igration and adhesion. Its blood level can correlate with the degree of destructive and reparative processes in the cells of liver and vascular endothelium. Conclusion. A high-fructose diet in rats causes an increase in the studied biochemical parameters of carbohydrate and lipid metabolism, as well as an increase in blood level of the main regulatory protein of the intercellular matrix - fibronectin.Quercetin (Q) is known to be a powerful chelating agent for metal ions. Due to this property, Q, when ingested, is able to intervene actively in microelement homeostasis. The assessment of the possible significance of these effects for the dietary use of Q in obesity is complicated by the fact that in obese patients there are numerous changes in mineral metabolism and microelement homeostasis due to the pathogenesis of the disease. Thus, it is of considerable interest to identify the systemic effects of biologically active substances, including Q, on mineral metabolism in biological in vivo models (due to the limited choice of biosubstrates in clinical observations - blood plasma, urine, hair). The aim was to study the possible effects of Q on the levels of essential, non-essential and toxic elements in mice of three lines db/db with knockout of the leptin receptor gene, prone to spontaneous development of obesity, inbred line C57Bl/6J, relatively resistant to the development of nutritional obesity, and compltween the content of trace elements and biochemical indicators of the intensity of catabolic and anabolic processes. Conclusion. Quercetin has an effect on the homeostasis of microelements, depending both on the animal genotype and on the diet, and not having unambiguous physiological significance. Indicators of the status of essential and toxic trace elements are recommended to be included in the protocols of preclinical trials of the efficacy and safety of minor biologically active food substances.Following a gluten-free diet is recommended by clinical guidelines in the presence of gluten intolerance. buy C-176 However, due to the variety of clinical picture of various forms of intolerance, the elimination of gluten occurs not always timely. There are also diseases that classic treatment regimen does not include diet therapy, however, studies have confirmed the effectiveness of its use. The aim of the research - to study current data on the effectiveness of a gluten-free diet for extra-intestinal manifestations of gluten intolerance. Material and methods. Literature data concerning the effectiveness of including a gluten-free diet in the treatment of various diseases according to the PubMed and eLIBRARY portal were studied. Results. Modern data on the forms of gluten intolerance and their clinical manifestations are presented. The results of both randomized studies and individual clinical cases of gluten intolerance that occurred under the guise of other diseases are presented. A clinical case of an acute onset reproductive system, which were leveled only after the exclusion of gluten from the diet. Conclusion. The presented cases demonstrate a wide variety of clinical forms of gluten intolerance, examples of diagnostic search and dynamics of the clinical picture with the timely appointment of a gluten-free diet are given.The discovery of lactulose as a bifidogenic factor became the background for the appearance of the prebiotics concept. Currently, lactulose is the most studied in terms of medical use oligosaccharide with a high prebiotic index. The exact mechanisms of action of lactulose remain largely unknown despite a number of new researches based on modern methods of molecular biology, genetics, and bioinformatics. The aim of this review to summarize and analyze the actual information about biological activity, probable mechanisms of action, and possible uses of lactulose in human nutrition. Results. The structure of lactulose, methods for its determination and preparation are briefly described. Promising methods for producing lactulose include enzymatic synthesis from lactose using β-galactosidase or epimerase. Information on the physiological effects of lactulose and the mechanisms of its action on the human organism is presented. The works confirming the ability of lactulose to stimulate the growth of bifidobacteria a combination with probiotics, other prebiotics, and as an encapsulating ingredient for vitamins and other functional nutrition ingredients are determined. In this regard, the study of lactulose interaction with the components of complex products is relevant.The episode of acute coronary syndrome is most often preceded by the development of systemic and local inflammation, which plays a significant role in the pathogenesis of the disease. General clinical blood analysis, directly or indirectly reflecting systemic pathological processes in the patient's body based on quantitative and morphological assessment of blood composition, is one of the most affordable methods of laboratory diagnostics in modern public health. Taking into account the growing number of digital data obtained by diagnosticians from analytical systems, there is a growing potential for the use of machine learning methods to increase the effectiveness of provided diagnostic information in the interests of the patient. The aim of this study was to create an algorithm for stratifying the risk of myocardial infarction based on the methods of machine learning in patients with acute coronary syndrome at primary examination. A prospective pilot study was conducted. In total 307 patients with acute coroble and promising for further accumulation of the database with the purpose of additional training of the developed algorithm and improvement of the disease prognosis accuracy characteristics.Currently, the impact of antibiotic resistance on human health is a worldwide problem and its study is of great interest from a molecular genetic, environmental and clinical view-point. This review summarizes the latest data about antibiotic resistance, the classification of microorganisms as sensitive and resistant to the action of antibiotics, reveals the concept of minimum inhibitory concentration from modern positions. The resistance of microorganisms to antibacterial agents can be intrinsic and acquired, as well as being one of the examples of evolution that are currently available for study. Modern methods of whole-genome sequencing and complex databases of nucleotide-tagged libraries give an idea of the multifaceted nature of the mechanisms of intrinsic resistance to antibiotics and are able to provide information on genes encoding metabolic enzymes and proteins that regulate the basic processes of the physiology of bacteria. The article describes the main ways of spreading the resistance of microorganisms, reflects the concepts of "founder effect" and the fitness cost of bacteria, which underlie the emergence and evolution of antibiotic resistance. It is shown that the origin of antibiotic resistance genes that human pathogens currently possess can be traced by studying the surrounding not only clinical, but also non-clinical (ecological) habitats. As well as microorganisms of the surrounding ecosystems are the donors of resistance genes in horizontal gene transfer.There are various diagnostic and research methods for detecting cases of Dengue fever, the effectiveness of which is given in this work. Materials and methods On biomaterial from 70 people, verification of imported cases of Dengue fever into the south of the Far East from 2012 to 2019 is shown. Serological and virological methods were used, as well as PCR. Results Using the immunochromatographic rapid test, the Dengue virus (DENV) NS1 antigen and antibodies to DENV (IgM and IgG) were detected in human blood. We examined 12 patients from the infectious diseases department with unknown fever and the blood of 58 people who applied to clinics in Vladivostok after returning from tourist trips. Dengue fever was diagnosed in 23 patients (32.8%), of which antigen was detected in 56%, IgM antibodies in 91.3% and IgG in 52.1%. In 2 cases (8.7%), only antigen was detected in patients. Three strains of the pathogen were isolated by virological methods from 18 blood samples, two of which turned out to be the DENV of the 1st genotype and one - of the DENV of the 2nd genotype. Using RT-PCR, 38 blood samples were tested positive in the immunochromatographic rapid test, of which in 16 cases (42.1%) a DENV marker was detected, in 11 cases it was genotype 1, in three cases genotype 2, and one each - genotypes 3 and 4. Conclusions 1. The most reliable method of rapid verification (in 100%) the primary infection DENV was the comprehensive determination of antigen and antibodies of the IgM class; 2. With antigenemia, blood should be used to isolate the virus, as well as to diagnose the disease by PCR and to establish the genotype of the DENV; 3. When using only PCR to indicate Dengue virus, a significant proportion of the disease cases will not be diagnosed.When diagnosing bloodstream infection (BI) the culture medium is the basis for growth of microorganisms and obtaining the blood culture. Pancreatic digest from fish meal is the basis of all culture media in Russia. In European countries brain-heart media (BHM) are used for detecting microorganisms in blood. In Russia BHM is not produced. The aim is to work out the formulation and the way of the BHM (broth and agar) preparation in order to improve the efficiency of obtaining blood culture. There were defined the physical and chemical indices and biological parameters of the BHM. The microbiological control of the BHM was carried out by diagnostic study of cardiological patients' blood. On the basis of the developed technique of the brain-heart extraction (BHE) preparation there was created the liquid and agar BHM (LBHM, BHA). The LBHM was poured into bottles which then were filled with the inert gas. The bottles were closed with rubber stoppers and rolled in metal caps became a closed system. Microbiological qan in MPA, (p less then 0,001). Anaerobic microbes did not grow in MPA. When diagnosing bloodstream infection the BHM (liquid and agar) are able to create the optimal conditions for the increase of the wide range pathogen growth.Were studied the genes encoding the virulence factors of 221 strains E. coli O6H1 (194) and E. coli O25H4 (27), isolated in 2014-2018 from stool samples of children and adults examined according to epidemic indications. Molecular methods included PCR with hybridization-fluorescence and electrophoresis detection of amplified products. The strains did not have virulence genes for diarrheagenic E. coli (DEC) pathogroups EPEC, ETEC, EIEC, EHEC, EAggEC, and belonged to the phylogenetic group B2.
