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.

Influence of lung physical properties on its flow--volume curves using a detailed multi-scale mathematical model of the lung [PDF]
arXiv, 2022 We develop a mathematical model of the lung that can estimate independently the air flows and pressures in the upper bronchi. It accounts for the lung multi-scale properties and for the air-tissue interactions. The model equations are solved using the Discrete Fourier Transform, which allows quasi instantaneous solving, in the limit of the model ...

CDFI: Cross Domain Feature Interaction for Robust Bronchi Lumen Detection [PDF]
arXiv, 2023 Endobronchial intervention is increasingly used as a minimally invasive means for the treatment of pulmonary diseases. In order to reduce the difficulty of manipulation in complex airway networks, robust lumen detection is essential for intraoperative guidance.

Automated airway segmentation by learning graphical structure [PDF]
arXiv, 2021 In this research project, we put forward an advanced method for airway segmentation based on the existent convolutional neural network (CNN) and graph neural network (GNN). The method is originated from the vessel segmentation, but we ameliorate it and enable the novel model to perform better for datasets from computed tomography (CT) scans.

The role of circular RNAs in regulating cytokine signaling in cancer
FEBS Open Bio, EarlyView.Cytokines present in the tumor microenvironment fuel cancer development. Aberrant expression of circRNAs contributes to cancer progression. Cytokines are involved in regulating circRNA biogenesis. Furthermore, aberrantly expressed circRNAs regulate the expression of ligands, receptors, and downstream effectors involved in cytokine signaling to promote ...

Case report : Williams-Campbell syndrome [PDF]
, 2009 Background: Williams-Campbell syndrome is a rare type of bronchiectasis that is due to deficiency or absence of cartilage in the fourth- to sixth-order bronchi.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Current radiotherapy practices rely on manual contouring of CT scans, which is time‐consuming, prone to variability, and requires highly trained experts. There is a need for more efficient and consistent contouring methods. This study evaluated the performance of the Varian Ethos AI auto‐contouring tool to assess its potential integration into
