Morphometric criteria for healthy endometrium in mares
Authors: Лебедева Л.Ф. , Дубровская А.Б. , Устьянцева А.В.
Published: July 2024

Статья посвящена проблеме поиска критериев оценки репродуктивных качеств кобыл на основе морфометрических показателей гистосрезов эндометрия. Показано, что в норме у молодых здоровых кобыл (n=8) в фазе диэструса плотность эндометриальных желез в губчатом слое достоверно выше (16,9±1,1 ед.п.з.), чем в эструсе (10,0±0,7 ед.п.з.) (p<0,001). После 10 лет у кобыл (n=13) на гистологическом уровне наблюдается растяжение желез и уменьшение их количества (p<0,001), главным образом, в результате фиброзных изменений эндометриальной ткани и потери ее эластичности. Эти изменения непосредственно связаны с фертильностью кобыл. Поэтому предложен эндометриальный показатель - отношение диаметра желез (Дд) к их плотности (Пд) (в среднем по 10 полям зрения) в губчатом слое в диэструсе (ЭП=Дд/Пд) для оценки воспроизводительных качеств кобыл, который в норме не должен превышать 2-3 мкм/ед.п.з.

The article is devoted to the problem of finding criteria for assessing the reproductive qualities of mares on the basis of morphometric indicators in histological samples of the endometrium. It was shown that in young healthy mares (n =8) in the diestrus phase, the density of endometrial glands in the Stratum Spongiosum layer of endometrium is significantly higher (16.9 ± 1.1 units) than in oestrus (10,0 ± 0,7 units) (p <0.001). After 10 years (n=13) in mares, at the histological level, stretching of the glands and decrease in their number (p <0.001) is observed, mainly as a result of fibrotic changes in the endometrial tissue and loss of its elasticity. These changes are directly related to the fertility of the mares. Therefore, an endometrial indicator is proposed - the ratio of the diameter of the glands (Dd) to their density (average over 10 fields of view) in diestrus (EI = Dd / Nd) for assessing the reproductive qualities of mares, which normally should not exceed 2-3 microns / unit.

Published: July 2024

С целью определения целесообразности допуска кобыл к воспроизводству в первую охоту после выжеребки проведён анализ показателей зажеребляемости и эмбриональной смертности в зависимости от дня первой овуляции. Исследовано распределение послеродовых овуляций по дням и уровень повторяемости продолжительности периода до первой овуляции после смежных жерёбостей. В обработку вошли данные по 336 послеродовым овуляциям и 162 парам послеродовых овуляций, учтённых у 101 головы маток рысистых пород, содержащихся на двух конных заводах центральной России, в случных сезонах 2013-2016 и 2019-2022 годов. Установлено, что 59,8±2,7% первых овуляций происходит с 10 по 14 день после выжеребки (p≤0,001). Зажеребляемость при проверках на 12 день составила 28,6; 57,3; 79,7% (p≤0,001) при овуляциях, происходящих на 9 день с 10 по 13, с 14 по 21 день, соответственно. Наибольшее количество эмбриональных потерь (11,8 - 36,4%) наблюдается, если овуляция происходит до 16 дня после выжеребки. С учётом эмбриональных потерь достоверная разница (21,4%, p≤0,05) в зажеребляемости на 35 день найдена при овуляциях до и после 12 дня. В 61,7% (100/162, p <0,001) случаев у одной и той же кобылы послеродовые овуляции происходят с разницей 0-2 дня, в 16,1% (26/162) - с разницей в 3-4 дня. Полученные данные позволяют прогнозировать день овуляции у ранее жеребившихся кобыл с известным сроком послеродовой овуляции.

In order to determine the expediency of allowing mares to reproduce in the first heat after foaling, an analysis of the indicators of conception and embryonic mortality, depending on the day of the first ovulation, was carried out. The distribution of postpartum ovulations by days and the level of repeatability of the duration of the period before the first ovulation after adjacent foals were studied. The processing included data on 336 postpartum ovulations and 162 pairs of postpartum ovulations recorded in 101 Trotter mares kept at two studs in central Russia in the breeding seasons of 2013 - 2016 and 2019 - 2022. It was found that 59.8±2.7% of the first ovulations occur from 10 to 14 days after the foal (p≤0.001). The pregnancy rate during the tests on day 12 was 28.6; 57.3; 79.7% (p≤ 0.001) with ovulations occurring on day 9 from 10 to 13, from 14 to 21 days, respectively. The greatest number of embryonic losses (11.8 - 36.4%) is observed if ovulation occurs before the 16th day after foaling. Taking into account embryonic losses, a significant difference (21.4%, p<0.05) in conception on day 35 was found at ovulations before and after day 12. In 61.7% (100/162, p <0.001) of cases in the same mare, postpartum ovulation occurs with a difference of 0-2 days, in 16.1% (26/162) - with a difference of 3-4 days. The data obtained make it possible to predict the day of ovulation in previously foaled mares with a known period of postpartum ovulation.

Published: July 2024

Here, we report the first practical synthesis of the bulky phosphanide anion [P(SiiPr3)2]− in synthetically useful yields, and its complexation to Group 12 metals. The ligand is obtained as the sodium salt (DME)NaP(SiiPr3)2 1 (DME = 1,2-dimethoxyethane) in 36% isolated yield and a single step from red phosphorus and sodium. This far exceeds previous yields for this ligand (ca. 9.8% overall yield over 3 steps), and we have thus applied 1 to the synthesis of the two coordinate complexes M[P(SiiPr3)2]2 (M = Zn, Cd, Hg). These Group 12 complexes are all monomeric and with non-linear P–M–P angles [163.593(18)° to 170.086(16)°] in the solid state, with DFT calculations suggesting that this bending is due to the steric demands of the ligand. Multinuclear NMR spectroscopy revealed complex 2nd order splitting patterns due to strong PP’ coupling. This work demonstrates that the synthesis of 1 is viable and provides a springboard for the synthesis of low-coordinate d-block complexes featuring this unusual bulky ligand.

Controlling the dynamic behavior of highly reactive fleeting intermediates is an intriguing concept to generate selectivity in competing reaction pathways. Here we report the directed evolution of a P450 enzyme for anti-Markovnikov-selective Wacker-Tsuji-type oxidation of aliphatic alkenes. This reaction is a long-standing challenge in catalysis due to its unfavorable energetics and competing reactions. The evolved aMOx-A enzyme performs anti-Markovnikov oxidation of aliphatic alkenes with several hundred turnovers and possesses kinetic parameters comparable to those of average natural enzymes. The biocatalyst guides an oxo-transfer process through multiple competing reactions, including bifurcating reaction pathways that originate after a rate-limiting transition state. Chemoselectivity of aMOx-A arises from controlling substrate conformations as well as dynamics of reactive intermediates. This includes accessing and controlling a fleeting carbocation intermediate that does not correspond to a minimum on the potential energy surface. Engineering of aMOx-A highlights how directed enzyme evolution optimizes unique catalytic processes that have largely eluded efficient catalysis.

Published: July 2024

Extracellular vesicles (EVs) derived from corneal epithelial cells have shown great promise in promoting corneal wound healing and stromal regeneration but face challenges with rapid clearance from the eye. This study addresses this challenge by developing a sustained release platform using a biocompatible collagen-based hydrogel. We successfully isolated, purified, and characterized corneal epithelial EVs, assessed their efficacy in corneal epithelial healing in vitro, and demonstrated their sustained delivery over ten days followed by an on-demand release through enzymatic degradation of the hydrogel. To develop a microscale understanding of the EV-diffusion inside the hydrogel matrix, we probed the hydrogel network with several model compounds and nanoparticles by using advanced confocal microscopy analyses followed by fitting our results to established diffusion models. Our findings suggest this innovative approach offers a safe and effective strategy to promote corneal wound healing. This technology has the potential to revolutionize corneal injury treatment and improve patient outcomes.
Electric fields at solid-liquid interfaces: Insights from molecular dynamics simulation
Authors: Nauman Julia , Suvlu Dylan , Willard Adam
Published: July 2024

In this manuscript, we explore the electrostatic environment of the interface between a solid and a dilute electrolyte solution, with an emphasis on the electric field profiles that these systems produce. We review the theoretical formalism that connects electrostatic potential profiles, electric field profiles, and charge density fields. This formalism has served as the basis for our understanding of interfacial electric fields and their influences on microscopic chemical and physical processes. Comparing various traditional models of interfacial electrostatics to the results of molecular dynamics (MD) simulation yields mutually inconsistent descriptions of the interfacial electric field profile. We present MD simulation results demonstrating that the average electric field profiles experienced by particles at the interface differ from the properties of traditional models and from the fields derived from the mean charge density of atomistic simulations. Furthermore, these experienced electric field profiles are species-dependent. Based on these results, we assert that a single unifying electrostatic potential profile - the gradient of which defines a single unifying electric field profile - cannot correctly predict the electrostatic forces that act on species at the interface.

ASSESSMENT OF THE QUALIFICATIONS OF SCIENTISTS BASED ON PUBLICATIONS IN SCIENTIFIC JOURNALS OF THE SCOPUS AND WEB OF SCIENCE DATABASES IN REGULATORY DOCUMENTS OF KAZAKHSTAN
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Turginbayeva Ardak , Makanova Asselya
Published: July 2024

Kazakhstan’s accession to the Bologna process led to a transition to the Western model of personnel training as well as to the adoption in 2011 of new regulatory legal acts (RLA), which legislated the introduction of new methods for assessing the qualifications of scientists based on publications in journals indexed in the Scopus and Web of Science (WoS) international databases. Changes were systematically made to these RLAs, which were dictated both by the high dynamism of the development of the scientific field and the formation of new challenges and threats that required solutions. The article examines the dynamics of amendments to the RLA regarding the requirements for journals included in the Scopus and WoS international databases to publish research results by Kazakhstani authors. The method of content analysis of the contents of the texts of RLA and a bibliometric approach were used to assess the impact of changes in legal regulations on quantitative indicators of the publication activity of Kazakhstani authors in international journals. Based on the analysis, 4 conditional stages in the development of state science policy were identified. The first stage – 2011-2014 – the adoption of the Law “On Science” and the reorientation of researchers to publications in international journals. Second stage – 2015-2018 – relaxation of requirements for international journal publications, particularly for applicants for academic titles in the social and humanitarian fields. Third stage – 2019-2022 – harmonization of legal regulations regarding requirements for journals for the publication of research results and the introduction of alternative options for publication channels depending on the scientific direction of scientists, as well as the development of changes to the requirements in the RLA based on proposals from the Council of Young Scientists. The fourth stage – 2023-2024 – further expansion of alternative options for publishing research results in journals included in international databases. It was revealed that at the initial stage of introducing a method for assessing the qualifications of scientists based on publications in journals included in international databases, the potential of RLA had a significant effect on the number of publications of Kazakhstani authors in the Scopus and WoS databases. Then, this potential decreased and the introduction of new instruments of state science policy is required to stimulate the growth of publication activity of Kazakhstani authors.
THE PLACE AND ROLE OF DECISIONS OF THE CONSTITUTIONAL COURT OF THE REPUBLIC OF KAZAKHSTAN IN THE SYSTEM OF SOURCES OF CONSTITUTIONAL LAW
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Tusupova Almagul , Baimakhanova Dina
Published: July 2024

The article examines the significance and relevance of decisions made by the Constitutional Court of Kazakhstan within the context of the country's constitutional legal system. This topic's theoretical and practical significance is determined by the revival of the constitutional control institution in the Republic of Kazakhstan, which is an important factor in changing the country's legal system. This allows us to consider the role of constitutional justice decisions as a source of law and their legal force and scope. The decisions of the Constitutional Court of the Republic of Kazakhstan play a significant role in the legal regulation of public affairs. Certain categories of decisions by the Constitutional Court, such as those that address compliance with the Kazakhstani Constitution, laws, and other regulatory legal acts, as well as those issued in response to complaints from citizens or requests from courts regarding the constitutionality of specific laws, are considered part of the system of constitutional law in Kazakhstan. These decisions serve to clarify and interpret the provisions of the Kazakh Constitution. The issue of the role of decisions by the Constitutional Court as a source of constitutional law is an important one, as there are two opposing approaches to this issue. According to the first approach, the Constitutional Courts are law enforcement agencies that do not create new legal norms. However, according to the other approach, along with their law enforcement role, the Constitutional Courts also engage in law-making, and many of their decisions have a normative significance, making them a source of law, including constitutional law. The authors of the article discuss the special status of the Constitutional Court as an institution of constitutional review, the importance of the decisions it makes, their unique legal characteristics, as well as their position and role within the system of sources of constitutional law.

Published: July 2024

In the present study, the issues of teacher resilience and the persistent gender stereotypes in the field are discussed. The main objective of the conducted research study was to examine the presence of gender-stereotype-confirming behavior in coping with adversity in vocational school teachers. The Connor-Davidson Resilience Scale CDRISC-25SLOVAKwas selected as the most suitable research instrument, by means of which gender differences in the participants’ (N=474) responses in its subscales were studied. The results obtained confirmed the hypothesis presuming the existence of gender differences in the achieved scores in five of the seven dimensions of the scale, and also stereotype-confirming behaviors—according to which men are rational problem solvers while women tend to apply emotion-focused coping strategies—were reported. This knowledge can be the first step towards introducing measures with the aim to provide individuals of all genders with opportunities to broaden their scale of coping strategies and promote resilience in them. Since vocational school teachers are on the periphery of researchers’ interest and no available extensive study has been focused on gender differences in teacher resilience, the research findings aim to fill the gap in the existing knowledge, provide unique data for policymakers, and create a basis for further resilience research. Doi: 10.28991/ESJ-2024-SIED1-011 Full Text: PDF
