Oropouche virus (OROV), first detected in Trinidad and Tobago in 1955, was historically confined to the Brazilian Amazon Basin. However, since late 2022, an increasing number of OROV cases have been reported across various regions of Brazil as well as in urban centers in Bolivia, Ecuador, Guyana, Colombia, Cuba, Panama, and Peru. In collaboration with Central Public Health Laboratories across Brazil, we integra...

The present work describes the preparation, characterization and labelling of conventional and surface-modified nanocapsules (NC) with 99mTc-HMPAO. The size, size distribution and homogeneity were determined by photon correlation spectroscopy (PCS) and zeta potential by laser doppler anemometry. The morphology and the structural organization were evaluated by atomic force microscopy (AFM). The stability and rel...
