Application

In a study of phase transitions in cholesterol-phospholipid mixtures, cholesterol was found to be much less miscible with DSPS in the gel phase than the liquid crystal phase; up to 50 mol % cholesterol fails to abolish the hydrocarbon chain-melting phase transition.

The present study aimed to clarify the mechanism underlying the high distribution of lascufloxacin in epithelial lining fluid (ELF). Involvement of transporters was examined by transcellular transport across Calu-3 and transporter-overexpressing cells; the binding of lascufloxacin to ELF components was
