Authors: Issa Lotfi , Alfaqih Mohammed , Aljuaid Waleed , Alamri Mohammed , Alalyani Osama , Alhumaidi Abdulaziz , Alazwari Khalid
Published: September 2022

Background: The symptoms of peptic ulcer (PU) are hard to distinguish from symptoms of other gastrointestinal tract (GIT) disorders. Thus, demonstrating the gaps in knowledge might minimize the risk of PU. The study aimed to assess the Saudi population's knowledge, awareness, and practices regarding the risk factors of PU.
Methods: A cross-sectional observational, survey-based study was conducted among Saudi adults in Taif.
Results: Thirty-six of the participants were aged 18-30 years, 60.1% were males, 61.0% were married, 50.3% were employed, and 94.2% were Saudi. Around 67.8% of the participants were University graduates. The most used medications were paracetamol (32.4%), antibiotics (28.4%), and aspirin/non-steroidal anti-inflammatory drugs, 16.6%. The median practice score was 7 out of 14 points. Significantly higher median practice scores were observed among participants aged more than 40 years (p-value < 0.001), male participants (p-value < 0.001), unemployed (p-value < 0.001), and participants with chronic diseases (p-value 0.007), while lower scores were reported among single participants (p < 0.001). The median knowledge score was 10 out of 31 points. Significantly higher median knowledge scores were observed among participants aged 18 to 30 years (p-value 0.046), single and widowed participants (p-value 0.036), students/interns (p-value 0.002), and participants with a family history of GIT disorders (p-value < 0.001).
Conclusion: Knowledge and practice among the Saudi population regarding PU were inadequate. Educational programs are needed to raise the Saudi population's awareness of PU to prevent and ensure the best patient outcomes.
The Understanding of the History of Ablaut in Russian and its Pedagogical Application
Authors:   Institute for Russian and Altaic Studies, CBNU, Kim Hyoung Sup
Published: September 2022

This study examines the vowel-gradation/ablaut in Russian, i.e., the consistent changes of a root vowel within the structure of CVC, where occurs a series of changes of normal /e/ in the process of a qualitative or quantitative change, that is, according to the change of the normal vowel /e/, there occur many vowel-gradation/ablaut in Russian.: o-grade ( /e/ > /o/), e-grade (/ø/ or weak vowel /ь/ > /e/), zero-grade or reduced grade (by dropping a vowel > /ø/), or lengthened/long grade (quantitatively lengthening a vowel, /e/ > /ē/ or /ō/, so-called, lengthened/long e-grade and lengthened/long o-grade, respectively.
The Russian ablaut provides grammatical information or linguistic characteristics, which is productive or at least marginally productive in Russian conjugation, aspectual minimal pairs, verbal or nominal derivation, etc., for cognate words. For example, cognate words have a series of vowel-gradation, which categorizes grammatical distinctions as follows: со-бр-а-ть (pf.) - со-бир-а-ть (impf.) ‘to collect’ - бер-у ‘I take’, бер-ёшь ‘you take’, бер-ут ‘they take’ - со-бор ‘synod’, с-бор ‘assembly’, etc. These cognates represent vowel-alternations of /ø/ ≈ /и/ ≈ /е/ ≈ /о/ with the distinction of grammatical information, such as perfective vs. imperfective, verbal vs. nominal, infinitive vs. conjugated form.
Moreover, Russian vowel-gradation can apply to pedagogical use. Understanding a systematic vowel change, namely, ablaut, can help L2 learners of Russian maximize the effect of learning Russian cognate words with grammatical and linguistic information. From a perspective of pedagogy, the Russian ablaut informs L2 learners of a series of cognate words, which belong to another language group, such as Germanic or Italian group, etc. as well as Slavic group. For this reason, it is useful for L2 learners to understand the Russian ablaut.

Authors:   Institute for Russian and Altaic Studies, CBNU, Byun Hyun Sub , Jeon Myong Su
Published: September 2022

In this paper, derived implications for Korea-Russia cooperation by analyzing the trends in the participation of Western and Japanese companies in sanctions against Russia in the Russian Far East after Russia’s invasion of Ukraine, their impact on Russia, Russia’s countermeasures, and Russia-China cooperation cases. and proposed policy tasks for cooperation with Russia to the new government of Korea. Four policy implications were emphasized as follows. First, it is necessary to review the participation of Korean companies in the businesses that Western and Japanese companies have withdrawn and target niche markets. Second, in the case of sanctions items, since direct trade with Russia is difficult, bypass exports through China and Central Asian countries should also be considered. Third, cooperation with Russia should be resumed as soon as possible, even in areas not related to sanctions. Fourth, communication and exchange for cooperation at the level of private companies and local governments should be continued while continuously managing human networks with local related organizations and high-level officials, including the Russian Far East.
M.A. Bulgakov and the “Kiev text”: Based on the “Kiev-gorod” and “The White Guard”
Authors:   Institute for Russian and Altaic Studies, CBNU, Kang Su Kyung
Published: September 2022

The article is devoted to the problem of “Kiev text”. The author analyses two works of M.A. Bulgakov, created and completed after visiting to his hometown of Kyiv in 1923, the sketch “Kiev-gorod” and the novel “The White Guard”. To this end, at first, we examined the research history and research trends of “Kiev text” in Russian literature , and revealed the characteristics of “Kiev text”.
We also saw that in “Kiev-gorod” and “The White Guard” the figure of Kyiv is depicted in ‘history’ as the image of falling Babylon, in the memory of the lyrical self and in Alexei’s dream as the image of the heavenly Jerusalem.
As such, the myth of the confrontation between these two cities is the basis of Bulgakov's “Kiev text”. Meanwhile, Bulgakov's ‘city’, which contains an eternal ‘culture’ that is not destroyed by any ‘history’, is unique in that it has myth and eternity.
In this way, this paper ultimately tried to find the literary meaning of the Bulgakov ‘s “Kiev text”, and to read the most famous “Kiev text” of the 20th century, “The White Guard” and its documentary version, “Kiev-gorod”, from a new perspective.

Authors: Tsutsumi Satoshi , Kuroda Kiyotaka , Sugiyama Hiroki , Sugiyama Natsuki , Ueno Hideaki , Ishii Hisato
Published: September 2022

Background:

Subsequent bilateral intracerebral hemorrhage (SBICH) in the putamen and thalamus is a rare condition. Herein, we report four such cases.

Case Description:

Case 1: A 47-year-old woman presented with the left hemiparesis and elevated blood pressure. Neuroimaging revealed a right thalamic hemorrhage and a small left thalamic hemorrhage accompanying the hyperdense rim on computed tomography (CT) and the hypointense rim on gradient-echo T2*-weighted imaging (T2*WI). Case 2: A 53-year-old man presented with a disturbance of consciousness and elevated blood pressure. Neuroimaging revealed a left putaminal hemorrhage and a small right thalamic hemorrhage that appeared hyperdense on CT and hypointense on T2*WI. Case 3: A 65-year-old woman presented with the right hemiparesis and elevated blood pressure. Neuroimaging revealed a left putaminal hemorrhage and a small right thalamic hemorrhage accompanied by a hyperdense rim on CT and a hypointense rim on T2*WI. Case 4: A 75-year-old woman presented with the right hemiparesis and elevated blood pressure. Neuroimaging revealed a left thalamic hemorrhage and small hemorrhages in the right thalamus and cerebellar hemisphere. These hemorrhages appeared hyperdense on CT and hypointense on T2*WI.

Conclusion:

SBICHs are rare bilateral hemorrhages that may present with asymptomatic microbleeds in the putamen or thalamus coupled with symptomatic, subsequent hemorrhages in the contralateral counterparts. The latter hemorrhage may develop during the subacute phase of microbleeds in the putamen or thalamus.

Authors: Shah Darsh S. , Sharma Himanshu , Patel Prem , Shetty Arya , English Collin William , Goodman J. Clay , Viswanathan Ashwin , Patel Akash J.
Published: September 2022

Background:

Liponeurocytomas are rare neurocytic neoplasms that most often arise in the posterior fossa and affect individuals in the third and fifth decades of life. Most reported cases of this unique tumor in the literature have described a favorable clinical prognosis without recurrence. However, increasing reports of recurrent cases prompted the World Health Organization, in 2016, to recategorize the tumor from Grade I to the less favorable Grade II classification. We conducted a systematic review to identify recurrent cases of this unique tumor and to summarize differences between the primary and recurrent cases of liponeurocytoma.

Methods:

A systematic review exploring recurrent liponeurocytoma cases was conducted by searching the PubMed, Google Scholar, and Scopus databases for articles in English. Abstracts from articles were read and selected for full-text review according to a priori criteria. Relevant full-text articles were analyzed for symptoms, imaging, location, histological, pathological, treatment, and recurrence-free time between the primary and recurrent cases.

Results:

Of 4392 articles, 15 articles accounting for 18 patients were included (level of evidence: IV) in the study. Recurrence-free time decreased from an average of 82 months between the primary tumor resection to first recurrence to 31.3 months between the first and second recurrence. Recurrent tumors demonstrated increased pleomorphic neural cells, necrosis, vascular proliferation, and MIB-1 index when compared to the primary tumor. Several cases also demonstrated decreased lipidizing components when compared to the primary tumor, further indicating increased dedifferentiation. The primary treatment for this tumor was surgical resection with occasional adjunctive radiotherapy.

Conclusion:

Recurrent cases of liponeurocytoma have features of increased malignant proliferation compared to the primary cases. The standard treatment for these primary and recurrent tumors is gross total resection. The role of adjunctive radiotherapy remains a matter of debate.
Recurrent glioblastoma in elderly: Options and decision for the treatment
Authors: Prajapati Hanuman Prasad , Singh Deepak Kumar
Published: September 2022

Background:

Glioblastoma (GBM) is the most common primary malignant brain tumor in adult. Its incidence increases with age and nearly half of the all newly diagnosed GBM cases are older than 65 years. Management of GBM in elderly is challenging and recurrence poses further challenge. This article aims to review the literature, evaluate the various options, and to decide the treatment plan in elderly cases with GBM recurrence.

Methods:

A systemic search was performed with the phrase “recurrent GBM (rGBM) in elderly and management” as a search term in PubMed central, Medline, and Embase databases to identify all the articles published on the subject till February 2022. The review included peer-reviewed original articles, review articles, clinical trials, and keywords in title and abstract.

Results:

Out of 473 articles searched, 15 studies followed our inclusion criteria and were included in this review. In 15 studies, ten were original and five were review articles. The minimum age group included in these studies was ≥65 years. Out of 15 studies, eight studies had described the role of resurgery, four chemotherapy, three resurgery and/or chemotherapy, and only one study on role of reradiotherapy in patients with rGBM. Out of eight studies described the role of resurgery, six have mentioned improved survival and two have no survival advantage of resurgery in cases of rGBM.

Conclusion:

Resurgery is the main treatment option in selected elderly rGBM cases in good performance status. In patients with poor performance status, chemotherapy has better post progression survival than best supportive care.

Authors: Sano Noritaka , Ikeda Hiroyuki , Tsujimoto Yoshitaka , Hayase Makoto , Torikoshi Sadaharu , Morikawa Taiyo , Okoshi Tadakazu , Nishimura Masaki , Toda Hiroki
Published: September 2022

Background:

Ruptured intracranial fungal mycotic aneurysms have a high mortality rate. It has been reported that the number of opportunistic infections has increased. Here, we report the first case of a patient in which a ruptured fungal carotid artery aneurysm was successfully treated by stent-assisted coil embolization.

Case Description:

A 76-year-old male receiving dual antiplatelet therapy due to a recent percutaneous transluminal angioplasty presented with blurred vision of the right eye and diplopia. Magnetic resonance imaging revealed a fungal mass in the sphenoid sinus, and the patient was pathologically diagnosed with invasive aspergillosis. After receiving oral voriconazole for 4 weeks, he was admitted to the hospital with hemorrhagic shock from epistaxis. The right internal carotid artery angiography revealed ade novoirregularly shaped aneurysm at the cavernous portion, projecting into the sphenoid sinus, which was considered to be the source of bleeding. Due to the lack of ischemic tolerance and urgent demand for hemostasis, we performed a stent-assisted coil embolization of the aneurysm without interrupting the blood flow. Postoperatively, the patient had no neurological deficit, and treatment with voriconazole was continued for 12 months without rebleeding.

Conclusion:

Stent-assisted coil embolization without parent artery occlusion might be a promising option for the urgent treatment of ruptured fungal mycotic aneurysms. Long-term administration of voriconazole might be continued for 12 months for such patients.

Authors: Bala Kiran , Kumar Vikas , Kharor Neeraj , Singh Jasbir
Published: September 2022

C5L2 (C5aR-like receptor 2) is a G protein coupled receptor involved in glucose transport, esterification of fatty acids and triacylglycerides synthesis. Association studies have been conducted for evaluation of relation between C5L2 gene polymorphisms and T2DM but results could not be concluded because of ambiguous findings. Therefore, current study was planned on North Indian population to investigate the association of single nucleotide polymorphism (SNP) of C5L2 gene at position 698 (C>T) with type 2 diabetes mellitus (T2DM). Genomic DNA was isolated from blood samples collected from 102 healthy control subjects and 168 T2DM cases and stored at -20°C for further analysis. Polymerase chain reaction (PCR) was performed in all the DNA samples using specific primers followed by restriction fragment length polymorphism (RFLP) and results were analyzed on agarose gel. Clinical parameters like glycosylated hemoglobin (HbA1c), fasting blood glucose (FBG), high density lipoprotein cholesterol (HDL-C), triglycerides (TG), total cholesterol (CHL) and fasting insulin were determined by enzymatic methods. Statistically significant association was observed between C5L2 gene at SNP rs149572881 and T2DM and frequency of the T allele was significantly higher in T2DM cases as compared to controls subjects [C vs. T, OR (95%CI) = 5.15(1.53-17.34), P=0.003]. It can be concluded from the results that the T allele at position 698 of C5L2 gene might be a risk factor for development of T2DM in North Indians.
Structural binding analysis of native and mutant Nomascus Acetyl CoA binding proteins using in silico methods
Authors: Harish T.S. , Ramesh Babu P.B.
Published: September 2022

Acyl-CoA binding protein (ACBP) having molecular weight of 10kDa is known to bind to C12-C22 acyl-CoA esters. The ACBP proteins are highly conserved across phylum as their homologues have been identified in all four eukaryotic kingdoms and 11 species of eubacteria most of which are pathogenic. The 3-D structures of some ACBPs were determined using X-ray crystallography and NMR spectroscopy, which showed four -helices fixed in a skew shape with acyl-CoAbinding site. Using in silico method Clustal W, we identified five residues. These residues are point mutated modeled by using Discovery Studio software to analyze static structural properties as well as dynamic behavior with respect to wild type, using GROMACS software for molecular dynamic simulations. In present study, we modeled acbp mutants (ala36-> gly) computationally and analyzed structure properties with molecular dynamics tools and analyzed parameters like RMSD, RMSF, radius of gyration, H-bond. We performed docking studies with myristyl and palmityl CoA with different docking tools and observed significant binding energy in both ligands indicating that mutation doesn’t affect any property of modeled ACBP protein.

Published: September 2022

Diabetes Mellitus (DM) is a chronic disease due to elevated level of blood glucose which can lead to complications in many parts of the body. International Diabetes Federation has estimated that DM patient numbers will increase to 123.5 million by 2040. Diabetes and its complications include blindness, nerve damage, heart attack and kidney failure and they depended on the biochemical and immunological parameters. The candidate genes were playing a vital role in the development of DM. The prime aim of the study was to examine the clinical, biochemical, chromosomal and micronuclei frequency in Diabetes Mellitus patients. In the present study, 120 experimental and 120 controls subjects were recruited, they were further divided in to two groups in accordance with the age and disease duration. Peripheral blood samples were used to analyze the clinical and cytogenetic parameters. Result of the study was analyzed based on various clinical parameters. It is found that the total cholesterol level and micronuclei frequency were significantly higher compared to the controls and insignificant levels of creatinine and chromosome damages were found in higher disease duration type of diabetic patients. The assessments of clinical, biochemical and chromosomal alterations indicate the risk of organ failure and the higher value was influenced by the duration of disease.

Published: September 2022

Rubus niveus (Kala Hisalu) is an economically value-added wild edible berry of the Kumaun Himalayan region. Human beings consume it as a vital source of nutraceuticals leading to increase its additional value. Present study is focused on the comparative analysis of phytoconstituents, free radical scavenging activity and nutrient and anti-nutritional composition of R. niveus berries in two different solvent system i.e. ethanol and water. The in vitro free radical scavenging activity has been investigated by three different assays i.e. DPPH, H2O2 and NO and propounded that ethanolic extracts consist of more active constituents to scavenge different stable and generated radicals than aqueous extracts. This analysis is also supported by the phytochemical studies (estimation of phenols, flavonoids and tannins). The correlation, regression and one way ANOVA analysis also statistically support the results. A positive correlation was found in between phyto- constituent and radical scavenging activity. The results obtained from this investigation revealed out that these are equally competent and could be recommended as dietary supplements or as nutraceuticals.

Topical issues of an applied vaping research
Authors: Davletshina L. A. , Karmanov M. V.
Published: September 2022

The authors study the history and origins of vaping as a mass social phenomenon. Currently, users of electronic cigarettes and similar devices are divided into two segments: traditional smokers who switched to electronic cigarettes or combining them and new smokers who chose electronic cigarettes because of fashion, communication, entertainment, etc. It turns out that vaping is a social phenomenon that follows not only from one the desire to find an alternative to smoking. A large-scale discussion regarding vaping has unfolded in special scientific publications and in the media. It can be considered not only as a youth culture direction or trend, but also as a new unfavorable factor that strikes at the health of younger generations. All the existing deep and large-scale discrepancies in the content, place and role of vaping in modern society are certainly theoretical, and partly rhetorical. Without reinforcement by quantitative characteristics of its most diverse aspects, it is impossible to give a practical assessment of such a specific phenomenon. Applied vaping research is based on a set of exact indicators combined into a single and logically sound system that allows you to get a comprehensive idea of the object of cognition. The article presents the content of three existing independent sections of the system of vaping statistics indicators. The authors propose indicators that reveal the section of indicators of the effects of vaping. The possibilities of applied analysis of the consequences of the spread of electronic cigarettes in modern society are assessed.

Authors: Denisova A. I.
Published: September 2022

The article shows the need to develop methods for quantifying the associated internal risks of planning and implementing government programs. The author demonstrates an approach to assessing the risk magnitude of programs by analyzing the ranges of stability of the program’s action plan parameters. A test case based on retrospective data from the state program of the Arkhangelsk region shows the applicability and adequacy of this approach. As part of the test case, the researcher showed the possibility of adapting the program’s action plan due to the influence of associated risks, assessing the magnitude of the program’s associated risks as indicators of the most problematic areas of implementation, and comparing the results of calculations with actual risks. The software implementation of the algorithms for the formation and evaluation of the program plan was carried out in the form of software developed by the author in the Python.

Direct photolysis of 4-tert-alkyl-1,4-dihydropyridines under blue-light irradiation for the generation of tertiary alkyl radicals
Authors: Gallage Prasadi , Pitre Spencer
Published: September 2022

Herein, we disclose a direct photolysis approach for the generation of tertiary alkyl radicals from 4-tert-alkyl-1,4-dihydropyridines (DHPs) under blue LED irradiation, as exemplified in a photochemical Giese reaction. Radical generation occurs under mild conditions, does not require the use of exogenous photocatalysts or oxidants, and the Giese reaction is compatible with a range of 4-tert-alkyl-DHPs and Michael acceptors (23 examples, up to 86% yield). Mechanistic investigations reveal that the presence of base is crucial for radical generation.
Charge-transfer-to-solvent states provide a sensitive spectroscopic tool to probe local structure of water around solvated anions
Authors: Sarangi Ronit , Krylov Anna I.
Published: September 2022

This computational study characterizes charge-transfer-to-solvent (CTTS) states of aqueous thiocyanate anion using equation-of-motion coupled-cluster methods combined with electrostatic embedding quantum mechanics/molecular mechanics (QM/MM) scheme. Equilibrium sampling was carried out using classical molecular dynamics (MD) with standard force-fields and QM/MM ab initio molecular dynamics (AIMD) using DFT. The two calculations yield significantly different local structure around solvated SCN−. Because of the diffuse character of CTTS states, they are very sensitive to the local structure of solvent around the solute and its dynamic fluctuations. Owing to this sensitivity, the spectra computed using MD and AIMD based snapshots differ considerably. This sensitivity suggests that the spectroscopy exploiting CTTS transitions can provide an experimental handle for assessing the quality of force-fields and density functionals.
Bio-inspired heterogeneous Fe4S4 single-cluster catalyst for enhanced electrochemical CO2 reduction to CH4
Authors: Xu Hengyue , Ma Lan
Published: September 2022

Electrochemical conversion of carbon dioxide promises next-level paradigm shifts in sustainability. Applications will include breakthrough solutions to global crisis threatening our civilization, including energy, food, and climate change. Here, inspired by CO dehydrogenase II from Carboxyothermus hydrogenoformans, we designed a heterogeneous Fe4S4 single-cluster catalyst Ni100-Fe4S4, achieving high performance CO2 electroreduction. Combined with the experimental data and theoretical calculation, Ni100-Fe4S4 and CO dehydrogenase have highly similar catalytic geometric centers and CO2 binding modes. By exploring the origin of catalytic activity of this biomimetic structure, we found the activation of CO2 by Ni100-Fe4S4 theoretically exceeds that of natural CO dehydrogenase. Density functional theory calculations reveal that the dehydrogenase enzyme-liked Fe-Ni active site as an electron enrichment 'electro-bridge', activating CO2 molecules efficiently and stabilizing various intermediates in multistep elementary reactions to produce CH4 in a low overpotential (0.13eV) selectively. The calculated electroreduction pathway can completely consistent with the nickel-based catalytic materials reported in the current experiments. This work demonstrates that it is efficient and feasible to design biomimetic high-performance catalytic materials by using blueprints provide by nature. Combining ideas from modern catalyst design with bio-inspired strategies will lead our catalysts beyond its current limitations.

The merger of open-shell and closed-shell organometallic chemistry steps has enabled multiple effective cross-coupling pathways. Here we report a visible-light promoted photoredox-cobalt catalyzed Minisci reaction of N-heteroarenes under mild and sustainable conditions, employing various boronic acids and derivatives as alkyl radical precursors. This study demonstrates the prominent ability of the Co co-catalyst to promote the oxidation step of the photocatalytic cycle following a reductive quenching pathway, thus avoiding the use of stoichiometric (inorganic) oxidants. This feature enables the straightforward application of photo-flow conditions, particularly attractive for an easy scale-up and to enhance the efficiency of the reaction (throughput: 0.78 mmol/h in flow vs 0.02 mmol/h in batch) Furthermore, the process is predominantly selective towards the C2-alkylation of quinolines, and a mechanistic rationale has been provided with both experimental and DFT calculation support. The developed protocol demonstrates broad applicability for the alkylation of different N-heteroarenes under suitable homogeneous conditions for a flow-compatible Minisci reaction.
Conjugation-Modulated Excitonic Coupling Brightens Multiple Triplet Excited States

Published: September 2022

The design and regulation of multiple room-temperature phosphorescence (RTP) processes are formidably challenging due to the restrictions imposed by Kasha’s rule. Here we report a general design principle for materials that show multiple RTP processes, which is informed by our study of four compounds where there is modulation of the linker hybridization between donor (D) and acceptor (A) groups. Theoretical modeling and photophysical experiments demonstrate that multiple RTP processes can be achieved in sp3 C-linked D-A compounds due to the arrest of intramolecular electronic communication between the T2 and T1 states. However, for the sp2 C-linked D-A counterparts, only RTP from T1 is observed because of enhanced excitonic coupling between the T2 and T1 states. Single-crystal and reduced density gradient analyses reveal the influence of molecular packing on the coincident phosphorescence processes and the origin of the observed aggregate phosphorescence. These findings provide insight into high-lying triplet excited state dynamics and into a fundamental design principle for designing compounds that show multiple RTP.
