Abstract
The COVID-19 pandemic has highlighted pressing challenges in biomedical research methodology. It has become obvious that the rapid and effective development of treatments for "new" viral infections is impossible without the coordination of interdisciplinary research and in-depth analysis of data obtained within the framework of the post-genomic paradigm. Presents the results of a systematic computer analysis of 290,000 scientific articles on COVID-19, with an emphasis on the results of post-genomic studies of SARS-CoV-2. The futility of the overly simplified approach, which considers only one "most important receptor protein", only one "key virus gene", etc., is shown. It is shown how post-genomic technologies will make it possible to find informative biomarkers of severe coronavirus infection, including those based on complex immune disorders associated with COVID-19.

Abstract
AIM To investigate the antitumor effects of human placenta hydrolysate (HPH) peptides on three hormone-dependent human cell lines: prostate adenocarcinoma, breast carcinoma, and ovarian cancer by metabolic analysis of cell cultures. MATERIALS AND METHODS The effect of HPH on tumor and control tumor cell lines was evaluated. Study stages: (A) de novo peptide sequencing by collision-induced dissociation mass spectrometry; (B) detection of peptides with anti-tumor properties; (C) expert analysis of the obtained lists of peptides. RESULTS Dose-dependent cytotoxic effects of HPH on three tumor cell lines are shown: PC-3 (human prostate adenocarcinomas), OAW-42 (human ovarian cancer), BT-474 (human breast carcinomas), and IC50 constants (1.3-2.8 mg/ml) were obtained. The analysis of the HPH peptide fraction showed more than 70 peptides with antitumor properties in the composition of this HPH, including kinase inhibitors: mitogen-activated protein kinases, kappa-bi nuclear factor inhibitor kinase, AKT serine/threonine kinase 1, protein kinase C zeta, interleukin-1 receptor-associated kinase 4 and cyclin-dependent kinase 1. CONCLUSION The results of the study indicate not only the oncological safety of the HPH used in therapy but also the mild antitumor effects of this HPH at high concentrations.

Abstract
BACKGROUND Human placenta hydrolysates (HPH), the study of which was initiated by the scientific school of Vladimir P. Filatov, are currently being investigated using modern proteomic technologies. HPH is a promising tool for maintaining the function of mitochondria and regenerating tissues and organs with a high content of mitochondria (liver, heart muscle, skeletal muscles, etc.). The molecular mechanisms of action of HPH are practically not studied. AIM Identification of mitochondrial support mitochondrial function-supporting peptides in HPH (Laennec, produced by Japan Bioproducts). MATERIALS AND METHODS Data on the chemical structure of the peptides were collected through a mass spectrometric experiment. Then, to establish the amino acid sequences of the peptides, de novo peptide sequencing algorithms based on the mathematical theory of topological and metric analysis of chemographs were applied. Bioinformatic analysis of the peptide composition of HPH was carried out using the integral protein annotation method. RESULTS The biological functions of 41 peptides in the composition of HPH have been identified and described. Among the target proteins, the activity of which is regulated by the identified peptides and significantly affects the function of mitochondria, are caspases (CASP1, CASP3, CASP4) and other proteins regulating apoptosis (BCL2, CANPL1, PPARA), MAP kinases (MAPK1, MAPK3, MAPK4, MAPK8, MAPK9 , MAPK10, MAPK14), AKT1/GSK3B/MTOR cascade kinases, and a number of other target proteins (ADGRG6 receptor, inhibitor of NF-êB kinase IKKE, pyruvate dehydrogenase 2/3/4, SIRT1 sirtuin deacetylase, ULK1 kinase). CONCLUSION HPH peptides have been identified that promote inhibition of mitochondrial pore formation, apoptosis, and excessive mitochondrial autophagy under conditions of oxidative/toxic stress, chronic inflammation, and/or hyperinsulinemia.

Abstract
This Expert Council focuses on the meta-analysis of studies on the risk of atrial fibrillation (AF) in patients taking omega-3 polyunsaturated fatty acids (PUFA) and of data on the omega-3 PUFA treatment in patients with cardiovascular and kidney diseases.The major statements of the Expert Council: the meta-analysis of AF risk in patients taking omega-3 PUFA showed an increased risk of this arrhythmia. However, it should be taken into account that the risk of complications was low, and there was no significant increase in the risk of AF when omega-3 PUFA was used at a dose of ≤1 g and a standard dose of the only omega-3 PUFA drug registered in the Russian Federation, considering all AF episodes in the ASCEND study.At the present time, according to Russian and international clinical guidelines, the use of omega-3 PUFA can be considered in the following cases: • for patients with chronic heart failure (CHF) with reduced left ventricular ejection fraction as a supplement to the basic therapy (2B class of recommendations according to the 2020 Russian Society of Cardiology guidelines (RSC) and the 2022 AHA / ACC / HFSA guidelines); • for patients with hypertriglyceridemia (>1.5 mmol/l) as a part of combination therapy (IIb class of recommendations and B level of evidence according to the 2021 European guidelines on cardiovascular disease prevention, etc.); • for adult patients with stage 3-4 chronic kidney disease (CKD), long-chain omega-3 PUFA 2 g/day is recommended for reducing the level of triglycerides (2C class of recommendations). Data on the use of omega-3 PUFA for other indications are heterogenous, which can be partially explained by using different form and doses of the drugs.

Abstract
The main pharmacological use of etifoxine is the treatment of psychosomatic manifestations of anxiety. The purpose of this work is a systematic analysis of fundamental and clinical studies of etifoxine. In addition to the anxiolytic effect, which partially persists even after discontinuation of therapy, etifoxine is characterized by analgesic, neurotrophic and neuroprotective properties. Such a pharmacological profile of etifoxine is due not only to the activation of GABA receptors, but also to the effect on the levels of neurosteroids in the blood and in the brain. Modulation by etifoxine of neurosteroids' metabolism contributes to the manifestation of anxiolytic, anti-inflammatory, neuroprotective and other properties of etifoxine.

Abstract
In the treatment of joint diseases, including osteoarthritis (OA), the use of standardized extracts of undenatured type II collagen (UDC-II) is promising. It is known that UDC-II is involved in the regulation of innate and adaptive immunity (reduction of autoimmune reactions that stimulate cartilage degradation) and in the reduction of chronic inflammation activity (modulation of cytokines and prostaglandins). The effect of UDC-II on discoidin receptors of chondrocytes helps to prevent structural disorders of the cartilage connective tissue. Experimental and clinical studies have shown that under the influence of standardized UDC-II, there is an increase in the proportion of regulatory CD4+ T cells, a decrease in the levels of pro-inflammatory cytokines, such as interleukin (IL) 1β, IL6, tumor necrosis factor α, CRP, prostaglandins in the blood, as well as matrix metalloproteinase 3 and NF-κB expression in cartilage. The use of UDC-II in OA leads to a significant reduction in pain, an increase in the range of joint motion, an improvement in joint function according to WOMAC and quality of life.

Abstract
OBJECTIVE Systematization of the array of publications on cytidyldiphosphocholine (CDP-choline). MATERIAL AND METHODS Systematic computer analysis of all currently available publications on CDP-choline (1750 publications in PUBMED) using the topological theory of big data analysis. RESULTS CDP-choline is essential for acetylcholine biosynthesis, phospholipid metabolism, and DNA methylation. The article describes the effects of CDP-choline on acetylcholinergic and other types of neurotransmission, anti-inflammatory, neuroprotective and neurotrophic effects of CDP-choline. Also, the paper presents the effects of the molecule on lipid metabolism and gene expression within the post-genomic paradigm (in particular, an increase in the expression of nicotinic and muscarinic acetylcholine receptors). The results of fundamental and clinical studies of CDP-choline in the treatment of cognitive impairments associated with cerebral ischemia and neurodegeneration are presented. CONCLUSION The pharmacological effects of CDP-choline are mediated through multiple molecular mechanisms that contribute to the nootropic action of this molecule.

Abstract
Objective: to carry out a systematic computer-assisted analysis of scientific literature on on the relationships between the effects of vitamin and nociception (including the impact of vitamin D deficiency on the development of pain syndrome.Material and methods. For the query “(pain OR nociception) AND (vitamin D OR cholecalciferol OR VITD OR CALCITRIOL OR HYDROXYVITAMIN OR DIHYDROXYVITAMIN OR ALPHACALCIDOL)", 2318 references, including 77 references on alpha-calcidol, were found in the biomedical publications database PubMed. The computer-assisted analysis of this array of publications was carried out using the current big data analysis methods developed within the topological and metric approaches to recognition/classification problems.Result and discussion. A systematic computer-assisted text analysis of 2318 studies on the relationships between nociception and vitamin D showed that the analgesic effects of the vitamin are by anti-inflammatory action and the regulation of serotonergic, dopaminergic, and opioidergic neurotransmission. The lower blood levels of the major vitamin D metabolite 25 (OH)D is a risk factor for decreased pain threshold in myalgia, fibromyalgia, arthralgia, dorsalgia, and a number of neuralgias.Conclusion. In patients with impaired renal conversion of active vitamin D metabolites (especially in the elderly), the efficacy of cholecalciferol-based drugs is reduced, which makes it necessary to use the active forms of vitamin D.

Objective: to investigate the effect of citicoline (CTC) on gene transcription.Material and methods. Chemotranscriptome analysis of the CTC molecule was carried out on an NPC.TAK model, provided that the cells were incubated with CTC for 24 hours.Results and discussion. CTC dose-dependently affected the transcription of 8,838 out of 12,716 annotated human genes, mainly by increasing the transcription of the genes involved: 1) in the neurotransmitter metabolism of serotonin (n=36), dopamine (n=32), GABA (n=14), and acetylcholine (n=27); 2) in showing the effects of neurotrophic factors (n=152), including nerve growth factor (n=11); 3) in maintaining the cardiovascular system (vasodilation and cardiac electrical activity; a total of 76 genes). CTC reduced the transcription of the genes, whose protein activity supported inflammation (n=86) and cell division (n=656). CTC elevated the expression of 60 genes involved in triglyceride processing and decreased the expression of 51 genes whose proteins were involved in cholesterol metabolism. CTC increased the transcription of the genes involved in the body’s response to various drugs, including antiepileptic drugs (n=20), dopaminergic agents (n=19), antipsychotics (n=38), anxiolytics (n=21), sedatives (n=22), antidepressants (n=35), anesthetics (n=23), and antidementia drugs (n=11).Conclusion. Chemotranscriptome analysis indicated the positive effect of CTC on neurotransmission, neuroprotection, lipid profile, and a higher neuronal susceptibility to other neuroactive drugs.

Abstract
Objective: to investigate the effect of dexketoprofen on the severity of seizures on a rat model of primary generalized seizures caused by thiosemicarbazide; to evaluate the neuroprotective effect of the drug.Material and methods. The investigation was conducted on 72 male albino rats weighing 200–300 g. The animals were given dexketoprofen and/or comparison drugs (gabapentin, sodium valproate) for 5 days, after which the seizure model was reproduced. The effects of the drugs were evaluated from a set of neurological tests and the results of a histopathological examination of the brain.Results and discussion. Dexketoprofen reduced the severity, duration, and number of primary generalized seizures and potentiated the anticonvulsant effects of gabapentin and sodium valproate. Histopathological and morphometric examinations of the rat brain showed that dexketoprofen inhibited the formation of irreversible neuronal changes (27.2%; control, 55.7%), by transferring them into reversible changes (47.7%; control, 21.8%).Conclusion. The investigation made it possible to conclude that dexketoprofen had a moderate neuroprotective effect neurologically and morphometrically verified.

Abstract
Background Effects of drugs and biologically active supplements based on omega-3 polyunsaturated fatty acids (ω3 PUFA) considerably depend on the standardized content of eicosatetraenoic acid (EPA), docosahexaenoic acid (DHA), and other fatty acids in the extracts.Material and methods In this study, we comprehensively examined the composition of 10 ω3 PUFA samples with chromatographic measurement of more than 40 metabolites of fatty acids and other compounds. The data on extract composition were analyzed with current methods of intelligent data analysis (metric condensation method; multidimensional scaling; principal component analysis with axis identification; topology-metrical approach to recognition).Results Quantitative markers were obtained, which allowed separating the standardized ω3 PUFA-based samples (Omacor, Solgar omega-3 700, Femibion Natalker-2, Omega-3 concentrate, Omegamama) from less standardized ones (Fish oil-Teva, Omegatrin, Omeganol, etc.) based on results of a chromatographic analysis of fatty acid composition in the studied samples (EPA+DHA marker, ω6+ω11 marker, and standardization coefficient showing conformity of measured ω3 PUFA levels with the content stated by the manufacturer).Conclusions Among the studied samples, the pharmaceutical product Omacor showed the best values of standardization indexes.

Abstract
AIM To perform a chemoreactome modeling of the pharmacological central effects of 4 non-steroidal anti-inflammatory drugs (NSAIDs): dexketoprofen, ketoprofen, aceclofenac, lornoxicam. MATERIAL AND METHODS An analysis of the pharmacological spectrum of the central action of dexketoprofen, ketoprofen, aceclofenac and lornoxicam was based on the chemoinformatic approach, which compared drug-likeness properties with public and commercial software. RESULTS The effectiveness of NSAIDs is related to the inhibition of cannabinoid receptors CB-1, the vanilloid receptor TRPV1, NMDA and AMPA receptors and of the GABA reuptake transporter, with dexketoprofen being the most effective inhibitor. The safety of the central effects of NSAID is due to weak interactions of the NSAIDs studied with opioid, adrenergic, serotonin and dopamine receptors. Chemoreactome modeling made it possible to compare the particulars of the effects of the studied NSAIDs on experimental pain and cramps. CONCLUSION Inhibition of CB-1, TRPV1, NMDA, AMPA, GABA transporter by the NSAID molecules corresponds to a decrease in the intensity of nociceptive signals. A weak intervention of the studied NSAIDs in opioid, adrenergic, serotonin and dopaminergic neurotransmission corresponds to a decrease in the central side-effects of NSAIDs and to a lessened antagonism of these NSAIDs towards exogenous and endogenous opioids.

Abstract
AIM To analyze the peptide composition of a light peptide fraction of cerebrolysin. MATERIAL AND METHODS Mass spectrometry (MS) with orbital ion traps and modern de novo MS-sequencing algorithms was performed. RESULTS The amino acid sequences of 14 635 peptides corresponding to the 1643 porcine proteome neuronal proteins are identified. An analysis of the human proteome annotation shows that these peptides can mimic the corresponding human peptides. In particular, 405 peptide fragments correspond to 300 known biologically active peptides, including fragments of antibacterial peptides (defensins, histatins), immunomodulatory (granulin, manserin) and vasoactive (endothelin, VIP) peptides. At the same time, 8953 of 14 635 peptides can modulate the activity of 275 human signaling proteins, including kinases CDK1, CDK2, TGFBR2, GSK3, MTOR, pro-apoptotic caspases CASP1, CASP3 and CASP6 etc. The results confirm the presence of Leu- and Met-enkephalins, fragments of neuropeptide orexin, neuropeptide VF, galanin and nerve growth factor that have a neurotrophic effect. CONCLUSION The results of a proteomic study of the peptide composition of cerebrolysin indicate the widest range of molecular mechanisms responsible for the clinical efficacy of this drug.

Abstract
AIM To establish the molecular mechanisms of the mood stabilizing (normothymic) action of the neuroprotector Cerebrolysin. MATERIAL AND METHODS Mass-spectrometric analysis of the peptide composition of cerebrolysin followed by a complex bioinformatics analysis was utilized. RESULTS Cerebrolysin contains considerable amounts of Leu- and Met-enkephalins, partial analogues of enkephalins, peptide fragments of beta-lipotropin. These peptides stimulate the endorphinergic system thus contributing to normothymic action and an increase in the levels of the brain-derived neurotrophic factor (BDNF). Specific inhibition of kinases ABL1, PINK1, CDK5 and arginine N-methyltransferase PRMT5 by the peptides of cerebrolysin has a multidirectional effect on the dopaminergic system, also helping to stabilize mood. Cerebrolysin peptides do not directly affect neither the serotonergic, adrenergic, nor GABAergic systems. CONCLUSION The normothymic effect of Cerebrolysin is due to the stabilization of endorphinergic and dopaminergic neurotransmission.

Abstract
The concurrent use of muscle relaxants and nonsteroidal anti-inflammatory drugs (NSAIDs) is a promising treatment for painful muscle hypertonia and convulsive states.Objective: to identify the most effective and safe synergist combinations of tolperisone and NSAIDs.Material and methods. A differential chemoreactome analysis was employed to evaluate the effects of the muscle relaxant tolperisone and five NSAIDs (dexketoprofen, etoricoxib, meloxicam, naproxen, and diclofenac). The biological activities of the molecules under study were assessed in five sections: 1) inhibition of the proteins of prostaglandin and leukotriene metabolism; 2) inhibition of the effects of the transcription factor nuclear factor kappa, tumor necrosis factor-, and other anti-inflammatory mechanisms; 3) inhibition of excessive blood coagulation and platelet aggregation; 4) vasodynamic effects; 5) antitumor properties on cell lines in culture.Results and discussion. Based on the differences in the pharmacological activity profiles of tolperisone and NSAIDs under study, the investigators identified the most promising synergistic combinations, in which both active ingredients complemented each other as effectively and safely as possible. The obtained estimates of the degree of synergism of various combinations of tolperisone and NSAIDs hold that the most promising antithrombotic, and antitumor effects.Conclusion. The results of this study will help adequately choose combinations of muscle relaxants and NSAIDs in patients with muscle hypertonia, which will be able to improve the efficiency and safety of treatment.

Abstract
Systematic analysis of 3 728 publications on the relationship between microelement status and chronic heart failure (CHF) was carried out. Three main areas of research have been identified: 1) magnesium, electrolytes and CHF; 2) the transcriptional and antioxidant effects of zinc, selenium, copper; 3) iron-deficiency anemia and CHF. In this paper, we consider a complex of relationships between the magnesium insufficiency and CHF, the effect of magnesium on vascular tone, mitochondria, heart rhythm and the susceptibility of cardiomyocytes to adrenergic stimulation. Using magnesium orotate for the treatment of CHF is a feasible approach to compensate magnesium insufficiency in patients with CHF.

Abstract
Muscle relaxants are used in the treatment of musculoskeletal pain. The exact molecular mechanisms of action of muscle relaxants are not always clear. Some muscle relaxants show mainly an anticholinergic effect, others have GABAergic one; they differ in accumulation in muscles, central nervous system, and other tissues.Objective:to carry out a comparative chemoreactome analysis of tolperisone with tizanidine and baclofen, allowing the pharmacological action of each of the molecules to be specified.Material and methods. The investigators applied a chemoinformational approach, i.e. compared the chemical structure of the studied molecules with the structures of millions of other molecules, for which the molecular and pharmacological properties are known. The analysis is based on the latest machine learning technologies developed within the framework of the theory of combinatorial solvability analysis, the theory of topological and metric approaches to analyzing the features of the so-called big data.Results and discussion. Tolperisone was most likely to accumulate in the skeletal muscles, adrenal cortex, and hypothalamus. The drug caused a muscle relaxant effect through cholinergic action, practically without affecting adrenergic, dopaminergic, GABAergic neurotransmission. Each of the studied molecules was established to exert dose-dependent antispasmodic and analgesic effects. Tolperisone was shown to have antithrombotic and antiinflammatory effects due to inhibition of the activity of tumor necrosis factor-a and to modulation of the metabolism ofprostaglandins and leukotrienes.Conclusion.Significant differences were found in the mechanisms of molecular action of tolperisone, tizanidine, and baclofen, which was responsible for differences in the time of onset and duration of action of a muscle relaxant, in the action on CNS or peripheral nervous system neurons, as well as in additionalpleiotropic effects and adverse reactions.

Abstract
UNLABELLED The states characterized by pronounced hypercoagulable components (deep vein thrombosis, cardio- and cerebro-vascular pathologies) are caused by multiple pathophysiological factors, including insufficient supply of magnesium (Mg) and other micronutrients. AIM to present results of analysis of the Institute of Microelements Data Base (IMDB) performed from point of view of interrelationships of Mg deficit and hypercoagulable states in adults treated in medico-preventive facilities of Central, Northwestern, Northern, and Siberian federal districts of Russia. METHODS The analysis was realized as analysis of data obtained in a cross-sectional study. In the cohort of patients (n=1453) formed from the IMBD adequacy of Mg supply was assessed by magnesium levels in blood plasma (Mg BP) (0.69±0.15 mmol/L) and estimates of daily Mg consumption according to dietary diaries (Mg D) (185±90 mg/day). RESULTS Mg supply was adequate (Mg BP >0.80 mmol/L, Mg D >300 mg/day) in not more than 6 % of patients. Presence of "Hypercoagulation" label in data base was associated with greater number of chronic diseases (2.3±2.1 and 0.83±0.8 with and without this label, respectively, р=0.0006) and elevated risk of the presence on 4 comorbid pathologies (odds ratio [OR] 18, 95 % confidence interval [CI] 10-25, р=0.0006).

Abstract
Deficiency of magnesium and vitamin 6 is a modifiable risk factor for coronary heart disease (CHD). A combined deficiency of magnesium and vitamin 6 disrupts the functioning myocardial tissue due to the formation of endothelial dysfunction, prothrombotic changes in blood viscosity characteristics, improve vascular tone, failure of the mitochondria. Receiving organic magnesium salts in combination with adequate doses of pyridoxine can be effective in the prevention and treatment of CHD.

Abstract
AIM A complex study of pharmacological properties of magnesium pyroglutamate using the modern methods of chemoinformatics and bioinformatics. MATERIAL AND METHODS Pharmacological properties of magnesium pyroglutamate were studied using chemoinformatic and bioinformatic analyses. RESULTS Neurotropic effects of magnesium pyroglutamate are due to an influence on the synthesis of neuropeptides containing pyroglutamate (orexin, thyroliberin, neurotensin etc) and due to the similarity between pyroglutamate-anion with some neuroactive components (L-theanine, 2-pirrolydinone, piracetam). CONCLUSION The results of the study suggest neuroprotective, sedative and antidepressive properties of magnesium pyroglutamate which are realized by pyroglutamate-anion in the synergism with magnesium cation.

Abstract
AIM systematization of studies of synergistic effect of potassium and magnesium on myocardial function. MATERIAL AND METHODS Analysis of an array of literature using methods of computer learning. RESULTS Synergism of potassium and magnesium is driven by common causes of deficit (low content in diet, abnormal renal function, iatrogenic causes), by potassium sparing effects of magnesium, and by regulatory properties of magnesium in processes affecting potassium binding proteins (first of all potassium rectifier channels). Magnesium and potassium exert substantial synergism in maintenance of cardiac rhythm (in particular preventing QT prolongation) and in cardioprotection. Combination administration of organic potassium and magnesium salts was shown to be effective for urgent therapy and long term prevention both as intravenous and oral formulations.
