Abstract
Cardiotonic steroids (CTSs), such as digoxin, are used for heart failure treatment. However, digoxin permeates the brain-blood barrier (BBB), affecting central nervous system (CNS) functions. Finding a CTS that does not pass through the BBB would increase CTSs' applicability in the clinic and decrease the risk of side effects on the CNS. This study aimed to investigate the tissue distribution of the CTS ouabain following intraperitoneal injection and whether ouabain passes through the BBB. After intraperitoneal injection (1.25 mg/kg), ouabain concentrations were measured at 5 min, 15 min, 30 min, 1 h, 3 h, 6 h, and 24 h using HPLC-MS in brain, heart, liver, and kidney tissues and blood plasma in C57/black mice. Ouabain was undetectable in the brain tissue. Plasma: Cmax = 882.88 ± 21.82 ng/g; Tmax = 0.08 ± 0.01 h; T1/2 = 0.15 ± 0.02 h; MRT = 0.26 ± 0.01. Cardiac tissue: Cmax = 145.24 ± 44.03 ng/g (undetectable at 60 min); Tmax = 0.08 ± 0.02 h; T1/2 = 0.23 ± 0.09 h; MRT = 0.38 ± 0.14 h. Kidney tissue: Cmax = 1072.3 ± 260.8 ng/g; Tmax = 0.35 ± 0.19 h; T1/2 = 1.32 ± 0.76 h; MRT = 1.41 ± 0.71 h. Liver tissue: Cmax = 2558.0 ± 382.4 ng/g; Tmax = 0.35 ± 0.13 h; T1/2 = 1.24 ± 0.7 h; MRT = 0.98 ± 0.33 h. Unlike digoxin, ouabain does not cross the BBB and is eliminated quicker from all the analyzed tissues, giving it a potential advantage over digoxin in systemic administration. However, the inability of ouabain to pass though the BBB necessitates intracerebral administration when used to investigate its effects on the CNS.

Abstract
Derivatives of polyunsaturated fatty acids (PUFAs), also known as oxylipins, are key participants in regulating inflammation. Neuroinflammation is involved in many neurodegenerative diseases, including Parkinson's disease. The development of ultra-high-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) facilitated the study of oxylipins on a system level, i.e., the analysis of oxylipin profiles. We analyzed oxylipin profiles in the blood plasma of 36 healthy volunteers (HC) and 73 patients with Parkinson's disease (PD), divided into early (L\M, 29 patients) or advanced (H, 44 patients) stages based on the Hoehn and Yahr scale. Among the 40 oxylipins detected, we observed a decrease in the concentration of arachidonic acid (AA) and AA derivatives, including anandamide (AEA) and Leukotriene E4 (LTE4), and an increase in the concentration of hydroxyeicosatetraenoic acids 19-HETE and 12-HETE (PD vs HC). Correlation analysis of gender, age of PD onset, and disease stages revealed 20 compounds the concentration of which changed depending on disease stage. Comparison of the acquired oxylipin profiles to openly available PD patient brain transcriptome datasets showed that plasma oxylipins do not appear to directly reflect changes in brain metabolism at different disease stages. However, both the L\M and H stages are characterized by their own oxylipin profiles - in patients with the H stage oxylipin synthesis is increased, while in patients with L\M stages oxylipin synthesis decreases compared to HC. This suggests that different therapeutic approaches may be more effective for patients at early versus late stages of PD.

Abstract
Overexposure to Mn causes a neurological disorder-manganism-with motor symptoms that overlap closely with disorders associated with haploinsufficiency in the gene encoding for α3 isoform of Na+,K+-ATPase (NKA). The present study was designed to test the hypothesis that behavioral changes in the mouse model of manganism may be associated with changes in the expression and activity of α3 NKA in the cerebellum (CB) and striatum (STR)-the key brain structures responsible for motor control in adult mice. C57Bl/6 mice were exposed to MnCl2 at 0.5 g/L (in drinking water) for up to eight weeks. After four weeks of Mn consumption, Mn levels were increased in the CB only. Behavioral tests demonstrated decreased performance of Mn-treated mice in the shuttle box test (third through sixth weeks), and the inclined grid walking test (first through sixth weeks), suggesting the development of learning impairment, decreased locomotion, and motor discoordination. The activity of NKA significantly decreased, and the expression of α1-α3 isoforms of NKA increased in the second week in the CB only. Thus, signs of learning and motor disturbances developing in this model of manganism are unlikely to be directly linked to disturbances in the expression or activity of NKA in the CB or STR. Whether these early changes may contribute to the pathogenesis of later behavioral deficits remains to be determined.

Abstract
In recent years, enough evidence has accumulated to assert that cardiotonic steroids, Na+,K+-ATPase ligands, play an integral role in the physiological and pathophysiological processes in the body. However, little is known about the function of these compounds in the central nervous system. Endogenous cardiotonic steroids are involved in the pathogenesis of affective disorders, including depression and bipolar disorder, which are linked to dopaminergic system dysfunction. Animal models have shown that the cardiotonic steroid ouabain induces mania-like behavior through dopamine-dependent intracellular signaling pathways. In addition, mutations in the alpha subunit of Na+,K+-ATPase lead to the development of neurological pathologies. Evidence from animal models confirms the neurological consequences of mutations in the Na+,K+-ATPase alpha subunit. This review is dedicated to discussing the role of cardiotonic steroids and Na+,K+-ATPase in dopaminergic system pathologies-both the evidence supporting their involvement and potential pathways along which they may exert their effects are evaluated. Since there is an association between affective disorders accompanied by functional alterations in the dopaminergic system and neurological disorders such as Parkinson's disease, we extend our discussion to the role of Na+,K+-ATPase and cardiotonic steroids in neurodegenerative diseases as well.

Abstract
The effect of temperature on the effectiveness of the incorporation of deuterium into pyrrolylcarnosine (PC) was studied. Deuterium gas and heavy water were used as a source of deuterium. Isotope exchange was carried out using solid-phase and liquid-phase methods. It was found that it is better to use isotope exchange with deuterated water to obtain preparative amounts of labeled pyrrolylcarnosine. When using y solid-phase method, the main label is in pyrrole. The incorporation of deuterium at a higher temperature occurs more evenly. In addition, the use of deuterated water made it possible to reduce the amount of unlabeled isotopomer to almost 0% and to obtain a product with a yield of 70% and a content of more than seven deuterium atoms. It was established that the content of deuterium in the compound can be increased by pretreating the reaction mixture with deuterium gas. This approach opens up additional opportunities for the synthesis of labeled compounds.

Abstract
L-Carnosine (β-alanyl-L-histidine) is a well-known antioxidant and neuroprotector in various models on animals and cell cultures. However, while there is a plethora of data demonstrating its efficiency as a neuroprotector, there is a distinct lack of data regarding the mechanism of its take up by neurons. According to literature, cultures of rat astrocytes, SKPT cells and rat choroid plexus epithelial cells take up carnosine via the H+-coupled PEPT2 membrane transporter. We've assessed the effectiveness and mechanism of carnosine transport, and its stability in primary rat cortical culture neurons. We demonstrated that neurons take up carnosine via active transport with Km = 119 μM and a maximum velocity of 0.289 nmol/mg (prot)/min. Passive transport speed constituted 0.21∙10-4 nmol/mg (prot)/min (with 119 μM concentration in the medium)-significantly less than active transport speed. However, carnosine concentrations over 12.5 mM led to passive transport speed becoming greater than active transport speed. Using PEPT2 inhibitor zofenopril, we demonstrated that PEPT2-dependent transport is one of the main modes of carnosine take up by neurons. Our experiments demonstrated that incubation with carnosine does not affect PEPT2 amount present in culture. At the same time, after removing carnosine from the medium, its elimination speed by culture cells reached 0.035 nmol/mg (prot)/min, which led to a decrease in carnosine quantity to control levels in culture within 1 h. Thus, carnosine is taken up by neurons with an effectiveness comparable to that of other PEPT2 substrates, but its elimination rate suggests that for effective use as a neuroprotector it's necessary to either maintain a high concentration in brain tissue, or increase the effectiveness of glial cell synthesis of endogenous carnosine and its shuttling into neurons, or use more stable chemical modifications of carnosine.

Abstract
OBJECTIVE The objective of this study was to determine if Divaza, a drug with nootropic and antioxidant effects, was safe and effective for the correction of oxidative disturbances and to stabilize cognitive impairment in patients with cerebral atherosclerosis. STUDY DESIGN The study design consisted of a 12-week multicenter, randomized, double-blind, placebo-controlled, prospective trial in parallel groups. SETTING The setting in which the study was conducted comprised 10 clinical centers across the Russian Federation. INTERVENTIONS Patients were randomized into 2 groups and instructed to take either 2 tablets of the study drug or a placebo 3 times per day in conjunction with basic therapy. OUTCOMES The primary outcome was a change in the average endogenous antioxidant potential after the completion of the study. The blood indicators of the oxidative stress (OS) were analyzed at the baseline and then after 12 weeks of therapy using iron-induced chemiluminescence analysis. The Montreal cognitive assessment test was used as a secondary outcome measure to evaluate cognitive impairment at the end of the study. RESULTS 124 outpatients with a mean age of 60.7 ± 7.6 years were enrolled and randomly assigned to receive Divaza (n = 65) or a placebo (n = 59). An improvement of cognitive function was observed in all patients of the Divaza group at the end of the treatment; this was significantly better than the placebo group (100 [100] vs. 89.5 [89.1]%, respectively, p = 0.0272 [p = 0.0128]). The administration of Divaza restored the activity of the endogenous antioxidant system. The change in the average level of lipoprotein resistance to oxidation after 12 weeks of therapy, compared to the baseline, was significantly higher in the Divaza group (14.8 ± 14.7 [14.8 ± 14.7] seconds latent period vs. 6.4 ± 16.9 [6.9 ± 16.7] seconds in the placebo group (p = 0.007 [p = 0.0107]). CONCLUSIONS Divaza is a safe and effective therapeutic option for attenuating OS and recovery of cognitive impairment in patients with cerebral atherosclerosis.

Abstract
Cardiotonic steroids (CTS) are specific inhibitors and endogenous ligands of a key enzyme in the CNS-the Na+, K+-ATPase, which maintains and creates an ion gradient on the plasma membrane of neurons. CTS cause the activation of various signaling cascades and changes in gene expression in neurons and other cell types. It is known that intracerebroventricular injection of cardiotonic steroid ouabain causes mania-like behavior in rodents, in part due to activation of dopamine-related signaling cascades in the dopamine and cAMP-regulated phosphoprotein 32 (DARPP-32) expressing medium spiny neurons in the striatum. Dopaminergic projections in the striatum innervate these GABAergic medium spiny neurons. The objective of this study was to assess changes in the expression of all genes in human iPSC-derived expressing DARPP-32 and GABA receptors neurons under the influence of ouabain. We noted a large number of statistically significant upregulated and downregulated genes after a 16-h incubation with non-toxic concentration (30 nM) of ouabain. These changes in the transcriptional activity were accomplished with activation of MAP-kinase ERK1/2 and transcriptional factor cAMP response element-binding protein (CREB). Thus, it can be concluded that 30 nM ouabain incubated for 16 h with human iPSC-derived expressing DARPP-32 and GABA receptors neurons activates genes associated with neuronal maturation and synapse formation, by increasing the expression of genes associated with translation, vesicular transport, and increased electron transport chain function. At the same time, the expression of genes associated with proliferation, migration, and early development of neurons decreases. These data indicate that non-toxic concentrations of ouabain may induce neuronal maturation, neurite growth, and increased synaptogenesis in dopamine-receptive GABAergic neurons, suggesting formation of plasticity and the establishment of new neuronal junctions.

Abstract
Multiple organ failure in COVID-19 patients is a serious problem which can result in a fatal outcome. Damage to organs and tissues, including general lung dysfunction, develops as a consequence of ischemia, which, in turn, is caused by thrombosis in small blood vessels and hypoxia, leading to oxidative stress and inflammation. Currently, research is underway to screen existing drugs for antioxidant, antiplatelet and anti-inflammatory properties. Having studied the available publications concerning the mechanisms of damage to tissues and organs of patients with COVID-19, as well as the available treatment strategies, we propose to investigate salicyl-carnosine as a potential drug for treating COVID-19 patients. In a recent study, we described the drug's synthesis procedure, and showed that salicyl-carnosine possesses antioxidant, anti-inflammatory, and antiplatelet effects. Therefore, it can simultaneously act on the three pathogenetic factors involved in tissue and organ damage in COVID-19. Thus, we propose to consider salicyl-carnosine as a potential drug for the treatment of patients with severe cases of COVID-19 infection.

Abstract
Exposure of experimental animals to the mitochondrial toxin rotenone is considered to be a model of environmental progression of Parkinson's disease (PD). We investigated the differential vulnerability of various brain regions to generalized inhibition of complex I, induced by subcutaneous rotenone injections for the duration of 1, 3 and 7 days in both rats (2 mg/kg dosage) and mice (4 mg/kg dosage). To examine patterns of metabolic activity changes in the brain, histochemical evaluation of cytochrome C oxidase (COX) activity was performed in post mortem brain sections. Animals displayed a similar time course of neuronal loss in substantia nigra pars compacta (SNpc), reaching 44 % in mice and 42 % in rats by the 7th day. The pattern of COX activity changes, however, was different for the two species. In both experiments, metabolic changes were evident not only in the substantia nigra, but also in non-specific structures (cortex and hippocampus). In mice, a decrease in COX activity was shown mostly for the non-specific areas (V1 cortex and ventral hippocampus) after the single exposure to rotenone. Data from the experiment conducted on rats demonstrated both an acute metabolic decrease in mesencephalic structures (SNpc and nucleus ruber) after a single injection of rotenone and secondary changes in cortical structures (S1 cortex and dorsal hippocampus) after chronic 7 day exposure. These changes reflect the general effect of rotenone on neuronal metabolic rate.

Abstract
Stereotaxic intracerebral cannula implantation for neuroactive agent administration is a wide-spread method for chronic experiments requiring bypassing the blood-brain barrier in rodents. However, commercially available cannula are bulky and may interfere with animal movement or lead to their dislodging during grooming. As the number of cannula needed in one experiment, and the accompanying costs can be high, it is in the interest of researchers to produce them on their own. Custom cannula manufacturing also offers the flexibility of different cannula lengths, which is required for agent delivery to various brain structures. In this article we present a protocol for making guide cannula along with the accompanying systems required for injection, which are small, cost-effective, light, easy to make, reusable, and can be made from easily procured materials.

Abstract
Wilson’s disease (WD) is a rare autosomal recessive metabolic disorder resulting from mutations in the copper-transporting, P-type ATPase gene ATP7B gene, but influences of epigenetics, environment, age, and sex-related factors on the WD phenotype complicate diagnosis and clinical manifestations. Oxylipins, derivatives of omega-3, and omega-6 polyunsaturated fatty acids (PUFAs) are signaling mediators that are deeply involved in innate immunity responses; the regulation of inflammatory responses, including acute and chronic inflammation; and other disturbances related to any system diseases. Therefore, oxylipin profile tests are attractive for the diagnosis of WD. With UPLC-MS/MS lipidomics analysis, we detected 43 oxylipins in the plasma profiles of 39 patients with various clinical manifestations of WD compared with 16 healthy controls (HCs). Analyzing the similarity matrix of oxylipin profiles allowed us to cluster patients into three groups. Analysis of the data by VolcanoPlot and partial least square discriminant analysis (PLS-DA) showed that eight oxylipins and lipids stand for the variance between WD and HCs: eicosapentaenoic acid EPA, oleoylethanolamide OEA, octadecadienoic acids 9-HODE, 9-KODE, 12-hydroxyheptadecatrenoic acid 12-HHT, prostaglandins PGD2, PGE2, and 14,15-dihydroxyeicosatrienoic acids 14,15-DHET. The compounds indicate the involvement of oxidative stress damage, inflammatory processes, and peroxisome proliferator-activated receptor (PPAR) signaling pathways in this disease. The data reveal novel possible therapeutic targets and intervention strategies for treating WD.

Abstract
Ischemic stroke is one of the most socially important diseases characterized by impaired cerebral circulation with focal damage of the brain tissue and decreased functionality. Despite the successes of modern pharmacology, possibilities of pharmacotherapy for stroke remain limited, and the research for new drugs with neuroprotective effects that can prevent brain cell death is still relevant. In this study we have investigated the neuroprotective activity of ubiquinol as a part of an innovative form on a rat model of irreversible 24 h-cerebral ischemia with evaluation of the mechanisms of its neuroprotective effect. Ubiquinol (30 mg/kg), administered intravenously in the acute period of irreversible 24 h focal cerebral ischemia, had a direct neuroprotective effect, characterized by a decrease in the volume of brain tissue necrosis. The protective effect of ubiquinol is due to its ability to inhibit the development of oxidative stress by the direct anti-radical action, preventing the increase in the lipid hydroperoxide content in the brain tissue adjacent to the focus of necrosis, lowering the lipid oxidation rate in plasma against under conditions of increased total antioxidant activity in the brain and blood of experimental animals. In vitro experiments have shown the ability of ubiquinol to prevent cell death in primary culture of cerebral neurons of rat brain under 4 h oxygen/glucose deprivation followed by 20 h reoxygenation.

Abstract
It was shown previously that inhibition of the ubiquitous α1 isoform of Na+,K+-ATPase by ouabain sharply affects gene expression profile via elevation of intracellular [Na+]i/[K+]i ratio. Unlike other cells, neurons are abundant in the α3 isoform of Na+,K+-ATPase, whose affinity in rodents to ouabain is 104-fold higher compared to the α1 isoform. With these sharp differences in mind, we compared transcriptomic changes in rat cerebellum granule cells triggered by inhibition of α1- and α3-Na+,K+-ATPase isoforms. Inhibition of α1- and α3-Na+,K+-ATPase isoforms by 1 mM ouabain resulted in dissipation of transmembrane Na+ and K+ gradients and differential expression of 994 transcripts, whereas selective inhibition of α3-Na+,K+-ATPase isoform by 100 nM ouabain affected expression of 144 transcripts without any impact on the [Na+]i/[K+]i ratio. The list of genes whose expression was affected by 1 mM ouabain by more than 2-fold was abundant in intermediates of intracellular signaling and transcription regulators, including augmented content of Npas4, Fos, Junb, Atf3, and Klf4 mRNAs, whose upregulated expression was demonstrated in neurons subjected to electrical and glutamatergic stimulation. The role [Na+]i/[K+]i-mediated signaling in transcriptomic changes involved in memory formation and storage should be examined further.

Abstract
Oxidative stress is one of the key factors in brain tissue damage in ischemia, which indicates the appropriateness of using antioxidants under these conditions. One of the promising antioxidants for the therapy of ischemic stroke is the natural dipeptide carnosine. The neuroprotective effect of dietary carnosine administration was investigated in an experimental model of focal cerebral ischemia/reperfusion in Wistar rats. Animals received carnosine with a diet at a daily dose of 150 mg/kg for 7 days before temporary occlusion of the middle cerebral artery (MCA), performed for 60 min. At 24 h after the onset of ischemia the effect of carnosine on the area of the necrotic core was evaluated in animals. In brain tissue of animals the content of malondialdehyde (MDA), protein carbonyls (PC), total antioxidant capacity (TAC), total activity of superoxide dismutase (SOD), glutathione peroxidase (GP), catalase (CAT) and glutathione transferase (GT), content of isoprostanes and cytokines were measured. Carnosine significantly reduced the infarct size. Carnosine also increased TAC and reduced the level of MDA and isoprostanes in brain tissue. Influence of carnosine on other parameters was not detected. Thus carnosine consumed prophylactically with the diet for 7 days before the induction of ischemia by means of MCA occlusion in rats provides the direct neuroprotective effect, retains high antioxidant activity of brain tissue, reduces the level of oxidative damage markers (MDA and isoprostanes) but does not have any effect on the activity of antioxidant enzyme systems and production of cytokines in brain tissue.

Abstract
Carnosine (b-alanyl-L-histidine) is an endogenous dipeptide widely distributed in excitable tissues, such as muscle and neural tissues-though in minor concentrations in the latter. Multiple benefits have been attributed to carnosine: direct and indirect antioxidant effect, antiglycating, metal-chelating, chaperone and pH-buffering activity. Thus, carnosine turns out to be a multipotent protector against oxidative damage. However, the role of carnosine in the brain remains unclear. The key aspects concerning carnosine in the brain reviewed are as follows: its concentration and bioavailability, mechanisms of action in neuronal and glial cells, beneficial effects in human studies. Recent literature data and the results of our own research are summarized here. This review covers studies of carnosine effects on both in vitro and in vivo models of cerebral damage, such as neurodegenerative disorders and ischemic injuries and the data on its physiological actions on neuronal signaling and cerebral functions. Besides its antioxidant and homeostatic properties, new potential roles of carnosine in the brain are discussed.

Abstract
Oxidative status was assessed in different areas of the cerebral cortex of male Wistar rats under normal condition and during permanent 24-h focal ischemia. In intact animals, the level of lipid hydroperoxides in the frontal lobes of both hemispheres was by 36% higher than in other cortical areas, while total antioxidant activity was by 25% higher than in other areas. During ischemia, changes in oxidative status were localized only in the ischemic focus and penumbra zone and did not involve other cortical areas. We demonstrated for the first time a neuroprotective effect of therapeutic administration of carnosine in low doses (50 mg/kg) on parameters of the oxidative status under conditions of focal ischemia comparable to its effect of high doses (500 mg/kg) as well as its local effect in the penumbra zone. A dose-dependent effect of carnosine on antioxidant activity in the penumbra zone during ischemia was also demonstrated. These findings confirm effectiveness of not only preventive carnosine administration, but also its application in the postischemic period of the stroke.

Abstract
Synthesis of lipoilcarnosine (LipC) - a conjugated molecule based on two natural antioxidants, carnosine and a-lipoic acid, is described. Its physico-chemical, antioxidant properties and biological activity are characterized. According to reversed-phase HPLC with a UV detector, purity of the final product was 89.3%. The individuality of the obtained sodium salt of LipC was confirmed by tandem HPLC-mass spectrometry. High resistance of LipC to hydrolysis with serum carnosinase was demonstrated. The antioxidant activity of LipC measured by reaction with the formation of thiobarbituric acid reacting substances and kinetic parameters of iron-induced chemiluminescence was higher than that of carnosine and lipoic acid. LipC did not affect viability of SH-SY5Y human neuroblastoma culture cells, differentiated towards the dopaminergic type, at concentrations not exceeding 5 mM. At the concentration range of 0.1-0.25 mM LipC protected neuronal cells against 1-methyl-4-phenylpyridinium (MPP + )-induced toxicity.

Abstract
AIM By using mathematical modeling, to evaluate the impact of upper respiratory tract diseases, retro- and micrognathia, and body mass index (BMI) on nocturnal pulse oximetry indicators (oxygen saturation level and oxygen desaturation index) in outpatients examined for suspected obstructive sleep apnea syndrome (OSAS). SUBJECTS AND METHODS The study enrolled 260 subjects with a mean age of 47.8±12.0 years. All the examinees underwent outpatient pulse oximetry screening during nocturnal sleep because of suspected OSAS. Multislice spiral computed tomography was carried out to assess the paranasal sinuses and nasal septum. BMI was calculated. Variance factor analysis using an original programming application intended to create binary and ternary dispersion complexes was employed as a main mathematical tool. RESULTS There were statistically significantly sets of risk factors for OSAS: nasal septum deviation + increased BMI + male gender = 68.66%; chronic allergic rhinitis + increased BMI + male gender = 63.09%; retromicrognathia + increased BMI + male ganger = 59.48%; and chronic tonsillitis + increased BMI + male gander = 60.88%. Higher BMI and male gender are a most statistically significant set of risk factors. CONCLUSION Pulse oximetry screening during nocturnal sleep in snoring patients with suspected OSAS in combination with an assessment of age, sex, BMI, ENT comorbidity, retro- and micrognathia can predict the severity of the disease and serve as a basis for elaborating an OSAS screening program.

Abstract
Cardiotonic steroid (CTS) ouabain is a well-established inhibitor of Na,K-ATPase capable of inducing signalling processes including changes in the activity of the mitogen activated protein kinases (MAPK) in various cell types. With increasing evidence of endogenous CTS in the blood and cerebrospinal fluid, it is of particular interest to study ouabain-induced signalling in neurons, especially the activation of MAPK, because they are the key kinases activated in response to extracellular signals and regulating cell survival, proliferation and apoptosis. In this study we investigated the effect of ouabain on the level of phosphorylation of three MAPK (ERK1/2, JNK and p38) and on cell survival in the primary culture of rat cerebellar cells. Using Western blotting we described the time course and concentration dependence of phosphorylation for ERK1/2, JNK and p38 in response to ouabain. We discovered that ouabain at a concentration of 1 μM does not cause cell death in cultured neurons while it changes the phosphorylation level of the three MAPK: ERK1/2 is phosphorylated transiently, p38 shows sustained phosphorylation, and JNK is dephosphorylated after a long-term incubation. We showed that ERK1/2 phosphorylation increase does not depend on ouabain-induced calcium increase and p38 activation. Changes in p38 phosphorylation, which is independent from ERK1/2 activation, are calcium dependent. Changes in JNK phosphorylation are calcium dependent and also depend on ERK1/2 and p38 activation. Ten-micromolar ouabain leads to cell death, and we conclude that different effects of 1-μM and 10-μM ouabain depend on different ERK1/2 and p38 phosphorylation profiles.

Abstract
Dipeptide carnosine (β-alanyl-L-histidine) is a natural antioxidant, but its protective effect under oxidative stress induced by neurotoxins is studied insufficiently. In this work, we show the neuroprotective effect of carnosine in primary cultures of rat cerebellar cells under oxidative stress induced by 1 mM 2,2'-azobis(2-amidinopropane)dihydrochloride (AAPH), which directly generates free radicals both in the medium and in the cells, and 20 nM rotenone, which increases the amount of intracellular reactive oxygen species (ROS). In both models, adding 2 mM carnosine to the incubation medium decreased cell death calculated using fluorescence microscopy and enhanced cell viability estimated by the MTT assay. The antioxidant effect of carnosine inside cultured cells was demonstrated using the fluorescence probe dichlorofluorescein. Carnosine reduced by half the increase in the number of ROS in neurons induced by 20 nM rotenone. Using iron-induced chemiluminescence, we showed that preincubation of primary neuronal cultures with 2 mM carnosine prevents the decrease in endogenous antioxidant potential of cells induced by 1 mM AAPH and 20 nM rotenone. Using liquid chromatography-mass spectrometry, we showed that a 10-min incubation of neuronal cultures with 2 mM carnosine leads to a 14.5-fold increase in carnosine content in cell lysates. Thus, carnosine is able to penetrate neurons and exerts an antioxidant effect. Western blot analysis revealed the presence of the peptide transporter PEPT2 in rat cerebellar cells, which suggests the possibility of carnosine transport into the cells. At the same time, Western blot analysis showed no carnosine-induced changes in the level of apoptosis regulating proteins of the Bcl-2 family and in the phosphorylation of MAP kinases, which suggests that carnosine could have minimal or no side effects on proliferation and apoptosis control systems in normal cells.

Abstract
Methemoglobin formation was examined in erytrocytes of 16 patients with Parkinson`s disease (PD) (stage 3-4 by the Hoehn and Yahr scale). The patients receiving levodopa-containing drugs (madopar, nakom) were also treated with intramuscular injections of mexidol (daily dose 100 mg/day) for 14 days. Control group included 12 clinically healthy persons. The erythrocyte methemoglobin content was determined by electronic paramagnetic resonance (EPR) using the EPR signal intensity with g-factor 6.0. The methemoglobin content was significantly higher in erythrocytes of PD patients than in healthy donors. The complex therapy with mexidol normalized the methemoglobin content in erythrocytes of PD patients. Incubation in vitro of erythrocytes of donors and PD patients with acrolein increased the methemoglobin content, while incubation with carnosine normalized the methemoglobin content in erythrocytes of PD patients. Prophylactic (i.e. before acrolein addition) and therapeutic administration of carnosine to the incubation system with acrolein decreased the methemoglobin content to its initial level. Results of this study suggest that inclusion of the antioxidants mexidol and carnosine in the scheme of basic therapy of PD may reduce side effects associated with methemoglobinemia.

Abstract
Carnosine is an endogenous dipeptide with antiproliferative properties. Here we show that carnosine selectively inhibits proliferation of human glioblastoma cells (U-118-MG) compared to breast (MB231) and oral (Cal27 and FaDu) cancer cells. Carnosine-induced inhibition of U-118-MG proliferation is associated with a significant: decrease in cellular reactive oxygen species levels, increase in manganese superoxide dismutase (MnSOD) and increase in cyclin B1 expression resulting in G2-block. We conclude that the antiproliferative property of carnosine is due to its ability to enhance MnSOD and cyclin B1 expression. These results will be of significance to the potential application of carnosine in brain cancer therapy.

Abstract
L-Amino acid oxidases (L-ААО, EC 1.4.3.2) comprise a group of flavoproteins, catalyzing oxidative deamination of L-alpha amino acids to the corresponding alpha-keto acids, NH3 and Н2О2. In most cases these enzymes present homodimeric molecules with a molecular mass of 100-150 kDa, which were shown to possess antiviral, antifungal and antitumor activity. L-lysine alpha-oxidase (LO) holds an outstanding place among this group of enzymes and its biological role may differ significantly from the other L-AAO, because it cleaves an essential amino acid - L-lysine without significant action on the other amino acids. Although much research has examined LO effects in the organism, the molecular basis of these effects is yet to be identified. To fill this gap, the present work addressed one of hypothetical mechanisms of LO biological action using the enzyme from Trichoderma cf. aureoviride Rifai ВКМF-4268D and rat pheochromocytoma PC-12 as a model cell line. Using flow cytometry a dose-dependent cytotoxicity of LO was shown. The significant growth of intracellular reactive oxygen species levels, detected by 2,7-dichlorodihydrofluorescein assay, implies generation of peroxide as one of the molecular mechanisms of LO cytotoxic action, although this does not rule out other probable ways of LO action in the organizm.

Abstract
We have used an original chromatography/mass spectrometry technique to study the pharmacokinetics of dipeptide carnosine in C57 Black/6 mice after intra-peritoneal administration of the drug at a dose of 1 g/kg. The basic pharmacokinetic characteristics of carnosine were measured the in the blood and brain. The obtained concentration-time curve has a biexponential character. It is shown that the maximum concentration of carnosine in the blood plasma is Cmax = 1081.75 ± 124.24 μg/mL and it is achieved in a time interval of Tmax = 0.25 h. We showed that i.p. administration of exogenous carnosine could significantly increase the concentration of that substance in the brain. Tissue availability of dipeptide carnosine for brain tissue is relatively good and constitutes 59% from the total amount of blood carnosine. It was found that the maximum concentration of carnosine in the brain occurs at the sixth hour after i.p. administration when the concentration of drug in the blood is minimal.

Abstract
The efficiency of mexidant therapy in patients with Parkinson's disease (PD) has been evaluated. The study included 49 patients aged 58-65 with a trembling-rigid and trembling forms of PD at an disease duration of 6.5 +/- 3.8 years. All patients were treated with levadopa-containing drugs, dopamine receptor agonists and/or amantadine. In addition, 27 patients received mexidant at a dose of 200 mg/day (i.v.) for the first 10 days, followed by intramuscular injections of 100 mg (twice a day) for 10 days. The dynamics of symptoms in the group of patients receiving mexidat showed that the inclusion of this drug into the therapeutic regime significantly decreased the degree of levadopa therapy side effects. Mexidant reduced the oxidative damages of blood plasma lipoproteins by neutralizing the growth of lipid hydroperoxide and increased the endogenous antioxidant status. The presented data show that mexidant enhances the efficiency of PD therapy.

Abstract
Carnosine is a neuroprotective dipeptide consisting of beta-alanine and L-histidine. It demonstrates a number of useful features, including stimulation of brain and muscle microcirculation and a rejuvenating effect on cultured cells. Its activity is based on its antioxidant and antiglycating action that, in addition to heavy metal chelation and pH-buffering ability, makes carnosine an essential factor for preventing neurodegeneration and accumulation of senile features. Recently, carnosine was successfully used to treat patients after brain stroke or patients with Parkinson disease. We conclude that carnosine can be recommended for patients under oxidative stress as a natural remedy having high efficiency and no side effects.

Abstract
In our investigation, we describe the complex model of brain oxidative stress consisted of combination of experimental brain ischemia and energy metabolism violation induced by irreversible inhibitor of mitochondrial succi-nate dehydrogenase, 3-nitropropionate (3-NPA). 3-NPA causes selective degeneration of striatum neurons, which is extremely sensitive to energy deficit. This complex model allows revealing not only biochemical but also neurological symptoms in experimental animals that permits proper estimation of protective effect of different drugs on animal status. Combination of global ischemia induced by 3-vessel occlusion of major arteries supplys rat brain and subsequent 5-day reperfusion with intraperitoneal injection of 3-nitropropionic acid induces vigorous oxidative stress in brain tissues accompanied by evident neurological symptoms in Wistar rats. Such a combination of damaging factors may be considered as a new complex experimental model of brain oxidative stress permitting the evaluation of neuroprotective effect of potential therapeutic agents. Using this model, protective effect of neuropeptide carnosine was demonstrated which is in agreement with previous data.

Abstract
AIM To evaluate the efficiency of the rehabilitation in patients with obstructive pulmonary disease (COPD) and occupational bronchitis (OB) and the disabled due to these diseases, which was based on the authors' developed procedure and criteria for evaluating the efficiency of rehabilitative measures. MATERIALS AND METHODS The efficiency of implementation of 55 individual rehabilitation programs (RP) elaborated by the Medicosocial Examination Bureau for the disabled due to COPD and OB was evaluated. RESULTS The authors have determined qualitative criteria for evaluating the efficiency of rehabilitation: the extent to which the recommended rehabilitation measures being implemented, the trend in the magnitude of various vital activity categories and social inadequacy and in the disability group on regular examination, the results of implementation of some parts of an individual RP, the conformity of the achieved results to the rehabilitation potential of a disabled patient. The evaluation procedure supposes a unified quantitative gradation of each criterion. Overall, rehabilitation is more effective in COPD than in OB. CONCLUSION The developed criteria and procedures for evaluating the efficiency of rehabilitation in patients with COPD and OB show a great informative value and practical content richness, which permits one to make corrections into the rehabilitation process. Functional impairments, the degree of vital activity restrictions and social inadequacy, as well as the rehabilitation potential and rehabilitation prognosis are concomitantly evaluated, which allows minor changes to be assessed in the clinical, personality, and social status of a patient.

Abstract
The results of research of camosine as an antioxidative system corrector in conditions of oxidative stress caused by the action of damaging factors (y-rays, overcooling, hypobaric hypoxia, brain ischemia, neurotoxin impact) are summarized in the present review. The effects of carnosine are characterized not only at the level of the whole organism but also in "in vitro" models with use of a whole series of enzymatic systems. The results of the experiments conducted displayed the ability of carnosine to protect animals from oxidative stress based on the combination of direct antioxidative effects and a modulation of enzymes' activities which participate in controlling of reactive oxygen species level in tissues.

Abstract
Epithalamine produces a dose-dependent antioxidant effect in patients in the early stage of diabetic retinopathy (DR). Retinalamine normalizes the parameters of local hemostatic potential only under the conditions of completely restored antioxidant activity and lipid hydroperoxide level. Combined administration of epithalamine and retinalamine is recommended for correcting pathological changes of the hemostatic and antioxidant potential and for preventing the blood vessel damage in patients in the early stage of DR.

Abstract
A comparative analysis of the antioxidant activity of a series of pharmacological compounds was performed in vitro using Fe2+ induced chemiluminescence of lipoproteins. With respect to the protective action against lipoprotein oxidation, the compounds studied can be arranged in the following order: trolox > carnosine > emoxypine > L-carnitine = mildronate. The results show good prospects for using the proposed chemiluminescent technique for evaluating the antioxidant activity of pharmaceuticals.

Abstract
The antioxidant properties of mildronate and a structurally close compound L-carnitine were studied under clinical conditions during the therapy of patients with acute lacunar stroke and discirculatory encephalopathy (DEP) on the background of diabetes mellitus, respectively. Administered in addition to the base course of therapy, both mildronate (in a daily dose of 500 mg) and L-carnitine (2 mg) increased the resistance of blood serum lipoproteins with respect to peroxidation. It was concluded that the drugs possess antioxidant activity and offer protection against lipid peroxidation. L-carnitine acute produced a significant hypoglycemic action and made possible an almost twofold (42%) decrease in the dose of hypoglycemic drugs. The administration of L-carnitine also improved both abstract and concrete thinking and memory function in DEP patients. The results allowed mildronate and L-carnitine to be included in the complex therapy of patients with cerebrovascular diseases.

Abstract
Natural hydrophilic antioxidant carnosine protects cerebral cytosolic Cu,Zn-superoxide dismutase (SOD) under conditions of oxidative stress in various in vivo models: short-term hypobaric hypoxia in rats and accumulation of age-related changes in senescence-accelerated mice (SAMP). Administration of carnosine preventing Cu,Zn-SOD inactivation reduced mortality in rats and prolonged average life span in SAMP-mice.

Abstract
Significant decrease in the level of lipid antioxidants (measured from the kinetics of the induced chemiluminescence in brain homogenate) and of the hydrophilic antioxidant carnosine as well was observed in the brain of 14-16-month-old mice of SAMP1 line, which is characterized by accelerated accumulation of senile features, in comparison with the control line SAMR1. In the brain of SAMP1 animals the activity of cytosolic Cu/Zn-containing superoxide dismutase (SOD) was reduced, while the activity of membrane-bound Mn-SOD was at an extremely low level. The activity of glutathione-dependent enzymes (glutathione peroxidase, glutathione reductase, and glutathione transferase) did not differ in the brain of SAMP1 and SAMR1 animals, and catalase activity was similarly low in both cases. At the same time, excess concentration of excitotoxic compounds, significantly exceeding that for the control line, was determined in the brain and blood of SAMP1 animals. The activity of glutathione enzymes in liver and heart as well as the activity of cytosolic Cu/Zn-SOD in liver did not differ in the two studied lines, while the activity of erythrocyte glutathione peroxidase was slightly increased, and the activity of liver catalase and erythrocyte Cu/Zn-SOD was significantly decreased for SAMP1 compared with SAMR1. The results demonstrate that the accelerated ageing of SAMP1 animals is connected to a significant extent with the decreased efficiency of the systems utilizing reactive oxygen species (ROS) in tissues.

Abstract
Lipid peroxidation (LP) was analysed in the blood and atherogenic lipoproteins of 36 patients with ischemic stroke in the internal carotid arteries at the acute stage (1, 7 and 21 days). During 1-7 days 22 patients (group 1) were treated with haemocorrecting drugs (rheopolyglucin, euphyllin, aspirin, curantyl, trental) and 14 patients (group 2) were treated with vasoactive and metabolic drugs (cavinton, complamin, actovegin). On days 8-21 all the patients received the same treatment: pyracetam and essential. Before the treatment both activation of LP and exhaustion of endogenic antioxidant background were observed in blood samples of all the patients. Significant changes of LP parameters were observed in group 1 up to day 7, but they reached the basic level on the 21 day. No significant changes were observed in group 2. Thus, haemocorrecting drugs had some antioxidant effects, but to provide a steady antioxidant effect it is necessary to use special antioxidants.

Abstract
Lipid peroxidation was studied in the brain of Mongolian gerbils under conditions of complete ischemia followed by recirculation in the left hemisphere without recirculation in the right hemisphere. Thiobarbituric acid reactive products and the intensity of Fe2+-induced chemiluminescence were determined. The content of lipid peroxidation products in the brain tissue was increased not only under conditions of recirculation, but also at the ischemia stage during the limited access of oxygen. Thus, the destructive effect of free radicals may occur even during the early stage of ischemic injury of the brain.

Abstract
In the action mode of carnitine derivatives, the leading role is played by lipid transport inside the cell. Bearing in mind the important role of lipid peroxidation in lipid metabolism in the body and broad-range indications for use of carnitine derivatives in medical practice, it was decided to investigate the influence of carnitine derivatives on lipid peroxidation (LPO) in vitro to have a better understanding of the action mode of these drugs, as carnitine, according to the reported data, may affect certain LPO parameters in vivo.

Abstract
Musk-rats were infected simultaneously and at three-day interval with tularemia and Omsk hemorrhagic fever (OHF); the course of this mixed infection under the mentioned conditions were studied. Virological, microbiological and morphological data indicated that infection of musk-rats with OHF and tularemia caused development of mixed infection in them. A more severe course of mixed infection was associated with enhanced vascular affections caused by the action of the OHF virus. An inhibition of tularemia caused by the OHF development was noted in the course of mixed infection.
