In recent years, the possibility of using magnetic nanoparticles to ensure the transfer of medicines to areas affected by malignant neoplasms has attracted much attention of researchers. Such a solution can be organized by placing the nanodose of the drug in a polymer or protein shell with the addition of ferrite nanoparticles with high values of c...

Currently, it seems more promising to combine controlled drug delivery using liposomes or other agents in combination with ferrite nanoparticles for the treatment of oncological diseases. The release of drugs can be carried out by heating the particles with an alternating magnetic field. In this case, the local temperature can be set more precisely...

We studied a biocompatibility and a bioprotector property of nanodiamond composites on reduction of the toxic action to cadmium salt. The experimental animal intragastric received with the help of a probe activated carbon and nanodiamond composite. We researched the rate of spontaneous and ascorbate-dependent lipids peroxidation and the reference l...

The analysis of welded joints of structural materials is carried out. As a result of this, in addition to the traditionally formed zone of thermal influence (HAZ), a zone of thermal deformation influence is formed in the near-seam zone, located between the welded nugget and the HAZ. The welded nugget joints in FSW is formed in the regime of structu...

Structural-dynamic models of aspirin are proposed on the basis of non-empirical quantum calculations of geometrical and electronic structure. In this work, the parameters of the adiabatic potential are determined, and the interpretation of the vibrational states of the compound under study is proposed. Structural-dynamic models of its isomers are c...

The saturation magnetization of single-crystalline garnet ferrite films of different compositions is calculated on the basis of the familiar relations of the Néel model on the sublattice structure of ferrimagnetic compounds. Other parameters of the films are calculated using the theory of strip domains and the stability theory of cylindrical magnet...

On the basis of modelling not empirical quantum calculations of geometrical and electronic structure of some isomers of substituted benzoic acids are investigated regularity in behaviour of parameters of the adiabatic potential a carboxyl fragment.

We report an effect of continuous and pulsed near infrared (808 nm) laser radiation on cells (Paramecium Caudatum) incubated with silicon (Si) nanoparticles (NPs), which were obtained by laser ablation of crystalline Si wafer in water. The data obtained indicate the possibility of enhancing the destructive effect on cells by using pulsed laser irra...

We research memory, exploratory behavior and anxiety in adult rats in an experiment. These parameters were assessed through the use of behavioral assays, namely, the Suok test and passive avoidance learning. These parameters were studied after treatment with extracts of Ginkgo Biloba and salvia. The aqueous extract of salvia and Ginkgo-Biloba contr...

The mechanism of the microcirculation's change of the face skin of the women under the influence of the sulfur silt mud application of the lake Karantinnoe of Astrakhan region was studied. The age particularities of vasorelaxation's peloid action on the microcirculation of the face skin was installed. Peloid promotes the influx of arterial blood, t...

Structural and dynamic models of dopamine and adrenaline are proposed on the basis of ab initio quantum calculations of the geometric and electronic structure. The parameters of the adiabatic potential are determined, a vibrational states interpretation of the test compound is proposed in this work. The analysis of the molecules conformational stru...
