    Background Thermogenic brown adipose tissue has never been described in birds or other non-mammalian vertebrates. Brown adipocytes in mammals are distinguished from the more common white fat adipocytes by having numerous small lipid droplets rather than a single large one, elevated numbers of mitochondria, and mitochondrial expression of the nuclear gene UCP1, the uncoupler of oxidative phosphorylation responsible for non-shivering thermogenesis. Results We have identified in vitro inductive conditions in which mesenchymal cells isolated from the embryonic chicken limb bud differentiate into avian brown adipocyte-like cells (ABALCs) with the morphological and many of the biochemical properties of terminally differentiated brown adipocytes. Avian, and as we show here, lizard species lack the gene for UCP1, although it is present in amphibian and fish species. While ABALCs are therefore not functional brown adipocytes, they are generated by a developmental pathway virtually identical to brown fat differentiation in mammals: both the common adipogenic transcription factor peroxisome proliferator-activated receptor-Ξ³ (PPARΞ³), and a coactivator of that factor specific to brown fat differentiation in mammals, PGC1Ξ±, are elevated in expression, as are mitochondrial volume and DNA. Furthermore, ABALCs induction resulted in strong transcription from a transfected mouse UCP1 promoter. Conclusion These findings strongly suggest that the brown fat differentiation pathway evolved in a common ancestor of birds and mammals and its thermogenicity was lost in the avian lineage, with the degradation of UCP1, after it separated from the mammalian lineage. Since this event occurred no later than the saurian ancestor of birds and lizards, an implication of this is that dinosaurs had neither UCP1 nor canonically thermogenic brown fat.Nadejda V Mezentseva, Jaliya S Kumaratilake and Stuart A Newma

    The pharmacological correction of the mineral composition of animal nutrition has been substantiated. The analysis of the results of studies of fodder by veterinary laboratories of theΒ Novosibirsk region for the period 2018–2019 was carried out. It has been established that in the production of animal fodder such crops as wheat, barley, oats, millet, corn, peas, and soybeans are used. Cereals make up about 85% of the compound fodder, legumes – 45%. It is noted that the mass fraction of moisture and dry matter in all types of animal fodder is within the permissible ranges of the norm. In winter cows are fed with hay, silage and mixed fodder. So protein deficiency (10.69 Β± 0.35%) occurs for milk yield above 10 kg per day. The largest amount of crude protein is contained in the meal (36.48 Β± 1.31%), the least is in silage (3.08 Β± 0.12%). Crude fat is mainly contained in the millcake (9.68 Β± 0.83%), and its minimum content is characterized by feed concentrates (0.49 Β± 0.39%). Rough forage – hay and straw are rich in fiber (27.04 Β± 0.58 and 36.87 Β± 1.29%, respectively). A low level of calcium was found in fodder such as silage and grain used for feed purposes – 2.07 Β± 0.11 and 2.22 Β± 0.21 g / kg, respectively. Potassium deficiency was detected in compound animal fodder (2.75–3.03 g / kg), which requires correction of the diet. A low phosphorus content is noted in roughage, silage, grain (0.07–0.27%). The forage obtained during the ensiling process is provided with zinc at 8.02 Β± 1.51 mg / kg, which is a low figure. The iron content in the compound feed is at an average level of supply – 40–50 mg / kg. Evaluation of the mineral composition of different types of feed showed the highest frequency of deviations in the amount of zinc – 42.5%. There are also significant fluctuations in the content of phosphorus and calcium in feed – 26.25 and 23.75%, respectively.Обоснована фармакологичСская коррСкция ΠΌΠΈΠ½Π΅Ρ€Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ состава Ρ€Π°Ρ†ΠΈΠΎΠ½ΠΎΠ² для ΠΆΠΈΠ²ΠΎΡ‚Π½Ρ‹Ρ….

    Ecological management of soil resources is an urgent task involving periodic assessment of effect of fertilizers and other anthropogenic factors on the rate and direction of organic matter transformation. Mineralization and humification of organic residues are the most important functions of the soil, which determine its fertility and are closely related to the biochemical activity of microbial communities. When using intensive agricultural technologies, it is required to timely identify potential risks of reducing soil fertility. Taking into account the biochemical nature of the processes of mineralization and humification of organic substances, it is advisable to use indicators of enzymatic activity for this purpose. Enzymes are the most important metabolites of microorganisms. When choosing enzymatic indicators for a reliable assessment of influence of natural and anthropogenic factors on the activity of mineralization and humification, we took into account large-scale and universal processes in the cycles of the main biogenic elements – carbon and nitrogen. Soil enzyme diagnostics was shown to be likely useful instrument for evaluation of natural and anthropogenic factors effect on mineralization and humification processes in sod-podzolic soils. The most informative enzymatic tests for characterization of soil biochemical status in C and N cycles were determined. Biochemical coefficient was proposed as a resulting criteria for interpretation of enzymes activity data, allowing to compare humification and mineralization activities, reveal their disbalance and control of anthropogenic impact on soils. Experimental data on the effect of nitrogen fertilizers on the activity and ratio of humification and mineralization, obtained in long-term field experiments on soddy-podzolic soils of different granulometric composition and level of fertility are presented.ЭкологичСский ΠΌΠ΅Π½Π΅Π΄ΠΆΠΌΠ΅Π½Ρ‚ ΠΏΠΎΡ‡Π²Π΅Π½Π½Ρ‹Ρ… рСсурсов – Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½Π°Ρ Π·Π°Π΄Π°Ρ‡Π°, ΠΏΡ€Π΅Π΄ΠΏΠΎΠ»Π°Π³Π°ΡŽΡ‰Π°Ρ ΠΏΠ΅Ρ€ΠΈΠΎΠ΄ΠΈΡ‡Π΅ΡΠΊΡƒΡŽ ΠΎΡ†Π΅Π½ΠΊΡƒ влияния ΡƒΠ΄ΠΎΠ±Ρ€Π΅Π½ΠΈΠΉ ΠΈ Π΄Ρ€ΡƒΠ³ΠΈΡ… Π°Π½Ρ‚Ρ€ΠΎΠΏΠΎΠ³Π΅Π½Π½Ρ‹Ρ… Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠ² Π½Π° ΡΠΊΠΎΡ€ΠΎΡΡ‚ΡŒ ΠΈ Π½Π°ΠΏΡ€Π°Π²Π»Π΅Π½Π½ΠΎΡΡ‚ΡŒ трансформации органичСского вСщСства.

    The effect of mononitrogen fertilizer system on biochemical status of high fertility Luvisol sandy loam soil was studied during five years in the field experiment. Data interpretation of enzyme diagnostics was done based on the resulting estimation criteria, which is a biochemical coefficient including four key enzymatic parameters and representing the ratio of average speeds of humification and mineralization activities in Π‘ and N cycles. Five-year application of mono nitrogen fertilizer system resulted in progressive increase of organic substances mineralization, which enhanced with nitrogen dose rising. It is ecologically advisable to fertilize the soil with the complete mineral fertilizer with the minimal doses of phosphorus and potassium. Thus, humification and mineralization processes are balanced and organic matter is saved.ВлияниС ΠΌΠΎΠ½ΠΎΠ°Π·ΠΎΡ‚Π½ΠΎΠΉ систСмы ΡƒΠ΄ΠΎΠ±Ρ€Π΅Π½ΠΈΠΉ Π½Π° биохимичСский статус Π΄Π΅Ρ€Π½ΠΎΠ²ΠΎ-подзолистой лСгкосуглинистой ΠΏΠΎΡ‡Π²Ρ‹ с высоким содСрТаниСм фосфора ΠΈ калия ΠΈΠ·ΡƒΡ‡Π°Π»ΠΈ Π² Ρ‚Π΅Ρ‡Π΅Π½ΠΈΠ΅ 5 Π»Π΅Ρ‚.

    The article presents the therapeutic efficacy of Biozinc in the treatment of cattle with serous mastitis. The authors revealed a decrease in the number of somatic cells in milk in the experimental group of cows to 170 thousand, which corresponds to the milk from a healthy animal. Cows in the experimental group showed a positive trend in milk quality. Five cows had watery milk. Positive changes in milk quality were evident 12 hours after the first injection in the form of a reduction in flake secretion from the affected quarters. Milk was watery in all cows of the experimental group by the third day, without flakes and white color. The authors note a positive trend during disease treatment by the end of the first day of treatment in both test groups. Complete recovery was noted in ten animals, which was 100%, in the experimental group, which were treated with Biozinc. Complete recovery occurred after 3.00Β±0.15 days. The therapeutic efficacy was 100%. In the control group, seven cows (70%) recovered. A hematological examination revealed a 15.52 g/l (18.1 %) increase in hemoglobin level in the experimental group of animals and a 0.88 x 1012/l (P<0.05) increase in erythrocyte count. Through serum biochemical studies, the authors found that cows with serous mastitis showed changes in such parameters as protein, bilirubin, alanine aminotransferase (ALAT), and aspartate aminotransferase (ASAT).

    A radiochemical 71Ga-71Ge experiment to determine the integral flux of neutrinos from the sun has been constructed at the Baksan Neutrino Observatory in the USSR. Measurements have begun with 30 tonnes of gallium. An additional 30 tonnes of gallium are being installed so as to perform the full experiment with a 60-tonne target. The motivation, experiment procedures, and present status of this experiment are described. Β© 1990

    The Soviet-American Gallium Experiment is the first experiment able to measure the dominant flux of low energy p-p solar neutrinos. Four extractions made during January to May 1990 from 30 tons of gallium have been counted and indicate that the flux is consistent with 0 SNU and is less than 72 SNU (68% CL) and less than 138 SNU (95% CL). This is to be compared with the flux of 132 SNU predicted by the Standard Solar Model. Β© 1991

    Multisystem inflammatory syndrome in children (MIS-C) is a new and relatively rare nosology in children associated with COVID-19 infection, which is characterized by severe multiple organ involvement and poses an immediate life threat.Objective: to analyze the clinical, laboratory and instrumental examination data of patients with MIS-C associated with COVID-19 infection, hospitalized in the Republican Infectious Diseases Hospital of the Komi Republic and the Republican Children's Clinical Hospital of the Ministry of Health of the Komi Republic from April 2020 to April 2022.Material and methods. The retrospective study included 15 patients. The diagnosis was verified according to the Guidelines of the Russian Ministry of Health (version dated July 3, 2020). The results of clinical, instrumental and laboratory examination of patients were evaluated in comparison with literature data.Results and discussion. The prevalence of MIS-C in the Komi Republic was 5.5 per 100,000 persons under 18 years of age. The majority of the study cohort were males (66.7%), the median age was 3 years. 46.7% of cases were between the ages of 8 and 14 years. At the onset of clinical manifestations, all patients had fever and gastrointestinal symptoms. In 80% of children, pathological changes of skin and mucous membranes, as well as respiratory disorders were revealed. Involvement of the cardiovascular system in the pathological process was noted in 66.7% of cases. Less frequently, the urinary tract was affected. When analyzing laboratory data, an increase in the level of inflammatory markers, as well as lymphopenia and neutrophilia, were noted. Most patients received therapy with intravenous immunoglobulin and systemic glucocorticoids, as well as anticoagulants and acetylsalicylic acid. The outcomes of the disease in most cases were favorable, in 6.7% of patients a lethal outcome was recorded.Conclusion. The analysis of cases of MIS-C illustrates the high frequency of seroconversion to the SARS-CoV-2 virus, the predominance of males compared to females (2:1 ratio), the prevalence of the age group under 4 years, the heterogeneity of clinical manifestations and generally favorable prognosis. The diversity of clinical features of COVID-19 warrants a high degree of suspicion for MIS-C, as well as the development of a predictive tool, the "MIS-C Suspicion Index".ΠœΡƒΠ»ΡŒΡ‚ΠΈΡΠΈΡΡ‚Π΅ΠΌΠ½Ρ‹ΠΉ Π²ΠΎΡΠΏΠ°Π»ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹ΠΉ синдром Ρƒ Π΄Π΅Ρ‚Π΅ΠΉ (ΠœΠ’Π‘-Π”) – новая ΠΈ ΠΎΡ‚Π½ΠΎΡΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎ рСдкая нозология Ρƒ Π΄Π΅Ρ‚Π΅ΠΉ, связанная с ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠ΅ΠΉ COVID-19, которая характСризуСтся тяТСлым ΠΏΠΎΠ»ΠΈΠΎΡ€Π³Π°Π½Π½Ρ‹ΠΌ ΠΏΠΎΡ€Π°ΠΆΠ΅Π½ΠΈΠ΅ΠΌ ΠΈ прСдставляСт Π½Π΅ΠΏΠΎΡΡ€Π΅Π΄ΡΡ‚Π²Π΅Π½Π½ΡƒΡŽ ΡƒΠ³Ρ€ΠΎΠ·Ρƒ ΠΆΠΈΠ·Π½ΠΈ.ЦСль исслСдования – Π°Π½Π°Π»ΠΈΠ· ΠΊΠ»ΠΈΠ½ΠΈΠΊΠΎ-Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹Ρ… ΠΈ ΠΈΠ½ΡΡ‚Ρ€ΡƒΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½Ρ‹Ρ… Π΄Π°Π½Π½Ρ‹Ρ… ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с ΠœΠ’Π‘-Π”, ассоциированным с ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠ΅ΠΉ COVID-19, госпитализированных Π² Π“Π‘Π£Π— РСспублики Коми «РСспубликанская инфСкционная Π±ΠΎΠ»ΡŒΠ½ΠΈΡ†Π°Β» ΠΈ Π“Π£ «РСспубликанская дСтская клиничСская Π±ΠΎΠ»ΡŒΠ½ΠΈΡ†Π°Β» ΠœΠΈΠ½Π·Π΄Ρ€Π°Π²Π° РСспублики Коми с апрСля 2020 ΠΏΠΎ Π°ΠΏΡ€Π΅Π»ΡŒ 2022 Π³.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π» ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.
