Published: October 2021

Currently, the most promising direction of breeding is the creation of F1 hybrids of sugar sorghum, based on the identification and selection of parental forms with high combinational ability. The source material and F1 hybrids were grown in the arid conditions of the Saratov Right Bank (Russia): the hydrothermal coefficient during the growing season was 0.68. The evaluation of the combinational ability of crossing components was carried out using the topcross method. As a result of the tests, the L-52/13 line was identified with high GCA effects (15.71), and the highest SCA dispersions were found in the Saratovskoe 90 variety and the L-39/12 line (91.80-189.27). It was found that the type of sterile cytoplasm of iso-nuclear CMS-lines had a significant impact on the manifestation of SCA in terms of biomass yield: higher dispersion indicators were noted in 9E Zheltozernoye 10 (36.66). Genes with an additive effect are involved in the genetic control of this trait in paternal forms, and non-additive genes in maternal forms. In addition, each hybrid combinationwas observed with superdomination: the coefficient of phenotypic dominance varied from 2.01 to 18.91. It is advisable to use the obtained information in the hybridization of sugar sorghum to obtain high-heterosis hybrids.

Authors: Bryksin D.M.
Published: October 2021

Blue honeysuckle has successfully become one of the industrial berry crops of the XXI century. The area of blue honeysuckle plantations in Russia exceeds 500 hectares. More than 210 varieties of blue honeysuckle of Russian and foreign breeding were collected at the experimental sites of the SPC “Agropishcheprom”. As a result of the breeding work carried out, the Michurinskoye Divo blue honeysuckle variety, which has a set of requirements for industrial varieties, was transferred to the state variety testing. The main problem when laying commercial blue honeysuckle plantations is the lack of high-quality planting material of new varieties. Planting material of blue honeysuckle, on an industrial scale, is obtained in several ways: hardwood cuttings, soft wood cuttings and in vitro method. The work presents the results of studying the influence of planting material obtained by various methods and used when establishing plantations for the growth, development and formation of productivity of the Michurinskoe Divo blue honeysuckle variety. The positive influence of the in vitro propagation method for the qualitative indicators of the root system of the obtained seedlings, growth activity, potential productivity and yield in the production plantings of the Michurinskoe Divo blue honeysuckle variety, in comparison with seedlings obtained by other reproduction methods, was revealed.

Authors: Kaipov Yakhiya , Akchurin Rifkat , Kirayev Rustam , Nizaeva Asiya
Published: October 2021

Field experiments were conducted in the arid steppe zone of the Southern Urals, in the Republic of Bashkortostan of the Russian Federation. The soil is common chernozem. The precipitation during the growing season (May-September) is 166 mm. The experimental crop rotation consisted of 7 fields: 4 with perennial herbs (a mixture of Bromus inermis and Medicago varia), 3 with annual crops. The study analysed soil properties and carrying capacity in perennial grass rotation, conventional and reduced tillage. During the crop-pasture rotation, the humus content in the soil changes insignificantly depending on the tillage, being within 7.6-8.0 %. Perennial grasses loosened the soil, positively affecting moisture accumulation under crop rotation by the beginning of the pre-sowing period. The arable layer of common chernozem in the reduced tillage had a density of 1.05 g/cm3, less than 0.06 g/cm3 in conventional cultivation. Fertilizer application increased yields at 0.49-0.51 t/ha of feed units. Reduced tillage resulted in higher feed units by 0.06-0.08 tons per 1 ha. Crop-pasture rotation implementation and development ensures bioclimatically-determined yields of fodder crops and maintains soil fertility at an optimal level.

Authors: Feoktistova N.A. , Eremina D.V.
Published: October 2021

The results of long-term stationary studies on the influence of farming system elements on the yield of spring barley in the forest-steppe zone of the Trans-Urals are presented. In the experiment, the role of the precursor; the main tillage (plowing and surface scarification); three levels of mineral nutrition were studied. The variation of the barley harvest for 2004-2014 under the influence of weather conditions that have direct and indirect impact on the formation of the yield of cereals is shown. The yield of barley primarily depends on the level of mineral nutrition. The average yield of barley sown after peas was 3.52 t/ha, with a variation in the range of 2.40-4.24 t/ha. In the variant where the precursor was oat, the yield of barley was 3.39 t/ha with a variation from 2.11 to 4.72 t/ha. The share of the contribution of the growing season weather conditions is 49% (the precursor is peas) and 72% (the precursor is oat). The minimum yield over the years of research was 1.44 t/ha on the variant where the precursor was oat, fertilizers were not applied, and the main tillage was surface scarification. The maximum yield was 5.57 t/ha on the variant with a dose of fertilizers N54P52K52 kg/ha, which were introduced by plowing.

Published: October 2021

The main source of soil fertility decline in the arid conditions of the Orenburg region is erosion, which manifests itself to varying degrees over the entire arable land. In the Orenburg region, 2214.9 ha are subject to water erosion, wind erosion - 279.4 ha, and out of a total area of 6240.0 thousand hectares, deflationary hazardous erosion - 5304.3 thousand hectares. In connection with erosion processes, the humus content in the soil decreases by 1-6 tons in southern chernozems, ordinary -1.7%. The studies were carried out in two stationary areas of the Orenburg Cis-Urals and Trans-Urals in order to determine the efficiency of measures and technologies to preserve soil fertility and protect the soil from erosion in arid conditions. With the transition to contour-landscape agriculture (CLA), the fertility of slope lands and the yield of field crops increases, and the negative effect of drought decreases to a minimum. The decrease in soil fertility caused by the erosion process is recorded in the fallow field when it is allocated for spring wheat. Soil-protecting and green fallows largely eliminate this disadvantage. During the fallowing period as per the data, the field of black fallow accumulates 430 kg per 1 ha of nitrates in the 0-150 cm layer, and when mineral fertilizers are applied at a dose of N40P80, it increases to 689 kg per 1 ha.

Published: October 2021

The paper studies the processes of transformation of the molecular structure of humic (HA) and fulvic acids (FA) of leached chernozem under the influence of fertilizers and meliorant. The research was carried out under the conditions of many years of stationary experiment of the Department of Agrochemistry, Soil Science and Agroecology of the FSBEI HE Voronezh SAU. Samples of leached low-humus thin heavy-loamy chernozem were analyzed. The isolated and purified preparations of HA and FA were studied on a SM2203 spectrofluorimeter in the ultraviolet and visible ranges. The paper also presents the results of determining the most important physical and chemical properties of soil variants using various fertilizer and meliorant systems. Limed variants have optimal indicators. Based on the analysis, it can be assumed that the FA molecules of the variant with a double dose of mineral fertilizers on the background of manure differ in a developed aliphatic part, have many auxochromic substituents. HA of the same variant are characterized by a high condensation of nuclear structures. The HA and FA molecules of the variant with the joint application of fertilizers and meliorant have a more complex structure of the nuclear and peripheral parts. According to the results of calculations of extinction coefficients, it was found that liming contributes to the accumulation of more mature forms of humic acids.

Cocksfoot is one of the earliest, highly nutritious valuable forage crops, which is widely used in agricultural production. It is relevant in developing varieties adapted to the environmental stress factors that have productive longevity, increased seed and fodder productivity. The paper presents the results of wild cocksfoot accessions conducted on Ekaterininskaya RS in 2017-2019. No accessions of cocksfoot were identified that consistently exceeded the standard grade for all three years of study. Accessions collected in the North Caucasus and Tajikistan and introduced from the Mediterranean region performed well in the first year of life, but by the third year of the life, they significantly reduced all characteristics. The accessions of cocksfoot from the Central Region of the European part of the RF and from the mountainous regions of the Southern Urals are of the greatest interest for breeding in the Central Chernozem zone.

Published: October 2021

The article presents data from the effectiveness studies of the initial introduction stage of black currant (Ribes nigrum L.) into in vitro culture depending on the introduction period and the corresponding climatic conditions. The research objects were varieties of black currants selected by the Russian Research Institute of Fruit Crop Breeding: Azhurnaya, Orlovskaya serenada, Ocharovanie, Chudnoye mgnovenye. The introduction into in vitro culture was carried out in several periods characterized by different physiological states of the explants: the period of dormancy release (mid-March), the period of active growth (June), and the period of growth decay (mid-September). The source material in the spring and autumn periods were the buds of one-year stiffened shoots, in the summer introduction period - the buds of growing green shoots. The cultivation was carried out on Murashige-Skoog medium supplemented with 6-BAP (0.5 mg/l). It was noted that the survival rate of explants is determined by the physiological state of the source material due to the corresponding agro-climatic conditions during the introduction period, as well as the genotypic characteristics of the varieties. Thus, explants isolated during the active growing season are characterized by a higher and more stable survival rate. When explants were cultivated in spring and autumn, the physiological state of the explants and their survival rate were influenced by the genotypic response of varieties to the corresponding agroclimatic conditions.

The article presents the results of studying the radio protective properties of alfalfa extract (dietary supplement "Erakond"). A decrease in the iron content in macrophages of the red pulp of the spleen was found experimentally using models of experimental radiation pathology induced by ɣ-irradiation of white rats in a single dose of 4 Gy at a dose rate of 1.7 Gy/min. The mechanisms of pathological processes in acute radiation pathology, leading to a decrease in the content of endogenous iron at the systemic, organ, cellular and subcellular levels, have been disclosed. Violation of the processes of enteral absorption of minerals as a result of pronounced destructive-inflammatory processes in the intestinal wall, damage to the hematopoiesis-inducing environment in the red bone marrow, inhibition of cytokine synthesis (IL-1, IL-3, IL-6, IL-7) and granulocytic macrophage colony-stimulating factor (GM-CSF) reduce the level of deposited iron in acute radiation pathology. In rats treated with 40 % "Erakond" aqueous extract before and after irradiation, there is a relatively high level of deposited iron in the spleen tissues in comparison with animals of the comparison group, which were on a general food ration.

The state of humoral immunity in lactating sows and its formation in suckling piglets in the conditions of a pig-breeding complex were studied. In sows after farrow, a high content of total immunoglobulins, the main classes of IgG, IgM and IgA, the concentration of which decreased in a day, followed by an increase in serum as lactation continued was detected in the serum and colostrum. In piglets at birth, the content of total immunoglobulins and the main Ig isotypes was insignificant, and at the age of twenty-four hours, as a result of absorption of colostral immunoglobulins in the small intestine, their amount in the serum was the highest, followed by a decrease in the concentration of IgG and IgA until the end of the suckling period, and IgM - up to day 14 with a further increase in its content, indicating the formation of a primary immune response. It has been detected that the dominant class of immunoglobulins in the serum and colostrum of sows and the serum of piglets is IgG, and in milk - IgA. An increase in the level of medium-dispersed circulating immune complexes (C4%) and their relation to giant (C3%) CICs was revealed, associated with an increase of the antigenic load in sows in the second half of lactation as a result of immunization, in milk - with a decrease in the content of the main classes of immunoglobulins, and in piglets, due to this, with a decrease in passive immunity.

One of the key areas of development of the cattle breeding industry in Russia is the creation of effective technological methods. They allow to carry out the improvement and establishment of new resource-saving systems for breeding young animals at an accelerated pace. It is essential to meet the modern requirements of meat production as an ecologically safe product. The aim of the research was to enhance the fattening qualities of Hereford bull calves while using mode-setting suckling of various ratios as an element of resource saving. The study was performed on "SAVA-Agro-Yapryk" OOO of the Tuymazinsky district of the Republic of Bashkortostan. The determination of the efficiency of the use of free and mode-setting suckling of various ratios made it possible to identify an effective method of raising young meat cattle. A three-fold mode suckling is used with separate keeping of young animals and mother cows. This makes it possible to keep the optimal microclimate parameters in the calf house, contributes to the rapid early adaptation of calves to the consumption of coarse feed and concentrates. It has a positive effect on the growth and development of calves and their meat productivity at the age of 18 months according to the parameters of removable fat mass, carcass mass and interior fat mass. All this promotes an increase in the sale of beef and an improvement in the level of production profitability to 13.93%.

When carrying veterinary and sanitary expertise we often come up the attempts of meat products adulteration, for example when livestock meat is replaced to wild one and vice versa. Most often such adulteration cases are the results of illegal hunting. The purpose of our work is study horse and Manchurian wapiti carcasses anatomic features. The main methods of meat species determine are analysis of carcass appearance, organoleptic parameters analysis, laboratory tests as well as analysis and feature examination of anatomic structure of the inspected carcass. To determine meat species we applied methods of comparative and anatomic examination, organoleptic parameters analysis of meat samples, and laboratory tests. The suggested methods of examination can be used not only for determination of the whole animal carcasses species, but for small parts of the body. It is of great importance in conducting forensic and veterinary researches, when the number of parts can be finite. Maximal efficiency can be achieved only with complex use of enumerated methods.

Of the acute respiratory viral infections in the farms of the Udmurt Republic, parainfluenza-3, respiratory syncytial infection, infectious rhinotracheitis, viral diarrhea are the most common. For the prevention of these cattle diseases, the inactivated combined vaccine Kombovak and Kombovak R. is used. Despite the widespread use of this vaccine, there is an ambiguous situation in the farms of UR and the percentage of ARVI incidence is extremely variable. Along with general economic factors, this can be explained using different schemes for the use of the vaccine. The work was carried out in the conditions of an industrial livestock complex located in the Uvinsky district of the Udmurt Republic. During the period of the work, 1,383 heads of cattle vaccinated with the Kombovak-R vaccine were monitored. Laboratory tests were carried out in the BI UR "Udmurt Veterinary Diagnostic Center" in the city of Izhevsk and LLC "Independent Veterinary Laboratory "Chance-Bio" in the city of Moscow. Determination of immunity intensity and retrospective serological diagnosis of ARVI was carried out by examining paired blood serum samples. Blood serum samples were taken from clinically healthy cows at the 6th month of pregnancy, i.e. at the end of the inter-vaccination period, as well as from unvaccinated calves with a live weight of 50-55 kg at the age of 17-18 days and after 21 days, respectively. When studying the preservation of post-vaccination immunity in cows, it was found that only two out of five studied animals have a protective level of antibodies to acute respiratory viral infections by the end of the inter-vaccination period. Serological screening of calves showed that antibodies to the pathogens of IRT, VD, RSI and PI-3 were determined in all samples. nevertheless, the titers of antibodies to ARVI pathogens differed significantly.

Producing high-quality fodder is one of the most urgent priorities in agriculture of the Bashkortostan Republic. The Sudangrass cultivation can address the issue of getting high-quality animal feed in the region. The given paper presents the results of experimental studies on improving the Sudangrass growing technology in the conditions of the Bashkortostan's Cis-Ural steppe, based on the best possible and scientifically proven sowing time, methods and seeding rates. Previous studies have established the way these factors affect the productivity of Sudangrass variety Demskaia. It was found that the Sudangrass variety Demskaia requires a seeding rate of 2.5–3.0 million fertile seeds per 1 ha to realize the productivity potential. The best time for sowing Sudangrass is late May when the soil steadily warms up to +14° - +18°C. The highest crude protein content was observed at earlier sowing with the seeding rate of 2.5-3.0 million fertile seeds per hectare. The higher seeding rate results in the increased leaf area and photosynthetic potential but cuts the net productivity of photosynthesis. The leaf surface area reaches its peak in the "full emergence" phase in the trial with a 15-cm row-width spacing at the seeding rate of 2.5-3.0 million fertile seeds per hectare.

The problem of weed control has been facing mankind since the beginning of agricultural development, and is especially relevant today. Weeds began to evolve not only under the influence of natural factors, but also human activities, especially with the introduction of herbicides, which have become the most powerful factor in the evolution of segetal vegetation. Over the past two decades for biodiversity of forests, green areas of settlements and agricultural lands. Invasive species have properties that increase their ability to suppress Aboriginal species populations and compete with them for space and resources. Threats from invasive species are one of the most important environmental problems of our time, which is especially acute in the process of globalization.

One of the main tasks in the coming years will be the development and introduction of vaccines for the development of immunity against intracellular bacterial and viral pathogens. DNA vaccines will play an important role in such cases. With the emergence of intensive industrial fish farms, there were also problems associated with infectious diseases of cultivated objects. These diseases cause significant harm to fisheries and the aquaculture sector of the global economy as a whole. The article shows the way of the development of the environmentally safe and sustainable marine and freshwater aquaculture with using Pisces vaccination, and reveals the role of Pisces aquaculture as an integral part of the world economy, in the face of increasing anthropogenic pressure on aquatic ecosystems and of distribution of new dangerous Pisces infections. Perspective types of Pisces vaccines are presented and discussed. The effectiveness of different types of elaborated vaccines is discussed.

The present work investigates the benefits and challenges of applying surface guided radiation therapy (SGRT) to breast cancer treatments on the Halcyon™ (Varian, USA). Inter-fraction setup accuracy and treatment time were assessed by comparing CBCT shifts registered following SGRT-based vs. standard tattoo-based patient setup in two randomly selected groups of ten breast patients. Next, using a torso phantom and a volunteer, intra-fraction motion tracking accuracy and surface coverage were assessed for 3 adjusted central ceiling camera positions. SGRT was shown to significantly reduce setup errors (mostly within ± 2 mm) compared to tattoos (up to 2.1 cm) in all translational directions (p-value < 0.001). Treatment throughput and efficiency were also significantly improved with SGRT (p = 0.038). Meanwhile, intra-bore surface coverage with an adjusted central SGRT camera proved insufficient, suffering from patient self-occlusions (invisible body parts occluded by patients’ own morphology such as breasts, bellies, arms, etc.) and bore-induced camera obstructions. Tracking accuracy remained satisfactory (sub-0.5 mm) but 6 degrees-of-freedom motion monitoring, critical in stereotactic radiosurgery, stereotactic body radiation therapy and deep inspiration breath hold techniques and clinical applications, was not possible. Standard ceiling-mounted SGRT systems reduce inter-fraction breast setup errors and treatment duration while intra-fraction motion tracking is insufficient for O-ring linear accelerators.
Energy Analysis of A Hybrid Wind-Wave Solution For Remote Islands

Published: October 2021

The energy needs of most Aegean islands are covered by the operation of autonomous/local power stations (APS/LPS) using imported oil. The costly operation of the APS/LPS combined with the resulting environmental problems, set the issue of a sustainable and rational energy solution mainly for the remote islands, showing respect to the sensitive island ecosystems and the acceptance of local communities. In this context, high wind speeds as well as the remarkable wave potential of the Aegean Archipelagos could be the driving force for a sustainable energy supply solution for these islands by exploiting combined energy sources along with an appropriate energy storage system, comprising a modern hybrid renewable based station. Moreover, the exploitation of wave energy is one of the future priorities of the European Union (Blue Growth) in an effort to support the installation of wave energy converters, which are in the final stage of technological development. The proposed analysis examines the combined exploitation of the wave and wind potential for a representative medium sized island of the Aegean Archipelagos in order to cover its electrical needs. The results show that the installation of a hybrid power station contributes to a higher integration of renewable energy systems (RES) into an autonomous micro-grid and that the stochastic production of wind turbines can be counterbalanced due to the smoother (time-dependent) production of wave systems. In addition, the ability to store excess renewable energy enhances the energy supply security of an island micro-grid providing a clean energy solution for the remote Aegean island communities and thus reducing their oil dependence.

Authors: Max Julianna , Heilmann Jörg
Published: October 2021

1H NMR-guided fractionation of the petroleum ether extract of the aerial parts from Hypericum hirsutum yielded to the isolation of 19 polyprenylated polycyclic acylphloroglucinols. Structure elucidation based on 1D and 2D NMR spectroscopy together with high-resolution electrospray ionization mass spectroscopy revealed 14 acylphloroglucinols with a homoadamantane scaffold (1–14), while 5 further compounds showed an adamantane skeleton (15–19). Except for hookerione C (15), all isolated metabolites are hitherto unknown. While structurally-related metabolites have been isolated from other Hypericum species, it is the first report of admantan and homoadamantan type acylphloroglucinols in section Taeniocarpium Jaub. & Spach (Hypericaceae). The isolated compounds have been tested in a crystal violet-based in vitro assay on their properties to reduce the proliferation of human microvascular
endothelial cells compared to hyperforin as the positive control. They showed a moderate reduction of proliferation with IC50 values in the range ~ 3 – 22 µM, with the homoadamantane-based compounds 2 and 4 being the most active. In addition, inhibition of the TNF-α-induced ICAM-1 expression was determined for 1 – 5, 7, and 10 – 12. Substances 3 and 12 reduced the ICAM-1 expression significantly (to 46.7% of control for 3, 62.3% for 12, at 50 µM).

Authors: Al-Samman Abdurrahman A. , Al-Ani Rand Sh.
Published: October 2021

Objective Osteonecrosis of the jaws is the adverse effect of antiresorptive and antiangiogenic agents, which is termed as medication-related osteonecrosis of the jaws (MRONJ). This complication, which is prominent and growing, is seen in the oral and maxillofacial region. This cross-sectional survey aimed to evaluate MRONJ awareness among Iraqi medical specialists.

Materials and Methods A questionnaire-based survey was performed on medical specialists practicing general surgery, urology, orthopedics, rheumatology, and oncology. The questionnaire consisted of four questions regarding drug prescription, patients’ preparation before drug administration, in addition to awareness and knowledge about MRONJ.

Results Among 132 specialists, 57% did not prescribe such drugs. A significant difference existed among groups regarding dental referral, and MRONJ awareness and knowledge. The highest rates were seen in the oncologist group.

Conclusions Improvement of MRONJ perception and knowledge among medical specialists, besides implementation of dental referral, are essential in the prevention, diagnosis and treatment of MRONJ.
