    Partitioning Edge-Colored Hypergraphs into Few Monochromatic Tight Cycles

    Confirming a conjecture of Gy´arf´as, we prove that, for all natural numbers k and r, the vertices of every r-edge-colored complete k-uniform hypergraph can be partitioned into a bounded number (independent of the size of the hypergraph) of monochromatic tight cycles. We further prove that, for all natural numbers p and r, the vertices of every r-edge-colored complete graph can be partitioned into a bounded number of pth powers of cycles, settling a problem of Elekes, Soukup, Soukup, and Szentmikl´ossy [Discrete Math., 340 (2017), pp. 2053–2069]. In fact we prove a common generalization of both theorems which further extends these results to all host hypergraphs of bounded independence number

    Previously, we identified a metabotropic glutamate receptor 4 (mGluR4) as a potential target for drugs and predicted that activation of mGluR4 could provide a palliative advantage in the treatment of Parkinson's disease. Determine the mechanism of action of Rapitalam in vitro on a cell culture with mGluR4 over expression. The HEK293T cell line expressing human mGluR4 was used in the wor

    Dyssynchrony of the heart as a pathogenetic mechanism of the chronic cardiac insufficiency progression on the backgroound of ischemic heart disease or physiological aging of the heart

    This publication covers the mechanisms of fibrous remodeling of the aging heart, formation of the fibrosis and dyssynchrony. There are presented the information about the details of the types of dyssynchrony, diagnosis, course and influence on the progression of CHF. The publication also presents the changes of myocardial synchrony after the improvement of myocardial blood supply as a result of revascularizatio

    Effect of antagonist mineralocorticoid receptors Eplerenon on the dynamics of QT interval dispersion in patients with acute elderly aged

    Get PDF
    Currently, there is an increase in the frequency of cardiovascular diseases, including acute coronary syndrome (ACS), while in the Russian Federation due to ACS there is a high mortality rate from sudden cardiac death (SCD). The aim of the work is a comparative analysis of the effect of mineralocorticoid receptor antagonists (MRA) of eplerenone on the predictors of SCD development in patients with ST elevation myocardial infarction (STEMI) with a moderately abnormal ejection fraction(EF) of the left ventricle (LV) in the early stages of the diseas

    Effect of magnetic and non-magnetic impurities on highly anisotropic superconductivity

    We generalize Abrikosov-Gor'kov solution of the problem of weakly coupled superconductor with impurities on the case of a multiband superconductor with arbitrary interband order parameter anisotropy, including interband sign reversal of the order parameter. The solution is given in terms of the effective (renormalized) coupling matrix and describes not only TcT_c suppression but also renormalization of the superconducting gap basically at all temperatures. In many limiting cases we find analytical solutions for the critical temperature suppression. We illustrate our results by numerical calculations for two-band model systems.Comment: 18 pages (12pt) RevTeX, 4 postscript figure
