Biotransformation, tissue distribution, and persistence of 4-nonylphenol residues in juvenile rainbow trout (Oncorhynchus mykiss).

Effects of nonylphenol on ovarian and testicular tissues in immature rainbow trout (Oncorhynchus mykiss)

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...

Effects of 4-n-nonylphenol and tamoxifen on sGnRH, Estrogen receptor and Vitellogenin gene expression in juvenile rainbow trout

gene expression in juvenile rainbow trout. Short title: Effects of 4-n-nonylphenol and tamoxifen on gene expression in trout. Summary Alkylphenols such as nonylphenol (NP) are one of a wide variety of environmental chemicals reported to have estrogenic effects in both in vitro and in vivo studies. Induction of hepatic vitellogenin (Vg) gene expression is widely used as a biomarker for xenoestro...

Short Communication: Effects of Hypoxic Stress on Electrolyte Levels of Blood in Juvenile Rainbow Trout (Oncorhynchus mykiss)

Effects of 4-n-nonylphenol and tamoxifen on salmon gonadotropin-releasing hormone, estrogen receptor, and vitellogenin gene expression in juvenile rainbow trout.

Alkylphenols such as nonylphenol (NP) are one of a wide variety of environmental chemicals reported to have estrogenic effects in both in vitro and in vivo studies. Induction of hepatic vitellogenin (Vg) gene expression is widely used as a biomarker for xenoestrogen exposure in fish. However, little work has been done to characterize the molecular effects of xenoestrogens on other potential tar...

The Antioxidant Vitamin (A, C, E) and the Lipid Peroxidation Levels in Some Tissues of Juvenile Rainbow trout (Oncorhynchus mykiss, W. 1792) at Different Oxygen Levels

In this study, the malondialdehyde (MDA) levels in the muscle, liver and kidney tissues and the antioxidant vitamin (A, C, E) levels in the muscle tissue of juvenile rainbow trout were investigated under different oxygen levels (3.5 mg O2/l, 4.5 mg O2/l and 7 mg O2/l) at the end of the 8 hour trial. Fish (initial weight and length, 30.19±2.2 g and 13.15±0.22 cm, respectively) were distributed i...
