The concentrations and distributions of some typical chlorinated flame retardants (Dechlorane or Mirex, Dechlorane 602 (Dec 602), Dechlorane 603 (Dec 603), Dechlorane 604 (Dec 604) and Dechlorane Plus (DP)) and brominated FRs (polybrominated diphenyl ethers (PBDEs), pentabromoethylbenzene (PBEB) and 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE)) were analyzed in surficial sediment collected from...

Despite different starting points, in the cloister and world respectively, Anselm of Canterbury (1033-1109) C. S. Lewis (1898–1963) enjoyed a mutual interest concept experience spiritual desire. Inspired by Lewis’ famous sermon, ‘The Weight Glory’ (1941), but principally guided Anselm’s reflections, this essay argues that desire exists dynamic relationship with love that, as journey desire, Chr...

Activation of cyclic nucleotide-gated (CNG) ion channels involves a conformational change in the channel protein referred to as the allosteric transition. The amino terminal region and the carboxyl terminal cyclic nucleotide-binding domain of CNG channels have been shown to be involved in the allosteric transition, but the sequence of molecular events occurring during the allosteric transition ...

Pyrophosphate (PPi) participates in many biological and chemical processes such as energy transduction so that investigations on its role and detection have become very significant. In this contribution, we have developed a molecular logic gate for the recognition of PPi with a fluorescent hypocrellin A-zinc(II) complex (HA-Zn(2+)), and the outputs of which correspond to the fluorescence emissi...
