Authors: Серёдкин И.В. , Сутырина С.В. , Микелл Д.Дж. 
Published: December 2024

На Среднем Сихотэ-Алине (Дальний Восток России) евразийская рысь (Lynx lynx) находится на востоке своего обширного ареала в Евразии. Методические ограничения в исследованиях обусловили недостаточную изученность пространственной экологии рыси в регионе, знания которой востребованы для управления популяцией. Впервые для Азии и России с использованием метода радиотелеметрии определены характеристики суточных перемещений пяти самцов евразийской рыси, обитавших в 2001–2018 гг. в Сихотэ-Алинском биосферном заповеднике и его окрестностях. Суточные смещения рысей без учета сезона составили в среднем 2.46 км (стандартное отклонение = 2.72 км) при максимальном значении 19.2 км. Отдельно для каждого из самцов средние суточные смещения оценены в 2.15; 1.96; 2.49; 3.66; и 1.94 км. Суточные смещения рысей были достоверно больше в снежный сезон по сравнению с бесснежным (в среднем 2.65 и 2.32 км соответственно). В брачный период (февраль–март) среднее суточное смещение самцов составило 2.95 км, что превосходило данный показатель, рассчитанный для всего остального времени года (2.28 км). Суточное смещение не учитывает извилистость пути животного, поэтому меньше истинного суточного хода. Исследование вносит вклад в изучение пространственной экологии евразийской рыси.
In the Middle Sikhote-Alin (Russian Far East), the Eurasian lynx (Lynx lynx) is found in the east of its extensive area in Eurasia. Methodological limitations in research have led to insufficient knowledge of the spatial ecology of lynx in the region, knowledge of which is in demand in population management. For the first time in Asia and Russia, using the radiotelemetry method, the characteristics of the daily movements of five male Eurasian lynx that lived in the Sikhote-Alin Biosphere Reserve and its environs from 2001 to 2018 were determined. Daily displacements of lynxes without taking into account the season averaged 2.46 km (SD = 2.72 km) with a maximum value of 19.25 km. Separately for each of the males, the average daily displacements were estimated at 2.15, 1.96, 2.49, 3.66 and 1.94 km. The daily displacements of lynxes were significantly greater in the snowy season compared to the snowless season (on average 2.65 and 2.32 km, respectively). During the mating season (February-March), the average daily displacement of males was 2.95 km and exceeded this figure calculated for the rest of the year (2.28 km). The daily displacement does not take into account the tortuosity of the animal’s path, and is therefore less than the true daily movement. The study contributes to the understanding of the spatial ecology of the Eurasian lynx.
Productivity and basic indicators of common bean (haricot) modern varieties suitability for mechanized harvesting
Authors: Olifirovych S. 
Published: December 2024

Goal. Investigation of plants height, a lower bean attachment height, 1000 seeds weight, ripening period duration, and productivity of common bean (haricot) modern varieties, depending on cultivating technological methods.
Methods. Field method — to determine the plants height and grain crop capacity; laboratory one — to determine the basic elements of common bean plant crop structure; statistical — for mathematical data processing by variance analysis method.
Results. All the six common (haricot) bean varieties investigated in the research, were bushy. However, the varieties Nata and Bukovynka showed the «chick-pea» (twisted) top appearance in years with excessive humidity. The variety Slavia was characterized by the lowest height of the lower bean attachment — 8.1—8.8 cm. Other researched varieties were more technologic. Particularly, the variety Galaktyka had the lower bean attachment height 10.1—10.6 cm, Bukovynka — 10.5—11.5, Nata — 10.5—11.8, Ros’ — 11.4—12.4 cm. The lower bean elevated location of the variety Otrada (12.9—13.5 cm) allows to minimize the losses during direct combine harvesting. All the varieties investigated by us had a medium-sized seed (from 201 tо 400 g). The smallest seed was in the variety Bukovynka — 204—212.6 g. The largest 1000 seeds weight was in the variety Galaktyka — 323.5—337.9 g. All the common bean vaieties researched in the experiment, except Galaktyka, exceeded the variety Bukovynka by grain yield. Thus, on the variant without seed inoculation and using potassium humate, the variety Galaktyka grain yield made 1.33 t/hа, which was by 34.5% less, compared to the variety Bukovynka. A complex use of inoculants and potassium humate provided a significant grain yield increase of the researched common bean varieties. The maximum yield increase in the research (0.27 t/hа or 11.0%) was obtained during pre-sowing seed inoculation and two foliar feedings with potassium humate of common bean stands of the variety Otrada.
Conclusions. All the varieties researched in the experiment are bushy, and bushy with a «chick-pea» (twisted) top and suitable for direct combine harvesting. The maximum grain yield level was provided by the following varieties: Otrada — 2.72 t/ hа; Nata — 2.65 t/hа, and Ros’ — 2.54 t/hа, during seed inoculation with biologics Rhizoactive + Rootella, complete mineral fertilizer introduction in dosage N32Р32К32, and two foliar feedings with potassium humate.

Published: December 2024

Goal. To determine the species composition of pathogens of potato fungal diseases in the western region of the forest-steppe zone under climatic changes.
Methods. Research was conducted during 2021—2022 on the basis of the Ukrainian Plant Quarantine Research Station of the Institute of Plant Protection using laboratory (identification of pathogens) and field (examination of potato plantations and analysis of tuber material) methods.
Results. According to the research results, the most common fungal diseases on vegetative plants during the studied period were: anthracnose (Colletotrichum coccodes (Wallr.) S. Hughes), Alternaria solani (Ellis & G. Martin) L.R. Jones & Grout, Alternaria alternata (Fr.) Keissl.), fusarium wilt (Fusarium oxysporum Sсhl.) and late blight (Phytophthora infestans (Mont.) de Bary). As a result of phytopathological analysis of tubers, it was established that the greatest danger during potato storage is caused by pathogens of the genera Fusarium, Phoma, Colletotrichum, Phytophthora, causing fusarium, fomosis, anthracnose, phytophthora and mixed types of rot. the causative agents of fusarium were identified — Fusarium oxysporum Sсhl., F. sambucinum Fuck., F. solani Vart.; phomoza — Rhoma exigua Desm. var. exigua rhizoctonia — Rhizoctonia solani (J. G. Kühn) [teleomorph Thanatephorus cucumeris (A. B. Frank) Donk]; Alternaria solani (Ellis & G. Martin) L.R. Jones & Grout; Alternaria alternata (Fr.) Keissl.; anthracnose — Colletotrichum coccodes (Wallr.) S. Hughes, late blight — Phytophthora infestans (Mont.) de Bary); the share of fusarium was 42.1%, the causative agent of anthracnose — 27.5%.
Conclusions. Fungal diseases (anthracnose, fusarium wilt) of potatoes, which at the end of the twentieth century were considered to be of limited distribution, have become widespread, which requires their further study in order to optimize crop protection.

Authors: Semenchuk V. , Kharabara V. 
Published: December 2024

Goal. To establish the effect of a multicomponent preparation of biologic origin on seed potato productivity and viral diseases infestation in condition of southwestern Forest Steppe of Ukraine.
Methods. Field method — the trial plots were set in selection-seed production rotation of Bukovinian state agricultural research station of Carpathian region Institute of agriculture NAAS. Laboratory-field method — determining crop capacity and tubers structure in a yield. Visual method — plants infestation assessment. Comparative-calculated method — to determine the potato stands productivity and viral diseases infestation degree.
Results. Avatar-2 Zahyst is a system-contact preparation of virulicidal, fungicidal, and antibacterial action. It is recommended for use on grain, technical, vegetable-, and fruit crops. The preparation is used for pre-sowing seed treatment, as well as for vegetating plants treatment. When determining the seed potato productivity depending on the biopreparation Avatar-2 Zahyst implementation, no significant difference in tubers yield was established; on the variety Slauta it stayed within 34.5—36.3 t/ hа, and on the variety Kimmeria 36.7—37.4 t/ hа. No any significant difference was established also in quantity and tubers mass per one bush, as well as in one tuber average mass, and tubers fractional composition in a harvest. When determining plants infestation with viral diseases, it was established, that the biopreparation Avatar 2 Zahyst application has influenced the decrease of seed potato stands infestation. The variety Slauta damage on the variant with seed poisoning and three-times spraying during vegetation made 2.5%, which is by 2—3% lower than on the control variant. The infestation of plants where only seed poisoning was implemented made 3—4%, when of those where three-times preparation application was carried out during vegetation — 2.0—4.0%, which is by 0.5—2.5 and 1.5—2.5% lower than the control variant, respectively. The same tendency was observed during the variety Kimmeria investigation.
Conclusions. The use of the biological product Avatar-2 Zahyst does not give a significant difference in the yield of tubers. The introduction of the biological product Avatar 2 Zahyst influenced the reduction of the incidence of viral diseases in potato seed plantations.

Authors: Chervyakova L. , Panchenko T. , Tsurkan O. 
Published: December 2024

Goal. Development of a method of analytical control of glyphosate in preparative forms of herbicides.
Methods. Determination of glyphosate was carried out by the chromatographic method of thin-layer chromatography (TLC) using Sorbfil plates with a thin layer of silica gel KSK adsorbent. The active substance was identified by the value of Rf, quantitative determination was based on the formalized dependence of the size of the area of the chromatographic zones on the amount of glyphosate.
Results. Physicochemical properties of herbicides — electrolytes, to which glyphosate belongs, create special problems when developing methods for its determination in various matrices. In herbicides and desiccants, glyphosate (as a salt) usually takes the form of a deprotonated acid residue and a corresponding cation. Therefore, the determination of the active substance is carried out by the acid residue, which is important for the quantitative assessment of its content in the matrix both in the acid equivalent and in the form of the corresponding salt. The density of the preparative form serves, in particular, as a criterion for controlling the form of the glyphosate salt. The method is based on dissolution of the preparation form in 44% ethanol and quantitative determination by TLC method. The determination of the active substance is not hindered by other components of the preparations, derivatives of glycine and amines.The optimal conditions of analysis were chosen using the conceptual designs of the laboratory «Algorithm of chemical-analytical monitoring of pesticides» and «System of multi-quantitative determination of pesticides in matrices», according to which the main stages of the process are extraction/dissolution, purification of extracts, elution (chromatographic process), identification and quantitative analysis . Selective conditions for TLC determination — mobile phase with pH 9: distilled water + ethanol + aqueous ammonia (22 + 20 + 0.25 by volume), developing reagent: a specific complex of ninhydrin with cadmium acetate in an acidic medium. Quantitative determination is carried out taking into account the coefficients of conversion of the corresponding salt form to the acid equivalent.
Conclusions. The use of the chromatographic method of thin-layer chromatography makes it possible to control the content of the active substance glyphosate in various salt formulations in preparative forms of herbicides and desiccants with high accuracy and reproducibility.

Authors: Hrytsiuk N. 
Published: December 2024

Goal. The study of the varieties of domestic and foreign selection of winter wheat for resistance to the main pathogens of root rot (Fusarium graminearum and Bipolaris sorokiniana) and the determination of their harmfulness.
Methods. Laboratory method — for the isolation of pathogens in pure culture, for artificial infection with pathogens of root rot, for the determination of growth parameters of winter wheat; dispersive, statistical and regressive methods for the reliability of the obtained results.
Results. The agressiveness and the virulence of the main causative agents of winter wheat root rot under artificial seed infection have been established. The assessment of the resistance of winter wheat varieties to Fusarium and Helminthosporium root rot was carried out, the development of the disease in relatively resistant varieties ranged from 0.1 to 0.9 points, the spread was 10.0—45.5%; the development of weak–resistant varieties was 1.0—1.2 points, prevalence of 40.9—50.0%; the developmen tof susceptible varieties was 1.7—2.23 points, spreading — 71.8—94.0%. The harmfulness of Fesarium graminearum and Bipolaris sorokiniana on seedling and root length was studied. In susceptible to Fusarium rot varieties of Novosmuglianka, Poliska 90, Lisova Pisnia, the seedling length was reduced by 5.7—6.9 cm, the root length was reduced by 2.51—3.21 cm compared to relatively resistant Samurai varieties.
Conclusions. The most common types of root rot in Zhytomyr region are Fusarium and Helminthosporous root rot. No root rot resistant varieties of winter wheat were found among the research varieties, but relatively resistant and weak-resistant varieties were selected. For sowing on agricultural enterprises, relatively resistant to Fusarium graminearum and Bipolaris sorokiniana varieties of Samurai, Kraievyd, Podolianka, Scagen can be recommended. Weak-resistant to Fusariosis can be recommended Bohemia, Podarunok Podillia varieties and weak-resistant to helminth sporiasis can be recommended Poliska 90. In protection of winter wheat crops from harmful organisms, the correct selection of varieties plays a special role, therefore, when developing the integrated protection technology, special attention should be paid to the varieties that show resistance to certain diseases and types of pathogens.

Authors: Sinaga Joshua Princeman , Sinaga Bintang Yinke Magdalena , Siagian Parluhutan , Eyanoer Putri Chairani , Samodra Yoseph Leonardo 
Published: December 2024

Background:Post-COVID Syndrome (PCS) is a newly recognized condition reported by approximately 45% of individuals following COVID-19 infection. This syndrome is estimated to affect the health-related quality of life in 10–30% of affected individuals.
Objective:To examine the characteristics of Post-COVID Syndrome among healthcare workers at Adam Malik Hospital.
Methods:This study employed a cross-sectional descriptive design. Data were collected using structured questionnaires administered to healthcare workers at Adam Malik Hospital who had contracted COVID-19 between 2020 and 2022.
Results:A total of 120 participants were included in the study. The sample was predominantly female (78.3%), with the youngest age group (19–30 years) comprising 37.5% of participants. Most participants had direct exposure to patient care (78.3%) and were confirmed COVID-19 positive in 2021 (42.5%). Notably, 45.0% of participants were unvaccinated, 20.9% had a history of hospitalization, and 78.3% experienced mild COVID-19 infections. Hypertension was identified as the most common comorbidity. Participants were categorized as experiencing Acute PCS (43.9%) or Chronic PCS (56.1%), with both groups exhibiting similar predominant symptoms, including fatigue, persistent cough, memory impairment, and cognitive difficulties. Statistically significant associations were identified between PCS and variables such as sex (p=0.004, OR=0.27), age (p=0.015, OR=4.46), severity of prior COVID-19 infection (p=0.040, OR=1.77), vaccination status (p<0.001, OR=3.82), and the presence of comorbidities (p=0.025, OR=2.53).
Conclusion:Post-COVID Syndrome is characterized by multifactorial etiologies and heterogeneous clinical manifestations. Factors such as gender, age, vaccination status, comorbid conditions, and severity of prior infections were significantly associated with PCS outcomes. Gender-related differences, potentially influenced by immune response, hormonal mechanisms, and antibody production, appear to contribute to variations in PCS manifestations. These findings underscore the need for further research to elucidate the epidemiology, clinical presentations, and pathological mechanisms underlying this emerging post-viral condition.

Voices from Rural Thailand: Understanding the Root Causes of Adolescent Pregnancy
Authors: Panjarut Laisuwannachart , Chamroonsawasdi Kanittha , Vatanasomboon Paranee , Kittipichai Wirin 
Published: December 2024

Background: Adolescent pregnancy is an important global health concern. Almost 21 million adolescent women between the ages of 15 and 19 in developing countries become pregnant, and approximately 12 million of them give birth annually. Adolescent pregnancy has consequences for the health, social, and economic outcomes of adolescent women, their babies, and their families. Those in rural areas are particularly vulnerable due to poverty, inadequate education, limited access to contraception, and traditional beliefs.

Objective:This qualitative study aims to explore the root causes of adolescent pregnancy in rural Thailand.

Methods: This qualitative study was conducted from August to September 2023. We collected data through in-depth interviews with three mother-daughter dyads, whose daughters experienced adolescent pregnancy, and focus group discussions among four healthcare providers and four school teachers. We transcribed the data verbatim and applied thematic analysis.
Results: The findings showed that the root causes of adolescent pregnancy include: 1) inadequate problem-solving skills to prevent adolescent pregnancy; 2) ineffective sexual communication; 3) poor family relationships; and 4) poor behavior control to prevent adolescent pregnancy.

Conclusion:Our findings reveal the root causes of adolescent pregnancy in rural Thailand. Understanding these factors allows us to better address the unique challenges faced by adolescents in these communities. We should focus on these factors to design tailored interventions and involve multilevel stakeholders, including family, school, and healthcare services to prevent adolescent pregnancy.
