Assessment of antibiotic resistance genes in soils polluted by chemical and technogenic ways with poly-aromatic hydrocarbons and heavy metals.

Anthropogenic activities are leaving lots of chemical footprints on the soil. It alters the physiochemical characteristics of the soil thereby modifying the natural soil microbiome. The prevalence of antimicrobial-resistance microbes in polluted soil has gained attention due to its obvious public health risks.

[Involvement of the trigeminal nerve system in the sense of smell].

A systematic review of literature on the issue of involvement in the sense of smell, as well as the interaction between the trigeminal and olfactory nerves, was carried out. The article discusses the features of the chemical perception systems, as well as the treatment of olfactory disorders using transcranial electrical stimulation of the trigeminal nerve.

IMPACT OF NON-CONTACT ELECTROMAGNETIC RADIATION ON LIVING ORGANS AND TISSUES.

This study aims to create a laboratory unit for induction heating and assess how possible it is to use local induction heating in solving problems related to biotechnology and medicine. This article contains a description of a method for non-contact local hyperthermal heating of biological tissues using inductive electromagnetic radiation. The method is based on the introduction of a composite material consisting of a polymer base and incorporated ferromagnetic particles into living tissues.

Quorum-Sensing Inhibition by Gram-Positive Bacteria.

The modern paradigm assumes that interspecies communication of microorganisms occurs through precise regulatory mechanisms. In particular, antagonism between bacteria or bacteria and fungi can be achieved by direct destruction of the targeted cells through the regulated production of antimicrobial metabolites or by controlling their adaptive mechanisms, such as the formation of biofilms. The quorum-quenching phenomenon provides such a countermeasure strategy.

[Use of local induced hyperthermia in the treatment of malignant tumors].

The way of a local contactless hyperthermal induction heating for biological tissues is developed on the basis of implantation of substituting composite applicator made of a polymeric material with incorporated ferromagnetic particles. The simplified mathematical model of the physical processes proceeding at a sample heating is presented. Model results are used for approximation of the experimental data.
