Unlike conventional one-size-fits-all approaches, personalized strategies integrate host genetic profiles, pharmacokinetics/pharmacodynamics (PK/PD), microbial susceptibility, and biomarker data to optimize therapeutic outcomes while minimizing adverse effects and antimicrobial resistance (AMR). Conventional antibiotic administration often relies on empirical prescribing and fixed dosing, resulting in suboptimal exposure, treatment failures, and selection of resistant strains. Advanced drug delivery systems, including nanocarriers, liposomes, polymeric micelles, and stimulus-responsive platforms, enhance site-specific targeting, controlled release, biofilm penetration, and intracellular delivery, improving antibiotic efficacy and safety. Biomarker-guided selection and PK/PD-informed adaptive dosing allow dynamic adjustments based on infection progression and individual patient responses. Clinical studies demonstrate that these approaches reduce hospital stays, lower treatment failures, and minimize systemic toxicity. Future directions focus on integrating smart delivery systems, biosensors, artificial intelligence, and genomic/microbiome analyses to guide individualized therapy, enabling rapid, precise, and responsive antibiotic administration. Gene-targeted strategies, such as CRISPR-based antimicrobial payloads, offer additional potential to directly disrupt resistance mechanisms. Collectively, these innovations represent a shift toward precision antimicrobial therapy, addressing the limitations of conventional regimens, improving patient-centered outcomes, and mitigating the global AMR crisis.https://www.atjournal.ir/article_243077_bb88d5ec2f93b556426ba5d27743d195.pdfAmitisGen TECH Dev GroupAdvanced Therapies Journal3115-739482620260330Identification of Biomarkers Involved in Multiple Sclerosis: A Personalized Medicine Approach303824307910.22034/atj.2026.243079ENFatemeh-sadatRajaDepartment of biology, Islamic Azad University of Yadegar-e Imam ,Tehran , Iran.Journal Article20251218Multiple sclerosis (MS) represents a complex, immune-driven CNS condition marked by significant clinical and biological diversity, which complicates diagnostic and prognostic efforts. In recent years, the paradigm of MS research has evolved through rapid biomarker breakthroughs, transitioning from a reliance on traditional neuroimaging to holistic molecular and multi-modal profiling. Liquid-based indicators, such as glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL), and chitinase-3-like protein 1 (CHI3L1), have emerged as robust correlates of neuroaxonal damage and astrocytic involvement. Parallel to this, novel imaging features notably paramagnetic rim lesions and the central vein sign have increased diagnostic precision. Furthermore, the integration of multi-omics including genomics and metabolomics allows for a more granular understanding of the immune and degenerative pathways in MS. By leveraging systems biology and machine learning, researchers can now identify synergistic biomarker signatures that surpass individual markers in forecasting disease activity and therapeutic outcomes. However, achieving precision neurology requires overcoming obstacles in assay harmonization and clinical validation.https://www.atjournal.ir/article_243079_f7c46ced8c7d9a7991c8687f447d904c.pdfAmitisGen TECH Dev GroupAdvanced Therapies Journal3115-739482620260330The Role of NGS in the Advancement of Personalized Medicine Over the Past Two Decades394724308010.22034/atj.2026.243080ENMohammad SadraSamavatiDepartment of biology, Science and culture University, Tehran, Iran.SaeedPiri-GharaghieDepartment of chemistry, Asaluyeh branch of Islamic azad university, Asaluyeh, Iran.Journal Article20251222Next-generation sequencing (NGS) has revolutionized both clinical practice and biomedical research by providing rapid, highly accurate, and high-throughput genomic analysis. This review explores the technological progression of NGS, its contribution to mapping human genomic diversity, and its growing utility in areas such as precision medicine, oncology, pharmacogenomics, the diagnosis of rare disorders, and clinical decision support. By detecting single nucleotide variants, copy number changes, structural variations, and complex genomic rearrangements, NGS has deepened our understanding of disease heterogeneity and facilitated the creation of targeted treatment plans. In the field of oncology, the adoption of NGS has improved tumor classification, enabled therapies tailored to specific genetic profiles, and allowed for real-time monitoring via circulating tumor DNA analysis. <br> In pharmacogenomics, NGS has improved drug response prediction by identifying both common and rare variants affecting drug metabolism. Additionally, its application in rare diseases has shortened diagnostic odysseys and accelerated novel gene discovery. Despite challenges related to data interpretation, ethical governance, regulatory oversight, and data management, continuous technological innovation and multi-omics integration are strengthening the clinical utility of NGS.
