Abstract
This research aims to analyze the interaction between the culture of the people of Bengkulu City and Muhammadiyah education from a historical perspective, especially related to the controversy over the acceptance of religious purification teachings and the contribution of Muhammadiyah education to traditions that have long existed in society. This research was carried out using a historical approach through information from the figures involved and knowing the history of the development of Muhammadiyah education in Bengkulu City and several other primary and secondary sources. The study results found that Muhammadiyah education in Bengkulu City began with a debate between Muhammadiyah figures and kaum tuo (the old generation). Muhammadiyah's teachings focus on the purification of Islamic teachings in the culture of the Bengkulu City community, which contained many mystical and polytheistic (shirk) elements. Finally, the approach of Muhammadiyah figures led to cultural interaction with Islamic teachings as long as they did not conflict with Islamic teachings in religious activities, death, marriage, art, music, and curriculum in Muhammadiyah educational institutions through local cultural content. This research has implications for developing a curriculum based on local cultural values ​​so that it can improve character and identity among students.

Volatility is an important aspect of financial analysis that plays a crucial role in risk management and investment decision making. Modeling the volatility of financial asset prices is challenging due to its dynamic and complex nature. One approach used to address this problem is the GARCH model. In volatility problems, there is a tendency for structural changes in more complex data so that the GARCH model cannot be used, to overcome this, the Markov Switching GARCH (MS-GARCH) model is used to overcome the problem of changing the data structure. Furthermore, the Bayesian model is also used in combination with the MS-GARCH model to overcome the small sample size. This research uses Indonesia Sharia Stock Index (ISSI) return data from January 1, 2023 to December 31, 2023. From the comparison of the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) values to see the best model for forecasting ISSI data, the best model in forecasting ISSI data is the Bayesian MS-GARCH model with the smallest AIC value of -252.544 and BIC value of -237.0894, compared to the MS-GARCH model the AIC value is smaller than the Bayesian MS-GARCH model of -251.1048 and its BIC is -235.6502.

Volatilitas merupakah salah satu aspek penting dalam analisis keuangan yang memainkan peran krusial dalam manajemen resiko dan pengambilan keputusan investasi. Pemodelan volatilitas harga aset keuangan menjadi suatu tantangan karena sifatnya yang dinamis dan kompleks. Salah satu pendekatan yang digunakan untuk mengatasi masalah ini adalah model GARCH. Pada masalah volatilitas kecenderungan terjadinya perubahan struktur pada data yang lebih kompleks sehingga tidak bisa digunakan model GARCH, untuk mengatasi hal ini digunakan model Markov Switching GARCH (MS-GARCH) untuk mengatasi masalah perubahan struktur data. Selanjutnya digunakan juga model Bayesian yang dikombinasikan dengan model MS-GARCH untuk mengatasi jumlah sampel yang kecil. Penelitian ini menggunakan data return Index Saham Syariah Indonesia (ISSI) dari tanggal 1 Januari 2023 hingga 31 Desember 2023. Dari hasil perbandingan nilai Akaike Information Criterion (AIC) dan Bayesian Information Criterion (BIC) melihat model terbaik untuk meramalkan data ISSI, diperoleh model terbaik dalam meramalkan data ISSI adalah model Bayesian MS-GARCH dengan nilai AIC yang terkecil yaitu sebesar -252,544 dan nilai BIC yaitu -237.0894, dibandingkan pada model MS-GARCH nilai AICnya lebih kecil dibandingkan model Bayesian MS-GARCH sebesar -251,1048 dan BIC nya sebesar -235.6502.

This study explores the relationship between imports, exports, and exchange rates on inflation, with foreign exchange reserves acting as an intervening variable, using path analysis methods. This research arises from the need to understand how foreign exchange reserves can mitigate the impact of external instability on inflation, a topic often overlooked in previous studies. Secondary data were collected from various official sources, including Bank Indonesia and Badan Pusat Statistik (BPS), to analyze the variabels of import value (X1), export value (X2), exchange rate (X3), foreign exchange reserves (Y1), and inflation (Y2). Path analysis results show that import, export, and exchange rates have a significant impact on foreign exchange reserves, with a coefficient of determination (R²) 56.2%. Additionally, foreign exchange reserves play a crucial role in mediating this relationship, with a total determination coefficient (M) of 91.5% for the effect on inflation. This means that 91.5% of the variation in inflation can be explained by the combination of these variables. The study concludes that foreign exchange reserves are a one of key instrument in stabilizing inflation amid fluctuations in imports, exports, and exchange rates, and provides policy recommendations to strengthen foreign exchange reserves as a more effective economic stabilization strategy.

Penelitian ini mengeksplorasi keterkaitan antara impor, ekspor, dan kurs terhadap inflasi dengan cadangan devisa sebagai intervening variable, menggunakan metode analisis jalur. Penelitian ini berangkat dari kebutuhan untuk memahami bagaimana cadangan devisa dapat memitigasi dampak ketidakstabilan eksternal terhadap inflasi, yang sering kali kurang diperhatikan dalam studi sebelumnya. Data sekunder diperoleh dari berbagai sumber resmi, termasuk Bank Indonesia dan Badan Pusat Statistik, untuk menganalisis variabel nilai impor (X1), ekspor (X2), kurs (X3), cadangan devisa (Y1), dan inflasi (Y2). Hasil analisis jalur menunjukkan bahwa nilai impor, ekspor, dan kurs memiliki pengaruh signifikan terhadap cadangan devisa, dengan koefisien determinasi (R²) sebesar 56,2%. Selain itu, cadangan devisa terbukti memainkan peran penting dalam memediasi hubungan ini, dengan koefisien determinasi total (M) sebesar 91,5% untuk pengaruh terhadap inflasi. Artinya, 91,5% variasi inflasi dapat dijelaskan oleh kombinasi variabel-variabel ini. Penelitian ini menyimpulkan bahwa cadangan devisa merupakan salah satu instrumen kunci dalam menstabilkan inflasi di tengah fluktuasi impor, ekspor, dan kurs, serta memberikan rekomendasi kebijakan untuk memperkuat cadangan devisa sebagai strategi stabilisasi ekonomi yang lebih efektif

Authors: Hawraa Kareem Lifta  , Kadhim Enas Jawad 
Published: February 2025

The synergistic effect of the bergenin compound, derived from the Crassula ovata plant, and the docetaxel drug in vitro cell line was assessed in this study. The bergenin compound was extracted using a Soxhlet device and 85% ethanol, then was identified and isolated using a high-performance liquid chromatograph. Docetaxel is regarded as a potent chemotherapy treatment that was licensed in 1996 to treat a variety of cancers, including prostate cancer, by preventing microtubular depolymerization and reducing the impact of bcl-2 and bcl-xL gene expression. It is considered one of the most effective chemotherapy treatment for prostatic cancer. However, it has adverse effects, including febrile neutropenia or myelosuppression. This study aim to combine the docetaxel with new natural compound as there is no previous study on combination between the docetaxel and bergenin to reduce the therapeutic dose as much as possible and obtain same therapeutic effect .The results demonstrated that bergenin exhibits a good synergistic effect against prostatic cancer with IC50 equal to 26 as a phenolic compound that can induce G0/G1 cell cycle arrest, enhance the expression of Bax, decrease the expression of Bcl-2, and inhibit the PI3K/AKT/mTOR pathway. As revealed by the results, the inhibition effect of the combination (bergenin and IC50 docetaxel equal to 89,8) was 64, compared to an inhibition effect of 62 for 100 mcg of docetaxel and the data obtained were analyzed by one-way ANOVA with a significance level of "p < 0.05" .
Impact of Genomic Variation of NFE2L2 (rs6706649) on Serum Glyoxalase-1 Levels in A Sample of Iraqi Type 2 Diabetic Patients with Retinopathy
Authors: Sarah Hashim Mhaibes  , Shatha H Ali  
Published: February 2025

Nuclear factor erythroid-2-related factor-2 (NFE2L-2) is one important endogenous anti -oxidative stress signal pathway. Single nucleotide polymorphism (SNP) or genetic variants of NFE2L-2 may be accountable for the genesis of diabetic retinopathy. Glyoxalase-1 (Glo-1) is the rate-limiting enzyme in the detoxification of methylglyoxal (MG) into D-lactate. The activity of GLO1 is regulated by the transcription factor NFE2L2.The goal of this study is to ascertain whether there is an association between the rs6706649 of NFE2L2 gene variant with serum GLO-1 levels in a group of Iraqi diabetic patients diagnosed with diabetic retinopathy (DR). This study included ninety patients diagnosed with type 2 diabetes mellitus (48 females and 42 males), with ages ranging from 40 to 80 years. The participants were partitioned into two the following groups: Group A; 60 patients with type 2 diabetes mellitus diagnosed with DR (among them 29 patients with non-proliferative diabetic retinopathy (NPDR) and 31 patients with proliferative diabetic retinopathy (PDR)) and Group B: 30 patients without evidence of DR (DWR) considered as a control group were enrolled in the study. A non-significant difference in genotyping and allele carriage frequencies of rs6706649 (G/A) SNP between DR and DWR groups. Also, there was a non-significant difference between PDR and NPDR patients' groups in relation to the different genotypes and alleles of rs6706649 (G/A) of NFE2L2 gene. However, the changing from the wild genotype (GG) to mutant (AA) and heretogynotypes (GA) had significant positive correlation with the increased serum levels of GLO-1 and significant negative correlation with serum level of methylglyoxal (MG) in patients with diabetic retinopathy. Furthermore, pentosidine, carboxymethyl lysine (CML), GLO-1 and MG levels were significantly higher in DR when compared to DWR groups. The A mutant allele of rs6706649 (G >A) had significant positive correlation with the increased serum GLO-1 levels in DR group. Meanwhile, DR group had increased serum MG, GLO-1, pentosidine and CML levels. Hence, these biomarkers can serve as prognostic indicators for diabetic retinopathy.

Published: February 2025

The exact mechanism of action and which rheumatoid arthritis (RA) patients might benefit from Rituximab (RTX) are still questionable. One of the key elements in assessing the performance of a healthcare facility is patient satisfaction, which is a measure of how satisfied a patient is with the medical care he receives. This study aimed to evaluate the health-related quality of life and treatment satisfaction and their association with the responsiveness to RTX in RA patients. A cross-sectional study was conducted at the Center of Rheumatology in Baghdad- Iraq. The study enrolled 90 patients diagnosed with RA and receiving RTX intravenous infusion, for at least six months. The 28-joints disease activity score (DAS28) and clinical disease activity index (CDAI) were used to assess disease activity and RTX response. RA Impact of Disease (RAID) and Treatment Satisfaction Questionnaire for Medication (TSQM) were used to assess the health-related quality of life and treatment satisfaction, respectively. A total of 90 patients were enrolled in the current study and were divided into two groups (the RTX responders group included 50 patients and the RTX non-responders group included 40 patients) according to DAS28 and CDAI assessment. The patients in the responders group had a significantly better quality of life according to the RAID score (P-value<0.001), the effectiveness, convenience, and global satisfaction were significantly higher in the responders group compared to the non-responders group (P-values were <0.001 for all). There were significant negative correlations between the effectiveness, convenience, and global satisfaction with RAID, CDAI, and DAS28. Better health-related quality of life and satisfaction were achieved among RTX responders compared to others, some satisfaction parameters were affected by the history of RA and duration of disease
