    About Grid Generation in Constructions Bounded by the Surfaces of Revolution

    Full text link
    For constructions bounded by the surfaces of revolution, structured grid generation technique is presented. Its technology has been elaborated within the variational approach for constructing optimal grids satisfying optimality criteria: Closeness of grids to uniform ones, closeness of grids to orthogonal ones and adaptation to a given function. Grid generation has been designed for numerical solution of the differential equations modeling the vortex processes of multi-component hydrodynamics. In the technology, the three-dimensional construction in which it is required to construct a grid is represented in the form of the curvilinear hexahedron defining its configuration. The specific feature of the required configurations is that some faces of a curvilinear hexahedron lie in one plane and along edges of adjoining faces grid cells degenerate into prisms. Grid generation in the considered constructions has started to be developed by the elaboration of algorithms for the volume of revolution which has become the basic construction. The basic construction is obtained by the rotation through 180Β° around the axis of a generatrix consisting of straight line segments, arcs of circles and ellipses. Then the deformed volumes of revolutions are considered along with the generalizations of the volume of revolution which represent constructions obtained by the surfaces of revolution with parallel axis of rotation. The aim of the further development of the technology is to consider more and more complicated constructions and elaborate the technology for them. In the presentation, the current state of the development of the technology is given. Examples of generated grids are supplied. Β© 2021 Institute of Physics Publishing. All rights reserved

    Heart diseases, especially acute coronary syndrome (ACS), are among the most severe illnesses that often lead to death. Despitesignificant advances in the prevention and treatment of ACS, the incidence of the disease and its complications are very serious. +eimbalance between pro- and antioxidant systems, the formation of active carbonyl compounds, and the end products of glycation inthe blood and tissues are the key moments in the development of heart and neurological disorders leading to a change of behavioralresponses. So, the search for antioxidants with cardio- and neuroprotective effects is an urgent task. +is study was aimed atevaluating the effects of Corvitin and 2-oxoglutarate on physiological parameters, heart histology, and markers of carbonyl/oxidativestress of rats with pituitrin-isoproterenol-induced myocardial damage (PIMD). Increased sweating, tachycardia, significantly decreasedlocomotor and exploratory activity, changes of ECG, heart histology, and biochemical changes were observed in the PIMDgroup.+e administration of Corvitin or 2-OG led to the recovery of locomotor and cognitive activities of the rats, improvement inheart histology, a decrease in the levels of thiobarbituric acid reactive substances, advanced glycated end products, and variouschanges in the activity of the antioxidant enzymes, 6 days after PIMD. So, Corvitin and exogenous 2-OG show cardio- andneuroprotective effects through the decrease of carbonyl/oxidative stress and regulation of the activity of the antioxidant system

    The algorithm for generation of structured grids in deformed volumes of revolution

    Full text link
    For the volume of revolution deformed by another volume of revolution, a grid generation algorithm is suggested. The algorithm is designed for multimaterial hydrodynamic simulation and for solving other physical and engineering problems. The algorithm represents the non-stationary procedure generating three-dimensional structured grids in domains with moving boundaries. The algorithm is developed within the variational approach for constructing optimal curvilinear grids. The volume of revolution is obtained by the rotation about the axis through 180Β° of a plane generatrix curve consisting of straight line segments and arcs of circles. The non-stationary algorithm is the iterative process at each stage of which the deformation of a grid and then its optimization are carried out. The deformation of a grid is implemented within the geometrical approach, and the optimization of a grid within the variational approach. Iterations are continued until the necessary deformation is reached. The algorithm is realized in the computer code written in C++. Β© Published under licence by IOP Publishing Ltd

    Topicality. The main disadvantage of the first-line anti-TB drugs isoniazid and rifampicin is their ability to cause drug-induced liver injury. At the same time, in addition to hepatotoxic, in 12-24 % of cases are neurological disorders. The consequence of these processes is a disturbance of synaptic plasticity, learning processes and memory. In addition, significant factor in the development of neurological disorders may be an imbalance of intestinal microflora. One of the possible options at eliminating or attenuating the manifestations of cognitive deficiency in various pathological conditions is the appointment of drugs with neuroprotective properties. However, even today their effectiveness studied not enough for central nervous system dysfunctions arising from prolonged anti-TB therapy. Therefore, we can assume that neurological disorders can be due to a complex of interrelated factors.Aim. To determine the morphometric and ultrastructural features of neurons and glial cells, as well as the levels of glial fibrillary acid protein (GFAB) in the hippocampus of rats under long-term administration of isoniazid and rifampicin during experimental therapy with a fixed combination of ipidacrine hydrochloride/phenibut.Materials and methods. Studies were conducted on three groups of white Wistar male rats with drug-induced hepatitis, reproduced by intragastric administration of isoniazid and rifampicin for 28 days. In the last 14 days of the intragastric experiment, rats of the research group were administered ipidacrine hydrochloride/phenibut (1/60 mg/kg). The content of cytosolic GFAP in the hippocampus was determined by competitive enzyme-linked immunosorbent assay. Semi-thin sections of CA1 sections of the rat hippocampus were analyzed, Image J. analysis program used. The ultrastructural characteristics were studied, PEM-100-01 transmission electron microscope used (Selmi, Ukraine).Results and discussion. Under the experimental pharmacotherapy the specific number of degeneratively altered neurons was significantly lower than in the controlled animals. At the same time, astrocytes were characterized by significantly less edema of the cytoplasm and adaptive-compensatory changes in mitochondria, and the content of cytoplasmic GFAP was 44.2 % (P = 0.0065) lower than the group of animals with hepatitis.Conclusions. Course administration of ipidacrine and phenibut reduces the severity of neurodegeneration appearance, improves the state of astroglia in the hippocampus, and it also reduces the cytoplasmic levels of glial acidic fibrillary protein in animals with drug-induced liver injury.ВступлСниС.

    Introduction. The development of a malignant tumor naturally affects renal function. During tumor formation, the renal tissue is destructed either by direct invasion into the parenchyma, or by mechanical change in the renal architecture caused by compression of the renal parenchyma, collecting ducts, tubules, and nephrons. In addition, a tumor can secrete biologically active substances, which have an indirect negative influence the functional state of the organ. Currently, it has been established that kallikrein-kinin and renin-angiotensin-aldosterone systems play an important role in the development of nephropathy of various genesis. At the same time, these systems' role in the development of renal function disorders in the setting of tumor damage has not yet been studied.Purpose of the study. To study changes in the components of the kallikrein-kinin and renin-angiotensin-aldosterone systems in the case of localized kidney cancer.Materials and methods. Forty-five patients diagnosed with T1N0M0 kidney cancer and 13 relatively healthy patients without cancer were examined. The determination of the components of the systems under study was carried out by the kinetic method after chromatography of blood plasma and urine using DEAE-Sephadex A-50 (Amersham Biosciences Corp., Sweden). The indices of angiotensin-1, renin, aldosterone, and cortisol were studied by an indirect method of radioimmunoassay. Statistical processing was carried out using Statistica 8.0 software (StatSoft Inc., IBM Corp., USA) by means of the Student-Fisher test (p < 0.05).Results. The development of kidney cancer is accompanied by a 2.3-fold increase in the activity of kallikrein and other trypsin proteases with a significant deficiency of their inhibitors (p < 0,05). Against this background, there is a 1.3-fold decrease in the cortisol/renin ratio from a 2.9-fold and 2.3-fold increase in the values of the renin/angiotensin-I and cortisol/angiotensin-I interaction ratios, respectively, compared with the normal values of these indicators (p < 0,05).Conclusions. Renal cell carcinoma is accompanied by trespassing of local metabolism with the formation of tubulointerstitial dysfunction and a shift of the proteinase-inhibitory balance towards proteolytic activation

    The purpose is to evaluate the detoxification effects of the polymyxin sorption columns and filtration detoxification using polymethyl methacrylate membranes in abdominal sepsis in cancer patients.Materials and Methods. We examined 226 patients with oncological diseases of abdominal organs complicated by abdominal sepsis postsurgery. In 50 cases, septic shock was reported. In 173 patients an acute renal injury (ARI) was diagnosed in the structure of organ failures, of which a combination with acute respiratory distress syndrome (ARDS) was diagnosed in 61 patients. The severity was 26.3Β±3.3 points (APACHE-II scale), 10.2Β±2.5 points (SOFA scale), and 4.3Β±1.8 points (qSOFA scale). Microbiological identification was obtained in 155 (68.6%) cases. The polymyxin column sorption was used in 86 patients 2–6 hours after sepsis was diagnosed with the EAA greater than 0.5. The blood flow rate was 80–150 mL/min; the duration was 120–240 min; the sorption frequency was 2–3 sessions at a 24-hour interval. If ARI and ARDS were developed, detoxification by filtration using a dialyzer with a BK-1.6F polymethylmethacrylate membrane was included in the complex treatment of 144 patients. The detoxification was carried out for 8–12 hours changing the dialyzer every 4 hours.Results. A statistically significant decreases of hyperthermia, leukocytosis, neutrophilia, procalcitonin, and the EAA test values were revealed after the completion of the sorption treatment. Normalization of hemodynamic parameters, increase of the oxygenation index, and SOFA scoring decrease by 5.6Β±2.1 points (P<0.05) were found. PCT and IL-6 blood levels decreased from 6.7Β±2.7 ng/mL to 2.3Β±0.6 ng/mL and from 7300Β±7700 pg/mL to 860Β±180 pg/mL,Β respectively, as determined 60 minutes after completion of filtration detoxification procedure (P<0.05). The SOFA index decreased by 4.1Β±1.1 points (P<0.05).Conclusion. The use of polymyxin column sorption and filtration detoxification using a polymethyl metacrylate membrane improves the results of treatment of abdominal sepsis in cancer patients.ЦСль исслСдования – ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ дСтоксикационныС эффСкты использования ΠΊΠΎΠ»ΠΎΠ½ΠΎΠΊ с полимиксиновым сорбСнтом ΠΈ Ρ„ΠΈΠ»ΡŒΡ‚Ρ€Π°Ρ†ΠΈΠΎΠ½Π½ΠΎΠΉ дСтоксикации с использованиСм ΠΌΠ΅ΠΌΠ±Ρ€Π°Π½Ρ‹ ΠΈΠ· ΠΏΠΎΠ»ΠΈΠΌΠ΅Ρ‚ΠΈΠ»ΠΌΠ΅Ρ‚Π°ΠΊΡ€ΠΈΠ»Π°Ρ‚Π° ΠΏΡ€ΠΈ абдоминальном сСпсисС Ρƒ онкологичСских Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ….ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π» ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

Inclusion of plant inedible biomass seems to be necessary for closure increase of mass exchange processes of a long-functioning BTLSS. The work presents estimation data of three ways of processing wheat and radish inedible biomass introduced into the SLS: a β€˜biological’ method, a physical-technical way and a combined one. Radish (Raphanus sativus L.) β€œMokhovsky” variety was a test culture. The β€˜biological’ method represented the SLS used as a bioreactor in which dry wheat and radish inedible biomass was introduced. The physical-technical method consisted of β€˜wet’ oxidation of wheat and radish inedible biomass by hydrogen peroxide in alternating current with further introduction of the solution obtained into the solution for plants irrigation. The combined method included physical-chemical mineralization of wheat straw and radish inedible biomass introduced directly into the SLS. The combined method consisted of the physical-chemical oxidation of wheat straw and the β€˜biological’ processing of radish inedible biomass appeared to be the most optimal way from all methods under stud

    Male factor is the reason of infertility in almost half of marriages. Infertile men have the percentage of sperm with violations of DNA integrity of over 30 %; with that, healthy fertile men have that indicator of less than 15 %. Understanding of importance of damages of sperm DNA is growing with distribution ofauxiliary reproductive technologies. As of today, these consequences have not been studies yet, and the therapeutic effect of intake of antioxidants has not direct correlation with the sperm DNA fragmentation level. Docosahexaenoic acid is one of the most valuable omega-3 polyunsaturated fatty acids for human health. Docosahexaenoic acid is the main component of the brain gray matter, retina, testes, and sperm cell membranes. In connection with that, a study was held the purpose of which was to assess the effect of the nutraceutical enzymatic docosahexaenoic acid triglyceride (BrudiPlus) in high concentrations on damaged sperm DNA of patients with idiopathic pathozoospermia. 40 patients with idiopathic pathozoospermia and the level of DNA fragmentation over the statutory value took part in this study. The following positive results were received: intake of BrudiPlus allowed decreasing sperm DNA damages and improving of antioxidant system of sperm

    Diabetes mellitus is one of the most serious medical, social, and economic health problems in all countries of the world. The incidence of diabetes mellitus in the world doubles every 10–15 years, acquiring the character of a non-infectious epidemic. Therefore, it is extremely important to search for new drugs that help normalize glycemia, prevent complications of diabetes mellitus, and improve the quality of life of patients. These drugs include β€œNeo inulin”, which has a hypoglycemic, antioxidant, hepatoprotective and angioprotective effect.The aim: to evaluate the effectiveness of β€œNeo inulin” in the complex treatment of patients with type 2 diabetes mellitus.Materials and methods. The study involved 18 women (average age – 64.5 Β± 8.7 years, average weight – 77.8 Β± 11.4 kg) and 3 men (average age – 54.6 Β± 12.4 years, average weight – 114 Β± 40.2 kg). The average duration of type 2 diabetes was 11.0 (7.0–12.0) years. β€œNeo inulin” was prescribed as 2 capsules per day for 12 weeks in the complex of basic diabetes therapy To assess the effectiveness of therapy, a study of the quality of life related to health, a biochemical blood test (glycated hemoglobin), a clinical minimum (CBC, OAM, ECG, blood glucose) was carried out, the functional characteristics of tissue blood flow were investigated, and the ankle-brachial index (ABI) was determined. Statistical processing of the results was carried out using the Statistica 6.0 software package (StatSoft Inc., USA). Differences were considered statistically significant at p < 0.05.Results. Statistically significant differences were revealed in the values of all scales of health-related quality of life in patients in the groups before and after treatment with β€œNeo Inulin”, including the total physical and mental components. An improvement in the functioning of microcirculatory regulation mechanisms was noted, which is confirmed by a statistically significant increase in ABI (1.0 and 0.8 on the right; 0.9 and 0.8 on the left, respectively; p < 0.05) and the coefficient of microcirculation variation (9.2 and 8.3, respectively; p < 0.05). In 57,1 % of cases (12 people), the level of glycated hemoglobin was normalized.Conclusion. The use of a treatment regimen that includes β€œNeo Inulin” improves the effectiveness of treatment and improves the quality of life of patients with type 2 diabetes mellitus
