Vitamin D3: research breakthroughs and therapeutic use
Annals of Mechnikov's Institute, 2019 Vitamin D3 (cholecalciferol), the natural form of vitamin D, is produced in the skin from 7-dehydrocholesterol. The synthesis of vitamin D in the skin is the most important source of vitamin D.

pH-Mediated Regulation of Polymer Transport Through SiN Pores [PDF]
, 2018 We characterize the pH controlled polymer capture and transport thorough silicon nitride (SiN) pores subject to protonation. A charge regulation model able to reproduce the experimental zeta potential of SiN pores is coupled with electrohydrodynamic ...

Anticancer activity of VDR-coregulator inhibitor PS121912 [PDF]
Cancer Chemotherapy and Pharmacology, 2014 PS121912 has been developed as selective vitamin D receptor (VDR)-coregulator inhibitor starting from a high throughput screening campaign to identify new agents that modulate VDR without causing hypercalcemia. Initial antiproliferative effects of PS121912 were observed that are characterized herein to enable future in vivo investigation with this ...

Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro
Journal of Applied Toxicology, EarlyView.ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...

Vitamin D receptor expression is essential during retinal vascular development and attenuation of neovascularization by 1, 25(OH)2D3. [PDF]
PLoS ONE, 2017 Vitamin D provides a significant benefit to human health, and its deficiency has been linked to a variety of diseases including cancer. Vitamin D exhibits anticancer effects perhaps through inhibition of angiogenesis. We previously showed that the active

Electrode geometry and preferential stimulation of spinal nerve fibers having different orientations: a modeling study [PDF]
, 1992 In a computer modeling study of epidural spinal cord stimulation using a longitudinal array of electrode contacts, the effect of contact geometry and contact combination on the threshold voltages for stimulation of dorsal column (DC) fibers and dorsal ...

Novel N-Terminal Variant of Human VDR [PDF]
Molecular Endocrinology, 2001 The importance of N-terminal regions of nuclear hormone receptors in transcriptional regulation is increasingly recognized. As variant VDR gene transcripts indicated possible N-terminally extended receptors, we investigated their natural occurrence, transactivation capacity, and subcellular localization. A novel 54-kDa VDRB1 protein, in addition to the

Coherent Quantum Ratchets Driven by Tunnel Oscillations
, 2009 We demonstrate that the tunnel oscillations of a biased double quantum dot can be employed as driving source for a quantum ratchet. As a model, we use two capacitively coupled double quantum dots.

Transverse tripolar spinal cord stimulation: Theoretical performance of a dual channel system [PDF]
, 1996 A new approach to spinal cord stimulation is presented, by which several serious problems of conventional methods can be solved. A transverse tripolar electrode with a dual-channel voltage stimulator is evaluated theoretically by means of a volume ...
