In the case of chemical accidents, terrorist attacks, or war, hazardous compounds may be released into the atmosphere. Remote sensing by Fourier-transform infrared spectrometry allows identification and quantification of these hazardous clouds. The output of current standoff detection systems is a yes/no decision by an automatic identification algorithm that analyses the measured spectrum. The ...

objective(s) considering fair response to inhaled corticosteroids and reports of severe air way hyper responsiveness in chemical warfare victims (cwv), a role for eosinophilic inflammation (i.e. asthma) was postulated. the objective of this study was to determine the presence of eosinophilic inflammation in cwv by evaluation of sputum cellularity and eosinophil cationic protein (ecp). materials...

sulfur mustard (sm) has been used as a chemical weapon in some conflicts, and many veterans and civilians have been injured thereby. pulmonary, cutaneous, and ocular effects of sm have been frequently reported, although it seems that other organs such as the cardiovascular system are probably also affected. there are a number of studies evaluating the cardiovascular impacts of sm. however, thes...

background: mustard gas has different effects on different body systems such as respiratory tract, blood, gastrointestinal, skin, eye, endocrine and peripheral nervous system. objectives: the purpose of this study was to determine the quality of life in chemical warfare veterans due to sulfur mustard exposure. patients and methods: in a cross-sectional and analytic study, 242 patients who had a...

The detection and identification of chemical warfare agents is an important analytical goal. Herein, it is demonstrated that 2-chloroethyl ethyl sulfide (half-mustard, CEES) can be successfully analysed using surface-enhanced Raman spectroscopy (SERS). A critical component in this detection system is the fabrication of a robust, yet highly enhancing, sensor surface. Recent advances in substrate...

In this scientific research, MnO2 nanoparticles (NPs) have been successfully prepared by a precipitation method using KMnO4, MnSO4.H2O and H2O2 (30%) as the precursors. As-prepared sample was identified by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and Infrared (IR) techniques. The transmission electron microscopy (TEM) showed 7-8 nm rang...
