In vivo endoscopic autofluorescence microspectro-imaging of bronchi and alveoli [PDF]

open access: yesDans Endoscopic Microscopy III, (Guillermo J. Tearney and Thomas D. Wang - Editors) - In vivo endoscopic autofluorescence microspectro-imaging of bronchi and alveoli, San Jose : \'Etats-Unis d'Am\'erique (2008), 2008
Fibered confocal fluorescence microscopy (FCFM) is a new technique that can be used during a bronchoscopy to analyze the nature of the human bronchial and alveolar mucosa fluorescence microstructure. An endoscopic fibered confocal fluorescence microscopy system with spectroscopic analysis capability was developed allowing real-time, simultaneous images

A biomechanical model of swallowing for understanding the influence of saliva and food bolus viscosity on flavour release [PDF]

open access: yesJournal of Theoretical Biology 280 (2011) 180-8, 2013
After swallowing a liquid or a semi-liquid food product, a thin film responsible for the dynamic profile of aroma release coats the pharyngeal mucosa. The objective of the present article was to understand and quantify physical mechanisms explaining pharyngeal mucosa coating. An elastohydrodynamic model of swallowing was developed for Newtonian liquids

Pseudomonas aeruginosa adhesion to normal and injured respiratory mucosa

open access: yesMemorias do Instituto Oswaldo Cruz, 1992
Human nasal polyps outgrowth culture were used to study the adhesion of Pseudomonas aeruginosa to respiratory cells. By transmission electron microscopy, bacteria associated with ciliated cells were identified trapped at the extremities of cilia, usually

Characteristics of the nasal mucosa of commercial pigs during normal development

open access: yesVeterinary Research, 2023
The nasal mucosa is constantly exposed to inhaled pathogens and is the first defence against respiratory infections. Here, we investigated the structural and compositional characteristics of the nasal mucosa of commercial pigs at various growth stages ...

A Fibrin Matrix Promotes the Differentiation of EMSCs Isolated from Nasal Respiratory Mucosa to Myelinating Phenotypical Schwann-Like Cells

open access: yesMolecules and Cells, 2015
Because Schwann cells perform the triple tasks of myelination, axon guidance and neurotrophin synthesis, they are candidates for cell transplantation that might cure some types of nervous-system degenerative diseases or injuries.
