Reprogramming of somatic cells to the phenotypic state termed "induced pluripotency" is thought to occur through three consecutive stages: initiation, maturation, and stabilisation. The initiation phase is stochastic but nevertheless very important as it sets the gene expression pattern that permits completion of reprogramming; hence a better understanding(More)
At the active developmental phases (up to 2 days) cells of toxigenic and nontoxigenic corynebacteria form extracellular vesicle-like material of two types which can be revealed both on whole cells set off by metal and stained negatively, and in ultrathin sections. Extracellular material of the first type is a derivative of an extensive membranous coat of(More)
In recent years, the number of organ-sparing operations for renal tumors has been increasing steadily due to comparable oncological outcomes and the desire to preserve functioning renal parenchyma. Another technique, which is becoming increasingly popular, is so-called zero ischemia partial nephrectomy, which allows bleeding to be controlled during the(More)
Results of the conducted study showed that naturally acquired antibacterial and postvaccinal antitoxic antibodies against diphtheria were found in human blood sera. Challenge of ADT-M toxoid to adults resulted in production of antitoxic as well as antibacterial antibodies in high concentrations. In response to challenge of ADT-M toxoid simultaneously with(More)
A method for isolation of immunochemically active proteins from Corynebacterium diphtheria membranes was elaborated. The proteins were solubilized with the nonionic detergent NP-40 and gel-filtered through an Ultrogel AcA-34 column under denaturating conditions. The purified proteins (Mr = 64 kD) were antigenically active in a solid phase radioimmunoassay(More)
Corynebacteria, being ancient symbionts of open cavities of human body, carry unique, balanced immunogenic stimuli, formed in the process of evolution, thus maintaining non-specific resistance at a certain level. They favor formation of human microcenotic communities as a normal biological and physiological phenomenon. Codivak, a preparation of natural(More)
In this investigation lymphocytes sensitized with Corynebacterium diphtheriae antigens obtained from carriers and convalescents were used. The new diphtheria bacterial vaccine Codivac, in contrast to other comparable preparations (diphtheria toxoid, staphylococcal toxoid, staphylococcal vaccine, levamisole), was found to produce a more direct effect by(More)
The enzyme immunoassay system (EIA) for differentiation of antibodies in therapeutic heterogeneous antitoxic serum and antibodies to Corynebacterium diphtheriae toxigenic strains in patients and carriers was developed. The use of EIA permitted the dynamic evaluation of the characteristics of humoral antitoxic and antibacterial immune response in 50 patients(More)
