Assessing the tourist and recreational potential in the South of Russia

The article is concerned with the holistic approach to the study of the tourism potential of the South of Russia. The paper presents analyses of various techniques to the research of the tourist opportunities of territories both in Russia and in other countries. Methodological approaches are described in the study of the macroregions tourist potential. The assessment and ranking of the natural, cultural, and socio-economic potential of all administrative entities forming the South of Russia in terms of their importance for tourism have been carried out. The aggregate indicator of tourist and recreational potential of each entity has been calculated. Regions with a high level of tourist and recreational potential, relatively high, average, and relatively low are identified

Assessment of TiO2 nanoparticles accumulation in organs and their effect on cognitive abilities of mice

Because of good optical and electrical properties, TiO2 nanoparticles are widely used in many fields of industry and medicine. To assess the effect of TiO2 nanoparticles on mice cognitive abilities and their accumulation in different organs, daily, up to 2-month period, experimental mice were administrated with TiO2 nanoparticles solution. Accumulation of titanium in blood, brain, liver, kidney, lungs and feces was assessed by neutron activation analysis. Cognitive abilities in mice before and after TiO2 nanoparticles administration were evaluated in the Morris water maze behavioral test. The amount of titanium in all organs was below the limits of detection of the method and in feces it constituted 74 +/- 7 mu g/g. In the main Morris water maze behavioral test at the control points statistically significant differences were found in the parameters of treks between capable experimental and control animals.Web of Science18338437

Impact of Chronic Oral Administration of Silver Nanoparticles on Cognitive Abilities of Mice

To assess the effect of silver nanoparticles on mice cognitive abilities, daily, up to 4-month period, experimental mice were administrated with silver nanoparticles solution. Accumulation of silver in brain was assessed by neutron activation analysis. Cognitive abilities in mice before and after silver nanoparticles administration were evaluated in the Morris water maze behavioral test. No significant differences in the amounts of silver accumulated in brain were found between capable and incapable animals. Silver accumulation in brain of experimental animals in 4-months experiment was higher than in 2-months experiment for both groups. In the main Morris water maze behavioral test at the control points of 2 and 4 months no statistically significant differences were found in the parameters of treks between experimental and control animals
