Association of the Gene's Single-Nucleotide Variant Rs1815739 (R577X) with Sports Qualification and Competitive Distance in Caucasian Athletes of the Southern Urals.

Unlabelled: An elite athlete's status is associated with a multifactorial phenotype depending on many environmental and genetic factors. Of course, the peculiarities of the structure and function of skeletal muscles are among the most important characteristics in the context of athletic performance.

Purpose: To study the associations of SNV rs1815739 (C577T or R577X) allelic variants and genotypes of the gene with qualification and competitive distance in Caucasian athletes of the Southern Urals.

Candidate Genes of Regulation of Skeletal Muscle Energy Metabolism in Athletes.

All biological processes associated with high sports performance, including energy metabolism, are influenced by genetics. DNA sequence variations in such genes, single nucleotide variants (SNVs), could confer genetic advantages that can be exploited to achieve optimal athletic performance. Ignorance of these features can create genetic "barriers" that prevent professional athletes from pursuing a career in sports.

The Role of Polymorphisms in Collagen-Encoding Genes in Intervertebral Disc Degeneration.

(1) Background: The purpose of this review is to analyze domestic and foreign studies on the role of collagen-encoding genes polymorphism in the development of intervertebral discs (IVDs) degeneration in humans. (2) Methods: We have carried out a search for full-text articles published in e-Library, PubMed, Oxford Press, Clinical Case, Springer, Elsevier and Google Scholar databases. The search was carried out using keywords and their combinations.

The "Angiogenic Switch" and Functional Resources in Cyclic Sports Athletes.

Regular physical activity in cyclic sports can influence the so-called "angiogenic switch", which is considered as an imbalance between proangiogenic and anti-angiogenic molecules. Disruption of the synthesis of angiogenic molecules can be caused by local changes in tissues under the influence of excessive physical exertion and its consequences, such as chronic oxidative stress and associated hypoxia, metabolic acidosis, sports injuries, etc. A review of publications on signaling pathways that activate and inhibit angiogenesis in skeletal muscles, myocardium, lung, and nervous tissue under the influence of intense physical activity in cyclic sports.

Prospects for the Personalized Multimodal Therapy Approach to Pain Management via Action on NO and NOS.

Chronic pain syndromes are an important medical problem generated by various molecular, genetic, and pathophysiologic mechanisms. Back pain, neuropathic pain, and posttraumatic pain are the most important pathological processes associated with chronic pain in adults. Standard approaches to the treatment of them do not solve the problem of pain chronicity.
