Advanced Science, EarlyView.Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

Advanced Science, EarlyView.Monoclonal antibodies are powerful anticancer therapeutics targeting tumor‐associated antigens. Mass spectrometry enables precise and accurate quantification of mAbs in tumor plasma and healthy organs. Unlike ligand binding assay and radioactivity, mass spectrometry does not suffer from matrix effects and labelling artefacts while facilitating method ...

Phosphogypsum and its potential use in Croatia: challenges and opportunities
Arhiv za Higijenu Rada i Toksikologiju, 2021 Phosphogypsum (PG) is a waste by-product (residue) originating from the production of phosphoric acid and phosphate fertilisers. PG contains chemical and radioactive impurities, which is why it is mostly stockpiled in controlled areas.

Advanced Science, EarlyView.Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized
