A highly sensitive test system, based on the immuno-PCR method, was developed for the detection of two staphylococcal toxins: enterotoxin A (SEA) and toxic shock syndrome toxin (TSST). A key element of the developed systems was to obtain supramolecular complexes of bisbiotinylated oligodeoxynucleotides and streptavidin, which were to be used as DNA-tags.(More)
Studies of collagen gene polymorphisms associated with predisposition to early recurrent miscarriages revealed significant differences in the distribution of COL1A1 C-1997A C>A (rs1107946) genotypes and alleles in the group of pregnant patients with early miscarriages in comparison with controls (normal pregnancy). Identification of COL1A1 C-1997A C>A(More)
mRNA of genes (tgfβ, il6, il10, il1β, and vegf165) involved in cell proliferation, inflammatory, anti-inflammatory, and angiogenic processes were detected and quantified in cultures of mesenchymal stromal cells of different passages derived from human extraembryonic tissues (amniotic sac, umbilical cord, chorionic villi and trophoblast of the placenta). The(More)
A Haemophilus influenzae gene encoding a protein with high homology to ArcB receptor protein from Escherichia coli has been cloned. An error in the previously reported sequence of this gene has been found, thus increasing its open reading frame. The cloned gene comprising the entire open reading frame restores oxygen-dependent regulation of succinate(More)
Previously we demonstrated that the resection of primary 4T1 tumors only slightly prolongs mouse survival, but importantly, creates a “window of opportunity” with attenuated suppressor cell and increased activated T cell populations. This suggests that additional activation of the immune system by immunostimulatory agents during this period may enhance(More)
We studied the relationship between the levels of protamines 1 and 2 (PRM1 and PRM2) and fertilin-β (ADAM-2) mRNA expression and outcomes of infertility treatment using assisted reproductive technologies was studied. Analysis of the relationships between the outcomes of in vitro fertilization and embryo transfer and profiles of the expression of seminal(More)
We propose a method of quantitative functional activity assessment in cells isolated via sorting on a flow cytometer. We show that cell populations vary in the mRNA expression of cytokine genes immediately after isolation and sorting, while the maintenance of homogenous populations in culture without stimulation results in an increase in these gene mRNA(More)
Aneuploidies as quantitative chromosome abnormalities are a main cause of failed development of morphologically normal embryos, implantation failures, and early reproductive losses. Preimplantation genetic screening (PGS) allows a preselection of embryos with a normal karyotype, thus increasing the implantation rate and reducing the frequency of early(More)
According to the results of analysis of whole genome sequencing, the presence of genes having resistance to β-lactam antibiotics in hospital-associated strains of Klebsiella pneumoniae was studied. The strains were isolated from neonatal intensive care units. The data obtained were compared with the results of antimicrobial susceptibility testing of(More)
