Inflammasomes are macromolecular complexes that contain many copies of receptors recognizing molecular patterns of pathogenic agents (PAMP) and damage-associated structures (DAMP), and also include molecules of adapter protein ASC and procaspase- 1. Activation of inflammasomes leads to the formation of active caspase-1 that, in turn, provides the maturation of pro-IL-1β and pro-IL-18 to IL-1β and IL-18. The latter cytokines play an important role in control of neuroinlfammation in the central nervous system contributing to the pathogenesis of a series of neurological, neurodegenerative and mental disorders. The review discusses the involvement of NLRP3 inflammasome and other their types in the development of the traumatic brain injury, ischemic and hemorrhagic stroke, brain tumors, CNS infections, Alzheimer’s and Parkinson’s diseases, epilepsy, amyotrophic lateral sclerosis, depressiver, and consequences of alcohol abuse. The elucidation of molecular mechanisms and signaling pathways controlled by inflammasomes will allow the development of new therapeutic measures for diseases, in which neuroinflammation plays a leading pathogenetic role.

To conduct a comparative analysis of the effectiveness of an improved imidazole derivative (2% clotrimazole cream) as part of complex therapy with standard treatment regimens for the development of bacterial vaginosis and vulvovaginal candidiasis. Materials and methods. The study included 90 women who had combinations of Atopobium vaginae, Gardnerella vaginalis and Candida krusei. These pathogens caused not only the development of an infectious process in the lower part of the urogenital tract, but also its complicated course. Results. The study showed that the use of the improved imidazole derivative (2% clotrimazole cream) could arrest the main symptoms of the disease after the first use. The drug is highly effective against difficult-to-cultivate pathogens of bacterial vaginosis and Candida non-albicans, and also does not adversely affect the amount of lactobacilli in vaginal biocenosis. Conclusion. The experience of using the improved imidazole derivative shows that the drug is no less effective in inflammatory diseases of the lower parts of the urogenital tract than its counterparts. Its purpose is appropriate in the complex therapy of complicated bacterial vaginosis and vulvovaginal candidiasis.

© 2018 Stolichnaya Izdatelskaya Kompaniya. All rights reserved. The key to successful treatment in patients with acute coronary syndrome is maximally early revascularization of the coronary arteries. Treatment of multifocal atherosclerosis with lesions of the coronary and peripheral arteries requires coordinated work of the multidisciplinary team of doctors. Critical ischemia of the lower limbs requires urgent revascularization in order to prevent limb amputation. However, it is not always possible to perform revascularization using specialists of the same profile – endovascular or surgical. The use of hybrid methods of treatment (surgical and endovascular) allows to significantly improve the prognosis in saving the limb. The article presents a clinical observation of successful multistep treatment of a patient with acute coronary syndrome in combination with critical ischemia of the lower limb. The first stage was performed by multiple stenting of the coronary arteries with bioabsorptive scaffolds; the second stage was the hybrid treatment – femoral-tibial bypass with simultaneous recanalization and angioplasty of the lower leg arteries with good postoperative and long-term outcome.

Published by Oriental Scientific Publishing Company © 2018. The study assessed stress and brux activity among dental students during exam (stress) and non-examination (non-stress) periods. The study was initiated as a single group design with the total number of participants 36 (25 females and 11 males). All the participants were examined twice (once in a stress period and once in a non-stress period) according to “Clinical Functional Analysis”, which includes questions about students’ medical and dental history, as well as muscle palpation results. Two «BruxCheckers» (BCs) were applied, one for the upper jaw, the other for the lower jaw, two times for examination and non-examination periods. After the use, the «BCs» were photographed according to the research protocol and the abraded facets area on «BCs» was calculated in square millimeters. The research showed that during a stress period students may have headaches, cramps and pain in shoulder and neck muscles. The research also revealed that during the stress situation the abraded area shifts from frontal teeth to chewing teeth and brux episodes can occur more frequently and with a higher load. Chewing teeth (premolars in our study) are more adapted and more useful for such a condition. Accordingly, our students shifted their brux behavior from teeth 33 and 31 to teeth 15 and 24. Therefore, exams are a strong stress factor for dental students. In turn, prolongated stress can be an indicator of risk factor and have a negative effect for health of the craniomandibular system.

The article covers the development of the problem of sudden cardiac death prevention with the implantable cardioverterdefibrillators from the moment of creation of these devices to our days. The current concept of primary prevention of sudden cardiac death, based on the severity of manifestation of heart failure and left ventricular dysfunction, is not effective enough. Its practical application is difficult because it requires mass application of implantable defibrillators, with low predictive accuracy of these criteria in terms of development of lifethreatening arrhythmias. The development of methods for visualizing the myocardium, allowing to assess the severity of myocardial fibrosis, as well as the possibilities of medical genetics, at the present stage, allows us to clarify indications for implantation of cardioverterdefibrillators and thereby significantly improve the concept of preventing sudden cardiac death with these instruments.

© 2018 Limited Liability Company KlinMed Consulting. All Rights Reserved. Purpose: to elucidate predictors of development of chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary artery thromboembolism (PTE). Material and methods. We included in this study 210 patients hospitalized with diagnosis of submassive and massive PTE from 2013 to 2017. In 1 to 3 years after initial hospitalization these patients were invited for control examination. According to results of this examination patients were divided into two groups: with (group 1, n=45) and without (group 2, n=165) signs of CTEPH. Severity of pulmonary artery vascular bed involvement was assessed by multislice computed tomography (MSCT) angiography and lung scintigraphy. For detection of thrombosis in the inferior vena cava system we used ultrasound angioscanning. Examination also included echocardiography. Results. In the process of mathematical analysis, the following risk factors for the development of CTEPH embolism were determined: duration of thrombotic history (group 1 - 13.70±2.05 days, group 2- 16.16±1.13 days, p=0.015), localization of venous thrombosis in the lower extremities (the most favorable - shin veins, popliteal, and common femoral veins, unfavorable - superficial femoral vein). The choice of the drug for thrombolytic and anticoagulant therapy: streptokinase and urokinase were significantly more effective than alteplase, rivaroxaban was superior to the combination of unfractionated or low molecular weight heparins with warfarin. Also, risk factors for the development of CTEPH were the initial degree of pulmonary hypertension and tricuspid insufficiency, as well as the positive dynamics of these indicators at the background of thrombolytic or anticoagulant therapy. Of concomitant diseases, significant risk factors for development of CTEPH were grade 3 hypertensive disease, diabetes mellitus, postinfarction cardiosclerosis. On the other hand, age, gender, degree of severity at the time of admission, presence of infarction pneumonia, surgical prevention of recurrent pulmonary embolism, number of pregnancies and deliveries, history of trauma and malignancies, cardiac arrhythmias produced no significant impact on the development of CTEPH.

© 2018 Russian Academy of Sciences. Wide circulation of HIV-infection/AIDS is a socially important problem for the majority of the countries of the world now. Against the background of the remaining high rates of infection spread beyond the borders of risk groups, a series of the negative phenomena aggravating an epidemiological situation on HIV-infection and other socially important diseases is observed (tuberculosis, hepatitises, etc.): depression of the general indicators of health of the population, urbanization, complicating of life rhythm, wide circulation of dependences on psychoactive agents, and, above all - serious transformation of institute of family, liberalization of sex behavior, of traditional family values. Now in representations of Russians the typical HIV-positive-a young childless and single man regardless of sexual orientation who is living in the large city, having an average special educations or being in process of its receiving whith level of income comparable to average one. The HIV-positive has been Infected as a result of a youth error (unprotected sexual contact or the intravenous use of drugs) and lives with this diagnosis several years, leads a risk-free life more often, at the same time usually hiding the diagnosis and separated from social communications. Existence of this diagnosis involves social trouble and the social not approved behavior, but if the disease affects the loved one, many Russians are potentially ready to give moral and psychological support (56%), financial support (including in purchase of drugs), the help in search of necessary experts and visit of the medical organizations (6,9%) and also to care for the HIV infected and their children (6%). According to authors, the widespread negative perception of people with "HIV-infection" diagnosis is in many respects caused by insufficient informing the population on HIV-infection/AIDS problems.

© 2018 Izdatel'stvo Meditsina. All rights reserved. NMDA receptor modulators are a new class of antidepressants with rapid onset of action and lasting antidepressant effect. These drugs increase BDNF level in CNS and adult hippocampal neurogenesis, which events are in common for both NMDA receptor modulators and classical antidepressants. However, unlike classical antidepressants, drugs of this new group produce no direct influence on the monoaminergic system, but regulate the neuroplasticity in the prefrontal cortex and hippocampus via modulation of the glutamatergic neurotransmission. Clinical tests of ketamine and rapastinel confirmed the rapid onset of action and the continuation of stable antidepressant effect (upon single administration per 7 days) for both usual and treatment-resistant forms of depression.

The purpose of the study was to determine effects of quercetin on protective capacity parameters in the experiment on rats fed a high fructose diet. Rats of the control group received a semi-synthetic (s/s) diet and water; animals from the P' experimental group-s/s diet and 20% fructose solution instead of drinking water; rats of the 2nd experimental group-s/s diet with quercetin (0.1% indiet) and 20% fructose solution instead of drinking water for 20 weeks. Parameters of antioxidant status [total antioxidant activity (AOA), the content of malondialdehyde (MDA) and lipids hydroperoxides, the level of reduced andoxidizedglutathione, activity of superoxide dismutase, catalase, glutathione peroxidase, paraoxonase-1, hemeoxygenase-1, NAD(P)H-quinone oxidoreductase], the activity of xenobiotic-metabolizing enzymes [CYP1A1, CYP1A2, CYP2B1, CYP3A, UDP-glucuronosyltransferase (UDP-GT) and glutathione transferase] were studied in plasma and liver of rats. Consumption of the high-fructose diet led to changes in some parameters: diminution of AOA in blood plasma, decrease of AOA and MDA level, unsedimentable activity of lysosomal enzymes, increase of the UDP-GT activity in liver. The inclusion of quercetin in the diet did not affect the studied parameters, except for a more pronounced decrease of the unsedimentable activity of lysosomal enzymes in rat liver. The results of the study indicated that there was no significant effect of quercetin on the protective capacity of rats at the initial stage of obesity caused by high-fructose diet.

Lutein and zeaxanthin are carotenoid pigments that affect the function of the visual analyzer. They selectively accumulate in the yellow spot of the retina, form macular pigment and determine the density of the retina macula. Lutein and zeaxanthin slow down the progression of age-related macular degeneration, a leading cause of senior-age blindness. The main food sources of non-vitamin carotenoids are green leafy vegetables, zucchini, pumpkin, green peas, broccoli. The aim of the study is a retrospective assessment of the levels and sources of alimentary intake of lutein and zeaxanthin in young people and research of the effect of lutein and zeaxanthin in the diet on macula density. A specially designed questionnaire was used to quantify the content of lutein and zeaxanthin in the diet, reflecting the amount of consumption of the main sources of these carotenoids on the day preceding the survey. A non-invasive non-contact method of optical coherence tomography of the retina was used to determine the density of the macula. The study involved 96 students of Sechenov University at the age of 21-27 years. The study found that only 6.25% of the respondents had daily intake of lutein and zeaxanthin of 6 mg or more, 8.33% had 4.6-5.9 mg, 8.33% had 3.0-4.5 mg, in 18.75% - 1.5-2.9 mg, in 45.83% <1.4 mg 12.5% of respondents didn't include sources of lutein and zeaxanthin in the diet. The more common sources of lutein and zeaxanthin in the diet were eggs and fresh tomatoes. Retinal density indices corresponded to the age standards in the majority of the examined. In 8.3% surveyed the thickness of the retina was decreased, and 4.2% had higher thickness of the retina in comparison with the standards. Significant differences in the Central subfield thickness in men and women were revealed. There was no dependence of the levels of lutein and zeaxanthin coming from food sources on the retina thickness indicators.

Abnormal mobility of the posterior membranous wall of the trachea and large bronchi is seen in many bronchopulmonary chronic inflammatory diseases. Currently, clear explanation of a mechanism of the expiratory tracheal stenosis (ETS) is absent. The advanced ETS is associated with severe ventilation abnormalities including asphyxia and syncope. The latter conditions are considered as indications for surgical treatment. Results of the surgical treatment are controversial and are not fully acceptable. For this reason, the surgical treatment for ETS is not routinely used and any successive case of such treatment is of great interest. Strict indications, such as life-threatening conditions or failure of optimal medical treatment, are required for surgical treatment of patients with tracheomalacia and ETS. Surgical treatment for tracheomalacia and ETS is contraindicated in the case of lobar bronchial lesion impeding stabilization the membranous part of the tracheobronchial tree.

The aim of the study was to assess the possibility of penetration of Escherichia coli bacteria into the dentinal tubules of the samples and determine the antimicrobial efficacy after 5 and 20 min exposition of 3% H2O2 (groups I and II) and 1 and 5 min exposition of 3% NaOCl (groups III and IV) for surface disinfection of bovine teeth. The samples were subjected to inoculation with E. coli suspension. The quality of disinfection was assessed with the three methods. The surface disinfection of samples proved to be effective only in groups II and IV. In the cultures of all dissolutions of dentinal chips suspensions in groups I, III and V there was a growth of E. coli in the form of a continuous pitch. In the group II a growth of Escherichia coli was revealed only in the initial dissolution in the quantity 1,8x101 CFU/ml, whereas in the group IV the growth was nil. Quantitative estimation of bacterial penetration using the method of maximum dissolutions revealed similar quantity of bacteria as in the group II as well as in the calculation of CFU. The application of 3% solution of H2O2 with the exposition of 20 minutes secures the qualitative surface disinfection of teeth without destruction of bacteria inside dental tubules and that allows to discover viable bacteria inside dentinal tubules.

The purpose of our study was to assess the efficiency of toothpaste 'Intensive strengthening of supersensitive teeth with nano-GAP' INNOVA and the suspension 'Liquid Enamel' INNOVA on the sensitivity of teeth with gingival recession. We examined 40 people aged 20-25 years. Each group consisted of 20 people: 10 women, 10 men. The first group (observations) used the paste and the suspension for 14 days, and the second group (comparisons) cleaned teeth only with a brush without a paste. Schiff aerial test was performed to assess the rate of hypersensitivity. As a result of the study, it was found that the combination of paste and liquid suspension with nano-hydroxyapatite for 14 days effectively reduced the hypersensitivity of the teeth with gingival recession that was shown by a statistically significant decrease in the Schiff index in the observation group. Thus, this combination is the method of choice in the treatment of hyperesthesia and can be used as an alternative substitute therapy.

For nine months, the mother’s heart works under conditions of daily additional load, which is necessary to ensure placental blood flow. In this regard, structural and functional adaptation of the heart develops in a healthy woman with a normal pregnancy. A pregnant woman with some heart diseases is less likely to adapt. That leads to greater susceptibility to stress resulting in pathological changes of pregnancy. In addition, each pregnancy may develop new heart diseases, which in some cases may be relatively innocent, but in others — fatal. In this regard echocardiography (EchoCG) is a necessary procedure for assessing a woman’s health status that needs before bearing a fetus, during and after pregnancy.

The study of the epidermis and derma histogenesis, including its epigenetic regulation, is an actively developing field of histology and embryology. The results of the study can elucidate the mechanisms of pathogenesis of some skin diseases of unknown etiology. Wnt signaling is a key regulator of the main morphogenetic processes — cell proliferation and differentiation. Downstream of Wnt signaling is carried out by canonical and non-canonical pathways. Impairments of Wnt signaling in prenatal and postnatal development lead to degenerative and tumor diseases of the skin and hair. Clinical manifestations of the prenatal disorders of skin development epigenetic regulation in the period may appear long after the birth. Identification of factors that disturb the regulation of morphogenetic processes is an important task for investigators. It was found out that activation of the mother’s immune system in the early pregnancy resulted in the development of transient alopecia in the offspring of mice. There was the correlation established between the disorders of epidermal and dermal histogenesis and alopecia as well as the development of regional dysmorphogenetic changes in the skin, which indicate the need to study the rates and features of skin development in various parts of the body.

Nerve damage is a common severe trauma caused by a complete or partial disruption of the integrity of the nerve trunk and appropriate dissociation of the CNS and denervated tissue. «Golden standard» in the treatment of extensive injuries of peripheral nerves is the use of autografts of nerve fibers, but when they are used, pathological disturbances appear in the donor zone and the results of surgical treatment are not always satisfactory. Currently, an alternative to the traditional method is the use of nerve conduits (conductors) for directed regeneration of axons. In this work, the results of the application of nerve conductors from various materials and with various biologically active components in preclinical and clinical studies, as well as conduits used in clinical practice, were analyzed. The efficiency of regeneration was compared, on the basis of the analysis the conductor most suitable for successful nerve regeneration was selected, including approaches for creating innervated tissue engineered constructs. In this work, we have collected research on nerve conductors from various materials with various prescribed properties using certain factors used to treat damage to the peripheral nervous system, showing all the advantages and disadvantages of their use, which makes it possible to develop and create a conduit that meets all the requirements of modern regenerative medicine.
