Expression and secretion of neurotrophins, including brain-derived neurotrophic factor (BDNF), are regulated also by neuronal activity. Data available in the literature suggest that BDNF central levels are influenced by light and dark. Diurnal changes of BDNF mRNA and protein contents have been demonstrated in the rat central nervous system. Based on these(More)
STUDY OBJECTIVE To assess the roles of instrument diameter (5.0- or 3.5-mm external sheath), uterine distention medium (carbon dioxide [CO(2)] or saline solution), and hysteroscopist experience in diagnostic hysteroscopy. DESIGN Prospective, randomized, multicenter trial (Canadian Task Force classification I). SETTING Two university medical centers in(More)
AIMS The present study aims at evaluating the effect of a 2-week treatment with testosterone (T), dihydrotestosterone (DHT) and estradiol valerate (E(2)V) on brain and plasma beta-endorphin (beta-END) concentrations in gonadectomized rats of both sexes. METHODS Eight groups of female and 8 groups of male Wistar rats were included. For each sex, 1 group of(More)
OBJECTIVE To investigate the effects of dydrogesterone (DYD), a synthetic progestin largely used in hormone therapy, on the central nervous system by studying two markers of the neuroendocrine function: the neurosteroid allopregnanolone and the opioid beta-endorphin. DESIGN Experimental study on animal model. SETTING Academic research environment. (More)
The purpose of this study was to evaluate the effects on hormonal milieu of 1-year therapy with 10 mg/day oral dehydroepiandrosterone (DHEA) or 50 microg transdermal estradiol plus 100 mg/day oral micronized progesterone in a group of 20 healthy postmenopausal women (age=50-58 and years since menopause (ysm)=1-6) and also the effects observed by combining(More)
Cornual pregnancy is an infrequent pathological condition with severe prognosis if not adequately recognized. Ipsilateral salpingectomy represents a unique risk factor for this clinical entity. This article reports a laparoscopically treated spontaneous cornual pregnancy after homolateral salpingectomy for an earlier tubal pregnancy in a condition of(More)
The increased use of hormonal therapies over the last years has led to improve the knowledge of pharmacological, biochemical and metabolic properties of several progestins and their effects in target tissues, such as the central nervous system. Progesterone and synthetic progestational agents are able to modulate the synthesis and release of several(More)
Steroids arriving from the gonads via the circulation modulate brain function, affecting gender differentiation and sexually differentiated behavioral responses, but also the ability of the brain to process, store and retrieve sensory information. Androgens play a pivotal neuroactive role during the "organizational/developmental" phase, mainly in the(More)
The aim of the study was to measure circulating BDNF levels, a neurotrophin recently identified in the ovary, in parallel with estradiol, to verify if assessing this factor could add any predictive value to the outcome of in vitro fertilization. Blood sampling for BDNF and estradiol was performed in 23 subjects undergoing IVF on day 1 (D1), day 8 (D8), day(More)
The aim of this study was to investigate the effects of nomegestrol acetate (NOMAc) on the central nervous system by analyzing the neurosteroid allopregnanolone and the opioid beta-endorphin (beta-endorphin). 104 Wistar female rats were used in this study; one group of fertile and one group of ovariectomized rats were used as control. The others were(More)
