improved use of biomarkers of exposure, effects and susceptibility. For example, one panelist will explore the optimal urinary biomarkers to use in order to examine the dose of combustion products and paving materials. Another panelist will highlight a variety of diseases and then equate these to particulate levels.

MicroRNAs in Biology and Toxicology

The field of microRNAs is relatively new and offers much promise in helping scientists understand mechanisms of toxicity. For example, recent studies have shown that microRNAs have important roles during embryonic development and disruption of microRNA synthesis in embryos can have dramatic consequences. MicroRNAs also are involved in several human studies and appear to regulate cellular responses to a variety of physiological and environmental stressors including diabetes, high blood pressure, nutrient stress hypoxia, and environmental chemicals.

Food Allergy: Basic Mechanisms and Applications to Identifying Risks Associated with Plant Incorporated Pesticides and Other Genetically Modified Crops

Food allergy is a relatively new concern for toxicologists as a result of the incorporation of novel proteins into food crops as a way of promoting resistance to pest and other stresses, improve nutrition or otherwise modify the crop. There is growing concern that the introduction of a novel protein into the food supply could result in the unintentional introduction of a new food allergen and could pose a risk to susceptible individuals. Toxicologists will explore this issue and talk about a number of strategies that have been used to help scientists develop improved hazard identification methods.

The 48th Annual Meeting also features more than 2,000 abstracts that will be presented in poster and platform sessions on a wide array of topics. The event also features 27 symposia, 19 workshops and 14 roundtable discussions, with sessions addressing such topics as neurod
