Abstract

A seismic event of magnitude 7.5 struck the Palu region in Central Sulawesi on September 28, 2018, precipitating a subsequent calamity in the form of a tsunami measuring 4-7 meters in height. This catastrophe was further compounded by the occurrence of liquefaction, leading to extensive devastation and a significant loss of life. In order to identify areas susceptible to liquefaction, it is anticipated that the employment of the gravity method, renowned for its capacity to discern density fluctuations associated with the mass of voluminous materials over a considerable detection range, will prove instrumental. The investigation of parameters and the characterization of liquefaction phenomena in regions previously afflicted by liquefaction disasters can be instrumental in devising strategies for mapping zones that are predisposed to such occurrences. The present study seeks to employ geophysical methods, specifically the gravity method, to delineate zones with the potential for liquefaction within the Lolu Village at Palu City, Central Sulawesi. Through the application of techniques designed to isolate regional and residual anomalies, it is envisaged that a clearer understanding of anomalies situated in shallower regions can be attained, with a specific focus on residential areas. Notably, due to liquefaction, approximately half of the residential areas have shifted a considerable distance of around 132 meters from their original positions. To facilitate the interpretation of subsurface layers, two-dimensional cross-sections are modeled to intersect the displaced and stationary areas. The residual map reveals discernible variations in anomaly values, with lower values observed in the areas that experienced liquefaction-induced movement. Subsurface modeling further demonstrates the presence of three distinct rock layers, namely a sandy layer, a gravel layer, and a rock layer. Additionally, the modeling depicts the formation of canals composed of hard rock, exhibiting varying thicknesses within the surface layer as a consequence of the liquefaction event in 2018. The existence of these canals serves as an indicator that when the sandy layer becomes saturated with water, it will flow along the topographical gradient, following the path of the subterranean canals that have formed.

Abstract

Alstonia scholaris L. R. Br is one of the traditional plants that contain natural antioxidant compounds which are thought to be able to repair damage to the liver cells of mice (Mus musculus) infected with Plasmodium berghei strain ANKA. This study aimed to determine the effect of methanol extract of Alstonia scholaris L. R. Br stem bark on levels of SGPT enzymes and liver cells of mice (Mus musculus) infected with Plasmodium berghei strain ANKA. Mice with a body weight of 20-30 g were infected with Plasmodium berghei as much as 0.1 ml per head and left until the percentage of parasitemia reached 1-5%. Then mice (Mus musculus) were given methanol extract of Alstonia scholaris L. R. Br stem bark at doses of 1, 10, 100, and 200 mg/kg BW for 4 consecutive days. After that, surgery was performed to take blood to observe SGPT enzyme levels and mice liver cells to be prepared with Hematoxylin Eosin (HE) staining. The results of ANOVA showed that the methanol extract of Alstonia scholaris L. R. Br stems bark doses of 1 mg/kg BW, 10 mg/kg BW, 100 mg/kg BW and 200 mg/kg BW could reduce SGPT enzyme levels and repair damage to the liver cells of mice infected with Plasmodium berghei ANKA strains

Abstract

Red ginger (Zingiber officinale var. Rubrum) is a commonly used rhizome known for its fragrant and spicy taste. It contains gingerol and shogaol compounds that have antipyretic effects by inhibiting prostaglandin formation and stimulating the production of interleukin-10, an endogenous antipyretic. This study aimed to evaluate the potential of gingerol and shogaol compounds as antipyretic drug candidates through reverse docking techniques targeting interleukin-10 (IL-10). Ten natural compounds from red ginger were predicted for their potential as antipyretic drugs and docked with the IL-10 receptor protein using various computer programs. The molecular docking results showed that (6)-shogaol had four amino acid bond residues that were the same as the ibuprofen control compound, indicating its potential as an antipyretic drug candidate. Furthermore, (6)-shogaol had the same binding affinity as the control compound and was safe for oral consumption based on pharmacokinetic and toxicity tests using Lipinski's Rule, Toxtree, and admet-T. These findings suggest that (6)-shogaol is a promising antipyretic drug candidate compared to other compounds. In conclusion, this study identified the potential of (6)-shogaol as an antipyretic drug candidate through reverse docking techniques targeting interleukin-10. Red ginger could provide a natural alternative for antipyretic drugs, and further research is recommended to explore the role of gingerol and shogaol compounds in targeting other proteins

Abstract

In this study, we present the validation of the AFCI (Analysis and Identification, Find Color, Color Composition, and Implementation) model as a problem-based approach to enhance the quality of multicolor output in open and distance learning materials. The primary objective was to evaluate the reliability and validity of the AFCI model, specifically designed to incorporate two-color separation techniques aimed at reducing costs while improving the quality of multicolor content. Our research encompassed the examination of printed modules and samples across diverse subject areas, including Basic Chemistry, Architecture, Enterprise System Design, and Teacher Profession. To establish the validity of the AFCI model, a comprehensive validation process was conducted, involving focused group discussions with experts specializing in graphic design, printing, and educational materials. The outcomes of this rigorous validation process revealed substantial validity coefficients (rα visibility = 0.98, rα attractiveness = 0.97, rα convenience = 0.91, rα emphasis = 1), affirming the model's effectiveness. Furthermore, the internal consistency of the AFCI model was confirmed with a Cronbach's Alpha coefficient of 0.86. This research significantly contributes to the realm of open and distance learning by introducing an innovative model for improving multicolor content quality. The AFCI model's successful validation underscores its potential to benefit practitioners and educators in developing high-quality teaching materials, thereby enhancing the overall learning experience in open and distance education.

Abstract

In the recent years, the alternative intravascular imaging modalities that are most frequently employed to direct and optimize PCI have been intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The comparative effectiveness of OCT-guided vs IVUS-guided PCI is still up for debate. The purpose of this study was to conduct a systematic review and meta-analysis of all available studies comparing OCT-guided versus intravascular ultrasound (IVUS)-guided PCI. Electronic journals searching were performed in PubMed, ScienceDirect, and Cochrane from January 2015 to March 2023 to identify randomized control trial (RCT) studies that compare OCT‐guided PCI to IVUS‐guided PCI. Meta-analyses were performed on included studies and Odds ratio (OR) and 95% Confidence Interval (CI) were estimated using Review Manager v5.4. A total of four RCT enrolling 1316 participants were included in our analysis. There is no statistical significance was observed in the OCT versus IVUS comparison on all cause mortality [OR = 1.75, 95% CI (0.52, 5.88), p = 0.37], cardiovascular mortality [OR = 1.40, 95% CI (0.27, 7.11), p = 0.69], MACE [OR = 1.04, 95% CI (0.63, 1.71), p = 0.88], ST [OR = 0.94, 95% CI (0.16, 5.52), p = 0.95], TLR [OR = 0.77, 95% CI (0.39, 1.50), p = 0.44], and TVR [OR = 1.19, 95% CI (0.68, 2.07), p = 0.54].
