Epithelial cells/progenitor cells in developing human lower respiratory tract: Characterization and transplantation to rat model of pulmonary injury.

Introduction: For cell-based therapies of lung injury, several cell sources have been extensively studied. However, the potential of human fetal respiratory cells has not been systematically explored for this purpose. Here, we hypothesize that these cells could be one of the top sources and hence, we extensively updated the definition of their phenotype.

The association between workload and quality of work life of nurses taking care of patients with COVID-19.

Background: The COVID-19 epidemic has brought significant changes and complexities to nurses' working conditions. Given the crucial role of health workers, particularly nurses, in providing healthcare services, it is essential to determine the nurses' workload, and its association with the quality of work life (QWL) during COVID-19 epidemic, and to explain the factors predicting their QWL.

Methods: A total of 250 nurses, who provided care for patients with COVID-19 in Imam Hossein Hospital of Shahrud, and met the inclusion criteria, were considered the samples in the present cross-sectional study in 2021-2022.

Pleural CEA, CA-15-3, CYFRA 21-1, CA-19-9, CA-125 discriminating malignant from benign pleural effusions: Diagnostic cancer biomarkers.

Introduction: There is a need for a rapid, accurate, less-invasive approach to distinguishing malignant from benign pleural effusions. We investigated the diagnostic value of five pleural tumor markers in exudative pleural effusions.

Methods: By immunochemiluminescence assay, we measured pleural concentrations of tumor markers.
