Three trials using 240 weanling pigs were conducted during winter months to determine the influence of nursery temperature ("comfortable" vs "cold") on the response of weanling pigs to added vitamin C (700 ppm) or E (55 IU/kg) to a corn-soybean meal diet. A "comfortable" temperature schedule (27 C initially with a weekly 2 C drop) was maintained in one nursery, with the temperature schedule in ...

The B-vitamins comprise a group of eight water soluble vitamins that perform essential, closely inter-related roles in cellular functioning, acting as co-enzymes in a vast array of catabolic and anabolic enzymatic reactions. Their collective effects are particularly prevalent to numerous aspects of brain function, including energy production, DNA/RNA synthesis/repair, genomic and non-genomic me...

The water-soluble vitamin (included vitamin B1, B6, B12 and C) preparations are not always replenished when peripheral parenteral nutrition (PPN) is used in Japan. We evaluated the need for administration of vitamins preparation during PPN, and involved analysis of the blood levels of water-soluble vitamins in patients receiving perioperative PPN before and after gastrectomy. Patients were exam...

A T THE TIME when an increasing number of clinical conditions were recognized as deficiencies of one or another chemical substance, such so-called vitamins were measured by their effect as supplement to a basal diet upon the growth and health of some species of laboratory animals. Vitamins are organic substances of natural origin, required in minute quantities, and their effects are not based o...

The potency of oil-soluble vitamins (vitamins A, D, E and K) in fortified foods can be improved by understanding how food matrices impact their bioavailability. In this review, the major matrix effects influencing bioavailability are highlighted: oil content, composition, particle size, interfacial properties, additives. Droplet size aggregation state human gut vitamin modulating lipid digestio...

Seed priming with vitamins is an efficient method for increasing seedlings growth and productivity under stressful conditions. This study aimed to investigate the priming of broad bean (Vicia faba L.) seeds using 100 mg L ascorbic acid and nicotinamide and to study their interactions on growth and some physiological parameters of plant under salt stress (150 mM NaCl) for 4 weeks. Salinity treat...

A high-performance liquid chromatography method is developed for the simultaneous determination of menadione, retinyl acetate, cholecalciferol, alpha-tocopherol, and alpha-tocopherol acetate in feed. The present study uses an enzyme to destroy the coating film, ethanol to extract free vitamins, and Oasis HLB cartridges to purify. Vitamins are separated using an Atlantis dC18 column. The mobile ...

BACKGROUND Abetalipoproteinemia (ABL) is a metabolic disorder resulting in poor absorption of fat-soluble vitamins. CASE Two pregnancies in a woman with ABL are reported, contrasting outcomes with subtherapeutic and normal vitamin levels. CONCLUSION Fat-soluble vitamin levels in pregnancy are critical for many aspects of fetal development. This report details a congenital ophthalmologic fin...
