Published: June 2023

The literature data of the last three decades on the problem of comorbidity of multiple sclerosis (MS) and epilepsy have been analyzed, such as issues of pathogenesis, clinical course, prognosis, and treatment of this dual pathology. Epileptic seizures occur in 2–3% to 5.9% of patients with MS, which is 3–6 times more common than in the general population. The incidence of epilepsy raises with increasing duration and severity of MS, with its progressive course, and also depends on the effect of drugs for the treatment of MS. There is no unanimity in the literature on the age and gender characteristics of the occurrence of epileptic seizures in MS. Probable mechanisms of MS comorbidity and epilepsy are analyzed. Data on certain common pathophysiology of MS and epilepsy and the concept according to which the model of epilepsy in MS is considered as a network disease are presented. Data on clinical manifestations and diagnosis of comorbid MS with epilepsy are presented. Epileptic seizures can occur at any stage of MS: before the clinical manifestations, at the onset of the disease, in the late stages, or can indicate exacerbation of MS. Types of epileptic seizures with a dual diagnosis (MS + epilepsy) are diverse. The majority of patients (up to 87.5%) have focal seizures (aware or unaware) or focal seizures to bilateral tonic-clonic, and a small share of patients have seizures of unknown origin. Most researchers believe that patients with MS and epilepsy have a more severe MS course and a worse long-term prognosis. The main directions of MS treatment and the impact of such treatment on the development of epileptic seizures are highlighted. Data on the effect of some disease-modifying drugs for the treatment of MS on the course of epilepsy and, on the other hand, on the impact of some antiseizure medications on the course of MS are presented. It is concluded that patients with MS have individual profiles and inter-individual variability of epileptogenicity. The principles of treatment of epileptic seizures/epilepsy in patients with MS are proposed.

Authors: Bezhuk Yuliya , Martovlos (Hodovana) Olesia
Published: June 2023

Decamethoxine (DCM®) is a substance from a group of quaternary ammonium compounds. According to literary sources, the antimicrobial effect is due to a mechanism that combines damage to the cell membrane of bacteria and lysis of their protoplasts, as well as changes the permeability of the microbial cell membrane, causing its destruction. DCM® demonstrates activity against gram-positive and gram-negative bacteria (staphylococci, streptococci, diphtheria and Escherichia coli, salmonella, proteus, klebsiella, shigella, pseudomonads, clostridia), some fungi (yeast fungi, mold fungi). There are also reports of the antiviral activity of this compound. The purpose of this study was to highlight the results of the current work of Ukrainian scientists and analyze the properties and broad aspects of DCM® antiseptic, as well as demonstrate their clinical case for its effectiveness in periodontal practice. The analysis of the results of various publications allowed us to evaluate the full range of DCM® properties in terms of its therapeutic potential in modern preclinical and clinical studies, particularly in periodontal practice.

Authors: Besh Dmytro , Besh Olesia
Published: June 2023

The article presents the features of the morphologic structure of intracoronary thrombi and the prognosis of acute ST segment elevation myocardial infarction (STEMI) in patients of different age groups.

Methods: Histological analysis of the aspirated intracoronary clots was performed in 97 patients with STEMI. The patients were divided into two groups: 11 patients aged under 44 (young group) and the remaining older than 45 (older group). The short-term prognosis was determined by: ST-segment resolution, achievement of good coronary flow, myocardial blush, indices of myocardial contractility, and QS wave formation on ECG. The study’s endpoints determined the long-term prognosis: The onset or worsening of angina symptoms, coronary revascularization (PCI or CABG), AMI, and death.

Results: Elderly patients were substantially more likely to have a history of coronary artery disease, as well as angina attacks, or their equivalents, at rest a few days before the onset of STEMI and arterial hypertension. Dyslipidemia was significantly more common in young patients. Formation of microchannels within the thrombi was significantly more common among older patients. Achieving the target quality of microcirculation was substantially more frequent among young patients (p=0.007). The long-term prognosis was better in young patients due to the lower prevalence of the combined endpoint.

Conclusions: Elderly patients were more likely to have intracoronary thrombi with microchannel formation, indicating a longer duration of the thrombotic process. The long-term prognosis after STEMI was significantly better in young patients.

Authors: Jasim Nadal Adnan , Ibrahim Abdulrahman Adnan , Hatem Wadhah Amer
Published: June 2023

Many oil and gas projects have been subjected to significant cost overruns and schedule delays, which is a major concern for the decision-makers in the oil industry. This paper aims to develop three mathematical models to estimate earned value indicators, the Schedule Performance Index (SPI), Cost Performance Index (CPI), and To-Complete Cost Performance Indicator (TCPI), to reduce the cost and time estimation error in Iraqi oil projects. The research methodology adopted artificial intelligence techniques using Multiple Linear Regression technology (MLR) to predict Earned Value (EV) Indexes to get standard local equations to measure the performance of Iraqi oil projects. The data is based on (83) monthly reports from 26 June 2015 to 25 August 2022 collected from the Karbala Refinery Project, selected as a case study. It is one of the Oil Projects Company (SCOP)- the Iraqi Ministry of Oil’s massive and modern projects, and it combines several projects into one project. The results showed numerous significant points, such as the average accuracy (AA%) for the CPI, SPI, and TCPI was 95.194%, 92.195%, and 83.706%, respectively, while the correlation coefficients (R) were 92.4%, 98.4%, and 93.7%. It was shown that there were relatively few differences between the theoretical and actual results. Therefore, the MLR technique was utilized in this paper to derive the prediction models for its more correct earned value predictions.

Authors: Fathony Alvan , Mahyah Jamilatul
Published: July 2023

Islamic banking, as the main figure in the Islamic financial institution, strives to become an intermediary institution in incorporating Islamic finance into salt traders. Salt farmers who enter into a cooperation agreement (mudarabah) will share the proceeds at a later date according to the agreed-upon terms, where the landowners will receive 75% of the sales proceeds and 25% will be allocated to the land workers. This study aims to determine the role of Islamic banking in empowering small and medium-sized enterprises (SMEs) of salt traders. The rising prices of salt in the market will result in a depletion of salt stock in the warehouses and require a significant amount of capital. Traders will need a substantial amount of working capital to meet the demands of their businesses. They will borrow the necessary capital according to their needs, to repay it by the agreed-upon terms. This research utilizes a qualitative descriptive method, and the primary data used in this study are obtained through a literature review and interviews. The instrument used for collecting primary data is interviews conducted with salt trader community members in Galis Pamekasan. They revealed that Islamic banking also plays a role in the development of salt trader SMEs by assisting in the implementation of government programs such as the People's Business Credit (KUR), financing distribution, profit sharing, and savings and loans.

Published: June 2023

Background:

Carotid artery stenosis and coronary artery disease (CAD) often occur simultaneously, with one being an important risk factor in the treatment of the other. This study aimed to perform coronary computed tomography angiography (CTA) as a preoperative evaluation for carotid artery stenosis treatment.

Methods:

We retrospectively reviewed cases of carotid endarterectomy (CEA) and carotid artery stenting (CAS) performed at our hospital as well as CAD complications.

Results:

Among the 54 and 166 CEA and CAS cases from May 2014 to February 2022, 53 and 148 cases were analyzed for atherosclerotic stenosis, respectively. Among those who underwent CEA and CAS, 7 (13.2%) and 17 (11.5%) received percutaneous coronary intervention (PCI), 44 (83%) and 97 (65.5%) received symptomatic carotid stenosis treatment and 43 (81.1%) and 110 (74.3%) received preoperative coronary CTA, respectively. Coronary artery stenosis was noted in 14 (32.6%) and 46 (41.8%) patients who had undergone CTA in the CEA and CAS groups, respectively. PCI before carotid treatment was performed in two cases in the CEA group (3.8% of all patients who had undergone CEA) and eight cases in the CAS group (5.4% of all patients who had undergone CAS).

Conclusion:

Screening may detect asymptomatic coronary artery lesions in carotid artery stenosis even in patients without chest symptoms and suspicion of ischemic heart disease. Preoperative coronary artery screening is important considering that pre and postoperative coronary artery treatment may improve long-term prognosis.

Authors: Hendarsyah Milwan , Nurjani Nurjani , Basuni Basuni
Published: July 2023

Sawi pakcoy (Brassica rapa subsp. Chinensis) merupakan jenis sayuran sawi-sawian yang termasuk dalam family Brassicaceae. Budidaya sawi pakcoy dapat dilakukan secara hidroponik untuk memaksimalkan potensi hasil. Selain itu hidroponik mampu menghasilkan produk yang berkualitas dan bersih serta bebas dari pestisida sehingga digemari oleh  masyarakat. Produksi sawi pakcoy pada sistem hidroponik dapat dimaksimalkan dengan meningkatkan konsentrasi nutrisi yg diberikan, namun jika konsentrasi diberikan terlalu tinggi dapat membuat tanaman keracunan dan terganggu pertumbuhannya serta meningkatkan biaya akibat penambahan nutrisi, sementara itu giberelin diduga berperan meningkatkan pertumbuhan dan hasil tanaman melalui percepatan pembelahan sel, sehingga pengaplikasian giberelin diharapkan mampu meningkatkan hasil sawi pakcoy yang didukung dengan jenis nutrisi yang tepat. Adapun tujuan penelitian ini yaitu mencari konsentrasi giberelin yang terbaik, mengetahui jenis nutrisi yang terbaik serta mengetahui pengaruh interaksi antara konsentrasi giberelin dan jenis nutrisi untuk pertumbuhan dan hasil sawi pakcoy pada hidroponik sumbu. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 3 ulangan.  Faktor pertama yaitu konsentrasi giberelin (g) dengan 3 taraf perlakuan yaitu 0, 50 dan 100 ppm. Faktor kedua adalah jenis nutrisi (n) dengan 3 taraf perlakuan yaitu Goodplant, racikan 1 dan racikan 2. Hasil uji keragaman menunjukkan terdapat pengaruh nyata interaksi antara giberelin dan jenis nutrisi pada luas daun 2 MST. Pada perlakuan konsentrasi giberelin memberikan pengaruh nyata terhadap tinggi tanaman, luas daun usia 2 MST, volume akar dan berat segar tajuk tanaman. Adapun pada perlakuan jenis nutrisi memberikan pengaruh nyata terhadap jumlah daun pada usia 4 MST, luas daun usia 3 dan 4 MST, volume akar dan berat segar tajuk tanaman. Berdasarkan Uji Duncan, diketahui bahwa interaksi berpengaruh nyata antara perlakuan konsentrasi giberelin dan jenis nutrisi terhadap tanaman sawi pakcoy yaitu pada luas daun usia 2 MST, pemberian konsentrasi giberelin 0 ppm (tanpa giberelin) pada jenis nutrisi racikan 1 merupakan perlakuan terbaik. Pengaplikasian giberelin memberikan pengaruh nyata terhadap pertumbuhan, namun berpengaruh tidak nyata terhadap hasil. Sedangkan perlakuan jenis nutrisi, pada jenis nutrisi racikan 2 merupakan terbaik terhadap luas daun 3 dan 4 MST, sama baiknya dengan nutrisi racikan 1 terhadap volume akar dan berat segar tajuk tanaman.

Methyl groups play a vital role in pharmaceutical substrates, where their installation onto aryl and heteroaryl moieties can often lead to enhanced drug-target interactions. This phenomenon has been termed the “magic methyl effect”, and it has become an important tool for the improvement of therapeutic potency during lead optimization stages in drug development. Herein, we report a new methodology for the methylation of various phenols as tosylates as well as aryl halides via a hydrazone-mediated Ni-catalyzed cross-coupling by introducing a new bench-stable methylating reagent in the form of formaldehyde hydrazone. The reaction produces moderate to good yields on a structurally diverse set of aryl and heteroaryl electrophiles. Experimental and computational investigations were carried out to support the proposed mechanism for this reaction.

Published: June 2023

In the manuscript the application of dearomative normal-electron-demand aza-Diels-Alder cycloaddition in the synthesis of tetrahydrofuropyridines is described. The developed approach utilizes aminocatalytic activation of 2-alkyl-3-furfurals that proceeds via formation of dearomatized dienamine intermediate. Initially obtained cycloadducts have been subjected to subsequent transformations providing access to tetrahydrofuropyridines or functionalized cinnamates indicating the potential of the developed methodology. The mechanism of the process has been confirmed by DFT calculations.
Carbon–Carbon Bond Activation by Main-Group Metal Complexes
Authors: Parr Joseph , Crimmin Mark
Published: June 2023

Examples of carbon-carbon bond activation reactions at main-group metals (e.g. Mg, Al, Zn, Sn) are described in this review. Key approaches are discussed, and divergent reactivity compared to transition metal complexes highlighted. Several distinct mechanisms for C–C bond activation at main group metals have been proposed, with the key C–C bond activation step occurring by (i) beta-alkyl elimination, (ii) alpha-alkyl elimination, (iii) oxidative addition, or (iv) an electrocyclic reaction. Many of the known pathways involve an overall 2-electron redox process. Despite this, the direct oxidative addition of C–C bonds to main group metals is relatively rare, instead most reactions occur through initial installation of the main group site on a hydrocarbon scaffold (e.g. by a cycloaddition reaction or hydrometallation) followed by an -alkyl or -alkyl elimination step. Emerging applications of main group metal complexes as catalysts for the functionalisation of C–C bonds are also discussed.
Features of vortex trace propagation for aircraft with propellers
Authors: Zhelannikov A. I.
Published: June 2023

The article presents the results of a study of the characteristics of the wake vortex of aircraft with turboprop engines. Using the example of the An-12 aircraft, it is shown that rotating propellers make a noticeable contribution to the propagation of the vortex trail behind the aircraft. This is proved by some studies, as well as numerous observations. It also describes a technique for studying the wake vortex of aircraft with propellers. The method is based on the method of discrete vortices. The relevance of such studies is due to the growing interest of carrier companies in aircraft with turboprop engines. It has been proven that when transporting passengers and cargo on such vessels over distances of 700–800 km, maintenance and fuel costs are reduced by about 30–40%. Therefore, the fleet of turboprop aircraft, such as An-22, An-70, An-12, as well as Tu-95, Il-38, C-130, etc., has been preserved so far. New turboprop aircraft are being developed and put into operation: A-400M, Il-114, Il-112M. The vortex trail behind such aircraft also poses a danger to other aircraft flying behind. A feature of the propagation of the wake vortex behind aircraft with propellers is the interaction of vortices coming off the airframe and vortices from the propellers. As a result, due to the rotation of all the screws in one direction, symmetry is broken in the propagation of vortices descending from the right and left halves of the wing. Therefore, it is important to understand how differently the vortices that descend from the airframe of an aircraft with turboprop engines behave. For the convenience of the study, the method of accounting for the effect of vortices from screws is integrated into a special calculation and software package, also based on the method of discrete vortices. In it, when calculating the characteristics of the wake vortex, the flight weight, speed and altitude of the aircraft, its flight configuration, atmospheric conditions, proximity of the earth, axial velocity in the core of the vortex and some other factors are taken into account. This complex has passed the necessary testing and state registration. A number of measures were carried out to validate and verify the developed complex, confirming the operability of the programs included in it and the reliability of the results obtained from it. The results of the study of the characteristics of the wake vortex behind the Antonov-12 aircraft in the form of vertical velocity spectra and fields of perturbed velocities at various distances from it are presented. It is shown that propellers noticeably affect the propagation of the wake vortex behind turboprop aircraft. This circumstance must be taken into account by the crews of aircraft flying behind such aircraft.
'A Little Kind of Island'

This chapter discusses the experience of Doncaster, a city in the North of England, from the perspective of engaged members of the community. The city has experienced a range of crises, including deindustrialization, flooding, local government corruption, and the UK's decision to leave the European Union. The article examines how these crises impact the community and how community members view and respond to them. The authors argue that crises are not evenly distributed and instead are located in particular places and that the ability of a single community to manage the threats posed by the configuration of hazardscape is restricted. They also highlight the importance of considering the distinction between rapid and slow-onset hazards and the connection between disparate sources of risk.
From Migrant Crisis to Migrant Critique
Authors:   University of York, Jong, de Sara
Published: June 2023

This chapter discusses the reframing of the "refugee crisis" by critical scholars, who argue that the crisis was not brought to Europe by refugees but rather exposed existing fault lines in European institutions and values. The author argues that it is essential to complement these conceptualizations with migrants' own understandings of crisis and draws on interviews with local Afghan interpreters who worked for Western armies to explore their crisis experiences and critiques of European values. The author argues that migrants' diagnoses of converging crises and the comments linked to these inform their agentive social responses. This enables migrants to adopt a strategy of 'affirmative sabotage' based on a simultaneous appeal to and critique of European values. The article seeks to foreground the voices and actions of migrants and challenge a framing of crisis that reproduces a division of labour between migrants and refugees and states, governments, and European institutions.

Published: June 2023

Background/ObjectiveHypertension, “the silent killer,” is an important preventable cause of premature morbidity and mortality globally. This condition has become a major non-communicable disease threatening sub-Saharan Africa, and its prevalence is rising in middle and low-income countries. This study objective was to determine the prevalence and predictors of hypertension among company workers in Rivers State, NigeriaMethodsThis analytical and cross-sectional study used a multi-stage sampling technique to recruit 296 company workers in Rivers State, Nigeria. A semi-structured questionnaire was used to obtain the respondents’ demographics, lifestyle, and healthcare characteristics. Respondents’ weight and height were measured using standard procedures. Blood pressure was determined by standard practice and criteria as defined by WHO and International Society of Hypertension. Data were analyzed using descriptive statistics, correlation, and logistic regression at p< 0.05 level of significance.Results64.9% of the respondents were married and 59.5% were male. 52.0% drank alcohol, and 7.4% smoked. While 67.2% claimed they were not hypertensive, 22.6% don’t know their blood pressure status, and 58.1% were physically inactive. The prevalence of hypertension was 33.4%, and the prevalence of overweight and obesity was 43.6% and 15.2%, respectively. Predictors of hypertension in the study population were sex (male) (p<0.001), age >40 (p<0.001), alcohol consumption (any) (p<0.05), physical activity (≤rarely) (p<0.001) and BMI (≥25) (p<0.001) of the respondents.ConclusionThere was a high prevalence of hypertension and presence of modifiable cardiovascular disease risk factors among the population. Therefore, both secondary and primary prevention require attention, in the latter case, comprehensive population-wide and workstation interventions, including behavioral change and communication interventions that are context-specific, should be implemented.
An Overview of Mobility Management Mechanisms and the Related Challenges in 5G Networks and Beyond

Published: June 2023

Ensuring a seamless connection with various types of mobile user equipment (UE) items is one of the more significant challenges facing different generations of wireless systems. However, enabling the high-band spectrum – such as the millimeter wave (mmWave) band – is also one of the important factors of 5G networks, as it enables them to deal with increasing demand and ensures high coverage. Therefore, the deployment of new (small) cells with a short range and operating within the mmWave band is required in order to assist the macro cells which are responsible for operating long-range radio connections. The deployment of small cells results in a new network structure, known as heterogeneous networks (HetNets). As a result, the number of passthrough cells using the handover (HO) process will be dramatically increased. Mobility management (MM) in such a massive network will become crucial, especially when it comes to mobile users traveling at very high speeds. Current MM solutions will be ineffective, as they will not be able to provide the required reliability, ﬂexibility, and scalability.Thus, smart algorithms and techniques are required in future networks. Also, machine learning (ML) techniques are perfectly capable of supporting the latest 5G technologies that are expected to deliver high data rates to upcoming use cases and services, such as massive machine type communications (mMTC), enhanced mobile broadband (eMBB), and ultra-reliable low latency communications (uRLLC). This paper aims to review the MM approaches used in 5G HetNets and describes the deployment of AI mechanisms and techniques in ″connected mode″ MM schemes. Furthermore, this paper addresses the related challenges and suggests potential solutions for 5G networks and beyond.
