Authors: Novák Ján 
Published: April 2022

The research on the seminatural Western Carpathian grasslands (1992–2005) in Slovak
Republic with the altitude from 360 to 1150 m and inclination up to 28º, in the regions of Kysuce,
Orava, Liptov, Turiec, Považie, Horehronie, and Spiš presents 900 floristic analyses performed on 60 farms with the area of 9 712 ha. Regression and correlation analyses, namely pair coefficients of correlation and non-linear regression analysis (parabolic function), were used to study the correlation between the evaluation of the grassland quality (EGQ) and the selected factors (floristic group, leguminoses, other herbs and ferns in %, share of empty places in %, diversity of species, altitude and inclination). The progress of the correlation between the selected factors was analysed to set the optimal values EGQ. The diversity of species varied from 8 to 66 species, and the quality of the grassland (EGQ) varied from 8.50 to 85.38. A positive (direct) correlation was found out in case of two factors (% of grasses and leguminoses); while a negative (indirect) correlation was proved in case of the other factors (other herbs, empty places, number of species, altitude, exposition, and inclination).

Published: April 2022

The aim of the work was system analysis of organization and activity of the essential elements concerning 41 agro-tourist associations in Poland within 2001–2003. The survey was done with the help of inquiry questionnaire. The survey results allowed to create value system of coefficients describing chosen elements of analyzed associations’ organization and activity. The above coefficients described such criteria like: quantity, structure, place, time, relation, level, possession and experience. The results of the survey allowed to estimate both weaknesses and strengths of associations’ organization and activity. The survey shows the great degree of differentiation of organization elements of both associations as well as services scope and quantity. The number of associations’ members grew about 16.8% but dynamics of agro-tourist households membership was 21.4%. The dynamics of rendered services was 88.5%. Associations which rendered services assessed the quality of services high. Among 25 kinds of services – 84% gained 4.0 note and often the note was higher. The trends of the organization and activity show their essential significance for the development agro-tourism.

Abstract
Computed tomography (CT) is a routine method for the diagnosis of pathological structures in the body and has been widely used in veterinary medicine as an advanced diagnostic imagining tool in veterinary clinics. However, interpretation of CT scans requires detailed knowledge of topographical animal anatomy and usually has limited scan resolution due to the ambiguous relationship between signal intensity and tissue composition. The aim of the study was to assess the morphometric similarities between S10 plastinated slides and computer tomography (CT) scans and their usability as compatible paired diagnostic methods. A 3-year-old euthanized dog cadaver was scanned on SHIMADZU SCT/6800TXL scanner immediately post-mortem, then frozen at -80 °C to preserve the correct anatomical position, and plastinated with a standardized procedure. Semi-transparent transversal slices (5 mm) were obtained from the head, thoracic, and lumbar sections of the body. The S10 plastinated slides and CT scans contained fine and small anatomical structures with high similarity. The spatial relationships of all anatomical structures on the serial S10 platinates were in the correct anatomical position. In conclusion, S10 transversal slices showed high similarity with the CT scans and allowed identification of the corresponding morphological structures. The S10 thin plastinated transversal slices could be used for additional interpretation of CT transversal scans at veterinary clinics and as a didactical tool for veterinary students.
Vendian of the Middle Urals: Paleoclimatic reconstructions based on chemical weathering indices
Authors: Maslov A. V. 
Published: April 2022

Research subject. The clayey rocks of the Vendian Serebryanka and Sylvitsa groups on the western slope of the Middle Urals.Material and methods. The research materials comprised data on the content of main rock-forming oxides in clayey rocks (mudstones, shales, fine-grained clayey siltstones, ≈180 samples in total) with the values of losses on ignition <6 wt %. This information, obtained at the beginning of 2000 by the X-ray fluorescence method at the Institute of Geology and Geochemistry, Ural Branch of RAS, was used to calculate the average, minimum and maximum values of various weathering indices. Samples were taken from natural outcrops in the basins of the Chusovaya, Serebryanka, Sylvitsa, Mezhevaya Utka, Usva and Koiva rivers.Results. It was established that the sedimentary sequences of the Serebryanka and Sylvitsa groups, in which diamictites are present at several levels, do not exhibit a noticeable contrast in the values of various chemical indices of weathering. For example, taking into account the values of standard deviations (±1σ), the values of the Ruxton coefficient for all nine Vendian formations are statistically comparable. The same is characteristic of the average values of CIA, CIW, PIA, ICV and MIA(o) for clayey rocks of different formations. Variations in the average CPA values show that, taking into account ±1σ, only the rocks of the Starye Pechi, Garevka and Perevalok formations can be considered statistically different. Taking into account ±1σ, the clayey rocks of the Buton Formation differ significantly from the fine-grained clastic rocks of the Garevka and Kernos formations in terms of the average value of the Mg-index. The clayey rocks of the Tanin and Kernos formations have a weak or moderate positive correlation between the TiO2/Al2O3 ratio and the Ruxton, PIA, ICV indices and the hydrolyzate modulus. This suggests the dependence of the listed indicators of the intensity of weathering from the composition of rocks in paleocatchments.Conclusions. The data obtained suggest that, when averaging at the level of formations (even if the formations include quite a lot of undoubtedly glaciogenic deposits), we apparently do not record the specific contribution of the latter and, as a result, we obtain a substantially different picture than that which emerges for other Neoproterozoic deposits, including diamictites, varved clays, and intervals with dropstone.

Published: April 2022

Research subject. The transformed clastic ores (ore diagenites) of the Ishkinino Co-bearing massive sulfide deposit hosted by serpentinites of the Main Uralian Fault Zone.Materials and methods. The structures and textures of the ores were stu died. The trace element contents of sulfides and oxides were determined using LA ICP MS. The physical and chemical modeling of the diagenetic formation of accessory As minerals was conducted using the Selektor program package. Results. The clastic ores are transformed gravelites with angular and rounded clasts of serpentinites, sulfides and chromite in the psammitic matrix of the same mineral composition. No hydrothermal minerals remain in gravelites; they are replaced by crystalline pyrite-2, porous pyrite-3, anhedral pyrite-4, pyrrhotite, chalcopyrite and magnetite. Chalcopyrite and magnetite replace all sulfides, sulfarsenides, chromite and gangue minerals. Chromite occurs as fragmented crystals or inclusions into serpentinite clasts. The matrix hosts euhedral cobaltite crystals with nickeline, gersdorffite and native gold inclusions. Crystalline pyrite-2 is characterized by higher Mn, Co, Ni, Cu and Zn contents. Porous pyrite-3 exhibits higher Co, Cu and Se contents. Anhedral pyrite-4 is enriched in most trace element contents in comparison with other sulfides and pyrite generations. Chalcopyrite is characterized by higher contents of Zn and Se. Pyrrhotite contains the highest Ni and hi gher Co contents.Conclusions. The main trace elements in the ores of the deposit (Co and Ni), as well as Cu, Zn and Mn, are hosted not only in sulfides, but also in oxides. Thus, chromite contains Zn and Ni, while magnetite contains Mn and Cu. Selenium occurs in all sulfides in similar quantities. Tellurium is mostly concentrated in pyrite-4. A comparative analysis of our results with those reported on other massive sulfide deposits showed that the serpentinite-sulfide gravelites of the Ishkinino deposit had been intensely transformed during diagenesis, which resulted in low trace element contents in diagenetic sulfides. The diagenetic alteration of clastic ores led to the formation of authigenic cobaltite, gersdorffite, nickeline and native gold as a result of trace element release from primary hydrothermal minerals. Thermodynamic mode ling showed the possibility of formation of As-bearing minerals (in particular, nickeline) at temperatures of 200°C and below.

Authors: TİMUR Burcu , LALELİ KOÇ Bergen , TİMUR Hakan 
Published: April 2022

Aim: This study aimed to examine the clinical features of COVID-19 infection, maternal and fetal side effects related to infection and share experiences of our clinic in this context.
Material and MethodsA total of 63 pregnant women diagnosed with COVID-19 were identified in a tertiary hospital between September-May 2021. Disease-related symptoms, laboratory parameters, maternal and fetal side effects were examined.
Results: No statistically significant difference in age, BMI, and gestational week was detected between the groups receiving and not receiving antiviral therapy among 63 pregnant patients who were positive for COVID-19. Fever (41.2%) was the most common patients' complaint at admission.
Conclusion: The COVID-19 disease has caused a pandemic that has affected the world since December 2019. There are limited data on maternal and fetal effects in pregnancy. The increased susceptibility to respiratory tract diseases during pregnancy makes this patient group more vulnerable to the devastating effects of disease agents. In this respect, COVID-19 infection during pregnancy necessitates the closer follow-up and faster control of the disease. We obtained findings consistent with the literature in terms of symptoms, laboratory values, and obstetric prognoses of pregnant women with COVID-19 infection that we followed up in our clinic, a tertiary center.

Published: April 2022

Introduction: Childhood obesity is a principal concern worldwide. Guatemalan households have the highest prevalence of double burden of malnutrition in the world. These households are self-identified as indigenous and live with lower incomes in rural communities. However, there are limited data on risk factors for childhood obesity and limited information regarding the school environments, especially in rural communities. The objectives of this study were to determine the prevalence of overweight and obesity in a sample of rural schoolchildren, evaluate whether there is significant variability across schools, and characterize the food environment around public elementary schools in rural communities.
Methods: A cross-sectional study was conducted in four rural public schools within three villages of El Progreso, a Department (state) of Guatemala, located about 60 km east of Guatemala City. Anthropometric measures and sociodemographic information for 398 schoolchildren and their mothers were collected in 2018. Environmental audits of food outlets and food advertisements were completed for a 250- and 500-meter radius around schools. Food outlets and food advertisements were categorized as healthy and less healthy, or acceptable or not acceptable, respectively, using international protocols. One-way ANOVA was used to compare schools and continuous demographic variables. Fisher’s LSD post hoc test was used to examine differences between schools. Chi-Squared tests were conducted to evaluate differences between categorical demographic variables, overweight and obesity, and variables regarding food environments. A logistic regression was used to examine factors associated with overweight and obesity and variability across schools, adjusted for household income, child sex and age, and maternal education and age.
Results: The overall percentage of overweight and obesity among schoolchildren across all four schools was 32.4%. There was a higher percentage of less healthful food outlets compared to healthful food outlets and overall food outlets within <250 meters around the four schools, as compared to food outlets within 500 meters. Logistic regression showed that overweight and obesity status varied significantly (p=0.042) depending of the school students attended, when adjusting for household income, child sex and age, maternal education, and age.
Conclusion: Study results revealed a high prevalence of overweight and obesity among schoolchildren in rural communities in Guatemala. There was significant variability in overweight and obesity across schools. Results portray the food environment around schools as a possible contributing factor to childhood obesity.
