Tree shrew model of early diabetic retinopathy reveals microvascular dysfunction and identifies phosphoserine aminotransferase 1 as a novel therapeutic target

Animal Models and Experimental Medicine, EarlyView.
We developed an animal model of early diabetic retinopathy (DR) in the tree shrew by feeding a high‐fat and high‐sugar diet in combination with STZ. Physiological and biochemical index detection, hematoxylin and eosin staining, and transmission electron microscopy were performed to examine DR.

Synthesis and Characterization of Ag–Fe Bimetallic Nanoparticles and Nanocomposites (Alloys and Core–Shells) for Photocatalytic Degradation of Bromophenol Blue Dye Using Grewia optiva Leaf Extract

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Ag–Fe bimetallic nanoparticles (alloy and core–shell structures) were synthesized using Grewia optiva leaf extract through a green, phytochemical‐mediated approach. The effects of pH, temperature, extract concentration, and Ag:Fe molar ratio on nanoparticle formation were systematically optimized, enabling size‐controlled and morphologically ...

Software‐Defined Terahertz Beam Manipulation via Active Light‐Controlled Frequency Coding Information Metasurface

Advanced Physics Research, EarlyView.
This paper proposes an integrated active light‐controlled frequency coding metasurface and a software‐defined array control system. Utilizing spatially encoded structured light and a “Decision‐Optimization‐Execution” intelligent closed‐loop architecture, the system overcomes traditional electrical control interference, achieves real‐time dynamic ...

Metalens‐Enabled Twisted Chromatic Dispersion

Advanced Physics Research, EarlyView.
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...
