The assortment of plants for a shadow garden in Bashkortostan, and also regions of South Urals is insignificant, it is not enough data on features of biology of shade and shade-enduring plants. Among them there are species and sorts of Brunnera Stev. genus. Brunnera are decorative and deciduous and beautiful-blossoming plants with the long period of blossoming. Studying of some biological features (seasonal rhythm of growth and development, morphometric param- eters, introduced stability) of five sorts of B.

The present research is devoted to the problems of a complex estimation of functional reserves of the respiratory system of young untrained persons staying in the different conditions of life. The lung function of healthy young female persons at rest and after dosed physical activity, which used the sample of Martin, was investigated by standard and forced methods of spirometry.

The paper shows the opportunities of using WBC formula to evaluate the adaptation status of urban and rural residents to the complex of socio-economic and environmental conditions of the region. It was found that the age of the second physiological chiasm of Oryol region’s children accounts for a period of 5–6 years, which cor- responds to the generally accepted standards. Physiological highly adaptive responses were recorded among 47.4% of adolescents, 67% of rural and 36.7% of urban residents.

In the last decade, a large number of factual data about the steadily increasing complications caused by gram-positive and gram-negative microorganisms, as well as caused by fungi of the genus Candida, have been obtained. The developed situation was a powerful stimulus for the search and creation of new products containing substances with pronounced chemical-physical properties and high biological activity. The modern and promising direction was the using of nano- technology, in particular, metallic nanoparticles.

The aim of the research is to determine the phylogenetic connections of scorpion representatives of the genus Mesobuthus living in the Lower Volga region and their comparison with other taxa (subspecies and species of this genus). For this, scorpions were collected on the territory of the Lower Volga region. The nucleotide sequences of the collected specimens were deciphered and compared with the sequences of species of the genus Mesobuthus from other regions of the Palearctic. The phylogenetic connections of the investigated objects are determined.

Investigations of disorders of the heart’s structure and functions at the early stages of development, elaboration of prophylactic measures preventing or decreasing the risk of myocardium in- farction with the presence of the hypertension disease continue to remain unconditionally topical up to now. The aim of this ex- perimental work lies in finding out the morphofunctional signs of cardiovascular lesions produced by stress factors with the presence of arterial hypertension.

Gold nanoparticles are intensively studied in biomedicine. Evaluation of their biocompatibility is highly important. In aquatic systems, microalgae, being the primary producers, are the base of the trophic webs. They are the first target for most of the pollutants present in the medium. To study the toxicity of ionic and colloidal gold on the saltwater microalga Dunaliella salina. To describe several physicochemical characteristics of nanomaterials that affect their toxicological efficiency.

In the Saratov region all species of Iris are listed in the regional Red Book, with this connection, to preserve these plants, it is necessary to introduce them in an extensive researches, protection and establishing them in the literature. special interest is the study of seeds due to the direct relation with the potential possibility of generative propagation of Iris species, the article presents the results of an anatomical study of the seeds of seven species which belong to Iris L. in Saratov region flora.

Azospirillum bacteria are engaged in associative interactions with a wide range of plants. In this type of interaction, there formed no specialized structures like nodules, which are characteristic of the legume-Rhizobium symbiosis. The formation of biofilms by Azospirillum on the plant root surface can be important for the successful functioning of plant-microbe associations. Scarce data exist on the role of cell surface protein structures in the formation and stabilization of Azospirillum biofilms. It is known that as compared to A.
