Research ArticleOpen accessIn the abstractProduction of an Achillea millefolium (Yarrow) Toothpaste to Combat Gum and Tooth PainMunashe K. F. Chakamanga, Ashley Kumalo K, Dirk Hamadziripi MGum inflammation also known as gingivitis is primarily caused by the accumulation of dental plaque that forms on teeth. The inflammation triggers pain in the gums and surrounding tissues due to increased blood flow and immune activity aimed at combating the bacterial infection. Thus, this study was carried out to investigate the efficacy of Yarrow-based toothpaste in reducing gum inflammation. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 9 Oct 2026 · 440 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 · 2,287 accessesView PDFCite
