Seasonal influences on CAPs exposures: differential responses in platelet activation, serum cytokines and xenobiotic gene expression.

abstract：:Information on nasal particle deposition is used in risk assessments for exposure to airborne particulate pollutants and for optimizing the delivery of therapeutic aerosols. Monkeys are commonly used to assess the therapeutic potential of inhaled substances and to a lesser extent the toxicity of inhaled xenobiotics. Y...

abstract：:Nano-sized particles (NSPs) have a diameter of less than 100 nm. When inhaled, they preferentially deposit in the deeper lung, where pulmonary surfactant covers the thin aqueous lining layer. Thus, pulmonary surfactant is the initial contact where NSPs impinge. This can lead to various consequences. For example, bindi...
