This review presents the literature data of new approaches for the treatment of COVID-19 with low doses of radiation (LDR). In addition, data on the use of LDR for the treatment of various disorders, in particular pneumonia, a number of inflammatory processes of various etiology, as well as Alzheimer's disease are discussed. The mechanisms of LDR action are briefly described, associated with the activation of the immune system and antiinflammatory response due to the effect on the processes of oxidative stress, which is reflected in an increase in the activity of cytokines (interleukin- (IL-) 6), changes in the expression of a number of genes (such as P53 and NF-κB (p65)) and long non-coding RNAs (ncRNAs) (the authors' own data are presented). Based on the analysis of the material presented, it can be assumed that further clinical trials of the effect of MDR (5-10 cGy) on patients with COVID-19, who are at different stages of the disease, will reveal the optimal conditions for the development and use of an effective treatment regimen.

Lung cancer is the leading cause of cancer-related mortality worldwide, highlighting the urgent need for more accurate and minimally invasive diagnostic tools to improve early detection and patient outcomes. While low-dose computed tomography (LDCT) is effective for screening in high-risk individuals, its high false-positive rate necessitates more precise diagnostic strategies. Liquid biopsy, particularly ctDNA methylation analysis, represents a promising alternative for non-invasive classification of indeterminate pulmonary nodules (IPNs).

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that causes extensive inflammation and tissue destruction across several organs. Conventional therapies, such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and immunosuppressive drugs, can have serious adverse effects and are not always successful. This study looks at the possibility of low-dose interleukin-2 (IL-2) therapy as a new treatment for SLE, focusing on its mechanics, effectiveness, and clinical applicability.

Article Synopsis
- Graft-versus-host disease (GVHD) is a serious complication after allogeneic hematopoietic cell transplantation, significantly affecting patient survival and quality of life due to poor responses to current treatments.
- The review highlights the crucial role of Interleukin-2 (IL-2) in GVHD pathogenesis, particularly its influence on the balance between regulatory T cells (Tregs) and effector T cells (Teffs).
- It discusses emerging therapies involving low-dose IL-2, combination treatments, and novel strategies like modified IL-2 complexes to improve Treg function and reduce Teff activation, offering hope for more effective GVHD management.

Background: Optimization of the dose the patient receives during scanning is an important problem in modern medical X-ray computed tomography (CT). One of the basic ways to its solution is to reduce the number of views. Compressed sensing theory helped promote the development of a new class of effective reconstruction algorithms for limited data CT.
