Xylem surfactants introduce a new element to the cohesion-tension theory [PDF]

open access: yes, 2016
Vascular plants transport water under negative pressure without constantly creating gas bubbles that would disable their hydraulic systems. Attempts to replicate this feat in artificial systems almost invariably result in bubble formation, except under ...

Insights Gained Into the Treatment of COVID19 by Pulmonary Surfactant and Its Components

open access: yesFrontiers in Immunology, 2022

The role of surface charge in the interaction of nanoparticles with model pulmonary surfactants [PDF]

open access: yes, 2018
Inhaled nanoparticles traveling through the airways are able to reach the respiratory zone of the lungs. In such event, the incoming particles first enter in contact with the liquid lining the alveolar epithelium, the pulmonary surfactant.

Effects of Exogenous Surfactants on the Parameters of Blood Gas Composition in Neonatal Respiratory Distress Syndrome

open access: yesОбщая реаниматология, 2007
Objective: to study the effects of the surfactants Surfactant-BL and Curosurf on pulmonary oxygenizing properties in preterm neonatal infants with respiratory distress syndrome (RDS). The studies were performed in 81 preterm neonates with severe RDS. For

Pulmonary surfactant

open access: yesJournal of Applied Physiology, 1982
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.

Altered surfactant homeostasis and recurrent respiratory failure secondary to TTF-1 nuclear targeting defect

open access: yesRespiratory Research, 2011
Background Mutations of genes affecting surfactant homeostasis, such as SFTPB, SFTPC and ABCA3, lead to diffuse lung disease in neonates and children. Haploinsufficiency of NKX2.1, the gene encoding the thyroid transcription factor-1 (TTF-1) - critical ...

Local lung hypoxia determines epithelial fate decisions during alveolar regeneration. [PDF]

open access: yes, 2017
After influenza infection, lineage-negative epithelial progenitors (LNEPs) exhibit a binary response to reconstitute epithelial barriers: activating a Notch-dependent ΔNp63/cytokeratin 5 (Krt5) remodelling program or differentiating into alveolar type II

Surfactant spreading on liquid films in the Stokes regime

open access: yesAIP Advances, 2022
Characterizing the spreading of surfactants on the surface of a liquid film is central to our understanding of natural and technological processes ranging from cell propulsion and drug delivery in pulmonary airways to cleaning food processing surfaces ...

Pulmonary Surfactant and Drug Delivery: An Interface-Assisted Carrier to Deliver Surfactant Protein SP-D Into the Airways

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
This work is focused on the potential use of pulmonary surfactant to deliver full-length recombinant human surfactant protein SP-D (rhSP-D) using the respiratory air-liquid interface as a shuttle.
