Influence of beta-blockers on mechanical dyssynchrony and cardiac remodeling in patients with ischemic chronic heart failure in the setting of revascularization
Diastolic dysfunction (DD) and cardiac dyssynchrony (DS) are involved in the progression of chronic heart failure (CHF). A comparative analysis was conducted of the effect of a 6-month course of nebivolol and bisoprolol on DD, DS and metalloproteinase-9 (MMP-9) level in patients with ischemic chronic heart failure with preserved ejection fraction (HFpEF) and with midrange ejection fraction (HFmrEF), as well as in patients with comorbid type 2 diabetes mellitus (T2DM) in the setting of coronary artery bypass grafting (CABG) after 6 months of therap
CaCu2(SeO3)2Cl2: spin-1/2 Heisenberg chain compound with complex frustrated interchain couplings
We report the crystal structure, magnetization measurements, and
band-structure calculations for the spin-1/2 quantum magnet CaCu2(SeO3)2Cl2.
The magnetic behavior of this compound is well reproduced by a uniform spin-1/2
chain model with the nearest-neighbor exchange of about 133 K. Due to the
peculiar crystal structure, spin chains run in the direction almost
perpendicular to the structural chains. We find an exotic regime of frustrated
interchain couplings owing to two inequivalent exchanges of 10 K each. Peculiar
superexchange paths grant an opportunity to investigate bond-randomness effects
under partial Cl-Br substitution.Comment: Extended version: 9 pages, 7 figures, 4 table

Development and validation of methods of quantitative determination of the new antidiabetic drug in the blood plasma of rats by high performance liquid chromatography with mass spectrometric detection
We developed a method of quantification of the new antidiabetic drug 3-(1h-benzimidazole-2-yl)-1,2,2-trimethyl-cyclopentane-carbonic acid (c7070) in the blood plasma of rats by high-performance liquid chromatography with mass-spectrometric detectio
Terrestrial heat flow and its role in petroleum geology
This paper describes an overview of mineral resources exploration survey by geothermal method based on the studies of terrestrial heat flow, anomalies varying in strike, in depth, physical behavior and in time. Applying geothermometry in oil-gas deposit exploration, based on paleotemperature modeling of sedimentation sequences was illustrated
Application of phosphocreatine in the treatment of a patient with acute myocardial infarction on the background of auxiliary circulation
The clinical case of maintaining the patient with a sharp transmural myocardial infarction front septal areas and tops of the left ventricle, the cardiogenic shock of the II degree and alveolar hypostasis of lungs are described. In the treatment of the patient auxiliary blood circulation in the form of installation of an intra aortal balloon counterpulsation in the descending department of an aorta was applie
Results of investigation of muon fluxes of superhigh energy cosmic rays with X-ray emulsion chambers
The overall data from the investigation of the cosmic ray muon flux in the range of zenith angles (0-90) deg within the energy range (3.5 to 5.0) TeV is presented. The exposure of large X-ray emulsion chambers underground was 1200 tons. year. The data were processe using the method which was applied in the experiment Pamir and differred from the earlier applied one. The obtained value of a slope power index of the differential energy spectrum of the global muon flux is =3.7 that corresponds to the slope of the pion generation differential spectrum, gamma sub PI = 2.75 + or - .04. The analysis of the muon zenith-angular distribution showed that the contribution of rapid generation muons in the total muon flux agree the best with the value .2% and less with .7% at a 90% reliability level
