Vitamin D Functions Vitamin D[1]: Promotes absorption ofcalciumandphosphatein the intestine.When blood calcium levels are low, vitamin D, stimulated by the parathyroid hormone (PTH), promotes the absorption of calcium and phosphate from the small intestine and bones. When blood calcium levels are...
In target tissues, calcitriol binds to VDR, a member of the nuclear receptor family of ligand-activated transcription factors and which induces both genomic and non-genomic regulation of downstream targets involving diverse biological functions2,27,28. In the genomic pathway, calcitriol binds to cytos...
In the body, Chondroitin functions by attracting fluid to joints to support cushioning and lubrication. Uniflex® (FruiteX-B® Calcium Fructoborate) is a clinically tested mineral complex that supports joint comfort in as little as 2 weeks 1. Hyaluronic Acid (HA) is the same molecule found ...
Oxidative stress occurs when there is an imbalance between the production of free radicals and the detoxification of these reactive products. Regular exercise greatly increases the production of free radicals in humans, while excessive exercise could lead to cellular and tissue damage. This paper presen...
One of the main functions of vitamin D in the body is to increase intestinal calcium absorption and thereby supporting bone density. A combination of vitamin D and calcium supplements to nursing home residents has shown to increase bone density and reduce fracture risk [6, 9]. Therefore, since...
英语翻译They are different in that their elements are arranged differently,and each vitamin performs one or more specific functions in the body.Getting enough vitamins is essential to life,although the body has no nutritional use for excess vitam
We analyze 25 different bacterial species and establish their ability to modulate the predatory feeding behaviors including surplus killing. Subsequently, by focusing on one bacterial species in which surplus killing is strongly enhanced, Novosphingobium, we conduct a mutant screen and identify bacterial ...
Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people ...
(years between randomization and each assessment), treatment assignment, and their interaction63. We fitted models by maximum likelihood, incorporating the longitudinal correlation within participants (using unstructured covariance structure); for statistical testing, we used Wald tests. We calculated ...
[1]. The vitamin D endocrine system regulates calcium homoeostasis and a range of physiological functions such as cell growth, proliferation, differentiation, immune function, inflammation, and apoptosis [2]. A broad spectrum of diseases has been related to vitamin D deficiency and research, to ...
