Chemical warfare agents (CWAs) as well as biological toxins present a significant inhalation injury risk to both deployed warfighters and civilian targets of terrorist attacks. Inhalation of many CWAs and biological toxins can induce severe pulmonary toxicity leading to the development of acute lung injury (ALI) as well as acute respiratory distress(More)
Mesenchymal stem cells (MSCs) are multipotent cells located within various adult tissues. Recent literature has reported that human bone marrow-derived MSCs express active acetylcholinesterase (AChE) and that disruption of AChE activity by organophosphate (OP) chemicals decreases the ability of MSCs to differentiate into osteoblasts. The potential role of(More)
Organophosphorus (OP) pesticides are known to induce pulmonary toxicity in both humans and experimental animals. To elucidate the mechanism of OP-induced cytotoxicity, we examined the effects of parathion and malathion and their respective metabolites, paraoxon and malaoxon, on primary cultured human large and small airway cells. Exposure to paraoxon and(More)
Environmental surface sampling is crucial in determining the zones of contamination and overall threat assessment. Viability retention of sampled material is central to such assessments. A systematic study was completed to determine viability of vegetative cells under nonpermissive storage conditions. Despite major gains in nucleic acid sequencing(More)
