Results of intensive phase tretament of tuberculosis treatment according to CYP2E1 genotype

The polymorphism of the gene of cytochrome P-450 2E1 (CYP2E1) that participate in metabolism of antituberculosis agent isoniazid may influence on effectiveness of tuberculosis (TB) treatment. Aim of research: to detect the peculiarities of pulmonary TB course and outcome after in -patient treatment according to CYP2E1 genotype of the patients with primary TB. Materials and methods: analysis of medical cards from 86 patients with primary pulmonary tuberculosis at the end of hospital treatment in Odessa regional antituberculosal dispensary was conducted in 2012 year with consideration of CYP2E1 genotype. Results: the obtained data has proved that at the beginning of treatment there was no significant difference between TB patients concerning the signs of destruction, infiltration and disintegration according to CYP2E1 polymorphism, however the patients with CD, DD genotype more frequently had sings of dissemination and destruction in pulmonary tissues than the patients with CC genotype. At the end of in-patient treatment the patients with CD, DD genotype more often exhibited signs of infiltration of pulmonary tissues and longer remained smear-positive according to cultural method, than the patients with CC genotype. Despite of CYP2E1 genotype around 25% of tuberculosis patients had multidrug resistant strains of M.tuberculosis in the end of in-patient treatment. It will be important to check in coming researches an influence of CYP2E1 polymorphism in TB-patients on toxicity of antituberculosis therapy

A RECONFIGURABLE METASURFACE IN THE FORM OF A FABRY-PÉROT RESONATOR, INVOLVING SEMI-TRANSPARENT MIRRORS AND A NONLINEAR DIELECTRIC INSERT

Subject and Purpose. The paper is aimed at suggesting ways for implementing electromagnetic devices that would involve a nonlinear dielectric inside the structure for concentrating electromagnetic field within it at relatively low intensities of the excitation field. A representative example is offered by a Fabry-Pérot resonator with semi-transparent mirrors and a nonlinear dielectric inside. Methods and Methodology. The paper presents a fundamentally new approach to controlling the frequency response of a metasurface, and a method for protecting electronic modules from high excitation powers. The method is based on the use of nonlinear properties of a Fabry-Pérot "resonator-capacitor" containing a nonlinear dielectric in its volume. Thus, we propose a method for creating spatial filters and antenna protecting fairings capable of active reconfiguration. Results. Analysis of the results has shown that by changing the voltage across the resonator-capacitor plates it is possible to control the degree of electromagnetic field localization in the resonator volume. The frequency response of the metasurface based on the Fabry-Pérot resonator with a nonlinear dielectric inside can be reconfigured by changing the voltage applied to the resonator mirrors. The advantages provided by electrical control of the frequency-selective characteristics include an increased efficiency and possibility of integrating digitally controllable systems into antennas. Conclusions. The use of a Fabry-Pérot "resonator-capacitor"model, with a nonlinear dielectric inside, in the capacity of a reconfigurable metasurface, else as a power limiter in a variety of devices, has sufficient prospects for application in microwave transmitting systems. A special area of application for the reconfigurable Fabry-Pérot resonators is creation of broadband receive antenna systems for direction- finding. In essence, the proposed Fabry-Pérot resonator is a reflective antenna array with an ability to exhibit, conceal or alter its electrodynamic properties according to a certain algorithm. This opens up prospects for its application in "friend-or-foe" recognition systems, reflective beacons, navigation systems, etc

Assessment of ecotoxicological hazard and risk of contamination of groundwater with different groups of pesticides.

The aim of our work was to determine ecotoxicological risk of herbicides, insecticides, fungicides of different chemical classes with different mechanisms of action by the method of Melnikov M.M. and leaching potential index by the method of Sergeev S.G. and co-workers. It was established that in soil and climatic conditions of Ukraine ecotoxicological hazard of studied herbicides by (1-6) orders of magnitude, fungicides – by (3-5) orders, insecticides – by (2-3) orders lower than DDT. The least ecotoxic are herbicides of the last generations, then fungicides and the most ecotoxic are insecticides and herbicides of the old first generations. It was proved the high danger of groundwater contamination with studied herbicides, insecticides and fungicides, except for mesotrione, the application of which has moderate danger in the soil and climatic conditions of Ukraine. It was shown that in soil and climatic conditions of Ukraine, ability of migration from the soil into groundwater of metribuzin, thiamethoxam, paclobutrazole is high, topramezone and mesotrione – moderate, for other substances – low; in terms of hygienic standards in the ground itallows to avoid them getting into the soil flow and minimize the danger of groundwater contamination to public healt

Replication timing in Drosophila and its peculiarities in polytene chromosomes

Drosophila melanogaster is one of the popular model organisms in DNA replication studies. Since the 1960s, DNA replication of polytene chromosomes has been extensively studied by cytological methods. In the recent two decades, the progress in our understanding of DNA replication was associated with new techniques. Use of fluorescent dyes increased the resolution of cytological methods significantly. High-throughput methods allowed analysis of DNA replication on a genome scale, as well as its correlation with chromatin structure and gene activi ty. Precise mapping of the cytological structures of polytene chromosomes to the genome assembly allowed comparison of replication between polytene chromosomes and chromosomes of diploid cells. New features of replication characteristic for D. melanogaster were described for both diploid and polytene chromosomes. Comparison of genomic replication profiles revealed a significant similarity between Drosophila and other well-studi ed eukaryotic species, such as human. Early replication is often confined to intensely transcribed gene-dense regions characterized by multiple replication initiation sites. Features of DNA replication in Drosophila might be explained by a compact genome. The organization of replication in polytene chromosomes has much in common with the organization of replication in chromosomes in diploid cells. The most important feature of replication in polytene chromosomes is its low rate and the dependence of S-phase duration on many factors: external and internal, local and global. The speed of replication forks in D. melanogaster polytene chromosomes is affected by SUUR and Rif1 proteins. It is not known yet how universal the mechanisms associated with these factors are, but their study is very promising

Clusterization in the shape isomers of the 56Ni nucleus

The interrelation of the quadrupole deformation and clusterization is investigated in the example of the 56Ni nucleus. The shape isomers, including superdeformed and hyperdeformed states, are obtained as stability regions of the quasidynamical U(3) symmetry based on a Nilsson calculation. Their possible binary clusterizations are investigated by considering both the consequences of the Pauli exclusion principle and the energetic preference

Інформаційна технологія оптимізації мережі моніторингу стану підземних вод з використанням генетичного алгоритму

Groundwater level monitoring networks can provide significant information about water resources in certain area. Cost effective network design is very important for the management. Maintenance cost of the existing monitoring network can be reduced by minimizing the number of the monitoring wells which do not provide useful information or this information can be reproduced. Finding the group of wells, where measurements could be estimated with the lowest error may be a combinatorial problem as there are many possible combinations to check. Genetic algorithm has a great potential for solving such problems because the time spent searching for a satisfactory solution may be less than the time spent for an exhaustive search, but it does not guarantee the optimal result. In this paper we consider the computational scheme for optimizing existing groundwater monitoring network located in Kryvyi Rih, Dnipropetrovsk region, Ukraine, using genetic algorithm based on ordinary kriging technique and inverse distance weighting method. To find the groups of the redundant wells Python application for the network design optimization was developed. The solution was found for the network with 46 monitoring wells. The number of wells to remove was set from 3 to 7. In terminology of the genetic algorithm each possible solution candidate is called a «chromosome». Chromosome is characterized by a set of values known as «genes». In our case, chromosome is a set of monitoring wells. Iteration of the algorithm is called a «generation». Every generation produced the group of possible solution candidates called a «population». Ordinary kriging technique and inverse distance weighting method were used to estimate the measurements for the candidates. Based on actual and estimated values root-mean-square error for each candidate was calculated. Selection was applied to each population to find the candidates with the smallest error and pass them to the next generation. Single-point crossover was used to exchange genes among chromosomes. To maintain diversity within the population procedure known as «mutation» was applied. Mutation occurred for each gene in the chromosome with the 10% probability. In case of mutation, the gene was replaced by a random one not already included in the chromosome. The number of generations was predefined. Based on the results further development of the tool for the groundwater level monitoring network optimization is planned.Рассмотрена вычислительная схема оптимизации сети мониторинга состояния подземных вод с использованием генетического алгоритма на основе кригинга и метода обратных взвешенных расстояний.Розглянуто обчислювальну схему оптимізації мережі моніторингу стану підземних вод з використанням генетичного алгоритму на основі крігінгу та методу обернено зважених відстаней.Розглянуто обчислювальну схему оптимізації мережі моніторингу стану підземних вод з використанням генетичного алгоритму на основі крігінгу та методу обернено зважених відстаней
