Orienting Role of Terminology in Context of Its Scientific-Popular Conceptualization

The article examines the structural and functional properties of terms in popular scientific discourse. The authors aim to characterize the orientation of a term as a combination of its linguistic and functional properties, which define the concept expressed by the term, its connections with other concepts, and its place within the terminological system. The object of the study is linguistic and speech units in popular scientific texts, while the subject is the means of expressing orienting properties of terms in popular scientific discourse. The novelty of the research lies in studying the orienting properties of terms in popular scientific style based on their linguistic and speech properties, and providing a classification of these properties according to the scope and content of the expressed concepts. The relevance of the study is determined by the important role of these properties in the process of forming specialized concepts, understanding scientific, popular scientific, and educational discourses, and solving practical problems related to terminology use. The authors focus on the orienting function of a term, which is carried out through linguistic and speech means, with logical definitions, textual explanations, intercategorical connections expressed by elements of word formation and morpho-syntactic systems being the most active ones. The authors conclude that orienting properties of terms play a significant role in terminological conceptualization (formation of specialized concepts)

Coherent spin relaxation in molecular magnets

Numerical modelling of coherent spin relaxation in nanomagnets, formed by magnetic molecules of high spins, is accomplished. Such a coherent spin dynamics can be realized in the presence of a resonant electric circuit coupled to the magnet. Computer simulations for a system of a large number of interacting spins is an efficient tool for studying the microscopic properties of such systems. Coherent spin relaxation is an ultrafast process, with the relaxation time that can be an order shorter than the transverse spin dephasing time. The influence of different system parameters on the relaxation process is analysed. The role of the sample geometry on the spin relaxation is investigated.Comment: Latex file, 22 pages, 7 figure

Quality of life of patients with different forms of hemophilia on the example of Nizhny Novgorod region

It is important for public health to monitor and improve the health indicators of the population using the system of patient's quality of life (HRQoL) assessment regardless of the nosology of the disease. The use of HRQoL assessment provides health authorities with a tool for additional analysis of the performance of health services and for making decisions about funding priorities. The definition of HRQoL is one of the decisive factors in the calculation of QALYs because it measures the effectiveness of medical treatment in terms of how much it prolongs and/or improves patients' lives. The aim of the study is to determine the QALYs of hemophilia patients in Nizhny Novgorod region by means of electronic questionnaire using the SF-36 questionnaire. Methods. A validated SF-36 short form questionnaire was used in the study, which was distributed to adult patients with hemophilia A, B and Willebrand's disease of Nizhny Novgorod region together with a short form of informed voluntary consent. Twenty-eight people participated in the questionnaire. Calculation of general and final indicators of the HRQoL was carried out according to the instructions for processing data obtained with the SF-36 questionnaire. Results. The lowest score among all respondents was for GH "General Health Status" with a mean value of 61.00, and the highest score was for PF "Physical Functioning" with a mean value of 81.43. The study revealed that the majority of the surveyed patients were receiving Emicizumab (42.86 %). After comparing the ranges of values of the final indicators of physical (PH) and mental (MN') health in patients with different forms of hemophilia, the highest values of HRQoL indicators are observed in patients with hemophilia B, and the highest range of extreme values — in patients with hemophilia A. Conclusion. Patients with different forms of hemophilia are determined to have satisfactory values of HRQoL indicators, as all the results obtained in the course of the questionnaire are above the average value of the indicators. Mean HRQoL scores in patients receiving emicizumab are at a similar level compared to patients receiving other LPs, and fluctuations in HRQoL scores in these patients are less marked than in the other patients with hemophilia A

Economic analysis of the use of drugs for the treatment of hemophilia A, B and Willebrand's disease

Relevance. Therapy of hemophilia A, B and Willebrand's disease is carried out under the program of 14 VZN due to the use of federal budget funds. The use of funding is increasing in line with the growth of the total number of patients. In 2022,85.99 billion rubles were allocated, which corresponds to a 1.5‑fold increase in funding compared to 2018. The aim of the study was to conduct an economic analysis of the use of drugs for the therapy of hemophilia A, B and Willebrand's disease. Methods. The materials for the analysis were the dosing regimen of LPs selected on the basis of clinical recommendations, the availability of LPs in the 14 VZN program, and the prices for LPs from the State Register of maximum selling prices for VED drugs.

Фармакоэпидемиологический анализ и анализ межлекарственных взаимодействий в терапии хронической почечной и печеночной недостаточности

Objective: to perform pharmacoepidemiological and drug interaction analysis of pharmacotherapy for liver/kidney transplantation.Material and methods. The study was conducted on the basis of multidisciplinary hospital in Nizhny Novgorod, which provides both therapeutic and high-tech surgical care. The object of the study was medical records of 34 patients who had undergone pharmacotherapy for liver/kidney transplantation. We evaluated the particularly dangerous moderate interactions that pose the greatest risk to patient health using Drugs.com electronic resource. Pharmacoepidemiologic assessment was performed using the ATC/DDD methodology (anatomical therapeutic chemical (ATC) classification system – defined daily dose (DDD)) recommended by the World Health Organization. The “average bed occupancy per year” was calculated using DDD per 100 bed-days. ABC analysis was used to estimate the costs of drug groups in therapy for liver/kidney transplantation. Results. In most cases, the third generation cephalosporins were used in the therapy of liver/kidney transplant patients (55.56% of all prescriptions). Antimicrobial drugs were mostly prescribed as monotherapy (61.9%). There were 111 potential major (14.41%) and moderate (72.07%) interactions detected. The largest number of moderate type risks was associated with changes in blood pressure levels (in 23.75% of cases – possible decrease, in 10% – increase), 7.5% of cases were accompanied by headaches, 6.25% – by reduction of drug effectiveness. In antimicrobial therapy, two main interactions were found: moxifloxacin – tacrolimus (arrhythmia), and metipred – moxifloxacin (tendon dystrophy), which is 12.5% of all main interactions for 21 case histories. In the ABC analysis, immunosuppressants were in group A (cost share 85.8%). Tacrolimus accounted for the largest amount of consumption: number of defined daily doses (NDDD) per year was 532.27 mg, NDDD per 100 bed days reached 432.18 (the highest among all drugs).Conclusion. Pharmacoepidemiologic analysis allows us to systematize data on medication use. The choice of drugs in order to ensure safe and effective use of the registered drug interactions is facilitated by electronic databases.Цель: проведение фармакоэпидемиологического анализа и анализа межлекарственных взаимодействий при фармакотерапии, сопровождающей трансплантацию печени/почек.Материал и методы. Исследование выполнено на базе многопрофильного стационара г. Нижнего Новгорода, оказывающего как терапевтическую, так и высокотехнологичную хирургическую помощь. Объект исследования – медицинские карты 34 пациентов, проходивших фармакотерапию при трансплантации печени/почек. Оценивали особо опасные умеренные взаимодействия лекарственных препаратов (ЛП), представляющие наибольший риск для здоровья пациента, с помощью электронного ресурса Drugs.com. Фармакоэпидемиологический анализ проводили с использованием рекомендуемой Всемирной организацией здравоохранения методологии ATC/DDD (англ. anatomical therapeutic chemical (ATC) classification system – анатомо-терапевтическо-химическая классификация, defined daily dose (DDD) – установленная суточная доза) по показателю DDD за 100 койко-дней, рассчитывали показатель «средняя занятость койки в году». С помощью ABC-анализа оценили затраты на группы ЛП в терапии при трансплантации почек или печени.Результаты. В большинстве случаев в терапии больных при трансплантации печени/почек применялись цефалоспорины третьего поколения (55,56% среди всех назначений). Антимикробные препараты использовали преимущественно в качестве монотерапии (61,9%). Всего обнаружено 111 потенциальных взаимодействий, среди которых основные (major) составили 14,41%, умеренные (moderate) – 72,07%. Наибольшее количество рисков умеренного типа связано с изменением уровня давления (в 23,75% назначений возможно снижение, в 10% – повышение), 7,5% случаев сопровождаются головными болями, 6,25% – снижением эффективности ЛП. При антимикробной терапии обнаружено два основных взаимодействия: моксифлоксацин – такролимус (аритмия) и метипред – моксифлоксацин (дистрофия сухожилий), что составляет 12,5% от всех основных взаимодействий по 21 истории болезни. При проведении АВС-анализа в группу А входят иммунодепрессанты (доля затрат 85,8%). Наибольшее количество потребления приходилось на такролимус: число установленных суточных доз (англ. number of defined daily doses, NDDD) в год составило 532,27 мг, а NDDD за 100 койко-дней – 432,18 мг, что является самым высоким показателем среди всех ЛП.Заключение. Фармакоэпидемиологический анализ позволяет систематизировать данные об использовании ЛП. Выбор ЛП с целью обеспечения безопасного и эффективного применения зарегистрированных межлекарственных взаимодействий упрощается при использовании электронных баз данных

Mechanism of Disruption of the Amt-GlnK Complex by PII-Mediated Sensing of 2-Oxoglutarate

GlnK proteins regulate the active uptake of ammonium by Amt transport proteins by inserting their regulatory T-loops into the transport channels of the Amt trimer and physically blocking substrate passage. They sense the cellular nitrogen status through 2-oxoglutarate, and the energy level of the cell by binding both ATP and ADP with different affinities. The hyperthermophilic euryarchaeon Archaeoglobus fulgidus possesses three Amt proteins, each encoded in an operon with a GlnK ortholog. One of these proteins, GlnK2 was recently found to be incapable of binding 2-OG, and in order to understand the implications of this finding we conducted a detailed structural and functional analysis of a second GlnK protein from A. fulgidus, GlnK3. Contrary to Af-GlnK2 this protein was able to bind both ATP/2-OG and ADP to yield inactive and functional states, respectively. Due to the thermostable nature of the protein we could observe the exact positioning of the notoriously flexible T-loops and explain the binding behavior of GlnK proteins to their interaction partner, the Amt proteins. A thermodynamic analysis of these binding events using microcalorimetry evaluated by microstate modeling revealed significant differences in binding cooperativity compared to other characterized PII proteins, underlining the diversity and adaptability of this class of regulatory signaling proteins

Genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture

The study of genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture method from hybrids involved in the Latvian wheat breeding programme was performed. Flow cytometry was used to test ploidy of 3×103 cells of each green plantregenerant, and universal retrotransposon based iPBS (inter primer binding sites) method were used to establish genetic diversity of plants-regenerants. Progenies of 13 genetically distant hybrids were involved in the study. Most of plants-regenerants have leaves with mixoploid cells. Seeds were formed only by plants-regenerants that had cells with (2n = 6x) ploidy. Majority of fertile plantsregenerants have more than 40 % of hexaploid (6x) cells. The percentage of 6x cells in plants-regenerants and diversity in cell ploidy demonstrated association with mother plant (hybrid) genotype. Percent of spontaneous diplodization was also genotype-dependent. In this experiment colchicine treatment had no significant influence on outcome of fertile plants- regenerants. New dominant allele in a hybrid plant was found in comparison with both parents what indicated possible retrotransposon moving. Genetic diversity of the plants-regenerants obtained in anther culture is a combination of parent’s allele segregation and somaclonal variation
