Aeroacoustic sound alteration in airway bronchoconstriction, represented by a constricted T-branch model

Journal of Biomechanical Science and Engineering, 2015
Lung sound is commonly analyzed when testing for lung abnormalities. However, the accuracy of this analysis is low and more information on sound generation and alteration is needed to improve the analysis quality.

Macrophage TNF-α mediates parathion-induced airway hyperreactivity in guinea pigs. [PDF]

, 2013
Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that, at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs as a result of ...

Effect of exercise‐induced bronchoconstriction on the configuration of the maximal expiratory flow‐volume curve in adults with asthma

Physiological Reports, 2023
We determined the effect of exercise‐induced bronchoconstriction (EIB) on the shape of the maximal expiratory flow‐volume (MEFV) curve in asthmatic adults. The slope‐ratio index (SR) was used to quantitate the shape of the MEFV curve.
