Expression and function of human hemokinin-1 in human and guinea pig airways [PDF]
Respiratory Research, 2010 Background Human hemokinin-1 (hHK-1) and endokinins are peptides of the tachykinin family encoded by the TAC4 gene. TAC4 and hHK-1 expression as well as effects of hHK-1 in the lung and airways remain however unknown and were explored in this study ...

Break: Bronchi Reconstruction by Geodesic Transformation and Skeleton Embedding [PDF]
IEEE International Symposium on Biomedical Imaging, 2022 Airway segmentation is critical for virtual bronchoscopy and computer-aided pulmonary disease analysis. In recent years, convolutional neural networks (CNNs) have been widely used to delineate the bronchial tree.

Inhaled aerosol dose distribution between proximal bronchi and lung periphery.
European journal of pharmaceutics and biopharmaceutics, 2020 Modern inhaled drug discovery programs assess dose delivery to proximal and distal airways using rudimentary imaging indices, where relative deposition is estimated by generically defined 'central' and 'peripheral' lung regions.

Effect of variations in atelectasis on tumor displacement during radiation therapy for locally advanced lung cancer [PDF]
, 2017 Purpose Atelectasis (AT), or collapsed lung, is frequently associated with central lung tumors. We investigated the variation of atelectasis volumes during radiation therapy and analyzed the effect of AT volume changes on the reproducibility of the ...

Characterizing the viscoelasticity of extra- and intra-parenchymal lung bronchi.
Journal of The Mechanical Behavior of Biomedical Materials, 2020 Pulmonary disease is known to cause remodeling of tissue structure, resulting in altered viscoelastic properties; yet the foundation for understanding this phenomenon is still nascent and will enable scientific insights regarding lung functionality.

Stenosis of the right major bronchus from blunt trauma [PDF]
Vojnosanitetski Pregled, 2006 Background. A severe blunt injury to the chest might cause rupture of the tracheobronchial tree. A certain time following the management of the injury, stenosis of the bronchi may develop at the site of the rupture. Case report.

Imaging diagnosis-computed tomography of traction bronchiectasis secondary to pulmonary fibrosis in a Patterdale Terrier [PDF]
, 2016 An 8-year-old, Patterdale terrier was referred for evaluation of tachypnoea, exercise intolerance, and weight loss. Computed tomographic images showed pneumomediastinum, diffuse pulmonary ground glass opacity, and marked dilatation of peripheral bronchi,
