OBJECTIVE: Cardiovascular disease is the main cause of mortality in patients with chronic kidney disease stage 5 on dialysis (CKD-5D). High sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-a (TNF-a), and neutrophil-lymphocyte ratio (NLR) are several inflammatory parameters associated with high cardiovascular events in CKD-5D. The main aim of this study was to evaluate the effect of reduced L-glutathione supplementation on serum hs-CRP, TNF-a, and NLR in patients with CKD-5D. PATIENTS AND METHODS: This study is a quasi-experimental research with one group pretest-posttest design. Subjects included were patients with CKD-5D who routinely underwent hemodialysis therapy two times a week in Hasan Sadikin General Hospital. Serum hs-CRP, TNF-a, and NLR levels were obtained before and after the intervention of reduced L-glutathione supplementation dosing of one thousand milligrams a day for four weeks. Statistical analysis was then conducted using the Wilcoxon test. RESULTS: There were 26 hemodialysis patients included in the study, with a median age of 43 years and a male predominance. There was a significant decrease in serum TNF-a level after reduced L-glutathione supplementation for 4 weeks, 5.40 (-10.80-0.00) pg/mL, p = 0.002. However, there was no statistically significant decrease in either serum hs-CRP level, 0.40 (-0.70-0.80) mg/L (p = 0.656), or NLR with a difference of 0.55 (0.30-1.00) p = 0.055. CONCLUSIONS: Exogenous oral reduced glutathione supplementation for four weeks significantly reduced TNF-a level, but no significant decrease in hs-CRP level and NLR in patients with CKD-5D.

A novel mathematical modeling approach for the Triple-Diode Model (TDM) and its parameter estimation is introduced in this paper. For the first time in the literature, this paper presents two analytical solutions for calculating the current in TDM solar cells using the Lambert W function. Additionally, a new metaheuristic algorithm, the Adaptive Evaporation Rate Water Cycle Algorithm (Adaptive ERWCA), is proposed for estimating TDM solar cell parameters. The proposed algorithm is tested using both the new analytical solutions and a well-known iterative approach for the current-voltage characteristics of the TDM solar cells model. Extensive testing is conducted on three well-known solar cells/modules and a panel under various weather conditions. The results demonstrate that the proposed analytical expressions for the current-voltage characteristics are accurate and highly effective for representing TDM solar cell current. The accuracy of the parameter estimates obtained with the application of the proposed algorithm, considering both analytical solutions and the iterative approach, is compared with existing literature results. It is shown that the proposed algorithm outperforms existing algorithms in solar cell parameter estimation across both the analytical and iterative approaches for current-voltage characteristics. Remarkably, for the RTC France solar cell, the SOLAREX MSX 60 solar module, and the PHOTOWATT-PWP 201 solar module, the obtained Root Mean Square Errors (RMSE) are 0.00075141, 0.01157153, and 0.0010578, respectively. These results are currently the best reported in the literature. [ABSTRACT FROM AUTHOR]

This research aims to develop a business diversification strategy through a virtual cloud computing lab to reduce the risk of bankruptcy of SMEs. The method used in this research is mixed research in collaboration with quantitative and qualitative approaches to develop products and find out how much people accept the products developed. To see the acceptance of the developed website, the researcher used the technology acceptance model (TAM model). After forming a good model, a partial test (t-test) is carried out for decision-making. Based on the findings of data analysis, it was found that existing micro, small, and medium enterprises (MSMEs) lacked information and media to assist them in diversifying their business. Based on these needs, a website for MSMEs has been developed that has been validated and obtained results in the "good" category. Researchers conducted tests for the acceptance of websites developed with structural perceived usefulness, perceived ease of use, intention to use, and actual use with results showing the "good" category. From these results, it can be concluded that the website developed has a good reception in supporting MSMEs to reduce the risk of bankruptcy. [ABSTRACT FROM AUTHOR]

This study focuses on high-temporal-resolution Vertical Total Electron Content (VTEC) estimation over Nigeria, which is crucial for enhancing satellite-based applications. Utilizing RINEX, IONEX, and SP3 data from 2011 across 10 stations, the research integrates a novel VTEC model (LIMS) based on orthogonal transformation, achieving an unprecedented 10-minute temporal resolution sampling. The model incorporates multi-Global Navigation Satellite Systems (GNSS) constellations. Geomagnetic and solar activity impact assessments involve the Ap index, sunspot number, and DSt index. Specifically, the DSt index for March 16–18, 2015, analyzes the geomagnetic storm of St Patrick's Day. Validation compares LIMS with International GNSS Service (IGS), Center for Orbit Determination in Europe (CODE), and International Reference Ionosphere (IRI-2020) estimates, showing strong correlations during various conditions. Daily VTEC patterns reveal the lowest values in the early morning, a midday peak, occasional double peaks, secondary maximum, and post-sunset enhancements, especially during equinoxes. Seasonal analysis highlights the highest mean VTEC in September Equinox and December Solstice, and the lowest during June Solstice. Spectral analysis identifies prominent diurnal, semi-diurnal, and sub-diurnal frequency components. This research significantly advances the understanding of VTEC in Nigeria, offering a valuable tool for precise positioning, satellite communication, and space weather forecasting. Notably, 9 stations processed 2011 data, while one station from this group and an additional station were used for a 3-day storm analysis in 2015 due to data availability. [ABSTRACT FROM AUTHOR]

Teachers' beliefs are a teacher's subjective perspective about teaching practices in the classroom, which influence the actions and decisions that will be taken in facilitating student learning activities. A scale can serve as an effective tool for assessing teachers' beliefs in ethnomathematics-based numeracy learning. This study aims to evaluate teachers' belief in ethnomathematics-based numeracy learning scale. The data analysis will employ the Rasch model and involve 75 mathematics teachers from junior high schools in Central Java. The teachers' belief in an ethnomathematics-based numeracy learning scale was initially subjected to content validation by three experts. The cumulative percentage outcomes are according to the four dimensions, namely teachers' beliefs about numeracy, teachers' beliefs about the role of ethnomathematics in numeracy learning, teachers' beliefs about ethnomathematics-based numeracy teaching, and teachers' beliefs about ethnomathematics-based numeracy learning, amount to 90.28% for a total of 20 items. Following this, the researchers utilized the Rasch model analysis to investigate teachers' belief in an ethnomathematicsbased numeracy learning scale. The analysis involved the use of ten measurement features. Based on the results, it was deemed imperative to remove 30 individuals to maintain adherence to the predetermined criteria. Subsequently, the data obtained from the remaining 45 participants was analyzed using the Rasch model. The study of 20 teachers' belief items yielded three items, necessitating the exclusion of the privacy construct. The results indicate that the 17 questions possess robustness, validity, and reliability, rendering them suitable for assessing teachers' beliefs in ethnomathematics-based numeracy learning.

University students are an exclusive subcategory because most of them are young adults at a transformation period, training to stay independently while concurrently working toward completion of their professional degrees. Previous research reported that only 30% to 50% of university students meet the recommended proportion of exercise for health advantage. Mobile fitness apps are invented on purpose to support exercise. Many health advantages like preventing cardiovascular diseases and diabetes, it will marshal exercise and as mobile motivational tools because motivation is a major barrier to exercise. The present study was designed to investigate and compare the exercise intensity between the mobile fitness app users and none-users. The secondary purpose was to examine and compare the exercise intensity between gender from the university students. A total three hundred fifty-five university students were recruited in the study. The International Physical Activity Questionnaires- Short Form (IPAQ-SF) was used to collect exercise intensity of the participants in current study. All participants have been briefed on the objectives of this study and agreed to answer the International Physical Activity Questionnaires (IPAQ) and signed an informed consent form. The independent t-tests to determine the differences of the exercise intensity between mobile fitness app users and nonmobile fitness users. Independent t-tests also to find-out differences exercise intensity between gender in the university students, the statistical significance was set at p < .05. There were significant differences of exercise intensity level between nonmobile fitness apps users and mobile fitness apps users [ t (352) = 2.82, p = .005, d = 0.28]. It means the nonmobile fitness apps users had a significant higher exercise intensity if compared to the mobile fitness apps users. There were significant differences of exercise intensity level between male and female university students [ t (352) = 4.54, p = .001, d = 0.48]. Current results are similar to many studies found that female students participated in less exercise than their male counterparts. [ABSTRACT FROM AUTHOR]

• First review report of black band disease in Indonesia. • 29 cases of black band disease are reported recently. • Black band disease is caused by more than one type of microorganism usually called a consortium of microorganisms dominated by Cyanobacteria. • Another stressor from environment and anthropogenic activity also affect black band disease. Coral reefs stand out as exceptionally diverse ecosystems globally, serving crucial roles as nurseries and nutrient sources for marine life. Beyond their significance for marine ecosystems, these reefs play a vital role in shielding humans from erosion by acting as barriers against waves and storms. Unfortunately, the existence of coral reefs faces a threat from black band disease, particularly in Indonesia. This disease can lead to a rapid decline in coral reefs, characterized by microbial mat presence containing filamentous cyanobacteria consortium, resulting in tissue loss, lesions, and mortality. The limited awareness of this disease in Indonesia compounds the issue. In this review, we aim to present comprehensive information on black band disease, covering its definition, historical context, cases in Indonesia, and potential contributing factors, drawing from secondary sources. There are 29 documented cases of black band disease in Indonesia, scattered across Sumatra, Java, Sulawesi, NTT, and Papua, with Acropora and Montipora being the most frequently affected coral genera. Given the relatively silent nature of these cases, it is imperative to bring greater attention to black band disease in Indonesia. Microbiome engineering emerges as a suggested treatment. This literature review serves to enhance awareness of black band disease and marine biodiversity in Indonesia. [ABSTRACT FROM AUTHOR]
