos paraîtra toutefois en 2015). Son emblématique n’a plus été analysé depuis les travaux d’Anne-Marie Lecocq (1987), qui s’était essentiellement concentrée sur les signes présents dans les livres qu’elle commanda pour soutenir l’éducation de ses enfants. À l’occasion de cette communication – prolongeant ainsi une recherche entreprise avec Pierre-Gilles Girault – nous voudrions revenir sur le discours héraldique de Louise de Savoie, en explicitant l’une de ses devises favorites, la cordelière. Pour la mère de François Ier, la corde à plusieurs nœuds revêt plusieurs significations. D’abord, puisqu’elle se compose de nœuds de Savoie, un emblème largement diffusé au début du XVIe siècle, notamment sous l’influence de Philibert II le Beau et Marguerite d’Autriche, elle souligne l’appartenance de la dame à la maison de Savoie. Ensuite, et ce de façon inédite au sein de la maison de Savoie, la cordelière de Louise associe nœuds de Savoie et cordon franciscain, une référence que nous proposons d’expliquer non pas uniquement, comme on le fait traditionnellement, par les liens prétenduement étroits qui reliaient la mère de François Ier avec l’ordre des Franciscains. Pour Louise, il s’agit sans doute aussi de se situer dans la lignée d’Anne de Bretagne, à laquelle la cordelière est indéniablement liée. [less ▲]

Promoting affiliation between scientists is relatively easy, but creating larger organisational structures is more difficult, due to traditions of scientific independance, difficulties of sharing implicit knowledge, and formal organisational barrers. Hence there is a need to research possibilities given by Communities of practice.

Au cœur de l'espace de la cour, le confesseur du Prince présente un profil singulier. La relation qu'il entretient avec son pénitent est unique : tenu à l'obéissance envers le souverain ou son représentant pour les aspects temporels, ce religieux a la faculté unique d'examiner, de conseiller et de juger la spiritualité du premier personnage de l'État. Attaché à la personne du Prince, les relations de cet ecclésiastique avec les autres courtisans ne peuvent être appréhendées au moyen d'une grille de lecture hiérarchisant les rapports sociaux : échappant à l'organisation laïque – mais pas protocolaire – de la cour et ne dépendant pas directement de la Chapelle royale, le confesseur bénéficie d'une autonomie relative. En outre, son pouvoir politique, en partie officiel grâce aux dignités et charges dont ce religieux est pourvu, est avant tout perçu comme une magistrature d'influence à la portée difficilement mesurable. Enfin, les obligations matérielles liées à l'appartenance de ce prélat à un ordre religieux achèvent de distinguer cet ecclésiastique des autres serviteurs princiers. Cette communication visera à distinguer les particularités de la charge de confesseur princier au sein de la société de cour. L'étude portera particulièrement sur la cour de Bruxelles durant la première moitié du xviie siècle. [less ▲]

We revisit the limit on very light axion-like particles (ALPs) from the absence of gamma rays coincidental with the neutrino burst from SN1987A. We use updated supernova simulations, modern models for the magnetic field inside the Galaxy, and a Primakoff cross section which takes into account proton-degeneracy and mass-reduction effects. We finally give an updated exclusion plot for the electromagnetic coupling of sub-eV ALPs, comparing our new bound with other limits as well as with future ALP searches. [less ▲]

This paper develops a probabilistic approach for power system reliability management in real-time operation where risk is a product of i) the potential occurrence of contingencies, ii) the possible failure of corrective (i.e., post-contingency) control and, iii) the socio-economic impact of service interruptions to end-users. Stressing the spatiotemporal variability of these factors, we argue for reliability criteria assuring a high enough probability of avoiding service interruptions of severe socio-economic impact by dynamically identifying events of nonnegligible implied risk. We formalise the corresponding decision making problem as a chance-constrained two-stage stochastic programming problem, and study its main features on the single area IEEE RTS-96 system. We also discuss how to leverage this proposal for the construction of a globally coherent reliability management framework for long-term system development, midterm asset management, and short-term operation planning.

La crise généralisée qui, depuis quelques années, a affaibli les économies de nombre d’états, a eu des conséquences sur la typologie des migrations internationales : les trajectoires, les projets, les destinations, les départs se sont modifiés en fonction de nouveaux facteurs auxquels les individus et les groupes étaient confrontés . A côté de ces macro-dynamiques globales, la crise a également engendré des changements dans la vie quotidienne des migrants lorsqu’ils étaient déjà partis et qu’ils s’étaient déjà installés ailleurs. Dans ce cadre, ma contribution vise à analyser les pratiques d’approvisionnement alimentaire d’un groupe de migrantes marocaines en Italie mettant en place des stratégies pour faire face aux conséquences concrètes de la crise économique (notamment la diminution de leur pouvoir d’achat en conséquence de leur précarité professionnelle). Au travers de plusieurs déplacements dans la ville où elles habitaient et de la mobilisation des réseaux familiaux alimentant des circuits informels d’échange de biens, ces femmes satisfaisaient leurs différentes exigences – parmi lesquelles le désir de performer des préparations propres à leur mémoire incorporée – tout en répondant aux contraintes économiques déterminées par la crise. Je vais ainsi démontrer qu’en dépit des difficultés rencontrées, ces femmes arrivaient à exercer une agency dans le nouvel espace vécu et à se positionner de façon active au travers de leurs choix et conduites quotidiennes.

Background subtraction is usually based on low-level or hand-crafted features such as raw color components, gradients, or local binary patterns. As an improvement, we present a background subtraction algorithm based on spatial features learned with convolutional neural networks (ConvNets). Our algorithm uses a background model reduced to a single background image and a scene-specific training dataset to feed ConvNets that prove able to learn how to subtract the background from an input image patch. Experiments led on 2014 ChangeDetection.net dataset show that our ConvNet based algorithm at least reproduces the performance of state-of-the-art methods, and that it even outperforms them significantly when scene-specific knowledge is considered.

Probabilistic methods are emerging for operating electrical networks, driven by the integration of renewable generation. We present an algorithm that models a stochastic process as a Markov process using a multivariate Gaussian Mixture Model, as well as a model selection technique to search for the adequate Markov order and number of components. The main motivation is to sample future trajectories of these processes from their last available observations (i.e. measurements). An accurate model that can generate these synthetic trajectories is critical for applications such as security analysis or decision making based on lookahead models. The proposed approach is evaluated in a lookahead security analysis framework, i.e. by estimating the probability of future system states to respect operational constraints. The evaluation is performed using a 33-bus distribution test system, for power consumption and wind speed processes. Empirical results show that the GMM approach slightly outperforms an ARMA approach. [less ▲]

La communication veut aborder le thème du jeu et du sport du point de vue de l'emblème, genre littéraire et artistique en vogue en Europe à partir du XVIe siècle, qui lie le texte et l'image pour exprimer des concepts moraux. Le sport et le jeu mettant en scène dans un espace et un temps déterminés les situations les plus communes de l’existence, offrent au moraliste des riches arguments pour son discours : la victoire, le prix, l’injustice, l’honnêteté, la compétition, la passion, la sociabilité, les vices et les vertus. L’intensité symbolique des représentations de jeu et de sport accrue par le langage emblématique sera soulignée dans la communication afin de comprendre le message politique ou moral ancré à ces activités.

This paper focuses on simplified models of the Modular Multilevel Converter suitable for large-scale dynamic studies, in particular simulations under the phasor approximation. Compared to the existing literature, this paper does not a priori adopt the modeling approach followed for the original twolevel or three-level Voltage Source Converter. On the contrary, a model is derived following a physical analysis that preserves its average internal dynamic behavior. An equivalent control structure is proposed and various alternatives are highlighted. The proposed model with its controllers has been implemented in a phasor simulation software and its response has been validated against a detailed Electromagnetic Transient model. Finally, an illustrative example is presented with the application of the proposed model on a large grid consisting of AC areas interconnected with a multi-terminal DC grid. [less ▲]

Dans le cadre de nos recherches doctorales sur la typologie des papyrus documentaires grecs et latins à caractère médical, c’est cette lacune que l’on se propose de combler, d’une part en cataloguant, au moyen de la fiche Mertens-Pack³ du CEDOPAL, la trentaine de listes de produits pharmaceutiques provenant d’Égypte, écrites en grec sur papyrus et ostracon (IIIe s. av.

Syntactic analyses describe grouping operations that explain how words are combined to form utterances. The nature of these operations depends on the approach. In a constituency-based approach, grouping operations are ordered, or stratified, part-whole relations. In a dependency-based approach, grouping operations identify a governor (or head), i.e. they are directed hierarchical relations between words. It is possible to convert a constituency tree into a dependency tree by dereifying the nodes, by identifying the governor and by removing the stratification of the part-whole relations. Polygraphs combine the two types of information into a single structure and are therefore a more powerful formalism. By relaxing constraints, polygraphs also allow to underspecify both kinds of information. [less ▲]

Famous since the Odyssey (IV, 229-230) for its drugs, Egypt furnishes the Greek world with some medical substances already mentioned in the hippocratic treatises. Moreover, many Greek drug names have been loaned from the Egyptian language, such as ἄμ(μ)ι for cumin, κίκι for castor-oil, κόμμι for gum, κῦφι for a complex preparation used for fumigation in cult practices, νίτρον for sodium carbonate, στίμμι for galena, σῶρυ for ferrous sulfate, and σάμψ(ο)υχον, for marjoram, whose name means “herb (sem) of Soukhos", another name for the crocodile god Sobek. The trade of drugs, spices and colourants, used in pharmacology, cosmetology, painting, cultual and magical practices, embalming rites and nutrition always flourished in Egypt and has intensified in Hellenistic and Roman times. As a continuation of the research on remedies of Egyptian origin in Greco-Roman pharmacopoeia, this article provides a list of Egyptian ingredients used in Greek and Latin veterinary prescriptions. The use of these substances is compared with recomandations from human medicine. Their availability and costs are also studied. [less ▲]

This paper describes a novel methodology for conducting stable hybrid fire testing (HTF). During hybrid fire testing, only a part of the structure is tested in a furnace while the reminded structure is calculated separately, here by means of a predetermined matrix. Equilibrium and compatibility at the interface between the tested “physical substructure” and the “numerical substructure” is maintained throughout the test using a dedicated algorithm. The procedures developed so far are sensitive to the stiffness ratio between the physical and the numerical substructure and therefore they can be applied only in some cases. In fire field, the stiffness of the heated physical substructure may change dramatically and the resulting change in stiffness ratio can lead to instability during the test. To overcome this drawback, a methodology independent of the stiffness ratio has been developed, inspired from the Finite Element Tearing and Interconnecting (FETI) method, which has been originally developed for substructuring in numerical analyses. The novel methodology has been successfully applied to a hybrid fire test in a purely numerical environment, i.e. the physical substructure was also modelled numerically. It is shown that stability does not depend on the stiffness ratio and that equilibrium and compatibility can be consistently maintained at the interface during the fire. Finally, the ongoing experimental program aimed at employing and experimentally validating this methodology is described. [less ▲]

At Koksijde in Belgium a severe fire took place in an apartment building in 2015, resulting in the death of a young man and visible structural damage to four balconies. Following the fire, experts were mandated to assess the damage and the need for structural repair. They estimated that the balconies had to be refurbished but that there were no other structural elements affected, in particular the slab inside the apartment could be left in place with only a surface treatment and new plaster finishing. However, the floor slab in the apartment located above the fire apartment exhibited several visual indications that the fire could have had a structural impact, such as residual deformations and cracks in the tiles. This paper presents a methodology to infer the fire severity based on post-fire measurements and non-linear thermo-plastic numerical simulations. Finally, knowing the fire severity, its effect on the structure is evaluated and a reliability-based assessment is made of the residual load bearing capacity of the slab. [less ▲]

Fire fragility functions can be used to characterize the probabilistic vulnerability of buildings to fire in the context of urban resilience assessment. A methodology has been proposed to develop such functions for multi-story steel buildings. However, a large number of parameters with uncertainties play a role in the process of constructing the fragility functions. The goal of this research is to identify the critical parameters that most affect the global fire safety by investigating the sensitivity of the fragility functions to different input parameters. Sensitivity in parameters affecting the fire model, the heat transfer process and the thermo-mechanical response is examined. The effects of different design assumptions at the system level are also studied. The presented approach is useful for selecting the prevailing parameters in a fire reliability analysis and it provides important information for modeling tools that can be used to evaluate resilience for fire scenarios.

For designing concrete columns subjected to a standard fire exposure, the Eurocode permits the use of simplified or advanced calculation methods. For the designer, the question of the respective advantages of these two types of methods arises. Which situations demand the use of an advanced method? When does a simple method provide sufficient accuracy? In this paper, laboratory tests are recalculated using Finite Element Modeling (FEM) as an advanced and Extended Zone Model (EZM) as a simple method in order to investigate these questions. The recalculations indicate that the simple EZM is of sufficient accuracy for symmetric heated columns without restraints. In contrast, the mechanical behavior of columns heated on three sides demands an advanced method such as FEM to be properly described. [less ▲]

Fire brigades face a major threat when intervening in a building in fire: the possibility of structural collapse during the cooling phase of the fire, or soon thereafter. In the current approaches to structural fire engineering, the fire resistance rating (R) is generally the only measure taken into consideration to characterize the fire performance of structural elements, although this measure does not reflect the response in real fire conditions. In this work, a standard measure is proposed to characterize the ability of structural members to resist a natural fire including the decay phases. This measure yields information about the potential occurrence of delayed failure as a function of the duration of the fire before it started to decrease, whether by self-extinction or due to the action of the fire fighters. The paper presents the method to derive this new standard measure as well as results for different typologies of structural elements. Finally, the interpretation and practical consequences are discussed, in particular regarding the safety of fire fighters during an intervention. [less ▲]

This work provides a framework to evaluate the response of buildings in a community to fire following earthquake. As part of the framework, the paper discusses two methodologies: (1) how to develop fire fragility functions; (2) how the fire fragility functions can be used in conjunction with an original fire ignition model to estimate the potential losses in a community from fire following earthquake. The paper focuses in particular on the development of fire fragility functions for an entire building to measure the probability of reaching a damage state given a fire scenario. Next, the paper proposes an ignition model to evaluate the probability of fire ignition after an earthquake. The ignition model together with fragility functions measure the probability of damage from fire following earthquake given an earthquake scenario. [less ▲]

Hybrid testing is an appealing technique to observe the behavior of an element in an experimental test while taking into account the interaction with the rest of the structure which is modelled numerically. Being widely used in the seismic field, this technique has been recently proposed in the fire field. The purpose of this paper is to demonstrate that the loading control process may be unstable during the hybrid testing when using the methodology applied in former tests presented in the literature. The stability in the latter method depends on the stiffness ratio between the two substructures. For the purpose of discussion, a one degree-of-freedom elastic system is studied. To overcome the stability issues, a new method is presented, independent on the stiffness ratio. Finally, the hybrid testing of a 2D beam being part of a moment resisting frame is analyzed in a virtual environment (both parts being modeled numerically) using the “first generation method” and the new proposed method.

This paper addresses the problem of an aggregator controlling residential heat pumps to offer a direct control flexibility service. The service is defined by a 15 minute power modulation, upward or downward, followed by a payback of one hour and 15 minutes. The service modulation is relative to an optimized baseline that minimizes the energy costs. The potential amount of modulable power and the payback effect are computed by solving mixed integer linear problems. Within these problems, the building thermal behavior is modeled by an equivalent thermal network made of resistances and lumped capacitances whose parameters are identified from validated models. Simulations are performed on 100 freestanding houses. For an average 4.3 kW heat pump, results show a potential of 1.2 kW upward modulation with a payback of 600 Wh and 150 Wh of overconsumption. A downward modulation of 500 W per house can be achieved with a payback of 420 Wh and 120 Wh of overconsumption. [less ▲]

Le développement des activités sportives augmente la fréquence des lésions musculo-squelettiques de l’adolescent. Ces lésions dépendent non seulement du mécanisme mais également de l’âge du sportif et de sa maturation osseuse, particulièrement des noyaux d’ossification. Les aphophysoses, ostéochondroses ou ostéodystrophies se manifestent par une douleur au niveau de l’insertion tendineuse sur le noyau d’ossification secondaire en croissance. Elles sont souvent provoquées par des contraintes en traction-cisaillement chez des enfants sportifs entre 3 et 16 ans. L’excès pondéral constitue également un facteur de risque. La guérison spontanée s’observe généralement après trois à 12, voire 18 mois d’évolution. La maladie de Sever est l’ostéodystophie du pied la plus fréquente ; elle touche le noyau postérieur du calcanéum, qui apparaît entre sept et dix ans et qui fusionne à la fin de la puberté (16–18 ans) et sur lequel s’insèrent le tendon d’Achille et le court fléchisseur plantaire. Les contraintes en traction et compression (réception de saut) sont importantes à ce niveau surtout chez les sportifs de sept à 15 ans pratiquant diverses impulsions (basket-ball, volley-ball, saut en longueur. . . ). La talalgie se manifeste lors de la pratique sportive. La douleur est bilatérale dans 60% des cas. Il faut rechercher des troubles de statique plantaire (pieds creux) régulièrement associés à la maladie de Sever. Le bilan radiologique reste souvent décevant et peu spécifique. Le diagnostic différentiel doit s’établir avec une tendinopathie achilléenne, une fracture du calcaneus, un kyste osseux, un ostéome ostéoïde, une ostéomyélite ou une éventuelle enthésopathie (spondylarthropathie). La base du traitement est le repos sportif en phase algique, l’usage de la cryothérapie, le port de talonnettes amortissantes ou encore la prise temporaire d’AINS (ibuprofène). Au niveau du genou, l’apophysose de croissance la plus fréquente est la maladie d’Osgood-Schlatter qui est plus fréquente chez les adolescents pratiquant des sports de sauts. Au niveau du bassin tous les noyaux d’ossifications peuvent être atteints et même être le site de fractures-avulsions lors de contractions musculaires excessives ou brutales car le cartilage de croissance présente une faiblesse locale par rapport aux structures musculo-tendineuses. L’ostéochondrite disséquante correspond à un noyau osseux séparé du corps de l’os et recouvert de cartilage normal ; localisée à la partie supéromédiale du talus ou au niveau des condyles fémoraux. Elle est souvent asymptomatique, voire entraine une discrète limitation douloureuse de la mobilisation mais entraine une douleur à la palpation locale. Elle nécessite cependant un traitement adéquat. En cas de lésion peu ou pas évolutive, une surveillance radiologique (IRM / arthroscanner) est suffisante. Chez le très jeune adolescent une immobilisation plâtrée de six semaines permettrait la fusion du noyau (au niveau du dôme talien). L’arthroscopie sera justifiée en cas de séquestre osseux afin de l’extraire, et ce, avec de bons résultats postopératoires. L’ostéosynthèse d’un noyau volumineux peut être également indiquée, les résultats restant plus aléatoires. En conclusion, la pathologie traumatique ou microtraumatique de l’adolescent sportif n’est pas rare et ne doit jamais être négligée. Toute douleur exige une exploration radiologique comparative afin de poser un diagnostic précis et d’entreprendre un traitement adéquat, le plus souvent conservateur. [less ▲]

In order to effectively extract synthetic information from large spatial data sets, Spatial OnLine Analytical Processing (SOLAP) combines Geographic Information Systems (GIS) with Business Intelligence (BI) to query data warehouses through interactive vector maps. On the other hand, crime strategical analysis is usually based on raster maps computed by Kernel Density Estimation (KDE), then independent of any artificial boundary. This paper introduces an alternative vision of SOLAP which uses the raster model (instead of the vector one) in order to integrate crime data fields computed by KDE. It allows a continuous visualization of spatial data which, until now, has not been compatible with other SOLAP tools. The original geo-model is validated by a prototype adapted to the police needs.

Recently, researches have been conducted to discover and assess the usage of MPLS tunnels. Indeed, recent developments in the ICMP protocol make certain categories of MPLS tunnels transparent to traceroute probing. Additional techniques have been proposed to reveal the presence of MPLS tunnels when they do not explicitly appear in traceroute. It has been shown that MPLS is a very well deployed technology whose usage (i.e., Traffic Engineering, load balancing, etc.) varies in time and according to ASes. However, the MPLS structure on the Internet architecture has not been studied yet. In this paper, we follow this path by providing two contributions to the state of the art: (i) we evaluate the biases involved on MPLS tunnel detection when they are not directly revealed through traceroute. (ii), we provide some properties and architectural details related with MPLS deployment on router topology based on a k-core decomposition. [less ▲]

The biochip is plugged in the readout device without the use of an index matching fluid.

In this paper, we present an original method of dot-pattern generation dedicated to design optimization of large-size format ELBUs (Edge-Lit Light Guide Unit), where the number of dots greatly exceeds the maximum allowable number of optical objects supported by most common ray-tracing software. In the proposed method, in order to simplify the computational problem, an original optical system is replaced by an equivalent one. Accordingly, the original dot pattern is splitted into multiple small sections. Then, these sections are replaced by equivalent cells with continuous diffusing film. After that, we adjust the TIS (Total Integrated Scatter) two-dimensional distribution over the grid of equivalent cells, using an iterative optimization procedure. Finally, the obtained optimal TIS distribution is converted into the dot size distribution by applying an appropriate conversion rule. An original semi-empirical equation dedicated to rectangular large-size LGPs (Light Guide Plate) is proposed for the initial guess of the TIS distribution. It allows significantly reducing the time needed to dot pattern optimization. [less ▲]

Since the early 2000's, the Internet topology has been an attractive and important research topic, either for developing data collection mechanisms, and for analyzing and modeling the network. Beside traditional aspects of the Internet topology (i.e., IP interface, router, and AS levels), recent researches focused on intermediate promising visions of the topology, namely Point-of-Presence (PoP) and subnets (i.e., a set of devices that are located on the same connection medium and that can communicate directly with each other at the link layer). This paper focuses on network subnet discovery by proposing a new tool called treenet. One of the key aspects of treenet is that it builds a tree representing the way subnets are located with respect to each other. This tree allows treenet to obtain additional information on the network, leading to better analysis of the collected data. In this paper, we demonstrate the potential of treenet through the evaluation of its key algorithmic steps and the study of measurements collected from the PlanetLab testbed. [less ▲]

From continuous, the sediment transport becomes increasingly intermittent, with long periods of deficit in the sediment supply and short periods characterized by large supplies. Understanding how these intermittencies in the sediment supply affect the delta morphodynamics is of paramount importance for predicting the possible evolution and functioning of deltas. Deltas can reasonably be idealised as a reservoir, with an inlet channel representing the river and the sud- den enlargement of the reservoir representing the water body at rest. Using such an ideal configuration enables the assessment of the influence of individual geometric and hydraulic parameters on the depositional patterns responsible for the morphodynamic evolution of the delta. Recent literature has shown that for very similar hydraulic boundary conditions, two very different types of flow fields may develop (“straight jet” vs. “meandering jet”), leading to totally different depositional patterns. In turn, these distinct depositional patterns affect the flow itself through a two-way coupling between the hydrodynamics and the morphodynamics of the deposits. These complex processes will be discussed in the proposed presentation, based on the results of over 160 experimental tests and corresponding numerical simulations. [less ▲]

The study explores 31 MOOCs in the field of business administration, equipped with a conceptual framework documenting 18 facets of assessment design. As a second step, the data collected on 3 MOOCs about assessment is submitted to university members in charge of external courses accreditation procedures in order to ascertain its possible influence on their decision to credit a MOOC or not. Main results indicate that, a) the typical profile of the assessment procedure for MOOCs in business administration is: QCM-based, automatic, continuous, individual, product-centred, standardized, b) secure ways (proctoring, test-centres) to warrant learners’ identity for the tests can already be found in some MOOCs of this field, and c) concerns of course accreditors bear first and foremost on these student authentication aspects.

Context: Hypoxic-Ischemic encephalopathy (HIE) remains a major cause of perinatal brain injury. The brain rapidly increases in size, shape and complexity during the second and third trimesters. A sentinel event in late pregnancy or the intrapartum period may have an acute profound effect on a previously neurologically intact fetus, leading to the development of (HIE). The nature of the deficits is dependent on the gestational age and severity of the insult, though it is seldom reported in preterm infants. Studies in animal models of HIE may provide important information for the development of treatment for this pathological condition. Estetrol (E4) is a recently described estrogen with four hydroxyl-groups that is synthesized exclusively during pregnancy by the human fetal liver. Objective: In this study, we evaluated E4’s neuroprotective and therapeutic potency in neonatal (in vivo) HIE model of the immature 7-day-old newborn rat. Methods: Rat pups body temperatures were examined along with their body and brain weights. Brains were studied at the level of the hippocampus and cortex. Intact cell counting and expressions of markers for neuronal early grey matter damage (microtubule-associated protein-2 (MAP-2)), neurogenesis (doublecortin (DCX)) and angiogenesis (vascular-endothelial growth factor (VEGF)) were evaluated by histo- and immunohistochemistry. The serum levels of two markers of brain damage (S100B and glial fibrillary acidic protein (GFAP)) were measured by ELISA. Results: Our results demonstrate that E4 has a significant neuroprotective and therapeutic effects. Estetrol decreases the early gray matter loss, and promotes neuro- and angiogenesis in vivo. Estetrol treatment has no effects on body weight, brain weight or body temperature. Conclusion: Taken together, E4 might become an important safe and physiological substance to treat neonatal HIE.

Ces dernières années, grâce au perfectionnement des techniques de réanimation, le nombre de patients survivant à leur lésion cérébrale a fortement augmenté. Tandis que certains se rétablissent rapidement, d’autres traversent différents états de conscience altérée (coma, état végétatif/non répondant ou état de conscience minimale) avant de récupérer ou non un état de conscience normal. Les patients en état de conscience altérée représentent un problème majeur tant au niveau diagnostique, pronostique, thérapeutique, qu’au niveau de leur prise en charge quotidienne. Diverses possibilités de traitements pharmacologiques et non pharmacologiques ont été étudiées. Les techniques des stimulations transcrâniennes à courant continu (tDCS) augmentent l’excitabilité corticale et le flux sanguin cérébral régional. La plasticité cérébrale s’en voit améliorée, ce qui module l’activité corticale et donc l’activité fonctionnelle des aires se trouvant sous l’anode. Une plasticité cérébrale est parfois encore possible, même au stade chronique. Un des problèmes majeurs de ces patients est la spasticité qui cause diverses complications (rétractions musculaires, subluxations et luxations articulaires, escarres, positions vicieuses) en plus du facteur algique. Ces complications sont d’autant plus importantes que ces patients sont voués à rester alités. La kinésithérapie permet de réduire les complications liées à la spasticité mais est parfois insuffisante et la prise d’antispastiques est inévitable. La technique la plus couramment utilisée est l’étirement passif : son efficacité dans la réduction des phénomènes spastiques est clairement reconnue. Par ailleurs, des études ont montré l’intérêt de la mise en place d’une attèle souple au niveau du membre supérieur chez les patients spastiques. L’avantage de cette technique est sa simplicité d’utilisation. Cette attelle se base sur le principe de saturation du système proprioceptif cutané à l’aide d’un tissu élastique, ceci simultanément à un rééquilibrage des antagonistes. De nombreuses pistes restent encore à explorer pour une prise en charge optimale des patients cérébrolésés. [less ▲]
