Oxidative stress is a major driving mechanism in the pathogenesis of COPD. There is
increased oxidative stress in the lungs of COPD patients due to exogenous oxidants in …

Background: Limb muscle dysfunction is prevalent in chronic obstructive pulmonary disease
(COPD) and it has important clinical implications, such as reduced exercise tolerance …

Purpose. Leukocyte telomere length (LTL) is an important biomarker of aging. The oxidative
balance score (OBS) is used to assess the oxidative stress‐related exposures of diet and …

Oxygen‐free radicals, reactive oxygen species (ROS) or reactive nitrogen species (RNS),
are known by their “double‐sided” nature in biological systems. The beneficial effects of …

Oxidative stress is now recognized as a major predisposing factor in the pathogenesis of
COPD. Existing therapies for COPD are ineffective at halting disease progression, with …

Ferroptosis is a type of cell death related to cancer; however, the characteristics of
ferroptosis in cancers are still uncertain. Based on the data in The Cancer Genome Atlas, we …

Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow
limitation and loss of lung function, and is currently the third largest cause of death in the …

Quadriceps weakness is an important complication of advanced chronic obstructive
pulmonary disease (COPD) but few data exist concerning muscle bulk in early disease. We …

Respiratory and/or limb muscle dysfunction, which are frequently observed in chronic
obstructive pulmonary disease (COPD) patients, contribute to their disease prognosis …

Airways are exposed to myriad environmental and damaging agents such as reactive
oxygen species (ROS), which also have physiological roles as signaling molecules that …
