The content of noradrenaline in the lungs, pulmonary arteries and veins was found to be reduced at definite stages of traumatic shock. At the same time the level of oleic acids was decreased in pulmonary lipid fractions. The content of adrenaline rose in the pulmonary arteries and veins, and it was high in the blood collected from the right atrium as compared to the blood from the carotid artery. It is assumed that the changes in the content of fatty acids are linked with those occurring in lung catecholamine metabolism.

Sotatercept in pulmonary hypertension and beyond.

Eur J Clin Invest

Department of Surgical, Medical and Molecular Pathology and Critical Area, Laboratory of Biochemistry, University of Pisa, Pisa, Italy.

Sotatercept binds free activins by mimicking the extracellular domain of the activin receptor type IIA (ACTRIIA). Additional ligands are BMP/TGF-beta, GDF8, GDF11 and BMP10. The binding with activins leads to the inhibition of the signalling pathway and the deactivation of the bone morphogenic protein (BMP) receptor type 2.

Atypical pulmonary manifestations suggestive of lung cancer in behçet's disease with spontaneously regressing lymphadenopathy and a lung mass: a case report.

BMC Pulm Med

January 2025

Division of Pulmonology and Critical Care Medicine, Department of Internal Medicine, College of Medicine, Chungnam National University, Daejeon, 301-721, Republic of Korea.

Background: Behçet's disease (BD) is a multisystem inflammatory disorder that can affect various organs, including the lungs. Pulmonary manifestations are rare and typically present as pulmonary artery aneurysms.

Case Presentation: We report the case of a 56-year-old East Asian male with a 27-year history of BD, who had no respiratory symptoms, such as hemoptysis, cough, or fever.

Background: The binding of endothelin-1 (ET-1) to endothelin type A receptor (ETAR) performs a critical action in pulmonary arterial smooth muscle cell (PASMC) proliferation leading to pulmonary vascular structural remodeling. More evidence showed that cystathionine γ-lyase (CSE)-catalyzed endogenous hydrogen sulfide (HS) was involved in the pathogenesis of cardiovascular diseases. In this study, we aimed to explore the effect of endogenous HS/CSE pathway on the ET-1/ETAR binding and its underlying mechanisms in the cellular and animal models of PASMC proliferation.

The pathogenesis of chronic thromboembolic pulmonary hypertension may be multifactorial and requires further studies. We explored alterations in pulmonary artery endothelial cells under the hypoxic and elevated interleukin-17 conditions that are commonly present in patients with chronic thromboembolic pulmonary hypertension. We measured the serum interleukin-17 levels in 10 chronic thromboembolic pulmonary hypertension patients and 10 healthy control persons.

Division of Cardiac Surgery, Department of Surgery, Faculty of Medicine, University of Alberta, Edmonton, Canada.

Introduction: Preclinically, 24-hour continuous Ex-Situ Lung Perfusion (ESLP) is the longest duration achieved in large animal models and rejected human lungs. Here, we present our 36-hour Negative Pressure Ventilation (NPV)-ESLP protocol applied to porcine and rejected human lungs.

Methods: Five sets of donor domestic pig lungs (45-55 kg) underwent 36-hour NPV-ESLP.
