Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

Laser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

Portal Hypertension &Cirrhosis, EarlyView.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...

Sono‐Vasomics With Super‐Resolution Contrast‐Enhanced Ultrasound (SR‐CEUS) for Characterization of Focal Liver Lesions: A Case Report

Portal Hypertension &Cirrhosis, EarlyView.
ABSTRACT Accurate differentiation between benign and malignant focal liver lesions (FLLs) remains a major diagnostic challenge. Vasomics, an emerging discipline, classifies vascular phenotypes into anatomical, biomechanical, biochemical, pathophysiological, and composite categories. Sono‐Vasomics, the ultrasound‐based subset, leverages super‐resolution

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

Small, EarlyView.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Development of an inhalable contrast agent targeting the respiratory tract mucus layer for pulmonary ultrasonic imaging

Scientific Reports
Impaired mucociliary transport is a distinguishing sign of cystic fibrosis, but current methods of evaluation are invasive or expose young patients to ionizing radiation. Contrast-enhanced ultrasound imaging may provide a feasible alternative.
