Wohlford-Lenane, Christine L., Daniel C. Deetz, and David A. Schwartz. Cytokine gene expression after inhalation of corn dust. Am. J. Physiol. 276 (Lung Cell. Mol. Physiol. 20): L736–L743, 1999.—To characterize the time course and localize the production of proinflammatory cytokines after inhalation of corn dust, we exposed mice (C3H/HeBFeJ) by inhalation challenge to sterile corn dust extract ...

OBJECTIVES Two- and 13-week inhalation toxicities of indium-tin oxide (ITO) and indium oxide (IO) were characterized for risk assessments of workers exposed to ITO. METHODS F344 rats of both sexes were exposed by inhalation to ITO or IO aerosol for 6 h/day, 5 day/wk for 2 wk at 0, 0.1, 1, 10 or 100 mg/m(3) or 13 wk at 0, 0.1 or 1 mg/m(3). An aerosol generator and inhalation exposure system wa...

Background: Diurnal sequences of activities conducted at several locations visited by individuals have an impact on population exposure to air pollution. However, data on individual's movement with a fine time resolution is rare. Methods: In the current study, 399 children and adolescents (aged 11–18 years) from Isfahan city were asked to recall their 24-hour diary during winter and spring 2014...

The lack of identified exposures in 2 of the 11 cases of bioterrorism-related inhalation anthrax in 2001 raised uncertainty about the infectious dose and transmission of Bacillus anthracis. We used the Wells-Riley mathematical model of airborne infection to estimate 1) the exposure concentrations in postal facilities where cases of inhalation anthrax occurred and 2) the risk for infection in va...

The manuscript embodies case material and the author’s extensive personal experience to address a perceived or actual airborne exposure when incorrectly judged as due to intrathoracic/lung damage when in reality the outcome is the more innocuous extrathoracic/upper airway’s vocal cord dysfunction (VCD). Because of the conviction of possible lung injury, the individual applies the fetal protecti...

Protection experiments were conducted using different doses of equine serum butyrylcholinesterase (Eq BuChE) as pretreatment in rats. Cholinesterase activities were determined in blood [whole blood, red blood cells (RBC) acetylcholinesterase (AChE), and plasma BuChE] before and after sarin inhalation exposure in untreated rats and those pretreated with Eq BuChE. Brain AChE activity was also det...

background: there is no data on the prevalence and the association of gastro esophageal reflux disease (gerd) with toxic fume inhalation. therefore, we aimed to evaluate the frequency distribution of gerd symptoms among the individuals with mild respiratory disorder due to the past history of toxic fume exposure to sulfur mustard (sm). materials and methods: in a historical cohort study, subjec...

Diisocyanates are a group of chemically reactive agents, which are used in the production of coatings, adhesives, polyurethane foams, and parts for the automotive industry and as curing agents for cores in the foundry industry. Dermal and inhalation exposure to methylene bisphenyl isocyanate (MDI) is associated with respiratory sensitization and occupational asthma. However, limited research ha...

A rostro-caudal gradient of uranium (U) in the brain has been suggested after its inhalation. To study factors influencing this mapping, we first used 30-min acute inhalation at 56 mg/m3 relatively soluble form UO4 rat. These exposure parameters were then as a reference comparison with other experimental conditions. Other groups received different concentrations, repeated low dose (10 exposures...
