Inhibitory Effect of Submaximal Doses of Ghrelin on Gonadotropin Secretion in Women
(2014)
The effect of ghrelin on gonadotropin secretion has been equivocal. Recent data have shown an inhibitory effect of repeated injections of ghrelin on nocturnal LH and FSH secretion in women. The aim of this study was to ...
Novel aspects of the endocrinology of the menstrual cycle
(2014)
Ovarian control of gonadotrophin secretion is normally achieved via the feedback mechanisms mediated by oestradiol and progesterone. Evidence has been provided that nonsteroidal substances, such as inhibin A and B, participate ...
Melatonin secretion is impaired in women with preeclampsia and an abnormal circadian blood pressure rhythm
(2014)
Non-dipping circadian blood pressure (BP) is a common finding in preeclampsia, accompanied by adverse outcomes. Melatonin plays pivotal role in biological circadian rhythms. This study investigated the relationship between ...
Follicular Fluid Oocyte/Cumulus-Free DNA Concentrations as a Potential Biomolecular Marker of Embryo Quality and IVF Outcome
(2014)
The present prospective study examined the follicular fluid oocyte/cumulus-free DNA concentrations (ff o/c-free DNA) during ovarian stimulation and the possible association between ff o/c-free DNA and embryological results ...
Applicability of self-obtained urine and vaginal samples for HPV-16,-18,-31 and-45 cervical cancer screening in pregnancy: a pilot cross-sectional study
(2014)
Aim:To conduct a pilot cross-sectional study to evaluate the rates of detection of four common high-risk HPV (hr-HPV) types using first-void urine paired with vaginal self-obtained samples in a nonvaccinated population of ...
The impact of cigarette smoking and alcohol consumption on sperm parameters and sperm DNA fragmentation (SDF) measured by Halosperm(A (R))
(2014)
Both cigarette smoking and alcohol consumption are somehow implicated in sperm function, but the impact of these two lifestyle factors on sperm parameters remains controversial. The present study is focused on the impact ...
Attenuating activity of the ovary on LH response to GnRH during the follicular phase of the cycle
(2014)
Objective Oestradiol sensitizes the pituitary to GnRH, while gonadotrophin surge attenuating factor (GnSAF) may oppose this action. Using the LH response to GnRH during treatment with FSH as an in vivo bioassay for GnSAF, ...
Daily supplementation with ghrelin improves in vitro bovine blastocysts formation rate and alters gene expression related to embryo quality
(2014)
Ghrelin is a gastric peptide having regulatory role in the reproductive system functionality, acting mainly at central level. Because the expression of ghrelin system (ghrelin and its receptor) has been detected in the ...
