Synergistic Combination of Additive One‐ and Two‐Photon Polymerization Printing Methods to Fabricate 3D Microstructured Perfusable Angiogenesis–on–a–Chip Systems

Engineering in Life Sciences, Volume 26, Issue 1, January 2026.
ABSTRACT Tissue engineering, and in particular the development of organ‐on‐a‐chip (OOC) models, holds significant promise for advancing personalized medicine and reducing the use of animal models. The integration of microfluidics and advanced biomaterials in OOC systems provides controlled microenvironments and fosters the creation of physiologically ...

Automated Diagnosis of Hypertensive Retinopathy Using Res‐UNet and Graph Convolutional Networks

Healthcare Technology Letters, Volume 13, Issue 1, January/December 2026.
The proposed framework integrates retinal vessel segmentation and artery/vein classification using deep residual UNET and GCN models for hypertensive retinopathy diagnosis. By computing the arteriovenous ratio, the method accurately detects HR stages from retinal fundus images. The system achieves reliable performance using the DRIVE dataset.

Clinical Significance of Conjunctival Microvascular Density in Diabetic Retinopathy: A Multimodal Correlation Study Based on Swept‐Source Optical Coherence Tomography Angiography

Journal of Diabetes Research, Volume 2026, Issue 1, 2026.
Diabetic retinopathy (DR) with media opacity presents a diagnostic challenge for retinal evaluation. This study investigated whether conjunctival microvascular assessment using swept‐source optical coherence tomography angiography (SS‐OCTA) can serve as a potential indicator of retinal pathology.
