The respiratory system is responsible for the exchange of carbon dioxide and oxygen in the human body. This system also helps remove metabolic waste products and keep pH levels in check. The major ...

High levels of phenotypic age acceleration (PhenoAgeAccel) were found to have a more significant effect on lung function in patients with chronic obstructive pulmonary disease (COPD), older patients, ...

Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...

Instead, surfactant is also important in narrow tubular respiratory structures such as the terminal airways of mammals and the air capillaries of birds. (3). Insect tracheoles: We investigate the ...

The functions of biomolecules, including lipids, nucleic acids and especially proteins are determined to a great extent by their structure. This structure–function relationship is a foundation of many ...

Background: In air pollution time-series studies, the temporal pattern of the association of fine particulate matter (PM₂.₄; particulate matter < 2.5 µm in aerodynamic diameter) and health end points ...
