Authors: Kolesnikova I. Yu. , Novikova A. S. 
Published: June 2021

Aim. A study of atrophic gastritis severity and rate in patients with gastric polyps (GP).Materials and methods. The study enrolled 61 patients with hyperplastic (HGP) and 41 — with adenomatous GP (AGP). All patients had 24-h gastric pH-metry, control of the pepsinogen I, II and gastrin-17 levels, in addition to a general clinical, endoscopic, histological examination and testing for Helicobacter pylori.Results. GP patients had benign manifestations prevailed with epigastric heaviness and overflow, and a scarce history of H. pylori testing at no control of rendered eradication therapy. A symptomatic proton pump inhibitor treatment in GP was either prescribed or voluntary. Focal atrophic gastritis in endoscopy was revealed in 12 (19.7 %) HGP and 16 (39.0 %) AGP patients, diffused atrophic gastritis — in 49 (80.3 %) HGP and 25 (60.9 %) AGP patients. Low-grade chronic gastritis in histology prevailed in HGP, moderate — in AGP, and severe — in 21.9 % cases. Moderate (27.9 %) to severe (65.6 %) atrophy of gastric mucosa was registered in HGP, with 53.7 and 39.0 % respective AGP cases. Polyp dysplasia was detected in 20 % HGP and 75.6 % AGP cases. Pepsinogen I <25 µg/L at a pepsinogen I/II ratio ><3 was observed in 38 (62.3 %) HGP and 18 (43.9 %) AGP patients. Hypo- and anacidic were 65.6 % HGP and 31.7 % AGP patients. >H. pylori-positive were 52.5 % HGP and 70.7 % AGP cases.Conclusion. A largely similar aetiopathogenesis of gastric polyps and chronic atrophic gastritis warrants the H. pylori diagnosis and a more detailed patient control for chronic gastritis grading and staging, functional insufficiency of gastric mucosa and the severity of hyperplastic and dysplastic change. The H. pylori eradication, in contrast to anti-secretory therapy, allows the containment of chronic gastritis and is a critical measure in gastric cancer prevention.

Published: June 2021

Morphology in forest soils has developed over a long time due to the non-intensive management of forest soils. Damage to forest soil occurs when there is logging activity, fire, or land use change. Some forest was used as productive land for example agroforestry and forest production. As with landuse in agriculture, intensive management of forests can also reduce soil productivity. Inaccuracy forest land use would cause environmental or economic damage, so basic soil management data in forest areas is needed. However, the soil morphology of the Ayer Hitam Forest Reserve (AHFR) in Malaysiahas never been observed. The objective of this study is to assess the soil characteristic and soil morphological properties of theAHFR. Studying the characteristics of soil morphology in toposequent conditions is necessary to find out the differences in soil from different heights and the effects of erosion, transportation, and deposition on the soil. This study was conducted in the AHFR, Puchong, Selangor Darul Ehsan, Peninsular Malaysia. Mapping of the area under investigation was carried out by conventional soil survey techniques with a physiographic approach using maps with a scale of 1:30,000. The results showed that AHFRhas some different soil morphological characteristics and classification in subgroupamong five different slope positions with similar soil order, which is a Ultisol soil. The soil in the AHFRis formed from highly weathered soil due to high rainfall in this location.The results of this study are important for soil development, identification management, and land use priority such as erosion control on steep-slope forest areas, regeneration and reforestation, and it can also be used for forest education, practice, research, and training activities.Keywords: Ayer Hitam Forest Reserve, forest soil, soil morphology, toposequent, Ultisol soil

In this study, technical lignin from black liquor was used as a pre-polymer for the preparation of bio-polyurethane (Bio-PU) resins. Briefly, the isolated lignin was fractionated using ethyl acetate (EtAc) and methanol (MeOH). The liquid fractions of lignin, such as lignin-EtAc (L-EtAc) and lignin-methanol (L-MeOH), were mixed with 10% of polymeric isocyanate (based on the weight of liquid fractions) to obtain Bio-PU resins. The isolated lignin, fractionated lignin, and lignin-derived Bio-PU resins were characterized using several techniques. The obtained Bio-PU resins were then used to modify ramie fibers using vacuum impregnation method. Fourier Transform Infrared (FTIR) spectroscopy, Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA) revealed that the isolated lignin had quite similar characteristics to the lignin standard. Fractionation of lignin with EtAc and MeOH altered its characteristics. FTIR, DSC, and TGA showed that solid fractions of lignin had similar characteristics to lignin standard and isolated lignin, while the liquid fractions had characteristics from lignin and the solvents. The absorption band of isocyanate (−N=C=O) groups was shifted to 2285 cm−1 from 2240 cm−1 owing to the reaction with the −OH groups in lignin, forming urethane (R−NH−C=O−R) groups at 1605 cm−1 in Bio-PU resins. Thermal properties of Bio-PU resins derived from L-EtAc exhibited greater endothermic reaction compared to Bio-PU-L-MeOH. As a result, the free −N=C=O groups in Bio-PU resins have reacted with –OH groups on the surface of ramie fibers and improved its thermal properties. Modification of ramie fibers with Bio-PU resins improved the fibers’ thermal stability by 15% using Bio-PU-LEtAc for 60 min of impregnation.Keywords: Bio-polyurethane resins, Impregnation, Lignin fractions, Ramie fibers, Thermal stability

Memento mori as Repetition of Finitude: Death beyond Heidegger and Levinas
Authors: Turcan Nicolae 
Published: June 2021

Exemplified especially by Heidegger and Levinas, the phenomenology of death expresses first, the impossibility of the death experience, second, the authenticity of Dasein starting from the horizon opened by the possibility of death, and third, the relevance of the death of the other to the discovery of one’s own death. This article tries to take a step further, showing the link between the authenticity of Dasein and the desire for immortality manifested in this authenticity. By overturning Heidegger’s theses and by affirming both the necessity of an authentication of death itself—in accord with Socrates’s death example—and the legitimacy of the meditation on death, this text links the need for immortality, which is phenomenologically visible, with the Christian faith in the resurrection, which is visible only for theology.
Female Soul and Feminine Spirit: Philosophical Prolegomena to a New (Women) Culture in the Interwar Radio Lectures Alice Voinescu’s and Constantin Noica’s.

Published: June 2021

Female Soul and Feminine Spirit. Philosophical Prolegomena to a New (Women) Culture in the Interwar Radio Lectures Alice Voinescu’s and Constantin Noica’s. The newly founded Romanian Radio (1927) invited since 1930 the most important personalities of the Romanian culture to speak in the frame of different radio conferences. Two of these personalities were the philosophers Alice Voinescu (1885-1961) and Constantin Noica (1909-1987). Although they represent two different philosophical orientations (Alice Voinescu as a post-metaphysical thinker and Constantin Noica as a philosopher, who tries, like Heidegger in the German culture, to rebuild metaphysics), the two interwar Romanian thinkers meet each other in some philosophical topics. One of these is the critical manner, how they are thinking about the movement of the emancipation of women in the 20thcentury. Both of them agree that the female soul and the feminine spirit have not to lose their specific features in the tendency to become active in the frame of the public sphere. In their critical thinking, Alice Voinescu and Constantin Noica meet the philosophical ideas of German philosophers like Georg Simmel and Martin Heidegger.

The protective effects of red cabbage and garlic extracts against liver, kidney and thyroid gland damage induced by fumonisin B1 (FB1) in male mice were studied. Sixty mice divided in to six groups. Group one are the healthy mice, Group two are mice that received a daily oral dose of only FB-1 (100 µg/kg.b.w) for 1 month, Group three: are mice that received red cabbage extract (500 mg/kg.bw) plus FB1, Group four: are mice that received red cabbage extracts, Group five: are mice that received garlic extract (500mg/kg.bw) plus FB1, group 6:are mice that received only garlic extract. After finishing the experiments, samples of blood were used for biochemical examination. The results indicated that group (2) mice treated with fumonisin B1 had significantly increased levels of immunoglobulins (IgG and IgM), kidney function parameters (urea and creatinine), proteins (albumin and total protein (TP)), and thyroid hormones (T3 and T4), along with significantly decreased level of TSH (p < 0.05). In the LD50 experiment, we are choose concentration (100 µg/kg.b.w) gavage to the mice. Oral administration red cabbage garlic extracts produced significantl reduction the levels serum IgG, IgM, T3, T4, urea, creatinine, TP and albumin and with a significant increase in TSH.

Published: June 2021

A dynamical system describes the consequence of the current state of an event or particle in future. The models expressed by functions in the dynamical systems are more often deterministic, but these functions might also be stochastic in some cases. The prediction of the system's behavior in future is studied with the analytical solution of the implicit relations (Differential, Difference equations) and simulations. A discrete-time first order system of equations with quadratic nonlinearity is considered for study in this work. Classical approach of stability analysis using Jury's condition is employed to analyze the system's stability. The chaotic nature of the dynamical system is illustrated by the bifurcation theory. The enhancement of chaos is performed using Cosine Chaotification Technique (CCT).
Simulations are carried out for different parameter values.

The effect of myeloid leukemia, especially cute myeloid leukemia (AML), has been widely noticed on the parameters of liver and kidney functions and the levels of certain hormones. This study aimed to evaluate a number of biochemical parameters of liver and kidney functions and hormones in Iraqi subjects with newly diagnosed acute myeloid leukemia. Eighty newly diagnosed AML adult patients (40 males and 40 females) and forty healthy individuals (20 males and 20 females) with an age range of 16-75 years were involved in this study during their attendance at the Hematology Department of Baghdad Teaching Hospital/ Medical city in Baghdad province from March 2019 to February 2020. Blood samples were collected from all subjects for the determination of serum levels of the parameters of liver function parameters., kidney function , lactate dehydrogenase (LDH), and Erythropoietin (EPO). The results showed that the serum levels of liver function parameters (alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) had highly significant increases (p< 0.01) in AML patients (85.87±2.49 , 53.93±1.76, 150.87±7.04 U/L, respectively) as compared to the control (30.58 ±2.04, 22.89 ±0.97, 75.51 ±2.12 U/L, respectively ). Also, the level of kidney function parameters (blood urea, creatinine and uric acid) showed highly significant increases (p< 0.01) in AML patients (58.82 ±1.49, 1.831 ±0.05, 8.34 ±0.15 mg/dl, respectively) as compared to the control (31.10 ±1.03, 0.850 ±0.02, 4.81 ±0.14 mg/dl, respectively). In addition, the level of LDH showed a highly significant increase (p< 0.01) in the patients with AML (657.72 ±80.76 U/L) as compared to the control (166.05 ±6.15 U/L). Moreover, the level of EPO showed a highly significant increase (p<0.01) in the patients with AML (11763.80 ±329.46 pg/ml ) as compared to the control (316.94 ±34.42 pg/ml).

Relevance. Atherocalcinosis is a prognostically unfavorable pathology that is often found in the general population and, especially, in the liquidators of the consequences of the accident at the Chernobyl nuclear power plant. Its pathogenesis has not been sufficiently studied, as well as its treatment.Intention: To establish relationship between the severity of coronary artery calcinosis and biomarkers of inflammation, bone metabolism and vascular calcification in liquidators of the consequences of Chernobyl accident at a remote period. Methodology. The study group was made up of 90 liquidators of the consequences of the Chernobyl accident – men aged 40 to 78 years, the median – 59 years, at the time of participation in emergency recovery work they were from 18 to 53 years old. Proteins of inflammation, osteocalcin, mineral metabolism, osteopontin, osteoprotegerin, fetuin A in patients’ blood serum were analyzed. Expression of coronary vessel calcinosis was evaluated on the basis of multispiral computed tomography data with determination of calcium index by Agatston method, peculiarities of bone mineral density change depending on cardiac calcinosis severity in persons who participated in the aftermath of Chernobyl accident suffering from atherosclerosis.Results and Discussion. Liquidators of the consequences of the Chernobyl accident with reduced bone mineral density were more likely to have a high and extremely high degree of coronary artery calcinosis (65 %) than patients without osteopenia (49 %). The serum level of osteocalcin in patients with reduced bone mineral density was significantly greater than in the subgroup with unchanged bone mineral density. It has been established that in liquidators of the consequences of the Chernobyl accident, inflammation with high values of C-reactive protein and leptin in the blood was associated with reduced fetuin A levels. In the liquidators of the consequences of the accident at the Chernobyl nuclear power plant with a calcium index of more than 400 points, osteoprotegerin was statistically significantly higher, and the level of fetuin was statistically significantly lower than in other patients.Conclusion. Changes in calcium metabolism and bone mineral metabolism as well as systemic inflammation are closely related to the change in the calcium index in liquidators of the consequences of the Chernobyl accident with coronary heart disease and, along with instrumental diagnostic methods, may reflect the degree and severity of vascular injury. In addition, the study of the mechanisms of formation of cardiac calcinosis is extremely important due to the fact that they can be targets for pharmacological intervention, the effects of which will change the nature of atherosclerosis progression.
