Transporter‐Associated Therapeutic Efficacy of an SMVT‐Targeted Boron Carrier in Boron Neutron Capture Therapy

Cancer Science, EarlyView.
The transporter‐associated BNCT strategy using BBCIP with or without BPA according to tumor transporter characteristics. BPA showed greater efficacy in LAT1‐dominant F98 glioma, whereas BBCIP was more effective in SMVT‐high CRL1666 tumors, suggesting the potential utility of transporter‐based boron carrier selection in BNCT.

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

Advanced Optical Materials, Volume 14, Issue 23, 19 June 2026.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Pulse‐to‐pulse analysis of ultra‐high dose per pulse electron beams using beam current transformers

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Ultra‐high dose per pulse (UHDPP) beams have shown to be promising for clinical applications due to their healthy tissue sparing potential. In this radiotherapy modality, a limited number of pulses (often < 25) can deliver the prescribed dose, making pulse‐to‐pulse beam stability essential for accurate dose delivery. In this context,
