The lack of data in the open literature on human exposure to the nerve agent O-ethyl-S-(2-diisopropylaminoethyl) methylphosphonothioate (VX) gives a special relevance to the data presented in this study in which we report the quantification of VX-but

We report a new approach for assessing human exposure to bisphenol A (BPA) by measuring BPA in urine after enzymatic deglucuronidation. This method involves addition of (13)C(12)-labeled BPA, enzymatic deconjugation, solid-phase extraction, and deriv

Levels of non-ortho-substituted (coplanar), mono- and di-ortho-substituted polychlorinated biphenyls, dibenzo-p-dioxins, and dibenzofurans in human serum and adipose tissue

Autor: Wayman E. Turner, L.R. Alexander, Larry L. Needham, Vincent L. Maggio, G D Todd, Donald G. Patterson

Publikováno v: Environmental Health Perspectives

We have measured non-ortho-substituted (coplanar) polychlorinated biphenyl (PCB) levels as well as polychlorinated dibenzo-p-dioxin (PCDD) and polychlorinated dibenzofuran (PCDF) levels in human adipose tissue and serum collected in Atlanta, Georgia.

Publikováno v: Journal of Labelled Compounds and Radiopharmaceuticals. 31:163-174

The synthesis of (±)-[1,1′-15N2, 2′-13C]-trans-3′-methylnicotine is reported. 15N-3-Bromopyridine obtained from bromination of pyridine was formulated with nBuLi/[carbonyl-13C]-methyl formate. The resulting 15N-Pyridine-3-[13C-carbonyl]-carbox

Measurement of toxaphene congeners in pooled human serum collected in three U.S. cities using high-resolution mass spectrometry

Autor: Vincent L. Maggio, Adrian R. Woolfitt, Donald G. Patterson, John R. Barr

Publikováno v: Archives of environmental contamination and toxicology. 46(4)

Because human toxaphene exposure data are largely lacking, we surveyed human serum pools collected from U.S. residents to determine the feasibility of measuring toxaphene in human samples and to determine whether additional analytical requirements we

Publikováno v: Journal of analytical toxicology. 28(5)

One of the most appropriate biomarkers for the verification of organophosphorus nerve agent exposure is the conjugate of the nerve agent to butyrylcholinesterase (BuChE). The phosphyl moiety of the nerve agent can be released from the BuChE enzyme by
