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

, 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 ...

Novel opportunities from bioimaging to understand the trafficking and maturation of intracellular pulmonary surfactant and its role in lung diseases

Frontiers in Immunology, 2023
Pulmonary surfactant (PS), a complex mixture of lipids and proteins, is essential for maintaining proper lung function. It reduces surface tension in the alveoli, preventing collapse during expiration and facilitating re-expansion during inspiration ...

Invariant Natural Killer T Cells Play a Role in Chemotaxis, Complement Activation and Mucus Production in a Mouse Model of Airway Hyperreactivity and Inflammation. [PDF]

PLoS ONE, 2015
CD1d-restricted invariant natural killer T (iNKT) cells play a critical role in the induction of airway hyperreactivity (AHR). After intranasal alpha-galactosylceramide (α-GalCer) administration, bronchoalveolar lavage fluid (BALF) proteins from mouse ...

Surfactant function in neonates with respiratory distress syndrome [PDF]

, 1998
The function of pulmonary surfactant of a group of 14 preterm neonates (birth weight 907 +/- 60 g) who suffered from severe respiratory distress syndrome (RDS) and who had received exogenous bovine lipid extracted surfactant on the first day of life was ...

Pulmonary surfactant coating of multi-walled carbon nanotubes (MWCNTs) influences their oxidative and pro-inflammatory potential in vitro

Particle and Fibre Toxicology, 2012
Background Increasing concern has been expressed regarding the potential adverse health effects that may be associated with human exposure to inhaled multi-walled carbon nanotubes (MWCNTs). Thus it is imperative that an understanding as to the underlying

Immature Circulating SP-B, Bound to HDL, Represents an Early Sign of Smoke-Induced Pathophysiological Alterations

Biomolecules, 2021
Cigarette smoking is a major independent risk factor for cardiovascular diseases (CVD). The underlying mechanisms, however, are not clearly understood. Lungs are the primary route of exposure to smoke, with pulmonary cells and surfactant being the first ...

Is There More to This Case than Mere Pulmonary Alveolar Proteinosis? A Clinical Case Presentation

European Journal of Case Reports in Internal Medicine, 2015
Introduction: Pulmonary alveolar proteinosis (PAP) is a rare disease, associated with excess accumulation of surfactant proteins and lipids in the alveoli.

The interplay of lung surfactant proteins and lipids assimilates the macrophage clearance of nanoparticles. [PDF]

PLoS ONE, 2012
The peripheral lungs are a potential entrance portal for nanoparticles into the human body due to their large surface area. The fact that nanoparticles can be deposited in the alveolar region of the lungs is of interest for pulmonary drug delivery ...
