Significats de pulmonary surfactant en anglès

Secretion of pulmonary surfactant in the alveoli of the lungs is essential to maintain lung function.

Mixtures of PxB and pulmonary surfactant show antimicrobial effects in neonatal rabbits and prevent systemic spreading of E. coli.

In neonatal pneumonia, the surface activity of pulmonary surfactant is impaired and microorganisms may invade by passing the air-liquid interface.

Recent studies have demonstrated that pulmonary surfactant protein (SP)-A plays a potential role in modifying inflammation and immune function.

However, it is vital that corticosteroids delivered via the lungs not interfere with surface activity of the pulmonary surfactant lining layer.

This study has implications in the fundamental understanding of surface thermodynamics as well as applications such as self-assembled monolayers and pulmonary surfactant biophysics.

We demonstrated that the increased absorption resulted from DPPC that had permeation enhancer properties even though it was abundantly present locally in pulmonary surfactant.

The acute respiratory distress syndrome (ARDS) is characterized by arterial hypoxemia accompanied by severe inflammation and alterations to the pulmonary surfactant system.

Inhaled NP penetrate deep pulmonary structures in which they first interact with the pulmonary surfactant (PS) lining at the alveolar air-water interface.

Objective: Our goal was to examine the effects of oligohydramnios and cervical cord transection on fetal lung development, pulmonary surfactant, and lung mechanics in rabbits.

Hydrophobic protein of 6,000 and 14,000 daltons was isolated from mammalian pulmonary surfactant obtained from canine, human, and bovine alveolar lavage material.

Pulmonary surfactant acts at this air-liquid interface.

Pulmonary surfactant dysfunction may significantly contribute to small airway obstruction during the asthmatic response, but neither its exact role nor its regulation is clear.

It has been reported that pulmonary surfactants or their components could facilitate the uptake of small interfering RNA (siRNA) into the lung epithelial cells.

Pulmonary surfactant (PS) dysfunction because of the leakage of serum proteins into the alveolar space could be an operative pathogenesis in acute respiratory distress syndrome.
