Fully Automated Deep Learning Enabled Miniature Mass Spectrometry System for Psychoactive Therapeutic Drug Monitoring

Advanced Science, EarlyView.
This study presents a fully automated miniature mass spectrometry system for high‐throughput therapeutic drug monitoring. Integrating magnetic solid‐phase extraction, self‐aspiration sampling miniature mass spectrometer, and U‐net deep learning quantitative algorithm, it achieves rapid (8 samples/30 min), precise (R2 > 0.99, RSD < 10%), and portable ...

Size-dependent vector effects of microplastics on bioaccumulation of hydrophobic organic contaminants in earthworm: A dual-dosing study

Environment International
The potential of microplastics to act as a vector for anthropogenic contaminants is of rising concern. However, directly quantitatively determining the vector effects of microplastics has been rarely studied.

CXCL6 Reshapes Lipid Metabolism and Induces Neutrophil Extracellular Trap Formation in Cholangiocarcinoma Progression and Immunotherapy Resistance

Advanced Science, EarlyView.
CXCL6's function in cholangiocarcinoma is underexplored. Here it is discovered that CXCL6 is upregulated in cholangiocarcinoma tissues and promotes proliferation and metastasis of it. CXCL6 functions through the CXCR1/2‐JAK‐STAT/PI3K axis and reshaping tumor lipid metabolism.
