A Mechanistic Review of β-Carotene, Lutein, and Zeaxanthin in Eye Health and Disease

open access: yesAntioxidants, 2020
Carotenoids are natural lipid-soluble antioxidants abundantly found as colorful pigments in fruits and vegetables. At least 600 carotenoids occur naturally, although about 20 of them, including β-carotene, α-carotene, lycopene, lutein, zeaxanthin, meso ...

Perceptions of Medications and Supplements by U.S. Dog‐Interested Members of the Public and Final‐Year Veterinary Students

open access: yesJournal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Veterinary graduates must be prepared to educate clients about medications and supplements. We surveyed 1955 Dog Aging Project newsletter recipients and 40 final‐year veterinary students at Texas A&M College of Veterinary Medicine and Biomedical Sciences on their perceptions about medications and supplements. Respondents indicated whether each

Photoprotection in the antenna complexes of Photosystem II: role of individual xanthophylls in chlorophyll triplet quenching [PDF]

open access: yes, 2008
In this work the photoprotective role of all xanthophylls in LHCII, Lhcb4, and Lhcb5 is investigated by laser-induced Triplet-minus-Singlet (TmS) spectroscopy.

Desiccation tolerance mechanisms in the green lineage and beyond

open access: yesNew Phytologist, EarlyView.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

Sustainable production of β-Xanthophylls in Saccharomyces Cerevisiae [PDF]

open access: yes, 2018
Xanthophylls are a group of C40 pigments that belong to the carotenoids family. β-Xanthophylls, such as zeaxanthin, violaxanthin and neoxanthin are derived from β-carotene metabolism, and play a central role in the protection of photo-oxidative damage in

Xanthophylls are preferentially taken up compared with beta-carotene by retinal cells via a SRBI-dependent mechanism [PDF]

open access: yes, 2008
The purpose of this study was to investigate the mechanisms by which carotenoids [xanthophylls vs. beta-carotene (beta-C)] are taken up by retinal pigment epithelial (RPE) cells. The human RPE cell line, ARPE-19, was used.

Femtosecond Time-Resolved Transient Absorption Spectroscopy of Xanthophylls [PDF]

open access: yes, 2016
Xanthophylls are a major class of photosynthetic pigments that participate in an adaptation mechanism by which higher plants protect themselves from high light stress. In the present work, an ultrafast time-resolved spectroscopic investigation of all the
