    Abstract The purpose of the work is to develop individual treatment regimens for children with secretory otitis media (SOM) depending on the results of an in-depth examination of them, in particular, the identification of Epstein-Barr virus (EBV), the presence of pathogenic microflora in the nasopharynx and the results of a level 1 immunogram. Laboratory examination for the presence of serological markers: IgM to the capsid complex (VCA), IgG to the early antigen (EA) and the nuclear antigen EBNA in the blood serum by enzyme-linked immunosorbent assay (ELISA). 68 children were exposed, children's department of the 30th hospital. Kharkiv during 2017-2019 with a diagnosis of secretory otitis media. The same children underwent a classic bacteriological study of the nasopharynx and level 1 immunogram. Among 68 children with secretory otitis media, a high percentage (16.2%) of infected patients with acute EBV in the acute phase and 20 children previously infected were detected. In total, out of 68 children, 31 (45.6%). In most SOM infected children with EBV, a decrease in the cellular component of immunity was revealed: a decrease in the subpopulations of T-lymphocytes from CD4 helper cells and CD16 from NK killer cells. Streptococcus pyogenes-13 (19.1%) cases prevailed in the nasopharynx in children with SOM, 2nd in frequency. H.influenza was detected in 13 cases (19.1%), Streptococcus pneumonia, the third strain, 11 strain (16.2%), and the fourth, Staplylooccus aureus, 12 strains (17.6%) were seeded 3rd in frequency. The lowest levels of immunograms were found in children infected with EBV. Immunocorrection, require and carriers of streptococci (other drugs). Therefore, the examined children, divided into 3 groups, received various immunomodulating agents: thymalin and Broncho-Vaxom (bacterial lysate), and in some cases we combined topical administration of thymalin with endaural phonophoresis followed by treatment with Broncho-Vaxom. It was these children who had the least number of relapses SOM of against the background of the best indicators of immunity.

    Abstract Fundamental neurophysiological processes are often studied using Danio rerio fish as a model. A selective inhibitor of striatal-enriched protein tyrosine phosphatase (STEP) reduces serotonin metabolism in the D. rerio brain. Both STEP and serotonin are involved in the development of neurodegenerative behavioral disorders. Reduction or elevation of the serotonin level in the brain of mice caused by the administration of p-chlorophenylalanine or pargyline, respectively, results in a decrease in the level of ptpn5 mRNA in the striatum, ptpn5 being the gene encoding STEP. However, it has not been established whether this occurs in other organisms. We studied the effect of inhibitors of synthesis (p-chlorophenylalanine) and degradation (pargyline) of serotonin on the expression of the ptpn5 gene and the activity of STEP in the brain of D. rerio. The fish were placed in water containing p-chlorophenylalanine (2 mg/L) or pargyline (0.5 mg/L) for 72 hours, and control subjects were kept in aquarium water. The p-chlorophenylalanine treatment decreased the serotonin level in the brain fourfold, whereas pargyline increased the level of this transmitter sixfold. Both p-chlorophenylalanine and pargyline decrease STEP activity in the D. rerio brain, without affecting the level of the ptpn5 mRNA gene. Thus, interaction between STEP and the serotonin system is observed in both mammals and fish, which indicates the similarity of the regulation processes in vertebrates.

    Abstract Effects of acute treatment with antidepressant drugs, imipramine and citalopram, on behavior and activity of striatal-enriched tyrosine protein phosphatase (STEP) in the whole brain of zebrafish Danio rerio were studied. Mature zebrafish were exposed for 3 h to water (control) or to solutions of 0.25, 0.5, or 1 mg/liter of imipramine or citalopram, and then their behavior was studied in novel tank test. STEP activity was assayed in the brain of animals by the difference between the rates of transformation of p-nitrophenyl phosphate to 4-nitrophenol in the absence or presence of a selective STEP inhibitor. In novel tank test, imipramine and citalopram reduced locomotor activity and increased freezing time; at this, imipramine increased the total time spent in top of the tank. Citalopram (all concentrations) and imipramine (0.5 and 1 mg/liter) increased STEP activity in zebrafish brain.

    Abstract The study of the mineralogical composition of sand (0.25–0.10 mm) and coarse silt (0.10–0.05 mm) fractions revealed a significant lithological heterogeneity of soil-forming material in the area of the Zvenigorod Biostation. The domination of ore minerals in heavy fractions (to 42% of grains) and, to a smaller rate, of hornblende and biotite, explains iron accumulation in soil profiles and the brown color of sandy loam soils. This feature, along with the insignificant presence of the clay fraction, enables us to assign texturally undifferentiated soils to the division of iron-metamorphic soils and more differentiated soils to the division of eluvial soils.

    Abstract Striatal-enriched tyrosine protein phosphatase (STEP) is expressed mainly in the brain. Its dysregulation is associated with Alzheimer's and Huntington's diseases, schizophrenia, fragile X syndrome, drug abuse and stroke/ischemia. However, an association between STEP and depressive disorders is still obscure. The review discusses the theoretical foundations and experimental facts concerning possible relationship between STEP dysregulation and depression risk. STEP dephosphorylates and inactivates several key neuronal signaling proteins such as extracellular signal-regulating kinase 1 and 2 (ERK1/2), stress activated protein kinases p38, the Src family tyrosine kinases Fyn, Pyk2, NMDA and AMPA glutamate receptors. The inactivation of these proteins decreases the expression of brain derived neurotrophic factor (BDNF) necessary for neurogenesis and neuronal survival. The deficit of BDNF results in progressive degeneration of neurons in the hippocampus and cortex and increases depression risk. At the same time, a STEP inhibitor, 8-(trifluoromethyl)-1,2,3,4,5-benzopentathiepin-6-amine hydrochloride (TC-2153), increases BDNF expression in the hippocampus and attenuated the depressivelike behavior in mice. Thus, STEP is involved in the mechanism of depressive disorders and it is a promising molecular target for atypical antidepressant drugs of new generation.

    Abstract Striatal-enriched protein tyrosine phosphatase (STEP), which was initially identified in the striatum, is encoded by the Ptpn5 gene and is expressed in neurons of various structures of the brain. STEP is involved in regulating neuroplasticity, and its expression abnormalities are associated with human neurodegenerative disorders. The STEP inhibitor 8-trifluoromethyl-1,2,3,4,5-benzopentathiepin-6-amine hydrochloride (TC-2153) has been shown to affect the serotoninergic system of the brain. However, the influence of the serotoninergic system on the STEP regulation has not been studied yet. The aim of the study was to investigate how pharmacologically induced changes in the brain serotonin (5-HT) level affect Ptpn5 expression and STEP activity in adult male C57BL/6J mice. To modulate the 5-HT level in the brain, the 5-HT synthesis inhibitor p-chlorophenylalanine or 5-HT degradation inhibitor pargyline was administered intraperitoneally for three successive days. Changes in 5-HT concentration in the brain were assayed using high-performance liquid chromatography. The STEP activity was determined spectrophotometrically in the supernatant by the rate of p-nitrophenyl phosphate dephosphorylation in the absence and presence of the selective STEP inhibitor TC-2153. The Ptpn5 mRNA level was determined using quantitative RT-PCR. The Ptpn5 expression level in the striatum was three times higher than in the cortex and hippocampus. Both increases and decreases in brain 5-HT were for the first time associated with a decrease in Ptpn5 mRNA in the striatum. STEP activity in the striatum and cortex was significantly higher than in the hippocampus. However, p-chlorophenylalanine and pargyline did not affect the STEP activity in the brain structures tested. Thus, a new method was proposed to study the STEP activity in the brain and p-chlorophenylalanine and pargyline were shown to decrease Ptpn5 expression in the striatum in mice.

    Abstract With 20% of the world's forests, Russia has global potential in bioeconomy development, biodiversity conservation and climate change mitigation. However, unsustainable forest management based on 'wood mining' reduces this potential. Based on document analysis, participant observations and interviews, this article shows how non-state actors-environmental NGOs and forest companies-address forest resource depletion and primary forest loss in Russia. We analyse two key interrelated forest discourses driven by non-state actors in Russia: (1) intensive forest management in secondary forests as a pathway towards sustained yield and primary forest conservation; (2) intact forest landscapes as a priority in primary forest conservation. We illustrate how these discourses have been integrated into policy debates, institutions and practices and discuss their relation to relevant global discourses. The article concludes that despite successful cases in conserving intact forest landscapes, there is still a frontier between sustainable forest management discourses and forestry practice in Russia.

    Abstract The organisation of even minor additional lighting on the General light background gives a noticeable effect and is the primary task of vegetable growing. The influence of different peaks of 440-450 nm and 650-660 nm of the spectrum for optimal plant growth was experimentally studied. The lack of functional mathematical models for describing the development of plants indicates the need for scientific justification of the optimal spectral composition of the photosynthetically active zone on the example of a specific culture of protected soil. The dynamics of plant height growth in various lighting options is compared: without additional artificial lighting, when using a DNAT lamp, a GLP-FH-56-B lamp, a GLP-FH-56-R lamp, a GLP-FH-56-RB lamp. The obtained functional models of growth in the first two months of vegetation with a different spectrum of additional lighting with good correlation describe power equations.

    Title translation Clinical efficacy of ct-guided transthoracic needle biopsy of peripheral lung lesions.
    Abstract Objective: To evaluate the effectiveness of a step-by-step protocol for GT-guided transthoracic biopsy in verification of peripheral lung tumors.
    Material and methods: A retrospective analysis of the results of GT-guided transthoracic biopsies of focal lung neoplasms was performed between October 2019 and December 2020. The analysis included the results of 176 biopsies in 158 patients.
    Results: Primary biopsy was informative in 139 (87.97%) out of 158 patients. There were 155 (88.07%) informative and 21 (11.93%) non-informative biopsies. Lung adenocarcinoma was diagnosed in 41 (25.95%) patients, squamous cell carcinoma in 35 (22.15%) patients, and small cell carcinoma in 9 (5.7%) patients. There were 17 (10.76%) patients with uninformative biopsy results. Sensitivity, specificity and accuracy were 86%, 95.5%, and 87.8%, respectively. PPV was 98.9%, NPV - 58.3%. Various complications occurred after 65 (36.93%) out of 176 biopsies (95% CI 30.15-44.27). Pneumothorax followed by pleural drainage was detected after 8 (4.55%) biopsies.
    Conclusion: Accuracy of a step-by-step protocol for transthoracic biopsy was 88% that is not inferior to similar results in large-scale studies devoted to specialized navigation systems.
