Among the Weapons of Mass Destruction, chemical warfare (CW) is probably one of the most brutal created by mankind in comparison with biological and nuclear warfare. Chemical weapons are inexpensive and are relatively easy to produce, even by small terrorist groups, to create mass casualties with small quantities. The characteristics of various CW agents,(More)
Zinc oxide nanoparticles (ZnO-NPs) are increasingly used in sunscreens, biosensors, food additives, pigments, rubber manufacture, and electronic materials. With the wide application of ZnO-NPs, concern has been raised about its unintentional health and environmental impacts. This study investigates the toxic effects of ZnO-NPs in human lung cells. In order(More)
Currently available vaccines for the pandemic Influenza A (H1N1) 2009 produced in chicken eggs have serious impediments viz limited availability, risk of allergic reactions and the possible selection of sub-populations differing from the naturally occurring virus, whereas the cell culture derived vaccines are time consuming and may not meet the demands of(More)
Increased levels of particulate air pollution are associated with increased respiratory and cardiovascular mortality and morbidity. Some epidemiologic and toxicological researches suggest ultrafine particles (<100 nm) to be more harmful per unit mass than larger particles. In the present study, the effect of particle size (nano and micro) of carbon black(More)
The recent bioterrorist attacks using anthrax spores have emphasized the need to detect and decontaminate critical facilities in the shortest possible time. There has been a remarkable progress in the detection, protection and decontamination of biological warfare agents as many instrumentation platforms and detection methodologies are developed and(More)
DFP in acute dose (2 mg/kg i. p.) in mice significantly inhibited acetylcholinesterase AChE) activity in five regions of brain i.e. cerebral cortex, corpus striatum, medulla, cerebellum and hypothalamus. The inhibition was accompanied by depletion of glycogen from these regions 1 hr after DFP administration. The inhibition of enzyme activity was more in(More)
BACKGROUND Dyshormonogenetic goiter is one of the most common causes of hypothyroidism in children and adolescents in iodine nonendemic areas. The exact genotype-phenotypic correlations (GPCs) and risk categorization of hypothyroid phenotypes of dyshormonogenetic mutations are largely speculative. The genetic studies in pediatric dyshormonogenesis are very(More)
DRDE-07, a newly synthesized amifostine analog currently under clinical investigation in a phase I trial, is a potent antidote against sulfur mustard toxicity. The purpose of this research was to evaluate the pharmacokinetic profile of DRDE-07 in female Swiss Albino mice after a single oral dose of 400 or 600 mg/kg. The physicochemical properties of(More)
OBJECTIVES To find out the analgesic and anti-inflammatory activity, if any, of Amifostine [S-2(3 amino propyl amino) ethyl phosphorothioate], DRDE-07 [S-2(3 amino ethyl amino) ethyl phenyl sulphide] and their analogs DRDE-30 and DRDE-35, the probable prophylactic agent for sulphur mustard (SM). MATERIALS AND METHODS In order to find out the analgesic(More)
