Purpose. To analyze the main hemodynamic parameters in the central retinal artery, as well as their relationship with hemodynamic indicators in the central retinal vein, depending on the stage and type of active ROP with the use of color duplex scanning. Material and methods. The 63 premature babies with various stages of active ROP and no signs of ROP were included in the study. The 55 children with active ROP included in the study were distributed according to the stages and type of disease course. All children were at the same gestational age at the time of examination – 37–38 weeks of postmenstrual age or at 6–11 weeks of life. For all these children were performed color duplex scanning of the vessels of the eye and orbit in the modes of color Doppler mapping and pulsed Doppler. Results. The study of the hemodynamic features of the central retinal artery in premature infants with active ROP showed that the progression of the disease was accompanied by a significant increase in blood flow velocity (Vsyst and Vdiast) with each subsequent stage of ROP. A higher index of peripheral vascular resistance is recorded in comparison with the non-progressive favorable type for children with an unfavorable course of the disease.The analysis of the ratio of the maximum blood flow velocities in the central retinal artery and central retinal vein made it possible to determine in which of the vessels the hemodynamic changes are most pronounced, depending on the stage and form of active ROP. Conclusion. Thus, there are statistically significant changes in such large vessels of the retinal bed as the central retinal artery and central retinal vein during active ROP. Color duplex scanning, having a significant diagnostic potential in assessing hemodynamic parameters, made it possible to obtain reliable information about the linear blood flow velocity and the state of peripheral resistance in the central retinal artery and their relationship with the central retinal vein. This information opens up prospects for improving the accuracy of predicting the nature of the course of the disease, especially i n the early stages. Keywords: color duplex scanning, active retinopathy of prematurity, hemodynamic parameters, central retinal artery, central retinal vein

Published: December 2021

Purpose. To study the dynamics of interhemispheric interactions in children with friendly strabismus as a result of functional treatment. Material and methods. The study included 135 children aged 6 to 8 (average 6.8±0.1) years with convergent non-paralytic operated strabismus in combination with hypermetropic refraction and 96 children of the same age in the control group (average 7.1±0.1 years) without ophthalmic pathology. In children with strabismus, the leading hand and dominant eye were determined before and after functional treatment. Characteristics of spatial perception were evaluated by copying of complex geometric shapes which were Taylor's (right-handed) and Ray-Osterritz's (lefthanded). Results. After functional treatment in the group of children with non-paralytic strabismus, along with improved binocular functions and improved performance of the Taylor and Ray-Osterritz tests, there was an increase in the number of ambidextrous children and a significant decrease in the number of left-handers (p<0.001). Conclusion. The increase in the number of symmetrical lateral phenotypes against the background of improved binocular functions and spatial perception characteristics as a result of functional treatment of children with non-paralytic strabismus indicates an improvement of their interhemispheric interactions and can be an additional criterion for the ef fectiveness of treatment. Key words: lateral phenotypes, interhemispheric asymmetry, functional treatment of strabismus

Surgical treatment of rhegmatogenous retinal detachment with an inferior break remains a challenge for ophthalmic surgeons. When using silicone tamponade, complications can develop, such as increased intraocular pressure and emulsification of silicone. In recent years, tamponade of the vitreous cavity with a gas-air mixture has been actively used, however, not all patients can observe the forced position face down, and the tamponade itself is not long-term. Purpose. The authors proposed a method for the treatment of rhegmatogenous retinal detachment with an inferior break using a combined tamponade with a gas-air mixture and viscoelastic based on sodium hyaluronate. Material and methods. A clinical observation of a patient successfully operated on with the use of the specified combined tamponade is presented. A detailed description of a new surgical technique is presented, which allows achieving a higher anatomical and functional results. Conclusion. To confirm the effectiveness and safety of the proposed method, further studies on a group of patients are needed. Key words: rhegmatogenous retinal detachment, inferior break, gas-air tamponade, tamponade with viscoelastic, sodium hyalur onate

Аннотация. Освоение фольклора в бурятской прозе становится все более насыщенным,
писатели усваивают не только прямые, но и опосредованные формы фольклорного
материала, что делает такое взаимодействие более глубоким и многоплановым. Современная национальная литература в опосредованной или прямой форме содержит фольклорные
проявления, указывающие на специфические особенности национального характера в творчестве бурятских русскоязычных писателей. Актуальным представляется выявление такого
фольклорного опыта для определения закономерностей развития подобных литературно-фольклорных отношений и степени их взаимововлеченности. В изучении проблемы взаимосвязи литературы и фольклора главной целью в исследовании является выявление фольклорных мотивов в прозаических произведениях бурятской литературы. Научная новизна работы заключается в определении универсальных фольклорных проявлений, указывающих на специфические особенности национального характера в творчестве бурятских русскоязычных писателей.
В качестве методов исследования применены сравнительно-типологический анализ и герменевтический метод. По результатам работы выявлен комплекс фольклорных истоков
и мотивов в произведениях современной бурятской литературной прозы, представляющих собой универсальные подходы для выражения национального характера, были определены роли, функциональные возможности и особенности фольклорных единиц. Литературоведческие поиски решения проблемы взаимосвязи литературы и фольклора, а также проявления национального
характера вызывают пристальный интерес исследователей-фольклористов. Перспективы
дальнейшего исследования проблемы мы видим в более детальном изучении проявления фольклорного опыта в современных произведениях бурятских писателей, что способствует более детальному раскрытию национального характера народов Сибири, в том числе в аспекте сравнительно-сопоставительного анализа.
The structure and electronic properties of fluorinated graphene
Authors: ШАРИН Е.П.
Published: December 2021

Аннотация. Графен обладает целым рядом уникальных свойств, чем и привлекает внимание
многих исследователей. Кроме фундаментального интереса, связанного с «релятивистским» поведением носителей заряда, графен перспективен как материал для приборов нано-,
оптоэлектроники и плазмоники. Когда мы говорим о достоинствах приборов на основе графена, в литературе везде упоминаются: высокая подвижность электронов, возможность эффективного управления электрическими и оптическими свойствами с помощью внешнего напряжения. Эффективность в данном случае обусловлена низкой плотностью электронных состояний, которая определяется линейной зависимостью энергетического спектра от волнового вектора. Основным препятствием к применению графена в электронике является отсутствие запрещенной зоны между валентной зоной и зоной проводимости. Химическая модификация графеновых слоев имеет большое значение для разработки новых материалов, поскольку она не только открывает щель между валентной зоной и зоной проводимости, но и позволяет контролировать ее ширину. Поэтому одной из областей исследований таких систем является химическая функционализация, а именно адсорбирование атомами фтора графена. В данной работе мы изучили структурные и электронные свойства фторированного графена в зависимости от концентрации атомов фтора и от их местоположения в кристаллической решетке, используя вычисления из первых принципов, основанные на теории функционала плотности. Результаты показывают, что электронные
свойства фторированного графена сильно зависят от степени фторирования и местоположения атомов в кристаллической решетке.

Аннотация. Приводятся сведения о повышенном содержании микроэлементного состава в теле рыб после строительства Вилюйской ГЭС. На его содержание повлияло извлечение минерального сырья, особенно алмазодобывающей промышленности. Изучены изменения условий обитания гидробионтов рек Северо-Востока Якутии, включая бассейн Колымы, их питания, роста и размножения, проанализированы изменения размерно-возрастной и половой структуры в процессе усиливающегося антропогенного воздействия. Задачей данного исследования является оценка состояния организмов рек на основании морфо-патологического анализа, а также описание
основных морфологических аномалий в жизненно важных органах рыб (печень, почки, жабры,
гонады), изучение закономерности накопления тяжелых металлов и их распределения в организме рыб и разработке рекомендации по оптимизации управления рыбными ресурсами в бассейне
Колымы. Для всех рыб проводился полный общебиологический анализ (морфометрия, размерно-возрастной состав, оценка численности и т. п.), дана оценка аномалий методом патолого-
анатомического анализа, а для части рыб проводились специальные биохимические исследования
(анализ крови и определение концентрации тяжелых металлов в органах и тканях рыб). Обнаружены почечно-каменная болезнь (нефрокальцитоз) у исследованных рыб, патологии в скелете рыб – мопсовидное рыло, искривление жаберных тычинок и ребер, образование горба и слияние 2-3 позвонков в грудной клетке. При интоксикации организма обнаружены следующие аномалии печени и почек: отмирание клеток и появление на их месте соединительной ткани. Нарушение структуры и функционирования
популяций рыб, возникновение глубоких патологий и дисфункций в их организме привели к снижению рыбохозяйственного потенциала водоемов Якутии, в том числе и бассейна Колымы.

Published: December 2021

Alkenes are ubiquitous, and radical difunctionalization of alkenes represents one of the most practical approaches to constructing value-added compounds. Dicarbonylation of alkenes provides direct access to value-added 1,4-dicarbonyl compounds. However, selectivity control for unsymmetric 1,2-dicarbonylation is an unclosed challenge. We herein describe NHCs and photocatalysis co-catalyzed three competent radical 1,2-dicarbonylation of alkenes by distinguishing two carbonyl groups, providing structurally diversified 1,4-diketones. Mechanistic studies indicated that NHCs-stabilized ketyl-type radicals originate from aroyl fluorides via oxidative quenching process of excited photocatalysis, and acyl radicals are generated from single-electron-oxidation of α-keto acids. Distinct properties of acyl radical and NHCs-stabilized ketyl radical contributed to selectivity control. Transient acyl radicals are rapidly added to alkenes delivering alkyl radicals, which undergo subsequent radical-radical cross-coupling with ketyl-type radicals, affording 1,2-dicarbonylation products. This transformation features mild reaction conditions, broad substruct scope, and excellent selectivity, providing a general and practical approach for the dicarbonylation of olefins.

The COVID-19 pandemic has highlighted the need of eco-friendly and locally or distributed manufacturing of diagnostic and safety products. Here, we characterized five handmade papers for their potential application to make paper analytical device (PADs). The handmade papers were made from locally available plant fiber using eco-friendly method. Thickness, grammage, and apparent density of the paper samples ranged from 198 μm to 314 μm, 49 g/m2 to 117.8 g/m2, and 0.23 to 0.39 g/cm3, respectively. Moisture content, water filtration and wicking speed ranged from 5.2% to 7.1%, 35.7 to 156.7, and 0.062 to 0.124 mms-1, respectively. Further, water contact angle and porosity ranged from 76˚ to 112˚ and 79% to 83%, respectively. The best paper sample one was chosen to fabricate PADs which were used for the determination of metformin. The metformin assay on PADs followed linear range from 0.0625 to 0.5 mg/mL. The assay had limit of detection and limit of quantitation of 0.05 mg/mL and 0.18 mg/mL respectively. The new method was used to test metformin samples (n=20) collected from local pharmacies. The average amount of metformin concentration in samples was 465.6 ± 15.1mg/tablet. Three samples did not meet the regulatory standards. When compared with spectrophotometric method, PADs assay correctly predicted 18 out of 20 samples. The PADs assay on handmade paper may provide a low-cost and easy-to-use system to screening the quality of drugs and other point-of-need applications.

Molecular motions are ubiquitous in nature and they immutably play intrinsic roles in all actions. However, exploring appropriate models to decipher molecular motions is an extremely important but very challenging task for researchers. Considering aggregation-induced emission (AIE) luminogens possess their unique merits to visualize molecular motions, it is particularly fascinating to construct new AIE systems as model to study molecular motion. Herein, a novel quinolizine (QLZ) AIE system was constructed based on the restriction intramolecular vibration mechanism. It was demonstrated that QLZ could act as an ideal model to visualize single-molecule motion and macroscopic molecular motion via fluorescence change. Additionally, further elaborate tailoring of this impressive core achieved highly efficient reactive oxygen species production and realized fluorescence imaging-guided photodynamic therapy applications, which confirms the great application potential of this new AIE-active QLZ core. Therefore, this work not only provides an ideal model to visualize molecular motion but also opens a new way for the application of AIEgens.

(–)-Anisomelic acid (AA), isolated from Anisomeles indica (L.) Kuntze (Labiatae) leaves, is a macrocyclic cembranolide with a trans-fused α-methylene-β-lactone motif. Cytopathic effect assays showed that the anti-SARS-CoV-2 effect of AA (IC50 = 4.3 μM) is comparable to that of remdesivir (IC50 = 2.1 μM), and more potent than that of molnupiravir (IC50 = 27.8 μM). Challenge studies in SARS-CoV-2-infected K18-hACE2 mice showed that oral administration of AA and remdesivir can both reduce the viral titers in the lung tissue at the same level. To facilitate drug discovery, we used a semisynthetic approach to shorten the project timelines. The enantioselective semisynthesis of AA from the naturally enriched and commercially available starting material (+)-costunolide was achieved in five steps with a 27% overall yield. The developed chemistry provides opportunities for developing AA-based novel ligands for selectively targeting proteins involved in viral infection.
Organophotoredox/Ni-Cocatalyzed Allylation of Allenes: Regio-, and Diastereoselective Access to Homoallylic Alcohols
Authors: Xie Hui , Breit Bernhard
Published: December 2021

A dual organophotoredox/nickel-catalyzed reductive coupling of allenes with aldehydes has been developed for the rapid assembly of anti-homoallylic alcohols with high levels of regioselectivities (>20:1), and diastereoselectivities (up to >20:1) and yields (up to 91%). The allylation was realized through a crucial π-allylnickel intermediate which was obtained via insertion of allenes with a Ni−H intermediate. Moreover, γ,γ-disubstituted homoallylic alcohols with a quaternary stereocenter can also be prepared by this protocol.
Discovery of Innovative Polymers for Next-Generation Gas-Separation Membranes using Interpretable Machine Learning
Authors: Yang Jason , Tao Lei , He Jinlong , McCutcheon Jeffrey , Li Ying
Published: December 2021

Polymer membranes perform innumerable separations with far-reaching environmental implications. Despite decades of research on membrane technologies, design of new membrane materials remains a largely Edisonian process. To address this shortcoming, we demonstrate a generalizable, accurate machine-learning (ML) implementation for the discovery of innovative polymers with ideal separation performance. Specifically, multitask ML models are trained on available experimental data to link polymer chemistry to gas permeabilities of He, H2, O2, N2, CO2, and CH4. We interpret the ML models and extract chemical heuristics for membrane design, through Shapley Additive exPlanations (SHAP) analysis. We then screen over nine million hypothetical polymers through our models and identify thousands of candidates that lie well above current performance upper bounds. Notably, we discover hundreds of never-before-seen ultrapermeable polymer membranes with O2 and CO2 permeability greater than 104 and 105 Barrer, respectively, orders of magnitude higher than currently available polymeric membranes. These hypothetical polymers are capable of overcoming undesirable trade-off relationship between permeability and selectivity, thus significantly expanding the currently limited library of polymer membranes for highly efficient gas separations. High-fidelity molecular dynamics simulations confirm the ML-predicted gas permeabilities of the promising candidates, which suggests that many can be translated to reality.
Dynamics of methyl radical formation by 266 nm photolysis of xylenes and mesitylene
Authors: Bejoy Namitha Brijit , Kawade Monali , Singh Sumitra , Patwari G Naresh
Published: December 2021

The 266 nm photodissociation of three xylene isomers and mesitylene leading to the formation of methyl radical was examined. The kinetic energy release profiles for the methyl radical were almost identical for all the three isomers of xylene and mesitylene, while substantial differences were observed for the corresponding profiles of the co-fragment produced by loss of one methyl group. This observation be attributed to the formation of the methyl radical from alternate channels. The total kinetic energy distribution profiles were rationalized based on the dissociation of {sp2}C–C{sp3} bond in the cationic state, wherein the {sp2}C–C{sp3} bond dissociation energy is lowered relative to the ground state. The dissocaiton in the cationic state follows a resonant three-photon absorption process, resulting in maximum total kinetic energy of about 1.6 – 1.8 eV for the photofragments. A results in. Fitting of the TKER distribution profiles to empirical function reveals that the dynamics of {sp2}C–C{sp3} bond dissociation is insensitive to the position of substitution but marginally dependent on the number of methyl groups.

THE POTENTIAL OF EDUCATIONAL MIGRATION FROM CHINA, VIETNAM AND JAPAN IN THE CONTEXT OF SOLVING THE DEMOGRAPHIC AND SOCIO-ECONOMIC PROBLEMS OF RUSSIA
Authors:   Institute for Demographic Research FCTAS RAS, Khramova Marina N. , Shipilova Maria A. ,   MGIMO University

In the modern world, educational migration is gaining in scale, and the list of countries attractive to foreign youth is also expanding. Leading universities, included in various rankings, implement many educational programs aimed at attracting foreign students. For Russia, increasing the number of foreign students in universities is one of the priority tasks set in the National Education Project. In this work, based on data from the Ministry of Science and Higher Education of the Russian Federation, as well as data from Rosstat, we analyze the dynamics of the number of foreign students from a number of Asian countries in Russian universities. It is shown that over the past ten years, the number of foreign students studying in Russia for undergraduate and graduate programs has doubled. This became possible both thanks to the active work of universities in positioning Russian educational programs, and thanks to a number of interstate agreements that allow foreign students to receive education in Russia for free. And, although the main potential for attracting foreign students is still concentrated in the CIS countries, Russia has good chances of increasing flows of educational migrants from the countries of the Asia-Pacific region, including China, Japan and Vietnam. We are formulating a number of proposals that can help increase the attractiveness of Russia for students from these countries.

Published: December 2021

Children’s perspective is based on their own cognitive level in understanding objective things. The study of children’s perspective is a bottom-up research process under the premise of having a full respect for a child’s view.

At the same time, teacher-child interaction, as an important means of evaluating the quality of kindergarten education, requires a bottom-up perspective from children. This study hopes to understand children’s emotional experience in the process of teacher-child interaction as well as their understanding and evaluation of their own experience by exploring their perspectives on the interaction, so as to better improve the quality of teacher-child interaction in kindergarten.

The Aesthetic Education Value of Thematic Art Creation
Authors: Cui Yingying
Published: December 2021

Thematic art creation is a product of a complex social, historical, and cultural context, and it fills an important position in the development of modern and contemporary Chinese art history. Since the 21st century, with the introduction and implementation of a series of national major thematic art creation projects, thematic art creation has gradually moved from a marginal position in art history to a core area, becoming a visual narrative method with independent aesthetic value. Moving towards cultural consciousness and carrying cultural self-confidence, thematic art creation requires the guidance, standardization, and support of related art theories. The lack and absence of theoretical research restricts the development of thematic art creation. This study combs through the research results and literature materials of thematic art creation since the new century as well as studies the aesthetic education value of thematic art creation image narration.
