Contrast‐enhanced CT—Nephrotoxic or not? A critical review of propensity‐score‐adjusted studies

Journal of Internal Medicine, Volume 300, Issue 1, Page 5-25, July 2026.
Abstract Retrospective, propensity‐score‐adjusted (PSA) studies have indicated to practitioners in the field that contrast‐induced acute kidney injury (AKI) after contrast‐enhanced CT (CECT) is of minor importance or even non‐existent. This has led to controversies between clinicians demanding CECT not to miss any diagnoses and radiologists reluctant ...

S100A4 Orchestrates Fibroblast Fate to Drive Fibrotic Remodeling

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Fibrotic stimuli induce S100A4 expression, promoting the activation of apoptosis‐resistant fibroblasts through engagement of ERK‐associated signaling. In fibroblasts, S100A4 orchestrates fibroblast fate by enhancing migration, promoting stress fiber formation, increasing ECM contractility, upregulating α‐SMA expression, and supporting survival ...

Soft Neural Interfaces for Circuit‐Level Analysis of Magnetogenetic Deep Brain Stimulation in Parkinson's Disease Models

Advanced Healthcare Materials, Volume 15, Issue 22, 12 June 2026.
ABSTRACT Magnetogenetic deep brain stimulation (MG‐DBS) represents a wireless neuromodulation that has demonstrated long‐lasting behavioral benefits in Parkinson's disease models. However, the circuit‐level mechanisms underlying these therapeutic effects have remained uncharacterized due to limitations of conventional neural interfaces.

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

Advanced Healthcare Materials, Volume 15, Issue 23, 19 June 2026.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic
