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.

Elimination Half-Life of Anti-Mullerian Hormone
Griesinger, G.; Dafopoulos, K.; Buendgen, N.; Cascorbi, I.; Georgoulias, P.; Zavos, A.; Messini, C. I.; Messinis, I. E. (2012)Context: Anti-Mullerian hormone (AMH) is a glycoprotein that is secreted by the granulosa cells in the human ovary. In the postpubertal female, circulating AMH reflects the number of follicles within the ovary. It is ... -
Elimination half-life of anti-Mullerian hormone in the human
Griesinger, G.; Dafopoulos, K.; Buendgen, N.; Cascorbi, I.; Georgoulias, P.; Zavos, A.; Messinis, C.; Diedrich, K.; Messinis, I. (2011) -
The Emerging Roles of Adiponectin in Female Reproductive System-Associated Disorders and Pregnancy
Angelidis, G.; Dafopoulos, K.; Messini, C. I.; Valotassiou, V.; Tsikouras, P.; Vrachnis, N.; Psimadas, D.; Georgoulias, P.; Messinis, I. E. (2013)Adiponectin, the most abundant adipose-released cytokine, has an important role in metabolism, primarily through reducing insulin resistance. Reproductive functions are known to be influenced by energy balance and adiponectin ... -
Endocrine, paracrine, and autocrine placental mediators in labor
Iliodromiti, Z.; Antonakopoulos, N.; Sifakis, S.; Tsikouras, P.; Daniilidis, A.; Dafopoulos, K.; Botsis, D.; Vrachnis, N. (2012)Considering that preterm birth accounts for about 6-10% of all births in Western countries and of more than 65% of all perinatal deaths, elucidation of the particularly complicated mechanisms of labor is essential for ... -
Endothelin-3 and PRL levels in the maternal and fetal circulation at delivery
Dafopoulos, K.; Boli, A.; Kallitsaris, A.; Malamitsi-Puchner, A.; Kollios, G.; Messinis, I. E. (2007)Objective: The aim of the present cross-sectional study was to test the hypothesis that endothelin-3 (ET-3) is involved in PRL secretion via systemic hormonal interaction during labor. Materials and methods: Fifty healthy ... -
Endothelin-3 and prolactin levels in the maternal and fetal circulation at delivery

Evidence that termination of the estradiol-induced luteinizing hormone surge in women is regulated by ovarian factors
Dafopoulos, K.; Mademtzis, I.; Vanakara, P.; Kallitsaris, A.; Stamatiou, G.; Kotsovassilis, C.; Messinis, I. E.

Objective: The objective of the study was ... -
