A Systematic Review of the Variability of Ventilation Defect Percent Generated From Hyperpolarized Noble Gas Pulmonary Magnetic Resonance Imaging

Journal of Magnetic Resonance Imaging, Volume 62, Issue 3, Page 625-639, September 2025.
ABSTRACT Hyperpolarized (HP) gas pulmonary MR ventilation images are typically quantified using ventilation defect percent (VDP); however, the test‐retest variability of VDP has not been systematically established in multi‐center trials. Herein, we perform a systematic review of the test‐retest literature on the variability of VDP, and similar metrics,

Validation of Biomarkers Z‐AAT Polymers and Fibrinopeptide Aα‐Val541 in Peripheral Blood of Patients With pi*ZZ Alpha‐1 Antitrypsin Deficiency

Liver International Communications, Volume 6, Issue 3, September 2025.
ABSTRACT Alpha‐1 antitrypsin (AAT) deficiency is a monogenetic condition caused by various single mutations in the SERPINA1 gene. Homozygous carriage of the Z allele (Pi*ZZ) increases the risk of pulmonary emphysema and liver cirrhosis. Z‐AAT polymerises and accumulates in hepatocytes, causing liver damage.

Activated Interferon‐γ‐Positive T Lymphocytes and Cytokine Signatures in Patients With Postinfectious Cough

MedComm, Volume 6, Issue 9, September 2025.
Postinfectious cough patients have elevated levels of activated IFN‐γ+ T lymphocytes in blood. Postinfectious cough patients exhibit airway inflammatory signatures characterized by activated IFN‐γ+ T‐lymphocytes and elevated levels of IFN‐γ, TNF‐α, IFN‐α, IFN‐β, and IL‐10.
