Vitamin A Kinetics and Supplementation in Neonates

Vitamin A is an essential micronutrient required for normal embryonic and neonatal development, in terms of growth, vision, lung development, and immunity. However, not much is known about the metabolism of vitamin A in the neonatal period. In collaboration with researchers from Pennsylvania State University, this NIH-funded project aims to study the whole-body metabolism and kinetics of vitamin A in neonatal rats as well as the effects of different forms of vitamin A supplementation on the kinetics.

Vitamin A on Neonatal Adipose Tissue Development

Retinoic acid, the active metabolite of vitamin A, is known to be a key regulator of adipose tissue development in adult obese models. However, little is known about the effect of vitamin A or retinoic acid on obesity-associated developmental and metabolic conditions in early life. In this project, through a series of studies using Sprague-Dawley rats as the animal model, we assess the effects of dietary vitamin A supplementation or retinoic acid treatment on the adipose tissue development and associated metabolic conditions of neonatal rats from mothers consuming an obesogenic diet.

Lutein and Retinopathy of Prematurity 

Funded by Sigma Xi Grants in Aid of Research, this project aims to study the role of lutein, delivered by nanoemulsions, in the progression of retinopathy of prematurity (ROP) in preterm newborn rats. ROP is an eye disorder that affects ~32% of hospitalized preterm babies in the U.S. and is a leading cause of blindness among them. Lutein is a dietary antioxidant and the main component of the macular pigment to protect against light-initiated oxidative damage. Its concentration in the eyes of preterm infants was found to be significantly reduced.

Nanoencapsulation on Bioavailability of Biocompounds

In this project, we are developing supramolecular guest-host structures, including starch-guest inclusion complexes, as delivery systems for micronutrients and phytochemicals, so they can be protected against the adverse environment, and their bioavailability may be increased. Bioactive compounds that have been tested include lutein, beta-carotene, vitamin D, ascorbyl palmitate, retinyl palmitate, catechin, and phenolic acids.

Nutritional Quality of Microgreens

Microgreens are young and tender vegetable greens, and represent an exotic class of specialty crops. This project seeks to study the contents and bioavailability of phytochemicals and nutrients, especially those having antioxidant properties, in microgreens.

Phenolics on Starch Digestion and Glucose Homeostasis

Phenolic compounds are secondary metabolites produced in plants as a response to stressors. A large variety of phenolic compounds, e.g., phenolic acids, flavonoids, and tannins, have been documented to inhibit starch digesting enzymes. This project explores the effects of various phenolics on the in-vitro and in-vivo starch digestion kinetics as well as on glucose homeostasis.
