In pulmonary toxicity screening tests in which the epithelial lining fluid (ELF) is sampled by bronchoalveolar lavage (BAL), investigators have observed both increases and decreases in alkaline phosphatase (AP) activity in BAL fluid during an acute inflammatory response. Such alterations in AP activity are difficult to interpret because of uncertainties(More)
While inhaled polycyclic aromatic hydrocarbons have long been suspected to induce lung cancer in humans, their dosimetry has not been fully elucidated. A key question is whether the critical exposure occurs during absorption in the lungs, or if toxicants in the systemic circulation contribute significantly to lung cancer risk. In particular, data are needed(More)
Traumatic brain injury (TBI) is a leading cause of death and disability in the USA. To help understand and better predict TBI, researchers have developed complex finite element (FE) models of the head which incorporate many biological structures such as scalp, skull, meninges, brain (with gray/white matter differentiation), and vasculature. However, most(More)
