Naturally Derived Donor‐π‐Acceptor Compounds for Efficient Long‐Wavelength LEDs/Sunlight‐Induced Polymerization and High‐Precision Multiple 3D Printing

Advanced Functional Materials, EarlyView.
Two novel donor–π–acceptor photoinitiators enable ultrafast long‐wavelength photopolymerization under blue/green LEDs and sunlight. Effective at low intensities and concentrations, they overcome slow kinetics and permit rapid 3D printing via DLW, DLP, and LCD methods.

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.

Advances in Stimuli‐Responsive Organic Materials and Polymers toward Intelligent CO2 Capture

Advanced Functional Materials, EarlyView.
Schematic illustration of the relationship between different stimuli and stimuli‐responsive organic materials and polymers for carbon dioxide (CO2) capture. Main stimuli include redox, pH, magnetism, temperature, light, and pressure. Furthermore, multi‐responsive materials, due to their high adaptability and scalability in complex environments, are ...

Microneedle‐Based Biofertilizer Delivery Improves Plant Growth Through Microbiome Engineering

Advanced Functional Materials, EarlyView.
This figure shows how microneedles are used to deliver biofertilizers to enhance plant growth through microbial migration, metabolic reprogramming, and changes in plant endogenous microbiome. Abstract This study presents a microneedle‐based system for the delivery of rhizospheric biofertilizers into plant tissues to enhance growth.

3D Differentiation of Bone‐Marrow Derived Mesenchymal Stromal Cells into the Keratocyte Lineage for Corneal Bioprinting

Advanced Healthcare Materials, EarlyView.
This study introduces a novel differentiation protocol for generating corneal stromal keratocyte‐like cells using drop‐on‐demand bioprinting and a collagen‐based hydrogel. The bioprinted constructs maintained a stable dome shape over 21 days while exhibiting upregulated CSK markers postdifferentiation.

Skeletal and Extraskeletal Actions of Vitamin D: Current Evidence and Outstanding Questions

Endocrine reviews, 2018
The etiology of endemic rickets was discovered a century ago. Vitamin D is the precursor of 25-hydroxyvitamin D and other metabolites, including 1,25(OH)2D, the ligand for the vitamin D receptor (VDR).
