Air pollution has been associated with significant adverse health effects, including increased morbidity and mortality. The global increase in the prevalence of diseases that are associated with exposure to air pollution is of great concern. In particular, severe PM2.5 pollution occurs in Asian countries due to increasing emissions of air pollutants caused by the countries' rapid economic growth. A number of studies have been performed to clarify the association between PM2.5 and disorders such as asthma, ischemic cardiovascular diseases, arteriosclerosis, cancer, and neurological disorders. It is important to protect populations that are susceptible to such pollution. While the characterisation and monitoring of pollutant components currently dictates pollution control policies, it will be necessary to identify susceptible populations in order to adequately target prevention strategies for the health effects of air pollution. This book offers a comprehensive review of the recent advances in our understanding of the health effects of PM2.5, the role of oxidative stress in these effects, the contribution of ultrafine fractions of PM2.5 to the health effects, and discusses prevention strategies for these health effects. It also suggests further risk assessment, risk management, and novel policies for PM2.5 pollution, required to protect public health.

This book explains transparency in biology with emphasis on bending and absorption, which together are the essence of transparency. The reader is provided with an understanding of why the interior of the body can be made to appear transparent through the application of elementary physics. Based on the principle of transparency, emerging imaging techniques using near-infrared light to view the body transparently are explained with examples such as cancer detection and temperature imaging of deep tissues. This book is useful to many researchers, including biologists, physicists, chemists, materials scientists, and device engineers as well as developers-all who seek a deep understanding of transparency in bioimaging.
