Amidst the rising prevalence of respiratory diseases, the importance of effective lung treatment modalities is more critical than ever. However, current drug delivery systems face significant limitations that impede their efficacy and therapeutic outcome. Biohybrid microrobots have shown considerable promise for active in vivo drug delivery, especially for pulmonary applications via intratracheal routes.

A simple LC method has been developed and validated for estimating budesonide (epimer B + A) and formoterol fumarate dihydrate in dry powder inhalation. The development results of this study make it very significant. The degradation and process impurities in EP and ChP were identified in addition to budesonide and formoterol fumarate.

Identification of lesion demarcation during thoracoscopic anatomical lesion resection is fundamental for treating children with congenital lung malformation. Existing lesion demarcations do not always meet the needs of clinical practice. This study aimed to explore the safety and efficacy of near-infrared fluorescence imaging with nebulized inhalation of indocyanine green for thoracoscopic anatomical lesion resection in children with congenital lung malformation.

Despite the success in COVID-19 mRNA vaccines, direct local delivery of mRNA into the lung by inhalation would greatly reinforce the treatment of pulmonary pathogens and diseases. Herein, we developed lipid nanoparticles (LNPs) from degradable ionizable glycerolipids for potent pulmonary mRNA delivery via nebulization.

Background Pulmonary function tests are central to diagnosis and monitoring of respiratory diseases but do not provide information on regional lung function heterogeneity. Fluorine 19 (F) MRI of inhaled perfluoropropane permits quantitative and spatially localized assessment of pulmonary ventilation properties without tracer gas hyperpolarization. Purpose To assess regional lung ventilation properties using F MRI of inhaled perfluoropropane in participants with asthma, participants with chronic obstructive pulmonary disease (COPD), and healthy participants, including quantitative evaluation of bronchodilator response in participants with respiratory disease.
