background: gts, ptsm and atsm are bis-thiosemicarbazone ligands used in the preparation of copper radiopharmaceuticals. chemical structure of these materials indicates that they should have radio-protective effects. objective: to study the radio-protective effects of gts, ptsm and atsm. methods: this study has focused on radio-protective effects of these compounds at different doses (20, 40 an...
UNLABELLED The natural phytoestrogen genistein is known as protein kinase inhibitor and tumor suppressor in various types of cancers. We studied its antitumor effect in two different xenograft models using positron emission tomography (PET) in vivo combined with ex vivo histology and nuclear magnetic resonance (NMR) metabolic fingerprinting. PROCEDURES A431 and Colo205 tumor-bearing mice were...
Positron emission tomography (PET) imaging agents that detect amyloid plaques containing amyloid beta (Aβ) peptide aggregates in the brain of Alzheimer's disease (AD) patients have been successfully developed and recently approved by the FDA for clinical use. However, the short half-lives of the currently used radionuclides 11C (20.4 min) and 18F (109.8 min) may limit the widespread use of thes...
