Introduction
Working on a project to characterize persistent contaminants in firefighter protective clothing and help support the development of specific cleaning validation procedures to determine the effectiveness of specific PPE cleaning equipment, cleaning agents and procedures. Fire fighters are at greater risk for cancer than the general public and there are no procedures or requirements to demonstrate whether current cleaning practices actually remove contaminants from firefighter protective clothing.

Surgical N95 filtering facepiece respirators (FFRs), certified by the National Institute for Occupational Safety and Health (NIOSH) as a respirator and cleared by the Food and Drug Administration (FDA) as a surgical mask, are often used to protect from the inhalation of infectious aerosols and from splashes/sprays of body fluids in health care faci...
The dissolution of metal-containing particles in the gastric compartment is poorly understood. The purpose of this study was to elucidate the influence of artificial gastric juice chemical composition on bioaccessibility of metals associated with ingestion-based health concerns. Dissolution rates were evaluated for well-characterized feedstock coba...
Single-wall carbon nanotubes (SWCNTs), with their unique physicochemical and mechanical properties, have many potential new applications in medicine and industry. There has been great concern subsequent to preliminary investigations of the toxicity, biopersistence, pathogenicity, and ability of SWCNTs to translocate to subpleural areas. These resul...
Inhalation of beryllium dusts generated during milling of ores and cutting of beryl-containing gemstones is associated with development of beryllium sensitization and low prevalence of chronic beryllium disease (CBD). Inhalation of beryllium aerosols generated during primary beryllium production and machining of the metal, alloys, and ceramics are...
Inflammation and oxidative stress are associated with cancer, atherosclerosis, and other chronic diseases. Dietary flavonoids have been reported to possess antiinflammatory and antioxidant properties, but their mechanisms of action and structure-activity relations have not been fully investigated. We hypothesized that differences in antioxidant act...
The first author has retracted this paper because of an overlap with Chen, et al, (2002), PNAS 99: 1990-1995, DOI 10.1073/pnas.032428899.
Dietary supplements such as vitamin C have become popular for their perceived ability to enhance the body's antioxidant defenses. Reactive oxygen species (ROS) have been shown to cause a broad spectrum of damage to biological systems. Scavenging of ROS is part of a healthy, well-balanced, antioxidant defense system. The present study used the Fento...
Inhalation of dust from hard metal (HM), a mixture of tungsten carbide, cobalt, and other metals, can cause interstitial alveolitis, fibrosis, and asthma in the workplace. Some effects of HM could occur after the metals dissolve in the lung. We examined whether chloride salts of metals in HM alloys can elicit responses or modify reactivity to metha...
Ozone (O(3)) is toxic to respiratory epithelium and causes airway inflammation and hyperreactivity. To evaluate the role of the epithelium in the development of hyperreactivity, we examined in guinea pigs the effects of inhaled O(3) (3 ppm for 1 h; 0-24 h after exposure) on 1) reactivity to inhaled methacholine (MCh), 2) reactivity of the isolated,...
Inhalation of nonisotonic solutions can elicit pulmonary obstruction in asthmatic airways. We evaluated the hypothesis that the respiratory epithelium is involved in responses of the airways to nonisotonic solutions using the guinea pig isolated, perfused trachea preparation to restrict applied agents to the mucosal (intraluminal) or serosal (extra...
