Evaluation of the effect of some treatment regimens of dry cows with genital Mycoplasmosis on the protein metabolism of their offspring

Modern political realities force us to rely on the development of our own agricultural production in order to ensure the country's food independence. To achieve this goal, it is necessary to increase its production while increasing profitability. In industrial animal husbandry, the main reserve for the implementation of this task is to reduce the incidence of animals and obtain healthy offspring from them. In this regard, the development of inexpensive and effective ways of diagnosing treatment becomes relevant. This is of the greatest importance for a group of diseases characterized by a long latent period and erased symptoms, which include genital mycoplasmosis of cattle. The purpose of the research was to study the use of the antibacterial drug tulatromycin and its combination with the immunomodulator thymalin in pregnant cows with genital mycoplasma on the protein metabolism of their calves. To conduct the experiment, three experimental groups of calves from cows with genital mycoplasmosis were formed, calves from clinically healthy animals served as controls. The total protein, protein fractions, classes of immunoglobulins and their proportion in the globulin fraction were determined in all groups. During the experiment, it was found that calves from infected cows have pronounced dysproteinemia. The use of tulathromycin for the treatment of cows leads to a partial restoration of the content of immunoglobulins in their offspring, whereas the combination of both tulathromycin and thymalin applied to pregnant cows ensures the restoration of all studied indicators in calves born by them to the level of their healthy peers.

Efeito do ferro e cobre na emergência e fisiologia de Canavalia ensiformis (L.) DC

ABSTRACT Plants require iron (Fe) and copper (Cu) at low concentrations for metabolic functions; however, excess soil Fe and Cu can cause toxicity and affect plant development. The objective of this study was to assess the effects of soil Cu and Fe concentrations on seedling emergence, as well as on the metabolism of the main reserve compounds and the biomass in roots, stems, leaves, and cotyledons of Canavalia ensiformis. A greenhouse experiment was conducted in a completely randomized design; the Cu and Fe treatments in the soil were: (control, 50, 150, 250 and 350 mg dm-3) over a period of 10 days. Seedling emergence was not affected by the evaluated treatments; however, the results showed an increase in the emergence speed index (EVI) for the Fe treatment at a dose of 150 mg dm-3 of soil compared to 350 mg dm-3 of soil. Treatment with Cu at a dose of 350 mg dm-3 of soil reduced root length. Cu treatments reduced root dry mass. Fe treatments affected the content of soluble amino acids in the stems, leaves and cotyledons, as well as the total soluble proteins in the cotyledons and the carbohydrate content in the leaves. Cu treatments increased protein and carbohydrate content in leaves and starch content in cotyledons. High concentrations of Cu and Fe modify the production of nitrogenous compounds in the plant and reduce root biomass.

Оценка запасов углерода в почвах лесов юга Приморья

The main reserves of organic matter of terrestrial ecosystems of the planet are accumulated in forest soils. The patterns of changes in carbon stocks depending on the location in the relief and vegetation in Haplic Cambisols (brown soils typical) of broad-leaved forests of the western spurs of the Sikhote-Alin Primorsky Territory are studied. Haplic Cambisols of the south-southeastern and north-northwestern slopes morphologically differ in the thickness of the genetic horizons and the degree of stony. Their carbon reserves vary depending on the location and the prevailing tree species, and they gradually increase in soils from the watershed downhill to the foot. The largest carbon reserves were found in the soils of the floodplain of the stream in the area of birchash mixed forest (104–108 t/ha in layers 0–30 and 0–50 cm), the smallest – in the soils of the steep slope of the southern exposure under xerophytic oak forests (65–67 t/ha, in layers 0–30 and 0–50 cm). The data obtained fully correspond to the assessment of carbon reserves in soil layers for the Primorsko-Priamursky coniferous-deciduous region of the Far East. Close relationships have been revealed between the content of exchangeable bases, organic carbon, available forms of nutrients (phosphorus and potassium), actual acidity and the content of the fraction of physical clay.

The data collection for a sample collected in the summer and analyzed revealed a pH of 6.8 and the presence of 19 chemical elements using the technique with concentrations in the order of ng.mL -1 , with emphasis on the presence of lead (Pb).

Physiological research of young Russian sturgeons in modern ecological conditions of the Caspian sea

In the Volga-Caspian fisheries basin, artificial reproduction of sturgeon species is the primary source of replenishing their natural populations. The aim of this study is to conduct physiological research on juvenile Russian sturgeon (Acipenser gueldenstaedtii) in the western part of the Northern Caspian Sea, to establish the features of fish homeostasis. The physiological condition of the specimens was studied using a set of physiological and biochemical parameters. Hematological, biochemical, and morpho-histological parameters were evaluated. In the blood of the fish, the contents of hemoglobin, total protein, glucose, inorganic phosphorus, calcium, creatinine, bilirubin, total lipids, cholesterol, and triglycerides were determined. In the muscle tissue of juvenile Russian sturgeon, the physiological and biochemical indicators studied included the content of the main reserve substances of the body — total lipids and water-soluble protein. Histological methods were used to assess the morpho-functional state of the gills. The variability of physiological and biochemical parameters in juvenile Russian sturgeon was calculated using descriptive statistics based on parametric and non-parametric criteria in the blood and muscles. According to the results of correlation statistical analysis, significant changes were observed in the tissues of the sturgeon juveniles, aimed at providing the body with sources of energy and nutrients used for the functioning of body tissues and serving as reserve stocks, as well as maintaining regulatory mechanisms of metabolism and its changes depending on fluctuating environmental conditions. The morphological examination of the gills revealed vascular disorders, hyperplasia, swelling, and hypertrophy of the respiratory epithelium cells, corresponding to borderline disturbances from mild to moderate damage, which was the organ’s response to external environmental influences.

A review on bacterial enriched vermicompost and its applications

Generation of the massive quantity of solid waste around the globe is a major ecological and technical problem. Vermicomposting may be the viable option to handle solid waste in an environmentally friendly way. Vermicompost have higher level of available nutrients like carbon, nitrogen, phosphorous and potassium, calcium and magnesium which are derived from the wastes. Many researchers have attempted to evaluate for development of efficiency vermicompost by using varieties of earthworms. The use of earthworms in the degradation of different types of wastes is continuing from the past so many years. These wastes include industrial, agricultural of plant debris and domestic waste papers and cattle dung. Fixed nitrogen is a limiting nutrient in most environments, with the main reserve of nitrogen in the biosphere being molecular nitrogen from the atmosphere. Molecular nitrogen cannot be directly assimilated by plants, but it becomes obtainable through the biological nitrogen fixation process that only prokaryotic cells have developed. Vermicompost is an effective carrier for bacterial growth so that the symbiotic bacterial species such as Mycorrhiza and Dyaztotor of helps in the rapid growth of plant while Azotobactor, Rhizobium involves in the fixation and storing of nitrogen for plants. This review focus on the vermicomposting and microbial enrichment of vermicompost for the exceed crop production.

Qualea grandiflora Mart. (Vochysiaceae) seed reserves and aluminum: Usage and mobilization during germination and seedling development

AbstractQualea grandiflora Mart. is an aluminum (Al)‐accumulating Cerrado species with a metabolic dependency on Al. This study aimed to determine the presence and concentration of Al and other reserve components in Q. grandiflora seeds, as well as their respective distribution patterns, mobilization, and usage during germination and seedling growth. Thus, the concentration of Al and other minerals in seeds, seedlings, and soils was measured. Also, histochemical and energy‐dispersive X‐ray spectroscopy (EDS) analyses were performed to observe the distribution of Al, proteins, and lipids in Q. grandiflora seeds and seedlings. Additionally, the concentration of proteins and lipids was assessed as well. Hence, even in soils with low exchangeable Al3+, Q. grandiflora seeds accumulated about 6.43 g of Al/kg of dry matter (DM) together with considerable concentrations of N, P, K, Ca, and Mg. Exogenous Al had no effect on the germination properties of Q. grandiflora seeds. Furthermore, approximately 60% of the seed Al was translocated to seedling leaves. Proteins and lipids were the main organic reserves in Q. grandiflora seeds. The histochemical analysis revealed that the bulk of Al in seeds was in the cotyledons, which were also the location sites of proteins and lipids. Proteins and lipids were the primary source of energy and carbon for seedling growth. Therefore, fatty acids, proteins, and Al could play a central role during seed germination and seedling establishment, which could help to explain why this species is one of the most widespread plants in the Cerrado.

The elongation factor 1-alpha as storage reserve and environmental sensor in Nicotiana tabacum L. seeds

Given their critical role in plant reproduction and survival, seeds demand meticulous regulatory mechanisms to effectively store and mobilize reserves. Within seeds, the condition of storage reserves heavily depends on environmental stimuli and hormonal activation. Unlike non-protein reserves that commonly employ dedicated regulatory proteins for signaling, proteinaceous reserves may show a unique form of 'self-regulation', amplifying efficiency and precision in this process. Proteins rely on stability to carry out their functions. However, in specific physiological contexts, particularly in seed germination, protein instability becomes essential, fulfilling roles from signaling to regulation. In this study, the elongation factor 1-alpha has been identified as a main proteinaceous reserve in Nicotiana tabacum L. seeds and showed peculiar changes in stability based on tested chemical and physical conditions. A detailed biochemical analysis followed these steps to enhance our understanding of these protein attributes. The protein varied its behavior under different conditions of pH, temperature, and salt concentration, exhibiting shifts within physiological ranges. Notably, distinct solubility transitions were observed, with the elongation factor 1-alpha becoming insoluble upon reaching specific thresholds determined by the tested chemical and physical conditions. The findings are discussed within the context of seed signaling in response to environmental conditions during the key transitions of dormancy and germination.

Work process management: essence, characteristics and ways of improvement

The article is devoted to the study of the peculiarities of the legal regulation of the management of the labor process and the possibilities of its improvement in the process of reforming the domestic labor legislation. Since today the issue of managing the labor process is of particular importance, taking into account the existing shortcomings in this area, the protracted process of reforming the labor legislation and adopting the Labor Code of Ukraine. In particular, the modern conditions of strengthening integration processes lead to the need to develop fundamentally new approaches to the management of the labor process with the awareness that the main reserve of the enterprise are employees who ensure the quality and competitiveness of production results. Especially today, when employers in the conditions of martial law have a lot of questions about reformatting relations with employees. And in order to maintain a high quality of management, they need to respond quickly and effectively to such situations. It is noted that the management of the labor process is a planned activity of the company’s management aimed at organizing, regulating, motivating and controlling the work of employees, the purpose of which is to coordinate the collective efforts of the team and ensure the agreed actions of its members aimed at achieving specific planned results. Attention is drawn to the fact that at each enterprise, institution, organization, the management of the labor process has its own specificity and depends on objective and subjective factors. A conclusion was made regarding the expediency of implementing remote management of the labor process. Because the use of effective remote management tools can become effective in the process of labor management, especially with the war in the country. And therefore, in today’s conditions, managers of enterprises need to master the skills of remote management of their enterprises, and in the future actively use them to achieve the tasks set before the management. Since taking into account the frequent change of the environment and the constant acceleration of the pace of life, which directly affect the enterprise, the organization of the process of remote management of the work process at the enterprise will become one of the key factors of successful activity in the market.

Technical and technological support for the involvement of fallow lands in agriculture

Sustainable development of agricultural production is a key factor in ensuring food security and growth of the country's export potential. One of the main reserves for the development of the agro-industrial complex is the involvement of fallow lands in agricultural industry, which is associated with the problem of technical and technological support for these works. The purpose of the work is to intensify the process of involving fallow lands in agriculture by developing a program of technical and technological support for this type of works, aimed at creating and accelerated implementation of a system of specialized machines. The authors systematized technologies and complexes of technical means, used in the involvement of fallow lands in crop production, depending on the stages of wild species overgrowth. For active involvement of fallow lands in agriculture, it is proposed to create a network of regional machine-technological stations equipped with modern domestic specialized equipment, providing services in removal of woody and shrubby vegetation and in initial tillage to agricultural producers in regions. The program assumes the development and organization of mass production of modern equipment for the involvement of fallow lands in agriculture, as well as implementation of a set of support measures aimed at accelerated technical equipment of machine-technological stations. Such an approach should make it possible for small and medium-sized agricultural producers to use financially affordable machinery services to involve fallow lands in agriculture, eliminating the need for its acquisition and maintenance, hiring and training of additional stuff. The implementation of the proposed program should allow agricultural producers to involve fallow lands in agricultural production with minimal costs, at the same time ensuring high growth rates of acreage and agricultural production volumes.

FEATURES OF DEVELOPMENT OF BASHKORTOSTAN OIL FIELDS IN CARBONATE SEDIMENTS

The main oil reserves on the territory of Bashkortostan lie in terrigenous sediments. Intensive drilling and long development periods have led to the fact that oil reserves in terrigenous deposits have been significantly depleted. In the last decade, 80 % of the increase in reserves was provided by carbonate deposits. The share of remaining oil reserves in carbonate reservoirs has been steadily growing over the past 20 years and by the beginning of 2023 amounted to 32 %.The low efficiency of waterflooding of carbonate sediments and, at the same time, the achievement of high recovery factors with dense well patterns, characteristic of a water-pressure regime, are explained by the hypothesis put forward of the formation of vertical and inclined man-made cracks during the process of percussion-rotary drilling of wells.It is substantiated that when carrying out geological and hydrodynamic modeling it is necessary to take into account the presence of man-made cracks in vertical and inclined direc-tions and hydrodynamic connection through dense reservoirs with underlying water-saturated porous rocks. It is recommended to continue studying the influence of man-made fracturing in horizontal wells and in open-bottom wells on the technological indicators of the development of an oil facility.

The paper examines the peculiarities of financial control and audit in the field of national security, on the basis of the analysis of doctrinal and expert approaches, the directions of organizational and legal support for increasing their effectiveness are determined in the context of reforming law enforcement agencies of Ukraine in accordance with European standards and changing the paradigm of national security protection in the conditions of countering military aggression of the russian federation against Ukraine. The problem of improving the mechanism of financial control and audit in the context of reforming law enforcement agencies is considered as a component of activities aimed at forming a new paradigm of national security, the foundation of which should be an effective system of financial and material resource support, based on effective control mechanisms, built taking into account the need to implement standards of the EU and NATO countries, ensuring compliance with one of the main principles of ensuring national security - matching the costs of countering threats with the financial and economic capabilities of the state. The study takes into account the specific conditions in which law enforcement agencies are being reformed, which include the need to concentrate the main efforts of the State on repulsing military aggression against Ukraine, which began in 2014 in the form of a hybrid war and since 24 February 2022 has moved into the phase of an open full-scale military invasion of the Russian Federation, which in turn causes a huge additional burden on the State budget and partly on local budgets, and is aimed at countering a new range of threats to national security. The paper proposes the main directions and reserves for improving the efficiency of financial control and audit in the field of national security and defence through the introduction of new forms and methods of control, which are an element of the programme-targeted budgeting methodology.

Plant growth regulators and mobilization of reserves in imbibition phases of yellow passion fruit.

The production of seedlings of the passion fruit tree, usually, is sexual, and the seeds are not uniform in the seedling emergence, and soaking treatments of seeds can provide faster and more uniform germination. It was aimed to study the action of plant growth regulators and the mobilization of reserves in the stages of soaking of yellow passion fruit seeds. The seeds were soaked for five hours in solutions containing plant growth regulators, in a completely randomized design, in a factorial 8 x 4, with four replications. The first factor corresponds to eight plant growth regulators: T1 - distilled water (control); T2 - 6-benzylaminepurine ​​500 mg L-1; T3 - 4-(3-indolyl) butyric acid 500 mg L-1; T4 - gibberellic acid 500 mg L-1; T5 - spermine 250 mg L-1; T6 - spermine 750 mg L-1; T7 - spermidine 750 mg L-1; T8 - spermidine 1250 mg L-1; and the second factor, to the four soaking times: zero, four, 72 and 120 hours, corresponding, respectively, to the dry seed, and to phases I, II, and III of the imbibition curve. It was evaluated the biochemical composition of seeds (lipids, soluble sugars and starch). The seeds showed accumulation of lipids in phase III; the content of soluble sugars increased in phase I and decreased in phase II. The starch content increased until the phase II and decreased in phase III. Starch is the main reserve in the seeds and the main source of energy used in phase III; soaking the seeds in polyamines generates an accumulation of lipids in the seeds and soaking in plant growth regulators increases the burning of starch.

FUNCTIONAL CAPABILITIES OF HIGHLY QUALIFIED FEMALE HANDBALL PLAYERS IN THE PREPARATORY PERIOD OF TRAINING

Introduction. Handball as a sport is constantly evolving, demanding from female athletes an enhancement of physical and technical skills, which underscores the need for research into their functional capabilities. Understanding the physiological characteristics of female handball players enables effective planning of the training process, ensuring an optimal combination of endurance, strength, and speed. Identifying the optimal methods of preparing highly skilled handball players is key to increasing their competitiveness at the national and international levels. The preparatory period is crucial for developing the physical condition of the athletes, which directly affects their performance during competitive activities. The relevance of this research is also driven by the growing interest in women's handball and the need to develop specific approaches to training women's teams, taking into account their physiological and psychological characteristics. Aim is to investigate the functional state of handball players during the preparatory period of the stage of maximum realization of individual possibilities. Research material and methods. Material and methods. The study involved athletes of the main squad and reserves of the handball club "Halychanka" in Lviv. The methods included analysis of literary sources and the World Wide Web, pedagogical observation, pedagogical testing, a method of multifactorial express diagnostics of functional readiness, content analysis, meta-analysis, and methods of mathematical statistics.. Results. A significant decrease in the V3R index, which reflects the anaerobic creatine phosphate mechanism of energy supply, was found to be 7.84 units below the established standards. This indicates a limited ability to rapidly mobilize energy in the muscles of handball players, which is critical for short-term high-intensity loads. The average indicators of the anaerobic glycolytic energy supply mechanism were 3.1 units lower than the norm, suggesting less efficient use of muscle glycogen for rapid energy acquisition during medium-duration physical efforts. The assessment of the anaerobic lactate mechanism revealed that it was low in 20% of the handball players and below average in 52%, showing only a medium level in 26% of the participants. This demonstrates variability in the athletes' ability to manage the lactate threshold, which is important for long-term endurance. The index of aerobic energy supply was also found to be 1.33 units below the norm, indicating potential deficiencies in long-term energy supply through aerobic metabolism. Conclusions. A balanced approach to training is key to optimizing the sports results of handball players.

In this context, a balance between public and private funding is important, which will allow the implementation of ambitious projects with maximum benefit for the community.

Ananas ananassoides (Baker) L.B.Sm. a bromeliad from the savanna: seed morpho-anatomy and histochemistry.

Ananas ananassoides (Baker) L.B.Sm. is a wild pineapple, commonly found in the savannas. This study aimed to describe the morpho-anatomy and histochemistry of its seed. The observations were made in the longitudinal and transverse sections, using an optical microscope. The cell arrangement in the seed coat, ripples in the integument, the ratio of embryo size and endosperm amount, and the number of strata in the aleurone layer are anatomical characteristics that may contribute to distinguishing this species. The starch in the endosperm, lipids and proteins in the embryo, constitute the seed's main nutritional reserves. The homogeneous embryo and phenolic compounds present in the seed coat and in the aleurone layer possibly contribute to the dormancy in this species. This study presents information relevant to the taxonomy and physiology of A. ananassoides, which represents contributions to the global knowledge of this species with a high potential as ornamental.
