Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Anifandis, G.; Messinis, I. E. (2010)Objective: To investigate the effect of bromocriptine on ghrelin-induced PRL secretion in women. Design: Longitudinal study. Setting: University hospital. Patient(s): Ten healthy, normally cycling women. Intervention(s): ... -
Changes in ghrelin and adipocytokines levels in ovariectomized premenopausal women treated with estrogen
Dafopoulos, K.; Chalvatzas, N.; Kristo, I.; Kallitsaris, A.; Mademtzis, I.; Messinis, I. E. (2006) -
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 ... -
Effect of ghrelin and metoclopramide on prolactin secretion in normal women
Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Anifandis, G.; Messinis, I. E. (2010) -
Effect of ghrelin and metoclopramide on prolactin secretion in normal women
Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Anifandis, G.; Messinis, I. E. (2011)Background: Administration of ghrelin to women stimulates the secretion of PRL but the mechanism is not known. Aim: The aim of the study was to investigate the effect of the dopamine receptor blocker, metoclopramide, on ... -
Effect of Ghrelin and Thyrotropin-releasing Hormone on Prolactin Secretion in Normal Women
Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Anifandis, G.; Messinis, I. E. (2010)It is known that ghrelin stimulates the secretion of prolactin in women. The aim of this study was to examine the effect of exogenous thyrotropin-releasing hormone (TRH) on ghrelin-induced prolactin release. Ten healthy ... -
Effect of ghrelin on gonadotrophin secretion in women during the menstrual cycle
Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Messinis, I. E. (2009)It has been suggested that ghrelin may affect reproduction in animals by decreasing pituitary LH secretion. The role of ghrelin on LH secretion in women has not been investigated. Our aim was to assess the effect of ghrelin ... -
Effect of induced follicular phase estradiol concentrations on ghrelin and adipocytokines levels in postmenopausal women
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. Design: Experimental study. Setting: University hospital. Patient(s): Thirteen normally cycling women (7 in group I and ... -
Effect of the Position of the Polar Body During ICSI on Fertilization Rate and Embryo Development
Anifandis, G.; Dafopoulos, K.; Messini, C. I.; Chalvatzas, N.; Messinis, I. E. (2010)This prospective study was designed to evaluate and clarify further whether the position of the polar body (PB) in relation to injection site during intracytoplasmatic sperm injection (ICSI) has an impact on fertilization ... -
Growth hormone and prolactin response to ghrelin during the normal menstrual cycle
Messini, C. I.; Dafopoulos, K.; Chalvatzas, N.; Georgoulias, P.; Messinis, I. E. (2009)Objective It has been suggested that exogenous oestradiol augments ghrelin-induced growth hormone (GH) secretion in postmenopausal women. Whether endogenous oestrogens exert a similar effect during the normal menstrual ... -
Metformin reduces the expression of corticotrophin releasing hormone and urocortin in the endometrium of normal women
Dafopoulos, K.; Vrekoussis, T.; Chalvatzas, N.; Messini, C. I.; Kalantaridou, S.; Georgoulias, P.; Messinis, I. E.; Makrigiannakis, A. (2012) -

Dafopoulos, K.; Vrekoussis, T.; Chalvatzas, N.; Messini, C. I.; Kalantaridou, S. N.; Georgoulias, P.; Messinis, I. E.; Makrigiannakis, A. (2013)Objective: To investigate the effect of metformin administration on the expression of endometrial corticotrophin-releasing hormone (CRH) and urocortin (UCN) in the midluteal phase of the cycle. Design: Experimental study, ... -
