85 (95% CI 0.72-1.00) for Asian women and 1.15 (95% CI 0.95-1.38) for Indian women. Women who were overweight (aOR 0.93; 95% CI 0.77-1.12) or obese (aOR 0.92; 95% CI 0.74-1.12) had similar odds of blastocyst formation comparing to women with normal BMI. Furthermore, analyses examining combined effects of race and BMI revealed no differences in blastocyst formation among Asian or Indian women with varied BMI categories compared to Caucasian women with normal BMI. CONCLUSION Blastocyst formation did not differ based on race or BMI.ENY2 protein of Drosophila melanogaster was previously discovered and characterized in our laboratory [1, 2]. It was found that ENY2 is a subunit of several multiprotein complexes and connects various stages of gene expression [3-5]. This work is devoted to studying the interaction of ENY2 with RNA helicase MLE. This interaction was confirmed by independent methods. Data indicating that this interaction is conserved in evolution and is important for the functioning of MLE in both sexes were obtained.The results of long-term author's studies of the optical and complex-forming properties of more than 30 synthetic low-molecular-weight fluorophores specific for DNA are described. These studies made it possible to significantly expand the already existing database of properties of such compounds, clarify the ideas about the patterns linking the mentioned properties of fluorophores with their structure, and formulate recommendations on designing new effective DNA-specific fluorophores. The results of these studies can be used, in particular, in the development of new rapid methods for diagnosing various diseases, biotesting of probiotic and antibiotic properties of various products and wastes, etc.Nigrostriatal dopaminergic neurons (DNs), involved in the regulation of motor function, are characterized by a high plasticity. selleck screening library Indeed, at the death of up to 50% of DNs in Parkinson's disease, the survived neurons provide normal regulation. This study was aimed to determine whether the vesicle cycle proteins, syntaxin Ia (Syn Ia), synaptotagmin I (Syt I), Rab5a, and complexins I and II (Cmpx I and II) are involved in the mechanisms of neuroplasticity in the substantia nigra, which mainly contains cell bodies and processes of the DNs. In the neurotoxic models of Parkinson's disease in mice, it was shown that, at the degeneration of up to 50% of DNs, the content of Syt I, Syn Ia, and Cmpх I and II, involved in vesicle exocytosis, does not change in the substantia nigra as a whole but is compensatorily increased in individual survived DNs. Thus, the data obtained in this study suggest that the impairment of motor behavior, which occurs at the death of half of the nigrostriatal DNs, is not caused by the impairment of the production of vesicle cycle proteins in the survived DNs.The in vitro model of serum deprivation shows that the survival of SH-SY5Y neuronal cells is ensured by the intrinsic trophic activity of BDNF loop 4 mimetic GSB-106 (10-7 М), which is comparable to that of endogenous neurotrophin (10-9 М). The analysis of the cell cycle and S-phase showed that GSB-106, similarly to BDNF, induces the cell-cycle arrest in the G1 phase, diminishes the number of cells in the S-phase, reduces the number of apoptotic cells, and does not stimulate proliferation.In the present study we showed that the recombinant analogue of the SLURP-1 protein effectively inhibits the growth of a 3D model of tumors-multicellular spheroids reconstructed from human epidermoid carcinoma A431 cells and human lung adenocarcinoma A549 cells. The combined application of rSLURP-1 with gefitinib (inhibitor of epidermal growth factor receptor (EGFR)) leads to the synergistic antiproliferative effect on spheroids from A431 cells. The results obtained suggest the possibility for design of first-in-class anticancer drugs based on recombinant SLURP-1.Results obtained showed that infection with HCMV prevented the death of THP-1 cells treated with DOX in both active and latent forms of infection. In the presence of mTOR inhibitors (rapamycin and Torin2), the sensitivity of the infected cells to DOX was restored. Rapamycin inhibited the expression of the HCMV protein IE1-p72 and increased sensitivity to DOX. Molecular targets for the creation of new drugs for the treatment of leukemia in patients infected with HCMV were determined.Recombinant analogue of the sea anemone Heteractismagnifica peptide was obtained, and the kinetic parameters of its interaction with mammalian α-amylases were determined. Magnificamide inhibits α-amylases significantly stronger than the medical drug acarbose (PrecoseTM or GlucobayTM). Magnificamide is assumed to find application as a drug for prevention and treatment of metabolic disorders and type 2 diabetes mellitus.In the present work, the APX gene encoding ascorbate peroxidase in the moss Dicranum scoparium was for the first time cloned and sequenced, and a high homology of APX with ascorbate peroxidase genes of the mosses Grimmia pilifera and Physcomitrella patens was shown. The structure of the protein was characterized using bioinfomatics approach, and the activity of the enzyme under abiotic stresses was studied. An increase in the activity of ascorbate peroxidase was detected during desiccation of D. scoparium shoots. When exposed to heat shock, a decrease in the activity of ascorbate peroxidase correlated with a decrease in the expression of APX. Conserved elements, which were found in the structure of ascorbate peroxidase gene and protein, indicate that these sequences are conserved in the plant genome during evolution, in support of the importance of this enzyme in maintaining cellular redox status.PARP 1 alters the wrapping of nucleosomal DNA on the histone octamer, thereby modulating the accessibility of different genome sites to nuclear protein factors. Here, we show that non-structured histone tails are involved in the PARP1-induced structural rearrangements in nucleosomes, facilitate and stabilize them, but do not affect the enzymatic activity of PARP1.This work is dedicated to proving our hypothesis that catecholamines and their metabolites play a crucial role in the development of retinopathy of prematurity, which leads to progressive uncontrollable vascularization in the retina, leading to blindness. The study was performed in an animal model of retinopathy of prematurity, which was achieved by hyperoxygenation in rats on postnatal days 7, 14, 21, and 30. The content of catecholamines and their metabolites in the retina of rats was determined by high performance liquid chromatography with electrochemical detection. It was shown that, in the rats with retinopathy, the content of L-DOPA on days 21 and 30 was decreased as compared to the control, whereas the content of noradrenaline on day 14 life increased compared to the control. However, we did not observe changes in the content of dopamine in the experimental animals relative to the control in any period studied. Given the published data on the involvement of catecholamines in the regulation of vasculogenesis in the retina in normal state, our data on the changes in the catecholamine metabolism in the retina in the model of retinopathy of prematurity can be regarded as evidence of the important role of catecholamines in the pathogenesis of this severe disease.
