Synthesis and Characterization of Graphene-Based Hydroxyapatite Using Hydrothermal Method for Its Biomedical Application
Abstract: Developing bone implant materials that combine biological compatibility with mechanical strength remains a major challenge in orthopedic research. Hydroxyapatite (HAp) closely mimics bone mineral and supports cell growth, but its brittleness limits load-bearing applications. To address this, a quaternary nanocomposite of hydroxyapatite (HAp), graphene (Gr), zirconia (ZrO2), and ferrocene (Fc) (Hap-Gr-ZrO₂-Fc) was synthesized through a one-step hydrothermal process. Graphene and zirconia provided reinforcement, while ferrocene contributed structural stability and carbon …

Epigenetic Modifications in Health, Disease, and Precision Therapeutics (From Genome to Epigenome)
Abstract: Introduction: Epigenetic alterations play a crucial role in regulating gene expression in both normal physiological and disease states. These reversible modifications—such as DNA methylation, histone acetylation, phosphorylation, ubiquitination, and chromatin remodelling—are increasingly implicated in complex diseases including cancer and neurodegenerative disorders. Despite advances in standard therapeutic approaches, patient responses remain variable, largely due to genetic heterogeneity and epigenetic dysregulation. This highlights the need for incorporating epigenetic understanding into personalized medicine. …
