Research ArticleOpen accessIn the abstractPhytochemical Composition, Antibacterial, and Antioxidant Properties of Foeniculum vulgare Essential OilSaif M. Dmour, Saqr Abushattal, Sultan Ayesh Mohammed Saghir et al.This study intended to inspect the phytochemical composition and bioactivity of Fennel (Foeniculum vulgare) Seed Essential Oil (FSEO) from Jordan. The EO was extracted via hydrodistillation from air-dried samples with 4.42% (v/w) yield. Twenty compounds, constituting around 98.5% of the EO were identified using Gas Chromatography-Mass Spectrometry (GC-MS). Estragole (47.15%) and Anethole (36.2%), appeared as predominant oxygenated monoterpenes compounds in … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 1 Aug 2025 · 4,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Evaluation of Synergistic Antibacterial Effects in Blended Essential Oil against Gram-Positive and Gram-Negative PathogensMin-Gi Kwon, Jae Kyung KimThe rising emergence of multidrug-resistant bacteria has heightened the search for novel antibiotic agents. Essential Oils (EOs) are complex combinations of volatile organic compounds generated by plants, with many exhibiting significant antimicrobial properties. This study evaluates the antibacterial movement of single and blended EOs against representative gram-positive bacteria Staphylococcus aureus and Methicillin-Resistant S. aureus (MRSA) and gram-negative bacteria Escherichia coli … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 7 Jul 2025 · 5,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantitative Analysis of Hypothalamic Proline-Rich Peptide-1 in Blood Serum of Patients with Malignant TumorsNarine Tumasyan, Silva Abrahamyan, Nune Kocharyan et al.The proline-rich-peptides are a class of neurosecretory hypothalamic bioactive polypeptides derived from cattle and comprise the content of bovine posterior pituitary neurosecretory granules. These peptides are co-validated through a single precursor protein neurophysin-vasopressin-associated glycoprotein. Proline-Rich-Polypeptide-1 (PRP-1) is a 15-amino acid peptide with anti-neurodegenerative, immunoregulatory, hematopoietic, antimicrobial, and antitumor activity. The aim of this study, accordingly, is to elaborate an assay … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 27 Nov 2025 · 2,283 accessesView PDFCite
