Propõe-se uma sequência didática no formato de Unidade de Ensino Potencialmente Significativa (UEPS) para o ensino de cinemática relativística, baseado no livro An illustrated guide to relativity, Takeuchi (2010). As aulas estão distribuídas pelos seguintes tópicos: estudo sobre referencial, estudo sobre velocidade relativa, estudo sobre velocidade relativa no diagrama espaço-tempo, estudo sobre a velocidade da luz, estudo sobre velocidade relativa relativística no diagrama espaço-tempo, estudo sobre causalidade no diagrama espaço-tempo, estudo sobre sincronização dos relógios no diagrama espaço-tempo, estudo sobre dilatação dos relógios no diagrama espaço-tempo e estudo sobre contração de Lorentz. A sequência prevê uma aula para resoluções de problemas quantitativos e outra aula para questões qualitativas, que utilizará a metodologia ativa, instruções por colegas, peer instruction, para obter uma consolidação da aprendizagem. Espera-se que na UEPS, a cinemática clássica de Galileu facilite o atendimento da cinemática relativística e que o peer instruction facilite a aprendizagem através das interações entre colegas.
Atividades experimentais semiabertas com brinquedos como forma de falseamento de modelos teóricos ideais: conservação de energia mecânica?
Authors: Moreira Augusto , Neto G. C. , Farias D. R.
Published: June 2024

Neste trabalho, propomos um exemplar metodológico formado por um experimento de baixo custo e lúdico, para se estudar modelos teóricos envolvendo conservação de energia. O experimento, por não conservar energia, permite não apenas trazer à tona as limitações do modelo teórico estudado no início dos manuais didáticos, como também inserir os estudantes em práticas experimentais abertas e, portanto, mais próximas de uma prática científica. Uma vez que pretendemos inserir laboratórios abertos em situações problematizadoras análogas a práticas científicas, adotamos como referencial teórico os programas de pesquisa de Lakatos dado que este último preserva a teoria geral em um núcleo irredutível, levando toda e qualquer anomalia a ser questionada/discutida apenas no cinturão protetor.

Patients with critical illnesses are frequently need mechanical ventilation as part of their care, in addition to or instead of spontaneous breathing. In certain situation, poor CO2 elimination (ventilation failure) is the primary issue. Malnutrition is one of the issues that can occur in patients on mechanical ventilation. Patients in critical condition are typically incapable of consuming enough food to meet their metabolic needs. Enteral nutrition, parenteral nutrition, or mix of two are able to provide nutritional intake. Enteral nutrition can help maintain the intestinal wall's functional integrity by protecting intraepithelial cells, increasing blood flow, and encouraging the production of endogenous trophic agents. In the meantime, parenteral nutrition (PN) must be administered if the patient's nutritional needs are not satisfied within three days, as malnutrition typically develops eight to twelve days following surgery and/or ICU admission. Numerous studies comparing the effects of (enteral nutrition) versus PN nutrition on ICU LOS and mechanical ventilation have found no discernible differences between the two. When comparing EN to PN nutrition, there is a noticeable difference in how well EN reduces infectious complications.

Published: June 2024

This literature review delves into the impact of regular physical activity on lipid profiles and cardiovascular health in adolescents, addressing the growing concern of sedentary lifestyles and unhealthy habits contributing to increased cardiovascular disease risks among teenagers. By systematically searching academic databases and scientific journals using relevant keywords, a selection of 8 articles was chosen for review after rigorous screening and eligibility assessment. The findings of the review underscore the significant relationship between physical activity, metabolic parameters, and cardiovascular risk factors in adolescents. Studies consistently highlight the benefits of regular physical activity in improving lipid profiles, insulin sensitivity, and overall cardiovascular parameters in this population. For instance, adolescents engaging in moderate to high-intensity physical activity demonstrated reduced risks of metabolic syndrome and improved insulin sensitivity. Lifestyle modifications encompassing increased physical activity and dietary changes were associated with positive alterations in lipid and glycemic profiles, particularly in high-risk pediatric individuals. Notably, regular vigorous-intensity physical activity was found to yield favorable cardiometabolic outcomes in adolescents with type 2 diabetes. In conclusion, the review emphasizes the critical role of regular physical activity in maintaining cardiovascular health and managing metabolic risk factors among adolescents. Participation in physical activity, particularly at moderate to high intensity, holds promise for significant improvements in lipid profiles and cardiovascular parameters. These findings underscore the importance of promoting active lifestyles among teenagers to prevent cardiovascular disease and enhance overall health outcomes.

The aim. The research was conducted to assess the total antioxidant and glutathione status, superoxide dismutase activity in menopausal women with moderate and asymptomatic COVID-19.

Materials and methods. Ninety two women 45 to 69 years old were divided into groups: women without COVID-19, not vaccinated, with no antibodies to SARS-CoV-2 (IgG) – control; women with moderate COVID-19 – main group; women with anti-SARS-CoV-2 IgG in blood but who deny any symptoms of COVID-19 in the last 12 months – asymptomatic COVID-19.

Results. A lower glutathione peroxidase (GPx), superoxide dismutase (SOD) activities and a higher glutathione reductase (GR) activity, glutathione S-transferase pi (GSTpi) concentrations were detected in the patients with moderate COVID-19 as compared to control. There were statistically lower oxidized glutathione (GSSG) levels, total antioxidant status (TAS) and higher reduced glutathione (GSH) levels, as well as GSH/GSSG ratio in the group with asymptomatic COVID-19 as compared to control. Significantly a lower GPx, SOD activities and a higher TAS, GR activity, GSTpi concentrations were detected in the patients with symptomatic COVID-19 as compared to group without clinical symptoms. ROC analysis shows the diagnostic significance of TAS (AUC = 0.714; p = 0.048), GSH (AUC = 0.714; p = 0.030), GSSG (AUC = 0.712; p = 0.031), GSH/GSSG (AUC = 0.837; p < 0.001) for group with asymptomatic COVID-19 compared with controls; TAS (AUC = 0.709; p = 0.020), SOD (AUC = 0.760; p < 0.001), GSH/GSSG (AUC = 0.658; p = 0.039), GPx (AUC = 0.774; p < 0.001), GSTpi (AUC = 0.864; p < 0.001) and GR (AUC = 0.871; p < 0.001) for group with moderate COVID-19 compared asympotmatic COVID-19.

Conclusions. Antioxidant defense system activity in menopausal women depends on the COVID-19 course.

Authors: Taskina E. S. , Solovyova A. A. , Mudrov V. A. , Kharintseva S. V.
Published: June 2024

The prevalence rate of dry eye syndrome varies from 6.5 to 95 %. Diagnostic criteria are based on different methods and/or their combinations and are characterized by heterogeneity.

The aim of the study. To identify the risk factors for the development of dry eye syndrome in order to create a technology for early diagnosis of the degree of the disease in young people without concomitant ocular and general somatic pathology.

Materials and methods. Fifty patients aged 24 [22; 27] years were examined. We carried out an ophthalmological examination, including autorefractometry, visometry, biomicroscopy, the Norn test, a survey using the author’s questionnaire, and an assessment of the degree of dry eye syndrome using the Ocular Surface Disease Index (OSDI). Three study groups were formed: control group (OSDI = 0–13 points); group 1 – patients with OSDI = 14–22 points; group 2 – patients with OSDI > 22 points.

Results. When examining presented independent variables, screen time had the highest normalized importance (100 %), followed by tear film breakup time (58.4 %), smoking (24.3 %), night shifts (22.5 %) and using soft contact lenses (11.1 %). The technology for early diagnosis of the degree of dry eye syndrome is implemented on the basis of a multilayer perceptron, the percentage of incorrect predictions during its training process was 8.0 %. The structure of the trained neural network included 8 input neurons (the value of screen time and tear film breakup time, the presence or absence of smoking, night shifts and/or the use of soft contact lenses), two hidden layers containing 3 and 2 units, respectively, and 3 output neurons.

Conclusion. The proposed neural network has no difficulties in assessing the early diagnosis of the severity of dry eye syndrome and can be used in clinical practice.

Published: June 2024

Granulomatosis with polyangiitis (GPA) is manifested as ocular pathology in almost a third of patients, which can either be detected at the onset of the disease or occur in the late stages. The pathological process involves the orbit, sclera, episclera, cornea, conjunctiva, eyelids, nasolacrimal system, optic nerve, retina and choroid. Lesion of eye and its surrounding structures determines the severity of the pathological process, the patient’s quality of life and prognosis. The article presents a clinical case of a 38-year-old man with an unfavorable course of GPA, lesion to upper and lower respiratory tract, kidneys, and musculoskeletal system. The authors consider ocular manifestations in the context of a systemic disease. An ophthalmological examination of the patient revealed changes in sclera and choroid, which had not previously been described in detail in the literature. The patient underwent cataract phacoemulsification in the right eye with implantation of a posterior chamber intraocular lens. The dynamics of clinical manifestations of eye lesion in the near future is positive, but in the long term it remains doubtful due to pronounced changes in the orbit and adnexa of the eye against the background of ongoing small vessels vasculitis. Early consultation with an ophthalmologist and optical coherence tomography in patients with GPA are necessary at any stage of the disease. The clinical case is presented with consideration to the CARE 2021 recommendations.

Authors: Makhmutov R. F. , Poshekhonova J. V. , Likhobabina O. A.
Published: June 2024

Background. In recent years, modern medicine has been paying increasing attention to the patient’s quality of life, both in an interdisciplinary approach and in individual diseases. Quality of life is not only an important component of overall health, but also allows the clinician to develop an individualized approach to the patient based on general criteria for the pathological condition.

The aim of the work. To assess the quality of life of a child with post-COVID syndrome.

Material and methods. We studied the tonus of autonomic nervous system, the level of memorization, attention span and performance distribution, work efficiency, mental stability, and self-assessment of the anxiety level. The quality of life was assessed using our own method “Quality of life of children with post-COVID syndrome”. Results. A child with post-COVID syndrome developed vegetative, psycho-emotional, and cognitive disorders, which caused significant discomfort in everyday life and persisted for a long period. The neurovegetative changes described above were functional in nature, which allows us to hope for their reversibility. After the treatment, the teenager’s quality of life, based on assessment using our methodology, had a satisfactory score (43 points).

Conclusion. The clinical case was characterized by asthenoneurotic disorders, autonomic disorders, increased anxiety, emotional lability, and some cognitive impairments that negatively affected the patient’s quality of life. The above describes the growing need for further development of assessment of the quality of life of children with post-COVID syndrome in order to form clear personalized algorithms for medical correction and rehabilitation of such patients.

Published: June 2024

Anthrax remains relevant in the world and in the Russian Federation. In Siberia and the Far East, epizootological, epidemiological, environmental and microbiological monitoring of anthrax is constantly carried out. To analyze the epizootological and epidemiological situation of anthrax, we used the information from veterinary institutions and Rospotrebnadzor for 24 regions, as well as reference and archive materials. On the territory of Siberia and the Far East for the period from 1985 to 2023, pronounced epizootological and epidemiological problems of anthrax are observed in the Yamalo-Nenets Autonomous Okrug, the Republic of Buryatia, Omsk Region and the Altai Territory. Over the last five-year observation period, high epizootic activity has been observed in the west of the Republic of Tyva. A total of 3,375 livestock animals and 128 people fell ill. The anthrax database contains information on 7,491 stationary anthrax-infected points in 22 subjects and 562 anthrax burials and cattle burials in 17 subjects of Siberia and the Far East. B. anthracis strains have slight variability in biological properties and belong to two global genetic lines – A and B. In order to prevent anthrax, it is necessary to ensure surveillance of soil foci of anthrax (anthrax burials and cattle burials, “plague fields”), a high level of livestock animals registration and their specific vaccination coverage; to control the implementation of veterinary and sanitary requirements for pre-mortem inspection and emergency slaughter of livestock, the sale of meat and meat products, and biological waste disposal; to carry out explanatory work among the population.

The aim of this article was to show the labor valour during the Great Patriotic War of the employees of the first research institute in Irkutsk, which began its history in 1912, as well as their success of the present time. The oldest scientific institution in the Irkutsk region was originally created on the initiative of the Siberian Medical Society as a laboratory and was transformed into the Chemical and Bacteriological Institute in 1918, and in 1930 it became the Institute of Epidemiology and Microbiology of the People’s Commissariat of Public Health of Russia.

By the beginning of the Great Patriotic War, the institute had an epidemiological department and a microbiological laboratory that carried out epidemiological surveillance and diagnosis of a wide range of infections in Siberia. During the war years, the manufacturing sector with the production of vaccines and serums acquired particular importance. By the end of the war, 285 employees worked at the institute, 32 of them had higher education. During the war years, the production of vaccines against typhoid, paratyphoid, dysentery, diphtheria, tuberculosis, and smallpox was significantly increased. Serums against tetanus and measles, and a dysentery bacteriophage were produced. At the same time, research projects and thesis works were carried out. The employees of the institute received national and departmental awards, commendations, honorary distinctions, and rewards for their scientific work and production excellence.

Currently, the institute continues the glorious traditions of the past and demonstrates truly heroic efforts in the development of virology and microbiology, working in priority areas of medical and biological science. Of course, the works of scientists of the present time will be appreciated only by descendants, as is now happening with the assessment of the work of the Institute of Epidemiology and Microbiology during the Great Patriotic War.

Authors: Ukhanova A. V. , Poskotinova L. V.
Published: June 2024

Background. The impact of natural and climatic factors on human health may change under the influence of other factors related to his socio-economic well-being. The aim of the study. To determine the correlation between indicators of heart rate variability and parameters of socio-economic well-being, quality of life of young people living in the Arctic zone of the Russian Federation (Arkhangelsk).

Materials and methods. Parameters of Heart rate variability in 36 young men (16–18 years old) were determined at entry (5 minutes) and at a fixed breath rate (5 minutes). We used the World Health Organization Quality of Life Brief Version of questionnaire, Family Affluence Scale (FAS II) and a questionnaire reflecting the financial situation, composition, and large number of children in the participants’ families.

Results. According to correlation analysis, a decrease in the number of family vacations per year and FAS-II scores is accompanied by an increase in sympathetic activity. Indicators of self-perceived health status, number of cars in the family, FAS-II score and family financial status are positively correlated with indicators of vagal activity. Parameters of the psychological sphere of life quality and family composition were negatively correlated with sympathetic activity; parameters of the physical sphere of life quality and the number of family vacations per year were negatively correlated with vagal activity (fixed breath rate).

Conclusion. We identified specific indicators of socio-economic well-being that are most closely related to both the tension of the cardiac activity mechanisms and the decrease in vagal reserves of autonomic regulation in young men living in the Russian Arctic.
Convective Phenomenes in the Context of Meso-β-scale Convective Structures
Authors: E.M. Livshits , V.I. Petrov
Published: June 2024

This review article presents the results of radar studies of convective phenomena in Moldavia and the North Caucasus using Eulerian (ECS) and Lagrangian (LCS) coordinate systems. Application of the Lagrangian approach allowed us to exclude the influence of the tropospheric displacement and to obtain integral grid patterns of thunderstorm-hail processes. These structures are especially well manifested at small wind shears (up to 1 m/sec/km). At large shears, the mesh structures are transformed predominantly into linear structures. The methodology for obtaining integral pictures of radio echoes of thunderstorm processes is described. Intersections of linear elements, which we call faces, occur at nodes. The latter plays a particularly important role in the dynamics and kinematics of convective storms. The latter play a particularly important role in the dynamics and kinematics of convective storms. The development of storms occurs along the facets and at the nodes of meso-β-scale convective structures (MMCS), which explains the mechanisms of splitting and merging of storms: in the first case the facets diverge, in the second case they converge. The relations of motion vectors for different types of storms are obtained. It is shown that the direction of the radio echo canopy coincides with the storm motion trajectory; the evolution vector (propagation) for the most powerful storms deviates from the storm displacement direction by 80°–135°. The structure of the updated band within which the Flanking Line is formed for supercells and multicells is studied. Mnemonic rules have been derived that allow one to infer from instantaneous patterns of anvil orientation and the mutual location of storms whether they are converging or diverging, and to identify left- or right-moving storms. A hypothesis on the internal structure of the cold front of the 2nd kind is stated. The main conclusion of the work is that the evolution of storms is determined by the configuration of meso-β-scale convective structures. This explains various convective phenomena from unified positions. The results are applicable in works on modification of convective cloudiness, for ultra-short-term forecasts of dangerous phenomena, storm warnings of the population, rescue services, etc.

Tenotomy and tenodesis of the biceps are the surgical techniques used to treat pathology of the long biceps. Between the proponents of the two techniques, the superiority of one over the other is still debated. The Popeye sign is often cited to the disadvantage of tenotomy. The aim of our study is to report on our experience using a self-locking tenotomy and its impact on Popeye's sign, and to assess our functional results. This is a retrospective study of 53 shoulders treated for long biceps tendinopathy, isolated or associated with a rotator cuff tear. All patients underwent surgery at the AILE 4 orthopedic department of the Ibn Rochd University Hospital in Casablanca over a period of five years, and were reviewed at least six months later. A self-locking tenotomy was performed in all patients. The mean age at surgery was 58 years. Popeye's sign was observed in five patients and was well accepted in four patients. Constant-Murray scores improved significantly by an average of 25 points. Satisfaction was over 90%. Professional and sporting activities were resumed in all patients. We highlight the value of the self-locking tenotomy as a simple, rapid, reproducible, effective and low-cost arthroscopic technique, ensuring a tenodesis effect by reducing the rate of appearance of Popeye's sign.

Introduction: Shoulder dislocations, common in emergency departments, often include anterior dislocations. Bilateral dislocations, particularly posterior, are rare and are generally caused by sporting accidents or convulsions. Bilateral anterior dislocations are even rarer and often of traumatic origin. Case report: We analyzed three new cases of bilateral anterior shoulder dislocation, examining the mechanisms, risks and treatments Discussion: Bilateral dislocation, often posterior but sometimes anterior, is rare and can result from high-energy trauma or convulsions. A careful clinical examination is crucial to avoid diagnostic errors. Approximately 15% of patients have greater tuberosity fractures. Arthroscopic Bankart and open Latarjet procedures are often recommended for the treatment of residual instability.
Effects of mining activities on social-cultural development: A case of Kapijipanga chiefdom in Solwezi district of North-Western Province, Zambia
Authors: Nachete Maila  , Chanda Chansa Thelma
Published: June 2024

Overview: This study examined the impact of mining activities on the social and cultural development of Kapijipanga chiefdom of Solwezi District. The study investigated various ways in which mining activities influence the social and cultural identity of local people. Body of knowledge: The findings contribute to a better understanding of the complex relationship between mining activities and social cultural development and offer insight for sustainable development and community well-being in Kapijipanga chiefdom of Solwezi District. Methods: The study employed both qualitative and quantitative methods and descriptive survey design that sampled local people of Kapijipanga chiefdom, mine workers, headmen and chief. The sample size for this study was 150. Data was obtained from respondents by means of interviews and questionnaires. Tables, graphs and pie-charts were used to analyze the quantitative and qualitative data obtained. Data was then analyzed manually in some cases and also, a combination of software MS Access, and MS Excel. Results: The results indicated that the effects of mining activities on social –cultural development in Kapijipanga chiefdom of Solwezi District is negative in the sense that social development is strongly influenced by the loss of farmland, houses, and livelihoods in Kapijipanga chiefdom. Additionally, the study found that mining activities has led to the loss of traditional authority in Kapijipanga chiefdom of Solwezi District. This is because mining projects often require the relocation of indigenous communities and villages to make way for mining infrastructure. Recommendation: The government of Zambia through the Ministry of Tourism, Arts and Culture and the Department of culture should ensure that mines offer cultural awareness training programs for their employees to increase understanding and appreciation of local customs, traditions, and languages.

Teenagers have a strong interest in being accepted by their peers, so some teenagers have difficulty behaving assertively. The aim of this research is to obtain an inventory that can be used to determine the level of assertive behavior in junior high school students. This research adapts the Gregory model instrument development steps which consist of defining tests, selecting scales, constructing items, testing items, revising, and developing norms. The instrument was developed from Alberti and Emmons' theory which reveals that aspects of assertive behavior are the ability to do something according to one's abilities, express oneself, defend oneself, express opinions and respect the rights of others. The assessment of the instrument developed was carried out based on input from two experts and trials carried out on 137 students in the city of Yogyakarta. Data analysis was carried out qualitatively based on expert input and quantitatively to test the validity and reliability of the instrument using the RASCH model. This research produces an inventory of assertive behavior that has been declared appropriate by experts, with reliability in the sufficient category, the quality of statement items in the special category and statement items declared to have model fit. It is hoped that the inventory developed can be used by guidance and counseling teachers in identifying students' assertive behavior so that it can be used as consideration in preparing service programs.

The preparation of logistics for services in hospitals is very important because, without adequate logistics in terms of quantity, specification of goods, and accuracy of distribution, it is certain that services will be disrupted. In addition to preparing logistics, the logistics sector is responsible for implementing orderly administration in the logistics, equipment, and household sectors. The logistics sector prepares plans for the needs and procurement of logistics materials, compiles maintenance plans, compiles periodic reports on the condition of materials needed and installation equipment, and makes evaluations and suggestions regarding the use of materials/equipment and equipment (storage, management of materials or equipment and office inventory items) in all units in the hospital. This study aims to identify causes and provide solutions through effective strategies to improve logistics management at Gambiran Hospital, Kediri City. The method used is a fishbone diagram (Fishbone), USG method (Urgency, Seriousness, Growth), and SWOT analysis (Strength, Weakness, Opportunity, Threat). Based on the study results it was obtained to determine problems related to effective strategies to improve logistics management at Gambiran Hospital, Kediri City. The solutions proposed to overcome these problems are through optimizing regulations and strategies procurement in improving logistics management at Gambiran Hospital, Kediri City, in the form of implementing an MoU (Memorandum of Understanding) with third parties regarding the repair of equipment contained in the medical device maintenance service contract and implementing a logistics procurement strategy using the umbrella contract method.

METHODS OF INFLUENCE ON THE SYSTEM TO CHANGE THE ENERGY STATE OF SUBSTANCE: EXPERIENCE, STATE OF THE ISSUE

Methods of influencing the system, the ultimate goal of which is to destruct the natural structure of the material, can be divided as mechanical, physical, chemical, biological and complex. The changing the energy state of a substance is called activation. The current scientific field of ultradispersed materials and physical and chemical processes caused by dispersion is created by the researches of many scientists. Detailed consideration for the increasing reactivity of a solid substance compared to the change in its specific surface area during its mechanical activation showed that the share attributable to the growth of the specific surface area is only a few percent of the mechanical activation effect. The other part is due to the accumulation of defects in the crystals during the grinding process. According to the law of conservation of energy, when a crystal splits, the potential energy of interaction between lattice nodes is transferred to uncompensated surface energy. In addition, the value of the specific surface energy depends on the type of flat lattice used to split the crystal. Therefore, the activation processes and the application of the substance in the active state are relevant in the development of modern binders and concretes. The purpose of the article is to analyse the advantages and disadvantages of the existing methods of influencing the system with the ultimate goal of destruction of the natural structure of the material to changing the energy state of the substance, i.e. its activation. Conclusions. During the destruction of solids, the formation of new cleavage surfaces is accompanied by the breaking of bonds between the substance structural elements and the transition of the potential bond energy into surface energy. Ceteris paribus, the higher the ionic charges and the smaller the distance between them (between adjacent flat grids in the lattice), the greater the value of σ. In addition, the value of the specific surface energy depends on the type of flat grids used to split the crystal. It is worth mentioning that not all methods of activation for binder and concrete (soluble) mixtures are currently implemented on an i industry level. This is due to various reasons. The main method of activation used on an industry level is mechanochemical activation in various types of mills.

A modified technique for determining the characteristics of the goniometer discriminator in a monopulse radar using the method of amplitude instantaneous comparison is proposed. Its distinctive features from the generalized technique are: in determining the minimum number of intermediate points of the interpolating function of the discriminatory characteristic of the discriminator, followed by calculating its maximum deviation from the theoretical discriminatory characteristic; in estimating the steepness of the discriminatory characteristic at each intermediate point; in calculating the fluctuation characteristic of the discriminator by estimating the variance of the error signal of angular coordinates at intermediate points of the discriminatory characteristic; in using the interpolating steepness function and the fluctuation characteristic of the discriminator for mismatches smaller than the step of change of intermediate points. The results of mathematical modeling of the discriminatory and fluctuation characteristics of the discriminator of the goniometer using the proposed technique are presented.

Background. Naked barley is a promising food crop. To enhance its production, active breeding is required to create productive varieties. The purpose of this study was to test the STS-marker for the Nud1 gene controlling the hulled phenotype, and use it for the production of naked barley hybrids. Materials and methods. Genotyping of 112 F2 hybrids obtained by crossing the naked black variety ‘Jet’ and the hulled white variety ‘Elf’ was carried out using wF2 and kR1, or tR2 primers in the regular PCR mode to amplify the recessive or dominant alleles of the Nud1 gene, respectively, and also in the multiplex PCR mode, which allows simultaneous amplification of both dominant and recessive alleles of the Nud1 gene. The genotyping data were compared with those on phenotypes of hybrids. Results and discussion. The possibility of using multiplex PCR with a set of primers wF2, kR1, and tR2 for identifying dominant and recessive alleles of the Nud1 gene in hybrid material has been demonstrated. However, while the observed number of hybrids homozygous for the recessive allele nud1 almost completely corresponded to their expected number, the clear predominance of homozygotes for the dominant allele Nud1 and the lack of heterozygotes compared to the expected number of hybrids of these groups indicates erroneous identification of some heterozygotes as dominant homozygotes, which must be taken into account during selection of hulled barleys by genotyping. Conclusions. The STS-marker amplified by primers wF2, kR1, and tR2, can be used to select recessive homozygotes nud1nud1 from hybrid populations, however, additional analysis is required for a more reliable identification of heterozygotes and homozygotes for the dominant allele of the Nud1 gene.
