A multistage double-blind placebo-controlled study to assess the safety and efficacy of transdermal vitamin D phosphate supplementation (TransVitD).

Background: Lifestyle changes have meant that it is problematic for many people across the globe to maintain adequate vitamin D concentrations. As UV-catalysed production in the skin, which uses vitamin D-binding protein to facilitate systemic absorption, is the primary source of vitamin D, it is questionable if oral supplementation of this vitamin is the optimal means to replace it. However, supplementing an oil-soluble vitamin via the skin is problematic as it gets stuck in the stratum corneum after topical application.

Chayote pectin regulates blood glucose through the gut-liver axis: Gut microbes/SCFAs/FoxO1 signaling pathways.

Despite significant evidence on the anti-diabetic effect of chayote fruit and phenolic compounds, research on the mechanism of chayote (Sechium edule) pectin (CP) regulating blood glucose in type 2 diabetes mellitus (T2DM) is scarce. Therefore, this study aims to explore the potential mechanisms by which CP modulates blood glucose levels through an 8-week administration in db/db mice. The results showed that the CP treatment in db/db mice resulted in an elevation in glucagon-like peptide (GLP-1) secretion, an increase in hepatic glycogen storage, and a decrease in homeostasis model assessment-insulin resistance (HOMA-IR).

Modulation of Molecular Quadrupole Moments by Phenyl Side-Chain Fluorination for High-Voltage and High-Performance Organic Solar Cells.

The ground-state charge generation (GSCG) in photoactive layers determines whether the photogenerated carriers occupy the deep trap energy levels, which, in turn, affects the device performance of organic solar cells (OSCs). In this work, charge-quadrupole electrostatic interactions are modulated to achieve GSCG through a molecular strategy of introducing different numbers of F atom substitutions on the BTA3 side chain. The results show that 8F substitution (BTA3-8F) and 16F substitution (BTA3-16F) lead to different patterns of highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy level changes.
