Karamouti, M.; Kollia, P.; Karligiotou, E.; Kallitsaris, A.; Prapas, N.; Kollios, G.; Seferiadis, K.; Vamvakopoulos, N.; Messinis, I. E. (2003)Whether leptin is secreted by the human ovary is not known. The available data on leptin gene (ob gene) expression by human granulosa cells are conflicting. The aim of the present study was first to re-examine the expression ... -

Attenuating activity of the ovary on LH response to GnRH during the follicular phase of the cycle
Dimitraki, M.; Messini, C. I.; Dafopoulos, K.; Gioka, T.; Koutlaki, N.; Garas, A.; Georgoulias, P.; Messinis, I. E. (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, ... -

Dimitraki, M.; Koutlaki, N.; Gioka, T.; Messini, C. I.; Dafopoulos, K.; Anifandis, G.; Messinis, I. E. (2015)ObjectiveIt has been reported that the positive feedback mechanism of oestrogens and progesterone is preserved, although attenuated, in late postmenopausal years. Whether this is also true for the positive feedback effect ... -
