A pH‐Responsive fluorescence lifetime probe reveals GOT1 phase separation in cellular anti‐senescence

Smart Molecules, EarlyView.
Acidic pH triggers GOT1 phase separation via IDR1, recruiting ME1 to form ROS‐scavenging condensates that combat senescence, revealed by a FLIM‐based pH probe. Abstract Cellular senescence involves progressive acidification, but how cells sense and adapt to this pH shift remains unclear.

Bisphenols and Phthalates in Bottled Mineral Water: First Evidence of Co‐Occurrence, Estrogenic Activity, and Health Risk in Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...
