Changes in pituitary sensitivity to GnRH in estrogen-treated post-menopausal women: evidence that gonadotrophin surge attenuating factor plays a physiological role
(2004)BACKGROUND: The purpose of this study was to investigate changes in pituitary response to GnRH in post-menopausal women during substitution treatment with exogenous estrogen and progesterone. METHODS: Seven healthy ... -
Clomiphene in the 21st century
(1998) -
Current and future status of ovulation induction in polycystic ovary syndrome
(1997)Great progress has been achieved during the last 20 years in the field of ovulation induction in patients with polycystic ovary syndrome (PCOS). Clomiphene citrate remains the first line of treatment for all anovulatory ... -
Dose-related effects of prolonged NaHCO3 ingestion during high-intensity exercise
(2006)Purpose: Sodium bicarbonate (NaHCO3) ingestion may prevent exercise-induced perturbations in acid-base balance, thus resulting in performance enhancement. This study aimed to determine whether different levels of NaHCO3 ... -
Evidence of differential control of FSH and LH responses to GnRH by ovarian steroids in the luteal phase of the cycle
(2002)BACKGROUND: It is known that during the follicular phase of the cycle, estradiol sensitizes the pituitary to GnRH. The aim of this study was to determine the role of ovarian steroids in the control of GnRH-induced gonadotrophin ... -
Functional foods: A survey of health claims, pros and cons, and current legislation
(2005)Functional foods stand for a new category of remarkable promising foods bearing properties (i.e. low cholesterol, antioxidant, anti-aging, anticancer, etc.) that have already rendered them quite appealing. Them are many ... -
Genes and Conditions Controlling Mammalian Pre- and Post-implantation Embryo Development
(2015)Embryo quality during the in vitro developmental period is of great clinical importance. Experimental genetic studies during this period have demonstrated the association between specific gene expression profiles and the ... -
High sequence divergence in the 5 ' non-coding region of reference Coxsackie B and ECHO viral strains and clinical isolates revealed by restriction fragment length polymorphism analysis
(2001)We report the restriction fragment length polymorphism (RFLP) patterns of a 440-bp-long 5' non-coding region (5'NCR) amplification target of all 34 reference Coxsackie B and ECHO (enteric cytopathic human orphan) enterovirus ... -
In vitro responsiveness of human post-menopausal myometrium to endothelin-1 and ovarian steroids
(2005)It has been shown in vitro that endothelin 1 (ET1) differentially affects the human myometrial contractility according to the hormonal profile of women. Our purpose was to test the hypothesis that ovarian steroids influence ... -
Increased visfatin in hemodialysis patients is associated with decreased demands for recombinant human erythropoietin
(2013)Background: Studies detected an association between visfatin and markers of iron metabolism in patients with insulin resistance. In this study, such a relation was evaluated in hemodialysis (HD) patients. Also relations ... -
Matrix Metalloproteinases in Respiratory Diseases: From Pathogenesis to Potential Clinical Implications
(2009)Matrix metalloproteinases (MMPs) are zinc-endopeptidases responsible for degradation of the extracellular matrix (ECM) components including basement membrane collagen, interstitial collagen, fibronectin, and various ... -
Molecular and Cellular Mechanisms of Sperm-Oocyte Interactions Opinions Relative to in Vitro Fertilization (IVF)
(2014)One of the biggest prerequisites for pregnancy is the fertilization step, where a human haploid spermatozoon interacts and penetrates one haploid oocyte in order to produce the diploid zygote. Although fertilization is ... -
Molecular and evolutionary analysis of HPV16 E6 and E7 genes in Greek women
(2013)Human papillomavirus type 16 (HPV16) non-European variants have been associated with persistent infection and cervical cancer development, while the L83V variant of the E6 gene has been correlated with the progression of ... -
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 ... -
Ovarian feedback, mechanism of action and possible clinical implications
(2006)The secretion of gonadotrophins from the pituitary in women is under ovarian control via negative and positive feedback mechanisms. Steroidal and non-steroidal substances mediate the ovarian effects on the hypothalamic-pituitary ... -
Ovarian regulators of gonadotropin secretion
(2000)Great progress in the ovarian mechanisms that control gonadotrophin secretion in women has recently been achieved, Estradiol (E-2) is the main component of the ovarian negative effect on basal gonadotropin secretion during ... -
Spectroscopic Evaluation of Glioma Grading at 3T: The Combined Role of Short and Long TE
(2012)Purpose. To evaluate the diagnostic value of 3T H-1-MRS in grading cerebral gliomas using short and long echo times. Methods. (HMRS)-H-1 was performed on 71 patients with untreated cerebral gliomas. Metabolite ratios of ... -
Submaximal Fatigue and Recovery in Boys and Men
(2009)We examined the effects of a sustained submaximal isometric contraction on fatigue and recovery rates in untrained prepubescent boys and men. Fifteen prepubescent boys and 15 men executed an isometric plantar flexion at ...
