Authors: Alfianti Dewi , Muhammad Budi Zakia Sani
Published: August 2023

Meski sudah berumur ratusan tahun dan menjadi satu literatur penting mengenai asal usul dan budaya urang Banjar, Hikayat Banjar masih belum dikenal dan dipahami dengan baik oleh masyarakat Kalimantan Selatan. Dalam penelitian mengenai resepsi siswa SMA IT Ukhuwah mengenai Hikayat Banjar pada tahun 2021 yang disajikan dalam bentuk video pertunjukan wayang kreasi, dapat diketahui bahwa sebagai sampel masyarakat kota Banjarmasin, mereka tidak terlalu mengenal dan memahami Hikayat Banjar. Oleh karena itu Pengabdian kepada Masyarakat (PKM) ini dilakukan dalam rangka menciptakan satu sumber literatur yang lebih populer untuk kembali mengenalkan Hikayat Banjar yaitu buku cerita rakyat Hikayat Banjar dengan sasaran pembaca siswa sekolah dasar dan menengah. Kegiatan PKM ini akan dilaksanakan di Kampung Buku Banjarmasin Selatan pada bulan Juni-Agustus 2022. Para peserta yang berpartisipasi akan diberikan pelatihan mengenai penulisan cerita rakyat, lalu mereka akan membuat satu buku cerita rakyat berdasarkan Hikayat Banjar. Buku kemudian dicetak dan dibagikan ke sekolah dan komunitas literatur di kota Banjarmasin.

Budget deficits and public debt of Ukraine under the shocks of pandemic and military aggression
Authors:   NGO “Growford Institute”, BOHDAN Tetiana , BOHDAN Ivan ,   National Bank of Ukraine
Published: August 2023

Introduction. The extraordinary conditions for the government’s functioning during the pandemic and warfare provoked a strong respose of the state institutions, as a result of which the size of budget deficit in Ukraine over 2022-2023 exceeded a lot the historical values and averages for the different country groups as most indicators of the debt burden worsened, generating the danger of debt unsustainability. Problem Statement. Identification of the nature of Ukraine’s fiscal policy through the lens of past and contemporary global phenomenon, identification of macro-financial factors impacting he state of debt sustainability under the extreme conditions, analysis of debt burden indicators and fiscal risks in order to outline the ways of solving the fiscal and debt problems in Ukraine. Purpose. To reveal the global patterns and national features of the expansive fiscal policy conduct and public debt accumulation in emergency conditions which are connected with the pandemic and military actions , to investigate the factors of Ukrainian government’s solvency deterioration and to assess the relevant risks, as well as to define the tools of public debt management in the medium run. Methods. General scientific and special methods are applied: analysis and synthesis, description and comparison, historical method, method of theoretical generalization and abstract-logical method. Results. It has been found that the impact of operations of the general government on aggregate demand in Ukraine was positive in 2020, 2021 and 2022, and this situation was in sharp contrast to the period of 2015-2019, when fiscal policy produced restrictive effects. Fiscal policy in Ukraine was of pro-cyclical nature in 2014-2018 and turned to countercyclical stance only in 2020 with sustaining this course until 2023. It has been proven that in Ukraine the debt sustainability criteria are violated across major part of debt burden indicators , that signal the high solvency risks and liquidity risks for general government; moreover, relative to 2019, the dynamics of most indicators in 2020 and 2022-2023 were unfavorable. Computations conducted indicate that refinancing risks, foreign exchange and interest rate risks inherent to the structure of public debt have increased significantly with the start of hostilities in Ukraine. Conclusions. In the post-war period, contraction of budget deficit and well-balanced restructuring of the external public debt should become the main levers for debt reduction. Effective management of public debt with consideration of existing risks are important for securing macro-financial stability and active government’s involvement in the post-war reconstruction of the country.
The impact of some external factors on financial instability in Ukraine
Authors:   SІ “Institute for Economics and Forecasting of NAS of Ukraine”, BUBLYK Ievgen
Published: August 2023

Introduction. The nature of Ukraine's economic development over the past thirty years reflects its dependence on global financial and economic cycles. The nature of this dependence lies in the stable interrelationship of the global commodity markets with factors of internal financial stability. One of the important ways to overcome such dependence is a nationally-rooted monetary policy aimed at supporting domestic economic activity and weakening the influence of the external environment on financial stability. Problem Statement. Increasing the internal financial stability of the national economy and the regulatory potential of monetary policy by limiting their dependence on global economic cycles. Purpose: Formalization of the relationship between the financial stability of the national economy and changes in the global commodity markets and the identification of prospective monetary policy measures to mitigate them. Methods. General scientific and special methods are used : theoretical generalization, systematic, abstract-logical and comparative analysis, synthesis, grouping. Results. The article summarizes the regularities that determine the cyclical repetition of financial and economic crises in Ukraine. In particular, it was noted that the stability of small open economies, a significant share of whose income is formed by the export of raw materials, largely depends on the situation on the global raw materials markets. Cyclical downturns in these markets cause financial crises, which lead to the decapitalization of small open economies and thus make their structural innovative development impossible. Conclusions. In order to ensure the sustainable development of small open raw material economies, it is necessary to carry out an appropriate institutional policy of the state aimed at ensuring the development of a more complex economic base with a departure from raw material dependence. This requires a corresponding modernization of monetary policy in terms of expanding control over the movement of capital flows, limiting the volatility of the exchange rate.
Народні школи Херсонської губернії у ХІХ ст.
Authors: Мінц Микола
Published: August 2023

Розглядається процес зародження, створення та розвитку народних шкіл на території Херсонської губернії. У ХІХ ст. з’являються новий тип шкіл – земські, міністерські, грамоти, церковнопарафіяльні (підпорядковувалися Святійшому Синоду), які у сукупності отримали назву народні школи, де навчалися діти селян, містян, робітників. Але процес створення нових шкіл йшов повільно. Не вистачало будівель для організації навчального процесу, була відсутня матеріальна база, не вистачало фінансів на оплату праці вчителів.

У середині 1860-х років відбулася низка реформ, у тому числі й освітянська, що певною мірою сприяло подальшому розвитку народної освіти. Земства взяли на себе відповідальність за організацію початкової освіти на селі, підготовку вчителів, фінансування народних шкіл. Зросла потреба у вчительських кадрах. З цією метою органи місцевого самоврядування, церква, Міністерство освіти до роботи в школі почали залучати священнослужителів, різночинців, відставних військових, дворян.

З метою підвищення їх професійної майстерності проводилися вчительські курси, з’їзди та різного роду навчання вчителів, зароджувався інспекторський контроль, який позитивно вплинув на якість викладання навчальних предметів. У процесі навчання вчителі використовували передові на той час методики: ланкастерська, толстовська, німецька, пояснювальне читання.

У початкових школах на уроках використовувалися наочність, різного роду прилади, малюнки тощо. До кінця ХІХ ст. початкова школа стала основним навчальним закладом для народу та виконала своє завдання з поширенню писемності серед населення.

Проаналізовано основні наукові праці, що стосуються повсякденного життя шляхти Правобережної України від Січневого повстання 1863 р. до революції 1917 р., коли дворянство, як стан, перестало існувати.
Головні засади партійно-державної політики щодо протестантських організацій у радянській Україні у 1920-ті рр.
Authors: Сітарчук Роман , Фазан Василь
Published: August 2023

Характеризується політика радянсько-більшовицької влади щодо об’єднань адвентистів сьомого дня, баптистів, євангельських християн і християн євангельської віри (в тексті: протестанти / євангелісти) у радянській Україні у 1920-ті рр. – період особливо насичений подіями, оскільки відбувався процес інституалізації протестантських організацій.

У роботі простежено еволюцію радянського законодавства про культи, яке регулювало діяльність протестантських організацій, та тісно пов’язаної з ним політики більшовицької партії у релігійному питанні. Механізм поступової, з урахуванням кон’юнктури суспільства, ліквідації протестантських об’єднань був запущений на початку 1920-х рр. З того часу почали формуватися фундаментальні чинники більшовицько-радянської політики: невідповідність слів і діла, домінування демагогії та цинізму в судженнях про релігію тощо. Стала нормою практика розходження змісту широкомасштабних декларацій і таємних циркулярів, що визначали практичні дії офіційних органів, спецслужб, сприяли зростанню зловживань щодо протестантів на місцях. Законодавство, політика щодо євангелістів за своєю суттю були фактично антирелігійними і загалом негативно позначилися на ефективній життєдіяльності громад, гальмували їх розвиток.
П’ятидесятники Південної Бессарабії під тиском радянської репресивної машини (на прикладі справи Соломії Істоміної та Василя Попазогло)
Authors: Тригуб Олександр
Published: August 2023

Розкрито одну із окремих кластерних сторінок реалізації централізованої агентурної справу «Пророки» на теренах Ізмаїльської області (сьогодні – західна частина Одеської області) – кримінальну справу ізмаїльських п’ятидесятників Соломії Істоміної та Василя Попазогло. Показано хід слідства, сутність звинувачень і рішення суду, яке свідчить про збереження жорсткої політики щодо п’ятидесятників часів пізнього сталінізму.

Автор приходить висновку, що не дивлячись на проголошену у післявоєнний час видиму релігійну свободу, сталінська тоталітарна система залишилася вірною своїй традиційній репресивній політиці по відношенню до духовенства та віруючих усіх конфесій. Разом з тим, справа свідчить і про значне послаблення репресивної машини по відношенню до п’ятидесятників за часів «хрущовської відлиги», бо вже протягом 1955-56 рр. засуджені були звільнені. Натомість бачимо й іншу сторону цього процесу, що свідчить про двоїстість хрущовської політики реабілітації – засуджені не були повністю реабілітовані, а лише звільнені (при цьому Комісія визнала В. Попазогло «неправильно засудженим»).

Перспективами дослідницької праці у запропонованому напрямку вважаємо вивчення усього наявного корпусу кримінальних справ щодо протестантів пізньосталінської доби, визначення загальних і відмінних тенденцій, формування усієї картини агентурно-оперативної роботи щодо прихильників цих конфесій тощо.
Доля єпископа Союзу християн євангельської віри Панаса Бідаша у контексті об’єднавчого процесу (на матеріалах архівних справ НКВС-МДБ)
Authors: Бабенко Людмила
Published: August 2023

На матеріалах архівно-кримінальних справ радянських органів держбезпеки досліджено роль єпископа союзу Християн євангельської віри п’ятидесятників (ХЄВ) Панаса Бідаша у боротьбі за свободу віросповідання. Показано цілеспрямований вплив органів радянської влади та оперативних підрозділів Наркомату державної безпеки – Міністерства державної безпеки на очільників і віруючих громад християн євангельської віри з метою повного контролю за їх діяльністю та об’єднання з баптистами. У результаті агентурно-оперативних дій спецслужбам вдалося під час створення Всесоюзної ради євангельських християн-баптистів (ВРЄХБ) схилити до співпраці її керівництво.
Справа про співпрацю активу євангельських християн Миколаївщини з окупаційною владою Німеччини (1941-1944 рр.)
Authors: Федоренко Михайло , Макарчук Сергій
Published: August 2023

На основі дослідження справи № 1269-с, що зберігається в архіві УСБУ в Миколаївській області, надано аналіз документам Міністерства державної безпеки щодо слідства, яке відбулося в 1946 р. по відношенню до активу євангельських християн Миколаївщини. Встановлено, що звинувачення євангельського активу в тісній співпраці з органами окупаційної влади, має в основному штучний характер. Обвинувачення у видачі гестапо громадян нелояльних нацистському режиму не знайшло реальних доказів. Агітація віруючих на користь окупаційного режиму носила епізодичний характер і відбувалася під примусом. Зроблено висновок, що сам процес над євангельським активом є продовженням антирелігійної політики комуністичної партії та радянської влади періоду пізнього сталінізму 1944-1953 рр.
Позиція ЄС у Придністровському конфлікті
Authors: Герасименко Максим
Published: August 2023

Досліджено проблему Придністров’я та спроби ЄС в її вирішеннї; прослідковано динаміку зовнішньополітичних відносин Молдови та Придністров’я з ЄС; охарактеризовано ключові проблеми, які не дають змоги вирішити конфлікт від 1992 р. по нинішній час. У статті окремо розкрито соціально-економічні фактори всередині країни та інструменти, які використовував Європейський Союз. Враховано політичні позиції обох сторін конфлікту (молдовської та придністровської). Висвітлено досягнення ЄС у контексті розв’язання конфлікту.

Зроблено висновок, що у даному конфлікті були запропоновані вирішення суперечки з боку ЄС і країн-сусідів, зокрема й України та Російської Федерації. Коли при владі перебував проросійський режим, його вирішення постійно відтягувалось. Але, після перемоги проєвропейської партії «Дія та солідарність» на чолі з Маєю Санду, навколо Придністров’я знову почалась ескалація. Офіційно Молдова є нейтральною державою, проте російська військова присутність унеможливлює мирне розв’язання конфлікту. Головною перешкодою в цьому виступає вплив Кремля на Придністров’я та дислокування там великої кількості російських військовослужбовців.
Obama in the Americas: The Politics of Hope and Disappointment
Authors: Wilson Stacey-Ann
Published: August 2023

The aim of this article is to analyze what accounted for the hope Caribbean leaders and the general Caribbean population had regarding U.S. engagement in the region with the election of Barack Obama. The paper provides a brief analysis of Obama’s foreign policy in the Americas, with particular focus on the small island developing states in the Caribbean region. Utilising public discourse (online discussions and local news coverage), the paper explores the affection and the benefit of the doubt that was given to Obama as president, despite the historical asymmetrical relationship and experience of American foreign policy in the Caribbean and Latin America. The paper draws on the long history and experience of U.S. engagement in Latin America and the Caribbean broadly, but focuses on the smaller island nations of the Caribbean as they generally find themselves in more precarious economic, political, and social situations than their larger mainland counterparts. The paper also provides a review of some highlighted events in the region over the eight years of Obama’s presidency, including a discussion on the role of “blackness” in the Caribbean and the Caribbean Diaspora in the United States. The analysis shows that while the Caribbean harbors deep affection for Obama, his policies were no different from his predecessors. His policies toward the region were no more progressive or consultative or less hegemonic and dictatorial than previous American presidents. The affection and benefit of the doubt given to Obama had little to do with policies and more to do with “skinship” on the one hand and the dependent mindset of many Caribbean leaders on the other hand.

Molecular timetrees using relaxed clocks and uncertain phylogenies
Authors: Barba-Montoya Jose , Sharma Sudip , Kumar Sudhir
Published: August 2023

A common practice in molecular systematics is to infer phylogeny and then scale it to time by using a relaxed clock method and calibrations. This sequential analysis practice ignores the effect of phylogenetic uncertainty on divergence time estimates and their confidence/credibility intervals. An alternative is to infer phylogeny and times jointly to incorporate phylogenetic errors into molecular dating. We compared the performance of these two alternatives in reconstructing evolutionary timetrees using computer-simulated and empirical datasets. We found sequential and joint analyses to produce similar divergence times and phylogenetic relationships, except for some nodes in particular cases. The joint inference performed better when the phylogeny was not well resolved, situations in which the joint inference should be preferred. However, joint inference can be infeasible for large datasets because available Bayesian methods are computationally burdensome. We present an alternative approach for joint inference that combines the bag of little bootstraps, maximum likelihood, and RelTime approaches for simultaneously inferring evolutionary relationships, divergence times, and confidence intervals, incorporating phylogeny uncertainty. The new method alleviates the high computational burden imposed by Bayesian methods while achieving a similar result.
Comparison of Meta-Heuristic Optimization Algorithms for Global Maximum Power Point Tracking of Partially Shaded Solar Photovoltaic Systems
Authors: Nagadurga Timmidi , Devarapalli Ramesh , Knypiński Łukasz
Published: August 2023

Partial shading conditions lead to power mismatches among photovoltaic (PV) panels, resulting in the generation of multiple peak power points on the P-V curve. At this point, conventional MPPT algorithms fail to operate effectively. This research work mainly focuses on the exploration of performance optimization and harnessing more power during the partial shading environment of solar PV systems with a single-objective non-linear optimization problem subjected to different operations formulated and solved using recent metaheuristic algorithms such as Cat Swarm Optimization (CSO), Grey Wolf Optimization (GWO) and the proposed Chimp Optimization algorithm (ChOA). This research work is implemented on a test system with the help of MATLAB/SIMULINK, and the obtained results are discussed. From the overall results, the metaheuristic methods used by the trackers based on their analysis showed convergence towards the global Maximum Power Point (MPP). Additionally, the proposed ChOA technique shows improved performance over other existing algorithms.
Optimal Design and Control Performance Evaluation of a Magnetorheological Fluid Brake Featuring a T-Shape Grooved Disc
Authors: Turabimana Pacifique , Sohn Jung Woo
Published: August 2023

Magnetorheological fluid brakes are a promising technology for developing high-performance drive-by-wire braking systems due to their controllability and adaptability. This research aims to design an optimal magnetorheological fluid brake for motorcycles and their performance. The proposed model utilizes mathematical modeling and finite element analysis using commercial software. Furthermore, the optimization of this MR brake is determined through multi-objective optimization with a genetic algorithm that maximizes braking torque while simultaneously minimizing weight and the cruising temperature. The novelty lies in the geometric shape of the disc, bobbin, and MR fluid channels, which results in a light MR brake weighing 6.1 kg, an operating temperature of 89.5 °C, and a power consumption of 51 W with an output braking torque of 303.9 Nm. Additionally, the control performance is evaluated using an extended Kalman filter controller. This controller effectively regulates braking torque, speed, and slip rate of both the rear and front wheels based on road characteristics and motorcycle dynamics. This study’s findings show that the front wheel necessitates higher braking torque compared to the rear wheel. Moreover, the slip rate is higher on the rear wheel than on the front wheel, but the front wheel stops earlier than the rear wheel.

Published: August 2023

Rehabilitation of paralysis caused by a stroke or a spinal cord injury remains a complex and time-consuming task. This work proposes a hybrid exoskeleton approach combining a traditional exoskeleton and functional electrical stimulation (FES) as a promising method in rehabilitation. However, hybrid exoskeletons with a closed-loop FES control strategy are functionally challenging to achieve and have not been reported often. Therefore, this study aimed to investigate a powered lower-limb exoskeleton with a closed-loop FES control for Sit-to-Stand (STS) movements. A body motion capture system was applied to record precise hip and knee trajectories of references for establishing the human model. A closed-loop control strategy with allocation factors is proposed featuring a two-layer cascaded proportional–integral–derivative (PID) controller for both FES and exoskeleton control. Experiments were performed on two participants to examine the feasibility of the hybrid exoskeleton and the closed-loop FES control. Both open- and closed-loop FES control showed the desired performance with a relatively low root-mean-squared error (max 1.3∘ in open-loop and max 4.1∘ in closed-loop) in hip and knee trajectories. Notably, the closed-loop FES control strategy can achieve the same performance with nearly 60% of the electrical power input compared to the open-loop control, which reduced muscle fatigue and improved robustness during the training.

The electric solar wind sail, or E-sail, is a novel deep space propulsion concept which has not been demonstrated in space yet. While the solar wind is the authentic operational environment of the electric sail, its fundamentals can be demonstrated in the ionosphere where the E-sail can be used as a plasma brake for deorbiting. Two missions to be launched in 2023, Foresail-1p and ESTCube-2, will attempt to demonstrate Coulomb drag propulsion (an umbrella term for the E-sail and plasma brake) in low Earth orbit. This paper presents the next step of bringing the E-sail to deep space—we provide the initial modelling and trajectory analysis of demonstrating the E-sail in solar wind. The preliminary analysis assumes a six-unit cubesat being inserted in the lunar orbit where it deploys several hundred meters of the E-sail tether and charges the tether at 10–20 kV. The spacecraft will experience acceleration due to the solar wind particles being deflected by the electrostatic sheath around the charged tether. The paper includes two new concepts: the software architecture of a new mission design tool, the Electric Sail Mission Expeditor (ESME), and the initial E-sail experiment design for the lunar orbit. Our solar-wind simulation places the Electric Sail Test Cube (ESTCube) lunar cubesat with the E-sail tether in average solar wind conditions and we estimate a force of 1.51×10−4 N produced by the Coulomb drag on a 2 km tether charged to 20 kV. Our trajectory analysis takes the 15 kg cubesat from the lunar back to the Earth orbit in under three years assuming a 2 km long tether and 20 kV. The results of this paper are used to set scientific requirements for the conceptional ESTCube lunar nanospacecraft mission design to be published subsequently in the Special Issue “Advances in CubeSat Sails and Tethers”.

The formation process of starch in the grain is influenced by both genetic characteristics and environmental factors, which can affect starch quality. Waxy wheat Yangnuo1 (YN1) and non-waxy wheat Yangmai15 (YM15) were subjected to heat stress at the early, medium, and late grain-filling stages using artificial intelligence temperature control. Heat stress increased the short-chain content of amylopectin in both cultivars and decreased their amylose contents. The effect of heat stress on the wheat amylopectin structure was most pronounced 16–20 days after anthesis (DAA). The crystallinity and enthalpy of starch decreased, as did the swelling potential, solubility, and transmittance, but the retrogradation degree showed an opposite trend after heat stress. Compared with YM15, YN1 exhibited superior physical and chemical properties as well as anti-aging properties of starch and consequently had greater thermal stability under heat stress due to its higher degree of branching. The most sensitive stage to heat stress for yield was 6–10 DAA, which resulted in significant decreases in grain number and 1000-grain weight, followed by 16–20 DAA, which resulted in a significant decrease only in 1000-grain weight. Our study indicated that heat stress during the early stage of grain filling resulted in a decrease in both grain weight and yield, whereas during the middle stage of grain filling, it led to a decline in starch quality, especially in non-waxy wheat.

Published: August 2023

The important periodontal disease pathogen Porphyromonas gingivalis produces thick biofilms that increase its pathogenicity. Finding natural antimicrobial agents is crucial because of the rise in antibiotic resistance. The purpose of this study was to determine if plant extracts such as Symphytum officinale (S) and Panax Ginseng (G) were effective against P. gingivalis separately and in combination with a common antibiotic, metronidazole (F). Six different dilutions were produced using the plant extracts in different concentrations and antibiotics separately and in combination with F, G, and S using the two-fold serial dilution technique. To evaluate the effects of these substances, biofilm inhibition experiments were conducted. Plaque samples were collected from periodontitis patients to isolate P. gingivalis, and a standard strain of P. gingivalis (ATCC 33277) was purchased. Additionally, Acylated Homoserine Lactones (AHLs) detection was carried out to look for any activity that would interfere with quorum sensing. GraphPad Prism was used for statistical analysis with a p-value < 0.05. The combinations of Symphytum officinale and metronidazole (S+F) showed the maximum effectiveness in biofilm inhibition (98.7%), which was slightly better than G+F (98.2%), with substantial variations in biofilm inhibition levels in different treatment regimes. Notably, the patient isolate was more active than the standard strain. Additionally, the plant extracts and their combinations at particular dilutions had notable inhibitory effects on the generation of AHL (p < 0.05). The study highlights the possibility of Symphytum officinale and Panax Ginseng as effective treatments for P. gingivalis biofilm and AHLs, both on their own and in combination with metronidazole. These organic substances may open the door to cutting-edge methods of treating periodontal disorders.

Published: August 2023

Drain-associated intracerebral infections are life-threatening emergencies. Their treatment is challenging due to the limited penetration of antibiotics to the site of infection, resulting in potentially inadequate exposure. The emergence of multidrug-resistant pathogens might force the use of off-label intrathecal (IT) doses of antibiotics. We reviewed the literature on general aspects determining intrathecal dosing regimen, using pharmacometric knowledge. We summarised clinical experience with IT doses of antibiotics that are usually not used intrathecally, as well as the outcome of the cases and concentrations reached in the cerebrospinal fluid (CSF). Factors determining the IT regimen are the size of the ventricle system and the CSF drainage volume. With regard to pharmacometrics, pharmacokinetic/pharmacodynamic indices are likely similar to those in non-cerebral infections. The following number (N) of cases were described: benzylpenicillin (>50), ampicillin (1), ceftazidime (2), cephaloridine (56), ceftriaxone (1), cefotiam (1), meropenem (57), linezolid (1), tigecycline (15), rifampicin (3), levofloxacin (2), chloramphenicol (3) and daptomycin (8). Many side effects were reported for benzylpenicillin in the 1940–50s, but for the other antibiotics, when administered correctly, all side effects were minor and reversible. These data might help when choosing an IT dosing regimen in case there is no alternative option due to antimicrobial resistance.

Diabetes mellitus is recognized as the leading contributor to cardiovascular disease and associated mortality rates worldwide. Despite the use of pharmaceutical drugs to treat diabetes, its prevalence continues to rise alarmingly. Therefore, exploring remedies with a lower toxicity profile is crucial while remaining safe and effective in addressing this global public health crisis. Punica granatum Linn (pomegranate), known for its properties and safety profile, has been investigated in applied research and preclinical and clinical trials. However, conflicting reports still exist regarding its effects in diabetes. According to our knowledge, no systematic review has been conducted to critically analyze evidence from preclinical and clinical trials simultaneously, explicitly focusing on oxidative stress, inflammation, and endothelial function in diabetes. Therefore, in this systematic review, we searched for evidence on the impact of pomegranate in diabetes using databases such as PubMed, Scopus, and Google Scholar. Our inclusion criteria were limited to studies published in English. Of the 170 retrieved studies, 46 were deemed relevant and underwent critical analysis. The analyzed evidence suggests that pomegranate has the potential to alleviate oxidative stress, inflammation, and endothelial dysfunction in diabetes. Although a beneficial impact was noted in these markers, the endothelial function evidence still requires validation through further clinical trials with a powered sample size.

The progression of an abdominal aortic aneurysm (AAA) is an important issue, especially as AAA is becoming more common, and potentially life-threatening. This study aimed to understand better the mechanisms underlying AAA progression. For this purpose, we have focused on assessing the selected biomarkers whose potentially common denominator is the NRF2 (nuclear factor erythroid 2-related factor 2) transcription factor, that determines the selected antioxidant enzymes’ activation. The study group consisted of 44 AAA male patients (71.41 ± 7.80 years aged). They were divided into three groups based on the aneurism diameter: group I (below 55 mm), group II (between 55 and 70 mm), and group III (over 70 mm). The laboratory analyses of PON1 (paraoxonase-1), NRF2, and HO-1 (heme oxygenase 1) were performed based on commercial ELISA tests; Blb (bilirubin) and hsCRP (high sensitivity C-reactive protein) were assessed during routine morphology examinations after admission to the hospital. Multiple linear regression showed that both bilirubin and NRF2 determined the PON1 concentration in the entire study group. The correlations between the examined parameters within the three studied groups suggest the capitulation of NRF2-dependent antioxidant mechanisms to pro-inflammatory processes. We showed that HO-1 and hsCRP may play a crucial role in the development of inflammation aneurism progression. Moreover, in patients with medium-sized aneurysms, antioxidant mechanisms were depressed, and inflammatory processes began to dominate, which may lead to uncontrolled growth aneurysm rupture. Our study is one of the first to indicate that the chronically activated antioxidant pathway using NRF2 may be a source of reduction stress.

Published: August 2023

With an emphasis placed on a low-carbon economy, photovoltaic grid-connected inverters are moving toward the center of the stage. In order to address the problems related to the strong parameter dependence of the conventional model’s predictive control in grid-connected inverters, an improved parameter-free predictive current control is proposed. Relying on an extended state observer, an ultralocal model is employed to predict future currents without any parameters. The system can achieve a satisfactory performance in terms of dynamic response and robustness. Additionally, 30 virtual voltage vectors are extended for lower current ripples, which is followed by the use of a triangle candidate strategy to significantly ease the computing burden. In general, the proposed strategy omits parameter dependence, complex tuning work, and large tracking errors. The effectiveness of the proposed model is verified through the experimental results.

Published: August 2023

Identifying genes associated with autism spectrum disorder (ASD) is crucial for understanding the underlying mechanisms of the disorder. However, ASD is a complex condition involving multiple mechanisms, and this has resulted in an unclear understanding of the disease and a lack of precise knowledge concerning the genes associated with ASD. To address these challenges, we conducted a systematic analysis that integrated multiple data sources, including associations among ASD-associated genes and gene expression data from ASD studies. With these data, we generated both a gene embedding profile that captured the complex relationships between genes and a differential gene expression profile (built from the gene expression data). We utilized the XGBoost classifier and leveraged these profiles to identify novel ASD associations. This approach revealed 10,848 potential gene–gene associations and inferred 125 candidate genes, with DNA Topoisomerase I, ATP Synthase F1 Subunit Gamma, and Neuronal Calcium Sensor 1 being the top three candidates. We conducted a statistical analysis to assess the relevance of candidate genes to specific functions and pathways. Additionally, we identified sub-networks within the candidate network to uncover sub-groups of associations that could facilitate the identification of potential ASD-related genes. Overall, our systematic analysis, which integrated multiple data sources, represents a significant step towards unraveling the complexities of ASD. By combining network-based gene associations, gene expression data, and machine learning, we contribute to ASD research and facilitate the discovery of new targets for molecularly targeted therapies.
