Abstract
We studied the influence of extracellular vesicles from the follicular fluid of a young donor on gene expression (MKI67, MYBL2, CCNB1, CCND1, CCNE1, CALM2, BAX, NDRG1, TP53I3, VEGF, VCAN, HAS2, CTSL2, PIBF1, RPL37, PFKP, GPX3, and AQP3) in embryos of women of different ages. According to nanoparticle tracking analysis data, the concentration of extracellular vesicles was 3.75±0.47×1011 particles/ml and the mean particle size was 138.78±9.90 nm. During co-culturing of the follicular fluid extracellular vesicles with blastocysts of young women, we observed significantly increased expression of mRNA for genes CTSL2, CCND1, CCNE1, VEGF and reduced expression of BAX gene mRNA in comparison with embryos in women of late reproductive age. We hypothesized that addition of extracellular vesicles of the oocyte follicular fluid from a young donor to the culture medium of embryos could slow down apoptosis process typical of blastocyst cells in women above 36 years.

Abstract
We studied the effect of 2-h inhalation of argon-oxygen mixture (Ar 70%/O2 30%) after photochemically induced stroke and on days 2 and 3 after stroke modeling on the severity of neurological deficit and brain damage (by MRI data) in Wistar rats. Neurological deficit was assessed within 14 days using the limb placement test. MRI and histological study of the brain with an assessment of the size of damage were performed on day 14 after ischemia. Significant differences were obtained in limb placement scores on days 3, 7, and 14, as well as in the volume of ischemic focus by MRI in comparison with the control (ischemia+N2 70%/O2 30%). Inhalation of argon-oxygen mixture for 2 h a day over 3 days after photoinduced stroke decreased the volume of brain damage by 2 times and reduced the severity of neurological deficit.

Abstract
Sequestosome-1 (SQSTM1/p62) is one of the most important multifunctional proteins, which is necessary to maintain mitochondrial stability by eliminating damaged mitochondria through mitophagy. We studied the influence of age and diet on the expression of the p62 gene in the femoral and abdominal muscles of rats, as well as the integrity of some mitochondrial components. In the femoral muscles of 24-month-old rats receiving restricted ration, the expression of the p62 gene increased. We assume that activation of mitophagy contributed to a decrease in the levels of oxidative damage to mitochondrial DNA and LPO intensity in the femoral muscles of 24-month-old rats.

Abstract
We studied the effect of intranasal administration of neural stem cell (NSC)-derived exosomes on behavior and cognitive functions of mice in the late period after head irradiation in a dose of 8 Gy. The used exosomes had specific markers (CD9+/CD63+, 99.5%; TSG101+, 98.4%) and mean size 105.7±8.8 nm according to dynamic light scattering data and 119.0±12.4 nm according to nanoparticle tracking analysis (NTA). Exosome suspension (2×1012 particles/ml according to NTA measurements) was administered intranasally for 4 weeks starting from 48 h after irradiation in a volume of 5 μl/nostril (2×1010 exosomes/mouse). It was shown that intranasal administration of mouse NSC-derived exosomes prevented delayed radiation-induced behavioral changes and recognition memory impairments in mice after head irradiation.

Abstract
This article describes the experience of application of multipotent mesenchymal stromal cells in the complex therapy of severe recurrent cholangitis in 2 children with biliary atresia after Kasai surgery. In both children, hepatic cellular insufficiency and portal hypertension developed against the background of long-term inflammatory process poorly controlled by standard therapy, which was the indication for liver transplantation. During the course of mesenchymal stromal cells therapy, the relief of the inflammatory process and functional recovery of the liver were achieved. At the time of preparing the article, the follow-up of two children since the start of multipotent mesenchymal stromal cell therapy was 3 years 9 months and 2 years 6 months. No recurrence of cholangitis was observed in the patients during the follow-up period, the liver function was preserved. There are no indications for liver transplantation at this moment. Thus, despite the fact that the mechanisms of therapeutic action of multipotent mesenchymal stromal cells in biliary atresia require further investigation, we obtained promising results suggesting the possibility of using mesenchymal stromal cells in the treatment of postoperative complications in children with biliary atresia.

Abstract
The prognosis in neonatal hypoxic ischemic encephalopathy (HIE) depends on early differential diagnosis for justified administration of emergency therapeutic hypothermia. The moment of therapy initiation directly affects the long-term neurological outcome: the earlier the commencement, the better the prognosis. This review analyzes recent advances in systems biology that facilitate early differential diagnosis of HIE as a pivotal complement to clinical indicators. We discuss the possibilities of clinical translation for proteomic, metabolomic and extracellular vesicle patterns characteristic of HIE and correlations with severity and prognosis. Identification and use of selective biomarkers of brain damage in neonates during the first hours of life is hindered by systemic effects of hypoxia. Chromatography– mass spectrometry blood tests allow analyzing hundreds and thousands of metabolites in a small biological sample to identify characteristic signatures of brain damage. Clinical use of advanced analytical techniques will facilitate the accurate and timely diagnosis of HIE for enhanced management.

Abstract
We studied the effect of extracellular vesicles of the follicular fluid on morphofunctional characteristics of human spermatozoa using CASA (computer-assisted sperm analysis) analytical system. The vesicles were obtained by sequential centrifugation at different rotational speeds and frozen at -80°C in the Sydney IVF Gamete Buffer medium. The sperm fraction was isolated from the seminal fluid of 21 patients aged 27-36 years by differential centrifugation in a density gradient. The precipitate was suspended in Sydney IVF Gamete Buffer to a concentration of 106/ml and incubated with vesicles (1:2) at 37°C in a CO2 incubator for 30 min and 1 h. Sperm fraction incubated without vesicles served as the control. After incubation, some sperm samples were centrifuged at 700g for 5 min and fixed in 2.5% glutaraldehyde in 0.1 M buffer for transmission electron microscopy. After 30-min and 1-h incubation, the progressive and total sperm motility improved, the curvilinear and linear velocity of spermatozoa did not change significantly. Incubation with vesicles significantly changed the trajectory of sperm movement, which can attest to an increase in their hyperactivation and, probably, fertilizing capacity. Analysis of the effect of extracellular vesicles of follicular fluid on sperm motility will help to improve the effectiveness of assisted reproductive technology programs with male infertility factor by improving sperm characteristics in patients with asthenozoospermia and increasing the fertilizing ability of the sperm.

Abstract
BACKGROUND The rate of cesarean deliveries is steadily growing worldwide as a result of increasing maternal age at first delivery. Ensuring optimal recovery after surgery, specifically the development of a functionally competent uterine scar to facilitate vaginal birth after a cesarean delivery (VBAC), is one of the challenges in modern obstetrics. Extracellular microvesicles (EMVs) are secreted by multiple cell types and act as mediators of intercellular interaction during tissue reparation. The immunomodulatory and regenerative effects of EMVs of mesenchymal stromal cells (MSCs) have been studied shown in pre-clinical studies. AIM OF THE STUDY To evaluate the safety profile of EMVs of mesenchymal stromal placental cells (MSPCs) injected during the cesarean delivery and the impact of this pilot approach on post-surgery recovery. MATERIALS AND METHODS This pilot study included 53 women undergoing cesarean delivery with (n = 23) or without (n = 30) an injection of 500 µl of MSC EMVs after closing the uterine incision with a single continuous Vicryl suture. RESULTS All study participants had uncomplicated post-surgery period. The mean inpatient stay duration in women receiving the EMV injection was 4.26 ± 0.09 days vs. 5.33 ± 0.38 in the control group (p<.05). There were no postpartum inflammatory complications in the study group compared with two cases (6.7%) by postpartum endometritis/myometrial infection and one case (3.3%) of lochiometra in the control group. SUMMARY Intra-surgery injection of MSC EMVs was well-tolerated and associated with a lower rate of infectious post-partum complications in women undergoing cesarean delivery.

Abstract
Appending lipophilic cations to small molecules has been widely used to produce mitochondria-targeted compounds with specific activities. In this work, we obtained a series of derivatives of the well-known fluorescent dye 7-nitrobenzo-2-oxa-1,3-diazole (NBD). According to the previous data [Denisov et al. (2014) Bioelectrochemistry, 98, 30-38], alkyl derivatives of NBD can uncouple isolated mitochondria at concentration of tens of micromoles despite a high pKa value (~11) of the dissociating group. Here, a number of triphenylphosphonium (TPP) derivatives linked to NBD via hydrocarbon spacers of varying length (C5, C8, C10, and C12) were synthesized (mitoNBD analogues), which accumulated in the mitochondria in an energy-dependent manner. NBD-C10-TPP (C10-mitoNBD) acted as a protonophore in artificial lipid membranes (liposomes) and uncoupled isolated mitochondria at micromolar concentrations, while the derivative with a shorter linker (NBD-C5-TPP, or C5-mitoNBD) exhibited no such activities. In accordance with this data, C10-mitoNBD was significantly more efficient than C5-mitoNBD in suppressing the growth of Bacillus subtilis. C10-mitoNBD and C12-mitoNBD demonstrated the highest antibacterial activity among the investigated analogues. C10-mitoNBD also exhibited the neuroprotective effect in the rat model of traumatic brain injury.

Abstract
The mechanism of oxidative phosphorylation and its regulation remain one of the main problems of bioenergetics. Efficiency of the mitochondrial energization is determined by the relationship between the rate of generation of electrochemical potential of hydrogen ions and the rate of its expenditure on the synthesis of ATP and the use of ATP in endergonic reactions. Uncoupling (partial or complete), which occurs in the process of uncontrolled and controlled leakage of ions through the inner mitochondrial membrane, on the one hand leads to the decrease in the relative synthesis of ATP, and on the other, being consistent with the law of conservation of energy, leads to the formation of heat, generation of which is an essential function of the organism. In addition to increased thermogenesis, the increase of non-phosphorylating oxidation of various substrates is accompanied by the decrease in transmembrane potential, production of reactive oxygen species, and activation of oxygen consumption, water and carbon dioxide production, increase in the level of intracellular ADP and acidification of the cytosol. In this analysis, each of these factors will be considered separately for its role in regulating metabolism.

Abstract
Epidermolysis bullosa is a severe hereditary disease caused by mutations in genes encoding cutaneous basement membrane proteins. These mutations lead to dermal-epidermal junction failure and, as a result, to disturbances in the morphological integrity of the skin. Clinically, it manifests in the formation of blisters on the skin or mucosa that in some cases can turn into non-healing chronic wounds, which not only impairs patient's quality of life, but also is a live-threatening condition. Now, the main approaches in the treatment of epidermolysis bullosa are symptomatic therapy and palliative care, though they are little effective and are aimed at reducing the pain, but not to complete recovery. In light of this, the development of new treatment approaches aimed at correction of genetic defects is in progress. Various methods based on genetic engineering technologies, transplantation of autologous skin cells, progenitor skin cells, as well as hematopoietic and mesenchymal stem cells are studied. This review analyzes the pathogenetic methods developed for epidermolysis bullosa treatment based on the latest achievements of molecular genetics and cellular technologies, and discusses the prospects for the use of these technologies for the therapy of epidermolysis bullosa.

Abstract
We studied the development of acute kidney injury and animal death in the model of combined injury caused by kidney ischemia/reperfusion with simultaneous systemic administration of mitochondria. It was found that intraperitoneal injection of isolated mitochondria led to the appearance of mitochondrial DNA in the peripheral blood that could activate innate immunity. After administration of mitochondria, as well as after renal ischemia/reperfusion, proinflammatory changes were observed, primarily leukocytosis and granulocytosis. The combination of ischemia/reperfusion with injection of mitochondria caused a sharp increase in animal death, which may indicate a direct link between activation of TLR-signaling and high mortality of patients with combined injuries and multiple-organ failure in intensive care units. Treatment with mitochondria-targeted antioxidant increased animal survival, which indicated the participation of mitochondrial ROS in the development of systemic inflammatory response and death caused by acute renal failure.

Abstract
Light luminescent microscopy was used to study the distribution of extracellular microvesicles with PKH26-stained membranes secreted by placenta-derived mesenchymal stromal cells in the uterine tissues at different terms after injections to intact rats and after abdominal delivery (a model of cesarian section). Microvesicles migrated through the uterine tissues and were detected for at least 8 days after injection. In some cases, microvesicles were more numerous in the uterus after cesarian section modeling, which can be related to blockade of microcirculation and lymph flow due to inflammation accompanying surgical intervention. The content of microvesicles in the uterine tissues gradually declined due to macrophage phagocytosis and, probably, due to their migration into the vascular bed. Despite their size, properly stained extracellular microvesicles can be detected by light microscopy in tissues after injections.

Abstract
Autophagy plays an important role in the pathogenesis of acute kidney injury (AKI). Although autophagy activation was shown to be associated with an increased lifespan and beneficial effects in various pathologies, the impact of autophagy activators, particularly, rapamycin and its analogues on AKI remains obscure. In our study, we explored the effects of rapamycin treatment in in vivo and in vitro models of ischemic and cisplatin-induced AKI. The impact of rapamycin on the kidney function after renal ischemia/reperfusion (I/R) or exposure to the nephrotoxic agent cisplatin was assessed by quantifying blood urea nitrogen and serum creatinine and evaluating the content of neutrophil gelatinase-associated lipocalin, a novel biomarker of AKI. In vitro experiments were performed on the primary culture of renal tubular cells (RTCs) that were subjected to oxygen-glucose deprivation (OGD) or incubated with cisplatin under various rapamycin treatment protocols. Cell viability and proliferation were estimated by the MTT assay and real-time cell analysis using an RTCA iCELLigence system. Although rapamycin inhibited mTOR (mammalian target of rapamycin) signaling, it failed to enhance the autophagy and to ameliorate the severity of AKI caused by ischemia or cisplatin-induced nephrotoxicity. Experiments with RTCs demonstrated that rapamycin exhibited the anti-proliferative effect in primary RTCs cultures but did not protect renal cells exposed to OGD or cisplatin. Our study revealed for the first time that the mTOR inhibitor rapamycin did not prevent AKI caused by renal I/R or cisplatin-induced nephrotoxicity and, therefore, cannot be considered as an ideal mimetic of the autophagy-associated nephroprotective mechanisms (e.g., those induced by caloric restriction), as it had been suggested earlier. The protective action of such approaches like caloric restriction might not be limited to mTOR inhibition and can proceed through more complex mechanisms involving alternative autophagy-related targets. Thus, the use of rapamycin and its analogues for the treatment of various AKI forms requires further studies in order to understand potential protective or adverse effects of these compounds in different contexts.

Abstract
Traumatic brain injury is one of the leading causes of disability among the working-age population worldwide. Despite attempts to develop neuroprotective therapeutic approaches, including pharmacological or cellular technologies, significant advances in brain regeneration have not yet been achieved. Development of silk fibroin-based biomaterials represents a new frontier in neuroregenerative therapies after brain injury. In this study, we estimated the short and long-term effects of silk fibroin scaffold transplantation on traumatic brain injury and biocompatibility of this biomaterial within rat neuro-vascular cells. Silk fibroin microparticles were injected into a brain damage area 1 day after the injury. Silk fibroin affords neuroprotection as judged by diminished brain damage and recovery of long-term neurological functions. We did not detect considerable toxicity to neuro-vascular cells cultured on fibroin/fibroin-gelatin microparticles in vitro. Cultivation of primary cell cultures of neurons and astrocytes on silk fibroin matrices demonstrated their higher viability under oxygen-glucose deprivation compared to 2D conditions on plastic plates. Thus, we conclude that scaffolds based on silk fibroin can become the basis for the creation of constructs aimed to treat brain regeneration after injury.

Abstract
Oxidative kidney injury was compared in newborn and adult rats under conditions of ischemia/reperfusion and in experimental model of systemic inflammation induced by endotoxin (LPS of bacterial cell wall) administration. Oxidative stress in the kidney accompanied both experimental models, but despite similar oxidative tissue damage, kidney dysfunction in neonates was less pronounced than in adult animals. It was found that neonatal kidney has a more potent regenerative potential with higher level of cell proliferation than adult kidney, where the level proliferating cell antigen (PCNA) increased only on day 2 after ischemia/reperfusion. The pathological process in the neonatal kidney developed against the background of active cell proliferation, and, as a result, proliferating cells could almost immediately replace the damaged structures. In the adult kidney, regeneration of the renal tissue was activated only after significant loss of functional nephrons and impairment of renal function.

Abstract
Remote ischemic preconditioning of hind limbs (RIPC) is an effective method for preventing brain injury resulting from ischemia. However, in numerous studies RIPC has been used on the background of administered anesthetics, which also could exhibit neuroprotective properties. Therefore, investigation of the signaling pathways triggered by RIPC and the effect of anesthetics is important. In this study, we explored the effect of anesthetics (chloral hydrate and Zoletil) on the ability of RIPC to protect the brain from injury caused by ischemia and reperfusion. We found that RIPC without anesthesia resulted in statistically significant decrease in neurological deficit 24 h after ischemia, but did not affect the volume of brain injury. Administration of chloral hydrate or Zoletil one day prior to brain ischemia produced a preconditioning effect by their own, decreasing the degree of neurological deficit and lowering the volume of infarct with the use of Zoletil. The protective effects observed after RIPC with chloral hydrate or Zoletil were similar to those observed when only the respective anesthetic was used. RIPC was accompanied by significant increase in the level of brain proteins associated with the induction of ischemic tolerance such as pGSK-3β, BDNF, and HSP70. However, Zoletil did not affect the level of these proteins 24 h after injection, and chloral hydrate caused increase of only pGSK-3β. We conclude that RIPC, chloral hydrate, and Zoletil produce a significant neuroprotective effect, but the simultaneous use of anesthetics with RIPC does not enhance the degree of neuroprotection.

Abstract
We studied the neuroprotective potential of multipotent mesenchymal stromal cells in traumatic brain injury and the effect of inflammatory preconditioning on neuroprotective properties of stem cells under in vitro conditions. To this end, the effects of cell incubation with LPS or their co-culturing with leukocytes on production of cytokines IL-1α, IL-6, TNFα, and MMP-2 and MMP-9 by these cells were evaluated. Culturing under conditions simulating inflammation increased the production of all these factors by multipotent mesenchymal stromal cells. However, acquisition of the inflammatory phenotype by stromal cells did not reduce their therapeutic effectiveness in traumatic brain injury. Moreover, in some variants of inflammatory preconditioning, multipotent mesenchymal stromal cells exhibited more pronounced neuroprotective properties reducing the volume of brain lesion and promoting recovery of neurological functions after traumatic brain injury.

Abstract
One of the most important pathological consequences of renal ischemia/reperfusion (I/R) is kidney malfunctioning. I/R leads to oxidative stress, which affects not only nephron cells but also cells of the vascular wall, especially endothelium, resulting in its damage. Assessment of endothelial damage, its role in pathological changes in organ functioning, and approaches to normalization of endothelial and renal functions are vital problems that need to be resolved. The goal of this study was to examine functional and morphological impairments occurring in the endothelium of renal vessels after I/R and to explore the possibility of alleviation of the severity of these changes using mitochondria-targeted antioxidant 10-(6'-plastoquinonyl)decylrhodamine 19 (SkQR1). Here we demonstrate that 40-min ischemia with 10-min reperfusion results in a profound change in the structure of endothelial cells mitochondria, accompanied by vasoconstriction of renal blood vessels, reduced renal blood flow, and increased number of endothelial cells circulating in the blood. Permeability of the kidney vascular wall increased 48 h after I/R. Injection of SkQR1 improves recovery of renal blood flow and reduces vascular resistance of the kidney in the first minutes of reperfusion; it also reduces the severity of renal insufficiency and normalizes permeability of renal endothelium 48 h after I/R. In in vitro experiments, SkQR1 provided protection of endothelial cells from death provoked by oxygen-glucose deprivation. On the other hand, an inhibitor of NO-synthases, L-nitroarginine, abolished the positive effects of SkQR1 on hemodynamics and protection from renal failure. Thus, dysfunction and death of endothelial cells play an important role in the development of reperfusion injury of renal tissues. Our results indicate that the major pathogenic factors in the endothelial damage are oxidative stress and mitochondrial damage within endothelial cells, while mitochondria-targeted antioxidants could be an effective tool for the protection of tissue from negative effects of ischemia.

Abstract
Mitochondria-targeted antioxidant SkQ1 did not increase the content of cytochromes P450 in livers of rats that were given SkQ1 in drinking water for 5 days in a dose (2.5 µmol per kg body weight) that exceeded 10 times the SkQ1 therapeutic dose. SkQ1 did not affect the levels of cytochrome P450 forms CYP1A2, CYP2B6, and CYP3A4 in monolayer cultures of freshly isolated human hepatocytes, while specific inducers of these forms (omeprazole, phenobarbital, and rifampicin, respectively) significantly increased expression of the cytochromes P450 under the same conditions. We conclude that therapeutic doses of SkQ1 do not induce cytochromes P450 in liver, and the absence of the inducing effect cannot be explained by poor availability of hepatocytes to SkQ1 in vivo.

Abstract
The question if mitochondria have some kind of immune system is not trivial. The basis for raising this question is the fact that bacteria, which are progenitors of mitochondria, do have an immune system. The CRISPR system in bacteria based on the principle of RNA interference serves as an organized mechanism for destroying alien nucleic acids, primarily those of viral origin. We have shown that mitochondria are also a target for viral attacks, probably due to a related organization of genomes in these organelles and bacteria. Bioinformatic analysis performed in this study has not given a clear answer if there is a CRISPR-like immune system in mitochondria. However, this does not preclude the possibility of mitochondrial immunity that can be difficult to decipher or that is based on some principles other than those of CRISPR.

Abstract
We studied the possibility of in vivo tracing of multipotent mesenchymal stromal cells labeled with a radiophermaceutic preparation based on metastable isotope Technetium-99m and injected to rats with modeled traumatic brain injury. Accumulation of labeled cells occurred primarily in the liver and lungs. The cells distribution in internal organs greatly varied depending on the administration route. Cell injection into the carotid artery led to their significant accumulation in the damaged brain hemisphere, while intravenous injection was followed by diffuse cell distribution in all brain structures. Scintigraphy data were confirmed by magnetic resonance imaging and histological staining of cells. Visualization of stem cells labeled with Technetium-99m-based preparation by scintigraphy is an objective and highly informative method allowing real-time in vivo cell tracing in the body.

Abstract
At first glance, biological differences between male and female sex seem obvious, but, in fact, they affect a vast number of deeper levels apart from reproductive function and related physiological features. Such differences affect all organizational levels including features of cell physiology and even functioning of separate organelles, which, among other things, account for such global processes as resistance to diseases and aging. Understanding of mechanisms underlying resistance of one of the sexes to pathological processes and aging will allow taking into consideration gender differences while developing drugs and therapeutic approaches, and it will provide an opportunity to reproduce and enhance such resistance in the more vulnerable gender. Here we review physiological as well as cellular and biological features of disease course including aging that are affected by gender and discuss potential mechanisms behind these processes. Such mechanisms include features of oxidative metabolism and mitochondrial functioning.

Abstract
Here, in addition to the previously coined term "mitobiota", we introduce the term "mitodiversity" for various phenotypic and genetic heterogeneities of mitochondria within the same cell or organ. Based on data on the mitochondrial transmembrane potential determined both in situ and in vitro under normal conditions and after organ ischemia/reperfusion, such heterogeneity is most evident under pathologic conditions. Herein, a part of the mitochondrial population with transmembrane potential typical of the normal state is sustained even under a pathological condition that, perhaps, underlies the development of ways of reversing pathology back to the normal state. The membrane potentials of isolated mitochondria were shown to directly correlate with the magnitude of side-scattered light depicting internal structure of mitochondria. We analyzed possible interpretations of data on mitochondrial membrane potential obtained using fluorescent probes. We suggest a possible mechanism underlying retention of fluorescent probes inside the cells and mitochondria.

Abstract
Recently described phenomenon of intercellular transfer of mitochondria attracts the attention of researchers in both fundamental science and translational medicine. In particular, the transfer of mitochondria results in the initiation of stem cell differentiation, in reprogramming of differentiated cells, and in the recovery of the lost mitochondrial function in recipient cells. However, the mechanisms of mitochondria transfer between cells and conditions inducing this phenomenon are studied insufficiently. It is still questionable whether this phenomenon exists in vivo. Moreover, it is unclear, how the transfer of mitochondria into somatic cells is affected by the ubiquitination system that, for example, is responsible for the elimination of "alien" mitochondria of the spermatozoon in the oocyte during fertilization. Studies on these processes can provide a powerful incentive for development of strategies for treatment of mitochondria-associated pathologies and give rise a new avenue for therapeutic approaches based on "mitochondrial transplantation".

Abstract
Here we studied the cytoprotective effect of lithium chloride and sodium valproate in the in vivo model of neonatal cerebral ischemia/hypoxia and analyzed the influence of these substances on the death of the major neurovascular unit components in experimental ischemia in vitro. Lithium chloride and sodium valproate effectively prevented death of neurons, astrocytes, and endothelial cells in the oxygen-glucose deprivation. This treatment protected the brain of newborn rats from ischemia/hypoxia injury. The results suggest that lithium and sodium valproate can be used for the treatment of neurodegenerative pathologies associated with hypoxia and ischemia in newborns.

Abstract
Structural organization of mitochondria reflects their functional status and largely is an index of the cell viability. The indirect parameter to assess the functional state of mitochondria and cells is the degree of fragmentation, i. e. a ratio of long or branched mitochondrial structures to rounded mitochondria. The critical need for such evaluations requires the creation of an approach, that allows on the basis of confocal images of mitochondria stained with a fluorescent probe, to create an integral picture of the three-dimensional organization of mitochondria. In the present study, we tested three approaches to analyze the structural architecture of mitochondria under norm and fission induced by oxidative stress. We have revealed that while the most informative way of analysis is a three-dimensional reconstruction based on series of confocal images taken in Z-dimension, however, with some limitations it is plausible to use more simple algorithms of analysis, including that one that uses unitary two-dimensional images. Further improvement of these methods of image analysis will allow more comprehensive analysis of mitochondrial architecture under norm and different pathological states. It may also provide quantification of a number of mitochondrial parameters determining morpho-functional state of mitochondria primarily their absolute and relative volumes and give additional information on three-dimensional organization of mitochondriome.

Abstract
It is known that the mechanisms of damage in the brain after stroke are regulated by combination of several types of cells, primarily of neurons, astrocytes, endothelium and microglia. Ischemic exposure disrupts the balance in the cellular composition of the brain; in the lesion, cells die by necrosis while in tissue surrounding ischemic zone the delayed induction of apoptosis occurs, and namely the ratio of death of different cells determines the clinical outcome of the disease. Thus, the assessment of death of various cell types of the neurovascular unit is an important part of fundamental studies of the mechanisms of brain damage and pre-clinical studies of potential neuroprotective drugs. In this line, we have conducted a comparative study of the two most often used methods: immunohistochemical staining of brain sections, allowing to determine the number and localization of specific cells in the tissue among other types of cells, and immunoblotting that detects specific proteins in the tissue homogenate. We have found that, depending on the type of cells, changes in their number and composition after stroke can be diffuse or localized, which imposes restrictions on the use of any method of estimation of the number of cells in brain tissue. In general, the most preferable is the use of immunohistochemistry, however, with certain limitations, immunoblotting can be used in estimating amounts of astroglia and microglia.

Abstract
The recent revival of old theories and setting them on modern scientific rails to a large extent are also relevant to mitochondrial science. Given the widespread belief that mitochondria are symbionts of ancient bacterial origin, the processes inherent to mitochondrial physiology can be revised based on their comparative analysis with possible involvement of bacteria. Such comparison combined with discussion of the role of microbiota in pathogenesis allows discussion of the role of "mitobiota" (we introduce this term) as the combination of different phenotypic manifestations of mitochondria in the organism reflecting pathological changes in the mitochondrial genome. When putting an equal sign between mitochondria and bacteria, we find similarity between the mitochondrial and bacterial theories of cancer. The presence of the term "bacterial infection" suggests "mitochondrial infection", and mitochondrial (oxidative) theory of aging can in some way be transformed into a "bacterial theory of aging". The possible existence of such processes and the data confirming their presence are discussed in this review. If such a comparison has the right to exist, the homeostasis of "mitobiota" is of not lesser physiological importance than homeostasis of microbiota, which has been so intensively discussed recently.

Abstract
The effect of SkQ1 (a mitochondria-targeted antioxidant) on the level of cytochromes P450 in rat liver was studied. It was found that administration of therapeutic dose of SkQ1 with drinking water for 5 days (250 nmol/kg of body weight per day) did not alter the level of cytochromes P450. Under the same conditions, the standard dose of phenobarbital used for the induction of cytochromes P450 caused the 2.7-fold increase in the content of these cytochromes. We conclude that therapeutic doses of SkQ1 do not induce cytochromes P450 in rats.

Abstract
We studied the influence of ischemia/reperfusion of the middle cerebral artery in the rat's brain on the deferred violation of cognitive functions of the brain which are similar to main symptoms observed in the development of Alzheimer's disease. Using 8-hose radial labyrinth we demonstrated that 6 months after incidence of cerebral ischemia a significant impairment of working memory and a decrease in animals the ability to learn are developed. 7 months after focal cerebral ischemia we could observe the accumulation of a mature amyloid peptide and hyperphosphorylated form of the Tau pro- tein in ipsilateral cerebral hemisphere and of the the beta-amyloid peptide precursor in the contralateral hemisphere. Thus, after an experimental stroke in the brain pathological chanres occur as those typical of Alzheimer's disease.

Abstract
It is generally accepted that mitochondrial production of reactive oxygen species is nonlinearly related to the value of the mitochondrial membrane potential with significant increment at values exceeding 150 mV. Due to this, high values of the membrane potential are highly dangerous, specifically under pathological conditions associated with oxidative stress. Mild uncoupling of oxidative phosphorylation is an approach to preventing hyperpolarization of the mitochondrial membrane. We confirmed data obtained earlier in our group that dodecylrhodamine 19 (C(12)R1) (a penetrating cation from SkQ family not possessing a plastoquinone group) has uncoupling properties, this fact making it highly potent for use in prevention of pathologies associated with oxidative stress induced by mitochondrial hyperpolarization. Further experiments showed that C(12)R1 provided nephroprotection under ischemia/reperfusion of the kidney as well as under rhabdomyolysis through diminishing of renal dysfunction manifested by elevated level of blood creatinine and urea. Similar nephroprotective properties were observed for low doses (275 nmol/kg) of the conventional uncoupler 2,4-dinitrophenol. Another penetrating cation that did not demonstrate protonophorous activity (SkQR4) had no effect on renal dysfunction. In experiments with induced ischemic stroke, C(12)R1 did not have any effect on the area of ischemic damage, but it significantly lowered neurological deficit. We conclude that beneficial effects of penetrating cation derivatives of rhodamine 19 in renal pathologies and brain ischemia may be at least partially explained by uncoupling of oxidation and phosphorylation.

Abstract
A protective effect of a mitochondria-targeted antioxidant, a cationic rhodamine derivative linked to a plastoquinone molecule (10-(6'-plastoquinonyl)decylrhodamine-19, SkQR1) was studied in the model of open focal trauma of rat brain sensorimotor cortex. It was found that daily intraperitoneal injections of SkQR1 (100 nmol/kg) for 4 days after the trauma improved performance in a test characterizing neurological deficit and decreased the volume of the damaged cortical area. Our results suggest that SkQR1 exhibits profound neuroprotective effect, which may be explained by its antioxidative activity.

Abstract
Mitochondrial medicine was established more than 50 years ago after discovery of the very first pathology caused by impaired mitochondria. Since then, more than 100 mitochondrial pathologies have been discovered. However, the number may be significantly higher if we interpret the term "mitochondrial medicine" more widely and include in these pathologies not only those determined by the genetic apparatus of the nucleus and mitochondria, but also acquired mitochondrial defects of non-genetic nature. Now the main problems of mitochondriology arise from methodology, this being due to studies of mitochondrial activities under different models and conditions that are far from the functioning of mitochondria in a cell, organ, or organism. Controversial behavior of mitochondria ("friends and foes") to some extent might be explained by their bacterial origin with possible preservation of "egoistic" features peculiar to bacteria. Apparently, for normal mitochondrial functioning it is essential to maintain homeostasis of a number of mitochondrial elements such as mitochondrial DNA structure, membrane potential, and the system of mitochondrial quality control. Abrogation of these elements can cause a number of pathologies that have become subjects of mitochondrial medicine. Some approaches to therapy of mitochondrial pathologies are discussed.

Abstract
Cardiovascular pathologies are the major causes of morbidity and mortality in the world. Cessation of the blood flow in large vessels, supplying tissues with oxygen and substrates, leads to ischemic conditions accompanied by unwanted shifts of oxidative metabolism and rise of the reactive oxygen species (ROS) generation. Small amounts of ROS are essential elements of the cell metabolism, however pathological elevation of ROS jeopardizes the survival of cells, organs and even organisms. Paradoxically, blood flow restoration during prolonged ischemia leads to oxidative stress that is often fatal for a live system. Oxygen paradox appears to be a limiting factor in clinical practice that intuitively seeks for immediate and complete restoration of a damaged blood flow. Mitochondrion is a major ROS source and a key element of pro-apoptotic signaling, however it is clear, that mitochondria are the main target for anti-ischemic treatment. In the present review we consider two ways of such anti-ischemic strategy, bringing ischemic tolerance to the organ through mitochondrial involvement, such as intrinsic, biological, or artificial, pharmacological adaptive systems (preconditioning). The latter is aimed to simulate elements and high efficiency of intrinsic protective system. The role of antioxidants in anti-ischemic therapy and their effects on preconditioning signaling are discussed in the review.

Abstract
The application of magnetic resonance imaging method showed that ischemia/hypoxia of the brain of neonatal rats made by the protocol suggested by Levine-Rice induces one-sided lesions in the areas of cerebral cortex, striatum and hippocampus. Unilateral ischemic injury leads to a long-term sensorimotor and behavioral distortions within 90-115 days after the operation which has been tested in animals by the battery of tests including Cylinder, Beam-walking, Staircase and Limb-placing test. Chosen battery of tests in combination with magnetic resonance imaging allows to reliably estimate the long-term sensorimotor recovery in adult animals suffered an injury in neonatal age.
