Diagnosis of chronic venous insufficiency [PDF]

open access: yesJournal of Vascular Surgery, 1986
An orderly diagnostic approach is needed to establish specific anatomic and etiologic diagnoses in patients with chronic venous insufficiency. It begins with the history and physical examination, including Doppler examination of the veins, in the office.

Magnetoactive Hydrogels to Probe Curvature‐Directed Endothelial Cell Mechanosensing

open access: yesAdvanced Healthcare Materials, EarlyView.
This work establishes a platform to investigate local curvature as a regulator of endothelial mechanosensing independent of shear stress. Magnetoactive hydrogels enable on‐demand curvature of endothelial monolayers to reproduce tortuosity quantified by clinically established metrics.

Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

open access: yesAdvanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.

Moisture‐Adaptive Triboelectric Materials and Platforms: Design Strategies, Performance Enhancement, and Applications in Energy Harvesting and Wearable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
This review summarizes moisture‐adaptive strategies that enable triboelectric nanogenerators (TENGs) to operate across diverse moisture conditions. It examines moisture‐management methods, including exclusion, directional transport, removal, and utilization, with charge‐regulation approaches based on interfacial, dielectric, and structural engineering.
