Oxidized and electronegative low-density lipoprotein as potential biomarkers of cardiovascular risk in obese adolescents Obese adolescents showed increased plasma LDL(-) and oxLDL, and obese girls had more LDL(-) than obese boys. Therefore, oxLDL is strongly and independently associated with classical cardiovascular risk factors, while increased levels of LDL(-) were influenced by body mass index, waist circumference and demographic parameters in obese adolescents. antioxidants all measured by Chromsystems assays. 2018
Vitamin A Status in Healthy Women Eating Traditionally Prepared Spirulina (Dihé) in the Chad Lake Area We demonstrate that β-carotene in spirulina is an effective positive modulator of blood retinol status and that a natural food compound, Dihè, is a potential natural source of β-carotene to achieve an optimal vitamin A status in healthy women. Vitamin A and ß-carotene measured by Chromsystems assay. 2018
Fortification of vitamin A in a phytosterol enriched milk maintains plasma beta-carotene levels the current study showed that extra fortification of phytosterol-enriched milk with vitamin A is effective enough to reduce serum TC, LDL-C and apo-B levels and at the same time to prevent plasma beta-carotene level reduction that often occurs after plant sterols’ or stanols’ intake. ß-carotene was measured with the Chromsystems assay. 2014
Antioxidant defense and oxidative stress in children with acute hepatitis A The findings show that pediatric patients with acute hepatitis A were influenced by oxidative stress, resulting in significantly lower levels of plasma antioxidants and increased lipid peroxidation. ascorbic acid, α-tocopherol, retinol, β-carotene, and GSH in whole blood were measured by Chromsystems assays.  2011
Antioxidant defense and oxidative stress in children with acute hepatitis A The findings show that pediatric patients with acute hepatitis A were influenced by oxidative stress, resulting in significantly lower levels of plasma antioxidants and increased lipid peroxidation. ascorbic acid, α-tocopherol, retinol, β-carotene, and GSH in whole blood were measured by Chromsystems assays.  2011
Vitamin A and beta-carotene supply of women with gemini or short birth intervals: a pilot study Despite the fact that vitamin A and beta-carotene rich food is generally available, risk groups for low vitamin A supply exist in the western world. Both vitamins measured by Chromsystems HPLC assays. 2007
Antioxidant defense and oxidative stress in children with acute hepatitis A Their research points out that hepatatis A infection causes oxidative stress in children. Antioxidant vitamin supplements could be added to the therapy for these patients to help reestablish the oxidant status balance. However, further investigations to confirm this suggestion are recommended. Ascorbic acid, α-tocopherol, retinol, β-carotene, and GSH, Malondialdehyde measured with Chromsystems assay. 2011

Effect of Supplemental Beta-Carotene on Plasma Concentrations of Carotenoids, Retinol, and Alpha-Tocopherol in Humans The purpose of this study was to assess the effects of long-term daily supplementation with beta-carotene (50 mg/d) on circulating concentrations of other carotenoids, retinol, and alpha-tocopherol over time. Provides data on reference ranges.  1998
