Non-skeletal activities of vitamin d: From physiology to brain pathology [PDF]
, 2019 Vitamin D is a secosteroid hormone regulating the expression of almost 900 genes, and it is involved in the regulation of calcium and phosphate metabolism, immune response, and brain development.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations
Advanced Functional Materials, EarlyView.Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

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

Impaired release of Vitamin D in dysfunctional adipose tissue: New cues on Vitamin D supplementation in obesity [PDF]
, 2017 Context: Vitamin D accumulates in adipose tissue (AT) and vitamin D deficiency is frequent in obesity. Objective: We hypothesize that trafficking of vitamin D is altered in dysfunctional AT.

Advanced Healthcare Materials, EarlyView.The ability of human induced pluripotent stem cells (hiPSCs) to model developmental processes makes them a promising source for engineering testicular tissues to study in vitro maturation and sperm production. This work describes the first hiPSC‐derived testicular model and shows that it captures functional aspects of prepubertal testicular tissues ...

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.
