Spirometry is the current gold standard for diagnosing and monitoring the progression of
Chronic Obstructive Pulmonary Disease (COPD). However, many current and former …

Chest CT is often used for localizing and quantitating pathologies associated with chronic
obstructive pulmonary disease (COPD). While simple measurements of areas and volumes …

The colonization of surfaces by bacteria is a widespread phenomenon with consequences
on environmental processes and human health. While much is known about the molecular …

Chronic obstructive pulmonary disease (COPD) is associated with morphologic
abnormalities of airways with various patterns and severities. However, the way of effectively …

The computed tomography (CT) chest is a tool for diagnostic tests and the early evaluation
of lung infections, pulmonary interstitial damage, and complications caused by common …

In this study, we investigate the steady inhalation, steady exhalation, and oscillatory flow in a
realistic airway geometry for physiologically relevant regimes ranging from quiet breathing to …

Particle transport in lung airways can induce respiratory disease and play a vital role in
aerosol drug delivery. Herein, we present dynamical systems features that influence airflow …

Early COPD is an important manifestation of COPD, with a newly proposed definition and
associated risk factors identified. Inferring from studies on mild COPD cohorts, LAMAs and …

Purpose To develop a novel method for calculating small airway resistance using
computational fluid dynamics (CFD) based on CT data and evaluate its value to identify …

Introduction Cathelicidin (also known as LL-37 in humans) is an antimicrobial peptide
