Therapeutic effects of chlorogenic acid on allergic rhinitis through TLR4/MAPK/NF-κB pathway modulation
Authors: Xu Xiaoyan , Wang Lei , Wu Guangyao , Li Xixia
Published: December 2024

Chlorogenic acid (CGA) exhibits promising anti-inflammatory properties, making it a potential therapeutic agent for inflammatory conditions and allergic rhinitis (AR). This study aimed to evaluate the therapeutic effects of CGA on inflammation in RAW264.7 macrophage cells and on AR in mice. RAW264.7 cells were treated with lipopolysaccharide (LPS) to induce inflammation and cultured with varying concentrations of CGA, a Tlr4-silenced gene (shTlr4) transfection, and the MAPK/NF-κB pathway activator diprovocim. Cell viability was assessed using the CCK8 assay, while levels of nitric oxide (NO), TNF-α, and IL-6 were measured by Griess colorimetry, immunofluorescence, and ELISA. Expression and phosphorylation levels of the MAPK/NF-κB pathway were evaluated using qPCR and western blotting. Additionally, ovalbumin (OVA)-induced AR mice received different doses of CGA, and Toll-like receptor-4 (Tlr4) overexpression was induced. In vitro, CGA treatment significantly reduced LPS-induced cell activity, NO, TNF-α, and IL-6 secretion, and downregulated Tlr4, p-p38, p-p65, and p-IκB expression. Tlr4 inhibition suppressed cell activity and inflammation by blocking MAPK/NF-κB pathway activation. Conversely, Tlr4 overexpression counteracted the effects of CGA, increasing cell activity and inflammatory factor concentration. In OVA-induced AR mice, CGA effectively alleviated allergic symptoms, reduced inflammatory factor secretion, and inhibited TLR4/MAPK/NF-κB pathway activity. These findings suggest CGA’s potential as an anti-inflammatory agent in RAW264.7 cells and AR models through modulation of the TLR4/MAPK/NF-κB pathway.

Published: December 2024

The extrusion bioprinting of collagen material has many applications relevant to tissue engineering and regenerative medicine. Freeform Reversible Embedding of Suspended Hydrogels (FRESH) technology is capable of 3D printing collagen material with the specifications and details needed for precise tissue guidance, a crucial requirement for effective tissue repair. While FRESH has shown repeated success and reliability for extrusion printing, the mechanical properties of completed collagen prints can be improved further by post-print crosslinking methodologies. Photoinitiator-based crosslinking methods are simple and have proven effective in strengthening protein-based materials. The ruthenium and sodium persulfate photoinitiator system (Ru(bpy)3/SPS) has been suggested as an effective crosslinking method for collagen materials. Herein, we describe the procedure our group has developed to combineextrusion-based 3D printing of type-1 collagen using FRESH technology with Ru(bpy)3/SPS photoinitiated crosslinking methods to improve the strength and stability of 3D printed collagen structures.

Canthik Kiai Rajamala is one of the heirlooms owned by the Keraton Kasunanan Surakarta. There are two Canthik Kiai Rajamala, each stored in the Keraton Surakarta Museum and the Radya Pustaka Museum. Surakarta is the only region traversed by the Bengawan Solo River that possesses a canthik, making it a distinctive and unique cultural heritage for the people of Surakarta. This research addresses the issue of how the meaning and value construction of Canthik Kiai Rajamala can be interpreted using Pierce’s semiotic triangle theory. Additionally, this study examines how contemporary Surakarta society perceives Canthik Kiai Rajamala. The aim of this research is to identify the cultural meanings and values of Canthik Kiai Rajamala, which are preserved in both museums. The interpretation of the object involves the community’s perspective on Canthik Kiai Rajamala, from its creation and use to its current status as a museum artefact. This study also focuses on the local wisdom system of the Surakarta society in interpreting the cultural traditions associated with Canthik Kiai Rajamala and its relationship with the environment and local customary community.
THE VOICE OF THE VOICELESS: COUNTERING THE FESTIVAL AND ELEVATING REYOG OBYOKAN AS CULTURAL CAPITAL
Authors:   Fakultas Ilmu Budaya, Universitas Jember, Tallapessy Albert
Published: December 2024

This article examines two performance models of Reog Ponorogo: The festival model and the obyokan model. These two competing models represent differing perspectives on one side, the interests of the artists and the community, and on the other, the interests of the state. By applying cultural studies theories, particularly those of representation and hegemony, this study analyzes data collected through observations of Reog performances at both festival and obyokan events, as well as interviews with artists and community members. The findings reveal that the obyokan model emphasizes an egalitarian spirit, allowing artists greater aesthetic freedom and providing the community with a sense of belonging in Reog culture. In contrast, the festival model has historically been associated with the state’s efforts to impose order on Reog artists and choreographies while simultaneously promoting tourism in Ponorogo.

Published: December 2024

Digital marketing provides a set of tools and strategies to influence purchasing intentions. The research proved that digital ads can positively influence purchasing intentions based on a set of factors. Several studies were conducted to use machine learning in predicting purchasing intentions. The paper demonstrates that digital marketing can generate positive purchasing intentions. However, digital marketing factors that can positively influence purchasing intentions are not widely considered in research that predicts purchasing intentions. This article aims to develop a classification machine learning model to predict the impacts of digital ads on purchasing intentions based on demographics and digital marketing factors. The used dataset was collected from individuals in Saudi Arabia by using a questionnaire. Two experiments related to feature extraction are applied, and ten different classification machine learning models are evaluated at each experiment. The voting classifier provides an accuracy of 92%, and the random forest provides an accuracy of 91%. They provide good and useful predictions. The results obtained can help marketers to target the right individuals in their digital marketing campaigns.
The bricks of Mathematical Research: from Antyquity to the Era of Artificial Intelligence
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Yusypiv Taras
Published: December 2024

Mathematical research began in ancient times when humanity faced the need for precise measurements and calculations to solve practical problems, leading to the emergence of disciplines such as arithmetic and geometry. A significant milestone in building mathematics as a logically rigorous and consistent theory was Euclid's work Elements, in which he introduced the axiomatics system: he substantiated the truth of the known geometric statements of the time by deriving them from axioms – basic statements accepted as true (based on intuitive reasoning). However, as was later revealed, there are mathematical propositions whose proofs or disproving may take centuries, and a vivid example of this is Fermat's Last Theorem, the truth of which was confirmed only over 350 years after the author wrote it in his notes. With the advent of new technologies such as neural networks, the process of mathematical discovery began to accelerate. Neural networks can model complex logical relationships and quickly explore possible solution variants. This opens new horizons for scientific research, allowing the combination of classical mathematical methods with innovative approaches that may significantly change the way mathematical problems are solved.

As is well known, power series-based methods are one of the pillars of mathematical analysis. For analytic functions, the power series can be easily obtained from Taylor's theorem in the form of Maclaurin series by calculating the derivatives of these functions at x=0. At the same time, it would be useful to be able to expand functions into series without using the concept of a derivative. Such expansions, in particular, would be helpful in calculating limits, which are fundamental to mathematical analysis. In the work of L. P. Myronenko and O. A. Rubtsova (2013), the idea was proposed that the properties of elementary functions can be used for series expansion, and the first terms of their power series expansions were obtained. In the work of V. I. Romanenko and A. V. Romanenko (2024), a generalization of this approach allowed for obtaining the series terms for sine, cosine, and exponential functions in a general form. In the article presented to the reader, the main results of the cited works are provided in a simplified form, supplemented by deriving a formula for the power series expansion of the tangent function. The presentation is structured in such a way that the core idea and the mathematical derivations are accessible to readers with knowledge of the school curriculum. The possibility of an algebraic approach to function series expansion might explain how the Indian mathematician Madhava (14th–15th century) managed to derive the first few terms of the series expansion for sine, cosine, and arctangent long before function analyses methods in the modern form.

Published: December 2024

This article explores the influence of various factors on the intensity of the chromatographic peak of 1,4-dioxane using gas chromatography with headspace analysis (GC-HS). The effects of adding water and sodium chloride to shampoo samples and the impact of headspace vial filling on peak height were examined. Experimental results showed that reducing the volume of vial filling significantly enhances the dioxane signal. Adding water to shampoo samples decreases the peak height while adding sodium chloride increases both peak height and area. Furthermore, increasing the amount of shampoo in the vial was observed to have minimal impact on peak height. A methodology for determining 1,4-dioxane in shampoo samples was validated, including checks for specificity, linearity, accuracy, and method convergence. The calculated data demonstrate that the methodology meets the requirements for precision and accuracy, with an analysis uncertainty of 8.9% and an average deviation of 3.7%, respectively. This confirms the reliability and accuracy of the method for determining dioxane in shampoo samples. The findings of this study are important for the quality control of 1,4-dioxane in cosmetic products. The data can also improve shampoo manufacturing processes and enhance product quality control.

Published: December 2024

This study investigates the mineralogical composition of radionuclide-rich beach sands along the coast of the Miocene Ezine-Ayvacık magmatic complex including Kestanbol pluton, in Western Anatolia. The distribution of the radionuclides show variations along the coast with the highest recorded radioactivity at Hantepe Beach, where specific activities of the 238U-, and 232Th-series are significantly high, while 40K concentrations are moderate. In contrast, the southern beaches, dominated by material from the Kestanbol pluton, have higher 40K concentrations but lower 238U-, and 232Th-series specific activities than Hantepe beach.
Using gamma spectrometry, bulk geochemical, and in-situ analyses, we provide a detailed assessment of the mineralogical composition of the sand samples and the primordial radionuclide concentrations of the different lithologies within the Kestanbol pluton, such as felsic veins, nepheline monzogabbro and tephriphonolitic dykes.
We suggest that thorite group minerals control the high radioactivity at Hantepe beach, and pegmatitic veins of the Kestanbol pluton are the main source rock for thorite minerals. However, all the products of Miocene magmatism in the region exhibit elevated radioelement and radionuclide enrichments suggesting that other accessory and rock- forming minerals are the potential contributors to the high natural background radiation in the area.
Catalog Replenishment Based on Statistical Method for Strong Earthquakes in the Triple Junction Area, Eastern Tibet
Authors: Wei Mengyi , Wu Jing , Gao Xinyu
Published: December 2024

The triple junction area, bordered by the Longmenshan, Xianshuihe, and Anninghe faults, is located at the southeastern corner of Songpan–Ganzi block, northern Tibet. In this area, a series of strong earthquakes occurred, including the 2008 Mw 7.9 Wenchuan, 2013 Mw 6.6 Lushan, 2014 Mw 5.9 Kangding, 2022 Mw 5.8 Lushan, and 2022 Mw 6.6 Luding. In addition, multiple hot springs with different temperatures are distributed along the faults in the same area. This study tries to figure out: (1) the necessity of catalog replenishment based on statistical method; (2) whether the special tectonic environment characterized by hot springs influences the evolution of aftershock sequences. A complete aftershock catalog is a fundamental data set for exploring these issues. However, the incompleteness of the catalog limits our understanding of aftershock evolution. Here, we applied a statistical catalog replenishment method to the five aftershock sequences, with the results showing that the replenishment method is helpful to improve the catalog completeness by producing more reasonable Omori law parameters. In addition, both the catalogs obtained from matched filter technique and the replenishment method have advantages and limitations, suggesting that combining two versions of catalog in aftershock evolution study is helpful. Finally, we revealed a negative correlation between the p-value of Omori law parameters and temperatures of hot springs, which may be useful to evaluate potential aftershock risks.

Published: December 2024

Coffee is one of the plantation crops that has high economic value, as a source of foreign exchange, as well as a source of income for less than one and a half million coffee farmers in Indonesia. Coffee is a prime crop that is a source of income for the community and local government in the Gayo Highlands. It is estimated that the coffee plantation area reaches 101,316 hectares with 48,000 hectares in Central Aceh Regency, 46,316 hectares in Bener Meriah and 7,000 hectares in Gayo Lues. Generally, the types of coffee grown in the Gayo highlands are Arabica and Robusta. One of the main obstacles in coffee plant cultivation is the attack of leaf rust disease caused by the Hemileia vastatrix fungus. This coffee leaf rust disease has developed in Indonesia since 1876, resulting in a decrease in production. The decline in coffee plant production due to leaf rust disease attacks reaches 25 to 35%. The purpose of this study was to determine whether shade density affects leaf rust fungus (H. vastatrix) attack and fruit production on Arabica coffee plants. This study was conducted in four community-owned organic Arabica coffee plantations in Central Aceh Regency with an area of ± 1 ha at an altitude of 1,100 to 1,300 meters above sea level. Some of the criteria observed on coffee plants in this study are coffee plants that have produced fruit with a plant height of 1.5 to 2m and 10-15 years old. On each land, plots were made at perm

Abstrak. Maggot adalah organisme yang berasal dari telur lalat black soldier fly dan merupakan salah satu organisme pembusuk. Lalat ini berperan sebagai salah satu pilihan penyediaan pakan dengan sumber protein yang tinggi, mudah dikembang biakkan, dan mudah ditemukan. Kandungan protein dan lemaknya yang tinggi memungkinkan larva BSF untuk digunakan sebagai bahan baku bioindustri, karena protein yang dihasilkan lebih ekonomis, lebih ramah lingkungan, dan memiliki nilai konversi pakan yang tinggi. Budidaya maggot larva BSF merupakan salah satu alternatif budidaya ternak yang sedang berkembang, yang dapat digunakan sebagai pakan dan dekompuser untuk pengelolaan limbah organik. Budidaya maggot memiliki dampak positif dan negatif yang dipengaruhi oleh beberapa faktor. Salah satu metode yang digunakan untuk menganalisis dampak lingkungan adalah Life cycle assessment (LCA), yaitu metode yang menyederhanakan cara untuk melakukan penilaian potensi dampak lingkungan berkaitan dengan kegiatan produksi atau layanan jasa. Kegiatan budidaya maggot merupakan kegiatan yang menguntungkan, namun dipengaruhi oleh cara dan sumber daya yang digunakan. Oleh karena itu, perlu dilakukan analisis dampak dan pendapatan pada suatu usaha budidaya maggot.Analysis of Income in the Maggot Cultivation Business (Case Study of the Maggot Cultivation Business in the BSF Farm Meta Maggot Business, Lambisnis Village, Banda Aceh City)abstrack : Maggots are organisms that come from the eggs of the black soldier fly and are one of the decomposer organisms. This fly serves as one of the options for providing feed with a high protein source, easy to breed, and readily available. The high protein and fat content allows BSF larvae to be used as raw material in the bioindustry, as the protein produced is more economical, more environmentally friendly, and has a high feed conversion value. The cultivation of BSF maggot larvae is an emerging alternative in livestock farming, which can be used as feed and a decomposer for organic waste management. Maggot cultivation has positive and negative impacts influenced by several factors. One of the methods used to analyse environmental impact is Life Cycle Assessment (LCA), which is a method that simplifies the way to assess the potential environmental impacts related to production activities or service provision. Maggot farming is a profitable activity, but it is influenced by the methods and resources used. Therefore, it is necessary to conduct an impact and revenue analysis on a maggot farming business.
