Research ArticleOpen accessIn the keywordsIn vitro Anti Plasmodial Activity of Enicostemma littoraleSanket Soni, Sarita GuptaProblem statement: Malaria is a prevalent disease in India. The problem of drug resistance is worsening. Hence, new effective and affordable antimalarial drugs are very much needed. The long-established use of quinine and the more recent introduction of artemisinin as highly effective anti malarials demonstrate that plant species are an important resource for the discovery of new anti malarial agents. … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,707 accessesView PDFCite
Research ArticleOpen accessIn the abstractMarine-Derived Extracts as Economically Sustainable and Ethical Alternatives to Fetal Bovine Serum in HEK293 Cell CultureKian Kenneth Francisco Sanchez, Jennifer Seki-Wong et al.Fetal Bovine Serum (FBS) is a staple supplement in cell culture, providing key growth factors that promote cell health and proliferation. Since 1885, cell culture has been a cornerstone of both basic and applied research, leading to significant discoveries of cell communication and function. However, the use of FBS presents economic and ethical challenges. Millions of bovine fetuses are euthanized … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 7 Aug 2026 · 1,042 accessesView PDFCite

This study investigated the anthelmintic activity of a crude aqueous-ethanolic extract of C. xanthiifolia (CxEt), prepared from equal proportions of leaves and seeds, against the trematode Opisthorchis felineus in vitro. The effects of CxEt on the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,251 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytotoxicity Evaluation of Curcumin-FITC Conjugates in Granulosa Cells Isolated from Ovarian Follicles of Kampung Chicken (Gallus gallus domesticus)Sukarman Hadi Jaya Putra, Mansur S, UmarudinLinking curcumin to fluorescein isothiocyanate (FITC) results in a hybrid fluorescent marker (curcumin-FITC) that exhibits improved stability and sensitivity in detection. This study sought to evaluate the biological safety and cytotoxic effects of curcumin-FITC on granulosa cells obtained from ovarian follicles (2-5 mm, F1-F4 stage) of Kampung chickens. Following fluorescent labeling with different concentrations of curcumin-FITC (0-100 μg/mL), cell viability … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 14 May 2026 · 1,497 accessesView PDFCite
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
Research ArticleOpen accessIn the abstractUnveiling the Potential of Dombeya buettneri K.Schum As a Drug Agent: Molecular Docking of Compounds With Enzymes Linked to Diabetes and Neurodegenerative DiseaseEsther Emem Nwanna, Samuel Chima Ugbaja et al.This study investigated the mechanisms of Dombeya buettneri (snowball leafy) extracts on diabetes, hypertension, and neurodegenerative diseases. It compared extracts obtained using steep water (a by-product of corn wet milling) and aqueous water. The extracts were analyzed for total phenol, total flavonoid content, antioxidant activities such as FRAP, ABTS, NO, DPPH, iron-induced lipid peroxidation assay, degradation of deoxyribose (Fenton’s reaction), … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 1 Feb 2026 · 2,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractDihydroartemisinin Attenuates HBV-Induced Proliferation and Migration in LO2 cells via EMT Pathway ModulationYingde Nong, Caifang Ma, Wei Huang et al.Dihydroartemisinin (DHA), a derivative of artemisinin, possesses well-documented anti-inflammatory properties. This study investigated the inhibitory effects of DHA on hepatitis B virus (HBV)-induced cellular alterations in LO2 cells and elucidated underlying molecular mechanisms. Serum interleukin-6 (IL-6) levels were measured in HBV patients and analyzed for correlations with HBsAg, anti-HBs, and HBeAg. In vitro, LO2 cells were infected with clinical HBV … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 8 Jan 2026 · 2,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn silico and in vitro Structural Analysis on the Interaction of Calmodulin and Calmodulin-Binding Motif of FKBP35 from Plasmodium knowlesiSazlinawatie Aladin, Cahyo Budiman et al.FK506-binding protein 35 (FKBP35) is a peptidyl-prolyl cis-trans isomerase found in Plasmodium knowlesi, a zoonotic malaria parasite responsible for concerning cases of malaria infection in East Malaysia. This protein contains a segment known as the calmodulin-binding motif (Pk-CBM), which is predicted to facilitate interaction with calmodulin from P. knowlesi (Pk-CaM). Although this interaction is considered promising for future antimalarial drug … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 10 Mar 2025 · 4,846 accessesView PDFCite
