Relationship between Successful Cervical Carotid Stent Expansion and Low Levels of Serum Vitamin D
Authors: Kim Han Jun , Han Jung Hoon , Oh Kyungmi , Kim Chi Kyung
Published: June 2022

Background: Serum vitamin D levels affect atherosclerosis development via diverse molecular mechanisms. The lesion characteristics of carotid stenosis affect the success of stent expansion. By comparing the pre-and post-stenting stenosis degrees, our study evaluated whether serum vitamin D levels are associated with the expansion rate of carotid stenting.Methods: Forty-six cases who underwent elective cervical carotid artery stenting were analyzed. Patients were classified into two groups according to serum total 25-hydroxy vitamin D (25[OH]D) levels; <15.1 and ≥15.1 ng/mL. The degree of stenosis before and after stent insertion was calculated using the North American Symptomatic Carotid Endarterectomy Trial (NASCET) method. The stent expansion rate was calculated as follows: (1-[post-stent stenosis degree/pre-stent stenosis degree])×100 (%). To identify the independent factors for successful stent expansion, multivariable logistic regression analysis was conducted.Results: Among the 46 patients, 25 (54.3%) had low serum 25(OH)D levels. The successful stent expansion rate was significantly higher in the low 25(OH)D level group (48.0% vs. 19.0%, respectively; p=0.04). In multivariable analysis, after adjusting for possible covariates, a low serum 25(OH)D level was independently associated with successful stent expansion (adjusted odds ratio, 6.47; 95% confidence interval, 1.11-37.80).Conclusion: Low serum vitamin D levels were independently associated with successful carotid stent expansion. This study presents a new perception of biomarkers that should be considered for satisfactory carotid artery stenting.

Published: June 2022

We report a case of severe, non-migraine headache accompanied by multifocal cerebral artery stenosis in a 41-year-old man with antiphospholipid syndrome (APS). He visited the emergency department with a headache that had occurred 2 days prior to presentation. He was administered low-dose aspirin (100 mg) daily after being diagnosed with antiphospholipid syndrome. Magnetic resonance angiography revealed severe multifocal cerebral artery stenosis. We assumed that multiple stenoses of the cerebral blood vessels were caused by APS; hence, we initiated pulse intravenous methylprednisolone therapy. Oral anticoagulation with warfarin was continued. After treatment, the symptoms and stenosis of the cerebral arteries gradually improved. Awareness of central nervous system vasculitis (with non-migraine headaches) caused by APS should be created among clinicians.

Published: June 2022

Diabetes mellitus is a disease caused by high blood glucose levels, and one way to overcome it is by inhibiting the digestive enzyme, α-amylase. The henna plant (Lawsonia inermis L.) has been shown to show potential as an antidiabetic through inhibition of the enzyme digestive, but its molecular mechanism has not been revealed. Therefore, the aim of this study was to reveal the α-amylase enzyme inhibitory activity of phenolic compounds in the henna plant by molecular docking and molecular dynamics. The protein used was a high-resolution α-amylase crystallographic protein with the code PDB: 1XD0, and the ligands used were 20 phenolic compounds that were known to be contained in the henna plant. The phenolic compounds were docking, then a molecular dynamic simulation was carried out, and then compared with acarbose. Molecular docking analysis shows 3 compounds with the best binding energies, e.g. Acacetin-7-o-glucoside, laxanthone-2, and laxanthone-3. Furthermore, tracing the stability of the three compounds using a molecular dynamics simulation based on the parameters of SASA, Rg, PCA, and MM-PBSA binding free energy, obtained good stability and is close to acarbose as reference ligand.

Published: June 2022

Caffeine is a natural alkaloid used as a key ingredient in craft and industrially produced beverages. The caffeine concentration in water bodies worldwide is increasing to the point of being classified as an emerging contaminant with potentially harmful effects on aquatic ecosystems. Given the importance of both, coffee and carbon production in Colombia, activated carbons prepared from local mineral coals have been considered a cost-effective alternative for the treatment of wastewater from coffee plantations. In this study, activated carbons from the Colombian regions of Cundinamarca and Santander were evaluated as matrices for caffeine adsorption in an aqueous solution. The prepared activated carbons were characterized and subjected to adsorption tests and kinetic studies. The caffeine concentration (adsorbate) and the activated carbon (adsorbent) to liquid ratio were considered as the experimental factors in the evaluation of removal capacity. The results showed that the mineral coal from the Cundinamarca region has better physicochemical (low ash and volatile matter contents and high iodine number) and better adsorption capacity, reaching specific caffeine retention of 882.1 mg/g. The adsorption process corresponds with Freundlich’s adsorption model suggesting heterogeneous adsorption, while pseudo-second-order kinetics indicated the dominance of a chemical adsorption mechanism.

Published: June 2022

Fused aromatic systems with homo and heterodimer stacked conformation shows effective π-π interactions in the gas phase. Here, we have investigated the π-π stacking interaction of some fused aromatic rings (viz. α-naphthol, βnaphthol, naphthalene etc.) and tried to make their stacked dimers to analyze the actual stacking interaction for different conformations. All these stacked models show strong stacking interaction between the homo dimer of such fused ring systems. It is also an important aspect to analyze the strength of stacking interaction energy with a thin fused dimer of aryl systems. All kinds of interaction energies including the electron-electron correlation energy can be calculated properly by using the appropriate DFT method. Herein, the stacking interaction energy of the stacked systems of naphthalene, α-naphthol, and β-naphthol has been accounted by using the M062X method.

Authors: Manan Nor Ashikin Ab , Azizan Noraziah
Published: June 2022

The study was conducted to address the problem of English language speaking anxiety among adult ESL learners by introducing vlogging as one of the learning activities and as an assessment of speaking skills. The main objective of this action research was to establish whether vlogging assignments could assist in alleviating speaking anxiety among adult learners and in determining whether the students' vlogs posted in the class's Facebook group could be used as part of the course's speaking assessment to replace face-to-face presentation. A qualitative research design was adopted in this study. The study employed purposeful sampling, and the participants chosen came from an intact group of thirty adult learners who enrolled in a distance learning programme at a public university in Malaysia. The study was conducted in the students’ ‘English for Communication’ class over a study period of fourteen weeks. The data was collected at the end of the study period through focused group interviews and analysed using the thematic analysis method, and presented descriptively. It was found that vlogging is effective in increasing the students’ English talk time outside class which consequently contributes to increasing their self-confidence and alleviating speaking anxiety. Thus, it can be concluded that vlogging is effective in lessening language speaking anxiety among the participants and can effectively be used as an assessment tool to reduce test-taking anxiety. Facebook group is also found to be a suitable platform for group interactions as it provides a non-threatening learning environment for the learners. The findings of the study have potential implications for English language teaching among adult learners.

Published: June 2022

Using Critical Discourse Analysis as an analysis tool, this study explores gender representation in the national EFL textbook “Bright: An English” for Eighth Grade Junior High School students, a book utilized in Al-Ikhlas Lambuya Junior High School’s learning and teaching process. Fairclough's three-dimensional framework was used to examine the data in this study. The study aims to see how gender roles are communicated and how gender equity is reflected in the textbook. To uncover the power imbalance or disparity between males and females, characteristics such as male and female visual representation, male and female characters, male and female social, domestic duties, male and female semantic roles, and activities were investigated. The research revealed a gender bias in favour of men in particular functions and activities, such as becoming an 'athlete,' engaging in social events, and participating in sports. On the other hand, female dominance is evident in that female students outnumber male students significantly. Nevertheless, the study discovered some equality in terms of pictorial representation, some activities, and roles. Although conventional roles and behaviours are associated with female and male genders in this book, all genders are equally portrayed in terms of social position, power, and domination. Furthermore, no ideology such as anti-feminism or masculinity is discussed in this text.

Published: June 2022

Breakthrough RESEARCH has conducted a study to monitor the family planning (FP) quality assurance branding campaign in Côte d’Ivoire called Confiance Totale. Implemented by Breakthrough ACTION, Confiance Totale (French for Complete Trust) aims to increase demand for and use of quality FP services in Francophone West Africa. The promotional campaign, developed in early 2020, theorizes that promotion of safe and effective FP within a supportive social context will lead to an increase in demand for FP services, following the theory that mass media influence not only individual FP skills and knowledge but also environmental supports, constraints, and ideational factors in the cognitive, social, and emotional domains. Confiance Totale addressed these determinants by providing guidance to couples to increase communication about FP and by addressing key concerns, encouraging audiences to have confidence in the safety and effectiveness of FP methods and the need for FP services to offer welcoming, competent providers.The monitoring study, conducted by Breakthrough RESEARCH, sought to determine (1) the level of unprompted recall of the Confiance Totale campaign among target beneficiaries and (2) if recall of the campaign was associated with higher levels of perceptions of FP safety, FP-related social norms, self-efficacy, spousal communication about FP, intention to talk to a partner about FP, intention to seek FP information at a health facility, intention to use FP, and current use of FP methods.

Feeling disorder a group of clinical features characterized by reduced or lost emotional control and self-control. Affective disorders can be depression, manic or a mixture of both (bipolar). Someone who has mood disorders needs treatment as early as possible through early detection and an accurate assessment is carried out in consultation with a psychologist. So a system is needed that can detect the possible disturbance of the mood. Expert systems are part of artificial intelligence that mimics the slow pace of an expert. Bayes' Theorem is a way of knowing conditional probabilities. Conditional probability is the probability of an event occurring, given that it has some relationship with one or more other events. The probability value of symptoms and disease is obtained based on the experience of an expert. This expert system can produce a process of diagnosing mood disorders with some data about mood disorders in the form of symptom data, disease data and its probability value. The accuracy rate is 100% using 10 test data. An expert system for diagnosing mood disorders which is designed to be an Android-based application of JavaScript and PHP as a programming language, Cordova as a framework for creating mobile applications, PHP 7.2.1 as a web server, MySQL 5.0.21 as a database.

The vocational Forecasting process is an important thing for the Forecasting process to determine new students to obtain data and information on the number of prospective new students who will register. Darussalam Islamic Vocational School does not yet have a Forecasting application so predicting the number of students is still conventional which causes school to be unable to plan for future needs. Therefore the Forecasting applications are needed. The purpose of this study is to produce an application to make it easier for schools to predict the number of new students in the future. This research method uses the Single Exponential Smoothing method, while the development method uses the Waterfall. method. In this study, Testing. will be carried out using a Black-Box involving users, namely the principal and of school study program. The test consists of 4 aspects of Testing, namely the login process, the import process, the process of adding data, the process of Forecasting the number of new students. With the Forecasting application. the number of new students that have been MAD can predict the number of students who will register in the following year based on previous data.

To increase the allocation of water in the river basin (WS) of southern Lombok, the potential for irrigation areas (AI) has spread widely, since the 1980s, efforts have been made to transfer water from wet river basins to dry watersheds. The transfer is through the Babak-Renggung-Rutus High Level Diversion (HLD) channel (18 km) and the Jangkok-Babak-Jurang Sate channel (43 km), as well as 22 other channeling channels in / across the watershed (87 km). Until now, 12 watersheds are connected, namely: Meninting, Jangkok, Remening, Babak, Dodokan, Renggung, Pare, Rere, Palung, Moyot, Aikampat and Starfruit. The number of main structures for taking water (headwork or HW) in the watersheds include 3 dams (BD), 77 reservoirs (E), 355 dams (B), and 55 diversions in the Jangkok-Babak-Jurang Sate canal. A total of 487 HWs were intended to irrigate 98,878 ha of irrigated land in 432 Irrigation Areas (DI) and a little to supply raw water of 404 l / sec. In addition, there are 2442 l / sec raw water withdrawals directly from 42 points of springs which are spread in the watershed: Jangkok, Babak, Aikampat, Meninting Midang, Kelongkong Remening, Renggung, Rung and Starfruit. Analysis of reservoir operational performance using the Hashimoto method yields a coefficient of Reliability (R) = 100%, Resiliency (R) = 100%, and Vulnerability (V) = 0%. So based on this RRV value the reservoir operational performance is categorized as maximum sustainable

Indonesia is the confluence of three of the world's major plates, therefore a lot of plate activity occurs so that earthquake intensity often occurs. The earthquake resulted in many casualties, this is because many building structures do not meet the requirements of earthquake-resistant buildings. The structure of mosque buildings in Lombok has many towering mosque towers. Many mosque buildings in Lombok do not apply the earthquake-resistant building principle, namely strong column weak beam, so that the average mosque building collapses is the soft story type. The research method used to optimize the dimensions of the columnar beam in this study there are two methods, namely optimization using SAP 2000 and then optimization using Artificial Neural Network (ANN) modeling. The empirical equations obtained are three equations, namely the equation of a beam, a square column and a circle column. The percentage of error that occurs in the use of the empirical formula is 0.88%, so that the equation can be used to perform dimensional prediction calculations with different variations.
