Lipid-protein complexes reconstituted from pig surfactant lipids and proteins were investigated for surface adsorption, minimum surface tension, stability index, and surface compressibility. Lipid constituents remained unchanged with procedures for the reconstitution. An apoprote
Comparative Study of Surface-Active Properties and Antimicrobial Activities of Disaccharide Monoesters
The objective of this research was to determine the effect of sugar or fatty acid in sugar ester compounds on the surface-active properties and antimicrobial activities of these compounds. Disaccharides of medium-chain fatty acid monoesters were synthesized through transesterific
Dynamic Surface Activity of a Fully Synthetic Phospholipase-Resistant Lipid/Peptide Lung Surfactant
BACKGROUND This study examines the surface activity and resistance to phospholipase degradation of a fully-synthetic lung surfactant containing a novel diether phosphonolipid (DEPN-8) plus a 34 amino acid peptide (Mini-B) related to native surfactant protein (SP)-B. Activity stud
Pulmonary Surface Activity in Induced Pulmonary Edema.
Induction of acute pulmonary edema in anesthetized dogs causes a large fall in compliance. out of proportion to lung volume (1), and a sharp increase in venous admixture that can be reversed by forcible inflation of the lungs (2). This pattern of abnormal function suggested alveo
Surface active materials from dog lung. II. Composition and physiological correlations.
KING, RICHARD J., AND JOHN A. CLEMENTS. Surface actiue materials from dog lung. 11. Composition and physiological correlations. Am. J. Physiol. 223(3) : 715726. 1972.-We studied the chemical composition and physical properties of the four surface active materials obtained from do
Basic surface-active properties in the homologous series of β-alkyl (C12H25/C18H37) polyethyleneoxy (n = 0-20) propionamides
BACKGROUND Heterogeneous β-Alkyl (C12H25/C18H37) polyethyleneoxy (n = 0-20) propionamides [R(EO)nPD] represent new "hybrid" nonionic-ionic colloidal structures in the field of surface-active products (technical products). These "niche" compounds have three structural and composit
Surface activity of a synthetic lung surfactant containing a phospholipase-resistant phosphonolipid analog of dipalmitoyl phosphatidylcholine.
Surface activity and sensitivity to inhibition from phospholipase A2 (PLA2), lysophosphatidylcholine (LPC), and serum albumin were studied for a synthetic C16:0 diether phosphonolipid (DEPN-8) combined with 1.5% by weight of mixed hydrophobic surfactant proteins (SP)-B/C purified
Synthesis, surface-active properties, and antimicrobial activities of new double-chain gemini surfactants.
A novel series of neutral and cationic dimeric surfactants were prepared involving ketalization reaction, Williamson etherification, and regioselective oxirane ring opening with primary and tertiary alkyl amines. The critical micelle concentration (CMC), effectiveness of surface
Surface-active phospholipid as the lubricating component of lubricin.
To resolve the apparent conflict between a lubricating glycoprotein, 'lubricin', as the active ingredient in synovial fluid (SF) and surface-active phospholipid (SAPL) present in SF (and adsorbed to articular cartilage) as the boundary lubricant reducing friction to such low phys
Surface active properties of lipid nanocapsules
Lipid nanocapsules (LNCs) are biomimetic nanocarriers used for the encapsulation of a broad variety of active ingredients. Similar to surface active compounds, LNCs contain both hydrophilic and hydrophobic parts in their structure. Moreover, the components of LNCs, macrogol 15 hy
