СOMMUNICATION OF PARAMETERS OF HATCHING EGGS WITH HATCHABILITY AND SEX DETERMINATION OF BIRDS

Posted in 2018, BIOLOGY, Issue №12(78) December 2018 | 0 comments

The purpose of this research was to study of effect of periods of storage of eggs before incubation, their shape, mass and density on hatchability, and sex ratio. The increaseof hatchability and early detection of sex determination of young birds create opportunitiesfor differentiation of their keeping and feeding that will help to reduce the cost of poultry products and increase of industry profitability. Interconnection of hatchability and by the studied parameter. Sex of pauls has been determined by Japanese method.According to the results of study of incubation of turkeys eggs have been found that sue to the elongation of shelf life from 7 to 9 days, there was a decrease of hatching of young turkeys from 72.2% to 68.2%; geese eggs with a shelf life from 7-14 days – from 64.6% to 55.2% with ratio change in hatching of females/males from 1.00/.02 to 1.00/1.26 up to 1.00/1.03 and 1.00/1.21 respectively. Hatchability of turkeys’ eggs with weight 80-90 g was 75.4%, geese eggs with weight 140-150 g – 66.7%. Upon gaining in weight of incubated eggs of turkeys from 80 to 90 g and ratio of female/male has been increased from 1.00/0.96 to 1.00/1.11 and geese from 140 to 150 g or more to 1.00/1.06 to 1.00/1.13. When the index of shape of eggs is reduced, the hatching of young birds decreased and density of males increased. The decrease in density also reduced the hatching of young birds, but does not reflect on sex ratio.

INFLUENCE OF ADVANCED GLYCATION END PRODUCTS ON CELLULAR PROCESSES

Posted in 2018, BIOLOGY, Issue №12(78) December 2018, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Advanced Glycation End products or AGEs are formed as the result of non-enzymatic interaction of proteins with carbohydrates and belong to the group of modified amino acid residues that can slowly accumulate in the body during the normal process of aging. In addition to endogenous AGEs, these toxic compounds appear in the human body due to the consumption of food that has been heat treated or subjected to long-term storage, due to active and passive smoking. AGEs can cause the onset and progression of complications of diabetes, and become the basis of the pathophysiology of many other diseases including cardiovascular and neurodegenerative ones. Both exogenous and endogenous AGEs play a significant role in the development of the inflammatory response in the human body. The proposed review examines the structure and functions of the main AGEs receptors and the signaling pathways they activate, as well as some of the biological effects of this activation.

INFLUENCE OF CLIMATIC FACTORS ON THE PHENOLOGY OF FRUIT-TREESNOUT BEETLE RHYNCHITES BACCHUS L. 1758 UNDER THE CONDITIONS OF KABARDINO-BALKARIA

Posted in 2018, BIOLOGY, Issue №11(77) November 2018, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The following article shows that it is necessary to study the phenology of each pest separately for a more successful protection of fruit crops from insect pests. The Coleoptera are the most poorly studied species of the entire class of insects, because it was considered that they did not cause much harm to industrial gardening. The phenology of the insect is poorly investigated, as all the developmental processes of the larvae take place inside the fruit. The period of egg laying and their birth are also poorly covered.

The purpose of the study is:

To experimentally determine under what conditions of the external environment one or another pest developmental stage takes place in the foothill zone of fruit growing in Kabardino-Balkaria.

To achieve the goal, the following tasks were set:

To determine the phenological characteristics of the pest in the study area.
To determine whether climatic factors affect the phenology of the pest.

EFFECT OF HETEROAUXIN AND AMBER ACID ON GERMINATING ABILITY OF WHEAT SEEDS AFTER THEIR DURABLE STORAGE

Posted in 2018, BIOLOGY, Issue №11(77) November 2018, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

There exists the problem of restoring the germination of unique samples, the viability of which has decreased during durable storage in the genetic banks of plants so that they cannot be sown directly in the field. In this work, the effect of heteroauxin (IAA) and amber acid on seed germination of five wheat samples from the VIR collection are investigated, the germination rate of them after 49–50-year storage has decreased to 3.8–47.1%. It is shown that IAA stimulates seed germination on two samples of soft winter wheat. The concentration of 2.5×10-7 M is particularly effective; it increases the germination of wheat seeds by 7.1-8.5%. It is also found that amber acid at a concentration of 5×10–4–10–3 M increases seed germination by 2.3–5.0% on the same samples. IAA or amber acid treatment in different concentrations of the other two samples of soft winter wheat and a sample of durum wheat either do not give an effect or give a negative and sometimes only a small positive effect. The ambiguity of the obtained result does not allow recommending heteroauxin and amber acid to restore the germination of seed samples after prolonged storage.

OBTAINING BACILLUS PUMILUS DELETION MUTANTS FOR PROTEINASE GENES BASED ON CRISPR-CAS9 TECHNOLOGY

Posted in 2018, BIOLOGY, Issue №11(77) November 2018, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Deletion mutant of Bacillus pumilus bacteria with inactivated subtilisin-like proteinase (aprBp) gene was obtained with the help of CRIPSR-Cas9 genome editing technology for the first time. In the course of the work, vector (pToy1.4) was developed for the inactivation of the aprBp gene. It is shown that the efficiency of transformation of the obtained plasmid into B. pumilus cells is very low, which may be due to the presence of phages in the genome of this bacterium, the lack of competence genes, as well as large molecular weight of the developed vector. The strain with the inactivated aprBp gene is of interest for further study because of the fundamental role of this enzyme in B. pumilus cells, as well as in the production of homo- and heterologous proteins.

PROPERTIES OF SOILS IN DEVELOPING TECHNOGENIC CATENAS OF PRIMORSKY KRAI (ON THE EXAMPLE OF PAVLOVSKY COAL DEPOSIT WASTES)

Posted in 2018, BIOLOGY, Issue №11(77) November 2018, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article discusses current problems of determining the main features of soil formation on self-expanding tank wastes. For this purpose, tasks were performed to determine morphological and other properties of the soil. It is established that the main pedogenic transformations occur in the root zone. Transition horizons are difficult to determine during morphological study. This is explained, on the one hand, by the weak development of the processes, and on the other, by the high content of carbonaceous particles in the rocks that form the wastes. The distribution curve of the total organic carbon along the profile is of concave character with a sharp drop with depth (accumulative distribution type). As a result of the illimerization, the minimum content of the fraction of physical clay moves to deeper layers in soils of the subordinate elements of the landscape. At the same time, the content of the sludge fraction increases, which may indicate processes of not only physical, but also of pedogenic disintegration of the rocks composing the waste.

NEW TECHNOLOGY OF PRESERVING THE COLLECTION AND MAIN FEATURES OF AGRICULTURAL TECHNOLOGY OF TULIPS WITHOUT ANNUAL DIGGING BASED ON MANY YEARS’ EXPERIENCE

Posted in 2018, BIOLOGY, Issue №11(77) November 2018, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

We studied the possibility of cultivating the varieties and types of tulips of different origins without digging. The following varieties and types were considered: Three varieties from the garden group of Darwin hybrids – Yellow Dover, Beauty of Oxford, Beauty of Apeldoorn; Princeps from the Foster Tulips group; Little Princess, a hybrid of T. hageri Heldrelch and T. aucheriana Baker; late tulip T. tarda Stapf; tulip of Eichler T. eichleri Regel., tulip of Vvedensky T. vvedenskyi Z. Botsch. We have been taking into account the number of flowering and juvenile plants, their biometric characteristics, determined the number and mass of bulbs, recorded the attack of plants from diseases and pests for three years. It has been established that for the inclusion of tulips in the composition of combined perennial flower beds it is necessary to pay attention to the varietal and specific features. Preference should be given to varieties that are less sensitive to dry dormancy conditions (humidity and temperature during flowering), resistant to diseases, with an average coefficient of biological reproduction and with good growth energy of juvenile bulbs. For flowering uniformity in each year of the growing season, it is necessary, to use medium and small bulbs (or counting ratoon) in addition to large flowering bulbs. It is recommended to use the following types and varieties for long-term flower beds without digging: Late tulip – T. tarda Stapf; Wedenden Tulip – T. vvedenskyi Z Botsch., Little Princess hybrid and variety of Beauty of Oxford.

THE ROLE OF ENDOCIOSIS IN THE PROTECTION OF POLYMORPHONOADERIC LEUKOCYTES WITH HEAT SHOCK PROTEIN HTS70 FROM ENDOTOXIN ACTIVATION

Posted in 2018, BIOLOGY, Issue №10(76) October 2018 | 0 comments

Endotoxins (ET) of bile-tolerant gram-negative bacteria are of great importance in various diseases of mammals; they increase the generation of active forms of oxygen (ROS) by polymorphonuclear leukocytes (PMN). The inducible protein of human heat shock HSP70, when applied extracellularly, reduces ROS production by polymorphonuclear leukocytes induced by ET. It was established that clathrin-dependent and receptor-dependent pathways of Btsch70 endocytosis play an important role in the mechanism of PMNL protection by protein HSP70 from the activation of ET cells.

ALTERNATIVE WAY OF STORING COLLECTION OF GENETIC RESOURCES OF FODDER CROPS

Posted in 2018, BIOLOGY, Issue №9(75) September 2018 | 0 comments

The article analyzes the results of 25-year storage of 575 samples of creeping alfalfa seeds (Medicago sativa L.) and 127 samples of meadow clover seeds (Trifolium pratense L.) in the branch of N.I.Vavilov Research Institute of Plant Industry of the Kuban genetic seed bank at a temperature of 4 °C. Seeds were stored in hermetically sealed containers; the initial moisture content of the seeds was 4.0-6.9%. It was found that 95% of the samples of creeping alfalfa and 93% of clover had germination above 80% after the storage. Clover specimen showed a tendency for the increase in terms of keeping high viability with a decrease in the initial moisture of seeds. In 2018, a method was developed to produce ultra-dry seeds of clover meadow and creeping alfalfa potentially suitable for long-term storage without the use of low temperatures, which is an alternative way to store plant genetic resources. Using silica gel in the ratio of seeds: silica gel = 1:10, in 7 weeks we managed to dry the clover meadow to 2.8%, and creeping alfalfa to 1.9-2.0% without reducing their germination. These values are below the recommended standards for gene banks; such seeds can be referred to as ultra-dry. An important point in the technique is the weekly replacement of the used silica gel with the fresh one. The next stage of the work is to test the effectiveness of this mode of drying the seeds of clover meadow and creeping alfalfa in experiments on long-term storage, as well as in model experiments on accelerated aging of seeds.

ESTIMATION OF INTER-OSCILLATORY COHERENCE IN THE ELECTROENCEPHALOGRAMS BY USE OF THEIR MATHEMATICAL MODELING

Posted in 2018, BIOLOGY, Issue №9(75) September 2018 | 0 comments

In our previous studies, a model of the electroencephalogram (EEG), based on integral nonlinear equations for averaged brain membrane potentials in neuronal ensembles, was developed. In areas of EEG stability, characteristic equations, constructed for a set of oscillations with negative decrements and their convolution with discrete (evenly discontinuous) white Gaussian noise, satisfyingly simulated the EEG. The methods for calculation of the EEG decrements through correlation functions were suggested earlier and tested on EEG from rats and mice. In present study on transgenic 5xFAD mice (a model of the Alzheimer’s disease), we analyze the relationships between different brain areas using coherence of oscillations in their EEG with decrements and frequencies revealed from our EEG model.

NEW TECHNOLOGY OF INFORMATION INTERACTION BETWEEN MAN AND DOLPHIN

Posted in 2018, BIOLOGY, Issue №9(75) September 2018 | 0 comments

We have shown experimentally the promising way to dolphin and man communication using video and acoustic equipment by the beluga dolphins reaction to various scenarios presented. For the demonstration of these scenarios, a special underwater monitor was engineered. The participated animals’ interest to different pictures and sounds revealed itself in a sharp increase of the dolphin retention time at the screen (up to 7 minutes). The animal’s acoustic response to the demonstration of its own image with the use of a web camera consisted of the frequency wideband impulse packets sequences of varying lengths with internal time-pulse modulation. The analysis of the recorded signals made it possible to distinguish three main temporal structures, consisting of repetitions and permutations of such packets in time.
