The association of chest computed tomography-defined visual emphysema and prognosis in patients with nonsmall cell lung cancer

open access: yesERJ Open Research, 2023
Background Although computed tomography (CT)-defined emphysema is considered a predictor of lung cancer risk, it is not fully clear whether CT-defined emphysema is associated with the prognosis of lung cancer. We aimed to assess the clinical impact of CT-

Functional Pulmonary Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The aging of the world population gave rise to an increased prevalence of many lung diseases, with chronic obstructive pulmonary disease now ranking as the third‐leading cause of death according to the World Health Organization. To diagnose lung disease, a thorough assessment of lung function is essential since it may reveal unique signatures ...

Three new Alpha1-Antitrypsin deficiency variants help to define a C-Terminal region regulating conformational change and polymerization [PDF]

open access: yes, 2012
Alpha1-antitrypsin (AAT) deficiency is a hereditary disorder associated with reduced AAT plasma levels, predisposing adults to pulmonary emphysema.

Basophils trigger emphysema development in a murine model of COPD through IL-4–mediated generation of MMP-12–producing macrophages

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Chronic obstructive pulmonary disease has generally been considered a non-Th2-type lung disease, in contrast to allergic asthma. We identified unexpected roles for basophils, Th2 cytokine IL-4, and interstitial macrophages in triggering ...

Magnetic Resonance Imaging in the Clinical Evaluation of Lung Disorders: Current Status and Future Prospects

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The low proton density and high signal decay rate of pulmonary tissue have previously hampered the application of magnetic resonance imaging (MRI) in the clinical evaluation of lung disorders. With the continuing technical advances in scanners, coils, pulse sequences, and image postprocessing, pulmonary MRI can provide structural and ...

Roles of mitochondrial ROS and NLRP3 inflammasome in multiple ozone-induced lung inflammation and emphysema

open access: yesRespiratory Research, 2018
BackgroundMitochondrial damage leading to oxidant stress may play an important role in the pathogenesis of airflow obstruction and emphysema. NLPR3 inflammasome can be activated by mitochondrial ROS (mtROS) and other stimuli.

Lung volumes identify an at-risk group in persons with prolonged secondhand tobacco smoke exposure but without overt airflow obstruction. [PDF]

open access: yes, 2018
IntroductionExposure to secondhand smoke (SHS) is associated with occult obstructive lung disease as evident by abnormal airflow indices representing small airway disease despite having preserved spirometry (normal forced expiratory volume in 1 s-to ...
