Analysis of Pulsatile Vessel Expansion in Healthy, COPD‐and PH‐Patients Using Dynamic Vessel Segmentation in Free‐Breathing Lung MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The pulsatile expansion of pulmonary vessels carries dynamic cardiopulmonary information that may reveal disease earlier than structural changes alone. Purpose To test (i) intra‐ and inter‐scan repeatability of dynamic vessel metrics in healthy subjects, and (ii) whether chronic obstructive pulmonary disease (COPD) and postcapillary

Pathophysiology, clinical manifestation, and treatment of tuberculosis-associated chronic obstructive pulmonary disease: a narrative review [PDF]

The Ewha Medical Journal
Chronic obstructive pulmonary disease (COPD) is a leading cause of respiratory morbidity and mortality, most often linked to smoking. However, growing evidence indicates that previous tuberculosis (TB) infection is also a critical risk factor for COPD ...

Oxymatrine Inhibits Epithelial‐Mesenchymal Transition to Alleviate Airway Remodeling in Chronic Obstructive Pulmonary Disease by Suppressing the TGF‐β1/Smad Pathway

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study explored the therapeutic efficacy of oxymatrine (OMT, C15H24N2O2) in a murine model of cigarette smoke (CS)‐induced chronic obstructive pulmonary disease (COPD) and elucidated its underlying mechanisms. A COPD model was established in mice through prolonged exposure to CS, followed by intraperitoneal administration of OMT (50 mg/kg)

Potential Biomarkers for Disease Stratification and Prognosis Prediction in Pediatric Asthma: LCN2, sST2 and FGF21

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Pediatric asthma is a common chronic airway inflammatory disease, where accurate assessment of disease severity and prognosis prediction is crucial for treatment decisions. Currently, there is a lack of precise and effective biomarkers.

Recent Progress in Treating Airway Mucus Hypersecretion by Targeting the Epidermal Growth Factor Receptor Signaling Pathway

Pediatric Discovery, EarlyView.
ABSTRACT Asthma, chronic pulmonary obstructive disease (COPD), cystic fibrosis, and acute respiratory infections are severe respiratory conditions that significantly contribute to global morbidity and mortality. Airway mucus hypersecretion is an important common pathophysiological and clinical manifestation of these diseases and is closely associated ...

The Nasal Microbiome and Associations With Environmental Exposures and Respiratory Health

Allergy, EarlyView.
This study evaluates the association of the nasal microbiome with air pollutants, meteorological conditions, and respiratory health in adolescents. Bacterial diversity is positively associated with hay fever and short‐term NO2 exposure, and negatively with temperature. A Moraxella‐dominated nasotype is linked to lower O3 exposure and higher temperature

BRONCHIAL RESPONSE TIME TO A BRONCHODILATING AGENT-ORCIPRENALINE

The Keio Journal of Medicine, 1973
The specific airway conductance (Gaw/Vtg) of 4 normal subjects and 5 subjects with respiratory diseases was measured before and after inhalation of orciprenaline. There was an almost maximum increase in Gaw/Vtg within 3 to 4 minutes in both groups of subjects after inhalation of orciprenaline.

Wildfires and Atopic Diseases: A Review

Allergy, EarlyView.
ABSTRACT Wildfire smoke is a major environmental health threat that has increased in frequency and severity in recent years. A hazardous component of wildfire smoke is particulate matter ≤ 2.5 μm (PM2.5). There is evidence to suggest that exposure to wildfire PM2.5 may increase the risk of developing or exacerbating atopic diseases, such as asthma ...
