Parameters of adaptability and stability of winter durum wheat varieties according to various forecrops in the Rostov region

The article summarizes the study results of adaptability parameters of winter durum wheat depending on its forecrop. The study was carried out in the Rostov region in 2015-2017. As the objects of the study there have been used 8 winter durum wheat varieties ‘Donchanka’, ‘Amazonka’, ‘Agat Donskoy’, ‘Kristella’, ‘Lazurit’, ‘Oniks’, ‘Diona’ and ‘Eyrena’. The variety ‘Donchanka’ was taken as a standard variety. In the field trials the varieties were sown after weedfree and green fallows, and after such forecrops as peas, sunflower and maize for grain. The obtained data showed that green fallow was the most favorable forecrop for winter durum wheat, an average yield of which was 7.69 t/ha. When sown after various forecrops, all varieties had different adaptability parameters. The best forecrops were weedfree fallow (‘Kristella’ with 7.78 t/ha, ‘Lazurite’ with 7.74 t/ha), green fallow (‘Agat Donskoy’ with 8.30 t/ha, ‘Lazurit’ with 8.46 t/ha) and peas (‘Oniks’ with 7.41 t/ha, ‘Diona’ with 8.11 t/ha). Among the whole set of the varieties, the variety ‘Agat Donskoy’ (bi>1) proved to be the most highly responsive, while maintaining in most cases high stable yields (si2 <1), productivity of the varieties sown after all forecrops, except sunflower, was 6.93-8.30 t/ha. With productivity increase of 1 t/ha, it improved its indicator (bi) by 1.16-5.15 t/ha. The variety ‘Eyrena’ is recommended for cultivation on an extensive background, since through the years of study it turned out to be the least responsive - with productivity increase by 1 t/ha, it improved its indicator (bi) by 0.01-0.55 t/ha after such forecrops as peas, sunflower and maize for silage

Acute pericarditis: features of diagnosis and treatment in real practice

Background. Acute pericarditis is an inflammatory disease of the pericardium that requires timely and accurate diagnosis to prevent potentially dangerous complications. This article reviews the key aspects of diagnosis and treatment of acute pericarditis in real clinical practice. Due to nonspecific clinical picture and absence of special diagnostic methods, diagnosis of acute pericarditis may cause difficulties. In about one third of patients, the course of the disease is recurrent, which requires assessment of possible risk factors for recurrent episodes of acute pericarditis. The clinical practice of management of patients with OP in the Russian Federation is limited to the description of individual cases. Aim. To evaluate the peculiarities of management and treatment of patients with OP in the hospital register. Materials and methods. A retrospective study was carried out in Moscow hospitals Moscow City Hospital named after S.S. Yudin and Pirogov City Clinical Hospital №1 from January 2023 to September 2024. The protocol was approved by the ethical committee of the Sechenov First Moscow State Medical University (Sechenov University). The charts of patients diagnosed with OP were analyzed. Inclusion criteria: age ≥18 years, presence of 2 of 4 major criteria for OP. Patients with HIV, pregnancy, acute psychiatric conditions and severe chronic renal failure (pSCF15 ml/min/1.73 m²) were excluded. Results. Forty patients with OP were included. Consistency of diagnostic characteristics with the grand diagnostic criteria was assessed 1 of 4 grand criteria occurred in 7 (17%) cases; 2 of 4 occurred in 25 (63%) individuals, 3 of 4 in 8 (20%); complete compliance with all criteria was absent. 27 (68%) patients had ECG changes, ST segment elevation in 24 (60%), but only 3 (13%) had changes in all leads. PQ depression and pericardial friction murmur were not recorded. OP was diagnosed on the day of hospitalization in 29 (73%) patients, in 11 (27%) – on the 2nd day after CAG. Four (10%) developed acute heart failure requiring diuretics. Monotherapy with NSAIDs was used in 21 (53%) patients, combined therapy with NSAIDs + colchicine – in 6 (15%). Bacterial etiology of OP besides antibiotics also requires prescription of combination of NSAIDs/HCS + colchicine. In the discussed study, therapy with NSAIDs, GCS and colchicine was initiated only when antibiotic therapy was ineffective, which is not in accordance with clinical guidelines. The dosage of NSAIDs was in accordance with recommendations in 40% of cases, adequate dose of colchicine in 28%. Combination therapy at discharge was recommended in 21 (52.5%) cases; correct doses and timing were indicated in 18 (44%) and 7 (17.5%) patients. Conclusion. The diagnosis of OP was more often made in the first day; in the rest, the delay in diagnosis was associated with troponin elevation and ST segment elevation on ECG, which requires CAG for differential diagnosis. The main errors of treatment: incorrect doses of NSAIDs/GCS, absence of colchicine in therapy and terms of its administration in discharge epicrises, as well as absence of information about physical load limitations

The achievements in the sorghum varieties and hybrids' breeding in the ARC “Donskoy”

Sorghum is one of the most important crops in all arid tropical and subtropical regions of Africa, Asia, and Central America. In the Russian Federation, the sowing area of sorghum varied from 8.7 to 228.6 thousand ha throughout about 20 years (1999–2018). The main share (93–98%) of the sowing area of sorghum in Russia is located in the Pre-Volga region and the Southern Federal District. The Rostov Region as a part of the Southern Federal District accounts for up to 46–69% of sorghum crops (Kovtunov, 2018). The most effective way to increase productivity and product quality is to create new varieties adapted to the soil and climatic conditions of cultivation and introduce them into agricultural production. The FSBSI “Agricultural Research Center “Donskoy” developed the white-kernelled sorghum varieties “Velikan”, “Zernogradskoye 88” and “Ataman” with 5.41–5.85 t/ha of productivity not only for fodder, but also for food (starch, alcohol). The sweet sorghum varieties “Listvenit”, “Yuzhnoye” and “Feniks” with green mass productivity of 38–46 t/ha are intended for use on green fodder and silage and are characterized by intensive initial growth, lodging resistance, drought resistance, resistance to dust smut, bacteriosis and to cereal aphids. The Sudan grass varieties “Anastasiya”, “Alisa” and “Gratsiaya” developed in the Agricultural Research Center “Donskoy” are characterized by the intensive initial growth and regrowth. They are middle-ripening, drought tolerant, highly productive with 41–44 t/ha of green mass and 8.3–8.6 t/ha of dry matter. There have been developed and are being tested the promising sorghum-Sudan hybrids with 62–77 t/ha of green mass and 11.4–16.6 t/ha of dry matter obtained in mowing the aftermath
