Microwave Near-Field Dynamical Tomography of Thorax at Pulmonary and Cardiovascular Activity.

The developed near-field microwave diagnostics of dynamical lung tomography provide information about variations of air and blood content depth structure in the processes of breathing and heart beating that are unattainable for other available methods. The method of dynamical pulse 1D tomography (profiling) is based on solving the corresponding nonlinear ill-posed inverse problem in the extremely complicated case of the strongly absorbing frequency-dispersive layered medium with the dual regularization method-a new Lagrange approach in the theory of ill-posed problems. This method has been realized experimentally by data of bistatic measurements with two electrically small bow-tie antennas that provide a subwavelength resolution.

Influence of the Addition of Alumina Nanofibers on the Strength of Epoxy Resins.

The paper describes the effect of the addition of alumina nanofibers on the mechanical properties of the epoxy resin. Alumina nanofibers functionalized with epoxypropyl functional groups are used in this work. The dependence of the mechanical characteristics on the amount of the additive, as well as the features of its distribution in the material, is investigated.

[Heart reHeart remodeling in patients with severe systolic dysfunction due tocancer chemotherapymodeling in patients with severe systolic dysfunction due tocancer chemotherapy.].

Objective Comparative analysis of structural and functional specific features of the heart in patients with toxic cardiomyopathy (TCMP) with a low left ventricular ejection fraction (LVEF) and severe, chronic heart failure (CHF) and in patients with idiopathic dilated cardiomyopathy (DCMP) and similar LVEF and CHF severity.Materials and Methods This observational, single-site study included 15 patients with TCMP (12 of them received treatment including anthracycline antibiotics and 3 patients received targeted therapies) and 26 patients with idiopathic DCMP. Data of echocardiography were compared for patients with TCMP and DCMP with comparably low LVEF of <40 %.

[Results of 3 years work of the Russian hospital register of chronic heart failure (RUssian hoSpital Heart Failure Registry - RUS-HFR): relationship between management and outcomes in patients with chronic heart failure].

Aim: To analyze management and outcomes in patients with CHF managed by specialists in heart failure (HF) or general cardiologists/physicians in real-life clinical practice.

Materials And Methods: Survival rate, rehospitalization rate, general health condition, and the administered therapy were evaluated for HF patients with reduced LV ejection fraction at three years of discharge from cardiological hospitals. These patients had been included in a prospective, multicenter, observational study, "The Russian Hospital HF Registry" (RUS-HFR).
