Stress amplifies lung tissue mechanics, inflammation and oxidative stress induced by chronic inflammation.

abstract：:Chronic obstructive pulmonary disease (COPD) is characterized by systemic and local chronic inflammation and oxidative stress. The sources of the increased oxidative stress in COPD patients derive from the increased burden of inhaled oxidants such as cigarette smoke and other forms of particulate or gaseous air pollut...
