    Here we describe Cryptogamic Russian Information System (CRIS), a web service cataloguing the biodiversity of cryptogams: cyanobacteria, fungi (including lichens), and bryophytes. CRIS incorporates a wide spectrum of data types, allowing for greater ease of use. It is possible to print the labels for herbarium collections, to input literature references, media files, etc., using CRIS which has a flexible interface and specific technical abilities. Currently, CRIS contains ~ 90,000 herbarium records, including 67,861 records of bryophytes, 12,486 records of lichens and 3,800 records of cyanobacteria. Data analysis of the different taxonomic groups is provided below. Perspectives and directions for the future development of CRIS are discussed

    Antioxidant and Cytotoxic Activities of Kudzu Roots and Soy Molasses Against Pediatric Tumors and Phytochemical Analysis of Isoflavones Using HPLC-DAD-ESI-HRMS

    Pediatric solid tumors (PSTs) are life-threatening and can lead to high morbidity and mortality rates in children. Developing novel remedies to treat these tumors, such as glioblastoma multiforme and sarcomas, such as osteosarcoma, and rhabdomyosarcoma, is challenging, despite immense attempts with chemotherapeutic or radiotherapeutic interventions. Soy (Glycine max) and kudzu roots (KR) (Pueraria spp.) are well-known phytoestrogenic botanical sources that contain high amounts of naturally occurring isoflavones. In the present study, we investigated the antioxidant and cytotoxic effects of the extracts of KR and soy molasses (SM) against PSTs. The green extraction of isoflavones from KR and SM was performed using natural deep eutectic solvents. The extracts were subsequently analyzed by high-performance liquid chromatography (HPLC)-diode array detector (DAD) coupled with high-resolution (HR) mass spectrometry (MS), which identified 10 isoflavones in KR extracts and 3 isoflavones in the SM extracts. Antioxidant and cytotoxic activities of KR and SM extracts were assessed against glioblastoma multiforme (A-172), osteosarcoma (HOS), and rhabdomyosarcoma (Rd) cancer cell lines. The KR and SM extracts showed satisfactory cytotoxic effects (IC50) against the cancer cell lines tested, particularly against Rd cancer cell lines, in a dose-dependent manner. Antioxidant activity was found to be significantly (p ≤ 0.05) higher in KR than in SM, which was consistent with the results of the cytotoxic activity observed with KR and SM extracts against glioblastoma and osteosarcoma cells. The total flavonoid content and antioxidant activities of the extracts were remarkably attributed to the isoflavone content in the KR and SM extracts. This study provides experimental evidence that HPLC-ESI-HRMS is a suitable analytical approach to identify isoflavones that exhibit potent antioxidant and anticancer potential against tumor cells, and that KR and SM, containing many isoflavones, can be a potential alternative for health care in the food and pharmaceutical industries. © 2022 by the authors.

    MORPHOFUNCTIONAL PECULIARITIES OF MUCOSAL IMMUNITY DEPENDING ON METHODS OF OPPORTUNISTIC MICROBIAL INTRODUCTION

    Immunophenotypic and morphological peculiarities of immune reactions under intranasal, peroral and subcutaneous introduction of multicomponent vaccine Immunovac VP-4 containing a group of opportunistic bacterial antigens were investigated. The investigated preparation was found to cause marked activation of congenital immunity effectors both in parenteral and mucosal immunization. It is manifested in the expression of differential, costimulatory, adhesive molecules on the surface of mononuclear leukocytes in proliferation of key mucosal immunity effectors (γδТ, В1, NK cells), and changes in structure, cellular composition of immunocompetent organs both regional and distant as to the site of introduction. Currently existing data on effects and mechanisms of vaccine and immunomodulator mucosal introduction allows considering the development of mucosal mono- and associated vaccines as the priority direction in modern vaccinology

    The methodical, technical and software realization of the biofeedback of expiration parameters are described. The biofeedback training method based on the breath frequency and CO2  concentration regulation is proposed. Preliminary study was conducted in the group of patients after abdominal surgical. It has been shown that the patients master their skills of CO2  concentration self-regulation. Using biofeedback for the postsurgical rehabilitation facilitates the rapid recovery of the expiration parameters.В статье рассматриваются методические, технические и программные аспекты адаптивного биоуправления, организованного по параметрам внешнего дыхания. Предложена методика БОС-тренинга, основанная на регуляции частоты дыхания и содержания углекислого газа в выдыхаемом воздухе. Проведены предварительные исследования в группе пациентов после абдоминальной хирургической операции. Показано, что пациенты осваивают навыки произвольной регуляции содержания углекислого газа в выдыхаемом воздухе. Был сделал вывод о том, что применение БОС-тренинга в послеоперационном периоде способствует быстрому восстановлению параметров внешнего дыхания

    Today, cancer is one of the most widespread and dangerous human diseases with a high mortality rate. Nevertheless, the search and application of new low-toxic and effective drugs, combined with the timely diagnosis of diseases, makes it possible to cure most types of tumors at an early stage. In this work, the range of new polysubstituted 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines was extended. The structure of all the obtained compounds was confirmed by the data of 1H, 13C NMR spectroscopy, IR spectroscopy, and elemental analysis. These compounds were evaluated against human recombinant CK2 using the ADP-GloTM assay. In addition, the IC50 parameters were calculated based on the results of the MTT test against glioblastoma (A-172), embryonic rhabdomyosarcoma (Rd), osteosarcoma (Hos), and human embryonic kidney (Hek-293) cells. Compounds 5f, 5h, and 5k showed a CK2 inhibitory activity close to the reference molecule (staurosporine). The most potential compound in the MTT test was 5m with an IC50 from 13 to 27 µM. Thus, our results demonstrate that 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines are promising for further investigation of their antitumor properties. © 2022 by the authors.Ministry of Education and Science of the Russian Federation, Minobrnauka: FEUZ-2020–0058, H687.42B.223/20This work was financially supported by the Ministry of Science and Higher Education of the Russian Federation, State Contract № FEUZ-2020–0058 (H687.42B.223/20)
