The most important lung function is to take oxygen from the environment and transfer it to the bloodstream. Lung function tests can show how well the lungs carry out this task. The left and right ...

The mitochondrial Complex I plays a central role in cellular respiration and energy metabolism. The ~1 Megadalton L-shaped protein complex is the largest protein assembly of the respiratory chain and ...

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, ...

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 ...

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 ...
