Radioaerosol method was employed to follow up mucociliary transport (MT) efficacy in 97 patients with acute pneumonia (AP). The most pronounced suppression of MT was found in repeated and lingering AP. If causative agents were represented by adenoviruses, streptococci and influenza bacillus suppression of MT appeared more noticeable. Correlations of MT with pulmonary ventilation support the role of mucociliary insufficiency in genesis of bronchial obstruction in AP. The majority of the convalescents fail to achieve complete recovery of MT.

Objective: Radiation-induced lung injury (RILI) is a serious side-effect of radiotherapy for lung cancer, in which effects on the normal lung epithelium may play a key role. Since these effects are incompletely understood, the aim of the present study was to evaluate the effect of ionizing radiation (IR) on cultured well-differentiated primary bronchial epithelial cells (PBEC) with a focus on cytotoxicity, barrier formation, inflammation and epithelial progenitor function.
Materials And Methods: PBEC were cultured at the Air-Liquid Interface (ALI-PBEC) to allow mucociliary differentiation.
Hygrometry behavior during high-flow nasal oxygen therapy and non-invasive mechanical ventilation: A narrative review of bench to clinical studies.

Recently, there has been growing interest in knowing the best hygrometry level during high-flow nasal oxygen and non-invasive ventilation (NIV) and its potential influence on the outcome. Various studies have shown that breathing cold and dry air results in excessive water loss by nasal mucosa, reduced mucociliary clearance, increased airway resistance, reduced epithelial cell function, increased inflammation, sloughing of tracheal epithelium, and submucosal inflammation. With the Coronavirus Disease 2019 pandemic, using high-flow nasal oxygen with a heated humidifier has become an emerging form of non-invasive support among clinicians.

Aerosol delivery represents a rapid and non-invasive way to directly reach the lungs while escaping the hepatic first-pass effect. The development of pulmonary drugs for respiratory diseases such as cystic fibrosis, lung infections, pulmonary fibrosis or lung cancer requires an enhanced understanding of the relationships between the natural physiology of the respiratory system and the pathophysiology of these conditions. This knowledge is crucial to better predict and thereby control drug deposition.

The development of a inhaled nanodrug delivery assessment platform is crucial for advancing treatments for chronic lung diseases. Traditional in vitro models and commercial aerosol systems fail to accurately simulate the complex human respiratory patterns and mucosal barriers. To address this, we have developed the breathing mucociliary-on-a-chip (BMC) platform, which replicates mucociliary clearance and respiratory dynamics in vitro.

Organ-on-a-chip (OOC) devices mimic human organs, which can be used for many different applications, including drug development, environmental toxicology, disease models, and physiological assessment. Image data acquisition and analysis from these chips are crucial for advancing research in the field. In this study, we propose a label-free morphology imaging platform compatible with the small airway-on-a-chip system.
