S100A14: A novel negative regulator of cancer stemness and immune evasion by inhibiting STAT3‐mediated programmed death‐ligand 1 expression in colorectal cancer

open access: yesClinical and Translational Medicine, 2022
Background Programmed death‐ligand 1 (PD‐L1) has functional roles in cancer stem‐like cell (CSC) phenotypes and chemoresistance besides immune evasion.

The tobacco-specific carcinogen-operated calcium channel promotes lung tumorigenesis via IGF2 exocytosis in lung epithelial cells

open access: yesNature Communications, 2016
The binding of tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) to nicotinic acetylcholine receptors (nAChRs) induces calcium signalling.

Basilar Predominant Emphysema: Thinking beyond Alpha-1-Antitrypsin Deficiency

open access: yesCase Reports in Medicine, 2022
Basilar predominant emphysema, or disproportionate emphysematous involvement of the lung bases compared to the apices, is an uncommon radiographic pattern of emphysema traditionally associated with alpha-1-antitrypsin deficiency (AATD). We present a case

Management of Massive Post-Tracheostomy Subcutaneous Emphysema With an Adjustable-Length, Wire-Reinforced Tracheostomy Tube: A Case Report. [PDF]

open access: yesClin Case Rep
ABSTRACT Massive subcutaneous emphysema with pneumomediastinum is a rare but potentially life‐threatening complication following tracheostomy, for which standardized management strategies are lacking. We report the case of a 67‐year‐old man who developed progressive cervicofacial and thoracic subcutaneous emphysema on postoperative Day 9 after an ...

Beyond Visual Scoring: Computational Computed Tomography Analysis for High‐Resolution Computed Tomography–Based Quantification of Interstitial Lung Disease in Inflammatory Rheumatic Disease

open access: yesArthritis Care &Research, EarlyView.
Interstitial lung disease (ILD) is a significant cause of morbidity and mortality in patients with inflammatory rheumatic disorders (IRDs). High‐resolution computed tomography (HRCT) is widely considered the gold standard for the noninvasive assessment of ILD; however, its interpretation is constrained by substantial interobserver variability and the ...

Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

open access: yesAdvanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

The impact of emphysema on surgical outcomes of early-stage lung cancer: a retrospective study

open access: yesBMC Pulmonary Medicine, 2019
Background The presence of emphysema on computed tomography (CT) is associated with an increased frequency of lung cancer, but the postoperative outcomes of patients with pulmonary emphysema are not well known.
