    Une Intervention Psycho-oncologique d'Inspiration Psychodynamique

    Get PDF
    Introduction. La détresse psychique touche entre 30 et 50% des patients atteints de cancer (1-5). Les troubles psychiatriques les plus fréquemment observés sont les états dépressifs et les troubles anxieux et d'adaptation (1). En ce qui concerne les approches psychodynamiques auprès de patients atteints de cancer, il manque des études évaluant l'effet de ces thérapies. L'objectif de ce travail de master est d'investiguer une intervention psychothérapeutique d'inspiration psychodynamique effectuée auprès de patients nouvellement diagnostiqués de cancer. Méthode. Basée sur la lecture de 20 rapports, une grille de lecture des thématiques abordées dans les interventions a été élaborée puis discutée en deux focus groups entre trois chercheurs. Pour l'analyse semi-quantitative, deux de ces chercheurs ont appliqué la grille d'analyse à tous les rapports (N=135) et ont ensuite confronté et discuté leurs classifications jusqu'à l'obtention d'un consensus. Résultats. Une liste de vingt thématiques classées dans deux catégories a été élaborée: 1) témoignage/demande de soutien et 2) introspection avec les sous-catégories 2.1) changement de fonctionnement psychologique et 2.2) modification du positionnement relationnel. La moitié (50,4%) des patients ont consulté pour témoigner ou demander un soutien, 27,4% pour un changement de fonctionnement psychologique et 9,6% pour une modification du positionnement relationnel; 12,6% des patients n'ont pas pu être classifiés. En général, les patients consultant pour témoigner ou demander un soutien sont légèrement plus âgés et présentent un stade de maladie plus avancé, et consultent en moyenne durant 4 à 5 séances. Les patients qui visent un changement de fonctionnement psychologique suivent une tendance inverse et consultent en moyenne durant 11 à 12 séances; ceux qui désirent une modification de leur positionnement relationel sont également légèrement plus jeunes, avec un stade de maladie moins avancé, mais leur nombre de séances effectuées est très variable. Lorsque les patients effectuent un travail sur soi ou sur leurs relations, les sujets abordés ne sont que rarement centrés sur le cancer. Par contre, chez des patients qui consultent pour témoigner ou être soutenus, les angoisses liées au cancer sont plus souvent au coeur de l'intervention thérapeutique. Discussion. Les rapports de psychothérapie de patients atteints de cancer rédigés dans le cadre d'une étude sont sujets à la subjectivité des thérapeutes et à leurs interprétations quant au processus thérapeutique. Et il en va de même pour l'analyse que les chercheurs en font. Néanmoins, les résultats montrent qu'une grande variété de thématiques sont abordées durant les thérapies et que "l'évènement cancer" n'est pas toujours au centre des entretiens; avec certains patients les thérapeutes entament un travail plus conséquent en ce qui concerne sa durée et son contenu; travail qui va au-delà de "l'évènementiel". Les patients des différentes catégories identifiées se distinguent clairement quant à leur désir d'approfondir un travail thérapeutique, quant aux objectifs qu'ils souhaitent atteindre et quant au type d'intervention psychothérapeutique dont ils ont besoin. Conclusion. Les approches psychothérapeutiques pour les patients atteints de cancer demandent du thérapeute une grande souplesse, afin de s'adapter à la demande et aux capacités d'élaboration des patients. Une clarification rapide de ces deux paramètres dans les premières séances devrait faire partie intégrante de la prise en charge

    Voltage-controlled inversion of tunnel magnetoresistance in epitaxial Nickel/Graphene/MgO/Cobalt junctions

    Get PDF
    We report on the fabrication and characterization of vertical spin-valve structures using a thick epitaxial MgO barrier as spacer layer and a graphene-passivated Ni film as bottom ferromagnetic electrode. The devices show robust and scalable tunnel magnetoresistance, with several changes of sign upon varying the applied bias voltage. These findings are explained by a model of phonon-assisted transport mechanisms that relies on the peculiarity of the band structure and spin density of states at the hybrid graphene|Ni interface

    First evidence for postzygotic reproductive isolation between two populations of Eurasian perch (Perca fluviatilis L.) within Lake Constance

    <p>Abstract</p> <p>Background</p> <p>The evolution of reproductive traits, such as hybrid incompatibility (postzygotic isolation) and species recognition (prezygotic isolation), have shown their key role in speciation. Theoretical modeling has recently predicted that close linkage between genes controlling pre- and postzygotic reproductive isolation could accelerate the conditions for speciation. Postzygotic isolation could develop during the sympatric speciation process contributing to the divergence of populations. Using hybrid fitness as a measure of postzygotic reproductive isolation, we empirically studied population divergence in perch (<it>Perca fluviatilis </it>L.) from two genetically divergent populations within a lake.</p> <p>Results</p> <p>During spawning time of perch we artificially created parental offspring and F<sub>1 </sub>hybrids of the two populations and studied fertilization rate and hatching success under laboratory conditions. The combined fitness measure (product of fertilization rate and hatching success) of F<sub>1 </sub>hybrids was significantly reduced compared to offspring from within population crosses.</p> <p>Conclusion</p> <p>Our results suggest intrinsic genetic incompatibility between the two populations and indicate that population divergence between two populations of perch inhabiting the same lake may indeed be promoted by postzygotic isolation.</p

    (uk) Одним з найяскравіших прикладав інтертекстуального творення є роман М. Булгакова «Майстер та Маргарита». Ця стаття є спробою порівняльного аналізу твору російського письменника і казки Дж. Толкієна «Листок Ніггла», найповніше простежуються особливості деміургійного процесу. Дж. Толкієн у короткій казці оповідає долю генія, в алегоричній формі розкриває його (генія) здібності до створення та перетворення світу.(en) The article is devoted to the comparative analysis of J. Tolkien's and M. Bulgakov's creative conception that is mostly embodied in the works «Leaf by Niggle» and «Master and Margaret». The main character of the tale «Leaf by Niggle» resembles other J. Tolkien's heroes and the author himself. The tale is devoted to the fate of a genius, opens his abilities for creation and transformation o f the world

The definitive version was published in Behavioral Ecology and Sociobiology 59 (2006): 461-468, doi:10.1007/s00265-005-0070-3.Prior studies have shown that perch (Perca fluviatilis L.) of Lake Constance belong to two genetically different but sympatric populations, and that local aggregations of juveniles and adults contain closely related kin. In this study we analysed the genetic structure of pelagic perch larvae to investigate, if kin structured shoals already exist during early ontogenetic development or might be the result of homing to natal sites. Analysis of the gene frequencies at five microsatellite loci revealed that 3 out of 5 pelagic aggregations of larvae showed significant accumulation of kin. To investigate possible mechanisms of shoal formation, we tested if perch use olfactory cues to recognize their kin. Choice tests in a fluviarium showed preference for odours of unfamiliar kin versus unfamiliar non-kin. Additionally, we showed that perch could differentiate between the odours of the two sympatric populations and significantly preferred unfamiliar and unrelated conspecifics of their own over the foreign population. Our results present a behavioural mechanism that could lead to the observed formation of kin structured shoals in perch. We further discuss if the ability to discriminate between the own and the foreign population could result in assortative mating within populations and thus form the basis of “socially mediated speciation” in perch.Funding was provided by Deutsche Forschungsgemeinschaft within the collaborative research center SFB 454, Littoral of Lake Constance, the “Fonds der Chemischen Industrie”, University of Konstanz, and the “Konrad Adenauer-Stiftung”

    Spatio-temporal localization of selected pectic and arabinogalactan protein epitopes and the ultrastructural characteristics of explant cells that accompany the changes in the cell fate during somatic embryogenesis in Arabidopsis thaliana

    During somatic embryogenesis (SE), explant cells undergo changes in the direction of their differentiation, which lead to diverse cell phenotypes. Although the genetic bases of the SE have been extensively studied in Arabidopsis thaliana, little is known about the chemical characteristics of the wall of the explant cells, which undergo changes in the direction of differentiation. Thus, we examined the occurrence of selected pectic and AGP epitopes in explant cells that display different phenotypes during SE. Explants examinations have been supplemented with an analysis of the ultrastructure. The deposition of selected pectic and AGP epitopes in somatic embryos was determined. Compared to an explant at the initial stage, a/embryogenic/totipotent and meristematic/pluripotent cells were characterized by a decrease in the presence of AGP epitopes, b/the presence of AGP epitopes in differentiated cells was similar, and c/an increase of analyzed epitopes was detected in the callus cells. Totipotent cells could be distinguished from pluripotent cells by: 1/the presence of the LM2 epitope in the latest one, 2/the appearance of the JIM16 epitope in totipotent cells, and 3/the more abundant presence of the JIM7 epitope in the totipotent cells. The LM5 epitope characterized the wall of the cells that were localized within the mass of embryogenic domain. The JIM8, JIM13 and JIM16 AGP epitopes appeared to be the most specific for the callus cells. The results indicate a relationship between the developmental state of the explant cells and the chemical composition of the cell walls
