    DNA Repair is Involved in Mechanism of Drug Sensibilization to Ionizing Radiation of Different Quality

    Get PDF
    It was shown that chemical compounds inhibit the process of cell recovery irradiated with sparsely and densely ionizing radiations. For both types of radiation, it was demonstrated that the irreversible component of radiation damage increases with increasing in drugs concentration, while the recovery constant, characterizing the probability of recovery per unit time, does not depend on the conditions of irradiation. This means that DNA repair is involved in mechanism of drug sensibilisation to ionizing radiation of different quality, which is associated with the formation of additional irreversible damage but not with damage of recovery processes as it was traditionally suggested. The obtained data indicate the prospects of chemical compounds using after irradiation of cells with ionizing radiations of different quality. Keywords: ionizing radiation, survival, irreversible component, recovery constant, bleocin, doxorubicin, endoxan, fluorourozil, cisplatin

    The study of biological diversity requires a thorough inventory of all groups of organisms, including destructors, among which fungi play a significant role. Discomycetes, a group of orders of fungi of the Ascomycota phylum, require close attention from researchers due to their low level of knowledge. The paper proposes an approach to automating the process of inventory of representatives of this group of orders and presents a prototype of a software package that allows one to identify the presence of fruit bodies of discomycetes in photographs taken in the natural habitat. A feature of the proposed solution is the application of the k-means clustering method, the use of scaled histograms to determine the presence of an image of the fruit body of Discomycetes in this image, and the prospects for using this tool in machine learning are described using neural networks

    Optoacoustic spectroscopy for real-time monitoring of strongly light-absorbing solutions in applications to analytical chemistry

    Get PDF
    AbstractAn optoacoustic technique for solutions of strongly light-absorbing analytes at 0.1–0.01mollβˆ’1 is proposed. The technique is based on the wide-band forward mode detection of temporal profiles of laser-generated ultrasonic pulses (optoacoustic signals). The leading edge of the signal repeats the distribution of the laser fluence in the medium, which makes it possible to determine its optical absorption and investigate its dynamics during a reaction. The range of light-absorption coefficients starts from 1 to 5 and reaches 104 to 105cmβˆ’1. The determination of iron(II) as ferroin shows the possibility of probing 0.1mollβˆ’1 of iron(II), which was not previously achieved for this reaction by optical spectroscopy. To further prove the concept, kinetic measurements for ferroin decomposition at the level of 0.1mollβˆ’1 and at high pHs are performed. The results are compared with spectrophotometry at lower concentrations and show good reproducibility and accuracy of kinetic constants

    Estimation of the Severity of Experimental Tularemia against a Number of Morphometric Characteristics

    Research objective consisted in the development of a unified approach to the evaluation of severity of experimental tularemia disease based on the morphometric analysis. Experimental tularemia infection was morbidized in Guinea pigs, both female and male, using subcutaneous inoculation with virulent tularemia microbe cultures. Subsequent to the results of morphometric analysis, selected was a range of indicators characterizing intensiveness of dystrophy, necrobiotic and necrotic processes, infiltrate changes within cells and tissues of the infected animals to fullest extent, and reflecting a life-support system functioning state adequately. Thus, application of quantitative counting to distinguish the changes in experimental animals, while modeling specific infectious process, allowed for standardization and verification of severity evaluation approach and facilitated increase in quality of experimental investigations

    Domino-type Knoevenagel-Michael-hetero-Thorpe-Ziegler and Knoevenagel-hetero-Diels-Alder interactions using 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide and aliphatic aldehydes as initial compounds have been studied. These reactions have led to 2-amino-3-cyano-4H-pyran and 2H-3,4-dihydropyran derivatives, respectively. It has been shown that the three-component one-pot interaction of 1-ethyl-1H-2,1-benzothiazin-4(3H)one 2,2-dioxide with saturated aliphatic aldehydes and malononitrile proceeds under rather mild conditions and results in formation of 2-amino-6-ethyl-4-alkyl-4,6-dihydropyrano[3,2-c][2,1]benzothiazin-3-carbonitrile 5,5-dioxides with moderate and high yields. At the same time, the yields of target products decrease with the increase of the length of the aliphatic aldehyde carbon chain. In this regard, the use of citronellal allowed us to obtain the product of the three-component interaction with a low yield. To date, there is no information in the literature about the possible application of aliphatic dialdehydes in such three-component interactions. It has been found that the use of glutaric aldehyde results in the synthesis of a new class of bis-derivatives of 2-amino-4H-pyran, in which two fragments are linked by the polymethylene bridge. The use of Ξ±,Ξ²-unsaturated aldehydes in the three-component interaction with 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide and malononitrile was accompanied by decrease in the process efficiency compared to saturated aliphatic aldehydes. The target fused 2-amino-3-cyano-4H-pyran was obtained only when Ξ±-methylcinnamic aldehyde was used in the reaction. A two-component interaction of 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide with citronellal has been also studied. It has been shown that this reaction is stereospecific. It proceeds through domino Knoevenagel-heteroDiels-Alder sequence resulting in a new heterocyclic system – 2,2a,3,4,5,6,6a,8-octahydroisochromeno[4,3-c] [2,1]benzothiazine 7,7-dioxide. The study of the antimicrobial activity of the compounds synthesized has allowed finding compounds with a moderate activity against P. aeruginosa Ρ– C. albicans.Π˜Π·ΡƒΡ‡Π΅Π½Ρ‹ Π΄ΠΎΠΌΠΈΠ½ΠΎ-взаимодСйствия КнСвСнагСля-ΠœΠΈΡ…Π°ΡΠ»Ρ-Π³Π΅Ρ‚Π΅Ρ€ΠΎ-Π’ΠΎΡ€ΠΏΠ°-Π¦ΠΈΠ³Π»Π΅Ρ€Π° ΠΈ КнСвСнагСля-Π³Π΅Ρ‚Π΅Ρ€ΠΎ-Π”ΠΈΠ»ΡŒΡΠ°-ΠΠ»ΡŒΠ΄Π΅Ρ€Π° с участиСм 1-этил-2,1-Π±Π΅Π½Π·ΠΎΡ‚ΠΈΠ°Π·ΠΈΠ½-4(3Н)-ΠΎΠ½ 2,2-диоксида ΠΈ алифатичСских альдСгидов, приводящих соотвСтствСнно ΠΊ ΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Π½ΠΈΡŽ ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄Π½Ρ‹Ρ… 2-Π°ΠΌΠΈΠ½ΠΎ-3-Ρ†ΠΈΠ°Π½ΠΎ-4Н-ΠΏΠΈΡ€Π°Π½Π° ΠΈ 2Н-3,4-Π΄ΠΈΠ³ΠΈΠ΄Ρ€ΠΎΠΏΠΈΡ€Π°Π½Π°.

    The article analyzes dynamics of the volume and annual rate of loan delinquency of the country’s population for intermediate quarter dates, compares default retail credit portfolios with similar portfolio of organizations, and determines the main reasons for appearance of population’s debts before banks. It is concluded that it is necessary for banks to focus on development of their own tools and technologies of payment recovery, related to determination of early problematic debt for the purpose of taking preventive measures for preventing the appearance of past-due debts, which is possible under the condition of investing money assets into own analytical and technological tools. An approach to segmentation of debts and factors that could be used as indicators in the process of accompanying and servicing of credits are offered.peer-reviewe
