USC Superfund researchers identify “forever chemical” PFHpA as risk factor for severe liver disease in adolescents

Researchers identified a significant association between perfluoroheptanoic acid (PFHpA) exposure and metabolic dysfunction-associated steatotic liver disease (MASLD) in adolescents. The study used advanced models to reveal PFHpA's role in disrupting biological pathways, leading to liver damage and inflammation.

Coherent detector for the non-separability measurement of vectorial structured light

A team of scientists proposed and demonstrated a coherent detector to efficiently detect the non-separability of vectorial structured light. The detector enables single-shot detecting the non-separability with low spatial complexity. Experimental results indicate high efficiency, low complexity, and stability.

New drug-eluting balloon may be as safe and effective as conventional metal stents for repeat percutaneous coronary interventions

A new drug-eluting balloon has been shown to match the outcomes of standard care for in-stent restenosis, offering a safer alternative for patients with multiple stent layers. The study's results suggest that patients with complex or multilayer ISR may benefit from sirolimus-eluting balloons as a viable treatment option.
