O2 Transport and Utilization in Health and Lung Disease

Skeletal muscle dysfunction is a frequent and clinically relevant systemic manifestation of Chronic Pulmonary Obstructive Disease (COPD), which is still poorly understood. Therefore, the focus of this study is on the role of a deficit in tetrahydrobiopterin and nitric oxide synthase uncoupling induced by chronic oxidative stress on metabolic and vascular abnormalities in skeletal muscle of patients suffering from COPD.
