Substrate specificity overlap and interaction between Adrenoleukodystrophy protein (ALDP/ABCD1) and Adrenoleukodystrophy-related protein (ALDRP/ABCD2)
2011
X-linked adrenoleukodystrophy (X-ALD) is a neurodegenerative disorder caused by mutations in the ABCD1 gene, which encodes a peroxisomal member of the ATP-binding cassette (ABC) transporter subfamily D called ALDP. ALDP is supposed to function as a homodimer allowing the entry of CoA-esters of very-long chain fatty acids (VLCFA) into the peroxisome, the unique site of their β-oxidation. ALDP deficiency can be corrected by overexpression of ALDRP, its closest homolog. However, the exact nature of the substrates transported by ALDRP and its relationships with ALDP still remain unclear. To gain insight into the function of ALDRP, we used cell models allowing the induction in a dose-dependent m…
Effects of electrical stimulation pattern on quadriceps isometric force and fatigue in individuals with spinal cord injury
2015
Introduction Variable frequency trains (VFT) or train combinations have been suggested as useful strategies to offset the rapid fatigue induced by constant frequency trains (CFT) during electrical stimulation. However, most studies have been of short duration with limited functional application in those with spinal cord injury (SCI). We therefore tested force and fatigue in response to VFT, CFT, and combined patterns in strength training-like conditions (6-s contractions). Methods Ten SCI individuals underwent either CFT or VFT patterns until target torque was no longer produced and then switched immediately to the other pattern. Results Target torque was reached more times when VFT was use…
Anticipatory postural adjustments during joint action coordination
2019
International audience; There is a current claim that humans are able to effortlessly detect others’ hidden mental state by simply observing their movements and transforming the visual input into motor knowledge to predict behaviour. Using a classical paradigm quantifying motor predictions, we tested the role of vision feedback during a reach and load-lifting task performed either alone or with the help of a partner. Wrist flexor and extensor muscle activities were recorded on the supporting hand. Early muscle changes preventing limb instabilities when participants performed the task by themselves revealed the contribution of the visual input in postural anticipation. When the partner perfo…
Biocontrol of drosophila suzukii by two fatty acids
2020
International audience; Olfaction is a crucial sense for insects to detect food, seek partners or escape dangers. Volatile molecules are mainly perceived through insects' antenna. Odors bind to specific olfactory receptors located in sensilla. Olfactory sensory neurons then synapse on corresponding specific glomeruli of the antennal lobe, the primary olfaction center. This olfactory information is processed in higher centers to trigger a behavioral response. Understanding how odors can influence insect behavior is fundamental in order to protect cultures from pests. In this work, 2 volatile fatty acids are shown to modify significantly Drosophila suzukii courtship and copulation at increasi…
Socio-emotional Experience in Human Technology Interaction Design – A Fashion Framework Proposal
2021
Technology designers and developers can be understood as social experience (SE) mediators. In user experience (UX), notions of SE have served to identify and define the factors contributing to human-technology interaction (HTI). Three dominant perspectives have been promoted in UX discourse: 1) SE of brand, brand value and consumer culture; 2) technology design as mediator of human-to-human interactions; and 3) meaning generation through action and interaction between actors. Symbolic interactionalism understands meaning as occurring through dialogue, in the construction of the social self, promoting self-reflection as a social construction. This theorisation of social experience is valuabl…
Curiosités à la Colette, czyli o osobliwościach i niezwykłościach codzienności
2016
Twórczość Sidonie-Gabrielle Colette jawi się jako swoisty gabinet osobliwości. Owe niezwykłości to kurioza związane z tajemnicami natury, przedmiotami codziennego użytku, a także sferą doznań, które wpływają na poznawanie oraz smakowanie życia. W niniejszym artykule kurioza rozumiane są w kategoriach fascynacji, stanu emocjonalnego, wynikającego z odkrywania, podziwiania nowych rzeczy lub osób, a także rozkoszowania się różnorodnością doświadczeń i możliwości przekraczania tabu. Niezwykle interesujące wydaje się w tym aspekcie „pożądanie skarbów”, które implikuje specyficzne upojenie lub ekscytację rzeczywistością. Ukazanie odmienności świata pozwala przeżyć zachwyt - odczuwany wszystkimi z…
Dreams and Trauma Changes in the Manifest Dreams in Psychoanalytic Treatments - A Psychoanalytic Outcome Measure.
2021
Although psychoanalysts are interested in symptom reduction as an outcome, they are looking for instruments to measure sustaining changes in the unconscious mental functioning. In this article it is discussed that conceptually well-founded transformation of manifest dreams analyzed with precise empirical methods could be considered as a promising indicator for such therapeutic changes. We are summarizing a dream generation model by Moser and von Zeppelin which has integrated a large interdisciplinary knowledge base of contemporary dream and sleep research. Based on this model the authors have developed a valid and reliable coding system for analyzing manifest dreams, the Zurich Dream Proces…
Rheological Properties and Flavor Release
2010
International audience; Food texture may be of concern at different levels but is a main concern during food consumption. In fact, the way to handle food depends a lot on its texture: beyond interindividual differences, liquid products are swallowed more rapidly than solid products. e strength applied by teeth to bite food products and to transform the food bolus depends a lot on food stiffness. When food is eaten, it undergoes many modifications due to mastication, but also dilution through the addition of saliva, and variation in temperature. ese modifications result in great changes in food structure and texture, and thus involve significant changes in the partition of aroma compounds be…
¿Pueden los juegos mejorar la habilidad lectora?
2017
Investigaciones recientes han mostrado que las habilidades lectoras pueden ser moduladas mediante el entrenamiento en juegos/videojuegos. Dado que un déficit en atención visual puede ser causante de la dislexia, el entrenamiento en videojuegos puede mejorar la atención visual, lo cual puede ayudar al tratamiento de la dislexia. Pero también un juego de mesa como es el Scrabble puede mejorar las habilidades lectoras: los jugadores expertos de Scrabble tienen unas destrezas ortográfico-léxicas más eficientes que los no expertos. Trabajos futuros han de centrarse en examinar qué beneficios aporta el entrenamiento mediante juegos/videojuegos en la mejora del aprendizaje lector.
Detección temprana de la dislexia mediante el reconocimiento de voces
2015
Un aspecto clave para la intervención educativa específica es la detección temprana de niños con riesgo de dislexia. En este trabajo presentamos una sencilla tarea conductual de asociación de voces (modalidad auditiva) con avatares (modalidad visual), en la que las personas con dislexia muestran un rendimiento más bajo que las personas normo-lectoras. Dicho patrón de datos ocurre no solamente con lectores adultos, sino también con niños. Por tanto, esta tarea de integración multisensorial puede ser empleada como un marcador de la dislexia, en conjunto con otras tareas (v.g., conocimiento fonológico).
