Abstract Zn status may affect fatty acid (FA) metabolism because it acts as a cofactor in FA desaturase and elongase enzymes. supplementation affects the desaturases of Zn-deficient rats, but whether this occurs humans is unclear. We evaluated associations between baseline plasma (PZn) concentration total phospholipid composition, well effect daily consumption Zn-fortified water on Beninese children. A 20-week, double-blind randomised controlled trial was conducted 186 school age The...

Abstract The combined sandwich-ELISA (s-ELISA; VitMin Lab, Germany) and the Quansys Q-Plex™ Human Micronutrient Array (7-Plex) are multiplex serum assays that used to assess population micronutrient status in low-income countries. We aimed compare agreement of five analytes, α -1-acid glycoprotein (AGP), C-reactive protein (CRP), ferritin, retinol-binding 4 (RBP4) soluble transferrin receptor (sTfR) as measured by 7-Plex s-ELISA. Serum samples were collected between March 2016 December 2017....

Although the vitamin A (VA) equivalency of provitamin carotenoids from single foods or capsules has been studied using several approaches, there is currently no reliable method to determine VA for mixed diets.To reach objective identifying a in diets, we tested new approach preformed as proxy A.We 6 theoretical subjects who were assigned physiologically plausible values dietary intake, retinol kinetic parameters, plasma pool size, and total body stores. Using features Simulation, Analysis...
