ANTIPARASITIC ACTIVITY OF SILVER AND COPPER OXIDE NANOPARTICLES AGAINST ENTAMOEBA HISTOLYTICA AND CRYPTOSPORIDIUM PARVUM CYSTS.

Nanoparticles (NPs) have received more attention as antiparasitic agents. In the present study, silver and copper nanoparticles were synthesized and characterized using scanning electron microscopy (SEM), transmission electron microscope (TEM) and X-ray fluorescence (XRF). The antiparasitic activity of Ag and CuO nanoparticles were tested against two of the most environmentally spread parasites in Egypt (Entamoeba histolytica and Cryptosporidium parvum).

Imaging findings of radiation enteritis.

In this report the authors describe the imaging features of subacute and chronic radiation enteritis in two patients. Although surgery remains the definitive treatment of complicated chronic radiation enteritis, the potential role of interventional techniques that can be used for management of poor surgical candidates is discussed.
