INFLUENCE OF NANOSIZED SILICA OXIDE SUSPENSION ON NITRIC OXIDE PRODUCTION IN RATS TESTES DURING CHRONIC NITRATE-FLUORIDE INTOXICATION
Authors: Akimov O.Ye. , Solovyova N.V. , Kostenko V.O.
Published: April 2020

In the Poltava region of Ukraine there is a high possibility of combined excessive intake of nitrates and fluorides, since the waters of the Buchaksʹkii aquifer are rich in fluorine ions, moreover, the Poltava region is a region with a developed agriculture.

The purpose of this work is to determine the effect of nanosized silicon oxide suspension on the changes in the activity of nitric oxide cycle components, components, and, namely the total activity of NO-synthases (NOS), the activity of constitutive forms of NOS (cNOS), inducible form of NOS (iNOS), nitrate reductase, nitrite reductase, nitrite reductase, nitrite reductase in the testes of rats under the conditions of chronic combined nitrate-fluorodide intoxication.

Materials and methods. The study was conducted on 15 mature male Wistar rats weighing 200-253 g. The animals were randomly divided into 3 groups of 5 animals in each. The first group received daily saline solution through a gastric tube. The second group (chronic combined intoxication group) received sodium nitrate and fluoride in a dosage of 500 mg / kg of sodium nitrate and 10 mg / kg of sodium fluoride. The third group against the background of chronic combined intoxication modelling additionally received a suspension of nanosized silicon oxide is a dosage of 100 mg / kg of active substance.

Results. Chronic combined intoxication increases total NOS activity by 65.9% compared to the control group. The increase in NO production by NOS is the result of a 4-fold increase in iNOS activity, since the activity of cNOS under these conditions does not change significantly. Nitrite reductase-dependent NO production increases by 66.7%, nitrate reductase activity increases by 77.8%. Nitrite content in the testes homogenate grows in 2.17 times. Hydrolytic cleavage of L-arginine by arginase increases in 2.88 times. The introduction of nanosized silicon oxide suspension under the conditions of chronic combined intoxication did not statistically significantly change the total NOS activity and cNOS activity compared to the group exposed to chronic intoxication. However, iNOS activity reduces in 3.69 times. Nitrate reductase activity decreases in 1.6 times, while nitrite reductase activity decreases in 45%. The activity of arginases lowered in 2.38 times. The nitrite content of the testes cut down by 23.6%.

Conclusions. Chronic combined nitrate-fluoride intoxication leads to the development of hyperproduction of nitric oxide in the testes of rats by activating the inducible isoform of NO synthase and nitrite reductases. The use of nanosized silica suspension during chronic combined intoxication is an effective method to correct nitric oxide overproduction in the testes of rats.
MORPHOFUNCTIONAL STATE OF THE STOMACH AND CAECUM IN WHITE RATS AFTER THE COURSE OF CLARITHROMYCIN
Authors: Hryn V. H.
Published: April 2020

Introduction. The pathogenesis of dysbacterioses associated with antibiotic therapy is an urgent medical problem, although some other exogenous and endogenous factors may contribute to the microbiocenosis distortion in the host organism. Purpose. The paper was aimed at studying the morphofunctional state of the stomach and caecum of albino rats after the course of clarithromycin. Material and methods. 30 mature albino male rats weighting 200,0±20,0 g were involved into the experiment. Antibiotic was given to the rodents as a food supplement during their two-meals-a-day feeding. Portions of the stomach and caecum have been studied. Serial paraffin sections were analyzed by using the “Konus” light microscope. Morphometric characteristics of the tissue structures were obtained by the Sigeta X 1 mm/100 Div.x0.01mm stage micrometer. Results and conclusions. In 12 out of 30 subjects, the comparative volume of the caecum was almost twice as less than the volume of the stomach due to a significant enlargement of its fundus, caused by isometric flattening and convergence between its mucous membrane and muscular tunic. In 18 experimental animals, the volumetric capacity of the caecum was twice as larger than the stomach. In contrast, a decrease in the volume of the cecum is associated with a thickening of its wall and increased formation of folds of the mucous membrane that is, probably, caused by insufficient entering of metabolic by-products from the small intestine.

Authors: Nazarenko S. M.
Published: April 2020

The main purpose of educational work is to provide high-quality training of medical professional able to make adequate decisions in both standard and atypical situations in their clinical practice. The theoretical foundation of students’ clinical thinking is being fostering through the course of pathophysiology, and interdisciplinary approach plays an essential role in teaching this course. The purpose of this work is to justify the necessity for interdisciplinary approach through delivering the material on typical pathological processes on the example of pain in order to improve the quality of teaching pathophysiology. Pain is a leading symptom for the most diseases. At the same time, pain can significantly affect the course of somatic pathology. Therefore, the doctors must have basic knowledge of pathophysiology of pain and be able to apply treatment methods to consistent first-line therapy. Over the first two years at medical universities, students master general biological conceptions about pain as a protective body mechanism. These conceptions are basis for studying pain as a pathological process and necessary for the formation of ideas about cause-effect relationship underlying clinical manifestations of pain and are essential step in the formation of clinical thinking. The knowledge gained will help students at clinical departments in their senior years to gain knowledge about medical diagnostic process. The tasks of educators is to summarize the general biological knowledge with which students come to the department and then to form a general medical approach to understanding the causes, occurrence, and mechanisms of the pain development and pain classification. But considering the pathophysiology of pain as a separate general theme described in the section of pathology of the nervous system at the end of the course, its individual manifestations are mentioned within the framework of typical pathological conditions over the course, therefore, a certain methodological dissonance arises. In scope of studying pathophysiology of pain little information is about the feedback between pain disorders and existing somatic pathology that is important both from theoretical and practical perspectives. An interdisciplinary approach in delivering typical pathological processes on the example of pain manifestations is one of the most effective methodological tools providing the better quality of teaching pathophysiology.

Published: April 2020

Nowadays, when the nation’s temporary economic difficulties have led to a decline in the agriculture share of the overall economy, the problem of controlling weeds of agricultural land is especially urgent. Undoubtedly, in our country, with the strengthening of the economy, the use of plant protection products is growing, requiring even closer attention to the problem of the environmental impact of herbicides and the rehabilitation of soils contaminated with residues of poisonous chemicals. The general mechanism of the action affecting herbicides of different groups is the violation of redox processes, and, in particular, the increase in free radical lipid peroxidation, first of all, in gonadal cell membranes that can eventually lead to the destruction throughout the reproductive period. Moreover, they produce gonadotoxic effects leading to a decrease in steroidogenesis, and as a consequence, to impaired spermatogenesis.

The aim of the study was to investigate the gonadoprotective properties of the antioxidant complex, its effect on the parameters of lipid peroxidation, morphological and functional changes in the testes of rats exposed to the toxic effect of the clopyralid herbicide.

The introduction of this complex under the conditions mentioned above contributed not only to a significant decrease in free radical lipid perozidation in the blood and tissues of the testes, but also to normalization of the state of spermatogenic epithelium, quantitative sperm indicators, normalization of sperm motility. It has been proven the complex of antioxidants not only affects the level of spermatogenic epithelium, but also improves the quality of sperm, contributing to the restoration of sperm motility. The studies of morphological changes in the testes and the functional maturation of the sperm have shown that the most significant changes were registered during the correction with the antioxidant complex, emphasizing its more pronounced gonadoprotective effect.

The results obtained indicate the feasibility of using this antioxidant complex as gonadoprotectant in cases of chronic intoxication with herbicides.

Published: April 2020

Generalized periodontitis is a disease, which occurrence rate increases with age and manifests as a destructive inflammatory process based on the complex biochemical and pathophysiological changes. Active resorption of the alveolar ridge is influenced by both local factors and the overall body condition and systemic diseases. Development of generalized periodontitis is associated with loss of skeletal bone mass and characterized by predominance of resorption over osteosynthesis. Key moments in the pathogenesis of periodontal diseases are impairment of the dynamic balance of the prooxidate-antioxidant system that leads to the accumulation of reactive oxygen species and toxic metabolites. Along with the general mechanisms, local factors are involved into the pathogenesis of periodontitis. As a result of the "respiratory burst" of neutrophils, there is an effect of enzymatic lipid peroxidation burst with the following formation of superoxide anion radical and eicosanoids, damage to periodontal structures, immunological disorders. Generalized periodontitis is a polyetiological disease associated with the pathology of internal organs. The mechanisms of inflammatory and destructive periodontal lesions are mediated by genetic and local factors, chronic concomitant pathology, free radical aggression, and secondary immunodeficiency states. In the mechanism of local destruction of periodontal tissues, an important role is played by periodontopathogenic microflora, which triggers reactions accompanied by intensification of the processes of free radical oxidation of lipids and proteins of cell membrane structures.

Disruption in redox processes plays a significant role in the pathogenesis of hepatitis. A balance between peroxidation, on the one hand, and the antioxidant system, on the other, is a prerequisite for maintaining normal cell activity. The modern arsenal of effective hepatoprotective drugs is not so wide therefore, the development of new hepatoprotectors is one of the topical issues in pharmacology. The purpose of the work is study the antioxidant properties of medgerma in acute experimental hepatitis. Material and methods. The experiments were performed on male rats weighing 180-220 g. Acute toxic hepatitis in rats was induced by intraperitoneal administration of D-galactosamine in a dosage of 400 mg / kg (LD50). The experimental animals were divided into 4 groups: group I (n = 10) included intact animals that were injected 0.9% sodium chloride solution (control group) intraperitoneally, II group (n = 40) involved the animals receiving only D-galactosamine; group III (n = 40) included rats, which received were administered Medmerg intraperitoneally in a dose of 0.4 mg / kg 7 days before D-galactosamine administration and 7 days after D-galactosamine administration. Group IV (n = 40) included rats, which received the comparison medicine, Essentiale® N, in at a dosage of 5 mg / kg in the same mode. The assessment of lipid peroxidation indices and the antioxidant system indices were carried out on days 1, 3, and 7 after the administration of hepatotoxin in the blood serum and the liver tissue homogenate supernatant. The condition of lipid peroxidation processes in the animals with galactosamine hepatitis was assessed by the content of lipid peroxidation end products in the blood and liver tissue that react with 2-thiobarbituric acid (TBA reactants). The condition of the main components of the antioxidant system was evaluated by the level of reduced glutathione and by the activity of catalase and superoxide dismutase. Results and discussion. It has been established that medgerm enhances the liver resistance to hepatotoxicant, as evidenced by a decrease in the level of lipid peroxidation products and the consumption of main components of the antioxidant system on the first day of hepatitis. Moreover, in the rats, which received Medgerm according to prevention scheme under acute toxic hepatitis, the course of the disease was milder than in the animals that did not receive this therapy. Conclusions and prospects for further research. Medgerm possesses hepatoprotective properties, which underlay positive effects on the state of lipid peroxidation and the main components of the antioxidant system.

Multiple sclerosis has been known as one of the largest “contributor” to disability in young people worldwide, and muscle spasticity of the lower extremities is one of the challenges associated with this disease. The aim of the study was to analyze the relationship between the severity of spastic hypertonicity in the lower extremity muscles and the life quality of patients with different types of multiple sclerosis courses. The study included 43 male and female inpatients with multiple sclerosis aged 19 – 54 years (mean age was 38±9.8 years) in the exacerbation stage, who took the course of treatment at the neurological department. The participants were divided into groups according to the type of course of the disease: I group with relapse remitting course, and II group with secondary progressive course. The diagnosis was made according to the criteria of McDonald (2011). The Expanded Disability Status Scale was used to assess the extent of disability. All patients received pulse therapy with methylprednisolone for 5 days. The spasticity in the lower extremities was evaluated by the modified Tardieu Scale. Life quality indicators were evaluated using the Short Form-36 questionnaire followed by analysis of all subscales. Assessment of cognitive function was performed by applying the Mini-Mental State Examination scale for both groups. The study has shown that spasticity, as a symptom of the disease, has an impact on the quality of life depending on the type of multiple sclerosis. Spastic hypertonicity in different muscle groups affects the quality of life that should be taken into account when choosing treatment tactics. With age and duration of the disease, the patients with relapse remitting multiple sclerosis lose the ability to assess of their physical functioning, the patients with secondary progressive experience the increase in spasticity that indicates a difference in subjective perception of the disease in different types of disease.

This research is about the students’ difficulties in using English intonation. Since English is a foreign language, students always face problems especially in pronouncing the words. Pronouncing also refers to the intonation in conversation. Problem stated in this research as follow: What are the students’ difficulties in using English intonation? It focuses on the students’ intonation in a conversation, which consists of rising tone, falling tone and level tone. To answer the problem above, this research follows some theories, namely: Allen (1954), Hay craft (1971), Jones (1979), and Roach (2000). The research design is qualitative research. The subjects of this study are the second year students of SMP Negeri 2 Pematangsiantar, and the object is the student’s intonation. The technique of collecting data follows audio method or what is called recorded voice data. The data is analyzed by drawing the terminal contour of students’ intonation. The result of this research was there are three difficulties of students in using English intonation, namely: (1). Difficulty in using level tone, (2). Difficulty in using rising intonation (3). Difficulty in using falling intonation. This research finding recommends both teacher and students to take responsibility in overcoming those difficulties. An English teacher should teach his beginner students the using of intonation and its function in every kinds of sentence. Since there is an imitation process in learning intonation, a teacher should be able to detect a falling intonation from a rising intonation in his own voice as well as in a student’s. The success of learning does not only depend on the teacher but also involves the students’ awareness to learn English.

Ownership structure and risk of commercial banks in Vietnam
Authors: Tien Minh Pham , Huy Hai Bich Bui
Published: April 2020

This study examines the impact of ownership structure on bank risk. The former is classified into four types, including concentrated, institutional, foreign, and government, while the latter is proxied by the Z-score (an inverse measure of risk). The Generalized Least Squares (GLS), which controls for heteroskedasticity and autocorrelation problems, is employed to analyze an unbalanced panel data set including 21 joint-stock commercial banks in Vietnam from 2010 to 2018. We further investigate the moderating effects of market discipline (proxied by variable listed) on the relationship between ownership structure and bank risk. The results suggest that there is a negative association between three proxies of ownership structure (ownership concentration, institutional ownership, and government ownership) and bank risk and that foreign ownership does not have any significant relationship on the risk of the bank in the direct relationship models. However, the results for the models where interaction variables are included show that foreign shareholders help improve bank stability and reduce risk in listed banks. In addition, the relationship between institutional ownership and bank risk is reinforced for listed banks, while the relationships between the other two (concentration and government) and bank risk are not influenced by the listing status.

Published: April 2020

This paper presents the influence of a redundant round hole in the same direction but different cross sections on the response and failure of round-hole 6061-T6 aluminum alloy tubes subjected to cyclic bending. In this study, round-hole 6061-T6 aluminum alloy tubes with a constant hole diameter of 6 mm were drilled to obtain a redundant round hole in the same hole direction but different cross sections. The experimental results revealed that the moment–curvature relationship exhibited an almost steady loop from the beginning of the first cycle. The redundant round hole showed minimal influence on the moment–curvature relationship. However, the ovalization–curvature relationship demonstrated an asymmetrical, increasing, ratcheting and bow pattern along with the bending cycle, while the redundant round hole showed a significant influence on this relationship. In addition, six groups of round-hole 6061-T6 aluminum alloy tubes were tested, the controlled curvature-number of bending cycles required to ignite failure relationships on double logarithmic coordinates exhibited nonparallel straight lines. Finally, a theoretical model was proposed for simulating the controlled curvature–number of cycles to ignite failure. The simulation result was compared with experimental test data, which showed generally good agreement.
Artificial Neural Network Simulations of Human Learning Suggest the Presence of Metastable Attractors in Visual Memory
Authors: Chassy Philippe , Surre Frederic

The attractor hypothesis states that knowledge is encoded as topologically-defined, stable configurations of connected cell assemblies. Irrespective to its original state, a network encoding new information will thus self-organize to reach the necessary stable state. To investigate memory structure, a multimodular neural network architecture, termed Magnitron, has been developed. Magnitron is a biologically-inspired cognitive architecture that simulates digit recognition. It implements perceptual input, human visual long-term memory in the ventral visual pathway and, to a lesser extent, working memory processes. To test the attractor hypothesis a Monte Carlo simulation of 10,000 individuals has been run. Each simulated learner was trained in recognizing the ten digits from novice to expert stage. The results replicate several features of human learning. First, they show that random connectivity in long-term visual memory accounts for novices’ performance. Second, the learning curves revealed that Magnitron simulates the well-known psychological power law of practice. Third, after learning took place, performance departed from chance level and reached a minimum target of 95% of correct hits; hence simulating human performance in children (i.e., when digits are learned). Magnitron also replicates biological findings. In line with research using voxel-based morphometry, Magnitron showed that matter density increases while training is taken place. Crucially, the spatial analysis of the connectivity patterns in long-term visual memory supported the hypothesis of a stable attractor. The significance of these results regarding memory theory is discussed.
Numerical Simulation of Air Shock Wave Propagation Effects in Reinforced Concrete Columns

Published: April 2020

Reinforced concrete has been shown to be a desirable material of choice in blast resistant structures due to its availability, relatively low cost, and its inherent ability to absorb energy produced by explosions. Most research work investigating the behaviour of reinforced concrete columns to blast loading have concentrated on their response to planar loading from far-field explosions. Limited amount of work is available on the effects of near-field explosion on the behaviour of reinforced concrete columns. This study is aimed to investigate effects of explosive loads on RC column by using ALE method. Commercial finite element package, LS-DYNA is used to simulate the behavior of blast wave on RC columns. Numerical simulation is validated against experimental work done in literature. The experience gained from this research provides valuable information for the development of the finite element modeling of real blast load effects on RC columns.

Tuing waters become the main catchment area of ​​squid in Bangka Regency. Bait is one important factor in squid fishing trying to captivate the target with something as its prey is in the form of smell, taste, movement, shape and color both artificial baits and natural baits. The objective of the study was to analyze the catch of squid with different baits. The research was conducted in May 2016 in Tuing Waters of Bangka Regency. The method used in this research is the trial of catching the squid. Analysis of data used using Mann Whitney test. Taking data 4 times a month using squid fishing line. The results obtained between fishing with artificial feed and natural baits differ significantly because of Z count (2.17)> Z table (1.96), then H0 is rejected. This is because the waters of Tuing in May 2016 are not the season for the cultivation of the umi-squid. The catching season of squid occurs in November-Desenber in Tuing Waters. Squid is highly associated with environmental factors such as salinity, temperature and depth of water. Chemical Physical Factors The aquatic waters against the catch of squid.
