Global vitamin D status problems: causes, pathogenetic mechanisms, treatment, prevention measures
Медицинский совет, 2018 There is a need to improve the status of vitamin D. Vitamin D not only affects the processes of formation of the musculoskeletal system, but also actively participates in many extra-osseous effects of cholecalciferol.

Advanced Functional Materials, EarlyView.Effective electron transfer and stable enzyme immobilization, both between enzymes and host electrodes as well as between adjacent enzymes, are crucial for optimizing the biofuel cell (BFC) performance. Recently, efforts have focused on integrating these strategies with porous host electrodes.

Vitamin D sensitivity to the immune responses and autoimmunity: A chemical network model study [PDF]
arXiv, 2013 Although Vitamin D is believed to be involved in a large number of immune responses our understanding of these processes at cellular level remained at infancy. We develop and solve a coarse grained kinetic network model to quantify the effects of variation of vitamin D on human immunity. The system of equations accounts for known inter-relation between

Rheumatic Disease Clinics of North America, 2010 The biologically active metabolite of vitamin D, 1,25(OH)(2)D(3), affects mineral homeostasis and has numerous other diverse physiologic functions including effects on growth of cancer cells and protection against certain immune disorders. This article reviews the role of vitamin D hydroxylases in providing a tightly regulated supply of 1,25(OH)(2)D(3).

Calculation of the Sun exposure time for the synthesis of vitamin D in Urcuquí, Ecuador [PDF]
Proceeding of Abstracts of IWBBIO, Francisco Ortu\~no Guzm\'an,
Ignacio Rojas Ru\'iz (Comp.), ISBN: 978-84-16929-58-0 (2017), 27, 2017 The synthesis of vitamin D is strongly linked to the availability of solar energy. For a long time, it was clear that using the erythemal irradiances is a good choice to calculate the exposure time. Several authors argue that this method of minimum exposure time overestimates the calculation of the solar irradiance of vitamin D.

A repeated measures approach to pooled and calibrated biomarker data [PDF]
arXiv, 2021 Participant level meta-analysis across multiple studies increases the sample size for pooled analyses, thereby improving precision in effect estimates and enabling subgroup analyses. For analyses involving biomarker measurements as an exposure of interest, investigators must first calibrate the data to address measurement variability arising from usage

Current Dermatology Reports, 2020 The goal of this review is to provide an update in the field of vitamin D, in particular, the role of vitamin D in non-skeletal health, the complexity of providing patient guidance regarding obtaining sufficient vitamin D, and the possible involvement of vitamin D in morbidity and mortality due to SARS-CoV-2 (COVID-19).In addition to bone health ...
