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.

Medical Hypotheses, 1977
In previous publications (1,2) the hypothesis was put forward that atheroma is caused by some pathogen or metabolic fault which impairs the transportability of cholesterol in the plasma. The lipoproteins containing the faulty metabolites are assumed to be incapable of traversing the capillary endothelium and continue to circulate uselessly in the blood

International Journal of Cosmetic Science, 1998
The skin surface is the interface between us, the organism, and the outside world. When we clean the skin we remove not only the bacteria, dirt and grease which have accumulated, but also part of our natural barrier ‐ the stratum corneum. Corneocytes, both singly and in clumps, are released from the skin surface by the action of detergents and ...

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,

Clinics in Perinatology, 1993
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.

Emergency Medicine Clinics of North America, 2008
In this article, the physiology of surfactant is reviewed along with the research that lead to its current clinical uses. Acute lung injury (ALI) and Acute Respiratory Distress Syndrome (ARDS) will also be reviewed because they represent pulmonary disease processes in which secondary deficiency and surfactant inactivation occur, for which surfactant ...

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.

Surfactants and the environment
International Journal of Cosmetic Science, 1984SynopsisAs a result of their use in detergents and personal products and their subsequent disposal, anionic surfactants may achieve a wide distribution in the environment. It is therefore important to assess the hazard that this use might present to the environment.In order to do this it is necessary to estimate the highest concentrations which are ...
