Nerve Agents: A Comprehensive Review

Journal of Intensive Care Medicine, 2004
Nerve agents are perhaps the most feared of potential agents of chemical attack. The authors review the history, physical characteristics, pharmacology, clinical effects, and treatment of these agents.

Inhalational exposure to nerve agents

Respiratory Care Clinics, 2004
The respiratory system plays a major role in the pathogenesis of nerve agent toxicity. It is the major route of entry and absorption of nerve agent vapor, and respiratory failure is the most common cause of death follow-ing exposure. Respiratory symptoms are mediated by chemical irritation,muscarinic and nicotinic receptor overstimulation, and central ...

Toxicokinetics of Nerve Agents

2007
This chapter presents the subjects as in the second edition, updated with the latest results on the toxicokinetics of VX, mainly obtained after improvement of the analytical methodology. Toxicokinetic studies, together with toxicodynamic studies of nerve agents, provide a quantitative basis for the design of new strategies against intoxication with ...

Chemical warfare agents: II. nerve agents

Annals of Emergency Medicine, 1992
Nerve agents are highly potent and rapidly acting organophosphorus compounds that irreversibly bind and inactive acetylcholinesterase. Only rarely have they been used in warfare, but their great lethality and the threat that they pose have encouraged production and stockpiling in large quantities.

Degradation and Detection of the Nerve Agent VX by a Chromophore-Functionalized Zirconium MOF

Chemistry of Materials, 2019
Nerve agents are among the most toxic substances known to man. Recent events in Syria, Malaysia, and the UK illustrate that the threat of these substances is real and actual.

Environmental exposure to organophosphorus nerve agents

Environmental Toxicology and Pharmacology, 2017
Exposure to organophosphorus nerve agents, the most deadly chemical warfare agents, is possible in a variety of situations, such as destruction of chemical warfare agents, terrorist attacks, armed conflicts or accidents in research laboratories and storage facilities.

Therapy for Nerve Agent Poisoning

Archives of Neurology, 2004
Neurologists need to familiarize themselves with nerve agents, the most toxic of the chemical warfare agents. Their mode of action lies within the nervous system, and nonneurologists will look to neurologists for expert advice on therapy. These agents cause rapid-onset cholinergic crisis amenable to prompt treatment with specific antidotes.

Degradation of nerve agents by an organophosphate-degrading agent (OpdA)

Journal of Hazardous Materials, 2008
Enzyme-catalysed degradation of the nerve agents tabun, sarin, ethyl sarin and soman by three variants of an organophosphate-degrading enzyme was studied at low concentrations of nerve agent. The concentration of nerve agent at a given time was determined by its ability to inhibit the enzyme acetylcholinesterase.

Behavioral toxicity of nerve agents

2009
Publisher Summary Behavioral changes in humans are exposed to highly toxic organophosphorus (OP) compounds, called nerve agents. The incidence of behavioral effects is higher in individuals who have been severely exposed to nerve agents, but they may occur in individuals who have received a small exposure and have no or minimal physical signs and ...

Sixty seconds on . . . nerve agents [PDF]

BMJ, 2018
The recent attack on Russian former double agent Sergei Skripal and his daughter Yulia with a nerve agent has triggered a meeting of the government’s COBRA emergency committee. A huge clean-up effort by specially trained troops has also been launched to minimise any remaining risk in Salisbury. Back to your biochemistry classes!
