Inclusion of Vitamin A Intake Data Provides Improved Compartmental Model-Derived Estimates of Vitamin A Total Body Stores and Disposal Rate in Older Adults.

Sampling times and study duration impact estimates of kinetic parameters and variables including total body stores (TBS) and disposal rate (DR) when compartmental analysis is used to analyze vitamin A...

Lean body mass accretion is elevated in response to dietary vitamin D: A dose-response study in female weanling rats.

Vitamin D status positively relates to lean body mass in infants. This study tested the effect of vitamin D on body composition and growth-related hormones. It was hypothesized that low vitamin D stat...

Causal link between vitamin D and total testosterone in men: A mendelian randomization analysis.

Low circulating vitamin D levels have been associated with lower total testosterone. These epidemiological associations, if true, would have public health importance, since vitamin D deficiency is com...

Aggregate exposure modelling of vitamin A from cosmetic products, diet and food supplements.

Realism is important in estimating consumer exposure to a substance, especially when accounting for exposure from multiple sources. Humans are exposed to vitamin A from food, dietary supplements and c...

Estimation of Total Skeletal Content of Plutonium and 241Am From Analysis of a Single Bone.

The skeleton is one of the major retention sites for internally deposited actinides. Thus, an accurate estimation of the total skeleton content of these elements is important for biokinetic modeling a...

Total Body Vitamin A Before and After Vitamin A Supplementation in a Community Where Liver is Frequently Eaten

This study will assess total body vitamin A pool size, as well as liver vitamin A stores, by means of stable isotope dilution in preschool children from a South African community where liv...

Accuracy of Visual Range of Motion Estimates

Examine the accuracy of visual estimates of various joint angles by physical therapists at various levels of education and clinical practice, taking into account years of experience, areas...

Accuracy of OPS™ Femoral Neck Resection Study

The primary objective of this study is to determine the accuracy of the Optimized Positioning System (OPS™) planning and delivery tools using different types of surgical approaches.

Determinants of Vitamin K Metabolism

The purpose of this study is to learn how the body responds to different amounts of vitamin K in the diet in order to understand the roles that vitamin K may have in the body. We also nee...

Study on the Correlation of Free Vitamin d With BMD and Fracture

According to the free hormone hypothesis, the biological activity of a hormone is carried by the portion that is not bound to protein or its carrier in circulation. Based on this, we belie...

Medical and Biotech [MESH] Definitions

A statistical tool for detecting and modeling gene-gene interactions. It is a non-parametric and model-free approach.

A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.

A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)

OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.

VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). Most of vitamin B6 is eventually degraded to PYRIDOXIC ACID and excreted in the urine.
