Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

Journal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Indole‐Based π‐Extended Monophosphine Ligands for Enhanced Palladium‐Catalyzed Sonogashira Coupling

Journal of Heterocyclic Chemistry, EarlyView.
A general palladium‐catalyzed Sonogashira cross‐coupling of (hetero)aryl chlorides with aliphatic, (hetero)aryl alkynes is described using Pd(dba)₂/PCy2‐Napdole‐phos catalyst system. The reaction protocol exhibits broad substrate scope and the catalyst loading can be down to 0.2 mol% Pd.

Eicosapentaenoic and Docosahexaenoic Acid Levels in Mouse Tissues After Intake of Echium and Ahiflower Oils Rich in Stearidonic and α‐Linolenic Acids

Lipids, EarlyView.
Dietary supplementation with stearidonic acid–rich Echium and Ahiflower oils increases EPA levels across multiple mouse tissues, while DHA responses remain tissue‐specific and limited, supporting the strategic use of plant‐based omega‐3 sources for EPA‐focused interventions. ABSTRACT Omega‐3 fatty acids (n‐3 FA), particularly eicosapentaenoic acid (EPA)
