Berberine alleviates cell pyroptosis in diabetic retinopathy by regulating AKT1, JUN, and STAT3

open access: yesIbrain, EarlyView.
Berberine alleviates diabetic retinopathy by reducing pyroptosis through AKT1/JUN/STAT3 regulation, as validated in rat models via network pharmacology, molecular docking, and experimental assays. Abstract Berberine (BBR) exerts an effective protection for diabetic retinopathy (DR), but the underlying key molecular mechanism remains unknown; this study

Poly(2‐Oxazoline)‐Based Polyphotoacids: Synthesis, Solution Behavior, and Cellular Uptake of Multi‐Responsive Intracellular Transporters

open access: yesMacromolecular Rapid Communications, EarlyView.
The ability of photoacids to increase their acidity in response to light irradiation (excited state proton transfer, ESPT) makes them attractive building blocks for the design of stimuli‐responsive copolymers. In this contribution, we present highly biocompatible polyphotoacids based on poly(2‐oxazoline)s bearing 1‐hydroxypyrene units. Low cytotoxicity,

Development and Preliminary Evaluation of a Machine Vision‐Guided Smart Sprayer Prototype Toward Precision Vegetable Weeding

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Sustainable weed management necessitates herbicide‐reduced, precision weed control. Recent advancements in machine vision and artificial intelligence (AI) for weed recognition and localization have created new opportunities for high‐precision weeding. Although blanket spraying systems are widely used for weed removal, machine vision‐guided, AI‐
