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

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

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

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

Clinical efficacy of a betablockers therapy in patients with chronic heart failure on the background of postinfarction cardiosclerosis

Despite the fact that betablockers (BBs) are one of the main groups of therapy of patients with acute myocardial infarction (AMI), the comparative effectiveness of various BBs in patients with postinfarction cardiosclerosis (PICS) is uncertain. There was performed comparative analysis of clinical efficacy of BBs in patients with chronic heart failure (CHF) on the background of coronary heart disease (CHD), PICS. There was evaluated the impact of metoprolol succinate, carvedilol, bisoprolol and betaxolol on blood pressure (BP), left ventricular ejection fraction (LVEF), change the functional class of chronic heart failure, and mortality in patients over 4 year
