Protein-Based Platform for Purification, Chelation, and Study of Medical Radiometals: Yttrium and Actinium [PDF]

, 2021
Actinium-based therapies could revolutionize cancer medicine but remain tantalizing due to the difficulties in studying Ac chemistry. Current efforts focus on small synthetic chelators, limiting radioisotope complexation and purification efficiencies ...

Skeletal Rearrangements of the C₂₄₀ Fullerene: Efficient Topological Descriptors for Monitoring Stone–Wales Transformations

Mathematics, 2020
Stone–Wales rearrangements of the fullerene surface are an uncharted field in theoretical chemistry. Here, we study them on the example of the giant icosahedral fullerene C240 to demonstrate the complex chemical mechanisms emerging on its carbon skeleton.

Time for action: actinium-225 PSMA-targeted alpha therapy for metastatic prostate cancer - a systematic review and meta-analysis

Theranostics
Rationale: Metastatic prostate cancer in the castration-resistant (mCRPC) setting remains challenging to treat. Prostate-specific membrane antigen (PSMA)-targeted alpha therapy (TAT) is emerging as a promising option.
