Early-blind individuals show impaired performance in wine odor categorization
2018
International audience; Blind individuals display superior sensory abilities in other modalities, yet results remain contradictory regarding their performance on olfactory tasks. Using complex ecological olfactory tasks, we evaluated the impact of blindness on olfactory performance. We tested 12 early-blind individuals (M = 49, SD = 13.09) and 12 sighted controls (M = 49, SD = 14.31) who were all blindfolded. Based solely on the wine odors, participants evaluated 24 pairs of wine and determined if both samples belonged to the same category (red wine, white wine, or rosé wine) or not (odor categorization), and if so, whether they were identical or not (odor differentiation). Then, they had t…
Impact of a reduction of plasmalogen levels on Muller cell metabolism
2016
Purpose : Retinopathy of Prematurity (ROP) is the leading cause of blindness in premature children resulting from abnormal vascular development. Previous studies have shown that omega-3 polyunsaturated fatty acids (PUFAs) can modulate physiologic and pathologic angiogenesis. Data from our laboratory suggest that plasmalogens, that are phospholipids that concentrate omega-3 PUFAs, are involved in the regulation of post-natal retinal vascular development through the action of a calcium-independent phospholipase A2 (iPLA2) (Saab et al PLoSONE 2014). In the retina, Müller cells are known to play crucial functions in retinal angiogenesis as well as to be rich in plasmalogens and to express phosp…
