Inhalation of ultrafine and fine particulate matter disrupts systemic vascular function.

abstract：OBJECTIVES:Rodents used in scientific research are typically housed in cages containing natural bedding materials. Despite extensive evidence of biological harm from inhaled particulate matter (PM), relatively little work has been performed to measure bedding-generated PM exposure in caged animals used in basic science...
