Schistosomiasis or bilharziasis is a parasitic disease caused by flatworms or plathelminthes: bilharzias or schistosomes that live in the venous vascular system. This disease is a major public health problem in countries located in the tropics and subtropics. The general objective of this work was to contribute to the eradication of schistosomiasis in Côte d'Ivoire by highlighting the endogenous knowledge of the Attie people on the medicinal plants used for the treatment of schistosomiasis in the Health District of Adzope. An ethnobotanical survey was conducted among practitioners of traditional medicine (TMP), using a semi-structured interview associated with the show-and-tell technique. A total of 33 medicinal species have been listed. They are divided into 31 genus and 21 botanical families with a predominance of Annonaceae, Asteraceae, Euphorbiaceae and Fabaceae, each with three species. The most cited species are Combretum paniculatum (CF = 14.79%) and Mareya micrantha (CF = 10.56%). The leaves are the most used organs; the decoction is the main mode of preparation of the recipes which are generally administered orally. The results of this study constitute a valuable database for further research in pharmacology and phytochemistry.

Islamic stock market has experienced massive growth globally, including in Indonesia. This study aims to investigate the predicting factors of the Indonesian Islamic stock market that presents by the stock price of the Jakarta Islamic Index (JII). Adopted the Augmented Distributed Lag (ARDL) approach, this study uses monthly data from January 2007 to February 2020. This study uses five macroeconomic variables, namely consumer price index, exchange rate, crude oil price, world gold price, and Dow Jones Islamic Index (DJIM), to determine the JII's stock price. As a result, the JII's price volatility is significantly driven by the macroeconomic variables simultaneously. Importantly, this study reports that world gold price and DJIM return to become the most crucial factors influencing the ' 'JII's stock price volatility in short and long-run investment periods. This study has passed robustness checks by conducting three out of sample periods, namely 25%, 50%, and 75% out of sample. The 75% and 50% out of sample data revealed an identical result. Thus, this study suggests that the investor evaluates the crude oil price and world gold price fluctuation to predict the price of JII. This study offers practical implications for policymakers and practitioners and recommendations for future research.

Published: December 2022

This research aims to show the effect of the value of the halal label and celebrity endorser on purchasing decisions for halal cosmetic products with religiosity as a moderating variable. The method uses descriptive quantitative by analyzing the responses to questionnaires distributed to 228 respondents in Indonesia. Based on previous research, four hypotheses were built, and the collected data were processed using a path analysis tool through the Smart PLS 3.3.3 application. The results showed that the halal label variable and celebrity endorser significantly affected purchasing decisions for halal cosmetic products, with religiosity as a moderating variable. Meanwhile, the religiosity variable does not moderate the effect of the halal label and celebrity endorser on the decision to purchase halal cosmetic products. This finding confirms that religiosity has not sufficiently strengthened the influence of the halal label and celebrity endorser on the decision to purchase halal cosmetic products. In order to increase knowledge of Muslim halal in purchasing decisions for halal cosmetic products, the role of halal guarantee institutions and cosmetic manufacturers is needed in optimizing halal certification both from the content and production process. Business actors must increase awareness of the halalness of a product that can convince and encourage Muslim consumers, especially the millennial generation, to make decisions to purchase halal cosmetic products in Indonesia. This study is the first to examine the halal label and celebrity endorser on the decision to purchase halal cosmetic products with religiosity as a moderating variable and reveal its strength and weakness.

The rapid spread of information and infodemic might result in public confusion and hinder the handling of the COVID-19 pandemic. Public comprehension of COVID-19 as part of health literacy is an important determinant to filter hoaxes from facts. Therefore, a scoring card called the Karlivid (the COVID-19 literacy and public vaccination scorecard) was developed to evaluate the individual’s comprehension level of COVID-19. A pilot study was conducted with this scoring card. The participants were recruited via consecutive random sampling by using emails from the researcher’s contact list (n=92). A total of 78.3% of the respondents were considered to have an adequate comprehension level. Approximately 77% of all respondents agreed that this card could help them know their comprehension level, 81.5% agreed that this card could improve their comprehension, 81.5% agreed that the items in this card could help them screen facts from hoaxes, and 81.5% agreed that the language used was easily understood by the laypersons. Therefore, the Karlivid is a valid and reliable scorecard that can be used to evaluate public comprehension of COVID-19. Most of the respondents also had a good level of comprehension of this assigned topic

Published: December 2022

Increased definite power, reduced cost, and dynamic construction are the important features required by electric motors for various applications. One such motor accommodating all the requisites mentioned above is Switched reluctance. Applications pertaining to small, commercial, and EV find Switched reluctance machine as a developing competitor to the conventional induction and permanent magnet motors. Though SRMS contribute a considerable number of advantages over induction motors and permanent magnet motors, the primary disadvantages pertaining to SRMs are the torque ripple, especially at high-speed operation, and the resulting acoustic noise. These disadvantages may not always be detrimental to the systems in entirely all cases, but depending on the application to be employed, torque ripple and acoustic noise form are detrimental to the system. This paper reviews the technology status and recent trends in the minimization of torque ripples switched reluctance machines.
Never Ending Story? Biothermodynamic Properties of Biosynthesis and Binding of Omicron BQ.1, BQ.1.1, XBB and XBB.1 variants of SARS-CoV-2
Authors: Popovic Marko
Published: December 2022

RNA viruses exhibit a great tendency to mutate. Starting from 2019, the wild type that was labeled Hu-1 has during the last 3 years evolved to produce several dozen new variants, as a consequence of mutations. Mutations cause changes in empirical formulas of new virus strains, which lead to change in thermodynamic properties of biosynthesis and binding. These changes cause changes in the rate of reactions of binding of virus antigen to the host cell receptor and the rate of virus multiplication in the host cell. Changes in thermodynamic and kinetic parameters lead to changes in biological parameters of infectivity and pathogenicity. SARS-CoV-2 has starting from in 2019, until today, evolved towards increase in infectivity and maintaining constant pathogenicity, or for some variants a slight decrease in pathogenicity. In the case of Omicron BQ.1, BQ.1.1, XBB and XBB.1 variants pathogenicity is identical as in the Omicron BA.2.75 variant. On the other hand, infectivity of the Omicron BQ.1, BQ.1.1, XBB and XBB.1 variants is greater than those of previous variants. This will most likely result in the phenomenon of asymmetric coinfection, that is circulation of several variants in the population, some being dominant.

Published: December 2022

A robot-based laser 3D hardening method is proposed as a finishing operation to increase the wear resistance of the metal end-products. The laser hardening process of the surface layer of the products by changing its structure is one of the most effective methods of selective surface hardening. Thermal hardening of metals and alloys by laser radiation is based on local heating of a surface area under the influence of radiation and subsequent cooling of this surface area at a supercritical speed due to heat removal into the inner layers of the metal. The used robot-based laser 3D system (FANUC industrial robot and SCANLAB scanning optics) allows processing the surfaces of any complexity and geometry, including the shafts of the gear mechanism of the seed drill. It was found that the development and improvement of the technological process of manufacturing steel shafts of the gearbox of the seed drill is an urgent technological problem due to the rapid retirement of the shaft, which leads to the expenditure of time and money for its replacement. The most heavily loaded sections of the shaft were pre-estimated using the SolidWorks Simulation software package. A high-power TruDisk 8002 solid-state disk laser with a maximum laser power of 8 kW and a wavelength of laser radiation of 1030 nm is used for high-quality laser surface treatment of the AISI 1066 steel shaft of the gear mechanism. The laser surface heat treatment was carried out using a constant power strategy (continuous mode), varying the laser power in the range of 1.35–2.25 kW. Based on the Fe-Mn two-component state diagram, the critical points of the temperature of complete austenization of the studied steel were previously predicted taking into account the chemical composition of the material. Additionally, the energy density values of the laser beam with a diameter of 1 mm on the working surface was estimated. The results showed that the surface hardness  of  the  shaft  was  about  2.5  times  higher  compared  to  the  untreated  surface.  The  working  ranges  of  laser  heat treatment  parameters  of  the  gearbox  shaft  were  established  to  increase  the  hardening  intensity  (100–150%)  of  the responsible areas.

At approximately 7:00 p.m. on January 3, 2022, a bedding landslide (referred to as the Jinhaihu landslide in this paper) occurred in the Jinhaihu District of Bijie city, Guizhou Province, China, resulting in the death of 14 laborers. The catastrophic landslides induced by the geological conditions in the study area are incomprehensible and deserve an in-depth study of their genetic mechanisms. In this paper, a detailed field investigation was conducted on the Jinhaihu landslide, and the geological background of the landslide area and the characteristics of the landslide were well revealed. The slide zone and rock samples of the landslide site were obtained for physical and mechanical tests to further establish a coupled PFC/FLAC2D model of the landslide area and analyze the genetic mechanism of the Jinhaihu landslide using numerical simulation. The results indicate that the landslide area has been disturbed by long-term engineering, and a large amount of excavation at the foot of the slope has reduced the resistance of the landslide to slide downward, increased the damage to the slope, and provided space for the landslide to move. However, the excavation did not immediately initiate the landslide at the toe, and the claystone containing a large number of illite clay minerals (56.5%) gradually weakened with the infiltration of rainfall before the slope finally failed. The numerical simulation indicated that the excavation at the toe of the slope caused cracks at the crown, the softening of the claystone caused the sliding mass to be divided into blocks by the cracks, and then the sliding mass slid downward along the weak interlayer. First, the sliding mass toppled down and disintegrated at the front edge, and the rear of the sliding mass was tensile-fractured and failed. The movement of the rock blocks on the slide bed has the character of translation with almost no rotation. The evolution process of landslides is divided into four stages: the initial stage, fracture generation stage, softening stage and overall failure stage. The research results of this paper provide a reference for the risk evaluation and disaster prevention of the same category of landslides.

Published: December 2022

Background
Increasingly, the shared risk factors and pathological processes of atherosclerosis and abdominal aortic aneurysm (AAA) are being recognized. However, the exact mechanism underlying the shared pathogenesis of atherosclerosis and AAA formation remains unclear.
Methods
The aim of our study was to identify the hub genes involved in the pathogenesis of atherosclerosis and AAA. Our analysis was based on two gene expression profiles for atherosclerosis (GSE28829) and AAA (GSE7084), downloaded from the Gene Expression Omnibus (GEO) database. Common differential genes were identified and an enrichment analysis of differential genes was conducted, with construction of protein-protein interaction networks, and identification of common hub genes and predicted transcription factors.
Results
The analysis identified 133 differentially expressed genes (116 upregulated and 17 downregulated), with the enrichment analysis identifying a potential important role of integrins and chemokines in the common immune and inflammatory responses of atherosclerosis and AAA. Regulation of the complement and coagulation cascades and regulation of the actin cytoskeleton were associated with both diseases, with 10 important hub genes identified: TYROBP, PTPRC, ITGB2, ITGAM, PLEK, CTSS, LY86, ITGAX, CCL4, and FCER1G.
Conclusions
Findings identified a common pathogenetic pathway between atherosclerosis and AAA, with integrin-related genes playing a significant role in both diseases. The common pathways and hub genes identified provide new insights into the shared mechanisms of these two diseases and can contribute to identifying new therapeutic targets and predicting the therapeutic effect of biological agents.

Purpose: To investigate the effects of managing retinal diseases by OCT exam alone due to COVID-19 pandemic on the treatment course of nAMD, DME and RVO patients, and compare it with real-life data.
Methods: A comparison between patients whose treatment was based on OCT alone during COVID-19 lockdown limitations and patients who visited the retina unit one year before.Recorded parameters included demographic data, visual acuity, OCT characteristics, number of anti VEGF injections to each eye before the COVID-19 visit, referral for intravitreal injections , number of injections and anti-VEGF drugs administered.
Results: A total of 165 eyes of 133 patients were included in the study group, and189 eyes of 145 patients in the control group. Both groups had similar baseline characteristics. Patients in the study group were referred to more anti VEGF injections than the control group (71.5%of patients vs 41.8 ,p<0.0001) Final visual acuity was better in the study group, but although this difference achieved statistical significance (p=0.037), it was a small change not likely to be clinically significant. The differences in CMT and volume changes were also not significant.
Conclusion: Treating patients with nAMD, CME due to RVO or DME with anti VEGF injections according to OCT imaging alone did not harm patients, and achieved satisfactory results. Adoption of this treatment regimen can be considered also for patients live in remote areas.

A big infectious wave overwhelmingly spread from February 2022 in South Korea after the COVID-19 outbreak was managed. Therefore, we analysed electroencephalogram (EEG) findings and serologic inflammatory markers in pediatric patients with COVID-19 by retrospectively reviewing medical records of 41 patients who visited Gyeongsang National University Changwon Hospital from March to May 2022 and were diagnosed with COVID-19; all serologic tests were performed within 24 hours after presenting with fever or seizure. The median patient age and average number of hospitalisation days were 3.6 (0.08–14.00) years and 3.71 (1.0–7.0) days, respectively. Interleukin-6 (IL-6) were elevated above the normal range in all patients (median value, 43.18 [7.0–190.0] pg/ml) and were higher among patients with seizures. Among 41 patients, 17 (41.5%) with a mean age of 5.4 years had higher complaints of seizures. Three patients had prolonged seizures for > 30 minutes and received intravenous lorazepam injections and eight had a complex type of febrile convulsion. Nine patients underwent EEG, and five showed abnormal findings in the initial EEG. In the linear regression model, serum IL-6 and blood lymphocyte counts were correlated with prolonged seizure duration. These findings underscore that several immune cascade-related serologic markers were elevated in children with COVID-19-related febrile seizures. We may assume that COVID-19 presents similarities and differences in the mechanisms that provoke seizures and fever in children.

Emerging evidence indicates that coffee consumption significantly reduces the risk for developing Parkinson disease (PD). We aimed to investigate the role of chronic coffee consumption in nigrostriatal dopaminergic neurodegeneration using 123I-FP-CIT single photon emission computed tomography. Overall, 138 PD patients and 75 healthy controls (HC) were enrolled from the Parkinson’s Progression Markers Initiative cohort. Demographic, clinical and striatal dopamine transporter (DAT) characteristics were compared across subgroups, including current, ever and never coffee consumers in PD patients and HC, respectively. Furthermore, we included the factors that may have influenced the loss of nigrostriatal dopaminergic neurons in multiple linear regression analyses to identify significant contributing factors to striatal DAT binding in each striatal region. In PD patients, current consumers had significantly lower DAT binding in the bilateral caudate than ever/never consumers. In HC, current consumers had significantly lower DAT binding in the bilateral caudate and right putamen than ever/never consumers. Cups per day were negatively correlated with the left caudate DAT binding in current consumers of PD patients. In addition, multiple linear regression analyses showed current coffee consumption remained as an independent predictor of a decrease in striatal DAT binding. Striatal DAT downregulation caused by chronic effects of caffeine may provide evidence for the favorable implication of caffeine to PD pathologies. Furthermore, our study firstly suggests that the chronic effects of caffeine on striatal DAT may fade and disappear after quitting coffee.

Published: December 2022

Objectives
To describe the characteristics of high-incidence comorbidity combinations of pediatric ventricular septal defect (VSD) among inpatients in Shanghai, China.
Methods
In total, 5,994 inpatient pediatric VSD cases with ICD-10-based diagnoses were retrospectively studied. The top combinations and influencing factors associated with comorbidities were analyzed by the chi-squared test.
Results
Patients were predominantly aged 0–1 year (50.47%), had one admission (90.89%), and had surgery once (37.14%) or twice (38.71%). Major comorbidities were cardiovascular and respiratory. VSD + atrial septal defect (ASD) (14.58%), VSD + ASD + secondary pulmonary hypertension (PH) (4.75%) and VSD + ASD + patent ductus arteriosus (PDA) + secondary PH (0.67%) affected the most patients in each comorbidity group. Other top comorbidity groups included VSD + patent foramen ovale (PFO) (4.05%), VSD + ASD + primary PH (2.92%) and VSD + ASD + secondary PH + pneumonia (0.53%). Characteristics of the combinations were examined, and age, with the highest prevalence seen in those aged between 0 and 1 year, number of operations (p < 0.001 in each comorbidity group), length of stay (LOS) (p = 0.001 in the 2 comorbidities group; p = 0.002 in the 4 comorbidities group) and hospitalization cost (p < 0.001 in the 2 comorbidities group; p = 0.011 in the 3 comorbidities group) differed significantly.
Conclusions
VSD + ASD, VSD + ASD + PH, and VSD + ASD + PDA + secondary PH occurred most frequently in each comorbidity group. Age, number of operations, LOS and hospitalization cost were significant among these combinations, which emphasizes the importance of a better understanding, diagnosis and treatment for complex comorbidities of VSD in young populations to improve clinical outcomes and provide guidance for relevant policies on resource utilization.
Indirect Taxes, Inflation and Inequality in Turkey
Authors: Gemicioğlu Selçuk , Akkoç Uğur , Kızılırmak Burça
Published: December 2022

One way inflation affects inequality is through its varying impact on the purchasing power of different households. Indirect taxes, which affect commodity price levels, are another effective factor influencing inequality. Turkey is a highly unequal country with a long history of high inflation. Moreover, indirect taxes have been used frequently as a policy tool in the last decades. This study applies the commonly used method in the literature to analyse distributional consequences of household level inflation rates, and extends it to analyse the role of indirect tax changes in this relationship. The analysis is carried out using both household-level data and artificial panel data created to apply the Shapley and Owen decomposition methods. The findings indicate that while nominal consumption during the 2003–2019 period became more equal, real consumption inequality increased as a result of price changes during that time. Another striking finding is that changes in indirect taxes account for 31–57% of the unequalizing effect of price changes, depending on the method used.
