SR‐B1‐Mediated Transplacental Transfer of Hydrophobic Toxicants Disrupts Fetal Development During Barriergenesis

Advanced Science, Volume 13, Issue 23, 23 April 2026.
This study maps the spatiotemporal distribution of hydrophobic toxicants and endogenous metabolites in the developing placenta and fetus. By integrating mass spectrometry imaging with snRNA‐seq, we identify SR‐B1 as a key transporter driving early‐gestation xenobiotic transfer and reveal a critical exposure window associated with persistent fetal ...

Long‐term effects of moderate and severe hypoxia on growth, intermediary metabolism, monoamine neurotransmitters, and fatty acids in juveniles of coho salmon, Oncorhynchus kisutch

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Hypoxia concerns have increased in recent decades, reducing fish fitness and becoming a critical challenge in salmon aquaculture. We investigated the effect of long‐term hypoxia on the physiological response of coho salmon (Oncorhynchus kisutch).

Enantioselective Determination of Amphetamine‐Type Stimulants in Environmental Waters Using SPE and CE–MS/MS

ELECTROPHORESIS, Volume 47, Issue 3, Page 250-260, March 2026.
ABSTRACT The growing concern over drug abuse, particularly involving amphetamine‐type substances (ATS), has led to their monitoring in environmental waters. These chiral compounds, commonly found in river water and wastewater treatment plant (WWTP) effluents, require analytical methods capable of enantiomeric discrimination, as their enantiomers can ...
