The prevalence of gas exchange data processing methods: a semi-automated scoping review.

Cardiopulmonary exercise testing involves collecting variable breath-by-breath data, sometimes requiring data processing of outlier removal, interpolation, and averaging before later analysis. These data processing choices, such as averaging duration, affect calculated values such as VOmax. However, assessing the implications of data processing without knowing popular methods worth comparing is difficult.

Redox Signaling and Sarcopenia: Searching for the Primary Suspect.

Sarcopenia, the age-related decline in muscle mass and function, derives from multiple etiological mechanisms. Accumulative research suggests that reactive oxygen species (ROS) generation plays a critical role in the development of this pathophysiological disorder. In this communication, we review the various signaling pathways that control muscle metabolic and functional integrity such as protein turnover, cell death and regeneration, inflammation, organismic damage, and metabolic functions.
