Among representatives of the genus Arnica L., the Arnica montana L. species is the most studied and widely used for medical purposes. However, due to the fact that the A. montana species is endangered in most European countries, the possibility to use Arnica foliosa Nutt. as an alternative source of phytochemicals is being investigated. A deeper study of the chemical composition of A. foliosa extract may give the opportunity to expand the spectrum of its possible application. The purpose of the research was to perform a detailed study of the composition and content of biologically active compounds the aerial part of A. foliosa by high performance liquid chromatography with diode array detection in combination with high-resolution mass spectrometry. Sixteen phenolic compounds were detected in ethylacetate and butanol fractions of A. foliosa. There were identified thirteen derivatives of caffeoylquinic acid and three flavonoids. In the chloroform and diethyl ester fractions, phenolic compounds were absent. It was established that the ethylacetate fraction contains big amounts of two phenolic compounds – 3,4-dicaffeoylquinic and 4,5-dicaffeoylquinic acids, and eight compounds were presented in trace or very small quantities. All sixteen phenolic compounds were found in the butanol fraction, but their total content was almost 2-fold less than in the ethylacetate fraction.

The thermophysical properties of vegetable oils were studied by differential scanning calorimetry method was used to study the fatty acid composition of vegetable oils liquid at room temperature, such as amaranth (Amaránthus), corn (Zea mays), flax (Línum usitatíssimum), sunflower (Helianthus), rape (Brusss napor), milk thistle (Sílybum mariánum), saffron milk cap (Camelina sativa) and pumpkin (Cucurbita pepo). The temperatures of the endothermic peak maxima and their area on the DSC thermograms of these oils were established as characteristic thermal effects. The interconnection between thermal effects and fatty acid composition are revealed. On the melting curves of liquid vegetable oils, up to 5 endothermic peaks of different intensities were selected in the ranges -80÷-55 °C, -40÷-15 °C, -25÷-8 °C, -19÷+6 °C and -10÷+4 °C. The coordinates of the maxima of these peaks (Ti) and their area (Si) significantly correlate with the content (Wi,%) in the oils, primarily oleic, linoleic and linolenic acids, the total proportion of which in oils is from 75 to 92%. Using the DSC thermograms of rapeseed oil as an example, it is shown that the program separation of DSC peaks allows a multiple increase in the number of analytical signals, an increase in the reliability of identification of the fat phase, and identification of the main fractions of triglycerides. DSC as a method for identifying vegetable oils using modern thermal analysis instruments is simple to sample, has good reproducibility and can be an independent method for identifying and controlling the quality of vegetable oils.

Starch is an integral part of grain of cereal crops (including barley), its content and properties significantly affect the processing and quality of products. One of the methods for increasing the variation in starch and amylose contents in starch is chemical mutagenesis. Chemical mutagens provide the possibility to obtain new allelic variations whose genes are involved in starch biosynthesis. In order to create mutant populations of barley, we used in our study the chemical mutagen phosphemide with solution concentrations of 0.002% and 0.01%. Three mutant generations (M1, M2, M3) were grown from the seeds of two barley samples (Zernogradsky 813, k-30453, Russia, var. Erectum; Dz02-129, k-22934, Ethiopia var. Nigripallidum) from the world collection of the N.I. Vavilov All-Russian Institute of Genetic Resources, after treatment with a mutagen in the field, and evaluated by a complex of selection traits. The starch content A and B and amylose content in starch were determined in the grain of the mutant and control populations of the second (M2) and third (M3) generations.
The application of mutagen led to a significant decrease in the mass fraction of amylose in the starch of the studied samples in the second (M2) mutant generation. In the third (M3) generation, the inhibitory effect was preserved only in the sample Dz02-129. In the grain of the Zernogradsky 813 cultivar in M3, the starch and amylose contents in starch were above the control. The selection of forms with the elevated content of amylose, which have potential value for the processing industry, is advisable to carry out, starting with M3.

The poor academic achievement of students in technical colleges in Nigeria has been a major concern to researchers. It is believed that the application of effective instructional methods in technical colleges could enhance overall students’ academic achievement. This demands that teachers in technical colleges should adopt instructional methods that could enhance overall achievement particularly in students’ psychomotor, problem solving achievement and enhance retention in mechanical engineering craft practice in technical colleges. The study investigated the effectiveness of constructivism instructional method on students’ psychomotor achievement, problem-solving and retention in mechanical engineering craft practice in technical colleges in Delta State. Three research questions guided the study and three null hypotheses were tested at 0.05 level of significance. The study adopted the quasi-experimental research design. Population of the study was 97 vocational II mechanical engineering craft practice (MECP) students in the six technical colleges in Delta State. A sample of 82 was used for the study. Instruments for data collection were Mechanical Engineering Craft Practice Achievement Test (MECPAT) and the lesson plans for the experimental and control groups. The instruments- MECPAT and lesson plans; were face and content validated by three experts, two from the Department of Technology and Vocational Education and one from Measurement and Evaluation Unit of the Department of Educational Foundation; all in Nnamdi Azikiwe University Awka. Test–retest method was used to establish reliability of MECPAT and was calculated using Pearson Product Moment Correlation which yielded a correlation coefficient value of 0.87. Arithmetic mean was used to analyze data relating to research questions and while analysis of covariance (ANCOVA) was used to test the null hypotheses. Findings revealed that students taught mechanical engineering craft practice using constructivism instructional method performed better, possessed requisite problem solving skills and had better knowledge retention than those taught with lecture teaching method (LTD). Based on the findings, it was concluded that constructivism instructional teaching method (CITM) is an effective and efficient mode of instruction with capacity of improving students’ learning outcome, problem solving techniques and retention ability level. Consequently, it was recommended among others that technical teachers should use constructivism instructional method in teaching mechanical engineering craft practice so as to enhance students’ psychomotor achievement in subsequent public examination.

Published: January 2021

The distribution of soil organic matter (SOM), nitrogen (N), potassium (K), total calcium carbonate (CaCO3) and pH was studied in relation to three soil tillage practices: conventional (CT) using mouldboad plough followed by three crossing of off-set disc harrow, tooth harrow and seed drill, Reduced (RT) using a chisel, and no-till (NT) using direct driller and 2 plant species: Vicia faba and Durum wheat, grown in a clayey soil of the semi-arid region of Kef (North western Tunisia) during three years 2009-2011.
Results showed that, under NT, Vicia faba increased SOM and N in the first fifteen centimeters by 20% and 84% respectively as compared to the CT, and reduced soil pH by 0.1 unit. Indeed, Vicia faba benefited from the residues of the Durum wheat. In contrast, CT buried the residues of the previous crop increasing the rate of SOM and N in the subsoil (30-45 cm depth). This made clear that NT, had the benefit of improving top-soil fertility and putting soil nutrients at the reach of the Vicia faba plant roots. Moreover, NT increased the concentration of K in the top-soil which helped seedlings and young plants resisting biotic and non biotic stresses imposed by the semi-arid environment.

Rank and Representation: A Quantitative Analysis of Female Representation Within Entry Level Faculty Positions
Authors: Nicholson Nicole 
Published: January 2021

The representation of women in leadership positions and as tenured faculty in higher education has been an issue of concern for a number of years across academic disciplines. What remains unclear is whether this trend is also observed all the way down to entry-level positions in the field of education alone. The purpose of this quantitative, correlational study was to determine if women and men occupying the non-tenured track ranks of assistant and associate professor were equally represented in the field of education at post-secondary, credential granting institutions in California (n=46). Between groups comparisons indicated that female, assistant professors significantly outnumbered men at both public and private California universities (p<0.0001), and outnumbered men as associate professors at private universities (p=0.0148). Within groups comparisons indicated that while fewer in number, a greater percentage of men occupied the rank of associate professor, thus outranking their female colleagues at public and private learning institutions (54.5% and 44.8%, respectively). However, the difference was not statistically significant.

Background. The clinical course of bronchial asthma (BA) in children is often mild. However, in real-world clinical practice it may not always be possible to attain complete control of BA symptoms. In the majority of cases cessation of basic therapy with inhaled corticosteroids (ICS) leads to a poorer BA control in spite of satisfactory general health status in patients. As a result of incomplete BA control, children demonstrate impaired activities of daily living, decreased daily physical activity and gradual reduction or withdrawal of sports participation and other activities. Under the conditions of restricted everyday activities children with mild BA and in the absence of continuous anti-inflammatory basic therapy may feel comfortable without any complaints. This may result in faulty evaluation of asthma as well controlled, which can cause disease progression.Case report. All the above mentioned situations are exemplified by the case report of a youngster suffering from mild bronchial asthma. Also, this article clearly demonstrates the significance of use of asthma control test (ACT) in real-world clinical practice in order to work out a strategy for asthma management. Besides, the role of taking a detailed medical history for correct assessment of mild BA symptom control is demonstrated. In a given clinical example we managed to evaluate, in a short space of time, everyday life changes of a youngster with mild BA (an increase in daily activities and improved quality of life) following administration of basic therapy with ICS.Conclusion. This case report demonstrates the significance of correct assessment of BA control regardless of severity of disease, in our case mild asthma, and shows its role in conducting proper basic therapy and achieving improvement of child’s quality of life.

Published: January 2021

Background. Cardiac surgery performed on pediatric patients with the use of artificial blood circulation (ABC) is accompanied by hemodilution, hypothermia and blood contact with artificial surfaces, as well as surgical trauma. All the above lead to endothelial cell injury, platelet aggregation and degranulation, activation of innate immunity, development of systemic inflammation and consumption of clotting, anti-coagulation and fibrinolytic factors, which is ultimately associated with the occurrence of thrombotic complications.Objective. The study aimed at developing a mathematical model for the prognosis of thrombotic complications in children which had undergone the ABC, based on assessment of their clinical and laboratory parameters.Methods. We have assessed clinical and laboratory data obtained from 153 children (newborn to 11 months 29 days of age) which had undergone cardiac surgery under conditions of ABC due to congenital heart defects (CHD). For all patients the general clinical and laboratory parameters: complete blood count, comprehensive metabolic panel, parameters of screening coagulogram, D-dimer concentration, von Willebrand factor activity, levels of antithrombin III, plasminogen, protein C and protein S, alpha-2-antiplasmin, thrombin activatable fibrinolysis inhibitor (TAFI) and fibrin-monomer have been assessed.Results. In 43 patients (28.1%) post-operative thromboses have been diagnosed. Examination of children revealed the presence of thrombosis of various localization including the intracardiac thrombi, ischemic cerebrovascular events, limb ischemia, etc. Based on logistic regression analysis, a model of development of thrombotic complications has been built which included 4 parameters: activity of lactate dehydrogenase (LDH), TAFI activity, von Willebrand factor activity and protein C activity. Model sensitivity was 95.3%, and its specificity — 96.4%.

Published: January 2021

Background. Studying the metabolic activity of gut microbiota has diagnostic value as it allows determination of the extent of microbiota perturbation, which is an important indicator of the post-operative gastrointestinal tract function.Objective. The study aimed at investigating the metabolic activity of gut microbiota in children during their first year of life which had undergone partial bowel resection.Methods. The spectrum of fecal short chain fatty acids (SCFA) was assessed using gas-liquid chromatography (GLC). Also, a comparative analysis of clinical and anamnestic data in children of the first year of life which had undergone partial bowel resection versus apparently healthy children was carried out.Results. Dynamic follow-up of children which had undergone bowel surgery revealed a reduction in acetic acid (С2) fecal level and increased propionic acid (С3) and oleic acid (С4) levels by the end of the first year of life. An age-adjusted comparative estimate has shown that the markers of anaerobic microflora, specifically, the level of propionic acid, are also high at the age of 7–12 months. A comparative analysis of metabolic activity of gut microbiota in children which had undergone bowel resection revealed lower fecal levels of oleic acid and higher total fatty acid content as compared to healthy children.Conclusion. Children which had undergone bowel resection, by the end of first year of life, have higher anaerobic and lower aerobic activity of gut microflora. A comparative analysis of metabolic activity of gut microflora in children which had undergone surgical treatment versus children of health groups I and II demonstrated the absence of significant differences between obligate (С2) and anaerobic (С3, anaerobic index [AI]) bacteria. However, lower fecal С4 values have been found in post-operative children during their second half-year of life, which may attest to persistent inflammation of the gut. Total fecal acid content throughout the entire follow-up period was higher in children which had undergone bowel resection, which reflects the activation of gut microbiota characterized by its species diversity.
