Pulmonary surfactant functions by first flowing rapidly into the alveolar air/water interface, but
then resisting collapse from the surface when the adsorbed interfacial film is compressed …

Pulmonary surfactant lowers surface tension in the lungs. Physiological studies indicate two
key aspects of this function: that the surfactant film forms rapidly; and that when compressed …

This review briefly notes recent findings important for understanding the surface mechanical
functions of pulmonary surfactant. Currently known surfactant-specific proteins and lipids are …

Pulmonary surfactant is a lipid-protein complex which has the essential physiological role of
stabilizing the respiratory surface of lungs against collapse. To achieve this function …

The structural and functional alterations in pulmonary surfactant that occur during acute lung
injury were studied using rat lung surfactant large aggregates (LA) isolated from normal …

Pulmonary surfactant spreads on the thin (∼ 0.1μm) liquid layer that lines the alveoli,
forming a film that reduces surface tension and allows normal respiration. Pulmonary …

To determine if lateral phase separation occurs in films of pulmonary surfactant, we used
epifluorescence microscopy and Brewster angle microscopy (BAM) to study spread films of …

Pulmonary surfactant is a critical component of lung function in healthy individuals. It
functions in part by lowering surface tension in the alveoli, thereby allowing for breathing …

Pulmonary surfactant maintains a putative surface-active film at the air-alveolar fluid
interface and prevents lung collapse at low volumes. Porcine lung surfactant extracts (LSE) …

Survanta, a clinically used bovine lung surfactant extract, in contact with surfactant in the
subphase, shows a coexistence of discrete monolayer islands of solid phase coexisting with …
