Ultrastructure of hepatic cells in rabbits after injection of nanoparticles MCS-B

Belousov A.N., Laboratory Applied Nanotechnology, UA

In order to determine ultrastructural reconstructions in hepatic cells under effect of nanoparticles of magnetite (MCS-B), an experiment was conducted on 45 rabbits. Ultrastructural changes in hepatocyte organelles manifested pronounced signs of activation of reparative [...]

The influence of magnetite nanoparticles (MCS-B) on the hemolysis of erythrocytes

Belousov A.N., Laboratory of Applied Nanotechnology, UA

In Ukraine the first medical nanotechnology drugs were synthesized and patented in 1998 (http://www.nanolab.com.ua). These are such drugs as intracorporeal biocorrector (ICBB), magnet-controlled sorbent (MCS-B) and Micromage-B (Belousov A.N., 1997, 1998, 2000). Basis of the [...]

The Effect of Anticancer Nanotherapy on Lewis Lung Carcinoma

Orel V.E., Shevchenko A.D., Nikolov N.A., Dzyatkovskya N.N., Romanov A.V., Richalskiy A.Yu., Burlaka A.P., Lukin S.M., Uvarov V.N., Schepotin I.B., National Cancer Institute, UA

Introduction. Current forms of antitumor anthracycline antibiotic doxorubicin (DOXO) are highly toxic to the patient and can cause systematic complications, most notably cardiotoxicity. Systemic toxicity can seriously decrease the effectiveness of the drug since a [...]

The Method of Instant Amplification of the MCG&MEG Signals

Sklyar R., Independent researcher, UA

Simultaneous amplification of the piking up MCG&MEG neurosignals by an on-site magnetic flow has been implemented. Matrix of the sensing micro-nanocoils are distributed under the heart or brain surface with temperature of the body. Magnetic [...]

In this report the experimental data about the determination of P toxicity by optical biosensors based on the application of chemiluminescence (ChL) of Daphnia magna living media (ChL-test) and bioluminescence (BL) of Ukrainian strains of [...]

Development and practical application of biosensors based on the nanostructured silicon

Starodub N., Mel’nichenko N., Shmireva A., Shuljak L.N., National University of Life and Environmental Sciences of Ukraine, UA

In this report the principle new instrumental method of the biochemical diagnostics of the bovine leucosis, autoimmune process at the diabetes and the control mycotoxins through the registration of the formation of the specific immune [...]

A new technology for making advanced materials

Varyukhin V., Spuskanyuk V., Davydenko O., Donetsk Institute for Physics and Engineering, National Academy of Sciences of Ukraine, UA

A new combined technology including the equal channel angular hydroextrusion (ECAH), direct hydroextrusion (HE) and drawing (D) techniques for making nanostructure wire is for the first time proposed. The main purpose of our study is [...]

DFT calculations of IR and Raman spectra of Ru(bpy)2(CN)2 complex

Minaev B.F., Minaeva V.A., Minaeva V.A., Agren H., Girtu M., Bogdan Khmelnitskij national University, UA

In order to understand mechanism of electron transfer in dye-sensitized solar cell based on organic-inorganic junction we have studied the role of vibronic perturbations in metal-to-ligand and ligand-to-ligand charge transfer states excitations and in electron [...]
