Stable suspensions of nanogold (NG) and nanosilver (NS) with mean particle diameter 50 and 49 nm, respectively, were prepared by laser ablation of metals in water. To assess rat's pulmonary phagocytosis response to a single intratracheal instillation of these suspensions, we used optical, transmission electron, and semi-contact atomic force microscopy. NG… (More)
In the copper metallurgy workplace air is polluted with condensation aerosols, which a significant fraction of is presented by copper oxide particles<100 nm. In the scientific literature, there is a lack of their in vivo toxicity characterization and virtually no attempts of enhancing organism's resistance to their impact. A stable suspension of copper… (More)
The efficacy and safety of different variants of left ventricular geometrical reconstruction (LVGR) in patients with dilated cardiomyopathy (DKMP) were studied in 2-stage clinical trial during 4 years. Results of left ventricle plication, "Myosplint" surgery and implantation of extracardial net framework (ECNF) complemented with mitral insufficiency… (More)
