Research ArticleOpen accessIn the abstractImmunomodulatory and Antioxidant Effects of Stachys Japonica Miq. Ethanol Extract on Cyclophosphamide-Induced Immunosuppressed Mice and its Phytochemical CompositionXueping Jiang, Jianglong He, Yanjun Chen, Fang WangStachys japonica Miq. is an edible wild botanical drug and a traditional medicine in China. This study focused on examining the phytochemical profile and antioxidant properties of the ethanol extract of S. japonica Miq (SJEE) in vitro, as well as its immunomodulatory and antioxidant activities in cyclophosphamide (Cy)-induced immunosuppressed mice. The SJEE was analysed by UPLC-HRMS/MS. 36 Polyphenols, including flavonoids, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 13 Apr 2026 · 1,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractsuPAR as an Inflammatory and Preclinical Atherosclerotic Marker in Hypovitaminosis DShravan Ajith Panchwadkar, Sudha Kuthethur, Neelam Manjunath Pawar et al.The mechanistic link between inflammation and atherosclerosis highlights the critical role of immune modulation in cardiovascular disease. The soluble urokinase plasminogen activator receptor (suPAR), an immune-derived factor, has recently emerged as a non-specific inflammatory marker across chronic diseases and infections. All cells within the atherosclerotic arterial wall can express uPAR and release urokinase, which plays a key role in the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 30 Mar 2026 · 1,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractPurification, Structural Characterization and Anti-Aging and Stress Activities of Cordyceps Mycelium Polysaccharides from Paecilomyces HepialiXiaokang Hu, Huixiu Ma, Guicai Chen et al.This study identified and characterized the bioactive polysaccharide components from Cordyceps mycelium powder (CMP) derived from Paecilomyces hepiali, evaluating their anti-aging and stress-protective activities. Initial screening using Drosophila melanogaster revealed that crude Cordyceps polysaccharides (CCP) exhibited comparable effects to CMP and Cordyceps aqueous extracts (CAE) on natural lifespan and UV stress resistance, suggesting CCP as the primary bioactive component. CCP … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotentiometric Biosensor for Highly Toxic Pb (lead) and Cd (cadmium) Detection in Milk Using Layer-by-Layer ImmobilizationZhainagul Kakimova, Klara Zharykbasova, Aitbek Kakimov et al.Milk contamination with heavy metals such as lead (Pb) and Cadmium (Cd) poses a serious threat to public health, particularly in industrial regions. To address the need for rapid and on-site detection of these contaminants, a potentiometric biosensor was developed for the quantification of Pb²⁺ and Cd²⁺ ions in milk and dairy products. The biosensor functions by measuring the change … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 8 Feb 2026 · 1,480 accessesView PDFCite
Research NotesOpen accessIn the abstractNuciferine Attenuates Cigarette Smoke-Induced Senescence in HepG-2 Cells via the miR-217/SIRT1/Nrf2 PathwayYun-Hong Zhao, Yi-Meng Ge, Wei-Jia Xu et al.The lotus leaf, widely used in both medicine and cuisine, contains bioactive compounds with therapeutic potential. Nuciferine (NF), an active constituent of significant importance, is extracted from the lotus leaf. The present study sought to uncover the molecular pathways through which Nuciferine (NF) mitigates cellular senescence triggered by Cigarette Smoke Components (CSCs) in HepG-2 cells, employing an experimental model where … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 4 Oct 2025 · 2,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cross-Sectional Study of the Prevalence of Hepatitis C Virus InfectionOmar Atrooz, Rehab Thunibat, Ihssan AtroozLiver pain is increased by hepatotropic viruses, such as the Hepatitis C Virus (HCV). This illness can progress to cirrhosis and hepatocellular cancer. This study aims to determine the prevalence of hepatitis C in the Southern Jordanian cities (Karak and Tafilah) as well as the correlations between alanine Aminotransferase (ALT), Aspartate aminotransferase (AST), age and gender in hepatitis C patients. … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 5 Jul 2024 · 4,414 accessesView PDFCite
