New molecular cytogenetic biomarkers may significantly contribute to biodosimetry, whose application is still globally diverse and not fully standardized. In 2011, a new term, chromothripsis, was introduced raising great interest among researchers and soon motivating further investigations of the phenomenon. Chromothripsis is described as a single event in which one or more chromosomes go through severe DNA damage very much resembling rogue cells (RC) described more than 50 years ago.

The treatment of classical phenylketonuria is currently represented by many new methods of disease management. A promising method is the use of the enzyme L-phenylalanine ammonia-lyase (PAL) in various forms. The widespread use of enzyme preparations in therapy is limited by a lack of understanding of the mechanisms and systems of the targeted transport of PAL into certain organs and tissues as a result of the incorporation of a drug into the carrier.

The effect of different doses of long-wavelength UV-A (320 nm-400nm) irradiation on physicochemical and antioxidant characteristics of tomatoes grown on the territory of the Russian Federation was studied. The obtained results show that this kind of processing does not cause deterioration of qualitative parameters of vegetables (texture, color, soluble solids content, titratable acidity). It was established that the total content of phenolic compounds, carotenoids and flavonoids increases (p-value<0.

The effect of three types of polysaccharides (agar-agar, carrageenan, hydroxypropyl methylcellulose) on the activity and stability during storage at given temperature conditions of the enzyme preparation L-phenylalanine ammonia-lyase was studied. It was found that the most suitable storage temperature for encapsulated L-phenylalanine-ammonia-lyase is room temperature up to 25 °C for all samples of capsules from plant polysaccharides. Samples of capsules with agar-agar and hydroxypropyl methylcellulose under different temperature conditions inhibited the decrease in enzyme activity, which in other samples of capsules reached 90% in 6 months of storage.

The results of numerical ignition simulation of pentaerythritol tetranitrate (PETN), cyclotrimethylene trinitramine (RDX), cyclotetramethylene tetranitramine (HMX) and 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) by aluminium (Al) and molybdenum (Mo) films heated by nanosecond laser pulses in a three-layer system: glass-metal-explosive material (EM) are presented. Influence of metal film thickness on the time of EM ignition delay was considered. A non-linier dependence of time of delay of ignition of EM from thickness of a metal film is shown.

Air pollutants and ionizing radiation are well-known carcinogens involved in the pathogenesis of lung cancer, and residents of coal-mining regions are exposed routinely to these agents. Polymorphisms in DNA repair genes may be associated with an increased risk of malignant transformation. We investigated associations between the risk of lung cancer in residents of the coal-mining region and polymorphisms in the genes APEX1 (rs1130409), hOGG1 (rs1052133), XRCC1 (rs25489, rs25487), XRCC2 (rs3218536), XRCC3 (rs861539), ADPRT/PARP1 (rs1136410), XPD/ERCC2 (rs13181), XPG/ERCC5 (rs17655), XPC (rs2228001), ATM (rs1801516), and NBS1 (rs1805794).

Computer-aided simulation appropriately using the method of computational fluid dynamics (CFD) makes it possible to determine the elevated-risk zones of most probable formation of restenosis. The main idea of the method described in our article consists in a possibility of creating by the model of the geometrical shape of the vessel and characteristics of the flow at inlets and outlets the parameters of flow in each point of a vessel. The curves of velocity are used to create the curves of pressure at inlets and outlets, which are used in a CFD model.

Idiotypic and anti-idiotypic antibodies against polycyclic aromatic hydrocarbon in human blood serum are new biomarkers of lung cancer.

Oncotarget

August 2019

Federal State Scientific Institute, Federal Research Centre Coal and Coal Chemistry, Siberian Branch of the Russian Academy of Sciences, Institute of Human Ecology, Kemerovo, 650065, Russia.

Evaluation of epidemiologic risk factor in relation to lung cancer invoked by polycyclic aromatic hydrocarbons has been inconsistent. To address this issue, we conducted a prospective evaluation of new biomarkers for lung cancer classified according levels of idiotypic and anti-idiotypic antibodies against polycyclic aromatic hydrocarbons in human blood serum. The blood serums of 557 lung cancer patients and 227 healthy donors were analysis of these antibodies by ELISA.

By sequencing 523 ancient humans, we show that the primary source of ancestry in modern South Asians is a prehistoric genetic gradient between people related to early hunter-gatherers of Iran and Southeast Asia. After the Indus Valley Civilization's decline, its people mixed with individuals in the southeast to form one of the two main ancestral populations of South Asia, whose direct descendants live in southern India. Simultaneously, they mixed with descendants of Steppe pastoralists who, starting around 4000 years ago, spread via Central Asia to form the other main ancestral population.

The nature of the chemical bond in 31 oxyanionic crystals was analyzed using calculations and quantum theory of atoms in molecules (QTAIM). The QTAIM topological analysis of the calculated electron densities in oxyanionic crystals revealed that some of the metal-oxygen, metal⋯metal, metal-ligand and hydrogen bonds are partly covalent in nature. The covalency criteria for metal-oxygen and hydrogen bonds based on electron densities at the bond critical points were obtained.

The detection of mutations of the gene of UDF-glucuronyltransferase A1 (UGT1A1) has an important practical value. The carriers of mutant genotypes, mainly *28/*28, are characterized by a reduced function of glucuronidation and excretion of a number of endogenous and exogenous toxins. A precise association of particular forms of benign hyperbilirubinemia (especially Gilbert's syndrome) with mutations in promoter and exonic areas of UGT1A1 is established.

The living environment is a multilevel physical and chemical xenobiotic complex with potentially mutagenic effects and health risks. In addition to inorganic exposures, all terrestrial and aquatic living forms interact with microbiota as selectively established communities of bacteria, viruses and fungi. Along these lines, the human organism should then be considered a "meta-organism" with complex dynamics of interaction between the environment and microbiome.
