Possible Interaction: Pulmonary Surfactants and Calcium Supplement

“These data indicate that SP-B and SP-C, particularly in the presence of calcium , reduce surfactant inactivation that may be caused by plasma constituents.”

“The presence of 5 mM calcium caused a significant decrease in compressibility (p < 0.05 Mann-Whitney U test) of all the surfactant monolayer films.”

“Our results support the idea that calcium ions act as a "miscibility switch" in surfactant model systems and probably are one of the major factors steering lipid/protein mixing behavior as well as influencing the protein's protrusion formation ability.”

“ Calcium (5 mM) in the subphase of LSE films altered the domain distribution, decreasing the size and increasing the number and total amount of condensed phase domains.”

“ Calcium ion is thought to play a role in the structure and function of pulmonary surfactant after secretion into the alveolar space.”

“ Ca2+ (5-10 mM) increased the onset temperature of the lipid-melting event, and induced an ordering of surfactant and of its lipid extract at all temperatures studied.”

“Study revealed hydrotrope and surfactant have synergistic effect on solubility and dissolution of atorvastatin calcium and this can be explored further.”

“This indicates that the foam stability of the surfactant less influenced by calcium ions relates to enhanced interaction configurations at the short distance.”

“This was attributed to this surfactant forming an intermolecular complex with the calcium ion at the air-water interface while the aminomalonate and the aspartate surfactants, with shorter distance between the carboxylate groups could form six- and seven-membered intramolecular calcium complexes.”

“An abrupt increase in the photocatalytic activity at a surfactant concentration of ca.”
