PHENETIC ANALYSIS OF POPULUS NIGRA, P. LAURIFOLIA AND P. × JRTYSCHENSIS IN NATURAL HYBRIDIZATION ZONE
Authors: Klimov A. V. , Proshkin B. V. 
Published: July 2018

The wide spread of hybridization in the genus Populus, including spontaneous hybridization, caused by cultivars, requires studying the variability and inheritance of morphological traits by hybrids for initial tracking of these processes. The analysis of endogenous, intra- and inter-population variability was performed on 533 individual poplar trees in seven populations of P. nigra, seven populations of P. laurifolia and four populations of P. × jrtyschensis in the Tom river basin. On each specimen, 15 leaves from short mid-crown branches were collected to determine the shape of the leaf blade, the shape of its tip and base, as well as the branch morphotype. Some biometric indicators were proposed for geometric assessment of the leaf blade shapes of poplar species. The analysis showed that of all the traits examined only the leaf blade shape did not meet the criterion for “phene”, since it is usually represented by several forms in the crown of one and the same tree. In all the species studied, the level of their intra-population diversity was found to be much higher than the inter-population one. According to the increase of intra-population variability of qualitative traits, the taxa could be ranked as P. nigra < P. laurifolia < P. × jrtyschensis. The share of inter-population diversity differed among the species studied, accounting for 21.5% in P. laurifolia, 13.8% in P. nigra and 8.0% in P. × jrtyschensis. The P. laurifolia populations showed the greatest inter-population differentiation, most likely because of a disjunct distribution due to narrow specialization to the montane river environment. The lower differentiation in P. nigra is probably due to the facts that this species dominates the poplar stands of the Tom River basin; its populations are not fragmented and are linked by vast gene flow. In P. nigra, an increase in the diversity of qualitative characteristics and phenotypes was observed in populations confined to hybridization centers. Natural selection is most likely the factor governing the inter-population differentiation in P. × jrtyschensis, leading to the predominance of F1 hybrids in populations and hence to a sharp decrease in inter-population variability.

CRIME AS AN OBJECT OF INQUIRY IN RUSSIAN CRIMINALISTICS ALEKSEY BESSONOV,
Authors: Bessonov A. 
Published: July 2018

This article deals with the definition of the subject and objects of modern Russian criminalistics. It is aimed at sensitizing world public opinion to the necessity of inquiry into the criminalistic essence of crime and encouraging criminalists to study new techniques of crime investigation in order to mitigate risks and reduce errors arising in the criminal investigation process.One of the main objects that is constantly undergoing research in Russian criminalistics is criminal activity. The subject of Russian criminalistics is the regularities of criminal activity. When investigating crimes scientists are interested in the information that allows the successful investigation of the crimes and determination of the offender. The information about different types of crimes, which is necessary for crime investigation, is accumulated in the criminalistic characteristic of crimes. The Criminalistic Characteristic of Crimes is a scientific theory of modern Russian criminalistics that makes it possible to fully examine the specific features of crimes of all kinds, i.e. the forensic nature (essence) of crime, the system of crime elements with their characteristics, and the relationship between those elements. In U.S. and European criminalistics, the regularities of criminal activity are not defined as an object of study of this science. Yet, in the U.S. and European countries criminal profilers investigating criminal cases study the criminal links between crimes to identify crime series and crimes committed by similar offenders (or to determine co-offenders).
EXPERIENCES OF LEGAL INTEGRATION AND RECEPTION BY THE BRICS COUNTRIES: FIVE PASSENGERS IN A BOAT (WITHOUT A DOG)
Authors: Zakharova M. , Przhilenskiy V. 
Published: July 2018

This article assesses the problems and prospects of the development of cooperation among the BRICS countries’ in the sphere of law and the movement of these countries towards the creation of a common legal framework. The article presents a comparative analysis of the systems of law, including the cultural, historical, social and political contexts of their formation and development as well as the functioning of the systems in the conditions of the modern world.The article particularly focuses on the subject of a common philosophy of law for the BRICS countries that would allow not only to establish the interaction of such dissimilar partners in the legal sphere, but also to move towards a new model of legal interaction for the whole world that has embarked on the path of globalization. Special means allowing the assessment of the possibility of future legal integration and globalization based on a common philosophy of law are the traditions and values of the civilizations represented by the BRICS countries. The article suggests that the core of the civilizational and value- based identity of each BRICS partner consists in a set of ideas and interpretations of the notion of justice clearly manifested in the controversy with the theory and ideology of justice proposed by the initiators and leaders of globalization - the countries of the West led by the United States. The theory and ideology of justice promoted by the "Atlantists" is concisely formulated in the book "A Theory of Justice" by John Rawls. Therefore, the reaction to and discussion of such a theory by the philosophers and jurists from Russia, India and China allows determining the contours of the common philosophical and legal position of these countries as well as outlining its significance for the future of the BRICS countries and, perhaps, of the whole system of legal relations in a new globalizing world.
Mechanisms and Drug Targets for Pancreatic Cancer Chemoprevention
Authors: Dhar Deepanshi , Raina Komal , Agarwal Rajesh 
Published: July 2018

Background:
Pancreatic cancer management remains a major challenge to society.
Poor prognosis results in dismal patient survival rates and quality of life post chemo/radiation
therapies. Although progress has been made in drug development for targeting pancreatic cancer,
accompanying issues of drug resistance renders it futile. While intake of fruits and vegetables
in routine diets has been linked to reduced risk of pancreatic cancer, a wide variety of natural
agents are being evaluated as adjuvant therapies in combination with frontline chemotherapeutics
in pancreatic cancer clinical trials.

Objective:
This review highlights the emerging area of cancer chemoprevention with natural/
dietary compounds serving as novel agents possessing strong anticancer properties; these
are pleiotropic agents targeting multiple pathways with minimal toxicity in normal tissue.

Methods:
We employed extensive literature search and considered all the relevant information
presented in a concise, well-balanced and structured format.

Results:
Completed and ongoing human studies with natural agents have shown surprisingly
successful rates for regulating pancreatic carcinogenesis. Combinatorial therapies with synthetic,
approved drugs and natural agents not only improved the patient response rates, but also
helped in overcoming drug resistance and inducing chemosensitivity to the resistant tumors, as
opposed to monotherapies for pancreatic cancer chemoprevention.

Conclusion:
The current review focuses on the available chemotherapeutic drugs and their
limitations, and moves on to discuss the wide realm of chemopreventive efficacy that the natural
agents have to offer. It discusses the underlying mechanisms of action and available information,
from extensive literature analysis, to highlight the novelty of these agents for their antitumor
effects against pancreatic cancer.
Silver Nanoparticles-Chitosan Composite Embedded Graphite Screen-Printed Electrodes as a Novel Electrochemical Platform in the Measurement of Trace Level Nitrite: Application to Milk Powder Samples
Authors: Patri Suma B. , Adarakatti Prashanth Shivappa , Malingappa Pandurangappa 
Published: July 2018

Background:Nitrites can exert acute toxic effects in humans. It is widely used as a preservative in dairy and meat products. The nitrites form N-nitrosamines, which are potential carcinogens and cause detrimental health effects. Herein we report a disposable graphite screen-printed sensor developed using silver metal nano particle embedded chitosan composite in the quantification of nitrite at trace level.Methods:Conventional methods possess various limitations. Electrochemical methods provide an ideal platform for trace nitrite analysis. The prepared composite has been characterized by UV-Visible spectrometry, SEM, EDS and XRD techniques. The proposed sensor has been fabricated by using graphite screen-printed electrodes through drop coating of the composite material. The redox behavior and its application of the fabricated electrode have been studied using cyclic and anodic stripping voltammetric methods.Results:Graphite screen-printed electrodes after modification have been used to identify the electrocatalytic behavior of nitrite oxidation in an aqueous medium. All the parameters influencing the analytical signal have been optimized and incorporated in the recommended procedure. The proposed sensor has been used to measure the nitrite levels from commercially available milk powder samples and the results have been compared with the standard protocol. The results of the proposed sensor are in good agreement with the standard protocol.Conclusion:Ag metal nanoparticles have been embedded in chitosan matrix and used as a composite material in the chemical modification of graphite screen-printed electrodes. GSPEs are easy to fabricate. They provide wide linear working range i.e. 30 - 1140 µM of nitrite. The sensor is highly stable, reproducible and provides a very low detection limit of 1.84 µM. The method has been applied to measure trace level nitrite from milk powder samples.

Authors: El-Desouky Tarek A. , Elbadawy Samy S. , Hussain Hassan B.H. , Hassan Nilly A. 
Published: July 2018

Objectives:
The present study was prepared to investigate the impact of insect density, adult emergence of Tribolium castaneum on the secretion of Benzoquinones (BQs) consist of methyl-1,4-benzoquinone(MBQ) and Ethyl-1,4-Benzoquinone (EBQ), and accumulation of Aflatoxins (AFs) in wheat flour stored at different periods.

Methods:
Forty grams of wheat flour were put into small glass jars (8 cm diameter and 12 cm length). Then T. castaneum was put in each jars at rates of 10, 20 and 30 unsexed pairs of insect adult. The jars were covered with muslin cloth and the rubber band was fixed to prevent insects to escape. A glass jar without any insects served as the control. The jars lifted on bench in the laboratory for two, three and four months of storage under laboratory temperature conditions (with average 28 ± 20C and 65±5 R.H). The previous design was replicated three times. At the end of each storage period, the jars containing the flour were sieved thoroughly by 40 wire mesh size to separate the insects. The insects have been counted on the other hand wheat flour was prepared to determine MBQ, EBQ and AFs by HPLC methods.

Results:
The results indicated the levels of EBQ higher than MBQ in all infested samples at all insect densities (No. of insect pairs). The concentrations of MBQ in wheat flour released by ten adult pairs (10P) with the three storage periods two, three and four months were 10.42 ± 0.56, 22.38 ± 3.67, 27.06 ± 6.71µg/g, respectively. These results increased with insect densities to (30p) were 39.67 ± 0.10, 63.58 ± 2.35 and 106.24 ± 7.4 µg/g after storage periods two, three and four months, respectively. In addition to the concentrations of EBQ with (10P) were 67.45 ± 3.64, 98.0 ± 6.1 204.66 ± 5.8 µg/g with storage periods two, three and four months, respectively. In case (30P) the levels of EBQ were 376.7 ± 0.87, 570.1 ± 2.11 and 1558.66 ± 10.88 (µg/g). The highest concentration of the BQs 1664.90 ± 11.43 (µg/g) released by T. castaneum achieved with the highest adult emergence (1021 insect adult) and the highest insect density (30p) at four months storage period. In general, AFs levels enhanced with a period of storage and insect densities.

Conclusion:
Levels of the BQs (MBQ and EBQ) increased with an increase of storage periods and insect densities. Therefore, the presence of this insect should be prevented in stored wheat flour reducing AFs contamination is possible by storage for short time and prohibit insects which causes an increase temperature of the flour and moisture, all of which promote production of AFs.
