Objective: To determine the relationship between blood serum lipophilic antioxidant levels and cognitive function (CF) in older adults aged 60 and above guided by the oxidative stress theory of aging.
Methods: Cross-sectional data from the National Health and Nutrition Examination Survey ( = 291) for older adults aged 60 and above were examined using Pearson correlation coefficient and multiple linear regression to determine whether blood serum antioxidant status predicted CF while controlling for age, sex, race, hypertension, smoking status, and body mass index.
Results: Alpha-tocopherol, retinyl palmitate, trans-lycopene, and retinyl stearate were all significantly correlated with CF. After controlling for covariates, α-tocopherol and retinyl palmitate were associated with CF. Age, sex, and current smoking status were significant predictors of CF.
Conclusions: The benefits of antioxidants in CF may be a part of nutritional recommendations which include α-tocopherol and retinyl palmitate for delay of CI, and subsequently a better quality of life.

Background: Understanding the size and surface charge (ζ-potential) of particles in the mixed micellar fraction produced by in vitro digestion is crucial to understand their cellular absorption and transport. The inconsistent presentation of micellar size data, often limited to average particle diameter, makes comparison of studies difficult. The present study aimed to assess different size data representations (mean particle diameter, relative intensity- or volume-weighted size distribution) to better understand physiological mixed micelle characteristics and to provide recommendations for size reporting and sample handling.

Food fortification is an effective strategy to combat vitamin A deficiency. Gari, a cassava-based West African food product, is an interesting product to fortify with vitamin A, but the low stability of vitamin A poses a challenge. We showed that toasted wheat bran can stabilise vitamin A as retinyl palmitate (RP) during storage of RP-fortified gari to a limited extent.

Intravaginal drug administration offers several advantages over other routes, primarily bypassing the initial stages of metabolism. Additionally, this route has demonstrated both local and systemic effects. Mucoadhesive polymeric systems can be utilized to prevent dose loss due to the mucous barriers and the formation of wet cavities.

Retinol and retinyl palmitate, with excellent whitening and antioxidant activities, are widely used as essential functional ingredients in transdermal preparations and skincare products. Herein, for the first time, the influence and underlying mechanisms of retinol and retinyl palmitate on the skin penetration of caffeine are investigated. It is found that the penetration of caffeine is very significantly enhanced by retinol and retinyl palmitate with 2.
