Comparative study of pathomorphology of myocardial circulation under conditions of increased afterload of the left or right ventricles showed similar changes. All compartments of the coronary bed were plethoric, capillary blood stasis and perivascular edema, more pronounced in arterial vessels, were detected in both cases. These changes equally involved(More)
Adrenergic plexuses in the myocardium and adrenal medulla were studied histochemically under conditions of increased left or right ventricular afterload. Under conditions of high afterload not accompanied by heart failure the density of sympathetic myocardial innervation remained unchanged in the loaded ventricle, but increased in the intact ventricle.(More)
Histoenzymological changes, indicating inhibition of the main metabolic processes, were found in the conduction cardiomyocytes of the left ventricle and ventricular septum in experimental stenosis of the aorta. The histoenzymological changes in the conduction system of both ventricles and ventricular septum were similar in experimental stenosis of the(More)
The effect of aqueous dispersion of fullerene C60 (FC60) on the functional activity of cells involved in the phagocytosis reactions was studied. FC60 (0.01 microM/l and 0.1 microM/l) produced mainly negative effects on the activity ofnonspecific immunity cells by inhibiting the myeloperoxidase enzymatic activity, decreased the level of induced(More)
A one-dimensional dissipative magnetohydrodynamics code is used to investigate the discharge dynamics of a waveguide for high-intensity laser pulses: the gas-filled capillary discharge waveguide. Simulations are performed for the conditions of a recent experimental measurement of the electron density profile in hydrogen-filled capillaries [D. J. Spence et(More)
Compact, tunable, radially symmetric focusing of electrons is critical to laser-plasma accelerator (LPA) applications. Experiments are presented demonstrating the use of a discharge-capillary active plasma lens to focus 100-MeV-level LPA beams. The lens can provide tunable field gradients in excess of 3000 T/m, enabling cm-scale focal lengths for GeV-level(More)
During a 5-year follow-up of rescue party members exposed to radioactive effects of the Chernobyl accident no material changes were observed versus healthy donors in the content of calcium, cholesterol, atherogenic lipoproteins, dienic conjugates, insulin, thyroxin, triiodothyronine, thyroglobulin, IgA, IgG and fibrinogen. Inhibition of peroxidation and(More)
The relationship between chronotropic and inotropic components of cardiac reflexes were studied in cats using intravenous blood injections, occlusion of the abdominal aorta, pressing on eyeballs (Aschner maneuver), and occlusion of the carotid arteries. Inotropic reactions were characterized by the contractility index DPxHR/MSAP. Different reflexes were(More)
The effects of fullerene C60 (FC60) on the level of free radical and destruction processes were studied in rats with experimental adjuvant arthritis (AA). It was shown the protective effect of FC60 during AA. The effect was accompanied by an increase of the antioxidant enzymes activity, superoxide dismutase in the liver (15.96 ± 0.38 μmol/kg x s) and in the(More)
It is shown by using a two-dimensional, fully relativistic, electromagnetic particle-in-cell simulation code that a force-free magnetic configuration in collisionless, electron-positron (pair) plasmas becomes unstable against current-driven Buneman instability and subsequently there occurs a strong magnetic field energy dissipation associated with(More)
