Lysosomal iron accumulation and subsequent lysosomes-mitochondria iron transmission mediate PFOS-induced hepatocyte ferroptosis

Ecotoxicology and Environmental Safety
Perfluorooctane sulfonate (PFOS) is known as a persistent organic pollutant. A significant correlation between PFOS and liver ferroptosis has been unveiled, but the precise mechanism needs to be elucidated. In prior research, we found that PFOS treatment

A rapid and high-throughput quantum dots bioassay for monitoring of perfluorooctane sulfonate in environmental water samples [PDF]

, 2011
Currently HPLC/MS is the state of the art tool for environmental/drinking water perfluorooctane sulfonate (PFOS) monitoring. PFOS can bind to peroxisomal proliferator-activated receptor-alpha (PPARα), which forms heterodimers with retinoid X receptors

PFOS or PreFOS? Are perfluorooctane sulfonate precursors (PreFOS) important determinants of human and environmental perfluorooctanesulfonate (PFOS) exposure? [PDF]

, 2010
The extent to which perfluorooctanesulfonate precursors (PreFOS) play a role in human or environmental exposure to perfluorooctanesulfonate (PFOS) is not well characterized.

Prior Stroke in PFO Patients Is Associated With Both PFO-Related and -Unrelated Factors [PDF]

Frontiers in Neurology, 2020
Background and Purpose: To identify factors associated with prior stroke at presentation in patients with cryptogenic stroke (CS) and patent foramen ovale (PFO). Methods: We studied cross-sectional data from the International PFO Consortium Study (NCT00859885). Patients with first-ever stroke and those with prior stroke at baseline were analyzed for an

Pooled Analysis of PFO Occluder Device Trials in Patients With PFO and Migraine

Journal of the American College of Cardiology, 2021
BACKGROUND Although observational studies have shown percutaneous patent foramen ovale (PFO) closure to be a safe means of reducing the frequency and duration of migraine, randomized clinical trials have not met their primary efficacy endpoints. OBJECTIVES The authors report the results of a pooled analysis of individual participant data from the 2 ...
