Histological and anatomical structure of the nasal cavity of Bama minipigs. [PDF]
PLoS ONE, 2017 OBJECTIVE:The nasal mucosa is equipped with abundant lymphatic tissues, serving as the first line of defense against invasion by microorganisms. In this study, we characterized the features of the nasal mucosa of Bama minipigs (Sus scrofa domestica) via ...

Investigation on the nasal airflow characteristics of anterior nasal cavity stenosis
Brazilian Journal of Medical and Biological Research, 2016 We used a computational fluid dynamics (CFD) model to study the inspiratory airflow profiles of patients with anterior nasal cavity stenosis who underwent curative surgery, by comparing pre- and postoperative airflow characteristics. Twenty patients with

Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2017 The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals.

The nasal cavity microbiota of healthy adults [PDF]
Microbiome, 2014 Background The microbiota of the nares has been widely studied. However, relatively few studies have investigated the microbiota of the nasal cavity posterior to the nares. This distinct environment has the potential to contain a distinct

Influence of Latent Heat in the Nasal Cavity
Journal of Biomechanical Science and Engineering, 2013 Among the several functions of the nasal cavity, temperature and humidity adjustments are important for preserving the trachea and lungs. The functions of the nasal cavity have been clarified in experiments investigating the conditions in the nasal ...

Factors influencing drug deposition in the nasal cavity upon delivery via nasal sprays
Journal of Pharmaceutical Investigation, 2020 Background In nasal drug delivery system, nasal spray seems to be the most promising delivery method for both local and systemic diseases therapy. Nasal deposition behavior is the most basic and important process for nasal sprays, which is related to ...

Friend or Foe: Interbacterial Competition in the Nasal Cavity
Journal of Bacteriology, 2020 Like other microbes that live on or in the human body, the bacteria that inhabit the upper respiratory tract, in particular the nasal cavity, have evolved to survive in an environment that presents a number of physical and chemical challenges; these ...
