Biocatalytic Construction of a Chemical Exchange Saturation Transfer Magnetic Resonance Imaging Nucleoside Probe: Synthesis and Evaluation of 5‐Methyl‐5,6‐Dihydrothymidine

Advanced Synthesis &Catalysis, Volume 368, Issue 1, January 2026.
Al‐Hilfi et al. present a biocatalytic strategy for synthesizing 5‐methyl‐5,6‐dihydrothymidine (5‐MDHT), a sensitive MRI contrast agent. The study demonstrates that recombinant enzyme catalysis offers an efficient, sustainable, and eco‐friendly alternative to traditional chemical synthesis for producing clinically relevant imaging probes.

Ultrafine Molybdenum Wire Braided Neurointerventional Implants: Bridging Biodegradability and Neurovascular Safety for Stroke Treatment

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...
