© 2018, Pediatria Ltd.. All rights reserved. In 2011, a cohort for prospective follow-up was chose from the general population of newborns in Moscow. In 3 years of life, information on atopic dermatitis (AtD) symptoms was collected. Skin tests with allergens were performed in mothers and in children aged 1 year. Objective of the research – to correlate the sensitization of a child at the age of 1 year and sensitization of his mother with subsequent possible development of AtD in his early childhood. Study materials and methods: mother's sensitization and sensitization of a child at 1 year of age were examined separately for the possible appearance of AtD diagnostic signs at the age of 1, 2, 3 years of a child and in general in early childhood. The results of each study are presented by several methods of statistical processing: 1) analysis of conjugation tables, incl. hierarchical log-linear; 2) logistic regression models in which: a) the sensitization degree was considered, b) the sensitization was analyzed as a qualitative sign, in the presence of a papule. Results and discussion: рrospective monitoring of the cohort shows the dynamics of AtD frequency in early childhood, the number of sensitized mothers and their children. Mother's sensitization was not significant for AtD signs appearance in a child in early childhood. The sensitization of a child at the age of 1 year showed the importance of chicken egg allergen in relation to AtD signs appearance in early childhood. Study result: conclusions about the possible relationship of sensitization with AtD development in a child in early childhood.

Results of the medico-sociological research directed to studying of the ideas of the HIV-infected widespread in modern Russian society are presented in article. The obtained data have allowed to design a modern social portrait of the HIV-infected Russian. Now in representations of Russians the typical HIV-infected - the 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 that receiving which level of income we will compare with a living wage. The HIV-infected has been infected as a result of a youth error (the 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 hides the diagnosis and separates from social communications.

The one-pot process of anodic transformation of N-alkyl-3-aminopyrazoles into azopyrazoles under conditions of membraneless electrolysis in an aqueous solution of NaBr was studied for the first time. It was found that under these conditions the aminopyrazoles, which do not have a substituent at position 4, transform into the corresponding 4,4´-dibromoazopyrazoles. The corresponding yield was in the interval of 28—80%, depending on the structure of the products. The transformation of 4-substituted aminopyrazoles resulted in the formation of azopyrazoles in the yields lying within 62—86% when this process was implemented under conditions with the anodically generated Br2 acting as a mediator. A convenient method of anodic synthesis of azopyrazoles in an aqueous medium without the use of additives of chemical oxidants was proposed. The process is environmentally sound and is characterized by a high atom efficiency (>85%).

KGaA, Weinheim The rational design of broad-spectrum antivirals requires data on antiviral activity of compounds against multiple viruses, which are often not available. We have developed a panel of (+)ssRNA viruses composed of Enterovirus and Flavivirus genera members allowing to study these activity spectra. Antiviral activity profiling of a set of nucleoside analogues revealed N4-hydroxycytidine as an efficient inhibitor of replication of coxsackieviruses and other enteroviruses, but ineffective against tick-borne encephalitis virus. Furano[2, 3-d]pyrimidine nucleosides with n-pentyl or n-hexyl tails showed selective inhibition of Enterovirus A representatives. 5-(Tetradec-1-yn-1-yl)-uridine showed selective inhibition of tick-borne encephalitis virus at the micromolar level.

Copyright © 2017 John Wiley & Sons, Ltd. Stress urinary incontinence (SUI) significantly diminishes the quality of patients' lives. Currently available surgical and nonsurgical therapies remain far from ideal. At present, advances in cellular technologies have stirred growing interest in the use of autologous cell treatments aimed to regain urinary control. The objective was to conduct a review of the literature and analyse preclinical and clinical studies dedicated to various cell therapies for SUI, assessing their effectiveness, safety, and future prospects. A systematic literature search in PubMed was conducted using the following key terms: “stem,” “cell,” “stress,” “urinary,” and “incontinence.” A total of 32 preclinical studies and 15 clinical studies published between 1946 and December 2014 were included in the review. Most preclinical trials have used muscle-derived stem cells and adipose-derived stem cells. However, at present, the application of other types of cells, such as human amniotic fluid stem muscle-derived progenitor cells and bone marrow mesenchymal stromal cells, is becoming more extensive. While the evidence shows that these therapies are effective and safe, further work is required to standardize surgical techniques, as well as to identify indications for their use, doses and number of doses. Future research will have to focus on clinical applications of cell therapies; namely, it will have to determine indications for their use, doses of cells, optimal surgical techniques and methods, attractive cell sources, as well as to develop clinically relevant animal models and make inroads into understanding the mechanisms of SUI improvement by cell therapies.

© 2018 Astro Ltd. This paper describes a new approach to the fabrication of superconducting nanowire single-photon detectors from ultrathin NbN films on SiO2 substrates. The technology is based on nonlinear femtosecond optical lithography and includes direct formation of the sensitive element of the detector (the meander) through femtosecond laser exposure of the polymethyl methacrylate resist at a wavelength of 525 nm and subsequent removal of NbN using plasma-chemical etching. The nonlinear femtosecond optical lithography method allows the formation of planar structures with a spatial resolution of ∼50 nm. These structures were used to fabricate single-photon superconducting detectors with quantum efficiency no worse than 8% at a wavelength of 1310 nm and dark count rate of 10 s-1 at liquid helium temperature.

© Microscopy Society of America 2018. 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.

© 2017 American Chemical Society. Erythropoietin Fc (EPO-Fc) fusion proteins are potential drug candidates that have been designed for the treatment of anemia in humans by stimulating erythrocyte production. Such compounds can be considered performance-enhancing agents that may be used by athletes in endurance sports. This study describes the primary structure of commercially available EPO-Fc based on comprehensive liquid chromatography coupled with mass spectrometry (LC-MS) analysis. A bottom-up approach and the intact molecular weight (MW) measurement of deglycosylated protein and its IdeS proteolytic fractions was used to determine the amino acid sequence of EPO-Fc. Using multiple proteases, peptides covering unknown fusion breakpoints (spacer peptides) were identified. We demonstrated that "spacer peptides" can be used in the determination of EPO-Fc fusion proteins in biological samples using common LC-tandem MS methods.

© 2017 Informa UK Limited, trading as Taylor & Francis Group. A number of concepts exist which reveal an interaction between endogenous and psychogenic factors in stress-induced disorders in patients with schizophrenia. These concepts relate to psychological, pathophysiological, and sociological aspects of the problem. In this study we look at the respective states described within the clinical concept of reactive schizophrenia. Materials: Fifty clinical cases were included: 32 females and 18 males, mean age 38.6 ± 12.5. Thirty-three patients (66%) had a diagnosis of ‘schizophrenia’, 17 patients (34%) were diagnosed with ‘schizotypal personality disorder’ according to DSM-5 criteria. The performed examination included a clinical interview, analysis of the current clinical state, analysis of the medical history. Results: From the perspective of concept of ‘reactive schizophrenia’, the subjects of our study can be split into two groups based on their mechanism of development and psychogenic vs. endogenous contributions. These two groups may be characterized as ‘psychogenic provocation of a schizophreniform disorder’ and ‘endogenous provocation of a psychogenic disorder’ respectively. Conclusions: The results observed made it possible to re-establish the hypothesis of ‘reactive schizophrenia’. The principal feature is the specific interaction between endogenous and psychogenic factors, i.e. the psychogenic provocation of endogenous disorders.

© 2018 Hubail et al. Purpose: The aim of this study was to evaluate the progression of a case of a patient with epidermolysis bullosa (EB) since early age who survived to adulthood, presenting with recurrent skin blisters and disfiguring scars and disabling musculoskeletal deformities. Background: EB is a rare group of inherited diseases that affect the skin fragility causing it to blister in response to even minor trauma. Established novel treatments are limited in the literature due to its rarity, and more research is needed to set a global management approach. Clinical manifestations range widely from localized to generalized blistering. Methods: A rare case of EB surviving to adulthood despite the complications, which has been evaluated, treated during a relapse, and followed up. Conclusion: The described case is of considerable clinical interest due to its rarity and severity. Optimal management requires a multidisciplinary approach and revolves around the protection of the skin against slightest injury, use of careful wound care dressings, aggressive nutritional support, and early medical or surgical interventions if needed to manage any complications. Prognosis varies considerably depending on each case.

Early detection of dorsopathies is an urgent task for primary care physicians, since such conditions can combine with other chronic noncommunicable diseases (NСD) and adversely affect the course all comorbidities, consequently disimproving the quality of life of patients and increasing the frequency of their requests for medical assistance. This study aimed to determine the value of routine checkups in the context of detection of dorsopathies, NCD, and identification of risk factors (RF). We have retrospectively analyzed the patient records database of a rural outpatient clinic in the Tver region (years 2015 to 2017). The prevalence of dorsopathies and NCD RF were the subjects investigated. Fisher's exact test and Spearman's rank correlation coefficient (SRCC) were applied for the purposes of statistical processing of the results. We discovered that dorsopathy most often was a comorbidity to arterial hypertension and gastrointestinal tract diseases; it was strongly related to the NCD (SRCC = 0.506), age (SRCC = 0.383), slightly less so - to hypodynamia (SRCC = 0.146), type of the patient's occupation (intellectual or physical labor) (SRCC = 0.07). Routine checkups improve the rate of detection of dorsopathy: the more patients undergo such examinations, the more cases of dorsopathy are diagnosed. Thus, it is necessary to increase the number of working people attending the checkups in order to detect dorsopathies early and prevent them effectively.

In the clinical practice a physician quite often is at a loss due to “freedom of choice” granted by availability of direct oral anticoagulants (DOAC). If a patient with nonvalvular atrial fibrillation (AF) has indications for therapy with anticoagulants which DOAC should be preferred? What are benefits for a patient with ischemic heart disease and AF when definite NOAC is chosen and what are risks inherent of this choice? Answers to such questions are given in this paper.

Physiology of breathing during sleep predisposes to the development or worsening of the respiratory disorders in patients with chronic obstructive pulmonary disease (COPD) even if waking respiratory function remains relatively normal. Physicians, who assess patient's state only during the day, in some cases can underestimate this problem. Respiratory abnormalities can provoke insomnia, which additionally affects patient's quality of life. Supplemental oxygen and pressure support ventilation improve blood gases during sleep, but in many cases, insomnia persists. In many cases, such patients need the treatment with hypnotics. Widely used drugs in insomnia are benzodiazepines. They are rather effective but can cause respiratory depression and respiratory failure in patients with COPD. Z-hypnotics are comparable to classical benzodiazepines but much more safe and rarely worsen respiratory parameters. Melatonin and melatonin receptor agonists, antihistamines, antidepressants and neuroleptics can be effective in some patients with insomnia, but insufficient data about their safety in case of respiratory pathology restrict the use of these drugs in patients with COPD. The orexin receptor antagonist suvorexant is a novel hypnotic with the potential benefits for patients with COPD because it strongly improves sleep but does not depress respiration and has a minimal negative impact on daytime cognitive function.

The current population is characterized by a high prevalence of risk factors for the development of chronic kidney disease: hypertension, diabetes, obesity, metabolic syndrome, physical inactivity, smoking. The development of severe complications and a close connection with potentially fatal cardiovascular disorders make this disease a socially and economically significant problem. Treatment of chronic kidney disease in advanced stages belong to nephrologist duties. However, the success of preventive interventions depends on the time of their onset, which makes it relevant to identify the disease. The use of nephroprotective approaches by physicians of different specialties (general practitioners, cardiologists, gerontologists, nephrologists, endocrinologists) can significantly improve the prognosis of both those at risk of developing renal dysfunction and the existing disease. The review presents data on the clinical and laboratory efficacy of angiotensin-renin blocker use, as well as the combination of angiotensin II receptor blockers with calcium antagonists. Using the combination of the angiotensin II receptor blocker irbesartan and amlodipine as an example, we demonstrated the possibilities of nephroprotective therapy in patients with renal dysfunction.
