To understand how DJ-1 hydrolyzes cyclic 3-phosphoglyceric anhydride—a highly reactive, toxic cellular metabolite—researchers from Japan performed molecular simulations and biochemical assays, including mutational analyses, confirming DJ-1’s role in the pathogenesis of hereditary Parkinson’s disease. A mutant DJ-1 causes recessive Parkinson’s disease, but the molecular mechanism of this process has not been well studied. By revealing the amino acids involved in its catalytic activity, this work lays foundation for future functional studies on DJ-1.

Wastewater surveillance at treatment plants offers a low-cost, early warning method for detecting COVID-19. Researchers in Japan conducted an economic evaluation of a system for long-term care facilities that combines wastewater data with clinical testing thresholds to guide timely interventions. Their findings show that this approach could generate significant healthcare savings and improve outbreak response. The study supports wastewater surveillance as a scalable, cost-effective strategy for enhancing pandemic preparedness in vulnerable populations.

Artificial intelligence (AI) is transforming healthcare across multiple fields, and prostate cancer (PCa)  is no exception. A recent review conducted by researchers discusses the role of AI in clinical practice against PCa. According to this study, AI models enable early detection of PCa with high accuracy while minimizing errors. AI models used in molecular subtyping and precision medicine also offer personalized treatments—improving the overall quality of life of patients.
