FAT-SOLUBLE VITAMIN

Supercritical fluid extraction and chromatography for fat-soluble vitamin analysis.

Extraction and chromatographic separation of fat-soluble vitamins is a challenging task, due to the sensitivity of these compounds towards light, oxygen, heat and pH. In light of this, supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC) are attractive techniques as they function at considerably milder conditions than conventional solvent-based analytical techniques...

Fat-Soluble Vitamin Deficiency in Pediatric Patients with Biliary Atresia

OBJECTIVE To analyze the levels of fat-soluble vitamins (FSVs) in pediatric patients with biliary atresia (BA) before and after the Kasai procedure. METHODS Pediatric patients with obstructive jaundice were enrolled in this study. The FSV levels and liver function before, 2 weeks after, and 1, 3, and 6 months after the Kasai procedure were measured. RESULTS FSV deficiency was more obvious i...

Tissue Changes following Deprivation of Fat-soluble a Vitamin

The specific tissue changes which follow the deprivation of fat-soluble vitamin A in albino white rats and in the human concerns epithelial tissues. This effect is the substitution of stratified keratinizing epithelium for normal epithelium in various parts of the respiratory tract, alimentary tract, eyes, and paraocular glands and the genitourinary tract. We have described the morphological se...

Fat and Fat-Soluble Vitamin Supplementation for Improving Reproduction of the Dairy Cow

The scientific literature contains evidence that the nutrient status of lactating dairy cows can have a direct bearing on reproductive status. Pregnancy rate has been improved by manipulating the mineral (Hurley and Doane, 1989), vitamin (Seymour, 2001), energy (Butler, 2001), protein (Butler, 1998), and lipid fractions (Staples et al., 1998) of the diet. Nevertheless the amount of knowledge in...
