Effect of soluble factors of macrophages polarized by efferocytosis on neuronal density in the frontal cortex and hippocampus of mice in a model of stress-induced depression

Recently, there has been a steady increase in depressive disorders, which occupy an important place in the structure of the causes of disability. In the pathogenesis of depression, an important role is played by neuroinflammation, which is associated with impaired adult neurogenesis. Notably, neuroinflammation is partially reversible, and the leading role in the initiation and regulation of neuroregeneration is given to macrophages. Opposite states of macrophage activation are classically activated M1 and alternatively activated M2 macrophages, characterized, respectively, by pro- and anti-inflammatory activity. A balance shift towards M2 macrophages has been considered as a new therapeutic strategy of psycho-neurological disorders. One of the inducers of the M2 phenotype is the efferocytosis. We have previously developed an original protocol for the generation of human macrophages under conditions of deficiency of growth / serum factors, in which M2 phenotype is formed through efferocytosis. Macrophages (M2(LS), LS – Low Serum) obtained according to this protocol express M2-associated markers, and are characterized by high production of growth and pro- angiogenic factors (IGF-1, VEGF, BDNF, EGF, FGF-basic, etc.), which can suppress inflammation and stimulate neuroregeneration / neuroplasticity. In the model of stress-induced depression, the antidepressant effect of soluble factors of M2(LS) macrophages was shown, accompanied by a decrease in the level of pro- inflammatory cytokines in certain brain structures. However, the effect of M2(LS) factors on neurogenesis remained unexplored. In the present work, which is a continuation of the aforementioned study, we analyzed the effect of intranasal administration of M2(LS) soluble factors on neuronal density in different brain areas – the frontal cortex and hippocampus – of depression-like mice. The results obtained showed that neuronal density in the frontal cortex, CA1 and CA3 zones of the hippocampus, was significantly higher in mice with intranasal administration of M2(LS) conditioned medium than in depression-like mice, and reached the level of neuronal density in intact animals. These results may indicate the neuroregenerative activity of M2(LS) macrophages in the model of stress-induced depression, which is mediated through soluble factors and manifests itself in an increase in the density of neurons in the brain

Oat cultivars developed at Nemchinovka and included into the State Register in recent years (a review)

The main trend in crop breeding is to increase productivity and improve grain quality indicators. The formation of high crop productivity requires cultivars with high potential for productivity and quality as well as with resistance to biotic and abiotic environmental factors. Successful solution of these and emerging breeding problems is possible only if appropriate source material is employed.Source material from the Vavilov Institute’s collection of plant genetic resources was used in crosses aimed at the development of oat cultivars. Its brief description is presented here.The results of the breeding work on oat cultivars at the Nemchinovka Federal Research Center from 2007 through 2017 are discussed. Descriptions are given to all ten developed oat cultivars with a detailed pedigree for each combination of crosses. Pedigree analysis has been performed, and its results show a limited number of parental forms for crosses. The problem of source material utilization in breeding practice and narrowing of the genetic base in the process of cultivar development is discussed

Resistance of oat breeding lines to grain contamination with Fusarium langsethiae and T-2/HT-2 toxins

Fusarium disease of oats reduces yield quality due to decreasing germination that is caused by then contamination of grain with mycotoxins produced by Fusarium fungi. The aim of this study was to characterize the resistance of naked breeding lines of oats to fungal grain infection and to contamination with T-2 and HT-2 toxins. Thirteen naked oat breeding lines and two naked varieties, Nemchinovsky 61 and Vyatskiy, as well as a husked variety Yakov, were grown under natural conditions in the Nemchinovka Federal Research Center in 2019–2020. The contamination of grain with fungi was determined by the mycological method and real-time PCR. The analysis of mycotoxins was carried out by ELISA. In oats, Alternaria (the grain infection was 15–90 %), Cochliobolus (1–33 %), Cladosporium (1–19 %), Epicoccum (0–11 %), and Fusarium (3–17 %) fungi prevailed in the grain mycobiota. The predominant Fusarium species were F. poae (its proportion among Fusarium fungi was 49–68 %) and F. langsethiae (29–28 %). The highest amounts of F. langsethiae DNA ((27.9–71.9)×10–4 pg/ng) and T-2/HT-2 toxins (790–1230 μg/kg) were found in the grain of husked oat Yakov. Among the analysed naked oat lines, the amount of F. langsethiae DNA varied in the range of (1.2–42.7)×10–4 pg/ng, and the content of T-2/HT-2 toxins was in the range of 5–229 μg/kg. Two oat breeding lines, 54h2476 and 66h2618, as well as a new variety, Azil (57h2396), can be characterized as highly resistant to infection with Fusarium fungi and contamination with mycotoxins compared to the control variety Vyatskiy

Прогнозирование неврологического исхода у пациентов с постреанимационной болезнью

Post-cardiac arrest syndrome is an extremely complex nosology, characterized by high mortality and the development of severe neurological disorders. Predicting the neurological outcome in this pathology is an urgent problem, since it allows determining the tactics of patient management and optimizing the scope of medical care, as well as preparing the patient's family members for expected results of treatment. Currently, clinical, laboratory and instrumental data are used as predictors of an unfavorable neurological outcome (e.g., pupillary responses, neuron-specific enolase levels, electroencephalography). There is no single criterion with high sensitivity and specificity for predicting neurological disorders; therefore, a multimodal approach is required. This article discusses several factors, the combination of which allows predicting the outcome of post-cardiac arrest syndrome with the greatest degree of reliability.Постреанимационная болезнь представляет собой чрезвычайно сложный комплекс прогрессирующих изменений, развивающихся во всех системах, органах и тканях, исходы которого характеризуются высокой летальностью и развитием тяжелого неврологического дефицита. Во всем мире прогнозирование неврологического исхода при данной патологии является актуальной проблемой, так как позволяет определить тактику ведения пациента и оптимизировать объем оказания медицинской помощи, а также подготовить членов семьи больного к ожидаемым результатам лечения. В настоящее время в качестве предикторов неблагоприятного неврологического исхода используют клинические, лабораторные и инструментальные данные. Ввиду отсутствия единого критерия, обладающего высокой чувствительностью и специфичностью, прогнозирование неврологического дефицита должно основываться на мультимодальном подходе. В обзоре рассмотрен ряд клинических, лабораторных и инструментальных предикторов (зрачковые реакции, уровень нейрон-специфической енолазы, электроэнцефалография и ряд других), совокупность которых позволяет с наибольшей достоверностью прогнозировать неврологический исход постреанимационной болезни
