Momordica Cochinchinensis (Lour.) Spreng. (Cucurbitaceae) in culture in vitro

Momordica cochinchinensis (Lour.) Spreng. (Cucurbitaceae) belongs to a group of dioecious plants, forming the seeds with a very strong woody seed coat. To study the possibility of clonic micropropagation of M. cochinchinensis plants, the experiments were carried out by the introduction of this type in culture in vitro, and selecting the most appropriate methods of reproduction

Features of the immune status of patients with acute coronary syndrome who underwent СOVID-19, depending on the number of cytotoxic T lymphocytes (CD8⁺)

The 2019 coronavirus disease (COVID-19) pandemic has had an unprecedented impact on health and economies around the world. Direct myocardial injury and cytokine storm, leading to destabilization of preexisting plaques and accelerated formation of new plaques, are two mechanisms that trigger the acute coronary syndrome in COVID-19. There is insufficient data on the immune status of patients with acute coronary syndrome who have undergone COVID-19. The aim of the study was to study T and B cell, humoral immunity depending on the number of cytotoxic T lymphocytes (CD8+) in patients with acute coronary syndrome who underwent COVID-19. Materials and methods of research: 65 men with unstable angina pectoris and acute myocardial infarction (acute coronary syndrome) from 40 to 65 years old, who had previously had COVID-19, were examined. A study of peripheral blood was carried out: complete blood count (Medonic device, Sweden), general and specific IgM, IgG, IgA, compliment fragments (Vector Best, Russia). Subpopulations of T and B lymphocytes were determined by flow cytometry. In persons with acute coronary syndrome who underwent COVID-19 with predominantly normal and elevated levels of cytotoxic T cells, a more severe course of the disease was observed: patients with acute myocardial infarction prevailed, they had longer mortality, longer treatment duration, and stent thrombosis was more common. In patients with elevated cytotoxic T cells, there was a maximum increase in erythrocytes, hemoglobin, hematocrit, lymphocytes of both the total number and subpopulations – T helpers, T-NK lymphocytes, NK lymphocytes, T lymphocytes of early and late activation, B1 and B2 lymphocytes, index of NBT-induced test. In patients with normal levels of NK cells, compared with other groups, there was an increase in spontaneous NBT activity and index, a significant decrease in C3a and C5a complement fragments. Prevalence of stent thrombosis and mortality in the group of patients with normal levels of cytotoxic T cells may indicate torpidity of the immune system in these patients with poor outcomes

THE ROLE OF EDUCATIONAL COMPLEXES IN THE IMPLEMENTATION OF THE PARTNERSHIP MODEL FORMATION OF THE NATIONAL QUALIFICATIONS FRAMEWORK

The aim of the study is to define potential of modern educational complexes in the field of formation of national system of qualifications on the basis of interpretation of procedures changes in regulation of social and labour relations. Methods. The methods involve analysis, generalisation, ordering and a technique of modelling of processes.Results. The authors describe key positions of the theory of the continuous education that provides rapprochement of requirements of employers with quality of vocational training and the content of educational process in the branch educational institutions. The possible contribution of educational complexes to creation of national system of qualifications and professional standards is considered. In this connection various forms of partnership of the given complexes with public authorities, public structures, and also employers are described.Scientific novelty. The concept of business competence characterising ability of system of vocational training is offered to satisfy the requirement of a labour market by means of active integration of educational, innovative and labour processes.Practical significance. The presented model of interaction of educational complexes and subjects of a labour market can be realised by working out of professional standards, creation of the expert centers and the innovative platforms intended to realisation of advisory activity on the basis of high schools; and also organizational-methodical support of processes of professional certification system formation. According to authors, this model will help to co-ordinate the content of professional and Federal State Educational Standards (FSES)

High accuracy calculation of 6s -> 7s parity nonconserving amplitude in Cs

We calculated the parity nonconserving (PNC) 6s -> 7s amplitude in Cs. In the Dirac-Coulomb approximation our result is in a good agreement with other calculations. Breit corrections to the PNC amplitude and to the Stark-induced amplitude $\beta$ are found to be -0.4% and -1% respectively. The weak charge of $^{133}$Cs is $Q_W=-72.5 \pm 0.7$ in agreement with the standard model.Comment: 4 pages, LaTeX2e, uses revtex4.cls, submitted to PR

High-precision calculations of dispersion coefficients, static dipole polarizabilities, and atom-wall interaction constants for alkali-metal atoms

The van der Waals coefficients for the alkali-metal atoms from Na to Fr interacting in their ground states, are calculated using relativistic ab initio methods. The accuracy of the calculations is estimated by also evaluating atomic static electric dipole polarizabilities and coefficients for the interaction of the atoms with a perfectly conducting wall. The results are in excellent agreement with the latest data from ultra-cold collisions and from studies of magnetic field induced Feshbach resonances in Na and Rb. For Cs we provide critically needed data for ultra-cold collision studies
