Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Influence of Permanent Magnetic Properties on Laser-Assisted Heating Magnetization for Magnetic MEMS
IEEE Access, 2023 When magnetic microelectromechanical systems (MEMS) devices utilize thin- or thick-film permanent magnets, the uniform magnetization of these magnets, owing to their flat-shape, generate a strong antimagnetic field and weak surface magnetic flux density.
