A hundred and seventy one patients with revealed rounded lung formations of tuberculous and non-tuberculous origins were examined. Mycobacterial antigens, cellular antituberculosis immunity, and antituberculosis antigens were determined. Cellular sensitization to mycobacterial antigens was found to develop in about 50% of patients with round lung formations of tuberculous origin. This sensitization to PPD was more revealed by BTR rather than by TMR. At the same time, the latter is positive in healthy donors and in patients with non-tuberculous abnormality. Finally it can be concluded that cell tests are little suitable for immunodiagnosis of tuberculosis. It was also ascertained that determination of antituberculosis antigens and antigenemia might be a important component of examinations of patients with rounded lung formations in order to make a differential diagnosis of tuberculosis and non-tuberculous abnormality as with their determination, high sensitivity and specificity of appropriate tests can be achieved. These tests are more informative for the immunodiagnosis of tuberculosis than that of infiltrative tuberculosis.

Background: Maternal nutrition profoundly influences offspring health, impacting both prenatal and early postnatal development. Previous studies have demonstrated that maternal dietary habits can affect key developmental pathways in the offsprings, including those related to lung function and disease susceptibility. However, the sex-specific impact of a maternal high-salt diet (HSD) on offspring lung injury remains poorly understood.

Donor Specific Antibodies in Extracorporeal Membrane Oxygenation-Bridged Lung Transplant Recipients.

Department of Pulmonary and Critical Care Medicine, University of Pennsylvania, Philadelphia, Pennsylvania.
Background: Extracorporeal membrane oxygenation (ECMO) is increasingly used as a bridge to lung transplantation. Although other mechanical circulatory support devices have been associated with anti-human leukocyte antigen antibody formation, including de novo donor-specific antibodies (dnDSA), it is unknown whether ECMO is a sensitizing exposure.
Methods: This was a single-center retrospective cohort study of lung transplant recipients.
Multiple Lung Resections for Metastases from Pheochromocytoma to Reduce Catecholamine Production.

A pheochromocytoma is a malignant tumor with metastatic potential. Moreover, the cardiovascular effects of abnormal amounts of catecholamines resulting from pheochromocytoma impact prognosis. Resection of the primary tumor is useful for reducing catecholamine production; however, the significance of resection of metastases remains unclear.

Disturbances in intracellular copper (Cu) homeostasis can trigger cuproptosis, a new form of cell death, which, when combined with photothermal therapy (PTT), offers a promising solution to the persistent challenges in colorectal cancer (CRC) treatment. In this study, a "three-level nanoparticle rocket" strategy is developed by engineering CuO, a multifunctional Cu-based nanoenzyme that is photothermal and has electron transfer properties and antioxidant efficiency. CuO effectively remodels the inflammatory environment by scavenging reactive oxygen species, thereby overcoming the traditional limitations of PTT.
