Moutan Cortex Extract Mediates Diabetic Retinopathy by Blocking the ROS‑Triggered HIF‐1α/VEGF Axis in Retinal Pigment Epithelial Cells

open access: yeseFood, Volume 7, Issue 4, August 2026.
Schematic diagram of the mechanism by which Moutan Cortex extract (MCE) ameliorates DR. MCE alleviates retinal structural damage and reduces neovascular lesions by downregulating the ROS/HIF‐1α/VEGF signaling axis. ABSTRACT Moutan Cortex is a functional food ingredient with multiple health benefits, but its effects on diabetic retinopathy (DR) remain ...

A Solvent‐Free Synthesis of Imidazo[1,5‐a]pyridines Using CCl4 as an Oxidant

open access: yesJournal of Heterocyclic Chemistry, Volume 63, Issue 8, Page 1288-1299, August 2026.
A solvent‐free synthesis of imidazo[1,5‐a]pyridines (Impys) using CCl4 as an oxidant reagent and DBU as the base is informed. An array of Impys derived from different benzylic, heteroaryl aldehydes and others was synthesized in moderate to good yields.

Interaction Between Nitrogen Forms, Phosphorus Forms, and Mineral Phases Drives Phosphorus Limitation and Uptake by Ryegrass in a Model System

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 593-604, August 2026.
Nitrogen addition shifts plant nutrition from nitrogen to phosphorus (P) limitation. Nitrate‐based nitrogen enhances P acquisition more effectively than ammonium through increased phosphatase activity, independently of pH changes. Organic P forms induce stronger P limitation than inorganic P.
