From PCV1 to “PCV5”: Genetic Diversity, Evolutionary Dynamics, and Host Adaptation of Porcine Circoviruses

Porcine circoviruses (PCVs) are among the smallest animal viruses that replicate autonomously. What began in 1974 as a single cell culture contaminant, PCV1, now counts five members, PCV1 to PCV5. The newest of these, PCV5, was reported in 2025. Its genome is larger than those of...

Gamma-Irradiated Starch/Chitosan Composite Particles for the Adsorption of Neospora caninum Membrane Proteins as a Potential Vaccine Delivery Platform

Gamma irradiation offers a simple and reagent-free strategy for tailoring the physicochemical properties of starch for the development of functional biomaterials, although its application in protein delivery systems remains largely unexplored. In this study, starch was irradiated...

Beta Atlas: Charting Global Production of Nonconventional β − -Emitters for Targeted Radiopharmaceutical Therapy—Part 1

β-minus particle (β−)–emitting radionuclides have long been central to targeted radiopharmaceutical therapy. Interest in expanding their repertoire beyond conventional options has grown over time, as the need for radionuclides with different emission profiles and theranostic pote...

Global Efforts to Reduce Paediatric Cancer Care Disparities in Radiotherapy: A Decade Change

ABSTRACT Background We present an update on the status, needs and challenges faced by paediatric imaging and radiotherapy (RT) programmes globally after a previous survey conducted by the International Atomic Energy Agency (IAEA) 10 years prior. Methods We developed and distribut...
