The evolution of medical biochemistry and clinical pathology: Integrating global milestones with the Balkan-Turkish scientific corridor

Background: The evolution of modern medicine and clinical biochemistry reflects historical, technological, and regional milestones achieved along the Balkan-Turkish scientific corridor. This review provides a comprehensive historical analysis of medicinal biochemistry, focusing on the breakthrough contributions of Balkan and Turkish scientists. Methods: A structured literature search was conducted across international and regional databases (PubMed, Scopus, Web of Science, TR Dizin, SCIndeks) covering publications up to 2026. Explicit inclusion/exclusion criteria, selection metrics, and geographic rationale were applied to systematically evaluate the contributions of the Balkan-Turkish corridor while maintaining methodological transparency and minimising selection bias. Standardised terminology »Medical Biochemistry« was applied across all sections. Results: Balkan and Turkish scientists have played a central role in biochemistry, highlighted by Nobel Prizes awarded to Leopold Ružička and Vladimir Prelog for organic synthesis/stereochemistry, George Emil Palade for ribosome mapping, Andrew Schally for neuroendocrinology, and Aziz Sancar for DNA repair mechanisms. Beyond Nobel recognition, milestone research includes Papanicolaou’s Pap smear, Aksoy’s link between benzene and leukaemia, and Benga’s discovery of erythrocyte aquaporins. In pediatric genetics, Pınar Özand and colleagues fundamentally reshaped the field through the Atlas of Metabolic Diseases. Furthermore, Berkeš, Tsolas, Danev, Laleli, Özer, Gruev, and Majkić-Singh’s institutional leadership drove the modernisation, quality control, and international accreditation of laboratory medicine in the region. Conclusion: The structural evolution of medical biochemistry highlights a shift from basic phenotypic observations to advanced molecular design. Breakthroughs along this regional axis not only advanced fundamental enzymology and metabolic pathology but also helped establish the international quality-control networks, educational frameworks, and accreditation standards that govern modern global healthcare.
