Brominated flame retardants (BFRs), hexabromocyclododecanes (HBCDs) and polybrominated diethyl ethers (PBDEs) were detected in three sediment cores and six surface sediments of Tokyo Bay, Japan. HBCDs were detected for the first time in this region with concentrations ranging from 0.056 to 2.3ng/g dry wt, implying their widespread contamination, even though their concentrations were lower than ∑PBDEs...
2'-Deoxyuridine derivatives bearing a substituent at the C5-position, which has a different chain length and a different functional group (methyl or amino), were synthesized and incorporated into oligodeoxyribonucleotides. The effect of the substituent groups in the major groove on the stability of the duplexes was investigated by UV melting experiments. It was found that the stabilization of these...
