Authors: Stachowiak D , Polanowski A , Bieniarz G , Wilusz T
Published: January 2020

Two serine proteinase inhibitors (ELTI I and ELTI II) have been isolated from mature seeds of Echinocystis lobata by ammonium sulfate fractionation, methanol precipitation, ion exchange chromatography, affinity chromatography on immobilized anhydrotrypsin and HPLC. ELTI I and ELTI II consist of 33 and 29 amino-acid residues, respectively. The primary structures of these inhibitors are as follows: ELTI I KEEQRVCPRILMRCKRDSDCLAQCTCQQSGFCG ELTI II RVCPRILMRCKRDSDCLAQCTCQQSGFCG The inhibitors show sequence similarity with the squash inhibitor family. ELTI I differs from ELTI II only by the presence of the NH2-terminal tetrapeptide Lys-Glu-Glu-Gln. The association constants (Ka) of ELTI I and ELTI II with bovine-trypsin were determined to be 6.6 x 10(10) M-1, and 3.1 x 10(11) M-1, whereas the association constants of these inhibitors with cathepsin G were 1.2 x 10(7) M-1, and 1.1 x 10(7) M-1, respectively.
Alterations in glycosaminoglycans in wounded skin of diabetic rats. A possible role of IGF-I, IGF-binding proteins and proteolytic activity.
Authors: Cechowska-Pasko M , Pałka J , Bańkowski E
Published: January 2020

In the skin of diabetic animal tissues the amount of extracellular matrix (ECM) components is drastically decreased as a result of a reduced rate of their biosynthesis or increased degradation. In the present study we have investigated the mechanism of poor wound healing in diabetic rats. We have found that wounded skin of diabetic rats shows a significant decrease in glycosaminoglycan (GAG) content compared to that of control animals. This decrease was accompanied by significant depletion of insulin-like growth factor-I (IGF-I), known as a stimulator of GAG biosynthesis, and a distinct decrease in the content of high molecular weight IGF-binding proteins (HMW-BPs) with a simultaneous increase in low molecular weight IGF-binding proteins (LMW-BPs) in the sera of diabetic animals. Basing on determination of proteolytic activities we suggest that insulin shortage in diabetes results in increased proteolytic activity in various tissues. Proteolytic enzymes may cleave the HMW-BPs and convert them to LMW-BPs. The LMW-BPs may inactivate IGF-I and eliminate its stimulatory effects on GAG biosynthesis. The proteolytic enzymes may also digest the protein cores of proteoglycans releasing the GAGs and making them more susceptible to the action of glycosidases. These phenomena may be responsible for the observed marked decrease in GAG content in the skin of diabetic rats and disturb the wound-healing process.

Published: January 2020

Human serum contains several glycosaminoglycans (GAGs), mainly chondroitin sulphates and significantly less of heparan sulphate + heparin and dermatan sulphate. The non-insulin-dependent diabetes mellitus (with vascular complications) was associated with a significant increase in total serum GAG concentration, mainly of chondroitin sulphates and dermatan sulphate, with a simultaneous decrease in heparan sulphate + heparin level. These alterations were much more evident in patients with poor metabolic control. Hyaluronic acid (undetectable in healthy subjects and in patients with good metabolic control) appeared only in trace amounts in poorly controlled diabetic individuals. The obtained data allow to conclude that the diabetes mellitus-associated disturbances in tissue GAG metabolism lead to significant alterations in serum GAG composition.

Published: January 2020

O presente trabalho apresenta a análise das referências simbólicas impressas na paisagem urbana da cidade de Campos dos Goytacazes – RJ produzidas por grafiteiros entre os anos de 2004 e 2018. Nessa perspectiva, o graffiti é entendido enquanto uma arte libertária que busca difundir novas ideias, mensagens políticas e referências culturais do lugar. Um movimento artístico que vem passando por processos de ressignificações em sua própria estrutura organizacional, em suas técnicas e estética. Dessa forma, este estudo possibilita um entendimento da criação de uma nova paisagem urbana, onde o sentido da representação é descrito sob a ótica dos artistas, criadores desses novos significados. Os grafiteiros são os sujeitos das ações e as crews constituem-se nos grupos nos quais os sujeitos encontram-se inseridos e podem definir tipos de ações diferenciadas que (re)elaboram cotidianamente a paisagem urbana. A paisagem, portanto, é produto e produtora de ações realizadas por agentes culturais/políticos.Palavras-chave: Graffiti. Ação. Paisagem. Política Cultural.

Anopheles gambiae sensu lato is the most important malaria vector in Nigeria. Referral hospitals have a mandate to provide patients with the best health care. The persistent complaints of the nuisance caused to patients, professionals, and visitors by mosquitoes at the University of Port Harcourt Teaching Hospital (UPTH), a referral Hospital, prompted the design of this study to assess the species composition, density, and man-biting rates of endophilic mosquitoes at the UPTH. A longitudinal entomological survey covered dry and wet seasons, February–July 2017, with sampling done thrice weekly, using the aspiration method. Caught mosquitoes were identified by standard keys using a dissecting microscope and classified according to their gonotrophic status. A total of 1,307 mosquitoes in two genera (Culex, Anopheles) and three species (Culex quinguefasciatus, Anopheles gambiae s.l. and Anopheles mouchetti) were caught, comprising 150 (11.5%) males and 1,157 females. The most abundant species was Culex quinguefasciatus (98.01%), An. gambiae s.l. (1.64%), and the least abundant, An. mouchetti (0.35%). Gonotrophic examinations of caught females revealed 52.8% blood-fed and 40.1% unfed. Culex quinquefasciatus had higher man-biting rates (1.26 bites/patient/night) than Anopheles (0.2 bites/patient/night). The Accident and Emergency ward, 595 (45.5%), and the Obstetrics and Gynecology ward, 328 (25.1%), had the highest records of caught mosquitoes among the four wards visited for collections. No significant difference (Fcal = 1.0722, Ftab = 13, p > 0.05, df = 2) existed between wet and dry seasons' collections. Because of the high numbers of blood-fed Anopheles, an urgent need for intervention is required to reduce the case of vector/human contacts; notably, larval source management will be a principal approach toward control.

Authors: Widyaswari Meidyta Sinantryana , Noventi Iis , Supriyana Herdiantri
Published: January 2020

Introduction: Black cumin (Nigella sativa) is widely used to treat various diseases. It is also believed to relief skin conditions accompanied by itching symptom, such as atopic dermatitis (AD) or eczema. However, the anti-eczema mechanism of action is still unclear. The aims of this syudy was to  identify anti-eczema mechanism of action of N. sativa for AD using computer aided prediction and pathway analysis based on protein-chemical networks. Methods: We utilized dataset consisting chemical compounds of N. sativa from KNApSAcK. It is a comprehensive species-metabolite relationship database. Using canonical SMILES strings that encode molecular structures of each compound, we predicted the probabilities of activity (Pa) for anti-eczema effect based on PASS algorithms. The compounds with Pa >0.7 were included for pathway analysis based on protein-chemical interaction networks in STITCH database. We selected interactomes built by experimental data, gene co-expression, closest gene position, fusion, co-occurence, computational prediction, and other secondary data. Results: Thirty-five active compounds of N. sativa have been utilized and 19 of them have potential anti-eczema effects. Oleic acid and lauric acid were predicted with Pa-value of 0.947 and 0.920 for anti-eczema effect, respectively. However, only lauric acid was confirmed having a plausible mechanism of action via LY96-TLR4- PIK3R1 pathway for lipopolysaccharide receptor activity (false discovery rate [FDR] = 0.0243) and low-density lipoprotein particle receptor binding (FDR = 0.0118). Conclusion: Lauric acid in N. sativa has potential antieczema effect to prevent relaps in AD patients by controlling opportunistic bacterial infection that aggravates itching symptom in this condition.

Published: January 2020

Introduction: Pain causes deterioration of quality of life. Nonsteroidal anti-inflammatory drug (NSAID) is used to relieve pain with upper gastrointestinal side effects. Zingiber cassumunar Roxb. (known as bangle) is commonly used to relieve pain, but no study has been proved to have analgesic effect. In empirical study, bangle is a potential analgesic due to its bioactive compound named zerumbone. The aim of this study was to investigate the analgesic effect of bangle rhizome ethanol extraction on thermally induced pain.Methods: Five groups of male Mus musculus consisting of 6 mice each were used. A single dose of bangle extract 2 mg/20 g, 4 mg/20 g, 8 mg/20 g, aspirin 1.82 mg/20 g, and aquadest 0.2 ml were administrated. The analgesic effect was evaluated by hot plate test. The test was evaluated at 15th, 30th, 45th minute. Latency period was observed when mice showed pain responses including hind paw shaking, hind paw licking or jumping. The data was analyzed by paired T-test and one-way ANOVA.Results: Results showed that all doses of bangle extract and aspirin 1.82 mg/20 g produced significant latency period (p<0.05) compared to baseline in each group using paired T-test. Latency period of bangle extract 8 mg/20 g was more significant than bangle extract 2 mg/20 g and 4 mg/20 g. One-way ANOVA showed no significant difference in latency period (p=0.1) between bangle extract and aspirin (p>0.05).Conclusion: Bangle extract has analgesic effect on thermally induced pain. The minimum dose for analgesic is 2 mg/20 g or potentially less.

In sugar technology, the degree of sucrose extraction from sugar beet is largely determined by the state of the food system of diffusion juice formed during the extraction of sucrose from beet chips. Potential states of the food system of diffusion juice obtained from healthy and infected sugar beet under the condition of optimal technological regime and technological aids used are shown. It is noted that the food system of the diffusion juice from the infected with mucous bacteriosis sugar beets shows a tendency to instability due to the accumulation in it of hard removable polysaccharide high-molecular compounds - dextran,Levan ,effective way to remove which are enzyme preparations of glycosidase action (dextranase and Lebanese). The state of the food system of the diffusion juice from sugar beets with the extent of mucous bacteriosis lesions of 5 and 10% is studied, based on the modeling of technological processes of sucrose extraction and lime-carbon dioxide purification of diffusion juice by means of diagnosing representative indicators. As used auxiliary substances used complex enzyme-antiseptirujut drug Extrasept 2, containing dextranase and Levanzo; antifoam Laprol PS-1; antimicrobial agent Navisan M1. It is identified that the introduction of the specified enzyme preparations into the food system of the diffusion juice promotes its transfer into stable state with the best values of the parameters: the content of high molecular compounds were lower by 42–44%; the purity was higher by 2,5–2,6%; dynamic viscosity by 10–15% lower as compared to the variants without application of enzyme preparations. This is due to the hydrolyzing effect of enzyme preparations, confirmed by the results of the microscopy of cellular and diffusion juices. Stable state of the food system of diffusion juice contributed to the improvement of the quality indicators of the purified juices.

Published: January 2020

Under conditions of increasing of industrial consumption of sugar in Russia and applying specific requirements for sugar as primary commodity, issues of flexibility and readjustment of process lines for production of sugar of prescribed properties become relevant. Maintaining the quality and safety of products in this case can be ensured by the transition of the process control system to a new paradigm, including the improvement of tools in the form of measurement methods. As a basis for the methodology of forming the system of control methods, three principles have been proposed: the package principle, the acquisition of standard and extended case methods, and the unification of methods presentation. The package principle as a tool of the rule-making methodology, with its detailed elaboration in standardization, has been considered in detail. It is shown that in order to ensure the compatibility of operational control methods, it makes sense to provide unified approaches to their development, essential content, construction and presentation, which is possible by adopting the package principle used in standardization. The necessity of expanding the nomenclature of control parameters of the technological flow of sugar production was considered in detail; the existing prerequisites were shown. It was proposed to provide the implementation of nomenclature variations of control parameters on the basis of the formation of two case methods, differentiated according to the destination of the sugar produced - for population or industrial consumers. It is noted that control parameters of the technological flow of sugar production are the quantities related to the subject of quantitative chemical analysis, the practical side of which is reflected by analytical methods. Due to the current variety of attributes of methods presentation, their harmonization is required both by means of the unification of the presentation of measurement methods of the same parameters for different control objects according to their substantive essence, and by means of the unification of the text presentation of the methodology. The principles considered together constitute the essence of the methodological approach to the formation of the system of control methods of the technological sugar production flow.

Published: January 2020

Over the past 30 years, alarming growth in alcohol consumption has been observed in many countries around the world, which is reflected in an increase in alcohol production. For example, in China, beer production has increased 2.27 times over the past "*"18 years. The annual per capita consumption of alcoholic beverages in China increased from 4.9 liters in 2003–2005 to 7.2 liters in 2016. In Europe, various chemicals are used to treat alcohol dependence. Eastern medicine for the treatment of alcoholism uses extracts of the plant Pueraria Lobata Flower (kudzu). The principle of action of kudzu is based on a decrease in the activity of enzymes that break down ethanol in the human body, as a result of which the metabolism of ethanol in the liver is optimized. At the same time, the toxic effects of alcohol are reduced. With a decrease in toxicity while enhancing the effect of intoxication, the need for alcohol decreases. The purpose of these studies was to study the effect of the extract from kudzu flowers on reducing the toxicity of ethanol and to identify the possibility of using the extract in brewing. Determination of the concentration of alcohol, at which there is a decrease in its toxicity with the addition of the extract, was carried out using a test with Saccharomyces cerevisiae yeast. In the course of studies, a positive effect of the extract from kudzu flowers on the resistance of yeast to ethanol stress and, as a consequence, on their physiological activity was established. In addition, it was concluded that it is advisable to add the extract from kudzu flowers to beer after the filtration process.

The effectiveness of the probiotic complex A2 using to increase the productivity and quality of rabbit meat was studied by us. The studies were carried out in LLC "Lipetsk rabbit' on a hybrid livestock "Hypharm" of French selection at the age of 45 days. The experimental population was divided into control and experimental groups by the method of pair-analogues. The rabbits of the control group received PZK-92 compound feed, the livestock of the experimental groups was fed with PZK-92 compound feed with the introduction of the A2 probiotic complex in dosages of 0.6 and 1.0 g / kg of compound feed. When applying the optimal dosage of the used probiotic complex, which amounted to 0.6 g / kg of feed, 100% livestock safety is achieved, slaughter yield is increased by 4.51% with a decrease in feed costs by 1.42 ECE, as well as a positive effect on nutritional and biological value of rabbit meat was observed. An increase in profit by 3616.0 and profitability (up to 35%) by 12% in relation to the control group (23%) was achieved. This creates the prerequisites for the widespread use of this feed additive in the industrial complexes of the rabbit industry.
Presentation of three dimensional geometric characteristics of food porous systems in the form of statistical functions
Authors: Zhukov V. G. , Lukin N. D. , Chesnokov V. M.
Published: January 2020

The article discusses the method of representing the three dimensionless geometric characteristics of porous materials in the form of statistical functions. The technique allows to obtain formulas for histograms of porous materials. The study relates to the analytical development of a method for determining the dimensionless parameters of food porous media. As an example, we consider a porous material similar in geometrical characteristics to a typical food product with a homogeneous and isotropic porous medium similar to starch, finely divided food additives, and flour. The study is based on the statistical lognormal distribution of random variables and the analytical relationship between the three dimensionless integral parameters of porous systems. The formulas of three dimensionless geometric parameters of a porous medium are obtained analytically: discontinuity, transparency, and porosity. They take into account the statistics of random pore size distribution. The formulas include an experimental integral parameter of porosity, defined by standard techniques. It corrects the results of the automated determination of the pore size distribution. The formulas allow calculating the influence of individual size groups of pores or of their entire size ensemble, which is important in calculating heat and mass transfer processes in porous food, chemical and other technologies. The considered technique allows to apply it in similar studies for statistical tasks of various types.

Published: January 2020

By the method of selecting components, promising compositions were identified for enriching traditional recipes for vegetable casseroles. Eggplant, zucchini, apples and pumpkin were chosen as promising components. To use vegetable raw materials in the production of casseroles, the chemical composition and nutritional value of promising raw materials were studied, the cost of developed products was determined. As a protein fortifier used a mixture of protein composite dry. As a result of research, a characteristic of microbiological, organoleptic indicators and nutritional value of vegetable casseroles was obtained. It was established that the nutritional and energy value of all developed samples in terms of the content of basic food substances has higher values: proteins – by 169.9–295.22%; fats – by 85.4–218%; carbohydrates – by 13.57–26.68% compared with traditional casseroles. The cost of produced vegetable casseroles is directly proportional to the concentration of dry protein composite mixture. The losses during the heat treatment of enriched vegetable casseroles are studied. It was found that casseroles have large mass losses compared to control samples. This is due to the fact that up to 50% of juicy vegetable raw materials (pumpkin, squash) are added to the recipes of enriched casseroles. In assessing the quality of new products used qualitative and quantitative methods. Organoleptic quality assessment of the developed casseroles was carried out on a 10 point scale. It was established that all presented samples of enriched casseroles: cabbage, potato, carrot and vegetable had high organoleptic characteristics. Casseroles with the addition of 2-3 types of vegetables possessed the best organoleptic properties. Microbiological indicators of casseroles (semi-finished product of high degree of readiness) comply with the requirements of SanPiN 2.3.2.1078-01, index 1.9.15.14. The cost of produced vegetable casseroles depends on the price of the dry protein composite mixture. Protein-rich vegetable casseroles are recommended in rational and dietary diets with protein deficiency and are included in the diets of standard diets - low-protein and low-calorie.

The study was aimed at developing a technology for preparing various semi-finished products from pork meat using low-temperature processing "Su-Vid". The main physicochemical indicators, functional-technological and structural-mechanical characteristics of semi-finished products, the chemical composition of semi-finished products and finished products were identified and determined experimentally, and organoleptic analysis was carried out. The data indicate that the use of low-temperature processing significantly affects the characteristics of manufactured products, which improves its performance. In particular, pork semi-finished products prepared at low temperatures are characterized by the yield: steak – 93.9%, ribs – 92.6%, in comparison with the control regime, 7.5 and 6.2% higher. The complex of data obtained showed that the samples of semi-finished pork, according to the experimental regimes of heat treatment, in terms of safety, fully meet the requirements of TR TS 034/2013. Analysis of semi-finished pork products showed that products prepared using the Su-Vid technology had high organoleptic characteristics, taste and sensory characteristics. During the storage of semi-finished products, minor changes in proteins and fats, as well as organoleptic, sanitary and microbiological characteristics, took place. As a result, a bone steak was developed in the Caucasian marinade and pork ribs in the Monte Ritz marinade made using the Su-Vid technology. The results allow us to judge that this technology is quite promising and has a positive effect on the characteristics of manufactured products. The widespread introduction of this technology in the meat industry will allow the development of semi-finished products and products of high quality, nutritional and biological value compared to products manufactured by traditional methods, as well as reduce production costs.

Transition metals are complexing substances, that is why being incorporated into the sensor modifiers, they can improve detection discrimination. The method of piezoelectric microweighting was used to study the sorption characteristics of the films based on partially soluble phosphates of 3d-elements (manganese (II), iron (II and III), nickel, copper, zinc, chromium) and coatings bearing partially soluble ferrous salts (hydrated oxide, fluoride, carbonate, sulfide, phosphate). The salts were created immediately prior to analysis, with bee glue as a filming agent. The method of immersion sensors in suspension of the filming agent and partially soluble salt, that was kept homogeneous by ultrasonic bath, was recognized the best way of film formation. Sorption characteristics of the composed coatings of piezoelectric resonator were estimated by the area under sorption kinetic curve and by peak value of sensor oscillation frequency drop during analysis of equilibrium gaseous form received over pure substances (water, phenol, isopropanol, isobutanol, acetous acid, chloroform, benzene, toluene, acetone, ethyl acetate, ammonia, diethyl amine, triethylamine, tert-butylamine, benzylamine). It was possible to determine the identifying variables Aij, minimax values of those allow to detect individual substances in the mixed vapour. Modifier application of piezoelectric resonators of phosphates of different 3d-elements is more efficient than use of different salts of one element. The shortcoming of the proposed modifiers is temporarily stable amine (ammonia) complexation. Those analytes desorption from the films proceeds slowly, it is determined by the bond strength of complexes and takes from 2 to 6 hours. However, array of seven sensors, modified by phosphates of transition metals of group IV, allows to detect oxygen- and nitrogen-based compounds vapours in the mixed vapour as well as to detect ammonia, diethyl amine and triethylamine individually.)
Scientific research on the improvement of commercial banks and application of innovations

It should be borne in mind that the global changes taking place in the world have led to significant innovation changes in financial institutions, one of the main mechanisms in the information economy, and have had a significant impact on the rapid development of the banking sector and the specialization of modern requirements. Proper regulation of market relations has always been a private and public sector. In particular, the study of the globalization processes and the problems that arise as a result of the activities carried out in the banking sector are on the agenda. The elimination of problems in the banking sector and further development and improvement of the service sector will always remain relevant. The new requirements for economic conditions to adapt to the requirements of the modern era come in parallel, respectively. To apply new banking products, strategy and policy based on the bank's marketing service information and materials should be prepared. Bank's strategy and policy should be formulated specifically in the plan for preparation, supply and sale of banking products. Each bank should make decisions on modification of the banking product based on marketing research and develop a long-term business plan for the introduction of new banking services. High level of production relations dynamics, special attention to the formation of commodity-market relations, necessitates the development of a clear tactic and strategy for modern monetary and credit policy and banking business management. Modern analysis and monitoring indicate that the institutional economic problems arising from monetary policy can be resolved either through the level of credit investments, concentration of bank capital, the average interest rate on loans and deposits, the ability to attract resources or many other factors. In the context of new economic relations, modeling based on mathematical statistical methods, and expert opinions should be used in the development of the scenario of banks behavior.
Trends and prospects for the development of the livestock industry of the meat and food subcomplex in terms of resource saving and public administration

The livestock industry is an important structural element of the effective functioning of the meat subcomplex and the whole agroindustrial complex as a whole. In this sphere of management, about half of the gross agricultural output is produced (in 2017 – 48.7%). Held reform, transformation of agricultural sector in the 90-ies of XX century had a significant impact on the course and direction of this industry segment (violation of the integrity and structure of the gap and the loss of intra - and inter-industry linkages, illegal privatization, as a consequence, the recession and the bankruptcy of many companies). This situation has been stabilized and the industry has acquired a positive trend of development recently (6–7 years) after the adoption and implementation of targeted programs in the field of agriculture and food market. At the moment, modern domestic animal husbandry is developing at a fairly steady pace, but there are also systemic problems: price disparity; low resource efficiency; high depreciation of production assets and means of circulation; shortage of free cash and low availability for large credit loans; lack of highly qualified specialists; lack of implementation of mechanization and automation systems; feed supply problems. It is worth noting that this range of problems is not widespread, but they occur in many livestock farms. All this requires modern production management and public administration to take effective measures to modernize industrial enterprises. In this context, the state should create optimal conditions for fruitful interaction between investors and potential customers, act as a moderator, guarantor and insurer of the fulfillment of all obligations and agreements. It is also required to subsidize the reimbursement of costs for technical and technological re-equipment of the industry from the Federal (20–35%) and regional (20-25%) budgets; to create effective sales channels; to support projects in the field of breeding and breeding work; to continue to pay subsidies to compensate for part of the cost of increasing the number of livestock; to justify a clear action plan aimed at implementing projects in the field of modernization and reconstruction of the sectoral sphere of meat livestock for the period up to 2025; to develop a system of measures and to intensify the process of creating livestock industry associations in the regions on the basis of integration and cooperation approaches.
