Although linked to a number of adverse health effects, studies of naphthalene are lacking in the exposure-relevant literature. This compound, a major by-product of the incomplete combustion of most organic materials (traffic vehicle exhaust, power ge

VX is one of the most toxic chemical warfare agents. Its low volatility and its persistence in the environment raise the issue of long-term exposure risks, either by inhalation or by transdermal penetration. Therefore, a topic of acute interest is th

The etiological agent of anthrax disease in animals and humans is the spore-forming bacterium Bacillus anthracis. The major factors of virulence of B. anthracis are located on two plasmids, pXO1 and pXO2. pXO2 encodes a poly-d-glutamic acid capsule (

While non-reactivability of cholinesterases from their phosphyl conjugates (aging) is attributed to an unimolecular process involving loss of alkyl group from the phosphyl moiety, no conclusive evidence is available that this is the only reaction pat

Understanding reaction pathways of phosphylation, reactivation, and "aging" of AChE with toxic organophosphate compounds is both a biochemical and a pharmacological challenge. Here we describe experiments which allowed to resolve some of the less wel

Acetylcholinesterases (AChEs) form conjugates with certain highly toxic organophosphorus (OP) agents that become gradually resistant to reactivation. This phenomenon termed "aging" is a major factor limiting the effectiveness of therapy in certain ca

The stereoselectivity of the phosphonylation reaction and the effects of adduct configuration on the aging process were examined for human acetylcholinesterase (HuAChE) and its selected active center mutants, using the four stereomers of 1,2,2-trimet
