Proteomic Analysis of Tears as a Promising Method for Diagnosing Dry Eye Syndrome

Oftalʹmologiâ
One of the most common diseases of the organ of vision, characterized by a loss of homeostasis of the tear film, with a violation of the stability of the tear film and its hyperosmolarity, is the dry eye syndrome (DES).

EFFECT OF SYSTEMIC STEROIDS ON TEAR FILM STABILITY

Insights-Journal of Health and Rehabilitation
Background: Systemic corticosteroids are widely prescribed for managing inflammatory and autoimmune conditions; however, their impact on ocular surface health, particularly tear film stability, remains underexplored. Alterations in tear production can compromise visual comfort and ocular integrity, making it essential to assess the potential ocular ...

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

Advanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.
