Journal ArticleDOI
Modeling of release position and ventilation effects on olfactory aerosol drug delivery.
TL;DR: Results of this study have implications for developing new olfactory delivery devices and for optimizing delivery protocols specific to patients' ventilations, particularly with respect to pointed drug release in the vestibule and deep intubation with mediation released close to the Olfactory mucosa.
Journal ArticleDOI
Dynamic growth and deposition of hygroscopic aerosols in the nasal airway of a 5-year-old child.
TL;DR: Results of this study show that a supersaturated humid environment is possible in the nasal turbinate region and can lead to significant condensation growth (d / d(0) > 10) of nasally inhaled aerosols.
Journal ArticleDOI
Effects of mask-wearing on the inhalability and deposition of airborne SARS-CoV-2 aerosols in human upper airway
TL;DR: Investigation of the effects of wearing a surgical mask on inspiratory airflow and dosimetry of airborne, virus-laden aerosols on the face and in the respiratory tract shows that mask-wearing protects the upper airway while protecting the lungs best from particles smaller than 10 µm.
Journal ArticleDOI
Electrostatic charge effects on pharmaceutical aerosol deposition in human nasal-laryngeal airways.
TL;DR: Quantitatively evaluating the deposition of charged aerosols in an MRI-based nasal–laryngeal airway model has important implications for evaluating nasal drug delivery devices and for assessing doses received from pollutants, which often carry a certain level of electric charges.
Journal ArticleDOI
Electrophoretic Particle Guidance Significantly Enhances Olfactory Drug Delivery: A Feasibility Study
TL;DR: A high sensitivity of olfactory dosage was observed in relation to different pointed release positions, indicating the importance of precise particle guidance for effective olfFactory delivery.
