The results of the present study have shown that in Micrococcus luteus, light was not an absolute requirement for growth and carotenoid biosynthesis, while molecular oxygen was found to be an absolute requirement for both growth and carotenoid biosynthesis. On the other hand, at stationary phase of growth, the yield of the cells grown in the presence of (0 -24 mM ) nicotine was not significantl...
African eggplants (Solanum aethiopicum and S. macrocarpon) are among the most economically important and valuable vegetable and fruit crops. They are a major source of biologically active nutritional substances and metabolites which are essential for plant growth, development, stress adaptation and defense. Among these metabolites are the carotenoids which act as accessory pigments for photosyn...
Several components of the metabolic syndrome, particularly diabetes and CVD, are known to be oxidative stress-related conditions and there is research to suggest that antioxidant nutrients may play a protective role in these conditions. Carotenoids are compounds derived primarily from plants and several have been shown to be potent antioxidant nutrients. The aim of the present study was to exam...
BACKGROUND There is limited literature on the contributors to isoprostane metabolite 2,3-dinor-5,6-dihydro-15-F(2t)-isoprostane (15-F(2t)-IsoP-M) compared with F(2)-isoprostanes (F(2)-IsoPs) as an oxidative stress biomarker. OBJECTIVE The objective of this study was to investigate whether plasma concentrations of antioxidants, urinary excretion rates of polyphenols, and antioxidants in food a...
Carotenoid turnover was investigated in mature leaves of Arabidopsis (Arabidopsis thaliana) by 14CO2 pulse-chase labeling under control-light (CL; 130 mmol photons m s) and high-light (HL; 1,000 mmol photons m s) conditions. Following a 30-min 14CO2 administration, photosynthetically fixed C was quickly incorporated in b-carotene (b-C) and chlorophyll a (Chl a) in all samples during a chase of ...
Objectives: The study aimed to investigate the effects of Iraqi Lycium barbarm Carotene on normal human blood lymphocytes at molecular level.
 Methods: culture was exposed extracted from estimate interleukins expression in treated represented by IL-10 and TNF-α as a moderator immune response scale, their CD markers changes (CD3, CD4&CD8) flow-cytometer apparatus.
 Results: Total c...
Carotenoid turnover was investigated in mature leaves of Arabidopsis (Arabidopsis thaliana) by 14CO2 pulse-chase labeling under control-light (CL; 130 micromol photons m(-2) s(-1)) and high-light (HL; 1,000 micromol photons m(-2) s(-1)) conditions. Following a 30-min 14CO2 administration, photosynthetically fixed 14C was quickly incorporated in beta-carotene (beta-C) and chlorophyll a (Chl a) i...
