The method consists in exposure to ultrahigh frequency electromagnetic radiation, modulated by infralow frequencies with variable parameters. A specially designed programmer, setting up the parameters of exposure, is connected to the source of radiation. The zones of anatomical location of the red bone marrow of rats were exposed for 15 min to the amplitude-modulated electromagnetic radiation of ultrahigh frequency range. The parameters of exposure were determined in previous studies. The red bone marrow was collected from the sternum and head of the femur. The cellular composition of the red bone marrow was evaluated 1, 2, 3, and 6 days after the exposure. The optimal therapeutic mode of irradiation was then chosen, leading to stem cell activation with subsequent proliferation and differentiation into mature red bone marrow cells.

Introduction: Heart rate (HR) reduction is an integral part of antianginal therapy, but many patients do not reach the guideline-recommended target of less than 60 bpm despite high use of beta-blockers (BB). Failure to uptitrate BB doses may be partly to blame. To explore other options for lowering HR and improving angina control, CONTROL-2 was initiated to compare the efficacy and tolerability of the combination of BBs with ivabradine versus uptitration of BBs to maximal tolerated dose, in patients with stable angina. Methods: This multicenter, open, randomized study included 1104 patients with Canadian Cardiovascular Society (CCS) class II or III stable angina, in sinus rhythm, and on background stable treatment with non-maximal recommended doses of BBs. Consecutive patients were allocated to ivabradine + BB or BB uptitration in a 4:1 ratio. Results: At the end of the study (week 16), addition of ivabradine to BB treatment and BB uptitration resulted in reduction in HR (61 ± 6 vs. 63 ± 8 bpm; p = 0.001). At week 16, significantly more patients on ivabradine + BB were in CCS class I than with BB uptitration (37.1% vs. 28%; p = 0.017) and significantly more patients were angina-free (50.6% vs. 34.2%; p < 0.001). Patient health status based on the visual analogue scale (VAS) was also better in the ivabradine + BB group. Adverse events (AEs) were significantly more common with BB uptitration than with the ivabradine + BB combination (18.4% vs. 9.4%, p < 0.001). Conclusion: In patients with stable angina, combination therapy with ivabradine + BB demonstrated good tolerability, safety, and more pronounced clinical improvement, compared to BB uptitration.

The review summarizes information on cyclopropane as an independent pharmacophore group and as a fragment for modification of pharmacological activity level of medicines used in practice. The advantages of a cyclopropane fragment over its bioisosteres are that, on the one hand, this fragment imposes conformational rigidity on the molecules of physiologically active compounds and, on the other hand, the replacement of acyclic terminal and “linker” groups with a cyclopropane fragment increases the metabolic stability of the target structures and extends the scope of their therapeutic action.

Previous studies have indicated that paracrine factors (conditioned medium) increase wound closure and reduce reactive oxygen species in a traumatic brain injury in vitro model. Although the beneficial effects of conditioned medium from human adipose tissue-derived mesenchymal stem cells (hMSCA-CM) have been previously suggested for various neurological diseases, their actions on astrocytic cells are not well understood. In this study, we have explored the effect of hMSCA-CM on human astrocyte model (T98G cells) subjected to scratch assay. Our results indicated that hMSCA-CM improved cell viability, reduced nuclear fragmentation, attenuated the production of reactive oxygen species, and preserved mitochondrial membrane potential and ultrastructural parameters. In addition, hMSCA-CM upregulated neuroglobin in T98G cells and the genetic silencing of this protein prevented the protective action of hMSCA-CM on damaged cells, suggesting that neuroglobin is mediating, at least in part, the protective effect of hMSCA-CM. Overall, this evidence suggests that the use of hMSCA-CM is a promising therapeutic strategy for the protection of astrocytic cells in central nervous system (CNS) pathologies.

Poir. raw material from 2010 and 2015 were studied using modern HPLC-DAD-MS. Primarily mono- and diglycosides of O-hydroxylated (myricetin, quercetin, kaempferol) and O-methylated flavonols (isorhamnetin, laricitrin, syringetin) were identified. Long-term storage of dried raw material under standard conditions had little effect on the quantitative content of polyphenolic compounds. Acute toxicity studies of C. jubata extract showed no toxicity.

Researchers working in the area of ageing have found numerous manifestations of this process at the molecular biological level, including DNA and protein damage, accumulation of metabolic by-products, lipids peroxidation, macromolecular cross-linking, non-enzymatic glycosylation, anti-oxidant/pro-oxidant misbalance, rising of pro-inflammatory cytokines, etc. This results in an increase in the proportion of cells in growth arrest, reduction of the rate of information processing, metabolic rate decrease, and decrease in rates of other processes characterizing dynamic aspects of the organism’s interaction with its environment. Such staggering multilevel diversity in manifestation of senescence precludes (without methodology of systems biology) development of a correct understanding of its primary causes and does not allow for developing approaches capable of postponing ageing or reducing organisms’ ageing rate to attain health preservation. Moreover, it turns out that damage production and damage elimination processes, the misbalance of which results in the ageing process, can to a large extent be regulated by external signals. The purpose of this report is to provide evidence supporting this view and its compatibility with the regularities of mortality statistics, because the main idea is very simple. Even potentially a non-senescent but certainly not immortal body must start to age under inadequate conditions (like a non-melting piece of ice taken out from the deepfreeze inevitably start to melt at the temperatures above zero Celsius). This conclusion is totally consistent with existing patterns of mortality and with agelessness potential of somatic stem cells. Therefore, there is no need to build up and explore too complicated, computational and sophisticated systems models of intrinsic ageing to understand the origin of this mainly extrinsic root cause of natural ageing, which is controlled by environmental signals. In our case, a simple phenomenological black-box approach with Input–Output analysis is ample. Here Input refers to the environmentally dependent initial force of mortality, whereas Output is a rate of age-related increase of mortality force.

Radiation therapy, widely used in the treatment of a variety of malignancies in the pelvic area, is associated with inevitable damage to the surrounding healthy tissues. We have applied atomic force microscopy (AFM) to track the early damaging effects of ionizing radiation on the collagen structures in the experimental animals' bladder and rectum. The first signs of the low-dose radiation (2 Gy) effect were detected by AFM as early as 1 week postirradiation. The observed changes were consistent with initial radiation destruction of the protein matrix. The alterations in the collagen fibers' packing 1 month postirradiation were indicative of the onset of fibrotic processes. The destructive effect of higher radiation doses was probed 1 day posttreatment. The severity of the radiation damage was proportional to the dose, from relatively minor changes in the collagen packing at 8 Gy to the growing collagen matrix destruction at higher doses and complete three-dimensional collagen network restructuring towards fibrotic-type architecture at the dose of 22 Gy. The AFM study appeared superior to the optical microscopy-based studies in its sensitivity to early radiation damage of tissues, providing valuable additional information on the onset and development of the collagen matrix destruction and remodeling.

Objective: to assess parents’ attitude toward vaccines and the degree of their awareness about vaccination using a specially designed questionnaire. Materials and methods. We conducted an anonymous survey of 360 parents who stayed in a hospital to take care of their children. The questionnaire included 34 questions on parents' awareness about vaccination and their general attitude toward vaccines. Results. Our survey demonstrated that 282 children were partly or fully vaccinated, whereas 78 children were not vaccinated. A total of 79% of parents believe that vaccination is the most effective method of preventing infectious diseases. The majority of parents (80%) understand that vaccinated children are less likely to develop severe illness than those who have not been vaccinated. Almost two-thirds of parents (60%) responded that they would like to expand their knowledge on immunization and believe that measures taken to inform people about vaccines are insufficient. Results. Our findings suggest that the majority of parents have a generally positive attitude toward vaccination. However, our respondents demonstrated lack of awareness about vaccines. Therefore, educational events should be planned to raise awareness about vaccination among parents.

A number of studies have shown the relationship between the regular consumption of cruciferous vegetables and the risk of malignant tumors in certain localizations, the activation of mechanisms of alimentary adaptation of the organism under conditions of alien loads, by inducing enzymes of the biotransformation system of xenobiotics. The cruciferous vegetables are distinguished by the presence of minor components, such as indole-3-carbinol, formed during the hydrolysis of glucosinolates. The aim of the investigation was a retrospective study of the content of indoles in students' diet with subsequent quantitative analysis in different comparison groups. The study involved 250 students from a medical university aged 21 to 27 years. To assess the actual nutrition, the developed questionnaires were used, which included the most common products in the Moscow region, sources of indole glucosinolates. It was found that 44% of the respondents didn't include cruciferous vegetables in the diet, and of those who consumed sources of indoles (56% of respondents), only about half received them in the recommended amount. It should also be noted that as in men, in women the most commonly used in the diet product as a source of indoles was cabbage, it was included in the diet of 68% of the respondents who used cruciferous vegetables, rarely pekin cabbage was used (16.3%) and broccoli (16.3%). Cauliflower, radishes, Kale and horseradish was included in the diet of 7.8-14.9% of the students. Less often turnip was consumed - only by 2.1% of the students. No significant differences in the consumption of indoles in the student with deficient, normal or overweight was revealed. Also, there was no correlation between excess weight and the consumption of various indoles sources. The obtained results testify to the extremely low level of alimentary intake of indole-3-carbinol.

© 2018 Cardiovascular Therapy and Prevention. The article discusses the role of telmisartan in the treatment of arterial hypertension in patients with metabolic syndrome. Telmisartan is second-generation type 1 angiotensin II receptor blocker, which has unique pleiotropic effects due to partial affinity for receptors that activate the proliferation of subtype γ peroxisomes (PPARγ) located in adipose tissue. The interrelation of metaflamation, a specific chronic inflammatory process with pathogenetic mechanisms of development of cardiovascular diseases, including arterial hypertension, is also described in study. The role of the adiponectin peptide is considered, which synthesis is stimulated by partial PPARγ receptor agonists (as mentioned above - telmisartan). It has a positive effect on fat and carbohydrate metabolism, as well as cardioprotective properties. The conclusion contains the results of numerous randomized studies and meta-analyzes confirming the high efficacy of telmisartan in the treatment of arterial hypertension in patients with morbid obesity.

In plastic surgery we often have the need for soft tissue volume restoration of different localization, to close congenital or acquired defects as well as associated with agerelated changes in soft tissue. Autologous adipose tissue in many properties is the ideal filler for the correction of the body contour defects. However, despite its advantages, this minimally invasive technique has been secondary to more complex methods of reconstruction - flap transplantation. The main significant drawback of fat grafting is the unpredictable and ineffective survival of transplanted fat (20 to 60%, according to different authors). Currently, factors that can influence the degree of survival of adipose tissue and make it more predictable are being actively studied, in particular, the effect of Leucocyte and Platelet Rich Plasma (L-PRP). Purpose: To prove the stability of transplanted adipose tissue survival with the addition of L-PRP in breast surgery via multispiral computed tomography (MSCT) with the calculation of resorption rate of adipose tissue before transplantation in the early and in late postoperative stages. Materials and methods: In the period from 2013 to 2016, a total of 48 patients underwent surgery at the plastic surgery clinic in I.M. Sechenov First Moscow State Medical University. All patients complained of dissatisfactory appearance of the breast. Patients underwent breast lipofilling in order to correlate contour deformities. Monitoring of adipose autografts consisted of the following methods: MSCT was performed in 12 cases (5 patients after transplantation of pure adipose tissue and 7 patients after transplantation of adipose tissue enriched with L-PRP). Results: The study of the sample volumes and thickness of soft tissues after the transplantation was performed both with and without the addition of L-PRP. A steady increase in the soft tissue thickness in the breast region was revealed and an increase in volume was noted in the main group. At the same time, in patients of the control group three months after surgery a decrease in the volume and thickness of the breast soft tissues was revealed. Conclusions: The results of the study show that the improvement of breast contour after transplantation of adipose tissue both with and without the addition of L-PRP provides a steady increase in the thickness and volume of breast soft tissues. The average loss of adipose tissue after transplantation ranges from 11.62% to 17.13%. The results also confirm that MSCT is an adequate method of visualization of adipose autografts and volumetric changes in the late postoperative period.

Material and methods. One hundred patients (women 68%), aged 18—77 years, mean age 48±16, were examined before and after 8 weeks of treatment. The Morningness-Eveningness Questionnaire (MEQ) was used. Treatment response (a decrease of 50% in total MADRS scores to the 8 th week of treatment) and dynamics of depression severity (dMADRS; R) were assessed. Results and conclusion. Evening chronotype was found to be associated with poor prognosis. TCAs and SSRIs were more effective in eveningness, other antidepressants—in morningness. MEQ changes during and after treatment may reflect the resynchronizing activity of antidepressants.

The objective: To study the effectiveness and long-term outcomes of sclerotherapy for ovarian endometriomas and to substantiate the conditions and indications for minimally invasive intervention. Patients and methods: We analysed 124 interventions performed by the technique of aspiration (sclerosing) therapy of endometrioid ovarian cysts. The patients' age varied from 18 to 42 years, averaging 26.4 ± 4.2 years. The mean diameter of ovarian endomeriomas varied from 25 to 65 mm. In 84 (67.7%) of observations, pathological process was unilateral, in 72.3% - bilateral. 43 (34.6%) women had disease recurrence after previously performed cystectomy, in 28 (22.6%) endometrioid cysts were located in the only ovary and in 7 (5.6%) patients ultrasonography found that the ovary contralateral to endometrioid tumour was sharply decreased and its sections lacked the signs of antral follicles after preceding cystectomy. In fact, in 35 (28.2%) patients endometrioma was diagnosed in the only ovary. All patients after aspiration therapy of endometriomas received dienogest (2 mg) + ethinylestradiol (0.03 mg) (Siluette®, «Gedeon Richter»). Results: The recurrence rate of endometriomas during the first 12 months of follow-up was 38.7%, during the first 3 months of follow-up this parameter did not exceed 9.7%. Within 7-12 months after intervention spontaneous pregnancy occurred in 36.3% (46) of women, ending with childbirth in all cases (with the use of contraception 25 patients - 46%). Conclusion: Sclerotherapy of ovarian endometriomas with ultrasound monitoring of intervention is a minimally invasive method of treating women of reproductive age, ensuring preservation of ovarian reserve. It is not a monotherapy, its outcome is in many respects determined by the adequacy of postoperative hormonal treatment.

Perioperative antimicrobial prophylaxis (PAP) involves administration of antimicrobial agents (AMA) to patients undergoing a surgical intervention and aims to reduce the risk of postoperative infectious complications, especially at surgical sites. In the present work we assess efficiency and safety of AMA used for prevention of postoperative infectious complications. In the course of our study we pre-analyzed 576 medical histories of post-op patients aged 18 to 87 years (mean age M ± SD was 57.4 ± 14.5 years), of which 347 (60.2%) were male and 229 (39.8%) female. Only 481 histories were selected for final analysis. We assessed the choice of antibacterial therapy, the frequency of adverse reactions (AR) and infectious complications and the type of the latter. PAP regimens were consistent with the official guidelines in 207 (43.04%) cases. PAP recommendations were ignored in 274 cases (56.96%), and the timing was wrong in 364 cases (75.7%). Incorrect dosages were administered in 225 cases (46.8%). We also discovered an association between irrational PAP regimens and 1) the length of patient's stay in the intensive care unit (p = 0.003 and p < 0.005), 2) the frequency of reoperations associated with infection (p = 0.001), 3) mortality rates (p = 0.002), and 4) isolation of strains with multidrug resistance (p = 0.016). We conclude that PAP regimens for the inpatients of surgical wards are often compromised by failure to comply with the official guidelines, wrong timing and incorrect dosage, which negatively affects hospital statistics.
