Attenuating activity of the ovary on LH response to GnRH during the follicular phase of the cycle
(2014)Objective Oestradiol sensitizes the pituitary to GnRH, while gonadotrophin surge attenuating factor (GnSAF) may oppose this action. Using the LH response to GnRH during treatment with FSH as an in vivo bioassay for GnSAF, ... -
Effect of prolonged aflatoxin B-1 administration on blood serum oestradiol-17 beta and progesterone concentrations of goats during the anoestrus period
(2015)The effect of prolonged aflatoxin B-1 (AFB(1)) administration on blood serum oestradiol-17 beta and progesterone concentrations in goats during the anoestrus period was investigated. Thirty Greek indigenous goats were used; ... -
Effects of early vaccination with a gonadotropin releasing factor analog-diphtheria toxoid conjugate on boar taint and growth performance of male pigs
(2014)The aim of this study was to evaluate safety (in terms of detecting possible adverse clinical effects attributable to vaccination), efficacy, and effects on growth performance of a gonadotropin releasing factor analog-diphtheria ... -
Formation of a secondary corpus luteum after ultrasound-guided follicular aspiration in cows
(2000)This paper reports the observed formation of a secondary corpus luteum (CL) in the presence of the cyclic corpus luteum, on the ovaries of a cow after ultrasound-guided follicular aspiration for oocyte recovery. The secondary ... -
Gonadal changes and blood sex steroids levels during natural sex inversion in the protogynous Mediterranean red porgy, Pagrus pagrus (Teleostei : Sparidae)
(2006)Changes in gonadal structure and serum levels of sex steroids were investigated during natural sex inversion from female to male in reared populations of the protogynous Mediterranean red porgy, Pagrus pagrus. Four ... -
Molecular cloning and sequence of Sparus aurata skeletal myosin light chains expressed in white muscle: developmental expression and thyroid regulation
(2001)Two full-length cDNA clones encoding the skeletal myosin light chain 2 (MLC2; 1452 bp) and myosin light chain 3 (MLC3; 972 bp) were isolated from a cDNA library prepared from gilthead sea bream Sparus aurata larvae. The ... -
Oestradiol plus progesterone treatment increases serum leptin concentrations in normal women
(2001)BACKGROUND: Previous studies have alluded to a role for both oestradiol and progesterone in the secretion of leptin from fat cells in the human, although direct evidence has yet to be obtained. The study aim was to assess ... -
Treatment of normal women with oestradiol plus progesterone prevents the decrease of leptin concentrations induced by ovariectomy
(2000)To study the role of oestradiol and progesterone in the secretion of leptin, 21 normally ovulating women were recruited from those scheduled for ovariectomy plus hysterectomy performed in mid-follicular phase of the cycle. ...
