The aim of the study is to increase the functional efficiency of machine learning decision support system (DSS) for the diagnosis of oncopathology on the basis of tissue morphology. The method of hierarchical information-extreme machine learning of diagnostic DSS is offered. The method is developed within the framework of the functional approach to modeling of natural intelligence cognitive processes at formation and acceptance of classification decisions.

The aim of the study was to evaluate the safe doses of commercially available nanosized colloidal silver (NCS), stabilized with polyvinilpirrolidone (PVP, food additive E1201) when administered in gastrointestinal tract of rats in the 92-day experiment in terms of the morphological changes in the internals of animals. The sample studied contained non-aggregated nanoparticles (NPs) of silver belonging to size fractions with a diameter of less than 5 nm, 10-20 nm or 50-80 nm. 80% of NPs were inside the range of hydrodynamic diameters 10.

Nanostructured amorphous silica (SiO2) is one of the priorities of nanomaterials, exposing human to the ever-increasing scale as a component of food additives, drugs and cosmetic products. According to numerous publications SiO2 nanoparticles (NPs) possess deleterious effects on animal and human cells in vitro and also exhibit inhalation toxicity. However, the biological effects in vivo of silica NPs taken orally are studied insufficiently.
