The accumulation of toxicants in the body of bees and honey in the conditions of ecologically crisis areas of the Republic of Tatarstan The article is devoted to the study of contamination of honey bees and honey toxicants in oil-producing regions of the Republic of Tatarstan. The results of the accumulation of a number of toxicants in the body of bees and honey.

Monitoring of mushrooms Agaricus bisporus (J. Lge) Imbach: diagnostics and prevention of diseases We conducted research and experiments and we determined that the mushrooms (Agaricus bisporus (J. Lge) Imbach) infected with bacteria, viruses, microscopic fungi. We recommend prevention activities to fight infections.

The comparison of standard metabolic rate and respiratory quotient in Eurasian blue tit (Cyanistes caeruleus, Aves) during winter and summer Standard metabolic rate in the Eurasian blue tit during winter significantly lower than during summer. Respiratory quotient in the Eurasian blue tit during winter higher than during summer, but not significantly. Standard metabolic rate and respiratory quotient had well pronounced diurnal rhythms with minimum in the nighttime (from 2 a. m. to 5 a. m.) and maximum in the daytime. The maximum difference between standard metabolic rates during daytime and nighttime was 45 % during winter and 15 % during summer.

The effect of foliar feeding of micronutrients on the formation yield of spring rape seeds One of the promising directions in improvement of technology of cultivation of spring oilseed rape is the application of microelements. The results of the studies have revealed increasing the yield of spring rape seeds by 19.7 % with foliar feeding is examined boric and sulfur fertilizers.

The study of the allelic state of microsatellite loci of sugar beet (Beta vulgaris L.) The results of studies of the genetic polymorphism in varieties and hybrids of sugar beet, of which several were polymorphic, are presented. Five types of alleles at marker 086 GZM were identified and analyzed using SSR-analysis. Established genetic similarity between two pairs of hybrids through the test locus, may indicate their common origin.

Bayesian analysis of 2?2 contingency tables relative proportions A new standard expression for distribution of epidemiological risk ratio estimates has been found out using two by two methods of study. Comparing homogeneous groups the distribution is operational within wide-ranging conditions studying both rare and frequent events. Support value of the distribution formula will increase primarily in cases with small amount of the cases or controls observed. Using the derived distribution excess mortality from lung cancer of the Mayak PA workers was associated with radiation exposure with high reliability of the observation.

The comparative study of the influence of pathogenic factors on the formation of congenital and acquired neurosensory hearing loss The aim is to carry out a comparative analysis of pathogenic factors influence on the formation of congenital and acquired NHL and on the formation of complex pathologies and peculiarities of psycho-physiological status of the child. Сhildren with NHL have a physical developmental lag in the process of individual ontogenesis, which is manifested in the lack of functional maturity of somatic and visceral systems of the body, the simultaneous presence of different of anomalies of growth and development. The comparative analysis of the influence of the environmental pathogenic factors on the formation of the congenital and the acquired NHL showed that the condition of intra- and inter-hemispheric integration and the nature of spectral power density of the EEG ranges in children with NHL can act as a functional criterion for the pathology development.

Problems and prospects of the main biogenic elements intramolecular isotope correlations using as a new resource of different aetiology pathologies diagnostics It is shown that chemical elements isotopes fractioning in chemical and biochemical reactions is based on two fundamental kernel properties — the mass and the spin; differences between them can affect on both chemical reactions speed and reactive systems energy state. In some cases deviations in mass-dependent linear isotopic effect for most of uneven isotopes from hydrogen to uranium are observed. These fractioning peculiarities can be used: in living organisms — for early disease detection of different aetiology pathology; in abiogenous natural systems — for new methods of heavy elements isotopes enrichment development.

Formation of the liver in amphibian larval period on the example of the green toad (Bufo Viridis Laurenti, 1768) Describes the morpho-physiological characteristics of the emerging liver in larvae of the green toad (Bufo viridis Laurenti, 1768). Identified that studied the body performs the function of blood during larval development period. In the liver are formed elements of the blood of all lines. Describes he specifics of the organization and morphological changes of the body from developing larvae. There are some pathological changes in the liver and formed elements of blood.

Kasatik mistrue (Iris notha Bieb.) in Azov district of Rostov Province Results of the two Iris notha Bieb. cenopopulations studies in Azov district of Rostov Province in a valley of Vodinskaja gorge (river Tchumburka bassin), first registered in 2014 are presented. There are determined: population area, quantity, density, age structure of cenopopulations, seeds productivity, limiting factors.

Communication quantitative chromosomal abnormalities of spermatozoa and preimplantation embryos Modern genetic diagnosis allows to establish chromosomal nondisjunction not only in postnatal and prenatal periods, but also in germ cells and early embryos. Thus, the most common nondisjunction in sperm are 18 and sex chromosomes. The most common aneuploidy in preimplantation embryos are chromosomes 21 and 18. Win abnormal embryos was 65,2 %, which indicates that the most effective elimination of nonviable embryos in early preimplantation stage.

Characteristics of regenerative processes in the reproductive system of cows in disadvantaged on viral leukemia farms Reproduction of the herd at the epizootic troubles is a challenge for many farms. Special therapeutic approach to gynecological pathology is required for detection of viral bovine leukemia.
