The use of an Inhaled Surfactant in Patients With Severe and Extremely Severe new Coronavirus Infection COVID-19 With Concomitant Cardiovascular Pathology.

Aim      To study the effectiveness of nebulized surfactant therapy as a part of a multimodality treatment of severe and extremely severe COVID-19 viral pneumonia with concomitant cardiovascular diseases (CVDs).Material and methods  This retrospective controlled study analyzed a multimodality treatment of 38 patients with severe and extremely severe COVID-19 viral pneumonia and concomitant CVDs who were administered nebulized surfactant for correction of acute respiratory distress syndrome (ARDS). The control group consisted of 105 patients with severe and extremely severe novel coronavirus infection with concomitant CVDs who were not administered surfactant as a part of the multimodality therapy.

Histological Justification for the Need of Radiofrequency Ablation of Pulmonary Arteries in Patients with High-Grade Secondary Pulmonary Hypertension.

Unlabelled: was to perform a histological assessment of the effectiveness of radiofrequency exposure for circular denervation of the pulmonary artery in patients with secondary high pulmonary hypertension.

Materials And Methods: The study was carried out on the autopsy material derived from non-operated patients. Three groups were formed.

An x-ray emission and density functional theory study of the electronic structure of Zn(1-x)Mn(x)S.

Mn 3d electronic states in the dilute magnetic semiconductor Zn(1-x)Mn(x)S (x = 0.1-0.3) are studied using soft x-ray emission (XES) measurements and density functional theory (DFT).
