The aim of the present investigation was determine whether a standardized Hibiscus sabdariffa calyces aqueous extract has an effect on body weight in an obese animal model induced by the administration of monosodium glutamate. Hibiscus sabdariffa aqueous extract, containing 33.64 mg of total anthocyanins per each 120 mg of extract, was orally administered(More)
Trichomonas vaginalis, a human urogenital tract parasite, is capable of surviving in the male microenvironment, despite of the presence of Zn(2+). Concentrations > 1.6 mM of Zn(2+) have a trichomonacidal effect; however, in the presence of ≤1.6 mM Zn(2+), several trichomonad proteins are up- or down-regulated. Herein, we analyzed the proteome of a T.(More)
Acute hypoglycemic effects of freeze-dried juice of Cucurbita ficifolia Bouché (Cucurbitaceae) fruits were studied in healthy and alloxan-diabetic mice. C. ficifolia fruit administered by intraperitoneal route produced, in a dose-dependent manner, a significant decrease of the glycemia in healthy mice. Although oral route of C. ficifolia fruit juice also(More)
Trichomonas vaginalis is a protozoan parasite that can adapt to the trichomonicidal Zn2+ concentrations of the male urogenital tract microenvironment. This adaptation is mediated by molecular mechanisms, including proteinase expression, that are regulated by cations such as Zn2+. Herein, we characterized the previously identified 50kDa metalloproteinase(More)
Polyamines are involved in the regulation of some Trichomonas vaginalis virulence factors such as the transcript, proteolytic activity, and cytotoxicity of TvCP65, a cysteine proteinase (CP) involved in the trichomonal cytotoxicity. In this work, we reported the putrescine effect on TvCP39, other CP that also participate in the trichomonal cytotoxicity.(More)
