CHANGES IN THE CYTOKINE STATUS WITH STABLE ANGINA

This review summarizes the current evidence on the role of cytokines in the pathogenesis of ischemic myocardial damage. It described the important role of inflammation in the development of coronary heart disease. The role of individual cytokines in the pathogenesis of coronary artery disease and the most frequent forms of it - angina. It is shown that in patients with coronary heart disease progression of the disease is due to an imbalance in cytokine system, elevated pro-inflammatory cytokines (TNF, IL-1β, IL-6). Anti-inflammatory cytokines (IL-4, IL-10) inhibit the secretion of proinflammatory cytokines by limiting excessive intensity of the immune response. Revealed increasing levels of TGF-β1 as a key cytokine that promotes the development of fibrosis in the wall of the heart and blood vessels. The interrelation between improving markers of inflammation and the development of coronary heart disease, the predictive value of these markers of inflammation in patients with stable coronary heart disease: angina of effort of different functional classes

DYNAMICS OF THE LEVEL OF ANTI-INFLAMMATORY CYTOKINES IN THE TREATMENT OF STABLE ANGINA II-III FUNCTIONAL CLASSES

Purpose: to assess the dynamics of the level of anti-inflammatory cytokines (IL-4, IL-10) in the process of the standard treatment and the use of TES-therapy in patients with stable angina II-III functional class.Materials and Methods: the study investigated the level of anti-inflammatory cytokines (IL-4, IL-10) in 60 patients with angina pectoris II-III FC on the background of standard treatment and when carrying out TES-therapy.Results: in the group of patients with angina pectoris II-III functional class on the 8 days of standard therapy were observed significant changes in the content of major anti-inflammatory cytokines IL-4 and IL-10. When added to standard treatment with TES-therapy level of the main anti-inflammatory cytokines (IL-4, IL-10) for 8 days significantly decreased.Summary: the results suggest that TES-therapy allows to reduce the degree of activity of systemic inflammatory response in significantly more strokes than the standard treatment. It is therefore advisable for the inclusion of TES-therapy in the standard treatment of patients stable angina II-III functional class

Towards a microwave single-photon counter for searching axions

The major task of detecting axions or axion-like particles has two challenges. On the one hand, the ultimate sensitivity is required, down to the energy of a single microwave photon of the yoctojoule range. On the other hand, since the detected events are supposed to be rare, the dark count rate of the detector must be extremely low. We show that this trade-off can be approached due to the peculiar switching dynamics of an underdamped Josephson junction in the phase diffusion regime. The detection of a few photons\u27 energy at 10 GHz with dark count time above 10 s and the efficiency close to unity was demonstrated. Further enhancements require a detailed investigation of the junction switching dynamics

Response of a cold-electron bolometer on thz radiation from a long yba2cu3o7−δ bicrystal josephson junction

The response of the Cold-Electron Bolometers (CEBs), integrated into a 2-D array of dipole antennas, has been measured by irradiation from YBa2Cu3O7−δ (YBCO) 50 \ub5m long Josephson junction into the THz region at frequencies from 0.1 to 0.8 THz. The possibility of controlling the amplitude-frequency characteristic is demonstrated by the external magnetic field in the traveling wave regime of a long Josephson junction. The YBCO junction has been formed on the bicrystal Zr1−xYxO2 (YSZ) substrate by magnetron sputtering and etching of the film. CEBs have been fabricated using an Al multilayer structure by a self-aligned shadow evaporation technique on Si substrate. Both receiver and oscillator have been located inside the same cryostat at 0.3 K and 2.7 K plates, respectively

Electrocardiographic signs of impaired depolarization (fragmented QRS, early ventricular repolarization, etc.) as markers of left ventricular systolic dysfunction

Aim. To study the relationship between a decrease in left ventricular (LV) ejection fraction (EF) and conventional electrocardiographic (ECG) signs associated with myocardial structure changes (pathological Q wave, ventricular arrhythmias), and relatively novel and less studied (fragmented QRS (fQRS), early ventricular repolarization (EVR)) and to evaluate their significance for identifying patients with mildly-reduced EF (mrEF).Material and methods. The study included 148 patients who were treated and examined at the Almazov National Medical Research Center. During the ECG analysis, fQRS, EVR, pathological Q wave, and ventricular arrhythmias (VAs) were assessed. Echocardiography data were analyzed. Statistical processing was carried out, including Fisher and chi-squared test, as well as correlation and ROC analysis.Results. Depending on the EF level, patients were divided into three groups: group 1 — patients with reduced EF (rEF) (<40%); group 2 — patients with mrEF (40-49%); group 3 — patients with preserved EF (pEF) (>50%). In the 1st group (with rEF), fQRS was registered in 16 (51,6%) patients, in the 2nd (with mrEF) — in 13 (44,8%), in the 3rd (with EF >50%) — in 16 (18,2%). Pathological Q wave was detected in the 1st group (rEF) in 20 (65%) patients, in the 2nd (mrEF) — in 10 (35%); in the 3rd (pEF) — in 15 (18%) (p<0,001). ROC analysis found that fQRS is more important for identifying patients with mrEF. In the 1st group (rEF), EVR was registered in 2 (6,5%) patients, in the 2nd (pEF) — in 2 (6,9%), in the 3rd (EF>50%) — in 11 (12,5%); the differences were not significant (p=0,5). The relationship of EVR, the number of PVCs and the presence of ventricular tachycardia with EF was not revealed.Conclusion. FQRS is significantly more often observed with a decrease in EF and may be a marker of an mildly-reduced EF. There were no significant correlations between EVR and EF. There was also no relationship between VAs and LV systolic dysfunction
