Resonance Raman study of oxoiron(IV) porphyrin π-cation radical complex: Porphyrin ligand effect on ν(Fe=O) frequency.

Resonance Raman (rR) spectroscopy has been applied to study the nature of the iron-oxo (Fe=O) moiety of oxoiron(IV) porphyrin π-cation radical complex (CompI). While the axial ligand effect on the nature of the Fe=O moiety has been studied with rR spectroscopy, the porphyrin ligand effect has not been studied well. Here, we investigated the porphyrin ligand effect on the Fe=O moiety with rR spectroscopy.

Maternal exposure to methylmercury causes an impairment in ependymal cilia motility in the third ventricle and dilation of lateral ventricles in mice offspring.

Background: Although maternal MeHg-exposure causes hydrocephalus in the offspring of mice, its pathogenesis has not been fully explained. In the present study, we examined the issue of how maternal MeHg-exposure in mice affects ependymal ciliary movement in the offspring and whether the lateral ventricles in offspring show dilation.

Methods: Pregnant mice were given drinking water containing 0, 10, or 20 mg/L MeHg, or a single dose of 2 mg/kg MeHg.

Effects of ovarian hormones on GPR120 mRNA expression in mouse pituitary gonadotrophs.

GPR120 is a G-protein-coupled receptor that is activated by long-chain fatty acids. In our previous study, GPR120 expression was detected in gonadotrophs of the mouse anterior pituitary gland. It is well known that the function of anterior pituitary cells is largely under the influence of circulating sex steroids.
