4-Nitro-N-(5-nitro-1,3-thiazol-2-yl)benzamide (1), a new nitazoxanide analog, was synthesized; its chemical structure was confirmed by 1H, 13C NMR, and HRMS. In this study, we evaluated the in vitro activity of compound 1 against Giardia lamblia trophozoites, as well as its in vivo giardicidal activity in a CD-1 mouse model. A pharmacokinetic study in(More)
The impact of restraint stress on the intestinal immune system, particularly on intestinal intraepithelial lymphocytes (i-IEL), has not been described in detail. Thus, the purpose of this study was to assess the effects of restraint stress, including those produced by increases in glucocorticoids and catecholamines, on the population of i-IEL. Mice were(More)
Genome analysis of Entamoeba histolytica predicts the presence of acetyl-CoA carboxylase. Using Western blot, histochemistry, and confocal microscopy, we demonstrated the presence of a biotin-containing protein in the cytoplasm of E. histolytica, with a molecular weight of 136 kDa and biotin–carboxylase activity. This protein probably corresponds to a(More)
