Research ArticleOpen accessIn the abstractInvestigation of the Contribution of Late Embryogenesis Abundant (LEA) K Peptide in Enhancing the Expression of Lipase from Sphingobacterium sp.: In vitro and in Silico StudiesIbrahim Muhammad et al.Sphingobacterium sp. AB3 lipase is a psychrophilic enzyme with optimal lipolytic activity at pH 7 and 15°C. The cold-adapted properties of the lipase render it suitable for various low-temperature industrial applications such as biodiesel production, detergent formulation, and non-thermal food processing. Recent studies have shown that co-expression of LEA K peptide with AB3 lipase resulted in enhanced protein expression in … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 21 Nov 2024 · 4,569 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanism Analysis of Artemisinin and Artesunate as Lung Cancer Therapy Agents Through in Silico MethodDidik Harmoko, Vivitri Dewi Prasasty, Adi YulandiSeveral in vitro studies have focused on the ability of artemisinin and its derivatives to suppress lung cancer cells, but there are still many biological processes and mechanisms, such as the interactions between the active compounds (ligands) and receptors that are not well understood and require further research. Drug targeting for lung cancer will be more precise and the inhibition … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 15 Feb 2024 · 6,144 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Characterization and in Silico Analysis of Phytochemical Compounds from Plants with Immunomodulatory PotentialHermin Pancasakti Kusumaningrum, Rejeki Siti Ferniah, Siti Nur Jannah et al.The immune system works to protect the body against foreign antigens from microorganisms and abnormal cells. The use of herbal plants as immunomodulators are used to prevent disease attacks. TNFα and interleukin-6 are pro-inflammatory immune systems that cause disease in uncontrolled synthesis. Herbal plants as inhibitors of TNFα and interleukin-6 need to be identified molecularly to reduce the occurrence of … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 27 Nov 2025 · 1,954 accessesView PDFCite
Research ArticleOpen accessIn the abstractUPLC-Q-Exactive Orbitrap-MS Analysis of Anchusa italica Retz. Flowers: Molecular Docking, Dynamics Modeling, and Pharmacokinetics for Cardiovascular DiseaseLinyang Wang, Yan Chen, Ainiwaer Aikemu, Shuge TianThis study builds on prior UPLC-Q-Exactive Orbit rap-MS analyses of Anchusa italica Retz. Flowers (Airfs) to explore their anti-cardiovascular mechanis·ms and key bioactive markers. UPLC-Q-Exactive Orbitrap-MS identified 30 major compounds, including polyphenols and flavonoids with strong antioxidant activity. The potential active ingredients were then screened using Lipinski's rule of five, and a network pharmacology method was employed to construct an … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 25 Oct 2025 · 2,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractSocial Media-Facilitated Programming: An ARG Model for Collaborative ProgrammingAhmad Al-Jarrah, Abdel Karim Baareh, Ahmad Smadi, Roba JabaliInternet-based tools and social media are greatly developed in the tech world. Today, technology is widely accepted and used by all generations. These tools are great and very useful for students in terms of learning, collaboration and information sharing. We aim to present a model for learning programming in social learning environments with the context of the Affinity Research Group … …Journal of Computer Science, Vol. 17, Issue 4 · 15 Apr 2021 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractApoptosis in Yeast is Modulated by Clove Leaf Extract and Eugenol Potentially by Interfering Caspase YCA1Septyani Amini, Rika Indri Astuti, Irmanida BatubaraApoptosis is a process of cell death important for preventing the development of diseases such as cancer, neurodegenerative disorders, autoimmune, and cardiovascular disease. Apoptosis is reported to be potentially induced by antioxidant compounds, including phytoextract. Thus in this study, we determined the potential of apoptotic modulation in yeast cells by clove extract, which was rich in eugenol. Apoptotic in yeast … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 15 Sep 2022 · 5,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural and Substrate Interaction Properties of Alkaline Phosphatase from Paenibacillus sp. PSB04: In-Silico AnalysisHerman Umbau Lindang, Cahyo BudimanA Phosphate-Solubilising Bacterium (PSB) of Paenibacillus sp. PSB04 was previously isolated from the Sabah tropical rainforest in Malaysia. Interestingly, the genome sequence of the PSB04 strain harbored an Alkaline Phosphatase (AP) (EC 3.1.3.1) gene and was hypothesized to have unique structural characteristics. Therefore, this study aims to determine the AP three-Dimensional (3D) model and catalytic mechanism from Paenibacillus sp. PSB04 … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 16 Jul 2022 · 5,910 accessesView PDFCite
