Effect of an OT antagonist on the control of the midcycle LH surge in women
Vanakara, P.; Dafopoulos, K.; Papastergiopoulou, L.; Kallitsaris, A.; Papageorgiou, I.; Messinis, I. E. (2009)P>Objective Data in women regarding the role of OT in LH secretion during the LH surge are conflicting. As in previous studies blood samples for LH measurements were taken infrequently, we re-examined this matter in women ... -
The effect of estrogens on plasma ghrelin concentrations in women
Dafopoulos, K.; Chalvatzas, N.; Kosmas, G.; Kallitsaris, A.; Pournaras, S.; Messinis, I. E. (2010)Background: Data regarding the possible effects of estrogen on ghrelin secretion in humans are limited and contradictory. Aim: To investigate the effect of estradiol (E2) on ghrelin levels in normal pre- and post-menopausal ... -

Dafopoulos, K.; Chalvatzas, N.; Kristo, I.; Kallitsaris, A.; Lialios, G.; Messinis, I. E. (2006) -
Effect of ovarian hormones on serum adiponectin and resistin concentrations
Chalvatzas, N.; Dafopoulos, K.; Kosmas, G.; Kallitsaris, A.; Pournaras, S.; Messinis, I. E. (2009)Objective: To investigate the effect of ovarian hormones on adiponectin and resistin levels in women.

Effects of clomiphene and raloxifene on gonadotrophin secretion in postmenopausal women: evidence of nongenomic action
Garas, A.; Trypsianis, G.; Kallitsaris, A.; Milingos, S.; Messinis, I. E. (2004)OBJECTIVE To evaluate the effect of raloxifene (R) and clomiphene (Cl) on FSH and LH secretion in postmenopausal women.
