Données textuelles, données expérimentales : quels apports pour une sémantique de la sensorialité ?
2019
International audience; Cette communication présente, explique et exemplifie le programme de recherche de l’équipe dijonnaise travaillant, au sein de l’EA 4182, à la mise en place d’un protocole éprouvé d’analyse discursive multi-niveaux des « discours du sensoriel », ce choix de dénomination reflétant l’orientation majeure de l’équipe. En effet, il ne s’agit pas ici de chercher dans la langue ce qui exprime le sensoriel, mais bel et bien de partir de réalités extra-linguistiques ayant une dimension sensorielle pour en récolter le matériau de mise en discours qui sera ensuite l’objet des études de cas. Une première partie met en évidence le caractère éminemment interdisciplinaire de l’objet…
Drumstick (
2019
The present work investigated the efficacy of Moringa flower (MF) extract to develop a functional chicken product. Three groups of cooked chicken nuggets—control (C), T1 (with 1% MF) and T2 (2% MF)—were elaborated and their physicochemical, nutritional, storage stability and sensory attributes were assessed during refrigerated storage at 4 °C up to 20 days. In addition, MF extracts were characterised in terms of chemical composition, total phenolic content and its components using high-performance liquid chromatography with a diode-array detector (HPLC-DAD), dietary fibre and antioxidant capacity. MF contained high protein (17.87 ± 0.28 dry matter), dietary fibre (36.14 ± 0.77 dry matter) a…
Caractérisation et prévention des conséquences d’un syndrome métabolique dans la rétine
2018
Metabolic syndrome (MetS) results from carbohydrate and lipid disorders that originate from misbalanced energy metabolism. MetS is a risk factor for type 2 diabetes that, in pathophysiological conditions, is characterized by vascular alterations, particularly in the retina, creating the diabetic retinopathy (DR). Despite it presents a barrier limiting the input of blood factors, the retina is under metabolic variations. The consequences of MetS in the retina have not been characterized. MetS would be responsible for the inflammation and microvascular alterations in the retina and could participate to the development of age-related macular degeneration (AMD). A diet rich in omega-3 long chai…
Maternal n-3 long chain polyunsaturated fatty acids increase n-3 fatty acids in brain glial cells and retina in the rat and improve rod sensitivity
2007
International audience; Purpose: To evaluate the efficacy of long chain n-3 polyunsaturated fatty acids (LC-PUFA) given to female rats during gestation and lactation on the incorporation of n-3 PUFA in the retina and brain glial cells of the newborn rat, and to evaluate the consequences on the electroretinographic (ERG) response. Methods: Sprague Dawley rats were fed during gestation and lactation with a 20%-lipid rich diet containing 0.75% of EPA and 0.55% of DHA. The fatty acid profile was analyzed in the eyeball and in brain glial cells of the litters sacrificed at birth. The retina and brain glial cell phospholipids were similarly analyzed in 14 day-old rats and in the mothers. Standard…
Effects of different lower-limb sensory stimulation strategies on postural regulation : A systematic review and meta-analysis
2017
Systematic reviews of balance control have tended to only focus on the effects of single lower-limb stimulation strategies, and a current limitation is the lack of comparison between different relevant stimulation strategies. The aim of this systematic review and meta-analysis was to examine evidence of effects of different lower-limb sensory stimulation strategies on postural regulation and stability. Moderate- to high- pooled effect sizes (Unbiased (Hedges’ g) standardized mean differences (SMD) = 0.31–0.66) were observed with the addition of noise in a Stochastic Resonance Stimulation Strategy (SRSS), in three populations (i.e., healthy young adults, older adults, and individuals with lo…
Type 1 macular telangiectasia
2018
L’identification à l’examen clinique de petites dilatations anévrismales et d’ectasies paracentrales fait évoquer le diagnostic de télangiectasies maculaires. Celles-ci sont le plus souvent secondaires à une pathologie, notamment au diabète, aux occlusions veineuses, aux vascularites, à un néovaisseau choroïdien de type 3, etc. Le contexte et le reste de l’examen identifieront généralement l’affection primitive. Les télangiectasies maculaires de type 1 (MacTel 1) sont idiopathiques sans cause retrouvée. Ce sont des affections rares, en grande majorité unilatérales, touchant préférentiellement l’homme d’âge moyen (1).
Retinal Detachments Following Successful Idiopathic Macular Holes Surgery
2009
Purpose: : To evaluate long term outcome of successfully operated idiopathic macular holes (IMH).Methods: : We conducted a comparative retrospective case series in two academic centers. IMH were operated with pars plana vitrectomy, intravitreal gas and internal limiting membrane peeling between 2002 and 2005. All these macular holes were analyzed with Stratus OCT before and after the surgery. We divided them into 4 groups: group 1: vitrectomy in pseudophakic eyes; group 2: vitrectomy and cataract extraction as a combined procedure; group 3: vitrectomy followed by cataract extraction; group 4: vitrectomy in pseudophakic eyes. We noted the anatomical and functional results and we studied seri…
Bilateral activations in operculo‐insular area show temporal dissociation after peripheral electrical stimulation in healthy adults
2018
Interhemispheric transfer is necessary for sensory integration and coordination of body sides. We studied how somatosensory input from one body side may reach both body sides. First, we investigated with 17 healthy adults in which uni‐ and bilateral brain areas were involved in consecutive stages of automatic sensory processing of non‐nociceptive peripheral stimulation. Somatosensory evoked fields (SEFs) to electrical stimulation were recorded with 306‐channel magnetoencephalography in two conditions. First, SEFs were registered following sensory radial nerve (RN) stimulation to dorsal surface of the right hand and second, following median nerve (MN) stimulation at the right wrist. Cortical…
Audiovisual processing of Chinese characters elicits suppression and congruency effects in MEG
2019
Learning to associate written letters/characters with speech sounds is crucial for reading acquisition. Most previous studies have focused on audiovisual integration in alphabetic languages. Less is known about logographic languages such as Chinese characters, which map onto mostly syllable-based morphemes in the spoken language. Here we investigated how long-term exposure to native language affects the underlying neural mechanisms of audiovisual integration in a logographic language using magnetoencephalography (MEG). MEG sensor and source data from 12 adult native Chinese speakers and a control group of 13 adult Finnish speakers were analyzed for audiovisual suppression (bimodal responses…
