Transport of mucoid mucus in healthy individuals and patients with chronic obstructive pulmonary disease and bronchiectasis [PDF]

open access: yes, 2013
Objective: To characterise and compare the in vitro transport properties of respiratory mucoid secretion in individuals with no lung disease and in stable patients with chronic obstructive pulmonary disease (COPD) and bronchiectasis.Methodology: Samples ...

Airway Epithelial Differentiation and Mucociliary Clearance [PDF]

open access: yesAnnals of the American Thoracic Society, 2018
The lung is continuously exposed to particles, toxicants, and microbial pathogens that are cleared by a complex mechanical, innate, and acquired immune system. Mucociliary clearance, mediated by the actions of diverse conducting airway and submucosal gland epithelial cells, plays a critical role in a multilayered defense system by secreting fluids ...

Orbital Complications of Acute Rhinosinusitis in Adulthood: Predictors of Outcome and Management

open access: yesThe Laryngoscope, EarlyView.
In a multicenter cohort of 213 adults with orbital complications of acute rhinosinusitis, 68% required surgery and the modified Chandler classification was the strongest predictor of treatment modality. While abscess‐related and type II complications frequently necessitated surgical management, final ophthalmologic outcomes were uniformly favorable ...

Maxillary Sinus Papillary Edema as a Predictor of Odontogenic Sinusitis

open access: yesThe Laryngoscope, EarlyView.
Maxillary sinus papillary edema (MSPE) is a distinct finding that is reliably identifiable, and is significantly more likely in odontogenic sinusitis (ODS) compared to infectious chronic rhinosinusitis without nasal polyps and noninfectious chronic rhinosinusitis with nasal polyps.

Realizing the physics of motile cilia synchronization with driven colloids

open access: yes, 2015
Cilia and flagella in biological systems often show large scale cooperative behaviors such as the synchronization of their beats in "metachronal waves".

Lateral Mucosal Flap With Steroid‐Eluting Implant in Revision Draf Type III Frontal Sinus Surgery

open access: yesThe Laryngoscope, EarlyView.
This technical note introduces a novel endoscopic strategy that integrates a laterally based endonasal mucosal flap with a bioabsorbable steroid‐eluting implant to prevent restenosis following revision of Draf type III frontal sinus surgery. The vascularized flap is stabilized and maintained in close apposition to the underlying bone by a self ...

ciliaFA : a research tool for automated, high-throughput measurement of ciliary beat frequency using freely available software [PDF]

open access: yes, 2012
Background: Analysis of ciliary function for assessment of patients suspected of primary ciliary dyskinesia (PCD) and for research studies of respiratory and ependymal cilia requires assessment of both ciliary beat pattern and beat frequency.

Epigenetic Dysregulation of the NKX2‐1/SPDEF Axis Drives Persistent Goblet Cell Differentiation and Epithelial Barrier Dysfunction in Chronic Obstructive Pulmonary Disease

open access: yesRespirology, EarlyView.
This study investigated airway epithelial barrier dysfunction persistence in ex‐smokers with COPD and underlying mechanisms using single‐cell RNA and ATAC sequencing. Epigenetic NKX2‐1/SPDEF dysregulation maintains goblet cell hyperplasia and barrier dysfunction despite long‐term smoking cessation.

RBL2 represses the transcriptional activity of Multicilin to inhibit multiciliogenesis

open access: yesCell Death and Disease
A core pathophysiologic feature underlying many respiratory diseases is multiciliated cell dysfunction, leading to inadequate mucociliary clearance. Due to the prevalence and highly variable etiology of mucociliary dysfunction in respiratory diseases, it

Novel Therapeutics for Chronic Obstructive Pulmonary Disease: From Empirical Bronchodilation to Precision Medicine

open access: yesRespirology, EarlyView.
ABSTRACT Chronic obstructive pulmonary disease (COPD) remains the third leading cause of death worldwide, and conventional bronchodilator‐based therapies have limited efficacy in preventing exacerbations and disease progression. The 2024–2026 period represents a historic inflection point: three mechanistically distinct agents received Food and Drug ...
