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…
Plasma omega 3 polyunsaturated fatty acids and macular pigment optical density in subjects at high risk for age-related macular degeneration: the Lim…
2016
This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.; Purpose: In numerous epidemiological studies, omega 3 polyunsaturated fatty acids (PUFAs) have been associated with a decreased risk of age-related macular degeneration (AMD). Beyond their structural, functional and neuroprotective roles, omega 3 PUFAs may favor the retinal accumulation of lutein and zeaxanthin and thus increase macular pigment optical density (MPOD). We examined the associations of MPOD with plasma omega 3 PUFAs in subjects with at least one parent affected by neovascular AMD. Methods: The Limpia study is a double-blind, placebo controlled, prospective randomize…
Omega-3 Extraction from Anchovy Fillet Leftovers with Limonene: Chemical, Economic, and Technical Aspects
2019
International audience; We investigate selected chemical, technical, and economic aspects of the production of fish oil rich in polyunsaturated omega-3 fatty acids from anchovy filleting leftovers using d-limonene as the extraction solvent at ambient temperature and pressure. Entirely derived from the orange peel prior to orange squeezing for juice production, the bio-based solvent is easily recovered, affording a circular economy process with significant potential for practical applications.
