Phosphotriesterase (PTE) from soil bacteria is known for its ability to catalyze the detoxification of organophosphate pesticides and chemical warfare agents. Most of the organophosphate chemical warfare agents are a mixture of two stereoisomers at the phosphorus center, and the S(P)-enantiomers are significantly more toxic than the R(P)-enantiomers. In previous investigations, PTE variants wer...

Chemical warfare agents containing phosphonate ester bonds are among the most toxic chemicals known to mankind. Recent global military events, such as the conflict and disarmament in Syria, have brought into focus the need to find effective strategies for the rapid destruction of these banned chemicals. Solutions are needed for immediate personal protection (for example, the filtration and cata...

Multifunctional ultra-high vacuum apparatus for studies of the interactions of chemical warfare agents on complex surfaces Report Title A fundamental understanding of the surface chemistry of chemical warfare agents is needed to fully predict the interaction of these toxic molecules with militarily relevant materials, catalysts, and environmental surfaces. For example, rules for predicting the ...

Iraq has used chemical warfare agents in recent Iran-Iraq conflict ( 1980-88) . There are few studies regarding late complications of chemical warfare and there is no report concerning late cutaneous complications. The present study is concerned with the late clinical manifestation of cutaneous complications in chemical warfare casualties in comparison to non – chemical injured soldiers. Upon t...

in the present work we studied the incidence of fetal deaths among conceptions whose fathers or both parents were survivors of chemical warfare attacks by iraq. we showed that there was significant correlation between frequency of fetal deaths among conceptions which eventuated after exposure of the parents to gas bombs compared to the frequency of fetal deaths among the control group. this wor...

Chemical and biological warfare agents (CBWA's) are diverse in nature; volatile acute low-molecular-weight toxic compounds, chemical warfare agents (CWA's, gaseous choking and blood agents, volatile nerve gases and blister agents, nonvolatile vomit agents and lacrymators), biological toxins (nonvolatile low-molecular-weight toxins, proteinous toxins) and microbes (bacteria, viruses, rickettsiae...

INTRODUCTION The threat of mass casualties caused by an unconventional terrorist attack is a challenge for the public health system, with special implications for emergency medicine, anesthesia, and intensive care. Advanced life support of patients injured by chemical or biological warfare agents requires an adequate level of personal protection. The aim of this study was to evaluate the person...

Iraq has used extensively chemical warfare agents in recent Iran-Iraq conflict (1980-1988) and it is believed about 450,000 people were exposed to this agents. Long-term effects of chemical warfare agents, particularly mustard gas, on pulmonary function tests (PFT) (VC, FEV1 , FVC, FEV/FVC, PEF, MEF50%, MEF25%, MEF25-75% , ERC and IC) are estimated during 7.7 [standard deviation (SD)=l.2] years...
