Brain Bioelectric Responses to Short-Term Heart Rate Variability Biofeedback Training in Indian and Russian University Students Studying in the Russian Arctic.

Heart rate variability biofeedback (HRV BF) training aids adaptation to new climatic, geographical, and social environments. Neurophysiological changes during the HRV BF in individuals from tropical regions studying in the Arctic are not well understood. The aim of this study was to research electroencephalographic (EEG) changes during a single short-term HRV BF session in Indian and Russian students studying in the Russian Arctic.

Autoimmunity-Associated SNP rs3024505 Disrupts STAT3 Binding in B Cells, Leading to IL10 Dysregulation.

Interleukin 10 (IL10) is a major anti-inflammatory cytokine that acts as a master regulator of the immune response. A single nucleotide polymorphism rs3024505(C/T), located downstream of the gene, is associated with several aggressive inflammatory diseases, including systemic lupus erythematosus, Sjögren's syndrome, Crohn's disease, and ulcerative colitis. In such autoimmune pathologies, IL10-producing B cells play a protective role by decreasing the level of inflammation and restoring immune homeostasis.

[Optimization of secondary prevention in patients with high-risk atherothrombotic ischemic stroke or transient ischemic attacks].

High and very high risk atherothrombotic ischemic stroke (ATIS) includes patients with severe extracranial atherosclerosis, any intracranial atherosclerosis, and aortic arch atheromatosis. The article discusses the most effective approaches to medical short- and long-term secondary prevention of ATIS, major vascular events and death, based on the results of modern research and current clinical guidelines. Clinical studies of recent years have proven the possibility of individualization and intensification of secondary prevention of ATIS.

Cell-Molecular Interactions of Nano- and Microparticles in Dental Implantology.

The role of metallic nano- and microparticles in the development of inflammation has not yet been investigated. Soft tissue biopsy specimens of the bone bed taken during surgical revisions, as well as supernatants obtained from the surface of the orthopedic structures and dental implants (control), were examined. Investigations were performed using X-ray microtomography, X-ray fluorescence analysis, and scanning electron microscopy.
