The article describes our experience in developing and training an artificial neural network based on artificial intelligence algorithms for recognizing the characteristic features of benign laryngeal tumors and variants of the norm of the larynx based on the analysis of laryngoscopy pictures obtained during the examination of patients. During the preparation of data for training the neural network, a dataset was collected, labeled and loaded, consisting of 1471 images of the larynx in digital formats (jpg, bmp). Next, the neural network was trained and tested in order to recognize images of the norm and neoplasms of the larynx.

Lately, in case of a number of life-threatening and chronic progressive rare (orphan) diseases, resulting in decreasing of life expectancy of citizens or their disability, the powers to support patients with medications were transferred from regional to federal level. Among these diseases are hemolytic uremic syndrome, mucopolysaccharidose type I, II, VI, juvenile arthritis with systemic onset, unspecified aplastic anemia, hereditary deficiency of factors II (fibrinogen), VII (labile), X (Stuart-Prauer). The article considers data concerning hemolytic uremic syndrome, mucopolysaccharidosis type I, II, VI, juvenile arthritis with systemic onset - the diseases for which medication support provision was transferred to Federal level in the first place and for which at the time of preparation of the article there were sufficient data to analyze.

Expression of the protein E gene resulted in the BGs that retained the shape of the original bacterium. Co-expression of this gene with genes coding for holin-endolysin system of the phage L-413C caused formation of structures resembling collapsed sacs.

The study was carried out to analyze detection of rare diseases that are not included into listings of rare (orphan) diseases to be treated at the expense of budget resources of the Russian Federation Russian Federation (hereinafter referred as rare diseases out of reimbursement). The analysis of detection of patients with rare diseases out of reimbursement in Russian Federation was carried out. The information was collected and summarized on the basis of open sources by the way of formalized personal request to the heads of patient and public organizations providing care of patients with rare diseases out of reimbursement.

The aim of this study was to assess the association of polymorphic genetic variants APOA5 (S19W/rs3135506), CETP (Taq1B/rs708272), PON1 (Q192R /rs662) and PPARG (Pro12Ala /rs1801282) with T2DM and macrovascular complications in patients with T2DM resident in Northwestern Russia. We examined 386 patients with T2DM and 199 healthy controls.

Accumulation of this polymer occurs in the cells grown either anaerobically on the light or aerobically in the dark. On the medium with C/N imbalance (C/N = 4), PHB content during the stationary growth phase under aerobic conditions in the dark was 40 and 70% of the dry biomass of the R and M variant, respectively.

Under all cultivation conditions tested, bacteriochlorophyll a content was 2-3 times lower in the cells of the M. variant compared to the R variant, which therefore was predominant in the cultures grown in the light.

Modern FAPs belonging to the order Chloroflexales are divided into two suborders: Chloroflexineae and Roseiflexineae. Representatives of Roseiflexineae lack chlorosomes and synthesize bacteriochlorophyll a, whereas those of Chloroflexineae synthesize bacteriochlorophylls a and c and utilize chlorosomes for light harvesting.

Nonsulfur purple bacteria Rhodobacter sphaeroides, Rhodobaca bogoriensis, and aerobic anoxygenic phototrophic bacteria Roseinatronobacter thiooxidans were the subjects of investigation. All these organisms were able to grow under aerobic conditions in the dark using the respiratory system with cytochrome aa3 as the terminal oxidase.

CO2 can be both exogenous and secreted by another growing yeast culture. We also show that this effect can be observed only in the lag-period, and demonstrate minimal doses and duration of culture exposition to CO2.

It is found that the growth of this bacterium in batch and continuous cultures and the assimilation of acetate in cell suspensions are not stimulated by bicarbonate. The consumption of acetate is accompanied by the excretion of glyoxylate and pyruvate into the medium, stimulated by glyoxylate and pyruvate, and inhibited by citramalate.
