How easy it is to dismiss the humdrum surfactant! After all, its structure is unglamorous by present-day norms. And the surfactant has been entrenched in so many areas of commerce for so many decades that its chemistry might seem old and tired. The purpose of this review is to persuade the reader otherwise, all the while focusing on a remarkable new ...

Synfacts, 2006
Many industrial applications that rely on emulsions would benefit from an efficient, rapid method of breaking these emulsions at a specific desired stage. We report that long-chain alkyl amidine compounds can be reversibly transformed into charged surfactants by exposure to an atmosphere of carbon dioxide, thereby stabilizing water/alkane emulsions or,

Based on these metabolic studies of surfactant lipids in term lambs, in preterm lambs not treated with surfactant, and in preterm lambs that have been surfactant-treated, the following is a synthesis of the overall metabolism of surfactant. Preterm surfactant-deficient lungs seem to have all the synthetic and secretory pathways for surfactant ...

Current Opinion in Pediatrics, 2007
To present existing data on the potential use of aerosolized surfactants for treatment of neonatal respiratory distress syndrome in the era of noninvasive ventilatory support.Current surfactant therapy requires endotracheal intubation and application of positive pressure ventilation.

Annual Review of Medicine, 1989
Pulmonary surfactant is a chemically heterogeneous material that provides a stable, low surface tension within the lung, thereby preventing alveolar collapse at low transpulmonary pressures. Both the lipid and the protein components of surfactant are important for establishing and maintaining a low surface tension.

Resuscitation, 1989
This paper presents the rationale for surfactant replacement therapy. In 6 animal models in which respiratory failure was induced by damaging the bronchial surfactant, surfactant depletion by lung lavage, by free oxygen radicals, by influenza virus and by anti-lung serum, it is demonstrated that surfactant instillation always led to an improvement in ...

Biotechnology Advances, 1985
Interest in microbially produced biosurfactants has increased recently, due mainly to their potential as agents in enhanced oil recovery. A variety of microbes and their products have been assessed for their surface-active properties, and it has been suggested that biosurfactants may prove useful in a broad spectrum of potential applications which ...

Coacervation with surfactants: From single-chain surfactants to gemini surfactants
Advances in Colloid and Interface Science, 2017Coacervation is a spontaneous process during which a colloidal dispersion separates into two immiscible liquid phases: a colloid-rich liquid phase in equilibrium with a diluted phase. Coacervation is usually divided into simple coacervation and complex coacervation according to the number of components.

Pulmonary surfactant reduces the surface tension of the alveolar air-liquid interface, thereby providing mechanical stability and preventing alveolar atelectasis. More than 50% of surfactant is dipalmitoyl phosphatidylcholine, a material that is capable of reducing the surface tension of the alveolar interface to uniquely low values.

Neonatal Surfactant Deficiency and Surfactant Replacement Therapy
International Journal of Technology Assessment in Health Care, 1991For the past 25 years, attempts have been made to treat respiratory distress syndrome (RDS) by administration of surfactant into the airways. This practice is not yet an accepted form of therapy. Lack of generally available surfactant during the present era of prospective studies will hopefully decrease the therapeutic misuse of this novel medicine.
