Analysis of Nerve Agent Metabolites from Hair for Long-Term Verification of Nerve Agent Exposure

Analysis of Nerve Agent Metabolites from Hair for Long-Term Verification of Nerve Agent Exposure.

Several methods for the bioanalysis of nerve agents or their metabolites have been developed for the verification of nerve agent exposure. However, parent nerve agents and known metabolites are generally rapidly excreted from biological matrixes typically used for analysis (i.e., blood, urine, and tissues), limiting the amount of time after an exposure that verification is feasible. In this stu...

Pretreatment for Nerve Agent Exposure

Identification of metabolites of nerve agent VX in serum collected from a victim.

A human serum sample collected from a victim of the Osaka VX incident was analyzed according to our developed technique for metabolites of VX. Gas chromatography-mass spectrometry (GC-MS) in full-scan electron impact and chemical ionization modes were used, and, for more reliable confirmation, GC-MS-MS was also employed. In the serum sample, both ethyl methylphosphonic acid and 2-(diisopropylam...

Vagus nerve shwannoma presented with long-term cachexia: report of a case and review of literature

  Abstract   Intraabdominal schwannomas are rare tumors that may arise from viscera or abdominal   wall. The rarity accompanied by occurrence in odds places may make their diagnosis difficult and delayed. We present a case of distal paraesophageal schwannoma with long-term cachexia. A34-year-old man presented with long-lasting vomiting, dysphagia, and progressive cachexia for four years. Multip...

Laboratory Diagnosis of Organophosphates/Nerve Agent Poisoning

Organophosphorus inhibitors of cholinesterases (commonly called organophosphates, OP) are used in industry as softening agents, hydraulic liquids, lubricant additives, plasticizers, antioxidants, and for antiflammable modifications. They are also used in veterinary or human medicine as drugs or chemicals for the study of nervous functions. They differ in their toxicity from practically non-toxi...
