The differential expression of a set of genes encoding antioxidant enzymes and stress-responsive proteins was investigated by real-time quantitative PCR in intestine, liver, and muscle tissues extracted from Oryzias javanicus after exposure to the organophosphorus pesticide, Iprobenfos (IBP). After IBP
Cholinesterases (ChEs) have been characterized in marbled sole (Limanda yokohamae) for use as a possible biomarker of pollution exposure. In brain, ChEs existed almost exclusively (>95%) as acetylcholinesterase (AChE) whereas in muscle, about 20-30% of ChE activity was in the
The sensitive detection of iprobenfos (IBF) and edifenphos (EDI) was successfully conducted by using a new aptamer-based colorimetric multi-aptasensor. The dissociation constants of this multi-target aptamer to both iprobenfos and edifenphos were found to be 1.67 μM and 38 nM
In order to investigate spatial and temporal distribution of organic pollutants in the Saemangeum Bay, organophosphorus pesticides (10), alkylphenols (8), chlorophenols (2), bisphenol A were analyzed from the surface seawater taken in 2002-2003. Most of the analytes were not detected
