Expiratory Lung Volumes of Young People at Rest and Recovery Period after a Dosed Physical Load

Authors: Sevryukova G. A., Isupov I. B., Shmarina Y. G., Ryaskova K. A., Belova B. A.

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.

Brunnera – Rare Decorative Culture for Shadow Garden

Authors: Zhigunov O. Y., Karimova O. A., Anishchenko I. Y.

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.

About the Biology of the Invasive Species Hordeum jubatum L. in Bashkir Trans-Urals

Authors: Abramova L. M., Baymurzina Z. M., Yanturin S. I.

The results of researches of 7 coenopopulations of North American invasivespeciesHordeumjubatumL.(Poaceae)inthe Trans-Urals of the Republic of Bashkortostan. Hordeum jubatum spreads on the steppe zone of the region. It dominates over other plants and it is share of participation in the community is 45,5–60,5%. The density of grass invasive species – 9–18 plants per 1 m2.Each plant produces 35 to 68 shoots, on average, is more than 600 shoots per 1 m2. The biomass of the type is no more than 0.25 kg/m2. Seed production is 39–54 pcs.

The Influence of Aqueous Dispersions of Metal Nanoparticles on the Adhesive Properties of the Standard and Clinical Strains of Staphylococcus aureus

Authors: Nechayeva O. V., Bespalova N. V., Glinskaya E. V., Shurshalova N. F., Shulgina T. A., Nechayeva O. V., Torgashova A. S.

The initial stage of interaction of infectious agents with micro-organisms cells is the process of adhesion. So there is a need to develop methods that reduce the adhesive activity of microorganisms. Aim: to study the impact of water and water dialyzed dispersion of silver and copper nanoparticles obtained by biochemical synthesis, on the adhesive properties of the standard and clinical strains of S. aureus. Using standard techniques for cells of S.

The Influence of Growth Conditions of Bacteria Azospirillum lipoferum Sp59b on the Biological Activity of Their Glycopolymers

Authors: Surkina A. K., Konnova S. A., Fedonenko Y. P.

It is well known that lipopolysaccharides (LPSs) from outer membranes and capsular polysaccharides of Gram-negative bacteria activate in- nate immune system of humans and mammals and can produce septic shock clinical signs. A beneficial effect of LPSs consists in moderate stimulation of production of endogenous mediators by immune system cells, thus increasing the resistance of the organism to infections. In this respect the development of non-toxic derivatives of bacterial glycopolymers with improved immunostimulary properties becomes urgent.

Screening of Genus Azospirillum for their Ability to Produce Extracellular Lignin-Peroxidase and the Degradation of Model Lignin Compounds and Azo Dyes

Authors: Petrov S. V., Kupryashina M. A., Glinskaya E. V., Nikitina V. E., Ponomarova E. G., Vorobyova S. A.

Lignin peroxidase is one of the main enzymes of fungi decomposers of wood, that is capable to many non-specific oxidation of aromatic and polycyclic compounds. By the beginning of our research there were virtually no data of the bacteria’s ability to produce the lignin peroxidase. Rather recently lignin peroxidase activity was detected by us in the washouts from the surface of the bacterial cells and in intracellular extracts of bacteria from genus Azospirillum.

Community of the Aerobic Bacteria-destructors of DDT as a Result of Natural and Artificial Selection

Authors: Andreev D. N., Buzmakov S. A., Demakov V. A., Farofonova V. V., Egorova D. О.

For 40 years the soil microflora of the Landscape Reserve «Osinsk Forest Summer House» (Perm region, Russia) was exposed to high concentrations of DDT. Soil from the blocks 11 and 32 were selected and used in the process of artificial selection of aerobic bacterial communities capable of degrading DDT. Selection was carried out in the laboratory in four stages. As a result, successional changes were recorded, accompanied by reduction in the number and diversity of morphological types of bacterial strains in microbial communities.

Features of Growth and Development of Wheat Seedlings (TriticumaestivumL.) under the Action of 2,4,6-triphenyl-3,5-dichloropyridine and 2,6-diphenyl-3-chloropyridine

Authors: Korobko V. V., Pchelintseva N. V., Luneva M. А., Samsonova Е. А.

A biological testing of new synthetic heterocyclic compounds – 2,4,6-triphenyl-3,5-dichloropyridine and 2,6-diphenyl-3-chloropyri- dine differing more halogen atoms and phenyl fragments of the pyri- dine ring. The compounds were first obtained at the Department of Organic and Bioorganic Chemistry National Research Saratov State University. The objects of the study were the seedlings of spring wheat TriticumaestivumL. The test solutions had a positive effect on the rate root-maintenance seedlings in all variants of the experiment.
