New nucleic dyes for pico-and nanoplankton cytometric analysis

Flow cytometry (FCM) is a promising tool in the field of aquatic phytoplankton ecology because it allows for multi-parameter assessment of the physiological state of individual cells in an algal population. It can help to elucidate major questions such as phytoplankton taxa identification, the evaluation of cell quantity and viability, and the measuring of phytoplankton and general microbial metabolic activities. Traditionally, microalgal characterization is performed by microscopic analysis using UV-excited nuclear dyes (e.g. Hoechst and DAPI) or dyes that are excited in the blue-green part of the spectrum such as propidium iodide and eosin. The development of multi-laser cytometric systems has widened the possibilities for multi-parametric analysis and cell sorting of phytoplankton populations. Notwithstanding, significant algae autofluorescence originating from different types of chlorophyll and accessory pigments may overlap with propidium iodide and/or eosin staining and affect the resolution of algae clusters and cell sorting

Centralized procurement as a financing tool for innovation and technology entrepreneurship

This article proposes a model of phased financing of innovative projects implemented by small enterprises to market, using the internal "fundraising"of such companies, by participating in centralized procurement procedures under 44-Ф3 and 223-Ф3. The risks of applying such a model of project financing are assessed and the types of procurement procedures are compared with the current legislation of Russia in this area. © Published under licence by IOP Publishing Ltd

Comparative DNA Cytometry of Primary and Recurrent Soft Tissue Sarcomas

The goal of comparative investigation was to reveal the distinctive features of the DNA content and cell distribution in the phases of the cell cycle of recurrent STS. DNA cytometry in the tumor tissue of 30 primary soft tissue sarcomas (t2a-2bn0M0) and 30 STS recurrences (t2-3n0M1) was carried out using the method of flow cytofluorometry. the tumor ploidy and cell distribution in the cell cycle phases were analyzed. Results. A number of differences in the DNA cytometric parameters of primary and recurrent STS have been revealed, they include: an increase in the proportion of aneuploid tumors in case of recurrence, the number of tumors with DNA index within the mitotic cycle, an increase in the proportion of cells in G2+M- phase of diploid and aneuploidy tumors and a decrease in S- phase of aneuploid ones. It has been shown that with a G2 differentiation degree, the proportion of cells in G2+M, S- and IP of recurrent STS is significantly lower than the primary parameters. An increase in the proportion of cells in G2+M- phase and a decrease in the rate of proliferation of recurrent STS, depending on the stage, are shown only in case of stage III. Conclusion. The revealed features of DNA content and cell cycle of tumor cells of soft tissue sarcomas will allow to approach to understanding of biological bases of recurrence of this malignant disease.Целью исследования было выявить в сравнительном аспекте отличительные особенности содержания ДНК и распределения клеток по фазам клеточного цикла рецидивных СМТ.

At the intersection of globalization and "civilizational originality' : cultural production in Putin's Russia

This special issue originates from a transnational collaboration of scholars in philology, comparative literature, social theory, sociology, anthropology, ethnography, and media studies. The collection strives to advance a research agenda built on the nexus of three intellectual and academic domains: post-Soviet Russian cultural studies', the research paradigm put forward by Cultural Studies, as well as empirical methods developed in sociology. The collection illustrates the importance of expanding the experience of Cultural Studies beyond its established spheres of national investigation, while it also speaks to the necessity to re-evaluate the hegemony of the English-language academic and cultural production on the global scale. The collection offers insights into the gamut of cultural practices and institutional environments in which Russian cultural production happens today. It shows how cultural industries and institutions in Russia are integrated into the global marketplace and transnational communities, while they also draw on and contribute to local lives and experiences by trying to create an autonomous space for symbolic production at personal and collective levels. Through diverse topics, the issue sheds light on the agency, i.e. practitioners and participants, creators and consumers, of Russian cultural production and the neoliberal practices implemented on creative work and cultural administration in Russia today. The Introduction outlines the development of academic studies on Russian cultural practices since 1991; describes main political developments shaping the cultural field in Putin's Russia; and, finally, identifies the Cultural Studies debates the editors of the collection find most productive for investigations of Russia, i.e. the instrumentalization of culture and culture as resource. Relocated in an analysis of a post-socialist society, these conceptualisations seem increasingly problematic in a situation where local and federal policies governing cultural and creative work focus simultaneously on marketization and on nationalism as the main tools of legitimizing the federal government.Peer reviewe

АЛЛОТРАНСПЛАНТАЦИЯ АВО-НЕСОВМЕСТИМЫХ ПОЧЕК У ДЕТЕЙ

At present the problem of donor organs for transplantation shortage remains unsolved. Cautious and mixed attitude towards the transplantation of incompatible kidneys remains, while it could considerably reduce the donor organ waiting time for a recipient. Experience of 19 allotransplantations of ABO-incompatible kidneys in children is analyzed in the article. A group of 14 patients who received ABOcompatible kidneys was chosen for the comparative analysis. Such parameters as the assessment of function of allotransplanted kidneys, morphology character comparison of biopsy materials of allo-kidneys in both groups, actuarial survival rate of the recipients with functioning allografts are used to assess the results. Comparison of the aforementioned parameters showed practically the same results, and that enables us to assert that transplantations of kidneys of ABO-incompatible donors have the right to exist.В настоящее время остается нерешенной проблема нехватки донорских органов для трансплантации. Сохраняется настороженное, неоднозначное отношение к пересадке несовместимых почек, применение которых могло бы значительно сократить время ожидания реципиентом донорского органа. В статье проанализирован опыт 19 аллотрансплантаций АВ0-несовместимых почек у детей. Для сравнительного анализа выбрана группа из 14 больных, которым выполнены пересадки АВ0-совместимых почек. Для оценки результатов использованы такие параметры, как оценка функции аллотрансплантированных почек, сравнение характера морфологии биоптатов аллопочек в обеих группах, оценка актуарной выживаемости реципиентов с функционирующими аллотрансплантатами. Сравнение вышеперечисленных параметров показало практически одинаковые результаты, что дает нам право утверждать: пересадки почек от АВ0-несовместимых доноров имеют право на существование

Trait‐based analysis of subpolar North Atlantic phytoplankton and plastidic ciliate communities using automated flow cytometer

Plankton are an extremely diverse and polyphyletic group, exhibiting a large range in morphological and physiological traits. Here, we apply automated optical techniques, provided by the pulse‐shape recording automated flow cytometer—CytoSense—to investigate trait variability of phytoplankton and plastidic ciliates in Arctic and Atlantic waters of the subpolar North Atlantic. We used the bio‐optical descriptors derived from the CytoSense (light scattering [forward and sideward] and fluorescence [red, yellow/green and orange from chlorophyll a, degraded pigments, and phycobiliproteins, respectively]) and translated them into functional traits to demonstrate ecological trait variability along an environmental gradient. Cell size was the master trait varying in this study, with large photosynthetic microplankton (> 20 μm in cell diameter), including diatoms as single cells and chains, as well as plastidic ciliates found in Arctic waters, while small‐sized phytoplankton groups, such as the picoeukaryotes (< 4 μm) and the cyanobacteria Synechococcus were dominant in Atlantic waters. Morphological traits, such as chain/colony formation and structural complexity (i.e., cellular processes, setae, and internal vacuoles), appear to favor buoyancy in highly illuminated and stratified Arctic waters. In Atlantic waters, small cell size and spherical cell shape, in addition to photo‐physiological traits, such as high internal pigmentation, offer chromatic adaptation for survival in the low nutrient and dynamic mixing waters of the Atlantic Ocean. The use of automated techniques that quantify ecological traits holds exciting new opportunities to unravel linkages between the structure and function of plankton communities and marine ecosystems
