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
Research ArticleOpen accessIn the abstractStudy on the Enhancement of Hypoglycemic and Antioxidant Activities of Compound Herbal Tea through Solid-State FermentationQing Liu, Xiaowen Que, Yueping Yang et al.This study utilized Aspergillus niger KY2295 for the Solid-State Fermentation (SSF) of a compound tea made from Cinnamomum cassia bark, Glycyrrhiza glabra, Morus abla L. leaf, and Crataegus oxyacantha L. to enhance its hypoglycemic effects. The fermentation process was optimized using single-factor experiments and a Central Composite Design (CCD), with α-amylase and α-glucosidase inhibitory activities as evaluation indices. Following fermentation, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 20 May 2025 · 5,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractInhibitory Effects of Artemisia afra Extracts on the Bio-Activity of Banana TyrosinaseTsholofelo Motshologane, Jacobus Pieter Hough Van WykMelasma, formerly known as chloasma, is an acquired pigmentary condition, occurring most commonly on the face of humans. This disorder, which is more prevalent in females and darker skin types, is predominantly attributed to Ultraviolet (UV) exposure and hormonal influences. This condition is caused by an over-production of melanin, a pigment that gives color to the skin, hair, and eyes … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 18 Jan 2025 · 4,621 accessesView PDFCite

Research ArticleOpen accessIn the abstractProtein Secondary Structure Prediction using Hybrid Recurrent Neural NetworksRomana Rahman Ema, Akhi Khatun, Md. Alam Hossain et al.The most important and challenging problem in bioinformatics is protein secondary structure prediction. The molecules of all protein organisms have three-dimensional (primary, secondary, 3-D) structures which are completely recognized by the sequence of amino acids. Protein secondary structure attributes to the polypeptide backbone of the local configuration of proteins. Most generally, the second-level prediction is indicated such as: If there … …Journal of Computer Science, Vol. 18, Issue 7 · 14 Jul 2022 · 7,339 accessesView PDFCite
