The role of the neuroendocrine system in the development of cell-mediated immunity has been studied in fetal rats. The spontaneous and mitogen-induced proliferation of liver lymphocytes and thymocytes was evaluated in vitro in rats at the 22nd prenatal day following surgical ablation of the forebrain (encephalectomy) or of the entire brain and pituitary(More)
BACKGROUND New high-throughput sequencing technologies promise a very sensitive and high-resolution analysis of DNA methylation patterns in quantitative terms. However, a detailed and comprehensive comparison with existing validated DNA methylation analysis methods is not yet available. Therefore, a systematic cross-validation of 454 sequencing and(More)
The identification of aberrantly hypermethylated genes may lead to the development of new diagnostic markers and the identification of novel targets of epigenetic therapy in myelodysplastic syndromes (MDS). We therefore investigated the methylation status of transcription factor genes KLF5, KLF11, and MAFB, shown to be aberrantly methylated in myelogeneous(More)
The detection of antibodies to Core-antigen of virus of hepatitis C in test-systems for solid-phase immune-enzyme analysis with low optical density can be a result not only of true availability of antibodies but an effect of nonspecific reaction of blood serum. The diagnostic possibilities of immunochips to be used in immune-enzyme analysis for verification(More)
AIM Comparison of alpha-fetoprotein (AFP) levels in blood sera samples of women in the early stages of pregnancy with positive or indeterminate results of anti-HCV. MATERIALS AND METHODS Blood sera samples of women in the first trimester of pregnancy were analyzed by using microplate test systems for enzyme immunoassay (EIA) with complex and separate(More)
The production of interleukin 1 (IL1) by peritoneal and splenic macrophages from rats with adjuvant-induced arthritis on day 17 postadjuvant treatment was not altered compared with normal. Treatment of arthritic rats with beta-carotene reduced hind paw swelling and significantly increased ability of macrophages to secrete IL1 as well as stimulated(More)
The purpose of the study was to elucidate whether hepatitis C virus (HCV) RNA was present in the blood of patients from a Moscow therapeutic-and-prophylactic institution with uncertain results of a study of anti-HCV that were obtained using the algorithm developed for mass screening. The two-stage scheme of testing the serum for anti-HCV, which was(More)
cytes, while its activity towards neutrophils increases considerably. It can be concluded that the catabolism of CRP in the focus of inflammation gives rise to products with new immunoregulatory properties. Free subunits can be regarded as endogenous pH-dependent immunoregulatory agents, which differ from native CRP in a greater selectivity towards(More)
The role of transport activity of Acholeplasma laidlawii plasmatic membrane in the development of resistance to ciprofloxacin and tetracycline was investigated. It was shown that one of the important steps of resistance development in acholeplasms is a complex of adaptation metabolic reactions providing limited antibiotic accumulation by the cells. In the(More)
