HISTORICAL GENESIS OF PEDAGOGICAL EDUCATION IN RUSSIA IN THE 19TH – EARLY 20TH CENTURIES

Background. Pedagogical education in our country has been in the ever reforming process. Being subject to current realities, the nature, goals, and state and public expectations from pedagogical education are to be reviewed. There was a similar process at the break of pedagogical education in Russia. In this regard, historical genesis of pedagogical education in Russia in the 19th – early 20th centuries provides an opportunity to analyze some challenging issues facing the country over the considered period, to specify the patterns for the formation and development of pedagogical education, and to designate the peculiarities thereof. Purpose. The article aims to analyze the formation and development of pedagogical education in Russia in the 19th – early 20th centuries. Materials and methods. A retrospective analysis is the key research method. In addition, historical-structural, and comparative and contrastive methods were used to conduct a systemic analysis of the development of pedagogical education in Russia in the 19th – early 20th centuries. The article is based on the evidence from archival records, research material data, regulatory legal acts, and popular science fiction of the reviewed period. Results. The first extensive actions in the development of pedagogical education in Russia were taken in the 18th century. Since that time and throughout the 19th century, there was a gradual advance in pedagogical education. In addition to the main subjects, there were some disciplines specific to the pedagogical content knowledge (didactics, pedagogy, teaching methods, psychology, etc.) in the curriculum cycle for future teachers. First-ever domestic methodological guidelines for individual subjects emerged in the country. In Russia, there predominately existed male pedagogical education. According to the archival research and literature review, the country experienced an acute teacher shortage during the 19th century. To eliminate it, pedagogical departments were established at district Imperial Universities in Russia in 1804; in 1816, the Main Pedagogical Institute was founded to form the basis for other pedagogical institutions; in 1860, two-year pedagogical courses appeared at the Imperial Universities; in 1876, the issue regarding female pedagogical education was brought up, which led to the creation of the first pedagogical institute for women in 1903. In order to enhance the prestige of the teaching profession in Russia in the 19th – early 20th centuries, the state equated it to the public service, wherein each teaching position corresponded to a certain rank with all the privileges and state support; compensated for the costs of housing, lighting, heating, and educational literature; supported teachers’ families and encouraged childbirth among teachers and lecturers; provided pensions and gave the opportunity to receive awards that granted additional financial support. Having analyzed the problems of developing pedagogical education in the 19th – early 20th centuries, there are similar problems observed in modern Russia. Therefore, nowadays, it is vital to consider the methods and state initiatives for supporting and raising the prestige of the teaching profession of that time. In this regard, the relevance of the presented research is beyond doubt

Bouquet Formation Failure in Meiosis of F1 Wheat–Rye Hybrids with Mitotic-Like Division

Bouquet formation is believed to be involved in initiating homologous chromosome pairings in meiosis. A bouquet is also formed in the absence of chromosome pairing, such as in F1 wheat–rye hybrids. In some hybrids, meiosis is characterized by a single, mitotic-like division that leads to the formation of unreduced gametes. In this study, FISH with the telomere and centromere-specific probe, and immunoFISH with ASY1, CENH3 and rye subtelomere repeat pSc200 were employed to perform a comparative analysis of early meiotic prophase nuclei in four combinations of wheat–rye hybrids. One of these, with disomic rye chromosome 2R, is known to undergo normal meiosis, and here, 78.9% of the meiocytes formed a normal-appearing telomere bouquet and rye subtelomeres clustered in 83.2% of the meiocytes. In three combinations with disomic rye chromosomes 1R, 5R and 6R, known to undergo a single division of meiosis, telomeres clustered in 11.4%, 44.8% and 27.6% of the meiocytes, respectively. In hybrids with chromosome 1R, rye subtelomeres clustered in 12.19% of the meiocytes. In the remaining meiocytes, telomeres and subtelomeres were scattered along the nucleus circumference, forming large and small groups. We conclude that in wheat–rye hybrids with mitotic-like meiosis, chromosome behavior is altered already in the early prophase

A Rare Case of Charcot-Mari-Tooth Disease Type 2S in a 20-year-old Man

Charcot-Marie-Tooth disease type 2 (CMT2S) is rare form of Charcot-Marie-Tooth disease (CMT) that is characterized by a mutation in the IGHMBP2 gene. This gene encodes a helicase superfamily member that binds a specific DNA sequence from the region of the immunoglobulin mu chain switch. Mutation of this gene leads to spinal muscle atrophy with respiratory distress type 1 and CMT2S. This case report presents a 20-year-old male with genetically confirmed CMT2S having clinical respiratory involvement and symmetrically involved lower extremities. DNA sequencing revealed a previously unknown heterozygous mutation in the exone 2 of the IGHMBP2 gene leading to the replacement of the amino acid in the 46 position of the protein (chr11q13.3: 68673587 G>C). These atypical features widen the clinical spectrum of CMT2S. In describing this clinical case, we also improve diagnostic management and try to increase the alertness of various doctors towards neuromuscular diseases, including CMT

Immunogenetic characteristics of potential donors of hemapoietic stem cells recruited in the North Caucasus

Aim of the study was to investigate the immunogenetic characteristics of the potential donors of hematopoietic stem cells recruited in the North Caucasus and the distribution features of HLA alleles and multilocus haplotypes. Material and methods. Next Generation Sequencing technology was used to identify HLA-A, -B, -C, -DRB1 and -DQB1 alleles from 2663 unrelated bone marrow volunteers living in the Chechen Republic, Stavropol region, Republic of Dagestan. Mass parallel sequencing was performed using the MiSeq™ System («Illumina Inc.», USA). HLA allele and haplotype frequencies were estimated via maximum-likelihood analysis from genotypic data through an expectation-maximization (EM) algorithm for unknown gametic phase using Arlequin v. 3.5.2.2. Results and discussion. In studied population, 47 HLA-A, 77 HLA-B, 39 HLA-C, 54 HLA-DRB1, 22 HLA-DQB1 alleles were selected. Thirteenth alleles, HLA-A*02:01, HLA-A*01:01, HLA-B*13:02, HLA-B*51:01, HLA-C*06:02, HLA-C*04:01, HLA-C*07:02, HLA-DRB1*07:01, HLA-DRB1*13:01, HLA-DQB1*03:01, HLA-DQB1*02:02, HLA-DQB1*06:03, DQB1*03:02 exhibit frequencies over 10 %. The highest frequency extended haplotype HLA-A*02:01-B*13:02-C*06:02-DRB1*07:01-DQB1*02:02, was observed frequencies of 4,5 %. Routine HLA typing allowed us to define 13 new HLA alleles

Research on selected wildlife infections in the circumpolar arctic:a bibliometric review

Abstract One Health, a multidisciplinary approach to public health, which integrates human, animal, and environmental studies, is prudent for circumpolar Arctic health research. The objective of our bibliometric review was to identify and compare research in select infectious diseases in Arctic wildlife species with importance to human health indexed in English language databases (PubMed, Scopus) and the Russian database eLibrary.ru. Included articles (in English and Russian languages) needed to meet the following criteria: (1) data comes from the Arctic, (2) articles report original research or surveillance reports, (3) articles were published between 1990 and 2018, and (4) research relates to naturally occurring infections. Of the included articles (total n = 352), most were from Russia (n = 131, 37%), Norway (n = 58, 16%), Canada (n = 39, 11%), and Alaska (n = 39, 11%). Frequently reported infectious agents among selected mammals were Trichinella spp. (n = 39), Brucella spp. (n = 25), rabies virus (n = 11), Echinococcus spp. (n = 10), and Francisella tularensis (n = 9). There were 25 articles on anthrax in eLibrary.ru, while there were none in the other two databases. We identified future directions where opportunities for further research, collaboration, systematic reviews, or monitoring programs are possible and needed

Mosaicism in preimplantation human embryos

Since the very first publications on preimplantation genetic testing, researchers have faced a serious problem — a high mosaicism level in the preimplantation human embryos obtained by means of in vitro fertilization cycles. The nature of this mosaicism and its high impact on embryo development draws attention to this issue. In this research we studied the cells from different parts of preimplantation human embryos with mosaicism in the trophectoderm cells detected using Next-generation Sequencing (NGS). Six human blastocysts with mosaicism in their trophectoderm cells were each sectioned in three parts: two containing only trophectoderm cells and one predominantly inner cell mass. These parts were then analyzed individually. Our data indicate that the proportion of aneuploid cells in bioptate taken for preimplantation genetic testing does not necessarily reflect the true chromosomal status of the whole embryo and cannot be extrapolated to that in the embryoblast cells. The results of our study strongly suggest that mosaicism revealed in blastocyst reduces the likelihood of finding the euploid chromosome set in the other parts of the embryo. Karyotypes of cells from different parts of mosaic embryos show low concordance. Chromosomal abnormalities in mosaic embryos are unpredictably diverse, which may lead not only to loss of conception, but also to the development of genetic disease in the offspring. According to our data, the mosaic rate tends to increase in the samples containing trophectoderm adjacent to the embryoblast, which may have physiological significance for the implantation. Comparative studies focused on the concordance of mosaicism level of and the type of chromosomal abnormalities detected in different parts of preimplantation human embryos will improve clinical recommendations regarding the transfer of mosaic embryos

Diversity and Distribution of Helminths in Wild Ruminants of the Russian Arctic: Reindeer (<i>Rangifer tarandus</i>), Muskoxen (<i>Ovibos moschatus</i>), and Snow Sheep (<i>Ovis nivicola</i>)

The Russian Arctic supports wild sympatric ruminants and their data-deficient helminths. In this study, we: (1) collected fecal samples of wild and semiwild reindeer (Rangifer tarandus), muskoxen (Ovibos moschatus), and snow sheep (Ovis nivicola) across Palearctic North territories: Arkhangelsk Oblast (including Novaya Zemlya archipelago), Karelia and Sakha Republics, Kola, Yamal, Taimyr, and Chukotka Peninsulas, Bering, Svalbard, and Wrangel Islands; (2) conducted a coprological survey (noninvasive life-time method preferable for protected animals) to obtain eggs and larvae of helminths inhabiting digestive, respiratory, nervous, and muscular systems; (3) identified helminths according to their morphology and DNA sequences; (4) estimated parasite load per host; (5) analyzed our findings. Varestrongylus eleguneniensis (in reindeer) was reported for the Palearctic for the first time, while Orthostrongylus sp. was reported both for R. tarandus and for the Palearctic for the first time. Capillarid-type eggs were reported for snow sheep for the first time. The question of the role of wild Arctic ruminants as vectors for rotifers was raised
