Nanobody-Based Theranostic Agents for HER2-Positive Breast Cancer: Radiolabelin...

The overexpression of human epidermal growth factor 2 (HER2) in breast cancer (BC) has been associated with a more aggressive tumor subtype, poorer prognosis and shorter overall survival. In this context, the development of HER2-targeted radiotracers is crucial to provide a non-invasive assessment of HER2 expression to select patients for HER2-targeted therapies, monitor response and identify those who become r...

Advances in the automated synthesis of 6-[18F]Fluoro-L-DOPA

The neurotracer 6-[18F] FDOPA has been, for many years, a powerful tool in PET imaging of neuropsychiatric diseases, movement disorders and brain malignancies. More recently, it also demonstrated good results in the diagnosis of other malignancies such as neuroendocrine tumours, pheochromocytoma or pancreatic adenocarcinoma.The multiple clinical applications of this tracer fostered a very strong interest in the...

Copper-64 Chloride Exhibits Therapeutic Potential in Three-Dimensional Cellular...

Prostate cancer (PCa) is the second most common cancer type in men, and in advanced metastatic stages is considerable incurable. This justifies the need for efficient early diagnostic methods and novel therapies, particularly radiopharmaceuticals with the potential for simultaneous diagnosis and therapy (theranostics). We have previously demonstrated, using monolayer-cultured cells, that copper-64 chloride, a p...

In Vivo Tracking of Extracellular Vesicles by Nuclear Imaging: Advances in Radi...

Extracellular vesicles (EVs) are naturally secreted vesicles that have attracted a large amount of interest in nanomedicine in recent years due to their innate biocompatibility, high stability, low immunogenicity, and important role in cell-to-cell communication during pathological processes. Their versatile nature holds great potential to improve the treatment of several diseases through their use as imaging b...

The Warburg effect in mycobacterial granulomas is dependent on the recruitment ...

Granulomas are the hallmark of mycobacterial disease. Here, we demonstrate that both the cell recruitment and the increased glucose consumption in granulomatous infiltrates during Mycobacterium avium infection are highly dependent on interferon-y (IFN-y). Mycobacterium avium-infected mice lacking IFN-y signalling failed to developed significant inflammatory infiltrations and lacked the characteristic uptake of ...

Optimization and validation of [13N]-NH3 production for clinical studies of pos...

The present work aims to validate the [ 13 N]-NH 3 production for human studies of myocardial perfusion using a cyclotron from a Portuguese public institution and an automatic synthesis module. According to specifications of European Pharmacopeia (Ph. Eur.) 8.2., 3 consecutives batches were evaluated for this purpose. Results showed a clear and colorless product and pH values between 4,5 e 8,5. The chemical pur...
