Angélica M Jaramillo et al.
PloS one, 13(12), e0209702-e0209702 (2018-12-29)
The most commonly used method for measuring carotenoid concentration is high-performance liquid chromatography (HPLC). Nevertheless, easier, quicker, and less costly proxy methods exist. We aimed to determine the diagnostic performance of several proxy methods: the spectrophotometer, iCheck Carotene, and near-infrared

Acta anaesthesiologica Scandinavica, 44(3), 236-240 (2000-03-14)
Acute renal failure (ARF) can be triggered or aggravated by reactive oxygen species (ROS) but established ARF per se might also affect the antioxidant defence mechanisms of the organism. We evaluated a broad pattern of antioxidants in critically ill patients
Jesús Vioque et al.
Nutrition journal, 12, 26-26 (2013-02-21)
Studies exploring the role of diet during pregnancy are still scarce, in part due to the complexity of measuring diet and to the lack of valid instruments. The aim of this study was to examine the reproducibility and validity (against

Luis M San-Jose et al.
The American naturalist, 181(3), 396-409 (2013-03-02)
Abstract Carotenoids typically need reflective background components to shine. Such components, iridophores, leucophores, and keratin- and collagen-derived structures, are generally assumed to show no or little environmental variability. Here, we investigate the origin of environmentally induced variation in the carotenoid-based

Biochemical and biophysical research communications, 439(1), 137-141 (2013-08-15)
We reported, in previous experiments, that AA is a global regulator of cAMP pools. In this study, we demonstrate that K873, an analog of AA we synthesized and presenting antiproliferative properties, has also an impact on cAMP production. However, K873

β-Carotene is the major dietary source of provitamin A. Central cleavage of β-carotene yields 2 molecules of retinal followed by further oxidation to retinoic acid. Eccentric cleavage of β-carotene occurs at double bonds other than the central double bond, and

Mammalian genomes encode two provitamin A-converting enzymes as follows: the β-carotene-15,15'-oxygenase (BCO1) and the β-carotene-9',10'-oxygenase (BCO2). Symmetric cleavage by BCO1 yields retinoids (β-15'-apocarotenoids, C20), whereas eccentric cleavage by BCO2 produces long-chain (>C20) apocarotenoids. Here, we used genetic and biochemical approaches
