Falls are frequent in the elderly and are responsible for an increased morbi-mortality. The elderly who has a tendency to fall is at higher risk of repeated hospitalisation and of institutionalisation. A link between cognitive and gait disorders is put forward by several recent studies. This paper is concerned with the various gait abnormalities encountered in the elderly, especially seriale gait, and the means to detect them. [less ▲]

The Zapara Indians in the Upper Amazon are on the verge of disappearing from the linguistic map. This is a fact. And yet, their emergence within the political landscape in Ecuador (but not yet in Peru), has provided them with a greater international visibility as an indigenous group. Most unusually, the accounts of dreams become one of the key elements of new forms of identity practices and identification processes – as those narrated here by two Zapara political leaders will attest. In search of their material and immaterial heritage, these leaders make use of the realm of dreams, using occurred dreams to orient their choices in the reconstruction of a collective memory. The dream, as a tool for engaging in a regredient process or in the return into the past, provides the historical elements that the Indians will then re-inject into their present in order to construct new “traditions”. In this dissertation, I will be describing the mechanisms, the learning of, and the local theories concerning the experience of dreams. In order to be understood, the dream must first circulate, and must have an issuer as a point of departure. Dreaming is also the means for a privileged relationship between human and non- human beings. Throughout this thesis, various systems of memory will be examined based upon empirical data revealing of the dreamt experience, but also of daily life, such as new teaching methods, or the creation of artefacts, produced both by ancestors or contemporaries. These accounts will help us to understand this new process of “Zaparaisation”, which depends as much on a process of ethno-archiving than on ethno-museography, and which awakens the immaterial.

Le secteur Open Source connaît une profonde mutation: à côté de l’idéologie libertaire prônée par ses défenseurs, il migre vers une "économie de marché" au sein de laquelle les acteurs développent désormais de réelles stratégies commerciales. A partir d’une étude exploratoire, basée sur l’analyse de six cas d’entreprises, notre recherche met en évidence les modèles d'affaires privilégiés par ces sociétés pour positionner leur offre de produits/services et générer un retour lucratif à leurs activités. Synthétisés au travers de trois approches distinctes – les logiques de la complexification, du système clos et de l’intermédiation –, ces modèles économiques reflètent des positionnements foncièrement différents par rapport à la philosophie Open Source et soulignent les ressources (au sens de Barney, 1991) que les entreprises mobilisent pour créer un lien de dépendance envers leur clientèle et se forger un avantage concurrentiel durable.

Introduction. -The goal of this study was to check if exercise raises oxidative stress markers in overweight teenagers (n = 29) compared to non obese (n = 17) ones. Synthesis. -Blood markers of insulin resistance, inflammation and oxidative stress were measured at rest and/or after a maximal exercise. At rest, the overweight teenagers exhibited an insulin resistance, an inflammation and an oxidative stress. After exercise, plasmatic myeloperoxidase and lipid hydroperoxides were increased only in overweight teenagers. However, the differences between groups disappeared when the values were reported to VO2 Pie suggesting that exercise intensity consitutes the major oxidative stress factor. Conclusions. -The relations between rest insulin resistance, inflammation and post-exercise oxidative stress indicate that those parameters contribute in post-exercise oxidative stress.

Northern elephant seals, Mirounga angustirostris, are exceptional mammals: females fast entirely during nursing while their pups may quadruple in weight over the 25-day suckling period. Females thus lose approximately a third of body mass and produce energy-rich milk with a high fat content. Stable carbon and nitrogen isotope ratios (d13C and d15N used as diet markers) and total mercury concentrations (Hg) were measured in tissues (blood cells, serum, full blood, milk and blubber) from 20 mother-pup pairs on days 4 and 21 of lactation. A systematic difference was observed between isotopic values in blood cells and serum of the mothers, linked to diet and distinct biochemical composition between blood components. d13C differed between inner and outer blubber layers and were similar between inner blubber and milk. High Hg concentrations (up to 350 ng.g-1ww at the beginning of lactation) were found in the blood of mother elephant seals linked to their high d15N values in blood cells. Hg transfer through placenta and milk was observed between mothers and pups. A significant increase of blood Hg concentration in mothers (+285 ng.g-1ww) and a decrease in pups (-93 ng.g-1ww) were observed between days 4 and 21 of lactation. Both processes were explained by a remobilization of proteins and lipids during fasting and milk production in mothers and by a dilution of Hg in pups due to their high mass increase during this period. This study confirms that lactation modifies stable nitrogen isotope ratios in tissues, as well as mercury levels in blood from mothers and pups, and highlights the existence of a transplacental and transmammary transfer of mercury in northern elephant seals. Therefore, physiological processes and body condition should be considered carefully when interpreting stable isotope ratios and Hg concentrations in the framework of biomonitoring. [less ▲]

The diachronic analysis of air photos and Corona satellite images shows that the erosion of the sandy coast of Tangier bay occurred at variable speeds between 1972 and 1997. The period between 1972-1981 shows generalized erosion with a rate of 4 m/year. The period of 1981-1997 registers a restoring of the average trend with the formation of three sectors, the first one in erosion with an average rate of 1,5 m/year, the second sector is stable and the third in accretion. Because of its remoteness from the production zones, the sandy beach evolves in a closed system. In fact, on the one hand, the construction of the harbour jetty intercepted the longshore drift generated by the west swell and, on the other hand, the development of the western hillside immobilized the sandy materials that do not contribute anymore to the current solid contribution. Finally, the longshore drift which redistributes the pebbles brought by the oued Halou is broken by the construction of a defence system. The fluvial discharges are henceforth immobilized between the breakwater and the eastern groyne and do not contribute to the sedimentary dynamics. This situation aggravates the impoverishment of the involved sedimentary stock. At present, the erosion that drew sediments of the beach from the most easterly beach to accrete that western portion can’t find more materials because of the erosion and of the quasitotal occupation of the beach. In fact, the western beach not nourished by sediments, will see its vulnerability increase gradually. The repairing of the beach further to successive storms is more difficult. This reality is already felt in 2006. On the other hand, a portion of the clayey coastal cliff of Tangier bay, considered as stable, sustains significant erosion. The mean rate of cliff retreat, recorded between 1981 and 1997, is estimated at 1,5m/year. The reconstructionof the natural coastal system and the monitoring of the successive developments in the bay show that the anthropization of the coast has unbalanced the system in an irreversible way.

Peripherin is an intermediate filament protein that is expressed in peripheral and enteric neurons. In the cochlear nervous system, peripherin expression has been extensively used as a differentiation marker by preferentially labeling the type II neuronal population at adulthood, but yet without knowing its function. Since the expression of peripherin has been associated in time with the process of axonal extension and during regeneration of nerve fibers in other systems, it was of interest to determine whether peripherin expression in cochlear neurons was a static phenotypic trait or rather prone to modifications following nerve injury. In the present study, we first compared the expression pattern of peripherin and beta III-tubulin from late embryonic stages to the adult in rat cochlea. The staining for both proteins was seen before birth within all cochlear neurons. By birth, and for 2 or 3 days, peripherin expression was gradually restricted to the type II neuronal population and their projections. In contrast, from postnatal day (P) 10 onwards, while the expression of beta III-tubulin was still found in projections of all cochlear neurons, only the type I population had beta III-tubulin immunoreactivity in their cell bodies. We next investigated the expression of peripherin in axotomized cochlear neurons using an organotypic explant model. Peripherin expression was surprisingly re-expressed in a vast majority of neurons after axotomy. In parallel, the expression and localization of beta III-tubulin and peripherin in dissociated cultures of cochlear neurons were studied. Both proteins were distributed along the entire neuronal length but exhibited complementary distribution, especially within the projections. Moreover, peripherin immunoreactivity was still abundant in the growth cone, whereas that of beta III-tubulin was decreasing at this compartment. Our findings are consistent with a model in which peripherin plays an important structural role in cochlear neurons and their projections during both development and regenerative processes and which is compatible with the assumption that frequently developmentally regulated factors are reactivated during neuronal regeneration.
