Abstract: Abstract Using e + e − annihilation data sets corresponding to an integrated luminosity of 4.5 fb −1, collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, we report the first measurements of the absolute branching fractions B Λ c + → p K L 0 $$ \mathcal{B}\left({\Lambda}_c^{+}\to p{K}_L^0\right) $$ = (1.67 ± 0.06 ± 0.04)%, B Λ c + → p K L 0 π + π − $$ \mathcal{B}\left({\Lambda}_c^{+}\to p{K}_L^0{\pi}^{+}{\pi}^{-}\right) $$ = (1.69 ± 0.10 ± 0.05)%, and B Λ c + → p K L 0 π 0 $$ \mathcal{B}\left({\Lambda}_c^{+}\to p{K}_L^0{\pi}^0\right) $$ = (2.02 ± 0.13 ± 0.05)%, where the first uncertainties are statistical and the second systematic. Combining with the known branching fractions of Λ c + → p K S 0 $$ {\Lambda}_c^{+}\to p{K}_S^0 $$ , Λ c + → p K S 0 π + π − $$ {\Lambda}_c^{+}\to p{K}_S^0{\pi}^{+}{\pi}^{-} $$ , and Λ c + → p K S 0 π 0 $$ {\Lambda}_c^{+}\to p{K}_S^0{\pi}^0 $$ , we present the first measurements of the K S 0 $$ {K}_S^0 $$ - K L 0 $$ {K}_L^0 $$ asymmetries R Λ c + K S , L 0 X = B Λ c + → K S 0 X − B Λ c + → K L 0 X B Λ c + → K S 0 X + B Λ c + → K L 0 X $$ R\left({\Lambda}_c^{+},{K}_{S,L}^0X\right)=\frac{\mathcal{B}\left({\Lambda}_c^{+}\to {K}_S^0X\right)-\mathcal{B}\left({\Lambda}_c^{+}\to {K}_L^0X\right)}{\mathcal{B}\left({\Lambda}_c^{+}\to {K}_S^0X\right)+\mathcal{B}\left({\Lambda}_c^{+}\to {K}_L^0X\right)} $$ in charmed baryon decays: R Λ c + p K S , L 0 = − 0.025 ± 0.031 $$ R\left({\Lambda}_c^{+},p{K}_{S,L}^0\right)=-0.025\pm 0.031 $$ , R Λ c + p K S , L 0 π + π − = − 0.027 ± 0.048 $$ R\left({\Lambda}_c^{+},p{K}_{S,L}^0{\pi}^{+}{\pi}^{-}\right)=-0.027\pm 0.048 $$ and R Λ c + p K S , L 0 π 0 = − 0.015 ± 0.046 $$ R\left({\Lambda}_c^{+},p{K}_{S,L}^0{\pi}^0\right)=-0.015\pm 0.046 $$ . No significant asymmetries with statistical significance are observed.

Abstract: Abstract The processes h c → γP (P = η′, η, π 0) are studied with a sample of (27.12 ± 0.14) × 108 ψ(3686) events collected by the BESIII detector at the BEPCII collider. The decay h c → γη is observed for the first time with the significance of 9.0 σ, and the branching fraction is determined to be (3.77 ± 0.55 ± 0.13 ± 0.26) × 10 −4, while B $$ \mathcal{B} $$ (h c → γη′) is measured to be (1.40 ± 0.11 ± 0.04 ± 0.10) × 10 −3, where the first uncertainties are statistical, the second systematic, and the third from the branching fraction of ψ(3686) → π 0 h c . The combination of these results allows for a precise determination of R h c = B h c → γη B h c → γ η ′ , $$ {R}_{h_c}=\frac{\mathcal{B}\left({h}_c\to {\pi}^0\gamma \eta \right)}{\mathcal{B}\left({h}_c\to {\pi}^0\gamma {\eta}^{\prime}\right)}, $$ which is calculated to be (27.0 ± 4.4 ± 1.0)%. The results are valuable for gaining a deeper understanding of η − η′ mixing, and its manifestation within quantum chromodynamics. No significant signal is found for the decay h c → γπ 0, and an upper limit is placed on its branching fraction of B $$ \mathcal{B} $$ (h c → γπ 0) < 5.0 × 10 −5, at the 90% confidence level.

Abstract: Abstract Using e + e − collision data collected with the BESIII detector at the BEPCII collider at center-of-mass energies between 3.510 and 4.914 GeV, corresponding to an integrated luminosity of 25 fb −1, we measure the Born cross sections for the process e + e − → K − Ξ ¯ + Λ / Σ 0 $$ {e}^{+}{e}^{-}\to {K}^{-}{\overline{\Xi}}^{+}\Lambda /{\Sigma}^0 $$ at thirty-five energy points with a partial-reconstruction strategy. By fitting the dressed cross sections of e + e − → K − Ξ ¯ + Λ / Σ 0 $$ {e}^{+}{e}^{-}\to {K}^{-}{\overline{\Xi}}^{+}\Lambda /{\Sigma}^0 $$ , evidence for ψ 4160 → K − Ξ ¯ + Λ $$ \psi (4160)\to {K}^{-}{\overline{\Xi}}^{+}\Lambda $$ is found for the first time with a significance of 4.4σ, including systematic uncertainties. No evidence for other possible resonances is found. In addition, the products of electronic partial width and branching fraction for all assumed resonances decaying into K − Ξ ¯ + Λ / Σ 0 $$ {K}^{-}{\overline{\Xi}}^{+}\Lambda /{\Sigma}^0 $$ are determined.

Abstract: Abstract With a sample of (10087 ± 44) × 106 J/ψ events accumulated with the BESIII detector, we analyze the decays η′ → π + π − l + l − (l = e, μ) via the process J/ψ → γη′. The branching fractions are measured to be B $$ \mathcal{B} $$ (η′ → π + π − e + e − ) = (2.45 ± 0.02(stat.) ± 0.08(syst.)) × 10 −3 and B $$ \mathcal{B} $$ (η′ → π + π − μ + μ − ) = (2.16 ± 0.12(stat.) ± 0.06(syst.)) × 10 −5, and the ratio is B η ′ → π + π − e + e − B η ′ → π + π − μ + μ − = 113.4 ± 0.9 stat . ± 3.7 syst . $$ \frac{\mathcal{B}\left({\eta}^{\prime}\to {\pi}^{+}{\pi}^{-}{e}^{+}{e}^{-}\right)}{\mathcal{B}\left({\eta}^{\prime}\to {\pi}^{+}{\pi}^{-}{\mu}^{+}{\mu}^{-}\right)}=113.4\pm 0.9\left(\textrm{stat}.\right)\pm 3.7\left(\textrm{syst}.\right) $$ . In addition, by combining the η′ → π + π − e + e − and η′ → π + π − μ + μ − decays, the slope parameter of the electromagnetic transition form factor is measured to be b η′ = 1.30 ± 0.19 (GeV/c 2) −2, which is consistent with previous measurements from BESIII and theoretical predictions from the VMD model. The asymmetry in the angle between the π + π − and l + l − decay planes, which has the potential to reveal the CP-violation originating from an unconventional electric dipole transition, is also investigated. The asymmetry parameters are determined to be A CP η ′ → π + π − e + e − = − 0.21 ± 0.73 stat . ± 0.01 syst . % $$ {\mathcal{A}}_{CP}\left({\eta}^{\prime}\to {\pi}^{+}{\pi}^{-}{e}^{+}{e}^{-}\right)=\left(-0.21\pm 0.73\left(\textrm{stat}.\right)\pm 0.01\left(\textrm{syst}.\right)\right)\% $$ and A CP η ′ → π + π − μ + μ − = 0.62 ± 4.71 stat . ± 0.08 syst . % $$ {\mathcal{A}}_{CP}\left({\eta}^{\prime}\to {\pi}^{+}{\pi}^{-}{\mu}^{+}{\mu}^{-}\right)=\left(0.62\pm 4.71\left(\textrm{stat}.\right)\pm 0.08\left(\textrm{syst}.\right)\right)\% $$ , implying that no evidence of CP-violation is observed at the present statistics. Finally, an axion-like particle is searched for via the decay η′ → π + π − a, a → e + e − , and upper limits of the branching fractions are presented for the mass assumptions of the axion-like particle in the range of 0 − 500 MeV/c 2.

Abstract: Abstract We measured the Born cross sections for the process e + e − → ωη′ at 22 center-of-mass energies from 2.000 to 3.080 GeV with the BESIII detector at the BEPCII collider. We observed a resonant structure with a statistical significance of 9.6σ. A Breit-Wigner fit determines its mass to be M R = (2153 ± 30 ± 31) MeV/c 2 and its width to be Γ R = (167 ± 77 ± 7) MeV, where the first uncertainties are statistical and the second are systematic.

Abstract: Abstract Using e + e − collision data collected at the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity of 7.33 fb −1, we determine the absolute branching fractions of fifteen hadronic D s + $$ {D}_s^{+} $$ decays with a double-tag technique. In particular, we make precise measurements of the branching fractions B D s + → K + K − π + = 5.49 ± 0.04 ± 0.07 % $$ \mathcal{B}\left({D}_s^{+}\to {K}^{+}{K}^{-}{\pi}^{+}\right)=\left(5.49\pm 0.04\pm 0.07\right)\% $$ , B D s + → K S 0 K + = 1.50 ± 0.01 ± 0.01 % $$ \mathcal{B}\left({D}_s^{+}\to {K}_S^0{K}^{+}\right)=\left(1.50\pm 0.01\pm 0.01\right)\% $$ and B D s + → K + K − π + π 0 = 5.50 ± 0.05 ± 0.11 % $$ \mathcal{B}\left({D}_s^{+}\to {K}^{+}{K}^{-}{\pi}^{+}{\pi}^0\right)=\left(5.50\pm 0.05\pm 0.11\right)\% $$ , where the first uncertainties are statistical and the second ones are systematic. The CP asymmetries in these decays are also measured and all are found to be compatible with zero.

Abstract: One of the primary theories regarding the development of schizophrenia revolves around genetics, indicating the involvement of hereditary factors in various processes, including inflammation. Research has demonstrated that inflammatory reactions occurring in microglia can impact the progression of the disease. It has also been established that genetically determined changes in IL-1 can contribute to schizophrenia, thereby confirming the role of the IL-1 gene cluster in disease susceptibility. The aim of this study is a computer-based assessment of the structural interactions of IL-1 proteins with their receptors in schizophrenia. The study utilized the DisGeNET database, enabling the assessment of the reliability of identified IL-1 polymorphisms. Polymorphisms were also sought using NCBI PubMed. The NCBI Protein service was employed to search for and analyze the position of the identified polymorphisms on the chromosome. Structures for modeling were extracted from the Protein Data Bank database. Protein modeling was conducted using the SWISS-MODEL server, and protein interaction modeling was performed using PRISM. Notably, this study represents the first prediction of the interactions of IL-1α, IL-1β, and IL- 1RA proteins, taking into account the presence of single-nucleotide polymorphisms associated with schizophrenia in the sequence of the corresponding genes. The results indicate that the presence of SNP rs315952 in the IL-1RA protein gene, associated with schizophrenia, may lead to a weakening of the IL-1RA binding to receptors, potentially triggering the initiation of the IL-1 signaling pathway by disrupting or weakening the IL-1RA binding to receptors and facilitating the binding of IL-1 to them. Such alterations could potentially lead to a change in the immune response. The data obtained contribute theoretically to the development of ideas about the molecular mechanisms through which hereditary factors in schizophrenia influence the interactions of proteins of the IL-1 family, which play an important role in the processes of the immune system.

Abstract: Abstract Using 24.1 fb −1 of e + e − collision data collected with the BESIII detector at the BEPCII collider, the Born cross sections and effective form factors of the e + e − → Σ + Σ ¯ − $$ {e}^{+}{e}^{-}\to {\Sigma}^{+}{\overline{\Sigma}}^{-} $$ reaction are measured. The measurements are performed at center-of-mass energies ranging from 3.510 to 4.951 GeV. No significant evidence for the decay of the charmonium(-like) states, ψ(3770), ψ(4040), ψ(4160), Y(4230), Y(4360), ψ(4415), and Y(4660), into a Σ + Σ ¯ − $$ {\Sigma}^{+}{\overline{\Sigma}}^{-} $$ final state is observed. Consequently, upper limits for the products of the branching fractions and the electronic partial widths at the 90% confidence level are reported for these decays.

10. The stress level of future teachers depending on the direction of professional subject training

Author: N. Yu. Galoy
Subjects: stress, mental tension, student, future teacher, foreign language teacher, physical education teacher, music teacher, university educational environment, primary professionalisation, psn-25, Sociology (General), HM401-1281, Economics as a science, HB71-74
Abstract: The article describes the influence of university educational environment on the formation of resistance to stress in future teachers. A theoretical analysis of the phenomenon of psychological stress as a state of mental tension manifested in emotional, behavioural and somatic sensations is presented. The results of testing 529 students, who were examined in April 2022, using the PSN-25 methodology were analysed. The features of the stress level of future teachers are formulated and statistically substantiated, depending on the direction of professional subject training (foreign language, music, physical education), course of study, gender. It was found that more than half of all respondents do not experience excessive mental stress. The number of students with a low level of stress increases from the first year to the third one, regardless of the direction of professional subject training. Among future foreign language teachers, a relatively higher level of mental stress prevails. This trend is statistically significant for the first-year students of the sample. Future of physical education and music teachers are more normalised in terms of mental stress which may be due to the peculiarities of educational environment of these faculties and due to the nature of educational and professional activities. Significant gender differences in the prevalence of higher stress levels in young ladies compared to young men were revealed in a sample of these two directions of training.

Abstract: Aim. To evaluate the usage of antihypertensive drugs (AHDs) and their combinations in participants aged 35 to74 years with arterial hypertension (AH) in the population-based study ESSE-RF3.Material and methods. Representative samples of the population aged 35 to 74 years from 15 regions of Russia (n=28731) with a response rate over 70% were examined in the ESSE-RF3 study. Therapy received by 9944 participants with AH (with systolic BP ≥140 mm Hg and/or diastolic BP ≥90 mm Hg, or when the subject was taking AHDs) was analyzed. Information about AHDs intake (brand name of the drug) was recorded by questionnaire and coded according to International Nonproprietary Names by classes. Statistical analysis was performed using the open-source R 4.1 environment. Comparison of discrete indicators between groups was performed using Fisher’s exact test. The significance level for all tested hypotheses was taken as.05. The study was approved by the Ethics Committee of FGBI “NMRC TPM” of the Ministry of Health of the Russian Federation, each participant signed an informed consent.Results. Among the patients receiving therapy for AH, angiotensin-converting enzyme inhibitors (ACEIs) were used by 38.8% of participants, angiotensin receptor blockers (ARBs) — 31.6%, betablockers (BBs) — 29.0%, сalcium channel blockers (CCBs) — 21.5%, diuretics — 18.6%, 1.1% — outdated AHDs; 8.6% — other groups of drugs. Monotherapy was used by 53.1% of patients, 33.1% of participants received two, and 13.9% received three AHDs. Among participants taking two or more AHDs (including single-pill combinations (SPC)), males most often received the combination of BB+ ACEI and females — BB+ARBs. SPC AHDs were used by 10.3% of those receiving therapy (males: 9.8%, females: 10.6%). Among SPCs, the top three combinations were CCBs + ACEIs (28%), diuretics + ACEIs (27.5%), and diuretics + ARBs (24.4%).Conclusion. The population study ESSE-RF3, based on the survey of a representative sample of the Russian population aged 35-74 years, showed that more than a half of participants with AH receiving therapy were used the monotherapy, only every tenth of those treated received SPC. The problem of insufficient patients’ literacy was indicated — about 1% of patients received outdated AGPs. In addition, 8.6% of patients used non-AHDs for the treatment of AH. For improving the control of AH treatment, it is necessary to increase the adherence of patients to the prescribed therapy and more strict adherence of doctors to the published guidelines for AH treatment.

13. Manifestation of agronomically valuable traits in the progeny of a sorghum mutant carrying the genetic construct for RNA silencing of the γ-kafirin gene

Abstract: Improving the nutritional value of grain sorghum, a drought- and heat-tolerant grain crop, is an important task in the context of global warming. One of the reasons for the low nutritional value of sorghum grain is the resistance of its storage proteins (kafirins) to proteolytic digestion, which is due, among other things, to the structural organization of protein bodies, in which γ-kafirin, the most resistant to proteases, is located on the periphery, encapsulating more easily digested α-kafirins. The introduction of genetic constructs capable of inducing RNA silencing of the γ-kafirin (gKAF1) gene opens up prospects for solving this problem. Using Agrobacterium-mediated genetic transformation of immature embryos of the grain sorghum cv. Avans we have obtained a mutant with improved digestibility of endosperm proteins (up to 92 %) carrying a genetic construct for RNA silencing of the gKAF1 gene. The goal of this work was to study the stability of inheritance of the introduced genetic construct in T2–T4 generations, to identify the number of its copies, as well as to trace the manifestation of agronomically valuable traits in the offspring of the mutant. The mutant lines were grown in experimental plots in three randomized blocks. The studied lines were characterized by improved digestibility of kafirins, a modified type of endosperm, completely or partially devoid of the vitreous layer, an increased percentage of lysine (by 75 %), reduced plant height, peduncle length, 1000-grains weight, and grain yield from the panicle. In T2, a line with monogenic control of GA resistance was selected. qPCR analysis showed that in different T3 and T4 plants, the genetic construct was present in 2–4 copies. In T3, a line with a high digestibility of endosperm proteins (81 %) and a minimal decrease in agronomically valuable traits (by 5–7 %) was selected.

Abstract: Abstract Based on e + e − collision data collected at center-of-mass energies from 2.000 to 3.080 GeV by the BESIII detector at the BEPCII collider, a partial wave analysis is performed for the process e + e − → K S 0 K L 0 $$ {K}_S^0{K}_L^0 $$ π 0. The results allow the Born cross sections of the process e + e − → K S 0 K L 0 $$ {K}_S^0{K}_L^0 $$ π 0, as well as its subprocesses e + e − → K ∗(892)0 K ¯ $$ \overline{K} $$ 0 and K 2 ∗ $$ {K}_2^{\ast } $$ (1430)0 K ¯ $$ \overline{K} $$ 0 to be measured. The Born cross sections for e + e − → K S 0 K L 0 $$ {K}_S^0{K}_L^0 $$ π 0 are consistent with previous measurements by BaBar, but with substantially improved precision. The Born cross section lineshape of the process e + e − K ∗(892)0 K ¯ $$ \overline{K} $$ 0 is consistent with a vector meson state around 2.2 GeV with a significance of 3.2σ. A Breit-Wigner fit determines its mass as M Y = (2164.7 ± 9.1 ± 3.1) MeV/c 2 and its width as Γ Y = (32.4 ± 21.0 ± 1.8) MeV.

Abstract: Abstract Using (10087 ± 44) × 106 J/ψ events collected with the BESIII detector at the BEPCII e + e − storage ring at the center-of-mass energy of s $$ \sqrt{s} $$ = 3.097 GeV, we present a search for the rare semi-muonic charmonium decay J/ψ → D − μ + ν μ + c.c.. Since no significant signal is observed, we set an upper limit of the branching fraction to be B $$ \mathcal{B} $$ (J/ψ → D − μ + ν μ + c.c.) < 5.6 × 10 −7 at 90% confidence level. This is the first search for the weak decay of charmonium with a muon in the final state.

16. Development of an Isoline Modeling Method for Extended Small Celestial Objects

Author: A. O. Andreev, Yu. A. Nefedyev, and N. Yu. Demina
Subjects: isoline modeling, extended celestial object, cometary system, Mathematics, QA1-939
Abstract: This article presents a method for modeling extended small celestial (ESC) objects, which are mainly cometary systems. Special attention was given to the possibility of analyzing their structure and physical properties in line with the modern theories of the Solar System’s formation suggesting a rather complicated evolutionary dynamics. Modeling and investigating the structure of different extended celestial objects advance our understanding of the general evolutionary processes that have taken place in the Solar System because all its objects are evolutionarily related. The isoline modeling (IM) method was tested on the real comet data and proved effective in assessing the activity of the processes that occur as ESC objects move in space. The IM method is particularly useful for studying long-period comets that, in many cases, cross the perihelion only once within a foreseeable period of human existence.

18. Experimental studies of shell and tube heat exchanger with cylindrical flow turbulators

Author: N. Yu. Nikulin and Yu. V. Elistratova
Subjects: heat exchanger, shell-and-tube, turbulization, coolant, heat transfer coefficient, heat supply, turbulator, experiment, Architecture, NA1-9428, Construction industry, HD9715-9717.5
Abstract: Introduction. Heat exchangers are important equipment in modern heat supply. This equipment is very common. Modernization of shell-and-tube heat exchangers is an important direction. The purpose of modernization is to increase the heat transfer coefficient. A heat exchanger which tubes are equipped with plates was developed. Cylindrical turbulators (ribs) are located on the plates. The experiment is important for the development of a new heat exchanger. The experimental conditions correspond to the real heat supply system.Materials and methods. The full-scale stand was used for the experiment. The stand represents an independent heating system of the building. The planning of the experiment is based on the temperature schedule of the boiler house and the temperature schedule for the consumer. Mathematical processing of the results was carried out.Results. For a heat exchanger (with turbulators), the values of the heat transfer coefficient were obtained at different outdoor temperatures during the heating period. The dependences of the heat transfer coefficient on the temperature difference are obtained. This was done at coolant velocities in the annular space of 0.16 and 0.32 m/s. Discrepancies are adequate, statistically significantly describe the results of the experiment. The heat transfer coefficient of the heat exchanger (with turbulators) turned out to be greater than that of the serial one. This parameter is 22 % more at a speed of 0.16 m/s, 23 % more at a speed of 0.32 m/s on average for the heating period.Conclusions. The heat transfer coefficient increased for the heat exchanger with turbulators by an average of 23 %. The turbulence of the coolant affects this increase. The dimensions will be much smaller for such a heat exchanger than for an apparatus with smooth tubes. Tube with cylindrical turbulators is recommended for use in different equipment. This can be used in shell-and-tube heat exchangers, air heaters, heaters, economizers.

19. Emerging trends in the construction market under increasing sanctions pressure

Author: N. Yu. Yaskova and L. I. Zaitseva
Subjects: construction market, settlement concept, forms of spatial development, spatial-territorial development, growth points, acceleration tasks, types of capital construction projects, preventive and extrajudicial methods of resolving economic disputes, Architecture, NA1-9428, Construction industry, HD9715-9717.5
Abstract: Introduction. The geopolitical and economic agenda for Russia’s economic sovereignty has required significant changes in the modes of production and, consequently, in the economic environment. The construction market is an extremely important and integral part of it in the conditions of increasing sanctions pressure. The analysis of the SMO period has convincingly proved the viability of market rules of business turnover in the investment and construction sector. None of its segments turned out to be in crisis and depression.Materials and methods. Business activity grew frontally. Meanwhile, the observed time compression of the emergence of new growing external challenges, which revealed and made it possible to identify latent processes slowing down the modernization of the construction industry, prompted the authors to change the generally accepted perspective of studying the construction market from the use of the method of decomposition of its segments to the implementation of the methodological approach of “time management in restructured space” in order to complement the megapolis concept of settlement with the strategy of accelerated development of territories in the points and corridors of economic.Results. The synthesized objectives of total acceleration of territorial, project, subject and resource maneuvering allowed to identify goals and objectives of transformation of commodity-money relations emerging within the construction market in the context of the selected types of capital construction. In this context, the authors have identified and disclosed the content of the following tasks of construction market development: providing spatial and temporal maneuverability of production capacities of market entities; synchronization and scaling of investment and construction processes; reshoring and technological import substitution; unfinished construction liquidation; supporting development rates of socially-oriented segment of construction market. Solving these tasks will require territorial, project, subject and resource front-end maneuvering. As practice has shown, this is impossible without institutionalization of a new toolkit of spatial-territorial development. Its goal is to fully realize the country’s geospatial advantage by mitigating the risks of the megacity concept of settlement, while simultaneously developing territories not only at points, but also along major spatial corridors of economic growth.Conclusions. The article took into account approaches to accelerate the commissioning of various types of capital construction projects, which allowed the study to identify the directions of improving market mechanisms across different ССP. The unity of different directions is ensured by preventive methods of avoiding the conflict of economic interests, and the resolution of inevitably arising contradictions of development is proposed using methods of extrajudicial resolution of economic disputes, based on the use of spatial-territorial, legal, judicial, cost, construction and technical, environmental expertise.

Abstract: Abstract The D s + → K + K − μ + ν μ $$ {D}_s^{+}\to {K}^{+}{K}^{-}{\mu}^{+}{\nu}_{\mu } $$ decay is studied based on 7.33 fb −1 of e + e − collision data collected with the BESIII detector at center-of-mass energies in the range from 4.128 to 4.226 GeV. The absolute branching fraction is measured as B D s + → ϕ μ + ν μ = 2.25 ± 0.09 ± 0.07 × 10 − 2 $$ \mathcal{B}\left({D}_s^{+}\to \phi {\mu}^{+}{\nu}_{\mu}\right)=\left(2.25\pm 0.09\pm 0.07\right)\times {10}^{-2} $$ , the most precise measurement to date. Combining with the world average of B D s + → ϕ e + ν e $$ \mathcal{B}\left({D}_s^{+}\to \phi {e}^{+}{\nu}_e\right) $$ , the ratio of the branching fractions obtained is B D s + → ϕ μ + ν μ B D s + → ϕ e + ν e = 0.94 ± 0.08 $$ \frac{\mathcal{B}\left({D}_s^{+}\to \phi {\mu}^{+}{\nu}_{\mu}\right)}{\mathcal{B}\left({D}_s^{+}\to \phi {e}^{+}{\nu}_e\right)}=0.94\pm 0.08 $$ , in agreement with lepton universality. By performing a partial wave analysis, the hadronic form factor ratios at q 2 = 0 are extracted, finding r V = V 0 A 1 0 = 1.58 ± 0.17 ± 0.02 $$ {r}_V=\frac{V(0)}{A_1(0)}=1.58\pm 0.17\pm 0.02 $$ and r 2 = A 2 0 A 1 0 = 0.71 ± 0.14 ± 0.02 $$ {r}_2=\frac{A_2(0)}{A_1(0)}=0.71\pm 0.14\pm 0.02 $$ , where the first uncertainties are statistical and the second are systematic. No significant S-wave contribution from f 0(980) → K + K − is found. The upper limit B D s + → f 0 980 μ + ν μ ⋅ B f 0 980 → K + K − < 5.45 × 10 − 4 $$ \mathcal{B}\left({D}_s^{+}\to {f}_0(980){\mu}^{+}{\nu}_{\mu}\right)\cdot \mathcal{B}\left({f}_0(980)\to {K}^{+}{K}^{-}\right)

Abstract: Abstract Using e + e − collision datasets corresponding to a total integrated luminosity of 21.7 fb −1 collected with the BESIII detector at the BEPCII collider at center-of-mass energies ranging from 4.009 GeV to 4.951 GeV, the energy-dependent cross sections of e + e − → p K − Λ ¯ + c . c . $$ {e}^{+}{e}^{-}\to p{K}^{-}\overline{\Lambda}+c.c. $$ are measured for the first time. By fitting these energy-dependent cross sections, we search for the excited ψ states ψ(4160) and ψ(4415), and the vector charmonium-like states ψ(4230), ψ(4360), and ψ(4660). No evidence for these is observed and the upper limits on the branching fractions of these states decaying into p K − Λ ¯ + c . c . $$ p{K}^{-}\overline{\Lambda}+c.c. $$ are set at the 90% confidence level.

Author: N. Yu. Kirillova, A. B. Ruchin, A. A. Kirillov, I. V. Chikhlyaev and M. A. Alpeev
Subjects: parasitic worms, vertebrate animals, helminth biodiversity, mordovia nature reserve, Environmental effects of industries and plants, TD194-195, Science (General), Q1-390
Abstract: In this study, we summarized our own and literature data on the helminth fauna in amphibians, reptiles, birds, and mammals inhabiting the Mordovia Nature Reserve (European Russia). The history of research on parasitic worms in vertebrates has more than 70 years here. Nowadays, 242 species of helminths have been identified in vertebrates in this protected area: 54 cestodes, 87 trematodes, 98 nematodes, and 3 acanthocephalans. Of these, 169 helminth species have an indirect life cycle, while 73 develop directly. 217 revealed parasite species use vertebrates as definitive hosts and 21 as intermediate and/or parathenic hosts. Three species of trematodes, Gorgoderina vitelliloba, Haplometra cylindracea, and Opisthioglyphe ranae combine the larval and mature lifestyle stages in amphibians. The most diverse helminth fauna is in rodents (41 species), birds (38), artiodactyls (37), and insectivores (35). Less rich in amphibians (32), bats (32), reptiles (26), and carnivores (19). Only six parasite species are found in hares. Most of the helminth species recorded in the vertebrates of the Mordovia Nature Reserve belong to the Palearctic faunistic complex – 107 species. Fifty-eight species are cosmopolitan. The range of 39 species covers the Holarctic. The distribution of 37 species of helminths is limited to Europe. Seventy-three of 242 species found in the nature reserve’s vertebrates have medical and veterinary importance as potential pathogens of dangerous zoonoses.

Subjects: cystic fibrosis, diabetes mellitus, lung function, fev1, complications, microbiological status, Nutritional diseases. Deficiency diseases, RC620-627
Abstract: BACKGROUND: In recent decades, the life expectancy of patients with CF has increased, which leads to an increase in the frequency of conditions associated with impaired carbohydrate metabolism.AIM: to analyze the impact of cystic fibrosis-associated diabetes mellitus (CFDM) in children and adolescents on the course of cystic fibrosis according to the 2021 register of patients with cystic fibrosis of the Russian Federation (RF).MATERIALS AND METHODS: the data of the register of patients with cystic fibrosis of the Russian Federation for 2021 were analyzed. The study included 122 patients with diabetes mellitus requiring the use of insulin — 33 children (27%) and 89 adults (73%), the average age of children was 13.5±4.1, the average age of adult.patients aged 18 years and older was 27.4±6.6. To compare the course of cystic fibrosis in patients with and without diabetes mellitus, groups were formed that were comparable in age, gender, genotype — the group of patients without diabetes included 827 patients, 33 patients made up the group of patients with CFRD using insulin. Diagnostic criteria, indicators of respiratory function, microbiological status, nature of complications, volume of therapy were compared.RESULTS: Patients with CFRD have a lower FEV1 compared to children without diabetes mellitus — M±SD FEV1 (%) 85.2±27.5 in the group of patients without diabetes mellitus and M±SD FEV1 (%) 72.4±26.0 in patients with diabetes mellitus (p < 0.016), compared in the microbiological seeding groups — a trend towards more frequent chronic growth of Pseudomonas aeruginosa 54.50% versus 39.4% in the group without CFRD. An increase in MRSA was also more often detected — 9.1% compared with the group of children without diabetes — 3.1%. Antibacterial therapy is more commonly used — inhaled in 54.6% of patients without diabetes mellitus while children with CFRD received inhaled antibiotic therapy in 75.8% (p=0.017). There was a significant difference in the used antibacterial tablet therapy (p=0.013). A significant difference in the number of patients on oxygen therapy in the group with CFRD — 12.1%, versus 3.4% without CFRD (p=0.01) confirms a more severe course of cystic fibrosis in patients with CFRD.CONCLUSION: The prevalence of CFDM with the need for insulin therapy among children in the Russian Federation is 1.3%. Cystic fibrosis-associated diabetes mellitus significantly worsens the course of cystic fibrosis in terms of lung function, the growth of gram-negative and resistant flora, the presence of severe complications and the frequent use of antibiotic therapy, which is obviously associated with frequent exacerbations of the bronchopulmonary process in cystic fibrosis in patients with developed cystic fibrosis-associated diabetes mellitus.

24. Experience in Using Breast Single-Photon Emission Computed Tomography with 99mTc-MIBI

Author: S. P. Shevkina, S. I. Zhestovskaya, V. V. Vyazmin, and N. Yu. Shumilina
Subjects: breast cancer, metastatic breast cancer, single-photon emission computed tomography, mammoscintigraphy, mammography, ultrasound, Medical physics. Medical radiology. Nuclear medicine, R895-920
Abstract: Objective: evaluation of the results of single-photon emission computed tomography (SPECT) with technetium-99m-methoxyisobutylisonitrile (99mTc-MIBI) in women with breast masses according to mammography (MMG) and ultrasound (US) examination in comparison with the results of morphology analysis.Material and methods. SPECT with 99mTc-MIBI was performed in 11 women aged from 30 to 63 years (median age 40 [33.5; 46.5]) with BI-RADS (Breast Imaging Reporting and Data System) categories 4 or 5 mammary masses according to bilateral MMG and US diagnostics. Two patients underwent repeated SPECT and US to analyze the primary tumor response to neoadjuvant chemotherapy.Results. With a multimodal approach to the diagnosis of breast tumors, including MMG and US, 11 pathological masses were identified. SPECT made it possible to find an additional mass that had not been previously visualized. All 12 masses were subsequently verified morphologically. With benign changes, hyperfixation of 99mTc-MIBI was not observed. SPECT allowed to assess the accumulation of the radiopharmaceutical in metastatically affected lymph nodes. However, the most sensitive method for detecting the axillary lymph node lesions is US. According to the results of repeated SPECT in 2 patients, no radiopharmaceutical accumulation was noted in mammary gland masses after two courses of neoadjuvant chemotherapy, but according to the histological examination, the tumor response was different: I and IV degrees of pathomorphosis according to G.A. LavnikovaConclusion. The experience of using mammary SPECT with 99mTc-MIBI confirms an increase in the accuracy of radiologic diagnosis of newly identified breast cancer, expands the possibilities of examination in cases of ambiguous MMG and US data, as well as the contraindications or patient’s refusal from magnetic resonance imaging.

Subjects: cardiovascular prevention, risk factors, dyslipidemia, hypercholesterolemia, esse-rf3, Therapeutics. Pharmacology, RM1-950, Diseases of the circulatory (Cardiovascular) system, RC666-701
Abstract: Aim. To study the gender and age characteristics of dyslipidemia in the population of the Nizhny Novgorod region.Material and methods. A total of 2501 people aged 35-74 among the population of the Nizhny Novgorod region were examined, selected by stratified multi-stage random sampling. The study was performed as part of the third epidemiological study ESSE-RF3. All respondents underwent an anthropometric survey, a questionnaire to identify chronic non-communicable diseases and related risk factors. The following laboratory tests were performed: total cholesterol (TC), low-density lipoproteins (LDL-C), high-density lipoproteins (HDL-C), triglycerides (TG). Among the entire cohort of patients at the time of blood sampling, 276 people (11,0%) were receiving lipid-lowering drugs. They were excluded from further analysis. Hypercholesterolemia (HCL) was recorded with a total cholesterol ≥5,0 mmol/l, an increased level of LDL-C — with a level ≥3,0 mmol/l, hypertriglyceridemia (HTG) — with a TG ≥1,7 mmol/l, a reduced level of HDL-C — with a level in males ≤1,0 mmol/l, in women ≤1,2 mmol/l.Results. The prevalence of HCL was 65,1%. In the young cohort (40-44 years), men were significantly more likely to have hypercholesterolemia, but in the middle (50-54 years) and older (60 years or more) age groups, this lipid metabolism disorder was observed with greater frequency among females. In addition, 68,9% of the respondents had elevated LDL-C levels. When studying the prevalence of this type of dyslipidemia in different age groups among men and women, a similar trend can be noted with similar TC values, but significant gender differences in the prevalence of elevated LDL-C levels l were revealed only in the 60-64 and 65-69 years groups. The prevalence of HTG among the adult population of the Nizhny Novgorod region was 42,6%. Among the 35-49 years and 55-59 years age groups, the prevalence of elevated TG levels was significantly more common among men. The incidence of decreased HDL-C levels was 13,3%. This type of dyslipidemia was significantly more often detected among men only in the youngest subgroup (35-39 years).Conclusion. Among the population of the Nizhny Novgorod region, hypercholesterolemia occurred in 65,1% of respondents, an increased level of LDL-C — in 68,9%, a HTG — in 42,6%, a reduced level of HDL-C — in 13,3%. The data obtained determine a high cardiovascular risk and require the development of prevention and treatment measures for lipid metabolism disorders.

Abstract: Abstract Using e + e − collision data corresponding to a total integrated luminosity of 12.9 fb −1 collected with the BESIII detector at the BEPCII collider, the exclusive Born cross sections and the effective form factors of the reaction e + e − → Ξ − Ξ ¯ + $$ {e}^{+}{e}^{-}\to {\Xi}^{-}{\overline{\Xi}}^{+} $$ are measured via the single baryon-tag method at 23 center-of-mass energies between 3.510 and 4.843 GeV. Evidence for the decay ψ 3770 → Ξ − Ξ ¯ + $$ \psi (3770)\to {\Xi}^{-}{\overline{\Xi}}^{+} $$ is observed with a significance of 4.5σ by analyzing the measured cross sections together with earlier BESIII results. For the other charmonium(-like) states ψ(4040), ψ(4160), Y(4230), Y(4360), ψ(4415), and Y(4660), no significant signal of their decay to Ξ − Ξ ¯ + $$ {\Xi}^{-}{\overline{\Xi}}^{+} $$ is found. For these states, upper limits of the products of the branching fraction and the electronic partial width at the 90% confidence level are provided.

Abstract: Abstract Based on 4.5 fb −1 e + e − collision data collected with BESIII detector at seven energy points between 4.600 and 4.699 GeV, the branching fractions for Λ c + → pη $$ {\Lambda}_c^{+}\to p\eta $$ and Λ c + → pω $$ {\Lambda}_c^{+}\to p\omega $$ were measured by means of single-tag method. The branching fractions of Λ c + → pη $$ {\Lambda}_c^{+}\to p\eta $$ and Λ c + → pω $$ {\Lambda}_c^{+}\to p\omega $$ are determined to be (1.57 ± 0.11stat ± 0.04syst) × 10 −3 and (1.11 ± 0.20stat ± 0.07syst) × 10 −3, with a statistical significance of greater than 10σ and 5.7σ, respectively. These results are consistent with the previous measurements by BESIII, LHCb and Belle, and the result of Λ c + → pη $$ {\Lambda}_c^{+}\to p\eta $$ is the most precise to date.

Abstract: This article reports the results of our study aimed at synthesizing and describing the structure and properties of new transition metal complexes with potential anti-tuberculosis and other related activities. For the first time, five bis-complexes of the ligand N’-(1-(6-methylpyridine-2-yl)ethylidene)isonicotinohydrazide (LH) with ions of five 3d metals (Cu(II), Mn(II), Co(II), Ni(II), and Zn(II)) were synthesized. The structures of all synthesized complexes in crystalline form were identified by X-ray diffraction (XRD) analysis. The resulting compounds were characterized by NMR, mass spectrometry, and electron spectroscopy. DFT/PCM calculations were performed on the structures of the five ML(OH) hydroxocomplexes formed during the hydrolysis of ML2 complexes in an aqueous medium within the physiological pH range. The binding energies of the ML(OH) complexes with the biotarget, the InhA protein of the Mycobacterium tuberculosis strain, were determined by molecular docking. The data obtained suggest that the studied complexes have high biological activity and warrant further biomedical research.

Subjects: diabetes mellitus, menopause, osteoporosis, bone remodeling, Physiology, QP1-981, Biochemistry, QD415-436
Abstract: BACKGROUND: Osteoporosis is metabolic skeletal disease characterized with low bone mass, bone microarchitecture disturbance that together lead to high prevalence of fragility fractures. Postmenopausal osteoporosis accounts for about 80% of the osteoporosis structure in women over 50 years. Diabetes mellitus (DM) is an independent risk factor for low-traumatic fractures. The incidence of both type 2 DM and osteoporosis increases during menopause. Therefore, the study of bone metabolism in experimental diabetes and surgical menopause seems important.THE AIM of the study was to investigate bone metabolism parameters during menopause and experimental type 2 DM.MATERIALS AND METHODS: The half of female Wistar rats had been subjected to bilateral ovariectomy at the beginning of the experiment. Diabetes mellitus (DM) was modelled using a high-fat diet and streptozotocin+nicotinamide. Four weeks after the following groups were formed: «Сontrol» (females without any interventions receiving standard chew, n=5) «OE» (females after ovariectomy n=5), «DM» (females with DM, n=4), «OE+DM» (females after ovariectomy with DM, n=4). The observation period lasted 8 weeks. Bone turnover and calcium-phosphorus metabolism markers (osteocalcin, osteoprotegerin (OPG), nuclear factor-kappa-beta receptor activator ligand (RANKL), sclerostin, fibroblast growth factor-23 (FGF-23), calcium, phosphorus) were measured in the end of experiment. Bone histomorphometry was performed after euthanasia.RESULTS: Phosphorus level was significantly lower both in the «OE» group (1.63 [1.58; 1.65] mmol/L) and in the «DM» group (2.81 [2.57; 2.83] mmol /l) compared to the «Control» group (3.12 [2.55; 3.24] mmol/l) (p

Subjects: job crafting, training, self-development, personnel, involvement, motivation, organization, employees, efficiency, Sociology (General), HM401-1281, Economics as a science, HB71-74
Abstract: The subject of the research in the article is the tools of motivation and involvement of personnel in the organization. The study examines the theoretical aspects of motivation and involvement of personnel, determines the relevance of self-development of the employees’ potential of modern organizations. The development perspective of personnel basic skills in the 21st century is shown, which includes, in addition to the traditionally necessary professional hard skills and soft skills, also existential skills containing the ability to self-development and self-learning. The concept of job crafting as a tool for staff self-development is proposed, the main idea of which is that in order for an employee to be involved in the workflow, it is necessary to reconsider the attitude to work according to the following criteria: the approach to completing tasks, the nature of interactions with colleagues, thinking when doing work. A comparative analysis of job crafting and the concept of kaizen (which is used when an organization needs changes to increase competitiveness) is carried out. Job crafting is relevant as a motivational tool when employees initiate changes themselves and form their own working environment in such a way that it meets their individual needs by adjusting the prevailing requirements of work and resources.

Subjects: introduction, naturalization, spontaneous flora, phytoinvasions, Forestry, SD1-669.5
Abstract: The study was carried out on the territory of the Botanical Garden of the Ural Branch of the Russian Academy of Sciences. The collection revealed 61 species from 37 genera and 20 families of woody plants that have become naturalized and have gone beyond the expositions. The highest rate of naturalization was observed in the Rosaceae, Sapindaceae and Oleaceae families. The capacity for naturalization was demonstrated by plants with Asian (19 species), Eurasian (17 species), North American (14 species) and European (5 species) distribution range. In terms of life-forms, among the naturalized species, may be divided as follows: trees – 34 species, 55.7 %, shrubs – 24 species, 39.3 %, lianas – 3 species, 5 %. Most of the naturalized species (85 %) are characterized by a very low occurrence on the territory of the arboretum and forest area in Botanical garden. Only 9 species of woody plants have maximum occurrence rates: Acer negundo, A. platanoides, Berberis vulgaris, Corylus avellana, Cotoneaster lucidus, Juglans mandshurica, Malus baccata, Quercus robur, Ribes rubrum.

Abstract: Abstract With data samples collected with the BESIII detector at seven energy points at s $$ \sqrt{s} $$ = 3.68 − 3.71 GeV, corresponding to an integrated luminosity of 333 pb −1, we present a study of the Λ transverse polarization in the e + e − → Λ Λ ¯ $$ \Lambda \overline{\Lambda} $$ reaction. The significance of polarization by combining the seven energy points is found to be 2.6σ including the systematic uncertainty, which implies a non-zero phase between the transition amplitudes of the Λ Λ ¯ $$ \Lambda \overline{\Lambda} $$ helicity states. The modulus ratio and the relative phase of EM-psionic form factors combined with all energy points are measured to be R Ψ = 0.71 − 0.10 + 0.10 $$ {0.71}_{-0.10}^{+0.10} $$ ± 0.03 and ∆ΦΨ = 23 − 8.0 + 8.8 $$ {23}_{-8.0}^{+8.8} $$ ± 1.6°, where the first uncertainties are statistical and the second systematic.

33. Інформаційно-правова характеристика основних складових сектору безпеки держави

Author: N. Yu. Cibulnyk
Subjects: безпека держави, національна безпека, сектор безпеки, інформаційна безпека, інформаційна характеристика, Law
Abstract: Стаття присвячена дослідженню інформаційно-правової характеристики основних складових сектору національної безпеки держави. Зазначено, що категорія «національна безпека» відображає якісний стан впорядкування суспільних відносин в державі та акцентує увагу на тому, що безпека держави полягає у забезпеченні національної ідентифікації. Встановлено, що забезпечення безпеки держави структуровано через диференціацію національної безпеки за секторально-видовою (включає: воєнну безпеку, громадську безпеку, державну безпеку, кібербезпеку, зовнішньо-політичну безпеку, екологічну безпеку, інформаційну безпеку) та суб’єктною ознаками (включає діяльність уповноважених суб’єктів). Поняття «сектор безпеки держави» визначено як сукупність правовідносин, зміст яких складає діяльність уповноважених суб’єктів щодо забезпечення національної безпеки в цілому, та за визначеними диференційованими напрямами. Запропоновано внесення змін до Закону України «Про національну безпеку». Акцентовано увагу на тому, що інформаційно-правова характеристика сектору безпеки держави є невід’ємною складовою національної безпеки держави в цілому та окремих її складових. Значущістю ліквідації інформаційних загроз інституціоналізовано окремий напрям безпеки держави – інформаційну безпеку. Встановлено, що кібербезпека є самостійною, похідною від інформаційної безпеки складовою безпеки держави, яка виокремилась в результаті розвитку цифрових технологій та поширення використання інформаційно-телекомунікаційних систем для цілей поширення інформації. Виокремлено інституційну систему забезпечення інформаційної безпеки, яка сформована з сукупності уповноважених суб’єктів, яких згрупувано залежно від їх правового положення та наявних повноважень в сфері інформаційної безпеки таким чином: 1) державні органи, що уповноважені забезпечувати національну безпеку; 2) органи виконавчої влади, які наділені повноваженнями в означеній сфері суспільних відносин; 3) правоохоронні органи; 4) допоміжні суб’єкти, які можуть здійснювати окрему діяльність, спрямовану на забезпечення інформаційної безпеки.

34. Ефективність механізму цілепокладання норм адміністративного права: поняття, сутність та значення

Author: N. Yu. Kantor
Subjects: норми адміністративного права, мета, механізм цілепокладання норм адміністративного права, ефективність, ефект, Law
Abstract: На підставі аналізу різноманітних підходів визначено теоретико-правові ідеї щодо ефективності механізму цілепокладання норм адміністративного права, а також висловлено авторську точку зору з деяких принципових аспектів порушеної проблематики. Зауважено, що авторка є прихильницею так званого комплексного підходу, згідно з яким оцінка будь якого явища з точки зору його ефективності має різноаспектне спрямовування. Разом з тим, слід відзначити, що враховуючи специфіку та зміст механізму цілепокладання норм адміністративного права, в основі такого оцінювання є пріоритетним саме цільовий підхід, згідно з яким здійснюється аналіз досягнення механізмом цілепокладання норми адміністративного права реальних кінцевих результатів, що уособлюються в правових наслідках реалізації норм. При цьому серед аспектів такого аналізу є блок соціальних та економічних оцінок, де першочерговість того чи іншого аспекту у тому чи іншому випадку визначається залежно від характеру, рівня або ж спрямування тої чи іншої групи норм адміністративного права яка піддається оцінці – тобто є безпосереднім предметом оцінювання на ефективність. Підкреслено, що соціальними чи економічними аспектами ефективність механізму цілепокладання норм адміністративного права не обмежується. Вказаний механізм може піддаватися оцінці на предмет політичного (визначає ефективність механізму цілепокладання в аспекті здатності держави виконувати внутрішні та зовнішні функції тощо); психологічного (оцінює здатність механізму цілепокладання забезпечувати сприйняття норм адміністративного права їх адресатами); конфліктного (визначає здатність механізму цілепокладання впливати на рівень конфліктності в суспільстві в цілому, у певній соціальній групі, колективі тощо) та інших аспектів. Констатовано, що ефективність механізму цілепокладання норм адміністративного права – це комплексна категорія, що включає у себе сукупність критеріїв та показників, що визначають рівень досягнення процесом формулювання та корегування цілей норм адміністративного права конкретних соціальних, економічних, політичних або інших результатів, що проявляється внаслідок реалізації вказаних норм.

Subjects: piglets, feed, nitrates, nitrites, antioxidants, enzymes, metisevit, Veterinary medicine, SF600-1100
Abstract: The work aimed to investigate the effect of the “Metisevit” feed additive on the activity of the enzymes of the antioxidant system of the blood of piglets under conditions of nitrate-nitrite load. The research was carried out on 60-day-old piglets of the large white breed. For the experiment, 10 clinically healthy piglets were selected, from which 2 groups of five animals were formed. Piglets of the control group were fed sodium nitrate at a dose of 0.3 g NO3-/kg body weight for three months. Piglets of the research group were also fed sodium nitrate at a dose of 0.3 g NO3-/kg of body weight, together with Metisevit at a dose of 0.36 g/kg of feed for three months. The “Metisevit” feed additive was developed at the Department of Pharmacology and Toxicology of the Stepan Gzhytskyi National University of Veterinary Medicine and Biotechnology Lviv, which contains vitamin E, selenium, and methiphene (methionine, phenarone, zeolite). Under the conditions of feeding piglets with sodium nitrate feed at a dose of 0.3 g of NO3ˉ/kg, a decrease in the activity of enzymes of the antioxidant defense system was established: superoxide dismutase by 14.8 %, catalase by 20%, glutathione peroxidase by 15.1 %. Metisevit in piglets increased the activity of the enzyme link of the antioxidant protection system, preventing the development of oxidative stress that occurs in nitrate-nitrite toxicosis. During our experiments, it was found that the introduction of Metisevit into the diet of piglets with excessive consumption of nitrates prevented the development of chronic nitrate-nitrite toxicosis. It was established that Metisevit increases the activity of enzymes – superoxide dismutase, catalase, and glutathione peroxidase. These enzymes reduce the high level of lipid peroxidation products in the body of piglets under conditions of nitrate-nitrite load.

Author: L. N. Eliseeva, N. Yu. Tikhomirova, O. I. Zhdamarova, and S. V. Ershova
Subjects: vitamin d, vitamin d deficiency, treatment of vitamin d deficiency, Medicine (General), R5-920
Abstract: Objective: to study the prevalence of vitamin D level disorders in therapeutic patients and the features of their correction. Materials and methods: 322 patients who applied for medical help in the field of therapy («rheumatology» and «cardiology») were examined. Materilas and methods: clinical, laboratory (study of the level of vitamin D in the blood), statistical. Results: it was found, that among patients with a therapeutic profile, vitamin D concentration disorders (deficiency and insufficiency) occur in 72.7% of the surveyed. There is a high prevalence of risk factors for osteoporosis in the examined patients: female sex prevails (81%), age (average age was 53.6 ±14.3 years), drug use (50% take proton pump inhibitors, 21.4% take glucocorticoids). When comparing the proportion of people with impaired vitamin D levels in comparison with the data of previous years, there was a decrease in the proportion of people with vitamin D deficiency and an increase in the proportion of people with vitamin D deficiency. Among people with a vitamin D level of 30-100 ng/ml, daily use of vitamin D preparations in dosages exceeding the recommended consumption levels was noted. Conclusion: based on the data obtained, the prevalence of vitamin D deficiency and insufficiency remains high. However, recently there has been a trend towards a decrease in the proportion of people with vitamin D deficiency and an increase in the proportion of people with vitamin D deficiency. In this connection, it is necessary to inform the population about the recommended adequate levels of vitamin D in blood serum and safe dosages of vitamin D preparations for daily intake.

Abstract: Abstract Based on 4.5 fb −1 data taken at seven center-of-mass energies ranging from 4.600 to 4.699 GeV with the BESIII detector at the BEPCII collider, we measure the branching fractions of Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ + hadrons relative to Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ π + π − . Combining with the world average branching fraction of Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ π + π − , their branching fractions are measured to be (0.377 ± 0.042 ± 0.020 ± 0.021)% for Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ K + K − , (0.200 ± 0.023 ± 0.011 ± 0.011)% for Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ K + π − , (0.414 ± 0.080 ± 0.030 ± 0.023)% for Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ ϕ and (0.197 ± 0.036 ± 0.009 ± 0.011)% for Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ K + K − (non-ϕ). In all the above results, the first uncertainties are statistical, the second are systematic and the third are from external input of the branching fraction of Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ π + π − . Since no signal for Λ c + $$ {\Lambda}_c^{+} $$ → Σ+ K + π − π 0 is observed, the upper limit of its branching fraction is determined to be 0.13% at the 90% confidence level.

Abstract: Abstract Utilizing 7.33 fb −1 of e + e − collision data taken at the center-of-mass energies of 4.128, 4.157, 4.178, 4.189, 4.199, 4.209, 4.219, and 4.226 GeV with the BESIII detector, the branching fraction of the leptonic decay D s + $$ {D}_s^{+} $$ → τ + ν τ via τ + → μ + ν μ ν ¯ $$ \overline{\nu} $$ τ is measured to be B D s + → τ + ν τ $$ {\mathcal{B}}_{D_s^{+}\to {\tau}^{+}{\nu}_{\tau }} $$ = (5.37 ± 0.17stat ± 0.15syst)%. Combining this branching fraction with the world averages of the measurements of the masses of τ + and D s + $$ {D}_s^{+} $$ as well as the lifetime of D s + $$ {D}_s^{+} $$ , we extract the product of the decay constant of D s + $$ {D}_s^{+} $$ and the c → s Cabibbo-Kobayashi-Maskawa matrix element to be f D s + $$ {f}_{D_s^{+}} $$ |V cs | = (246.7 ± 3.9stat ± 3.6syst) MeV. Taking |V cs | from a global fit in the standard model we obtain f D s + $$ {f}_{D_s^{+}} $$ = (253.4 ± 4.0stat ± 3.7syst) MeV. Conversely, taking f D s + $$ {f}_{D_s^{+}} $$ from lattice quantum chromodynamics calculations, we obtain |V cs | = 0.987 ± 0.016stat ± 0.014syst.

Abstract: Abstract Using 15.6 fb −1 of e + e − collision data collected at twenty-four center-of-mass energies from 4.0 to 4.6 GeV with the BESIII detector, the helicity amplitudes of the process e + e − → π + π − ω are analyzed for the first time. Born cross section measurements of two-body intermediate resonance states with statistical significance greater than 5σ are presented, such as f 0(500), f 0(980), f 2(1270), f 0(1370), b 1(1235) ± , and ρ(1450) ± . In addition, evidence of a resonance state in e + e − → π + π − ω production is found. The mass of this state obtained by line shape fitting is about 4.2 GeV/c 2, which is consistent with the production of ψ(4160) or Y(4220).

Abstract: Description of the features of morphology, internal structure, and analysis results of Th/U and Zr/Hf ratios in zircons from sandstones of the gold-bearing Alkesvozhskaya sequence, located at the basement of the Paleozoic section in the Subpolar Urals, is presented. It has been established that most of the studied zircons are primary igneous grains of the first weathering cycle. The detrital zircon source was probably in formations close in age, underlying or located nearby felsic and basic volcanics of igneous complexes of different stages of formation of Timanides-protouralides, associated granitoids, and intrusive mafic formations. Small part of well-rounded zircon Pre-Riphean grains can be redeposited from the Riphean metasedimentary formations, which, in turn, inherited it from the rocks of the ancient basement of the East European Platform

Subjects: fgf21, obesity, sex differences, liver, adipose tissue, hypothalamus, food intake, gene expression, Genetics, QH426-470
Abstract: In animals, obesity caused by consumption of a sweet-fat diet (SFD) is the most adequate mouse model of human diet-induced obesity. Fibroblast growth factor 21 (FGF21) reduces body weight, beneficially affects taste preferences, and corrects glucose metabolism in obese mice. Sex is known to influence FGF21 effects in different models of diet-induced and hereditary obesity. In mice with SFD-induced obesity, the effects of FGF21 have been studied only in males. The aim of this study was to compare the effects of FGF21 on body weight, food preferences and glucose and lipid metabolism in C57Bl/6J male and female mice with SFD-induced obesity. Mice were fed with a diet consisting of standard chow, lard and cookies for 10 weeks, then they were injected with FGF21 (1 mg per 1 kg) or vehicle for 7 days. Body weight, weights of different types of food, blood parameters, glucose tolerance, gene and protein expression in the liver, gene expression in the white, brown adipose tissues, and the hypothalamus were assessed. FGF21 administration reduced body weight, did not alter total energy consumption, and activated orexigenic pathways of hypothalamus in mice of both sexes. However, sex dimorphism was found in the realization of the orexigenic FGF21 action at the transcriptional level in the hypothalamus. Metabolic effects of FGF21 were also sex-specific. Only in males, FGF21 exerted beneficial antidiabetic action: it reduced fatty acid and leptin plasma levels, improved glucose-tolerance, and upregulated hepatic expression of Ppargc1, Fasn, Accα, involved in lipid turnover, gene Insr and protein glucokinase, involved in insulin action. Only in obese females, FGF21 induced preference of standard diet to sweet food. Thus, in mouse model of obesity induced by consumption of a sweet-fat diet, the catabolic effect of FGF21 was not sex-specific and hormonal, transcriptional and behavioral effects of FGF21 were sex-specific. These data suggest elaboration of different approaches to use FGF21 analogs for correction of metabolic consequences of obesity in different sexes.

Subjects: student youth, sociological survey, university communication, educational process, university infrastructure, university environment, students’ attitude towards teachers, Education
Abstract: The university environment includes various material and intangible aspects that are subjected now to active changes associated with both the development of information tech-nology and the new needs of young people. Therefore, the attitude of students to their university environment is an actual research topic. The Russian University of Transport (RUT (MIIT)) conducted the online survey of students, during which they were asked an open question regarding university problems and university development. The results showed that the problems associated with communication and mutual understanding, taking into account their opinions and interests, are of the greatest importance for modern students. The wishes of the students to the teaching staff were expressed, from which it is required both the ability to clearly explain the subject, and the presence of an individual and respectful approach to each student. We should not forget about the need of modern students in obtaining practice-oriented modern knowledge and skills, often associated with the need to rejuvenate teaching staff. Attention is paid to aspects related to improving the infrastructure of the university, the educational process. The problems related to the extracurricular scientific and educational life of the university, cultural and sports activities, environmental issues, schedule and mode of classes, work of educational departments are disclosed. The development of political education and patriotism in the university depends on small but effective events and the presence of an organizing groups. The novelty of the obtained data is due to the fact that the answers to an open question always differ from the opinions received in the course of polls with pre-proposed answers, and make it possible to identify hidden trends in public opinion. Respondents, in this case, express what worries them first of all, express the wishes that come to mind first, without prompts. The findings indicate the need to develop a strategy for improving the educational environment of the university, aimed at developing the possibilities of direct communication, increasing informal, understanding interactions.

Subjects: suppliers of raw materials and supplies, integral indicator of competitiveness, fuzzy logic methods, Transportation engineering, TA1001-1280
Abstract: Purpose. The current state of Ukraine's economy dictates the requirements for optimizing the selection of a reliable supplier to ensure the stable operation of the enterprise. Therefore, the authors believe that one of the main conditions for the company's activity is the improvement of logistics links. The main purpose of the study is to optimize the selection of suppliers of raw materials and supplies based on a logistics approach. Methodology. The article analyzes the performance indicators of suppliers of raw materials in the meat processing industry of Ukraine. The methodology for building an integral indicator of supplier competitiveness is presented. The modeling of the integral indicator of assessing the competitiveness of a raw material supplier using a fuzzy logic approach is carried out. The study was carried out using the methods of analysis and synthesis to determine the criteria and parameters for selecting a supplier of raw materials in order to organize the movement of material flows of the enterprise. Findings. The study found that the search for a new supplier of raw materials and supplies requires strict adherence to the selection algorithm. One of the elements of the algorithm is a study of the supplier market, which should be carried out using competitiveness indicators. The article assesses the competitiveness of pork and chicken suppliers in the Ukrainian market. The list of optimal suppliers for the uninterrupted supply of raw materials to meat processing enterprises is determined. Originality. The paper proposes a methodological approach to a more detailed analysis of raw material suppliers to enterprises, which allows applying elements of fuzzy logic to optimize the supplier selection process, unify diverse performance indicators, and compare the competitiveness of suppliers both within Ukraine and abroad. Practical value. The article proposes a model procedure for assessing the level of competitiveness of optimal suppliers of raw materials and supplies. The basis is the model of an integral indicator of competitiveness, the components of which are aggregate indicators. The use of fuzzy logic methods made it possible to formalize the obtained diverse indicators of activity of suppliers of raw materials and systematize them on a single scale. This made the supplier assessment model universal and expanded the possibilities of its use for practical purposes.

Subjects: caprine arthritis-encephalitis, lentivirus, pneumonia, pathomorphological features, small ruminants, Veterinary medicine, SF600-1100
Abstract: Over the past ten years, the small ruminant population in the Russian Federation grew sharply, especially goat population in backyards and on small-scale farms. Alongside with the population growth, clinical signs of some sporadic diseases or diseases that had not been previously registered were detected in animals. Caprine arthritis-encephalitis (CAE) is one of such diseases. It is a chronic infectious disease caused by a small ruminant lentivirus (SRLV) of the Retroviridae family, which includes four genotypes, of which genotypes A (maedi-visna – MVV virus) and B (caprine arthritis-encephalitis virus – CAEV) are of epizootic significance. The disease is characterized by long asymptomatic viral transmission and is associated with progressive lesions in the respiratory organs, joints and udder. The disease also affects nervous system in kid goats aged between 2 and 3 months. Clinical signs of caprine arthritis-encephalitis are not pathognomonic; therefore, it is often misdiagnosed, thus, resulting in a barrier to effective treatment. Given the fact, the issue of antemortem and postmortem diagnosis of caprine arthritis-encephalitis is still urgent, because most veterinary specialists have never encountered this disease and the data available in the literature often do not fully cover all clinical details and pathomorphological features. Therefore, the purpose of the work is to study CAE clinical signs and pathomorphological changes. The article describes in detail clinical manifestation of this disease, postmortem lesions in organs and tissues of the sick animals. The results obtained suggest that the destructive changes in the exposed organs are irreversible and, consequently, there is no effective treatment.

Subjects: secondary and tertiary hyperparathyroidism, shpt and thpt, quality of life, spf-36, subtotal parathyroidectomy, integrated patient management, Medicine
Abstract: Introduction. The problem of secondary hyperparathyroidism (SHPT) and tertiary hyperparathyroidism (THPT) has drawn the attention of numerous researchers in many countries, including those where kidney transplantation is a routine procedure. The most acute aspects include determining the most effective methods of therapeutic treatment, diagnostic and prognostic criteria, indications for surgery, its scope, and methods of avoiding relapses. The aim. To study the quality of life of patients who underwent surgery for secondary and tertiary hyperparathyroidism on the background of chronic kidney disease. Materials and Methods. During the study, we conducted a survey of 60 patients with secondary and tertiary hyperparathyroidism who underwent surgery between 2020 and 2023. The surveys were conducted twice: before the surgical intervention and within a period of up to 9 months after it. Among those surveyed, there were 35 (58%) women and 25 (42%) men. The average age of the respondents was 51.31±9.16 years. Results and Discussion. Quality of life is one of the most important indicators of the effectiveness of treatment. We observed an improvement in the quality of life in all surveyed patients with Tertiary Hyperparathyroidism (THPT) after surgical treatment. From the physical component point of view, this effect is undoubtedly associated with a decrease in the level of PTH and ionized calcium in the blood. This is evidenced by the significant correlation between these indicators and the obtained values of physical functioning scales before and after the operation. Conclusions. A significant correlation was observed between the levels of parathyroid hormone, ionized calcium, and physical functioning scales before and after surgery.

Abstract: 17β-Hydroxysteroid dehydrogenase 3 deficiency (17HSD3) is a rare autosomal recessive cause of 46, XY disorders of sex development resulting from HSD17B3 gene mutations, in which conversion of androstenedione to testosterone is impared. The clinical signs of 17HSD3 deficiency depend on the residual activity of the enzyme. The diagnosis of 17HSD3 deficiency is based on reduced testosterone/androstenedione ratio (T/AD < 0.8). Patients are usually assigned at birth and raise as female. If the diagnosis is made before puberty, gonadectomy is recommended, taking into account the risk of masculinization during the puberty and estrogen therapy initiation in this period. If the diagnosis of 17HSD3 deficiency is established during puberty, when virilization manifests, the therapeutic strategy is based on the results of comprehensive psychological testing and gender identity of a patient. In patients with more pronounced masculinization or diagnosis established shortly after birth, who are assigned at birth and raise as male, testosterone therapy is used to achieve a male phenotype. The 17HSD3 deficiency and virilization often result in a change of gender identity during puberty. The article presents a clinical case of 17-βhydroxysteroid dehydrogenase type 3 deficiency with late diagnosis due to parental will. The diagnostic approaches and management of the disease are also described.

Abstract: Abstract Using (447.9 ± 2.3) million ψ(3686) events collected with the BESIII detector, the decays of χ cJ → ϕϕ (J = 0, 1, 2) have been studied via the decay ψ(3686) → γχ cJ . The branching fractions of the decays χ cJ → ϕϕ (J = 0, 1, 2) are determined to be (8.59 ± 0.27 ± 0.20) × 10 −4, (4.26 ± 0.13 ± 0.15) × 10 −4, and (12.67 ± 0.28 ± 0.33) × 10 −4, respectively, which are the most precise measurements to date. From a helicity amplitude analysis of the process ψ(3686) → γχ cJ , χ cJ → ϕϕ, ϕ → K + K − , the polarization parameters of the χ cJ → ϕϕ decays are determined for the first time.

Subjects: diabetes mellitus, menopausе, osteoporosis, bone remodeling, sodium-glucose transporter 2 inhibitors, glucagon-like peptide-1 receptor agonists, Nutritional diseases. Deficiency diseases, RC620-627
Abstract: BACKGROUND: Diabetes mellitus (DM) is an independent risk factor for low-traumatic fractures. On the other hand, hypoglycemic drugs can have both positive and negative effects on bone remodeling.THE AIM: Тo investigate bone metabolism parameters during surgical menopause and experimental DM under the treatment with glucagon-like peptide receptor agonist type 1 (arGLP-1) liraglutide (LIRA) and sodium-glucose cotransporter type 2 inhibitor (iSGLT-2) canagliflozin (CANA).MATERIALS AND METHODS: Female Wistar rats have been subjected to bilateral ovariectomy at the beginning of the experiment. Diabetes mellitus (DM) was modelled using a high-fat diet and streptozotocin+nicotinamide. Four weeks after the following groups were formed: “OE+DM” (females after ovariectomy with DM and without any therapy, n=4) «OE+DM+CANA» (females after ovariectomy with DM under treatment with CANA, n=4), «OE+DM+LIRA» (females after ovariectomy with DM under treatment LIRA, n=5). The treatment or observation period were continuing for 8 weeks. Calcium, phosphorus and bone turnover markers (fibroblast growth factor-23 (FGF-23), osteocalcin, sclerostin, osteoprotegerin (OPG), nuclear factor-kappa-B receptor activator ligand (RANKL), were measured in the end of experiment. Bone histomorphometry was performed after euthanasia.RESULTS: Treatment with both CANA and LIRA did not significantly affect the phosphorus-calcium metabolism, sclerostin and osteocalcin concentrations. At the same time, the level of OPG was the highest in «OE+DM ‘’ group (9.1 [7.81; 10.045] pmol/l). The differences were significant compared with «OE+DM+CANA’’ (2, 33 [1.84; 5.84] pmol/l, p = 0.003) and «OE+DM+LIRA» (1.7 [1; 2] pmol/l, p = 0.003) groups. There were no differences in OPG levels between animals treated with different drugs. Similarly, the OPG/RANKL ratio was similarly reduced with both types of treatment. In “OE+DM+CANA’’ group the bone trabeculae number of the femur epiphysis (p=0.042) were decreased in comparison to «OE+DM» group. LIRA did not change the histoarchitectonic parameters.CONCLUSION: Bone metabolism markers did not differ when using as canagliflozin as liraglutide. Besides, canagliflosin can lead to the activation of bone resorption, which is expressed in the femur epiphyseal trabeculae number decreasing.
