Histopathology of fathead minnow (Pimephales promelas) exposed to hydroxylated fullerenes
Hydroxylated fullerenes are reported to be very strong antioxidants, acting to quench reactive oxygen species, thus having strong potential for important and widespread applications in innovative therapies for a variety of disease processes. However, their potential for toxicological side effects is still largely controversial and unknown. Effects of hydroxylated fullerenes C60(OH)24 on the fat...
متن کاملAtrazine reduces reproduction in fathead minnow (Pimephales promelas).
Atrazine, the widely used herbicide, has shown to affect the hypothalamus-pituitary-gonad axis in certain vertebrate species, but few studies have examined reproductive effects of this chemical on fish. Our study was designed to evaluate a population endpoint (egg production) in conjunction with histological (e.g., gonad development) and biochemical (e.g., hormone production) phenotypes associa...
متن کاملThe effects of methimazole on development of the fathead minnow, Pimephales promelas, from embryo to adult.
The importance of thyroid hormones in regulating early developmental processes of many amphibian and fish species is well known, but the impacts of exposure to disrupters of thyroid homeostasis during the embryo-larval-juvenile transitions are unclear. To investigate these impacts, fathead minnows, Pimephales promelas, were exposed to a model thyroid axis disrupter, methimazole, an inhibitor of...
متن کاملMorphological sex reversal upon short-term exposure to endocrine modulators in juvenile fathead minnow (Pimephales promelas).
Indications of effects on fish endocrine system have been noted when exposed to effluents of sewage treatment plants and subsequently in the receiving surface waters. For screening purposes, the concentration of vitellogenin (VTG) in plasma is employed to detect potential exposure of fish, to (anti-)estrogenic substances. However, little is known about the variability of VTG determinations and ...
متن کاملEffects of 17alpha-ethinylestradiol in a fathead minnow (Pimephales promelas) gonadal recrudescence assay.
To contribute to the development and evaluation of a practical and cost-effective in vivo testing system for endocrine disruption (specifically environmental estrogens), the effects of 17alpha-ethinylestradiol (EE2) were assessed in a gonadal recrudescence assay with the fathead minnow (Pimephales promelas). Mature male and female fathead minnows were kept first at 15 degrees C on a 8 h light/1...
