Correlations between bulk and surface properties of meibomian lipids with alteration of wax- to-sterol esters content

These are the surface pressure/area isotherms and the stress relaxations of the transient dilatational elasticity modulus used in the study "Correlations between bulk and surface properties of meibomian lipids with alteration of wax- to-sterol esters content" in Chemistry and Physics of Lipids https://www.sciencedirect.com/science/article/pii/S000930842100116X

The measurements are performed with by Langmuir surface balance µ Trough XS, area 135 cm², volume 100 mL (Kibron, Helsinki, Finland), via the Wilhelmy wire probe method (instrumental accuracy 0.01 mN/m). Physiological saline solution buffer (PBS, pH 7.4) was utilized as trough subphase.
