Graph Theoretical Framework of Brain Networks in Multiple Sclerosis: A Review of Concepts.
2019
Abstract Network science provides powerful access to essential organizational principles of the human brain. It has been applied in combination with graph theory to characterize brain connectivity patterns. In multiple sclerosis (MS), analysis of the brain networks derived from either structural or functional imaging provides new insights into pathological processes within the gray and white matter. Beyond focal lesions and diffuse tissue damage, network connectivity patterns could be important for closely tracking and predicting the disease course. In this review, we describe concepts of graph theory, highlight novel issues of tissue reorganization in acute and chronic neuroinflammation an…
Resting-State Functional Connectome in Patients with Brain Tumors Before and After Surgical Resection
2020
Purpose: High-grade glioma surgery has evolved around the principal belief that a safe maximal tumor resection improves symptoms, quality of life, and survival. Mapping brain function has been recently improved by resting-state functional magnetic resonance imaging (rest-fMRI), a novel imaging technique that explores networks connectivity at “rest.” Methods: This prospective study analyzed 10 patients with high-grade glioma in whom rest-fMRI connectivity was assessed both in single-subject and in group analysis before and after surgery. Seed-based functional connectivity analysis was performed with CONN toolbox. Network identification focused on 8 major functional connectivity networks. A v…
ESTRATEGIAS Y ESTILOS DE AFRONTAMIENTO PARENTAL EN FAMILIAS CON NIÑOS CON TRASTORNO DE ESPECTRO AUTISTA (TEA) CON O SIN TRASTORNO POR DÉFICIT DE ATEN…
2015
La crianza de un hijo con Trastorno del Espectro Autista (TEA) ocasiona un fuerte impacto sobre la dinámica familiar. Cuando este trastorno se presenta con otro comórbido, como el Trastorno por Déficit de Atención con Hiperactividad (TDAH), las repercusiones sobre el bienestar psicológico de los padres pueden verse considerablemente aumentadas. Conocer qué estilos y estrategias de afrontamiento se emplean con mayor frecuencia podría contribuir a diseñar intervenciones con las familias, que pudieran repercutir positivamente en la manifestación de la sintomatología autista. El objetivo de este estudio consiste en profundizar en los estilos y estrategias de afrontamiento más frecuentes de esta…
The Environmental Issue in Sicily
2014
In Italy, despite the number of protected natural areas and the abundance of scientific research upon the landscape, the level of control of human pressure on the environmental system is still seriously inadequate. Among the main factors is the disconnection between urban/regional and sectorial planning, in the frame of the detachment of the nature conservation policies from the landscape and territorial policies, which is the focus of the present research. The regional situation is rendered even more serious by the lack of an up-to-date planning law (the Sicilian planning law was passed in 1978), the poor diffusion of territorial and vast area planning (the Regional Master Plan has never b…
Off the grid. Touristische Idyllen der Entnetzung
2021
Abstract The article examines the relation of tourism and idyll in regard to the mediation of the tourist experience. Digital detox tourism and off grid tourism are two examples of contemporary tourism – including their respective practices and ways of promotion – that associate certain cultural stereotypes with the idyll. While digital detox tourism promises independence from the digital world, off grid tourism detaches the tourist from infrastructure and supplies. Paradoxically, the advertising of these types of ‘disconnection’ makes use of the same linked infrastructures that tourists are bound to leave behind. Thus, this article reveals the ways in which digital detox tourism and off gr…
Functional reorganization of the attentional networks in low-grade glioma patients: a longitudinal study.
2015
International audience; Right brain damage often provokes deficits of visuospatial attention. Although the spatial attention networks have been widely investigated in stroke patients as well as in the healthy brain, little is known about the impact of slow growing lesions in the right hemisphere. We here present a longitudinal study of 20 patients who have been undergoing awake brain surgery with per-operative line bisection testing. Our aim was to investigate the impact of tumour presence and of tumour resection on the functional (re)organization of the attention networks. We assessed patients' performance on lateralized target detection, visual exploration and line bisection before surger…
The left occipitotemporal system in reading: disruption of focal fMRI connectivity to left inferior frontal and inferior parietal language areas in c…
2011
Developmental dyslexia is a severe reading disorder, which is characterized by dysfluent reading and impaired automaticity of visual word processing. Adults with dyslexia show functional deficits in several brain regions including the so-called "Visual Word Form Area" (VWFA), which is implicated in visual word processing and located within the larger left occipitotemporal VWF-System. The present study examines functional connections of the left occipitotemporal VWF-System with other major language areas in children with dyslexia. Functional connectivity MRI was used to assess connectivity of the VWF-System in 18 children with dyslexia and 24 age-matched controls (age 9.7-12.5 years) using f…
Overcoming the “lost before translation” problem: An exploratory study
2019
This paper draws on Stokes’ (1997) framework to position the disconnection between theory and practice as a knowledge production problem. In this sense, we argue that a better understanding of different academic profiles is extremely important to focus efforts on those academics that may overcome the ‘lost before translation’ problem. Our data, that come from a survey of researchers affiliated to the Spanish National Research Council (CSIC), provide a good opportunity to explore the factors that might increase or impede the likelihood that researchers engage in research that reconciles the quest for fundamental understanding with the consideration of use (Pasteur’s profile), rather than in …
Cumulative risks for health of adolescent girls and boys: Disconnection from both family and school contexts
2008
International audience; In this presentation, concerning adolescents’ health, we want to show the interest to consider both gender and quality of contextual transactions. For this, the presented study aims at examining the links between contextual disconnections, from family and school, and the health of girls and boys, according to the extent and scope of the contextual disconnection and the health outcomes under consideration. Middle school adolescents – 521 girls and 466 boys – participated in this research. Three health measures were used: externalized disorders, internalized disorders, and consumptions. Four groups were constituted: No disconnection, Family or School disconnection (sin…
Bio-ecological approach applied to adolescents’ health: Girls and boys in situations of contextual disconnection
2011
International audience; In this study, we base on Bronfenbrenner’s bioecological model and propose to examine health behaviours of adolescents – girls and boys – in light of the Person-Context transactions. More precisely, we consider as a special issue the relations between health and degraded contextual Person-Family and/or Person-School transactions. One thousand and six French middle-school (8th grade) adolescents, 479 boys and 527 girls, took part in this study. They were categorized into four groups: Family disconnected adolescents, School disconnected adolescents, Double disconnected adolescents (that is, adolescents who are disconnected to both contexts), and Not disconnected adoles…
