Abstract Background Peripheral muscle weakness can be caused by both peripheral muscle and neural alterations. Although peripheral alterations cannot totally explain peripheral muscle weakness in COPD, the existence of an activation deficit remains c

The O2 reactivity of flavoproteins and particularly, glucose oxidase, is a limitation for numerous biotechnological applications, and this has been the subject of intense research. In the present study, we performed site-directed mutations on Val464

Many studies report cognitive dysfunction in COPD. This could have a major impact on daily life activities and more specifically on complex tasks. To date, only one study has evaluated the impact of this dysfunction in dual task (DT) (Karakontaki, F.

Introduction Brain impairment is a major extrapulmonary effect of COPD and is involved in locomotor muscle weakness by reducing cortical motor output. Cerebrovascular O 2 reactivity (i.e. an increase in cerebral blood flow) protects the brain against

The superoxide radical O 2 ·̅ is a toxic by-product of oxygen metabolism. Two O 2 ·̅ detoxifying enzymes have been described so far, superoxide dismutase and superoxide reductase (SOR), both forming H 2 O 2 as a reaction product. Recently, the SO
