Endothelin-1 is a potent vasoconstrictive peptide that plays an important role in ex vivo lung perfusion. ET-1 expression levels are predictive of lung transplant outcomes and represent a valuable monitoring tool for surgeons; however, traditional techniques that measure [ET-1] are not suitable for the transplant setting. Herein, we demonstrate a new assay that rapidly measures ET-1 peptide lev...

Utilizing micro-X-ray CT (μCT) imaging, we sought to generate an atlas of in vivo and intact/ex vivo lungs from normal murine strains. In vivo imaging allows visualization of parenchymal density and small airways (15-28 μm/voxel). Ex vivo imaging of the intact lung via μCT allows for improved understanding of the three-dimensional lung architecture at the alveolar level with voxel dimensions of...

CONTEXT AND OBJECTIVE Lung preservation remains a challenging issue for lung transplantation groups. Along with the development of ex vivo lung perfusion, a new preservation method known as topical-ECMO (extracorporal membrane oxygenation) has been proposed. The present study compared topical-ECMO with cold ischemia (CI) for lung preservation in an ex vivo experimental model. DESIGN AND SETTI...

OBJECTIVES The effects of cisplatin on the lung parenchyma during hyperthermic intrathoracic chemotherapy perfusion have not been analysed in detail. The objective of this study was to evaluate both the concentration and depth of the penetration of cisplatin in human lung tissue after hyperthermic exposure under ex vivo conditions. METHODS This experimental study was approved by the local eth...
