Lutein and Brain Function

Foods, 2015
Lutein is one of the most prevalent carotenoids in nature and in the human diet. Together with zeaxanthin, it is highly concentrated as macular pigment in the foveal retina of primates, attenuating blue light exposure, providing protection from photo ...

Lipoxygenase in Wheat: Genetic Control and Impact on Stability of Lutein and Lutein Esters [PDF]

Foods, 2021
Preservation of lutein concentrations in wheat-based end-products during processing is important both for product quality and nutritional value. A key constituent involved in lutein degradation is endogenous lipoxygenase.

Lutein-Loaded, Biotin-Decorated Polymeric Nanoparticles Enhance Lutein Uptake in Retinal Cells

Pharmaceutics, 2020
Age related macular degeneration (AMD) is one of the leading causes of visual loss and is responsible for approximately 9% of global blindness. It is a progressive eye disorder seen in elderly people (>65 years) mainly affecting the macula.

Dietary Carotenoids and Cognitive Decline: A Longitudinal Study Among Chinese Middle-Aged and Older Adults. [PDF]

Health Care Sci
Higher intake of dietary carotenoids was associated with slower cognitive decline. The strongest protective association was observed for moderate carotenoid intake. Total carotenoid intake exhibited a non‐linear association with cognitive decline. ABSTRACT Background This study examined the association between dietary intakes of total and specific ...

Candidate gene study of macular response to supplemental lutein and zeaxanthin. [PDF]

, 2013
Supplementation with carotenoids is proposed to protect against age-related macular degeneration. There is, however, considerable variability in retinal macular pigment response, which may be due to underlying genetic variation. The purpose of this study

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

, 1992
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

Enhanced Productivity of a Lutein-Enriched Novel Acidophile Microalga Grown on Urea [PDF]

, 2010
Coccomyxa acidophila is an extremophile eukaryotic microalga isolated from the Tinto River mining area in Huelva, Spain. Coccomyxa acidophila accumulates relevant amounts of b-carotene and lutein, well-known carotenoids with many biotechnological ...

Dietary Intervention With Lutein, Docosahexaenoic Acid, and Choline During Early Development Improves Recognition Memory in Young Adult Females in an Experimental Model. [PDF]

Mol Nutr Food Res
Our study investigates the effects of perinatal supplementation with lutein, DHA, and choline in a controlled rat model. The results show: (1) strictly sex‐specific effects exclusively observed in female rats, (2) lutein‐dependent and synergistic effects, (3) enhancement of long‐term recognition memory, and (4) no effects on locomotor activity, anxiety‐

Effect of oxytocin on free intracellular Ca2+ levels and progesterone release by human granulosa-lutein cells [PDF]

, 1993
Oxytocin and its receptor are found in the corpus luteum in a variety of species, including the human. In the present study we used fura-2 microfluorimetry to investigate whether activation of the oxytocin receptor of cultured human granulosa-lutein ...
