Research ArticleOpen accessIn the abstractImmunomodulatory and Antioxidant Activities of Selenium-Enriched Polysaccharides from Epimedium and Isatis IndigoticaRui Zhang, Jin Li, Jiajia ZhouThis study aims to investigate the effects of selenium modification on polysaccharides derived from two traditional Chinese medicinal herbs-Epimedium (Yinyanghuo) and Isatis root (Banlangen)-in enhancing immune function and antioxidant activity. The purpose is to explore the relationship between structure and function, providing a theoretical basis for the development of efficient plant-based functional antioxidants. Polysaccharides were extracted using an optimized enzymatic … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 3 Feb 2026 · 1,933 accessesView PDFCite
Review ArticleOpen accessIn the abstractTEC-Driven Mini Refrigerators: Recent Applications With Performance CharacteristicsTamer Guclu, Pinar Mert Cuce et al.Thermoelectric Cooling (TEC) technology has become a remarkable alternative in mini refrigerator applications in recent years, thanks to its lack of moving parts, silent operation, compact structure and environmentally friendly features. This study aims to examine the current usage areas, performance characteristics, and engineering challenges of TEC systems in mini refrigerator applications with a holistic approach. Experimental and theoretical studies … …Energy Research Journal, Vol. 14, Issue 1 · 23 Dec 2025 · 3,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Diversity of Isolated Mycobacterial Cultures in the Republic of Kazakhstan: Implications for Diagnostics and TreatmentAssiya Borsynbayeva, Kairat Turgenbayev, Gulzhauhar Sarsenova et al.The study of mycobacterial morphology in the Republic of Kazakhstan is relevant due to the increasing burden of tuberculosis and other mycobacterial diseases. The aim of this study was to comprehensively describe the morphological characteristics of different mycobacterial species identified in Kazakhstan, which will help to improve diagnostic methods and develop new approaches to treatment. Comparative and cross-cultural analyses were … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 1 Dec 2025 · 2,203 accessesView PDFCite

Research ArticleOpen accessIn the abstractDiscovery of a New Thermostable Chitinase from Streptomyces No. 6Xiaowen Que, Yonghong Bao, Qing Liu et al.Chitinases are a class of hydrolases that hydrolyze the β-1, 4-glycosidic bonds between N-acetyl-D-glucosamine (GlcNAc) in chitin. Among chitinases, thermophilic chitinases and thermostable chitinases have received extensive attention in recent years due to their ability to tolerate higher temperatures and maintain enzyme stability for a longer period of time. However, it has previously been observed that not all chitinases are … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 1 Aug 2024 · 5,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractFerulic Acid in Chinese Herbal Medicine: Regulating Autophagy for Oxidative Damage ReductionZhiyuan Lv, Qiaozhen Zhao, Shanbin Chen et al.Ferulic Acid (FA) is the primary functional component in herbal plants and traditional fermented foods. To comprehend the mechanism of action of ferulic acid, in terms of its regulation of autophagy, antioxidants and the inhibition of inflammatory pathways, the study was conducted. Oxidatively damaged human-derived hepatocytes were treated with FA and the processing concentration of FA is from 50-800 μm. … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 1 Jun 2024 · 5,483 accessesView PDFCite
