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 ... -
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 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 ... -
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 ... -
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 ... -
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 ... -
Exogenous progesterone for LH surge prevention is redundant in ovarian stimulation protocols
(2021)During ovarian stimulation for IVF–embryo transfer treatment, a premature LH surge may lead to progesterone elevation that disrupts endometrial maturation and affects the probability of pregnancy following fresh embryo ... -
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: ... -
Luteal-phase endocrinology
(2009)The corpus luteum is formed from the pre-ovulatory follicle under the action of the mid-cycle LH surge. LH is the main luteotrophic hormone in women controlling luteal structure and function during the normal menstrual ... -
Making IVF more effective through the evolution of prediction models: is prognosis the missing piece of the puzzle?
(2018)Assisted reproductive technology has evolved tremendously since the emergence of in vitro fertilization (IVF). In the course of the recent decade, there have been significant efforts in order to minimize multiple gestations, ... -
Normal menstrual cycle steroid hormones variation does not affect the blood levels of total adiponectin and its multimer forms
(2015)Objective Plasma total adiponectin reveals a sexual dimorphism indicating that gonadal steroids may be involved in its secretion and/or metabolism. However, results from previous reports are conflicting and data regarding ... -
Physical activity may be a potent regulator of bone turnover biomarkers in healthy girls during preadolescence
(2017)This study investigated the effects of different levels of habitual physical activity (PA) assessed by pedometry on bone turnover markers of preadolescent girls according to a cross-sectional experimental design. Sixty ... -
Single-nucleotide polymorphism rs 175080 in the MLH3 gene and its relation to male infertility
(2015)Purpose: MLH3, a MutL homolog protein in mammals playing a role in DNA mismatch repair, is associated with spermatogenesis and male infertility. The purpose of the present study was to investigate the association of the ... -
Standards of Care in infertility in Europe
(2016)Evidence-based medicine is the principal approach to medical practice. There are several debatable issues in infertility, which require clarification. Over the past 20 years, reliable methodology has been developed for the ... -
A study on ghrelin and LH secretion after short fasting and on ghrelin levels at perioestrual period in dairy cattle
(2019)In two experiments, we studied (a) the changes of LH secretion in heifers under different feeding schedules and (b) total ghrelin concentration at oestrus in cows and heifers. In experiment one, synchronized heifers were ...
