Synergistic Effects of Particulate Matter and Substrate Stiffness on Epithelial-to-Mesenchymal Transition

Thomas H Barker

November 2014
Research Report 182

This report is a study focused on lung tissue repair processes after inflammation and injury resulting from exposure to particulate matter (PM) from combustion sources. Dr. Thomas H. Barker of Georgia Institute of Technology, a recipient of HEI's Walter A. Rosenblith New Investigator Award, and his colleagues tested the hypotheses that alveolar epithelial cells grown on substrates of increasing stiffness would transition to mesenchymal cells — an early step along the pathway to fibrosis — and that the addition of fine PM would enhance these effects.

Development and Application of an Aerosol Screening Model for Size-Resolved Urban Aerosols

Charles O Stanier
Sang-Rin Lee
June 2014
Research Report 179

This report describes a study in which a model to simulate the dispersion of ultrafine particles near roadways was developed and tested. Understanding what happens to ultrafines near roadways – and how that influences exposure – is a key area that HEI's Perspectives 3 on ultrafines (2013) identified. Dr. Charles Stanier at the University of Iowa–Iowa City, a recipient of HEI's Walter A.

Personal Exposure to Mixtures of Volatile Organic Compounds: Modeling and Further Analysis of the RIOPA Data

Stuart Batterman
Feng-Chiao Su

Bhramar Mukherjee
Chunrong Jia
June 2014
Research Report 181

This report describes a study to identify factors that influence exposure to volatile organic compounds (VOCs) and VOC mixtures. Dr. Stuart Batterman at the University of Michigan–Ann Arbor and colleagues used the extensive data that HEI posted on the Web from the Relationships of Indoor, Outdoor, and Personal Air (RIOPA) study (HEI Research Report 130 Parts I and II), and data from the National Health and Nutrition Examination Survey (NHANES), to characterize exposure distributions for 15 VOCs, with an emphasis on high concentrations. Factors examined included geographic location, weather, characteristics of participants' homes, and specific activities, such as pumping gas.

Characterizing Ultrafine Particles and Other Air Pollutants In and Around School Buses

Yifang Zhu
Qunfang Zhang
March 2014
Research Report 180

This report describes a study that assessed levels of ultrafine particles and other pollutants around diesel engine school buses and identified factors contributing to those levels. Dr. Yifang Zhu at the University of California–Los Angeles, a recipient of HEI's Walter A. Rosenblith New Investigator Award, measured pollutant levels in and around school buses while driving, while idling, before and after retrofitting with a diesel particle filter and/or oxidation catalyst, and before and after installing an in-cabin filtration system.

Research Report 175

This report describes semiparametric methods for epidemiologic investigations of the short-term effects of air pollution on health, intended specifically to improve the reliability of point estimates and confidence intervals. Dr. James Robins of the Harvard School of Public Health and colleagues developed the new methods, used simulations to compare them with other methods, and applied them to a large epidemiologic data set from the National Morbidity, Mortality, and Air Pollution Study (NMMAPS) to assess their effectiveness. The report is accompanied by a short editorial to assist the reader in understanding this study and its contributions to epidemiologic methods for air pollution.
