Abstract
PURPOSE To evaluate biocompatibility of the new keratoprosthesis supporting plates (KSP) in rabbits in vivo. MATERIAL AND METHODS The study included 15 chinchilla rabbits. In the first group (5 rabbit eyes) KSP made of hydrophobic acryl with square penetrating holes of 220×220 micron (model 1) were inserted into rabbits' corneas. In the second group (5 eyes), KSP made of hydrophobic acryl were used that had trapezoidal fenestrations with size (from 170×130 micron to 180×70 microns) gradually changing from periphery to the center of KSP (model 2). The control group rabbits (5 eyes) had 1/2 of Fyodorov-Zuev KSP made of titanium implanted. All animals were observed for up to 3 months with biomicroscopy and optical coherence tomography of the anterior segment. The animals were then euthanized and had their corneo-scleral discs excised and then examined with optical microscopy and scanning electron microscopy (SEM). RESULTS After 3 months, there was only one case of KSP protrusion in the first group. In the second group, thinning of the corneal layers above the central part of KSP occurred in one case. The presence of polymer KSP (of both models) in the corneal stroma was found not to cause formation of rough fibrotic tissue. At the same time, adhered cellular and fibrous elements were discovered on the surface and inside the holes of the polymer KSP, while on the surface of the titanium plate cellular elements were absent. CONCLUSION Supporting plates made of hydrophobic acrylic material can potentially serve as a foundation for the new keratoprosthesis design.

Abstract
Exhaled breath analysis is a novel tool for diagnostics of different diseases. Taking into account the secretory function of the lungs, the composition of exhaled breath is different in physiological and pathological conditions. In this review we consider of some substances which content vary in cardiovascular diseases - pentane, isoprene, carbon monoxide and trimethylamine. Modern technologies allow to move the analysis of exhaled breath from research laboratories into clinical practice. Thus, a new tool for real time of screening various cardiovascular diseases has appeared in the arsenal of physicians.

Abstract
In this paper, we, for the first time, describe the interaction between the butyrylcholinesterase enzyme and echothiophate, a popular model compound and an analogue of the chemical warfare agents VX and VR, at the atomistic level. Competition between the two echothiophate conformations in the active site was found using molecular modeling techniques. The first one is close to the mode of binding of the substrates of choline series (butyrylcholine and butyrylthiocholine) and is inhibitory, since it is unable to react with the enzyme. The second one is characterized by a significantly worse estimated binding affinity and is reactive. Thus, echothiophate combines the features of two types of inhibitors: competitive and suicidal. This observation will help clarify the kinetic reaction scheme in order to accurately assess the kinetic constants, which is especially important when designing new butyrylcholinesterase variants capable of full-cycle hydrolysis of organophosphorus compounds.

Abstract
Aptamers are widely used as molecular recognition elements for detecting and blocking functional biological molecules. Since the common "alphabet" of DNA and RNA consists of only four letters, the chemical diversity of aptamers is less than the diversity of protein recognition elements built of 20 amino acids. Chemical modification of nucleotides enlarges the potential of DNA/RNA aptamers. This review describes the latest achievements in a variety of approaches to aptamers selection with an extended genetic alphabet.

Abstract
It is proposed to perform quantum mechanical/molecular dynamics calculations of chemical reactions that are planned to be catalyzed by antibodies and then conduct a virtual screening of the library of potential antibody mutants to select an optimal biocatalyst. We tested the effectiveness of this approach by the example of hydrolysis of organophosphorus toxicant paraoxon using kinetic approaches and X-ray analysis of the antibody biocatalyst designed de novo.

Abstract
In this research we investigated the response of DNA-modified carbon nanotubes in the presence of thrombin and albumin. We analyzed aptamer-carbon nanotube interactions by Raman spectroscopy and by analyzing resistance after each step of biosensor assembly. We have shown that intensity of G-band decreases due to interconnection of aptamer and carbon nanotube and this also evaluates in decrease of sensor structure resistance. The response of the sensor exposed to thrombin and albumin differs essentially from each other. This fact serves as the prerequisite for the development of a highly selective biosensor. Results of this investigation can be used in creation of new generation of personal health monitoring systems.

Abstract
RA36 DNA aptamer is a direct anticoagulant prolonging clotting time of human, rabbit, and rat plasma in the thrombin time test. Anticoagulant activity of RA36 is lower than that of recombinant hirudin. During inhibition of human plasma clotting activated with echitox (coagulase from Echis multisquamatus venom), the aptamer presumably binds to meisothrombin exosite I. The sensitivity of human plasma to the aptamer 5-fold surpasses that of rat plasma. Analysis of RA36 binding to coagulase of Agkistrodon halys venom (ancistron) is required for proving the effect of aptamer on polymerization of human fibrinogen.

Abstract
Telomere length, an important feature of life span control, is dependent on the activity of telomerase (a key enzyme of the telomere-length-maintaining system). Telomerase RNA is a component of telomerase and, thus, is crucial for its activity. The structures of telomerase RNA genes and their promoter regions were compared for the long-living naked mole rat and different organisms. Two rare polymorphisms in Heterocephalus glaber telomerase RNA (hgTER) were identified: AG in the first loop of pseudoknot P2b-p3 (an equivalent of 111nt in hTR) and GA in the scaRNA domain CR7-p8b (an equivalent of 421nt in hTR). Analysis of TER promoter regions allowed us to identify two new transcription factor binding sites. The first one is the ETS family site, which was found to be a conserved element for all the analyzed TER promoters. The second site is unique for the promoter region of TER of the naked mole rat and is a binding site for the SOX17 transcription factor. The absence of one Sp1 site in the TER promoter region of the naked small rat is an additional specific feature of the promoter area of hgTER. Such variation in the hgTER transcription regulation region and hgTER itself could provide increased telomerase activity in stem cells and an extended lifespan to H. glaber.

Abstract
Modern medicine experiences deficit of inexpensive rapid screening technologies despite progress in the development of diagnostic methods for various diseases. A promising approach is the analysis of exhaled air known to contain thousands of volatile organic substances whose composition differs considerably in health and disease. We isolated certain compounds that may be used as biomarkers of cardiovascular pathology (nitric oxide, carbon monoxide, pentane, isoprene, acetone). There is a variety of methods for the detection of substances in the exhaled air; such as gas spectrography, mass spectrometry, etc. However, ion mobility spectrometry appears the most suitable technique for the purpose of screening studies due to its high speed and sensitivity, small size of the apparatus, and possibility to measure trace amounts of the substances of interest. Possibilities to diagnose lung cancer based on exhaled air composition are considered.

Abstract
For prokaryotes in vitro, 16S rRNA and 20 ribosomal proteins are capable of hierarchical self- assembly yielding a 30S ribosomal subunit. The self-assembly is initiated by interactions between 16S rRNA and three key ribosomal proteins: S4, S8, and S7. These proteins also have a regulatory function in the translation of their polycistronic operons recognizing a specific region of mRNA. Therefore, studying the RNAprotein interactions within binary complexes is obligatory for understanding ribosome biogenesis. The non-conventional RNAprotein contact within the binary complex of recombinant ribosomal protein S7 and its 16S rRNA binding site (236 nucleotides) was identified. UVinduced RNAprotein cross-links revealed that S7 cross-links to nucleotide U1321 of 16S rRNA. The careful consideration of the published RNA protein cross-links for protein S7 within the 30S subunit and their correlation with the X-ray data for the 30S subunit have been performed. The RNA protein crosslink within the binary complex identified in this study is not the same as the previously found cross-links for a subunit both in a solution, and in acrystal. The structure of the binary RNAprotein complex formed at the initial steps of self-assembly of the small subunit appears to be rearranged during the formation of the final structure of the subunit.

Abstract
DNA aptamer RA36 with a molecular weight of 10000 is direct-acting anticoagulant whose efficacy is lower than that of recombinant hirudin and unfractionated heparin (UFH) in blood clotting time (BCT), activated blood recalcification time (ABRT), recalcification time (RT), prothrombin time (PT), and activated partial thromboplastin time (APTT) tests. The anticoagulant effect of RA36 is comparable with that of UFH in the thrombin time (TT) test, but is lower than the effect of recombinant hirudin. Analysis of the blood and plasma anticoagulant activity during intravenous bolus administration of aptamer RA36 in rabbits and rats is based on the use ABRT (in blood case) and APTT/RT (in plasma case) tests. The range of doses for evaluation of pharmacodynamic parameters of RA36 during intravenous bolus administration in rabbits and rats is 3 - 34 mg/kg and 1 - 27 mg/kg, respectively. Accordingly, designed dose range for humans is 1 -29 mg/kg.

Abstract
Two models of 15-mer thrombin-binding DNA aptamer (15TGT) were comparatively analyzed by molecular dynamics simulation using the GROMACS software package. The two original models of 15TGT were obtained by NMR and X-ray analyses. The models significantly differ in the topology of loops and the direction of oligodeoxyribonucleotide chain. The evolution of the two structures in parm99 force fields and parmbsc0 optimized for nucleic acids was analyzed in our adaptation of GROMACS architecture. It is shown that the best system for description of the 15TGT structure is the model obtained by X-ray analysis in the parmbsc0 force field.

Abstract
In this work it is shown by deletion analysis that an intercistronic region (ICR) approximately 80 nucleotides in length is necessary for interaction with recombinant E. coli S7 protein (r6hEcoS7). A model is proposed for the interaction of S7 with two ICR sites-region of hairpin bifurcations and Shine-Dalgarno sequence of cistron S7. A de novo RNA binding site for heterologous S7 protein of Thermus thermophilus (r6hTthS7) was constructed by selection of a combinatorial RNA library based on E. coli ICR: it has only a single supposed protein recognition site in the region of bifurcation. The SERW technique was used for selection of two intercistronic RNA libraries in which five nucleotides of a double-stranded region, adjacent to the bifurcation, had the randomized sequence. One library contained an authentic AG (-82/-20) pair, while in the other this pair was replaced by AU. A serwamer capable of specific binding to r6hTthS7 was selected; it appeared to be the RNA68 mutant with eight nucleotide mutations. The serwamer binds to r6hTthS7 with the same affinity as homologous authentic ICR of str mRNA binds to r6hEcoS7; apparent dissociation constants are 89 +/- 43 and 50 +/- 24 nM, respectively.

Abstract
Trans-translation is a unique process which switches the synthesis of a polypeptide chain encoded by a nonstop messenger RNA to the mRNA-like domain of tmRNA. It is used in bacterial cells for rescuing the ribosomes arrested during translation of nonstop mRNA and directing this mRNA and the product polypeptide for degradation. tmRNA activity is essential for bacterial survival under adverse conditions, quality-control of translation and regulation of certain physiological pathways. This review will focus on recent advances in trans-translation investigation: the details of tmRNA-SmpB interaction and the structure of the early ribosomal complexes will be characterized; the causes for the empty A site appearance in the translating ribosomes, possible mechanisms of the stalled ribosomes recognition and resume codon determination will be discussed, the proteins degraded nonstop mRNA and tagged peptide will be viewed.

Abstract
In E. coli cells ribosomal small subunit biogenesis is regulated by RNA-protein interactions involving protein S7. S7 initiates the subunit assembly interacting with 16S rRNA. During shift-down of rRNA synthesis level, free S7 inhibits self-translation by interacting with 96 nucleotides long specific region of streptomycin (str) mRNA between cistrons S12 and S7 (intercistron). Many bacteria do not have the extended intercistron challenging development of specific approaches for searching putative mRNA regulatory regions, which are able to interact with proteins. The paper describes application of SERF approach (Selection of Random RNA Fragments) to reveal regulatory regions of str mRNA. Set of random DNA fragments has been generated from str operon by random hydrolysis and then transcribed into RNA; the fragments being able to bind protein S7 (serfamers) have been selected by iterative rounds. S7 binds to single serfamer, 109 nucleotide long (RNA109), derived from the intercistron. After multiple copying and selection, the intercistronic mutant (RNA109) has been isolated; it has enhanced affinity to S7. RNA109 binds to the protein better than authentic intercistronic str mRNA; apparent dissociation constants are 26 +/- 5 and 60 +/- 8 nM, respectively. Location of S7 binding site on the mRNA, as well as putative mode of regulation of coupled translation of S12 and S7 cistrons have been hypothesized.

Abstract
Both structural and thermodynamic studies are necessary to understand the ribosome assembly. An initial step was made in studying the interaction between a 16S rRNA fragment and S7, a key protein in assembling the prokaryotic ribosome small subunit. The apparent dissociation constant was obtained for complexes of recombinant Escherichia coli and Thermus thermophilus S7 with a fragment of the 3' domain of the E. coli 16S rRNA. Both proteins showed a high rRNA-binding activity, which was not observed earlier. Since RNA and proteins are conformationally labile, their folding must be considered to correctly describe the RNA-protein interactions.

Abstract
Direct determination of RNA-protein complex structures is often facilitated by the use of thermophilic proteins; however E. coli is the most investigated system so far. A hybrid approach is to form heterologous complexes of E. coli RNA with thermophilic proteins. The rationale for this approach to RNA-protein interactions in ribosomes is based on the ability of the thermophilic protein S7 to replace a homologous counterpart in vivo. In vitro, the protein S7 of Thermus thermophilus is able to form complexes with both the minimal 16S rRNA fragment and the intercistronic region of the str operon mRNA from E. coli (Kd = 1.4 x 10(7) M and 1.1 x 10(-7) M respectively). The interaction of Thermus S7 with the E. coli intercistronic mRNA is surprising, because this region does not exist in the thermophilic str operon. It suggests a high degree of conservation of an RNA-binding site on S7.
