Specific features of magnetic structure formation in orbitally degenerate BiMnO3 manganite

The orbital structure and magnetic ordering of the Jahn-Teller multiferroic BiMnO3 manganite have been theoretically studied. It is shown that the orbital structure depends not only on the nearest-neighbor oxygen environment of manganese ions, but also on their next-to-nearest neighbors. The orbital structure significantly influences the magnetic order that forms as a result of competition between ferromagnetic and antiferromagnetic exchange interactions. © 2013 Pleiades Publishing, Ltd

Structure-Sensitive Mechanism of Nanographene Failure

The response of a nanographene sheet to external stresses is considered in terms of a mechanochemical reaction. The quantum chemical realization of the approach is based on a coordinate-of-reaction concept for the purpose of introducing a mechanochemical internal coordinate (MIC) that specifies a deformational mode. The related force of response is calculated as the energy gradient along the MIC, while the atomic configuration is optimized over all of the other coordinates under the MIC constant-pitch elongation. The approach is applied to the benzene molecule and (5, 5) nanographene. A drastic anisotropy in the microscopic behavior of both objects under elongation along a MIC has been observed when the MIC is oriented either along or normally to the C-C bonds chain. Both the anisotropy and high stiffness of the nanographene originate at the response of the benzenoid unit to stress.Comment: 19 pages, 7 figures 1 tabl

Defeat Hepatobiliary System and Pancreas in Inflammatory Bowel Disease

Extraintestinal manifestations and complications of inflammatory bowel disease currently represents one of the most mysterious phenomenon in gastroenterology. Special interest is caused damages of liver, biliary system and pancreas, as constituent organs of the digestive system and first responders not only to inflammation of the intestinal mucosa, but also for medicines taken by patients for induction and maintenance of remission

Intestinal and Extraintestinal Manifestations of Inflammatory Bowel Disease

The problem of inflammatory bowel disease draws constant attention not only of gastroenterologists but also surgeons - coloproctologists and other doctors. These related to the growing incidence of this pathology in the world, as well as the diversity of clinical manifestations, including severe extraintestinal manifestations and complications, which in clinical practice, faced not only gastroenterologists. In most cases, inflammatory bowel disease leads to permanent disability cases, which makes this problem not only medical but also socially relevant

FEATURES MICROBIOCENOSIS SHEATH IN WOMEN REPRODUCTIVE AGE WITH HYSTEROMYOMA

Purpose: To examine the state of the vaginal flora in women of late reproductive age with hysteromyoma.Materials and Methods: The study included 40 women aged 35 to 44 years diagnosed with hysteromyoma. All patients performed a microscopic and bacteriological examination of the vaginal flora.Results: In patients with hysteromyoma into the sheath showed a reduction in the number of lactobacilli, bifidobacteria and increase the detection rate and the number of nonclostridial anaerobic bacteria.Summary: hysteromyoma accompanied by changes in vaginal microflora

Objective of the study was to survey the parental awareness of the origins of infant motor asymmetry and its prevention method

Taxonomic and ecophysiological characteristics of actinobacteria in soils of the dry steppe zone of the Selenga Highlands (Western Transbaikalia)

Arid habitats have recently attracted increasing attention in terms of biodiversity research and the disco very of new bacterial species. These habitats are among the target ecosystems suitable for isolating new strains of actinobacteria that are likely to produce new metabolites. This paper presents the results on the isolation of actinobacteria from soils of the dry steppe zone of the Selenga Highlands, the characterization of their taxonomic diversity, as well as ecological and trophic properties. The bacterial counts on ISP 4 medium ranged from 6.6 × 105 to 7.1 × 106 CFU/g. The highest bacterial counts were observed in the subsurface and middle horizons of the studied soils. 28 strains of Gram-positive bacteria represented by thin-branched mycelium, coccoid and bacilliform forms were isolated. According to the results of 16S rRNA gene analysis, the isolated strains were representatives of Streptomyces, Arthrobacter, Glycomyces, Kocuria, Microbacterium, Micromonospora, Nocardioides, Pseudarthrobacter, and Rhodococcus (Actinomycetota). One isolate that showed low 16S rRNA gene sequence similarity with previously isolated and validly described species was a new species of the genus Glycomyces. It was shown that all tested strains are mesophilic, prefer neutral or slightly alkaline conditions, have growth limits in the temperature range of 5–45 °C and pH 6–9. The optimal NaCl concentration for growth of most strains was 0–1 %. The strains under study were capable of utilizing a wide range of mono- and disaccharides and polyatomic alcohols as a carbon source. The isolated strains were capable of using both organic (proteins and amino acids) and inorganic (ammonium salts and nitrates) compounds as nitrogen sources. The examinations of extracellular enzymes showed that all isolates were capable of producing catalase and amylase; 78.6 % of the total number of isolates produced protease and lipase; 53.6 %, cellulase; and 28.6 %, urease. The data obtained expand current knowledge about the diversity of microbial communities in soils of the Selenga Highlands and also confirm the potential of searching for new actinobacteria species in these soils

The history of ethical regulation of biomedical research in the CIS member states

The history of development the ethical and legislative tools for regulation the biomedical research in the states-members of Commonwealth of Independent States (CIS) in the frame of the close collaboration the Forum for Ethics Committees in the Commonwealth of Independent States (FECCIS) and Inter-Parliamentary Assembly CIS (IPA CIS) is demonstrated in this article. The collaboration between FECCIS and IPA CIS stands on the unique experience of IPA CIS in the building of the new, humanistic legislation in the field of health care and on the initiatives of FECCIS to create a single legal space inside and outside of the CIS region. The necessity to promote the dignity, rights, and well-being of human participants in health research was the real reason for creation the Model Law «On the Protection of Human Rights and Dignity in Biomedical Research in the CIS». The process of the law creation, its direction, structure, compliance with international ethical standards and implementation in the local legislation of CIS states are analysed by the main authors of Model Law «On the Protection of Human Rights and Dignity in Biomedical Research in the CIS» and presented in this review
