Adrenal, thyroid and gonadal axes are affected at high altitude
(2018)Humans cannot live at very high altitude for reasons, which are not completely understood. Since these reasons are not restricted to cardiorespiratory changes alone, changes in the endocrine system might also be involved. ... -
Alterations in xenobiotic-metabolizing enzyme activities across menstrual cycle in healthy volunteers
(2019)The purpose of the study was to determine whether the in vivo activities of drug-metabolizing enzymes CYP1A2 and CYP2A6, xanthine oxidase (XO), and N-acetyltransferase-2 (NAT2) vary across the menstrual cycle. Forty-two ... -
Association of Pathology Markers with Somatostatin Analogue Responsiveness in Acromegaly
(2022)Background. Somatotroph adenomas (SAs) exhibit a variable responsiveness to somatostatin analogue (SS-a) treatment, a process that is not well understood. We investigated established and novel histological markers as ... -
Autism spectrum disorder, anxiety and severe depression in a male patient with deletion and duplication in the 21q22.3 region: A case report
(2019)In this report, a patient carrying a 650 kb deletion and a 759 kb duplication of chromosomal 21q22.3 region was described. Facial dysmorphic features, hypotonia, short stature, learning impairment, autism spectrum disorder, ... -
Changes in pituitary response to gonadotropin releasing hormone following bilateral ovariectomy in women treated with follicle-stimulating hormone
(1996)Superovulation induction in women attenuates the pituitary response to gonadotropin-releasing hormone (GnRH). The aim of this study was to assess the duration of the suppressing activity of the ovaries on the pituitary. ... -
Changes of serum sclerostin and Dickkopf-1 levels during the menstrual cycle. A pilot study
(2016)Studies in postmenopausal women have identified sclerostin as a strong candidate for mediating estrogen effects on the skeleton. The effects of estradiol on sclerostin and Dickkopf-1 in younger women remain unclear. The ... -
Corifollitropin alfa compared with follitropin beta in GnRH-antagonist ovarian stimulation protocols in an unselected population undergoing IVF/ICSI
(2017)Recombinant DNA technologies have produced Corifollitropin alfa (CFa) used during IVF/ICSI in order to keep the circulating FSH levels above the threshold necessary to support multi-follicular growth for a week. In this ... -
The effect of a GnRH antagonist on follicle maturation in normal women
(2019)Research question: Ganirelix is a gonadotrophin-releasing hormone (GnRH) antagonist used for the prevention of premature LH surge during ovarian stimulation. What is the impact of ganirelix on follicle maturation in normal ... -
Effect of adiponectin on estradiol and progesterone secretion from human luteinized granulosa cells in vitro
(2021)Ιnformation on the role of adiponectin in human ovarian steroidogenesis is limited. The present study aimed to investigate the effect of different doses of adiponectin on the secretion of estradiol and progesterone by human ... -
The Effect of Metformin on the Endometrium of Women with Polycystic Ovary Syndrome
(2019)Objectives: To investigate the effect of metformin on endometrial receptivity in women with polycystic ovary syndrome (PCOS). Methods: Twenty volunteer women with polycystic ovaries and oligomenorrhea were prospectively ... -
Effect of mifepristone on folliculogenesis in women treated with recombinant FSH
(1997)Objective: To study the mechanism through which mifepristone interrupts folliculogenesis. Design: Normally ovulating women undergoing donor intrauterine insemination (IUI) treatment were investigated during two menstrual ... -
Effect of resistin on estradiol and progesterone secretion from human luteinized granulosa cells in culture
(2019)Information on the role of resistin on steroidogenesis is limited to animal studies. The aim of this study was to investigate the effect of various doses of resistin on estradiol and progesterone secretion from human ... -
Efforts to create an artificial testis: Culture systems of male germ cells under biochemical conditions resembling the seminiferous tubular biochemical environment
(2005)Induction of meiotic and post-meiotic alterations of male germ cells in vitro has been the target of several research efforts since 1960. However, to date, the establishment of an ideal culture system in which spermatogonial ... -
The endocrine effects of multiple folliculogenesis
(2011)Induction of multiple follicular development is a common practice in IVF programmes. Nevertheless, such an approach is not without implications. Apart from the high multiple pregnancy rate, marked changes in the secretion ... -
Endocrine resistance and epigenetic reprogramming in estrogen receptor positive breast cancer
(2021)Despite the enormous advances during the last three decades, breast cancer continues to be the most frequent type of cancer as well as one of the most frequent cancer-related causes of death in women. Therapeutic management ... -
Ghrelin suppresses the GnRH-induced preovulatory gonadotropin surge in dairy heifers
(2016)Ghrelin, a known growth hormone (GH) secretagogue, alters gonadotropin secretion in many species. Our objectives were to study the effects of ghrelin, on GH, LH, FSH secretion, and on luteal function of the ensuing estrous ... -
In early pubertal boys, testosterone and LH are associated with improved anti-oxidation during an aerobic exercise bout
(2019)Purpose: To investigate the association of the hypothalamic-pituitary-testicular (HPT) axis with pro- and anti- oxidation, in relation to puberty and obesity in boys, before and after an aerobic exercise bout. Methods: ... -
