Biological and economic characteristics of the allotetraploid with genomic formula DDAuAu from the cereal family

The synthesis  of new  allopolyploid  cereal  genotypes is an important task aimed  at involving new  genetic resources in breeding programs. Diploid species of the genera Triticum and Aegilops – bread  wheat  relatives – are an important source of agronomically  valuable traits. A tetraploid synthetic  with genomic formula DDAuAu was obtained by N.A. Navruzbekov through crossing Aegilops tauschii Coss. and Triticum urartu Thum. ex Gandil. The purpose of this work was to study  the  chromosomal composition and  biological  and  commercially  important traits of the  tetraploid. Cytogenetic analysis using fluorescent in situ hybridization  showed the  presence of all chromosomes of the D genome in the chromosomal complement of the synthetic. By means  of stepwise  vernalization, the winter habit was established for the tetraploid synthetic with the optimum vernalization requirement of 45 days. Under greenhouse conditions, two groups of genotypes were found whose flowering dates differed by 6.5 days, which may indicate an allelism at the Vrn-3 locus. The coloring of various organs of the tetraploid plant, such as coleoptile,  stem, anthers,  and glumes  of the spike, was revealed. The coloration  of the aleurone layer of the grain may indicate that the donor species T. urartu is a carrier of the Ba gene that controls its blue color. A new morphotype of leaf pubescence was found. In terms of productivity, the tetraploid is comparable to bread wheat. Grains are characterized by a supersoft structure and high wet gluten  content, from 39–45 to 65 %, in the field and greenhouse conditions, respectively. Thus, the tetraploid can be used to create  new wheat  genotypes as a source  of untapped genetic diversity, as well as a new genetic model  for studying  the patterns of evolution  of polyploid plants

Management of chronic obstructive pulmonary disease

This study aimed to determine the level of senior medical students’ knowledge in the management of patients with COPD, based on the method of anonymous questioning. This research work describes the results of the second stage of the ASCO project (Assessment of Senior Medical Students in the Field of COPD) conducted in 2017-2019 among 338 senior medical students from six large cities of Russia and Ukrain

Large-scale association analysis identifies new lung cancer susceptibility loci and heterogeneity in genetic susceptibility across histological subtypes.

Although several lung cancer susceptibility loci have been identified, much of the heritability for lung cancer remains unexplained. Here 14,803 cases and 12,262 controls of European descent were genotyped on the OncoArray and combined with existing data for an aggregated genome-wide association study (GWAS) analysis of lung cancer in 29,266 cases and 56,450 controls. We identified 18 susceptibility loci achieving genome-wide significance, including 10 new loci. The new loci highlight the striking heterogeneity in genetic susceptibility across the histological subtypes of lung cancer, with four loci associated with lung cancer overall and six loci associated with lung adenocarcinoma. Gene expression quantitative trait locus (eQTL) analysis in 1,425 normal lung tissue samples highlights RNASET2, SECISBP2L and NRG1 as candidate genes. Other loci include genes such as a cholinergic nicotinic receptor, CHRNA2, and the telomere-related genes OFBC1 and RTEL1. Further exploration of the target genes will continue to provide new insights into the etiology of lung cancer

Shared heritability and functional enrichment across six solid cancers

Correction: Nature Communications 10 (2019): art. 4386 DOI: 10.1038/s41467-019-12095-8Quantifying the genetic correlation between cancers can provide important insights into the mechanisms driving cancer etiology. Using genome-wide association study summary statistics across six cancer types based on a total of 296,215 cases and 301,319 controls of European ancestry, here we estimate the pair-wise genetic correlations between breast, colorectal, head/neck, lung, ovary and prostate cancer, and between cancers and 38 other diseases. We observed statistically significant genetic correlations between lung and head/neck cancer (r(g) = 0.57, p = 4.6 x 10(-8)), breast and ovarian cancer (r(g) = 0.24, p = 7 x 10(-5)), breast and lung cancer (r(g) = 0.18, p = 1.5 x 10(-6)) and breast and colorectal cancer (r(g) = 0.15, p = 1.1 x 10(-4)). We also found that multiple cancers are genetically correlated with non-cancer traits including smoking, psychiatric diseases and metabolic characteristics. Functional enrichment analysis revealed a significant excess contribution of conserved and regulatory regions to cancer heritability. Our comprehensive analysis of cross-cancer heritability suggests that solid tumors arising across tissues share in part a common germline genetic basis.Peer reviewe

Among them gram-negative bacteria composed 42,1 %, gram-positive – 38,8 % and 19,1 % from all agents there were yeasts of the genus Candida. More frequent than others were separated the enterococcuses: 171 strains of Enterococcus faecalis, 150 of strains E. faecium and 148 cultures Klebsiella pneumoniae

The Assessment of Physicians' and Senior Medical Students' Knowledge in the Field of Community-acquired Pneumonia: Preliminary Results of the KNOCAP-II Project (2017-2019).

Community-acquired pneumonia (CAP) is one of the most relevant problems of modern medicine. Today, CAP takes 4th place in the structure of mortality (after cardio­vascular, cerebrovascular diseases and Malignant neoplasms) and 1st place among all deaths from infectious diseases. The aim of the study is to assess the level of general physician' and senior medical students' basic knowledge in CAP treatment. The article represents the results of anonymous prospective surveys within the framework of the second stage of KNOCAP multi-centered research project (full name of the project «The assessment of physician' and students' knowledge of community-acquired pneumonia basics») aimed at accessing the knowledge and preferences of doctors and students on the fundamental issues in diagnosis and treatment of community-acquired pneumonia. The survey conducted in 2017-2019 involved 588 physicians and 394 students from seventeen Russian, Kyrgyzstan and Ukrainian centers. The method of anonymous questioning was used in this study, for which an original questionnaire was developed on the basis of current clinical recommendations. The following fundamental questions caused the greatest difficulties in the respondents: terms for a repeated X-ray examination in positive dynamics of CAP treatment, the choice of main diagnostic criteria of CAP, the choice of the typical mistakes of CAP treatment, the choice of the initial antimicrobial therapy. In general, the respondents' knowledge in CAP patients' management deviates significantly from the current clinical guidelines, as of 2010, and from the new clinical guidelines draft, 2018-2019. Currently, there is a need to increase the level of knowledge and improve the professional activities of therapists and senior medical students, as a multicenter section of the knowledge and preferences of specialists in many issues revealed their insufficient level for the correct management of patients with CAP
