In vitro reduction of zearalenone to β-zearalenol by rainbow trout (Oncorhynchus mykiss) hepatic microsomal and post-mitochondrial subfractions
Mycoestrogen zearalenone (ZEA) is found in human foods and animal feeds. Its estrogenic potencymainly depends on its biotransformation fate. The hepatic biotransformation of ZEA in rainbow trout wasinvestigated in this study. Various concentrations of ZEA were separately incubated with the hepaticmicrosomal and post-mitochondrial sub-fractions in the presence of NADPH, and the metabolites wered...
متن کاملThe effects of activated-omental extract on nuclear and cytoplasmic in vitro maturation of rat oocytes
Objective: The role of growth factors, including vascular endothelial growth factor of activated omentum on mitosis is clearly known, though not on all the aspects of in vitro oocyte maturation. This study was designed to assess the effect of activated-omental extract (AOE) on in vitro maturation (IVM) of rat cumulus-oocyte complexes (COCs). Materials and Methods: In this experimental study, th...

Nonylphenol (NP) is an endocrine disrupting chemical widely used in industrial practices worldwide. It is estimated that large amounts of this estrogenic compound annually discharged into aquatic ecosystem. So this study was conducted to determine the effects of this pseudoestrogen compound on gonadal maturation and histopathology of ovarian and testicular tissues of rainbow trout, Oncorhynchus...
متن کاملDose-dependent effects of Gundelia Tournefortii root extract on meiosis resumption and in vitro maturation in mouse immature oocytes
Background & Aim: Oocytes in vitro maturation is an enormously promising technology for the treatment of infertility, yet its clinical application remains limited owing to poor success rates. Therefore this study was designed to determine the effect of Gundelia Tournefortii root hydro alcoholic extract as a source of antioxidant on in vitro oocyte maturation. Experimental: In this stu...
