Organophosphates, used as chemical warfare nerve agents and pesticides are the most toxic chemicals known to date. Despite the number of studies done on the subject matter, intoxication caused by such agents is among the most complicated problems in medicine because of the induced increase in abnormal electrical activity in the brain and the subsequent brain damage. The anticonvulsant and neuro...

We report the use of carbon nanotubes as a sensor for chemical nerve agents. Thin-film transistors constructed from random networks of single-walled carbon nanotubes were used to detect dimethyl methylphosphonate ~DMMP!, a simulant for the nerve agent sarin. These sensors are reversible and capable of detecting DMMP at sub-ppb concentration levels, and they are intrinsically selective against i...

The nerve agents are chemical warfare agents known to be used during terrorist attacks. An inexpensive and portable system to be used by first responders and military personnel is of interest owing to the continuing threat of possible terrorist attacks. Amperometric biosensors based on cholinesterase inhibition show such potentialities. In this work butyrylcholinesterase was immobilized onto sc...

Chemical warfare agent (CWA) simulants as well as their degradation and hydrolysis products were detected from surfaces using thermal desorption ion mobility spectrometry (TD-IMS). CWA simulant materials that closely mimic the chemical structures of real CWA G/V-type nerve and S-type vesicant simulants were used in this study. Reduced mobility constants (K0) in air were reported for 20 compound...

Background and aim: Chronic skin lesions are common late complications of sulfur mustard intoxication which would result in numerous complaints including pruritus, skin dryness and burn feeling. In chemical warfare injured veterans, pruritus is the most common complaint in chronic status with significant effects on patient's quality of life. This study has evaluated efficacy of topical ph...

In this research urogenital complications of 300 veterans with the average age of 32.7+_6.5 years were studied for two years( 1995-1996) . They were selected randomly in Kerman province based  on having at least one exposure to chemical warfare, six to ten years before the study. The control group was selected among the troops whom were not exposed to chemical warfare and had an average age of ...
