Abstract

BACKGROUND: The acute Hepatitis B virus (HBV) infection usually ceases before six months, but chronic infection that lasts for more than six months might develop into liver cirrhosis and hepatocellular carcinoma (HCC). Viral particle load, HBV genotypes and association to the HBV x (HBx) gene mutations are the probable factors related to HCC occurrence. The mutation which leads to HBx T118N was found as the second most common HBx mutation in Indonesia, as compared to the known cancer-related HBx K130M/V131I mutant. However, the effect of T118N mutation and its combination with K130M/V131I on human hepatoma cells has not been elucidated well. Hence, this study was conducted to dissect the role of HBx T118N and its mutant combination in colony formation, as compared to the wild type HBx and cancer-related HBx K130M/V131I.METHODS: In this study, the genes encoding wild type HBx, HBx T118N, and HBx K130M/V131I mutations were obtained as synthetic gene. Meanwhile, the gene encoding HBx T118N/K130M/V131I mutations was successfully generated using site-directed mutagenesis. The optimum condition for colony formation assays was determined through Zeocin sensitivity test of HepG2 cells.RESULTS: Selection of HepG2 cells using Zeocin was determined at 200 µg/mL. Colony formation assays performed upon expression of HBx T118N and HBx T118N/K130M/V131I mutant proteins showed reduced colony numbers as compared to the expression of wild type HBx, similar to the effect from HBx K130M/V131I mutant expression.CONCLUSION: The HBx T118N and HBx T118N/K130M/V131I mutation caused less colony formation of HepG2 cells, similar to the K130/M131I mutation. This indicates a possible role of the T118N mutation in liver cancer development.KEYWORDS: colony formation assay, hepatitis B virus, HBx, T118N, K130M/V131I

Abstract

National drug resilience is a fundamental pillar for achieving health independence and sovereignty in Indonesia. Strengthening this resilience has become a strategic mandate outlined in Law No. 17 of 2023 on Health, emphasizing the critical role of producing pharmaceuticals, vaccines, medical devices, and natural-based medicines to support the national healthcare system. This article examines the regulatory aspects, implementation, and challenges of realizing national drug resilience through a normative juridical approach. The integration of progressive legal theory, utilitarianism, and the welfare state model is the primary analytical framework for evaluating policy effectiveness. This approach is reinforced by a human rights perspective, particularly the right to health as enshrined in Article 28H of the 1945 Constitution and international frameworks such as ICESCR. The findings highlight that synergy among adaptive legal policies, strengthening biodiversity-based research and innovation, and supporting local industries are key to reducing dependence on imported materials and enhancing global competitiveness. This article contributes to local legal literature by integrating legal theory with human rights frameworks in the context of pharmaceutical policy while offering practical recommendations for supporting sustainable drug resilience policies. It provides a theoretical and strategic foundation for bolstering the national healthcare system through an inclusive and progressive legal approach.

Abstract

Wound healing is a complex biological process requiring adequate nutritional support, particularly proteins, amino acids, fatty acids, and essential minerals. Snakehead fish (Channa striata) has been traditionally consumed in Southeast Asia to accelerate recovery after surgery and childbirth. Emerging evidence suggests that its nutritional composition plays a pivotal role in tissue repair. The aim of this systematic review was to consolidate evidence on the nutritional composition of C. striata and elucidate its mechanisms of action in wound healing based on preclinical and clinical studies. A systematic search was conducted across PubMed, ScienceDirect, ProQuest, and Google Scholar for studies published between 2000 and 2023, following PRISMA 2020 guidelines. Eligible studies included biochemical analyses, in vitro and in vivo preclinical studies, and clinical trials assessing the wound-healing effects of C. striata. Data extraction covered nutrient composition, study design, wound-healing parameters, and mechanistic pathways. Out of 2898 identified studies, 22 of them met the inclusion criteria: ten biochemical composition studies, nine preclinical investigations, and four clinical trials. C. striata extract demonstrated high levels of albumin (0.76–10.73 g/100 g), essential and non-essential amino acids (notably glutamic acid, arginine, and glycine), fatty acids (palmitic, arachidonic, linoleic), and minerals such as zinc and copper. Preclinical models consistently showed enhanced fibroblast proliferation, epithelialization, tensile strength, and collagen deposition. Clinical studies in post-cesarean patients reported significant improvements in wound healing scores, uterine involution, pain reduction, and biomarker modulation (VEGF, IL-6, MMP-9). In conclusion, C. striata exhibits promising wound-healing potential attributable to its rich nutrient profile and multi-pathway mechanisms involving collagen synthesis, angiogenesis, and immunomodulation. However, the limited number of clinical trials underscores the need for larger, well-designed studies to confirm its translational efficacy in human wound care.

Abstract

This article examines the gut–brain axis in the pathophysiology of type 2 diabetes as a complex communication network that shapes glucose metabolism, systemic inflammation, gut hormone function, and eating behavior. By integratingevidence from metagenomic, neuroendocrine signaling, and modern pharmacotherapy studies, the article argues that type 2 diabetes is not merely a glycemic disorder, but also an internal ecological disruption involving microbiota interactions, theenteric nervous system, the vagus nerve, and metabolic regulatory centers in the brain. This perspective also highlights the clinical implications of emerging therapeutic agents such as GLP-1 agonists and dual GIP/GLP-1 agonists. This articleconceptualizes type 2 diabetes as an interorgan communication disorder that can be ameliorated through multilevel interventions including microbiota modulation, restoration of incretin, and precision nutrition strategies.

Abstract

Indonesia’s juvenile criminal justice system has embraced diversion and restorative justice as foundational principles following the enactment of Law No. 11 of 2012 on the Juvenile Criminal Justice System. This study critically examines the legal frameworks underpinning these principles, explores the policy gaps, and evaluates the implementation challenges that have emerged in practice. Employing a socio-legal qualitative methodology, this paper reviews statutory provisions, policy documents, and empirical research findings on diversion and restorative justice in Indonesia. The results reveal that while Indonesia’s legal reforms align with international standards on juvenile justice, significant inconsistencies persist in the practical application of diversion policies. Key barriers include uneven regional implementation, lack of standardized procedures, insufficient training for law enforcement, and societal resistance rooted in a punitive legal culture. The discussion offers a comprehensive analysis of these challenges and suggests strategic pathways to strengthen the restorative justice framework. The paper concludes by recommending policy reforms that incorporate local wisdom, enhance institutional capacity, and promote community involvement to ensure sustainable and effective juvenile justice practices in Indonesia.
