Phytochemical Characteristics and Antimicrobial Effects of Nonea rossica (Boraginaceae) Extracts.

Phytochemical characteristics and antimicrobial properties of extracts were studied in Nonea rossica Steven (Boraginaceae), which is widespread in Russia. The aerial part (herb) of N. rossica was harvested from a steppe meadow in the Novosibirsk region during flowering.

[The impact of digital technologies on labor organization in health care scope].

Enhancement of the health care system in Russia continues to be one of key directions of National development. In conditions of deficiency of personnel, systemic changes are needed to transit to qualitatively new level. The application of digital platforms permits to resolve a number of issues related to accessibility and quality of medical services.

Decellularization of Human Pancreatic Fragments with Pronounced Signs of Structural Changes.

A significant lack of donor organs restricts the opportunity to obtain tissue-specific scaffolds for tissue-engineering technologies. One of the acceptable solutions is the development of decellularization protocols for a human donor pancreas unsuitable for transplantation. A protocol of obtaining a biocompatible tissue-specific scaffold from decellularized fragments with pronounced human pancreas lipomatosis signs with preserved basic fibrillary proteins of a pancreatic tissue extracellular matrix was developed.

The state of the art in beyond 5G distributed massive multiple-input multiple-output communication system solutions.

Beyond fifth generation (5G) communication systems aim towards data rates in the tera bits per second range, with improved and flexible coverage options, introducing many new technological challenges in the fields of network architecture, signal pro- cessing, and radio frequency front-ends. One option is to move towards cell-free, or distributed massive Multiple-Input Multiple-Output (MIMO) network architectures and highly integrated front-end solutions. This paper presents an outlook on be- yond 5G distributed massive MIMO communication systems, the signal processing, characterisation and simulation challenges, and an overview of the state of the art in millimetre wave antennas and electronics.

[The efficiency of combined methods of lithotripsy for ureteral stones].

Extracorporeal shockwave lithotripsy (ESWL) is the first line treatment of uncomplicated upper ureteral stones. Ureterorenoscopy with contact lithotripsy (URS) are useful for middle and lower ureteral stones. However, the presence of residual calculi, the stone fragments migration and the formation of "steinstrasse", when using those methods separately, prompts employing combination of lithotripsy modalities.

A Spinal Cord Stimulation Service Review From a Single Centre Using a Single Manufacturer Over a 7.5 Year Follow-Up Period.

Background: Spinal cord stimulation (SCS) is a recognized management option for patients with refractory neuropathic pain. Despite randomized controlled trials reporting the effectiveness of SCS, there is a lack of long-term data reflecting usual SCS practice. The aim of this study is to present the long-term outcomes of a cohort of patients from a single centre undertaking SCS with devices from a single manufacturer.

[Erythropoiesis and functional characteristics in bone marrow erythroblastic islets during stimulated adn inhibited erythropoiesis].

When erythropiesis is stimulated (acute blood loss) or inhibited (posttransfusion polycythemia), there are early changes in the cytochemical values of erythroblastic islets (EI): in the levels of acid and neutral glucoconjugates and in the activity of nonspecific esterase. A close correlation has been found between the erythropoiesis in EI and its functional characteristics. It is concluded that central macrophages play the key role in the modulation of EI erythropoiesis.

[The mechanisms of cellular complementarity in the erythroblast islands of the bone marrow].

Phenylhydrazine was shown to reduce the content of erythroblast islands (EI) within 24 hrs in the rat bone marrow, the effect depending on the dose. Simultaneous strengthening of phagocytic activity, acidifying of lysosomes central macrophages EI and lowering of electrophoretic mobility, were observed. The proteinase inhibitor contrycal (50 and 500 i.
