Abstract Background The epidemiology, clinical course, and outcomes of patients with coronavirus disease 2019 (COVID-19) in the Russian population are unknown. Information on differences between laboratory-confirmed clinically diagnosed COVID-19 real-life settings is lacking. Methods We extracted data from medical records adult who were consecutively admitted for suspected infection Moscow 8 April 28 May 2020. Results Of 4261 hospitalized COVID-19, available 3480 (median age, 56 years;...
In March 2020, the World Health Organization declared that an infectious respiratory disease caused by a new severe acute syndrome coronavirus 2 [SARS-CoV-2, causing 2019 (COVID-19)] became pandemic. our study, we have analyzed large publicly available dataset, Genome Aggregation Database (gnomAD), as well cohort of 37 Russian patients with COVID-19 to assess influence different classes genetic variants in angiotensin-converting enzyme-2 (ACE2) gene on susceptibility and severity outcome.We...
The present study reports on the frequency and spectrum of genetic variants causative monogenic diabetes in Russian children with non‑type 1 mellitus. included 60 unrelated mellitus diagnosed before age 18 years. Genetic were screened using whole‑exome sequencing (WES) a panel 35 genes maturity onset young (MODY) transient or permanent neonatal diabetes. Verification WES results was performed PCR‑direct sequencing. A total 38 identified 33 out patients (55%). majority (27/33, 81.8%) had...
Abstract Background Even though the incidence of Multisystem Inflammatory Syndrome in children (MIS-C) is decreasing cases are still reported across world. Studying consequences MIS-C enhances our understanding disease’s prognosis. The objective this study was to assess short- and medium-term clinical outcomes MIS-C. Methods Prospective observational cohort at Municipal Children’s Hospital Morozovskaya, Moscow, Russia. All meeting Royal College Paediatrics Child Health (RCPCH), Centers for...
Familial hypercholesterolemia (FH) is caused by mutations in various genes, including the LDLR, APOB and PSCK9 genes; however, spectrum of these Russian individuals has not been fully investigated. In present study, mutation screening was performed on LDLR gene other FH-associated genes patients with definite or possible FH, using next-generation sequencing. total, 59 unrelated were recruited sorted into two separate groups depending their age: Adult (n=31; median age, 49; age range, 23-70)...
We report on the phenotype and reproductive history of an adult female patient with unbalanced karyotype: 8p23 18p11.3 terminal deletions 8p22 duplication. The indication for karyotyping 28-year-old was a structural rearrangement in her miscarriage specimen: 45,ХХ,der(8;18)t(8;18)(p23;p11.3). Unexpectedly, had same karyotype only one normal chromosome 8, 18, derivative chromosome, which product chromosomes 8 18 fusion loss their short arm regions. Fluorescence situ hybridization revealed...
Resource-saving processing technologies, in a broad sense, involve the production and sale of food feed products with minimal costs based on rational use all biological resources. Analyzing literary sources, it was found that only 20% valuable secondary raw materials wastes meat industry are used as for feed, medical, technical products. Bone, which is also very material wide range products, practically not our country, leads to significant losses potential opportunities implementation...
The quality of finished products is determined at the stage compaction. High-pressure cold compaction sometimes fails to provide coalescence VT-22 high-strength titanium alloy powder particles. Particle governed by mechanical characteristics, spherical particle shape and hard oxide on particles powder. This results in low strength workpieces. To ensure a compact, additives with more plastic properties are used. Simulation applied find an optimum additional its volume. process simulated use...
A modern classification distinguishes between two nosological entities posing an intermediate risk differentiated and anaplastic carcinoma: poorly thyroid carcinoma high-grade carcinoma. There are currently few studies searching for the preoperative molecular genetic markers of papillary (PTC HG), primarily because a recent WHO reclassification singling out separate entity: follicular cell-derived nonanaplastic Therefore, this work was aimed at identifying PTC HG-specific microRNAs mRNAs...
The advanced development area is an effective tool for regulating the country's economic development. However, existing preferential regime doing business does not take into account growing importance of improving standard and quality life population these territories. purpose article to substantiate need supplement indicators characterizing effectiveness areas with quality-of-life indicators. methodological tools study are based on use basic provisions methodology Institute Socio-Economic...
Powder of titanium alloy (VT-22) produced by plasma-spraying was subjected to grinding obtain powder with size less 100 microns. These powders were sprayed plasma unit using two types gases, namely, air and methane (spraying in water sputtering coating on steel support). Influence time yield required fraction studied. Morphology phase composition the grinded one under investigation. In result experiments, it appears that genuinely influences chemical compositions, but there is no effect...
Th e database of the World Health Organization (WHO) Nomenclature Committee for Factors HLA System (IPD-IMGT/HLA Database) contained information on nucleotide sequences 20272 diff erent alleles in September 2018, which 14800 were class I and 5288 found II alleles.Over last 20 years, automated Sanger technique is a prevalent approach to genome sequencing humans, animals, bacteria, viruses.However, need more rapid routine screening stimulated novel technologies multiplex DNA sequencing.Th ese...
Carrying out large-scale structural transformations of both the entire Russian economy and its individual actors is one most important tasks current stage national development. The urgency this problem has increased dramatically during COVID-19 pandemic. purpose paper to identify significant factors in pandemic that affect economic growth Russia’s regions reduce territorial inequality. use methods comparative economic-statistical analysis made it possible establish independent factor...
The effect of sintering on the mechanical properties iron-based vanadium-containing powders with various additives is studied.The results uniaxial compression testing show that specimens made powder without and compositions zinc or copper change their shape from cylindrical to barrel-type increasing pressure, whereas less dense phosphorus collapse.The graphite as an additive remains unchanged.After sintering, Brinell hardness for iron decreases, it increases those graphite, particularly...
The article shows the possibility of processing and involving in production a powder, made from wastes VT-22 alloy ingots mechanical processing. These powders are applied as protective coatings by plasma spraying method. From powder there were obtained on steel substrate Coating samples tested for adhesion with three-point bending method corrosion resistance salt mist chamber (combined coatings: metallic + paintwork material). When chamber, pitting was quickly detected combined coatings,...

 This study considers the preparation of new composite materials based on VT-22 titanium alloy powder made from waste machining ingots by plasma spraying. Two compositions were selected for study: 1 - 65% + 30% PTM-1 5% N70Y30 and 2 70% 25% PMS. The structure microstructure samples studied, X-ray phase analysis was carried out.
