The composition of the pulmonary surfactant and the border conditions of normal human
breathing are relevant to characterize the interfacial behavior of pulmonary layers. Based on …

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 …

The surface behaviour of spread dipalmitoyl phosphatidyl choline (DPPC), lung surfactant
protein C (SP-C), and their mixtures were characterised using a captive bubble …

The pulmonary surfactant lines as a complex monolayer of lipids and proteins the alveolar
epithelial surface. The monolayer dynamically adapts the surface tension of this interface to …

A hydrophobic pulmonary surfactant protein, SP-C, has been implicated in surface-
associated activities thought to facilitate the work of breathing. Model surfactant films …

We have shown previously that lateral compression of pulmonary surfactant monolayers
initially induces separation of two phases but that these remix when the films become more …

The structures formed by a pulmonary surfactant model system of
dipalmitoylphosphatidylcholine (DPPC), dipalmitoylphosphatidylglycerol (DPPG), and …

Phospholipids have the major role in pulmonary surfactant concerning its biophysical
function of reducing surface tension at the alveolar air-liquid interface to facilitate respiratory …

Pulmonary surfactant is a mixture of lipids and proteins which is secreted by the epithelial
type II cells into the alveolar space. Its main function is to reduce the surface tension at the …

The studies reported here used fluorescence microscopy and Brewster angle microscopy to
test the classical model of how pulmonary surfactant forms films that are metastable at high …
