Progressive pulmonary tuberculosis associated with bronchial dilatation: A clinical image

open access: yesClinical Case Reports, 2022
Bronchial dilatation is a potentially serious and irreversible clinical and radiological entity. It is an often underdiagnosed condition, particularly in developing countries.

Bronchoabsorption; a novel bronchoscopic technique to improve biomarker sampling of the airway [PDF]

open access: yes, 2015
BACKGROUND: Current techniques used to obtain lung samples have significant limitations and do not provide reproducible biomarkers of inflammation. We have developed a novel technique that allows multiple sampling methods from the same area (or multiple ...

Contralaterally Enhanced Networks for Thoracic Disease Detection [PDF]

open access: yesarXiv, 2020
Identifying and locating diseases in chest X-rays are very challenging, due to the low visual contrast between normal and abnormal regions, and distortions caused by other overlapping tissues. An interesting phenomenon is that there exist many similar structures in the left and right parts of the chest, such as ribs, lung fields and bronchial tubes ...

Protective effect of leukotriene receptor antagonist montelukast on smoking-induced lung injury in Wistar rats. [PDF]

open access: yes, 2003
Increased activation of alveolar macrophage, neutrophil and mast cell has been proven in cigarette smoking (CS)-related lung disorders (CSLD). An increased production of cysteinyl-leukotrienes (LTs), which are mediators secreted from the mentioned cells,

Combination therapy for cough and bronchial obstruction in childhood

open access: yesМедицинский совет, 2019
The inflammatory process in the bronchial mucosa of various origins (infectious, allergic, irritative, etc.) cause changes in the sputum production and its rheological properties, slowing of mucociliary clearance.

Navigation Through Endoluminal Channels Using Q-Learning [PDF]

open access: yesarXiv, 2023
In this paper, we present a novel approach to navigating endoluminal channels, specifically within the bronchial tubes, using Q-learning, a reinforcement learning algorithm. The proposed method involves training a Q-learning agent to navigate a simulated environment resembling bronchial tubes, with the ultimate goal of enabling the navigation of real ...

Scale dependence of branching in arterial and bronchial trees [PDF]

open access: yesPhysical Review Letters v 96, 128101 (2006), 2005
Although models of branching in arterial and bronchial trees often predict a dependence of bifurcation parameters on the scale of the bifurcating vessels, direct verifications of this dependence with data are uncommon. We compare measurements of bifurcation parameters in airways and arterial trees of different mammals as a function of scale to general ...

Diagnosis and management of eosinophilic asthma: a US perspective. [PDF]

open access: yes, 2014
Eosinophilic asthma is now recognized as an important subphenotype of asthma based on the pattern of inflammatory cellular infiltrate in the airway. Eosinophilic asthma can be associated with increased asthma severity, atopy, late-onset disease, and ...

Cellular burdens and biological effects on tissue level caused by inhaled radon progenies [PDF]

open access: yesRadiation Protection Dosimetry 143 (2011): 253-57, 2014
In the case of radon exposure, the spatial distribution of deposited radioactive particles is highly inhomogeneous in the central airways. The objective of this research is to investigate the consequences of this heterogeneity regarding cellular burdens in the bronchial epithelium and to study the possible biological effects on tissue level. Applying a
