Abstract:
The superoxide dismutases (SODs) are first-line enzymatic antioxidants that dismute superoxide anion (O(2)(-)*) to produce hydrogen peroxide (H(2)O(2)). The primary objective was to characterize, by western blot analysis, the expression of two SODs, the cytosolic (Cu,ZnSOD or SOD1) and the mitochondrial (MnSOD or SOD2) forms in three sections of the oviduct, i.e. isthmus (I), ishtmic-ampullary junction (IA), and ampulla (A), during the estrous cycle. The Cu,ZnSOD and MnSOD proteins were mostly expressed in the ampulla (I

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
