Ability to foster schoolchildren’s ecological literacy as a result of prospective biology teachers’ professional training
(Lithuania, 2020-12) Bilianska, Mariia; Yaroshenko, Olga
An important role in preventing the negative effects of human impact on the environment is played by environmental literacy, which is connected with developing the ability to use natural resources wisely and reduce waste as well as awareness of the role of the environment for safe and healthy living. The scientific studies on formation of students’ ecological literacy were analyzed. It was revealed that the current state of training future Biology teachers for developing students’ environmental literacy is not efficient. Ability of prospective Biology teachers to form students’ ecological literacy is identified by the unity of value, cognitive and procedural components. Theoretical substantiation of the technology of training future Biology teachers for increasing students’ ecological literacy is carried out. The peculiarity of the technological process is the study of the elective courses “Conducting Ecological Pedagogical Activities”, “Technologies of Environmental Education and Upbringing”, “Methods of Teaching Ecology”, use of interactive teaching methods, combination of training sessions, independent work, practical training, and control measures. Criteria for the formation of each component are students' attitude to the environment and its preservation, the level of knowledge acquisition, the level of mastery of the methods of developing school students’ environmental literacy. A three-level approach to evaluating the results was used. The average level of formation of each component dominated. During the experimental training, statistically significant positive changes in the formation of each component took place. This confirms the feasibility of further implementation of the technology.
Allelopathic Effect of Cucurbitaceae Species on Triticum aestivum L. Cultivars
(Slovak University of Agriculture in Nitra, 2024) Ostapchuk, Anastasia; Kustovska, Alla
This study investigates the allelopathic interactions between Triticum aestivum L. (wheat) cultivars Podolyanka and Bogdana and several Cucurbitaceae species, including Cucurbita pepo L., Cucurbita pepo var. Giraumontia Pang., and Cucumis sativus L. The experimental analysis was focused on wheat’s seed germination, root length, and shoot length under the influence of aqueous extracts from these cucurbits. As the result, inhibitory effect was revealed depending on the combination of wheat variety and cucurbit species. The most substantial inhibitory impact was observed with Cucumis sativus on cv. Podolyanka. The aqueous extracts of Cucumis sativus significantly reduced germination percentage and affected early seedling growth, which indicates strong allelopathic effect. Meanwhile, with Cucurbita pepo and its variety Giraumontia variable effects were observed ranging from slight inhibition to no inhibition, depending on the wheat variety. These findings highlight the allelopathic potential of cucurbits and their possible applications in crop management, particularly for weed suppression and optimizing plant growth. Additionally, the study emphasizes the importance of understanding species-specific allelopathic influences, as these interactions can lead to improved crop rotation and intercropping strategies, ultimately enhancing overall agricultural sustainability. The results of this research can be used to optimize crop performance and develop sustainable agricultural practices that reduce reliance on chemical herbicides. The study provides insights into crop-weed dynamics and serves as a foundation for future research on the allelopathic effects, including the identification of specific allelochemicals responsible for the observed interactions, their modes of action, and their practical applications in agriculture. These results contribute to a broader understanding of plant-plant interactions and offer potential pathways for reducing chemical inputs in farming systems while maintaining productivity and ecological balance.

Analysis of the dynamics of refraction disorders in schoolchildren troughout the year
(WOMAB, 2021) Plyska, O. I.; Kharchenko, L. B.; Grusha, M. M.; Lazoryshynets, V. V.; Shkrobanets, I. D.
The article used a retrospective analysis to investigate the state of the visual system of students of different ages and genders. For this purpose, refractive errors (myopia, hyperopia, astigmatism and myopia or hyperopia with astigmatism) and contrast sensitivity in the dynamics of the year were determined. There was an incredible increase in refractive errors (from 60.12 % to 65.32 %): myopia (from 33.53 % to 36.88 %) and hyperopia (from 20.23 % to 21.97 %). The study of contrast sensitivity revealed its reduction from 2.5 (limit value) to 2.0 in 10.15 % of cases. The use of corrective means prevented the progression of refractive errors. At the same time, their non-use is accompanied by the progression of refractive errors in 97.67 %. It was found that the limit value of the contrast sensitivity index =2.5 is important for further prediction of changes in the visual system of schoolchildren and can be used for preclinical rapid diagnosis of visual impairment. Students with contrast sensitivity 2.5 are at risk and need careful monitoring of their refractive apparatus for a long time, which allow us to detect refractive errors of the visual analyzer in the early stages and to apply corrective means in a timely manner

Biochemical characteristics of corn grain under the presowing seed treatment with rhizobacteria Paenibacillus polymyxa KB and chelate complex of biogenic silicon
(2023) Kuchmenko, Olena; Havii, Valentyna; Sheiko, Vitalii; Machulskyi, Hryhorii; Zhuravel, Nataliiа; Kustovska, Alla; Biliavskyi, Serhii
We used corn seeds of maize (Zea mays L.) of the Dnieper 196 SV hybrid to analyse presowing seed bacterization and treatment with biogenic silicon that could be promising in growing maize hybrids. Using presowing seed bacterization and treatment with biogenic silicon resulted in the total protein and fibre content increasing by 3 times-4 times and 21-27%, respectively. The mono- and disaccharide content increased by 2-3 times and the starch content decreased up to 10%-20% in corn grains under treatment with both preparations. During presowing seed bacterization, malondialdehyde content increased, whilst the ascorbic acid content, catalase and ascorbate peroxidase activity, and antioxidant activity reduced. Using presowing seed treatment with BSi resulted in the malondialdehyde content decreasing and the activity of catalase and ascorbate peroxidase increasing. This agricultural method leads to an increase in the protein, carbohydrate, and fibre content, which is valuable in terms of their nutrition. Both variants of presowing seed treatments are promising in growing maize hybrids.

Blackfruit cornel (Cornus sessilis Torr. ex Durand) - introduction and adaptation strategy in the Forest-Steppe of Ukraine
(Національний медичний університет імені О. О. Богомольця, 2025-01-28) Klymenko, Svitlana Valentynivna; Kustovska, Alla Valentynivna
Plant introduction is a justified desire to enrich the species composition of plants with new plants useful for agriculture, in particular, for horticulture. In this regard, the polymorphic family Cornaceae Bercht. and J.Presl, which is represented by a large number of fruit, medicinal, and ornamental plants, is of great value. Cornaceae, the dogwood family, is the largest family in the order Cornales, though it has just two genera - Cornus (65 species) and Alangium (20 species) [1, 2]. The family primarily distributed in northern temperate regions and tropical Asia. In northern temperature areas, Cornaceae are well known from the dogwoods Cornus. In the M.M. Gryshko National botanical Garden (NBG) of the National Academy of Sciences of Ukraine, a gene pool of species of the genus Cornus s.l. from various geographical and floristic regions of the world has been created. It includes over 100 taxa (species, cultivars, genotypes, including the little-known rare West-North American endemic Cornus sessilis Torr. ex Durand. In 2018, the species were included in the Red List of Threatened Species of the International Union for Conservation of Nature (IUCN) as a stable condition but it needs constant monitoring due to high population fragmentation and gradual decline of adults. In Ukraine, it is present only in NBG [3-5]. The transferring new species from “in-situ” to “ex-situ” is the main direction of scientific activity of the NBG and the Department of Acclimatization of fruit Plants, in particular. From the point of view of practical value as a fruit, medicinal or ornamental plant, C. sessilis has not yet been sufficiently studied, but it is an endemic with a very limited nature range, so preserving and evaluating its usefulness is an important task for botanists and gardeners. A study was conducted on the adaptation features of Cornus sessilis, blackfruit Cornel, miner's Cornel, introduced into the conditions of forest-steppe zone of Ukraine. The work consisted in assessing the adaptation of C. sessilis bazed on the analyses of bio-ecological features and morphological descriptors of vegetative and generative organs of plants.

California’s endemic Cornus sessilis in Ukraine
(2021) Klymenko, S. V.; Ilyinska, A. P.; Kustovska, A. V.; Melnychenko, N. V.
Global climate change and increased land use lead to the loss of biodiversity at all levels of the organization of living organisms – ecosystems, species, landscape population, genetic, molecular biological levels, etc. The reaction of plants to anthropogenic impact, ac-cording to experts, may be even stronger than postglacial changes. A shift in the thermal isotherm will cause the plants to either move and adapt, or disappear. Endemic species that make up “biodiversity hotspots” require special attention. Cornus sessilis Torr. ex Durand, the object of our research, is part of one of these points – the California Floristic Province. Researchers are now focusing their efforts on de-veloping a climate change – related biodiversity management strategy. In the case of the threat of extinction of the species in nature, there is a important method of preserving it in culture (ex situ). M. M. Gryshko National Botanical Garden at the National Academy of Sciences of Ukraine (the NBG) pays great attention to the introduction of rare endemic species from the different geographical and floristic regions of the world. The gene pool of Cornus L. s. l. in the NBG consists of more than 30 species and 40 cultivars including the insufficiently researched and little-known Californian endemic C. sessilis. In Europe, it has been grown since 2017 only in Chateau Perouse Botanic Gardens (Saint-Gilles, France) and in Ukraine only the NBG has it. In this article we evaluate the life cycle of the development C. sessilis under conditions of introduction different from the conditions of its natural area. To do this, we used the classic traditional methods of the research on the process of introduction, in particular, botanical plant identification, visual observation, phenology, comparative morpholo-gy and biometrics. Morphological descriptors (life form, colour and texture of bark, leaf shape, pubescence character, structure of genera-tive and vegetative buds, inflorescences, flowers, fruits and endocarp) of C. sessilis genotypes introduced to the NBG are identical to those of plants from their natural habitats. The weight of fruits and endocarps were determined by us for the first time. The results of biometric analysis of the size of leaves and fruits showed that the plants of C. sessilis grown in the NBG had the larger leaf blades, but the smaller fruits as compared to those in the wild. In the NBG the plants underwent a full cycle of seasonal development (from the deployment of buds to the leaf fall, inclusive) for 229 days. In general, the phenological strategy of C. sessilis genotypes introduced in the NBG corres-ponds to that of other species of Cornus s. str., including C. mas L. Our results indicate that C. sessilis, California’s rare endemic species new to Ukraine, has adapted to the new conditions – the plants bear fruits and produce seeds. The experience of successful introduction makes it possible to cultivate a new species to expand the diversity of food, medicinal and reclamation plants of the family Cornaceae as well as the use in synthetic breeding to obtain new cultivars with valuable biological and economic properties. Cornus sessilis compatibili-ty test as rootstocks for other species is important for clarifying the theoretical issues of family ties of species Cornaceae and practical – for widespread reproduction of the required cultivars C. mas breeding in the NBG on a potentially compatible rootstock C. sessilis.
Changes in Agrochemical Parameters of Sod-Podzolic Soil Depending on the Productivity of Cereal Grasses of Diﬀerent Ripeness and Methods of Tillage in the Carpathian Region
(2022) Karbivska, Uliana; Asanishvili, Nadiia; Butenko, Andrii; Rozhko, Valentina; Karpenko, Olena; Sykalo, Оksana; Chernega, Tetyana; Masyk, Ihor; Chyrva, Andrii; Kustovska, Alla
Productivity and mowing periods of various cereal grasses on sod–podzolic soil of Pre–Carpathians were studied. The presence of sown grasses with diﬀerent ripeness periods provides uniform supply of mowing mass from the middle of May till late September and productivity of lands, which is 5.4–6.8 t ha-1 of dry mass, exchange energy – 44.1–56.8 GJ ha-1 and 3.81–4.87 t ha-1 f.u. On the basis of the obtained results, it was found that with increase of tillage depth from 8–10 cm for surface tillage with disk tools to 20–22 cm by plowing, the productivity of all studied species increased by 2–3% on average for three years with fertilization dose of LSD05 equal to 0.30 t ha-1. Cultivation of cereal grasses on sod–podzolic soils stipulates improvement of their fertility, in particular increasing indices of nitrogen, phosphorus and potassium.
Chenopodium album L. в агроценозах Лівобережного Лісостепу Київщини
(Полтава : Видавництво ПП "Астрая", 2024-11-22) Пінчук, О. О.; Кустовська, Алла Валентинівна
Chenopodium album має значний лікарський потенціал, завдяки своїм антиоксидантним, протизапальним та очищувальним властивостям. Вона широко розповсюджена на території Лівобережної Лісостепової зони Київщини, зокрема на полях Яготинської громади. Завдяки своїй пластичності до кліматичних умов лобода біла активно заселяє занедбані поля, пустирі, узбіччя доріг та інші місця, де відсутня активна обробка ґрунту. Рослинну сировину лободи білої можна використовувати як джерело корисних речовин для народної та традиційної медицини, але необхідні додаткові дослідження біологічних особливостей та біохімічного складу з метою отримання безпечних лікарських засобів. Водночас, враховуючи, що лобода біла є бур’яном, слід забезпечувати комплексний підхід з обмеженням її поширення в агроценозах, де вона може конкурувати з культурними рослинами за ресурси.

Comparison Between Balloon Angioplasty and Surgical treatment for Native Coarctation of the Aorta in Infants
(2018) Truba, Y.; Dzuriy, I.; Diachenko, V.; Plyska, O.; Imanov, E.; Lazoryshynetz, V.
Coarctation of the aorta (CoA) is a discrete stenosis of the proximal thoracic aorta. The common clinical pattern is congestive heart failure in infancy. Treatment methods include balloon angioplasty (BA) and surgical repair in this age group. Percutaneous balloon angioplasty is a less invasive method for the repair of discrete coarctation but remains controversial as a primary treatment strategy for a native coarctation. This study aimed to compare the effectiveness and outcome of balloon angioplasty and surgical repair in infants with coarctation of the aorta younger than one year old. Methods. Between January 2011 and December 2017, 59 patients with native aortic coarctation were treated in National Amosov Institute of Cardiovascular Surgery. This retrospective study evaluated the results of the two methods in patients younger than one year old with the diagnosis of coarctation of the aorta. Group 1 included 18 patients who accepted balloon dilatation for discrete coarctation. Group 2 included 41 patients who underwent surgical resection with end-to-end anastomosis. Patients with complex cardiac anomalies were not included in this study. Results. Immediate results revealed no significant difference in the effectiveness of the two methods (p value =0.06). While the rate of recurrent coarctation was significantly lower in the surgery group [1 (2,4%) vs. 13 (72,2%), p value =0.0017]. The mean hospital stay was 6.4±3.6 days in the balloon angioplasty group and 21.5±8.7 days in the surgery group, which constitutes a significant statistical difference (p value <0.05). Aneurysm formation was not encountered. Conclusion. Both surgical repair and balloon angioplasty for native coarctation of the aorta in infants were effective and beneficial. These data suggest that balloon angioplasty can be acceptable alternative to surgical treatment but due to the high level of recoarctation this method may be considered in critically ill infants with congestive heart failure as a primary palliative procedure. The limitations of this study were its retrospective, nonrandomized nature, and smaller case numbers.

Cornus mas nanocomposites with inorganic carriers: study of adsorption and bioactive substance release
(Національний медичний університет імені О. О. Богомольця, 2025-01-28) Kustovska, A.; Skwarek, E.; Kowalska, K.; Paientko, V.; Demianenko, E.; Matkovsky, A.; Gun’ko, V.; Klymenko, S.; Vedmedenko, V.
Obtained by the method of mechanochemical activation of a nanocomposite based on the fruits of Cornus mas L. (yellow and red varieties) and inorganic components. The use of mechanochemical activation contributes to increasing the bioavailability of bioactive substances (BAS). At the present stage, science is focused on creating innovative materials to increase the efficiency and availability of natural compounds. A promising direction is the use of nanocomposites based on plant raw materials enriched with bioactive substances (BAS) that have high bioavailability and stability. Dogwood fruits (Cornus mas L.) are a source of cyanide-3,5-diglycoside with antioxidant properties, but their extraction is complicated by strong bonds with cell wall biopolymers. Mechanochemical activation, which combines grinding of raw materials with inorganic carriers (clay, diatomite, silica), is a promising technology. Inorganic components destroy membranes, stabilize BAS molecules and increase their sorption properties. The work studies the interaction of plant raw materials and inorganic carriers to create effective nanocomposites, as well as the effect of mechanochemical activation on the properties of materials.
