The synthesis and antiproliferative evaluation of novel D-glucopyranuronamide-containing nucleosides is described. Based on our previously reported anticancer D-glucuronamide-based nucleosides, new analogues comprising N/O-dodecyl or N-propargyl substituents at the glucuronamide unit and anomerically N-linked 2-acetamido-6-chloropurine, 6-chloropurine or 4-(6-chloropurinyl)methyl triazole motifs were synthesized in 4-6 steps starting from acetonide-protected glucofuranurono-6,3-lactone. The methodologies were based on the access to N-substituted glycopyranuronamide precursors, namely 1,2-O-acetyl derivatives or glucuronoamidyl azides for further N-glycosidation with a nucleobase or 1,3-dipolar cycloaddition with N9 and N7-propargyl-6-chloropurines, respectively. N-Propargyl glucuronamide-based N9-linked purine nucleosides were converted into (triazolyl)methyl amide-6,6-linked pseudodisaccharide nucleosides via cycloaddition with methyl 6-azido glucopyranoside. A CuI/Amberlyst A-21 catalytic system employed in the cycloaddition reactions also effected conversion into 6-dimethylamino purine nucleosides. Antiproliferative evaluation in chronic myeloid leukemia (K562) and breast cancer (MCF-7) cells revealed significant effects exhibited by the synthesized monododecylated purine-containing nucleosides. A N-propargyl 3-O-dodecyl glucuronamide derivative comprising a N9-β-linked 6-chloropurine moiety was the most active compound against MCF-7 cells (GI50 = 11.9 μM) while a related α-(purinyl)methyltriazole nucleoside comprising a N7-linked 6-chloropurine moiety exhibited the highest activity against K562 cells was (GI50 = 8.0 μM). Flow cytometry analysis and immunoblotting analysis of apoptosis-related proteins in K562 cells treated with the N-propargyl 3-O-dodecyl glucuronamide-based N9-linked 6-chloropurine nucleoside indicated that it acts via apoptosis induction.

The catalytic oxidation of HCl by molecular oxygen (Deacon process) over ceria allows the recovery of molecular chlorine from omnipresent HCl waste produced in various industrial processes. Previous density functional theory (DFT) model-calculations1 proposed, that the most critical reaction step in this process is the displacement of tightly bound chlorine at a vacant oxygen position on the CeO₂(111) surface Cl(vac) towards a less strongly bound cerium on-top Cl(top) position. This step is highly endothermic by more than 2 eV. On the basis of a dedicated model study, namely the re-oxidation of a chlorinated single crystalline Cl(vac)-CeO₂₋ₓ(111)-(√3 × √3)R30° surface structure, we provide unique spectroscopic data (high resolution core level spectroscopy (HRCLS) and X-ray adsorption near edge structure (XANES)) for this oxygen-induced de-chlorination process. Combined with theoretical evidence from DFT calculations, the Cl(vac) → Cl(top) displacement reaction is predicted to be induced by a surface-adsorbed peroxo species (O₂²⁻), making the displacement step concerted and exothermic by 0.6 eV with an activation barrier of only 1.04 eV. The peroxo species is shown to be important for the re-oxidation of Clvac-CeO₂₋ₓ(111) and is considered essential for understanding the function of ceria in oxidation catalysis.
Electrical surface properties of nanoporous alumina membranes: influence of nanochannels curvature, roughness and composition studied by electrokinetic experiments

Published: June 2023

Among classical nanoporous oxide membranes, anodic aluminum oxide (AAO) membranes, made of non-connected, parallel and ordered nanochannels, are very interesting nanoporous model systems widely used for multiple applications. Since most of these applications involve local phenomena at the nanochannel surface, the fine description of the electrical surface behavior in aqueous solution is thus of primordial interest. Here, we use an original experimental approach combining several electrokinetic techniques (tangential and transverse streaming potential as well as electrophoretic mobility experiments) to measure the ζ-potential and determine the surface isoelectric points (IEPs) of several AAOs having different characteristic sizes and compositions. Using such an approach, all the different surfaces available in AAOs can be probed: outer surfaces (top and bottom planes), pore wall surfaces (i.e., inner surfaces) and surfaces created by the grinding of the AAOs. We find clear IEP differences between the outer, pore wall and grinded surfaces and discuss it in terms of nanochannel and surface morphology (curvature and roughness) and of modifications of the chemical environment of the surface hydroxyl groups. These results highlight the heterogeneities between the different surfaces of these AAO membranes and emphasize the necessity to combine complementary electrokinetic techniques to properly understand the material, approach which can be extended to many nanoporous systems.
Beyond Poor Cows and Angry Young Women: Extraordinary Female Voices in the Narratives of Nell Dunn and Shelagh Delaney
Authors:   , Lowe Rosemary
Published: June 2023

Post-war British writers Nell Dunn and Shelagh Delaney have long been associated with the gritty Kitchen Sink school of social realism. Defined as female versions of Angry Young Men, their working-class female characters have been categorised as poor cows. This characterisation has been emphasised by film versions of their work, for which they wrote the screenplays. Delaney’s play A Taste of Honey (1958) was made into a film in 1961, seen as the embodiment of Northern Kitchen Sink social realism. Dunn’s Up the Junction (1963) and Poor Cow (1967) were both made into films by Ken Loach. Over time, Dunn’s voice has been lost amid the wider Loach canon and this has resulted in a reductive reading of her prose. This thesis explores the narratives of both authors outside this trend and emphasises the hope and humour also present in these texts, a hope that overrides desolation. I read Dunn beyond her seminal works Up the Junction and Poor Cow and include her sequel to Poor Cow, My Silver Shoes (1996). These two narratives have not previously been explored together. I discuss conversation as a literary device and the collective collaborative female voice in Dunn’s Talking to Women (1965). This thesis explores the authors’ voices through their own insights into their work and the collective female voices found through their lived experience in working-class communities. These communities embodied youth, vitality and joy, female camaraderie, and the importance of having a good laugh. This thesis focuses on Dunn’s use of dichotomy and bathos as literary devices, creating humour and hope within desolation. It offers a reimagining of their works beyond that of poor cows and angry young women and a restoration of the extraordinary female voices in their narratives.

Published: June 2023

Osteometry of the foramen magnum was assessed for discriminant function analysis of biological sex estimation and population affinity estimation based on post-mortem computed tomography (PMCT) images in this Malaysian population-based study.
This retrospective cross-sectional study was performed using convenient sampling of PMCT skull images originating from 300 Malaysian adults. Linear dimensions of the foramen magnum transverse diameter (FMTD) and anterior-posterior diameter (FMAPD) were measured. Statistical analyses were performed via independent t-test, ANOVA, univariate and multivariate analyses concurrently with discriminant function analyses.
There were significant differences in FMTD and FMAPD between males and females within respective population affinities. The foramen magnum dimensions of males were comparably larger than females. There were relatively significant differences in FMTD and generally sufficient significant differences in FMAPD among population affinities. The osteometry of foramen magnum dimensions of Chinese were generally larger than Malays and Indians.
Discussion and Conclusion: Foramen magnum dimensions had a stronger discriminant function in biological sex estimation with 60% accuracy as compared to population affinity estimation with only 40.7% accuracy. FMTD and FMAPD are the potential sex discriminators among the Malaysian population particularly if other indicators are not available for evaluation.
The State-of-the-art Technique for Determining the Identity and Uniqueness of Common Color Laser Printouts by Coded Dot Matrix Patterns
Authors: S. Salim Ahmad , A. Abdalla Asmaa
Published: June 2023

Recently, in forensic science studies, identification of the source of color laser printouts is one of the most challenging issues that hinder forensic document examiners. Although various methods for establishing the identity of the source of color laser printouts are currently available worldwide, none of those methods approaches an accuracy and precision of 100%.
The coded dot matrix patterns are state-of-the-art prototypes of steganography based on the active technique. Upon tracking the coded dot matrix patterns of all investigated color laser printouts, the identity and uniqueness can be determined, respectively.
In the current paper, nineteen variant brands of color laser printer machines were selected. The advanced security features embedded in their printouts have steganalysis and grouped them into two broad categories. A direct model of hyperspectral analysis integrated with video spectral comparator Regula® 4307 was applied.
The complete identification of the investigated color laser printouts was achieved. The decisive degree of the results reached one hundred percent for the investigated color laser in this study. Moreover, the novel classification scheme of coded dot matrix patterns presents for completing the individual characteristics.

Nowadays, the measurement of respiratory dynamics is underrated at clinical setting and in the daily life of a subject, still representing a challenge from a technical and medical point of view. In this article we propose a concept to measure some of its parameters, such as the respiratory rate (RR), using four inertial sensors. Two different experiments were performed to validate the concept. We analyzed the most suitable placement of each sensor to assess those features and studied the reliability of the system to measure abnormal parameters of respiration (tachypnea, bradypnea and breath holding). Finally, we measured post-COVID-19 patients, some of them with breath alterations after more than a year of the diagnosis. Experimental results showed that the proposed system could be potentially used to measure the respiratory dynamics at clinical setting. Moreover, while RR can be easily calculated by any sensor, other parameters need to be measured with a sensor in a particular position.

Published: June 2023

Sharia Supervisory Board (DPS)  in sharia banking plays an important role in supervising the activities of sharia banking to make sure that the bank can be free from usury (interest), gharar (unclear contract), and maisir (speculation). DPS in Islamic banks is expected to make Islamic banks more obedient to the rules. This study examines the effect of the DPS characteristics on risk-taking and tax avoidance behavior in Indonesian Islamic banking from 2010-2019. The characteristics studied included DPS financial expertise and the number of DPS meetings. Financial expertise is measured by the number of DPS who have expertise in finance. The research method used is multiple linear regression. The test results show that the number of DPS who are financial experts does not affect risk-taking behavior at Islamic banks. In contrast, the number of DPS meetings positively affects Islamic bank risk-taking. Then the number of DPS who are financial experts has a positive effect on tax avoidance at Islamic banks while the number of DPS meetings has no effect on tax avoidance at Islamic banks. The results of this study can be used as determinant to issue policies related to DPS responsibilities to maximize its role as a supervisory board in tax avoidance and risk taking.

В статье исследуется эволюция национального проекта «Производительность труда» с момента его объявления в 2018 г. и до настоящего времени. Анализ открыто опубликованных результатов проекта позволил выявить проблемы, связанные с оценкой его эффективности. В частности, отмечены противоречия в данных, отсутствие верифицируемой информации о повышении производительности труда на предприятиях-участниках, а также анализа причин, по которым почти половина предприятий не достигла целевых показателей. Были обнаружены высокая межрегиональная дифференциация по количеству предприятий-участников, некоторые перекосы в финансировании. Кроме того, тот факт, что 77% участников проекта представляют всего 15 видов экономической деятельности, вызывает вопросы относительно активности предприятий других отраслей.
Гарантия спроса: паллиатив или выход из стагнационной ловушки?
Authors: Алексеев А.В.
Published: June 2023

В работе рассматривается проблема выхода из стагнационной ловушки, в которую попала российская экономика в результате некритической имплементации в практику управления основных положений неолиберальной теории, ничем неоправданного стремления вписаться в глобальные экономические связи на любых условиях, слабого запроса российского общества на осмысление роли государства в управлении экономикой и низкого качества этого управления. Обосновывается необходимость резкого усиления стратегического планирования, придания нового качества государственному управлению экономикой в части расширения ответственности за формирование гарантированного спроса на продукцию масштабных инвестиционных проектов отечественного бизнеса, адаптации института государственно-частного партнерства к изменившимся после февраля 2022 г. реалиям.

О Стратегии социально-экономического развития Сибири: риски, проблемы, решения
Authors: Тулохонов А.К.
Published: June 2023

Автор статьи подвергает критическому разбору новую редакцию Стратегии социально-экономического развития Сибири до 2035 г. Серьезные замечания вызывают некоторые формулировки; перечень приоритетных направлений развития (кластеров) представляется неполным – не отражающим имеющийся потенциал и не отвечающим интересам развития территории. При описании развития транспортной, энергетической инфраструктуры, некоторых ключевых отраслей специализации игнорируются не только современные технологические достижения, но и мировые тренды развития. Наконец, совершенно не учитываются реалии новой геоэкономической и геополитической ситуации, глобальные климатические изменения. Автор приходит к выводу, что новая Стратегия устарела уже в момент выхода и предлагает пересмотреть ее содержание, расширив охват документа до всей азиатской части России.

Published: June 2023

Postinfarction left ventricular (LV) aneurysm develops as a result of untimely restoration of blood flow in the infarct-dependent artery and is associated with an increase in cardiac mortality. The presence of several postinfarction LV aneurysms of different localizations in one patient is a rare and casuistic case.

Case description. Patient B., 53 years old, was urgently hospitalized in the National Amosov Institute with complaints of shortness of breath, pain behind the sternum with radiation to the left arm, occurring with minimal physical exertion. Electrocardiography showed scar changes in the anterior-apical-lateral area of the LV with a thrombosed aneurysm of the LV lateral wall. Echocardiography revealed a severe decrease in the global contractility of the LV with ejection fraction of 24% and aneurysms of the septal-apical and posterior-lateral segments of LV. Pericarditis was found, with a layer of fluid of 1.7 cm on the LV posterior wall and 2.0 cm on the LV apex. Emergency coronary angiography revealed an occlusion of the middle third of the left anterior descending artery and the middle third of the left circumflex coronary artery, 50-70% stenosis of the right coronary artery and confirmed widespread LV aneurysm. Cardiac magnetic resonance imaging with intravenous contrast confirmed the change in configuration and significant dilatation of the LV due to the formation of two LV aneurysms with mural thrombus in the cavity of the posterior-lateral LV aneurysm. After discussing the patient’s data, the cardiac team performed emergency on-pump coronary bypass surgery, resection of the LV aneurysm with thrombectomy. The operation took 5 hours, aorta cross-clamp time was 75 min, perfusion time was 117 min, intraoperative blood loss was 300 ml. The patient was extubated in 2 hours after the end of the operation, the length of intensive care unit stay was 2 days. On the 9th day after the operation, the patient was discharged from the Institute with positive clinical, electrocardiographic and echocardiographic (LV ejection fraction 38%) dynamics.

Conclusions. This clinical case demonstrates successful surgical treatment of two LV aneurysms, a rare complication of acute myocardial infarction. Preoperative detailed diagnosis and discussion of the patient’s data by the heart team, selection of the optimal term and volume of the operation allowed to quickly stabilize the patient’s condition and achieve a positive immediate result.
Surgical Emphysema without Pneumothorax: A Diagnostic Dilemma
Authors: Sathanantham Dinesh Kumar , Sanganbhonia Spurthi , Shashirekha C. A. , Sreeramulu P. N.
Published: June 2023

Surgical emphysema, also widely known as subcutaneous emphysema, is defined as a clinical state in which air gets trapped subcutaneously. The etiology may be traumatic or atraumatic, and multiple causes in each are present.

Case report. A 63-year-old female patient presented to the emergency room with a facial soft tissue injury following road traffic accident and developed surgical emphysema later on with no evidence of rib fractures or pneumothorax. Infectious etiology was ruled out. Due to the respiratory embarrassment, the patient was electively intubated. Conservative management was provided. Emphysema resolved within 24 hours after the accident.

Discussion. Various theories have been outlined in literature, like Mackler effect, Crampton theory and ballvalve mechanism. In our case, it was difficult to apply any of these theories to confirm the diagnosis. Conservative management is still used in the treatment of surgical emphysema.

Conclusion. Surgical emphysema is a common encounter in trauma practice, and its identification is essential to rule out any emergency causes which may lead to respiratory distress.
Extended Reality Applications in Cardiac Surgery and Interventional Cardiology
Authors: Petrov Vitaliy F. , Pankiv Mariana V.
Published: June 2023

Extended reality combines the real and digital worlds. This technology has found applications in all fields of medicine, including cardiac surgery and interventional cardiology. The paper describes the application of three types of extended reality, namely virtual, augmented and mixed realities.

The aim. To explain the principles of operation of various types of extended reality using non-medical and medical applications as examples; to analyze the data from specialized publications in the field of cardiac interventions.

Materials. Articles from the Pubmed database.

Results. The article highlights important details of the heart and blood vessels image creation technique with which users operate. Primary data is obtained from imaging modalities like tomography or ultrasound, then it is segmented and processed for the virtual viewing. In virtual reality, three-dimensional (3D) images of the heart defects are analyzed in depth, and virtual manipulations can be performed that simulate the course of the operation. Virtual reality includes printing the heart on a 3D printer with subsequent executions on physical models, both diagnostic dissections and therapeutic surgical or endovascular simulations. In augmented reality, the created image of the internal anatomy of the defect is present near the surgeon, without interfering medical manipulations. In mixed reality, a virtual image is superimposed on the patient’s body, creating a detailed navigation map.

Conclusions. Extended reality application deepens the understanding of anatomy due to stereoscopic visualization of the structure of the heart and blood vessels. Creating a model of a patient’s heart defect and simulating an operation on it shortens the “learning curve”, improves the professional skills of surgeons and cardiologists, and also allows for surgical and endovascular interventions individualization. Planning interventions in cardiac surgery and interventional cardiology with extended reality technologies influences decision-making and reduces the duration of operations.

The aim of the study was to determine the risk factors for the occurrence of acute heart failure (AHF) of high degrees (Killip classes III and IV) among patients with myocardial infarction (MI).

Materials and methods. We examined 308 MI patients who were treated at the specialized cardiology department. The mean age of the subjects was 62.9±0.6 years. There were 161 (52.3%) patients with MI without signs of heart failure (HF) (Killip class I), 44 (14.3%) with MI combined with class II AHF, 55 (17.8%) with MI and class III AHF, and 48 (15.6%) with MI and Killip class IV AHF. In addition to the general clinical examination, all the patients underwent additional laboratory examination (quantitative determination of troponin I, D-dimer, creatine kinase-MB, C-reactive protein, N-terminal prohormone of brain natriuretic peptide [NT-proBNP]), echocardiography and lung ultrasound during hospitalization, as well as coronary angiography.

Results. A correlation between the occurrence of class III AHF (pulmonary edema) and class IV AHF (cardiogenic shock) and a number of anamnestic, clinical, functional and laboratory indicators was established. The following predictors of the development of class III AHF among patients with MI were calculated through regression analysis: a decrease in the level of O2 saturation during hospitalization, an increase in blood pressure during hospitalization, localization of the main heart attack-related lesion of the distal part of the right coronary artery, a decrease in the left ventricular ejection fraction. With less significance, predictors of the development of class III AHF were also defined as a decrease in the level of hemoglobin, the duration of hypertension in the history, the degree of hypertension, the history of any form of atrial fibrillation.

Conclusions. A decrease in diastolic blood pressure irrespective of medical support and an increase in the level of NT-proBNP were established as predictors of the development of Killip class IV AHF. Further studies to predict the occurrence of HF and long-term consequences after MI with high-grade HF are promising and can provide an opportunity to optimize the treatment of patients by preventing severe complications.
