Peak performances in different life domains are often achieved by healthy young- or middle-aged adults and are partly based on their executive functions. The extensive literature on older or non-healthy populations suggests an adequate availability of vitamin D as essential for good executive ...
Studies on the Formation of Vitamins and Their Functions in Hydrocarbon Fermentation : (III) Production of Vitamin B_6 by Several Kinds of Yeasts in Hydroc... Vitamin B_6 production of hydrocarbon-utilizing yeasts was studied using a rotary shaker. Among the species that included Candida, ...
Vitamin A, D, E, and K as Matrix Metalloproteinase-2/9 Regulators That Affect Expression and Enzymatic Activity Fat-soluble vitamins (vitamin A, D, E, and K) assume a pivotal role in maintaining human homeostasis by virtue of their enzymatic functions. The daily incl... HVT Vo,YT Nguyen...
While many people in the U.S. fail to consume recommended levels of vitamin D, the concerns about severe deficiencies are overblown, says Clifford J. Rosen, MD, director of clinical and translational research and a senior scientist at the Maine Medical Center Research Institute in Scarborough, M...
Vitamin D exerts its effects by binding to and activating the vitamin D receptor (VDR). Upon binding vitamin D, the VDR functions as a transcription factor, regulating the activity of over 1,000 different genes.[14] This “genomic” action of vitamin D tends to be slower-acting, requiring...
Vitamin D is a member of the superfamily of nuclear steroid transcription regulators and as such, exerts transcriptional control over a large number of genes. Several other steroids, such as thyroid hormones, vitamin A, androgens and the glucocorticoids, are known as 'neurosteroids' and their role...
Wypasek E, Undas A. Protein C and protein S deficiency—practical diagnostic issues. Adv Clin Exp Med. 2013;22(4):459–67. Acknowledgements We are grateful to the patient for giving his consent to publish this case. We thank Dr. Sadhana Raturi and Dr. Madhurima Kaushik for their valuable...
the membrane protein topology prediction program TMHMM predicts that the probability of the sequence 75–97 functions as a TMD in the full-length VKOR is small (<0.2) (Fig.1A). We have previously shown that VKOR can be altered to a functional 4-TM molecule, the VKOR charge mutant (VK...
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...
Vitamins are a heterogeneous group of organic substances that are present in our natural foods, that are of very high biological potency and that are required in extremely small concentrations for growth and maintenance of normal cells and body function.
